[0002] Most household air conditioners are split-type, consisting of an indoor unit and an outdoor unit. The indoor unit is installed indoors and can change the indoor environment and temperature. Currently, the installation of air conditioner outdoor units mostly relies on installers manually moving the outdoor unit from a height to place it on the bracket. Manually moving and installing the outdoor unit is not only physically demanding but also very dangerous, as it is easy for the unit to slip and fall. Utility Model Content

[0003] The purpose of this utility model is to provide a hoisting device for installing an air conditioner outdoor unit, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a hoisting device for installing an air conditioner outdoor unit, comprising a main frame, the main frame being U-shaped, with the shorter side of the main frame inside the building and the longer side outside the building. A T-shaped groove is provided on the longer side of the main frame, and a T-shaped guide block is slidably disposed within the T-shaped groove. A lifting plate is fixedly installed on the outer wall of the T-shaped guide block. A connecting shaft is rotatably connected to the shorter side of the main frame via a bearing. Rewinding wheels are fixedly installed at both ends of the connecting shaft. A first guide ring and a second guide ring are fixedly installed on the main frame. The second guide ring is located above the lifting plate. A hoisting rope is wound around the rewinding wheel, and the hoisting rope passes through the first guide ring and the second guide ring in sequence before being fixedly connected to the top of the lifting plate. A manual deceleration drive component is installed on the main frame, and the manual deceleration drive component is drively connected to the connecting shaft.

[0005] Furthermore, the manual deceleration drive component includes a fixed housing, which is fixedly mounted on the main frame. The inner wall of the fixed housing is rotatably connected to a rotating shaft via a bearing. One end of the rotating shaft extends out of the fixed housing. A worm gear is fixedly mounted on the outer wall of the rotating shaft. The worm gear meshes with a worm wheel, which is fixedly mounted on a connecting shaft.

[0006] Furthermore, the upper surface of the lifting plate is an inclined surface, and the end of the lifting plate closest to the main frame is the lowest end. An integrally formed anti-fall side plate is provided on the top of the lifting plate.

[0007] Furthermore, a sliding groove is provided on the top of the main frame, a slider is slidably disposed in the sliding groove, a sliding plate is fixedly installed on the top of the slider, and a stop plate is fixedly installed at the bottom of the end of the sliding plate away from the lifting plate, the outer diameter of the stop plate being larger than the inner diameter of the sliding groove.

[0008] Furthermore, a handle and a rectangular locking post are fixedly sleeved on one end of the rotating shaft that extends outside the fixed housing. A handle is movably sleeved on the rectangular locking post, and the outer wall of the handle is provided with anti-slip protrusions.

[0009] Furthermore, a reinforcing plate is fixedly installed on the main frame, and an elastic rubber pad is fixedly laid on the outer wall of the reinforcing plate facing the wall on the side where it is erected.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] 1. The connecting shaft is driven to rotate by a manual deceleration drive component, which in turn drives the winding wheel to rotate, thereby winding and unwinding the hoisting rope. The hoisting rope is used to pull the lifting platform up and down, thus transporting the air conditioner outdoor unit placed on the lifting platform to the corresponding installation height. Workers only need to place the air conditioner outdoor unit on the lifting platform inside the building, eliminating the need for workers to move the air conditioner outdoor unit outside the building. This greatly reduces the workload of workers outside the building and thus reduces the construction risk. The use of a manually rotated manual deceleration drive component instead of a conventionally designed motor drive can significantly reduce the weight and cost of the entire hoisting device.

[0012] 2. By rotating the shaft, the worm gear is driven to rotate, which in turn drives the worm wheel to rotate. The rotation of the worm wheel drives the connecting shaft to rotate. The worm wheel and worm gear transmission can lock the connecting shaft by utilizing their self-locking properties, preventing the lifting plate from continuing to move downward under gravity after being hoisted into place. On the other hand, the high reduction ratio between the worm wheel and worm gear means that not much force is needed to rotate the shaft.

[0013] 3. When moving the outdoor unit of the air conditioner from inside the building to the lifting platform, the outdoor unit can be placed on the sliding platform from inside the building. Then, push the sliding platform until one end of the sliding platform moves above the lifting platform. Then, push the outdoor unit from inside the building to the lifting platform. There is no need for workers to manually flip the outdoor unit over the building. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Please see Figures 1-6 This utility model provides a technical solution: a hoisting device for installing an air conditioner outdoor unit, including a main frame 1, which is U-shaped, with the shorter side of the main frame 1 inside the building and the longer side outside the building. A T-shaped groove is provided on the longer side of the main frame 1, and a T-shaped guide block 3 is slidably arranged in the T-shaped groove. A lifting plate 2 is fixedly installed on the outer wall of the T-shaped guide block 3. A connecting shaft 7 is rotatably connected to the shorter side of the main frame 1 through a bearing. A winding wheel 4 is fixedly installed at both ends of the connecting shaft 7. A guide ring 1 5 and a guide ring 2 6 are fixedly installed on the main frame 1. The guide ring 2 6 is located above the lifting plate 2. A hoisting rope is wound on the winding wheel 4, and the hoisting rope passes through the guide ring 1 5 and the guide ring 2 6 in sequence before connecting with the lifting plate 2. The top of the lifting plate 2 is fixedly connected, and a manual reduction drive component 8 is installed on the main frame 1. The manual reduction drive component 8 is connected to the connecting shaft 7. The manual reduction drive component 8 drives the connecting shaft 7 to rotate, which in turn drives the winding wheel 4 to rotate, thereby winding and unwinding the hoisting rope. The hoisting rope is used to pull the lifting plate 2 up and down, thereby transporting the air conditioner outdoor unit placed on the lifting plate 2 to the corresponding installation height. Workers only need to place the air conditioner outdoor unit on the lifting plate 2 inside the building, eliminating the need for workers to move the air conditioner outdoor unit outside the building. This greatly reduces the workload of workers outside the building and thus reduces the construction risk. The use of a manually rotated manual reduction drive component 8 instead of a conventionally designed motor drive can significantly reduce the weight and cost of the entire hoisting device.

