A kind of portable multifunctional tables and chairs
Technical field
The utility model relates to a kind of portable multifunctional tables and chairs.
Background technology
existing desk and Chair structure and function are all separated substantially, or connect by simple structure, although part table sizes is adjustable, structure is more complicated, and controlled variable is limited, and tables and chairs function singleness is difficult to provide diversified function.
Summary of the invention
The utility model improves the problems referred to above, the technical problems to be solved in the utility model be existing desk and Chair structure and function separately, function singleness, and structure is comparatively complicated.
Specific embodiments of the present utility model is: a kind of portable multifunctional tables and chairs, comprise a rectangular-shaped back frame, in described back frame, be provided with the axostylus axostyle that can move up and down along frame height direction, described shaft rod upper sleeve is provided with can be around the seat of spindle rotation, and described seat bottom surface is provided with scalable leg.
Further, described back frame comprises two support bars of a pair of longitudinal setting, described two post uppers are connected with cross bar, described two support bar middle parts are provided with gathering sill, described axostylus axostyle two ends are through gathering sill, and be provided with hold-down nut, in described gathering sill short transverse, be arranged at intervals with the circular hole that several diameters are greater than gathering sill width, the width of described hold-down nut is less than gathering sill width, the length of hold-down nut is greater than gathering sill width, in the time that hold-down nut moves to circular hole, rotating nut makes on nut card and circular hole, thus fixing seat height.
Further, described extending foot comprises sleeve pipe and be sheathed on the expansion link in sleeve pipe, and described sleeve pipe is hinged by loose-leaf, and described expansion link is provided with snak link, and described sleeve pipe is provided with the through hole stretching out for snak link.
Further, described scalable leg is arranged at the front side of seat bottom.
Further, described seat edge is provided with projection or the groove that can splice mutually with other seat edges.
Compared with prior art, the utlity model has following beneficial effect:
(1) collapsible: the seat of the utility model design and the feet of below adopt mode rotatable or that loose-leaf is hinged to connect, in the time not needing to use, as long as it is folded up and is placed on corner, take up room very little, for user's daily life provides great facility.
(2) liftable: by rotating nut, the height of adjustment axle, realizes the adjusting of seat height.And can realize the conversion of Cain and Abel.
(3) realize double chair conversion by the combination variation that connects two individual chair: can, according to the demand of number, carry out individual chair, double chair is changed, and realize the function of desk and chair simultaneously.
(4) adjustable table size and shape: in the time that structure becomes desk form, multiple stands can be spliced into the large desk of difformity and size.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in more detail.
As shown in Fig. 1~2, specific embodiments of the present utility model is: a kind of portable multifunctional tables and chairs, comprise a rectangular-shaped back frame 10, described back frame 10 comprises two support bars 110 of a pair of longitudinal setting, described two post uppers are connected with cross bar 120, described in described back frame 10, two support bar 110 middle parts are provided with gathering sill 111, in back frame 10, be provided with the axostylus axostyle 20 that can move up and down along framework 10 short transverses, axostylus axostyle 20 two ends are through gathering sill 111, axostylus axostyle 20 two ends are provided with hold-down nut 210, in gathering sill short transverse, be arranged at intervals with the circular hole 112 that several diameters are greater than gathering sill width, it is rectangular-shaped that described hold-down nut 210 is class, hold-down nut 210 width are less than gathering sill width, the length of hold-down nut is greater than gathering sill width, when hold-down nut 210 rotates extremely, in the time that hold-down nut 210 moves to circular hole, rotating nut 210 makes on nut length direction card and circular hole, thereby the height of fixed axostyle, on described axostylus axostyle 20, being arranged with can be around the seat of spindle rotation 30, thereby condition the height of seat.
Seat 30 bottom surfaces are provided with scalable leg 40, and extending foot 40 comprises sleeve pipe 410 and be sheathed on the expansion link 420 in sleeve pipe 410, and described sleeve pipe is hinged by loose-leaf, and described expansion link is provided with snak link, and described sleeve pipe is provided with the through hole stretching out for snak link.Through hole can need to arrange according to length multiple, need to stretch time, press snak link button and carry out the flexible operation of expansion link 420 simultaneously, when run on sleeve pipe through hole time, eject at the effect knob down of spring,
Seat 30 relies on two support bars 110 and the extending foot 40 of back frame 10 to support.Extending foot is arranged at the front side of seat bottom.
Seat 30 can form desktop after raising, and seat 30 edges are provided with projection or the groove that can splice mutually with other seat edges, the seat of multiple tables and chairs 30 can be spliced into the larger seat of difformity and size.
The foregoing is only preferred embodiment of the present utility model, all equalizations of doing according to the utility model claim change and modify, and all should belong to covering scope of the present utility model.
