Example

[0025] like Figure 2 As shown, the balancing mechanism includes a compression spring 7 arranged in any group of slots 5, a fixing plate 8 is arranged at the top and bottom of the compression spring 7, a buffer block 9 is arranged at the ends of the two groups of fixing plates 8 located in any group of slots 5 away from each other, and the end surfaces of the upper glass 1 and the lower glass 2 close to each other are in contact with several groups of buffer blocks 9, a square through hole 10 is arranged on one side of the shell 3, the square through hole 10 is connected to the cavity 4, four groups of slide grooves 11 are arranged on the inner wall of the square through hole 10, and any group of slide grooves 11 is provided A fixing block 12, two groups of fixing blocks 12 are provided with a spring rod 13 at one end away from the cavity 4, a sealing plate 14 is provided on the two groups of spring rods 13 at one end away from the cavity 4, an interface 15 is provided at the center of the sealing plate 14, any group of fixing blocks 12 is arranged at the center of the corresponding slide 11, a sealing valve is provided on the interface 15, a magnetic block is provided at the connection between the square through hole 10 and the sealing plate 14, a filter plate 16 is provided at one end of the two groups of fixing blocks 12 close to each other, and water absorption plates are provided on the two groups of slides 11 and the filter plate 16.

[0026] In order to facilitate understanding of the above technical solution of the present invention, the working principle or operation method of the present invention in the actual process is described in detail below.

[0027] In actual application, when the air pressure in the cavity 4 is greater than that in the outside, the sealing plate 14 is stressed and has a tendency to move outward, and then the two groups of spring rods 13 are stretched by force, so that the sealing plate 14 is separated from the square through hole 10, and then the inside and the outside are connected, so that the internal airflow flows outward, thereby ensuring that the pressure inside and outside is consistent; when the air pressure in the cavity 4 is less than the outside air pressure, the sealing plate 14 is subjected to the pressure of the outside air pressure and has a tendency to move inward, thereby squeezing the two groups of spring rods 13 to shrink, and then the sealing plate 14 moves inward until the slide groove 11 is connected with the outside, promoting the airflow input; after the air pressure is balanced, the spring rod 13 returns to its original state, and the sealing plate 14 and the square through hole 10 continue to restore the sealed state. In this process, the air pressure can also be balanced by injecting inert gas into the cavity 4 (or measuring how long the inert gas will decrease and how much it will be through the existing technology and then replenishing it regularly). At the same time, the sealing plate 14 and the spring rod 13 can be separated, and the internal water absorption plate can be replaced regularly.

[0028] In summary, with the aid of the above technical solution of the utility model, the pressure can be automatically balanced through the balancing mechanism, and in this process, no staff intervention is required at all. At the same time, the interface 15 can be connected to the relevant inert gas inflator to regularly and quantitatively inject inert gas into the cavity 4 to ensure that the inert gas content in the cavity 4 is maintained within a certain range, thereby maintaining a certain equilibrium state.

[0029] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
