Abstract
The utility model discloses an automatic adjustment arm with dustproof construction, including the casing, set up the worm and worm wheel in the casing, its characterized in that, the one end that the worm stretches out the casing outer is established to hexagonal head structure, in hexagonal head structure department is equipped with a shield, the shield with the casing connection that cooperatees, shield one side is equipped with protrudingly, swell for hollow cavity structures. The utility model belongs to the technical field of automobile parts, a simple structure and can prevent effectively that the filth from getting into the automatic adjustment arm in the worm hole is provided, improved the life who adjusts the arm.
Description
Technical field
The utility model belongs to technical field of automobile parts, is specifically related to a kind of automatic adjusting arm with dustproof construction.
Background technique
Braking adjusting-arm is the important composition parts of motor vehicle braking system, and the adjustment arm in prior art is usually assembled by parts such as housing, worm screw, worm pin and linings and formed.Then above-mentioned braking adjusting-arm is not owing to having sealing configuration between worm screw and housing, is easy in use infiltrate dust, silt, thus the part easily worn and torn in housing, greatly reduce the working life of product.The dust proof member that prior art is heavy, complex structure, sealing is inadequate, but therefore necessity provides a kind of automatic adjusting arm with good dust-proof sealing structure.
Model utility content
The purpose of this utility model is to provide a kind of structure simple and can effectively prevents dirt from entering automatic adjusting arm in worm hole, improves the working life of adjustment arm.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of automatic adjusting arm with dustproof construction, comprise housing, the worm and worm wheel be arranged in housing, described worm screw one end of stretching out outside housing is set to six square head structures, a dust cover is provided with in described six square head structure places, described dust cover and described housing in mating connection, described dust cover side is provided with projection, and described projection is hollow cavity structure.
Preferably, in order to prevent dust cover from coming off, the flange of Drop-proof is provided with at the outer wall of described projection.
Preferably, in order to play sealing and dustproof effect better, the vertical section of described hollow cavity structure is tapered.
Preferably, in order to reach good sealing effect, between described worm screw and described housing, a seal ring is provided with.
Compared with prior art, the beneficial effects of the utility model are:
The utility model structure is simple, in worm screw one end of automatic adjusting arm, dust cover is set, can effectively prevent dust dirt etc. from polluting worm screw, improve the working life of worm screw, be provided with the flange of Drop-proof at the projection outer wall of dust cover simultaneously, improve the fastness of dust cover, make it can not come off in running.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation with the automatic adjusting arm of dustproof construction of the utility model;
Fig. 2 is the schematic enlarged-scale view of the utility model dust cover.
In figure, 1, housing, 2, worm screw, 3, worm gear, 4, six square head structures, 5, dust cover, 501, projection, 502, hollow cavity structure, 503, flange, 6, seal ring.
Embodiment
In order to make the purpose of this utility model, technological scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
Consult shown in Fig. 1 and Fig. 2, a kind of automatic adjusting arm with dustproof construction, comprise housing 1, be arranged at worm screw 2 in housing 1 and worm gear 3, described worm screw 2 one end of stretching out outside housing is set to six square head structures 4, a dust cover 5 is provided with in described six square head structure 4 places, described dust cover 5 is in mating connection with described housing 1, and described dust cover 5 side is provided with projection 501, and described projection 501 is hollow cavity structure 502.
Preferably, in order to prevent dust cover 5 from coming off, the flange 503 of Drop-proof is provided with at the outer wall of described projection 501.
Preferably, in order to play sealing and dustproof effect better, the vertical section of described hollow cavity structure 502 is tapered.
Preferably, in order to reach good sealing effect, between described worm screw 2 and described housing 1, be provided with a seal ring 6.
The above embodiments are only preferred embodiment of the present utility model, can not limit interest field of the present utility model with this, and therefore, the equivalent variations done according to the utility model claim, still belongs to the scope that the utility model is contained.
