Description

Technical Field

[0001] This utility model relates to the field of air conditioning metal pipe technology, specifically a sealing structure for an air conditioning metal pipe connector. Background Technology

[0002] Air conditioning metal pipes are key pipes in air conditioning systems used to transport refrigerant, connect indoor and outdoor units and various components. Their performance directly affects the cooling (heating) efficiency, sealing performance and service life of the air conditioner.

[0003] Patent CN221034435U discloses a metal pipe connection structure, belonging to the field of metal pipe technology. This metal pipe connection structure includes a metal pipe and a connection mechanism. The connection mechanism connects two metal pipes through a connector. An auxiliary sealing element is provided between the two metal pipes. The auxiliary sealing element works with the connector to seal and splice the metal pipes. The connector pulls the two metal pipes together, causing the metal pipes to squeeze the auxiliary sealing element for connection. The auxiliary sealing element is then adjusted for secondary fixation. By rotating the second screw ring, the second locking ring is squeezed and locked to one end of the metal pipe, completing the sealed connection of the two metal pipes. By fixing the connector to the outside of the two metal pipes, the secondary processing of the metal pipes is reduced, and the two metal pipes can be easily disassembled and reused when disassembly is required.

[0004] However, in actual use, the above-mentioned patent requires manual tightening of the bolts. Manual operation has poor precision, and when the tightening force is not uniform, it will cause uneven force on the auxiliary sealing component. For example, one side is squeezed too tightly and the other side is squeezed too little, resulting in poor sealing between the metal pipes. The bolts need to be tightened gradually multiple times, resulting in low installation efficiency. Utility Model Content

[0005] The purpose of this utility model is to provide a sealing structure for air conditioning metal pipe connectors to solve the problems mentioned in the background art, such as the need for manual tightening of bolts, poor precision of manual operation, uneven force on auxiliary sealing components when tightening force is inconsistent, such as excessive compression on one side and insufficient compression on the other side, resulting in poor sealing between metal pipes, and the need for multiple gradual tightening of bolts, which leads to low installation efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a sealing structure for an air conditioning metal pipe connector, comprising a metal pipe, a connecting sleeve, a first sealing ring, and a first clamp. The connecting sleeve is fitted onto the outer wall of the metal pipe. The first sealing ring is located on the inner side of the connecting sleeve. The first clamp is clamped onto the outer wall of the first sealing ring. A sleeve is integrally formed on the right side of the inner wall of the connecting sleeve. A connector is integrally formed at the end of the connecting sleeve. A rotating component is welded to one end of the first clamp. A second clamp is rotatably connected to the connecting end of the rotating component. A fixing component is integrally formed at the other end of the first clamp and the end of the second clamp. A third groove is formed at the end of the fixing component. A connecting shaft is fixedly connected between the inner cavity of the lower third groove. A screw is rotatably fitted onto the outer wall of the connecting shaft.

[0007] As a further description of the above technical solution:

[0008] The metal tube has a first groove at its connecting end, and the metal tube is made of brass.

[0009] As a further description of the above technical solution:

[0010] The connector has a second groove at its end, and a rubber ring is fitted onto the outer wall of the sleeve. A spring ring is snapped around the outer wall of the rubber ring.

[0011] As a further description of the above technical solution:

[0012] The first sealing ring has a second sealing ring integrally formed at both ends, and the second sealing ring is engaged in the inner cavity of the second groove.

[0013] As a further description of the above technical solution:

[0014] The screw is movably engaged in the inner cavity of the third groove on the upper side, and a tightening sleeve is threadedly connected to the upper side of the outer wall of the screw.

[0015] As a further description of the above technical solution:

[0016] Both the first clamp and the second clamp are fitted onto the outer wall of the connector, and the tightening screw is located above the upper fixing member.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. The sealing structure of this air conditioner metal pipe connector, by fitting the connecting sleeve onto the outer wall of the metal pipe and simultaneously inserting the sleeve into the inner wall of the metal pipe, results in high overall friction and a firm connection. The two connectors are engaged with the first and second sealing rings, and the outer walls of the two connectors are tightened by the first and second clamps. By rotating and tightening the screw sleeve, the first and second clamps and the outer walls of the two connectors are gradually tightened. No precise manual operation is required, the connection has good sealing performance, and the installation efficiency is high.

