Description
Technical field
The utility model relates to a kind of children trolley.
Background technology
A kind of children trolley of the prior art is accepted by increasing family, can be with children trolley usually when travelling outdoors, can be for infant sitting, to alleviate caregiver's burden when children trolley is opened.Children trolley can fold reducing volume, and some children trolley all is on all fours after folding in the prior art, and floor area is bigger.And in the industry, the folding back of children trolley floor area is less to be the target that the designer pursues always.
The utility model content
The technical problems to be solved in the utility model provides the less children trolley of a kind of folding back floor area.
For achieving the above object, the technical solution adopted in the utility model is: a kind of children trolley, comprise go-cart vehicle frame with open position and folding position, front component, wheel assembly, be arranged on the lockout mechanism that is used for described go-cart vehicle frame is locked in open position on the described go-cart vehicle frame, described go-cart vehicle frame comprises first side stand that lays respectively at both sides, second side stand, be connected in the link span between described first side stand and described second side stand, described link span can be can be laterally folded and make the relative link span of drawing close with second side stand of the side stand of winning, and promptly children trolley can be laterally folded; Also can be the many cross bars that two ends are fixedly connected with the corresponding site of first side stand and second side stand respectively, this structure makes the side stand of winning can not draw close relatively with second side stand, and promptly children trolley can not be laterally folded,
Described first side stand comprises the upper end of first front-wheel support, bottom and described first front-wheel support rotate bonded assembly first push rod, first rear wheel support;
Described second side stand comprises the upper end of second front-wheel support, bottom and described second front-wheel support rotate bonded assembly second push rod, second rear wheel support;
The upper end of described first rear wheel support is connected rotatedly with the top of described first front-wheel support, and described first side stand also comprises
First bar, the front portion of described first bar is connected rotatedly with described first front-wheel support;
First boxed rod, the upper end of described first boxed rod is connected rotatedly with the bottom of described first push rod, the bottom of described first boxed rod is connected rotatedly with the rear portion of described first bar, and described first push rod, described first front-wheel support, described first bar and described first boxed rod constitute four-bar linkage;
First lower link, the upper end of described first lower link is connected rotatedly with described first bar, the bottom of described first lower link is connected rotatedly with described first rear wheel support, and described first front-wheel support, described first bar, described first lower link and described first rear wheel support constitute four-bar linkage;
The upper end of described second rear wheel support is connected rotatedly with the top of described second front-wheel support, and described second side stand also comprises
Second bar, the front portion of described second bar is connected rotatedly with described second front-wheel support;
Second boxed rod, the upper end of described second boxed rod is connected rotatedly with the bottom of described second push rod, the bottom of described second boxed rod is connected rotatedly with the rear portion of described second bar, and described second push rod, described second front-wheel support, described second bar and described second boxed rod constitute four-bar linkage;
