In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, however, the present invention may be practiced in other ways than those specifically described herein, and therefore the present invention is not limited to the limitations of the specific embodiments of the present disclosure.

Embodiment 1, as shown in fig. 1 to 7, this embodiment aims to provide a lifting armrest for a child chair, which has a wide application range and is convenient for a child to operate, and for this reason, the lifting armrest for a child chair provided in this embodiment includes an armrest seat 1 disposed in an L shape, and the armrest seat 1 is designed in an L shape, and is mainly convenient to mount on a learning chair without a lifting armrest, and for this reason, the armrest seat 1 includes a mounting portion 11 horizontally fixed at the bottom of the seat plate and an adjusting portion 12 vertically disposed at one side of the seat plate, the mounting portion 11 is disposed in a flat plate shape as a whole, and bolt holes are disposed on the mounting portion 11, so as to be conveniently fixed with the seat plate.

The main effect of regulating part 12 is exactly to realize the regulation of height, and for this reason, is equipped with lift post 2 at regulating part 12 overcoat, and like this, regulating part 12 and lift post 2 have just constituted the structural design of telescopic link, and in this embodiment, regulating part 12 is square design, and for this reason, lift post 2 also is square setting. The top of the lifting column 2 is provided with a handrail 3, and the handrail 3 is used for supporting the arms of the child and blocking the body of the child.

In order to realize the rapid and labor-saving lifting adjustment of the lifting column 2 relative to the adjusting portion 12, in this embodiment, an elastic component 4 is disposed in the adjusting portion 12, the lifting column 2 is arranged in the adjusting portion 12 in a lifting manner through the elastic component 4, specifically, the adjusting portion 12 is disposed in a hollow manner, adjusting grooves 13 are disposed on two side surfaces of the adjusting portion 12 in a longitudinal direction, trapezoidal teeth 14 are disposed on side walls of the adjusting grooves 13 at intervals, the trapezoidal teeth 14 are disposed in the longitudinal direction, the elastic component 4 includes an elastic ring 41 disposed in the adjusting portion 12, the elastic ring 41 is made of an elastic material, such as plastic, a connecting block 42 is disposed at one end of the elastic ring 41, the connecting block 42 is disposed at a middle position on one side of the elastic ring 41, the connecting block 42 is disposed in a rectangular parallelepiped shape, pin columns 43 are disposed on two sides of the connecting block 42, in this embodiment, for convenience of installation, holes are disposed on the connecting block 42, the pin 43 is provided with a through hole so that the pin 43 can be disposed in the adjustment groove 13 by inserting the elastic ring 41 and the connection block 42 into the intermediate cavity of the adjustment part 12 and then passing the pin 43 through the adjustment groove 13.

In the present embodiment, the key posts 44 are disposed through the elastic ring 41, the connecting block 42, the adjusting portion 12 and the lifting post 2, the adjusting portion 12 is provided with a longitudinal groove 15 for the key posts 44 to move up and down, and the front and rear ends of the lifting post 2 are provided with through holes 21 for the key posts 44 to pass through. Because the elastic ring 41 and the connecting block 42 are both arranged in the adjusting part 12, when the key column 44 is pressed inwards from the through hole 21 of the lifting column 2, the connecting block 42 moves backwards to press the elastic ring 41, so that the pin column 43 is positioned on one side of the adjusting groove 13 away from the trapezoidal teeth 14, and meanwhile, the key column 44 extends out from the through hole 21 at the other end of the lifting column 2, so that the lifting column 2 is convenient to adjust, when the lifting column 2 is adjusted to a proper height, the key column 44 is loosened by a hand, and under the counter-acting force of the elastic ring 41, the pin column 43 is pushed between the two trapezoidal teeth 14, so that the lifting column 2 is relatively fixed, the whole structure is simple, and the control operation of children is convenient.

For convenience of processing and use, the elastic ring is arranged in an oval shape. Of course, in the present embodiment, the oval is similar to an ellipse, and may have other shapes.

In order to ensure the stability of the structural elastic assembly 4, any one of the longitudinal grooves 15 of the adjustment portion 12 is a longitudinal arc-shaped tooth groove 16. In this embodiment, the longitudinal slot 15 on the side away from the trapezoidal tooth 14 is a longitudinal arc-shaped slot 16, so that the longitudinal arc-shaped slot 16 also plays a certain supporting role for the key post 44, and the structural stability is ensured.

In order to facilitate the children to leave, in the embodiment, the armrest handle 3 and the lifting column 2 can be arranged in a turnover mode. The arrangement of the turnover structure can be the arrangement of the existing commonly used structure, and can also be the corresponding structure provided in the embodiment, specifically, a left connecting circle 22 and a right connecting circle 23 are respectively arranged on the left side and the right side of the top of the lifting column 2, a groove arc through hole 24 is arranged on the left connecting circle 22 and the right connecting circle 23, a connecting hole is arranged in the middle of the left connecting circle 22 and the right connecting circle 23, the groove arc through hole 24 is arranged on one side of the connecting hole, a column 31 matched with the left connecting circle 22 and the right connecting circle 23 is arranged below the rear end of the armrest handle 3, a rotating shaft hole is arranged in the center of the column 31, a rotating shaft 32 is arranged in the rotating shaft hole, the rotating shaft 32 can also be a bolt which is mainly used for realizing the connection between the two, the rotating shaft 32 extends into the connecting hole of the left connecting circle 22 and the right connecting circle 23, a positioning shaft 33 used for extending into the groove arc through hole 24 is also arranged on the column 31, thus, the rotation distance of the positioning column is only as large as the radian of the groove arc-shaped through hole 24, so that the handrail handle 3 can realize the limiting overturning relative to the lifting column 2 through the limiting of the positioning shaft 33. In the present embodiment, to realize the 90 ° turn, the armrest handle 3 can be horizontally and vertically disposed.
