A kind of member linkage structure of wood furniture
Technical field
The utility model relates to the connection fittings of wood furniture member, relates in particular to a kind of member linkage structure that adopts the furniture that wooden member is formed by connecting.
Background technique
One recessed one protruding cooperating structure is processed in the member joint that common wood furniture of past will be connected usually, utilizes angle of wedge sheet to fill slit between concavo-convex cooperation again, to form drive fit.The material of general angle of wedge sheet is softer, just be squeezed in the slit easily, so angle of wedge sheet also addles easily, use certain hour after, joint, member joint will produce loosening.Wood furniture in the market improves this technology, boring is adopted in the member joint that is connected, pre-embedded bolt, utilize screw that member is connected and fixed, connect more firmly, and detachable between the member that is connected like this, transport more convenient, mounting process is simple, only needs to adopt the screw lock instrument just can operate.But just there is shrinkage pool in the structure that adopts this member to connect on the surface of member joint, even can see the screw that connects locking usefulness, influences the attractive in appearance of wood furniture.
Summary of the invention
The purpose of this utility model provides a kind of both easy disassembly transportation, and processing technology is simple, the member linkage structure of wood furniture easy for installation.
Above purpose can realize by following structures: the joint correspondence of the member of wood furniture is provided with two pairs or more connection shrinkage pool, on the connection shrinkage pool of the joint correspondence of the two ends difference connector element of connecting pin, the length of connecting pin is respectively greater than one of them of the connection shrinkage pool of correspondence, less than the connection shrinkage pool of correspondence and, corresponding connection shrinkage pool has wrapped up connecting pin fully.
Above-mentioned connecting pin is excessively to cooperate or drive fit with being connected shrinkage pool.
The two ends of above-mentioned connecting pin be connected the shrinkage pool end and be provided with chamfering.
Above-mentioned connecting pin is circular, oval, annular or square with the sectional shape that is connected shrinkage pool.
The utility model adopts above structure, the connection that utilizes connecting pin that member is carried out, be assembled into the furniture that needs, the member processing technology is simple like this, helps realizing standardized production, and easy accessibility, transportation volume can be adjusted smallerly, the vestige of outward appearance atresia, more attractive in appearance, be the member linkage structure of fit closely wood furniture.
Description of drawings
Now in conjunction with the accompanying drawings the present invention is further elaborated:
Fig. 1 is the cross-sectional schematic of the utility model two member linkage structures;
Fig. 2 is the scheme of installation of one of furniture of this employing model utility linkage structure;
Fig. 3 is two a scheme of installation of the furniture of this employing model utility linkage structure.
Embodiment
See also shown in Figure 1, the joint correspondence of the member 1,2 of the utility model wood furniture is provided with two pairs or more connection shrinkage pool 11,21, the two ends 31,32 of connecting pin 3 are respectively on the connection shrinkage pool 11,21 of the joint correspondence of connector elements 1,2, the two ends 31,32 of connecting pin 3 be connected shrinkage pool end 11,21 and be equipped with chamfering.Connecting pin 31,32 and the sectional shape that is connected shrinkage pool 11,21 are circular, oval, annular or shape such as square.The length L of connecting pin 3 is respectively greater than one of them D1, the D2 of the connection shrinkage pool 11,21 of correspondence, less than the connection shrinkage pool 11,21 of correspondence and, corresponding connection shrinkage pool 11,21 has wrapped up connecting pin 3 fully, and connecting pin 3 is excessively to cooperate or drive fit with being connected shrinkage pool 11,21
See also shown in Figure 2ly again, the member 4,5,6,7,8,9 of wood furniture connects by connecting pin 3 just can form special-shaped chair.
See also shown in Figure 3ly again, the member 41,51,61,71,81 of wood furniture connects by connecting pin 3 just can form Baby crib.
