The utility model has the following beneficial effects:
according to the utility model, a user can control the L-shaped brake pad to lift by rotating the knob, so that the brake part of the L-shaped brake pad which lifts is tightly attached to or away from the tire wall of the tire, braking or loosening is realized, the action of the caster is controlled, and the operation is simple.
According to the utility model, the return spring is used for returning, so that the braking part of the L-shaped brake pad is always kept away from the tire, the tire is ensured not to be blocked, and the tire slides more smoothly.
According to the utility model, the brake part adopts the wear-resistant brake rubber sheet, so that the service life of the L-shaped brake pad is greatly prolonged.

Detailed Description
The utility model is further described with reference to the following figures and examples:
the embodiment is shown in fig. 1 to 6, and the caster structure with the brake comprises a support 1, a tire 2, a brake device, a bolt 4 and a nut 5, wherein the support 1 is provided with a tire accommodating cavity 11, an opening 12 is formed in the side wall of the support 1 corresponding to the tire accommodating cavity 11, and the tire 2 is arranged in the tire accommodating cavity 11.
Brake equipment includes L type brake block 6, knob 7 and reset spring (not shown in the figure), L type brake block 6 is L type iron sheet, and L type brake block 6 includes brake portion 8 and promotion portion 9, be provided with turn-ups 91 on the promotion portion 9, brake portion 8 passes opening 12 and stretches into in the tire holding chamber 11 and be located tire 2 top, and brake portion 8 is close to the child wall position of tire 2 and is provided with wear-resisting brake rubber piece 81, and promotion portion 9 is located the lateral wall of support 1 simultaneously, and promotion portion 9 control L type brake block 6 goes up and down, and opening 12 restriction promotes the moving direction and the lift distance of portion 9.
One end of the reset spring is connected with the support 1, the other end of the reset spring is connected with the pushing part 9, and the reset spring forms a reset mechanism of the L-shaped brake pad 6.
The knob 7 is a horizontal iron sheet, an arc convex part 71 is arranged at the central position of the horizontal iron sheet, handles 72 are arranged at two ends of the horizontal iron sheet, and the knob 7 is movably arranged on the side wall of the bracket 1.
