Description

Technical Field

[0001] The present invention relates to the technical field of outdoor air conditioner installation, and specifically, to an outdoor air conditioner auxiliary installation device and an installation method thereof. Background Art

[0002] Air conditioners are an indispensable part of people's modern life. In summer, air conditioners provide people with coolness. An air conditioner is an air conditioner, which generally mainly includes an indoor unit and an outdoor unit. When installing an air conditioner in a high-rise building, first fix the bracket with expansion bolts, check whether the outdoor unit is horizontal, then fix the outdoor unit on the bracket with bolts, remove the electrical box cover of the outdoor unit, and connect the wires according to the paired numbers in the indoor unit wiring box and the outdoor unit wiring box. Usually, when an air conditioner installer places the outdoor unit of the air conditioner on the bracket, it is necessary to manually lift the outdoor unit to the bracket through a cable or other equipment. This manual method of lifting the outdoor unit through a cable or other equipment is likely to cause the outdoor unit of the air conditioner to collide with the wall and easily damage the machine; In this regard, the "auxiliary frame for outdoor wall installation of an outdoor unit of an air conditioner" disclosed in Chinese Patent (Publication No.: CN113465050B) includes a main frame, a placement housing, a clamping assembly, a ratchet clamping assembly, a stroke extension assembly, an outdoor unit opposite fixing assembly, and a bracket release assembly. The placement housing is fixedly installed on the main frame, the clamping assembly is connected to the main frame in a limited way, the ratchet clamping assembly is arranged on the main frame, the stroke extension assembly is rotatably connected to the main frame, the outdoor unit opposite fixing assembly is arranged on the ratchet clamping assembly, and the bracket release assembly is also arranged on the ratchet clamping assembly. However, in the process of implementing the related technology, the above patent has certain technical defects: 1. Through the action of the tension spring, the toggle movable clamping rod 1 and the movable clamping rod 2 buffer the ratchet teeth, and the purpose is that the rope reel relaxes the rope (this effect can also be achieved by a conventional winch). However, when the outdoor unit of the air conditioner is placed on the grille frame, the rope will be subjected to a large instantaneous tension, and the instantaneous tension received by the rope cannot be released and may break, which poses a certain safety hazard; 2. During the entire installation process, the gravity of the outdoor unit of the air conditioner is completely balanced by the tension of the rope, which makes the rope always in a taut state during the installation process. In the case of long-term use, the performance of the rope will decrease. If there is a lack of maintenance or replacement, the rope may break during use, causing the lifting chute plate to be unable to bear the weight of the outdoor unit and tip over, resulting in a safety accident of the outdoor unit of the air conditioner falling from a height; 3. During the process of the lifting chute plate loading the outdoor air conditioner and descending, the triangular plate pushes the pulley and the moving rod to move relative to each other, causing the two grille frames to slide away from each other and separate from the outdoor air conditioner. This movement mechanism causes the two grille frames to start sliding away from each other before the lifting chute plate contacts the outdoor bracket, and until the lifting chute plate contacts the outdoor bracket, the two grille frames are completely separated. This makes the supporting area of the two grille frames for the outdoor air conditioner gradually decrease before the outdoor air conditioner reaches the installation position, which easily causes the problem of excessive local pressure on the grille frames and damage. In view of this, the present invention proposes an outdoor air conditioner auxiliary installation device and its installation method. Summary of the Invention

[0013] The present invention also provides an outdoor air conditioner auxiliary installation method, which is realized according to the outdoor air conditioner auxiliary installation device and includes the following steps: S1: First, horizontally place the horizontal frame on the window sill, and then fix the horizontal frame to the window sill through the clamping mechanism; S2: Manually place the air conditioner outdoor unit in the placement frame and support it through the movable support member. During this process, the steel rope is subjected to a large instantaneous tension and exerts pressure on the corresponding pulley, causing the pulley to exert a downward pressure on the corresponding movable block, causing the sleeve rod to move downward and the buffer spring to be compressed to generate a reverse elastic force for buffering. In this way, the instantaneous tension of the steel rope can be released through the contraction of the spring, thereby avoiding the risk of the steel rope breaking due to a large instantaneous tension; S3: After the air conditioner outdoor unit is placed, operate the winch mechanism to slowly release the steel rope outward at a uniform speed, so that the movable bracket moves downward under the action of gravity until the movable bracket contacts the outdoor bracket. Then, control the movable support member to disengage from the air conditioner outdoor unit, so that the air conditioner outdoor unit slides from the bottom of the placement frame onto the air conditioner installation bracket; S4: Finally, operate the winch mechanism to slowly tighten the steel rope at a uniform speed, so that the movable bracket moves upward to the highest position under the tension of the steel rope, thereby completing the work of installing the air conditioner outdoor unit on the outdoor bracket.

