Abstract
The present invention relates to a locking mechanism of wheels of carriages for children, which comprises wheels [3], a wheel shaft [7] and a locking groove [2]. The present invention is characterized in that the side parts of the wheels [3] are provided with ratchet wheels [6]; treading grip covers [12] with ratchet pawls [18] are sheathed outside the ratchet wheels [6], and the ratchet pawls [18] and the ratchet wheels [6] are engaged; slide blocks [14] with locking pins [10] are arranged in the inner cavities of the ratchet wheels [6] which are provided with convex blocks [13]; the slide blocks [14] are provided with guiding grooves [16] with guiding slopes [11]. Because both of a braking condition and a release condition are realized by downward treading actions, the present invention is convenient to the downward treading operation of soles.
Description
The present invention relates to the lockout mechanism of the wheel of a kind of doll carriage, particularly perambulator.
In the prior art, the lockout mechanism of pushchair, comprise wheel, with the central authorities of wheel rotate the bonded assembly axletree, be arranged at a plurality of lock slots that are circle distribution on the wheel, side at wheel is provided with the brake step that is connected with vehicle frame, when stepping the brake step downwards, the brake shoes that is connected in the brake step inserts in the lock slots, and wheel can not be rotated.When the needs release, need upwards hook the brake step with instep, make the brake shoes groove that goes out of lock, two kinds of actions are up and down arranged during this lock mechanism operative, with pin operation inconvenience, easy damaged, the vamp of making dirty, particularly easier damage instep surface when being installed with the footwear of instep exposure.
The object of the present invention is to provide a kind of lockout mechanism that can finish the pushchair of brake locking or release action when stepping on step downwards.
Technical scheme of the present invention is: a kind of lockout mechanism of pushchair, comprise wheel, with the central authorities of wheel rotate the bonded assembly axletree, be arranged at a plurality of lock slots that are circle distribution on the wheel; The sidepiece of described wheel is provided with can be around the ratchet of axletree rotation, described ratchet is with outward can be around the grip of stepping on of ratchet rotation, described stepping on is provided with ratchet putting, described ratchet is meshed with ratchet on the described ratchet excircle, described stepping on stepped on handle putting the brake that is connected with radially extension, and described stepping on is connected with retracing spring putting; Being provided with in the inner chamber of described ratchet can axially movable slide block, side towards wheel of this slide block is fixed with at least one axial stop pin, this stop pin passes the lock pin holes of the car leg outer cover that is connected with the car leg, and under lock-out state, be inserted in the described lock slots, the sidepiece of described slide block is provided with and makes stop pin be tending towards the stage clip that the direction to wheel moves; The internal chamber wall of described ratchet is provided with the projection of at least one radial protrusion, the outside face of described slide block is provided with a side-wall shaft to straight guide groove, another sidewall of described guide groove is provided with guiding surface, and described projection is inserted in the described guide groove under lock-out state.Depressing the brake step on after, step on interplanting is clockwise rotated, then step on the ratchet promotion ratchet that puts is also clockwise rotated, when the projection on the ratchet goes in the guide groove on the slide block, slide block slides to the wheel direction under the impetus of stage clip, and the stop pin Chinese juniper is advanced in the lock slots of wheel, checks wheel, and brake to step on conter clockwise under the effect of retracing spring is resetted, finish lock-out state.Stepping on brake again when stepping on, stepping on grip remakes and clockwise rotates, then step on and the ratchet that puts is promoted a ratchet also remake and clockwise rotate, projection on the ratchet overcomes stage clip along guiding surface in guide groove pressure is also made cw and is slided, make slide block to retreating, drive the stop pin leg and go out lock slots, discharge wheel away from the wheel direction, finish released state, and projection is blocked at the slide block end face of the close wheel of slide block.Brake is stepped on resetting under the effect of retracing spring, so goes round and begins again, and can realize locking the state and the released state of wheel.
The present invention compared with prior art has following advantage:
Brake and release position all are the actions of stepping on down, and what be convenient to sole steps on operation down, and manner of execution is simple, operates easily.
The invention will be further described below in conjunction with drawings and Examples:
