Problems solved by technology

[0003] (1) When another staff member assists to pull the screen cabinet door or the person working in the screen cabinet blocks the screen cabinet door by himself, the work efficiency will be reduced
[0004] (2) Since the secondary circuit on the switch cabinet is live, when the staff is holding the door of the screen cabinet while working, they may mistakenly touch the live equipment, resulting in an electric shock accident
[0005] (3) When other staff accidentally touch the door of the screen cabinet, it may squeeze the personnel working in the screen cabinet, thus posing a threat to the personal safety of the relay protection personnel working in the screen cabinet

Abstract

The invention relates to a special small door retaining bolt for preventing mistaken shutdown of a cabinet door, which comprises a plurality of clamping components and support components. The clamping components are respectively arranged at the two ends of the support components and comprise a clamping port, a wing-shaped nut component and a groove respectively, the clamping ports are U-shaped, the wing-shaped nut components are arranged on the clamping ports, and the grooves are arranged on the arc-shaped bottoms of the clamping ports. The wing-shaped nut components comprise a wing-shaped clamping port nut, a spring washer, a clamping port washer and a clamping port threaded rod respectively, the clamping port threaded rods are arranged on one side edges of the clamping ports, the wing-shaped clamping port nuts are arranged at one ends of the clamping port threaded rods and outside the side edges of the clamping ports, and the spring washers are arranged between the wing-shaped clamping port nuts and the outer side edges of the clamping ports. By adopting the small door retaining bolt, the cabinet door can be reliably prevented from being mistakenly shut down. Moreover, the small door retaining bolt can be used conveniently, the opening degree of the cabinet door can be adjusted, and no extrusion can be caused to personnel behind the cabinet door when the cabinet door is mistakenly touched.

Description

technical field [0001] The invention relates to a stopper, in particular to a special small door stopper for preventing cabinet doors from being closed by mistake. Background technique [0002] In the daily work of relay protection, relay protection personnel often need to work on the relay protection panel and protection screen (such as watt-hour meter screen, grounding detection screen, communication screen, etc.) on the switch cabinet. When working in these two screen cabinets, the screen cabinet door must be opened, but the screen cabinet door tends to close due to mechanical stress, and there is a situation that the screen cabinet door will touch the body of the staff, which brings hidden dangers to safe production. Aiming at the phenomenon that the screen cabinet door is closed by mistake, the following methods are generally adopted at present: other staff members assist to pull the opened cabinet door, or the personnel working in the screen cabinet block the screen ca...
