[0033] See also Figure 1-Figure 4 As shown, a technical solution provided by the utility model:

[0034] An electromagnetic shielding room, comprising:

[0035] A bottom plate 1, an electromagnetic shielding room body 2 is fixedly installed on the top surface of the bottom plate 1, two bottom grooves 3 are provided on the bottom surface of the bottom plate 1, a lifting plate 4 is provided in each of the two bottom grooves 3, and a plurality of supporting legs 5 are fixedly installed at the bottom ends of the two lifting plates 4;

[0036] Two groups of adjustment components are respectively arranged in the two bottom grooves 3 and are used to drive the two lifting plates 4 to move. The adjustment components include two moving seats 6, which are slidably installed on the inner top surface of the bottom groove 3. Two fixed seats 7 are fixedly installed on the top surface of the lifting plate 4. Connecting rods 8 are rotatably installed in the two fixed seats 7. The top ends of the two connecting rods 8 are rotatably installed in the two moving seats 6 respectively. A screw rod 18 is rotatably installed in the bottom groove 3. One end of the screw rod 18 passes through the bottom groove 3 and extends to the outside of the bottom plate 1. The screw rod 18 is provided with two sections of threads with opposite rotation directions. The two moving seats 6 are threadedly connected with the screw rod 18.

[0037] Two sets of limiting components, the two sets of limiting components are respectively arranged on the two screw rods 18 and are used to limit the screw rods 18;

[0038] A plurality of L-shaped grooves 9, the plurality of L-shaped grooves 9 are respectively provided on both sides of the bottom plate 1, a plurality of L-shaped tubes 10 are rotatably installed in the plurality of L-shaped grooves 9, and an adjustment column 11 is slidably installed in the plurality of L-shaped tubes 10;

[0039] Multiple sets of locking components are respectively arranged on multiple L-shaped tubes 10 and are used to limit the adjustment column 11.

[0040] In this embodiment, the limit assembly includes a limit plate 19, which is fixedly mounted on the screw rod 18. A plurality of first limit holes 20 are provided on the limit plate 19, and a plurality of second limit holes 21 are provided on one side of the base plate 1. One of the first limit holes 20 and one of the second limit holes 21 are movably connected with the same insertion rod 22. After the support leg 5 contacts the ground, the insertion rod 22 is connected to the corresponding first limit hole 20 and the second limit hole 21. At this time, the screw rod 18 will be limited. When the screw rod 18 is limited, the height of the support leg 5 will also be limited, thereby enhancing the stability of the support leg 5 when it contacts the ground.

[0041] In this embodiment, the locking assembly includes a plurality of first threaded holes 12, and the plurality of first threaded holes 12 are opened on one side of the adjusting column 11. A second threaded hole 13 is opened on one side of the L-shaped tube 10. The second threaded hole 13 is internally threadedly connected to the first threaded hole 12 by a bolt 14. When the bottom end of the adjusting column 11 contacts the ground, the bolt 14 can be rotated to lock the adjusting column 11, thereby further enhancing the stability of the base plate 1 when it is placed, in order to prevent the L-shaped tube 10 from moving.

[0042] In this embodiment, multiple side sleeves 15 are fixedly installed on both sides of the base plate 1. The multiple side sleeves 15 correspond to the positions of the multiple L-shaped tubes 10. The tops of the multiple L-shaped tubes 10 are each provided with a sleeve hole 16. The sleeve hole 16 and the side sleeve 15 are movably sleeved with the same pin 17, and the pin 17 is located on one side of the L-shaped groove 9.

[0043] In this embodiment, an adjustment block 24 is fixedly mounted on one end of the screw rod 18 , and the adjustment block 24 is used to conveniently drive the screw rod 18 to rotate.

[0044] In this embodiment, universal wheels 23 are provided at the four corners of the bottom surface of the bottom plate 1 , and the bottom plate 1 can be conveniently moved by the universal wheels 23 .

[0045] In this embodiment, the bottom ends of the multiple support legs 5 and the multiple adjustment columns 11 are provided with anti-slip grooves. When the support legs 5 and the adjustment columns 11 are in contact with the ground, the anti-slip grooves will enhance the anti-slip properties when in contact with the ground and improve the grip.

[0046] In this embodiment, the specifications of the L-shaped tube 10 match the specifications of the L-shaped groove 9. When the adjustment column 11 is not in use, the L-shaped tube 10 can be rotated to be stored in the L-shaped groove 9. After the L-shaped tube 10 is stored in the L-shaped groove 9, the latch 17 is located on one side of the L-shaped groove 9, which will also block the L-shaped tube 10, thereby preventing the L-shaped tube 10 from moving out of the L-shaped groove 9.

[0047] When the electromagnetic shielding room of this embodiment is in use, when the electromagnetic shielding room body 2 is parked, the screw rod 18 is rotated, and when the screw rod 18 is rotated, the two movable seats 6 are driven to move. When the two movable seats 6 move, the two connecting rods 8 and the two fixed seats 7 cooperate to drive the lifting plate 4 to descend. When the lifting plate 4 descends to a certain height, the supporting legs 5 will contact the ground, thereby enhancing the stability of the base plate 1 when parked. After the supporting legs 5 contact the ground, the insertion rod 22 is sleeved in the corresponding first limiting hole 20 and the second limiting hole 21, and the screw rod 18 is limited at this time. When the screw rod 18 is limited, the height of the supporting legs 5 will also be limited, thereby enhancing the stability of the supporting legs 5 when in contact with the ground.

[0048] When the electromagnetic shielding room body 2 is parked, the height of the adjusting column 11 can be adjusted. When the bottom end of the adjusting column 11 contacts the ground, the bolt 14 can be rotated to lock the adjusting column 11, thereby further enhancing the stability of the bottom plate 1 when it is placed. In order to prevent the L-shaped tube 10 from moving, the pin 17 can be sleeved in the corresponding side sleeve 15 and the sleeve hole 16. At this time, the L-shaped tube 10 can be limited, thereby improving the stability of the adjusting column 11 when it contacts the ground. The adjusting column 11 and the supporting leg 5 are in contact with the ground, thereby further enhancing the stability of the bottom plate 1 when it is placed, which is more practical.
