[0019] In the description of the utility model, it is necessary to explain that, unless another explicit provision and limitation, the term "installation", "connection", "connect" should be broad sense understanding, for example, can be fixed connection, also can be detachable connection, or integrally connected;Can be mechanical connection, also can be electrical connection;Can be directly connected, also can be indirectly connected through the intermediate medium, can be two elements inside the communication.For ordinary skilled in the art, the specific meaning of the above-mentioned terms in the utility model can be understood according to the specific circumstances.

[0020] Specific implementation is as follows:

[0021] As Figs. 1-3 The dustproof cover of the shock absorber includes cover body 1, the cover body 1 is provided with clamping part 2 and reinforced protection part 3.In the embodiment, the cover body 1, the clamping part 2 and the reinforced protection part 3 are integrally arranged.

[0022] Need to explain, the upper end of the shock absorber is provided with upper support seat 5, the upper end of the upper support seat 5 is provided with step part 51, the piston rod of the shock absorber is out of the center hole of the upper support seat 5, and the connecting block is arranged at the upper end of the center hole for connecting the dustproof cover.When the dustproof cover is connected with the upper support seat 5, the clamping part 2 is inserted into and clamped in the center hole of the connecting block, and the lower end of the reinforced protection part 3 abuts on the end face of the step part 51, so as to enclose the protection cavity 4 between the outer wall of the reinforced protection part 3, the cover body 1 and the step part 51.More specifically, a sealing ring is arranged at the connecting position of the reinforced protection part 3 and the step part 51, or sealing glue is applied, so as to ensure the sealing property of the connection between the reinforced protection part 3 and the step part 51 and enhance the resistance effect to liquid.

[0023] Further, the downward overhanging end of the reinforced protection part 3 is not higher than the opening end of the cover body 1, the opening end of the cover body 1 is larger than the step part 51, so that when the reinforced protection part 3 abuts on the end face of the step part 51, the lower end of the cover body 1 is covered on the upper support seat 5 and is lower than the upper end face of the step part 51, so as to ensure the protection degree of the connection between the clamping part 2 and the upper support seat 5 and improve the protection effect.

[0024] In the embodiment, the upper end of the step part 51 is provided with a slope, and the inner wall of the cover body 1 is in contact with the slope, so as to improve the tightness between the cover body 1 and the step part 51 and improve the protection effect.

[0025] Further, the cover body 1 is in the shape of a circular arc, so as to ensure that the liquid flows down smoothly from the circular arc-shaped cover body, and in combination with the cover body 1 covered outside the step part 51, the liquid flows down along the cover body 1 and flows away along the upper support seat 5, so as to reduce the splashing of liquid.

[0026] Further, to ensure the firmness of the connection between the clamping part 2 and the upper support seat 5, a clamping groove 21 is arranged annularly on the outer wall of the clamping part 2 near the lower end.

[0027] Further, a plurality of vertical slits 22 are arranged circumferentially on the lower end of the clamping part 2, so as to ensure that the lower end of the clamping part 2 has a certain deformation amount, facilitating the installation and dismounting process between the clamping part 2 and the upper support seat 5, and improving the convenience of use.

[0028] In use, the clamping part 2 extends into the central hole of the connecting block connected to the upper support seat 5, and the clamping groove 21 ensures the firmness of the clamping part 2. The slits 22 on the clamping part 2 make the end portion have a certain deformation amount, facilitating the installation and dismounting between the clamping part 2 and the connecting block. After the clamping part 2 is connected to the upper support seat 5, the lower end of the reinforcing protection part 3 abuts against the upper end of the stepped part 51, the lower end of the cover body 1 is covered outside the stepped part 51, and the cover body 1 and the stepped part 51 are in inclined surface contact, so that the inner wall of the cover body 51, the outer wall of the reinforcing protection part 3 and the upper end of the stepped part 51 enclose the protection cavity 4, the space between the reinforcing protection part 3 and the clamping part 2 is isolated, and when liquid splashes from bottom to top, it first enters the protection cavity 4, the protection cavity 4 forms a second waterproof buffer area, effectively preventing the splashing liquid from directly entering the inner cavity, thereby achieving effective dustproof and waterproof effect.

[0029] The utility model has been described exemplarily above in combination with the drawings, and obviously, the specific implementation of the utility model is not limited by the above-mentioned mode, as long as various non-essential improvements are made by adopting the technical scheme of the utility model, or the concept and technical scheme of the utility model are directly applied to other occasions without improvement, all of which are within the protection scope of the utility model.
