[0028] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0029] like Figure 1-9 As shown, this utility model provides an automotive shock absorber, comprising:

[0030] The shock absorber body 1 has two mounting rings 11 arranged vertically around its periphery.

[0031] There are two first semi-circular wrapping sleeves 201. The two first semi-circular wrapping sleeves 201 together form a complete circle and wrap the shock absorber body 1 inside it. The bottom of each of the two first semi-circular wrapping sleeves 201 is provided with a sliding groove 21.

[0032] Two semi-circular wrapping sleeves 2 are provided. The two semi-circular wrapping sleeves 2 slide up and down and are sealed inside the two grooves 21 respectively. The two semi-circular wrapping sleeves 2 close together to form a complete circle.

[0033] There are two locking mechanisms 3, which are respectively installed on the left side of the two mounting rings 11. The two locking mechanisms 3 are used to fix the two first semi-circular wrapping sleeves 201 and the two second semi-circular wrapping sleeves 2. Specifically, each of the two locking mechanisms 3 includes a locking block 31, which is fixedly installed on the left side of the two mounting rings 11. Connecting blocks 32 are fixedly installed on the left side of the periphery of the two first semi-circular wrapping sleeves 201 and the two second semi-circular wrapping sleeves 2. The two locking blocks 31 are respectively located between the two connecting blocks 32 on the upper and lower sides. Locking components are provided between the two connecting blocks 32 on the upper and lower sides and the two locking blocks 31.

[0034] In the initial state, when installing the two first semi-circular sleeves 201 and the two second semi-circular sleeves 2, the two first semi-circular sleeves 201 and the two second semi-circular sleeves 2 are closed together to form a complete circular telescopic sleeve, which covers the telescopic part of the shock absorber body 1. Then, the locking assembly is used to lock it. In this way, the two first semi-circular sleeves 201 and the two second semi-circular sleeves 2 provide protection to prevent sand, gravel and rainwater from entering the shock absorber body 1 during vehicle operation. When it is necessary to replace the two first semi-circular sleeves 201 and the two second semi-circular sleeves 2, the locking assembly is released and the two first semi-circular sleeves 201 and the two second semi-circular sleeves 2 are separated. The operation is simple and convenient, and there is no need to disassemble the shock absorber body 1.

[0035] The locking assembly includes a limiting block 33, a locking block 31, and a rear connecting block 32, each with a limiting groove 34. The limiting block 33 is fixedly installed at the rear of the front connecting block 32. The rear side of the limiting block 33 passes through two limiting grooves 34 in sequence. The rear side of the limiting block 33 has an inclined surface 35. An assembly box 36 is fixedly installed on the top of the rear connecting block 32. A fixing groove 361 is opened on the rear side of the top of the limiting block 33. A fixing block 37 is slidably assembled inside the assembly box 36. The lower end of the fixing block 37 extends into the fixing groove 361. A spring 38 is fixedly installed on the upper end of the fixing block 37. The upper end of the spring 38 is fixedly connected to the upper side inside the assembly box 36. A pull rod 39 is fixedly installed on the upper end of the fixing block 37. The upper end of the pull rod 39 extends out of the assembly box 36 and is fixedly installed with a pull block. The pull rod 39 and the assembly box 36 are slidably and sealingly connected.

