Detailed description of the invention

As Figure 1-10 shows, the buckle structure of the Pushchair described in the utility model embodiment, comprise rear foot assembly 7, when being applied in stroller, first, the structure of this perambulator is, bottom handle assembly 1, two ends arrange a Telescopic Fixed bayonet lock 113 respectively, simultaneously, bottom this handle assembly 1, a telescopic tube 2 is installed at two ends, every root telescopic tube 2 upper end sets up a telescopic tube draw-in groove 211 respectively, and the telescopic tube draw-in groove 211 that described Telescopic Fixed bayonet lock 113 snaps in corresponding side is inner, thus is fixedly connected with telescopic tube 2 by handle assembly 1;

Correspondingly, described handle assembly 1 is made up of two pipe links and a fixed sleeving, the upper and lower both sides of fixed sleeving are wherein offered a two road button 111, successively respectively and are folded button 112, connect bottom this two roads button 111 and fold button 112 and for discharging the two road lock functions folding button 112, the button 112 that folds wherein connects two Telescopic Fixed bayonet locks 113 respectively by bracing wire, discharges Telescopic Fixed bayonet lock 113 make it to be separated with the telescopic tube draw-in groove 211 of corresponding side by bracing wire.

Above-described two telescopic tube 2 lower ends are separately fixed on the fixing end face in joint, rear foot assembly 7 two tops 712, each joint 712 upper/lower terminal arranges one group of fixed pin holes respectively, the fixed pin holes fixed installation of upper end folds attaching parts 4, the fixed pin holes fixed installation forward foot in a step assembly 6 of lower end, described in fold and between attaching parts 4 and rear foot assembly 7, bracket of rear mounting 3 be installed and between this three, surround a delta-shaped region;

Correspondingly, described in fold outside attaching parts 4 and connect with seating attachment couplings 5, each inboard, joint 712 arranges and folds tongue 711, and this folds tongue 711 lower end linking springs 713.

As Figure 1-10 shows, the buckle structure of the Pushchair described in the utility model embodiment, traditional approach is fold tongue 711 with bracing wire direct pull to make it depart from rear foot assembly 7 to the direction of handle assembly 1, completes unblock; This structure breaks traditions way, unblock is completed: employing folds button 112 and connects two Telescopic Fixed bayonet locks 113 respectively by bracing wire by new type of drive, discharge Telescopic Fixed bayonet lock 113 by bracing wire to make it to be separated with telescopic tube draw-in groove 211 buckle of corresponding side, after Telescopic Fixed bayonet lock 113 is separated with telescopic tube draw-in groove 211, handle assembly 1 followed by telescopic tube 2 inside and down passes, shock folds tongue 711, makes to fold tongue 711 and is down separated telescopic tube 2; After telescopic tube 2 is separated with rear foot assembly 7, folds tongue 711 and be reset to original position under the elastic force of spring 713; When combining, telescopic tube 2 is drawn close to rear foot assembly 7, when be brought to fold tongue 711 position time, fold tongue 711 and press down, folding the inside of tongue 711 bullet to telescopic tube 2 to reach fixing effect under the effect of spring 713 elastic force toward the direction of spring 713.

The buckle structure of the Pushchair described in above the utility model embodiment, when carrying out deployed condition, operate two road buttons 111, release folds button 112 function, and pressing folds button 112, makes it discharge Telescopic Fixed bayonet lock 113 by bracing wire and is separated with telescopic tube draw-in groove 211, after Telescopic Fixed bayonet lock 113 is separated with telescopic tube draw-in groove 211, handle assembly 1 follows telescopic tube 2 inside down to pass, and clashes into and folds tongue 711, make to fold tongue 711 and be down separated telescopic tube 2; When carrying out collapse state, telescopic tube 2 leaves rear foot assembly 7 with bracket of rear mounting 3 for the strong point, moves to the back-end for point of connection to fold attaching parts 4, in moving process with seating attachment couplings 5 for point of connection drives forward foot in a step assembly 6 to fold toward ride inside.

The above-mentioned description to embodiment can understand and apply this case technology for the ease of those skilled in the art, person skilled in the art obviously can make various amendment to these examples easily, and General Principle described herein is applied in other embodiment and need not through performing creative labour.Therefore, this case is not limited to above embodiment, and those skilled in the art is according to the announcement of this case, and the improvement made for this case and amendment all should in the protection domains of this case.
