Foregoing invention create complex structure, manufacturing cost and later maintenance cost high, service life is short.

Utility model content

The purpose of this utility model is, overcomes the above-mentioned defect of prior art, provides a kind of structure simple, easy to use, has the castor of brake gear safely and effectively.

For achieving the above object, the technical scheme that the utility model provides is as follows: a kind of castor with brake gear, comprise the body be made up of wheel seat, caster and pulley, the outer rim of pulley is equipped with several spacing projections, the top of caster is provided with brake pedal, the bottom of brake pedal is provided with the brake projection coordinated with spacing projection, and brake pedal one end is connected with spring assembly, and this spring assembly is located on caster.

Further, several spacing projections are arranged at left side and the right side of pulley, and brake projection is arranged at the left side and the right of the bottom of brake pedal.

Further, spring assembly comprises male connection locations, female connection locations and spring, male connection locations, female locations that connects include the connection base with through hole, projection spring retention posts on the public connection base connecting locations, projection spring registration arm on female connection base connecting locations, spring housing is located at male connection locations and is connected between locations with mother, and spring retention posts inserts in the tube chamber of spring registration arm.

Usefulness of the present utility model is: user exerts a force to brake pedal, the brake projection of brake pedal is arranged between any two spacing projections of pulley, can brakes castor; By the reset of spring assembly, when user does not exert a force to brake pedal, brake pedal leaves spacing projection, and castor reverts to rotatable mobile status, structure is simple, easy to use, safe and effective, high-frequency access times can be stood, low cost of manufacture, long service life.