[0036] Taking one of the locking components as an example, when the two first semi-circular wrapping sleeves 201 and the two second semi-circular wrapping sleeves 2 are closed, the limiting block 33 passes through the two limiting grooves 34 in sequence. During this period, the inclined surface 35 of the limiting block 33 will abut against the lower end of the fixing block 7. The pushing force generated by the inclined surface 35 pushes the fixing block 7 upward. The paper fixing block 7 moves upward to the top of the limiting block 33. After the two first semi-circular wrapping sleeves 201 and the two second semi-circular wrapping sleeves 2 are closed and tightly abutted, the fixing groove 361 will align with the fixing block 37. Under the action of the spring 38, the fixing block 37 enters the fixing groove 361. The limiting block 33 is fixed, and the upper and lower limiting blocks 33 are used in the same way, so that the two first semi-circular wrapping sleeves 201 and the two second semi-circular wrapping sleeves 2 can be fixed. When the shock absorber body 1 performs shock absorption extension and contraction, the two second semi-circular wrapping sleeves 2 will slide inside the two sliding grooves 21. When replacing the two first semi-circular wrapping sleeves 201 and the two second semi-circular wrapping sleeves 2, pull the pull rod 39 upward to pull the fixing block 37 completely into the assembly box 36 to release the fixation. In this way, the two first semi-circular wrapping sleeves 201 and the two second semi-circular wrapping sleeves 2 can be separated. The operation is quick.

[0037] The two first semi-circular wrapping sleeves 201 and the two second semi-circular wrapping sleeves 2 are distributed front to back. The first semi-circular wrapping sleeve 201 and the second semi-circular wrapping sleeve 2 at the rear are provided with insertion grooves 22 on the left and right sides of the front. The first semi-circular wrapping sleeve 201 and the second semi-circular wrapping sleeve 2 at the rear are fixedly installed with insertion blocks 23 that are slidably and sealingly connected to the insertion grooves 22 on the left and right sides of the rear.

[0038] After the first semi-circular wrapping sleeve 201 and the two second semi-circular wrapping sleeves 2 are closed, the corresponding insertion block 23 will be inserted into the insertion groove 22 to seal the gap between the first semi-circular wrapping sleeve 201 and the two second semi-circular wrapping sleeves 2, thereby further improving the sealing performance.

[0039] Two mounting rings 11 are fixedly mounted with abutment rings 4 on one side close to each other. The two abutment rings 4 are located inside the two first semi-circular wrapping sleeves 201 and the two second semi-circular wrapping sleeves 2, respectively. Both abutment rings 4 are provided with elastic sealing rings around their periphery.

[0040] The upper and lower abutment rings 4 are used for abutment during installation of the two first semi-circular wrapping sleeves 201 and the two second semi-circular wrapping sleeves 2. One set of the first semi-circular wrapping sleeves 201 and the second semi-circular wrapping sleeves 2 can be abutted against the periphery of the two abutment rings 2 before installing the other set of the first semi-circular wrapping sleeves 201 and the second semi-circular wrapping sleeves 2, which facilitates positioning. When the two first semi-circular wrapping sleeves 201 and the two second semi-circular wrapping sleeves 2 are closed, a little force is applied to the two elastic sealing rings to apply a certain compressive force, which can seal the gap between the first semi-circular wrapping sleeves 201 and the two second semi-circular wrapping sleeves 2 and the two abutment rings 4, further improving the sealing performance.

[0041] The device is used as follows:

[0042] When protection of the shock absorber body 1 is required, the workers align the two first semi-circular sleeves 201 and the two second semi-circular sleeves 2 with the two abutment rings 4 and close them. During closure, the four insertion blocks 23 will insert into the four insertion slots 22, completing the sealing of the gap between the two first semi-circular sleeves 201 and the two second semi-circular sleeves 2. At the same time, the two limiting blocks 33 will pass through the two locking blocks 31 in sequence and extend into the rear connecting block 32. The inclined surface 35 can be used to push the fixing block 37 upward. After the two first semi-circular covers 201 and the two second semi-circular covers 2 are fully closed, the two fixing blocks 37 automatically insert into the two fixing slots 361 to lock them in place. No additional operation is required, making it simple and convenient to use. When it is necessary to disassemble and replace the shock absorber body 1 in the future, it is not necessary to disassemble the shock absorber body 1. Simply pull up the two pull blocks to release the connection between the fixing blocks 37 and the fixing slots 361 to unlock the device. This allows the staff to disassemble the two first semi-circular covers 201 and the two second semi-circular covers 2 for replacement. It is simple and convenient to use.

[0043] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
