Description

Technical Field

[0001] This utility model relates to the field of copper-aluminum joint technology, and in particular to a copper-aluminum joint for precision copper pipes in refrigeration equipment that is resistant to tensile stress. Background Technology

[0002] Copper-aluminum fittings for precision copper tubing in refrigeration equipment are socket-type fittings that connect copper and aluminum tubing, typically made of copper and aluminum alloys. These fittings are characterized by corrosion resistance, high temperature resistance, and good thermal conductivity.1 In refrigeration equipment, copper-aluminum fittings are widely used for small piping connections in air conditioners, freezers, and other refrigeration equipment due to their good and reliable sealing performance and resistance to high temperature and humidity environments.

[0003] For example, Chinese patent CN203979690U discloses a copper-aluminum connector for connecting copper pipes and aluminum pipes. It includes a copper pipe and an aluminum pipe. One end of the copper pipe is pre-reduced to form a connector end. The connector end of the copper pipe is inserted into the aluminum pipe and resistively heat-welded. The connector end of the copper pipe includes a straight section, a beveled section, and a diameter-changing section. A groove is provided on the outer wall of the diameter-changing section. The inner wall protrusion of the aluminum pipe is pressed into the groove.

[0004] Although the above technical solutions have solved the corresponding technical problems, they still have the following drawbacks:

[0005] The copper-aluminum joint described above is not convenient for fixing the connected pipes, thus reducing the stability of the copper pipe connection. Utility Model Content

[0006] The purpose of this invention is to provide a copper-aluminum joint for precision copper pipes in refrigeration equipment that is resistant to tensile stress. While connecting to the pipe through the first and second connectors, a reinforcing ring is fixed to the pipe to be connected. At the same time, the connection between the pipe and the connector is reinforced by reinforcing bolts, which increases the stability of the connection between the pipe and the joint. Therefore, the tensile strength of the copper-aluminum joint is greatly increased, thereby improving the practicality of this invention.

[0007] To achieve the above objectives, the main technical solutions adopted by this utility model include:

[0008] A tensile-resistant copper-aluminum connector for precision copper tubing in refrigeration equipment, comprising:

[0009] The connector has a first connector at one end for connecting a precision copper tube of a refrigeration device, and a second connector at the other end. Both the first connector and the second connector have a reinforcing ring at the end away from the connector to limit the position of the copper tube to be connected.

[0010] The aforementioned tensile-resistant precision copper-aluminum connector for refrigeration equipment has a plurality of elastic reinforcing plates arranged at equal intervals fixedly connected to the side of the reinforcing ring.

[0011] The elastic reinforcing plate has a tapered cross-section. The tapered design of the elastic reinforcing plate increases the friction between the elastic reinforcing plate and the pipe to be connected when the elastic reinforcing plate is under force, thereby improving the stability between the pipe and the joint.

[0012] The aforementioned tensile-resistant precision copper-aluminum connector for refrigeration equipment, wherein the elastic reinforcing plate is fitted with a threaded ring that cooperates with the elastic reinforcing plate.

[0013] The inner wall of the threaded ring is provided with an internal thread, and the elastic reinforcing plate is provided with an external thread that meshes with the internal thread at the position corresponding to the internal thread. By twisting the threaded ring, under the action of the internal and external threads, the threaded ring can squeeze the inclined surface of the elastic reinforcing plate under the action of the inclined surface of the elastic reinforcing plate, thereby increasing the friction between the elastic reinforcing plate and the pipe to be connected, thus increasing the stability of the connection between the pipe and the joint.

[0014] The aforementioned tensile-resistant precision copper-aluminum connector for refrigeration equipment includes a reinforcing bolt between the connector and the reinforcing ring, with one end of the reinforcing bolt rotatably mounted on the side of the connector via a mounting bearing.

[0015] The reinforcing ring is fixedly connected to a fixing seat that works with the reinforcing bolt at the position corresponding to the reinforcing bolt. The reinforcing bolt is threadedly connected to a fixing sleeve at the position corresponding to the fixing seat. By tightening the fixing sleeve, the stability of the connection between the reinforcing ring and the connecting piece can be increased under the action of the threads of the fixing sleeve and the reinforcing bolt.

[0016] The aforementioned tensile-resistant precision copper-aluminum connector for refrigeration equipment has sealing rings on both sides of the connector, corresponding to the positions of the first and second connectors. The sealing rings increase the sealing performance when the pipe to be connected is connected to the first or second connector.

