Abstract

The utility model relates to a multifunctional writing-table, and the aim of the utility model is to solve the technical problems that the height of the table can not be regulated according to students' height, and the deformation of spinal columns can not be prevented. The utility model is mainly composed of a table top, table legs, a bottom surface, regulating nuts, adjustable table legs, a cross beam, a bolt and a bolt hole. The utility model is characterized in that the lower parts of the table legs are arranged on the upper part of the adjustable table legs, and the outer circumference of the bolt penetrates into the inner side of the bolt hole. Devices of writing-table factories are used for bulk production to supply students' requirements.

Description

Multi-functional writing desk

(1) technical field:

The utility model relates to multi-functional writing desk, divides the technical field that belongs to school desk or group of tables by International Patent Classification (IPC) (IPC).

(2) background technology:

At present, the technology about school desk or group of tables existing and that once had was all done very fruitful effort to the demand of multi-functional writing desk, also once designed many outstanding technical schemes.As declaring of the Decree of Patent Office of China on the 23rd October in 2002 by Pang Zhixiang, Granted publication number is CN2517299Y, China Patent No. (ZL) is: No. 02225372.6 utility model patent title is the utility model patent of " Portable table ", the technical scheme that is adopted.Technical elements in school desk or group of tables is a routine of great value invention, but it has solved desktop folding and the panels outside technical problem that is convenient for carrying with handles effectively.But still have some deficits, it also is difficult to separate and must not regulates height according to student's height, can not prevent the technical problem of deformation of spinal column.

(3) summary of the invention

The purpose of this utility model is to provide a kind of multi-functional writing desk.Must not regulate height according to student's height to separate, can not prevent the technical problem of deformation of spinal column.

The new technical scheme that above-mentioned technical problem to be solved in the utility model adopted is: multi-functional writing desk of the present utility model mainly is made of desktop, table leg, bottom surface, adjusting nut, adjustable table leg, crossbeam, bolt, bolt hole.

In shape, structure and combination thereof, the total essential features of multi-functional writing desk of the present utility model and immediate prior art is: the following nail joint of desktop is in the upper end of table leg, the two ends nail joint of crossbeam is on the top of table leg, be combined into the integrative-structure of table shape, function has been that desk is used for function of learning.The side nail joint of bottom surface is combined into the integrative-structure of flat shape in the outside of crossbeam, and function has been the effect that the table thorax is used for putting thing.In shape, structure and combination thereof, the multi-functional writing desk of the present utility model technical characterictic different with immediate prior art is: the bottom of table leg is placed on the top of adjustable table leg, the excircle of bolt penetrates the inboard of bolt hole, be combined into the bascule of square column shape, function is to regulate table height according to different student's heights, prevents that the student from causing the effect of deformation of spinal column because of desk height discomfort.So just reach multi-functional writing desk of the present utility model and separated and to regulate height according to student's height, can not prevent the purpose of the technical problem of deformation of spinal column.

The beneficial effect of the multi-functional writing desk of utility model is: the utility model must not be regulated height according to student's height for separating, and can not prevent that the technical scheme that technical problem adopted of deformation of spinal column from having compared a place's advantage and an improvement with existing with the technology about school desk or group of tables that once had:

First, because the bottom of having designed table leg in the technical scheme of multi-functional writing desk of the present utility model is placed on the top of adjustable table leg, the excircle of bolt penetrates the inboard of bolt hole, be combined into the bascule of square column shape, so easier solution is regulated table height according to different student's heights, prevent that the student from causing the technical problem of deformation of spinal column because of desk height discomfort.

(4) description of drawings:

Accompanying drawing provides the structural representation of multi-functional writing desk of the present utility model:

Fig. 1: the overall structure schematic diagram that is multi-functional writing desk of the present utility model;

Fig. 2: the leg structure of collapsible schematic diagram that is multi-functional writing desk of the present utility model;

The label declaration at each position in the schematic diagram:

1 desktop, 2 table legs, 3 bottom surfaces, 4 adjusting nuts

5 adjustable table leg 6 crossbeams 7 bolts 8 bolts hole

(5) specific embodiment:

Below in conjunction with accompanying drawing, must not regulate height to multi-functional writing desk of the present utility model according to student's height for realizing separating, can not prevent that the optimal way of the technical scheme that the technical problem of deformation of spinal column is taked is described further:

Its static structure: see also accompanying drawing: as shown in the figure, multi-functional writing desk of the present utility model mainly is made of desktop 1, table leg 2, bottom surface 3, adjusting nut 4, adjustable table leg 5, crossbeam 6, bolt 7, bolt hole 8.Its major part desktop 1, bottom surface 3, adjusting nut 4, crossbeam 6, bolt 7 are selected for use by market.Its table leg 2 is square column shapes, is material with timber, makes through the sawing processing and forming.Its adjustable table leg 5 is square column shapes, is material with timber, makes through the sawing processing and forming.

In shape, structure and combination thereof, the total essential features of multi-functional writing desk of the present utility model and immediate prior art is: the following nail joint of desktop 1 is in the upper end of table leg 2, the two ends nail joint of crossbeam 6 is on the top of table leg 2, be combined into the integrative-structure of table shape, function has been that desk is used for function of learning.The side nail joint of bottom surface 3 is combined into the integrative-structure of flat shape in the outside of crossbeam 3, and function has been the effect that the table thorax is used for putting thing.In shape, structure and combination thereof, the multi-functional writing desk of the present utility model technical characterictic different with immediate prior art is: the bottom of table leg 2 is placed on the top of adjustable table leg 5, the excircle of bolt 7 penetrates the inboard of bolt hole 8, be combined into the bascule of square column shape, function is to regulate table height according to different student's heights, prevents that the student from causing the effect of deformation of spinal column because of desk height discomfort.

Below by using method, further set forth the dynamic structure relation of the multi-functional writing desk of the utility model: in use, when needs are regulated height, according to physical principle, at first unclamp bolt 7, mix up height then, tight a bolt 7 then again, thereby finish adjustable for height task.

In use, when needs prevent deformation of spinal column,, at first mix up the desk height, prevent deformation of spinal column because of highly suitable then, thereby finish the task of preventing student's deformation of spinal column according to physical principle.So just realized that multi-functional writing desk of the present utility model is separated and to have regulated height according to student's height, can not prevent the technical scheme of the technical problem of deformation of spinal column.

Realize that preferred plan of the present utility model is is material with timber, utilize the basic equipment of writing desk factory, take to produce by batch in a large number,, so just can realize the practical value and the economic worth of multi-functional writing desk of the present utility model better with the demand of supply student circle.
