TECHNICAL FIELD

[0001] The utility model relates to air conditioning pipeline connection frock technical field, concretely for a kind of for air conditioner refrigeration pipe adapter. BACKGROUND

[0002] In the refrigeration fitting assembly process, many refrigeration pipes need to be connected to each other to form a complete refrigeration pipeline. The adapter is used to connect multiple groups of refrigeration pipes. The conventional adapter is usually connected by fixed welding. Since the temperature inside the refrigeration pipe may drop suddenly, the welded part may crack under the condition of thermal expansion and cold contraction, which may cause gas leakage.

[0003] For example, application No. 202322824868.0, named "a refrigeration air conditioner adapter", or application No. 202320910985.6, named "a refrigeration air conditioner adapter", sets up a relatively complex assembly structure (external) at the inner side or outer periphery of the adapter. Although it plays a connecting role, the actual manufacturing difficulty is relatively large, and the assembly and disassembly are relatively cumbersome, especially when assembling and disassembling in the air conditioner.

[0004] To solve the above problems, the present case arises. INVENTION CONTENTS

[0008] To achieve the above purpose, the utility model is implemented by the following technical scheme: an adapter for air conditioner refrigeration pipe, comprising a connecting seat for connecting and assembling pipes, the end of the connecting pipe is provided with a circumferentially outwardly expanded annular adapter, and an external sleeve is provided between the connecting pipe and the connecting seat, the connecting pipe is embedded in the inside of the connecting seat, and then limited to the outside of the connecting seat by the sleeve, and the connecting pipe is fixed on the connecting seat.

[0009] Preferably, the connecting seat includes a pipe body, which penetrates both sides along its axial direction, wherein the pipe body is inwardly tapered inwardly along the axial inside to form a sunken body, and the inside of the pipe body is outwardly expanded to form a limiting body.

[0010] Preferably, the outer diameter of the adapter is matched with the caliber of the pipe body, and is larger than the through slot formed by the sunken body, and an inner slot is formed in the limiting body, which has the same caliber size as the pipe body.

[0011] Preferably, the sinkhole is made of a deformable metal material.

[0012] Preferably, the sinkhole has a long groove extending through its inner wall in the circumferential direction.

[0013] Preferably, the sleeve includes a sleeve body that extends through both sides, and the rear side of the sleeve body is provided with an extension block that gradually protrudes inward and is close to the outer wall of the connecting pipe. The front side of the sleeve body is provided with an internal thread, and the middle part of the pipe body is provided with a matching external thread.

[0014] (III) Beneficial Effects

[0015] After adopting the above technical solution, this utility model has the following advantages compared with the prior art: This utility model is an adapter for refrigeration pipes of air conditioners. Through the ingenious design of the adapter, after the connecting pipe is quickly inserted, the adapter uses a deformable material at the connection point of the connecting pipe. Then, by means of an external sleeve, it can be horizontally pushed to the connection point of the two pipes to achieve a tight connection. The structure is simple and convenient to use.

[0019] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0020] like Figure 1 As shown: An adapter for refrigeration pipes of an air conditioner includes a connector 2 for quick assembly between connecting pipes 1, wherein the end of the connecting pipe 1 is provided with an annular connecting seat 4 that expands outward in a circumferential direction (which may be achieved by stamping or other methods). When the connecting pipe 1 is embedded in the interior of the connector 2, the outer side of the connector 2 is restricted by an external sleeve 3 and the connecting pipe 1 is fixed to the connector 2.

[0021] See appendix Figure 2As shown, the connecting seat 2 comprises a pipe body 21 which penetrates through both sides along its axial direction, wherein the pipe body 21 is first inwardly convergent to form a sunken body 22 along the axial inner side, and is outwardly expanded to form a limiting body 23 at its inner side, wherein the outer diameter size of the connecting seat 4 is adapted to the caliber of the pipe body 21, and is larger than the through slot 26 formed by the sunken body 22, and the inner slot 25 opened in the limiting body 23 has the same radial size as the caliber of the pipe body 21.

[0022] Secondly, the sunken body 22 needs to adopt a deformable metal material (such as a conventional deformation memory alloy, a new type of deformable aluminum alloy, a liquid metal, etc., and of course some deformation plastics can also be used), and a long slot 24 is opened through the inner wall in the circumferential direction, so that it can be outwardly expanded and deformed when the connecting seat 4 is embedded, and can be limited by the slot wall of the inner slot 25 after being placed into the connecting body 23 and the connecting seat 4.

[0023] Since the sunken body 22 will deform under stress after the connecting pipe 1 is embedded, it is still easy to be detached from the connecting pipe 1, therefore, the sleeve seat 3 designed in the embodiment is used to fasten the two.

[0024] The sleeve seat 3 comprises a sleeve body 31 which penetrates through both sides, the rear side of the sleeve body 31 is provided with an extension block 32 which is gradually raised inwardly and is attached to (a gap needs to be left) the outer wall of the connecting pipe 1, and the front side is provided with an inner thread 33, and meanwhile an adapted outer thread 27 is opened in the middle of the pipe body 21. Wherein the slot opening in the inner side of the sleeve body 31 and the size of the outer wall of the sleeve seat 3 are adapted to be able to be placed, and secondly, the connecting body is continuously extruded and partially filled into the outer periphery of the sunken body 22 during the placement process, so that the deformable sunken body 22 is subjected to the constraint force of the periphery, thereby avoiding the connecting pipe 1 from being forced out.

[0025] The above description is based on the embodiment, through the above description, the relevant staff can make various changes and modifications without deviating from the scope of the idea of the present application. The scope of the use of the new technology is not limited to the content in the specification, and the scope of protection must be determined according to the scope of claims.
