Low-voltage switchgear drawer position interlocking mechanism

Abstract

The invention relates to a drawer position interlocking mechanism of a low-voltage switch cabinet. The drawer position interlocking mechanism comprises loop compartments provided with compartment laminating plates. Each loop compartment is correspondingly provided with a drawer; each drawer is divided into a main drawer body and an electrical element module assembly; the main drawer body can be vertically and slidably provided with a spring bolt block; and lock holes are correspondingly formed in the compartment laminating plates. A swing plate is installed at the main drawer body in a horizontal swing manner; the electrical element module assemblies are fixedly connected with inclined plates; and vertical pins of the swing plates abut against edges of sides of the inclined plates. A capsule-shaped lock cylinder block is arranged between the swing plate and the spring bolt block; an arc section is formed at the edge of one side, being close to the capsule-shaped lock cylinder block, ofthe swing plate; an arc notch is formed in the middle of the arc section of the swing plate; and an arc groove in which a hemispherical end part of the capsule-shaped lock cylinder block is embeddedis formed in the side surface, facing the capsule-shaped lock cylinder block, of the lock spring block. Therefore, a phenomenon that a drawer in a testing state or working state is drawn out of the loop compartment accidentally is prevented.

Description

technical field [0001] The invention belongs to the technical field of power switch cabinets, and in particular relates to a drawer position interlocking mechanism of a low-voltage switch cabinet. Background technique [0002] The low-voltage switchgear can be designed as a drawer type, such as figure 1 , figure 2 , image 3 As shown, it includes a plurality of circuit compartments 1, and the circuit compartment 1 is provided with a compartment laminate 11, and each circuit compartment 1 is correspondingly equipped with a drawer 2, and the drawer 2 is located above the corresponding compartment laminate 11, and the drawer 2 Driven by the screw mechanism to produce longitudinal movement; the front (front) of the drawer 2 is provided with a drawer panel 210, and the rear end of the drawer 2 is provided with a plug-in 220. The plug-in is divided into a primary plug-in and a secondary plug-in, and the rear end of the circuit compartment corresponds to There are primary socke...

AI Technical Summary

Problems solved by technology

[0006] Although the above-mentioned drawer structure solves the problem of the gap between the drawer panel and the circuit compartment frame, there are still the following problems: when the drawer is in the test state (test position) or working state (working position), in the case of misoperation, It is still possible to accidentally pull the entire drawer (including drawer body and electrical component module assembly) out by pulling on the drawer front

In other words, the above-mentioned drawers lack a reliable mechanical interlocking structure, which cannot prevent the drawers from being accidentally pulled out in the test state or working state, so there are still potential safety hazards
