[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Specific examples are given below.

[0022] See also Figure 1 to Figure 7 In the embodiment of the utility model, an adjustable angle chassis assembly of an industrial fan includes a chassis 1, a hood 2, a blade connecting plate 3, a ring gear 4, a bevel gear 5, a bearing seat 6, a locking mechanism 7 and a bearing 8. A plurality of blade connecting plates 3 are installed on the chassis 1. The front end of each blade connecting plate 3 is fixedly connected to a rotating shaft 301. A connecting hole 101 is provided on the chassis 1. When in use, the output shaft of the motor is installed into the connecting hole 101, and the blade is fixed to the blade connecting plate 3. Each rotating shaft 301 passes through two bearing seats 6 and a locking mechanism 7. The bearing seat 6 and the locking mechanism 7 are detachably fixed to the chassis 1 by bolts, so that the bearing seat 6 and the locking mechanism 7 can be installed and disassembled. The rotating shaft 301 is rotatably connected to the bearing seat 6 through the bearing 8. Then, a bevel gear 5 is installed at the front end of each rotating shaft 301, and a ring gear 4 is rotatably connected in the chassis 1, and the bevel gear 5 is meshed with the ring gear 4. A hood 2 for covering the ring gear 4 and the bevel gear 5 is installed on the chassis 1. The locking mechanism 7 includes: a locking sleeve 701 and a clamping handle 702. The rotating shaft 301 passes through the locking sleeve 701, and the right half of the locking sleeve 701 is installed with the clamping handle 702. The clamping handle 702 is connected to the locking sleeve 701 through a thread, and the right half of the locking sleeve 701 is provided with an adjustment gap 703. When in use, tighten the clamping handle 702 so that the adjustment gap 703 is gradually compressed and reduced, thereby reducing the inner diameter of the locking sleeve 701, so that the rotating shaft 301 in the locking sleeve 701 is clamped so that it cannot rotate.

[0023] Each bearing seat 6 is provided with a slot 601 for clamping the outer ring of the bearing 8, and the front side of each bearing 8 is provided with a retaining ring 9, which is installed on the rotating shaft 301. When the bearing 8 is installed in the bearing seat 6, the slot 601 and the retaining ring 9 are used to limit the bearing 8 to prevent the bearing 8 from falling off.

[0024] Working principle: When adjusting the adjustable angle chassis assembly of the industrial fan, first loosen the clamping handle 702 to allow the shaft 301 to rotate, then rotate a blade connecting plate 3 by hand, and drive the shaft 301 and the bevel gear 5 to rotate through the blade connecting plate 3, and drive the ring gear 4 to rotate through the bevel gear 5, and drive other bevel gears 5, the shaft 301 and the blade connecting plate 3 to rotate together through the ring gear 4, so as to adjust the inclination angle of multiple blade connecting plates 3 at the same time. After adjustment, tighten the clamping handle 702 to clamp the shaft 301 into the locking sleeve 701 so that the shaft 301 cannot rotate. Finally, fix the blades to the blade connecting plate 3 with bolts so as to adjust the inclination angle of the blades as needed.
