Specific embodiment
Above scheme is described further below in conjunction with specific embodiment.It should be understood that these embodiments are for illustrating
The utility model and be not limited to limitation the scope of the utility model.Implementation condition used in the examples can be according to specific
Condition do further adjustment, the implementation condition being not specified is usually the condition in routine experiment.
As shown in Figures 1 to 7, the front-wheel control structure of a kind of stroller, including vehicle frame 1 and it is separately mounted to vehicle frame
The front component 2 and wheel assembly 3 of the 1 forward and backward side in lower section, 2 top of front component has the vertical shaft for assembling with vehicle frame 1
Mounting base 1-2 is equipped at component 2-1, the handle 1-1 of the vehicle frame 1, the mounting base 1-2 is equipped with can be rotatable relative
Operation handlebar 4,1 front of vehicle frame have with vertical shaft component 2-1 locking cooperation front-wheel retaining mechanism 5, the mounting base 1-2 with
The front-wheel clutch for clutch control that can release the opposition shaft assembly 2-1 locking of front-wheel retaining mechanism 5 is respectively equipped between front-wheel retaining mechanism 5
Mechanism 6 and the front-wheel steer regulating mechanism 7 that 2 left-right rotation of front component can be driven；Interlinked mechanism is equipped in the mounting base 1-2
8, which has two kinds of working conditions of front-wheel clutch state and front-wheel steer adjustment state, before interlinked mechanism 8 is in
When taking turns clutch state, interlinked mechanism 8 drives the opposition of front-wheel retaining mechanism 5 shaft assembly 2-1 to release by front-wheel clutch control mechanism 6
Front-wheel universal rotational is realized in locking；When interlinked mechanism 8 is in front-wheel steer adjustment state, interlinked mechanism 8 make operation handlebar 4 with
7 phase of front-wheel steer regulating mechanism interlocks, and drives 2 left-right rotation of front component by rotation operation handlebar 4；And the interlinked mechanism 8 exists
Conversion between front-wheel clutch state and front-wheel steer adjustment state realizes operation control by aforesaid operations.
In the present embodiment, the interlinked mechanism 8 and the specific structure of operation handlebar 4 and the assembly relation of the two are as follows: the company
Motivation structure 8 include connect with front-wheel steer regulating mechanism 7 cooperation connector 8-1, be arranged in connector 8-1 and opposite can connect
The sliding block 8-2 of fitting 8-1 sliding, it is arranged in sliding block 8-2 and connector 8-1
Between the first spring 8-3 and the card slot 4-1 that is arranged on operation handlebar 4 and is caught in for sliding block 8-2, it is described
