Example Embodiment

[0021] The present invention will be further described below in conjunction with the embodiments in the drawings:

[0022] Such as Figure 1~4 As shown, the present invention mainly includes a telescopic pipe body 2 capable of axial expansion and contraction and pipe joints 1 connected to both ends of the telescopic pipe body 2.

[0023] The telescopic pipe body 2 includes a plurality of branch pipe bodies 3, which are connected end to end in turn into one body, and the distance between each two branch pipe bodies 3 can be adjusted axially.

[0024] Such as image 3 As shown, the branch body 3 includes a head tube body 4 and a tail tube body 5 that are connected back and forth. The outer surface of the head tube body 4 is provided with a plurality of ring-shaped external head engaging teeth 6, a plurality of The external bite teeth 6 of the head are evenly distributed along the length direction. The inner surface of the head tube body 4 is provided with a plurality of ring-shaped i...

Abstract

The invention relates to a ventilation pipe, in particular to a linear profile winding type ventilation pipe, and belongs to the technical field of moving type industrial cold air machines. The ventilation pipe comprises a telescopic pipe body and pipe joints connected to the two ends of the telescopic pipe body, a head pipe body of the back branch pipe body in two adjacent branch pipe bodies of the telescopic pipe body stretches into a mounting cavity of a tail pipe body of the front branch pipe body, head inner meshing teeth of the head pipe body and tail inner ring meshing teeth of the tailpipe body are in meshed connection, and head outer meshing teeth of the head pipe body and tail outer ring meshing teeth of the tail pipe body are in meshed connection. The ventilation pipe is simple, compact and reasonable in structure, the branch pipe bodies are in telescopic connection through the meshing teeth, and are prevented from front and back falling through positioning teeth, during use, good positioning, orienting and ventilating effects are achieved, forming is easy and convenient, and cost is low.

Description

technical field [0001] The invention relates to a ventilating pipe, in particular to a coiled linear profile ventilating pipe, which belongs to the technical field of mobile industrial air conditioners. Background technique [0002] In the prior art, molded and sized corrugated pipes are generally used for air supply and exhaust pipes used in equipment such as household appliances, medical treatment, and industrial and mining equipment. This kind of bellows is soft in nature and cannot be positioned or oriented. It has poor manufacturability when used or manufactured, high cost, and difficulties in forming and connecting. Especially in mobile industrial air conditioner equipment, it must be bent, self-positioning and deflecting out of the wind. The directions are difficult and cause inconvenience in use. Contents of the invention [0003] The purpose of the present invention is to overcome the above disadvantages, thereby providing a linear profile winding ventilation pip...
