The classroom tables and chairs that current school uses have tables and chairs to be separated and unfixed form, are inconvenient to manage and do not save space.Also have a fixed bottom boundary with tables and chairs one, this form is too fixing, and chair can not oppositely use, and brings the not convenient of use, can not save space equally, and desktop is not very large simultaneously.It is not very convenient that student uses on classroom.The problems referred to above, urgently to be resolved hurrily.
Summary of the invention
The utility model, for deficiency of the prior art, provides a kind of multifunctional turnover folding table chair.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals: multifunctional turnover folding table chair, comprise holder, the middle part of described holder is vertically provided with column, the upper end hinge of described column is provided with desktop, the lower edge of described desktop is provided with the first support bar by hinge, and the side of described column is provided with groove, and one end of described first support bar is arranged in described groove; The middle part of described column is provided with cross bar, and described cross bar is provided with seat plate by hinge, and described holder is provided with linkage, and described linkage is connected with support, and described support supports described seat plate.Such setting, have the version of tables and chairs one, there is again multiple change to combine to adapt to different service conditions simultaneously, the special construction of desk determines that seat plate can 180 ° of upsets, desktop can do desktop can do backrest again, desk can be folded into the very little state of volume, convenient transport again while of space-saving; When desk normal combination uses, can turn down desk and expand desktop, composition ultra-large type desktop, to meet Special use demand, also can adjust the angle of inclination of desktop as required, desktop is in meet the obliquity that user requires, person's study and work easy to use.
In order to obtain better technique effect, further technological improvement also comprises, and described column is provided with first connecting rod, and described first connecting rod has been connected through the hinge second connecting rod, and the other end of described second connecting rod is arranged on the bracket.
In order to obtain better technique effect, further technological improvement also comprises, and described holder is two pieces of plate bodys be arranged in parallel, and described column is vertically arranged on the middle part of described holder respectively.
In order to obtain better technique effect, further technological improvement also comprises, and the quantity of described desktop is two pieces, and described desktop is symmetricly set on the upper edge of described column by hinge.
The beneficial effects of the utility model are: the version having tables and chairs one, have again multiple change to combine to adapt to different service conditions simultaneously, have very strong use flexibility, and structure is simple, and low cost, can turn down withdrawal, volume is little, and convenient transport, has broad application prospects.

Detailed description of the invention
Below in conjunction with accompanying drawing and detailed description of the invention, the utility model is described in further detail.
See shown in Fig. 1 to Fig. 4, a kind of specific embodiment of the utility model multifunctional turnover folding table chair.Comprise holder 1, described holder 1 is two pieces of plate bodys be arranged in parallel, and described column 2 is vertically arranged on the middle part of described holder 1 respectively.
The middle part of described holder 1 is vertically provided with column 2, the upper end hinge of described column 2 is provided with desktop 3, the quantity of desktop 3 is two pieces, it is symmetricly set on the upper edge of described column 2 by hinge, the lower edge of described desktop 3 is provided with the first support bar 4 by hinge, the side of described column 2 is provided with groove 20, one end of described first support bar 4 is arranged in described groove 20, first support bar 4 slides in groove 20, desktop can be driven to rotate within the scope of 0 degree ~ 90 degree, when two pieces of desktops 3 rotate to parallel with the upper surface of column 2 time, the usable floor area of this desk reaches maximum, the demand of user to large table surface can be met, such as during mechanical drawing, when two pieces of desktops 3 rotate to parallel with the side of column 2 time, this desk is in the state of packing up, and spatial volume is little, convenient carrying and transport.In actual use, user can adjust the angle of inclination of desktop 3 according to actual needs, desktop 3 is in meet the obliquity that user requires, person's study and work easy to use.
Described holder 1 is symmetrically arranged with two groups of linkages 10, described linkage 10 is distributed in the both sides of column 2, linkage 10 is connected with support 7, left and right sides on described column 2 is symmetrically arranged with first connecting rod 11, described first connecting rod 11 has been connected through the hinge second connecting rod 12, and the other end of described second connecting rod 12 is arranged on described support 7, after first connecting rod 11 and second connecting rod 12 being launched, support 7 is fixed, seat plate 6 is put down namely can be used as chair use.
The middle part of described column 2 is provided with cross bar 5, described cross bar 5 is provided with seat plate 6 by hinge, seat plate 6 can be rotated by hinge, when needing to use the chair on the left of column 2, fix the position of the support 7 on the left of column 2, Tipping-up chair panel 6 to the left, is overlapped on support 7, just can be employed; If when needing to use the chair on the right side of column 2, then reversely rotate seat plate 6, its right side at column 2 is made to form chair.Shown in Figure 4, if when not using this desk, seat plate 6 is clipped in the centre of two pieces of desktops 3, saves space.
That more than enumerates is only specific embodiment of the utility model, and obviously, the utility model is not limited to above embodiment.All distortion that those of ordinary skill in the art can directly derive from content disclosed in the utility model or associate, all should belong to protection domain of the present utility model.
