Abstract
The invention discloses a flexible moving protection cover for a small dental grinding instrument. The protection cover comprises a central sleeve arranged at the center, a circular connection edge surrounding the outside of the central sleeve and a flexible cover. The flexible cover is connected between the central sleeve and the circular connection edge, and a cover structure is formed in a circular region between the central sleeve and the circular connection edge. The flexible moving protection cover for the small dental grinding instrument is free of folds and creases in the natural state, easy to manufacture and maintain and clean daily, free of deformation concentration points during use, not prone to damage and long in service life.
Description
Technical field
The present invention relates to protective cover, particularly relate to a kind of small-sized dentistry beveller compliant motion protective cover.
Background technology
Current artificial tooth extensively adopts the high-abrasive material such as alloy or pottery, in process, cutter and friction of workpiece produce more heat transfer, cooling system need be arranged cool to prevent heat to be passed to lathe bed to cutter and work pieces process position and affect quality of fit and structure between each parts, be generally water-cooling system, cost is lower, good cooling results, the main shaft of small-sized dentistry beveller is by extending out to above workbench in housing, housing is provided with the mouth of stepping down stretching out for main shaft and move in space, accordion guard shield is adopted to be arranged on main shaft in prior art and the edge of mouth of stepping down, water-cooling system work can be avoided to produce fluid spills pollute main shaft drives parts and corrode, but the distortion of accordion guard shield mainly concentrates on its folding line place during motion of main shaft, easily there is crackle and damage afterwards in long-time use, and be not easily found, very harmful to equipment, be unfavorable for the regular maintenance of equipment, and the guard shield consumptive material of accordion is many, not easily machine-shaping, manufacturing cost is higher.
Summary of the invention
In view of this, the object of this invention is to provide a kind of small-sized dentistry beveller compliant motion protective cover, corrugationless and folding line under nature, easily make and regular maintenance cleaning, without distortion centrostigma during use, not fragile, service life is of a specified duration.
Small-sized dentistry beveller compliant motion protective cover of the present invention, comprises the center at the center of being located at, is surrounded on the annular fillet of center outside and is connected between center and annular fillet and annular region between center and annular fillet forms the flexible cover body of hood-like structure.
Further, the thickness of described flexible cover body is thinning gradually to edge from center.
Further, described center, flexible cover body and annular fillet are wholely set.
Further, described flexible cover body is bowl structure, and the rear end axially docking of the Center-to-Center cover of flexible cover body, annular fillet connects with the edge of flexible cover body.
Further, the thickness at described flexible cover body center is identical with the thickness of center.
Further, the thickness of described annular fillet is greater than the thickness of flexible cover body edge;
Further, described annular fillet is provided with multiple connecting hole for being connected with small-sized dentistry beveller housing.
The invention has the beneficial effects as follows: small-sized dentistry beveller compliant motion protective cover of the present invention, corrugationless and folding line under nature, easily make and regular maintenance cleaning, without distortion centrostigma during use, not fragile, service life is of a specified duration.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is the top view of Fig. 1.
Detailed description of the invention
Fig. 1 is structural representation of the present invention; Fig. 2 is the top view of Fig. 1, as shown in the figure: the small-sized dentistry beveller compliant motion protective cover of the present embodiment, comprise the center 1 at the center of being located at, be surrounded on the annular fillet 2 of center 1 outside and be connected between center 1 and annular fillet 2 and annular region between center 1 and annular fillet 2 forms the flexible cover body 3 of hood-like structure; Flexible cover body 3 is smooth surface, space fillet surface without folding line, corrugationless and folding line under nature, easy making and regular maintenance cleaning, without distortion centrostigma during use, not fragile, service life is of a specified duration, fixing on the main shaft that during installation, center 1 is enclosed within small-sized dentistry beveller, annular fillet 2 is fixed on the edge of the mouth of stepping down of corresponding main shaft on small-sized dentistry beveller housing, effectively protects main shaft drives parts.
In the present embodiment, the thickness of described flexible cover body 3 is thinning gradually to edge from center, makes the different piece of flexible cover body 3 have different deformation performances, therefore by flexible cover body 3 local elongation and can bend during motion of main shaft.
In the present embodiment, described center 1, flexible cover body 3 and annular fillet 2 are wholely set, and center 1, flexible cover body 3 are identical with the material of annular fillet 2, and easy machine-shaping can ensure sealing property.
In the present embodiment, described flexible cover body 3 is bowl structure, the rear end axially docking of the Center-to-Center cover 1 of flexible cover body 3, annular fillet 2 connects with the edge of flexible cover body 3, as shown in Figure 2, the center of flexible cover body 3 is to lordosis and connect with center 1, being surrounded on excentral part is curved in bowl until edge stretches to front side, and flexible cover body 3 connects with transition between center 1, easily shaping, and unstressed and distortion centrostigma, not fragile.
In the present embodiment, the thickness at described flexible cover body 3 center is identical with the thickness of center 1, easy processing and manufacturing, realize the excessively smooth of flexible cover body 3 and center 1 surface, in the present embodiment, the flexible thickness at cover body 3 center and the thickness of center 1 carry out reasonable set according to actual needs, to make flexible cover body 3 center and center 1 have certain anti-deformation, ensure center 1 and the stability be connected between main shaft.
In the present embodiment; the thickness of described annular fillet 2 is greater than the thickness of flexible cover body 3 edge; guarantee the structural strength of annular fillet 2, be beneficial to and process corresponding syndeton on annular fillet 2, improve the syndeton stability between itself and small-sized dentistry beveller housing.
In the present embodiment, described annular fillet 2 is provided with multiple connecting hole 4 for being connected with small-sized dentistry beveller housing, rational in infrastructure, is convenient to dismounting.
What finally illustrate is, above embodiment is only in order to illustrate technical scheme of the present invention and unrestricted, although with reference to preferred embodiment to invention has been detailed description, those of ordinary skill in the art is to be understood that, can modify to technical scheme of the present invention or equivalent replacement, and not departing from aim and the scope of technical solution of the present invention, it all should be encompassed in the middle of right of the present invention.
