[0001] This utility model relates to the field of air conditioning installation technology, specifically to a central air conditioning installation bracket. Background Technology

[0002] Central air conditioning is a multi-split system consisting of one outdoor unit and multiple indoor units. It can provide cooling or heating to multiple rooms simultaneously. Cool or hot air is delivered to each room through ducts and vents. The indoor units of a central air conditioning system are usually hidden in the ceiling, and the air conditioner needs to be supported during installation.

[0003] Traditional mounting brackets are very simple, merely fixing the indoor unit in a basic way. They are mostly fixed and cannot be adjusted according to the model of the central air conditioning unit, resulting in poor applicability. Furthermore, existing central air conditioning indoor unit fixing devices are simply fixed directly with fasteners and cannot be adjusted according to the size of the central air conditioning indoor unit, leading to low universality and efficiency. Utility Model Content

[0004] To solve the above-mentioned technical problems, a central air conditioning installation bracket is provided. This technical solution addresses the issues raised in the background art regarding the very simple traditional installation brackets, which merely fix the indoor unit and are mostly fixed, unable to be adjusted according to the model of the central air conditioning unit, resulting in poor applicability; and the existing central air conditioning indoor unit fixing devices are simply fixed directly by fasteners, unable to be adjusted according to the size of the central air conditioning indoor unit, resulting in low universality and efficiency.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] The mounting mechanism includes a first lead screw, which is rotatably mounted inside the machine frame. Two sets of first sliders are threadedly connected to the outer surface of the first lead screw, and both sets of first sliders are slidably mounted in movable grooves opened on the front outer surface of the machine frame. Mounting brackets are rotatably mounted on the front side of both sets of first sliders. Guide bars are provided at the bottom ends of both sets of mounting brackets. Second sliders are slidably mounted inside both sets of guide bars. The bottom ends of both sets of second sliders are rotatably connected to the front end of a third slider through connectors. Both sets of third sliders are slidably mounted in sliding grooves opened on the front outer surface of the machine frame.

[0008] Preferably, the two sets of threads on the outer surface of the first lead screw have opposite directions of rotation, and the output end of the first motor is fixedly installed at one end of the first lead screw.

[0009] Preferably, the adjusting mechanism includes a fixed plate, a second lead screw is rotatably mounted on the inner side of the fixed plate, a guide rod is also provided on the inner side of the fixed plate, and two sets of first movable blocks and second movable blocks are threadedly connected to the outer surface of the second lead screw. The two sets of first movable blocks and second movable blocks are also slidably mounted on the outer surface of the guide rod.

[0023] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0024] Reference Figure 1-4 As shown, a central air conditioning mounting bracket includes a frame 1, an installation mechanism 2 inside the frame 1, and an adjustment mechanism 3 at the top of the frame 1. The installation mechanism 2 includes a first lead screw 201, which is rotatably mounted inside the frame 1. Two sets of threads on the outer surface of the first lead screw 201 have opposite directions of rotation, and the output end of a first motor 202 is fixedly mounted at one end of the first lead screw 201. Two sets of first sliders 203 are threadedly connected to the outer surface of the first lead screw 201, and both sets of first sliders 203 are slidably mounted on the frame 1. Inside the movable groove 101 on the front outer surface, mounting brackets 204 are rotatably mounted on the front side of the two sets of first sliders 203. The top of the mounting brackets 204 is provided with several sets of first mounting holes 205. Guide bars 206 are provided at the bottom of the two sets of mounting brackets 204. Second sliders 207 are slidably mounted inside the two sets of guide bars 206. The bottom of the two sets of second sliders 207 are rotatably connected to the front end of the third slider 209 through connectors 208. The two sets of third sliders 209 are slidably mounted in the sliding groove 102 on the front outer surface of the frame 1.

