[0013] Compared with the prior art, the utility model has the following beneficial technical effects:

[0014] The utility model provides a positioning seat that is clamped in a limiting rotation groove formed on the inner ring surface of the stabilizing ring through the setting of the ball, and under the rolling action of the ball, the friction between the positioning seat and the stabilizing ring is conveniently reduced, thereby alleviating the resistance to the fan blade in the rotating state.

[0020] Embodiment

[0021] As Figures 1 to 3 shown, an industrial ceiling fan with multiple protections proposed by the present utility model includes a motor base 1 and a motor 2. The motor 2 is fixedly installed in the motor base 1, and the motor base 1 supports and protects the motor 2; the bottom ends of a plurality of reinforcing rods 3 are fixedly connected to the top wall of the stabilizing ring 4, and the top ends of the plurality of reinforcing rods 3 are welded to the outer surface wall of the motor base 1. The positions of the stabilizing ring 4 and the motor 2 are processed by using the reinforcing rods 3, which is beneficial to improving the position stability of the stabilizing ring 4 during use after the positions of the motor base 1 and the motor 2 are fixed.

[0022] Furthermore, a fan blade assembly 5 that is convenient for rotation is arranged in the stabilizing ring 4. The fan blade assembly 5 includes a fan blade 51, a positioning member 52, a limiting insertion block 53, a positioning socket 54, a ball 55, and a screw 56. The fan blade 51 is used for rotating and blowing air. The positioning member 52 is fixedly installed on the other side of the fan blade 51, which is convenient for subsequent fixing and positioning of the structure on the other side of the fan blade 51; the limiting insertion block 53 is fixedly installed on one side of the fan blade 51 and inserted into the recess of the positioning socket 54. The second threaded hole opened on the limiting insertion block 53 corresponds to the first threaded holes symmetrically opened on the positioning socket 54. The screw 56 is inserted into the first threaded hole and the second threaded hole to fix the position of the limiting insertion block 53, so that the structure on one side of the fan blade 51 is fixed and strengthened. Since the structures on both sides of the fan blade 51 are fixed and processed, it can rotate in a horizontal state, reduce the pressure caused by one side to the other side, and reduce the risk of bending and breaking.

[0023] Part of the structure of the positioning seat 54 is arranged in the limiting groove opened on the inner surface wall of the stabilizing ring 4, and the ball 55 is also arranged in the limiting groove. The diameter of the ball 55 is larger than the size of the notch of the limiting groove, which is beneficial to prevent the ball 55 from escaping from the limiting groove. The ball 55 is arranged in a rotating cavity opened on the positioning seat 54. The diameter of the openings at the top and bottom of the rotating cavity is smaller than the diameter of the ball 55. The ball 55 is arranged in the rotating cavity. By utilizing the openings on the top and bottom walls of the rotating cavity, part of the structure of the ball 55 is exposed to the outside, so that the ball 55 can contact the inner wall of the limiting groove, which is beneficial to reduce the influence of the stabilizing ring 4 on the ball 55 during the rotation process, and reduce the problem of increased friction resistance hindering rotation and blowing.

[0024] Furthermore, a linkage assembly 6 is provided below the motor base 1 to assist the fan blade assembly 5 in positioning and rotating. The linkage assembly 6 includes a rotating disk 61, a vertical shaft 62, a connecting seat 63, a movable disk 64, a plug 65, a bidirectional screw 66 and a guide shaft 67. The rotating disk 61 is located below the motor base 1. The top ends of the multiple vertical shafts 62 are connected to the bottom wall of the connecting seat 63, and the bottom ends are connected to the top wall of the rotating disk 61. The output end of the motor 2 is connected to a rotating shaft. The bottom end of the rotating shaft passes through an opening in the middle part of the bottom of the motor base 1 and is fixedly connected to the top wall of the connecting seat 63, so as to drive the rotating disk 61 to rotate conveniently. Two movable disks 64 are symmetrically arranged on the rotating disk In the rotating disk 61, a plurality of plugs 65 are evenly divided into two groups and symmetrically installed on the opposite wall bodies of the two movable disks 64, and are also arranged in the through holes symmetrically opened on the top wall body and the bottom wall body of the rotating disk 61, so that when the movable disk 64 contacts the top inner wall or the bottom inner wall of the rotating disk 61, the positioning member 52 inserted into the rotating disk 61 can be positioned, so that the plug 65 is inserted into the positioning hole on the arc-shaped protruding structure of the positioning member 52, so as to achieve the purpose of reinforcing the position of the fan blade 51, and facilitate the rotation of the rotating disk 61 to drive the fan blade 51 to rotate, and vice versa, the fan blade 51 in its broken state can be disassembled and replaced to avoid affecting subsequent use;

[0025] The bidirectional screw 66 is arranged in the third threaded holes formed in the two movable disks 64. Rotating holes are symmetrically formed in the top wall and the bottom wall of the rotating disk 61. The bidirectional screw 66 is arranged in the two rotating holes. At the same time, bearings are sleeved on the outer ring surfaces of the rotating disk 61 arranged in the rotating holes, which are used to assist the bidirectional screw 66 to rotate on the rotating disk 61. By rotating the bidirectional screw 66, the positions of the two movable disks 64 can be adjusted, which is convenient for disassembling and assembling the fan blades 51. The guide shaft 67 is arranged in the rotating disk 61. The top end and the bottom end of the guide shaft 67 are respectively fixedly connected to the inner wall of the top and the inner wall of the bottom of the rotating disk 61, and are arranged in the sliding holes formed in the two movable disks 64, which is used to assist the movable disks 64 to lift, so as to prevent the two movable disks 64 from rotating along with the bidirectional screw 66 during the rotation process, which affects the carrying out of the positioning or unlocking work. Due to the positioning, strengthening and supporting of the structures on both sides of the fan blade 51, the purpose of providing multiple protections for this industrial ceiling fan is achieved.
