[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0029] A telescopic universal positioning bracket for ceiling mounting of fan coil units, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, including

[0030] The main rod 10 has a first side rod 11 and a second side rod 12 movably arranged at both ends inside the main rod 10. A damping universal ball 13 for hinged to another set of positioning brackets is provided on one side of the first side rod 11.

[0031] The drive assembly is movably disposed within the main rod 10. The drive assembly includes a main bevel gear 15, a driven bevel gear 19, and a forward and reverse lead screw 20. The driven bevel gear 19 is fixedly disposed on the curved surface of the forward and reverse lead screw 20. Both the forward and reverse lead screw 20 and the main bevel gear 15 are rotatably disposed within the main rod 10. The main bevel gear 15 is driven above the driven bevel gear 19.

[0032] The shock-absorbing and buffering structure is movably mounted on the main rod 10, the first side rod 11, and the second side rod 12. The shock-absorbing and buffering structure includes rubber pads 24, buffer springs 25, and spring dampers 26. The rubber pads 24 are sleeved on the buffer springs 25. Two rows of rubber pads 24 and buffer springs 25 are respectively provided on the first side rod 11 and the second side rod 12. The spring dampers 26 are provided on the main rod 10.

[0033] Specifically, when using this device, a certain number of these devices need to be installed according to the side length of the ceiling structure. Multiple sets of devices are hinged together by damping universal balls 13. The damping universal balls 13 are installed on the first side rod 11 and the second side rod 12 of another set of devices. Utilizing the special properties of the damping universal balls 13, in conjunction with the drive components, the device can simultaneously have the ability to axially extend and retract at both ends and to adjust in all directions, allowing the device to adapt to various complex ceiling spaces. At the same time, after completing the axial extension and universal angle adjustment, the ceiling structure is installed between the shock-absorbing and buffering structures. The ceiling structure is securely clamped by rubber pads 24 and buffer springs 25, and the vibration transmitted from the fan to the vibration seat on the ceiling plate is slowed down by the spring damper 26. This not only reduces the wear of the device by vibration to a certain extent, but also alleviates the noise caused by vibration to a certain extent.

[0034] like Figure 1 and Figure 2 As shown, a rotating opening 16 is provided on the top surface of the main rod 10, and a rotating handle 14 is fixedly provided on the top surface of the main bevel gear 15. Both the rotating handle 14 and the main bevel gear 15 are rotatably mounted on the rotating opening 16. The rotating handle 14 is rotatably connected to the top surface of the main rod 10, and the main bevel gear 15 is rotatably mounted inside the main rod 10.

[0035] like Figure 1 and Figure 2 As shown, a bracket 18 is fixedly installed in the center of the main rod 10. The positive and negative screw rods 20 are rotatably connected inside the bracket 18. The bevel gear 19 is rotatably installed on one side of the bracket 18. The main bevel gear 15 drives and meshes with the bevel gear 19. The two ends of the positive and negative screw rods 20 are respectively threaded to the first side rod 11 and the second side rod 12.

[0036] like Figure 3 , Figure 4 and Figure 5 As shown, the main rod 10 has three sliding grooves 17 arranged in an internal array. The first side rod 11 and the second side rod 12 have the same shape and structure. Three protrusions 22 are fixedly provided on the end of the first side rod 11 and the second side rod 12 near the bracket 18. The protrusions 22 correspond to the position and shape of the sliding grooves 17. The protrusions 22 slide in the sliding grooves 17, and the sliding grooves 17 engage with the protrusions 22.

[0037] The working principle is as follows: During use, the rotation of the main bevel gear 15 is controlled by rotating the handle 14. The main bevel gear 15 meshes with the bevel gear 19, which drives the positive and negative lead screws 20 to rotate. The positive and negative lead screws 20 drive the first side rod 11 and the second side rod 12 at both ends to slide on the main rod 10. Under the sliding cooperation of the protrusion 22 and the slide groove 17, the first side rod 11 and the second side rod 12 exhibit axial expansion and contraction changes, moving inward or expanding outward at the same time.

[0038] like Figure 3 and Figure 5 As shown, a slot 23 is provided on one side of the main rod 10. The slot 23 corresponds to the shape of the slide groove 17. Multiple spring dampers 26 are arranged in an array on both the upper and lower walls of the slot 23. The spring dampers 26 on the upper and lower sides together clamp and fix the ceiling plate.

[0039] like Figure 4 and Figure 5 As shown, mounting grooves 21 are provided on the curved surfaces of the first side rod 11 and the second side rod 12, and the mounting grooves 21 correspond to the shape of the slot 23.

[0040] like Figure 4 As shown, multiple rubber pads 24 and buffer springs 25 are arranged in an array on both the upper and lower walls of the mounting groove 21. The buffer springs 25 are elastically connected to the mounting groove 21 through the rubber pads 24.

[0041] Specifically, after completing the adjustment of the first side rod 11, the second side rod 12, and the axial extension, the ceiling structure, such as the ceiling panel, can be installed in the mounting groove 21 opened on the first side rod 11 and the second side rod 12 and the slot 23 opened on the main rod 10. The two rows of spring dampers 26 arranged vertically in the slot 23 work together to elastically clamp the ceiling panel. The two rows of buffer springs 25 and rubber pads 24 arranged vertically in the mounting groove 21 also elastically clamp the ceiling panel at the same time. At this time, the composite structure of the rubber pads 24 and the buffer springs 25 can fix the ceiling panel through tension friction, and at the same time absorb the vibration of the fan operation. With the buffer and shock absorption of the spring dampers 26, the vibration of the fan operation can be further reduced, achieving the purpose of noise reduction and vibration damping.
