The avoiding groove 23 is arc-shaped, and the center of the arc is on the axis of the rotating shaft 4. As for the above-described second locking mechanism, a structure in the related art may be adopted, and since it is not the focus of the present invention, the structure thereof will not be described in detail here.
Operation process and theory of operation when folding children's seat pocket is opened in this embodiment:
the backrest 2 is rotated upwards to be far away from the seat board 1, the elastic lug boss 8 is limited in the limiting groove 70, so that the armrest 3 is driven to rotate together with the backrest 2 and is unfolded relative to the seat board 1, when the armrest 3 and the backrest 2 rotate and are unfolded to a certain angle, the locking hole 32 on the armrest 3 corresponds to the locking piece 5, the locking piece 5 is inserted into the locking hole 32 under the action of the elastic piece 6, and the position of the armrest 3 is locked. The backrest 2 is rotated continuously, the armrest 3 is locked and cannot rotate continuously any more, the force for rotating the backrest 2 is increased, the elastic boss 8 is elastically deformed under the action of force to be separated from the limiting groove 70, and passes through the isolating part 72 and enters the movable groove 71, the backrest 2 can rotate normally continuously, and when the backrest 2 rotates to the preset position, the second locking mechanism locks the backrest 2. So far folding children seat pocket is accomplished and is opened, the seat pocket can also carry out angle modulation in the open position, and is not because of angle modulation the utility model discloses a key, do not do detailed description consequently.
Example two
Referring to fig. 10 and 12, the foldable baby seat pocket of the present embodiment is different from the first embodiment only in that: the elastic boss 8 is provided on the backrest 2, and the stopper groove 70, the slide groove 71, and the spacer 72 are provided on the armrest 3. The method specifically comprises the following steps: the stopper groove 70 and the sliding groove 71 are formed along the edge of the handle connecting portion 31 in a recessed manner, and the elastic projection 8 is formed by the groove wall of the groove 22 protruding toward the center of the groove 22. The operation process and the working principle of the folding child seat pocket in the first embodiment when the folding child seat pocket is opened are the same as those in the first embodiment, and therefore the description is omitted.
The folding children seat pocket in the above-mentioned embodiment, when opening, through the conflict of elasticity boss and spacing groove, makes the handrail can rotate along with the back together to realize the automation of handrail and open, need not the independent operation handrail and open. When the armrest rotates to the set position, the locking mechanism locks the armrest, the backrest can continue to rotate, and the elastic lug boss slides into the sliding groove from the limiting groove and slides along the sliding groove until the backrest rotates to the set position. This folding children's seat pocket has realized opening in step of back and handrail through a set of mechanism, has simplified the opening operation step to simple structure, manufacturing cost is lower.
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.
