Embodiment Construction

[0017] The patent of the present invention will be described in further detail below in conjunction with the accompanying drawings of the description, please refer to the attached description figure 2 , 3 , 4.

[0018] The square air-conditioning pipeline on the existing aircraft is fastened by bolts 10, washers 11, and nuts 12, such as figure 1 As shown, dozens or hundreds of bolts, washers, and nuts are required to realize the installation, and the processing technology requirements are very high. The tolerance of the installation holes must be controlled very strictly to ensure that the bolts can be completely screwed in. In this installation method, the dimensional tolerance is difficult to control, and the workmanship is poor; the accessibility is very poor, and disassembly and assembly are very inconvenient, time-consuming and laborious.

[0019] The patent of the present invention provides a quick-release clamp for connecting square pipelines of aircraft, including: ...

Abstract

The invention relates to an air conditioner pipeline square flange connection quick-release clamp which comprises a strap 4, a bolt 5, a sleeve pipe 6, a gasket 7, a nut 8 and a clamping ring 9. The two ends of the strap 4 are connected with the sleeve pipe 6 and the bolt 5 in a spot welding mode, the strap 4 is formed by bending a metal straight plate, flanging the two ends and carrying out welding and fixing, the sleeve pipe 6 is inserted into one side of the strap 4 to be flanged and turned, the bolt 5 is inserted into the other side of the strap 4 to be flanged and turned, the straps 4 hoops the clamping ring 9, the clamping ring 9 and the strap 4 are subjected to spot welding in the circumferential direction, the bolt 5 is inserted into the sleeve pipe 6, and the portion, penetratingthrough the sleeve pipe 6, of the bolt 5 is sleeved with the gasket 7 and screwed through the nut 8. After the novel method is adopted for quickly releasing the clamp, the pipeline installation and maintenance process is quite convenient, rapid connection and release can be easily achieved by means of a conventional spanner since the square quick-release clamp is provided with only one to two bolts, and the airplane using and maintenance workload is greatly relieved.

Description

technical field [0001] The invention relates to a quick-release clamp used for connecting a square pipeline of an aircraft. Background technique [0002] The connection structure of the existing aircraft square pipeline is as attached to the instruction manual figure 1 As shown, the pipelines are connected through bulky flange joints, and a bolt hole is punched at intervals on the flange surface, and fastened by bolts 10, washers 11, and nuts 12, usually dozens or hundreds of bolts, Only washers and nuts can be installed, and the processing technology requirements are very high. The tolerance of the installation holes must be controlled very strictly to ensure that the bolts can be completely screwed in. In this installation method, the dimensional tolerance is difficult to control, and the workmanship is poor; the accessibility is very poor, and disassembly and assembly are very inconvenient, time-consuming and laborious. Contents of the invention [0003] The purpose o...
