Thus, the present application is not intended to be limited to the embodiments shown, but is to be accorded the widest scope consistent with the principles and features disclosed herein.

In one aspect, the present embodiment provides a joint, as shown in fig. 1 to 5, including a first connector 10, a second connector 20, and a fitting 30; when the first connecting piece 10 and the second connecting piece 20 are in a connected state, the first connecting piece 10 and the second connecting piece 20 are limited in the direction away from each other, namely, the first connecting piece 10 and the second connecting piece 20 are limited in the direction away from each other, so that the purpose of preventing disassembly after connection and assembly is completed is achieved. The assembly member 30 is used for assisting the connection assembly of the first connecting member 10 and the second connecting member 20, and the assembly member 30 drives the first connecting member 10 to move relative to the second connecting member 20 in the process of moving relative to the second connecting member 20 so as to complete the connection assembly process of the first connecting member 10 and the second connecting member 20; the fitting 30 remains free from disengagement with the second connector 20 during movement relative to the second connector 20.

In the above embodiment, the assembly member 30 is provided to assist in completing the connection and assembly of the first connection member 10 and the second connection member 20, and after the assembly is completed, even if people move away from the second connection member 20 by driving the assembly member 30, the connection relationship between the first connection member 10 and the second connection member 20 is not affected; further, since the force application structure for coupling and assembling the first coupling member 10 and the second coupling member 20 to each other is provided on the assembly member 30, the first coupling member 10 and the second coupling member 20 are not separated from each other even after the assembly member 30 is driven or the assembly member 30 is separated from the first coupling member 10 and the second coupling member 20 without knowing that the structure is a detachment prevention structure after the assembly. In the absence of the assembly member 30, the force points of the first connecting member 10 and the second connecting member 20 separating are on the first connecting member 10 and the second connecting member 20, and the separation process is more difficult due to the lack of corresponding force structures, so that people have no way to disassemble the first connecting member 10 and the second connecting member 20, and people can avoid accidentally destroying the anti-disassembling structures of the two connecting members through violence. On the other hand, in the process of moving the assembly member 30 to the second connection member 20, that is, in the process of driving the first connection member 10 to move to the second connection member 20 to complete the assembly action, the assembly member is kept from being separated from the second connection member 20, so that the assembly and connection process of the first connection member 10 and the second connection member 20 can be smoother, and the situation that the assembly member 10 and the second connection member 20 fall off when not connected in the assembly process and need to be repeatedly assembled is avoided, thereby improving the assembly efficiency.

In some of the embodiments, the fitting member 30 is coupled to the second coupling member 20 by a screw-fit connection, and in a specific example, the second coupling member 20 is provided with a first screw 202 on an outer surface thereof and the fitting member 30 is provided with a second screw 303 on an inner surface thereof, so that the fitting member 30 can be prevented from being disengaged from the second coupling member 20 during the movement of the fitting member 30 relative to the second coupling member 20, and the movement of the fitting member 30 relative to the second coupling member 20 can be achieved. The position of the thread arrangement may be different according to the specific shape and structure of the fitting member 30 and the second connecting member 20, for example, the surfaces of the fitting member 30 and the second connecting member 20 may be grooved, and the thread arrangement may be arranged in the groove, which is exemplified for clarity and is not limited to the specific position arrangement.

In other embodiments, the fitting 30 and the second connector 20 may be an interference fit, and movement of the fitting 30 relative to the second connector 20 may be achieved while maintaining the fitting 30 and the second connector 20 from disengaging. In other embodiments, a limiting structure may be provided on the assembly member 30 or the second connection member 20, or both of them, so that the assembly member 30 is kept from being separated from the second connection member 20 due to the limiting structure during the movement of the assembly member 30 relative to the second connection member 20.

In some embodiments, the inner surface of the first connecting element 10 is provided with a first locking portion 101, the outer surface of the second connecting element 20 is provided with a second locking portion 201, and the first locking portion 101 and the second locking portion 201 are matched with each other to limit the first connecting element 10 and the second connecting element 20 in the direction of separating from each other in the connection state, so that the purpose of preventing the first connecting element 10 and the second connecting element 20 from being detached in the connection state is achieved. It should be noted that, in the present embodiment, a connection relationship between the first connection element 10 and the second connection element 20 is provided, the outer surface of the first connection element 10 is provided with the second locking portion 201, and the inner surface of the second connection element 20 is provided with the first locking portion 101, and the technical means and manner thereof are the same, and they can also be considered as equivalent solutions to those proposed in the above embodiments.

In some embodiments, the first locking portion 101 and the second locking portion 201 are respectively a limiting protrusion and a limiting groove, and after the first connecting element 10 and the second connecting element 20 are connected, the limiting protrusion is clamped in the limiting groove, and at this time, the first connecting element 10 cannot be separated from the second connecting element 20, so as to achieve the anti-detachment function of the two. In a specific example, the first locking part 101 adopts a limiting protrusion, and the second locking part 201 adopts a limiting groove; in various examples, the first locking portion 101 employs a limiting groove, and the second locking portion 201 employs a limiting protrusion.

