It is mainly used in homes, businesses, hotels, schools and other buildings. Air conditioners usually include outdoor units, indoor units and pipelines for connecting the outdoor and indoor units. During the installation of the indoor unit, it is necessary to drill holes in the indoor wall and then install the air conditioner indoor unit and fix it to the inner wall.

[0003] Since the height of the fan installed in the wall-mounted air conditioner is generally higher than the height of the operator, a lifting device is required for auxiliary installation. After searching, the Chinese patent with the publication number CN214935689U discloses an auxiliary device for installing air conditioning ventilation, which specifically relates to the field of air conditioning installation, including a base, the top of the base is fixedly connected with four support columns, the tops of the four support columns are fixedly connected with a bottom plate, the top of the bottom plate is fixedly connected with four telescopic columns, the tops of the four telescopic columns are fixedly connected with a top plate, and the top of the top plate is slidably provided with a support plate for supporting the indoor unit of the air conditioner. The utility model can utilize the rotation of the rotating handle to drive the screw rod to rotate, and the rotation of the screw rod drives the horizontal plate to move up and down. At this time, the limit column on the surface of the horizontal plate moves up and down, and slides on the surface of the sliding rod through the second connecting seat, thereby driving the two connecting rods to approach or move away from each other, and driving the top plate to move upward when the two connecting rods approach each other, thereby adjusting the height of the support plate, so that the fan in the air conditioner can be adjusted to the height required for installation according to needs.

[0004] However, the current lifting equipment has the following deficiencies in actual operation. Most of the current equipment is only used to lift the indoor unit of the air conditioner, which will cause a certain distance between the lifted indoor unit of the air conditioner and the wall. This makes it inconvenient to fix it during installation, resulting in cumbersome operation and increased installation difficulty.

[0039] The lifting unit 100 also includes: a top plate 108 fixedly connected to the top of the side plate 102, a motor A107 arranged on the top of the top plate 108, a threaded rod 105 arranged at the output end of the motor A107, and one end of the threaded rod 105 passes through the top plate 108 and is interconnected with the top of the bottom plate 101, and an internal threaded sleeve block 113 is arranged on the surface of the threaded rod 105, and the internal threaded sleeve block 113 and one end of the mounting back plate 106 are interconnected.

[0040] When the motor A107 is started, it can drive the threaded rod 105 to rotate, and then drive the internal threaded sleeve block 113 to move on the surface of the threaded rod 105, and then drive the installation back plate 106 to move up or down at the front end of the side plate 102, and at the same time make the slider 104 slide on the slide rail 103, and then drive the placement table 111 on the placement base 110 to move up or down synchronously.

[0041] In order to improve the stability of the indoor unit of the air conditioner on the placement platform 111 when it is lifted, Figure 2-5 As shown, the fixing assembly 112 includes: a bidirectional threaded rod 112e rotatably connected to both sides of the inner cavity of the placing platform 111, an internal threaded sleeve block 112f symmetrically threadedly sleeved on the surface of the bidirectional threaded rod 112e, a sliding rod 112c fixedly connected to both ends of the inner cavity of the placing platform 111, a sleeve block 112d symmetrically slidably sleeved on the surface of the sliding rod 112c, three groups of through openings 112b opened on both sides of the top of the placing platform 111, and the internal threaded sleeve block 112f and the sleeve block 112d extend to the top of the placing platform 111 through the through openings 112b, and clamping plates 112a are arranged on both sides above the placing platform 111, and the clamping plates 112a and the internal threaded sleeve block 112f and the top of the sleeve block 112d are connected to each other;

[0042] One end of the bidirectional threaded rod 112 e extends to the outside of the placement platform 111 , and an annular turning handle is provided at one end of the bidirectional threaded rod 112 e located outside the placement platform 111 .

[0043] When the air conditioner indoor unit is placed on the top of the placement platform 111, the two-way threaded rod 112e is driven to rotate by turning the annular handle, and then the two groups of internal threaded blocks 112f are brought close to each other, thereby making the two groups of clamping plates 112a close to each other, and at the same time, the blocks 112d are placed on the surface of the sliding rod 112c, thereby improving the stability of the clamping plates 112a when moving. When the two groups of clamping plates 112a are close to each other, the air conditioner indoor unit above the placement platform 111 can be clamped and fixed, thereby preventing the air conditioner indoor unit from shifting and shaking when the placement platform 111 is lifted, thereby improving the stability of the air conditioner indoor unit when lifted.

[0044] To facilitate the installation of the air conditioner indoor unit on the wall, Figure 3-6 As shown, the collecting unit 400 also includes: two groups of mounting strips 402 fixedly arranged at the bottom of the L-shaped mounting plate 301, multiple groups of fixed sleeve rods 403 sleeved on one side of the mounting strips 402, and the fixed sleeve rods 403 penetrate the two groups of mounting strips 402, a collecting bin 401 fixedly arranged at one end of the fixed sleeve rod 403, a spring 404 sleeved between the two groups of mounting strips 402 on the surface of the fixed sleeve rod 403, a connecting baffle 405 is arranged between the two groups of mounting strips 402, and the connecting baffle 405 is fixedly sleeved on the surface of the fixed sleeve rod 403, and a baffle 406 fixedly connected to the end of the fixed sleeve rod 403 away from the collecting bin 401;