[0014] The working principle and beneficial effects of the present invention are as follows: 1. Manually place the air conditioner outdoor unit in the placement frame and support it through the movable support member. During this process, the steel rope is subjected to a large instantaneous tension and exerts pressure on the corresponding pulley, causing the pulley to exert a downward pressure on the corresponding movable block, causing the sleeve rod to move downward and the buffer spring to be compressed to generate a reverse elastic force for buffering. In this way, the instantaneous tension of the steel rope can be released through the contraction of the spring, thereby avoiding the risk of the steel rope breaking due to a large instantaneous tension; 2. Before installing the outdoor unit of the air conditioner, by controlling the contraction of the output end of the first electric push rod, the connecting plate applies a thrust to the push rod, causing the support plate to move directly below the placement frame, so that the support plate supports the air conditioner outdoor unit after it is placed in the placement frame; when the movable bracket comes into contact with the outdoor bracket with the air conditioner outdoor unit, by controlling the extension of the output end of the first electric push rod, the connecting plate applies a pulling force to the push rod, causing the support plate to be completely misaligned with the placement frame and separated from the air conditioner outdoor unit, so that the air conditioner outdoor unit slides from the bottom of the placement frame onto the air conditioner installation bracket. This process can ensure that the support plate always maintains full support before the air conditioner outdoor unit is installed on the installation bracket, ensuring that the support plate has sufficient support strength and preventing the problem of local overstress and damage to the support plate. 3. When the steel rope breaks during use, at this time the steel rope is completely separated from the movable bracket and no longer bears the gravity of the movable bracket structure system, so that the pulley is not affected by the pressure of the steel rope, the buffer spring releases its potential energy, the movable block drives the movable frame to move upward, and at the same time the torsion spring releases its potential energy, causing the rotating block to drive the pawl to rotate in the reverse direction, so that the pawl cooperates with the tooth groove of the toothed plate, so that the pawl supports the toothed plate, and thus the gravity of the movable bracket structure system is supported by the pawl, which can avoid the problem of the movable bracket losing support and tipping over, causing the air conditioner outdoor unit to fall from a height.

Detailed implementation manners

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present invention. Embodiment

[0019] As Figures 1 - 5As shown in the figure, this embodiment provides an outdoor air conditioner auxiliary installation device, which includes a cross frame 1. One end of the bottom of the cross frame 1 is provided with a clamping mechanism 4 for fixing the cross frame 1 on the window sill. The other end of the bottom of the cross frame 1 is fixedly connected with two parallel vertical frames 2. A movable bracket 5 is slidably connected between the two vertical frames 2. The top of the movable bracket 5 is fixedly connected with a placement frame 6 for placing the outdoor unit of the air conditioner. The bottom end of the placement frame 6 is provided with a movable support member 7 for supporting or disengaging from the outdoor unit of the air conditioner. Steel ropes 8 are fixedly connected to both ends of the movable bracket 5. The top of the cross frame 1 is fixedly connected with a mounting frame 9. The inner side of the mounting frame 9 is provided with a hoisting mechanism 10 for taking in and paying out the steel ropes 8. It is characterized in that two pulley assemblies 11 are arranged at one end of the cross frame 1 close to the vertical frame 2. The pulley assembly 11 includes a fixed seat 111 fixedly connected to the top of the cross frame 1. Movable blocks 112 are slidably connected to both sides of the fixed seat 111. A pulley 113 is rotatably connected between the two movable blocks 112 through a pin shaft. The top end of the pulley 113 abuts against the corresponding steel rope 8. A relief groove 114 corresponding to the pin shaft of the pulley 113 is opened on the side wall of the fixed seat 111. The pin shaft of the pulley 113 is slidably connected to the inner wall of the relief groove 114. Sleeve rods 116 are fixedly connected to the bottoms of the two movable blocks 112. The bottom ends of the two sleeve rods 116 are slidably sleeved with sleeves 115. The bottom ends of the two sleeves 115 are fixedly connected to the fixed seat 111. Buffer springs 117 are sleeved on the two sleeve rods 116. The top ends of the two buffer springs 117 abut against the corresponding movable blocks 112. The bottom ends of the two buffer springs 117 abut against the corresponding sleeves 115. In the initial state, the buffer springs 117 are in a compressed state under the gravity of the movable bracket 5 and the placement frame 6.

