[0023] The present utility model will be further described below in conjunction with the accompanying drawings:

[0024] As Figures 1-4 shown, an anti-falling frame for air conditioner maintenance includes a box body 1. Two handles 101 are welded to the front side of the box body 1 to facilitate the movement of maintenance personnel. A storage box 102 for conveniently placing maintenance tools is arranged in the box body 1. A pulley 103 for conveniently storing a safety rope is installed on the front side of the box body 1 through a bracket. A clamping mechanism for preventing shaking is installed on the rear side of the box body 1. Adjusting mechanisms for adjusting the maintenance height are installed at positions near both sides inside the box body 1. A driving mechanism is arranged above the adjusting mechanism, a telescopic mechanism is arranged below the adjusting mechanism, and abutting mechanisms are installed on both sides of the telescopic mechanism.

[0025] The clamping mechanism includes a mounting frame 201, which is welded to the rear side of the box body 1. A threaded pipe 202 is connected to the mounting frame 201 by a key. A threaded rod 203 is threadedly connected to the threaded pipe 202. The front end of the threaded rod 203 is rotatably connected to a clamping plate 204 by a bearing. The rear end of the threaded rod 203 is welded to a turntable 205. The clamping plate 204 is slidably connected to the inner side of the mounting frame 201. By rotating the turntable 205, the threaded rod 203 is driven to rotate and move, and then the clamping plate 204 is driven to move along the mounting frame 201, so as to reduce the distance between the clamping plate 204 and the box body 1, thereby clamping the wall, and further reducing the shaking of the device.

[0026] The driving mechanism includes a motor 401, which is installed on the top of the box body 1 through a bracket. The output shaft of the motor 401 is connected to the top end of the lead screw 301 through a coupling. A first sprocket 402 is connected to the lead screw 301 near the top end by a key. A second sprocket 403 is connected to the other lead screw 301 near the top end by a key. A chain 404 is arranged between the first sprocket 402 and the second sprocket 403. By the movement of the motor 401, the lead screw 301 is driven to rotate. At the same time, by the rotation of the lead screw 301, the first sprocket 402 is driven to rotate, so that the second sprocket 403 is driven to rotate through the chain 404, and then the other lead screw 301 is driven to rotate. The adjusting mechanism includes a lead screw 301, which is rotatably connected to the inner wall of the box body 1 by a bearing. A moving block 302 is threadedly connected to the lead screw 301. A fixing plate 303 is arranged on one side of the lead screw 301, and the fixing plate 303 is connected to the inner wall of the box body 1 by bolts. The moving block 302 is slidably connected to one side of the fixing plate 303. A connecting plate 304 is welded to one side of the moving block 302. The connecting plate 304 is an L-shaped plate made of aluminum alloy, which has a high load-bearing capacity on the premise of reducing weight. During use, by the rotation of the lead screw 301, the moving block 302 is driven to move along the fixing plate 303, so as to adjust the height of the telescopic mechanism, and then adjust the height of the maintenance personnel. During the maintenance process, by the forward and reverse rotation of the motor 401, the moving block 302 is driven to move up and down, so as to drive the telescopic mechanism to move up and down, and then drive the maintenance personnel to move up and down, which is more convenient for maintaining the air conditioner and improves the maintenance efficiency. After use, by the reverse rotation of the motor 401, the moving block 302 is driven to move up, so as to drive the telescopic mechanism to move up, and then reduce the space occupation and facilitate storage.

[0027] The telescopic mechanism includes a bottom plate 501, which is welded to the bottom of the connecting plate 304. A sliding groove 502 is formed in the bottom plate 501. A sliding plate 503 is slidably connected in the sliding groove 502. Fixed blocks 504 are welded to both sides of the sliding plate 503. The tightening mechanism includes a first threaded block 601, which is welded to one side of the bottom plate 501. A first bolt 602 is threadedly connected in the first threaded block 601. A second threaded block 603 is arranged in front of the first threaded block 601. The second threaded block 603 is welded to one side of the bottom plate 501. A second bolt 604 is threadedly connected in the second threaded block 603. During use, by rotating the first bolt 602, the first bolt 602 is rotated upward so that the first bolt 602 no longer obstructs the fixed block 504. Then, the sliding plate 503 is slid out through the fixed block 504 to increase the foot pedal area. Then, by rotating the second bolt 604, the second bolt 604 is rotated downward to tighten the fixed block 504 and prevent sliding during use. After use, by rotating the second bolt 604 upward, the restriction on the second bolt 604 is released. Then, the sliding plate 503 is slid back into the bottom plate 501 by using the fixed block 504. Then, the first bolt 602 is rotated downward to tighten the fixed block 504 and avoid the shaking of the sliding plate 503.

[0028] Working principle: When in use, place the device on both the inside and outside of the wall through the gap between the clamping plate 204 and the box body 1. Then, rotate the turntable 205 to drive the rotation and movement of the threaded rod 203, thereby driving the clamping plate 204 to move along the mounting frame 201, reducing the distance between the clamping plate 204 and the box body 1, thus clamping the wall, reducing the shaking of the device. Then, the motor 401 operates to drive the rotation of the lead screw 301. At the same time, the rotation of the lead screw 301 drives the rotation of the first sprocket 402, and then drives the rotation of the second sprocket 403 through the chain 404, further driving the rotation of another lead screw 301. Through the rotation of the lead screw 301, the moving block 302 is driven to move along the fixed plate 303, thereby adjusting the height of the telescopic mechanism and adjusting the height of the maintenance personnel. Then, rotate the first bolt 602 to rotate it upward, so that the first bolt 602 no longer obstructs the fixed block 504. Then, slide out the sliding plate 503 through the fixed block 504 to increase the foot area. Then, rotate the second bolt 604 to rotate it downward, thereby achieving the tightening of the fixed block 504 to prevent sliding during use. During the maintenance process, the forward and reverse rotation of the motor 401 is used to drive the up and down movement of the moving block 302, thereby driving the up and down movement of the telescopic mechanism and driving the up and down movement of the maintenance personnel, making it more convenient to repair the air conditioner and improving the maintenance efficiency. After use, rotate the second bolt 604 upward to release the restriction on the second bolt 604. Then, use the fixed block 504 to slide the sliding plate 503 back into the bottom plate 501. Then, rotate the first bolt 602 downward to achieve the tightening of the fixed block 504 and avoid the shaking of the sliding plate 503. Then, the motor 401 rotates in reverse to drive the moving block 302 upward, thereby driving the telescopic mechanism upward, reducing the space occupied and facilitating storage.
