When it is necessary to transport the air conditioner 000 from the prototype room to the test bench for installation and testing, the specific process is as follows: drive the lifting bracket 300 through the drive assembly 400, adjust the support plate 200 to a lower height, and place the air conditioner 000 on the support Then push the liftable carrier and transport it to an appropriate location in the laboratory; then adjust the support plate 200 to an appropriate height (the height that matches the experimental bench) through the drive assembly 400, and move the air conditioner 000 to The experimental bench completes the delivery process of the air conditioner 000. In addition, after the installation test is completed, the delivery process of the air conditioner 000 is reversed to the above process.

As shown in Fig. 1, as a possible implementation, the above-mentioned elevating support 300 includes a first support plate 310 and a second support plate 320; wherein, the first support plate 310 and the second support plate 320 are intersected in an "X" structure , and both the first support plate 310 and the second support plate 320 can rotate around their cross axis. During the lifting adjustment, the drive assembly 400 can drive the first support plate 310 and the second support plate 320 to rotate, so that the intersection angle Φ of the first support plate 310 and the second support plate 320 changes. After the intersection angle Φ changes , the height of the support plate 200 connected to the lifting bracket 300 also changes accordingly, so as to achieve the purpose of lifting adjustment.

Further, a roller 322 is disposed on the second free end of the second support plate 320 , and the second free end is in contact with the support plate 200 through the roller 322 . When performing lifting adjustment, the second free end moves on the lower surface of the support plate 200, since the support plate 200 is supported by the first fixed end of the first support plate 310 and the second free end of the second support plate 320, therefore , during the moving process of the second free end, a large dynamic friction force will be generated, and the existence of the roller 322 greatly reduces the friction force, which facilitates the adjustment, and at the same time effectively reduces the movement of the support plate 200 and the second free end during the lifting process. of friction and wear.

1 and 2, as a possible implementation, the drive assembly 400 includes a first sprocket 410, a second sprocket 420, a turntable 430 and a rotating handle 440; the first sprocket 410 is installed on the screw 500, the second The sprocket 420 is installed directly above the first sprocket 410, and the first sprocket 410 and the second sprocket 420 are connected by a chain 450; When performing lifting adjustment, the specific process is: rotate the handle 440 to drive the second sprocket 420 to rotate, the second sprocket 420 drives the first sprocket 410 to rotate through the chain 450, and at the same time, the first sprocket 410 drives the screw 500 to rotate , and then drive the nut 312 to move. Taking the placement position in FIG. Ascending, when the nut 312 moves to the right, the intersection angle Φ between the first support plate 310 and the second support plate 320 becomes larger, and the lifting bracket 300 drives the support plate 200 to descend. It should be noted that the left and right movement of the nut 312 can be adjusted by turning the handle 440 clockwise or counterclockwise.

In addition, the driving assembly 400 can also use a motor. When in use, the motor is connected to one end of the screw 500 , and the rotation of the screw 500 is driven by the operation of the motor.
