Problems solved by technology
[0003] The self-adaptive hinge of the present invention, after being assembled on the closed shell with a door cover to connect the shell door cover and the shell main body, can solve the problem that the fit gap between the original hinge structures affects the self-closing and sealing performance of the shell, and can solve the problem of The problem that the joint surface of the door cover and the shell body is not suitable for assembly of sealing materials also solves the problem that the joint surface is damaged and it is difficult to repair the quality without changing the assembly of the hinge

Embodiment approach 1
[0015] An example of implementation mode, welded type, the outline structure diagram is as attached Figure 5 shown. Both the hinge seat and the hinge arm are respectively fixed on the shell main body and the shell door close to the joint surface of the cover by welding.
Embodiment approach 2
[0016] An example of the second embodiment, the bolt-fixed type, the outline structure diagram is attached Image 6 shown. The corresponding hinge seat structure outline drawing is attached Figure 7 shown, bolted to the housing body via the mounting plate. Corresponding structure diagram of hinge arm is attached Figure 8 As shown, bolt directly to the shell door cover.
[0017] The examples of specific implementations listed above are only a part of many applications, and the adaptive hinge of the present invention can also have other welding assembly and bolt assembly methods or their different combinations in application.
[0018] In specific implementation, the hinge seat can be appropriately deformed, and the hinge arm and the special-shaped shaft can be made into one body.

The invention provides a self-adaptive hinge, relates to a door cover assembly hinge of a sealing shell with a cover and particularly an explosion-proof cabinet shell, and is used for solving the problems that the conventional hinge assembling requirement is high, the corresponding shell cover closing joint surface is not suitable for being provided with a sealing material, and the shell cover closing joint surface is not prone to repair after being damaged. The hinge mainly comprises the component parts such as a combined piece of a hinge arm 3 and a special-shaped shaft 4 and a hinge seat 2.After the hinge is assembled on the shell, the shell door cover can be rotated relative to a shell main body around the special-shaped shaft 4 and can move properly in a translational mode relative to the shell main body in the restricted range, the hinge can automatically adapt to the situations that the shell cover closing joint surface is provided with and without the sealing material and thepre-fastening and post-fastening states of the shell door cover closing, the operation is convenient and flexible, the application range is wide, and the hinge is is particularly suitable for the explosion-proof cabinet shell door cover assembly produced according to national explosion-proof electrical standards.
Description
technical field [0001] The invention relates to a shell with a door cover which requires sealing, in particular to an explosion-proof cabinet shell with a door cover for an explosive environment. Specifically relate to a kind of hinge that the shell door cover of these shells is connected with shell main body. Background technique [0002] Existing hinges in this field can usually be summarized as being composed of connecting round shafts and shaft sleeves assembled on the shaft. Different shaft sleeves are respectively fixed on the shell door cover and the shell main body, so that the shell door cover can be opposite to each other in the working plane. The shell main body rotates around the connecting circular axis. The size of the fit gap between the hinge itself will affect the closing performance of the shell; the joint surface of the shell door cover and the main body of the shell is not suitable for assembly of sealing materials; if the joint surface is damaged, it is...
