[specific embodiment]
See also shown in Fig. 1-3, the retracting mechanism 1 of the utility model embodiment baby stroller includes:
One folds cliding seat 10, is the hollow penetration state, and both sides are fixing with two side skeletons 20 of baby stroller with a connecting rod 21 respectively, that is folds the two side of cliding seat 10 and the connecting rod 21 of skeleton 20 is connected and fixed.
One assembles seat 11, be build-in in the hollow inner side that folds cliding seat 10, surperficial front end region be separated with saturating empty, both sides, a bottom surface for straight to the fastening plate build-in chamber 110 of wall, rear end region is separated with and one communicates, the bottom is the semicircle inwall folds control knob build-in chamber 111;
One fastening plate 12, be to embed in the fastening plate build-in chamber 110 of assembling seat 11, intermediate lateral is passed an axostylus axostyle 120 and is articulated with fastening plate build-in chamber 110 inwalls, makes fastening plate 12 be the axle center by axostylus axostyle 120, can carry out the seesaw-type upper and lower displacement in fastening plate build-in chamber 110 when being driven.The front end of fastening plate 12 is extended with a clamping hooked 121 downwards, the guide surface 1210 of leading edge tool one pushing and drawing shape of clamping hooked 121.The rear end of fastening plate 12 is connected with clamping hooked 121 strength down that one first pull back spring, 122, the first pull back springs have elasticity pushing tow fastening plate 12.12 outside respectively projections in the both sides in the rear end of fastening plate have a prominent tip 123.
One folds control knob 13 (please cooperate simultaneously and consult Fig. 4,5 and 7), be to embed to assemble 11 folds in the control knob build-in chamber 111, be interior empty shape, side is extended with a control desk 130 and stretches out and assemble seat 11 and fold outside the cliding seat 10, by folding outside the cliding seat 10, can pull control desk 130 controls and fold control knob 13 rotational angles.The inside that folds control knob 13 is to be provided with one second pull back spring 131, one end of second spring 131 is with to fold control knob 13 affixed, the other end is limited fixing by assembly seat 11, fold control knob 13 and driven and rotate an angle and unclasp, second pull back spring 131 can drive and fold control knob 13 and reset.Folding control knob 13 is to embed for fastening plate 12 rear ends towards the inside of fastening plate 12 ends, the inwall both sides respectively have the prominent tip 123 embeddings of an embedded groove that radially is provided with 132 for fastening plate 12, pin is stepped on control desk 130 anglecs of rotation, fold control knob 13 presses fastening plate 12 thereupon rotating the prominent tip 123 down, and compress first pull back spring, making the clamping hooked 121 of fastening plate 12 is that fulcrum raises up with axostylus axostyle 120.And
One is fixed 14 (please cooperate simultaneously and consult Fig. 4,5 and 7) of seat, be to be fixed between 20 of baby stroller two side skeletons and maincenter pipe 22 tops that are parallel to each other with two side skeletons 20, maincenter pipe 22 bottoms and baby stroller chassis articulate, the top extends upward, and is 14 affixed with the seat that is fixed again after penetrating by folding cliding seat 10 bottoms.Be fixed clamping hooked 121 positions of the corresponding fastening plate 12 in seat 14 bottoms have connecting hole 140, and at the baby stroller open configuration, the clamping hooked 121 of fastening plate 12 is can snap in the connecting hole 140, reaches and opens positioning function.The outside wall surface of connecting hole 140 is to guide surface 1210 positions of fastening plate 12, also has to push away the face of catering to 1400 that pulls out accordingly, as the guide surface of clamping hooked 121 with connecting hole 140 buckles.
After above-mentioned member is made up in regular turn, when manipulating:
1. baby stroller will open when location, if with the front and back ends of baby stroller respectively the application of force press down, original position folds cliding seat 10 maincenter pipe 22 lower ends, and is just up sliding along maincenter pipe 22, up to folding till cliding seat 10 runs into the seat 14 that is fixed.Run into and be fixed seat 14 the time when folding cliding seat 10, the clamping hooked 121 of fastening plate 12 is utilized guide surface 1210 and is catered to cooperating of face 1400, seat 14 connecting hole 140 grabs of taking advantage of a situation and be fixed are thus with baby stroller open configuration location (shown in Fig. 4,5,8 and 9).
2. when baby stroller will fold, step on the control desk 130 (shown in Figure 10 and 11) that folds control knob 13, make to fold control knob 13 anglecs of rotation with pin.When folding control knob 13 anglecs of rotation, the prominent tip 123 of interlock fastening plate 12, make fastening plate 12 rear end pressurizeds compress first pull back spring 122 toward bottom offset, fastening plate 12 is that fulcrum causes clamping hooked 121 ends with seesaw-type and raises up with axostylus axostyle 120 just, the connecting hole 140 that clamping hooked 121 raises up just with the seat 14 that is fixed breaks off relations, and so, both hands buttress baby stroller front and back ends down (shown in Fig. 6 and 7), baby stroller can be folded, as shown in figure 12.
By above-listed explanation as can be known, the utility model opens when location at baby stroller, not only clamping hooked 121 and connecting hole 140 grabs, and clamping hooked 121 has the pushing tow of first pull back spring 122 again, make fastening plate 12 and 14 the fastening of seat that is fixed has more certainty, locating effect is good.When baby stroller folds,, baby stroller can be folded, fold tool convenience and easy to operate as long as pin is stepped on the control desk 130 that folds control knob 13.
