Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of ceiling fans, and in particular to a height-adjustable large ceiling fan suspension device. BACKGROUND

[0002] Currently, industrial ceiling fans are usually installed in a specific position using a fixed suspension device, and the height and angle cannot be adjusted as needed, which may cause inconvenience or poor results in some cases. The existing technology usually uses a fixed suspension device, which cannot flexibly adjust the height and angle of the ceiling fan, limiting the ventilation effect and application range of the ceiling fan. Therefore, the height and angle of the existing suspension device are not adjustable, resulting in uneven wind distribution in spaces of different heights, and also causing inconvenience in cleaning and maintenance.

[0003] In the published patent with authorization announcement number CN214577809U, an angle-adjustable suspension device for a large ceiling fan is disclosed, which includes a ceiling fan body and a mounting plate. The two ends of the bottom of the mounting plate are fixedly installed with first hangers, and the inside of the first hangers is provided with first positioning holes. The top of the second hanger is sleeved with a first positioning bolt, the bottom of the two second hangers is sleeved with a transmission shaft, and the opposite sides of the two transmission shafts are fixedly installed with receiving plates. The inside of the adjusting plate is provided with an adjusting hole, the bottom of the second hanger is provided with a second positioning hole, and the inside of the second positioning hole is sleeved with a second positioning bolt. By setting the adjusting plate, the adjusting hole, the second positioning hole, the second fixing bolt, and the transmission shaft, the angle of the ceiling fan body can be adjusted by rotating the adjusting plate. The second fixing bolt is used to fix the adjusting plate and the second hanger, which is convenient and simple. The device has the function of adjusting the height and angle of the ceiling fan body, and can better meet the needs of users.

[0004] The angle-adjustable suspension device for a large ceiling fan in the above-mentioned patent solves the problem of height adjustment, but when the height of the ceiling fan body needs to be adjusted, the two first positioning bolts are removed, and the second hanger is in a movable state. By pulling up and down the two second hangers, the height of the ceiling fan body can be adjusted. Then, the first positioning bolt is inserted into the inside of the first positioning hole in the opposite position and fixed with a nut to fix the first hanger and the second hanger. Due to the shape and design of the first hanger and the second hanger, when the second hanger is in a movable state, the first hanger is open, and the second hanger cannot always maintain balance in the first hanger during adjustment. The second hanger may deviate from the first hanger, and the positioning holes on the first hanger and the second hanger cannot be aligned, so it is time-consuming and laborious to adjust the height, which is not convenient for people to operate, and the use effect and efficiency are greatly affected.

[0005] Therefore, the present application provides a height-adjustable large ceiling fan suspension device. CONTENT OF THE UTILITY MODEL

[0006] The adjustable height large ceiling fan hanging device is provided to solve the problems in the background art. When the height of the ceiling fan body needs to be adjusted, the positioning plate is counterclockwise rotated, so that the threaded rod is separated from the threaded hole. At this time, the sleeve rod is in a movable state in the sleeve. When the height is adjusted by controlling the sleeve rod to move up and down in the sleeve, the gear on the sleeve rod rotates in the movable groove through the connecting rod. When the gear rotates, it is engaged with the tooth groove in the sleeve. Therefore, the position of the sleeve rod can be kept balanced when the height is adjusted in the sleeve, so that the stability of the ceiling fan body during height adjustment is ensured, the adjustment time is saved, the efficiency and effect of the ceiling fan body adjustment are improved, and the practicability of the device is greatly improved.

[0017] As a preferred embodiment, the end of each of the two threaded rods away from the threaded hole is fixedly connected with a positioning plate outside the sleeve through a slot hole, and the side of each of the two positioning plates close to the threaded rod is in contact with the outside of the sleeve.

[0018] By setting the positioning plate, the side of the positioning plate close to the threaded rod is in close contact with the outside of the sleeve, and through the mutual force, the sleeve rod is stably connected inside the sleeve, thereby improving the practicality of the device.

[0019] As a preferred embodiment, the bottom end of each of the two sleeve rods is fixedly connected with a second mounting mechanism, which comprises a fixed plate, a groove, an installation rod, a disc and a fixed bolt. The fixed plate is fixedly connected at the bottom end of the two sleeve rods, and the inside of the fixed plate is provided with a groove.

[0020] By setting the second mounting mechanism, the structure design is simple, easy to disassemble, and quick to install, thereby improving the practicality of the device.

[0021] As a preferred embodiment, the inside of the groove is provided with an installation rod, the bottom end of the installation rod is fixedly connected with the top of the ceiling fan body, the top end of the installation rod is fixedly connected with a disc, the inside of the disc is threadedly connected with a plurality of fixed bolts, and the bottom end of each fixed bolt extends into the inside of the fixed plate.

[0022] By setting the second mounting mechanism, when it is necessary to disassemble the ceiling fan body and clean the fan blades on the ceiling fan body, the fixed bolts on the disc can be disassembled by tools, and at this time the installation rod is in a movable state, and the installation rod can be taken off from the groove on the fixed plate, thereby improving the practicality of the device.

[0023] The beneficial effects of the present application are:

[0024] 1. The height-adjustable large ceiling fan hanging device is provided with an adjusting mechanism, a limiting mechanism and a positioning mechanism. When the height of the ceiling fan body needs to be adjusted, the positioning plate is counterclockwise rotated, so that the threaded rod is separated from the threaded hole. At this time, the sleeve rod is in a movable state in the sleeve. When the height is adjusted by controlling the sleeve rod to move up and down in the sleeve, the gear on the sleeve rod rotates in the movable groove through the connecting rod. When the gear rotates, it is engaged with the tooth groove inside the sleeve. Therefore, when the height of the sleeve rod in the sleeve is adjusted, the position is always balanced and there is no problem of tilting, thereby ensuring the stability of the ceiling fan body during height adjustment, saving adjustment time, improving the efficiency and effect of the ceiling fan body adjustment, and greatly improving the practicality of the device.

[0025] 2. The height-adjustable large ceiling fan hanging device is provided with a second mounting mechanism. When the ceiling fan body needs to be disassembled and the fan blades on the ceiling fan body need to be cleaned, the fixing bolt on the disc can be disassembled by a tool. At this time, the mounting rod is in a movable state, and the mounting rod can be removed from the groove on the fixed plate. The structure design is simple, convenient to disassemble, fast to install, and greatly improves the practicality of the device. BRIEF DESCRIPTION OF DRAWINGS
