[0002] Industrial fans, as ventilation equipment, are commonly used in various factories. Currently, industrial fans are fixedly suspended from factory ceilings, primarily for cooling the area. However, installation requires numerous bolts to secure the fans, making removal cumbersome and necessitating the removal of many bolts for maintenance. Therefore, there is an urgent need to develop an industrial fan with a simple structure, easy operation, and quick disassembly and maintenance, featuring a quick-release suspension rod, to overcome the shortcomings of current applications and meet current needs. Utility Model Content

[0003] The purpose of this invention is to provide an industrial fan with a quick-release suspension rod structure to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] An industrial fan with a quick-release suspension rod structure includes a connecting base, a fan suspension rod, a fan blade assembly, a disc, a cylinder, a cylinder mounting block, a connecting rod, a grooved ring, and a fan motor. The fan suspension rod is fixed to the lower side of the connecting base by a bolt assembly. The fan motor is fixed to the lower side of the disc by a bolt assembly. The output shaft of the fan motor is fixedly connected to the fan blade assembly. The grooved ring is located on the upper side of the disc. The cylinder mounting block is fixedly mounted on the disc. The tail of the cylinder is hinged to the cylinder mounting block. The piston rod of the cylinder is hinged to the connecting rod. The connecting rod is fixed to the disc by a bolt assembly. Three guide rails are fixed on the disc. A slider is slidably mounted on each guide rail. A locking block is fixed on each slider. The lower end of the fan suspension rod is provided with a locking groove for the locking block to be inserted. A guide post penetrating the grooved ring is fixed on each locking block. Three guide post grooves for the sliding of the guide post are evenly distributed on the grooved ring.

[0006] Preferably, a positioning hole for inserting a fan rod is provided at the center of the disc.

[0007] Preferably, three limiting posts that penetrate the grooved ring are evenly distributed and fixed on the upper side of the disk, and three limiting post grooves for sliding of the limiting posts are evenly distributed on the grooved ring.

[0008] Preferably, the three locking blocks are evenly distributed in a circle with the central axis of the disk as the reference.

[0009] Preferably, the locking groove is an annular groove.

[0010] Preferably, the locking slot is three fan-shaped grooves evenly distributed around the fan rod.

[0011] The beneficial effects of this utility model are as follows: During installation, the connecting seat of this industrial fan with a quick-release suspension rod is fixed to the factory ceiling. In the locked state, the piston rod of the cylinder is in a retracted state, and the three locking blocks are inserted into the locking slots to form a three-point limit, thus ensuring a stable connection between the locking blocks and the disc and the fan suspension rod. During disassembly, pushing the piston rod outward causes the connecting rod and the grooved ring to rotate clockwise. The guide post groove on the grooved ring causes the guide post to slide within the guide post groove, which in turn causes the locking blocks and the slider to slide outward along the guide rail, allowing the locking blocks to be pulled out of the locking slots. Then, the grooved ring, disc, fan motor, and fan blade assembly can be removed from the fan suspension rod for maintenance. In summary, this utility model has a simple structure, is easy to operate, and facilitates quick disassembly and maintenance. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0021] Specific implementation examples are given below.

[0022] Example 1

[0023] See Figures 1-4 In this embodiment of the present invention, an industrial fan with a quick-release suspension rod structure includes a connecting seat 1, a fan suspension rod 2, a fan blade assembly 3, a disc 4, a cylinder 5, a cylinder mounting block 6, a connecting rod 7, a grooved ring 8, and a fan motor 14. The connecting seat 1 is fixed to the ceiling of the factory by a bolt assembly. The fan suspension rod 2 is fixed to the lower side of the connecting seat 1 by a bolt assembly. A positioning hole for inserting the fan suspension rod 2 is provided in the middle of the disc 4. The fan motor 14 is fixed to the lower side of the disc 4 by a bolt assembly. The output shaft of the fan motor 14 is fixedly connected to the fan blade assembly 3. The grooved ring 8 is located on the upper side of the disc 4. The cylinder mounting block 6 is fixedly mounted on the disc 4. The tail of the cylinder 5 is connected to the cylinder mounting block 6. The piston rod of cylinder 5 is hinged to connecting rod 7. Connecting rod 7 is fixed to disc 4 by bolt assembly. Three guide rails 12 are fixed on disc 4. A slider 11 is slidably installed on each guide rail 12. A locking block 9 is fixed on each slider 11. The three locking blocks 9 are evenly distributed in a circle with the central axis of disc 4 as the reference. The lower end of fan rod 2 is provided with locking slot 201 for the insertion of locking blocks 9. A guide post 10 that passes through a grooved ring 8 is fixed on each locking block 9. Three guide post slots 801 for sliding of guide post 10 are evenly distributed on the grooved ring 8. The three locking blocks 9 are inserted into the locking slot 201 to form a three-point limit, so that the locking blocks 9, disc 4 and fan rod 2 are stably connected together.

[0024] When in use, cylinder 5 is supplied with compressed air from an external source, and fan motor 14 is powered by an external power source.

[0025] Three limiting posts 13 that pass through the grooved ring 8 are evenly distributed and fixed on the upper side of the disk 4. Three limiting post grooves 802 for sliding of the limiting posts 13 are evenly distributed on the grooved ring 8.

[0026] Example 2

[0027] See Figure 5 The locking slot 201 is a circular groove, which makes it easier to insert the three locking blocks 9.

[0028] Example 3

[0029] See Figure 6 The locking slot 201 consists of three fan-shaped grooves evenly distributed around the fan rod 2. The design of the fan-shaped grooves ensures that the locking block 9 will be tightly locked after insertion and will not slide relative to the fan rod 2 in the circumferential direction.

[0030] Working principle: This industrial fan with a quick-release suspension rod structure is installed by fixing the connecting seat 1 to the factory ceiling. In the locked state, the piston rod of the cylinder 5 is in the retracted state, and the three locking blocks 9 are inserted into the locking slot 201 to form a three-point limit, thereby making the locking blocks 9 and the disc 4 stably connected to the fan suspension rod 2. When disassembling, the piston rod of the cylinder 5 is pushed outward, which drives the connecting rod 7 and the grooved ring 8 to rotate clockwise. The guide post groove 801 on the grooved ring 8 drives the guide post 10 to slide in the guide post groove 801. The guide post 10 drives the locking block 9 and the slider 11 to slide outward along the guide rail 12, thereby making the locking block 9 pull out from the locking slot 201. Then, the grooved ring 8, the disc 4, the fan motor 14, and the fan blade assembly 3 can be removed from the fan suspension rod 2 for maintenance.
