DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] Embodiment 1: Please refer to Figure 1-Figure 8The present invention provides a technical solution: a wall-mounted air conditioner indoor unit maintenance tool, comprising two side angle steels 1, a load-bearing crossbeam 2 is arranged between the two side angle steels 1, and the load-bearing crossbeam 2 is provided with a plurality of first positioning holes 3 arranged in a linear array along the transverse end, and the outer surface of the load-bearing crossbeam 2 is slidably connected to two hooks 4, and the rear outer surfaces of the two hooks 4 are movably inserted with a first limiting rod 5, and the first limiting rod 5 is located on one side of the outside of the hook 4 and is fixedly connected with a pull plate, and a first spring 6 is fixedly connected between the pull plate and the hook 4, and the first spring 6 is sleeved on the outside of the first limiting rod 5, specifically, the groove at the back of the indoor unit is hung on the hook 4, and the stabilizing crossbeam 7 supports the indoor unit, and the distance of the hook 4 can be adjusted according to the different grooves on the back of different indoor units. At this time, the pull plate is pulled, and the pull plate drives The first limiting rod 5 falls off from the first positioning hole 3 and causes the first spring 6 to stretch. At this time, force is applied to the hook 4 to make the hook 4 slide on the stressed cross beam 2. After the hook 4 is moved to a suitable position on the cross beam, the force applied to the pull plate stops, so that the first spring 6 is reset. The first spring 6 drives the first limiting rod 5 to be inserted into the first positioning hole 3, limiting the hook 4 to a suitable position, thereby ensuring that the air conditioner indoor unit is in a vertical and horizontal state, allowing the condensed water of the indoor unit to fall naturally, which is conducive to the unobstructed opening of the air outlet grille of the air conditioner, and is convenient for workers to disassemble, repair and debug. In addition, since the indoor unit hook 4 on the maintenance bracket can be moved left and right and adjusted, it meets the requirements of fixing indoor units of different models on the maintenance bracket. By increasing the number of stressed cross beams 2 and stabilizing cross beams 7, multiple air conditioner indoor units can be supported and repaired at the same time.

[0020] In this embodiment, a stabilizing crossbeam 7 is arranged between the two side angle steels 1, and a plurality of second positioning holes arranged in a linear array are opened along the vertical ends of the two side angle steels 1. The rear outer surface of the stabilizing crossbeam 7 is fixedly connected to two side plates 8 arranged symmetrically on the left and right. A second limiting rod 9 is movably inserted on the outer surface of the side plate 8. The end of the second limiting rod 9 away from the first positioning hole 3 is fixedly connected to a lever 10. A disc 11 is fixedly sleeved on the outer surface of the second limiting rod 9. A second spring 12 is fixedly connected between the disc 11 and the side plate 8. Specifically, according to different sizes of the internal machine, the adjustment The position of the stabilizing beam 7 is adjusted. At this time, the two levers 10 are squeezed toward the middle and at the same time, so that the two levers 10 respectively drive the two second limiting rods 9 to disengage from the second positioning holes, and the second springs 12 are stretched, thereby releasing the limiting of the stabilizing beam 7, and adjusting the position of the stabilizing beam 7. When the second limiting rods 9 correspond to the corresponding second positioning holes, stop applying force to the lever 10, so that the elastic force of the second spring 12 drives the second limiting rod 9 to be inserted into the second positioning hole, and the stabilizing beam 7 is limited, so that the fuselage of the inner machine is supported by the stabilizing beam 7.

[0021] In this embodiment, the bottom outer surfaces of the two side angle steels 1 are fixedly connected with supporting angle steels 17, and stabilizing angle steels 18 are fixedly connected between the two sides of the two side angle steels 1 and the supporting angle steels 17. Specifically, the supporting angle steels 17 and the stabilizing angle steels 18 keep the tooling in a stable state.

The gear 19 is movably engaged with the outer surface of the rack 20. Specifically, when the position of the side angle steel 1 is adjusted, the gear 19 is moved on the outer surface of the rack 20. The meshing force between the rack 20 and the gear 19 can prevent the side angle steel 1 from moving downward directly due to gravity after the limit is released.

