The four rotating grooves are respectively and fixedly sleeved with bearings, and the outer rings of the four bearings are respectively and fixedly connected with the inner walls of the four rotating grooves, so that the rotating rod 5 can rotate more stably on the sliding block 10 through the bearings. The two rotating rods 5 are respectively and fixedly sleeved with rotating squeezing rollers 6. In order to increase the friction between the rotating squeezing rollers 6 and the power cord 14, and thus to make the storage of the power cord 14 more stable, the two rotating squeezing rollers 6 are respectively and fixedly sleeved with a plurality of anti-slip protrusions. The two rotating rods 5 are respectively and movably sleeved with two torsion springs 11. In order to improve the torsion spring 11 and the compression spring The service life of the spring 4 is prolonged, the surfaces of the torsion spring 11 and the compression spring 4 are tin-plated, and one end of the four torsion springs 11 is fixedly connected to the corresponding rotating extrusion roller 6, and the other ends of the four torsion springs 11 are fixedly connected to the corresponding sliding blocks 10, two limiting rings 12 are arranged in the fixed box 2, and the power cord 14 on the multi-chamber room temperature and humidity test box body 1 passes through the two limiting rings 12 and is slidably connected to the two limiting rings 12, two mounting rods 13 are fixedly installed on the two limiting rings 12, and the four mounting rods 13 are fixedly connected to the inner wall of the fixed box 2.

[0023] In order to ensure that the rotating extrusion roller 6 is stably maintained at the current position and cannot rotate, so that the power cord 14 is always stably maintained at the current length and connected to the external socket, a rotating screw 7 is threadedly installed on the fixed box 2, and an arc-shaped extrusion plate 9 is rotatably installed on the bottom end of the rotating screw 7. An arc-shaped rubber friction plate 16 is fixedly installed on the bottom of the arc-shaped extrusion plate 9, and a rotating handle 8 is fixedly installed on the top of the rotating screw 7, and an anti-slip sleeve is fixed on the rotating handle 8.

[0024] In order to limit the arc-shaped extrusion plate 9 and thereby make the movement of the arc-shaped extrusion plate 9 more stable, two stabilizing rods 15 are slidably mounted on the fixed box 2 , and the two stabilizing rods 15 are fixedly connected to the arc-shaped extrusion plate 9 .

[0025] The working principle of the multi-chamber room temperature and humidity test box provided by the utility model is as follows: in the initial state, the compression spring 4 is in a compressed state, the torsion spring 11 is in a free state, the arc-shaped rubber friction plate 16 is not in contact with the rotating extrusion roller 6, and the two rotating extrusion rollers 6 are always tightly squeezed with the power cord 14 through the compression spring 4. When people need to use the device, the device is first moved to a suitable position, and the staff pulls one end of the power cord 14 to move the power cord 14 out of the fixed box 2. The movement of the power cord 14 drives the two rotating extrusion rollers 6 to rotate under the action of friction. The rotation of the rotating extrusion roller 6 causes the torsion spring 11 to change from a free state to a stressed state. When the part of the power cord 14 outside the fixed box 2 reaches a suitable length, the rotating handle 8 is rotated clockwise, and the rotation of the rotating handle 8 drives the rotating screw 7 to rotate and move downward, and the rotating screw 7 moves downward to drive the arc-shaped extrusion plate 9 and the arc-shaped rubber The friction plate 16 moves downward to squeeze the rotating squeezing roller 6 located above, so that the rotating squeezing roller 6 is stably maintained at the current position and cannot rotate, so that the power cord 14 is always stably maintained at the current length and connected to the external socket, thereby providing power to the multi-chamber room temperature and humidity test box body 1, so that the multi-chamber room temperature and humidity test box body 1 can work normally. When people carry the device, they rotate the rotating handle 8 counterclockwise to drive the arc-shaped rubber friction plate 16 to move upward and separate from the rotating squeezing roller 6. At this moment, the rotating squeezing roller 6 changes from the squeeze limit state to the free state, and the torsion spring 11 changes from the force state to the free state. The torsion spring 11 drives the rotating squeezing roller 6 to rotate, and the rotating squeezing roller 6 rotates to drive the power cord 14 to move, and then the power cord 14 is quickly stored in the fixed box 2, so as to prevent the power cord 14 from swinging randomly when people carry the device and affecting the work efficiency of the transportation.

[0026] Compared with the related art, the multi-chamber room temperature and humidity test box provided by the utility model has the following beneficial effects:

[0027] The utility model provides a multi-chamber room temperature and humidity test box. When a staff member pulls one end of a power cord 14, the power cord 14 moves, which causes the torsion spring 11 to change from a free state to a stressed state. When the portion of the power cord 14 outside the fixed box 2 reaches a suitable length, the handle 8 is rotated to drive the arc-shaped rubber friction plate 16 to move downward to squeeze the rotating extrusion roller 6 located above, so that the rotating extrusion roller 6 and the power cord 14 are always stably maintained at the current length and connected to the external socket, thereby providing power for the multi-chamber room temperature and humidity test box body 1. When people carry the device, the handle 8 is rotated counterclockwise to drive the arc-shaped rubber friction plate 16 to move upward and separate from the rotating extrusion roller 6, and the torsion spring 11 changes from a stressed state to a free state, driving the rotating extrusion roller 6 to rotate so that the power cord 14 moves, and then the power cord 14 is quickly stored in the fixed box 2, so as to prevent the power cord 14 from swinging randomly when people carry the device, thereby affecting the work efficiency of the carrying.
