Description

Technical Field

[0001] This utility model relates to the field of industrial ventilation equipment technology, and in particular to a micro-adjustment structure for rotary blade industrial ceiling fans. Background Technology

[0002] Rotary blade industrial ceiling fans are common ventilation and cooling equipment in large factories and logistics warehouses. They are suspended and installed on the steel beams or ceilings of buildings to achieve wide-range air circulation and coverage.

[0003] However, existing industrial ceiling fans mostly use traditional flanges and multiple bolts for rigid fixing in their installation structure. This installation method not only requires operators to perform tedious thread tightening work with complex tools such as wrenches at height for extended periods during initial assembly or subsequent maintenance and disassembly, resulting in low installation efficiency and high labor intensity, but more importantly, due to the limitations of this traditional rigid connection structure and the high-altitude installation environment, the air delivery angle of existing industrial ceiling fans remains constant after fixing. It cannot be flexibly changed according to the layout of equipment in the workshop or the air delivery needs of different seasons. If the air delivery angle needs to be adjusted, it requires manual adjustment by climbing to a height using large auxiliary equipment such as a lift. This is not only time-consuming and labor-intensive, posing significant safety hazards for working at height, but also makes it difficult to ensure the accuracy of angle control by manual adjustment. Under the continuous vibration generated by the long-term operation of industrial ceiling fans, the simple manual adjustment structure is also prone to loosening and displacement, resulting in unstable air delivery effect.

[0004] Therefore, this utility model proposes a micro-adjustment structure for the angle of a rotary blade industrial ceiling fan to address the shortcomings of existing technologies. Utility Model Content

[0005] In view of the problems existing in the technology of rotary blade industrial ceiling fans, such as cumbersome and time-consuming installation and disassembly processes, reliance on complex tools and high-altitude operation difficulties, as well as the difficulty in accurately adjusting the air delivery angle and poor adjustment stability after installation and fixing, this utility model aims to provide a rotary blade industrial ceiling fan angle fine-tuning structure with improved structure that can effectively solve the above problems.

[0006] This utility model provides a micro-adjustment structure for a rotary blade industrial ceiling fan, including a hollow block, an adjustment mechanism disposed inside the hollow block, and a quick-release mechanism disposed on the top of the hollow block. The adjustment mechanism includes a servo motor fixedly connected to the inner wall of the hollow block, a worm gear fixedly connected to the output end of the servo motor, a support plate fixedly connected to the top of the inner wall of the hollow block, a fixed rod rotatably connected to the middle of the inner wall of the support plate, a semi-circular worm wheel meshing with the worm gear fixedly connected to the middle of the outer wall of the fixed rod, and a C-shaped plate fixedly connected to the outer wall of the fixed rod. The bottom of the C-shaped piece is fixedly connected to a support rod, and the bottom end of the support rod is fixedly connected to a fan. The quick-release mechanism includes an L-shaped plate fixedly connected to the left and right sides of the top of the hollow block, and a circular plate fixedly connected to the adjacent side of the outer wall of the L-shaped plate. The quick-release mechanism also includes a hollow circular block placed on the top of the circular plate. The left and right sides of the top of the hollow circular block are fixedly connected to T-shaped fixing plates. The inner wall of the top of the hollow circular block is threaded with a threaded short post. The bottom end of the threaded short post is fixedly connected to a fixing short post. The outer wall of the fixing short post is fixedly connected to a locking plate.

[0007] Preferably, the bottom end of the circular plate is provided with a cross-shaped protrusion and groove, and the locking plate is configured to be able to be embedded in the cross-shaped protrusion and groove and to cooperate with the cross-shaped protrusion and groove to achieve initial locking and positioning between the components.

[0008] Preferably, the cross-shaped convex-recessed groove structure includes a raised area and a recessed area, and the locking plate is configured to form a limiting lock when rotated to the raised area, thereby using the physical obstruction of the mechanical structure to prevent the connection from loosening.

[0009] Preferably, the bottom of the T-shaped fixing plate is threaded with bolts at equal intervals. The bolts are used to fix the T-shaped fixing plate to the mounting surface, thereby providing a stable suspension foundation for the overall device.

[0010] Preferably, the threaded short column and the hollow circular block form a threaded transmission structure. The threaded short column is configured to drive the fixed short column and the locking plate to move up and down synchronously by rotation, thereby realizing the axial displacement control of the locking component by using the threaded lifting principle.

[0011] Preferably, the L-shaped plate is set as an alignment mounting reference surface, and the circular plate provides support and positioning for the hollow circular block, assisting operators in quickly finding the correct position and sharing the weight during installation.

