Technical Field
[0001] This utility model relates to the field of vacuum glove box technology, and in particular to a leak-proof glove structure specifically for vacuum glove boxes. Background Technology
[0002] A vacuum glove box is a sealed box that can be evacuated or filled with a specific gas to isolate the experiment or operation from the influence of external air, moisture, oxygen, etc. It is widely used in chemical experiments, semiconductor manufacturing, materials science research, drug development and other fields. The glove structure is one of the core components of the vacuum glove box. It allows operators to conduct experiments in a sealed environment without being exposed to the outside environment, ensuring the stability and safety of the experimental process.
[0003] Chinese patent discloses a leak-proof glove specifically for vacuum glove boxes (publication number CN216634474U). This patented technology includes a fixing ring with a fixing structure. The fixing structure includes a pressure ring, which is slidably connected to the fixing ring. The pressure ring abuts against multiple first locking blocks, which are slidably connected to the fixing ring. The first locking blocks engage with second locking blocks, and the multiple second locking blocks are slidably connected to the vacuum glove box. This technology achieves rapid connection between the fixing ring and the vacuum glove box, shortens the connection time, and improves the efficiency of the fixing ring connection.
[0004] However, most existing leak-proof methods for vacuum glove boxes involve setting multiple structures outside the positioning ring to cooperate with the vacuum glove box for sealing, as in the aforementioned comparative document. In practical applications, using multiple structures is inconvenient during operation, affecting leak-proof performance. Furthermore, it only achieves a seal between the glove and the glove box, failing to seal the end face to improve leak-proof effectiveness, resulting in low practicality. Therefore, those skilled in the art provide a leak-proof glove structure specifically for vacuum glove boxes to solve the problems mentioned in the background art. Utility Model Content
[0005] To address the shortcomings of existing technologies, this utility model provides a leak-proof glove structure specifically for vacuum glove boxes, solving the problems mentioned in the background section.

[0012] This utility model provides a leak-proof glove structure specifically for vacuum glove boxes, which has the following advantages compared with the prior art:
[0013] 1. This design provides a leak-proof glove structure specifically for vacuum glove boxes. Through the arrangement of a sealing plate, a screw, a second sealing gasket, and a bearing, the sealing plate moves in a fixed groove outside the positioning ring when the screw rotates, and is embedded inside the sealing groove.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0021] Please see Figure 1-4This utility model provides a structural solution for a leak-proof glove for a vacuum glove box: It includes a vacuum glove box body 1, a positioning ring 2 installed inside the vacuum glove box body 1, one end of the positioning ring 2 connected to a glove body 21, and a sealing disc 3 connected to another end of the positioning ring 2. A connecting sleeve 32 is connected to one end of the sealing disc 3 inside the positioning ring 2, and a first sealing gasket 31 is provided on one side of the sealing disc 3 near the vacuum glove box body 1. A sealing groove 11 is formed on the inner side of the vacuum glove box body 1, and a fixing groove is formed on the outer side of the positioning ring 2. A sealing plate 4 is symmetrically arranged inside the fixed groove, and a second sealing gasket 42 is arranged outside the sealing plate 4. A rotating groove is opened on the inner side of the positioning ring 2, and a screw 41 is arranged inside the rotating groove. This arrangement allows the sealing plate 4 to move outward inside the fixed groove by rotating the screw 41, so that the second sealing gasket 42 enters the sealing groove 11. This achieves the sealing between the glove body 21 and the vacuum glove box body 1. At the same time, the first sealing gasket 31 on one side of the sealing plate 3 can improve the sealing of the glove body 21 connection and prevent leakage.
[0022] like Figure 3 and Figure 4 As shown, the second sealing gasket 42 is adapted to the sealing groove 11, and the material of the second sealing gasket 42 is rubber. The inner side of the sealing plate 4 is equipped with a bearing 43 inside the rotating groove. One end of the screw 41 is embedded in the bearing 43 and rotatably connected to the bearing 43. The screw 41 is provided with an external thread, and the screw 41 is threadedly connected to the sealing plate 4. This arrangement allows the sealing plate 4 to move outward inside the fixed groove when the screw 41 rotates, and stops after the second sealing gasket 42 enters the sealing groove 11. At this time, the sealing plate 4 is still inside the fixed groove. This can be used to improve the sealing performance of the connection between the glove body 21 and the vacuum glove box body 1 and prevent leakage.
[0023] like Figure 2 As shown, the connecting sleeve 32 has external threads on its outside, and the vacuum glove box body 1 has internal threads that engage with each other on its inside. One side of the first sealing gasket 31 contacts the outside of the vacuum glove box body 1, and the material of the first sealing gasket 31 is also rubber. This arrangement utilizes the connecting sleeve 32 to connect with the vacuum glove box body 1 by threads, thus achieving the purpose of quick installation of the sealing disc 3, and the first sealing gasket 31 can improve the leak-proof effect of the glove body 21.
[0024] The working principle of this utility model is as follows: When using the special leak-proof glove structure for vacuum glove boxes, the sealing disc 3 is installed onto one end of the positioning ring 2. During installation, the connecting sleeve 32 can be embedded into the positioning ring 2 and threadedly connected to it, thus achieving the connection of the sealing disc 3. After installation, the positioning ring 2 can be installed inside the vacuum glove box body 1 and limited by the sealing disc 3. The sealing disc 3 is fixed to the outside of the vacuum glove box body 1 by bolts, and the sealing at the connection point is improved by the first sealing gasket 31. Simultaneously, when a hand is inserted... Rotate the screw 41 into the positioning ring 2. During rotation, since the screw 41 is threadedly connected to the positioning ring 2, the screw 41 will cause the sealing plate 4 to move outward inside the fixed groove. It will stop after the second sealing gasket 42 enters the sealing groove 11. At this time, the sealing plate 4 is still inside the fixed groove. This can be used to improve the sealing performance of the connection between the glove body 21 and the vacuum glove box body 1, and prevent leakage. This setting has a simple structure, is easy to operate, and can achieve double sealing of the glove body 21 with good leakage prevention effect.
[0025] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model are implemented according to conventional methods in the art, unless otherwise specified or limited.
