[0020] Embodiment: A safety protection device for air conditioner outdoor unit maintenance, see Figure 1-Figure 4 As shown, it includes a support plate 1; the support plate 1 is used to be installed on the outer wall, and the support plate 1 is placed directly below the air conditioner outdoor unit; it also includes a fixing frame 2, a folding cloth I3, a folding cloth II4 and a handle I5; the fixing frames 2 are arranged on the left and right sides of the top of the support plate 1; two folding cloths I3 are symmetrically arranged on the left and right sides of the top of the support plate 1, and the front ends of the two folding cloths I3 are respectively connected to the two fixing frames 2, so that the two folding cloths I3 can be folded forward on the fixing frames 2; the folding cloth II4 is slidably arranged on the front side of the top of the support plate 1, and ... The left end of the cloth II 4 is connected to the fixed frame 2 on the left, and the right end of the folded cloth II 4 is in contact with the fixed frame 2 on the right, so that the folded cloth II 4 can be folded to the left on the fixed frame 2 on the left. The folded cloth I 3 and the folded cloth II 4 are both used to protect the maintenance personnel on the support plate 1, thereby protecting the safety of the maintenance personnel, and can prevent the parts of the air conditioner outdoor unit from falling downward from the edge of the support plate 1 to avoid falling objects from high altitude; handles I 5 are provided on the rear sides of the left and right sides of the two folded cloths I 3, and the handles I 5 are used for the maintenance personnel to pull the folded cloth I 3 to fold and unfold.
[0021] See also Figure 3 and Figure 4 As shown, a roller 6 is also included; a roller 6 is rotatably arranged at the lower rear part of the folding cloth I3, and the roller 6 is used to assist the folding cloth I3 in folding and unfolding.
[0022] See also Figure 2 As shown, an anti-skid pad 7 is also included. The anti-skid pad 7 is arranged on the top of the support plate 1. The anti-skid pad 7 is used to increase the friction between the support plate 1 and the maintenance worker to prevent the maintenance worker from slipping.
[0023] See also Figure 1 , Figure 3 , Figure 4 and Figure 5As shown, it also includes a limiting mechanism, which includes a protrusion 8, a limiting plate 9 and a handle II 11; protrusions 8 are arranged at intervals on the top of the folding cloth I3 and the folding cloth II 4; limiting plates 9 are placed on the top of the folding cloth I3 and the folding cloth II 4; limiting holes 10 are spaced apart on the limiting plate 9, and the number of the limiting holes 10 is consistent with the protrusion 8. The protrusion 8 is inserted into the limiting hole 10, so that the limiting hole 10 limits the folding cloth I3 and the folding cloth II 4 in the unfolded state to prevent the folding cloth I3 and the folding cloth II 4 in the unfolded state from being folded; the handle II 11 is installed on the top of the limiting plate 9, and the handle II 11 is used by the maintenance personnel to lift the limiting plate 9 for removal.
[0024] See also Figure 3-Figure 5 As shown, it also includes a locking mechanism, which includes a connecting plate 12, a locking block 13 and a spring 15; the left side and the front side of the left fixing frame 2 are connected to the connecting plate 12, and the right side of the right fixing frame 2 is also connected to the connecting plate 12; the locking block 13 is slidably installed on the connecting plate 12; the upper rear sides of the two folding cloths I3 away from each other are provided with a locking groove 14, and the upper right side of the front side of the folding cloth II4 is provided with a locking groove 14. By locking the locking block 13 into the locking groove 14, the locking block 13 can limit the folding cloth I3 and the folding cloth II4 in the retracted state to prevent the folding cloth I3 and the folding cloth II4 in the retracted state from unfolding; the two ends of the spring 15 are respectively connected to the connecting plate 12 and the locking block 13, and the spring 15 is used to reset the locking block 13 after it moves.
