Problems solved by technology

[0003] When existing air conditioners use pipe joints to connect indoor units and outdoor units, copper hexagonal nuts are often used as the connecting components of the pipe joints. Since the specifications of the nuts and supporting disassembly tools are not uniform, it is necessary to use different specifications for different specifications. The nuts are disassembled with the corresponding supporting tools, and because the supporting tools are often harder than the nuts, the nuts are easily damaged during the disassembly process

Embodiment 1

[0039] The invention provides a pipe joint, a disassembly tool and an air conditioner. Such as figure 1 As shown, the pipe joint of the present invention includes a single joint 1 and a nut 2, and the single joint 1 and the nut 2 are tightly fitted with each other. combine figure 2 and image 3 As shown, the single joint 1 includes a head 11 and a screw 12, the screw 12 is provided with an external thread 121, and the head 11 and the screw 12 are integrally formed in structure. The nut 2 includes a clamping portion 21, a slope portion 22 and a hollow portion 23, wherein the clamping portion 21 is cylindrical, the slope portion 22 is a truncated cone, and the slope 22 is a circular table with a large diameter. Connected with the circular surface of the clamping part 21, the clamping part 21 and the slope part 22 are integral in structure; the hollow part 23 is a hole-like structure, located in the middle hollow part of the nut 2, and the hollow part 23 Through the nut 2 in...

Embodiment 2

[0043] On the basis of Embodiment 1, this embodiment provides a dismounting tool 5 that is used in conjunction with the nut 2 described in Embodiment 1 above. combine Figure 6 As shown, the assembly and disassembly tool 5 of the present invention includes a buckling portion 51 and a handle 52 . The fastening part 51 includes a separation structure 511 and a locking protrusion 512. The separation structure 511 is arranged in the middle of the inner ring surface of the fastening part 51 of the dismounting tool 5. The separation structure 511 is an arc-shaped structure, and the locking protrusion 512 It is arranged on the inner ring surface of the fastening part 51; there are two fastening parts 51, and the two fastening parts 51 are respectively arranged at the two ends of the handle 52, and the fastening part 51 and the handle 52 are structurally integrally formed. The partition structure 511 is in the middle of the inner ring surface of the fastening part 51, and the partiti...

Embodiment 3

[0047] On the basis of Embodiment 1 and Embodiment 2, Embodiment 3 provides an air conditioner, combining Figure 9 As shown, the air conditioner includes an indoor unit connecting pipe 3 and an outdoor unit connecting pipe 4, and the indoor unit connecting pipe 3 and the outdoor unit connecting pipe 4 are connected through the pipe joint in the first embodiment. The single joint 1 of the pipe joint is connected with the connecting pipe 3 of the indoor unit, and the nut 2 is connected with the connecting pipe 4 of the outdoor unit. Commonly used air conditioners are divided into indoor units and outdoor units. When installing an air conditioner, the operator needs to connect the indoor unit to the outdoor unit through a connecting pipe, so as to realize the heat exchange between indoor and outdoor refrigerants, so as to achieve cooling or heating effects. Existing indoor units are generally provided with a single joint flowing out from the evaporator end when leaving the facto...

Abstract

The invention provides a pipe joint, a disassembly and assembly tool and an air conditioner, and relates to the technical field of the air conditioners. The pipe joint comprises a single joint and a cylindrical nut which can be fastened and matched with each other, and a clamping groove is formed in the outer side surface of the nut. The disassembly and assembly tool is used for disassembling andassembling the pipe joint. The air conditioner is connected with an indoor unit connecting pipe and an outdoor unit connecting pipe. The pipe joint is tightened up by being directly sleeved, the installation efficiency is improved, the shape surface of the nut is in a non-standard shape, deformation and failure of the nuts can be effectively avoided. The disassembly and assembly tool enters from the slope of the nut, and after the upper end of the disassembly and assembly tool is flush with the nut, a separation structure arranged limits the disassembly and assembly tool to continue moving upwards, so that the disassembly and assembly tool is more labor-saving in use.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to a pipe joint, a disassembly tool and an air conditioner. Background technique [0002] Commonly used air conditioners are divided into indoor units and outdoor units. Before use, users need to use connecting pipes to connect the indoor unit and the outdoor unit to achieve indoor and outdoor refrigerant heat exchange, and achieve cooling or heating effects through indoor and outdoor refrigerant heat exchange; indoor units When leaving the factory, a single joint flowing out from the evaporator end is generally provided, and the single joint is tightly matched with the pipe joint nut on the connecting pipe, and the other end of the connecting pipe is connected to the outdoor unit. [0003] When existing air conditioners use pipe joints to connect indoor units and outdoor units, copper hexagonal nuts are often used as the connecting components of the pipe joints. Since the ...
