Description

Technical Field

[0001] This utility model relates to the field of industrial fans, and in particular to a quick-release structure for an industrial fan suspension rod. Background Technology

[0002] Industrial fans are large-scale ventilation and cooling devices designed specifically for large spaces in industrial and commercial settings. Their core function is to achieve large-area airflow through a high-power, large-size fan structure, thereby achieving ventilation, environmental cooling, and improved air circulation. Unlike household fans, which are small in size and low in power, industrial fans are designed to meet the complex needs of industrial scenarios, such as "high space, high dust, high temperature, and high personnel / equipment density." They are important auxiliary devices for ensuring personnel comfort, equipment stability, and production efficiency in industrial production environments.

[0003] However, the connection between the fan blades and the boom of industrial fans often relies on 4-6 sets of bolts for fastening. Disassembly and assembly require workers to carry wrenches and other tools to operate at heights. On the one hand, the bolts are prone to rust due to long-term exposure to fan vibrations, requiring additional rust removal during disassembly. Furthermore, multiple sets of bolts need to be aligned and tightened one by one, with each disassembly and assembly taking more than 20 minutes. On the other hand, prolonged hand operation at heights can easily lead to tool drops or loss of balance due to fatigue, posing safety risks. This is especially true when frequent disassembly and assembly are required for routine maintenance, where the conflict between efficiency and safety becomes even more pronounced. Therefore, a quick-release structure for industrial fan booms is proposed to solve the above problems. Utility Model Content

[0030] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figures 1-3 The present invention provides an embodiment of a quick-release structure for an industrial fan rod, comprising a fan blade body 1, a quick-release mechanism 2 detachably mounted on the top of the fan blade body 1, the quick-release mechanism 2 being prior art, having a connecting column at its upper end and multiple sets of fan blades at its lower end.

[0032] Reference Figure 2and Figure 3 The quick-release mechanism 2 includes a fixed plate 21. An electric telescopic rod 22 is fixedly connected to the center of the upper surface of the fixed plate 21. A connecting plate 23 is fixedly connected to the telescopic end of the electric telescopic rod 22. Slide rods 24 are hinged at the four corners of the connecting plate 23. When the electric telescopic rod 22 drives the connecting plate 23 to move up and down, it will simultaneously drive the four sets of slide rods 24 to move up or down. A connecting rod a26 is hinged to the lower surface of the slide rod 24. The end of the connecting rod a26 away from the slide rod 24 is hinged to the center near the outer connecting rod b27. The slide rod 24 passes through and is slidably connected to the inner wall of the fixed plate 21. Four sets of fixing blocks 25 are fixedly connected to the lower surface of the fixed plate 21. A sliding groove is opened on the surface of the slide rod 24, and the slide rod 24 is slidably connected to the outer surface of the fixing block 25. On the surface, two sets of connecting rods b27 are hinged to the lower surface of the fixing block 25. The end of the two sets of connecting rods b27 away from the fixing block 25 is hinged to the positioning block 28. By moving the slide rod 24 up and down, the connecting rod a26 hinged at its bottom end will pull the center of the connecting rod b27 near the inner side to move it outward or inward, so that the positioning block 28 moves outward or inward and contacts and limits the positioning groove at the top of the fan blade body 1, so that the fan blade body 1 can be quickly installed. The upper surface of the fan blade body 1 is provided with a positioning groove. The inner side wall of the positioning block 28 contacts the inner side wall of the positioning groove of the fan blade body 1. Four sets of top columns 29 are fixedly connected to the upper surface of the fixing plate 21. The upper surface of the top column 29 is provided with an adjustable installation component 3.

[0033] Reference Figures 3-4The adjustable mounting assembly 3 includes a mounting plate 31. A through annular groove is formed on the lower surface of the mounting plate 31. This groove allows a pre-drilled screw for the fan blade body 1 to pass through it. Guide grooves are formed on both sides of the annular groove. The mounting plate 31 is fixedly connected to the upper surface of the top post 29. The end of the self-locking screw 34 contacts the outer arc surface of the fixed post 32. The threaded engagement between the self-locking screw 34 and the sliding sleeve 33 provides self-locking capability. By passing through the sliding sleeve 33 and contacting the fixed post 32, the self-locking screw 34 can fix the sliding sleeve 33 at multiple positions as it moves up and down on the surface of the fixed post 32. The center of the bottom end of the mounting plate 31 is fixed. A fixed post 32 is connected, and a sliding sleeve 33 is slidably connected to the surface of the fixed post 32. A self-locking screw 34 is threaded through the inner wall of the sliding sleeve 33. A protrusion 35 is fixedly connected to the outer arc surface of the sliding sleeve 33. A hinge rod 36 is hinged to the surface of the protrusion 35. A mounting seat 37 is hinged to the end of the hinge rod 36 away from the protrusion 35. When the sliding sleeve 33 moves up and down, it will drive the protrusion 35 to move synchronously. Thus, the mounting seat 37 is pushed to slide inside the guide groove of the mounting plate 31 through the hinge rod 36. The angle of the mounting seat 37 can be adjusted according to the screw position reserved in the installation position. The top of the mounting seat 37 is slidably connected to the inner side wall of the guide groove of the mounting plate 31. An internal thread groove is opened at the center of the mounting seat 37.

[0034] Working principle: When installing the fan blade body 1, the electric telescopic rod 22 of the quick-release mechanism 2 is activated. The telescopic end of the electric telescopic rod 22 pushes the connecting plate 23 down, and the sliding rods 24 hinged at the four corners of the connecting plate 23 move down accordingly. The sliding rods 24 slide along the inner wall of the fixed plate 21 and the outer surface of the fixed block 25. The connecting rod a26 hinged to the lower surface of the sliding rod 24 moves down synchronously, pulling the center of the outer connecting rod b27 hinged at its end, so that the two sets of connecting rods b27 unfold outward, driving the positioning block 28 at the end of the connecting rod b27 to approach the positioning groove on the upper surface of the fan blade body 1, until the inner side wall of the positioning block 28 is in close contact with the inner wall of the positioning groove, thus completing the quick installation of the fan blade body 1. During disassembly, the electric telescopic rod 22 retracts, causing the connecting plate 23 to move upward. The sliding rod 24 pulls the connecting rod a26 upward, causing the connecting rod b27 to retract inward. The positioning block 28 disengages from the positioning groove, and the fan blade body 1 can be removed. The four sets of top columns 29 on the upper surface of the fixed plate 21 provide fixed support for the adjustable mounting assembly 3.

[0035] When installing the entire fan hanger structure, first adjust the adjustable mounting component 3 according to the position of the reserved screw at the installation location. Loosen the self-locking screw 34 on the inner wall of the sliding sleeve 33 so that the end of the self-locking screw 34 disengages from the outer arc surface of the fixing post 32, pushing the sliding sleeve 33 to move up and down along the fixing post 32. The protrusion 35 on the outer arc surface of the sliding sleeve 33 moves synchronously, pushing the mounting seat 37 to slide in the guide groove of the mounting plate 31 through the hinged hinge rod 36 until the internal thread groove at the center of the mounting seat 37 aligns with the reserved screw. Then, rotate the self-locking screw 34 in the opposite direction, using its thread self-locking property with the sliding sleeve 33 to press the end of the self-locking screw 34 against the fixing post 32, fixing the position of the sliding sleeve 33 and the mounting seat 37. Pass the reserved screw through the annular groove on the lower surface of the mounting plate 31 and thread it into the internal thread groove of the mounting seat 37 to complete the installation and fixing of the overall structure. The annular groove design can adapt to the circumferential position of different reserved screws.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
