Abstract

The utility model discloses a connecting structure for a cross rod and a vertical rod of solid wood furniture. The connecting structure comprises the cross rod and the vertical rod. One side face of the middle of the cross rod is provided with a tongue-and-groove. The tongue-and-groove is perpendicular to the length direction of the cross rod. A first slope surface is arranged on one side of the tongue-and-groove in an inclined cutting mode. The upper side face of the free end of the vertical rod is provided with a tenon matched with the tongue-and-groove. One sidewall of the tenon is provided with a second slope surface in an inclined cutting mode, wherein the second slope surface is matched with the first slope surface. The end face of the first slope surface is provided with a clamping hole. A clamping pin matched with the clamping hole is arranged on the second slope surface. According to the connecting structure, a set of locating assembly formed by the tenon and the tongue-and-groove and a set of locating assembly formed by the clamping hole and the clamping pin in a cross-shaped distributed mode are adopted, and the connecting structure is limited both in the vertical direction and the forward-backward direction. Consequently, the connecting structure can be effectively prevented from loosening, and the stability and reliability of the connecting structure are achieved.

Description

A kind of solid wood furniture bar linkage structure anyhow

Technical field

The utility model relates to solid wood furniture technical field, more specifically says a kind of solid wood furniture bar linkage structure anyhow.

Background technique

Chinese feature is all more popular recent years, wherein therefore solid wood furniture has also been subject to intimately pursuing, evaluate the quality of a mahogany furniture, be exactly primarily whether each joint of seeing it has used glue or nail, do not use glue or nail, its useful material be all also solid wood, that has been exactly solid wood furniture that part is top grade.

Each joint routine techniques of top grade solid wood furniture is all to adopt tenon and mortise to constitute, its core is interference fit, such as patent CN201110330747.X mentions, comprises a body and table leg, and both adopt feather joint.But, the wood furniture joint of this patented technology adopts single tenon connecting structure, service time one, length was easily rocked, the problem of structure less stable, and it does not arrange any structure to prevent that tenon from returning from mortise, As time goes on, can slowly get loose and come, the final disengaging damages.

Patent CN201220267331.8 has recorded a kind of mahogany furniture Tenon linkage structure, and it comprises two horizontal materials and a perpendicular material, and the connecting end of two described horizontal materials all arranges outer tenon and interior tenon, wherein: the interior tenon of two horizontal materials is that one is long and the other is short; Described perpendicular material is provided with the mortise of vertical perforation, this mortise, and wherein a mortise two is open-minded, and one of another mortise is opened a closure.Although this patented technology can solve the problem of single tenon connecting structure less stable of above-mentioned patent wood furniture joint, effectively strengthen the adhesive strength of joint, but it does not still arrange any structure to prevent that tenon from returning from mortise, As time goes on, and the shifting frequency of mahogany furniture, or can slowly get loose and come, the final disengaging damages.

Model utility content

The purpose of this utility model is to overcome the defect that in prior art mahogany furniture linkage structure, tenon can exit from mortise, provide a kind of simple in structure, convenient for production, assemble easy, reliable and stable, be difficult for the solid wood furniture bar linkage structure anyhow that gets loose, adaptation is good.

In order to reach above object, the utility model is achieved through the following technical solutions: a kind of solid wood furniture is bar linkage structure anyhow, comprise cross bar and montant, it is characterized in that, on described one side, cross bar middle part, offer a tongue-and-groove, the length direction of described tongue-and-groove and cross bar is perpendicular, and a side of described tongue-and-groove is provided with one first slope along cutting sth. askew; On described montant free end upper side, be provided with a tenon matching with described tongue-and-groove, on one side wall surface of described tenon, cut sth. askew and be provided with second slope matching with described the first slope, on the end face of described the first slope, be provided with a hole clipping, on described the second slope, be provided with a bayonet lock matching with described hole clipping.

The utility model adopts two groups of tenon and tongue-and-groove and hole clipping and bayonet locks to be the positioning component of cross distribution, spacing to all link being carried out at upward and downward and front and back, thereby can effectively prevent the problem of getting loose, and reaches reliable and stable object.

As preferably, in the interior sidewall surface of described tongue-and-groove, be vertically arranged with a draw pin, in the interior sidewall surface of described tenon, offer the chute matching with described draw pin, it is upper and lower that described chute longitudinally connects whole tenon.

Strengthen adhesive strength and the stability of joint, then add one group of draw pin and the next multiple location of chute.In addition, the utility model, for convenient processing, arranges the slope of an open draw pin in a side of tongue-and-groove, thereby conveniently in groove, processes a draw pin.The another one effect of slope is to make between two links adaptation good.

As preferably, in the interior sidewall surface of described tongue-and-groove, be longitudinally respectively arranged with a mortise, described draw pin is embedded in described mortise, and draw pin exposes outside mortise.

In order conveniently to process draw pin, the draw pin of outputing an one on cell wall is more difficult, and time-consuming, and therefore, the utility model, in order to reduce man-hour, is first opened a mortise, then adds a draw pin, and draw pin exposes outside mortise.

As preferably, on described montant, the below of tenon is provided with and caters to breach.

In order to increase the adaptation between cross bar and montant, so when montant is connected to cross bar and gets on, arrange and cater to breach below montant, to reach closely sealed.

As preferably, cross bar and montant are wood materials.

The basic demand of solid wood furniture, so material all needs to adopt wood materials, also only has utility furniture ability particular specification can not adopt the auxiliary materials such as glue and screw.

Beneficial effect: the utility model adopts two groups of tenon and tongue-and-groove and hole clipping and bayonet locks to be the positioning component of cross distribution, spacing to all link being carried out at upward and downward and front and back, thereby can effectively prevent the problem of getting loose, and reaches reliable and stable object.
