Abstract

The invention provides a pull rope belt, wherein the degree of tightness of an acting object is controlled through application of different force bearing situations between multiple single knots and rope belts passing the single knots and through changing of position relations among parts of the rope belts. The pull rope belt is characterized in that three or more than three single knots are tied successively on a rope belt a; one rope belt head of a rope belt b successively passes a rope belt ring formed by each single knot on the rope belt a, wherein the course is started from one of the two single knots located on the two farthest ends of the rope belt a; and the other rope belt head of the rope belt b does not pass through the single knots. The pull rope belt is connected to the acting object properly; according to the characteristic that the rope belts on two ends of the single knot are tightened due to pull force in opposite directions, the rope belt b is controlled to pass through the rope belt knots on the rope belt a through slide friction force and static friction force between the multiple single knots and the rope belts passing through the knots; and the length of the rope belts of the rope belt b located on both sides of the rope belt knot can be changed, so that the tightness degree of the acting object can be controlled.

Description

Stay cord band

Art

The present invention relates to a kind of by utilize multiple unijunction from through the different stressing conditions its rope band, rely on the position relationship of changing section rope band, carry out the rope band device of control action object degree of tightness, especially need not be to solve rope band knot to can be achieved with the stay cord band of required degree of tightness repeatedly.

Background technology

At present, the known rope band for controlling degree of tightness, it is by being solution rope band knot repeatedly or relying on metal or duroplasts part to realize, such as waist belt, shoestring, braces etc., it is the situation solving and there will be fast knot and eliminating stagnation time rope band has repeatedly, and metal and duroplasts flexibility are bad, easily collide with health.

Summary of the invention

In order to allow rope band become simple and convenient for the situation of degree of tightness, the present invention provides a kind of stay cord band, this stay cord band need not be to solve rope band knot repeatedly, also not against metal and duroplasts part, only need to control the relative position that part rope band ties with rope band and can be achieved with required degree of tightness.

The technical solution adopted for the present invention to solve the technical problems is: be the unijunction having 3 or more than 3 quantity on a rope band, one rope band head of b rope band is from the beginning of one of them unijunction being positioned on a rope band two unijunctions at two ends, passing sequentially through the rope band circle formed by each unijunction on a rope band in order, another rope band head of b rope band does not pass through unijunction.Rope band is laterally disposed, to be positioned at that unijunction leftmost for left unijunction, being positioned at that unijunction rightmost is right unijunction, the rope band being positioned at left unijunction left-hand component is left half rope band, the rope band being positioned at right unijunction right-hand component is right half rope band, the right half rope band of the left half rope band of a rope band Yu b rope band can be connected respectively to 2 points of effective object, by controlling the rope band length between two junction points, carry out the degree of tightness of control object.nullWhen applying direction power to the right to left unijunction，The left half rope band simultaneously giving b rope band applies the power of a left direction，Left unijunction is made to do direction relative motion to the right relative to left section of part band of b rope band，Carrying out along with motion，From the beginning of left unijunction，Each unijunction moves right together with touching then with next unijunction the most successively，B rope band is finally made to be positioned at the rope band on the right of right unijunction by all unijunctions，Move into place in the left side of left unijunction，The right half rope band making b rope band shortens，And the left half rope band length of a rope band is constant，Thus the rope band between two junction points being connected with the right half rope band of b rope band by the left half rope band of a rope band shortens，Receive short reach desirable degree after，Remove the power above applied，Then the left half rope band giving a rope band applies the pulling force of a left direction，The right half rope band simultaneously giving a rope band applies the pulling force of a right direction，Stretch the rope band between unijunction and unijunction，Tension unijunction，Then pulling force is removed，Complete tightening process.The feature of unijunction is that two ends rope band can be become the tightest by the biggest unijunction of reversal interlocking relay, unijunction and the biggest through the coefficient of friction its rope band.nullIf effective object is want by two junction points to a、B rope band applies reversal interlocking relay and increases the rope band length between two junction points，The left half rope band now giving a rope band applies the pulling force of left direction，The right half rope band simultaneously giving b rope band applies the pulling force of right direction，Because right unijunction and there is coefficient of friction through its b rope band，So the rope band on the right unijunction left side can be by direction pulling force to the right，This direction pulling force to the right acts on jointly with the direction of applying pulling force to the left on left section of rope band of a rope band，Other unijunctions making the right unijunction left side become tight，Thus increase other unijunction and through the coefficient of friction their b rope band，The most each unijunction and through the frictional force produced its b rope band，The coefficient of friction between other unijunctions of its left side and b rope band will be increased，Make by the right side to left unijunction big with one ratio of frictional resistance one together of b rope band，Because the left half rope band length of a rope band is constant，The right half rope band of b rope band so elongated that to overcome the stiction between all unijunctions and b rope band simultaneously，So rope band length between two junction points receive short after，It is difficult to because effective object passes through two junction points to a、B rope band apply reversal interlocking relay and elongated.nullAnd want to elongate the rope band between two junction points，Only need to apply direction power to the left to right unijunction，The right half rope band simultaneously giving b rope band applies direction power to the right，Right unijunction is made to do direction relative motion to the left relative to the right half rope band of b rope band，From the beginning of being positioned at the rightest first unijunction，It is moved to the left together with touching then with next unijunction the most successively，B rope band is finally made to be positioned at the rope band on the left side of left unijunction also by all unijunctions，Move into place in the right of right unijunction，Along with the right half rope band of b rope band is elongated，And the left half rope band length of a rope band is constant，Rope band between two junction points is elongated，After elongation reaches required degree，Remove the power above applied，Then the left section of rope band giving a rope band applies the pulling force of a left direction，The right section of rope band simultaneously giving a rope band applies the pulling force of a right direction，Stretch the rope band between unijunction and unijunction，Tension unijunction，Then pulling force is removed，Complete elongation process.Draw short and elongate during, stiction between unijunction and b rope band is the most single to be overcome one by one, and the when of only stretching rope band between unijunction, the rope band of unijunction the right and left can be by reversal interlocking relay, because the unijunction after Hua Donging can fluff scattered, thus reduce and by the coefficient of friction between its rope band, so stretching and pull loose process leicht fallen D/A.

The invention has the beneficial effects as follows, can be to solve rope band knot or utilize metal, duroplasts part repeatedly being not required to, by controlling the mobile realization binding to object of rope band and rope band knot, degree of tightness, simple in construction, easy to operate.
