Description

Technical Field

[0001] The utility model relates to the technical field of refrigerator compressor sealing pieces, in particular to a vehicle-mounted refrigerator refrigeration compressor sealing piece. Background Art

[0002] The main function of the car refrigerator refrigeration compressor is to compress the gas refrigerant, converting it from low-pressure gas to high-pressure gas, and then condense and recirculate it through heat dissipation to achieve the refrigeration process. The car refrigerator refrigeration compressor seal is an important component inside the compressor, mainly used to ensure the airtightness of the compressor and prevent refrigerant leakage;

[0003] For example, the Chinese utility model provides a "rubber seal with high oxidation resistance and sealing performance" with patent number: 202323443534.5. The patent includes a sealing ring body, a sealing gasket is fixed on the inner side of the sealing ring body, and a sealing effect can be achieved by setting the sealing gasket. The sealing ring body is provided with an extrusion mechanism for squeezing the sealing gasket, and a connecting groove is provided on the sealing ring body. A limiting mechanism is provided in the connecting groove. By pressing the disc downward, the transmission rod, the movable rod and the fixed block can cooperate to make the inclined block squeeze the sealing gasket, so that the sealing gasket can fit tightly on the sealed component. Through the cooperation of the limiting hole and the limiting mechanism, the inclined block can squeeze and fix the sealing gasket, thereby achieving a better sealing effect.

[0004] Although the above document solves the problem that after the existing rubber seal is installed, the sealing part of the sealing ring may not fit tightly with the seal, resulting in unsatisfactory sealing effect of the sealing ring, there is still a disadvantage of poor performance of the sealing ring itself. The sealing ring itself does not contain corresponding anti-aging and weather-resistant materials, resulting in a short service life of the sealing ring. For this reason, a car refrigerator refrigeration compressor seal is introduced here. Utility Model Content

[0005] The utility model aims to provide a sealing sheet for a refrigeration compressor of a vehicle-mounted refrigerator, which has the advantage of a long service life.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a sealing plate for a refrigeration compressor of a vehicle refrigerator, comprising a sealing gasket, grooves being provided on both sides of the top of the sealing gasket, springs being fixedly connected on both sides of the bottom of the inner cavity of the groove, a convex block being fixedly connected to the top of the spring, an upper sealing gasket being fixedly connected to the top of the convex block, the upper sealing gasket being made of the same material as the sealing gasket, the sealing gasket comprising a base layer, a heat-resistant layer being fixedly connected to the outer surface of the base layer, an elastic layer being fixedly connected to the outer surface of the heat-resistant layer, and a corrosion-resistant layer being fixedly connected to the outer surface of the elastic layer.

[0007] As a preferred solution, the base layer is made of silicone rubber, and the heat-resistant layer is made of glass fiber.

[0008] As a preferred solution, the elastic layer is made of a polyurethane fiber layer, and the corrosion-resistant layer is made of a fluororubber layer.

[0009] As a preferred solution, side grooves are provided on both sides of the inner cavity of the groove, the inner cavity of the side grooves is movably connected to a limiting frame, and the end of the limiting frame away from the side groove is fixedly connected to the bottom of the convex block.

[0010] As a preferred solution, both sides of the top of the sealing gasket are provided with card slots, and both sides of the bottom of the upper sealing gasket are fixedly connected with card blocks.

[0011] As a preferred solution, a lower sealing gasket is fixedly connected to the bottom of the sealing gasket, and the lower sealing gasket is made of the same material as the upper sealing gasket.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0013] 1. The utility model has a heat-resistant layer, an elastic layer and a corrosion-resistant layer. The glass fiber has high tensile strength and good heat resistance, thereby improving the tensile strength and heat resistance of the sealing gasket, so that the sealing gasket will not be affected by high temperature and reduce the sealing properties. The polyurethane fiber layer has good resilience, thereby improving the elasticity of the sealing gasket, so that the bearing capacity of the sealing gasket is increased. The fluororubber layer has excellent oil resistance, acid and alkali resistance, oxidation resistance and solvent resistance, and can be used for a long time in high temperature and harsh chemical environments. The three groups of functional layers greatly improve the service life of the refrigeration compressor seal.

[0014] 2. The utility model uses grooves, springs, convex blocks and upper sealing gaskets. As the two compressor accessories approach each other, the accessories will squeeze the upper sealing gasket, and the upper sealing gasket will squeeze the spring through the convex block. The spring uses its own elastic force to apply resistance to the convex block and the upper sealing gasket, so that the two sides of the refrigeration compressor sealing plate are tightly pressed against the sides of the two refrigeration compressor accessories that are close to each other, greatly improving the sealing performance.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] Secondly, the term "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments. Example 1:

