Description

Technical Field

[0001] The utility model relates to the technical field of folding chairs, in particular to a folding chair with a telescopic function. Background Art

[0002] A chair is a seat with a backrest and some have armrests. In ancient times, people sat on the ground and there were no chairs originally. "Chair" was originally the name of a wood. The name of chair first appeared in the Tang Dynasty, and the image of chair can be traced back to the Hu bed that was introduced to the north during the Han and Wei dynasties. Chairs are classified according to their use: children's chairs, office chairs, dining chairs, etc. Among them, children's chairs are seats designed for children. They are very common in kindergartens and families with children. In order to facilitate transportation and storage, the chair frame is usually connected by a multi-rod frame to form a folding connecting rod mechanism, so that it can be converted between the unfolded position and the folded position.

[0003] Since children grow faster, the length of the chair pedal cannot be changed according to the child's body shape, which makes the folding chair less applicable. When in use, the folding chair does not have good flexibility, and the angle of the chair back may not conform to the current child's body shape, which brings a bad use experience to the child. The child seats sold on the market either have armrests but are not foldable, which is inconvenient to carry, or are foldable but do not have armrests, which is not very safe for children to sit on. Therefore, in order to solve the above problems, the utility model proposes a folding chair with a telescopic function. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a folding chair with a telescopic function. The exposed length of the telescopic plate can be adjusted by pushing an adjusting button so that the pedal can adapt to children of different sizes, thereby effectively improving the applicability of the folding chair. The armrests are used to provide protection for children to prevent them from tipping over due to their activeness. The angle of the chair back can be adjusted by pressing a button at the bottom of the adjusting box, and the height of the chair seat can be adjusted by cooperating with the sliding blocks on the supporting legs, thereby improving the flexibility of the folding chair.

[0005] The utility model provides the following technical solution: a folding chair with a telescopic function, comprising a seat, a pedal movably connected to the front of the seat through an axis, a telescopic plate movably sleeved on the bottom of the pedal, holes evenly opened on the right of the pedal, three holes in number, an adjusting button movably sleeved in the hole, a folding arm movably connected to the rear of the seat through an axis, two folding arms in number and symmetrically distributed on the left and right, an armrest movably connected to the front of the folding arm through an axis, a tray fixedly installed on the front of the armrest, and a chair back movably connected to the rear of the seat and located between the two folding arms through an axis.

[0006] Preferably, an adjustment box is fixedly mounted on the top of the back of the chair, a button is movably sleeved on the bottom of the adjustment box, a transmission rope is provided on the back of the chair, and the upper end of the transmission rope is fixedly connected to the adjustment box.

[0007] Preferably, the left and right parts of the seat are movably connected to support legs one through an axis, the top end of the support leg one is movably connected to the folding arm and the armrest through an axis, and the upper part of the support leg one is movably sleeved with adjustment button two.

[0008] Preferably, a moving block is fixedly sleeved at the middle of the supporting leg one, a sleeve block is movably connected to the rear of the moving block via an axis, and a section of the sleeve block away from the moving block is fixedly sleeved at the supporting leg two.

[0009] Preferably, a connecting plate is fixedly installed between the two supporting legs 1 and 2.

[0010] Compared with the prior art, the utility model has the following beneficial effects:

[0011] 1. The position of the telescopic plate can be adjusted by pushing the adjustment button in the hole, so that the telescopic plate can be extended and retracted at the bottom of the pedal, thereby adjusting the exposed length of the telescopic plate, so that the pedal can adapt to children of different sizes, avoiding the need to replace the folding chair according to children of different sizes, so that the applicability of the folding chair is effectively improved. At the same time, by setting the armrest, it can be folded and the armrest can be used to provide protection for children, preventing the folding chair from tipping over due to children's activeness.

[0012] 2. By pressing the button at the bottom of the adjustment box, the transmission rope pulls the chair back to adjust the angle, which makes it convenient for the folding chair to be flexibly adjusted to meet the needs of different children. The height of the seat can be adjusted by adjusting the position of the moving block on the supporting leg, so that the folding chair can be adjusted in height, which improves the flexibility of the folding chair and allows manufacturers to reduce the production of different models of folding chairs and reduce the consumption of production resources. Compared with traditional non-adjustable folding chairs, it can effectively improve children's use experience. BRIEF DESCRIPTION OF THE DRAWINGS
