Embodiment Construction

[0012] Below in conjunction with accompanying drawing, the technical scheme that the technical problem of a kind of student table and chair that prevents collapse of the present invention is taken is further explained: its structure is as shown in accompanying drawing, mainly by main table and chair 1; Hinge 2; Stool board 3; Outrigger 4; 90 degree hinge 5 forms. In terms of structure and its combination, the technical features of the collapse-preventing student desk and chair of the present invention are: the main desk and chair 1 and the stool board 3 are connected by a hinge 2, which can make the stool board 3 rotate so that the stool board 3 is parallel to the ground In this way, it can be used at ordinary times, but the stool board 3 will be inclined downward after a long time of cyclical alternating force; the outrigger 4 is connected with the stool board 3 through a 90-degree fixed hinge 5, and the outrigger 4 is folded into 90 degrees perpendicular to the ground, just ...

Abstract

A student table and chair which prevents collapse belongs to the technical field of student learning equipment. The main purpose of designing the student desk and chair to prevent collapse is to solve the situation that the stool board is inclined downward due to the action of alternating force that makes the screws loose due to the long-term cyclic use of the students. A student table and chair to prevent collapse, which is mainly composed of a main table and chair, a stool board, outriggers, a hinge, and a 90-degree hinge. , to achieve the state that the stool is parallel to the ground, the outriggers are connected to the stool through 90-degree fixed hinges, and the outriggers can be folded into 90 degrees perpendicular to the ground to play the role of supporting the stool.

Description

[0001] (1) Technical field [0002] The invention belongs to the technical field of student learning equipment, and in particular relates to a student table and chair for preventing collapse. [0003] (2) Background technology [0004] It is often found that after the school desks and chairs are used for a period of time, the stool surface will tilt downward, and students will feel uncomfortable when sitting. Therefore, the invention of a student desk and chair that prevents collapse solves the above problem. [0005] (3) Contents of the invention: [0006] The main purpose of the collapse-proof student desk and chair of the present invention is to solve the situation that the stool board is inclined downward due to the action of alternating force that makes the screws loosen after long-term cyclic use by students. [0007] The new technical scheme adopted by the present invention to solve the above-mentioned technical problems is realized in the following way: the student des...
