[0021] A heating, ventilation and air conditioning indoor unit installation device includes a load-bearing frame 1 and a drawer box 2 that is slideably connected to the inside of the load-bearing frame 1. A connecting plate 301 is fixedly connected to the middle part of the upper side of the load-bearing frame 1. A vertical frame 302 is fixedly connected to the upper side of the connecting plate 301. A guide rod 303 is fixedly connected to the right side of the vertical frame 302. A threaded rod 304 is rotatably connected to the left side of the vertical frame 302. The top of the threaded rod 304 is fixedly connected to the output shaft of the brake motor 306 through a coupling. The brake motor 306 is fixedly connected to the left side of the top of the vertical frame 302 by bolts. The threaded rod 304 The upper thread transmission is connected to the lifting plate 305, and the right side of the lifting plate 305 is slidably connected to the guide rod 303. The middle part of the upper side of the lifting plate 305 is fixedly connected to the annular clamping frame 411, and the inner clamping connection of the annular clamping frame 411 is connected to the annular clamping block 412. The middle part of the annular clamping block 412 is fixedly connected to the vertical rod 413. The middle part of the upper side of the guide rod 303 is provided with a circular hole through which the vertical rod 413 can be protruded. The top of the vertical rod 413 is provided with a placing plate 414, and the inner clamping connection of the placing plate 414 is connected to the connecting plate 415. A plurality of suction cups 5 are fixedly connected to the connecting plate 415.

[0022] A rectangular clamping frame 421 is fixedly connected to the front and rear sides of the lifting plate 305 , respectively. A connecting frame 423 is provided on each rectangular clamping frame 421 , and a standing platform 422 is fixedly connected to each connecting frame 423 .

[0023] This part is based on Figure 1-4The working process expressed therein is: in order to facilitate the solution that the staff need to use an escalator to stand when they want to fix the indoor unit on the ceiling, there is a gap between the escalator and the existing technology, and the staff are prone to stepping on air. When in use, the load-bearing frame 1 can be moved to the position under the ceiling where the indoor unit needs to be installed, and then the indoor unit is placed on the connecting plate 415 through the adsorption of multiple suction cups 5 to ensure the stability of the indoor unit when it is lifted or lowered. The two staff members who are installing the indoor unit stand on two standing platforms 422, and the two standing platforms 422 support the staff members, and then drive the brake motor 306 to rotate the threaded rod 304, thereby The lifting plate 305 connected by the threaded transmission rises under the limit of the guide rod 303, and the two standing platforms 422 are supported by the two clamping frames 421 to move upward with the help of two workers and close to the position where the indoor unit is installed on the ceiling. Compared with the existing technology of installing the indoor unit by escalator, it is safer and more reliable, and reduces the risk of workers stepping on air and falling. At this time, the indoor unit above the connecting plate 415 is supported by multiple suction cups 5 to move close to the position where the indoor unit is installed on the ceiling. After that, the indoor unit is installed and fixed on the required position on the ceiling by workers on both sides. The whole process is simple, efficient, stable and reliable.

[0024] Each of the suction cups 5 is made of rubber.

[0025] This part is based on Figure 1-4 The working process expressed therein is: making each suction cup 5 made of rubber material facilitates improving the adsorption and adhesion of the indoor unit through the suction cup 5, while reducing the risk of the indoor unit shaking greatly during the ascent and thus falling.

[0026] The two standing platforms 422 are arranged in front and back mirror images.

[0027] Each of the standing platforms 422 is an L-shaped structure with a higher outer side.

[0028] This part is based on Figure 1-4 The working process expressed therein is: in order to improve the safety of the workers when each standing platform 422 lifts the workers upward, each standing platform 422 is made into an L-shaped structure with a higher outer side. Therefore, when the workers look up to install, the higher part of the outer side can be supported on the waist and above the back of the workers, preventing the risk of the workers falling outward when looking up, thereby further improving the safety of the overall device.

[0029] A slot is provided on the top of the vertical rod 413 , and the placement plate 414 is connected to the slot by snapping, and the vertical rod 413 is connected to the placement plate 414 by snapping.

[0030] This part is based on Figure 1-4 The working process expressed in the embodiment is that a clamping groove is arranged at the top of the vertical rod 413, so that the placing plate 414 is connected with the clamping groove, the vertical rod 413 is connected with the placing plate 414, and the structure device including the annular clamping block 412, the vertical rod 413 and the structure device above the vertical rod 413 can be disassembled and placed in the drawer 2 for storage at any time after use, and the structure device can be directly installed and used when used later, so that the portability of the device is improved.

[0031] Each of the rectangular clamping frames 421 is connected with the corresponding clamping frame 423.

[0032] The load-bearing frame 1, the connecting plate 301, the vertical frame 302, the lifting plate 305, the annular clamping frame 411, the annular clamping block 412, the vertical rod 413, the placing plate 414 and the clamping plate 415 are on the same vertical central axis.

[0033] This part is according to Figure 1-4 The working process expressed in the embodiment is that the load-bearing frame 1, the connecting plate 301, the vertical frame 302, the lifting plate 305, the annular clamping frame 411, the annular clamping block 412, the vertical rod 413, the placing plate 414 and the clamping plate 415 are on the same vertical central axis, so that these structural components can move in the same vertical direction.

[0034] The top left and right sides of the vertical frame 302 are respectively provided with a spring, and the two sides of the two springs are respectively in contact with the top left and right sides of the vertical frame 302 and the left and right sides of the bottom of the placing plate 414.

[0035] Each of the springs is a compression spring.

[0036] This part is according to Figure 1-4 The working process expressed in the embodiment is that in order to improve the stability of the indoor unit placed on the plurality of suction cups 5 above the clamping plate 415 during the lifting movement, two springs are placed on the top left and right sides of the vertical frame 302, and the two sides of the two springs are respectively fixedly connected with the top left and right sides of the vertical frame 302 and the left and right sides of the bottom of the placing plate 414. By using the rebound force of each compression spring, when the placing plate 414 and the vertical rod 413 are connected with instability, the bottom two sides of the placing plate 414 can be buffered and supported by each spring, so that excessive shaking during the lifting of the indoor unit is prevented, the risk of shaking and falling of the indoor unit is reduced to the greatest extent, and the working stability of the device is further improved.

[0037] Working principle: When in use, first connect the annular clamping block 412 with the annular clamping frame 411, connect the connecting plate 415 with the placement plate 414, connect the placement plate 414 with the vertical pole 413, and adsorb the indoor unit on the suction cup 5. Then the staff stands on the standing platform 422, controls the brake motor 306 to start, and the brake motor 306 reverses to drive the threaded rod 304 to rotate. The threaded rod 304 reverses to drive the lifting plate 305 to move upward. The lifting plate 305 drives the rectangular clamping frame 421 to move upward. The rectangular clamping frame 421 drives the standing platform 422 to move upward through the connecting frame 423.
