[0025] Example 2
[0026] Refer to Figures 1-5 In the case that other parts are same with example 1, the difference between the utility model and example 1 is that:
[0027] The inner bottom surface of glove box body 1 is equipped with second air bag 12, and second air bag 12 is connected with first air bag 8 through air guide pipe; first air bag 8 and second air bag 12 are both annular, and first air bag 8 and second air bag 12 are both connected with top cover 2 and glove box body 1 through magic tape; the setting of second air bag 12 makes first air bag 8 expand and send gas to second air bag 12 through air guide pipe, that is, makes second air bag 12 and first air bag 8 expand synchronously, thereby further reducing the space inside glove box body 1, and further facilitating the control of the amount of gas inside glove box body 1; the setting of magic tape makes first air bag 8 and second air bag 12 can be conveniently disassembled and replaced; the cylinder body of gas cylinder 3 is equipped with supplement pipe 13 at the lower end in second gas cavity 7, and the pipe body of supplement pipe 13 is equipped with second valve; the setting of supplement pipe 13 facilitates the supplement of gas inside second gas cavity 7, thereby facilitating the control of the expansion degree of first air bag 8 and second air bag 12.
[0028] The end of lower end of air pipe 9 is equipped with filter plate 14, and the outer side of filter plate 14 is connected with top cover 2 through mounting frame; the setting of filter plate 14 facilitates the control of the cleanliness of gas entering the inside of first gas cavity 6, so as to prevent dust from entering first gas cavity 6 and causing great damage to piston 5; the upper end of gas cylinder 3 is equipped with maintenance cover 15, and maintenance cover 15 is connected with gas cylinder 3 through bolt; telescopic part 4 is installed on the plate body of maintenance cover 15; the setting of maintenance cover 15 makes personnel conveniently open gas cylinder 3, that is, facilitates the maintenance of personnel to the parts inside gas cylinder 3, thereby facilitating the maintenance of personnel to the equipment; one end of glove box body 1 is equipped with observation plate, and the other end of glove box body 1 is equipped with hatch; the setting of observation plate and hatch not only facilitates the observation of personnel to the processing condition of parts inside the box body, but also facilitates the taking and placing of personnel.
[0029] Principle and advantages: in the process of using, the glove box main body 1 is used for processing of parts, namely the parts to be processed are placed in the glove box main body 1, personnel are inserted into the glove box through the glove box main body 1 front side setting glove interface disc and other components to process the parts, and in this process, when the parts are processed, the piston 5 is located at the upper end of the gas cylinder 3, namely the gas in the air bag is sucked into the second gas cavity 7, and when the parts are processed and need to be taken, the piston 5 is driven by the telescopic piece 4 to move downwards, namely the gas in the second gas cavity 7 is extruded into the air bag, so that the air bag expands to occupy the internal space of the glove box main body 1, and when the internal space of the glove box main body 1 is occupied, the original part of the inert gas enters the first gas cavity 6 through the communication pipe 10 to store, and then personnel can open the hatch to take and put the parts, and in this process, since part of the inert gas in the internal space of the glove box main body 1 is sucked into the first gas cavity 6, the inert gas in the internal space of the glove box main body 1 is less diffused to the outside through the hatch.
[0030] Further, when the hatch is closed, the parts need to be processed, the inert gas in the first gas cavity 6 is recharged into the internal space of the glove box main body 1 by the upward movement of the piston 5, and the air bag is contracted, so that the inert gas is saved to a certain extent, that is, the waste of inert gas is avoided, and the contracted air bag does not interfere with the processing of the parts, and when the pressure in the internal space of the glove box main body 1 needs to be adjusted, the valve is closed, so that the air in the internal space of the glove box main body 1 cannot enter the first gas cavity 6, and then the expansion and contraction of the air bag can be controlled by the upward and downward movement of the piston 5, and the expansion and contraction of the air bag can adjust the pressure in the internal space of the glove box main body 1.
[0031] In summary, when the scheme is used, the piston 5 moves up and down through the cooperation of the pressure gauge 11 and the gas cylinder 3, which not only has the effect of temporarily storing the inert gas in the internal space of the glove box main body 1, that is, reduces the waste of inert gas, but also can actively control the expansion degree of the air bag, so that the pressure in the internal space of the glove box main body 1 can be controlled by the expansion degree of the air bag, and the precise movement of the piston 5 driven by the telescopic piece 4 makes the scheme compared with the traditional scheme, the internal pressure of the glove box main body 1 can be precisely and quickly adjusted.
[0032] It is further explained that the second air bag 12 is arranged so that the first air bag 8 can be inflated through the air pipe to the second air bag 12, that is, the second air bag 12 is inflated synchronously with the first air bag 8, thereby further reducing the space inside the glove box body 1, and facilitating the control of the amount of gas inside the glove box body 1. The arrangement of the magic tape makes the first air bag 8 and the second air bag 12 convenient to disassemble and replace; the arrangement of the supplementary pipe 13 facilitates the replenishment of the gas inside the second air cavity 7, thereby facilitating the control of the inflation degree of the first air bag 8 and the second air bag 12; the arrangement of the filter plate 14 facilitates the control of the cleanliness of the gas entering the first air cavity 6, so as to prevent dust from entering the first air cavity 6 and causing great damage to the piston 5; the arrangement of the maintenance cover 15 makes it convenient for personnel to open the gas cylinder 3, that is, it is convenient for personnel to overhaul the internal parts of the gas cylinder 3, thereby facilitating personnel to maintain the equipment; the arrangement of the observation plate and the hatch not only facilitates the observation of the processing of the internal parts of the box by the bystanders, but also facilitates the personnel to take and place materials.
[0033] The above is only a preferred embodiment of the present application, but the protection scope of the present application is not limited thereto. Any skilled person in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
