The technical scheme of
the utility model is: a kind of self-support supporting mechanism of doll carriage; Comprise the rear wheel support that front-wheel support, upper end and push rod bottom that push rod, upper end and push rod bottom are rotationally connected are rotationally connected, and the seat cushion bar, the front end of said seat cushion bar is connected with the front-wheel support pin joint; The rear portion is connected with the rear wheel support pin joint; Said rear wheel support lower end is connected with the feet that extends forward, is connected with the spike connecting strap between said seat cushion bar rear portion and the feet, when the go-cart vehicle frame folding; Front-wheel support and rear wheel support draw in; Rotate to the front lower place at seat cushion bar rear portion, and the spike connecting strap drives the front portion of feet and rotates to the back lower place, feet is cooperated with the trailing wheel of rear wheel support and realizes that automatic the standing of car load establish.
are further; Said feet is opening U type backward; Its both ends respectively with the left and right pole pin joint of rear wheel support; Said spike connecting strap is two, its respectively pin joint in the both sides of U type feet near the position of end and seat cushion bar between the both sides at position, rear wheel support rear.
The utility model has the advantages that:
1. the utility model when vehicle frame folding; Rotate to the back lower place front portion that is driven feet by seat cushion bar and spike connecting strap; Feet is cooperated with the trailing wheel of rear wheel support and realize that car load is automatically upright and establish; Make doll carriage after folding all can stand and establishes that not only floor area is less but also have stability preferably anywhere, vehicle frame falls down and hurts sb.'s feelings when having avoided mistake to bump.
. the feet of the utility model is opening U type backward; And be respectively equipped with a spike connecting strap between both sides and the seat cushion bar; So not only guaranteed the reliability that feet is opened automatically downwards in the vehicle frame folding process; And feet and ground-surface area of contact have been increased, the stability when having improved upright the establishing of folding back vehicle frame.

wherein: 1 push rod; 2 front-wheel supports; 3 rear wheel supports; 4 seat cushion bars; 5 feets; 6 spike connecting straps; 7 trailing wheels; 8 two roads lock button; 9 handle knob; 10 first rivets; 11 second rivets; 12 the 3rd rivets; 13 the 4th rivets; 14 the 5th rivets.
The specific embodiment
embodiment: to shown in Figure 4, a kind of self-support supporting mechanism of doll carriage comprises the rear wheel support 3 that front-wheel support 2, upper end and push rod 1 bottom that push rod 1, upper end and push rod 1 bottom are rotationally connected are rotationally connected like Fig. 1; And seat cushion bar 4, the front end of said seat cushion bar 4 is connected with front-wheel support 2 pin joints, and the rear portion is connected with rear wheel support 3 pin joints; Said rear wheel support 3 lower ends are connected with the feet 5 that extends forward; Be connected with spike connecting strap 6 between said seat cushion bar 4 rear portions and the feet 5, when the go-cart vehicle frame folding, front-wheel support 2 draws in rear wheel support 3; Rotate to the front lower place at seat cushion bar 4 rear portions; Spike connecting strap 6 drives the front portion of feets 5 and rotates to the back lower place, feet 5 is cooperated with the trailing wheel 7 of rear wheel support 3 and realizes that car load stands automatically and establishes that the doll carriage after feasible the folding all can stand to be established anywhere; Not only floor area is less but also have preferably stability, and vehicle frame falls down and hurts sb.'s feelings when having avoided mistake to bump.
are further; Said feet 5 is opening U type backward; Its both ends respectively with the left and right pole pin joint of rear wheel support 3; Said spike connecting strap 6 is two, its respectively pin joint in the both sides of U type feet 5 near the position of end and seat cushion bar 4 between the both sides at position, rear wheel support 3 rear.So not only guaranteed the reliability that feet 5 is opened automatically downwards in the vehicle frame folding process, and increased feet and ground-surface area of contact, the stability when having improved upright the establishing of folding back vehicle frame.
When the utility model was implemented, the concrete motion process of each parts was following:
During
vehicle frame folding, stressed when pinning on the push rod 1 two roads lock button 8 in handling knob 9, make the vehicle frame release; At this moment; Push rod 1 is applied one to the power F1 that presses down, make vehicle frame shrink by 13 4 points of the 4th rivet between the 3rd rivet 12, push rod and the rear wheel support between second rivet 11, push rod and the front-wheel support between first rivet 10, seat cushion bar and the front-wheel support between seat cushion bar and the rear wheel support; As shown in Figure 3, seat cushion bar 4 rotatablely moves around first rivet 10, second rivet 11 in the folding process of returning the vehicle to the garage and knock off, and is connected the effect that spike connecting strap 6 on the seat cushion bar 4 receives the power F2 that seat cushion bar 4 moves downward this moment; Feet 5 when rotating to the certain displacement amount, makes vehicle frame to obtain the function of supporting oneself through the additional forces of feet 5 being that centre of gration rotates to the back lower place with the 5th rivet 14 between feet 5 and the rear wheel support 3 under the effect of power F2.
When
vehicle frame launches, on push rod 1, apply a power F3 who upwards carries; At this moment, vehicle frame launches by first rivet 10, second rivet 11, the 3rd rivet 12,13 4 points of the 4th rivet; Be connected spike connecting strap 6 on the seat cushion bar 4 and receive the effect of the power F4 of seat cushion bar 4 upward movements; Feet 5 is that centre of gration shrinks to the front upper place with the 5th rivet 14 under the effect of tensile force f 4, and when vehicle frame launched fully, feet 5 was retracted to position shown in Figure 1.
Only be the concrete exemplary applications of the utility model more than
, the protection domain of the utility model is not constituted any limitation.Except that the foregoing description, the utility model can also have other embodiment.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop within the utility model scope required for protection.
