End, the upper end of right rear foot tube are articulated with the 6th pin joint E.
First front fork tube and the second front fork tube it is arranged in a crossed manner and crosspoint rotate connect, first front fork tube it is upper
End is articulated with the 5th pin joint, and the lower end of first front fork tube, which is articulated with the bottom of the right front foot pipe, (is designated as the
Seven pin joint F), the upper end of second front fork tube is articulated with the 6th pin joint, and the lower end of second front fork tube is articulated with institute
State on the bottom of left front foot tube and (be designated as the 8th pin joint G).
First back breeches pipe and the second back breeches pipe it is arranged in a crossed manner and crosspoint rotate connect, first back breeches pipe it is upper
End is articulated with the second pin joint of the left connector, and the lower end of first back breeches pipe is articulated with the bottom of the right rear foot tube
On, the upper end of second back breeches pipe is articulated with the 4th pin joint of the right connector, and the lower end of second back breeches pipe is articulated with
On the bottom of the left back foot tube.
The left front foot tube and right front foot pipe lower end are respectively equipped with front component 17, the left back foot tube and right rear foot tube
End is respectively equipped with wheel assembly 18.
The expansion, which folds support component, includes lock 141, compression spring 142 and pin 143, a left side for the horizontal support pipe
End and right part are connected by pin rotation, and the left part upper side of the horizontal support pipe extends laterally to form lateral projection
131 are used to stop that the right part of the horizontal support pipe is rotated up with respect to the left part of the horizontal support pipe, the lock and compression
Spring is movably set in the pin outside one end of the horizontal support pipe successively, and the lock is under the horizontal support pipe
Side surface direction extends the right part to form oblique hook 1411 for horizontal support pipe described in buckle, and the compression spring is springy to be pushed against
In the lock.
The top and bottom of first front fork tube pass through corner strap connector 19 and the 5th pin joint and the right side respectively
The bottom of front foot pipe is hinged, and the top and bottom of second front fork tube pass through corner strap connector 19 and the described 6th respectively
The bottom of pin joint and left front foot tube is hinged；The top and bottom of first back breeches pipe pass through corner strap connector 19 respectively
It is hinged with the second pin joint of the left connector and the bottom of right rear foot tube, the lower end point of the upper end of second back breeches pipe
It is not hinged by corner strap connector 19 with the 4th pin joint of the right connector and the bottom of left back foot tube.
The upper end of the left and right push rod, which is respectively equipped between handle jacket 20, the left and right push rod, is provided with secondary fuse group
Part 21.
The children trolley side plane by tetra- pin joints of A, B, C, D formation quadric chains, opposite side similarly so that real
The expansion of existing side plane and closing function.
The transverse plane of the children trolley set front cross pipe be respectively hinged at by 90 degree of corner straps forward and backward foot tube A,
On 4 points of E, F, G, during deploying and folding, AE/FG distance diminish/become it is big, so as to reach the exhibition of stroller transverse plane
Open and closing function, the function of its rear cross pipe is similarly.
Therefore, the children trolley releases the secondary fuse component between left and right push rod, then released first when folding
Expansion on horizontal support pipe folds the lock-out state of support component, the left and right end of horizontal support pipe is realized that folding is folded.
Then pull left and right push rod and be rotated down and folded, when folding, behind left front foot tube, left back foot tube and right front foot pipe and the right side
Foot tube respectively draw in by longitudinal direction, while the first front fork tube and the second front fork tube and the first back breeches pipe and the second back breeches pipe are also indulged simultaneously
To gathering, so as to realize the children trolley and fold.
Wherein, expansion folds support component in lock-out state, and left part, right part and the lock of horizontal support pipe lead to together
The pressure of overcompression spring pushes down lock, the oblique hook of lock bottom is hooked the right part of horizontal support pipe, so that horizontal support now
The right part of pipe is rotated down, the upper side of the left part of horizontal support pipe provided with lateral projection stop the right part of horizontal support pipe to
Upper rotation, so that forming one stablizes firm entirety.When folding is folded, firmly lock is outwards pulled, makes oblique hook portion
Depart from the right part of horizontal support pipe, so as to the rotation for the right part for realizing horizontal support pipe.When children trolley is opened, horizontal branch
The right part of stay tube is oppressed oblique hook and is displaced outwardly, and turns to the left part horizontal level with horizontal support pipe, latches in compression spring
In the presence of automatically reset pin horizontal support pipe right part.
As can be seen here, the light stroller of the children trolley relatively on the market has the horizontal folding function that it does not possess, can be with
Realize folding for ride side plane and transverse plane, and it is equivalent after front and back wheel side by side closely, front and back wheel lands self-support,
Therefore, the storage small volume (particularly short transverse reduces about 30CM than traditional umbrella car) of the children trolley, while after folding
It also may move, be easy to carry and collect.Meanwhile, the children trolley is that push rod converts into backward, and existing children trolley (can laterally convert into
Stroller) push rod be forward upset or slide downward, broken receipts and the side of traditional stroller (stroller that can laterally convert into)
Formula.In addition, the children trolley is set is respectively formed firm gusseted framework between forward and backward breeches pipe and push rod, front/back foot tube support,
Structure is more stable and firm during open mode.In addition, the angle between the backrest and seat of the children trolley can reach most preferably
170 degree of sleeping position angles, this is also the kinetic energy not available for traditional umbrella car.In a word, the children trolley possesses light stroller
Lightly, and traditional umbrella car horizontal folding function, and broken the equivalent mode of traditional umbrella car reach self-support store, space
Small, high landscape, the function that can be lain low.
