Description

Technical Field

[0001] This utility model belongs to the field of office equipment technology, specifically relating to a training folding chair. Background Technology

[0002] Folding chairs are needed in current educational activities, but existing folding chairs have many components, making assembly and production cumbersome. Therefore, it is very important to obtain a foldable training chair with fewer components. Utility Model Content

[0003] To solve at least one of the above-mentioned technical problems, this utility model provides a training folding chair, including a seat surface, a first rod connected to opposite sides of the seat surface via a first hinge shaft, and a second rod connected to the opposite inner sides of the two first rods via a second hinge shaft. The bottom of the seat surface is provided with a plurality of slots that cooperate with the second rods.

[0004] A chair back is fixed between the top of the first rod located above the first hinge shaft. An installation groove is provided on the chair back, and a placement plate is connected to the installation groove through a third hinge shaft.

[0005] The above technical solution allows the placement board, seat, backrest, and second rod to rotate, thus enabling folding.

[0006] As a preferred embodiment, a support groove is formed on the first rod, and a third rod is connected to the support groove via a second hinge shaft. An insertion slot is formed on the back of the placement plate to mate with the end of the third rod. The third rod is shorter than the length of the support groove, so that when the third rod is rotated, a finger can be inserted into the gap formed between the end of the third rod and the inner wall of the support groove.

[0007] Through the above technical solution, the third rod can support the placement plate and increase the stability of the support.

[0008] As a preferred embodiment, both ends of the first hinge shaft and the second hinge shaft are threaded with nuts that fit tightly together to form a damping structure.

[0009] Through the above technical solution, the damping structure can achieve limiting in the folded state.

[0010] As a preferred embodiment, a limiting ring is fixed to the outside of the third hinge shaft, and the surfaces of the chair back and the support plate are made of plastic so that they can generate electrostatic adsorption when they are closed.

[0011] As a preferred embodiment, magnetic components and adsorption materials, both in sheet form, are installed between the connecting surfaces of the chair back and the support plate to achieve positioning when folded.

[0012] Through the above technical solutions, electrostatic adsorption or magnetic adsorption can achieve the limitation of the folded state.

[0013] As a preferred embodiment, the bottom of the first and second rods is fixed with several silicone anti-slip pads to increase the stability of the support.

[0014] Compared with the prior art, the advantages of this utility model are: the utility model has a simple structure, fewer parts, and can be folded. Attached Figure Description

[0021] To enable those skilled in the art to better understand this utility model and to more clearly define the scope of protection claimed by this utility model, the present utility model is described in detail below with reference to certain specific embodiments. It should be noted that the following are only some specific embodiments of the present utility model concept, and are only a part of the embodiments of this utility model. The specific and direct description of related structures is only for the convenience of understanding this utility model, and the specific features do not necessarily or directly limit the scope of implementation of this utility model.

[0022] Referring to the accompanying drawings, the present invention adopts the following technical solution: the present invention provides a training folding chair, including a seat 1, first rods 3 connected to opposite sides of the seat 1 via a first hinge shaft 2, and second rods 5 connected to the opposite inner sides of the two first rods 3 via a second hinge shaft 4. The bottom of the seat 1 is provided with a plurality of slots that cooperate with the second rods 5; the slots are structurally consistent with the insertion slots 12 provided on the placement plate 9.

[0023] A chair back 6 is fixed between the top of the first rod 3 located on the upper part of the first hinge shaft 2. An installation groove 7 is provided on the chair back 6, and a placement plate 9 is connected to the installation groove 7 through the third hinge shaft 8.

[0024] Through the above technical solution, the placement plate 9, the seat 1, the backrest 6 and the second rod 5 can rotate to achieve folding.

[0025] As a preferred embodiment, the first rod 3 has a support groove 10, and a third rod 11 is connected to the support groove 10 via a second hinge shaft 4. The back of the placement plate 9 has an insertion groove 12 that mates with the end of the third rod 11. The third rod 11 is shorter than the length of the support groove 10, so that when the third rod 11 is rotated, a finger can be inserted into the gap 13 formed between the end of the third rod 11 and the inner wall of the support groove 10.

[0026] Through the above technical solution, the third rod 11 can support the placement plate 9, increasing the stability of the support.

[0027] As a preferred embodiment, the first hinge shaft 2 and the second hinge shaft 4 are respectively threaded with nuts at both ends and fit tightly to form a damping structure.

[0028] Through the above technical solution, the damping structure can achieve limiting in the folded state.

[0029] As a preferred embodiment, the third hinge shaft 8 is externally fixed with a limiting ring 14, and the backrest 6 and the support plate are made of plastic so that they can generate electrostatic adsorption when they are closed.

[0030] As a preferred embodiment, a magnetic 15 and an adsorption material 16, both sheet-like, are installed between the connecting surfaces of the chair back 6 and the support plate to achieve positioning when folded.

[0031] Through the above technical solutions, electrostatic adsorption or magnetic adsorption can achieve the limitation of the folded state.

[0032] As a preferred embodiment, the bottom of the first rod 3 and the second rod 5 are fixed with several silicone anti-slip pads of existing structure to increase the stability of the support.
