Single line fire alarm line fixing clamp

Abstract

The invention discloses a single line fire alarm line fixing clamp which comprises a base, an upper pressing piece, a compression screw and a compression screw pin. The tail end of the base is hingedto the tail end of the upper pressing piece through a rotating shaft; after the upper pressing piece and the base are relatively overturned and buckled, an arc-shaped part of the base and an arc-shaped part of the upper pressing piece are buckled to form a hole; a cross hole is formed in the front end of the base; with respect to two strip holes perpendicular to each other in the cross hole, the width of one strip hole is larger than that of the other strip hole; a round hole is formed in the position of the upper pressing piece above the cross hole, and it is ensured that a rod body part of the compression screw can penetrate a center hole of the cross hole. According to the technical scheme, due to the fact that the length of the compression screw pin is greater than the diameter of theround hole of the upper pressing piece, the compression screw does not drop from the upper pressing piece, the upper pressing piece and the base are buckled, the compression screw is correspondingly rotated to make the compression screw pin correspond to the strip hole, with a larger width, of the cross hole of the base, the upper pressing piece continues to be pressed to make the compression screw pin penetrate the bottom of the cross hole, and rotation through 90 degrees is performed to complete locking.

Description

technical field [0001] The invention relates to a fixing device for a fire alarm wire in a fire alarm detection system on a helicopter engine, in particular to a single-wire fire alarm wire fixing clip. Background technique [0002] The fire alarm line fixing clamp is widely used in the fire alarm detection system of the engine in the aviation and aerospace industries, and plays a role in fastening and fixing the fire alarm line. In these industries, there are high requirements for product performance, high requirements for product material, strength, structure, weight, application and other performance, which cannot be replaced by other products. During the use of the traditional single-wire fire alarm wire fixing clamp, the locking method is bolt connection, which is heavy and troublesome. [0003] Traditional clamps can only be used in general areas, and the material strength is low, and the bending part of the clamp is easy to break, which cannot meet the aviation and a...

Problems solved by technology

[0003] Traditional clamps can only be used in general areas, and the material strength is low, and the bending part of the clamp is easy to break, which cannot meet the aviation and aerospace standards; the structure of the traditional clamp is simple, and the connection is easy to loose when it is vibrated, which may easily lead to product failure , and the bolts are easy to rust, and cannot be used in some special environments, and the installation is inconvenient
