[0026] As Figures 1-6The quick detachable shock absorber bracket shown, comprising an integral injection molded bracket body 1, the main part of the bracket body 1 is a bent cantilever 101, the bending of the cantilever 101 is to adapt to the mounting space reserved for other components around the shock absorber, both ends of the cantilever 101 are fixedly connected with shaft sleeves 103, the sizes of the two shaft sleeves 103 can be different, but the axes need to be parallel, the inner side of the cantilever 101 is fixedly connected with the outer side of the two shaft sleeves 103, the thickness of the rib plate 102 is smaller than that of the cantilever 101, but it can effectively improve the bending resistance of the cantilever 101, one end of each shaft sleeve 103 has a limiting disc 104, the end face of the limiting disc 104 has a center shaft 105 inside the shaft sleeve 103, the center shaft 105 is long enough to extend out of the shaft sleeve 103, in fact, the limiting discs 104 on the two shaft sleeves 103 are located at the same end, which is more convenient for disassembly and assembly, the center shaft 105 is coaxial with the limiting disc 104, and an annular cavity is formed between the outer side of the center shaft 105 and the inner wall of the limiting disc 104, which is used to cooperate with the corresponding matching structure on the outer side of the shock absorber shell, which requires the diameter of the center shaft 105 to be smaller than the inner diameter of the shaft sleeve 103, and in general, the diameter of the center shaft 105 is controlled to be one half to five thirds of the inner diameter of the shaft sleeve 103.

[0027] The center shaft 105 is sleeved with a rotation stop ring 2 outside the shaft sleeve 103, which is used to prevent the matching structure on the outer side of the shock absorber shell from being separated from the end of the center shaft 105, a through hole 201 is formed in the center of the rotation stop ring 2, which is used to be inserted with the end of the center shaft 105, and a flat head groove 106 is formed on the outer side of the end of the center shaft 105, the inner wall of the through hole 201 has a matching surface 202, after the flat head groove 106 is matched, the rotation stop ring 2 cannot rotate relative to the center shaft 105, the rotation stop ring 2 is usually made of nylon material, and the surface has good oil slip property, so it can smoothly rotate relative to the matching structure on the outer side of the shell without coating lubricating oil.

[0028] The end of the central shaft 105 is also inserted with a spring pin 3, which is actually a common O-shaped safety pin. The limiting disc 104 is located between the shaft sleeve 103 and the spring pin 3, which can prevent the limiting disc 104 from being separated from the end of the central shaft 105. In the embodiment, the flat head groove 106 at the end of the central shaft 105 has two symmetrical and parallel flat head grooves 106. The central shaft 105 is provided with a pin hole 107 penetrating the two flat head grooves 106 for the spring pin 3 to pass through. The specific structure of the spring pin 3 includes a pin shaft 301, only the pin shaft 301 needs to pass through the pin hole 107. One end of the pin shaft 301 has an end handle 302, and the side surface of the other end is provided with a let-in groove 304. The end handle 302 is rotationally connected with a limiting snap 303. The two ends of the limiting snap 303 connected with the end handle 302 are staggered, so that there are two self-locking limit positions when rotating. The limiting snap 303 can bypass the end of the central shaft 105 and be pressed in the let-in groove 304, so that the pin shaft 301 cannot be separated from the pin hole 107.

[0029] Working principle: The shock absorber support is mainly used for installation on a toy car. When installing, first make the two central shafts 105 respectively inserted with the cooperating structure on the outer side of the shock absorber and the cooperating structure on the bottom of the frame. The cooperating structure is embedded in the cavity formed between the central shaft 105 and the shaft sleeve 103. Then, the two rotation stopping rings 2 are respectively sleeved on the ends of the central shaft 105, and the pin shaft 301 of the opened spring pin 3 is inserted through the pin hole 107. Finally, rotate the limiting snap 303 to cooperate with the let-in groove 304. In this way, the shock absorber can be stably connected with the frame through the support. When disassembling, first remove the spring pin 3, then hold the cantilever 101 and the rib plate 102 part, and shake and pull in the direction away from the rotation stopping ring 2. The two central shafts 105 can be separated from the corresponding shock absorber cooperating structure and the frame cooperating structure, without the need of tools, and the disassembly and assembly operation can be quickly completed.
