For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0025] like Figures 1-3 The illustrated air conditioner installation hoisting tool includes a bracket 1, which consists of a support plate 11, a support rod 12, and a crossbeam 13. The support plate is placed horizontally on the ground during use, while the support rod is connected to one end of the support plate and remains vertical. The crossbeam is connected to the upper end of the support rod and also extends horizontally during use. When hoisting the air conditioner, the bracket is placed in a Z-shape on the ground. Several counterweight plates 4 are placed on the end of the support plate furthest from the support rod to prevent the bracket from becoming unbalanced and tipping over during air conditioner hoisting.

[0026] A winding device 2 is also fixedly installed on the side of the support rod. This winding device consists of a motor reducer and a winding wheel mounted on the output shaft of the motor reducer. The motor reducer can be powered to achieve automatic winding, or it can be manually wound using a handle connected to the input shaft.

[0027] A traction assembly 3 is wound on the take-up reel of the winding device. This traction assembly consists of a traction rope and a restraint strap connected to the free end of the traction rope. It should be noted that, as... Figure 1 As shown, the traction rope is installed through the protruding end of the crossbeam so that the outdoor air conditioner unit, which is secured by the restraint strap, can be suspended by the crossbeam extending outdoors.

[0028] As a further improvement to the above embodiment, three first pin holes 121 arranged in a right-angled fan shape are provided at the end where the support rod 12 connects to the support plate 11. Correspondingly, two second pin holes 11 are provided at the end where the support plate connects to the support rod. When the support plate and the support rod are arranged perpendicularly or parallelly, the two second pin holes are aligned with two of the three first pin holes. Then, the support rod and the support plate can be fixedly connected by inserting two first pins 14. In addition, three third pin holes 122 arranged in a fan shape and two fourth pin holes 131 are provided at the end where the support rod connects to the crossbeam. It should be noted that the third pin holes and the fourth pin holes are adapted to ensure that the two fourth pin holes are aligned with two of the three third pin holes when the crossbeam is perpendicular or parallel to the support rod. Then, the support rod and the crossbeam can be fixed by inserting two second pins 15 into the aligned third pin holes and fourth pin holes.

[0029] Additionally, it should be noted that when the outdoor unit of the air conditioner is suspended outdoors, it is prone to swaying. To improve the stability during the installation of the outdoor unit, at least one set of support spokes 16 is provided on the bottom surface of the support plate 11. Each set of support spokes consists of two spokes, symmetrically arranged on both sides of the center line of the support plate's length, extending outwards to prevent the bracket 1 from tipping over when the air conditioner sways. Furthermore, in this embodiment, a groove is also provided on the bottom surface of the support plate. When this structure is not used for air conditioner installation, the support spokes 16 can be rotated and stored within it, improving ease of transport.

[0030] Furthermore, the counterweight plate 4 in this design is detachable to improve ease of handling and storage. Specifically, a fifth pin hole 112 is provided on the end of the support plate 11 away from the support rod. Simultaneously, a third pin 42 is coaxially provided on one side of the counterweight plate, which can be inserted into the fifth pin hole 41. When the counterweight plates are stacked, the lower third pin 42 is inserted into the fifth pin hole 112 to ensure the stability of the counterweight plates stacked on the support plate. In addition, a sixth pin hole 41 is coaxially provided on the back of the counterweight plate where the third pin is located. When the counterweight plates are stacked, the third pin is inserted into the sixth pin hole to improve the stability of the connection between the counterweight plates.

[0031] It should be noted that the counterweight plate is quite heavy, which makes it inconvenient for workers to move and increases their workload. To facilitate handling, the counterweight plate 4 is a hollow, water-filled structure. Water is added to the counterweight plate to increase its weight when in use, and the water is drained when not in use, making it easier to move.

[0032] In addition, to facilitate the overall transport of this device, a hanging rod 123 is provided on the support rod 12, which is adapted to the sixth pin hole 41 on the counterweight plate 4. When the counterweight plate is removed, the hanging rod is inserted into the sixth pin hole so that the counterweight plate can be hung on the support rod. It should be noted that, in order to prevent the counterweight plate from falling during transport, the upright support plate can block the other side of the counterweight plate.

[0033] Working principle: When air conditioner installation is required, workers unfold the folded bracket into a Z-shape and insert pins into the corresponding holes to ensure stability. Next, the counterweight plate is removed from the hanging rod and water is added to it. Then, the counterweight plate is stacked on the support plate, and the third pin of the bottom counterweight plate is inserted into the fifth pin hole. After these preparations are completed, workers can suspend the air conditioner outdoor unit on the traction assembly and slowly lower it outdoors to complete the installation.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
