Abstract
The utility model relates to a wood furniture connecting structure, in particular to an arc crooked material connecting structure, which comprises two round transverse materials with the same outer diameter, and is characterized in that the connecting end of the first round transverse material has an upper arc shape; the top of the connecting end is provided with a first tenon, and the root of the connecting end is provided with a first mortise; the inner side of the connecting end between the first tenon and the first mortise is provided with a groove; the connecting end of the second round transverse material has a lower arc shape; the top of the connecting end is provided with a second tenon, and the root of the connecting end is provided with a second mortise; the inner side of the connecting end between the second tenon and the second mortise is provided with a groove; and a wedge nail is arranged. The utility model mainly solves the problem that the connecting strength of transverse materials is insufficient to cause looseness or too much glue is used to influence product quality in the conventional arc crooked material connecting structure for woof furniture.
Description
Technical field
The utility model relates to the wood furniture linkage structure, particularly a kind of curved bend material linkage structure.
Background technique
As everyone knows, curved bend material linkage structure mainly adopts the linkage structure of tongue-and-groove in the existing wood furniture, namely the connecting end surface at horizontal material has slot, the connecting end processing tenon of another horizontal material, during installation the tenon insertion slot of horizontal material can be finished joint, because its shape is arc, therefore is also referred to as and is curved bend material linkage structure.This linkage structure generally is used on the handrail of round-backed armchair etc., because stressedly generally all will add glue not, does not perhaps have the wedge nail to cause connection part unstable with half dowel construction, the problem such as easily becomes flexible.
The model utility content
The purpose of this utility model is to provide a kind of curved bend material linkage structure, mainly solves in the curved bend material linkage structure of existing wood furniture, and the join strength of horizontal material often causes not loosening or used too many glue to affect the problem of quality of product.
For achieving the above object, the utility model is to realize like this.
A kind of curved bend material linkage structure, it comprises that two have the circular horizontal material of same outer diameter as, it is characterized in that: the connecting end of described the first circular horizontal material is the upper semi-circle arc shape, this connecting end top has the first tenon, the root of this connecting end has the first mortise, and the connecting end inboard between this first tenon and the first mortise has a groove; The described second circular horizontal material connecting end is the lower semi-circle arc shape, and this connecting end top has the second tenon, and the root of this connecting end has the second mortise, and the connecting end inboard between this second tenon and the second mortise also has a groove; Also has wedge nail.
Described curved bend material linkage structure is characterized in that: the second mortise and second tenon of the first tenon of described the first circular horizontal material and the first mortise and the second circular horizontal material are pegged graft mutually; And the groove of two horizontal materials is combined into a slot, and described wedge nail inserts in this slot.
Described curved bend material linkage structure, it is characterized in that: described tenon and mortise all are arranged on the centre of circular horizontal material.
Described curved bend material linkage structure is characterized in that: the thickness of described tenon is 1/5 of circular horizontal material external diameter.
Described curved bend material linkage structure is characterized in that: the length of described connecting end is 1/4 of circular horizontal material length.
By said structure also compared with prior art, the utility model has the advantage of: the utility model mainly solves the too little problem that causes vertical stressed easy disconnection of junction surface of the curved bend material linkage structure of existing wood furniture, avoided the lateral stressed problem of easily pulling open, made the connection of curved bend material more firmly with attractive in appearance.
The utility model structure can be used as the handrail of round-backed armchair, the aspects such as connection of bending accessory.

Embodiment
See also Fig. 1-3, the utility model discloses a kind of curved bend material linkage structure.As shown in the figure: it comprises that two have the circular horizontal material 1,2 of same outer diameter as, the connecting end of the described first circular horizontal material 1 is the upper semi-circle arc shape, this connecting end top has the first tenon 11, the root of this connecting end has the first mortise 12, and the connecting end inboard between this first tenon and the first mortise has a groove 13; The described second circular horizontal material 2 connecting ends are the lower semi-circle arc shape, and this connecting end top has the second tenon 21, and the root of this connecting end has the second mortise 12, and the connecting end inboard between this second tenon and the second mortise also has a groove 23; Also has wedge nail 3.
As a kind of preferred structure, described tenon and mortise all are arranged on the centre of circular horizontal material.
See also Fig. 4, during the utility model assembly and connection, the second mortise 22 and second tenon 21 of the first tenon 11 of the described first circular horizontal material 1 and the first mortise 12 and the second circular horizontal material 2 are pegged graft mutually; And two horizontal materials 1,2 groove 13,23 are combined into a slot, and described wedge nail 3 inserts in these slots.
As a kind of preferred parameter, described tenon 11,21 thickness are 1/5 of circular horizontal material external diameter.
As a kind of preferred parameter, the length of described connecting end is 1/4 of circular horizontal material length.
Being preferred embodiment of the present utility model only in sum, is not to limit practical range of the present utility model.Be that all equivalences of doing according to the content of the utility model claim change and modification, all should be technology category of the present utility model.