[0025] In this design, the first lead screw 201, with its two sets of reverse threads, allows the two sets of first sliders 203 to move towards or away from each other during rotation. Combined with the drive of the first motor 202, this enables automatic adjustment of the spacing between the mounting brackets 204, facilitating quick adaptation and installation according to the dimensions of the central air conditioner, thus improving installation efficiency and flexibility. Furthermore, the combination of guide strips 206 with the second slider 207 and the third slider 209 ensures stable vertical support for the mounting brackets 204 through the guiding action of the guide strips 206 and the connecting parts 208 between the sliders, further enhancing the stability of the installation.

[0026] Reference Figure 1-4 As shown, the adjustment mechanism 3 includes a fixed plate 301. A second lead screw 302 is rotatably mounted on the inner side of the fixed plate 301. Four sets of threads on the outer surface of the second lead screw 302 are all turned in opposite directions. The output end of the second motor 304 is fixedly mounted on one end of the second lead screw 302. A guide rod 303 is also provided on the inner side of the fixed plate 301. Two sets of first movable blocks 305 and second movable blocks 306 are threadedly connected to the outer surface of the second lead screw 302. The two sets of first movable blocks 305 and second movable blocks 306 are also slidably mounted on the outer surface of the guide rod 303. The top ends of the two sets of first movable blocks 305 and second movable blocks 306 are movably connected to the bottom end of the mounting plate 309 through two sets of first connecting rods 307 and second connecting rods 308. Several sets of second mounting holes 310 are provided on the outer surface of the top end of the mounting plate 309.

[0027] In this solution, firstly, the four sets of reverse threads on the second lead screw 302 enable the two sets of first movable blocks 305 and two sets of second movable blocks 306 to adjust their displacement when the second lead screw 302 rotates. Combined with the drive of the second motor 304, this simplifies the adjustment process and improves the synchronization and accuracy of the adjustment. Secondly, the guide rod 303 prevents the two sets of first movable blocks 305 and two sets of second movable blocks 306 from skewing or shaking due to relying solely on threaded connections, ensuring the smoothness and reliability of the entire adjustment process. The movable connection between the first connecting rod 307 and the second connecting rod 308 and the mounting plate 309 allows for flexible adjustment of the height of the mounting plate 309 and corresponding changes in the position of the second mounting hole 310, thus meeting the needs of different installation heights and spatial layouts and enhancing the adaptability and flexibility of central air conditioning installation.

[0028] The working principle of this utility model is as follows: First, the mounting plate 309 is fixedly installed on the ceiling through the second mounting hole 310. By starting the second motor 304, its output end drives the second lead screw 302 to rotate. The four sets of reverse threads on the outer surface of the second lead screw 302 allow the two sets of first movable blocks 305 and two sets of second movable blocks 306 to move up and down when the second lead screw 302 rotates. Since the threads rotate in opposite directions, the four sets of movable blocks can adjust their positions synchronously and smoothly. The guide rod 303 ensures the stability of the first movable blocks 305 and second movable blocks 306 during movement, preventing skewing or shaking caused by relying solely on threaded connections. The sliding connection between the guide rod 303 and the movable blocks provides additional support and guidance. As the first movable blocks 305 and second movable blocks 306 move, the first connecting rod 307 and second connecting rod 308 are connected to the mounting plate 309, which drives the frame 1 and the mounting mechanism. 2. Height adjustment is performed to fix the central air conditioner at different heights. When the central air conditioner needs to be installed, the first motor 202 is started. The output end of the first motor 202 drives the first lead screw 201 to rotate. Since the two sets of threads on the outer surface of the first lead screw 201 have opposite directions of rotation, when the first lead screw 201 rotates, the two sets of first sliders 203 will move along the thread direction of the first lead screw 201. Since the threads have opposite directions of rotation, the two sets of first sliders 203 will move towards or away from each other, thereby adjusting the distance between the two sets of mounting brackets 204. As the two sets of first sliders 203 move, the mounting brackets 204 also move until they reach a position suitable for the size of the central air conditioner. The top of the mounting bracket 204 has several sets of first mounting holes 205 for fixing the central air conditioner. In order to ensure the stable support of the mounting bracket 204 in the vertical direction, the guide bar 206 cooperates with the second slider 207 and the third slider 209, which enhances the stability of the mounting bracket 204.

[0029] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of this utility model.
