[0002] As the name implies, a baby carriage is a "means of transportation" for infants and children to ride in. By placing the baby in the carriage, it is convenient for adults to take the baby out without having to hold the baby all the time, reducing the burden on adults when going out. Most common baby carriages are foldable, which makes it convenient to fold and carry the baby carriage. Therefore, in order to enable the various skeletons of the baby carriage to form a folding fit, movable connecting components are generally used for connection and locking, so that the skeletons can be connected to each other and the folding operation of the entire baby carriage will not be hindered.

[0003] However, the common connection locking mechanisms for baby carriage skeletons generally only have a movable function. After the skeletons are folded and contracted, this movable function is not blocked by an external force, resulting in the baby carriage being easily opened, affecting the folding effect and causing certain trouble for people when carrying it out.

[0004] Therefore, it is necessary to provide a new skeleton connection locking mechanism for a baby carriage to solve the above technical problems. Summary of the Utility Model

[0023] The working principle of the skeleton connection locking mechanism of the baby carriage provided by the present utility model is as follows:

[0024] In the use state, the circular skeleton 1 and the flat skeleton 6 are in a vertical state;

[0025] When the flat frame 6 needs to be folded and stored, first rotate the first stud 12 to take the locking head 13 out of the locking hole 7, then rotate the second stud 19 to take the positioning head 20 out of the corresponding first positioning groove 16. Subsequently, rotate the flat frame 6. After rotating the flat frame 6 by 90°, first rotate the driving shaft 14, which drives the driving toothless gear 15 to rotate. At this time, by using the meshing between the driving toothless gear 15 and the driven toothless gear 9, the connecting piece 10 can be driven to rotate. After the connecting piece 10 rotates by 90°, the locking head 13 corresponds to the locking hole 7 again. Then rotate the first stud 12 to bring the locking head 13 into the locking hole 7. At this time, the positioning head 20 corresponds to the second positioning groove 17. Immediately rotate the second stud 19 to bring the positioning head 20 into the second positioning groove 17. At this time, the folding work is completed, and the flat frame 6 and the circular frame 1 are in a parallel state.
