Detailed description of the invention
For making the purpose of this utility model, technical scheme and advantage clearly, below in conjunction with the accompanying drawings and the specific embodiments the utility model is described in detail.
The utility model embodiment provides a kind of front sliding column shock absorber disassembly and assembly structure, as shown in Figure 2, Figure 3 and Figure 4, comprise: for the sleeve 1 of the fastening nut 6 on dismounting shock absorber piston rod 8, for clamping the first spanner 2 of described sleeve 1 and the second spanner 3 for fixing described shock absorber piston rod 8, wherein
As shown in Figure 5, be tube-in-tube structure schematic diagram of the prior art.In the prior art, the outer shape of sleeve is cylinder, outer shape because of sleeve is not suitable for spanner clamping, therefore, a square opening is offered at the middle part of sleeve upper end, for the driving end of spanner is inserted wherein, the rotation of sleeve is realized again by operation brace arm, but the sleeve of this structure and spanner, when dismounting front sliding column shock absorber, cannot be fixed shock absorber piston rod, thus be difficult to the dismounting realizing shock absorber, in order to overcome this shortcoming, the utility model embodiment provides tube-in-tube structure as shown in Figure 6, wherein
Described sleeve 1 is hollow columnar structures, described sleeve 1 comprises: clamping part 4 and fastening nut dismounting portion 5, described first spanner 2 is clamped and connected with described clamping part 4, the mating shapes that the outer shape of described clamping part 4 and described first spanner 2 clamp, hexagon can be designed to, quadrangle, the shape of the suitable clampings such as ellipse, by the outer shape of sleeve 1 being improved to the shape of suitable spanner clamping, not only remain the using method in Fig. 1, the driving end of spanner is also made the external belt moving sleeve 1 of direct gripper sleeve 1 to rotate, recycle the middle part of another spanner through sleeve 1, fixed buffer piston rod 8, thus achieve the dismounting of shock absorber 9.
Described fastening nut dismounting portion 5 is connected with described fastening nut 6, the described interior shape in fastening nut dismounting portion 5 and the mating shapes of described fastening nut 6, generally, fastening nut 6 is outer-hexagonal structure, therefore, the interior shape in fastening nut dismounting portion 5 can be designed to hexagon;
