Summary of the invention

Technical problem to be solved in the utility model be provide at above-mentioned prior art present situation a kind of open and draw in all very convenient, and safe and reliable hand push folding baby carrier.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of hand push folding baby carrier, comprise a pair of foreleg, place described foreleg below front-wheel, a pair of back leg, place trailing wheel, push rod and the seat cushion member of described back leg below, be provided with two spanner bars between described foreleg and the described back leg, the middle part of two spanner bars is hinged, the two ends of two spanner bars cross-articulation respectively are provided with between described a pair of back leg and unfold device on the back leg of the foreleg of a side and opposite side.

The described device that unfolds comprises a pair of horizontal fork arm of, a pair of horizontal fork arm down, a pair of oblique forked lever and a perpendicular fork arm, a described end of horizontal fork arm down is hinged, the lower end of described oblique forked lever is hinged on the bottom of described back leg with the other end of described down horizontal fork arm, the upper end of described oblique forked lever is hinged on the handle slide, described perpendicular fork arm passes described handle slide, a described end of horizontal fork arm and the upper articulation of described back leg, the upper end of described perpendicular fork arm and the described other end of horizontal fork arm are hinged on the eye ring seat together, the lower end of described perpendicular fork arm is provided with foot-operated, articulate on the described eye ring seat and be equipped with handle, described handle, be provided with lockout mechanism between described eye ring seat and the described handle slide.

Described lockout mechanism comprises the lock hole that is arranged on the described handle and is arranged on the protruding block that is fastened with described lock hole on the described handle slide, is provided with the elastic element that described protruding block is pressed into described lock hole between described handle and the described eye ring seat.

Described elastic element can be a torque spring, also can be other elastic element such as flexure strip.

Described push rod is provided with arm-rest frame, is provided with strut bar between described arm-rest frame and the described foreleg, and described strut bar one end is hinged on the described arm-rest frame, and the other end of described strut bar is hinged on the described foreleg.

Compared with prior art, advantage of the present utility model is the device that unfolds with lockout mechanism is set between a pair of back leg, opens and draw in all very convenient; When needs draw perambulator in, handle need only be pulled upwardly, make lock hole and the disengaging of the protruding block on the handle slide on the handle that is fastened mutually that locking is opened, upwards mention then to drive and go up horizontal fork arm, horizontal fork arm, oblique forked lever and the motion of perpendicular fork arm down, perambulator is drawn in to the centre; And perambulator need be opened the time, need only firmly make foot-operated moving downward, handle since the effect of torque spring make lock hole automatically with the handle slide on the mutual snapping of protruding block, realize automatically locking, also increased the safe reliability of use thus greatly.
