There is the patent relevant to folding desk/chair at present, open (bulletin) number: the CN202891150U of such as Chinese patent mandate, open (bulletin) day: 2013.04.24 utility model patent discloses a kind of integrated office tables and chairs of foldable for storage, comprise base plate and side plate, described base plate and side plate hinge-connection, base plate is etched with rectangular channel, in rectangular channel, seat is installed, seat is fixed in groove by horizontal rotating shaft, the top of seat is fixed with seat support by vertical rotating shaft, and vertical rotating shaft is arranged on the side position that keeps to the side of seat support and seat; Described side plate is etched with rectangular channel, is provided with table in rectangular channel, table is fixed in groove by horizontal rotating shaft, and the top of table is fixed with table support by vertical rotating shaft, and vertical rotating shaft is arranged on the side position that keeps to the side of table support and table.And for example open (bulletin) number: the CN2647123 of Chinese patent mandate, open (bulletin) day: 2004.10.13 utility model patent discloses a kind of foldable combination all-in-one-piece Portable combined table and chair, comprise many chair and a desktop formation, whole desktop is made up of two pieces, left and right desktop, two table legs that can fold are joined in the bottom surface of every block desktop, after two table leg doublings of every block desktop are laminated on the bottom surface of desktop, again two pieces of desktop doublings are just become one " portable chest " altogether, joint-stool is by backrest, chair surface, slip pole, front support leg, dual-active joint pole, back leg, chair locating shaft forms, launch successively during use to become chair, the used time is not folded into flat shape and puts in " portable chest ".Although above-mentioned tables and chairs energy stored collapsed, complex structure, cost is high, and area occupied is large, be not suitable for the use of the scene such as field trips, travelling, and tables and chairs is independently, structurally do not realize integration.
Utility model content
The purpose of this utility model is to provide a kind of folding integration tables and chairs, and after launching, desk uses together with chair, and take up room little, structure is simply ingenious, and cost is low, compares existing folding dining table and chair, is more suitable for single outdoor use; And then make up the deficiencies in the prior art.
For achieving the above object, the utility model provides following technical scheme: a kind of folding integration tables and chairs, comprise upper and lower two-layer seat, the both sides of described upper strata seat have chute, be connected to by connecting rod and two rear support legs, junction is pin mode and connects, and located by the alignment pin of front support leg both sides, during expansion, upper strata seat rotates up disengaging shop bolt around connecting rod, again micro-for lower floor's seat lift connecting rod is rotated smoothly after orientate 180 ° of angles as by the shop bolt on rear support leg, rotating upper layer seat makes chute snap in arcuate guide key on front support leg again, fixed by the arcuate guide key of backrest and link supports and backrest both sides, now the reverse side of upper strata seat serves as desktop, lower floor's seat serves as chair, thus achieve tables and chairs integration using function.As regained on former for upper strata seat road and lower floor's seat coincidence, by front support leg both sides pin location, only chair-function can be played.Time folding, first upper strata seat be lifted away from shop bolt, then lift lower floor's seat, according to common folding seat folding and retraction.
Further, described linkage is provided with arc groove and realizes positioning function and pin hole realizes linkage function.
Further, described rear support leg is provided with draw-in groove and shop bolt to realize positioning function and support function.
Further, both sides, described front support leg device top are provided with arcuate guide key, pin and backrest to realize positioning function and support function.
Further, described brace is for connecting lower floor's seat and rear support leg.
Further, described lower floor's seat both sides are provided with pin hole to realize linkage function.Lower floor's seat can rotate around pin, by brace by front and back supporting leg separately, relies on the fluting on rear support leg realize location and support.
Further, seat panel device both sides, described upper strata are provided with chute and pin, realize positioning function and linkage function respectively.Upper strata seat can rotate around connecting rod, and after connecting rod rotates 180 °, then rotating upper layer seat slips in the arcuate guide key of front support leg and locates, and upper strata seat relies on the back rest supports of front support leg to become desktop.
Compared with prior art, the beneficial effects of the utility model are, these folding integration tables and chairs:
1, upper strata seat is connected with two rear support legs by connecting rod, after only connecting rod need being rotated 180 °, then is rotated around connecting rod by upper strata seat, chute snaps in the arcuate guide key on front support leg, and upper strata seat relies on connecting rod and back rest supports, can be launched into desktop, easy to use, fast.
2, tables and chairs link together, and do not need dismounting and install, realizing tables and chairs integrated function, upper strata seat keeps level under backrest and link supports, and smart structural design is simple, takes up room little, cost is low, easy to carry, effectively can also contain and lift up cross-legged bad habit.
