High temperature resistance large double-layer sealing box with internal supporting structure

Abstract

The invention provides a high temperature resistance large double-layer sealing box with an internal supporting structure, The high temperature resistance large double-layer sealing box comprises an outer layer box body, an inner layer box body, the internal supporting structure, connecting devices I and a connecting device II, wherein the outer layer box body wraps around the inner layer box body, the outer layer box body and the inner layer box body are connected through the internal supporting structure and the connecting device II, the outer layer box body is formed by splicing a bottom plate and a plurality of outer plates to form a box body structure, all the parts are connected in a sliding mode through the connecting devices I, the inner layer box body is formed by splicing a bottom plate and a plurality of inner plates to form a box body structure, and the connecting mode of all the parts is the same as that of the outer layer box body. According to the high temperature resistance large double-layer sealing box, through arrangement of the internal supporting structure, loads generated by an internal operation device can be borne and dispersed; and in addition, during high-temperature thermal expansion, relative sliding can be generated at the joints of the outer layer box body and the inner layer box body and between internal supporting steel and a sliding sealing gasket, and structural damage at the joints during the thermal expansion is effectively avoided.

Description

Technical field [0001] The invention relates to the technical field of sealing, in particular to a large double-layer sealed box with an internal support structure and high temperature resistance. Background technique [0002] As the use of the sealed box becomes more and more extensive, the requirements for the tightness and functional diversity of the sealed box are becoming more and more stringent. Especially in the application fields of incubators, safes, special boxes, etc., in order to achieve better sealing performance, double-sealed structural boxes are proposed. [0003] The double-layer sealed box in the prior art has simple functions and only has a single sealing performance. It is impossible to arrange complicated devices inside to control and operate the objects inside the box, especially when it is difficult to ensure the stability of operation under heavy load conditions. And structural safety; when the box needs to withstand high temperatures, the double-layer seal...

AI Technical Summary

Problems solved by technology

[0004] In view of the above-mentioned problems that it is difficult to arrange complex control and operating devices in the double-layer sealed box, it is difficult to ensure the stability of operation and structural safety, and the problems of expansion and deformation under high temperature, the present invention provides a large-scale double-layer sealed box with internal support structure and high temperature resistance. Large double-layer sealed box that can be easily disassembled, can withstand heavy loads and withstand high temperatures