[0024] In the specific implementation process, the groove on the back of the inner machine is hung on the hook 4, and the stable beam 7 supports the inner machine. The distance of the hook 4 can be adjusted according to the different grooves on the back of different inner machines. At this time, the pull plate is pulled, and the pull plate drives the first limit rod 5 to fall off from the first positioning hole 3, and the first spring 6 is stretched. At this time, force is applied to the hook 4 to make the hook 4 slide on the force-bearing beam 2. After the hook 4 is moved to a suitable position on the beam, the force on the pull plate is stopped, so that the first spring 6 is reset, and the first spring 6 drives the first limit rod 5 to insert into the first positioning hole 3, and the hook 4 is limited to a suitable position. According to the different sizes of the inner machines, the position of the stable beam 7 is adjusted. At this time, the two levers 10 are squeezed toward the middle and at the same time, so that the two levers 10 respectively drive the two second limit rods 9 to disengage from the second positioning holes, and make The second spring 12 is stretched, thereby releasing the limit on the stabilizing beam 7 and adjusting the position of the stabilizing beam 7. When the second limit rod 9 corresponds to the corresponding second positioning hole, stop applying force to the lever 10, so that the second limit rod 9 is driven by the elastic force of the second spring 12 to insert into the second positioning hole, and limit the stabilizing beam 7, so that the fuselage of the indoor unit is supported by the stabilizing beam 7, and then the indoor unit of the air conditioner is repaired, thereby ensuring that the indoor unit of the air conditioner is in a vertical and horizontal state, so that the condensed water of the indoor unit falls naturally, which is conducive to the unobstructed opening of the air outlet grille of the air conditioner, and is convenient for workers to disassemble, repair and debug. In addition, since the indoor unit hook 4 on the maintenance bracket can be moved left and right and adjusted, it meets the requirements of fixing indoor units of different models on the maintenance bracket. By increasing the number of force-bearing beams 2 and stabilizing beams 7, multiple indoor units of air conditioners can be supported and repaired at the same time.

[0025] Embodiment 2: Please refer to Figure 1-Figure 8The present invention provides a technical solution: a reinforcing crossbeam is fixedly connected at the top between the two side angle steels 1. Specifically, the stability between the two side angle steels 1 is increased by the reinforcing crossbeam.

Specifically, the length of the telescopic column 14 is adjusted, and the telescopic column 14 is rotated between the first rotating seat 13 and the second rotating seat 15, so that the stabilizing plate 16 is in contact with the ground to support the tooling, thereby further increasing the stability of the tooling and preventing the tooling from tipping over due to the gravity of the air-conditioning indoor unit when repairing the air-conditioning indoor unit.

[0027] In the present embodiment, the telescopic column 14 includes a fixed column and a movable column, the movable column is movably inserted into the interior of the fixed column, and the outer surfaces of the fixed column and the movable column are provided with connecting holes, and the number of connecting holes on the surface of the movable column is several and arranged in a linear array, and the connecting holes corresponding to the fixed column and the movable column are threadedly connected with an adjusting handwheel. Specifically, by unscrewing the adjusting handwheel, the limit between the fixed column and the movable column is released, and the position of the movable column inside the fixed column is adjusted. After the adjustment is completed, the adjusting handwheel is screwed into the connecting holes corresponding to the fixed column and the movable column to limit the fixed column and the movable column, thereby adjusting the length of the telescopic column 14.

At this time, force is applied to the hook 4 to make the hook 4 slide on the force-bearing beam 2. After the hook 4 is moved to a suitable position on the beam, the force applied to the pull plate is stopped, so that the first spring 6 is reset, and the first spring 6 drives the first limiting rod 5 to insert into the first positioning hole 3, and the hook 4 is limited to a suitable position. According to the different sizes of the inner machines, the position of the stabilizing beam 7 is adjusted. At this time, the two levers 10 are squeezed toward the middle and at the same time, so that the two levers 10 respectively drive the two second limiting rods 9 to disengage from the second positioning holes, and The second spring 12 is stretched, thereby releasing the limit on the stabilizing beam 7 and adjusting the position of the stabilizing beam 7. When the second limit rod 9 corresponds to the corresponding second positioning hole, stop applying force to the lever 10, so that the elastic force of the second spring 12 drives the second limit rod 9 to be inserted into the second positioning hole, limiting the stabilizing beam 7, thereby supporting the fuselage of the indoor unit through the stabilizing beam 7, and then repairing the indoor unit of the air conditioner, thereby ensuring that the indoor unit of the air conditioner is in a vertical and horizontal state, allowing condensed water in the indoor unit to fall naturally, which is conducive to the unobstructed opening of the air outlet grille of the air conditioner, and facilitating the workers' disassembly, assembly, maintenance and debugging. In addition, since the indoor unit hook 4 on the maintenance bracket can be moved left and right and adjusted, it meets the requirements of fixing indoor units of different models on the maintenance bracket. By increasing the number of force-bearing beams 2 and stabilizing beams 7, multiple indoor units of air conditioners can be supported and repaired at the same time.

[0030] When supporting, the tooling is kept stable by supporting the angle steel 17 and the stabilizing angle steel 18, and the length of the telescopic column 14 is adjusted, and the telescopic column 14 is rotated between the first rotating seat 13 and the second rotating seat 15, so that the stabilizing plate 16 is in contact with the ground to support the tooling, further increasing the stability of the tooling and preventing the tooling from tipping over due to the gravity of the air-conditioning indoor unit when repairing the air-conditioning indoor unit.
