[0019] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0020] See also Figure 1 and Figure 3 A spring protection structure for a shock absorber comprises a spring shock absorber 1, a connection seat 2 is fixedly connected to the inner bottom of the spring shock absorber 1, a connection sleeve 3 is provided on the outer sleeve of the connection seat 2, a protection structure body 4 for protecting the spring is fixedly connected to the top of the connection sleeve 3, and a clamping block 5 is fixedly connected to the top of the protection structure body 4;

[0021] Two locking assemblies are arranged on both sides of the outer surface of the spring shock absorber 1 near the top, and the two locking assemblies both include a shell 6, and the two shells 6 are respectively fixedly connected to the two sides of the surface of the spring shock absorber 1, and a pin rod 7 is arranged on one side of the surface of the two shells 6, and one end of the pin rod 7 slides through and extends to the interior of the shell 6 and is fixedly connected with a clamp 8, and one end of the clamp 8 slides through and extends to the interior of the spring shock absorber 1, and a return spring 9 is sleeved on the outside of the pin rod 7, and one end of the return spring 9 is fixedly connected to the inner wall of the shell 6, and the other end of the return spring 9 is fixedly connected to one side of the surface of the clamp 8.

[0022] like Figures 1 to 3 As shown, the end of the pin rod 7 away from the shell 6 is fixedly connected with a pull ring 701, which is convenient for pulling the pin rod 7. The top of the block 5 is fixedly connected with an elastic pad 501, and the elastic pad 501 is made of sponge material. When the block 5 is moved upward to squeeze the elastic pad 501, the top of the elastic pad 501 is pressed against the inner top of the spring shock absorber 1, and the elastic pad 501 can prevent dust and debris from entering the protective structure body 4. The telescopic sleeve 401 is made of rubber material, has good elasticity, and is convenient for compression and stretching. The protective structure body 4 includes the telescopic sleeve 401. The inner wall of the telescopic sleeve 401 is fixedly connected with multiple support rings 402, and the multiple support rings 402 are equidistantly distributed. The support rings 402 can support the telescopic sleeve 401. The top of the block 5 and the bottom of the clamping head 8 are chamfered. The top of the clamping head 8 is slidably connected to the bottom of the block 5, and the bottom of the block 5 is tightly pressed against the top of the clamping head 8. When the block 5 moves upward, the chamfered surface of the block 5 slides over the chamfered surface of the clamping head 8, and the bottom of the block 5 is tightly pressed against the top of the clamping head 8, so the block 5 can be fixed.

[0023] When the utility model is in use, the card block 5 is first pressed downward to shrink and fold the protective structure body 4 together, and then the connecting sleeve 3 is threadedly installed on the outside of the connecting seat 2. After the connecting sleeve 3 is fixed, the card block 5 is dragged upward to unfold the protective structure body 4 and cover the spring in the spring shock absorber 1. The card block 5 squeezes the clamping head 8, and the clamping head 8 slides toward the inside of the shell 6 so that the chamfered surface of the card block 5 slides over the chamfered surfaces of the two clamping heads 8. After the card block 5 completely slides over the two clamping heads 8, the reset spring 9 rebounds to make the clamping head 8 slide and reset. At this time, the bottom of the card block 5 is against the top of the clamping head 8, and the card block 5 is fixed. The elastic pad 501 at the top of the block 5 is squeezed by the block 5 and pressed against the inner top of the spring shock absorber 1, which can prevent dust from entering the interior of the protective structure body 4 from the top of the block 5, and the dustproof effect is better. When the protective structure body 4 is damaged and needs to be replaced, pull the two pull rings 701, and the pin rod 7 drives the clamping head 8 to slide toward the inside of the shell 6 to compress the reset spring 9. The top of the two clamping heads 8 is separated from the bottom of the block 5, and the block 5 can be pressed down, so that the protective structure body 4 is folded and contracted, and then the connecting sleeve 3 is rotated to separate it from the connecting seat 2, and the protective structure body 4 can be disassembled and replaced, which is more convenient to operate.
