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 9, the front-wheel control structure of a kind of perambulator, including vehicle frame 1 and be separately mounted under vehicle frame 1
The front component 2 and wheel assembly 3 of the forward and backward side in side, 2 top of front component have the vertical shaft group for assembling with vehicle frame 1
Mounting base 1-2 is equipped at part 2-1, the handle 1-1 of the vehicle frame 1, the mounting base 1-2 is equipped with operation that can be rotatable relative
4,1 front of vehicle frame has the front-wheel retaining mechanism 5 with vertical shaft component 2-1 locking cooperation, the mounting base 1-2 and front-wheel
The front-wheel clutch control mechanism 6 that can release the opposition shaft assembly 2-1 locking of front-wheel retaining mechanism 5 is respectively equipped between retaining mechanism 5
With the front-wheel steer regulating mechanism 7 that can drive 2 left-right rotation of front component；Interlinked mechanism 8 is equipped in the mounting base 1-2, it should
Interlinked mechanism 8 have two kinds of working conditions of front-wheel clutch state and front-wheel steer adjustment state, when interlinked mechanism 8 be in front-wheel from
When conjunction state, interlinked mechanism 8 drives the opposition of front-wheel retaining mechanism 5 shaft assembly 2-1 to release lock by front-wheel clutch control mechanism 6
Tightly, front-wheel universal rotational is realized；When interlinked mechanism 8 is in front-wheel steer adjustment state, interlinked mechanism 8 makes operation handlebar 4 with before
It rotates and is interlocked to 7 phase of regulating mechanism, 2 left-right rotation of front component is driven by rotation operation handlebar 4；And the interlinked mechanism 8 is preceding
The conversion taken turns between 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, the first spring 8-3 being arranged between sliding block 8-2 and connector 8-1 and setting are being grasped
Make the card slot 4-1 being caught on 4 and for sliding block 8-2, the sliding block 8-2 are had projection portion 8-2-1, on the connector 8-1
There is the guide groove 8-1-1, the card slot 4-1 that are slidably matched with projection portion 8-2-1 to have limit corresponding with projection portion 8-2-1 in portion
Position portion 4-1-1；On the operation handlebar 4 have depressible button 4-2, the inner end of the button 4-2 protrude into card slot 4-1 and with cunning
Block 8-2 is matched.
Aforesaid operations turn the 4 control interlinked mechanisms 8 between front-wheel clutch state and front-wheel steer adjustment state
The working principle changed is as follows:
