Abstract
The utility model, relating to a removable chair, belongs to furniture technology field, especially to the removable chair. Most of the removable chairs are characterized by unstable structure, less bearing weight and easy to be loosened. The utility model divides the chair into three parts, a back with legs (1), a seat board (2) and a removable leg (3). The seat board (2) inserts into the back (1) and connects to a spiral column (14). The short connecting column (5) positioned on the seat board (2) inserts into the removable chair legs and connects to the spiral column. The fixed leg (4) of the back has a bearing convex (15) at the connecting part at the lower section of the concave slot. The structure, featuring block connection or combination of block and spiral columns, is stronger than block connection or sleeve connection or spiral connection, which is able to bear heavier weight and is difficult to be moved.
Description
Technical field
The utility model belongs to furniture technical field, particularly removable chair.
Background technology
Chair is a furniture commonly used, and for the ease of packed and transported and not time spent stacking, people have invented multiple removable chair, and its structure also has nothing in common with each other, but many removable chairs in use dismounting place structural instability, to bear weight less.
Summary of the invention
The purpose of this utility model provides the stable removable chair of disassembly and assembly structure when using, and is convenient to packed and transported after breaking and stacks chair.
The structure of the removable chair of the utility model is: chair is divided into three parts: backrest 1, seat board 2 and the removable chair pin 3 of band chair pin are that clamping is connected with double-screw bolt 14 again with seat board 2 with the backrest 1 of being with the chair pin again; Promptly overlap clamping and be connected with double-screw bolt again and be connected being fixedly coupled short column 5 and removable chair pin 3 on the seat board 2.Side or structure that this cover clamping or clamping and double-screw bolt are connected, than single use cover clamping or clamping, that single use double-screw bolt connects is more firm, bear weight bigger, be difficult for loosening.
Seat board 2 with the concrete structure that backrest 1 clamping of being with the chair pin and double-screw bolt are connected is: be fixed with sidewall 6 around seat board 2 lower edge, the outer rim of sidewall 6 is made groove 7, the shape of groove 7 matches with the junction shape of fixing feet 4, makes in 4 one-tenth clampings of groove 7 and fixing feet.The connecting portion of fixing feet 4 is any shape, and groove 7 is just made the same shape of size shape, and groove 7 encases the part of fixing feet 4, makes that groove 7 can not rotate, sidewall 6 can not rotate, seat board 2 can not rotate.Groove 7 and fixing feet 4 best elder generations use an angle of 90 degrees, also can select other degree angle for use, but generally should not select arc.Double-screw bolt 14 or pin connected mode are the wedging positions in groove 7 and fixing feet 4, pass through hole 8 on the sidewall 6 with double-screw bolt 14 or pin, are connected with internal thread bag hole 9 on the fixing feet 4, and embedding then with screwed pipe in the metal in the internal thread bag hole 9, double-screw bolt connects more firm.The structure that is connected of backrest 1 clamping and the double-screw bolt of seat board 2 and band chair pin like this, the backrest 1 that makes seat board 2 and band chair pin is by the firm one that is fixed into.
Seat board 2 with the concrete structure that removable chair pin 3 cutting ferrules connect with double-screw bolt is connected is: seat board 2 bottoms are provided with depression shape and are connected short column 5, the backrest 1 of general band chair pin has two fixing chair pin, then seat board 2 bottoms only need two depression shapes connection short columns 5 to be used for being connected with two removable chair pin 3, connect 5 of short columns and is connected when also can only establishing a depression shape, easily not but chair is unstable with a removable chair pin 3; A plurality of depression shapes connection short columns 5 can also be set be connected, become the chair of a plurality of removable chair pin 3 with a plurality of removable chair pin 3.It should be firm connection that seat board 2 bottoms are connected short column 5 with depression shape.For removable chair pin 3 connects with interior depression 11 cutting ferrules that depression shape is connected short column 5, one end of removable chair pin 3 is established clip-connecting rod 10, the shape of clip-connecting rod 10 is connected with form fit with the size that depression shape is connected the interior depression 11 of short column 5, clip-connecting rod 10 is fastened in the interior depression 11 becomes tight fit.In order to allow removable chair pin 3 not drop out interior depression 11, also establish between clip-connecting rod 10 and the depression shape connection short column 5 and be threaded: specifically be to be provided with chair pin double-screw bolt 12 on circular clip-connecting rod 10 tops, spiral shell cave 13 in being provided with at the bottom of the cave of interior depression 11, chair pin double-screw bolt 12 matches with interior spiral shell cave 13 sizes and shape, when rotating removable chair pin 3, circular clip-connecting rod 10 be fastened in circular in the depression 11, chair pin double-screw bolt 12 and interior spiral shell cave 13 are again to be threaded simultaneously, this syndeton is very stable, is difficult for loosening.
The advantage of the removable chair of the utility model is: dismantled and assembled, backrest, seat board and the removable chair pin of the three parts band chair pin that splits into are convenient to packed and transported and stacking, particularly with the backrest of chair pin and clamping between the seat board and the integrated structure that is spirally connected, the integrated structure that also has the cutting ferrule of seat board and removable chair pin to connect and be spirally connected, make the removable chair of the utility model more stable than the combining structure of existing multiple dismounting chair, bear weight greatly, more difficult loosening.