[0025] When in use, the support plate 1 is installed together with the air-conditioning outdoor unit, so that the support plate 1 is directly below the air-conditioning outdoor unit, and the air-conditioning outdoor unit is between the folding cloth I3 and the folding cloth II4, and then the handle II11 is lifted to lift the limiting plate 9, so that the limiting plate 9 is separated from the folding cloth I3 and the folding cloth II4, and the protrusion 8 is removed from the limiting hole 10, so that the limiting plate 9 releases the limit on the unfolded state of the folding cloth I3 and the folding cloth II4, and then the folding cloth I3 is folded forward by pulling the handle I5 (during this period, the roller 6 will roll on the anti-slip pad 7 to assist the folding cloth I3 to be folded). When the folding cloth I3 contacts the card block 13, the folding cloth I3 will squeeze the card block 13 to move to the side away from each other, and the corresponding spring 15 will be compressed. When the card block 13 is aligned with the card slot 14 on the folding cloth I3, the corresponding spring The spring 15 returns to its original state, and the corresponding spring 15 drives the card block 13 to move and reset to the side close to each other, so that the card block 13 is stuck in the card slot 14 on the folding cloth I3, so that the card block 13 limits the folding cloth I3 in the retracted state, and then pulls the folding cloth II4 to the left for retracting. When the folding cloth II4 contacts the card block 13, the folding cloth II4 will squeeze the card block 13 to move forward, and the corresponding spring 15 is compressed. When the card block 13 is aligned with the card slot 14 on the folding cloth II4, the corresponding spring 15 returns to its original state, and the corresponding spring 15 drives the card block 13 to move and reset backward, so that the card block 13 is stuck in the card slot 14 on the folding cloth II4, so that the card block 13 limits the folding cloth II4 in the retracted state. In this way, the folding cloth I3 and the folding cloth II4 can be retracted to facilitate the operation of the air conditioner outdoor unit;
[0026] When the maintenance worker needs to repair the air conditioner outdoor unit, he only needs to carry the limiting plate 9 and use the safety rope to climb to the edge of the supporting plate 1, then climb onto the supporting plate 1, and then pull the handle Ⅰ5 to unfold the folding cloth Ⅰ3 backward (during this period, the roller 6 will roll on the anti-slip pad 7 to assist the folding cloth Ⅰ3 to unfold). During this period, the folding cloth Ⅰ3 will squeeze the card block 13 to move to the side away from each other, and the corresponding spring 15 will be compressed to release the limit on the folding cloth Ⅰ3 by the card block 13. When the folding cloth Ⅰ3 is separated from the card block 13, the corresponding spring 15 will return to its original state, and the corresponding spring 15 will drive the card block 13 to move to the side close to each other and reset, and then pull the folding cloth Ⅱ4 to the right to unfold. During this period, the folding cloth Ⅱ4 will squeeze the card block 13 to move forward, and the corresponding spring 15 will be compressed to release the limit on the folding cloth Ⅱ4 by the card block 13. When the folding cloth Ⅱ4 is separated from the card block 13 , the corresponding spring 15 returns to its original state, and the corresponding spring 15 drives the card block 13 to move backward and reset, and then the limiting plate 9 is put back on the top of the folding cloth I3 and the folding cloth II4, and the protrusion 8 is re-engaged in the limiting hole 10 of the limiting plate 9, so that the limiting plate 9 limits the unfolded state of the folding cloth I3 and the folding cloth II4, and then the maintenance personnel can stand or sit on the support plate 1 to repair the air-conditioning outdoor unit. During this period, an anti-slip pad 7 is arranged on the support plate 1 to increase the friction between the maintenance personnel and the support plate 1 to prevent the maintenance personnel from slipping; and the support plate 1 is surrounded by the folding cloth I3 and the folding cloth II4 to prevent the detached parts from falling from the edge of the support plate 1 and causing falling objects from high altitude; when the air-conditioning outdoor unit is repaired, the handle II11 is lifted again to lift the limiting plate 9, and then the folding cloth I3 and the folding cloth II4 are put away again, and then the maintenance personnel can leave the support plate 1.
