Column 50 is moved to one end in waist hole 22 far from first shaft hole 21, first hook part 23 and the second hook part 32 while clasp
Buckle 41；When needing to unlock and when folding, first sliding shoe 60 is driven to move down, sliding shoe 60 pulls draught line to moving down at this time
It is dynamic, it is rotated counterclockwise in the pulling locking piece 40 of draught line with third shaft 13 for axle center, so that buckle 41 and the first hook
Then portion 23 and the separation of the second hook part 32 rotate counterclockwise the first driving piece 20, the first driving piece at this point, pressure spring is stretched
20 rotate counterclockwise, and driving jack-post 50 moves up, and the jack-post 50 moved in waist hole 22 with after first moving closer to gradually
Far from first shaft hole 21, meanwhile, drive the second driving piece 30 to rotate clockwise, when jack-post 50 is moved to waist hole 22 in waist hole 22
In far from first shaft hole 21 one end when, first driving piece 20 and second driving piece 30 stop movement, fold release joint complete
It folds；When needing to be unfolded and lock, the first driving piece 20 is first driven to rotate clockwise, at this point, jack-post 50 moves down, and
The jack-post 50 moves in waist hole 22 and is gradually distance from first shaft hole 21 afterwards first to move closer to, and drives the first driving piece 20 counterclockwise
Rotation, when jack-post 50 is moved to one end in waist hole 22 far from first shaft hole 21 in waist hole 22, the first driving piece 20 and the
Two driving pieces 30 stop operating, and then, push up sliding shoe 60, draught line is at relaxation state, work of the locking piece 40 in pressure spring
It is rotated clockwise under, buckle 41 clasp the first hook part 23 and the second hook again, to realize locking.
A kind of children trolley of the invention includes above-mentioned folding release joint, is fixed on pushing away on the first driving piece 20
It handle, the front-wheel strut being fixed on the second driving piece 30, the rear wheel fulcrum bar that is fixed on the shell 10 and sets respectively
Set the idler wheel on the front-wheel strut and rear wheel fulcrum bar.
In conclusion above-mentioned folding release joint is compared with prior art, structure is simple, by driving piece 20 first
First hook part 23 and the second hook part 32 are set on the second driving piece 30, by 40 clasp of locking piece, 23 He of the first hook part
Second hook part 32 pulls draught line driving locking piece 40 to realize unlock to be locked, further through sliding shoe 60, consequently facilitating
Operation, and be not in stuck phenomenon.
The above is only a preferred embodiment of the present invention, it is not intended to restrict the invention, it is noted that for this skill
For the those of ordinary skill in art field, without departing from the technical principles of the invention, can also make it is several improvement and
Modification, these improvements and modifications also should be regarded as protection scope of the present invention.
