Description
Technical field
The rotatable desk and chair utility model of this integral type relates to the place of auditorium, rally, especially relates to the teaching equipment in school classroom, laboratory.
Background technology
At present, the desk and chair in teaching equipment generally has two kinds of structures: one is that desk and bench single-piece are arranged in pairs or groups, and desk and drawer are integrally attached on desk support as one, not collapsible, and bench chair can not movement arbitrarily; Two are. desk and chair are fixed on ground as an overall large area, and desk and drawer are as being integrally attached on desk support, not collapsible, and chair can make seat fold by middle hinge to improve space availability ratio.Above two kinds of structure desks and drawer integral matching all not collapsible, seat can also very narrow and small with the spacing of desk after upset, fully do not improve space availability ratio, cause and occupy a large amount of spatial volume, not only cause student in turnover due to the little inconvenient left and right turnover in space, and cleaning the classroom and also there is larger dead angle in tables and chairs sanitation and hygiene.On the other hand, desk and chair is non-rotatable, the turnover of extremely inconvenient front and back, and student must arrive first corridor from position of controlling oneself to front-seat or back court position and detours or cross, very not humane.
Summary of the invention
The purpose of this utility model is: the deficiency overcoming above-mentioned existing desk and chair, according to principle and the ball catch feature of four-bar linkage, structure, carry out improvement to existing desk and chair have and fully can improve space availability ratio, the rotatable desk and chair of rotatable integral type.
The technical scheme that the utility model adopts is as follows.
The utility model, on chair, improves the structure of existing seat, carries out the folding of seat by four-bar linkage.Seat one end is connected with desk column holder middle-end by hinge, and the other end is connected with seat connecting rod by pin, and form rocking bar, seat connecting rod comprises a connecting rod and a side link, and the seat connecting rod other end is connected on desk column holder lower end by pin.Namely seat, seat connecting rod, desk column holder form four-bar mechanism, and seat both sides respectively have one group.
The utility model, on desk, improves the structure that desk can not fold, and carries out the folding of desk by four-bar linkage.Desk is the hollow box minor structure that thickness is less, and desk box inside is provided with a ball catch, and desk box is the desk lid of a upset, desk covers a protruding pin corresponding with ball catch.Under desk box, one end is connected with desk column holder upper end by hinge, and the other end is connected with desk box connecting rod by pin, and form rocking bar, desk box connecting rod comprises a connecting rod and a side link, and the desk box connecting rod other end is by pin and desk column holder middle-end.I.e. desk box, desk box connecting rod, desk column holder forms four-bar mechanism, and desk box both sides respectively have one group.
The utility model is on drawer, and being integrally attached on desk drawer and not collapsiblely improving, drawer has two.One is the hollow parts in desk box; Two is connect an auxiliary drawer by two isometric parallel connecting rods under desk box, and namely desk box, isometric parallel rod, auxiliary drawer form chair parallel-crank mechanism, and desk box both sides respectively have one group.
The utility model is on desk post column holder, improve desk column holder is non-rotatable, desk column holder profile is a bite word, desk column holder both sides end face bottom part does not have little groove, be a circular configuration in the middle part of desk column holder low side, circular central is a circular shape through hole, and manhole bottom is divided into macropore, be provided with a thrust bearing in macropore, both sides, dish lower surface, garden are separately installed with a protruding pin.Be an I-shaped structure firm banking under desk column holder, base both sides have a collision bead respectively, are a disc structure in the middle of base, and be a circular through holes in the middle of disk, both sides, base disk upper surface have two 1/4th incomplete circular grooves.Base and column holder are bolted, and nut is fixed.
Adopt above scheme the beneficial effects of the utility model to be: desk box, seat, handrail, desk column holder integral structure, seat front, the desk that desk box uses as a rear classmate.When four-bar mechanism is in dead-centre position during use, desk box and seat can be carried out expansion the same with general desk and chair, auxiliary drawer can amplification quantity books, can by seat and desk box and the substantially same straight line of desk column holder time folding, desk box can drives drawer fold together, in desk box hollow parts can ensure Folding desk box inside books do not drop out, fully improve space availability ratio, be convenient to cleaning, the turnover of convenient left and right.Desk column holder can drive structure on desk column holder to rotate together, same convenient front and back turnover.