[0022] See also Figure 1-Figure 4 As shown, the utility model provides a sealing sheet for a refrigeration compressor of a vehicle refrigerator, comprising a sealing gasket 1, grooves 2 are provided on both sides of the top of the sealing gasket 1, springs 3 are fixedly connected on both sides of the bottom of the inner cavity of the groove 2, a convex block 4 is fixedly connected to the top of the spring 3, an upper sealing gasket 5 is fixedly connected to the top of the convex block 4, and the upper sealing gasket 5 is made of the same material as the sealing gasket 1. The sealing gasket 1 comprises a base layer 101, a heat-resistant layer 102 is fixedly connected to the outer surface of the base layer 101, an elastic layer 103 is fixedly connected to the outer surface of the heat-resistant layer 102, and the elastic layer 103 is fixedly connected to the outer surface of the elastic layer 103. The outer surface of 3 is fixedly connected with a corrosion-resistant layer 104. During the use of the refrigeration compressor sealing sheet, the glass fiber has high tensile strength and good heat resistance, thereby improving the tensile strength and heat resistance of the sealing gasket 1, so that the sealing gasket 1 will not be affected by high temperature and reduce the sealing properties. The polyurethane fiber layer has good resilience, thereby improving the elasticity of the sealing gasket 1, so that the bearing capacity of the sealing gasket 1 is increased. The fluororubber layer has excellent oil resistance, acid and alkali resistance, oxidation resistance and solvent resistance, and can be used for a long time in high temperature and harsh chemical environments.

[0023] This technical solution sets up the application of heat-resistant layer 102, elastic layer 103 and corrosion-resistant layer 104. By setting up three groups of functional layers, the heat resistance, resilience and corrosion resistance of the refrigeration compressor sealing piece are greatly improved, and the service life of the refrigeration compressor sealing piece is generally improved. Example 2:

[0024] On the basis of embodiment 1, the present invention is as follows Figure 2-Figure 4 As shown, it is disclosed that the material of the base layer 101 is silicone rubber, the material of the heat-resistant layer 102 is glass fiber, the material of the elastic layer 103 is a polyurethane fiber layer, and the material of the corrosion-resistant layer 104 is a fluororubber layer. Side grooves are provided on both sides of the inner cavity of the groove 2, and the inner cavity of the side groove is movably connected to a limit frame, and the end of the limit frame away from the side groove is fixedly connected to the bottom of the convex block 4.

[0025] The above technical scheme is adopted mainly to achieve the purpose of improving the heat resistance, resilience and corrosion resistance of the sealing gasket 1, and improving the movement stability of the upper sealing gasket 5. The glass fiber has high tensile strength and good heat resistance, thereby improving the tensile strength and heat resistance of the sealing gasket 1, so that the sealing gasket 1 will not be affected by high temperature and reduce the sealing properties. The polyurethane fiber layer has good resilience, thereby improving the elasticity of the sealing gasket 1, so that the bearing capacity of the sealing gasket 1 is increased. The fluororubber layer has excellent oil resistance, acid and alkali resistance, oxidation resistance and solvent resistance. The limit frame moves in the side groove of the matching size as the convex block 4 moves, and can keep the upper sealing gasket 5 on the top of the convex block 4 from shaking when it moves under pressure. Example 3:

[0026] On the basis of embodiment 2, the present invention is as follows Figure 2 and Figure 4 As shown, it is disclosed that both sides of the top of the sealing gasket 1 are provided with card grooves, both sides of the bottom of the upper sealing gasket 5 are fixedly connected with card blocks, and the bottom of the sealing gasket 1 is fixedly connected with a lower sealing gasket, and the lower sealing gasket and the upper sealing gasket 5 are made of the same material.

[0027] The above technical solution is adopted mainly to achieve the purpose of improving the clamping tightness between the top of the sealing gasket 1 and the bottom of the upper sealing gasket 5 and improving the sealing performance of the bottom of the sealing gasket 1. The clamping block is inserted into the clamping groove at the top of the sealing gasket 1 as the upper sealing gasket 5 moves downward, which can greatly improve the clamping tightness between the upper sealing gasket 5 and the sealing gasket 1. The bottom of the lower sealing gasket is provided with dense anti-slip grooves, which makes the bottom of the compressor sealing plate fit more tightly with the surface of the compressor accessories and is not easy to loosen.

[0028] The working principle of the present invention is: place the compressor sealing plate on the top of one of the compressor accessories, move the other installation accessory close to the top of the sealing plate, as the two compressor accessories approach, the accessories will squeeze the upper sealing gasket 5, and the upper sealing gasket 5 will squeeze the spring 3 through the convex block 4, and the spring 3 will give the convex block 4 and the upper sealing gasket 5 a resistance through its own elastic force, so that the two sides of the refrigeration compressor sealing plate are tightly pressed against the side of the two refrigeration compressor accessories close to each other. During use, the compressor sealing plate passes through the heat-resistant layer 102, the elastic layer 103 and the corrosion-resistant layer 104, and the glass fiber has high tensile strength and good heat resistance, thereby improving the tensile strength and heat resistance of the sealing gasket 1, so that the sealing gasket 1 will not be affected by high temperature and reduce the sealing properties. The polyurethane fiber layer has good resilience, thereby improving the elasticity of the sealing gasket 1, so that the bearing capacity of the sealing gasket 1 is increased. The fluororubber layer has excellent oil resistance, acid and alkali resistance, oxidation resistance and solvent resistance, and can be used for a long time in high temperature and harsh chemical environments. The three groups of functional layers greatly improve the service life of the refrigeration compressor sealing plate.
