The purpose of the utility model is completed by the following technical scheme: the novel dust cover structure with the movable end comprises a dust cover body, wherein one end of the dust cover body is a large end face of the dust cover, the other end of the dust cover body is a small end face of the dust cover, the large end face of the dust cover is used for being installed on a three-column groove shell in a matched mode, the small end face of the dust cover is used for being connected with an intermediate shaft, and the intermediate shaft is installed with the three-column groove shell in a matched mode through a tripod universal joint; the inner cavity of the dust cover body is provided with a mounting groove at a position close to the large end face of the dust cover, a special-shaped gasket is arranged in the mounting groove, the shape of the special-shaped gasket is consistent with that of the large end face of the three-column groove shell, and the inner cavity of the large end face of the dust cover is in rigid contact with the large end face of the three-column groove shell through the special-shaped gasket.
As a preferable technical scheme, a layer of rubber material the same as that of the dust cover body is coated on the surface of the special-shaped gasket.
As the preferred technical scheme, the inner diameter of the mounting groove is in interference fit with the outer diameter of the special-shaped gasket.
The utility model has the beneficial effects that: the special-shaped gasket coated with rubber is used in the mounting groove of the moving end dust cover, so that the inner end face of the moving end dust cover and the large end face of the three-column groove shell are changed into rigid contact with a buffering function from elastic contact, and the phenomenon that the tripod universal joint falls off from a roller way in the three-column groove shell is effectively prevented.

Description of reference numerals: the dustproof cover comprises a dustproof cover body 1, a dustproof cover large end face 1-1, a dustproof cover small end face 1-2, mounting grooves 1-3, a three-column groove shell 2, an intermediate shaft 3, a three-ball pin universal joint 4 and a special-shaped gasket 5.
Detailed Description
The utility model will be described in detail below with reference to the following drawings:
example (b): as shown in attached drawings 1-6, the novel movable end dust cover structure, referring to attached drawing 2, comprises a dust cover body 1, wherein one end of the dust cover body 1 is a large end face 1-1 of the dust cover, and the other end of the dust cover body 1 is a small end face 1-2 of the dust cover. The large end face 1-1 of the dust cover is used for being installed on the three-column groove shell 2 in a matched mode, the small end face 1-2 of the dust cover is used for being connected with the intermediate shaft 3, referring to fig. 6, one end of the intermediate shaft 3 is tightly matched with the small end face 1-2 of the dust cover, and the other end of the intermediate shaft 3 is installed with the three-column groove shell 2 in a matched mode after being sleeved with the tripod universal joint 4; the inner cavity of the dust cover body 1 is provided with a mounting groove 1-3 at a position close to the large end face 1-1 of the dust cover, a special-shaped gasket 5 is arranged in the mounting groove 1-3, as shown in fig. 4 and 5, the shape of the special-shaped gasket 5 is consistent with the shape of the large end face of the three-column groove shell 2 (is also consistent with the shape of the inner surface of the large end face 1-1 of the dust cover), and the inner cavity of the large end face 1-1 of the dust cover is in rigid contact with the large end face of the three-column groove shell 2 through the special-shaped gasket 5. Furthermore, a layer of rubber material which is the same as that of the dust cover body 1 is coated on the surface of the special-shaped gasket 5, so that a buffering function is provided for rigid contact between the large end face 1-1 of the dust cover and the large end face of the three-column groove shell 2, and the three-ball pin universal joint 4 is effectively prevented from falling off from a roller way in the three-column groove shell 2. The inner diameter of the mounting groove 1-3 is in interference fit with the outer diameter of the special-shaped gasket 5, so that the special-shaped gasket 5 can be effectively prevented from falling off.
The special-shaped gasket 5 is formed by stamping spring steel, has no sharp edges and burrs on the surface, is coated with the same rubber material as the dust cover body 1 after shot blasting treatment and phosphating treatment on the surface after heat treatment, quenching and tempering, and effectively protects the three-column groove shell 2 and the three-ball pin universal joint 4 which are in contact with each other, thereby providing a buffer effect for the contact of the three-column groove shell and the three-ball pin universal joint. Meanwhile, the existence of the special-shaped gasket 5 limits the axial movement of the tripod universal joint 4, and effectively prevents the tripod universal joint 4 from falling off from the ball path in the three-column groove shell 2 in the processes of transportation, installation and use, thereby prolonging the service life of the moving end dust cover. In addition, the inner diameter of the mounting groove 1-3 is in interference fit with the outer diameter of the special-shaped gasket 5, so that the special-shaped gasket 5 can be effectively prevented from falling off.
It should be understood that equivalent alterations and modifications of the technical solution and the inventive concept of the present invention by those skilled in the art should fall within the scope of the appended claims.
