Description

The automobile glass lifter bearing of reaching the standard grade

Technical field

The utility model relates to a kind of automobile glass lifter bearing of reaching the standard grade, and relates to a kind of seat structure of reaching the standard grade that is used on the line formula automobile glass lifter particularly.

Background technology

Automobile glass lifter is used for the lifting of glass.Can be divided into line formula and arm-type by operating structure.As shown in Figure 1, line formula automobile glass lifter mainly is made of parts such as lifter motor 10, line wheel 12, coiling 20, guide rail 13 and supporting plates 23.The bearing of reaching the standard grade is installed on the upper end of guide rail, and coiling is connected with supporting plate through the bearing of reaching the standard grade.In the time will opening glass, press the glass lifting button, the lifter electric motor starting drives the line wheel rotation that links to each other with electric machine rotational axis, and the online wheel outer surface above-below direction that winds the line twines.When coiling is twined, and then rotation of the pulley on the bearing of reaching the standard grade of guide rail upper end, the supporting plate fixing with coiling moves on guide rail, drives the glass lifting that is connected with supporting plate.Existingly reach the standard grade bearing as shown in Figure 2, the body 600 of the bearing of reaching the standard grade is the circle shape, and a side prolongs outstanding, plastic material, injection mo(u)lding.Its structure central portion has combined hole, prolongs the sleeve pipe installation position 620 that the helpful coiling of protuberance is moved, and has Baltimore groove to be used to install pulley 630, the sleeve pipe 640 that helpful coiling is moved.The bearing of reaching the standard grade of this structure, sleeve pipe is inserted in the sleeve pipe installation position, and there is coiling the sleeve pipe the inside.Twine through the degree of tightness that winds the line repeatedly, the sleeve pipe of this structure can and produce be full of cracks to a direction bending, causes coiling to rupture.This kind structure bearing of reaching the standard grade rotates easily in addition.

Summary of the invention

In order to address the above problem, the utility model provides not easy fracture of a kind of coiling, and service time is long, the non-rotary automobile glass lifter of the bearing of the reaching the standard grade bearing of reaching the standard grade.

To achieve these goals, the technical solution adopted in the utility model is: a kind of automobile glass lifter bearing of reaching the standard grade, comprise body, pulley and connector, it is characterized in that main body structure is: the center is provided with the combined hole of perforation, the outside forms the meander-shaped that can encircle coiling by first zigzag part on top and second zigzag part of bottom, first zigzag part and second zigzag part form the corresponding fixing hole of diameter with connector in the position that a side of body is met, opposite side at the body opposite with fixing hole forms the peristome that coiling can be passed through, and is provided with the hook position on the body of peristome one side; Connector is made of insertion section and epitaxy part,, and connector and body is linked together in fixing hole inserts body by the insertion section; Pulley is connected with body by rivet pin in the inside of body.

The beneficial effects of the utility model are: the utility model utilizes the projection in flange hole owing to be provided with the hook position on a seat body of reaching the standard grade, and combines with guide rail hole, and the bearing that prevented to reach the standard grade rotates along with the rotation of pulley.Adopt in addition retractility preferably material make connector, prevent coiling fracture.

The specific embodiment

As Fig. 3～shown in Figure 6, a kind of automobile glass lifter bearing of reaching the standard grade comprises body 60, pulley 70 and connector 67.

Body 60 is circular substantially, one epitaxial lateral overgrowth is stretched outstanding, the center of body 60 is provided with the combined hole 61 of perforation, the outside forms the meander-shaped that can encircle coiling by first zigzag part 62 on top and second zigzag part 63 of bottom, in the body 60 outstanding side that stretches out, on the position of the discontinuity surface that first zigzag part 62 and second zigzag part 63 meet, form the corresponding fixing hole 64 of diameter with connector 67, opposite side at the body 60 opposite with fixing hole 64 forms the peristome 65 that coiling can be passed through, and is provided with hook position 66 on the body 60 of peristome 65 1 sides; Connector 67 is made of insertion section 68 and epitaxy part 69, is inserted in the body 60 through fixing hole 64 by insertion section 68, and connector 67 and body 60 are linked together; Pulley 70 is connected with body 60 by rivet pin 71 in the inside of body 60.

As shown in Figure 6, the hook position is the flange hole.