In other embodiments, the first locking portion 101 and the second locking portion 201 may also adopt an anti-rotation structure, that is, the first connecting element 10 and the second connecting element 20 can only rotate relatively in one direction, and during the rotation, the connection and assembly process of the two elements is completed, and then the anti-rotation is prevented, so as to achieve the anti-detachment function of the first connecting element 10 and the second connecting element 20.

In some embodiments, the first connecting element 10 is provided with a limiting portion on an outer surface, and the fitting 30 includes a fitting segment 301 and a driving segment 302. The assembly segment 301 is used for keeping the assembly member 30 and the second connecting piece 20 from being separated during the movement of the assembly member 30 relative to the second connecting piece 20; the driving section 302 contacts with the limiting portion to push the first connecting member 10 to move relative to the second connecting member 20, so as to drive the first connecting member 10 to move relative to the second connecting member 20 during the movement of the assembly member 30 relative to the second connecting member 20.

In a specific embodiment, the assembly member 30 is sleeved outside the first connection member 10, the outer surface of the first connection member 10 is provided with a limit protruding ring 102 as a limit portion, the inner diameter of the assembly section 301 is not smaller than the outer diameter of the limit protruding ring 102, and the inner diameter of the driving section 302 is smaller than the outer diameter of the limit protruding ring 102. During the process of driving the assembly member 30 to move relative to the second connecting member 20, because the inner diameter of the assembly section 301 is not smaller than the outer diameter of the limit convex ring 102, the assembly section 301 of the assembly member 30 can stride over the limit convex ring 102 to contact with the second connecting member 20, so as to keep the assembly member 30 from being separated from the second connecting member 20; the driving section 302 contacts the limit convex ring 102, and because the inner diameter of the driving section 302 is smaller than the outer diameter of the limit convex ring 102, the driving section 302 cannot stride over the limit convex ring 102, the limit convex ring 102 follows the assembly part 30 to move, and the first connecting part 10 follows the assembly part 30 to move relative to the second connecting part 20.

In some embodiments, the inner surface of the first connecting member 10 is provided with a sealing ring 40 for sealing the formed connecting structure when the first connecting member 10 and the second connecting member 20 are connected, which is applied to some mechanisms requiring sealing, such as sealing a pipeline. In various examples, the sealing ring 40 may also be provided on the second connector 20.

In a specific example, when the sealing ring 40 is disposed on the inner surface of the first connecting member 10, an annular groove is disposed on the inner surface of the first connecting member 10 for accommodating the sealing ring 40, so as to reduce the friction force of the first connecting member 10 in the connection state of the second connecting member 20, and avoid the situation that the assembly difficulty is increased due to the increase of the friction force of the first connecting member and the second connecting member due to the too much protrusion of the sealing ring 40.

In some of the embodiments, in the assembled state, the first connector 10 is provided with an opening on the side remote from the second connector 20 for connection with a pipe; the opening is arranged to be gradually increased inwards, and a sealing chamfer 103 can be formed in a connecting area of the opening and the pipeline so as to realize the sealing performance of the sealing mechanism. It should be noted that the second connecting member 20 may also be provided with an opening of the same shape on the side away from the first connecting member 10, and the opening may be specifically arranged according to a specific sealing scenario.

On the other hand, refrigerant materials such as R290 and R32 refrigerants are flammable and the leakage of the refrigerant is more strictly required in the air conditioner using the refrigerant, particularly, in the inner side of the air conditioner. In order to prevent leakage of refrigerant into the indoor side when a non-professional person removes the air conditioner without recovering the refrigerant. In the case of the existing disassembly-proof refrigerant pipe, an acting point for assembly exists at the joint position, and for non-professionals, the refrigerant material is in a leakage risk due to the fact that violent disassembly is carried out through the acting point.

The present embodiment provides a refrigerant pipe, including the joint of any one of the above embodiments, for preventing a non-professional person from violently detaching through an impact point during assembly.

In a specific example, when the refrigerant pipe is connected, the evaporator is butted with the connecting pipe, an adjustable wrench is used for assisting to rotate the assembly part 30, so as to realize screwing, the thread of the assembly part 30 is engaged with the thread of the second connecting piece 20, and the driving section of the assembly part 30 contacts the limiting convex ring 102 of the first connecting piece 10, so as to drive the first connecting piece 10 to be connected with the second connecting piece 20. Because the first connecting piece 10 and the second connecting piece 20 are locked by the locking part, even if the assembly member 30 is screwed out, the connection between the first connecting piece 10 and the second connecting piece 20 is not damaged, and then the sealing ring 40 and the sealing chamfer 103 are used for further sealing, thereby effectively preventing the leakage of the refrigerant. In the connected state, the assembly member 30 can also assist in pressing the connection area of the first connection member 10 and the second connection member 20, so as to prevent the second connection member 20 or the first connection member 10 from being enlarged when the first connection member 10 is inserted into the second connection member 20 or the second connection member 20 is inserted into the first connection member 10.

The joint, the refrigerant pipe and the air conditioner provided by the embodiment of the application are introduced in detail, a specific example is applied to explain the principle and the implementation mode of the application, and the description of the embodiment is only used for helping to understand the method and the core idea of the application; meanwhile, for those skilled in the art, according to the idea of the present application, there may be variations in the specific embodiments and the application scope, and in summary, the content of the present specification should not be construed as a limitation to the present application.
