Problems solved by technology

[0007] The technical problem to be solved by the present invention is: in order to solve the problem in the prior art, because the inner hinge structure is relatively thin, the requirements for the welding position of the hinge are relatively high, and the deviation of the welding position is very easy to occur, which will cause the hinge to be pulled and deformed, and the box body will not be tightly sealed. The problem

Embodiment 1

[0030] This embodiment provides an inner hinge mechanism of a mine intrinsically safe box, such as Figure 3 to Figure 4 shown, including:

[0031] The upper base 11, the lower base 10, the upper connecting piece 6 and the lower connecting piece 7, the upper base 11 is assembled on the box cover 5, and the lower base 10 is assembled on the box body 1;

[0032] The upper connecting piece 6 includes a box cover hinge portion and a first connecting piece hinge portion, the lower connecting piece 7 includes a box body hinge portion and a second connecting piece hinge portion, and the box cover hinge portion and the upper base 11 pass through the first connecting piece. A pin shaft 12 realizes living hinge, the hinge part of the first connecting member and the hinge part of the second connecting member realize living hinge through the second pin shaft 8, and the hinge part of the box body and the lower base 10 are connected by a third pin shaft 9 Realize the living hinge.

Embodiment 2

[0057] This embodiment provides an intrinsically safe mine box, including the inner hinge mechanism described in Embodiment 1. Figure 5 Shown is the schematic diagram of the intrinsically safe box installed with the hinge mechanism described in Embodiment 1 of the present invention.

[0058] Since the intrinsically safe box of this embodiment adopts the installation form of the inner hinge, the overall appearance of the intrinsically safe box will not be affected. Moreover, due to the inner hinge mechanism in Example 1, the sealing performance of the intrinsically safe box is better.

[0059] As a possible example, as Figure 5 As shown, two first fixing holes 14 are arranged on the side of the box cover 5 close to the hinge mechanism, and two second fixing holes 15 are arranged on the side of the box cover 5 opposite to the hinge mechanism for passing Four-point fixing realizes the sealing and fixing of the box cover 5 and the box body 1 .

[0060] In this embodiment, two...

Abstract

The application relates to a mine intrinsically safe box and its inner hinge mechanism, an upper base, a lower base, an upper connecting piece and a lower connecting piece, the upper base is assembled on the box cover, and the lower base is assembled on the box body, The upper connecting piece includes a box cover hinge portion and a first connecting piece hinge portion, the lower connecting piece includes a box body hinge portion and a second connecting piece hinge portion, and the box cover hinge portion and the upper base pass through a first pin shaft To realize living hinge, the hinge part of the first connecting piece and the hinge part of the second connecting piece realize living hinge through the second pin shaft, and the box body hinge part and the lower base realize living hinge through the third pin shaft.

Description

technical field [0001] The application belongs to the technical field of mine intrinsically safe electrical equipment, and in particular relates to a mine intrinsically safe box and its inner hinge mechanism. Background technique [0002] The mine intrinsically safe box includes a box structure, and the box structure is provided with a box cover. During installation, the box cover and the box body are hinged to realize the opening and installation of the box cover. The box structure in the prior art is similar to that of the box. The lid is linked by hinges. [0003] At present, there are mainly two types of hinges that are often used, one of which is an internal hinge, such as figure 1 As shown, the first hinge structure 4 and the second hinge structure 3 of the inner hinge can be respectively mounted on the box cover 5 and the box body 1 by welding or screwing. The first hinge structure 4 and the second hinge The hinge structure 3 is hinged through the hinge pin 2 . The...
