Description
Technical field
The utility model relates to a kind of children trolley.
Background technology
In the prior art, children trolley generally by the sidecar frame of both sides, be arranged at the sidecar frame below of both sides front-wheel and trailing wheel, be arranged at stop member between the sidecar frame of both sides etc. and form.Each side stand comprises front-wheel support, rear wheel support, push rod, thereby rotating setting makes vehicle frame to fold between front-wheel support, rear wheel support and the push rod usually, and the both sides of stop member removably are connected with the side stand of each side respectively, when children trolley uses, side stand is launched, and stop member is linked to each other with the side stand vehicle frame; In the time need not using, stop member is pulled down from side stand, thereby children trolley can be folded into smaller volume.But constantly carry out the loading and unloading of stop member, troublesome poeration, time-consuming, and the often consume of loading and unloading meeting quickening stop member.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of children trolley, and the folding volume of this children trolley is little, folding operation convenient.
For solving above technical matters, the utility model is taked following technical scheme:
A kind of children trolley, comprise go-cart vehicle frame with expanded position and folding position, be arranged at the front-wheel of front portion at the bottom of the go-cart vehicle frame, be arranged on the trailing wheel at rear portion at the bottom of the go-cart vehicle frame, be used for the go-cart vehicle frame is locked in the lockout mechanism of expanded position, the go-cart vehicle frame comprises the side stand that is positioned at both sides, be arranged at many cross bars between the side stand of both sides, be used to the stop member that prevents that children from falling from the go-cart vehicle frame, the both sides of described stop member rotate with each described side stand respectively and are connected, and the go-cart vehicle frame also is included in forbids first stop gear that stop member rotates when the go-cart vehicle frame is in expanded position.
Each described side stand comprises pulling handle rod, stop member is provided with mutually rotationally with pulling handle rod, first stop gear comprises first limiting stopper on that is arranged in pulling handle rod and two parts of stop member, when the go-cart vehicle frame is in expanded position, first limiting stopper is resisted against on another parts, when the go-cart vehicle frame was in the folding position, first limiting stopper and another parts were separated.
Be fixedly connected with Connection Block on the bottom of pulling handle rod, the both sides of stop member are arranged on respectively on the described Connection Block of each side rotationally, are provided with at Connection Block to protrude on the side of stop member first limiting stopper is set.
Described side stand also comprises the bottom of upper end and the pulling handle rod bonded assembly connecting rod that rotates, and is provided with second stop gear of forbidding that when the go-cart vehicle frame is in expanded position stop member upwards rotates between connecting rod and the stop member.
Described second stop gear comprises second limiting stopper on that is arranged in connecting rod and two parts of stop member, when the go-cart vehicle frame is in expanded position, second limiting stopper is resisted against on another parts, when the go-cart vehicle frame was in the folding position, second limiting stopper and another parts were separated.
Described side stand comprises that also leading section is rotatably mounted with the front-wheel support of front-wheel, is rotatably mounted with the rear wheel support of trailing wheel in the bottom, the upper end of rear wheel support rotates with the bottom of pulling handle rod and is connected, the rearward end of front-wheel support rotates with rear wheel support and is connected, and constitutes four-bar linkage between pulling handle rod, connecting rod, front-wheel support and the rear wheel support.
The sidepiece of the upper end of described connecting rod and the rotational axis line of Connection Block, stop member and the rotational axis line of described Connection Block coincide.
Because the enforcement of above technical scheme, the utility model compared with prior art has following advantage:
Because stop member is and the side stand bonded assembly that rotates, the go-cart vehicle frame is in when organizing work state, and stop member is in stable expanded position by the effect of first stop gear; When the go-cart vehicle frame is folded, the spacing releasing of first stop gear, stop member opposite side support can rotate and folding, guarantee that children trolley has less folding volume, when this children trolley is folded, need not the loading and unloading of stop member, easy to operate.

The specific embodiment
The utility model is described in more detail below in conjunction with accompanying drawing and concrete embodiment:
Extremely shown in Figure 7 as Fig. 1, children trolley according to present embodiment is a kind of child's tricycle, it mainly comprises side stand 1, front-wheel 2, the trailing wheel 3 of both sides and is arranged on stop member 4 between the side stand 1 of both sides, wherein stop member 4 both can be used to place article, can also strengthen children's safety as children's handrail simultaneously.
The both sides of stop member 4 rotate with the Connection Block 14 of each side respectively and are connected, make when 12 pairs of side stands 1 of promotion pulling handle rod fold, stop member 4 also can the folding along with the folding of side stand 1, thereby reduce the volume of folding back go-cart, simultaneously in order to guarantee when children trolley is in expanded position, stop member 4 can be firm be in expanded position, also be provided with first stop gear and second stop gear on the children trolley, first stop gear mainly comprises and protrudes first limiting stopper 5 be arranged on the Connection Block 14 on the side of stop member 4, when children trolley is in expanded position, first limiting stopper 5 is positioned at the below of stop member 4, and the bottom of stop member 4 is resisted against on first limiting stopper 5, first limiting stopper 5 can stop stop member 4 downward foldings, guarantees that stop member 4 is in stable expanded position; Second stop gear comprises second limiting stopper 6 that is arranged on the connecting rod 13, and when children trolley was in the folding position, second limiting stopper 6 also leant with stop member 4, prevents that stop member 4 from upwards rotating.
In sum, relative rotatable between the stop member of the children trolley of present embodiment and the described side stand, therefore need not it is pulled down the folding volume that can realize that children trolley is less.The lockout mechanism of this children trolley is mainly to comprise first limiting stopper that is fixed on the side stand, when go-cart launches, barrier effect by first limiting stopper guarantees that stop member is in the expanded position on steady top, and when go-cart is folded, because pulling handle rod is folding forward, first limiting stopper breaks away from stop member automatically, the lockout mechanism automatic unlocking, thereby folding when realizing stop member and side stand, guarantee that children trolley has less folding volume.