[0012] Preferably, the semi-circular worm gear is configured to drive the fixed rod to rotate at a corresponding angle through the rotation of the worm, thereby utilizing the worm gear transmission characteristics to achieve speed reduction, torque increase, and angle adjustment.

[0013] Preferably, the C-shaped piece is configured to deflect together with the fixed rod and cause the support rod to change angle, thereby converting the internal rotational motion into the angle deflection of the external fan.

[0014] This utility model has the following beneficial effects: 1. This utility model solves the problem of existing industrial ceiling fans having difficult manual adjustment of the air delivery angle due to their high installation position and the low precision and poor stability of traditional adjustment methods. It achieves the effect of electric precise micro-adjustment of the air delivery angle. Furthermore, the self-locking characteristic of the worm gear mechanism ensures that the fan angle does not deviate under long-term vibration environment, thus meeting the air delivery needs of various industrial scenarios.

[0015] 2. This utility model, by setting a quick-release mechanism with a threaded transmission component and a cross-shaped convex and concave groove on the top of the hollow block, uses the rotation of the threaded short column to drive the locking plate to move axially, and uses the raised area of ​​the cross-shaped convex and concave groove to achieve rotational locking and positioning. This solves the problems of cumbersome operation, reliance on a large number of bolts for fixing, and time-consuming and labor-intensive operation of existing ceiling fans during installation, maintenance and disassembly. It achieves the effect of quickly mounting or separating the ceiling fan body from the mounting base without the need for complicated tools, significantly reducing the difficulty and labor intensity of high-altitude operations and improving the maintenance efficiency of the equipment.

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0019] Example: Please refer to Figures 1 to 6 This utility model provides a micro-adjustment structure for a rotary blade industrial ceiling fan, which aims to solve the structural defects of existing industrial ceiling fans, such as cumbersome operation during installation and disassembly and difficulty in accurately adjusting the air delivery angle after installation.

[0020] Please refer to Figure 1 and Figure 2 The rotary blade industrial ceiling fan angle adjustment structure includes a hollow block 1, an adjustment mechanism 2 located inside the hollow block 1 for adjusting the air delivery angle of the fan 208, and a quick-release mechanism 3 located on the top of the hollow block 1 for quick assembly and disassembly. The hollow block 1 serves as the mounting base and protective shell of the overall structure, providing installation space and protection for the components inside the hollow block 1. The adjustment mechanism 2 is located in the inner cavity of the hollow block 1 and extends to the outside of the hollow block 1 to connect to the fan 208. The quick-release mechanism 3 is located on the top of the hollow block 1 to connect to the external mounting surface. Through the cooperation of the adjustment mechanism 2 and the quick-release mechanism 3, the ceiling fan can be conveniently installed and its angle can be flexibly adjusted.

[0021] The adjustment mechanism 2 includes a servo motor 201 fixedly connected to one side of the inner wall of the hollow block 1. The servo motor 201 serves as a power source to provide rotational driving force. A worm gear 202 is fixedly connected to the output end of the servo motor 201, and the worm gear 202 rotates synchronously with the servo motor 201. A support plate 204 is fixedly connected to the top of the inner wall of the hollow block 1. The support plate 204 has an inverted U-shaped structure to provide a stable support point. A fixed rod 205 is rotatably connected to the middle of the inner wall of the support plate 204. The two ends of the fixed rod 205 are rotatably connected to the two opposite side walls of the support plate 204 through bearing assemblies. A semi-circular worm wheel 203, which meshes with the worm gear 202, is fixedly connected to the middle of the outer wall of the fixed rod 205. Driven by the worm gear 202, the circular worm wheel 203 drives the fixed rod 205 to rotate around its own axis. A C-shaped piece 206 is fixedly connected to one end of the fixed rod 205 that extends to the outside of the hollow block 1. A support rod 207 is fixedly connected to the bottom of the C-shaped piece 206. An opening for the support rod 207 to swing is provided at the bottom of the hollow block 1. A fan 208 is fixedly connected to the bottom of the support rod 207. The adjustment mechanism 2 uses the servo motor 201 to drive the worm gear 202 to rotate. Through the meshing transmission between the worm gear 202 and the semi-circular worm wheel 203, the fixed rod 205 is driven to rotate, which in turn causes the C-shaped piece 206 to drive the support rod 207 and the fan 208 to deflect, thereby achieving precise adjustment of the air delivery angle.

