Preferably, described two gears in the present embodiment are respectively the first gear 110 and the second gear 120, the first gears 110 are fixedly connected with front foot rest 21, and the second gear 120 is fixedly connected with pushing hands frame 22; Described gear system comprises two intermeshing the 3rd gears 130 and the 4th gear 140; The first gear 110 is meshed with the 3rd gear 130, and the second gear 120 is meshed with the 4th gear 140; Described gear system is arranged to two gears that are meshed, makes the first gear 110 and the second gear 120 and its engagement rotation; The more suitable inside rotation of forward foot in a step frame 21 and pushing hands frame 22 is drawn in.

Further, in lock box 10, the top that is positioned at described two gears and gear system also is provided with the spanner 150 that folds moving up and down; The bottom that folds spanner 150 is provided with the engagement section, is provided with the lower engagement section that can be fixed togather with described upper engagement section on described two gears; As shown in Figure 1, described fold also be provided with on the spanner can with described fold spanner upwards lift mobile and make that described upper engagement section and described lower engagement section break away from mutually lift attacker 151, be provided with on the box wall of lock box 10 to make and lift the lifting opening 11 that attacker 151 is exposed;

Preferably, described upper engagement section is the locating piece to lower convexity; The positioning groove of described lower engagement section for matching with described locating piece;

Further, as shown in the figure 3 and shown in Figure 4, the described upper engagement section in the present embodiment is the blocks of projection, comprises the first locating piece 152 and the second locating piece 153; The groove of described lower engagement section for matching with described blocks comprises the first positioning groove 111 and the second positioning groove 121; The first positioning groove 111 is arranged on the first gear 110, and near the joint between the first gear 110 and the front foot rest 21, the second positioning groove 121 is arranged on the second gear 120, and near the joint between the second gear 120 and the pushing hands frame 22.

Buckle into hand and to lift attacker 151, and upwards lift and fold spanner 150, make and fold spanner 150 relative lock boxes 10 and move up, just make the first locating piece 152 and the second locating piece 153 respectively from the first positioning groove 111 and the 121 interior disengagings of the second positioning groove, also just make the first gear 110 and the second gear 120 untie the location, continue upwards to lift perambulator, just make under the Action of Gravity Field of front foot rest 21 and pushing hands frame 22, rotate with the second gear around the first gear 110 respectively and draw close, fold and be in the same place, as shown in Figure 5, the hand of rotation schematic diagram of each gear when folding perambulator.

Preferably, as shown in Figure 2, the attacker 151 that lifts in the present embodiment is used for the portable cell body close to rectangle, is convenient to people's manual manipulation.

As shown in Figure 3 and Figure 4, the top of the lock box in the present embodiment 10 be provided with can move back and forth fold the lock 160; The top that folds lock 160 is exposed at the outside of lock box 10, and the bottom is the inside that is positioned at lock box 10; The top that folds spanner 150 is provided with separates the lock section; Folding lock 160 top is lock knob 161, and the bottom is for can be by fastening or be separated to control and fold the tight lock part that spanner 150 moves up and down with the described spanner solution lock section that folds;

Preferably, the described tight lock part that folds lock in the present embodiment is a lock dog 162 to lower convexity; Lock dog 162 is positioned to push away turns round 161 bottom; The described lock dog groove 154 of solution lock section for matching with described lock dog that folds spanner; The position of lock dog 162 is relative with the position of lock dog groove 154 or be staggered moving back and forth of lock box 10 tops with it;

When lock dog 162 and lock dog groove 154 are staggeredly located, fold distance between the crowning of spanner 150 and lock dog 162 less than the distance that engages between the lower engagement section on the upper engagement section and described two gears that fold on the spanner 150, described two gears are maintained the lock status; When lock dog 162 is relative with lock dog groove 154 positions, fold displacement that made lock dog 162 that spanner 150 moves up matches with lock dog groove 154 greater than the distance that engages between the lower engagement section on the upper engagement section and described two gears that fold on the spanner 150, make described two gears be in rotatable released state.

Further, lock dog 162 is cuboid, the rectangular channel of lock dog groove 154 for matching with cuboid lock dog 162, when lock dog 162 is positioned at the outside of lock dog groove 154 and is staggered with it, the first locating piece 152 and the second locating piece 153 fold insufficient space that spanner 150 moves up so that, therefore can guarantee the first gear 110 and the second gear 120 fully from the first positioning groove 111 and the 121 interior disengagings of the second positioning groove is locked by actv.;

Further, during locking state, lock dog 162 is positioned at the outside of lock dog groove 154, and withstand and fold spanner 150, make and fold spanner 150 and can't in lock box 10, make progress mobile, therefore the first gear 110 and the second gear 120 are maintained the lock status, can not rotate, make perambulator remain on the use state of expansion; After promoting forward lock knob 161 and making lock dog 162 and described lock dog groove 154 relative, just make and fold spanner 150 and possessed enough spaces that moves up, thereby can fold the release that spanner is realized the first gear 110 and the second gear 120 by lifting, and then can make forward foot in a step frame 21 and pushing hands frame 22 inwardly rotation collapse to be folded and be in the same place, as shown in Figure 6, be the stereoscopic-state schematic diagram of perambulator after folding, wherein a side is in order to show better the structure of lock box 10 inside, and do not show seat lock 40.

Should be noted that at last obviously, those skilled in the art can carry out various changes and modification to the utility model and not break away from spirit and scope of the present utility model.Like this, if these are revised and modification belongs within the scope of the utility model claim and equivalent technologies thereof, then the utility model also is intended to comprise these changes and modification.
