When the rear baffle 2 is completely unfolded relative to the handrail frame 3, the protrusion 21 is located at one end of the track groove 32, and when the rear baffle 2 is completely folded relative to the handrail frame 3, the protrusion 21 moves to the other end of the track groove 32. By setting the track groove 32 and the protrusion 21 matched with the track groove 32, the position of the rear baffle 2 can be effectively limited.

[0037] Preferably, the two ends of the track groove 32 are respectively formed with a positioning groove 33 matched with the positioning of the protrusion 21. When the rear baffle 2 is completely folded and unfolded relative to the handrail frame 3, the protrusion 21 will move into the corresponding positioning groove 33, thereby positioning the rear baffle 2. In the embodiment, the rear baffle 2 is made of plastic, and when it is necessary to adjust the relative position of the rear baffle 2 and the handrail frame 3, the rear baffle 2 only needs to be bent, so that the protrusion 21 is separated from the corresponding positioning groove 33.

[0038] In the embodiment, referring to Figure 1 , Figure 2 , Figure 3 and Figure 5As shown, the front end of the handrail frame 3 is provided with a front baffle 11, the front baffle 11 extends horizontally along the front end of the handrail frame 3, the front baffle 11 is detachably inserted and matched with the handrail frame 3, a plurality of gear holes 111 are arranged on the front baffle 11 along the direction of insertion and matching with the handrail frame 3, the handrail frame 3 is provided with a gear block 34 corresponding to the gear holes 111, by arranging the gear block 34 and the gear holes 111, the relative position of the handrail frame 3 and the front baffle 11 can be adjusted, so as to meet the needs of users. In the folded state, the rear baffle 2, the handrail frame 3 and the front baffle 11 correspond to be located on the same plane. When the folding type children's product provided by the utility model is used as a children's dining chair or a children's booster seat, the front baffle 11 can be used as a dinner plate. When the folding type children's product provided by the utility model is used as a children's ladder stool, the front baffle 11 can be used as a front guard plate.

[0039] In the embodiment, referring to Figure 6 As shown, the seat plate 1 is provided with a locking mechanism in cooperation with the front support 4, the locking mechanism can lock the relative position of the seat plate 1 and the front support 4 at least when the children's product body is unfolded. Preferably, the locking mechanism comprises a sliding block 121, a spring 122, a locking pin 123, an upper locking hole 124 and a lower locking hole 125, the seat plate 1 is provided with a sliding groove 126, the sliding block 121 is slidingly arranged in the sliding groove 126, the spring 122 is arranged between the seat plate 1 and the sliding block 121, the locking pin 123 is fixedly connected with the sliding block 121, the upper locking hole 124 and the lower locking hole 125 are arranged on the inner side of the front support 4 and correspondingly arranged with the locking pin 123, and the seat plate 1 is further provided with an unlocking handle 127, the unlocking handle 127 is connected to the sliding block 121 through a pull rope (not shown in the figure).

[0040] Preferably, the seat plate 1 is provided with a connecting sleeve 13, the upper end of the rear support 5 and the lower end of the sliding sleeve 9 are hingedly connected with the seat plate 1 through the connecting sleeve 13, and the locking pin 123 is slidingly arranged in the connecting sleeve 13. The rear support 5 and the sliding sleeve 9 are hingedly connected with the seat plate 1 through the connecting sleeve 13, the coaxial hinged structure design not only makes the unfolding / folding operation more flexible, but also is more conducive to assembly, in addition, the locking pin 123 is slidingly inserted into the connecting sleeve 13, which not only saves the installation space, but also effectively improves the position accuracy of the locking pin 123 by using the connecting sleeve 13.

[0041] When the child product body is in the fully unfolded state, the locking pin 123 is inserted into the lower locking hole 125 of the front support 4 under the action of the spring 122, the relative position of the seat plate 1 and the front support 4 is locked by the cooperation of the locking pin 123 and the lower locking hole 125, at this time, the child product body is in the unfolded and locked state; when folding is needed, the unlocking handle 127 is pulled, the unlocking handle 127 pulls the sliding block 121 through the pull rope, the sliding block 121 drives the locking pin 123 to move out of the lower locking hole 125 by overcoming the elastic force of the spring 122, the seat plate 1 and the front support 4 are in the unlocked state, at this time, the driving sliding sleeve 9 moves upward along the front support 4, and the child product body can be folded. When the child product body is completely folded, the pin shaft is aligned with the upper locking hole 124 of the front support 4, at this time, the spring 122 will push the pin shaft into the upper locking hole 124 through the sliding block 121, so that the child product body is in the folded and locked state.

[0042] The above is only the preferred embodiment of the present application, therefore, equivalent changes or modifications made according to the structure, features and principles described in the patent application range of the present application are included in the patent application range of the present application.
