Free to rotate between part and the second rod piece, when the two relatively rotates, one end of lock pin 12 is slideably against the second rod piece
On, it will not influence relative rotation between the two, and when the two turns to a certain relative position, lock pin 12 is in the second elastic component
Under the action of 14, one end is connect across avoiding structure with sliding block 10 and tripper locking.
As shown in attached drawing 1, attached drawing 4 and attached drawing 7-8, this gives a kind of specific structure of folding children's cart,
The top of the fore-stock 22, rear portion and the fore-stock 22 that are movably connected including push rod, with push rod rotates the handrail of connection
23, after-poppet 25, top and the fore-stock 22 of connection of rotating with push rod rotates connection and lower part and after-poppet 25 rotates
The support rod 26 of connection, the bottom of fore-stock 22 and the bottom of after-poppet 25 are respectively connected with wheel 20.Push rod is the first rod piece, preceding
Bracket 22 is the second rod piece, and handrail 23 is third rod piece, and after folding children's cart folds, folding children's cart is with respect to fore-stock 22
Downslide is mutually drawn close with fore-stock 22 and after-poppet 25.The folding children's cart has above-mentioned tripper.
Specifically, above-mentioned push rod includes that upper push-rod 24, top and upper push-rod 24 rotate the lower push-rod 21 of connection, under push away
Bar 21 is movably connected with fore-stock 22.The lower part of lower push-rod 21 in the present embodiment has the L shape portion bent backwards
211, the top of after-poppet 25 rotates with the L shape portion 211 and connect.According to above-mentioned folding children's cart structure, above-mentioned
One rod piece is lower push-rod 21, and the 4th rod piece is upper push-rod 24.Above-mentioned tripper is provided at left and right sides of cart.
Illustrate the working principle of this tripper by taking the structure of above-mentioned folding children's cart as an example:
When Folding trolley, forward downward rotates upper push-rod 24, draws close the downward push rod 21 of upper push-rod 24, passes through hauling rope
10 upward sliding of sliding block inside lower push-rod 21 is driven, for sliding block 10 in upward sliding, the first inclined-plane 101 pushes rotary buckle
11 rotations, make latch hook 111 be detached from the locked groove 15 on plastic cement pedestal 221, thus make to unlock between lower push-rod 21 and fore-stock 22, with
This simultaneously, third inclined-plane 103 pushes lock pin 12 mobile, so that lock pin 12 is exited the groove on sliding block 10, to make handrail 23 under
It is unlocked between push rod 21；After tripper unlock, lower push-rod 21 is pushed down on, and rotated down lower push-rod 21 and upper push-rod backward
24, lower push-rod 21 is moved down along fore-stock 22, and lower push-rod 21, upper push-rod 24, fore-stock 23 and support rod 26 are to after-poppet
25 draw close, and handrail 23 can be rotated by self gravity or be drawn close by manual rotation operation to fore-stock 22, until all
Rod piece is drawn close completely completes vehicle folding.When opening cart, with above-mentioned steps on the contrary, each rod piece relative motion and opposite exhibition
Open, when lower push-rod 21 be moved upward to latch hook 111 it is corresponding with 15 position of locked groove on plastic cement pedestal 221 when, first elasticity
Under the action of part 13,10 slide downward of sliding block, the second inclined-plane 102 pushes rotary buckle 11 to rotate, and makes latch hook 111 and 15 phase of locked groove
Connection, will lock between lower push-rod 21 and fore-stock 22, and at the same time, lock pin 12 is corresponding with the groove location on sliding block 10,
Under the action of the second elastic component 14, lock pin 12 is mobile and is inserted into groove, and handrail 23 is locked.
A kind of tripper of folding children's cart of the utility model drives rotary buckle and lock pin to move simultaneously by sliding block
Make, so that two groups of rod pieces be enable to unlock simultaneously, is applied in folding children's cart, then it can be while unlocking vehicle frame
By handrail or other a certain rod piece unlocks, folding step is simplified, it is easy to operate.
The above embodiments are only for explaining the technical ideas and features of the present invention, and its object is to allow be familiar with technique
Personage can understand the content of the utility model and implement accordingly, do not limit the protection scope of the present invention.
All equivalent change or modifications according to made by the spirit of the present invention essence, should all cover the protection scope of the utility model it
It is interior.
