Abstract

An electric treadmill comprises a base, an armrest, a run belt, a protective pad, and a reduction belt; the run belt sleeves a driving roller and a driven roller to form a belt drive mechanism; two reduction wheels are disposed at two axial ends of the driven roller respectively; stoppers on the reduction wheels are used with anti-skid cylinders to limit the speed of the tread mill. Falling injury is reduced by the use of a protective pad arranged below the armrest; pain is eased by buffering of the protective pad when a user falls onto the protective pad; the reduction belt is disposed at the rear of the treadmill, the user can step into the reduction belt in time to retard backward skid of the body before the user falls, friction of the human body with equipment and ground is reduced, and bruises are avoided. Meanwhile, the stoppers and the anti-skid cylinders are disposed on the driven roller, the stoppers are retracted into the reduction wheels through springs, centrifugal force that the stoppers experience is larger than pretension force of the springs when the speed is too high, the springs can pop out and enter the anti-skid cylinders exactly so that the speed is reduced, and accidents caused by the excessively high speed are avoided.

Description

A kind of treadmill

Technical field

The present invention relates to a kind of physical training auxiliary appliance, especially relate to a kind of treadmill.

Background technology

Treadmill is a kind of body-building apparatus generally using; can be for warm-up that human body is intake; also can allow user carry out physical exercise simultaneously; the crowd that treadmill is convenient to be arranged on indoor time less easy to use performs physical exercise; because a lot of users have safe guidance often can run into person taking exercise, do not run and accidentally fall down easy tumble injury arm; can paddle backward along treadmill, simultaneously sometimes treadmill there will be hypervelocity and accidents caused simultaneously.

Summary of the invention

The object of the invention is for solving the easily accidents caused problem with falling down rear easy tumble injury of hypervelocity of existing treadmill, a kind of treadmill is provided, the present invention can reduce tumble injury by being arranged on the neonychium of handrail below, by the buffering of falling down on neonychium, palliate the agonizing sufferings, at treadmill rear, be provided with deceleration strip simultaneously, if fall down to pedal in time into deceleration strip reducing human, slide backward, alleviated the friction between human body and equipment and ground, thereby avoid scratch, on driven running roller, be provided with block and anti-slide cartridge simultaneously, by spring, block is shunk in ratio wheel, when excessive velocities, the centrifugal force that block is subject to is greater than the pretightning force of spring, thereby anti-slide cartridge reducing speed is inserted in all right ejection of spring so, avoid the accident causing due to excessive velocities.

The present invention is the deficiency solving the problems of the technologies described above, and the technical scheme adopting is:

A kind of treadmill, comprise base, handrail, run band, neonychium and deceleration strip, handrail and deceleration strip are distributed in the two ends of base, deceleration strip is just consistent with the width that runs band, running band is arranged on base, and coordinate drive to run band rotation by driven running roller and the active roll being fixed on base, thereby run, band is set in driven running roller and active roll forms belt gear, neonychium is arranged on handrail on base and runs on the position between band, the below of arm when being just positioned at person taking exercise and using, described active roll is connected with motor, the axle head of active roll is connected with the output of motor by shaft coupling, driven running roller is all connected with base side wall by bearing with active roll two ends, and by being arranged on the end cap seal on sidewall, base upper surface is respectively provided with a removable cover near running place, band two ends, removable cover just lid is located on the hole of running with both sides, removable cover below is connected with a connecting plate I, an anti-slide cartridge is installed on connecting plate I, described driven voller wheel shaft to two ends be respectively provided with a ratio wheel, ratio wheel diametric(al) offers groove, in groove, be provided with the spring with pretightning force, spring one end is fixed in groove, on the other end, be connected with a block, block shrinks in groove by the pretightning force of spring, projection when block is positioned at vertical position on removable cover is positioned at anti-slide cartridge just, by the engagement limits treadmill speed of block and anti-slide cartridge.

Described anti-slide cartridge comprises that a cylinder-like structure and cylinder-like structure outer bottom are welded with a connecting plate II who coordinates with connecting plate I, between connecting plate I and connecting plate II, be bolted, and can mutually regulate between connecting plate I and connecting plate II, to change the distance between anti-slide cartridge and ratio wheel, thereby change the speed limit upper limit of treadmill, because the distance that after distance changes, block stretches out can change, thereby centrifugal force is changed, make the change of reaching the standard grade of the speed of driven running roller.

On described removable cover, be provided with the handle that facilitates mobile removable cover.

The invention has the beneficial effects as follows: the present invention can reduce tumble injury by being arranged on the neonychium of handrail below, by the buffering of falling down on neonychium, palliate the agonizing sufferings, at treadmill rear, be provided with deceleration strip simultaneously, if fall down to pedal in time into deceleration strip reducing human, slide backward, alleviated the friction between human body and equipment and ground, thereby avoid scratch, on driven running roller, be provided with block and anti-slide cartridge simultaneously, by spring, block is shunk in ratio wheel, when excessive velocities, the centrifugal force that block is subject to is greater than the pretightning force of spring, thereby anti-slide cartridge reducing speed is inserted in all right ejection of spring so, avoid the accident causing due to excessive velocities.

The specific embodiment

Shown in figure, the specific embodiment is as follows:

A kind of treadmill, comprise base 1, handrail 2, race is with 4, neonychium 3 and deceleration strip 5, handrail 2 and deceleration strip 5 are distributed in the two ends of base 1, deceleration strip 5 is just consistent with the width that runs band, race is with 4 to be arranged on base 1, and coordinate drive race to be with 4 rotations by driven running roller 7 and the active roll 6 being fixed on base 1, thereby race is with 4 to be set in driven running roller 7 and active roll 6 formation belt gears, neonychium 3 is arranged on handrail 2 on base 1 and runs with on the position between 4, the below of arm when being just positioned at person taking exercise and using, described active roll 6 is connected with motor 9, the axle head of active roll 6 is connected with the output of motor 9 by shaft coupling 10, driven running roller 7 is all connected with base 1 sidewall by bearing 12 with active roll 6 two ends, and by being arranged on the end cap seal on sidewall, base 1 upper surface is with 4 places, two ends to be respectively provided with a removable cover 8 near running, removable cover 6 just lid is located on the hole of running with 4 both sides, removable cover 8 belows are connected with a connecting plate I801, an anti-slide cartridge 13 is installed on connecting plate I801, the axial two ends of described driven running roller 7 are respectively provided with a ratio wheel 11, ratio wheel 11 diametric(al)s offer groove, in groove, be provided with the spring 15 with pretightning force, spring 15 one end are fixed in groove, on the other end, be connected with a block 14, block 14 shrinks in groove by the pretightning force of spring 15, projection when block 14 is positioned at vertical position on removable cover 8 is positioned at anti-slide cartridge 13 just, engagement limits treadmill speed by block 14 with anti-slide cartridge 13.
