[0024] like Figures 1 to 3As shown, a lifting rod system for a mobile shielding laboratory includes a base 1, a mounting rod 2 is fixedly connected to the top surface of the base 1, a lifting control assembly 3 is arranged on the surface of the mounting rod 2, a support plate 4 is arranged on the surface of the lifting control assembly 3, a docking assembly 5 for connecting with a shielding room is arranged on the surface of the support plate 4, a fixing frame 6 is fixedly connected to the back of the mounting rod 2, and a limiting assembly 7 for limiting the lifting control assembly 3 is arranged on the surface of the fixing frame 6. More specifically, the upper shielding room is connected through the docking assembly 5, and the support plate 4 and the docking assembly 5 can be driven to move up and down through the lifting control assembly 3, thereby driving the upper shielding room to move and realize the opening and closing of the shielding room, and the operation of the lifting control assembly 3 can be limited through the limiting assembly 7, thereby controlling the range of the up and down movement of the support plate 4 and the docking assembly 5, and realizing the precise control of the height of the docking assembly 5.

[0025] The lifting control assembly 3 includes a motor 301, and the motor 301 is fixedly mounted on the top surface of the mounting rod 2, the output end of the motor 301 is fixedly connected with a threaded column 302, the surface of the threaded column 302 is threadedly connected with a connecting rod 303, and the end of the connecting rod 303 is fixedly connected with the support plate 4, and the surface of the mounting rod 2 is fixedly connected with a sliding column 304, and the sliding column 304 is slidably connected with the connecting rod 303. It should be noted that the threaded column 302 is driven to rotate by the motor 301, and the connecting rod 303 will be driven to slide along the surface of the sliding column 304 under the action of the thread on its surface, thereby driving the support plate 4 and the docking assembly 5 to move, that is, the upper shielding room can be driven to move up and down.

[0026] The docking assembly 5 includes a double-headed screw 501, and the double-headed screw 501 is rotatably connected to the support plate 4, one end of the double-headed screw 501 is fixedly connected to the first knob 502, the surface of the double-headed screw 501 is threadedly connected to the support frame 503, and the support frame 503 is movably plugged with the support plate 4, and the surface of the support frame 503 is fixedly connected to the insertion rod 504. More specifically, by rotating the first knob 502, the double-headed screw 501 can be driven to rotate, and the support frame 503 is driven to move under the action of the thread, and then the insertion rod 504 is driven to move, and a concave hole adapted to the insertion rod 504 is opened on the surface of the upper shielding chamber, and the insertion rod 504 will be inserted into the inner wall of the concave hole, thereby connecting with the upper shielding chamber, and the first knob 502 is rotated in the opposite direction to release the connection with the upper shielding chamber.

[0027] The limit assembly 7 includes an adjusting screw 701, and the adjusting screw 701 is rotatably connected to the fixing frame 6, one end of the adjusting screw 701 is fixedly connected to the second knob 702, the surface of the adjusting screw 701 is threadedly connected to the mounting plate 703, and the mounting plate 703 is fixedly installed with a pressure sensor 705 on the side of the mounting plate 703 close to the connecting rod 303, and the pressure sensor 705 is electrically connected to the motor 301. It should be noted that when the mounting plate 703 moves, it will contact the pressure sensor 705. At this time, the pressure sensor 705 detects the pressure and will feedback control the motor 301 to stop running, so that the connecting rod 303 and the support plate 4 stop moving, so that the height of the upper shielding room can be limited. By turning the second knob 702, the adjusting screw 701 is driven to rotate, and the mounting plate 703 is driven to move up and down under the action of the thread, thereby changing the height of the pressure sensor 705, so that the height of the connecting rod 303 when in contact with the pressure sensor 705 can be controlled.

[0028] There are two groups of limiter assemblies 7, and the two groups of limiter assemblies 7 are symmetrically distributed with the horizontal center line of the front surface of the fixing frame 6 as the symmetry axis.

[0029] The surface of the mounting rod 2 is provided with a limiting groove 704, and the inner wall of the limiting groove 704 is slidably connected to the surface of the mounting plate 703. It should be noted that by providing the limiting groove 704, the mounting plate 703 is limited so that the mounting plate 703 can only slide along the inner wall of the limiting groove 704, thereby preventing the mounting plate 703 from rotating with the adjusting screw 701.

[0030] In summary: the upper shielding room is connected through the docking component 5, the support plate 4 and the docking component 5 can be driven to move up and down through the lifting control component 3, thereby driving the upper shielding room to move and realize the opening and closing of the shielding room, and the operation of the lifting control component 3 can be limited by the limit component 7, thereby controlling the range of up and down movement of the support plate 4 and the docking component 5, and realizing precise control of the height of the docking component 5. In use, it is achieved that the upper and lower separated shielding rooms can be accurately opened and closed, and the upper shielding room can be accurately reached.
