Description

Technical Field

[0001] This utility model relates to the technical field of shock absorber dust cover, specifically a shock absorber dust cover with a quick-installation structure. Background Technology

[0002] As a component of the car chassis, the shock absorber operates under extremely harsh conditions. It is frequently exposed to dust, mud, sand, and gravel. These external factors can easily cause local structural failures in the shock absorber, thus requiring special protection.

[0003] At the end of the shock absorber, a metal or plastic cover is usually used to protect the oil seal, preventing mud and sand from entering and the strong impact of the buffer block. The piston rod reciprocates and extends, and its surface is easily affected by dust, mud, sand and gravel, which can lead to oil leakage and failure. Therefore, a dust cover needs to be installed. The function of the dust cover during the operation of the shock absorber is to prevent mud and sand from entering and causing damage to the piston rod, thus avoiding oil leakage and failure of the shock absorber.

[0004] like Figure 1 As shown in the schematic diagram of the existing dust cover assembly structure, the interface between the dust cover 4 and the upper support 2 in the existing shock absorber dust cover is a snap-fit ​​structure. The upper support 2 is a full-circumferential boss structure, and the dust cover 4 is a full-circumferential groove structure. During the installation process, although the dust cover port has a flared guide structure, workers still need to use a large axial pushing force and sway to install the dust cover 4 onto the upper support 2. This process is time-consuming and labor-intensive, thus wasting labor costs.

[0005] While the existing technology described above can install dust covers, the on-site installation process uses pure interference fit, which is difficult, time-consuming, and labor-intensive, and cannot meet people's needs. Therefore, we need a shock absorber dust cover with a quick-installation structure. Utility Model Content

[0006] The purpose of this invention is to provide a shock absorber dust cover with a quick-installation structure to solve the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a dust cover for a shock absorber with a quick-installation structure, including a nut, an upper support, a buffer block, an oil reservoir, a protective cover, and a piston rod. The outer wall of the upper support is provided with a dust cover body, and the outer wall of the dust cover body is provided with a first snap-fit ​​structure. The outer wall of the upper support is provided with an upper spring pad, and the outer wall of the upper spring pad is respectively provided with a second snap-fit ​​structure, a third snap-fit ​​structure, and a fourth snap-fit ​​structure, which cooperate with the first snap-fit ​​structure to realize the installation and fixation of the dust cover body.

[0008] Preferably, the first snap-fit ​​structure consists of three protruding structures in the dust cover body, and the height of each of the three protruding structures is 4mm.

[0009] Preferably, the second snap-fit ​​structure consists of two grooves in the upper spring pad, each groove having a height of 4mm, which cooperate with the first snap-fit ​​structure.

[0010] Preferably, the third snap-fit ​​structure consists of three grooves in the upper spring pad, each groove having a height of 8mm, which cooperate with the first snap-fit ​​structure.

[0011] Preferably, the fourth snap-fit ​​structure is a groove structure provided in the upper spring pad, and the height of the groove structure is 4mm, which cooperates with the first snap-fit ​​structure.

[0012] Preferably, the fourth snap-fit ​​structure has notches at both ends to reduce rotational resistance.

[0013] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0014] This utility model adopts a partial slotted snap-fit ​​structure, which changes the original axial pushing force to the circumferential rotational force. Workers can easily assemble the dust cover body with the upper spring pad, and then rotate the dust cover body to complete the assembly. During the worker's installation process, the force required for installation is reduced, the installation time is saved, and time and effort are saved, thereby saving labor costs.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figure 2-5 As shown, a dust cover for a shock absorber with a quick-installation structure includes a nut 1, an upper support 2, a buffer block 3, an oil reservoir 5, a protective cover 6, and a piston rod 7. The outer wall of the upper support 2 is provided with a dust cover body 4, and the outer wall of the dust cover body 4 is provided with a first snap-fit ​​structure 8. The outer wall of the upper support 2 is provided with an upper spring pad 9, and the outer wall of the upper spring pad 9 is respectively provided with a second snap-fit ​​structure 10, a third snap-fit ​​structure 11, and a fourth snap-fit ​​structure 12, which cooperate with the first snap-fit ​​structure 8 to realize the installation and fixation of the dust cover body 4.

[0023] By adopting the above technical solution and using a partial slotted connection structure, the original axial pushing force is changed to circumferential rotational force. Workers can easily assemble the dust cover body 4 with the upper spring pad 9, and then rotate the dust cover body 4 to complete the assembly. During the worker's installation process, the force required for installation is reduced, the installation time is saved, and time and effort are saved, thereby saving labor costs.

[0024] Specifically, the first snap-fit ​​structure 8 consists of three protruding structures in the dust cover body 4, and the height of each of the three protruding structures is 4mm.

[0025] Through the above technical solution, these three protruding structures serve as key components for initial positioning and engagement. During installation, they can quickly and initially engage with the corresponding groove structure on the upper spring pad 9, guiding the dust cover body 4 to accurately align with the upper spring pad 9, thus providing a foundation for subsequent rotational installation.

[0026] Specifically, the second snap-fit ​​structure 10 consists of two grooves in the upper spring pad 9, each 4mm high, which cooperate with the first snap-fit ​​structure 8; the third snap-fit ​​structure 11 consists of three grooves in the upper spring pad 9, each 8mm high, which cooperate with the first snap-fit ​​structure 8; the fourth snap-fit ​​structure 12 consists of one groove in the upper spring pad 9, 4mm high, which cooperates with the first snap-fit ​​structure 8; and the fourth snap-fit ​​structure 12 has notches at both ends to reduce rotational resistance.

[0027] Through the above technical solution, the dust cover body 4 cooperates with the second snap-fit ​​structure 10, the third snap-fit ​​structure 11 and the fourth snap-fit ​​structure 12 on the upper spring pad 9. During installation, it is easy to connect at the initial stage. During the rotation installation process, it has a strong snap-fit ​​force to enhance the stability of the connection. By setting notch structures at both ends of the fourth snap-fit ​​structure 12, the resistance is reduced during rotation, making the installation process smoother and further improving the installation efficiency.

[0028] When using the dust cover, first align the dust cover body 4 with the upper spring pad 9, and assemble the first snap-fit ​​structure 8 with the third snap-fit ​​structure 11. Gently rotate the dust cover body 4 to assemble the first snap-fit ​​structure 8 with the second snap-fit ​​structure 10 and the fourth snap-fit ​​structure 12 until they are fully engaged. This reduces the force required for installation and saves installation time. This completes the entire process. Any content not described in detail in this manual is prior art known to those skilled in the art.