[0017] This utility model has at least the following beneficial effects:

[0018] This invention provides a tensile-resistant copper-aluminum connector for precision copper pipes in refrigeration equipment. While connecting to the pipe via a first and second connector, a reinforcing ring is fixed to the pipe to be connected. Simultaneously, reinforcing bolts reinforce the connection between the pipe and the connector, increasing the stability of the connection and thus maximizing the tensile strength of the copper-aluminum connector, thereby improving the practicality of this invention.

[0031] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0032] Please refer to Figures 1 to 4 As shown in the figure, an embodiment of the present invention provides a tensile-resistant copper-aluminum connector for precision copper tubes in refrigeration equipment, comprising: a connector 1, one end of the connector 1 is provided with a first connector 2 for connecting precision copper tubes in refrigeration equipment, and the other end of the connector 1 is provided with a second connector 3, and the ends of the first connector 2 and the second connector 3 away from the connector 1 are both provided with a reinforcing ring 301 that can limit the copper tube to be connected.

[0033] By adopting the above technical solution, while connecting to the pipeline through the first connector 2 and the second connector 3, the reinforcing ring 301 is fixed to the pipeline to be connected. At the same time, the reinforcing bolt 303 reinforces the connection between the pipeline and the connector 1, increasing the stability of the connection between the pipeline and the joint. Therefore, the tensile strength of the copper-aluminum joint is greatly increased, thereby improving the practicality of this utility model.

[0034] Please refer to Figures 1 to 4 As shown, the side of the reinforcing ring 301 is fixedly connected with several elastic reinforcing plates 3011 arranged at equal intervals.

[0035] Among them, the cross section of the elastic reinforcing plate 3011 is tapered. Through several tapered elastic reinforcing plates 3011, the friction between the elastic reinforcing plate 3011 and the pipe to be connected is increased when the elastic reinforcing plate 3011 is under force, thereby improving the stability between the pipe and the joint.

[0036] Please refer to Figures 1 to 4 As shown, a threaded ring 302 is fitted on the elastic reinforcing plate 3011 to cooperate with it.

[0037] The threaded ring 302 has an internal thread 3021 on its inner wall, and the elastic reinforcing plate 3011 has an external thread 3022 that meshes with the internal thread 3021 at the position corresponding to the internal thread 3021. By turning the threaded ring 302, and under the action of the threads of the internal thread 3021 and the external thread 3022, the threaded ring 302 can squeeze the inclined surface of the elastic reinforcing plate 3011, thereby increasing the friction between the elastic reinforcing plate 3011 and the pipe to be connected, thus increasing the stability of the connection between the pipe and the joint.

[0038] Please refer to Figures 1 to 4 As shown, a reinforcing bolt 303 is also provided between the connector 1 and the reinforcing ring 301. One end of the reinforcing bolt 303 is rotatably mounted on the side of the connector 1 through a mounting bearing 3031.

[0039] The reinforcing ring 301 is fixedly connected to a fixing seat 304 that works with the reinforcing bolt 303 at the position corresponding to the position of the reinforcing bolt 303. The reinforcing bolt 303 is threadedly connected to a fixing sleeve 3041 at the position corresponding to the fixing seat 304. By tightening the fixing sleeve 3041, and under the action of the threads of the fixing sleeve 3041 and the reinforcing bolt 303, the stability of the connection between the reinforcing ring 301 and the connector 1 can be increased.

[0040] Please refer to Figures 1 to 4As shown, sealing rings 201 are provided on both sides of the connector 1 and at positions corresponding to the first connector 2 and the second connector 3. The sealing rings 201 increase the sealing performance when the pipe to be connected is connected to the first connector 2 or the second connector 3.

[0041] The working principle of this utility model is as follows: by tightening the threaded ring 302, and under the action of the internal thread 3021 and the external thread 3022, the threaded ring 302 can compress the inclined surface of the elastic reinforcing plate 3011, thereby increasing the friction between the elastic reinforcing plate 3011 and the pipe to be connected, thus increasing the stability of the connection between the pipe and the joint. At the same time, by tightening the fixing sleeve 3041, and under the action of the threads of the fixing sleeve 3041 and the reinforcing bolt 303, the stability of the connection between the reinforcing ring 301 and the connector 1 can be increased. Therefore, the tensile strength of the copper-aluminum joint is greatly increased, thereby improving the practicality of this utility model.
