the sliding mechanism 7 comprises a sliding rail 701, a sliding groove 704 is formed in the inner wall of the sliding rail 701, a sliding block 702 is connected to the inner wall of the sliding groove 704 in a sliding mode, a connecting spring 703 is fixedly connected to the surface of the sliding block 702, and one side, far away from the sliding block 702, of the connecting spring 703 is fixedly connected with the upright post 5.

In this embodiment: the upper shell 2 and the lower shell 3 are matched to block most of impurities which can be contacted with the shock absorber body 1, the shock absorber body 1 is compressed and reset to a certain degree to achieve a shock absorption effect when a vehicle bumps and shakes, at the moment, the upright post 5 connected with the outer wall of the lower shell 3 through the support frame 12 moves up and down in the sleeve post 6, so that the position between the upper shell 2 and the lower shell 3 can move along with the shock absorber body 1, when the shock absorber body 1 generates torque, the upright post 5 moves in the sliding groove 704 of the sliding rail 701 through the connecting spring 703 and the sliding block 702, the connecting spring 703 generates certain bending and generates bending moment along with the shock absorber body 1, the problem that the rigid connection between the upper shell 2 and the lower shell 3 cannot generate bending to cause damage is avoided, and the risk of self twisting in the case of protecting the shock absorber body 1 like a flexible material is avoided, moreover, the upper shell 2 and the lower shell 3 are made of rigid materials, so that the shock absorber is not easy to damage, and the shock absorber body 1 can be protected.

As the utility model discloses a technical optimization scheme, the top fixedly connected with spliced pole 4 of 1 outer wall of bumper shock absorber body, the outer wall and the 2 fixed connection of epitheca of spliced pole 4.

In this embodiment: through setting up spliced pole 4, connect epitheca 2 and bumper shock absorber body 1, when connecting it, for prop up certain distance between epitheca 2 and the bumper shock absorber body 1 to the inboard structure of epitheca 2 is installed.

As the technical optimization scheme of the utility model, the quantity of cover post 6 and stand 5 is four, and the top fixedly connected with stopper 8 of 6 inner walls of cover post.

In this embodiment: through setting up a plurality of cover posts 6 and stand 5, can increase the connection between upper casing 2 and the inferior valve 3 for the structure is more stable.

As the technical optimization scheme of the utility model, dead slot 9 has been seted up to the outer wall of stand 5, and the fixed surface of sliding block 702 is connected with gag lever post 10, and gag lever post 10 sets up in coupling spring 703's inner wall, and one side that sliding block 702 was kept away from to gag lever post 10 sets up in the inboard of dead slot 9.

In this embodiment: through setting up gag lever post 10, inject connecting spring 703, avoid it because too big unable self-righting that causes of moment of flexure that produces, can increase the connection between sliding block 702 and the stand 5 moreover.

As the utility model discloses a technical optimization scheme, the bottom fixedly connected with anticreep piece 11 of spout 704 inner wall, anticreep piece 11 uses with the sliding block 702 cooperation.

In this embodiment: through setting up anticreep piece 11, seal the processing to the bottom of spout 704, the effectual movable position who restricts sliding block 702 avoids its effect of not being convenient for reinstallate because the too big roll-off of follow spout 704 bottom roll-off that causes of activity range.

As the technical optimization scheme of the utility model, the bottom fixedly connected with net section of thick bamboo 13 of 2 outer walls of epitheca, net section of thick bamboo 13 set up in the outside of inferior valve 3.

In this embodiment: through setting up a net section of thick bamboo 13, protect the space between epitheca 2 and inferior valve 3, avoid having impurity to result in being blocked the crack department of bumper shock absorber body 1 from the inside contact with bumper shock absorber body 1 of space access device between epitheca 2 and inferior valve 3.

The working principle is as follows: firstly, the shock absorber body 1 is installed on a motor vehicle, on a road surface with more gravels, the upper shell 2, the lower shell 3 and the net barrel 13 can prevent gravels and branches and the like from being clamped into the spring on the outer side of the shock absorber body 1, when the shock absorber body 1 needs to work for a long time to stabilize the vehicle on a bumpy road surface, when the shock absorber body 1 moves longitudinally, the upright post 5 connected with the outer side of the lower shell 3 through the support frame 12 is contacted and connected with the slide rail 701 in the sleeve post 6 through the connecting spring 703, so that the upper shell 2 and the lower shell 3 also move longitudinally when the shock absorber body 1 moves, because the anti-falling block 11 is arranged at the bottom of the slide groove 704 on the inner side of the slide rail 701, the sliding block 702 can not fall from the bottom of the anti-falling block 11, the limit block 8 arranged at the top of the sliding block 702 limits the limit position at the top of the sliding block 702, when a bending moment is generated, the connecting spring 703 produces the moment of flexure, and the stand 5 produces certain slope in the inside of socle 6, avoids the stand 5 that rigid connection leads to be broken, sets up the gag lever post 10 in the inside dead slot 9 can avoid the connecting spring 703 because the too big condition emergence that leads to of the moment of flexure of self production can not reset by oneself.

The above description is only exemplary of the present invention and should not be construed as limiting the present invention, and any modifications, equivalents and improvements made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