[0020] Manually place the outdoor unit of the air conditioner in the placement frame 6 and support it through the movable support member 7. During this process, the steel rope 8 is subjected to a large instantaneous tensile force and exerts a pressure on the corresponding pulley 113, causing the pulley 113 to exert a downward pressure on the corresponding movable block 112, causing the sleeve rod 116 to move downward and the buffer spring 117 to be squeezed to generate a reverse elastic force for buffering. In this way, the instantaneous tensile force of the steel rope 8 can be released through the contraction of the spring, thereby avoiding the risk of the steel rope 8 breaking due to a large instantaneous tensile force.

[0021] Furthermore, the hoisting mechanism 10 includes a rotating shaft 101 rotatably connected to the inner side of the mounting frame 9. Reel wheels 102 for winding the steel ropes 8 are rotatably connected to both ends of the rotating shaft 101. A motor 103 is fixedly installed on the outer side of the mounting frame 9. The output shaft of the motor 103 is fixedly connected to the rotating shaft 101. A battery pack 91 is fixedly installed on the inner side of the mounting frame 9. The motor 103 is electrically connected to the battery pack 91 through a wire.

[0022] The rotating shaft 101 is driven to rotate by starting the motor 103, so that the two winding wheels 102 rotate synchronously. In this way, the winding wheels 102 can wind and unwind the steel rope 8. When the winding wheel 102 unwinds the steel rope 8, the movable bracket 5 moves downward under the action of gravity. When the winding wheel 102 tightens the steel rope 8, the movable bracket 5 is pulled upward by the steel rope 8. In this way, the movable bracket 5 can transfer and install the air conditioner outdoor unit.

[0023] Furthermore, the clamping mechanism 4 includes a fixed bracket 41 fixedly connected to the bottom of the cross frame 1. At both ends inside the cross frame 1, a first chute 43 is provided. A movable plate 42 parallel to the fixed bracket 41 is slidably fitted between the two first chutes 43. One end of the cross frame 1 is threadedly connected with a screw rod 44 passing through the side wall of the cross frame 1. One end of the screw rod 44 is rotatably connected to the movable plate 42, and the other end of the screw rod 44 is fixedly connected with a hand wheel 45.

[0024] Working principle: First, place the cross frame 1 horizontally on the window sill so that the fixed bracket 41 fits against the outer wall of the window sill. Then, manually rotate the hand wheel 45 to drive the screw rod 44 to rotate. After the screw rod 44 rotates relative to the cross frame 1, it will move horizontally and apply a thrust to the movable plate 42, so that the movable plate 42 approaches the window sill and presses against the inner wall of the window sill, making the cross frame 1 stably fixed on the window sill; Then, manually place the air conditioner outdoor unit in the placement frame 6 and support it through the movable support member 7. During this process, the steel rope 8 is subjected to a large instantaneous tension and applies a pressure to the corresponding pulley 113, so that the pulley 113 applies a downward pressure to the corresponding movable block 112, causing the sleeve rod 116 to move downward and the buffer spring 117 to be compressed to generate a reverse elastic force for buffering. In this way, the instantaneous tension of the steel rope 8 can be released through the contraction of the spring, thus avoiding the risk of the steel rope 8 breaking due to a large instantaneous tension; After the air conditioner outdoor unit is placed, start the motor 103 to drive the rotating shaft 101 to rotate, so that the two winding wheels 102 rotate synchronously. When driving the two winding wheels 102 to unwind the steel rope 8, the movable bracket 5 moves downward under the action of gravity until the movable bracket 5 contacts the outdoor bracket. Then, control the movable support member 7 to disengage from the air conditioner outdoor unit, so that the air conditioner outdoor unit slides from the bottom of the placement frame 6 onto the air conditioner installation bracket. The whole process is simple to operate, realizing the rapid installation of the air conditioner outdoor unit. Embodiment

