DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. The described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments of the utility model, other embodiments obtained by ordinary technicians in this field without making creative work are all within the scope of protection of the utility model.

[0024] Reference Figure 1-Figure 4, an adjustable multi-head fan assembly, comprising a support rod 1, the circumferential outer wall of the support rod 1 is rotatably connected to two rotating drums 2, one side of the two rotating drums 2 is provided with a locking assembly for fixing the rotating drums 2, the outer walls of the other sides of the two rotating drums 2 are welded with a supporting rod 3, the top of the supporting rod 3 is fixed with a fixing disk 6 by bolts, the top of the fixing disk 6 is rotatably connected with a rotating disk 7, the outer side of the fixing disk 6 is provided with a fixing assembly for fixing the rotating disk 7, the top of the rotating disk 7 is fixed with a U-shaped frame 8 by bolts, both sides of the U-shaped frame 8 are provided with through holes 17, a fan head 9 is provided in the U-shaped frame 8, both sides of the fan head 9 are fixed with connecting rods 18 by bolts, and the connecting rods 18 are rotatably connected with the through holes 17, and the top of the U-shaped frame 8 is provided with a plug-in assembly for fixing the connecting rod 18, so that the lock The tightening assembly no longer locks the rotating drum 2, so the rotating drum 2 can be rotated to adjust the angle of the entire assembly. When the angle of the fan head 9 needs to be adjusted separately, the fixing assembly no longer fixes the rotating disk 7, and the rotating disk 7 can be rotated at this time. The rotating disk 7 will drive the U-shaped frame 8 to rotate. At this time, the rotating disk 7 can be rotated, and the rotating disk 7 will drive the U-shaped frame 8 to rotate. Since the plug-in assembly fixes the connecting rod 18, the U-shaped frame 8 will drive the fan head 9 to rotate through the connecting rod 18. Then the plug-in assembly no longer fixes the connecting rod 18. At this time, the fan head 9 in the U-shaped frame 8 can be rotated through the connecting rod 18, so that the fan head 9 can be rotated separately, and the angle of the fan head 9 can be adjusted separately, thereby improving the use effect of the multi-head fan assembly.

[0025] In the utility model, the locking assembly includes two threaded holes, which are respectively opened on one side of the two rotating drums 2. The two threaded holes are threadedly connected with a threaded rod 4, and the threaded rod 4 is in contact with the support rod 1. A knob 5 for rotating the threaded rod 4 is welded at one end of the threaded rod 4. The threaded rod 4 is rotated by the knob 5 to make the threaded rod 4 disengage from the support rod 1 and no longer lock the rotating drum 2. The fixing assembly includes a plurality of card grooves 13, and the plurality of card grooves 13 are evenly opened on the circumferential outer wall of the fixed disk 6. A avoidance groove 11 is opened on one side of the rotating disk 7, and a card block 12 is arranged in the avoidance groove 11, and the card block 12 is engaged with the card groove 13. A slide groove 15 is opened on one side of the avoidance groove 11, and the slide groove 15 The inner sliding connection is provided with a slide bar 14, and one end of the slide bar 14 extends into the avoidance groove 11 and is fixed with the block 12. The circumferential outer wall of the slide bar 14 is sleeved with a spring 16, and the two ends of the spring 16 are fixed with the slide groove 15 and the slide bar 14. One side of the block 12 is fixed with a handle for pulling the block 12 to move by bolts. The block 12 is pulled by the handle to move so that the block 12 is disengaged from the groove 13 and the avoidance groove 11. At this time, the rotating disk 7 can be rotated. In the process of pulling the block 12 to move, the block 12 will drive the slide bar 14 to move out of the groove 15, and the slide bar 14 will squeeze the spring 16. When the fan head 9 is rotated to a suitable angle, the block 12 is released. At this time, the spring 16 will push The slide bar 14 is reset, and the slide bar 14 will drive the card block 12 to move into the avoidance groove 11 and make the card block 12 engage with the corresponding card slot 13 to fix the angle of the fan head 9. The two sockets of the plug and assembly are both opened at the top of the U-shaped frame 8. The two sockets are plugged with a card rod 21, and a fixing block 20 is welded on the top of the card rod 21. The circumferential outer wall of the card rod 21 is sleeved with a tension spring 22, and the two ends of the tension spring 22 are respectively fixed to the fixing block 20 and the U-shaped frame 8. The circumferential outer wall of the connecting rod 18 is provided with a plurality of bayonet holes 19, and the card rod 21 is plugged with the bayonet hole 19. When the card rod 21 is pulled to move upward, the card rod 21 will drive the fixing block 20 to move upward and disengage from the bayonet hole 19 At the same time, the fixing block 20 will stretch the tension spring 22, and the fan head 9 can be rotated at this time. When the fan head 9 is rotated to a suitable angle, the clamping rod 21 is released. At this time, the tension spring 22 will pull the fixing block 20 to move downward, and the fixing block 20 will drive the clamping rod 21 to move downward, so that the clamping rod 21 enters the relatively aligned clamping slot 19 to fix the angle of the fan head 9. The top of the support rod 1 is fixed with a lighting lamp 10 by bolts. When the multi-head fan assembly is used at night, the lighting lamp 10 can be turned on. The lighting lamp 10 will be able to provide light for the multi-head fan assembly at night. The bottom end of the support rod 1 is fixed with a support seat by bolts, and the support seat is round, and the support seat can increase the contact area with the ground.

[0026] Working principle: when adjustment is needed, the threaded rod 4 is rotated through the knob 5 so that the threaded rod 4 is disengaged from the support rod 1 and the rotating drum 2 is no longer locked. At this time, the rotating drum 2 can be rotated to adjust the angle of the entire assembly. When the angle of the fan head 9 needs to be adjusted separately, the block 12 is pulled to move so that the block 12 is disengaged from the slot 13 and the avoidance slot 11. At this time, the rotating disk 7 can be rotated, and the rotating disk 7 will drive the U-shaped frame 8 to rotate. At this time, since the block 21 is inserted into the bayonet 19 on the connecting rod 18, the U-shaped frame 8 will drive the fan head 9 to rotate through the connecting rod 18. In the process of pulling the block 12 to move, the block 12 will drive the slide bar 14 to move out of the slide slot 15, and the slide bar 14 will squeeze the spring 16. When the fan head 9 is rotated to a suitable angle, the block 12 is released. At this time, the spring 16 will push the slide bar 14 to reset, and the slide bar 14 will return to its original position. The rod 14 will drive the block 12 to move into the avoidance groove 11 and make the block 12 engage with the corresponding slot 13 to fix the angle of the fan head 9. Then the card rod 21 can be pulled to move upward, and the card rod 21 will drive the fixing block 20 to move upward and disengage from the bayonet 19. At the same time, the fixing block 20 will stretch the tension spring 22. At this time, the fan head 9 in the U-shaped frame 8 can be rotated through the connecting rod 18. When the fan head 9 is rotated to a suitable angle, the card rod 21 is released. At this time, the tension spring 22 will pull the fixing block 20 to move downward, and the fixing block 20 will drive the card rod 21 to move downward, so that the card rod 21 enters the relatively aligned bayonet 19 to fix the angle of the fan head 9, so that the fan head 9 can be rotated independently and the angle of the fan head 9 can be adjusted independently, thereby improving the use effect of the multi-head fan assembly.
