Double-layer sealing box with large supporting device

Abstract

The invention relates to the technical field of sealing, and particularly discloses a double-layer sealing box with a large supporting device. The box comprises an outer box body, an inner box body and a large supporting device, wherein the inner box body is wrapped in the outer box body; the outer box body is connected with the inner box body through a large supporting device; the outer box bodycomprises an upper outer plate, an outer bottom plate, a horizontal side outer plate and a step side outer plate; the inner box body comprises an upper inner plate, a horizontal side inner plate, a step side inner plate and an inner bottom plate; the horizontal side outer plate and the step side outer plate are welded with the upper outer plate, the horizontal side inner plate and the step side inner plate are welded with the upper inner plate, the horizontal side outer plate and the step side outer plate are welded with the outer bottom plate, and the step side inner plate and the horizontalside inner plate are welded with the inner bottom plate. According to the double-layer sealing box, the bending position of the horizontal side inner plate bears large loads and does not deform, and therefore the requirement that a control device and an operation device are arranged in the double-layer sealing box under the condition that the sealing performance is not damaged is met.

Description

technical field

[0001] The invention relates to the field of sealing technology, in particular to a double-layer sealed box with a large supporting device. Background technique

[0002] As the use of airtight boxes becomes more and more extensive, the requirements for airtightness and functional diversity of airtight boxes are becoming more and more stringent. Especially in the application fields such as incubators, safes, and special boxes, in order to achieve better sealing performance, double-layer sealed structure boxes have been proposed.

[0003] The function of the double-layer sealed box in the prior art is simple, only has a single sealing performance, and complex devices cannot be arranged inside to control and operate the objects inside the box, so it does not have the function of controlling and operating the objects inside the box. For example, a double-layer sealed communication box disclosed by the Chinese patent with the notification number CN 208370059 U in...
