Description

Technical Field

[0001] This utility model relates to the field of glove box technology, and in particular to a vacuum chamber assembly that is convenient for docking with a glove box. Background Technology

[0002] A glove box is a sealed working environment used for conducting experiments or operations in a controlled atmosphere to prevent interference from the external environment. Glove boxes typically contain gloves for handling objects inside while maintaining isolation from the outside environment. They are commonly used in fields such as chemistry, materials science, and electronics, especially in experiments involving high humidity, oxygen-sensitive substances, or hazardous chemicals. A vacuum chamber used for glove box docking refers to a cavity that connects to and works in conjunction with different devices (such as vacuum pumps, reactors, vacuum furnaces, etc.).

[0003] Chinese patent discloses a vacuum chamber structure that docks with a glove box (authorization announcement number CN210551362U). This patented technology facilitates docking between the vacuum chamber and the inert gas glove box by setting a sliding vacuum chamber door between them. This keeps the vacuum chamber under the protection of inert gas, effectively increasing the vacuuming time, preventing contamination, reducing the oxygen content in the chamber under high vacuum conditions, and making it easier to change samples, deposition materials, and deposition vessels. Moreover, it saves space compared to the round flange docking method.

[0004] However, most existing glove box vacuum chambers employ manual sealing methods, which increases the workload of operators. For example, the aforementioned comparative document uses a manual sealing method. In practical applications, manually sealing the glove box and vacuum chamber further increases the workload for operators and reduces its practicality. Therefore, those skilled in the art provide a vacuum chamber assembly that is convenient for docking with glove boxes to solve the problems mentioned in the background art. Utility Model Content

[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 technical solution for a vacuum chamber assembly for easy docking with a glove box: It includes a glove box body 1 and a vacuum chamber 2 disposed on one side of the glove box body 1. A first guide rail 31 and a second guide rail 32 are respectively arranged from top to bottom on the inner side of the glove box body 1 near the vacuum chamber 2. A sealing plate 3 is slidably installed between the first guide rail 31 and the second guide rail 32. A first sealing gasket 34 is disposed on one side of the sealing plate 3. A first electric telescopic rod 33 is symmetrically arranged inside the glove box body 1. A second electric telescopic rod 4 is symmetrically arranged on one side of the sealing plate 3. A sealing groove 42 is opened on the other side of the sealing plate 3. A sealing plate 41 is disposed inside the sealing groove 42. A second sealing gasket 43 is disposed on one side of the sealing plate 41. This arrangement utilizes the operation of the first electric telescopic rod 33 to... The sealing plate 3 moves inside the glove box body 1, thereby sealing the connection between the glove box body 1 and the vacuum chamber 2. Simultaneously, the operation of the second electric telescopic rod 4 moves the sealing plate 41 towards the glove box body 1, improving the sealing effect. No manual operation is required, reducing the workload of workers. It should be noted that the telescopic structure interfaces and electrical components of the first electric telescopic rod 33 and the second electric telescopic rod 4 effectively maintain a seal, preventing vacuum leakage. Both the first electric telescopic rod 33 and the second electric telescopic rod 4 are made of vacuum-resistant and corrosion-resistant materials. Furthermore, the power supply and control system of both the first electric telescopic rod 33 and the second electric telescopic rod 4 are connected to an external control system via a vacuum-sealed cable, ensuring the normal use of the glove box body 1 and demonstrating good practicality.

[0022] like Figure 2 As shown, the fixed end of the first electric telescopic rod 33 is installed on the inner surface of the glove box body 1, and the telescopic end of the first electric telescopic rod 33 is connected to the rear surface of the sealing plate 3. The lower surface of the first guide rail 31 and the upper surface of the second guide rail 32 are both provided with guide grooves. The sealing plate 3 is slidably installed inside the guide grooves. This arrangement uses the operation of the first electric telescopic rod 33 to guide the sealing plate 3 between the first guide rail 31 and the second guide rail 32, thereby adjusting the position of the sealing plate 3 to seal the glove box body 1 and the vacuum chamber 2.

[0023] like Figure 2 As shown, one side of the first sealing gasket 34 contacts the inner side of the glove box body 1, and the material of the first sealing gasket 34 is fluororubber. This arrangement utilizes the contact between the first sealing gasket 34 and the inner side of the glove box body 1 to achieve a seal on the connection of the glove box body 1.

[0024] like Figure 4As shown, the fixed end of the second electric telescopic rod 4 is installed on one side of the sealing plate 3, and the telescopic end of the second electric telescopic rod 4 is connected to one side of the sealing plate 41. One side of the second sealing gasket 43 contacts the inner side of the glove box body 1, and the material of the second sealing gasket 43 is silicone. This arrangement utilizes the operation of the second electric telescopic rod 4 to make the sealing plate 41 contact the inner side of the glove box body 1, thereby improving the sealing performance of the connection through the second sealing gasket 43.

[0025] The working principle of this utility model is as follows: When using the vacuum chamber assembly for easy docking with a glove box, firstly, by simultaneously activating the two first electric telescopic rods 33, the sealing plate 3 slides between the first guide rail 31 and the second guide rail 32, sealing the connection between the glove box body 1 and the vacuum chamber 2. The sealing performance at the connection is improved by the first sealing gasket 34. At the same time, by simultaneously activating the second electric telescopic rods 4 symmetrically arranged on one side of the sealing plate 3, the sealing plate 41 contacts the inside of the glove box body 1, thereby improving the sealing performance at the connection through the second sealing gasket 43. It has good practicality.

[0026] 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.
