[0002] In the prior art, the casters of household storage carts are mainly universal movable casters without brakes, and the structure is not coordinated with household products, especially storage carts. When parked, they are prone to automatic sliding due to natural gravity due to uneven ground, which poses obvious safety hazards.

[0003] For example, Chinese patent publication number CN209719154U discloses a light-duty bracket hole-top brake caster, which includes a hollow rivet column and a top spring cover. The top spring cover is provided with a groove, is mounted on the hollow rivet column, and has a functional structure installed at the lower end; the functional structure includes: a steering part, a rotating wheel part and a brake part, the rotating wheel part is connected to the steering part and is located below the steering part, and the brake part is connected to the steering part and is located on the right side of the steering part; the steering part mainly includes: a bracket leg piece, a plurality of large steel balls with the same structure, a brake spring cover, and a plurality of small steel balls with the same structure.

[0004] However, in the above scheme, the roller is braked by the brake card against the roller, and the roller can still rotate after braking, which leads to the defect that the cart automatically slides under the action of natural gravity due to uneven ground, and the safety is not high.

[0027] See also Figure 1 , Figure 3-5 The brake device includes a plurality of fixing holes 15, which are all provided on the side wall of the sliding ring 9, and the plurality of fixing holes 15 are arranged in a circular array. A fixing ring 13 is fixedly connected to the side wall of the right fixing plate 4, and a plurality of fixing rods 14 are fixedly connected to the side wall of the fixing ring 13, and each fixing rod 14 is symmetrical to each fixing hole 15.

At the same time, multiple fixing rods 14 will enter the fixing hole 15, thereby braking the moving wheel 5 and preventing the moving wheel 5 from rotating.

[0028] See also Figure 1 , Figure 4-5 One end of each of the fixing rods 14 is tapered, so that the inclined side wall of the fixing rod 14 can slide into the fixing hole 15 along the side wall of the fixing hole 15, which is more convenient and quick.

[0032] The working principle of the utility model is as follows: the entire support wheel can be easily installed at the bottom of the cart support by setting the screw rod 3, and the sliding ring 9 is pulled to squeeze the spring 8 to be in a stressed state, and the sliding ring 9 drives the multiple fixing holes 15 to move, so that the multiple fixing rods 14 are separated from the fixing holes 15, and the sliding ring 9 drives the sliding block 16 to move at the same time. When the sliding block 16 moves to the side of the L-shaped slot 12, the sliding ring 9 is rotated so that the sliding ring 9 drives the sliding block 16 to enter the L-shaped slot 12. When the sliding block 16 enters the corner of the L-shaped slot 12, the sliding ring 9 is released, and the spring 8 squeezes the sliding ring 9 so that the sliding ring 9 drives the sliding block 16 to enter the bottom of the L-shaped slot 12, thereby fixing the sliding ring 9, and the bracket can be moved by the moving wheel 5. After the movement is completed, pull the sliding ring 9 to make the sliding block 16 enter the corner of the L-shaped slot 12, rotate the sliding ring 9 to make the sliding block 16 enter the sliding slot 11, and then release the sliding ring 9. The spring 8 will squeeze the sliding ring 9 so that the side wall of the sliding ring 9 is against the side wall of the fixing ring 13. At the same time, multiple fixing rods 14 will enter the fixing hole 15, thereby braking the moving wheel 5, making the moving wheel 5 unable to rotate, thereby preventing the moving wheel 5 from rolling on its own when the ground is uneven.
