The second type is a slide rail type drawing structure, as shown in fig. 2, two steel ball slide rails are respectively fixed on two sides of the enclosing plate of the explosion-proof box, and two sides of the supporting plate are respectively fixed with the two steel ball slide rails, so that drawing operation is realized.
When the flat plate type drawing structure is used, the supporting plate and the slideway have sliding friction, the friction force is large, and the drawing is laborious. Particularly, when the supporting plate is not flat, the friction resistance is larger, and the phenomenon that the supporting plate is pulled immovably sometimes occurs.
When the sliding rail type drawing structure is used, the support plate and the sliding rail are in rolling friction due to the balls in the sliding rail, so that the friction force is small, and the drawing is labor-saving. However, the enclosing plates of the flameproof shell are formed by bending through a bending machine, absolute parallelism of the enclosing plates on two sides cannot be guaranteed, and two wings, fixed by the sliding rails, on two sides of the supporting plate are also formed by bending, so that parallelism cannot be guaranteed, the tolerance is large sometimes, parallelism of the sliding rails on two sides cannot be guaranteed, the supporting plate can be pulled forcefully, and a heavy pulling structure cannot be used normally. Therefore, when the slide rail type drawing structure is installed, the slide rails need to be adjusted repeatedly to be parallel left and right and up and down, and the installation is time-consuming and labor-consuming.

The technical solutions of the present application will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.
Example 1
The embodiment provides a mining flame proof box is with floating self-interacting pull structure, as shown in fig. 1 and fig. 2, include:
the anti-explosion box comprises slide rails 1 arranged on two sides in the anti-explosion box, a supporting plate 6 arranged in the anti-explosion box and used for drawing, and right-angled fixing lugs 5, wherein the right-angled fixing lugs 5 are arranged on one side of the supporting plate 6, and the other side of the supporting plate 6 is fixedly arranged with the slide rails 1 on the corresponding side of the anti-explosion box;
one end of the right-angled-Z-shaped fixing lug 5 is arranged below the supporting plate 6 and is in floating connection with the supporting plate 6; the other end of the right-angled-square-shaped fixing lug 5 is fixedly mounted on the slide rail 1 on the side corresponding to the explosion-proof box.
In the embodiment, the slide rails 1 on two sides in the explosion-proof box are respectively fastened on the coamings on two sides of the explosion-proof box through screws, one side of the supporting plate 6 is fixedly connected with the slide rails 1 on the corresponding side of the explosion-proof box through screws, and the right-angled fixing lug 5 is installed on the other side of the supporting plate 6. One end of the Z-shaped fixing lug 5 is in floating connection with the supporting plate 6, and the other end of the Z-shaped fixing lug 5 is fixedly connected with the sliding rail 1 on the corresponding side in the explosion-proof box through a screw.
Optionally, this embodiment has set up nylon spacer 3, and the layer board 6 floats through nylon spacer 3 with "quarter-square" shape between the fixed ear 5 and is connected, specifically is:
waist type hole has been seted up along left right direction to layer board 6, nylon spacer 3 set up in the waist type hole, and the lower extreme of nylon spacer 3 closely laminates with "right-angled" shape fixed ear 5, the upper end of nylon spacer 3 is higher than layer board 6 upper surface setting distance. Meanwhile, an installation through hole is formed in the right-angled-Z-shaped fixing lug 5, the installation through hole is formed in the position, below the waist-shaped hole, corresponding to the waist-shaped hole, and the screw 2 penetrates through the nylon spacer 3 and the installation through hole and is fastened through the nut 4, so that the supporting plate 6 is connected with the right-angled-Z-shaped fixing lug 5.
In this embodiment, through setting up nylon spacer 3, layer board 6 has certain adjustment range in upper and lower direction, and nylon spacer 3 can freely slide in the waist type hole of layer board 6, and the slide rail angle of the inside both sides of explosion-proof box is adjustable to make layer board 6 can be at pull in-process automatically regulated height and angle, keep the depth of parallelism of the interior both sides slide rail of explosion-proof box all the time.
The sliding rail of this embodiment adopts the steel ball slide rail, is provided with the ball in the steel ball slide rail, and layer board and slide rail rolling friction, frictional force is less, and the pull is more laborsaving.
In this embodiment, a row of right-angled-z-shaped fixing lugs 5 are uniformly arranged on one side of the supporting plate 6 along the drawing direction of the supporting plate, as shown in fig. 3.
In the present embodiment, the "right-angled" shaped fixing lug 5 shown in fig. 1 and 2 is mounted on the right side of the supporting plate 6, and in other embodiments, the "right-angled" shaped fixing lug 5 may also be mounted on the left side of the supporting plate 6.
Taking the structure of fig. 1 and fig. 2 of this embodiment as an example, if the slide rails on both sides in the explosion-proof box are inclined from side to side after being installed, that is, the width of the inner opening of the enclosure plate of the explosion-proof box becomes larger or smaller along with the depth direction. If the width of the inner opening of the enclosing plate of the explosion-proof box is increased along with the depth direction, the supporting plate is extruded when being pulled outwards, the nylon isolating sleeve gradually moves leftwards in the waist-shaped hole, the left side and the right side of the supporting plate are automatically adjusted to be parallel, and the supporting plate is easily pulled out; when the supporting plate retreats inwards, the spacer sleeve is pulled to move rightwards gradually in the waist-shaped hole, the left side and the right side of the supporting plate can be automatically adjusted to be parallel, and the supporting plate can be easily retreated.
If the width of the inner opening of the enclosing plate of the explosion-proof box is reduced along with the depth direction, the supporting plate is pulled outwards and is subjected to the pulling effect, the spacer sleeve gradually moves rightwards in the waist-shaped hole, the left side and the right side of the supporting plate are automatically adjusted to be parallel, and the supporting plate is easily pulled out; when the supporting plate retreats inwards, the spacer sleeve gradually moves leftwards in the waist-shaped hole under the extrusion action, and the left side and the right side of the supporting plate can be automatically adjusted to be parallel, so that the supporting plate can be easily retreated.
If the explosion-proof incasement both sides slide rail installation back tilt up-and-down, the layer board is installed highly to take place the slope behind the slide rail promptly, if the layer board floats one side of installation and goes up/down the slope, because nylon spacer up end exceeds the layer board upper surface, the layer board receives certain squeezing action when the pull, can float downwards/upwards to keep the layer board both sides parallel, can easily pull the layer board.
Similarly, if the sliding rails on the two sides are inclined up, down, left and right, the automatic adjusting process is equivalent to the adjusting process of the two situations.
In the present embodiment, terms such as "upper", "lower", "left" and "right" are used for convenience of description only, and are not intended to limit the scope of the present invention, and changes or adjustments of the relative relationship thereof are considered to be within the scope of the present invention without substantial changes in the technical contents.