[0023] The manual reduction drive component 8 includes a fixed housing 801, which is fixedly mounted on the main frame 1. The inner wall of the fixed housing 801 is rotatably connected to a rotating shaft 804 via a bearing. One end of the rotating shaft 804 extends out of the fixed housing 801. A worm gear 803 is fixedly mounted on the outer wall of the rotating shaft 804. The worm gear 803 meshes with a worm wheel 802, which is fixedly mounted on a connecting shaft 7. By rotating the rotating shaft 804, the worm gear 803 is driven to rotate, which in turn drives the worm wheel 802 to rotate. The rotation of the worm wheel 802 drives the connecting shaft 7 to rotate. The transmission of the worm wheel 802 and the worm gear 803 can, on the one hand, use their self-locking properties to lock the connecting shaft 7, preventing the lifting plate 2 from still moving downward under gravity after being hoisted into place. On the other hand, the high reduction ratio between the worm wheel 802 and the worm gear 803 means that no great force is needed when rotating the rotating shaft 804.

[0024] The upper surface of the lifting plate 2 is inclined, and the end of the lifting plate 2 closest to the main frame 1 is the lowest end. The top of the lifting plate 2 is provided with an integrally formed anti-fall side plate 201 to prevent the air conditioner outdoor unit placed on the lifting plate 2 from slipping off.

[0025] The top of the main frame 1 is provided with a sliding groove 15, and a slider 16 is slidably arranged in the sliding groove 15. A sliding plate 14 is fixedly installed on the top of the slider 16. A stop plate 17 is fixedly installed at the bottom of the end of the sliding plate 14 away from the lifting plate 2. The outer diameter of the stop plate 17 is larger than the inner diameter of the sliding groove 15. When moving the air conditioner outdoor unit from inside the building to the lifting plate 2, the air conditioner outdoor unit can be placed on the sliding plate 14 indoors, and then the sliding plate 14 can be pushed to slide until one end of the sliding plate 14 moves above the lifting plate 2. Then the air conditioner outdoor unit can be pushed indoors to push the air conditioner outdoor unit onto the lifting plate 2. There is no need for workers to manually flip the air conditioner outdoor unit from inside to outside the building.

[0026] A handle 11 and a rectangular locking post 12 are fixedly sleeved on one end of the rotating shaft 804 that extends outside the fixed housing 801. A handle 13 is movably sleeved on the rectangular locking post 12. The outer wall of the handle 11 is provided with anti-slip protrusions. Both the handle 11 and the handle 13 are used to rotate the rotating shaft 804. That is, the operator can choose to rotate the handle 11 or the handle 13 according to their usage habits. The handle 13 is sleeved on the rectangular locking post 12. When the handle 13 is not in use, it can be removed from the rectangular locking post 12.

[0027] A reinforcing plate 9 is fixedly installed on the main frame 1. An elastic rubber pad 10 is fixedly laid on the outer wall of the side of the reinforcing plate 9 facing the wall it is erected on. The reinforcing plate 9 is used to increase the strength of the main frame 1 itself, and the elastic rubber pad 10 is used to prevent the main frame 1 from colliding with the building, thereby preventing damage to the building surface and the main frame 1.

[0028] Working principle: In use, the main frame 1 is erected on the interior or exterior walls or windows of the building. Then, the rotating shaft 804 is rotated to drive the worm gear 803 to rotate, which in turn drives the worm wheel 802 to rotate. The rotation of the worm wheel 802 drives the connecting shaft 7 to rotate, which in turn drives the winding wheel 4 to rotate, winding up the hoisting rope. This causes the hoisting rope to lift the lifting plate 2 to its highest point, placing the outdoor unit of the air conditioner on the sliding plate 14. Pushing the sliding plate 14 moves one end of it above the lifting plate 2. Then, the outdoor unit of the air conditioner is pushed from inside the building onto the lifting plate 2. Pulling up the sliding plate 14 removes it from the main frame 1. Then, the rotating shaft 804 is rotated in the opposite direction to cause the winding wheel 4 to rotate in the opposite direction, releasing the hoisting rope. Under the action of gravity, the lifting plate 2 descends until it reaches the installation height. After the worker climbs over the building, they stand on the lifting plate 2 to install the air conditioner.

[0029] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
