Description

Technical Field

[0001] This utility model relates to the technical field of vacuum glove box equipment, specifically to a transition compartment of a vacuum glove box. Background Technology

[0002] Vacuum glove boxes are highly specialized devices that provide reliable protection for experiments and production operations that are extremely sensitive to environmental conditions by creating a highly clean, specific atmosphere with low water and oxygen content in a sealed environment. They play a key role in many fields. As a key connecting component between the vacuum glove box and the external environment, the performance of the transition chamber directly affects the operation of the entire system.

[0003] Existing circular transition chambers have inlet and outlet ports on their two circular side walls. This design makes the size of the inlet and outlet ports smaller than the circular side walls of the transition chamber, which usually cannot meet the requirements for transferring materials that are too large. Therefore, square vacuum chambers are currently used to transfer large materials. However, when vacuuming the vacuum chamber, the square vacuum chamber has insufficient pressure resistance and is prone to deformation or damage. It is necessary to use high-strength materials to manufacture square vacuum chambers, which greatly increases the cost of the equipment. To address this, we propose a transition chamber based on a vacuum glove box. Utility Model Content

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0027] See attached document Figure 1-5 A transition chamber for a vacuum glove box includes a transition chamber body 1. To ensure structural strength during vacuuming, the transition chamber body 1 is a hollow cylinder capable of withstanding strong pressure and preventing deformation and damage during vacuuming. Two material inlets 11 are opened on its sides, one inside the glove box and the other connecting to the outside. Both material inlets 11 are equipped with sealing doors 2 to ensure vacuuming of the interior of the transition chamber body 1. The cylindrical shape of the transition chamber body 1, with openings on both sides, ensures the conveying of large materials while maintaining structural strength.

[0028] To ensure that the bottom of the transition chamber body 1 has a larger load-bearing space, the angle between the two material inlets 11 and the axis of the transition chamber body 1 is less than 90°, and the angle between the other side of the two material inlets 11 and the axis of the transition chamber body 1 is greater than 120°. This allows for the installation of a wider load-bearing plate at the bottom of the transition chamber body 1 to support larger materials.

[0029] During operation, the transition chamber body 1 needs to withstand certain pressure changes. To enhance its structural strength and prevent deformation due to pressure fluctuations, several circular ribs 13 and first arc-shaped ribs 14 are installed in the cylindrical inner cavity of the transition chamber body 1. The outer walls of the circular ribs 13 are fitted into the cylindrical inner cavity of the transition chamber body 1 and distributed at both ends of the transition chamber body 1, effectively dispersing and bearing the internal pressure on both sides of the transition chamber body 1 during vacuuming, thus enhancing the overall pressure resistance of the transition chamber body 1. The first arc-shaped ribs 14 are fitted into... The inner cavity between the two material inlets 11 inside the transition chamber body 1 has a sealing door 2 consisting of an outer plate 21 and an inner plate 22. The inner plate 22 has several second arc-shaped ribs 23 on one side facing the inner cavity of the transition chamber body 1. The two ends of the second arc-shaped ribs 23 respectively abut against the first arc-shaped ribs 14 on both sides. The inner plate 22 supports the inner wall of the material inlets 11. The second arc-shaped ribs 23, together with the first arc-shaped ribs 14, support the inner side of the material inlets 11 of the transition chamber body 1, further improving the pressure-bearing capacity at this location and ensuring the structural strength of the transition chamber body 1.

[0030] The outer plate 21 is larger than the inner plate 22, and one side of it abuts against the outer wall of the transition chamber body 1. The inner plate 22 is inserted into the material port 11, and the two are matched in size, which ensures the sealing performance between the sealing door 2 and the material port 11, effectively preventing the entry of outside air and impurities.

[0031] In this embodiment, in order to ensure the stability of the sealing door 2 in the closed state, the outer wall of the transition chamber body 1 is provided with a number of bearing blocks 12 distributed on both sides of the material inlet 11. Each bearing block 12 is provided with an upward-opening bearing groove. The bearing grooves of the paired bearing blocks 12 are jointly placed with a limiting rod 3. The side wall of the limiting rod 3 abuts against the outer wall of the sealing door 2. When the sealing door 2 is closed, the limiting rod 3 is placed in the bearing groove. The limiting rod 3 will tightly abut against the sealing door 2, effectively restricting the opening action of the sealing door 2, providing a guarantee for the sealing performance of the transition chamber, and greatly improving the safety and reliability of the equipment.

[0032] The sealing door 2 is provided with a handle 24 on the side opposite to the transition chamber body 1. When opening the sealing door 2, simply lift the limit rod 3 upwards to remove the limit rod 3 in the bearing groove. Then, the sealing door 2 can be pulled out of the material outlet 11 through the handle 24. At this time, the material can be put into or taken out of the transition chamber body 1. The sealing door 2 is simple and quick to open.

[0033] In order to prevent the limiting rod 3 from moving in the bearing groove and affecting its limiting of the sealing door 2, two limiting rings 31 are provided on the limiting rod 3. The two limiting rings 31 respectively abut against the opposite or opposite sides of the paired bearing blocks 12, ensuring that the limiting rod 3 will not shake at will.

[0034] In this embodiment, to facilitate the connection between the transition chamber body 1 and the glove box, a mounting plate 15 for connecting with the glove box is provided on the transition chamber body 1. A reinforcing plate 16 that can be inserted into the glove box is provided on the side of the mounting plate 15 facing the glove box. Mounting holes are provided on both the mounting plate 15 and the reinforcing plate 16. The transition chamber body 1 and the glove box can be connected together by nuts simply by pre-installing bolts that match the mounting holes on the mounting plate 15 on the glove box. The mounting holes on the reinforcing plate 16 help to further improve the connection stability between the transition chamber body 1 and the glove box.

[0035] In this embodiment, in order to ensure the structural strength of the transition chamber body 1, an air pipe 4 for air inlet and outlet is installed on the circular bottom wall of the transition chamber body 1, which effectively prevents the holes in the air pipe 4 from damaging the integrity of the outer wall of the transition chamber body 1.
