[0023] The outer ring body 10 has an extension section 11 at one end, which is used to extend into the glove box. The inner ring body 20 is screwed to the extension section 11. During installation, the extension section 11 is inserted into the glove box, and then the inner ring body 20 is screwed to the extension section 11, so that the outer ring body 10 is distributed on the outside of the glove box and the inner ring body 20 is distributed on the inside of the glove box.

[0024] A second elastic ring 21 is provided on the side of the inner ring 20 and the outer ring 10 that are close to each other. The second elastic ring 21 is used to abut against the glove box wall to improve the sealing performance.

[0025] The outer ring body 10 has a fixed cylinder 12 at the other end. The frame plate 30 is connected to the outer ring body 10 through the pad 101. The frame plate 30 is made of transparent plastic. The frame plate 30 is slidably fitted with a movable plate 40. The movable plate 40 has a sleeve 43. A movable cylinder 44 is inserted through the sleeve 43. A plurality of first elastic rings 443 are provided on the outer wall of the movable cylinder 44. The plurality of first elastic rings 443 abut against the inner wall of the sleeve 43. The movable cylinder 44 has a step 441 for installing rubber gloves 45. An elastic sealing layer 401 is provided on the inner side of the movable plate 40. The elastic sealing layer 401 abuts against the front end of the fixed cylinder 12. The movable plate 40 can move vertically along the frame plate 30 to drive the sleeve 43 to dock or stagger with the fixed cylinder 12.

[0026] The elastic sealing layer 401, the first elastic ring 44, and the second elastic ring 21 are all made of wear-resistant rubber material;

[0027] When the sleeve 43 is connected to the fixed cylinder 12, the movable cylinder 44 is pushed into the sleeve 43, allowing the rubber glove 45 to be inserted into the glove box for experimental operations. When the sleeve 43 and the fixed cylinder 12 are misaligned, the elastic sealing layer 401 contacts the fixed cylinder 12 to form a seal. The movable cylinder 44 is pulled out along the sleeve 43, exposing the step 441 outside the sleeve 43, allowing the rubber glove 45 to be disassembled and replaced. During the glove replacement process, the inside of the glove box is effectively prevented from being directly exposed to the air for a long time, effectively reducing the entry of external dust and other impurities, making the experimental environment inside the glove box less susceptible to dust interference.

[0028] The sleeve 43 is located on the upper part of the movable plate 40. During the experiment, the lower part of the movable plate 40 is located below the fixed cylinder 12, so it will not obstruct the view of the glove box.
