Description

Technical Field

[0001] This utility model relates to the field of shock absorption equipment technology, specifically a combined shock absorption foot. Background Technology

[0002] Currently, most vibration damping feet used in the industry are of a split structure, meaning the damping foot and the mounting post are separate. This type of split damping foot requires two separate installation steps, resulting in low operational efficiency and high labor costs. Furthermore, the structure of split damping feet is relatively complex, with many parts, making it prone to errors or omissions during installation, affecting the overall performance and stability of the product. Therefore, there is an urgent need for a modular vibration damping foot to solve these problems. Utility Model Content

[0003] The purpose of this utility model embodiment is to provide a combined shock-absorbing foot to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A combined shock-absorbing foot includes: a rigid rubber fixing post and a soft elastomer, wherein the rigid rubber fixing post and the soft elastomer are an integral structure with their central axes on the same straight line. The soft elastomer is located outside the rigid rubber fixing post. The top of the rigid rubber fixing post has a sloping structure, and a rebound groove is formed on the rigid rubber fixing post to ensure that the rigid rubber fixing post has structural elasticity. The interior of the rigid rubber fixing post has a hollow structure, and a fixing screw is threaded at the center of the rigid rubber fixing post. The top of the soft elastomer has a fixing groove with a U-shaped cross section, and an annular shock-absorbing buffer cavity is formed inside the soft elastomer.

[0006] As a further aspect of this utility model: the hard plastic fixing post is provided with a screw anti-dislodgement buckle inside to prevent the fixing screw from falling off the hard plastic fixing post.

[0007] Compared with the prior art, the beneficial effects of this utility model are:

[0008] Simple structure: The original two parts are combined into one, reducing the number of parts and lowering production costs;

[0009] Easy to install: It simplifies the installation process, reduces labor costs, and improves installation efficiency;

[0010] Wide applicability: It can be applied to various components that require vibration damping, such as compressors, evaporators, and condensers, thus improving the versatility of materials;

[0011] Anti-loosening design: The hard plastic fixing post has anti-loosening screw clips inside to prevent the fixing screws from falling off during disassembly, solving the problem of screw loss during rework. Attached Figure Description

[0015] 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.

[0016] In this embodiment of the utility model, please refer to Figure 1 and Figure 2 A combined shock-absorbing foot includes: a rigid rubber fixing post 1 and a soft elastomer 4. The rigid rubber fixing post 1 and the soft elastomer 4 are an integral structure with their central axes on the same straight line. The soft elastomer 4 is located outside the rigid rubber fixing post 1. The top of the rigid rubber fixing post 1 has a sloping structure. The rigid rubber fixing post 1 has a rebound groove 2 to ensure that the rigid rubber fixing post 1 has structural elasticity. The interior of the rigid rubber fixing post 1 is a hollow structure. The center thread of the rigid rubber fixing post 1 is provided with a fixing screw 3. The top of the soft elastomer 4 has a fixing groove 6 with a U-shaped cross section. The interior of the soft elastomer 4 has an annular shock-absorbing buffer cavity 7.

[0017] By using a two-color injection molding machine to injection mold the rigid fixing post 1 and the soft elastomer 4 together, the two parts are combined into one, reducing the number of parts and one assembly step, thereby reducing labor costs. The shock-absorbing foot in this application is connected to the part to be damped by the fixing groove 6. The top of the rigid plastic fixing post 1 has a sloping structure and a spring-loaded groove 2, which makes the rigid plastic fixing post 1 have a certain degree of elasticity and can be used for the installation of different parts to be damped. The soft elastomer 4 plays a role in shock absorption and buffering. At the same time, the shock absorption and buffering cavity 7 provides additional buffering space to further improve the shock absorption performance.
