Spring bolt guiding device for switch cabinet

Abstract

The invention relates to a spring bolt guiding device for a switch cabinet. A spring bolt limiting plate is mounted in a position, corresponding to a door lock of a cabinet door, on a column of the open side of the cabinet door of the switch cabinet; the spring bolt limiting plate is a Z-shaped plate formed by primarily forming a metal panel by means of malposed bending; a positioning section is fixedly connected to the column of the switch cabinet through threaded connection; a spring bolt limiting groove in the middle of the limiting section can guide the spring bolt of the door lock; when the cabinet door of the switch cabinet is closed and the spring bolt rotates along a lock shaft and stretches into the limiting groove, the vertical angle part of the spring bolt of the spring bolt limiting plate enters a guide slot structure, the width of which is greater than that of the middle section of the limiting groove first, so that position and dimension errors can be met; the spring boltrotates continuously around the lock shaft, and the spring bolt gradually enters the middle section of the limiting groove along the guide slot to lock the cabinet door fully, so that the spring boltguiding device is convenient to operate; and the spring bolt limiting plate is matched with a door lock baffle plate through the extended section to shield the spring bolt and components in the switch cabinet, so that the failure rate is reduced, and the safety coefficient is improved; and the it is convenient and reliable to lock the cabinet door.
