Description

Technical Field

[0001] The utility model relates to the technical field of infant stools, in particular to an ergonomic stool that is convenient for infants to use. Background Art

[0002] Young children spend most of their time sitting on benches in the classroom to listen to lectures and learn, so benches are particularly important tools for young children's learning. High-quality benches can cultivate children's correct sitting posture, reduce children's fatigue in class, and enable children to concentrate faster in class and learn knowledge more easily. However, most of the children's teaching benches on the market are fixed benches with simple structures. Because children have different heights, they are prone to develop bad sitting habits when using them. For this reason, we propose an ergonomic bench that is easy for young children to use.

[0011] Beneficial Effects

[0012] The utility model provides an ergonomic stool that is convenient for children to use and has the following beneficial effects:

[0013] (1) The ergonomic stool, which is convenient for young children to use, can adjust the height of the seat plate by swinging between two swing legs. The swing angles of the two swing rods can be synchronously adjusted by the swing block. The swing angle between the two swing legs can be controlled by controlling the swing angle of the two swing rods, so that the swing amplitude between the two swing legs remains stable. The position of the swing block is fixed by a locking structure to further lock the position of the swing leg. On the basis of the adjustability, the stability of use is maintained, thereby adjusting the height of the seat plate, making it convenient for young children of different heights to use, and preventing young children from developing bad sitting habits due to the stool being too high or too low.

[0014] (2) The ergonomic stool that is convenient for young children to use has two locking threaded cylinders that squeeze the upper and lower ends of the swing block on the threaded rod to fix the swing block, and then the swing legs are locked by locking threaded columns to perform a secondary locking operation, thereby improving stability during use.
