[0024] Reference Figure 1-4 A brake wheel of a multifunctional transport vehicle comprises a support frame 1, a connecting column 11, a wheel 12, two arc-shaped plates 2, two pedals 4 and two brake plates 3. The connecting column 11 is rotatably mounted on the top of the support frame 1, and the wheel 12 is rotatably mounted in the support frame 1. Two support shafts 21 arranged parallel to each other are rotatably mounted in the support frame 1. The two arc-shaped plates 2 are respectively fixedly mounted on the corresponding support shafts 21, and the two arc-shaped plates 2 are symmetrically arranged. The two support shafts 21 extend to the front side of the support frame 1 and are respectively fixedly sleeved with transmission gears 22. The two transmission gears 22 are meshed with each other, so that the two arc-shaped plates 2 on both sides can keep synchronous and reverse rotation. An arc groove 201 is provided on the side of the arc plate 2 close to the wheel 12, and two card slots 202 are provided in the arc groove 201. Two card blocks 31 are fixedly mounted on the brake plate 3, and the two card blocks 31 are respectively card-engaged in the corresponding card slots 202, and the brake plate 3 is card-engaged in the arc groove 201, which can The brake plate 3 is preliminarily installed and positioned. Two limiting bolts 32 are threadedly installed on the arc plate 2. The two limiting bolts 32 are respectively threadedly connected with the corresponding clamping blocks 31, which can effectively fix the brake plate 3 and also facilitate the quick disassembly and replacement of the brake plate 3. Two mounting grooves are provided on the support frame 1. Rotating rods 41 are rotatably installed in the two mounting grooves. The two pedals 4 are radially fixedly installed on the corresponding rotating rods 41 respectively. The pedal 4 and the arc plate 2 on the same side are hingedly installed with the same support rod 42. Limiting grooves 52 are provided in the two mounting grooves. A strip-shaped opening is provided on the pedal 4. A U-shaped plate 51 is damped and slidably installed in the strip opening. A limiting plate 5 is fixedly installed on the U-shaped plate 51. The bottom side of the limiting plate 5 is in sliding contact with the top side of the pedal 4, and the limiting plate 5 is adapted to the limiting groove 52 on the corresponding side, so that the pedal 4 can be limited after stepping on the pedal 4, so that the brake plate 3 and the wheel 12 can maintain a braking state.

[0025] In this embodiment, in order to enable the pedal 4 to automatically deflect upward when the limit on the pedal 4 is released, thereby realizing automatic resetting of the pedal 4, and then driving the arc plate 2 through the support rod 42 to make the brake plate 3 and the wheel 12 out of the braking state, a circular groove is opened on the front side of the pedal 4 based on the rotating rod 41 as the center, and a torsion spring 43 is fixedly installed in the circular groove. The torsion spring 43 is movably mounted on the outside of the rotating rod 41 and fixedly connected to the inner wall of the installation groove.

[0026] In this embodiment, a rectangular opening is opened on the front side of the support frame 1, and the two transmission gears 22 are both located in the rectangular opening, which can prevent the transmission gears 22 from being damaged by collision during the use of the brake wheel 12.

[0027] Working principle: When using the brake wheel of the multifunctional transport vehicle, when braking is needed, step on the pedal 4 downward, and the pedal 4 controls the curved plate 2 to deflect toward the direction close to the wheel 12 based on the support shaft 21 through the support rod 42 and contact the wheel 12, thereby braking the wheel 12. In this process, with the cooperation of the support shaft 21 and the transmission gear 22, the curved plates 2 on both sides can be synchronously deflected in the opposite direction, so that the brake plates 3 on both sides can be controlled to synchronously participate in the braking of the wheel 12, thereby achieving a relatively stable braking effect. When it is necessary to maintain the braking state, use the sole of the foot to push the limit plate 5 upward along the pedal 4 into the limit groove 52. When it is necessary to release the brake, move the limit plate 5 out of the limit groove 52 and lift the pedal 4. Under the action of the torsion spring 43, the pedal 4 can drive the curved plate 2 to deflect upward and reset through the support rod 42, so that the brake plate 3 can be out of contact with the wheel 12 and achieve the effect of releasing the braking of the wheel 12.

[0028] When the brake plate 3 needs to be replaced, the limiting bolt 32 is turned to disengage the threaded connection between the limiting bolt 32 and the block 31, and then the brake plate 3 is removed from the arc plate 2 to be replaced. After the replacement is completed, the new brake plate 3 is clamped and installed on the arc plate 2, and the limiting bolt 32 is turned to make the limiting bolt 32 and the block 31 threadedly connected to effectively fix the brake plate 3, thereby improving the convenience of using the brake wheel.
