(3) summary of the invention:
The purpose of this utility model is to provide a kind of adjustable tables and chairs.Fix to solve common tables and chairs height, common tables and chairs pattern is single, and the student is with table, can not be according to the people fixed technical problem of chair.
The adjustable tables and chairs that the new technical scheme that above-mentioned technical problem to be solved in the utility model adopted is achieved in that this utility model mainly by: desktop, table frame, spring, pedal, chair frame, bearing, tie rod constitute.Its major part desktop, table frame, spring, pedal, chair frame are selected for use by market.Its desktop is a rectangular shape, is material with the PLASTIC LAMINATED, through the woodwork processing and manufacturing.Its table frame is a table shape, is material with the steel, through rolling, welding processing manufacturing.Its spring is spiral-shaped, is material with the light metal, through the processing and forming manufacturing.
In shape, structure and combination thereof, the total essential features of adjustable tables and chairs of the present utility model and immediate prior art is: the lower position weldering of table frame is connected the upper position of bearing, the upper position weldering of spring is connected the lower position of a frame, be combined into the tetragonal body structure of table shape, function has been the effect of supporting.The both sides fixed-site of pedal is connected an end position of tie rod, and the other end fixed-site of tie rod is connected the upper side position of spring, is combined into " V " word shape bar linkage structure, and function has been the pulling spring action.In shape, structure and combination thereof, the adjustable tables and chairs of the present utility model technical characterictic different with immediate prior art is: the lower position weldering of chair frame is connected the inner side of bearing, the upper position weldering of spring is connected the inner underside position of chair frame, be combined into the spring structure of rectilinear form, function has been the effect of supporting.The lower position weldering of spring is connected the last inner side of bearing, and the upper side position weldering of spring is connected the lower position of chair frame, is combined into the spring structure of rectilinear form, and function has been the effect of flexible chair leg.The both sides fixed-site of pedal is connected two side positions of tie rod, and the end positions of tie rod is fixedly connected on the upper end position of spring, is combined into the bar linkage structure of " V " word shape, and function has been the effect of extension spring.So just realized that adjustable tables and chairs of the present utility model solve common tables and chairs height and fix, common tables and chairs pattern is single, the student with table, chair can not be according to the people purpose of fixed technical problem.
The beneficial effect of the adjustable tables and chairs of utility model is that the utility model is to solve common tables and chairs height to fix, common tables and chairs pattern is single, the student with can not be according to the people fixed technical scheme that technical problem adopted of table, chair and existing and once had about school's long slab stool; The stool of combining with desk or the technology of long slab stool group have been compared three place's advantage and improvement:
First, because the lower position weldering that has designed the chair frame in the technical scheme of adjustable tables and chairs of the present utility model is connected the inner side of bearing, the upper position weldering of spring is connected the inner underside position of chair frame, be combined into the spring structure of rectilinear form, so the technical problem that easier solution is supported.
Second, because the lower position weldering that has designed spring in the technical scheme of adjustable tables and chairs of the present utility model is connected the last inner side of bearing, the upper side position weldering of spring is connected the lower position of chair frame, be combined into the spring structure of rectilinear form, so the technical problem of the flexible chair leg of easier solution.
The 3rd, because the both sides fixed-site that has designed pedal in the technical scheme of adjustable tables and chairs of the present utility model is connected two side positions of tie rod, the end positions of tie rod is fixedly connected on the upper end position of spring, be combined into the bar linkage structure of " V " word shape, so the technical problem of easier solution extension spring.

(5) specific embodiment:
Below in conjunction with accompanying drawing, adjustable tables and chairs of the present utility model are fixed for realize solving common tables and chairs height, common tables and chairs pattern is single, the student with, chair can not the technical scheme that fixed technical problem is taked according to the people optimal way be described further:
Its static structure: please join accompanying drawing: as shown in the figure, adjustable tables and chairs of the present utility model mainly are made of desktop 1, table frame 2, spring 3, pedal 4, chair frame 5, bearing 6, tie rod 7.Its major part desktop 1, table frame 2, spring 3, pedal 4, chair frame 5 are selected for use by market.Its desktop 1 is a rectangular shape, is material with the PLASTIC LAMINATED, through the woodwork processing and manufacturing.Its table frame 2 is table shape, is material with the steel, through rolling, welding processing manufacturing.Its spring 3 is spiral-shaped, is material with the light metal, through the processing and forming manufacturing.
In shape, structure and combination thereof, the total essential features of adjustable tables and chairs of the present utility model and immediate prior art is: the lower position weldering of table frame 2 is connected the upper position of bearing 6, the upper position weldering of spring 3 is connected the lower position of a frame 9, be combined into the tetragonal body structure of table shape, function has been the effect of supporting.The both sides fixed-site of pedal 4 is connected an end position of tie rod 7, and the other end fixed-site of tie rod 7 is connected the upper side position of spring 3, is combined into " V " word shape bar linkage structure, and function has been the pulling spring action.In shape, structure and combination thereof, the adjustable tables and chairs of the present utility model technical characterictic different with immediate prior art is: the lower position weldering of chair frame 5 is connected the inner side of bearing 6, the upper position weldering of spring 3 is connected the inner underside position of chair frame 5, be combined into the spring structure of rectilinear form, function has been the effect of supporting.The lower position weldering of spring 3 is connected the last inner side of bearing 6, and the upper side position weldering of spring 3 is connected the lower position of chair frame 5, is combined into the spring structure of rectilinear form, and function has been the effect of flexible chair leg.The both sides fixed-site of pedal 4 is connected two side positions of tie rod 7, and the end positions of tie rod 7 is fixedly connected on the upper end position of spring 3, is combined into the bar linkage structure of " V " word shape, and function has been the effect of extension spring.
Below by using method, further set forth the dynamic structure relation of these practical adjustable tables and chairs: in use, when needs are regulated the desk height, according to elastic principle, at first use foot pedals 4, spring 3 shrinks then, and table frame 2 glides then again, thereby finishes the task of reducing desktop.
In use, when needs are regulated the chair height, according to elastic principle, the pedal 4 that at first tramps with one's feet, spring 3 shrinks then, and is fixing chair frame 5 and bearing 6 then again, thereby finishes the task of reducing seat.So just realized that the common tables and chairs height of solution of adjustable tables and chairs of the present utility model fixes, common tables and chairs pattern is single, the student with table, chair can not be according to the people purpose of fixed technical problem.
Realize that preferred plan of the present utility model is is material with the steel, utilize the basic equipment of tables and chairs factory, take to produce by batch in a large number,, so just can realize the practical value and the economic worth of adjustable tables and chairs of the present utility model better with the demand of supply cultural circles.
