The second driving member 92 is provided with a first hook 921, the third driving member 93 is provided with a second hook 932, and the first hook 921 and the second hook 932 are clamped and matched, so that the second driving member 92 and the third driving member 93 can synchronously slide and can relatively rotate.
When the child dining chair is in the use state, the first locking mechanism and the second locking mechanism are both in the locking state, and the child seat pocket 2 can be located at the low-grade position on the dining chair frame as required, i.e. the first locking portion 51 of the first locking member 5 is inserted into the first locking groove 131 located below the seat plate 13, as shown in fig. 20, 22 and 23. Child seat pocket 2 can be in the top-grade position on the dining chair frame as required, i.e. first locking portion 51 of first locking member 5 is inserted into first locking groove 131 above seat plate 13, as shown in fig. 21, 26 and 27.
When the child seat pocket 2 is switched between the high-gear position and the low-gear position, the second unlocking button 91 is pressed to slide upwards relative to the seat portion 21, the second driving member 92 is pulled to slide leftwards or rightwards relative to the seat portion 22 and towards the outside direction of the child dining chair through the second traction cable 94, and the third driving member 93 is driven to slide relative to the adjusting member 3 along the same direction; the first locking piece 5 rotates around the second shaft 42 relative to the adjusting piece 3 through the matching or movable connection of the third driving piece 93 and the first locking piece 5; so that the first locking part 51 is disengaged from the first locking slot 131, the first locking mechanism is unlocked, and the adjusting member 3 can drive the child seat pocket 2 to slide up and down relative to the dining chair frame to adjust the position, as shown in fig. 24 and 25. During unlocking of the first locking mechanism, both the first elastic member 81 and the second elastic member 82 are compressed and charged with energy. After adjusting part 3 drives children's seat pocket 2 and slides to required position department, loosen second unblock button 91, the elastic force of first elastic component 81 orders about second unblock button 91 and slides downwards and resets, the elastic force of second elastic component 82 orders about first locking piece 5 antiport and resets, thereby make first locking part 51 can insert once more and establish in another first locking groove 131, first locking mechanical system locks once more, thereby realize children's seat pocket 2 and change between high gear position and low gear position.
When the child seat pocket 2 needs to rotate the adjustment position in the horizontal plane, the operation portion 62 of the second locking member 6 is operated to slide the second locking member 6 backward relative to the child seat pocket 2 until the second locking portion 61 is disengaged from the second locking groove 32, the second locking mechanism is unlocked, and the child seat pocket 2 can rotate the adjustment position in the horizontal plane around the first shaft 41 relative to the adjustment member 3, as shown in fig. 31 and 32. During the process of unlocking the second locking mechanism, the third elastic member 83 is compressed and charged. When the operating part 62 of the second locking member 6 is released, the elastic force of the third elastic member 83 drives the second locking member 6 to slide forward and return until the second locking part 62 is inserted into the other second locking groove 32, the second locking mechanism is locked again, and the child seat pocket 2 is rotated and adjusted to a corresponding position, as shown in fig. 29 to 30.
The above embodiments are only for illustrating the technical concept and features of the present invention, and the purpose of the embodiments is to enable people skilled in the art to understand the contents of the present invention and to implement the present invention, which cannot limit the protection scope of the present invention. All equivalent changes and modifications made according to the spirit of the present invention should be covered by the protection scope of the present invention.
