Problems solved by technology
[0003] However, these ordinary casters with braking function are still in the process of moving, because the casters will rotate arbitrarily, so that the carrier is prone to uneven thrust due to the uneven thrust applied to the carrier during the straight-line displacement process, causing the carrier to move forward. The direction of displacement is not easily controlled
[0004] When the carrier is equipped with swivel casters, although the carrier can turn smoothly according to the requirements, there will be a defect that it is not easy to control the direction of the carrier's travel and displacement during the displacement process. For traditional casters (that is, fixed non-rotatable casters), although the carrier can be controlled in the direction of straight displacement, it is not easy to turn, so a caster structure with functions such as orientation and braking is required

Embodiment Construction
[0072] The caster structure of the present invention is as Figure 1 to Figure 7 Shown, including:
[0073] A main seat body 10, an axis 20, a directional mechanism 30, a brake mechanism 40, a reset pedal 50 and a wheel 60.
[0074] The main base 10 has a top shell 11, the top shell 11 includes an inner top shell 111 and an outer top shell 112, the main base 10 is relatively rotatable combined with the shaft 20, the shaft 20 One end of the shaft 20 extends into the main base body 10, and one end of the shaft 20 extends into the main base body 10 is fixedly sleeved with a first tooth member 21 and a second tooth member 22, the first tooth member 21 is provided A first groove 211, and the second clamping member 22 defines a second groove 221.
[0075] The directional mechanism 30 includes a directional pedal 31 and a first rocker 32. One end of the directional pedal 31 has a directional pedal 311, and the other end of the directional pedal 31 is formed with a first pressing portion 31...

The invention discloses a caster structure, which mainly includes a main base body, an axis, an orientation mechanism, a braking mechanism, a reset pedal, a first locking gear, a second locking gear and a wheel The main base body is relatively rotatable and combined with the shaft center. The first toothed part and the second toothed part are fixedly installed on the shaft center. By stepping on the directional pedal of the directional mechanism, the directional pedal is pushed against a first The seesaw, the first seesaw is clamped in the first groove of a first locking tooth, so that the caster can be oriented, and then by stepping on the brake pedal of the brake mechanism, the brake pedal is pushed against the second seesaw, so that The second clamping portion of the second seesaw is clamped in the second groove of the second locking tooth, and the third clamping portion of the second seesaw is clamped in the limiting gear of the wheel, so that the caster can be oriented and brakes. The invention also discloses a method for using the caster structure, through the method of the invention, the caster can perform functions such as steering, orientation, and braking.
Description
Technical field [0001] The present invention relates to casters, in particular to a caster structure with functions such as orientation and braking. The invention also relates to a method of using the above caster structure. Background technique [0002] Generally, in order to make the carrier (patient bed, precision instrument or workbench, etc.) move more convenient and labor-saving, casters are usually arranged under the carrier. The casters at the beginning are of a fixed non-rotatable design, so that the carrier can only move straight and cannot turn. For this reason, a rotary caster has been developed on the market to provide the function of turning when the carrier is displaced, and then in order to prevent the caster from moving by itself due to uneven ground or other factors when it is stationary, a design is designed. Equipped with casters with brake pedals, people can control the brake stop after the carrier is displaced. [0003] However, these ordinary casters with b...
