Description

Screw-free mounting corrugated pipe quick-insertion type fixing head

Technical Field

The utility model relates to the technical field of corrugated pipes, in particular to a screw-free mounting corrugated pipe quick-insertion type fixing head.

Background

The corrugated pipe is a tubular elastic sensing element formed by connecting foldable corrugated sheets along the folding and stretching directions. The bellows is widely used in instruments and meters, and is mainly used as a measuring element of a pressure measuring instrument to convert pressure into displacement or force. The corrugated pipe has thinner pipe wall and higher sensitivity, and the measuring range is tens of Pa to tens of megaPa. The open end is fixed, the sealed end is in a free state, and the elasticity is increased by using an auxiliary spiral spring or reed. When in operation, the movable end is stretched along the length direction of the pipe under the action of internal pressure, so that the movable end generates displacement in a certain relation with the pressure. The movable end drives the pointer to directly indicate the pressure. Bellows often in combination with displacement sensors constitute a pressure sensor that outputs an electrical quantity, sometimes also serving as an isolating element.

At present, when the corrugated pipe is installed and connected, the traditional quick-connection joint needs to be screwed at the bottom of the screw thread and externally screwed by the screw nut for rotation and fastening, and sometimes the distance of the joint is limited, the joint cannot be screwed inwards, and the connection is unstable.
