Detailed Description
In the description of the present invention, it is to be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and to simplify the description, but do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore should not be construed as limiting the present invention.
Referring to fig. 1 and 2, a caster brake structure includes a mounting base 1, a brake structure, and a bracket 2 connected to the mounting base 1. The mounting seat 1 is rotatably connected with the support 2, and the mounting seat 1 is used for mounting a fixed caster. The support 2 is connected with a wheel body 3, and the brake structure comprises a pedal 4, a push rod 5 and a brake elastic sheet 6. The push rod 5 is longitudinally arranged at the axis of the relative rotation of the bracket 2 and the mounting seat 1 in a sliding manner. Specifically, the installation seat 1 is provided with a push rod base 7 at the axis of relative rotation, and the push rod base 7 is slidably sleeved with the push rod 5. The pedal 4 is hinged with the mounting seat 1, and the pedal 4 can control the push rod 5 to slide longitudinally. Specifically, the pedal 4 can directly control the push rod 5 to slide longitudinally, or control the push rod 5 to slide longitudinally through connecting other parts. The brake elastic sheet 6 is connected with the support 2, the brake elastic sheet 6 keeps the trend of moving towards the push rod 5, and the brake elastic sheet 6 is abutted to the push rod 5. The push rod 5 keeps the upward movement trend under the elastic acting force of the brake elastic sheet 6, so that the brake is always in a loose state.
The brake operation is very convenient, the pedal 4 is arranged on the mounting seat 1, so that the pedal 4 is always positioned at the same position and cannot rotate along with the bracket 2, and when the brake is needed, the brake can be carried out without observing the position of the pedal 4; and footboard 4 is in same position, and a plurality of truckles accessible series brake structure carry out the brake simultaneously, improve holistic brake stability and brake efficiency.
Further, the push rod 5 is provided with a brake adjusting piece, and the brake adjusting piece is arranged at the bottom of the push rod 5. The brake adjusting part adjusts the strength of the brake by adjusting the length of the brake adjusting part, so that brake failure is prevented.
Further, the brake adjusting part comprises a nut 8 and a bolt 9, the bolt 9 is in threaded connection with the push rod 5, the nut 8 is arranged between the bolt 9 and the push rod 5, and the nut 8 is in threaded connection with the bolt 9. This embodiment simple structure, reliable through the rotation regulation bolt 9 and nut 8, just can adjust the brake intensity of this embodiment.
Further, the pedal 4 is hinged with a pulling plate 10. One end of the pulling plate 10 opposite to the pedal 4 is in a V shape and is abutted against the upper part of the push rod 5. The push rod 5 is provided with a limiting surface 11 matched with the pull plate 10, and the pull plate 10 is arranged in the mounting seat 1 in a sliding mode. The pulling plate 10 is designed to keep the brake state all the time when the brake is performed.
The working principle is as follows: when the pedal 4 rotates downwards, the pedal 4 pulls the pulling plate 10 to slide outwards, one end of the pulling plate 10 in the shape of the Chinese character 'V' extrudes the push rod 5 to slide downwards, and further extrudes the brake elastic sheet 6 to be abutted against the wheel body 3, so that the brake is in a brake holding state;
when the pedal 4 rotates upwards, the pedal 4 pushes the pulling plate 10 to slide inwards, the push rod 5 and the brake elastic sheet 6 move upwards under the elastic acting force of the brake elastic sheet 6, so that the brake elastic sheet 6 is not abutted against the wheel body 3, and the brake state of the embodiment is released.
Furthermore, the limiting surface 11 is provided with a groove, and a rolling column 12 is movably connected in the groove. The rolling column 12 can reduce the resistance and abrasion of the relative movement between the push rod 5 and the pull plate 10, so that the embodiment is more durable and the braking operation is smoother.
Further, a torsion spring 13 is arranged at the hinged position of the pedal 4 and the pulling plate 10, and two ends of the torsion spring 13 respectively abut against the pulling plate 10 and the pedal 4. Under the elastic action of the torque spring 13, the pulling plate 10 and the pedal 4 will not be loosened and collapsed, so that the noise of the embodiment is smaller, and the noise reduction effect is achieved.
The above embodiments do not limit the scope of the present invention, and those skilled in the art can make equivalent modifications and variations without departing from the overall concept of the present invention.
