In the presence of power, the top of the same neck of its excircle part is stuck on the positive stop lug boss in upper joint, and bottom is stuck in hypozygal
Positive stop lug boss on so that upper joint and hypozygal can not relatively rotate.
Need that perambulator return the vehicle to the garage and knock off operation when, it is only necessary to pull bracing wire, bracing wire is driven sliding part along drawing bracing wire side
To motion, because the inclined plane of the inclined plane of the wedge of driving member first the second wedge corresponding with sliding part coordinates, therefore
Driving member can be axially moved under the promotion of sliding part perpendicular to the direction of motion motion of sliding part along center column, so as to
Spline gear is promoted to overcome the elastic force of spring to be moved to hypozygal side, until the cylindrical neck of spline gear and the limit in upper joint
Position boss departs from.Once the cylindrical neck of spline gear departs from the positive stop lug boss in upper joint, upper joint is then no longer influenced by spline
The limitation of gear, now upper joint and hypozygal can relatively rotate, operation is folded to perambulator so as to realize.
And now, the positive stop lug boss in upper joint and hypozygal misplaces, therefore the positive stop lug boss of upper joint can not be caught in spline tooth
Take turns in cylindrical neck.
When carrying out expansion operation, then only need to rotate upper joint or hypozygal, until in upper joint and hypozygal
Positive stop lug boss is just relative, and now spline gear can upwards move and block the positive stop lug boss of upper joint under the action of the spring,
So as to which the mechanism be locked.
Preferred embodiment of the present utility model is these are only, is not limited to the utility model, for this area
Technical staff for, the utility model can have various modifications and variations.It is all within the spirit and principles of the utility model,
Any modification, equivalent substitution and improvements made etc., should be included within the scope of protection of the utility model.
