Description

Technical Field

[0001] This utility model relates to the field of refrigeration compressor technology, specifically to an integrated support block compression spring assembly support structure and compressor. Background Technology

[0002] Traditional compressor support structure, such as Figure 2 As shown, most compressors use a unidirectional interference fit between the compression spring and the upper and lower support blocks. One end of the spring is interference-fitted with either the upper or lower support block, while the other end is loosely fitted. During compressor transport, if the compressor is inverted, the loosely fitted end may detach, causing malfunctions. Using a double interference fit would complicate assembly, making it difficult to ensure simultaneous installation of both the upper and lower interference fits. Improper installation can lead to additional noise and vibration issues. Furthermore, over time, the interference fit on the support blocks wears and loosens, gradually losing its effectiveness and increasing the risk of detachment. Summary of the Invention

[0003] The purpose of this utility model is to solve the problems existing in the prior art and to provide an integrated support block compression spring assembly support structure and compressor.

[0004] The specific solution of this utility model is: an integrated support block and spring assembly support structure, including an upper support block, a spring and a lower support block. Both the upper support block and the lower support block are provided with a base. A protruding limiting cap is provided on one side of the base. The diameter of the limiting cap is smaller than that of the base. The upper end and the lower end of the spring are each provided with a clamping ring. The middle is a compressible section. The limiting cap is located in the compressible section. The clamping ring at the upper end of the spring is fixedly connected to the base of the upper support block, and the clamping ring at the lower end of the spring is fixedly connected to the base of the lower support block.

[0005] Furthermore, the upper end of the compression spring is fused with the base of the upper support block, and the lower end of the compression spring is fused with the base of the lower support block.

[0006] Furthermore, the base thickness of the upper and lower support blocks is 5-8mm, and the thickness of the compression spring's coil is greater than the thickness of the base.

[0007] Furthermore, a gap is provided between the compressible section of the compression spring and the limiting caps of the upper and lower support blocks.

[0008] This utility model also provides a compressor equipped with the above-mentioned integrated support block compression spring assembly support structure.

[0009] Compared with the prior art, this utility model has the following advantages: 1. It can meet the installation requirements of bidirectional interference fit and reduce the risk of compression spring dislodgement; 2. In the assembly process of compressor support structure, it reduces assembly steps and reduces process costs. Attached Figure Description

[0013] See Figure 1 This embodiment is an integrated support block and spring assembly support structure, including an upper support block 3, a spring, and a lower support block 1. Both the upper support block 3 and the lower support block 1 are provided with a base. A protruding limiting cap 2 is provided on one side of the base. The diameter of the limiting cap 2 is smaller than that of the base. The upper and lower ends of the spring are each provided with a clamping ring 5, and the middle is a compressible section 4. The limiting cap 2 is located within the compressible section 4. The clamping ring 5 at the upper end of the spring is fixedly connected to the base of the upper support block 3, and the clamping ring 5 at the lower end of the spring is fixedly connected to the base of the lower support block 1. Furthermore, the clamping ring 5 at the upper end of the spring is fused with the base of the upper support block 3, and the clamping ring 5 at the lower end of the spring is fused with the base of the lower support block 1.

[0014] Furthermore, the base thickness of the upper support block 3 and the lower support block 1 is 5-8mm, and the thickness of the compression spring coil 5 is greater than the thickness of the base.

[0015] Furthermore, a gap is provided between the compressible section 4 of the compression spring and the limiting cap 2 of the upper support block 3 and the lower support block 1. This utility model also provides a compressor equipped with the aforementioned integrated support block and compression spring assembly support structure.

[0016] During the manufacturing process of this utility model, the compression spring is pre-embedded in the molten raw material of the support block during the injection molding and extrusion molding of the support block. After the raw material of the support block cools and solidifies, the upper and lower clamping coils 5 of the compression spring are connected to the base part of the upper and lower support blocks 1.

[0017] Since the compressible working coil of the compression spring is not embedded, it is still compressible and elastic, so this component still retains the function of vibration isolation and damping.

[0018] When assembling this invention on a compressor, the upper spring support block base is connected to the stator screw on the compressor core via an interference fit. Pressing down on the lower spring support block compresses the working coil of the spring, tightening the upper and lower spring support blocks together to ensure the upper support block 3 is properly installed. Then, the compressor core with this support structure is installed into the compressor housing. During the installation process, pressing down on the compressor core ensures that the limiting caps 2 of the upper and lower support blocks 1 are in close contact, thus ensuring the interference fit between the lower support block 1 base and the support pin inside the housing. Traditional interference fit support structures transmit force through springs, which are inconvenient to install due to the elasticity of the springs themselves. This invention improves upon the traditional elastic non-contact transmission by changing it to semi-rigid contact transmission, making it easier to install, meeting the requirements for bidirectional interference fit installation, and reducing the risk of compressor spring dislodgement.
