Technical Field

[0001] The utility model relates to the technical field of shock absorber compression valve seats, in particular to an impact-resistant shock absorber compression valve seat. Background Art

[0002] A car is a power-driven, non-track-borne vehicle with four or more wheels. It is mainly used for: carrying people and goods; towing vehicles carrying people and goods; and special purposes. When the car is running, it will produce bumps. In order to improve the driving experience of the car, shock absorbers and compression valve seats are needed to cooperate for shock absorption to improve the driving experience of the car.

[0003] At present, most of the shock absorber compression valve seats on the market use internal buffer springs and buffer blocks to offset the impact force on the compression valve seats, thereby improving the impact resistance of the compression valve seats. For example, a shock absorber compression valve seat for automobiles disclosed in Chinese patent publication No. CN219655151U, but the buffer springs and buffer blocks located in the compression valve seat are more troublesome to disassemble and assemble, which makes it more troublesome to replace damaged buffer springs and buffer blocks.

[0008] Preferably, the locking bracket includes a bearing surface fixedly connected to the inner wall of the groove, the inner wall of the bearing and the inner wall of the circular plate are both fixedly connected with a second cylinder, the surface of the second cylinder contacts the inner wall of the first cylinder, a second hollow column is fitted on the inner wall of the second cylinder, a return spring is fixedly connected to the upper surface of the second hollow column, the upper surface of the return spring contacts the inner wall of the groove, a strip column is fixedly connected to the surface of the second hollow column, a sliding groove is provided on the upper surface of the second cylinder, the inner wall of the sliding groove and the inner wall of the positioning groove are both in contact with the surface of the strip column, and a rotating block is fixedly connected to the surface of the second hollow column.

[0009] Preferably, a first connecting column is fixedly connected to the bottom of the valve seat body, a mounting ring is fixedly connected to the bottom of the first connecting column, and a shock-absorbing base is fixedly connected to the bottom of the mounting ring.

Then, the user can intuitively judge whether the buffer spring needs to be replaced by feeling the size of the resistance encountered when rotating the circular ring, which makes it more convenient for the user to repair the buffer spring.
