Abstract
The utility model provides a sofa bottom plate wood frame structure, including four frames and a plurality of crossbeam, the grafting structure has all been seted up at the both ends of four frames, and the grafting structure is broach form grafting structure, and four frames pass through grafting structure end -to -end connection in proper order becomes the rectangle frame, is equipped with the crossbeam in the frame of rectangle frame, is equipped with the swallow tail at the both ends of crossbeam, seted up on the rectangle frame with swallow tail assorted dovetail, the crossbeam passes through the swallow tail and the dovetail is connected with the rectangle frame. The beneficial effect of the utility model: it is fixed to adopt between the frame agent of broach form grafting structure cooperation timber gluing to connect, receives the force intensity big, and the coupling part material is unanimous, and inflation coefficient of contraction is unanimous, connects more steadily, and it is better to fix the effect, swallow tail and dovetail design cooperation broach dress grafting structure is used, and when frame at crossbeam both ends received outside pulling force, the crossbeam passes through the swallow tail can be restricted the frame with the dovetail design and take place to remove to the steadiness of reinforcing rectangle frame.
Description
Technical field
The utility model belongs to sofa technical field, especially relates to a kind of sofa bottom plate wooden frame structure.
Background technology
In prior art, sofa bottom plate wooden frame structure is mostly connected to one by nail by four frames, the less stable of rectangle frame, sofa uses nail to stretch out frame for a long time, not only unsightly, also easy damage is caused to sofa epidermis, even scratch user, therefore we design and a kind ofly adopt comb teeth-shaped connected structure and dovetail structure sofa bottom plate wooden frame in mating connection.
Summary of the invention
In view of this, the utility model is intended to propose a kind of sofa bottom plate wooden frame structure, to solve wooden frame instability, connects insecure, caducous problem between frame.
For achieving the above object, the technical solution of the utility model is achieved in that
A kind of sofa bottom plate wooden frame structure, comprise four frames and some crossbeams, the two ends of described four frames all offer connected structure, described connected structure is comb teeth-shaped connected structure, described four frames connect into rectangle frame by described connected structure successively head and the tail, described crossbeam is provided with in the framework of described rectangle frame, dovetail is provided with at the two ends of described crossbeam, described rectangle frame offers the dovetail groove matched with described dovetail, described crossbeam is connected with described rectangle frame with dovetail groove by described dovetail, increase the stability of rectangle frame, prevent the frame at crossbeam two ends from coming off.
Further, described rectangle frame is also provided with one deck base plate, described base plate is made up of some concatenation units, groove is offered in the side of described concatenation unit, opposite side is provided with the convex edge with described groove match, described concatenation unit is spliced into one by described groove and convex edge, and described base plate is fixedly connected with described rectangle frame by rivet.
Further, described dovetail, dovetail groove and connected structure are coated with based Wood Adhesives, strengthen dovetail with between dovetail groove and the fastness that between frame, connected structure is connected.
Further, described crossbeam has 1-3 bar.
Relative to prior art, a kind of sofa bottom plate wooden frame structure described in the utility model has following advantage:
1, adopt comb teeth-shaped connected structure to coordinate based Wood Adhesives to be connected and fixed between frame, large by force intensity, when four frames are subject to the power of inwardly extruding, comb dress connected structure connects more firm, good fixing effect;
2, dovetail coordinates comb to fill connected structure to use with dovetail groove design, and when the frame at crossbeam two ends is subject to outside pulling force, crossbeam can limit frame by dovetail and dovetail groove design and be moved, thus strengthens the steadiness of rectangle frame;
3, because the water content of timber is by the impact of surrounding environment, timber constriction coefficient and coefficient of expansion in different temperature, humidity environment are different, according to traditional rivet interlacement mode, loosening of rivet can be caused in the contraction of timber, expansion, so adopt comb teeth-shaped connected structure and dovetail structure to replace traditional rivet, not only reduce rivet and use cost-saving, and due to connecting portion material consistent, convergent-divergent coefficient is also consistent, and the stability of framework is increased.

Detailed description of the invention
It should be noted that, when not conflicting, the embodiment in the utility model and the feature in embodiment can combine mutually.
Below with reference to the accompanying drawings and describe the utility model in detail in conjunction with the embodiments.
A kind of sofa bottom plate wooden frame structure, comprise four frames 1 and some crossbeams 3, the two ends of described four frames 1 all offer connected structure 2, described connected structure 2 is comb teeth-shaped connected structure, described four frames 1 connect into rectangle frame by described connected structure 2 successively head and the tail, crossbeam 3 described in 1-3 bar is provided with in the framework of described rectangle frame, dovetail 4 is provided with at the two ends of described crossbeam 3, described rectangle frame offers the dovetail groove 5 matched with described dovetail 4, described crossbeam 3 is connected with described rectangle frame with dovetail groove 5 by described dovetail 4, increase the stability of rectangle frame, prevent the frame at crossbeam 3 two ends from coming off, at described dovetail 4, dovetail groove 5 and connected structure 2 are coated with based Wood Adhesives, strengthen dovetail 4 with between dovetail groove 5 and the fastness that is connected of frame 1 connected structure 2.
Described rectangle frame is also provided with one deck base plate, described base plate is made up of some concatenation units 6, groove 7 is offered in the side of described concatenation unit 6, opposite side is provided with the convex edge 8 matched with described groove 7, described concatenation unit 6 is spliced into one by described groove 7 and convex edge 8, and described base plate is fixedly connected with described rectangle frame by rivet.
Assembling process of the present utility model: smear timber adhesive in the dovetail groove 5 first on the dovetail 4 at crossbeam 3 two ends and on frame 1, crossbeam 3 and frame 1 joggle are fixed, then on the connected structure 2 of four edges frame 1, smear timber adhesive, four frames 1 successively grafting are fixed into a rectangle frame; Some concatenation units 6 are spliced into a base plate by groove 7 and convex edge 8, then base plate rivet is fixedly connected with rectangle frame.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
