Fixing device for undervoltage protector

Abstract

The invention provides a fixing device for an undervoltage protector, which includes a card base body and a guide rail. The card base body is provided with a clamping mechanism. There are several through holes on the body, and each through hole is provided with a pin rod and communicates with the gear chamber. The gear chamber is respectively provided with a first bevel gear and two second bevel gears. One end of the pin rod is rotatably connected to the card holder body The top of the top, the other end is fixedly connected to the first bevel gear, and the two second bevel gears are symmetrically meshed on both sides of the first bevel gear, and the axis of the first bevel gear and the second bevel gear The axis of the shaft is vertical, and the two clamping cavities are symmetrically arranged on both sides of the gear cavity, facing away from each other. Each second bevel gear is vertically fixedly connected to one end of the threaded rod, and the other end of the threaded rod extends into the clamping cavity and connects to the resisting cavity in the cavity. pick up. The fixing device of the invention is simple in structure, stable and reliable, greatly saves time, and improves clamping efficiency.

Description

technical field [0001] The invention relates to the field of electrical equipment accessories, in particular to a fixing device for an undervoltage protector. Background technique [0002] The existing box fixing devices are generally snapped on the guide rails, and the guide rails are provided in the box, and are snapped on the guide rails with an integrated device. However, this kind of fixing device cannot be used in some specific positions. , and the fixing device also has unreliable clamping. [0003] Due to different site environments, sometimes it is necessary to use different types of undervoltage protectors, and sometimes they need to be used in combination. Since there is no fixation between adjacent undervoltage protectors, it is very difficult to It is easy to cause the overvoltage and undervoltage protector to slide or fall off, causing the undervoltage protector to deviate from its original position. In addition, it is easy to cause deformation of the wire of...

[0002] The existing box fixing devices are generally snapped on the guide rails, and the guide rails are provided in the box, and are snapped on the guide rails with an integrated device. However, this kind of fixing device cannot be used in some specific positions. , and the fixing device also has the situation that the clamping is not secure

[0003] Due to different site environments, sometimes it is necessary to use different types of undervoltage protectors, and sometimes they need to be used in combination. Since there is no fixation between adjacent undervoltage protectors, it is very difficult to It is easy to cause the overvoltage protector to slide or fall off, making the undervoltage protector deviate from the original position

In addition, it is easy to cause deformation of the wire of the undervoltage protector, and even cause the wire to fall off, and the adjacent undervoltage protector is not fixed, and the installation and removal are very cumbersome
