[0019] The following is combined with Figure 1-4 This application is described in further detail.

[0020] The present application embodiment discloses a safety device for installing and maintaining an air conditioner outdoor unit, referring to Figure 1, including a safety belt 1, a rope box 2 is provided at the rear end of the safety belt 1, a mounting plate 3 is fixedly connected to the front outer wall of the rope box 2, the upper and lower ends of the mounting plate 3 are provided with a certain elasticity, which can facilitate the installation of the rope box 2, the outer wall of the mounting plate 3 is fixedly connected to the safety belt 1, the inner wall of the rope box 2 is rotatably connected to a winding shaft 4, and a safety rope 5 can be placed. The outer wall of the winding shaft 4 is fixedly connected to the safety rope 5, and the other end of the safety rope 5 is provided with a buckle, which is convenient for the buckle to fix the safety rope 5, and a ratchet 7 is fixedly connected to one side of the winding shaft 4. A fixing plate 8 is slidably connected to the outer wall of one side of the box 2, and a plurality of clamping blocks 9 are fixedly connected to the body of the fixing plate 8. The clamping blocks 9 can abut against the surface of the ratchet 7 to prevent the ratchet 7 from rotating. A cam 13 is rotatably connected to the outer wall of one side of the rope collecting box 2, and the outer wall of the cam 13 is slidably connected to the fixing plate 8. A sticker 14 is fixedly connected to the body of the fixing plate 8 and one side of the rope collecting box 2. The sticker 14 can limit the protrusion of the cam 13. At the same time, the sticker 14 and the protrusion of the cam 13 are provided with magnets that attract each other, so that the fixing plate 8 can be fixed conveniently.

[0021] Reference Figure 3 Two sliding rods 10 are fixedly connected to the outer wall of one side of the rope collecting box 2, and the rod body of the sliding rod 10 is slidably connected with a sliding sleeve 11. The outer wall of the fixed plate 8 is fixedly connected to the two sliding sleeves 11, and the rod body of the sliding rod 10 is sleeved with a spring 12. The spring 12 can push the sliding sleeve 11 to slide on the rod body of the sliding rod 10, so that the protrusion of the cam 13 is no longer in contact with the fixed plate 8, and the block 9 is driven away from the surface of the ratchet 7.

[0022] Reference Figure 2 The outer wall of the winding shaft 4 is fixedly connected with a coil spring 6, and the other end of the coil spring 6 is fixedly connected to the rope collection box 2. The coil spring 6 can drive the winding shaft 4 to rotate when the clamping block 9 no longer fixes the ratchet 7, thereby recovering the safety rope 5.

[0023] Reference Figure 4 The inner wall of the rope receiving box 2 is provided with a rotating frame 15, and the inner wall of the rotating frame 15 is rotatably connected with a pressure shaft 16. The outer wall of the pressure shaft 16 is slidably connected to the safety rope 5. The pressure shaft 16 can fit the surface of the safety rope 5 on the winding shaft 4 to prevent the safety rope 5 from being entangled during rotation.

[0024] Reference Figure 4 The outer wall of the rotating frame 15 is slidably connected with two positioning rods 17, the rod body of the positioning rod 17 is fixedly connected to the rope receiving box 2, and the rod body of the positioning rod 17 is sleeved with a spring 2 18. Under the elastic force of the spring 2 18, the pressure shaft 16 can be attached to the surface of the safety rope 5 on the winding shaft 4.

[0025] The implementation principle of the safety device for installing and maintaining the outdoor unit of an air conditioner in the embodiment of the present application is as follows: when in use, the safety rope 5 can be pulled according to needs, and the safety rope 5 can drive the winding shaft 4 to rotate when being pulled. After the length of the safety rope 5 is adjusted, the cam 13 can be rotated by the rotating sleeve on the surface of the cam 13, so that the protrusion of the cam 13 can be pressed against the fixed plate 8 for movement, so that the block 9 can be pressed against the surface of the ratchet 7, so as to fix the position of the winding shaft 4. At the same time, when the safety rope 5 is pulled out, the rotating frame 15 can be pushed to move under the elastic force of the spring 2 18, so that the pressing shaft 16 can be fitted on the surface of the safety rope 5, and the safety rope 5 can be fitted when rotating to prevent the safety rope 5 from being entangled. Then the safety belt 1 can be worn, and the buckle at the other end of the safety rope 5 can be fixed to external objects, so as to protect the workers.
