Description
Technical field
The present invention relates to technical field of furniture, be specifically related to a kind of furniture connection fittings.
Background technique
At present, furniture connection fittings, its structure and a great variety of models, for the connection fittings on existing chair, connection fittings are the oval pedestal that metallic material is made, and it comprises installs end face and sidewall thereof, and installation end face and side are Integratively formed and are arc transition between them; During use, generally need the connection fittings described in two pieces and the intermediate connector for being connected by two pieces of connection fittings, two pieces of connection fittings are fixed on chair both sides corresponding position, and the two ends of intermediate connector are welded and fixed by welding manner and both sides connection fittings; The connection fittings of said structure, have the following disadvantages: (1) welding procedure General Requirements is higher, workman need possess skilled welding technical ability, and welding expends time in longer, both work task efficiency had been affected, cause the manufacturing efficiency of chair lower, and high temperature, high light and some toxic gases in welding process, can be produced, certain infringement can be had to workman; (2), during welding, easily because of welding procedure difference, cause and weld undesirable between accessory or weld not in place, even affect the soundness connected between accessory; Further, unsightly for eliminating weld between accessory, need to process weld toward contact, cause the increase of processing technology, thus too increase cost of production; And because most welding method all adopts local heating, the weldment after welding, inevitably can produce certain welding stress and distortion in the structure, thus affects the bearing capacity of structure, machining accuracy and dimensional stability etc.; Meanwhile, stress also can be caused to concentrate at weld seam and weldment intersection, easily cause the brittle fracture of structure.The defect of some is easily there is in welded joint, as crackle, pore, slag inclusion, lack of penetration, incomplete fusion etc., the existence of these defects, the intensity of joint can be reduced, cause stress to concentrate, damage weld seam compactness, be destroy welded one of the main reasons, finally can cause that whole chair frame entirety is insecure, intensity is low.(3) the accessory weld on furniture item, can leave soldering, affect the overall appearance of chair, and face of weld is unsmooth, and it is bad that people touches feel.
In view of above all deficiencies, existing furniture industry is badly in need of making improvements connection fittings, can ensure " soundness of connection ", can realize again connecting cooperation fast, and technique is simple and easy, do not affect product requirement attractive in appearance to meet.
Summary of the invention
The object of the invention is to the deficiency overcoming the existence of above-mentioned prior art, and provide a kind of connection to coordinate quick, simple and easy, and can ensure the soundness of connection greatly to improve the furniture connection fittings of its production effect.
The object of the present invention is achieved like this:
Furniture connection fittings, connection fittings comprise installs end face and sidewall thereof, installation end face and side are Integratively formed and are arc transition between them, it is characterized in that, the both sides of described installation end face respectively have mounting hole, installation end face between the mounting hole of both sides also has patchhole, and patchhole extends to sidewall by installing end face; These kind of furniture connection fittings, patchhole is set up by the centre of the mounting hole in connection fittings both sides, utilize patchhole as the fixing use of intermediate connector grafting, overcome in prior art, need all deficiencies of welding, make it connect cooperation quick, simple and easy, and the soundness of connection can be ensured, greatly improve its production effect etc.
The present invention can also do following further improvement.
As preferred scheme, the mounting hole of described installation end face both sides is heavy stand holes; The design in heavy stand hole, the sinking being conducive to screw is fixed, thus improves the soundness of screw connection.
As scheme more specifically, the heavy stand with holes that end face both sides are provided with concave shape is installed in described heavy stand hole, and heavy stand with holes is wide at the top and narrow at the bottom and the bottommost of heavy stand is provided with circular hole.
Described patchhole ovalize; Be conducive to the insertion of intermediate connector.
As scheme concrete further, described connection fittings are oval metalwares, and oval patchhole two ends extend to the mounting hole close to both sides.
The patchhole of above-mentioned ellipse, its width direction one end extends to sidewall, and the other end stretches to the degree of depth being greater than mounting hole close to the height of sidewall described in the other end edge installing end face.
Beneficial effect of the present invention is as follows:
(1) furniture connection fittings of the present invention, patchhole is set up by the centre of the mounting hole in connection fittings both sides, utilize patchhole as the fixing use of intermediate connector grafting, overcome in prior art, need all deficiencies of welding, make it connect cooperation quick, simple and easy, and the soundness of connection can be ensured, greatly improve its production effect etc.
(2) have again, the connection fittings of this furniture, in view of easy to connect, easy, consuming time short, be connected firmly, so, employ this connection fittings, its join strength, but also convenient mounting or dismounting were not only improved, effectively improve production efficiency of assembling and the assembly precision of furniture, and the mechanical strength properties etc. of furniture entirety, there is good interchangeability and be suitable for mass production.
(3) more have plenty of, this connection fittings, its dismounting is simple and easy, facilitates transport, effectively reduces the packaging volume of furniture, thus reduces cost of transportation.
Accompanying drawing explanation
Fig. 1 is the structural representation of furniture connection fittings of the present invention.
Fig. 2 is the mode of execution schematic diagram of furniture connection fittings of the present invention.
Embodiment
Below in conjunction with drawings and Examples, the invention will be further described.
See shown in Fig. 1 to Fig. 2, a kind of furniture connection fittings, connection fittings 1 are oval metalware, it comprises installs end face 14 and sidewall 13 thereof, installation end face 14 and sidewall 13 are Integratively formed and are arc transition 4 between them, it is characterized in that, the both sides of described installation end face 14 respectively have mounting hole 11, mounting hole 11 is heavy stand holes, its embodiment is: the heavy stand with holes that end face 14 both sides are provided with concave shape is installed in heavy stand hole, and heavy stand with holes is that bottommost that is wide at the top and narrow at the bottom and heavy stand 141 is provided with circular hole; Installation end face 14 between the both sides mounting hole 11 of described connection fittings 1 also has oval patchhole 12, patchhole 12 extends to sidewall 13 by installation end face 14, oval patchhole 12 presses length direction, its two ends extend to the mounting hole 11 close to both sides, by width direction: one end extends to sidewall 13, the other end stretches to the other end edge close to installation end face 14.
