Detailed Description

The invention is further described below with reference to the accompanying drawings.

As shown in fig. 1, 2 and 3, an automatic resetting caster comprises a fixed seat plate 1, a brake fluted disc 2, a brake bracket 3, a pot nail 4, a wheel body 5 and a brake device, wherein the brake bracket 3 comprises a cylindrical seat part 31 with a lower opening, a brake seat part 32 and wheel carriers 33 positioned on two sides of the brake seat part, a top circular track with a lower opening is positioned on the fixed seat plate 1, an upper circular track with an upper opening and a lower circular track with a lower opening are positioned on a top plate of the cylindrical seat part 31, a bottom circular track on the upper surface of the brake fluted disc 2, the pot nail 4 is fixedly connected with the fixed seat plate 1 and the brake fluted disc 2, a top plate of the cylindrical seat part 31 is positioned between the fixed seat plate 1 and the brake fluted disc 2, a steel ball 6 is arranged between the top circular track and the upper circular track, and a steel ball 6 is arranged between the lower circular track and the bottom circular track; the braking fluted disc 2 is positioned in the cylindrical seat part 31, and the wheel body 5 is pivoted with the wheel frame 33; as shown in fig. 3 and 7, the brake device includes a brake pedal 71 and a brake manganese sheet 72.

A through hole 311 is arranged on the wall plate of the cylindrical seat part 31, and a connecting column 312 is arranged in the through hole;

also comprises a fixed shaft 8 and a tension spring 9,

the upper end of the fixed shaft 8 is fixedly connected with the pot nail 4, a hook part at one end of the tension spring 9 is matched with the connecting column 311, and a hook part at the other end of the tension spring 9 is in running fit with the fixed shaft 8.

An annular concave part is arranged on the connecting column 311, and an annular groove 81 is arranged at the lower part of the fixed shaft 8;

the hook part at one end of the tension spring 9 is matched with the annular concave part, and the hook part at the other end of the tension spring is matched with the annular groove 81.

When the brake device is used, the brake device is fixed at four corners of a bottom plate of a movable box, and four corners of a top plate of the superposed movable boxes are provided with positioning grooves, as shown in fig. 2, a set brake bracket 3 and a wheel body 5 are in a fixed direction A relative to a fixed seat plate 1; when walking, when encountering a corner or an obstacle, as shown in fig. 2, the braking bracket 3 and the wheel body 5 rotate a certain angle relative to the fixed seat plate 1, as shown in the state B in fig. 2; the tension spring 9 is stretched and lengthened;
