Abstract
The utility model discloses an improvement structure of a dual-purpose folding sofa bed, which comprise a sofa frame, a sofa backrest, and a sofa seat plate, wherein, the sofa seat plate and the sofa backrest which are arranged on the sofa frame are hinged with the sofa frame, both the sofa backrest and the sofa seat plate are composed of frames, transverse rods, and clamp pieces, corresponding points of both ends of the frames are provided with a plurality of clamp holes, the transverse rods are provided with insertion holes, the peripheries of the clamp pieces are provided with clamping grooves, the inner parts of the clamp pieces are provided with clamping hooks, and the transverse rods are connected with the frames by the clamp pieces. Because the frames, the transverse rods, and the clamp pieces can be totally separated, and in addition, the assembly of the frames, the transverse rods, and the clamp pieces is convenient, the sizes of the frames and the transverse rods are small in packing and transportation, the identical packages can load a plurality of finished products, the packaging volume can be reduced, and the shipment quantity can be increased a plurality of times or by a plurality of times; in addition, the integral structure and the rigidity of the bed can not be damaged, the manufacturing difficulty and the manufacturing workload can be reduced, and the end users can be very convenient by the utility model in the process of installation, and meanwhile, the service life of the bed is prolonged.
Description
Technical field
The utility model relates to a kind of dual-purpose folding bed, and is especially relevant with the structure of bed board, belongs to furniture.
Background technology
For easy to use and saving space, dual-purpose folding bed is most economical material benefit.The bed board structure of general folding seat bed is: backrest and seat all adopt at quadra, and quadra inside evenly is provided with cross bar, and its connected mode is the two ends riveted joint of cross bar or is adhesively fixed on the quadra; Perhaps backrest and seat are an integral panels, are carved with various decorative patterns and pattern on its panel.Because the backrest of prior art is with seat structure dullness and be fixing non-disconnectable formula, causes the dual-purpose folding bed very big volume that occupies in storage and transport process like this, is difficult for packing arrangement, delivery expense height, be inconvenient to again assemble, thus the service life that influences bed.And the parts of these assembling beds are integral body, the difficult repairing and replacing.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of simple in structure, be convenient to transport and assemble, repair and the structural improvement of replacement, dual-purpose Folding sofa bed that cost is low.
The structural improvement of the dual-purpose Folding sofa bed of the utility model, comprise sofa frame, sofa backrest and sofa seat board, sofa seat board and sofa backrest place on the sofa frame, and are that hinge is connected with sofa frame, and the sofa backrest is similar to the sofa seat plate structure, form by comprising frame, cross bar and fastener, the corresponding section, two ends of frame is equipped with some hole clippings, and cross bar is provided with patchhole, and the fastener periphery is provided with draw-in groove, inside is provided with grab, and cross bar is connected on the frame by fastener.
Described fastener is wedge, V-arrangement, external tooth form, internal tooth form or interior external tooth form, and its periphery is provided with draw-in groove.
Described cross bar be "
" shape, its two vertical edge is equipped with patchhole.
Described frame is flush-type, the protruding formula in limit, right-angle type or high-low type.
Described cross bar can be a plate, also can be pipe.
After adopting said structure, the cross section be carve type fastener in use, can be stuck in fastener earlier on the frame, again the two ends of cross bar are pressed in the fastener; After also can connecting fastener and cross bar, be pressed into together again in the patchhole of frame, form the sofa seat board or the sofa backrest of divan, again the sofa seat board is carried out hinge with sofa backrest and sofa frame and be connected, thereby constitute two purpose sofas-beds collapsible or that keep flat.And when to be the fastener of " V " type use in the cross section, then need with the two ends of cross bar respectively with the end riveted joint or the welding of fastener, be pressed into together again in the patchhole of frame, the other end then is stuck on the frame, to form the seat board or the backrest of divan.
The utility model is owing to adopted fastener to connect cross bar and frame, can carry out the loose mail packing to fastener, frame and cross bar during transportation, it is little to take up space like this, and the cost of transportation is low, and each modular construction is simple, installation is easy, if any damaging convenient the repairing and replacing.
