For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0025] The present invention will be further described below with reference to the accompanying drawings:

[0026] like Figures 1-7 As shown, a baby stroller push rod locking structure includes a frame 6, a seat 5 on the upper side of the frame 6, a sunshade 4 on the seat 5, a push rod mechanism 2 on the rear side of the frame 6, and also includes a locking mechanism 1 and a locking mechanism 3.

[0027] In this embodiment: the locking mechanism 1 includes a push rod 13, an adjustment button 11 at the upper end of the push rod 13, an unlocking button 12 inside the adjustment button 11, a push seat 14 fixed at the lower end of the push rod 13, a locking plate 15 at the lower end of the push seat 14, a locking cylinder 16 on the outer side of the push seat 14, and a locking seat 17 for sliding support of the locking plate 15 fixed at the lower end of the locking cylinder 16. The lower end of the push seat 14 adopts a wedge-shaped structure, and the locking plate 15 and the wedge-shaped structure of the push seat 14 are respectively provided with inclined surfaces. Press the unlock button 12 to release it from the obstruction of the adjustment button 11, and then press the adjustment button 11 to push the push seat 14 downward through the push rod 13. The wedge structure at the lower end of the push seat 14 pushes the inclined surface of the locking plate 15, thereby causing the locking plate 15 to retract into the locking cylinder 16. At the same time, the spring of the locking plate 15 inside the locking cylinder 16 is compressed, and the locking seat 17 is used to limit the movement of the locking plate 15 to prevent the locking plate 15 from deviating when extending or retracting the locking cylinder 16.

[0028] In the embodiment, the push rod mechanism 2 comprises a sliding push rod 22, the upper end of the sliding push rod 22 is fixed with a handrail 21, the lower end of the sliding push rod 22 is sleeved with a turnover push rod 23, the lower end of the turnover push rod 23 is arranged at the middle position of the rear side of the frame 6, a plurality of lock holes for allowing the locking plate 15 to extend into the lock are formed in the rear side of the turnover push rod 23, the lower end of the sliding push rod 22 is inserted into the upper end of the locking cylinder 16, the locking cylinder 16 is slidingly connected in the turnover push rod 23, the middle position of the top of the handrail 21 is provided with a first hole for allowing the adjusting button 11 to extend out, the rear side of the unlocking button 12 is provided with a second hole for allowing the unlocking button 12 to extend out, the handrail 21 is used to push the whole baby stroller to move, and the sliding push rod 22 is used to slide in the turnover push rod 23, so that the height of the handrail 21 is adjusted, and the pushing is more convenient.

[0029] In the embodiment, the locking mechanism 3 comprises a locking frame 31, the rear side of the locking frame 31 is rotationally connected with a turnover plate 32, the turnover plate 32 and the locking frame 31 are provided with a locking top seat 33, the middle position of the rear side of the locking frame 31 is provided with a locking hole for allowing the locking top seat 33 to abut against the sliding push rod 22, the turnover plate 32 is turned downward to push the locking top seat 33 to extend into the locking hole of the locking frame 31, so that the rear side of the sliding push rod 22 is pressed and locked by the one end of the locking top seat 33 extending into the locking hole, and the sliding of the sliding push rod 22 in the turnover push rod 23 is avoided when the handrail 21 is pushed.

[0030] Working principle: the sliding push rod 22 pushes the turnover push rod 23 by pushing the handrail 21, so that the whole baby stroller starts to move;

[0031] When the height of the handrail 21 needs to be adjusted, the turnover plate 32 is first turned upward to make the turnover plate 32 separate from the pushing of the locking top seat 33, and the locking top seat 33 slides away from the locking hole due to the action of gravity, so that the locking top seat 33 separates from the pressing and locking of the rear side of the sliding push rod 22, and the unlocking process of the first lock is completed;

[0032] Then the unlocking button 12 is pressed to the inside of the handrail 21, so that the unlocking button 12 separates from the blocking of the adjusting button 11, and then the adjusting button 11 is pressed to be shrunk into the inside of the handrail 21, the pushing rod 13 is pushed to slide downward along the inside of the sliding push rod 22 by the downward movement of the adjusting button 11, the pushing seat 14 is pushed to extend into the inside of the locking cylinder 16 by the downward sliding of the pushing rod 13, at this time, the wedge structure at the lower end of the pushing seat 14 pushes the inclined surface of the locking plate 15, so that the locking plate 15 is retracted into the inside of the locking cylinder 16, and the spring in the locking cylinder 16 pushing the locking plate 15 starts to compress, when the one end of the locking plate 15 extending out of the locking cylinder 16 separates from the lock hole of the turnover push rod 23, the whole sliding push rod 22 can drive the locking cylinder 16 to slide in the turnover push rod 23, and the unlocking process of the second lock is completed;

[0033] When the height of the armrest 21 is adjusted properly, the pressed adjusting button 11 is released, at this time the push rod 13 no longer pushes the push seat 14, and the spring in the locking cylinder 16 pushes the locking plate 15 to extend, then the locking plate 15 is inserted into the corresponding lock port after adjustment, at the same time, the inclined surface of the locking plate 15 cooperates with the wedge-shaped structure at the lower end of the push seat 14, so that the push seat 14 pushes the push rod 13 to move upward, then the push rod 13 pushes the adjusting button 11 to extend the armrest 21 upward, then the single heavy locking is completed, then the flap 32 is turned downward, so that the flap 32 pushes the locking top seat 33 to extend into the locking port of the locking frame 31, and the locking top seat 33 extending into the locking port locks the sliding push rod 22.

[0034] The basic principle, main features and advantages of the present application are shown and described above. It should be understood by those skilled in the art that the present application is not limited by the above examples, and the above examples and descriptions in the specification are only to illustrate the principles of the present application. Without departing from the spirit and scope of the present application, various changes and improvements can be made to the present application, and these changes and improvements all fall within the scope of the present application.
