Abstract

The utility model relates to a steel-plastic lifting desk and chair. The utility model is characterized in that the steel-plastic lifting desk and chair is composed of a steel-plastic lifting desk 1 and a steel-plastic lifting chair 2 which forms a complete provided with the steel-plastic lifting desk 1. The surface 1.1 of an engineering plastic desk is fixed with the box 1.2 of an engineering plastic desk, and the upper end of the bracing frame 1.3 of a metal pipe desk is inserted in the plug socket 1.4 of the bracing frame of the desk inside the box 1.2 of an engineering plastic desk, while the lower end is sheathed in the erecting foot holder 1.5 of the engineering plastic desk. The erecting foot holder 1.5 of an engineering plastic desk is fixed with the horizontal foot holder 1.6 of an engineering plastic desk. The surface 2.1 of the engineering plastic chair and the back support 2.2 of the engineering plastic chair form integration by heat pressing or are mutually fixed. The upper end of the bracing frame 2.3 of the engineering plastic chair is inserted in the plug socket 2.4 of the chair bracing frame under the surface 2.1 of the engineering plastic chair, while the lower end is sheathed in the erecting foot holder 2.5 of the engineering plastic chair. The erecting foot holder 2.5 of the engineering plastic chair and the horizontal foot holder 2.6 of the engineering plastic chair are fixed.

Description

Steel is moulded up-down desk and chair

Technical field

The utility model relates to teaching of a kind of school classroom, auditorium and lecture apparatus, particularly a kind of student or listen a speaker to say that the steel of use moulds up-down desk and chair.

Background technology

1, existing desk and chair, the overwhelming majority is to be the raw material manufacturing with timber, satisfy various teaching of China and lecture tables and chairs, timber that must thousands upon thousands tons of preciousnesses of cost.And excessive disafforestation resource to the also policies such as woods, the ecological balance, water and soil conservation, motherland's greening of root of moving back of China, is a kind of antagonism and harm.

2, wood material is very limited service time, imported timber and make good use of timber and do desk and chair, and cost is too high again, and applying unit and school can hold and can't stand.

3, timber desk when height of doing fixing, i.e. timber desk and chair lifting can't be adjusted, inconvenient student's use.

Summary of the invention

The purpose of this utility model is to disclose a kind of timber that do not use to make, and the steel that durable in use and height can the lifting lift adjustment is moulded up-down desk and chair.

For reaching the technical method that above-mentioned purpose adopts be

Steel is moulded up-down desk and chair and is moulded same table 1 and steel by steel and mould that chair lift 2 is supporting to be constituted.

Engineering plastics desk face 1.1 fixes with engineering plastics desk case 1.2, metal tube desk bracing frame 1.3 the higher authorities, insert in the desk bracing frame jack 1.4 in the engineering plastics desk case 1.2, following is inserted in the engineering plastics desk erects foot rest 1.5, and the engineering plastics desk is erect foot rest 1.5 and fixed with the horizontal foot rest 1.6 of engineering plastics desk.As shown in Figure 1, 2.

Engineering plastics tablet chair seat surface 2.1 is hot pressed into an integral body with engineering plastics tablet chair backrest 2.2 or fixes, metal tube tablet chair bracing frame 2.3 the higher authorities, in the tablet chair bracing frame jack 2.4 below the insertion engineering plastics tablet chair seat surface 2.1, following is inserted in the engineering plastics tablet chair erects foot rest 2.5, and engineering tablet chair plastics are erect foot rest 2.5 and fixed with the horizontal foot rest 2.6 of engineering plastics tablet chair.Shown in Fig. 3,4.

On the metal tube desk bracing frame 1.3 lift adjustment bolt 1.7 is arranged, the metal tube desk is erect foot rest 1.5 lift adjustment hole 1.8; On the engineering plastics tablet chair bracing frame 2.3 lift adjustment bolt 2.7 is arranged, the metal tube tablet chair is erect foot rest 2.5 lift adjustment hole 2.8.Shown in Fig. 1,2,3,4.

Described metal tube desk bracing frame 1.3 is erect foot rest 1.5 by the engineering plastics desk and is inserted in, and the cooperation that is meant both is a sliding fit, and its section configuration is circular, or square or oval or rectangle.Described metal tube tablet chair bracing frame 2.3 is erect foot rest 2.5 by the engineering plastics tablet chair and is inserted in, and the cooperation that is meant both is a sliding fit, and its section configuration is circular, or square or oval or rectangle.

Advantage of the present utility model is

1, steel is moulded raw material and can be satisfied various teaching of China and lecture tables and chairs fully, needn't spend the timber of thousands upon thousands tons of preciousnesses again.To the also policies such as woods, the ecological balance, water and soil conservation, motherland's greening of root of moving back of China, be a kind of great compensation.

2, the utility model is very limited service time, and is more durable in use than timber desk and chair, and cost is not high again, believes the very big welcome that can be subjected to applying unit and school.

3, increased the adjustable function of desk and chair lifting, the desk and chair that log scale is made can't carry out height adjustment, inconvenient student's use.
