[0011] Clearly, the described embodiments are merely a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all the other embodiments obtained by the ordinary skilled in the art without making creative labor belong to the scope of protection of the present utility model.

[0012] The utility model provides a kind of lower mounting structure of shock absorber as Figs. 1-3 As shown in a kind of lower mounting structure of shock absorber, including frame 101, shock absorber;

[0013] Specifically, the lower end of the frame 101 is provided with an ear 102, and the frame 101 is fixedly installed with a leaf spring 103 through the ear 102. The lower end of the shock absorber is fixedly connected with a shock absorber lower pin hole 106, and the lower end of the leaf spring 103 is fixedly connected with a leaf spring lower pin hole 105.

[0014] Specifically, the leaf spring lower pin hole 105 and the shock absorber lower pin hole 106 are sleeved with a hexagonal flange bolt 104, the other side of the hexagonal flange bolt 104 is provided with a nut 107, and the leaf spring lower pin hole 105 and the shock absorber lower pin hole 106 are fixedly connected through the hexagonal flange bolt 104 and the nut 107. Embodiment

[0015] The lower fixing structure of the traditional mounting structure shock absorber adopts a double-end pin shaft as a fixing piece, the double-end pin shaft is a machined part, and a double-end threaded structure is adopted, which has the following defects: 1. Low assembly efficiency: the current shock absorber lower pin shaft is fixed by nuts at both ends, and two tightening and torque setting operations are required to complete the assembly; 2. Low processing efficiency: the current shock absorber lower pin shaft process is as follows: 1) heat the middle large step first; 2) mill the middle flat position; 3) turn the two sides of the light pole; 4) turn the threads on both sides. The processing technology is complicated, and the cost is relatively high; after changing to a hexagonal flange bolt, the hexagonal flange bolt is a standard part, the cost is lower, and the installation is more simple than the traditional structure. The traditional installation fixes the double-end pin shaft between the leaf spring lower pin hole 105 and the shock absorber lower pin hole 106, and then sleeves the nuts on both ends, tightens and sets the torque on both sides. The device is installed: only the hexagonal flange bolt 104 is sleeved on the leaf spring lower pin hole 105 and the shock absorber lower pin hole 106, and the nut 107 is sleeved on one side, and then tightened and set the torque.

[0016] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and is not intended to limit the present application, although the foregoing embodiments of the present application has been described in detail, for the skilled in the art, it still can be modified, or for part of the technical features of the equivalent replacement, the spirit and principles of the present application, made any modification, equivalent replacement, improvement, etc., should be included within the scope of the present application.
