Embodiment 1

[0042] like Figure 1-9 As shown, a disassembly-resistant connector includes a connector body 4 and auxiliary tooling 2 .

[0043] like Figure 4 As shown, the connector body 4 is provided with a threaded hole 41 and a slot 42; specifically, the connector body 4 is cylindrical, and one end of the connector body 4 is provided with a gradually narrowing bell mouth, thereby connecting with the bell mouth The pipe 5 communicates; wherein, the threaded hole 41 is provided through the axis of the connector, so that the threaded hole 41 can be screwed with the pipe joint 3 to realize assembly; the slot 42 is arranged along the axis of the connector body 4, thereby , the slot 42 is convenient to cooperate with the auxiliary tooling 2 to realize assembly.

[0044] In this embodiment, the outer edge of the connector body 4 does not match the screwing tool such as a wrench. Therefore, the screwing tool such as a wrench cannot be used to rotate the connector body 4 , and the auxiliary t...

Embodiment 2

[0051]Compared with the above-mentioned embodiments, this embodiment differs in that the auxiliary tooling 2 in this embodiment includes a first end face 22, a second end face 23, a third end face 24, a fourth end face 25 and a fifth end face 26; wherein , the first end surface 22, the second end surface 23, the third end surface 24, the fourth end surface 25 and the fifth end surface 26 are sequentially connected to form the engaging cavity 21, specifically, the angle between the five is 120 degrees, thus, it is convenient Cooperate with a tightening tool such as a wrench; the first end surface 22 and the fifth end surface 26 are disconnected to form a notch 212 , thus, under the action of the notch 212 , the assembly and disassembly of the auxiliary tooling 2 and the connector body 4 are realized.

[0052] In this embodiment, the first end face 22 and the fourth end face 25 form a first anti-disassembly structure; when the auxiliary tooling 2 reduces the torque transmission e...

Embodiment 3

[0055] Compared with the above-mentioned embodiments, this embodiment differs in that the engaging cavity 21 in this embodiment is provided with a surrounding edge 213; when the engaging cavity 21 fits on the connector body 4, the surrounding edge 213 abuts against the connecting head body 4. Specifically, one end of the engaging cavity 21 is provided with a surrounding edge 213, and the surrounding edge 213 and the block 211 are perpendicular to each other, thus, under the action of the surrounding edge 213, the position of the auxiliary tooling 2 on the connector body 4 can be positioned. position to prevent the auxiliary tooling 2 from sliding down along the outer edge of the connector body 4 .

Abstract

The invention provides an anti-disassembly connector, a connector assembly and an air conditioner. The anti-disassembly connector comprises a connector body and an auxiliary tool. The connector body is provided with a threaded hole and an open groove. The auxiliary tool is provided with a clamping cavity, and the clamping cavity is provided with a notch and clamping blocks. The connector body is detachably sleeved with the clamping cavity of the auxiliary tool in a matched mode through the notch, and the clamping blocks of the auxiliary tool are located in the open groove of the connector body. The open groove includes a tightening surface and a disassembling surface. When the tightening torque is applied to the auxiliary tool, the auxiliary tool applies the torque to the connector body through the tightening surface to drive the connector body to rotate; and when the loosening torque is applied to the auxiliary tool, the auxiliary tool reduces the torque transmission efficiency through the disassembling surface, the auxiliary tool deforms or a torque tool acting on the auxiliary tool is forced to slip, and the connector body cannot be driven to rotate.

Description

technical field [0001] The invention relates to the technical field of pipe connection structures and air conditioners, in particular to an anti-disassembly joint, a joint assembly and an air conditioner. Background technique [0002] At present, the air conditioner uses pipe joints and joints to connect the evaporator and the connecting pipe. However, it is required in the GB4706.32-2012 standard that reusable mechanical connection joints and bell mouth interfaces are not allowed to be placed in the indoor part of the air conditioner. Existing connectors are generally one-piece, which mainly consists of two parts: a threaded section and a prism surface section. When a clockwise torque is applied to the prism surface section, the thread section and the prism surface section rotate together to closely match the pipe joint. ; However, when a counterclockwise torque is applied to the prism surface section, it also drives the threaded section to rotate together, so the fit with...
