Specific implementation mode
The technical solution of the utility model is further elaborated in the following with reference to the drawings and specific embodiments.
The locking mechanism of the utility model is arranged between the stroller frame 10 and vehicle wheel component 20 of children trolley, wheel group
Part 20 includes the wheel 22 taken turns connector 21 and be arranged on wheel connector 21, and wheel connector 21 is rotatably arranged in stroller frame 10
On, the locking mechanism of the utility model is used to take turns the relative position locking between connector 21 and stroller frame 10, the locking machine
Structure has locking and unlocked state, when locking mechanism is in the lock state, takes turns the position between connector 21 and stroller frame 10
It is relatively fixed, when locking mechanism is in the unlocked state, wheel connector 21 can be rotated with motor car wheel 22 relative to stroller frame 10.
Shown in referring to Fig. 1 and Fig. 2, which includes the locking pin 1 that can be slidably arranged in stroller frame 10
With the lockhole 2 being arranged on wheel connector 21, when locking mechanism is in the lock state, locking pin 1 is plugged in lockhole 2, works as lock
Determine mechanism it is in the unlocked state when, locking pin 1 is deviate from from lockhole 2.
Stroller frame 10 has expansion and folded state, when stroller frame 10 is in unfolded state in use, the locking machine
Structure is in the lock state, and when stroller frame 10 folds, can drive locking mechanism automatic unlocking, which further includes working as to push away
Vehicle carriage 10 drives the solution lock set of locking mechanism automatic unlocking, solution lock set when folding include that can be slidably arranged in cart
Actuator 31 and one end on vehicle frame 10 are fixed at the hauling rope 32 on actuator 31, actuator 31 and 1 phase of locking pin
Cooperation, when stroller frame 10 folds, makes hauling rope 32 be tightened up, and hauling rope 32 pulls actuator 31 sliding in stroller frame 10
It is dynamic, drive locking pin 1 also to be slided in stroller frame 10 by the cooperation of actuator 31 and locking pin 1, up to locking pin 1 is from lock
Deviate from hole 2, locking mechanism is just in the unlocked state.
The locking mechanism further includes the return unit 4 for driving locking pin 1 to be resetted from unlocked state to lock-out state, is resetted