[0045] The mobile unit 300 is arranged in the inner cavity of the placement base 110, including three groups of rectangular slots 302 opened at one end of the placement base 110, a rectangular block 303 slidably sleeved on the inner side of the rectangular slot 302, an electric push rod 304 fixedly arranged at one end of the inner cavity of the rectangular slot 302, the electric push rod 304 extends to the inner cavity of the rectangular block 303, and the output end of the electric push rod 304 and one end of the inner cavity of the rectangular block 303 are connected to each other, and an L-shaped mounting plate 301 is fixedly arranged at one end of the rectangular block 303, and the L-shaped mounting plate 301 and one end of the bottom of the placement table 111 are connected to each other;

[0046] A limiting groove 305 is provided at the bottom of the inner cavity of the rectangular block 303, and the inner side of the limiting groove 305 is slidably connected to the limiting slider 306, and the limiting slider 306 and the bottom of the electric push rod 304 are interconnected, and two sets of auxiliary slide rails are provided on the top of the placement base 110, and an auxiliary slider is provided on the inner side of the auxiliary slide rail and is interconnected with the bottom of the placement table 111.

[0047] Before installing the indoor unit of the air conditioner, it is necessary to drill holes on the designated wall, and then the indoor unit of the air conditioner is conveniently installed on the wall by bolts. First, the operator stands on the top of the placement table 111, and then drives the placement table 111 on the placement base 110 to move to a suitable height by rotating the threaded rod 105, so that the operator can drill holes on the wall. At this time, the three groups of electric push rods 304 are started, and the three groups of electric push rods 304 are used to push the rectangular block 303 to slide out on the inside of the rectangular groove 302. At this time, the limiting slider 306 slides on the inside of the limiting slide groove 305 and supports the electric push rod 304, and at the same time drives the L-shaped mounting plate 301 to move toward the wall on the side with the hole drilled, so that the placement table 111 is close to the wall, and the auxiliary slider moves on the auxiliary slide rail and The platform 111 is supported and limited, and then the elastic force of the spring 404 is used to make the collection bin 401 press against the wall first. As the bottom plate 101 gradually approaches the wall, the collection bin 401 will retreat against the wall, and drive the connecting baffle 405 fixed on the surface of the spring 404 to move and compress the spring 404. When the placement platform 111 moves to the specified position and stops, the collection bin 401 can be closely attached to the wall by the rebound force of the spring 404. Then the operator uses the punching device to punch holes in the wall. At this time, the debris and garbage flowing out of the punching will fall into the collection bin 401 for storage, which effectively prevents the punched debris and garbage from falling to the ground, making it convenient for the debris and garbage to be collected and processed in a centralized manner, greatly reducing the workload of the operator, and also ensuring the cleanliness of the installation operation environment;

[0048] After the holes are punched, the air-conditioner indoor unit is fixedly placed on the top of the placement table 111. Then, the air-conditioner indoor unit can be lifted to a specified height position by rotating the threaded rod 105, and then the three sets of electric push rods 304 are started to push the rectangular block 303 to slide out inside the rectangular notch 302. At this time, the limiting slider 306 slides on the inner side of the limiting slide groove 305 and supports the electric push rod 304, and at the same time drives the L-shaped mounting plate 301 to move toward the wall on the side where the hole is punched, so that the placement table 111 is close to the wall. At this time, the auxiliary slider will move on the auxiliary slide rail and support and limit the placement table 111, and at the same time, the air-conditioner indoor unit on the placement table 111 will fit against the wall, and then it is convenient for the operator to fix the air-conditioner indoor unit to the wall with bolts. After the installation is completed, the two sets of clamping plates 112a can be moved away from each other by rotating the two-way threaded rod 112e in the opposite direction, and then the fixation of the air-conditioner indoor unit can be cancelled, and then the device can be removed.

[0049] Finally, in order to improve the convenience of the device operation, Figure 1 , 2As shown in Figure 7, the rotating unit 200 is arranged at the bottom of the base plate 101, including a rotating base 201 fixedly connected to the bottom of the base plate 101, a rotating disk 202 arranged below the rotating base 201, a motor B206 arranged at the bottom of the rotating disk 202, and the output end of the motor B206 passes through the rotating disk 202 and is interconnected with the bottom of the rotating base 201, and a supporting foot block 203 fixedly connected to both sides of the bottom of the rotating disk 202, an annular groove 204 is arranged on the top of the rotating disk 202, and a plurality of groups of supporting sliders 205 are slidably connected to the inner side of the annular groove 204, and the supporting sliders 205 and the bottom of the rotating base 201 are interconnected, and a ladder 109 is arranged at the bottom of one end of the top plate 108, and the bottom of the ladder 109 and one end of the top of the rotating base 201 are interconnected.

[0050] By starting the motor B206, the rotating base 201 can be driven to rotate, and then the placement table 111 on the rotating base 201 can be driven to rotate, so that the position of the placement table 111 can be rotated and adjusted according to actual installation requirements. At the same time, when installing the air-conditioning indoor unit, the device can be moved to one side of the wall, and the motor B206 can be started to rotate the placement table 111 to move to the side away from the wall, which can increase the operating space near the placement table 111, and then it is convenient for the operator to place the air-conditioning indoor unit on the placement table 111 and fix it. There is no need to place the air-conditioning indoor unit on the placement table 111 of the device first, and then move the device to the side close to the wall for operation, and then start the motor B206 again to drive the air-conditioning indoor unit on the placement table 111 to move to the side close to the wall, and then start the motor A107 to lift the air-conditioning indoor unit on the placement table 111 to a suitable height, and then start the electric push rod 304 to move the air-conditioning indoor unit on the placement table 111 to fit the wall, so as to facilitate the installation operation.
