Embodiment 1

[0021] This embodiment provides a floating self-adjusting pull-out structure for a mine explosion-proof box, such as figure 1 and figure 2 shown, including:

[0022] The slide rails 1 installed on both sides inside the explosion-proof box, the supporting plate 6 installed inside the explosion-proof box for pulling, and the "┑"-shaped fixing ear 5, one side of the supporting plate 6 is installed with the "┑"-shaped Fixed ear 5, the other side of the pallet 6 is slidably installed with the slide rail 1 on the corresponding side of the explosion-proof box;

[0023] One end of the "┑"-shaped fixed ear 5 is installed under the supporting plate 6, and is floatingly connected with the supporting plate 6; the other end of the "┑"-shaped fixed ear 5 is connected to the corresponding side of the explosion-proof box. The above-mentioned slide rail 1 is slidably installed.

[0024] In this embodiment, the slide rails 1 on both sides of the explosion-proof box are respectively fastened...

Embodiment 2

[0037] This embodiment provides a mine explosion-proof box, such as figure 1 As shown, the drawing structure described in Embodiment 1 is included.

[0038] For the drawing structure of this embodiment, please refer to Example 1. Through the drawing structure described in Example 1, during the installation process of the slide rail, there is no need to repeatedly adjust the slide rail to be parallel to the left and right and to be parallel to the top and bottom. The installation is convenient, time-saving and labor-saving .

Abstract

This application relates to a floating self-adjusting pull-out structure for a mine explosion-proof box, including slide rails installed on both sides inside the explosion-proof box, and a supporting plate installed inside the explosion-proof box for pulling, and also includes "┑" The "┑"-shaped fixing ear is installed on one side of the supporting plate, and the other side of the supporting plate is fixedly installed with the slide rail on the corresponding side of the explosion-proof box; the "┑"-shaped One end of the fixed ear is installed under the supporting plate and is connected to the supporting plate in a floating manner; the other end of the “┑”-shaped fixed ear is fixedly installed with the slide rail on the corresponding side of the explosion-proof box. The supporting plate of the present invention can automatically adjust the height and angle during the drawing process, always maintain the parallelism of both sides of the supporting plate, and solve the problem of difficult drawing in the existing drawing structure.

Description

technical field [0001] The application belongs to the technical field of explosion-proof boxes for mines, and in particular relates to a floating self-adjusting drawing structure for explosion-proof boxes for mines and the explosion-proof box for mines. Background technique [0002] With the improvement of automation in coal mining, the degree of centralized control of explosion-proof electrical equipment used in coal mines is getting higher and higher. Explosion-proof boxes for mines are suitable for coal mines containing gas and coal dust. In the power supply system, they are used as the main switch or branch switch of the power supply system to distribute electric energy and control the undervoltage, overload, short circuit, and disconnection of power supply equipment and lines. Phase and leakage and other faults are protected. The core is the core component of the feed switch. During the installation and maintenance of the electric control cabinet, it is often necessary...
