In this embodiment, the first connection pipe 100 may be an aluminum pipe, a copper pipe, a stainless steel pipe or a pipe made of other materials, so that the first connection ring 200 may be suitable for connection pipes made of various materials, thereby expanding the application range of the air-conditioning connection pipe 1 in this embodiment. The first connecting piece is in particular a threaded joint.

Wherein, the first connecting pipe 100 is located to the first connecting ring 200 cover, because the first spacing arch 210 that the first connecting ring 200 was equipped with, when the first end 110 of first connecting pipe 100 and first mounting 300 were assembled, first spacing arch 210 just can support the inner wall that leans on first fitting space 310, through the setting of first spacing arch 210, thereby filled the space that first connecting pipe 100 single connection first mounting 300 can produce, thereby improved the leakproofness that first connecting pipe 100 and first mounting 300 are connected, further prevented that the refrigerant from revealing. Meanwhile, in the related art, the horn mouth needs to be formed in advance on the first connecting pipe 100, and the forming of the horn mouth needs a special tool and a professional, which wastes time and labor, and the production cost is high, so that the first connecting pipe 100 is sleeved with the first connecting ring 200 to be connected with the first fixing member 300 through the embodiment, so that the horn mouth does not need to be formed on the first connecting pipe 100, time and labor are saved, the production and manufacturing cost can be reduced to a certain extent, and the problem of forming deviation of the horn mouth does not exist.

Further, the first connection ring 200 is made of an elastic material. Specifically, the first link ring 200 is a highly elastic material having reversible deformation. Preferably, the first connecting ring 200 in this embodiment is made of a rubber material. Therefore, the first connection ring 200 is conveniently sleeved on the first end 110 of the first connection pipe 100, and meanwhile, the first connection ring 200 can be conveniently detached from the first end 110 of the first connection pipe 100, so that the first connection ring 200 can be conveniently replaced.

The first fixing member 300 includes: a recess 320, the recess 320 being provided in the first fitting space 310; when the first connection ring 200 is inserted into the first fitting space 310, the first position-limiting protrusion 210 is engaged with the recess 320. The recess 320 is embodied as an internal thread structure of the first fixing member 300 located in the first assembling space 310.

The first stopper protrusion 210 includes: a leading tooth surface 211; an engaging tooth surface 212, the guide tooth surface 211 abutting against the engaging tooth surface 212, and the guide tooth surface 211 opposing the engaging tooth surface 212; when the first connecting ring 200 is fitted in the first fitting space 310, the engaging tooth surface 212 abuts against the recess 320 to stop the first connecting ring 200 from coming out of the first fitting space 310.

The first limiting protrusion 210 is a hard tooth-shaped structure, and specifically, the hard tooth-shaped structure is composed of a guiding tooth surface 211 and an engaging tooth surface 212, as shown in fig. 2 and 4, the length of the guiding tooth surface 211 is longer than that of the engaging tooth surface 212, and an included angle formed between the guiding tooth surface 211 and the surface of the first connecting ring 200 is smaller than that formed between the engaging tooth surface 212 and the surface of the first connecting ring 200, that is, the guiding tooth surface 211 is inclined at a small angle, so that the guiding tooth surface 211 has a certain guiding function, the first connecting ring 200 can conveniently enter the first assembling space 310, and the first limiting protrusion 210 can be conveniently matched with the recess 320. The engaging tooth surface 212 is inclined at a large angle, so that after the first connecting ring 200 enters the first assembling space 310, the engaging tooth surface 212 can abut against a large-angle inclined surface which is also arranged on the concave portion 320, that is, when an operator forcibly pulls the first connecting pipe 100 with the first connecting ring 200 along the axial direction of the hole of the first assembling space 310 by hand, the surface tooth structure of the first limiting protrusion 210 is blocked by the surface tooth structure of the internal thread structure, so that the first connecting pipe 100 is difficult to pull out from the first assembling space 310, and the disassembly can be achieved only by means of a special tool, thereby preventing the user from disassembling by himself.

Further, due to the elastic deformation property of the first connection ring 200, the operator may forcibly press the first connection pipe 100, on which the first connection ring 200 is mounted, toward the first fitting space 310 by hand, that is, axially press the first connection pipe 100 along the hole of the first fitting space 310, and then guide the first connection ring 200 into the first fitting space 310 through the guide tooth surface 211 provided to the first stopper protrusion 210. The first end 110 of the first connection pipe 100, on which the first connection ring 200 is fitted, is smoothly inserted into the first fitting space 310 until the first stopper protrusion 210 completely enters the first fitting space 310, i.e., the first stopper protrusion 210 stops the first connection pipe 100 from penetrating without being exposed.

Wherein, when the first connection pipe 100 with the first connection ring 200 is connected to the first fixing member 300, the first restriction protrusion 210 of the first connection ring 200 at the connection point is completely engaged with the recess 320 of the first fitting space 310.
