Description

Technical Field

[0001] The utility model relates to the technical field of glove boxes, in particular to a sealing structure between a glove box and a transition bin. Background Art

[0002] A glove box is a laboratory equipment that fills high-purity inert gas into the box body and circulates and filters out the active substances therein. It is also called a vacuum glove box. The transition bin is an important part of the glove box. It is located between the glove box body and the external environment and serves as a filtering space between the two. Therefore, it is required that there is efficient sealing between the transition bin and the glove box to prevent external air from entering the glove box and affecting the experiment.

[0003] The Chinese patent discloses a sealing structure between a glove box and a transition bin (publication number CN220373312U). In this patented technology, the rotating rod is driven to rotate by a motor, and the rotating rod squeezes the connecting plate, so that the contact head is completely attached to the contact seat. The electric cylinder drives the sealing door to move upward, and an object is placed. Then the head is separated from the contact seat, air is extracted, high-purity inert gas is filled, and the placing disc rotates the object into the glove box body, thus avoiding the entry of external air into the glove box body and the oxidation of the product.

[0004] However, most of the existing sealing methods for the transition bin use an inner door and an outer door to achieve the sealing purpose, resulting in the need for alternating replacement during sealing, which is inconvenient to operate and affects the use. For example, in the above-mentioned comparative document, it adopts the inner door and outer door method. In actual application, when the filter bin uses the inner door and outer door for sealing, two methods are required to achieve its alternating sealing, resulting in a slow sealing efficiency. Therefore, those skilled in the art provide a sealing structure between a glove box and a transition bin to solve the problems raised in the above background art. Summary of the Utility Model

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0021] Please refer to Figures 1-4 , the present invention provides a technical solution for a sealing structure of a glove box and a transition bin: including: a glove box 1 and a transition bin 2 provided on one side of the glove box 1. The upper surface of the transition bin 2 is provided with a mounting plate 31, and a sealing motor 3 is fixed on the upper surface of the mounting plate 31. The driving end of the sealing motor 3 is connected to a rotating shaft 32 inside the transition bin 2. A limiting rod 321 is disposed through the outside of the rotating shaft 32, and a connecting cylinder 41 is connected to the outside of the rotating shaft 32 inside the transition bin 2. Sealing plates 4 are symmetrically arranged on the outside of the connecting cylinder 41. A second sealing gasket 42 is arranged on the outside of the sealing plate 4. First sealing gaskets 21 are arranged on both the upper surface and the lower surface inside the transition bin 2. This setting makes the rotating shaft 32 rotate by the operation of the sealing motor 3, and then the sealing plate 4 outside the connecting cylinder 41 can rotate to achieve the purpose of connecting the glove box 1 to the outside through the transition bin 2. The structure is simple, and there are four such sealing plates 4, so that the transition bin 2 can always be in a sealed state.

[0022] As Figure 1 shown, the materials of both the first sealing gasket 21 and the second sealing gasket 42 are rubber materials. The outside of the second sealing gasket 42 is in contact with the inside of the transition bin 2, and the upper surface and the lower surface of the sealing plate 4 are in contact with the outer surface of the first sealing gasket 21. This setting can improve the sealing performance of the transition bin 2 by using the first sealing gasket 21 and the second sealing gasket 42, so as to facilitate the normal use of the glove box 1.

[0023] As Figure 2As shown in the figure, positioning bolts are symmetrically installed on the upper surface of the mounting disc 31. Mounting holes 23 are provided on the upper surface of the transition bin 2. The lower end of the positioning bolt penetrates through the lower surface of the mounting disc 31 and is embedded inside the mounting hole 23 and threadedly connected to the mounting hole 23. This setting utilizes the threaded connection between the positioning bolt and the mounting hole 23, so as to achieve the purpose of installing and using the sealing motor 3 on the mounting disc 31.

[0024] As Figure 2 shown in the figure, fixing holes 22 are provided on the upper surface of the transition bin 2. The lower end of the rotating shaft 32 penetrates through the inside of the fixing hole 22. This setting facilitates the rotation shaft 32 to penetrate through its inside by means of the provision of the fixing hole 22, so as to be installed on the outside of the connecting cylinder 41.

[0025] As Figure 4 shown in the figure, limiting holes 411 are symmetrically provided on the inner side of the connecting cylinder 41. One end of the limiting rod 321 is embedded inside the limiting hole 411. A fixing groove 322 is provided inside the rotating shaft 32. An electric telescopic rod 323 is arranged inside the fixing groove 322. One end of the limiting rod 321 is connected to a connecting plate 324. The telescopic end of the electric telescopic rod 323 is connected to one end of the connecting plate 324. This setting utilizes the operation of the electric telescopic rod 323. In this way, after the rotating shaft 32 is installed inside the connecting cylinder 41, one end of the limiting rod 321 will be embedded inside the limiting hole 411, and thus the purpose of installing the connecting cylinder 41 can be achieved, so as to facilitate the subsequent purpose of rotary sealing.

[0026] The working principle of the present utility model is as follows: When the sealing structure of the glove box and the transition bin of the present utility model is in use, first, the connecting cylinder 41 is installed inside the transition bin 2. After installation, the mounting disc 31 is installed on the upper surface of the transition bin 2 and threadedly connected to the mounting hole 23 through bolts. In this way, the mounting disc 31 can be installed, that is, the installation of the sealing motor 3 is achieved. When installing, the rotating shaft 32 will enter the inside of the connecting cylinder 41. After entering, the electric telescopic rod 323 can make the limiting rod 321 penetrate through the inside of the fixing groove 322 and be embedded inside the limiting hole 411, and thus the installation of the connecting cylinder 41 and the rotating shaft 32 can be achieved. After installation, the operation of the sealing motor 3 will make the rotating shaft 32 rotate, and thus the sealing plate 4 outside the connecting cylinder 41 can rotate to achieve the purpose of connecting the glove box 1 with the external environment. At the same time, the sealing plate 4 is provided with four, which can achieve the purpose of efficient sealing during rotation, and has good practicability.

[0027] The above is only the preferred embodiment of the present utility model. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present utility model, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model. The structures, devices and operation methods not specifically described and explained in the present utility model, without special instructions and limitations, are implemented according to the conventional means in this field.
