Three components of chassis in, two of them component rotatedly connects, and third component rotatedly connects with one in two
It connects, the rear pole mutually slides with the fore-stock and is rotatedly arranged.
Stroller seat part disclosed above cannot link with vehicle frame and fold, after needing first to fold seat,
Folding stand can be given, is operated relatively cumbersome.
Utility model content
The utility model discloses the children trolleys that a kind of seat can interlock folding, solve existing cart seat and need elder generation
Vehicle frame folding, cumbersome problem.
A kind of seat can interlock the children trolley of folding, including handle stem and seat bar, and the handle stem includes rotation connection
Upper hand handle and lower hand handle, the first sliding part with the rotation connection of seat bar, first sliding part are provided in the lower hand handle
It is provided with the first seat link with both rotation connection between upper hand handle, is provided between the seat bar and lower hand handle
With the second seat connecting rod of both rotation connection, when folding, it is close that the upper hand handle around tie point rotates downward hand handle, together
When drive the first sliding part mobile by the first seat link so that seat bar rotates downward hand handle and draws close.
The sliding part can be sliding sleeve or sliding block, and sliding part is slided along handle stem when sliding, and sliding sleeve is relatively easily real
It is existing, it is directly set in hand handle, when selecting sliding block, needs to be arranged on handle stem sliding rail, structure is relative complex.
Preferably, the tie point of the upper hand handle and lower hand handle is higher than the connection of the upper hand handle and the first seat link
The front of point, the second seat connecting rod and seat bar is rotatablely connected, and under the structure, when upper handle rotation, the first seat link is drawn
Dynamic first sliding part upward sliding, second seat connecting rod and seat bar angulation are increasing, gradually tend on the same line,
And hand handle is drawn close downwards.
Preferably, in cart unfolded state, on the same line, frame shape is more beautiful for the upper hand handle and lower hand handle
It sees.
It is furthermore preferred that the bottom of the upper hand handle has the quarter butt for connecting lower hand handle, the top of the lower hand handle has curved
Trisection.
Preferably, the children trolley includes the chassis for being equipped with wheel, the bottom of the handle stem and the front of chassis
Rotation connection, is provided with strut between the chassis and handle stem.
It is furthermore preferred that the strut bottom end and chassis are rotatablely connected, the second sliding part on top and handle stem, which rotates, to be connected
It connects.
Preferably, the posterior rotation of the seat bar is connected with backrest.
On the utility model when the downward handle rotation of hand handle, can be driven by the first seat link the first sliding part along
Lower hand handle sliding, so that drive seat bar is rotated around with the tie point of the first sliding part, downward hand handle is drawn close, and realizes linkage folding
It is folded, it is easy to operate.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model children trolley unfolded state.
Fig. 2 is the structural schematic diagram of the utility model children trolley intermediate state.
Fig. 3 is the structural schematic diagram of the utility model children trolley folded state.
Specific embodiment
As shown in Figure 1, a kind of children trolley, including inclined handle stem 1 and chassis 7, bottom and the chassis 7 of handle stem 1
Front rotation connection, be additionally provided with strut 8 between the two, the bottom end of strut 8 and chassis 7 are rotatablely connected, top and handle stem 1
On sliding sleeve 9 be rotatablely connected.Handle stem 1 and strut 8 are two be arranged symmetrically under normal circumstances, and chassis 7 has and hand handle
Bar 1 is in conplane bottom bar 70, and cross bar (not shown) is provided between two bottom bars 70, increases the intensity of chassis 7.Bottom
The both ends of bar 70 are separately installed with front-wheel 71 and rear-wheel 72, and 72 diameter of rear-wheel is greater than the diameter of front-wheel 71 in the present embodiment.
Basket, which is set, often to be set between handle stem 1 and chassis 7, due to the shape of the utility model frame substantially " > "
Shape, so it is more convenient to pick and place article.Cart is used in order to one hand, two symmetrical 1 tops of handle stem can dock to form U
The middle part of the handle (not shown) of type, U-shaped handle can be with locking releasing mechanism.The another embodiment of the utility model is two
The bottom of handle stem 1 also docks and forms U-shaped structure, and the middle part of U-shaped structure and chassis 7 are rotatablely connected, and does not influence to use.
In order to prevent cart from folding in the deployed state, strut 8, handle stem are provided between handle stem 1 and chassis 7
There is the locking pin (not shown) of fixed sliding sleeve 9, sliding sleeve can not move when locking, strut 8, handle stem 1 and chassis 7 on 1
Constitute stable triangle.When locking pin exits lock hole, sliding sleeve 9 can be moved along handle stem 1, and the triangle can be with
Deformation occurs, and cart can fold.It is clear that sliding sleeve 9 also can be set on bottom bar 70, identical effect also may be implemented
Fruit.
The handle stem 1 of the utility model folds rod structure, is made of the upper hand handle 11 and lower hand handle 12 that are rotatablely connected, two hands
The seat assembly being made of seat bar 3 and backrest 6 is provided between barre 1, wherein the posterior rotation of the bottom of backrest 6 and seat bar 3
Connection can be arranged cloth set when use on seat assembly, constitute seat.The cunning being rotatablely connected with seat bar 3 is provided in lower hand handle 12
Set 5, sliding sleeve 5 connect upper hand handle 11 by seat link 2, the both ends of seat link 2 bottom end with sliding sleeve 5 and upper hand handle 11 respectively
Rotation connection.The seat link 4 with both rotation connection is provided between the front of seat post 3 and lower hand handle 12.When upper
When hand handle 11 is rotated around tie point 14, seat link 2 pulls sliding sleeve 5 along lower 12 upward sliding of hand handle, so that seat bar 3 is sent out
Raw rotation, downward hand handle 12 are close.
It will be seen from figure 1 that connection of the tie point 14 of upper hand handle 11 and lower hand handle 12 than upper hand handle 11 and seat link 2
Point is high, therefore when the rotation of upper hand handle 11, it drives seat link 2 to haul 5 upward sliding of sliding sleeve, if upper hand handle 11 and set about
Tie point 14 12 is lower with the tie point of seat link 2 than upper hand handle 11, and upper hand handle 11 will drive seat link 2 to push cunning
Set 5 moves down, and so needs seat link 4 and the posterior rotation of seat bar 3 to connect, it is possible to can have certain interference.
For good appearance, in vehicle frame unfolded state, upper hand handle 11 and lower hand handle 12 are on same straight line, certain seat
Connecting rod 2 also may be on same straight line, be only in different planes.There is quarter butt in the upper hand handle 11 of the utility model
13, the end of quarter butt 13 and lower hand handle 12 are rotatablely connected, and the top of corresponding lower hand handle 12 has bending segment.
It is provided at some angle for the triangle that upper hand handle 11, lower hand handle 12 and seat link 2 are constituted in the utility model
Locking mechanism, for example locking mechanism is set at tie point 14, when the locking mechanism release the lock, upper hand handle 11 can be around the connection
Point 14 rotates, and vehicle frame can be folded.The locking pin of locking sliding sleeve 5 can certainly be set in lower hand handle 12, it should
The locking pin of locking pin and locking sliding sleeve 9, which interlocks, to be arranged, so that it may realize that a step unlocks.
