[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 One embodiment provided by this utility model:

[0023] A drawer-type pneumatic shielding box includes a shielding box body 1, a drawer body 11 slidably connected to the surface of the shielding box body 1, and a removal mechanism provided on the surface of the shielding box body 1. The removal mechanism includes a guide rail 2, which is fixedly connected to the inside of the shielding box body 1. A slide block 21 is slidably connected to the surface of the guide rail 2 and fixedly connected to the side of the drawer body 11. A cylinder 22 is fixedly connected to the inside of the shielding box body 1. A limit ring 23 is fixedly connected to the piston rod of the cylinder 22. A spring 24 is fixedly connected to the surface of the drawer body 11. A limit rod 25 is fixedly connected to the surface of the spring 24. An operating rod 26 is fixedly connected to the surface of the limit rod 25. This removal mechanism can disconnect the connection between the piston end of the cylinder 22 and the drawer body 11, thereby facilitating the removal of the drawer body 11 from the inside of the shielding box body 1, facilitating the operation and maintenance of the drawer body 11, and improving the flexibility of the drawer body 11 during use.

[0024] Furthermore, a raising mechanism is provided at the bottom of the shielding box body 1. The raising mechanism includes a raising rod 3, which is rotatably connected to the bottom of the shielding box body 1. A connecting rod 31 is fixedly connected to the surface of the raising rod 3, and a limit bolt 32 is threadedly connected to the surface of the connecting rod 31. A limit block 33 is fixedly connected to the bottom of the shielding box body 1. This raising mechanism can increase the height of the shielding box body 1 during use, thereby facilitating air circulation and helping the shielding box body 1 to dissipate heat better.

[0025] Furthermore, the drawer body 11 slides on the surface of the shielding box body 1 via the guide rail 2 and the slide block 21. The cylinder 22 drives the limiting ring 23 to move via the piston rod. The moving direction of the limiting ring 23 is the same as the moving direction of the cylinder 22. There are two sets of cylinders 22 and limiting rings 23, located on both sides of the drawer body 11.

[0026] Furthermore, a guide groove is provided on the surface of the drawer body 11, and the limiting rod 25 slides on the guide groove of the drawer body 11. The elastic force of the spring 24 acts on the limiting rod 25, and the limiting rod 25 is perforated and connected to the surface of the limiting ring 23. The limiting rod 25 is perforated and connected to the inner ring of the limiting ring 23. Under the elastic force of the spring 24, the stability of the position between the limiting ring 23 and the limiting rod 25 is ensured. The limiting ring 23 drives the drawer body 11 to slide on the surface of the shielding box body 1 through the limiting rod 25. When the limiting rod 25 moves off the limiting ring 23, the drawer body 11 can be moved out of the shielding box body 1.

[0027] Furthermore, a rectangular hole is provided on one side of the guide groove of the drawer body 11, and the operating rod 26 slides on the rectangular hole of the drawer body 11. The limiting rod 25 and the operating rod 26 are perpendicular to each other. The operating rod 26 is located outside the drawer body 11. The operating rod 26 can drive the limiting rod 25 to slide on the guide groove of the drawer body 11.

[0028] Furthermore, a set of raising rods 3 are respectively provided on both sides of the connecting rod 31. The connecting rod 31 rotates at the bottom of the shielding box body 1 through the raising rods 3. The raising rods 3 are in an "L" shape. When the raising rods 3 are perpendicular to the horizontal plane, they can support the shielding box body 1, thereby increasing the height of the shielding box body 1. When not in use, the raising rods 3 can be folded at the bottom of the shielding box body 1 to save storage space.

[0029] Furthermore, the surface of the connecting rod 31 is provided with a threaded hole, and the limiting bolt 32 is threadedly connected to the threaded hole of the connecting rod 31. The surface of the limiting block 33 is provided with two sets of limiting holes, and the two sets of limiting holes are perpendicular to each other and form a "+" shape on the limiting block 33. The limiting bolt 32 is inserted into the limiting hole of the limiting block 33. The limiting block 33 restricts the angle of the connecting rod 31 and the shim rod 3 at the bottom of the shielding box body 1 through the limiting bolt 32. The connecting rod 31 drives the limiting bolt 32 to rotate synchronously. The limiting bolt 32 can be inserted into the limiting hole of the other set of limiting blocks 33 by rotation.

[0030] Working principle: Slide the operating lever 26 on the surface of the drawer body 11, so that the operating lever 26 drives the limiting lever 25 to compress the spring 24, causing the limiting lever 25 to slide out from the inner ring of the limiting ring 23. At this time, the limiting lever 25 is disengaged from the limiting ring 23, and the drawer body 11 slides inside the shielding box body 1 through the guide rail 2 and the slide block 21. At this time, the drawer body 11 can be slid directly out from inside the shielding box body 1, which facilitates the operation and maintenance of the drawer body 11 and improves the flexibility of the drawer body 11 during use.

[0031] Rotate the shim rod 3 90 degrees at the bottom of the shielding box body 1 so that the shim rod 3 is perpendicular to the horizontal plane. The shim rod 3 drives the connecting rod 31 to rotate, and the connecting rod 31 drives the limiting bolt 32 to rotate. At this time, the limiting bolt 32 is aligned with the limiting hole at the bottom of the limiting block 33. Rotate the limiting bolt 32 on the connecting rod 31 so that the limiting bolt 32 is inserted into the limiting hole of the limiting block 33. At this time, the limiting block 33 restricts the angle of the connecting rod 31 and the shim rod 3 at the bottom of the shielding box body 1 through the limiting bolt 32. The shim rod 3 supports the shielding box body 1 and raises the horizontal height of the shielding box body 1, thereby facilitating air circulation and helping the shielding box body 1 to dissipate heat better.