[0025] As Figures 6 - 7As shown in the figure, this embodiment is a further optimization of the outdoor air conditioner auxiliary installation device proposed in Embodiment 1. The only difference from Embodiment 1 is that the movable support 7 includes a support plate 71 arranged at the bottom of the placement frame 6. At both ends inside the movable bracket 5, there are second sliding grooves 72. The two ends of the support plate 71 are respectively slidably connected to the inner walls of the two second sliding grooves 72. One end of the support plate 71 is fixedly connected to a push-pull rod 75, and the end of the push-pull rod 75 is fixedly connected to a connecting plate 74. An electric push rod 73 is fixedly connected to the outer wall of the placement frame 6, and the output end of the electric push rod 73 is fixedly connected to the connecting plate 74. The electric push rod 73 is electrically connected to the battery pack 91 through a wire.

[0026] Before installing the outdoor unit of the air conditioner, by controlling the contraction of the output end of the electric push rod 73, the connecting plate 74 applies a thrust to the push-pull rod 75, causing the support plate 71 to move to directly below the placement frame 6, so that the support plate 71 supports the outdoor unit of the air conditioner after it is placed in the placement frame 6; when the movable bracket 5 contacts the outdoor bracket with the outdoor unit of the air conditioner, by controlling the extension of the output end of the electric push rod 73, the connecting plate 74 applies a pulling force to the push-pull rod 75, causing the support plate 71 to be completely misaligned with the placement frame 6 and separated from the outdoor unit of the air conditioner, so that the outdoor unit of the air conditioner slides from the bottom of the placement frame 6 onto the air conditioner installation bracket. This process can ensure that the support plate 71 always maintains full support before the outdoor unit of the air conditioner is installed on the installation bracket, ensuring that the support plate 71 has sufficient support strength and preventing the problem of local excessive force on the support plate 71 and damage. Embodiment

[0027] As Figures 8 - 9 As shown in the figure, this embodiment is a further optimization of the outdoor air conditioner auxiliary installation device proposed in Embodiment 2. The only difference from Embodiment 2 is that an anti-falling mechanism 12 is provided at one end of the movable bracket 5. The anti-falling mechanism 12 includes a vertical rod 121 vertically fixed at the top end of the movable bracket 5. A toothed plate 122 is fixedly connected to one side of the vertical rod 121. A guide sleeve 123 sleeved outside the vertical rod 121 is fixedly connected to the inside of the cross frame 1. The guide sleeve 123 is slidably connected to the vertical rod 121. A ratchet pawl 124 is rotatably connected to the inside of the guide sleeve 123 through a pin shaft. The ratchet pawl 124 can cooperate with the tooth grooves of the toothed plate 122 through rotation. Rotating blocks 125 are coaxially fixed on both sides of the ratchet pawl 124. A torsion spring 126 is sleeved on the pin shaft of the ratchet pawl 124. One end of the torsion spring 126 is welded to the outer wall of the guide sleeve 123, and the other end of the torsion spring 126 is welded to the rotating block 125. At one end of each of the two rotating blocks 125, there is a pressing member 127 that cooperates with the sliding of the movable block 112 to drive the rotation of the rotating block 125. The initial state of the ratchet pawl 124 is separated from the tooth grooves of the toothed plate 122 and the torsion spring 126 is in a contracted state. The contraction elastic force of the torsion spring 126, the elastic force of the buffer spring 117, and the gravity of the structure system of the movable bracket 5 without load are balanced.

[0028] The pressing member 127 includes a guide seat 1271 fixedly connected to the inner wall of the cross frame 1. One end of the guide seat 1271 is slidably connected with a movable frame 1272 penetrating through the guide seat 1271. The top end of the movable frame 1272 is fixedly connected to the corresponding movable block 112. The bottom end of the movable block 112 is fixedly connected to a connecting shaft 1273. One end of the connecting shaft 1273 is rotatably connected to a connecting rod 1274. The end of the connecting rod 1274 away from the connecting shaft 1273 is rotatably connected to the corresponding rotating block 125.

