Self-fixing slide rail type switch cabinet based on special-shaped lever transmission principle

Abstract

The invention relates to the technical field of power. The invention further discloses a self-fixing sliding rail type switch cabinet based on the special-shaped lever transmission principle. The switch cabinet comprises a cabinet body; a cabinet door is hinged to the exterior of the cabinet body; the interior of the cabinet body is fixedly connected with a fixed guide rail; the exterior of the cabinet door is fixedly connected with a movable guide rail; an arc-shaped telescopic rod is hinged to the interior of the movable guide rail; a connecting piece is fixedly connected with the outer partof the arc-shaped telescopic rod; the fixed guide rail, the movable guide rail and the cabinet door are matched for use; a pull rod is hinged between the cabinet door and the cabinet body; the stability of a mounting frame in the moving process is fully ensured; through supporting of the cabinet door, the mounting frame is stressed uniformly and is stable in structure in the moving process between the fixed guide rail and the movable guide rail, so that the phenomena of jamming or derailing and the like caused by damage of the fixed guide rail, the movable guide rail and a guide wheel due touneven stress are avoided; smooth production of work is effectively guaranteed; and the working efficiency is guaranteed.

Description

technical field [0001] The invention relates to the field of electric power technology, in particular to a self-fixing slide rail switch cabinet based on the transmission principle of a special-shaped lever. Background technique [0002] The drawer-type switchgear is made of steel plate to make a closed shell. The electrical components of the incoming and outgoing circuit circuits are all installed in drawers that can be drawn out to form a functional unit that can complete a certain type of power supply task. Between the functional unit and the busbar or cable, use grounding. The metal plate or plastic functional plate is separated to form three areas of busbar, functional unit and cable. There are also isolation measures between each functional unit. The drawer type switchgear has high reliability, safety and interchangeability. It is a relatively advanced switchgear. Most of the switchgears produced are drawer-type switchgears. They are suitable for industrial and mining ...

Problems solved by technology

[0003] However, the existing switchgear adopts drawer type pull-in and pull-out, and its guide rails are usually arranged on both sides of the inner wall of the cabinet, and the pulleys of the drawer are movably connected on the guide rails to move. When the drawer with power components is pulled out, the bottom of the drawer is often in a suspended state, and the power components and the drawer themselves have a certain quality, and due to the principle of leverage, they put a lot of pressure on the internal pulleys and slide rails, which is easy to cause The structure is unstable, causing damage to the internal slide rails, resulting in derailment of the guide rails, etc., causing the drawer to be stuck inside, or causing the drawer to fail to slide into the cabinet smoothly, thus affecting the work efficiency of the staff for power installation or power maintenance As a result, the work cannot be carried out smoothly, and the existing switchgear is often not equipped with fixing measures when it is pulled out, so that the staff may easily cause the drawer to move when they are working, which will affect the staff's installation or maintenance operations. Very inconvenient to operate, affecting work efficiency
