A glove box small transition cabin door and a glove box transition cabin

Abstract

The invention discloses a cabin door of a glove box small transition cabin. The cabin door is used for closing or opening a cabin body of the glove box small transition cabin, and comprises a cabin door, a sealing component and a cabin door opening and closing device, wherein the cabin door opening and closing device is arranged on the cabin body of the glove box small transition box; the cabin door per se is completely separated from the cabin body and is arranged on the cabin door opening and closing device; the cabin door opening and closing device drives the cabin door to move towards a cabin body opening from the opening state (no matter whether a cabin door support device rotates around an installing seat or the cabin door support device moves along the central axis of the cabin body), so the cabin door approximately horizontally or horizontally moves towards the cabin body; the periphery of the cabin door is approximately simultaneously or simultaneously pasted with the cabin body opening; meanwhile, the cabin door support device exerts free force on the center of the cabin door, and the free force is uniformly distributed onto the cabin door so that the cabin door can be freely pasted onto the cabin body opening of the cabin body; the stress of the sealing component in each direction is uniform; and the nonuniform deformation of the sealing component during the door closing can be avoided. Compared with the prior art, the cabin door has the advantages that the service life of the sealing component is prolonged; the structure is simple and reasonable; the operation is simple; and the sealing effect is good.

Description

technical field [0001] The invention belongs to the field of glove boxes, and in particular relates to a glove box small transition cabin door and a glove box transition cabin with simple structure, convenient operation and good sealing effect. Background technique [0002] The glove box is a laboratory equipment that fills the box with high-purity inert gas and circulates and filters out oxygen and moisture. The glove box includes a main box and a transition cabin, and the transition cabin is used as a transition space between the main box and the outside of the box. [0003] There are mainly two types of hatches in the existing transition cabin. One is the two-piece cover plate type. The two cover plates inside and outside can effectively isolate the main box from the outside world. However, the two-piece cover plate type has a complicated structure and costs It is high and inconvenient to operate; the second is the hinge on one side and the bolt on the other. Since one s...

Problems solved by technology

[0003] There are mainly two types of hatches in the existing transition cabin. One is the two-piece cover plate type. The two cover plates inside and outside can effectively isolate the main box from the outside world. However, the two-piece cover plate type has a complicated structure and costs High and inconvenient to operate; the second is the hinge on one side and the bolt on the other. Since one side of the hatch is fixed, the deformation of the sealing parts on both sides is inconsistent when the door is closed, making it difficult to close the door, and the sealing effect is not good, and the service life of the sealing parts is short