[0029] Initial state: The steel rope 8 is subjected to the gravity of the structure system of the no-load movable bracket 5, so that the pulley 113 is driven by the steel rope 8 to drive the corresponding movable block 112 to move downward, so that the buffer spring 117 is compressed by a certain displacement. At the same time, the movable frame 1272 moves downward following the movable block 112, so that the connecting shaft 1273 drives the connecting rod 1274 to move downward, so that the rotating block 125 drives the pawl 124 to rotate and disengage from the tooth groove of the toothed plate 122. At this time, the torsion spring 126 contracts and stores elastic potential energy; Loading state: When the air conditioner outdoor unit is placed in the placing frame 6, the gravity of the structure system of the movable bracket 5 increases, so that the compression amount of the buffer spring 117 and the contraction amount of the torsion spring 126 increase; Fracture state: When the steel rope 8 breaks during use, at this time the steel rope 8 is completely separated from the movable bracket 5 and no longer subjected to the gravity of the structure system of the movable bracket 5, so that the pulley 113 is not subjected to the pressure of the steel rope 8, so that the buffer spring 117 releases potential energy, and the movable block 112 drives the movable frame 1272 to move upward. At the same time, the torsion spring 126 releases potential energy to drive the rotating block 125 to drive the pawl 124 to rotate in the reverse direction, so that the pawl 124 cooperates with the tooth groove of the toothed plate 122, so that the pawl 124 supports the toothed plate 122, that is, the gravity of the structure system of the movable bracket 5 is supported by the pawl 124, and further the problem that the movable bracket 5 loses support and overturns, causing the air conditioner outdoor unit to fall from a height can be avoided. Embodiment

[0030] In Embodiment 2 or Embodiment 3, during the process of the placing frame 6 moving downward when loading the air conditioner outdoor unit, the position of the air conditioner outdoor unit may shift, so that after the support plate 71 is separated from the air conditioner outdoor unit, the air conditioner outdoor unit cannot be accurately placed at the corresponding position of the outdoor bracket; Such as Figure 10As shown in the figure, this embodiment is a further optimization of the outdoor air conditioner auxiliary installation equipment proposed in Embodiment 2 or Embodiment 3. The only difference from Embodiment 2 or Embodiment 3 is that a positioning member 61 is provided inside the placement frame 6. The positioning member 61 includes two extrusion rods 611 symmetrically distributed along the midline of the placement frame 6. Both extrusion rods 611 penetrate the side wall of the placement frame 6 and are slidably connected to the placement frame 6. One end of each of the two extrusion rods 611 is fixedly connected to a positioning plate 612, and rubber pads are fixedly connected to the inner sides of the two positioning plates 612. The other end of each of the two extrusion rods 611 is fixedly connected to a wedge-shaped block 613. A return spring 615 is sleeved on each of the two extrusion rods 611. One end of each of the two return springs 615 abuts against the outer wall of the placement frame 6, and the other end of each of the two return springs 615 abuts against the corresponding wedge-shaped block 613. The bottom ends of the two vertical frames 2 are both fixedly connected to a stabilizing plate 3. The distance between the two stabilizing plates 3 is greater than the width of the movable bracket 5. Arc-shaped convex blocks 614 are fixedly connected to the inner sides of the two stabilizing plates 3. The two wedge-shaped blocks 613 are in contact with the corresponding arc-shaped convex blocks 614 by means of the downward movement of the placement frame 6 in cooperation.

[0031] During installation, by starting the motor 103 to drive the rotation of the rotating shaft 101, the two winding wheels 102 rotate synchronously. When the two winding wheels 102 release the steel cable 8 outward, the movable bracket 5 moves downward under the action of gravity. First, the two stabilizing plates 3 contact the outdoor bracket to ensure that the movable bracket 5 can smoothly contact the outdoor bracket. When the movable bracket 5 contacts the outdoor bracket, the two wedge-shaped blocks 613 will contact the arc-shaped convex blocks 614. At this time, the two wedge-shaped blocks 613 move synchronously in opposite directions under the opposite squeezing force. At this time, the two return springs 615 are squeezed to store potential energy, so that the two extrusion rods 611 drive the two positioning plates 612 to move in opposite directions and squeeze and position the outdoor air conditioner in the placement frame 6, so that the outdoor air conditioner is adjusted to the middle position of the placement frame 6. Then, control the output end of the first electric push rod 73 to extend. This causes the connecting plate 74 to apply a pulling force to the push-pull rod 75, so that the support plate 71 is completely misaligned with the placement frame 6 and separated from the outdoor air conditioner. Then start the motor 103 to drive the rotating shaft 101 to rotate in the reverse direction, so that the two winding wheels 102 wind up the steel cable 8, causing the movable bracket 5 to move upward. The two wedge-shaped blocks 613 are separated from the arc-shaped convex blocks 614, and the two return springs 615 release the potential energy, causing the positioning plates 612 to be separated from the outdoor air conditioner. Thus, the outdoor air conditioner can smoothly slide from the bottom of the placement frame 6 to the corresponding installation position on the outdoor bracket, realizing the precise installation of the outdoor air conditioner. Embodiment

