A rotating block 14 is rotatably connected between the inner walls of both sides of the fixing frame 16. A nozzle 15 is fixed to the bottom of the rotating block 14 by a thread, and the nozzle 15 is connected to the liquid dispensing pipe 4. An external pipe 5 is provided on the top of the frame body 1, and the external pipe 5 is connected to the liquid dispensing pipe 4 and rotatably connected. The outer walls of both sides of the fixing frame 16 are provided with a limit assembly for limiting the spraying angle of the nozzle 15. The wheel hub is placed on the placement plate 2, and the external pipe 5 is started with the water pump connected to the outside, so that the external water source enters the liquid dispensing pipe 4 through the external pipe 5 and is sprayed through the nozzle 15. The nozzle 15 is driven to rotate by the power mechanism, so that the contact area between the nozzle 15 and the wheel hub becomes larger, avoiding the occurrence of a dead angle of spraying. The height between the wheel hub and the nozzle 15 is changed by the adjusting mechanism, and then the position of the water spraying is changed, thereby improving the cleaning effect of the device, so that different wheel hubs can be sprayed and cleaned in the same way, thereby improving the applicability of the device.

[0024] In the present utility model, the adjustment mechanism includes a cylinder 10, which is fixed to one side of the frame 1 by bolts. The top of the cylinder 10 is fixed with a connecting frame 9 by bolts, and the connecting frame 9 is fixed to the placement plate 2. When the cylinder 10 is started, the cylinder 10 drives the connecting frame 9 and the placement plate 2 to rise or fall at the same time, thereby changing the height of the wheel hub and the nozzle 15, and then changing the horizontal spray position of the cleaning fluid sprayed by the nozzle 15.

[0025] Among them, the power mechanism includes a motor, which is fixed to the top outer wall of the frame 1 by bolts. The output shaft of the motor passes through the frame 1 and is keyed to the driving wheel 12, and the driving wheel 12 is engaged with the driven wheel 11. When the motor is started, the motor drives the driving wheel 12 to rotate, and the driving wheel 12 is engaged with the driven wheel 11, thereby rotating the driven wheel 11, and then rotating the nozzle 15, changing the spraying position of the nozzle 15, avoiding the situation where the nozzle 15 sprays on the dead corner of the wheel hub and cannot spray, and further improving the cleaning effect of the device.

[0026] Among them, the limiting assembly includes two rotating shafts 18, which are respectively welded to both sides of the rotating block 14. One end of the two rotating shafts 18 passes through the fixing frame 16 and is welded with a torsion spring 17, and the other end of the torsion spring 17 is fixed to the fixing frame 16. The torsion force generated by the torsion spring 17 can offset the gravity generated by the change in the angle between the nozzle 15 and the rotating block 14, so that the nozzle 15 can remain in one position for a long time. A guide rod 22 is welded on one side of the rotating block 14, and a screw rod 20 is sleeved on the outer wall around the guide rod 22. An annular surface 21 is welded on one end of the screw rod 20, and the annular surface 21 can contact one side of the frame 1. The circumferential outer wall of the screw rod 20 is threadedly connected to a threaded tube 19, and the thread The tube 19 is rotatably connected to the rotating block 14 through a groove. By rotating the threaded tube 19, the screw rod 20 is moved under the action of the thread and the guide rod 22, thereby changing the distance between the annular surface 21 and the rotating block 14, and then when the annular surface 21 contacts the frame 1, the spray angle of the nozzle 15 is changed. During the rotation of the liquid dispensing tube 4, the rotation of the liquid dispensing tube 4 will drive the nozzle 15 and the fixed frame 16 to rotate, thereby driving the threaded tube 19, the screw rod 20 and the annular surface 21 to rotate. During the rotation of the annular surface 21, the annular surface 21 will contact the frame 1, so that the frame 1 will squeeze the annular surface 21 and the rotating block 14 to rotate, thereby changing the spray angle of the nozzle 15, further improving the cleaning range of the device.

[0027] Among them, one side of the dispensing tube 4 is welded with the same number of baffles 13 as the spraying, and the baffles 13 are in contact with the threaded tube 19 to prevent the centrifugal force generated during the rotation of the dispensing tube 4 from causing the angle of the nozzle 15 to change too much, thereby preventing the spray from reaching the wheel hub.

[0028] The working principle of the utility model is as follows: when in use, the wheel hub is placed on the placement plate 2, the external pipe 5 is started with the water pump connected to the outside, so that the external water source enters the liquid distribution pipe 4 through the external pipe 5 and is sprayed out through the nozzle 15, the motor is started, the motor drives the driving wheel 12 to rotate, the driving wheel 12 is engaged with the driven wheel 11, so that the driven wheel 11 rotates, and then the nozzle 15 rotates, changing the spraying position of the nozzle 15, so that the contact area between the nozzle 15 and the wheel hub becomes larger, avoiding the occurrence of spraying dead angles, and starting the cylinder 10, which drives the connecting frame 9 and the placement plate 2 to rise at the same time Or lowered, thereby changing the height of the wheel hub and the nozzle 15, and then changing the position where the water is sprayed. During the rotation of the dispensing tube 4, the rotation of the dispensing tube 4 will drive the nozzle 15 and the fixing frame 16 to rotate, thereby driving the threaded tube 19, the screw rod 20 and the annular surface 21 to rotate. During the rotation of the annular surface 21, the annular surface 21 will contact the frame 1, so that the frame 1 will squeeze the annular surface 21 and the rotating block 14 to rotate, thereby changing the spray angle of the nozzle 15, further improving the cleaning range of the device, so that different wheel hubs can be sprayed and cleaned in the same way, and improving the applicability of the device.
