Description

Technical Field

[0001] The utility model relates to the technical field of children's chairs, in particular to an improved children's chair. Background Art

[0002] A child chair, also known as a child seat, is a seat designed specifically for children. It is usually used in places such as cars, restaurants, schools, and homes to ensure the safety and comfort of children. According to the appearance of the child chair, it can be divided into two types: foldable and non-foldable. For example, in actual use, the folding chair for children (publication number: CN301373183S) has a small appearance and a close distance between the seat and the backrest. When children are playing, they will shuttle between the seat and the backrest, which can easily cause the child's head to get stuck, causing panic in the child's psychology, causing the child to cry and shout, and even causing damage to the child's neck. Therefore, an improved child chair is now provided. Utility Model Content

[0003] The purpose of the utility model is to provide an improved children's chair to solve the problems raised in the above background technology.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] (1) The backrest, leather lining, groove, fixing plate, fixing bolt and fixing screw hole are provided to prevent the head from getting stuck. The backrest is narrow in shape, and the bottom of the backrest is convex in the center and concave on both sides, which effectively increases the distance between the bottom of the backrest and the seat, preventing the head of a child from getting stuck between the leather lining and the seat when playing. At the same time, the center of the bottom of the backrest is convex downward to support the spine. When the backrest area is reduced, the support for the spine is not affected, thereby ensuring safety in use.

[0014] (2) The seat height and stability can be adjusted by providing an extension screw, a foot pad, an adjustment block, a threaded sleeve, a metal ball head, a rubber anti-skid pad and a docking seat. The control adjustment block can drive the extension screw to rotate, and cooperate with the threaded connection with the threaded sleeve to control the extension screw to extend outward, thereby changing the support height of the seat to accommodate children of different heights. In addition, the metal ball head cooperates with the docking seat, and the foot pad can rotate at the bottom end of the metal ball head to adjust the angle of the foot pad, thereby increasing the contact area with the ground and improving the support stability.

[0015] (3) By providing a second fixed axis, a limiting column, a limiting groove, a connecting plate and a third fixed axis, the range of movement of the seat is limited. The flipping of the seat will change the folding state of the connecting plate, indirectly pushing the auxiliary bracket, and the cooperation between the limiting column and the limiting groove can prevent the flipping of the seat and limit the flipping angle of the seat, thereby improving the stability of riding.