[0032] Such as Figures 11 - 12As shown in the figure, the vertical frame 2 includes a fixed part 21 and a movable part 22. The top end of the fixed part 21 is fixedly connected to the horizontal frame 1. The movable part 22 is slidably sleeved outside the fixed part 21. At the top end outside the fixed part 21, an ear seat 23 is fixedly connected. At the bottom of the ear seat 23, an electric push rod 24 is fixedly connected. The output end of the electric push rod 24 is fixedly connected to an ear seat 25. One end of the ear seat 25 is fixedly connected to the movable part 22. The electric push rod 24 is electrically connected to the battery pack 91 through a wire.

[0033] By controlling the electric push rod 24 to drive the movable part 22 to slide relative to the fixed part 21, the overall length of the vertical frame 2 can be adjusted, so that the length of the vertical frame 2 can be flexibly adjusted according to the distance between the outdoor bracket and the window sill, meeting different length requirements in the actual use process.

[0034] Guide members 51 are provided at both ends of the movable bracket 5. The guide members 51 include guide blocks 511 fixedly connected to the ends of the movable bracket 5. The guide blocks 511 are slidably connected to the fixed part 21 or the movable part 22. Elastic rods 512 are fixedly connected to both sides of the guide blocks 511. At one end of the two elastic rods 512, mounting seats 513 are fixedly connected. Inside the two mounting seats 513, rollers 514 are rotatably connected. The rollers 514 are in contact with the inner wall of the fixed part 21 or the movable part 22.

[0035] The rollers 514 can reduce the friction force, enabling the movable bracket 5 to move smoothly inside the vertical frame 2. The design of the elastic rods 512 can ensure a smooth transition when the rollers 514 slide from the fixed part 21 into the inside of the movable part 22, ensuring the stability of the movable bracket 5. Embodiment

[0036] This embodiment provides an outdoor air conditioner auxiliary installation method, which is implemented according to the outdoor air conditioner auxiliary installation equipment of Embodiment 1, and includes the following steps: S1: First, place the horizontal frame 1 horizontally on the window sill, and then fix the horizontal frame 1 to the window sill through the clamping mechanism 4; S2: Manually place the air conditioner outdoor unit in the placement frame 6 and support it through the movable support member 7. During this process, the steel rope 8 is subjected to a large instantaneous tension and exerts a pressure on the corresponding pulley 113, causing the pulley 113 to exert a downward pressure on the corresponding movable block 112, causing the sleeve rod 116 to move downward and the buffer spring 117 to be compressed to generate a reverse elastic force for buffering. In this way, the instantaneous tension of the steel rope 8 can be released through the contraction of the spring, thus avoiding the risk of the steel rope 8 breaking due to a large instantaneous tension. S3: After the outdoor unit of the air conditioner is placed, operate the hoisting mechanism 10 to slowly release the steel rope 8 outward at a uniform speed, so that the movable bracket 5 moves downward under the action of gravity until the movable bracket 5 contacts the outdoor bracket, and then control the movable support 7 to disengage from the outdoor unit of the air conditioner, so that the outdoor unit of the air conditioner slides from the bottom of the placement frame 6 to the air conditioner installation bracket; S4: Finally, operate the hoisting mechanism 10 to slowly tighten the steel rope 8 at a uniform speed, so that the movable bracket 5 moves upward to the highest position under the tension of the steel rope 8, thus completing the work of installing the outdoor unit of the air conditioner on the outdoor bracket.

[0037] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
