Description

Pulling force adjustable release

Technical Field

The utility model relates to a pulling force adjustable release.

Background

The leakage release is a release for controlling breaking by detecting residual current, and is divided into a normally open type and a normally closed type according to a normal working state, and the normally closed leakage release is usually realized by adopting a permanent magnet. The existing normally closed leakage tripping device does not have the function of adjusting the elasticity of a spring generally, and is difficult to solve the problem that stable normally closing cannot be realized due to different magnetic forces of different magnets. Therefore, the development of a tension-adjustable release with small volume, stable and reliable performance is urgently needed.

Disclosure of Invention

In view of this, the utility model aims at providing a compact structure adjusts convenient pulling force adjustable release.

In order to realize above purpose, the utility model discloses a pulling force adjustable release, including the yoke, armature, the coil, the movable reed, a spring, adjusting screw, the yoke passes the coil, yoke one end upwards extends, armature articulates on the yoke top, the movable reed front end is connected to the side on armature, the middle section of movable reed upwards perks and unsettled formation free portion, the adjustment tank has been seted up at the center of free portion, the end of free portion forms stores pylon on the spring, armature corresponds adjustment tank formation screw hole, adjusting screw wears in the screw hole, adjusting screw's nut is pressed on the movable reed free portion of adjustment tank both sides, form stores pylon under the spring on the yoke, spring coupling is under stores pylon and the spring on the spring between the stores pylon.

The utility model discloses further set up as the yoke is including moving yoke and quiet yoke, and the outside of moving the yoke upwards extends and articulated armature, moves in the crisscross insert coil of each other of the inner of yoke and quiet yoke, and quiet yoke setting is moving the yoke downside, and the coil is worn out at the inner top of quiet yoke and is extended to and move the yoke outside and form stores pylon under the spring, and the spring lower extreme is hung under the spring on the stores pylon.

The utility model has the advantages that the armature iron is connected with the adjusting screw, and the tilting movable reed suspension part is pushed to move up and down through the screw cap of the adjusting screw when the armature iron is screwed out and screwed in, so as to drive the distance between the upper spring hanging rack at the tail end of the suspension part and the lower spring hanging rack, and realize the purpose of adjusting the tension of the spring; and the spring lower hanging rack is formed by molding the top ends of the yokes, particularly the static yokes, so that an additional assembling process is not needed, the production and the assembly are convenient, and the automatic production is convenient to realize.
