The content of the invention
In order to overcome drawbacks described above, the utility model provides a kind of baby carriage back rest folding that can solve the problem that above mentioned problem
Close mechanism.
The utility model in order to solve its technical problem used by technical scheme be：A kind of baby carriage back rest folder
Structure, including backing tube and seat support structure, the backing tube is connected with seat support structure by backrest fixture, described
Backing tube is connected with backing tube B by equivalent backing tube A and formed, and its junction is respectively equipped with equivalent connector A and connector
B, the backing tube A and backing tube B inside are located at one end in backing tube B through a movable locking column, the locking column
The locking stage clip of connection one so that locking column is in backing tube A and backing tube B connection end all the time, and one is provided with the backing tube B
Unlock steel wire, one end connection locking column of the unblock steel wire, on the seat support pipe of other end connecting seat advance expenditure support structure, institute
State seat support structure it is equivalent when, seat support pipe tenses unblock steel wire, and locking column is in the case where unlocking function of wire to backing tube B mono-
Side is moved, and unblock backing tube A completes the equivalent of backing tube simultaneously.
As further improvement of the utility model, the seat support structure include be staggered seat support pipe,
Bench hassock tube and part is slided, described seat support pipe one end is fixedly connected in bench hassock tube one end, and the other end is slided by sliding part and set
It is placed on bench hassock tube.
The beneficial effects of the utility model are：The utility model is additionally arranged equivalent control structure on backing tube, is reaching
While the structure of vehicle frame rigid, vehicle folds while can realizing cushion structure and backrest structure during returning the vehicle to the garage and knock off,
Ride can be made to fold minimum dimension；Small volume, vehicle body are light, outgoing carrying is more convenient, and the whole simple conjunction of Folding structure design
Reason, it is easy to operate, different doll carriage types can be applied to.

Fig. 1-4 shows a kind of a kind of embodiment of baby carriage back rest folding mechanism of the utility model, including backrest
Pipe and seat support structure, the backing tube and seat support structure connected by backrest fixture 11, the backing tube by
Equivalent backing tube A1 connects composition with backing tube B2, and its junction is respectively equipped with equivalent connector A3 and connector B4, institute
Backing tube A1 and backing tube B2 locking column 5 of the inside through an activity is stated, the locking column 5 is located at one end in backing tube B2
The locking stage clip 6 of connection one so that locking column 5 is in backing tube A1 and backing tube B2 connection end all the time, in the backing tube B2
Provided with a unblock steel wire 7, one end connection locking column 5 of the unblock steel wire 7, the seat cushion branch of other end connecting seat advance expenditure support structure
On stay tube 8, when the seat support structure converts into, seat support pipe 8 tenses unblock steel wire 7, and locking column 5 is made in unblock steel wire 7
Moved with lower to backing tube B2 sides, unblock backing tube A1 completes the equivalent of backing tube simultaneously.
Seat support pipe 8 that the seat support structure includes being staggered, bench hassock tube 9 and part 10 is slided, the seat cushion
The one end of support tube 8 is fixedly connected in the one end of bench hassock tube 9, and the other end is slideably positioned on bench hassock tube 9 by sliding part 10.
Whole mechanism folds that process is as follows, and seat support structure is folded in the presence of vehicle, seat support pipe 8
Fold and reduce, as shown in Fig. 2 seat support pipe 8 drives unblock steel wire 7 to tense locking column 5, locking column 5 acts in unblock steel wire 7
The lower Slideslip into backing tube B2, backing tube A1 is left, unlock backing tube A1, now converted into backing tube A1, realize backing tube
It is equivalent, locked conversely, locking column 5 backs into backing tube A1 in the presence of stage clip 6 is locked.
