Description
Technical Field
The utility model relates to a field of dust cover, concretely relates to piston dust cover structure.
Background
The existing piston dust cover is in single-side interference contact with the piston. When the piston dust cover is assembled, the inner ring of the dust cover assembly needs to be buckled into the groove of the piston. The prior art scheme mainly has the following defects: only one side of the groove of the dust cover piston is used, and two side surfaces do not play a sealing role; after the piston is installed in place, gaps are still formed in the left side and the right side of the piston of the dust cover, and the piston and the dust cover can have certain displacement, so that the sealing effect is influenced.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to overcome the not enough of prior art existence, and provide a piston dust hood structure.
The purpose of the utility model is accomplished through following technical scheme: this kind of piston dust hood structure, mainly include the dust cover, a piston, a main part, the sealing, functional surface A, functional surface B, the seal groove, functional surface A, functional surface B, the design of the main part tip of dust cover has the sealing, the sealing left and right sides is functional surface A respectively, functional surface B, the design has the seal groove on the piston tip external diameter, the seal groove left and right sides is functional surface A respectively, functional surface B, the sealing is installed in the seal groove, functional surface A, functional surface B respectively with functional surface A, functional surface B pastes tight seal.
The sealing part and the sealing groove adopt a wedge-shaped assembly structure.
The functional matching surface A and the functional surface A are designed as installation inlets, and the angle alpha of the functional matching surface A and the functional surface A is 50 degrees.
The functional matching surface B and the functional surface B are designed as outlets, and the angle beta of the functional matching surface B and the functional surface B is 60 degrees.
The utility model has the advantages that: the utility model changes the assembly form of the piston dust cover and increases the number of the functional surfaces of the piston seal; the wedge-shaped seal is adopted, the sealing effect is optimized, the piston groove structure completely conforms to the structure for assembling the piston dust cover, the relative displacement of the piston dust cover and the piston is limited, the piston dust cover and the piston do not have relative displacement, and the sealing effect is further ensured; the calipers are guaranteed to be completely sealed when being loaded and used, and the waterproof and dustproof effects are remarkable.

Detailed Description
The present invention will be described in detail with reference to the accompanying drawings:
example (b): as shown in the accompanying drawings, the piston dust-proof cover structure mainly comprises a dust cover 1, a piston 2, a main body 3, a sealing part 4, a functional surface A5, a functional surface B6, a sealing groove 7, a functional matching surface A8 and a functional matching surface B9, the end part of the main body 3 of the dust cover 1 is designed with the sealing part 4, the left side and the right side of the sealing part 4 are respectively the functional surface A5 and the functional surface B6, a sealing groove 7 is designed on the outer diameter of the end part of the piston 2, the left side and the right side of the sealing groove 7 are respectively the functional matching surface A8 and the functional matching surface B9, the sealing part 4 is installed in the sealing groove 7, and the sealing part 4 and the sealing groove 7 adopt a wedge-shaped assembly structure. The functional matching surface A8 and the functional matching surface B9 are respectively tightly sealed with the functional surface A5 and the functional surface B6. The functional matching surface A8 and the functional surface A5 are designed as installation inlets, the angle alpha of the functional matching surface A8 and the functional surface A5 is 50 degrees, and the piston assembly is convenient. The functional matching surface B9 and the functional surface B6 are designed to be outlets, the angle beta of the functional matching surface B9 and the functional surface B6 is 60 degrees, the length of a contact surface is increased, and the sealing effect is effectively guaranteed.
It should be understood that equivalent substitutions or changes to the technical solution and the inventive concept of the present invention should be considered to fall within the scope of the appended claims for the skilled person.