[0022] Regarding the overall structure of the quick-release mechanism 3, the quick-release mechanism 3 includes an L-shaped plate 301 fixedly connected to the left and right sides of the top of the hollow block 1. The L-shaped plate 301 is used to provide lateral support and positioning reference. A circular plate 307 is fixedly connected to the adjacent side of the outer wall of the L-shaped plate 301. The circular plate 307 is a key component for load-bearing and locking. The quick-release mechanism 3 also includes a hollow circular block 306 placed on top of the circular plate 307. T-shaped fixing plates 305 are fixedly connected to the left and right sides of the top of the hollow circular block 306. Plate 305 is used for fixed connection with external mounting surface. The inner wall of the top of hollow round block 306 is threaded with a threaded short post 303. The bottom of the threaded short post 303 is fixedly connected with a fixed short post 302. The outer wall of the fixed short post 302 is fixedly connected with a locking plate 308. The locking plate 308 is located in the area below the round plate 307. The rotation of the threaded short post 303 drives the fixed short post 302 and the locking plate 308 to generate displacement, thereby realizing the locking or separation between hollow round block 306 and round plate 307.

[0023] Please refer to Figure 3 , Figure 4 and Figure 6The servo motor 201 is fixedly installed on one side of the inner wall of the hollow block 1. The output shaft of the servo motor 201 is fixedly connected to the worm gear 202 through a coupling. The worm gear 202 extends horizontally. The support plate 204 is fixedly installed at the top of the inner wall of the hollow block 1. The support plate 204 has an inverted U-shaped structure. The fixing rod 205 passes horizontally through the middle area of ​​the support plate 204. The two ends of the fixing rod 205 are rotatably installed on the two side walls of the support plate 204 through bearing assemblies. The semi-circular worm wheel 203 is fixedly sleeved on the rod body of the fixing rod 205 located inside the support plate 204. The teeth on the lower surface of the semi-circular worm wheel 203 are engaged with the threads on the surface of the worm gear 202 to ensure that the fan 208 maintains its current angle without deviation when the power is off.

[0024] One end of the fixed rod 205 extends to the outside of the hollow block 1. The C-shaped piece 206 is fixedly connected to the outer wall of the hollow block 1 by the mounting ears at both ends. A support rod 207 is vertically fixedly connected to the center of the arc-shaped plate at the bottom of the C-shaped piece 206. The bottom end of the support rod 207 is fixedly connected to the top end of the fan 208. An clearance opening is provided on the bottom surface of the hollow block 1 to allow the support rod 207 to swing. The support rod 207 passes through the clearance opening and extends to the bottom of the hollow block 1. The C-shaped piece 206 is located in the area below the hollow block 1. When the servo motor 201 drives the worm gear 202 to rotate, the worm gear 202 drives the semi-circular worm wheel 203 to rotate, which in turn drives the fixed rod 205 to rotate. The fixed rod 205 drives the C-shaped piece 206 to deflect, which ultimately causes the support rod 207 to drive the fan 208 to adjust the air delivery angle within the range allowed by the clearance opening.

[0025] As a preferred embodiment, to achieve rapid installation and disassembly of the entire ceiling fan body, the quick-release mechanism 3 adopts a multi-stage locking structure. The bottom of the T-shaped fixing plate 305 is connected with multiple bolts 304 at equal intervals. The bolts 304 are used to provide threaded locking force during the installation stage to firmly fix the T-shaped fixing plate 305 to the external mounting surface, thereby completing the initial positioning of the hollow round block 306. At the same time, the L-shaped plate 301 is used to align the mounting reference surface during installation, and the circular plate 307 provides initial support and positioning for the hollow round block 306 placed on top.

[0026] As another preferred embodiment, in order to achieve mechanical limiting and stable connection between the hollow circular block 306 and the circular plate 307, a threaded short column 303 is threadedly connected to the inner wall of the top of the hollow circular block 306. The threaded short column 303 and the hollow circular block 306 form a threaded transmission structure. A fixed short column 302 is fixedly connected to the bottom of the threaded short column 303. A locking plate 308 is fixedly connected to the outer wall of the fixed short column 302. The locking plate 308 is located in the area below the circular plate 307. By rotating the threaded short column 303, the fixed short column 302 and the locking plate 308 can be driven to move up and down axially synchronously, thereby locking and unlocking the ceiling fan body.

[0027] In another preferred embodiment, to precisely control the locking and disengaging positions of the locking plate 308, a cross-shaped groove 309 is provided at the bottom of the circular plate 307. The structure of the cross-shaped groove 309 includes a raised area and a recessed area. The shape of the locking plate 308 is adapted to the shape of the cross-shaped groove 309. When the threaded short post 303 drives the locking plate 308 to move downward and embed into the cross-shaped groove 309, the locking plate 308 continues to rotate. When the locking plate 308 rotates to the raised area of ​​the groove, the raised structure forms a limiting lock on the locking plate 308, realizing a stable connection between the hollow circular block 306 and the circular plate 307. In the reverse operation, the locking plate 308 rotates to the recessed area, releasing the raised limiting, and can then smoothly disengage from the cross-shaped groove 309.

