Description

Technical Field

[0001] The utility model relates to the technical field of glove boxes, and more specifically to a high-sealing glove box. Background Art

[0002] A glove box generally refers to a vacuum glove box, also known as an inert gas protection box, dry box, etc. It is a laboratory equipment that fills high-purity inert gas into the box and circulates and filters out the active substances in it. It is widely used in ultra-pure environments without water, oxygen, and dust. It is an ideal device for scientific experiments in colleges and universities, scientific research institutions, and corporate laboratories. It is also widely used in biochemistry, metallurgy, electronics, chemical industry, geology, mining, medicine and other departments.

[0003] In the prior art, a Chinese patent publication number CN219275893U discloses a novel sealed glove box, in which a sealed door is installed on the front panel of the glove box body. When in use, the threaded rod can be driven to rotate by rotating the rotating rod, so that the sealed door is separated from the glove box cover and the external seal of the glove box body is opened, thereby ensuring the sealing effect of the glove box cover.

[0004] In the above-mentioned prior art, the failure of the sealing of the box when changing gloves can be avoided. However, when the gloves are changed, there is usually air inside the new gloves, or air enters when the package is opened. At this time, after the replacement is completed, the air inside the gloves will still enter the box and cause pollution inside the vacuum box. In general, it still has certain limitations in use.

DETAILED DESCRIPTION

[0024] The technical solution of the present invention will be clearly and completely described below in conjunction with the drawings in the present invention. In addition, the forms of the various structures recorded in the following embodiments are merely illustrative. The high-sealing glove box involved in the present invention is not limited to the various structures recorded in the following embodiments. All other embodiments obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the present invention.

[0025] Reference Figure 1-6 The utility model provides a high-sealing glove box, comprising: a glove box body 1, a glove mounting port 2, an operating glove 3, a sealing component, and an exhaust component. The glove mounting port 2 is opened on the front of the main body 1, and the operating glove 3 is detachably mounted on the glove mounting port 2. The sealing component is installed in the main body 1, and the glove mounting port 2 is sealed by the sealing component. The exhaust component is connected to the glove mounting port 2, and the gas in the glove mounting port 2 can be extracted through the exhaust component.

[0026] The sealing assembly includes a sealing plate 4, which is slidably mounted on the inner wall of the main body 1, and the sealing plate 4 can cover and seal the glove installation port 2. The sealing plate 4 is equipped with a control component, which controls the movement of the sealing plate 4 to block the glove installation port 2.

[0027] The control component includes a screw rod 5, which is rotatably installed in the main body 1. A threaded seat 6 is threadedly installed on the surface of the screw rod 5, and the threaded seat 6 is fixed to the side of the sealing plate 4. In this way, by rotating the screw rod 5, the threaded seat 6 can be driven to move, thereby driving the sealing plate 4 to move.

[0028] There are two groups of screw rods 5, which are symmetrically distributed on the left and right sides of the sealing plate 4. At the same time, the two screw rods 5 are driven by pulleys 7 and synchronous belts 8. The screw rods 5 are equipped with a power component, which drives the screw rods 5 to rotate. In this way, it can be ensured that the screw rods 5 can smoothly drive the threaded seat 6 to move.

[0029] The power assembly includes a gear box 9, which is fixedly installed in the main body 1. A driving bevel gear 10 and a driven bevel gear 11 are rotatably installed inside the gear box 9, and the driving bevel gear 10 is meshed with the driven bevel gear 11. At the same time, the end of the rotating shaft of the driven bevel gear 11 passes through the gear box 9 and is coaxially connected to the bottom end of the screw rod 5. A hand wheel 12 is rotatably installed on the front of the main body 1, and the rotating shaft of the hand wheel 12 is coaxially connected to the rotating shaft of the driving bevel gear 10. In this way, by turning the hand wheel 12, the hand wheel 12 will drive the driving bevel gear 10 to rotate, and then drive the driven bevel gear 11 to rotate, so as to drive the screw rod 5 to rotate.

[0030] The exhaust assembly includes an air pump 13, the air inlet of the air pump 13 is connected to an exhaust pipe 14, and the end of the exhaust pipe 14 away from the air pump 13 is connected to the glove mounting port 2, the air outlet of the air pump 13 is installed with an exhaust pipe 15, and the exhaust pipe 15 extends to the outside of the main body 1 away from the end of the air pump 13, and a transmission assembly is connected between the air pump 13 and the gear box 9. In this way, when the air pump 13 rotates, the air pump 13 will exhaust air from the glove mounting port 2 through the exhaust pipe 14. At this time, if a new operating glove 3 is installed, the inside of the newly installed operating glove 3 can be exhausted.

[0031] The transmission assembly includes a transmission bevel gear 16, which is rotatably installed inside the gear box 9, and the transmission bevel gear 16 is meshed with the driven bevel gear 11. At the same time, the transmission bevel gear 16 is coaxially connected to the rotating shaft of the air pump 13. In this way, the driven bevel gear 11 can drive the transmission bevel gear 16 to rotate, and then drive the air pump 13 to rotate.

[0032] The transmission assembly also includes an electric clutch 17 , which is mounted on the surface of the gear box 9 and connected between the rotating shaft of the driven bevel gear 11 and the rotating shaft of the screw 5 , thereby controlling the transmission engagement between the driven bevel gear 11 and the screw 5 .

[0033] Therefore, the complete usage process is that when the gloves need to be replaced, only the hand wheel 12 needs to be turned, and the hand wheel 12 will drive the active bevel gear 10 to rotate, and then drive the driven bevel gear 11 to rotate, to drive the screw rod 5 to rotate, and the screw rod 5 will drive the threaded seat 6 to move, and then drive the sealing plate 4 to move, until the sealing plate 4 seals the glove installation port 2. At this time, the operating glove 3 that needs to be replaced can be removed and a new operating glove 3 can be installed. Then the electric clutch 17 is controlled to disconnect the connection between the driven bevel gear 11 and the screw rod 5, and then the hand wheel 12 is turned again. At this time, the driven bevel gear 11 can only drive the transmission bevel gear 16 to rotate, and then drive the air pump 13 to rotate alone. The air pump 13 will exhaust the glove installation port 2 through the exhaust pipe 14, and then exhaust the inside of the newly installed operating glove 3 until the air in the new operating glove 3 is completely discharged. At this time, the electric clutch 17 is controlled to connect the connection between the driven bevel gear 11 and the screw rod 5, and then the hand wheel 12 is turned in the opposite direction to lower the sealing plate 4. In this way, the entire replacement process is completed.

[0034] To sum up, during the entire process of replacing the operating gloves 3, the operating gloves 3 are first isolated from the glove box, and then the operating gloves 3 are replaced separately. Moreover, after the replacement is completed, the operating gloves 3 are evacuated separately to discharge the internal air. In this way, the cleanliness of the gas inside the glove box can be ensured, thereby effectively ensuring the sealing.

[0035] At the same time, during use, when work is not needed, the sealing plate 4 can be raised to isolate the air inside the operating glove 3. In this way, the operating glove 3 can be hung down, thereby reducing the space occupied by the entire operating glove 3 to facilitate the passage of workshop or laboratory staff. Overall, the function is more complete.

[0036] Finally, it should be noted that: the drawings of the embodiments disclosed in the present utility model only involve structures related to the embodiments disclosed in the present utility model, and other structures can refer to the general design. In the absence of conflict, the same embodiment and different embodiments of the present utility model can be combined with each other;
