Abstract

The utility model relates to a furniture joint, which is a long column, a plurality of conoid process rings 11 are continuously arranged on both ends of the long column, a slant ring groove is in the connection of two conoid process rings, a shoulder 13 is in lateral process, and a plurality of axial grooves, which are arranged around the joint and communicated with both ends of the joint, are vertical to the conoid process rings 11. When the joint is inserted into the spliced eye of the wood, the wood dust in the spliced eye falls into the axial grooves, sealing the yawn between the wood together, preventing the rotating generated between the joint and the wood, and effectively increasing the closed degree between the wood and the stability of assembling.

Description

A kind of furniture connection

The utility model relates to a kind of joint of furniture, refers to a kind of in order to increase the chimeric stability of timber and the joint of adaptation especially.

Press, timber is the material of article of furniture consumption maximum, such as tea table, closet, cabinet are all made with timber, even the also bound wooden base of leather sofa, for asking the attractive in appearance of furniture finished product appearance, general neither use metal nail in the winding of timber and adopt built-in joint is not so that the outward appearance of furniture has the nail trace, is integrity; And the joint of preceding use generally as shown in Figure 1, this joint 1 is that long column body two end part are provided with several conoid process rings 11 respectively and are provided with continuously, form the shoulder 13 of an oblique annular groove 12 and a horizontal projection in two conoid process rings, 11 connecting places, usage mode is respectively to dig prior to timber 2 places that desire engages to establish the spliced eye 21 of an aperture less than joint 1 maximum outside diameter, the degree of depth that makes this spliced eye 21 just is 1/2nd of the length of joint 1, inferior conoid process ring 11 with joint 1 two ends compels to fill in the spliced eye 21 of timber 2 respectively, as shown in Figure 2, because the aperture of spliced eye 21 is less, cause conoid process ring 11 tight the plugs wherein at joint 1 two ends, more utilize timber 2 itself to omit the flexible characteristic of tool and in the oblique annular groove 12 of joint 1, form a flange 22, clip is in shoulder 13, and makes timber 2 unlikely delamination.

The above-mentioned product of commonly using can be big with the aperture support of spliced eye 21 when the conoid process ring 11 of joint 1 is in the spliced eye 21 that is forced into timber 2, cause hole wall how much to have peeling off of tiny wood chip 3, and owing to conoid process ring 11 continues to be forced into, then wood chip 3 will be pushed in the hand-hole, joint 1 can't be inserted into spliced eye 21 end to the greatest extent fully, the influence that remained by wood chip 3 also makes 2 in timber retain a gap 4, and is shown in Figure 2 with ginseng.

The purpose of this utility model is that a kind of joint structure of wood furniture is being provided, and makes it can effectively solve the problem that the product of commonly using easily cause the gap to produce, and the adaptation of timber is improved, and promotes the timber combination stability simultaneously.

For achieving the above object, the utility model is a long column body, two ends have some conoid process rings to be provided with continuously respectively, form the shoulder of an oblique annular groove and a horizontal projection in two conoid process ring connecting places, ring in joint encloses some axial notches, and these some grooves are to connect the joint two ends and become vertical configuration with the conoid process ring.

After adopting said structure, it has the stability of better adaptation and combination.

The utility model is described in further detail below in conjunction with drawings and Examples.

Fig. 2 is a use schematic representation of commonly using product

Fig. 3 is a stereogram of the present utility model

Fig. 4 is a use schematic representation of the present utility model

Fig. 5 is A of the present utility model-A sectional view

See also Fig. 3, the utility model is a joint 1, these joint 1 two ends have some conoid process rings 11 to be provided with continuously respectively, make the tip towards two ends, encircle the shoulder 13 that 11 connecting places form an oblique annular groove 12 and a horizontal projection in two conulis, ring in joint 1 encloses some axial notches 14, make some axial notches 14 connect joint 1 two ends and with 11 one-tenth vertical configurations of conoid process ring.

Consult Fig. 4, establish the spliced eye 21 that the degree of depth is about joint 1/1st two length prior to digging on the timber 2 together during use, and make the aperture be slightly less than the maximum diameter of conoid process ring 11, inferior two end part with joint 1 are forced into respectively in the spliced eye 21 of timber 2, at this moment, because conoid process ring 11 is forced into by force, make the hole wall of spliced eye 21 produce tiny wood chip 3, then fall in the axial notch 14 one after another, thus, spliced eye 21 bosoms just can be stretched into really in joint 1 end, and 2 in timber also can reach driving fit, gapless purpose.

Moreover, after the utility model compels to fill in the spliced eye 21 of timber 2, timber 2 formed flange 22 in oblique annular groove 12 can prevent joint 1 extraction (seeing shown in Figure 4), simultaneously, also can form a flange 22 ' in the axial notch 14 to prevent the rotation of 2 in joint 1 or timber, as shown in Figure 5, mat it, can effectively increase the stability of timber 2 combinations.

Claims (1)

1. A kind of joint of furniture, this joint is a long column body, two ends have some conoid process rings to be provided with continuously respectively, form the shoulder of oblique annular groove one a horizontal projection in two conoid process ring connecting places, it is characterized in that: the ring of joint encloses some axial notches, and these some axial notches are to connect the joint two ends and become vertical configuration with the conoid process ring.
