[0046] Embodiment 2

[0047] Improved on the basis of embodiment 1: Refer to attached Figure 6 The L-shaped groove 25 is L-shaped, which can facilitate the sliding U-shaped plate 14 to move horizontally and vertically inside the device. At the same time, there is friction between the first rectangular block 26 and the L-shaped groove 25, which can be used to reduce the amplitude of vibration. The two baffles 16 penetrate into the interior of the L-shaped groove 25, and one side of the baffle 16 is arc-shaped, which is convenient for the sliding U-shaped plate 14 to enter the interior of the device.

[0048] Embodiment 3

[0049] Improved on the basis of embodiment 1: Refer to attached Figure 1-2 A normal pressure box door 1 is hinged on one side of the normal pressure box body 7, a transparent window 3 is arranged on one side of the normal pressure box door 1, and a pressure difference setting device 2 is arranged on the outer side of the positive pressure box 8.

[0050] The use process and working principle of the technical solution of the present invention are as follows:

[0051] When in use, the positive pressure box 8 drives the sliding U-shaped plate 14 to be inserted into the first rectangular hole 21 horizontally. At this time, the sliding U-shaped plate 14 pushes the two baffles 16 away from each other, and the two baffles 16 drive the two trapezoidal blocks 15 away from each other and stretch the tension spring 17. At this time, the two first rectangular blocks 26 enter the L-shaped groove 25. When the sliding U-shaped plate 14 completely enters the fixed U-shaped plate 12, the positive pressure box 8 is moved vertically downward so that the sliding U-shaped plate 14 falls on the top of the first sliding plate 13. At this time, the two baffles 16 begin to rebound to prevent the sliding U-shaped plate 14 from moving out.

[0052] When the positive pressure box 8 vibrates, the positive pressure box 8 drives the connecting block 18 and the second sliding plate 19 to move horizontally, and the second sliding plate 19 drives the two second rectangular blocks 28 to move inside the rectangular groove 27 and squeeze the first spring 20, which can achieve a buffering function for the horizontal vibration of the positive pressure box 8. At the same time, the first sliding plate 13 moves vertically downward and squeezes the second spring 24, which can buffer the vertical vibration of the positive pressure box 8.

[0053] When the positive pressure box 8 needs to be taken out, the push rod 11 can be pulled horizontally, and the push rod 11 drives the cross plate 10 to move horizontally. The cross plate 10 conflicts with the inclined surfaces of the two trapezoidal blocks 15, and then pushes the two trapezoidal blocks 15 away from each other. The two trapezoidal blocks 15 drive the two baffles 16 away from each other, and thus will not block the L-shaped groove 25. At this time, the positive pressure box 8 can be moved vertically upward and then moved horizontally to be removed from the inside of the L-shaped groove 25, which is convenient to use.

[0054] It should be noted that, in the description of this specification, descriptions such as "first", "second", etc. are merely used to distinguish between various features and have no actual order or directional meaning, and this application is not limited to this.
