Description
Technical Field
The utility model relates to an accessory of high-speed railway shock absorber, in particular to detachable shock absorber dust cover.
Background
Under the background of rapid development of a Chinese high-speed train, the high-speed rail shock absorber can improve the comfort when passengers sit on the high-speed rail, and due to the functional characteristics and the maintainability of the high-speed rail shock absorber, the abrasion of parts in the shock absorber is continuously increased when the train runs, and the shock absorber needs to be maintained after a certain operating mileage is reached.
At present, the domestic dust cover of the shock absorber is welded with a dust cover connecting sleeve through a dust cover, and the dust cover is fixed on the dust cover connecting sleeve through threaded connection. The dust cover and the dust cover connecting sleeve can be fixed only by welding. The process has the advantages of high cost, environmental protection, and difficulty in saving cost, and influences the regular maintenance of the shock absorber, thereby bringing inconvenience to maintenance personnel.
Disclosure of Invention
In order to solve the problem of the prior art, the utility model provides a detachable shock absorber dust cover, it is through dust cover one-time stamping forming, fixes the dust cover on the dust cover through threaded connection's form, has reduced welding process, environmental protection, saving cost.
The utility model discloses the technical scheme who adopts as follows:
the utility model provides a detachable shock absorber dust cover, includes the dust cover lid, dust cover lid top welding have rings, dust cover lid top center be provided with the screw hole, the screw hole in the spiro union piston pole, the below spiro union of dust cover lid have the dust cover.
Preferably, the inner side wall of the outer ring of the dust cover is provided with an internal thread, the upper part of the outer wall of the dust cover is provided with an external thread, and the dust cover are in threaded connection with each other through the internal thread and the external thread.
Preferably, the dustproof cover cap is formed by one-time stamping, a concave part is arranged at the top of the dustproof cover cap, and the threaded hole is formed in the concave part.
The utility model provides a beneficial effect that technical scheme brought is:
the utility model solves the problem that the connecting sleeve of the dust cover and the dust cover needs to be welded and fixed with extremely low cost on the basis of the existing dust cover; the existing dust cover is directly changed into one-step punch forming, the welding procedure of the dust cover and the dust cover connecting sleeve is omitted, the operation difficulty and the cost are reduced, the problem of environmental pollution is solved, and the dust cover is connected with the dust cover through threads, so that the dust cover is convenient to repair and disassemble.