[0019] 2. The sealing structure of the air conditioner metal pipe connector is achieved by attaching a rubber ring to the sleeve, with a spring ring clamped around the outer wall of the rubber ring. The elastic deformation of the spring ring generates continuous extrusion pressure, resulting in continuous sealing pressure between the metal pipe and the connecting sleeve, thus making the sealing effect more long-lasting.

[0028] This utility model provides a sealing structure for air conditioning metal pipe connectors, eliminating the need for precise manual operation, ensuring good sealing at the connection, high installation efficiency, and a longer-lasting sealing effect. Please refer to [link / reference]. Figure 1-4 It includes a metal pipe 100, a connecting sleeve 200, a first sealing ring 300, and a first clamp 400;

[0029] Please refer to it again. Figure 1 Metal tube 100 is used to connect connecting sleeve 200.

[0030] Please refer to it again. Figure 1 and Figure 4 The inner side wall of the connecting sleeve 200 is integrally formed with a sleeve 210, and the end of the connecting sleeve 200 is integrally formed with a connector 220. The connecting sleeve 200 is sleeved on the outer side wall of the metal tube 100. The connecting sleeve 200 is used to connect the sleeve 210 and the connector 220 and to connect and fix them to the metal tube 100.

[0031] Please refer to it again. Figure 1-2 The first sealing ring 300 is located inside the connecting sleeve 200. The first sealing ring 300 is used to seal the mating point of the connector 220 with the second sealing ring 310.

[0032] Please refer to it again. Figure 3 One end of the first clamp 400 is welded with a rotating part 410, and the connecting end of the rotating part 410 is rotatably connected to the second clamp 420. The other end of the first clamp 400 and the end of the second clamp 420 are both integrally formed with a fixing part 430. The end of the fixing part 430 has a third groove 440. A connecting shaft 450 is fixedly connected between the inner cavity of the lower third groove 440. A screw 460 is rotatably sleeved on the outer wall of the connecting shaft 450. The first clamp 400 is clamped to the outer wall of the first sealing ring 300. The first clamp 400 and the second clamp 420 are used to fix the two connectors 220. The rotating part 410 is used for rotatable connection between the first clamp 400 and the second clamp 420. The fixing part 430 is used for connection between the first clamp 400 and the second clamp 420. The connecting shaft 450 is used for the screw 460 to rotate within it.

[0033] In summary: by fitting the connecting sleeve 200 onto the outer wall of the metal pipe 100, while simultaneously inserting the sleeve 210 into the inner wall of the metal pipe 100, the overall friction is high, resulting in a firm connection. The two connectors 220 are engaged with the first sealing ring 300 and the second sealing ring 310. The outer walls of the two connectors 220 are secured by the first clamp 400 and the second clamp 420. By rotating and tightening the screw sleeve 470, the first clamp 400, the second clamp 420, and the outer walls of the two connectors 220 are gradually secured. No precise manual operation is required, resulting in good sealing at the connection and high installation efficiency.

[0034] Please refer to it again. Figure 1 and Figure 4 The metal tube 100 has a first groove 110 at its connecting end, and the metal tube 100 is made of brass.

[0035] Please refer to it again. Figure 1 and Figure 4 The connector 220 has a second groove 230 at its end, and a rubber ring 240 is fitted onto the outer wall of the sleeve 210. A spring ring 250 is snapped around the outer wall of the rubber ring 240.

[0038] Please refer to it again. Figure 1 and Figure 3The first clamp 400 and the second clamp 420 are both sleeved on the outer side wall of the connector 220, and the tightened screw sleeve 470 is located above the upper fixing member 430.

[0039] In summary: by attaching a rubber ring 240 to the sleeve 210, and clamping a spring ring 250 around the outer wall of the rubber ring 240, the elastic deformation of the spring ring 250 generates continuous extrusion pressure, resulting in continuous sealing pressure between the metal tube 100 and the connecting sleeve 200, thus making the sealing effect more long-lasting.

[0040] In practical use, those skilled in the art shall place the connecting sleeve 200 on the outer wall of the joint of the two metal pipes 100, while inserting the sleeve 210 into the inner wall of the metal pipe 100.
