AI Technical Summary
Existing teaching chairs are inconvenient to move, especially multifunctional teaching chairs that can be reclined or used for storage, which are heavy and difficult to move, making it difficult to meet the needs of students.
The chair is designed with a combination of elastic device and rolling component. When a person stands up, the elastic device lifts the chair, and the rolling component protrudes from the lowest point of the chair leg to facilitate movement. When a person sits down, the elastic device compresses, and the rolling component contacts the ground to ensure the chair is stable.
This design enables convenient movement and stable seating of the teaching chairs, meeting students' needs and improving their convenience and stability.

Abstract
Description
Technical Field
[0001] This utility model relates to a teaching chair, and more particularly to a teaching chair that can be easily moved. Technical Background
[0002] Teaching chairs often need to be moved frequently during use, but most existing teaching chairs are inconvenient to move, especially multi-functional teaching chairs that can be reclined for rest or have storage, which are heavy and difficult to move, making them inconvenient for students to use. Utility Model Content
[0003] To overcome the problem of existing school chairs being inconvenient to move, this utility model provides a school chair that is easy to move. Utilizing the setting of an elastic device and a rolling component, when a person stands up, the elastic force lifts the school chair, at which time the rolling component pops out beyond the lowest point of the chair legs, making the school chair easy to move; after a person sits down, the rolling component is pressed back so that the chair legs contact the ground, and the school chair remains stable and will not slide around. Therefore, it is easy to move and also ensures the stability of the person when seated.
[0004] To achieve the above objectives, the present invention adopts the following technical solution:
[0005] This utility model provides a portable teaching chair, including a backrest, a seat, and legs. The seat is mounted on the legs, and the backrest is located behind the seat. At least two rolling components are located at the bottom of the chair. An elastic device is provided between the rolling components and the chair to lift it up. When a person sits down, the elastic device compresses, causing the bottom of the chair legs to contact the ground. When a person stands, the elastic device lifts the chair, and the rolling components protrude beyond the lowest point of the chair legs, facilitating movement. When a person sits down, the elastic device compresses, causing the bottom of the chair legs to contact the ground, preventing the chair from moving easily and ensuring stability when seated.
[0006] Furthermore, the elastic device is a spring, and the bottom of the chair leg is provided with a mounting groove. The spring and the rolling component are placed in the mounting groove, with the spring pressed on top of the rolling component. The mounting groove at the bottom of the chair leg facilitates the accommodation of the spring and the rolling component and is easy to process.
[0007] Furthermore, the rolling component includes ball bearings that can rotate 360°, facilitating the movement of the teaching chair in all directions.
[0008] Furthermore, the rolling component includes a tray and ball bearings. The tray has an upper end and a lower end. The ball bearings are rolled and embedded in the lower end of the tray and protrude from the lower surface of the tray. A fixing plate is arranged around the lower end of the tray, and the fixing plate is fixedly connected to the bottom of the chair leg. The fixing plate has a through hole, and the lower end of the tray is placed in the through hole and matches the shape of the through hole. The lower end of the tray can slide up and down along the through hole. When the ball bearings at the lower end of the tray slide down to the bottom under the action of the spring force, they can protrude from the lowest point of the bottom of the chair leg, thus lifting the teaching chair. The upper end of the tray is placed above the fixing plate and cannot pass through the through hole. The fixing plate blocks the upper end of the tray, preventing the spring and rolling component from falling out of the mounting groove. The lower end of the tray, i.e., the rolling end, of the rolling component can slide up and down through the through hole, so that the teaching chair can be lifted or pressed down under the action of the spring force.
[0009] Furthermore, the upper end of the tray is plate-shaped, and evenly distributed clamping plates are fixed in the mounting groove. The clamping plates clamp the edge of the upper end of the tray, and the upper end of the clamping plates clamps the edge of the spring. The clamping plates prevent the spring and rolling components from shifting in the horizontal direction, thus improving the stability during use.
[0010] Furthermore, the upper part of the tray is hexagonal, and six clamping plates are evenly distributed in the mounting groove. The hexagonal design further improves the stability during use.
[0011] Furthermore, a storage box is provided under the seat, which makes it convenient for students to place their belongings and improves the ease of use of the teaching chair.
[0012] Furthermore, a backrest is hinged to the back of the seat, and the backrest can be rotated for easy rest.
[0013] The beneficial effects of this invention lie in the fact that, through the design of the elastic device and the rolling component, the magnitude of the force exerted on the elastic device changes when a person sits down and stands up, causing the teaching chair to be raised or lowered. When a person sits and stands up, the elastic force pushes the rolling component out of the lowest point of the chair legs, lifting the teaching chair. The rolling component facilitates movement of the teaching chair, and the ball bearings allow for flexible movement in any direction. When a person sits down, the rolling component is pressed back, the bottom of the chair legs contacts the ground, and the teaching chair is less likely to move. Therefore, it ensures both convenient movement of the teaching chair and stability when seated, making it easy to use. Attached Figure Description

[0021] To better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, the specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.
[0022] See appendix Figure 1-5 This embodiment of a portable teaching chair includes a backrest, a seat, and legs. The seat is mounted on the legs, and the backrest is located behind the seat. At least two rolling components are located at the bottom of the teaching chair. An elastic device is provided between the rolling components and the teaching chair to lift the teaching chair. The elastic device enters a compressed state after a person sits down, causing the bottom of the legs to contact the ground.
[0023] In this embodiment, the elastic device is a spring, and the bottom of the chair leg is provided with a mounting groove. The spring and the rolling component are placed in the mounting groove, and the spring is pressed on top of the rolling component.
