Description
Technical field
The utility model belongs to intelligent instructional device technical field, relates to a kind of five-rod linkage triangle self-locking folding table/chair.
Background technology
Current tables and chairs, from profile, by single form gradually transition develop into lift, connect formula etc., more meet the variform of ergonomics.The desk that weak point is mainly reflected in desk and chair generally is fixing can not the moving of level, and this kind of design brought following problem to school table chair:
1) tables and chairs that desktop is completely fixed make classmates in the time that break passes in and out between two arrange seatses, the classmate on both sides, passageway need to rise to one's feet and abdicate the space of turnover, seem so cumbersome, if the classmate in the middle of an arrange seats will leave, the classmate of whole arrange seats will stand up and step down.If just at school time, the order of normally attending class that affects classroom that like this can be serious.
2) tables and chairs that desktop is completely fixed are put the space hold rate in classroom large, when classmate passes in and out between two arrange seatses, if be easy to because of carelessness rub on the legs and feet of tables and chairs, cause unnecessary injury.Because this tables and chairs of table dormant panel are large to space hold rate, make the corner or spot as yet untouched by a clean-up campaign in classroom be difficult to comparatively speaking be swept simultaneously.
3) existing table dormant panel tables and chairs are arranged a spacious classroom for wanting, and are not easy to.Equally, table dormant panel tables and chairs make to want the tables and chairs that remove a classroom also quite to bother.
Utility model content
The purpose of this utility model is to provide a kind of five-rod linkage triangle self-locking folding table/chair, solve in prior art tables and chairs table dormant panel classmate and be difficult between turnover two arrange seatses, and the school table chair problem that when arranging classroom tables and chairs waste time and energy large to classroom space hold rate.
The technical scheme that the utility model adopts is, a kind of five-rod linkage triangle self-locking folding table/chair is installed with the fixing angle bar of desktop at desktop lower surface, and the fixing angle bar front end of desktop is hinged with guide rail, desktop fix angle bar rear end and connecting rod two hinged;
Slide block is installed in guide rail, and connecting rod two other ends and slide block are hinged, and the slide block other end and connecting rod one are hinged, and connecting rod one other end and connecting rod three are hinged, and the fixing angle bar of connecting rod three other ends and stool is hinged, and the fixing angle bar upper surface of stool is installed with stool plate; On guide rail, be installed with crossbeam and backrest, the fixing angle bar of crossbeam and stool is hinged.
Five-rod linkage triangle self-locking folding table/chair of the present utility model, its feature is also:
The fixing angle bar of desktop middle part is installed with spacer, and spacer is provided with hook by bearing pin four, and connecting rod two middle parts are provided with peg, and hook coordinates with peg hook.
The beneficial effects of the utility model are, adopt five-bar mechanism, make desktop and stool rely on this cover five-rod to couple together, by a connecting rod that can slide up and down along guide rail, the power that desktop is rotated with respect to center of rotation passes to stool plate, or the power of rotating with respect to center of rotation of stool plate is passed to desktop, thereby effectively desktop and stool plate are coupled together.After tables and chairs launch, by the two the connection of hook fixing on connecting rod and outstanding peg, the motion in use of a whole set of tables and chairs is limited.In the time not using, unclamp hook and the peg of connection, make fold synchronous by the connection of connecting rod of desktop and stool plate, the occupancy of folding rear space diminishes, and facilitates classmate to pass in and out and hygiene work.