[0028] As a preferred implementation of angle adjustment, to ensure precise control and stability of the air delivery angle, the worm gear 202 drives the semi-circular worm wheel 203 to rotate at a corresponding angle through meshing connection. The rotation of the semi-circular worm wheel 203 synchronously drives the fixed rod 205 fixedly connected to it to rotate, realizing the deceleration and self-locking function of the worm gear 202 and worm wheel. The C-shaped plate 206 is fixedly connected to the outer wall of the fixed rod 205. The C-shaped plate 206 deflects together with the fixed rod 205, thereby causing the support rod 207 fixedly connected to the bottom of the C-shaped plate 206 to change angle, and finally realizes the precise adjustment of the air delivery angle of the fan 208.

[0029] Working Principle: When the ceiling fan needs to be assembled and used, the quick-release mechanism 3 enables rapid installation. During the assembly stage, the L-shaped plates 301 fixedly connected to the top left and right sides of the hollow block 1 are aligned with the installation reference surface. The circular plates 307 fixedly connected to the adjacent side of the outer wall of the L-shaped plates 301 provide support and positioning. Then, the hollow circular block 306 is placed on top of the circular plates 307, so that the T-shaped fixing plates 305 fixedly connected to the top left and right sides of the hollow circular block 306 fit against the installation surface. Next, the multiple bolts 304 with equidistant threaded connections at the bottom of the T-shaped fixing plates 305 are tightened in sequence. The thread locking force of the bolts 304 firmly fixes the T-shaped fixing plates 305 to the installation surface, thus completing the assembly of the hollow circular block. After the initial positioning of 306, the threaded short column 303 connected to the inner wall of the top of the hollow round block 306 is rotated. With the help of the threaded transmission, the fixed short column 302 fixedly connected to the bottom of the threaded short column 303 moves downward synchronously until the locking plate 308 fixedly connected to the outer wall of the fixed short column 302 is embedded in the cross-shaped protrusion and groove 309 opened at the bottom of the round plate 307. Since the structure of the cross-shaped protrusion and groove 309 includes protruding and recessed areas, when the locking plate 308 rotates to the protruding part of the cross-shaped protrusion and groove 309, the protruding structure forms a limit lock on the locking plate 308, realizing a stable connection between the hollow round block 306 and the round plate 307, and finally completing the assembly and fixing of the ceiling fan. During the disassembly stage, simply rotate the threaded short column 303 in the opposite direction to drive the fixed short column 302 and the locking plate 308 to move upward and rotate synchronously. When the locking plate 308 rotates to the recessed area of ​​the cross-shaped groove 309, the protrusion limit is released, and the locking plate 308 smoothly disengages from the cross-shaped groove 309. Then, loosen the bolt 304 at the bottom of the T-shaped fixing plate 305 to quickly separate the hollow round block 306 from the L-shaped plate 301 and the round plate 307, completing the disassembly of the ceiling fan. The entire process requires no complicated tools, achieving efficient and convenient disassembly and assembly. After the quick-release mechanism 3 is installed and fixed, the ceiling fan's precise angle adjustment is achieved through the adjustment mechanism 2 fixedly connected to the inner wall of the hollow block 1. When it is necessary to adjust the airflow angle of the fan 208, the servo motor 201 is started. The output end of the servo motor 201 drives the worm gear 202 fixedly connected to it to rotate synchronously. Since a support plate 204 is fixedly connected to the top of the inner wall of the hollow block 1, and a fixed rod 205 is rotatably connected to the middle of the inner wall of the support plate 204, and a semi-circular worm wheel 203 fixedly connected to the middle of the outer wall of the fixed rod 205 meshes with the worm gear 202, the worm gear 203 is engaged with the worm gear 202. Therefore, the rotation of the worm gear 202 drives the semi-circular worm wheel 203 to rotate at a corresponding angle through meshing transmission. The rotation of the semi-circular worm wheel 203 synchronously drives the fixed rod 205 to rotate. The C-shaped plate 206 fixedly connected to the outer wall of the fixed rod 205 deflects together with the fixed rod 205, thereby causing the support rod 207 fixedly connected to the bottom of the C-shaped plate 206 to change angle. Finally, the fan 208 fixedly connected to the bottom of the support rod 207 follows the deflection of the support rod 207 to adjust the air delivery angle and meet the air delivery needs in different scenarios.
