The maximum thickness of the buffer body is less than the width of the opening below the track. The buffer body is located between the first and second pulley groups. One end of the buffer body is detachably hooked to the first pulley group, and the buffer body is rotatably mounted relative to the first pulley group. The other end of the buffer body is detachably fastened to the second pulley group. This is achieved by detachably hooking one end of the buffer body to the first pulley group and detachably fastening the other end of the buffer body to the second pulley group.
[0003] In the existing technology, elastic snap-fit pulley blocks are used to achieve quick connection. Although this solves the problem of installation efficiency, the connection stability is lacking and needs further improvement. Utility Model Content

[0031] See Figures 1-6 An easy-to-install shock absorber includes a shock absorber body 10 and a wheel set 20. The wheel set 20 includes at least a wheel seat 210. The wheel seat 210 has an installation socket 220. The shock absorber body 10 is provided with an installation plug 110. The installation plug 110 is movably inserted into the installation socket 220 in a first direction.
[0032] The outer surface of the mounting plug 110 is provided with an annular locking groove 120, and the wheel seat 210 is provided with a plurality of mounting holes 230 arranged in a circular array along the circumference, and the mounting holes 230 are provided with spring pin modules 30.
[0033] A drive ring 40 is rotatably provided on the outer wall of the wheel seat 210; an avoidance groove 410 corresponding to the spring pin module 30 is provided on the inner wall of the drive ring 40.
[0034] When the spring pin module 30 corresponds to the clearance groove 410, the spring pin module 30 disengages from the annular locking groove 120 and moves into the clearance groove 410.
[0035] When the spring pin module 30 and the clearance groove 410 are misaligned, the inner wall of the drive ring 40 fits against the spring pin module 30 to drive the spring pin module 30 into the annular locking groove 120, thereby constraining the wheel seat 210 to move relative to the mounting plug 110.
[0036] During assembly, the drive ring 40 is rotated to align the spring pin module 30 with the clearance groove 410, and then the mounting plug 110 is movably inserted into the mounting socket 220 along the first direction. Finally, the drive ring 40 is rotated to misalign the spring pin module 30 with the clearance groove 410. In this state, the spring pin module 30 is pressed by the inner wall of the drive ring 40, and the spring pin module 30 is inserted into the annular locking groove 120 to constrain the movement of the wheel seat 210 relative to the mounting plug 110.
[0037] See Figure 3 and Figure 5 The drive ring 40 is provided with a locking ring 50, which is connected to a first toothed ring 710. The wheel seat 210 is provided with a second toothed ring 720. The locking ring 50 is movable relative to the drive ring 40 in a first direction, moving between a first position and a second position. When the locking ring 50 is in the first position, the first toothed ring 710 and the second toothed ring 720 mesh with each other to constrain the drive ring 40 from rotating relative to the wheel seat 210. When the locking ring 50 is in the second position, the first toothed ring 710 and the second toothed ring 720 are separated. In this embodiment, the drive ring 40 and the locking ring 50 are configured to rotate synchronously, that is, when the drive ring 40 rotates, the locking ring 50 will rotate synchronously. When the locking ring 50 cannot rotate, the drive ring 40 also cannot rotate. Under the meshing action of the two toothed rings, the drive ring 40 is locked, preventing it from rotating arbitrarily and improving the locking stability of the elastic module 30. Before rotating the drive ring 40, the locking ring 50 needs to be moved to the second position to separate the two gear rings. In this state, the drive ring 40 can rotate relative to the wheel seat 210.
[0038] See Figure 3 and Figure 5 A first spring 60 is provided between the locking ring 50 and the driving ring 40; the first spring 60 is used to apply force to the locking ring 50 to keep it in a first position. When unlocking, the locking ring 50 is driven to move to a second position, during which the first spring 60 is compressed and stores force.
[0039] See Figure 3 The spring pin module 30 includes a locking pin 310 that is movable relative to the mounting hole 230. A limit nut 320 is connected to one end of the mounting hole 230 away from the annular locking groove 120. A second spring 330 is connected to the mounting hole 230 and the locking pin 310. The second spring 330 is used to apply a force to the locking pin 310 so that the locking pin 310 moves away from the annular locking groove 120.
[0040] Furthermore, the locking pin 310 is provided with a connecting plate 340, and the second spring 330 is sleeved on the locking pin 310 and located between the connecting plate 340 and the wall of the mounting hole 230.
[0041] See Figure 3 The wheel seat 210 is provided with an annular limiting groove 240, the drive ring 40 is provided with a threaded hole 400 corresponding to the annular limiting groove 240, and the locking ring 50 is provided with a moving guide groove 510 corresponding to the threaded hole 400. A guide bolt 80 passes through the moving guide groove 510; the guide bolt 80 is threadedly connected to the threaded hole 400 and extends into the annular limiting groove 240. In this embodiment, the guide bolt 80 restricts the drive ring 40 to rotate only relative to the wheel seat 210, while restricting the locking ring 50 to move relative to the drive ring 40.
[0042] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
