Self-tightening pipe clamp and air conditioner using it

Abstract

The present invention provides a self-tightening pipe clamp, comprising at least one pair of clamp bodies, the pair of clamp bodies includes a first clamp body and a second clamp body, and it is characterized in that one end of the first clamp body and the second clamp body passes through The rotating shaft is rotatably connected, and a return spring is arranged on the rotating shaft, and one end of the returning spring is connected with a thimble that passes through the first clamp body from the outer surface of the first clamp body and extends into the inside of the first clamp body, and the other end abuts against the first clamp body. For the second clip body, when the thimble is pressed inwardly into the first clip body, the return spring pushes the first clip body and the second clip body to close. The self-tightening pipe clamp proposed by the present invention, while ensuring no extrusion and friction between the pipelines, adopts the fastening method of spring thimble triggering combined with plugging and clipping, which effectively improves the reliability of pipeline fastening, without It is fastened with screws or wire ties, which is convenient for disassembly and assembly, and reduces the work intensity of production and after-sales installers; it can still be fastened in a pipeline system with a certain deviation, meeting the higher assembly requirements of the assembly line for lean production.

Description

technical field [0001] The invention relates to the technical field of fixing air-conditioning pipelines, and more specifically relates to a self-tightening pipe clamp and an air conditioner using the same. Background technique [0002] Patent No. CN201610952024.6 discloses a self-locking pipe clamp and an air conditioner using it, but this pipe clamp must pass through the clamping arm, and the clamping arm must be opened to meet the diameter of the installation pipeline. Loosen the clamping arm to restore it to its natural position, and then insert the protrusion into the groove to complete the pipeline fixation. The whole process is complicated and the alignment operation is troublesome. Two protrusions must be inserted into the groove synchronously. However, it does not mean "automatic locking and automatic assembly" in the true sense. After the butt joint, the interference fit between the pipeline and the through hole of the pipe clamp will bring certain difficulties to ...

AI Technical Summary

Problems solved by technology

[0004] In the current technology, in order to clamp the pipeline and maintain the stable state of the clamp, the clamp usually needs to be used with a wire tie. It falls off during vibration. After the clamping is completed, use diagonal pliers to cut off the excess wire tie. The high-temperature wire tie is easy to age and break after long-term use. Other pipe clamping methods include screw fastening and the above two patent methods, which still need to be manually clamped. It is inconvenient to snap in the buckle. In addition, the reference of the above-mentioned clamping rotating part is located on one side of the device, and the cumulative assembly error will increase away from the rotating part. Easy to trip when the road has a certain deviation
