Abstract
The invention discloses a pneumatic mechanism connecting pipe of an electrical device, which belongs to connecting pipes and is particularly applied to a CQ6-II mechanism used in an LW14(15)SF6 circuit breaker. The electrical device pneumatic mechanism connecting pipe comprises a pipe body and a connecting nut, wherein the connecting nut is sleeved on a joint part of both ends of the pipe body; and the pipe body is a corrugated metal pipe or a threaded metal pipe. By adopting the technical scheme, the corrugated metal pipe or the threaded metal pipe reduces the rigidity of the connecting pipe, the destructive power generated by the vibration of an air compressor can be effectively adsorbed uniformly, and the problem of easy breakage of the connecting pipe is solved. The invention has simple structure and convenient manufacture.
Description
Technical field
The present invention relates to a kind of connecting tube, specifically is a kind of Pneumatic mechanism connecting pipe of electrical device, is particularly suitable for the CQ6 at LW14 (15) type SF6 circuit breaker institute adapted---use in the II type pneumatic mechanism.
Background technique
The CQ6 of present LW14 (15) type SF6 circuit breaker institute adapted---in the II type mechanism, the used connecting tube of air compressor and gas receiver adopts the ordinary copper pipe to make, and it is strong that this kind connecting tube exists rigidity, and the anti-vibration performance is poor, problems such as easy-rupturing, so working life is short.
Summary of the invention
Too strong in order to overcome the rigidity that former connecting tube exists, problems such as anti-vibration performance difference and easy-rupturing the invention provides a kind of Pneumatic mechanism connecting pipe of electrical device.Can improve the working life of circuit breaker Pneumatic mechanism connecting pipe.
The present invention realizes with following technological scheme: a kind of Pneumatic mechanism connecting pipe of electrical device, comprise body and the coupling nut that is sleeved on the joint area of body two ends, and it is characterized in that body is corrugated metal pipe or screw thread metal pipe.
Owing to adopted technique scheme, the invention has the beneficial effects as follows: corrugated metal pipe or screw thread metal pipe have reduced the rigidity of connecting tube, can evenly absorb the collapsing force that the air compression machine vibration is produced effectively, have solved the problem of connecting tube easy-rupturing.And simple in structure, the convenient making.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Accompanying drawing is a structural representation of the present invention.
Among the figure: 1, coupling nut, 2, body, 3, joint area.
Embodiment
As shown in drawings, Pneumatic mechanism connecting pipe of electrical device is made up of body 2 and the coupling nut 1 that is sleeved on the body two ends joint area 3, and body 2 is corrugated metal pipes, also can be screw thread metal pipe.The global shape of body 2 is made into bend pipe or straight tube as required.Connecting tube has adopted 12 millimeters thread-shaped copper tubes of diameter to make in the present embodiment, have rigidity moderate, can absorb vibration effectively equably from external force, avoided stress to concentrate, prevent metal fatigue, improved working life.
