Description

A kind of link

Technical field

The present invention relates to a kind of link, refer in particular to a kind of link that is used to have the material product of inside groove.

Background technique

The hardware fitting of furniture mainly contains the form of bolt and nut and three-in-one link at present, and wherein bolt and nut is disguised bad, and three-in-one link generally is used for composite sheet (as: density board, shaving board etc.), and wants first embedded nut, and stressed little.Metal frame such as iron and steel builds to be welded as the master in the building materials.The lifting frame of the frame of technology kind picture frame capable of being combined and desk lamp etc., the bolt fastener that is adopted, its force bearing point are the bolt top, and discontinuity.

Summary of the invention

The technical problem that the present invention will solve provides a kind of corresponding inside groove that has been applicable to; Link like the timber of trapezoidal inside groove, square inside groove, circular inner groove etc., metal, stone material, plastic or other material goods; Not only connection can be installed directly, and dismounting is simple and convenient, reusable.

In order to solve the problems of the technologies described above, technological scheme proposed by the invention is: a kind of link, comprise frame, fastening piece, and it is characterized in that: said frame is flexible frame, and described frame has a stationary plane, bi-side and a bottom surface; Described stationary plane has at least one fastener hole, said fastening piece at least one.

Further, described bi-side are plane or cambered surface, to be suitable for difform groove.

Further, described bottom surface is curvilinear plane, broken line face or arc surface, and the bottom surface overall width is more than or equal to the stationary plane width.

Further, described bottom surface is made up of the bottom surface, two oblique angles that bends inwards, and bottom surface, oblique angle overall width is more than or equal to the stationary plane width.

Further, when described oblique angle bottom width equaled the stationary plane width, the joint of preferred bottom surface, described oblique angle and bi-side was provided with lug.

Further, the stationary plane both sides of described link are provided with draw-in groove, and bi-side are connected fixing with the draw-in groove interference fit of stationary plane.

Further, between the stationary plane of described link and the bi-side, adopt articulated manner to be connected between bi-side and the bottom surface.

Further, also comprise sheet strip catch, described strip catch places top, bottom surface, oblique angle, when fastening piece is fastening, makes the bottom surface, oblique angle stressed evenly.

Preferably, described bi-side are the plane.

Preferably, said catch is the sheet strip that there is tooth mouth nail flat plate strip or both sides.

Preferably, said fastening piece is screw or bolt, and described fastener hole is screw hole or bolt hole.

The present invention also comprises a kind of link, comprise at least two weld together, the one-body molded or above-mentioned link through the arbitrarily angled connection of link.

After adopting such structure, the link that it is made can be used for having corresponding inside groove, and splicing and combining of the various materials of preferred dovetail groove played the fixing effect of connection, thereby had wide range of applications, and relates to materials such as timber, stone material, plastics, metal.Because it is it is bigger with the surface of contact of article of being fixed, stressed relatively more balanced again, thus be not easy to make the article distortion that is fixed impaired, and this structure dismounting is flexible, good concealment.

Embodiment

Below in conjunction with accompanying drawing and embodiment, the present invention is further specified.

The bottom surface of the frame of Fig. 1 in the link shown in Figure 4 is the various embodiments of bottom surface, two inclined-planes, arc surface, curvilinear plane, broken line face.

Be provided with lug in the joint of bottom surface, oblique angle and bi-side in the link shown in Figure 5, when being used for the oblique angle bottom width and equaling the stationary plane width, in inside groove, establish groove, supply lug fastening.

The bi-side of the frame in the link shown in Figure 6 are the embodiment of arc surface.

Adopt hinged schematic representation between the bottom surface and side of the frame in the link shown in Figure 7, between side and the bottom surface.

The stationary plane of the frame in the link shown in Figure 8 is provided with draw-in groove, adopts interference fit to be fixedly connected between bi-side and the stationary plane.

Fig. 1, link shown in Figure 9 are made up of frame 1, catch 2, fastening piece 3; Said frame 1 is flexible frame, and described frame has a stationary plane 10, bi-side 12 and bottom surface 11, and described bottom surface is to have the inclined-plane that bends inwards; Described bottom surface 11 overall widths are more than or equal to the stationary plane width; Said catch 2 is the sheet strip structure that there is tooth mouth nail flat plate strip or both sides, and described stationary plane 10 has at least one fastener hole, and said fastening piece 3 uses one at least; Said fastener hole can be screw hole or bolt hole, and fastening piece 3 can be screw or bolt.When fastening piece 3 is screwed with frame 1; Fastening piece 3 roof pressure catch 2; Catch 2 extends out at the bi-side 12 of frame 1 two bottom surfaces 11 of frame 1 to extrapolation simultaneously, makes two bottom surfaces 11 of link form outward expansion force simultaneously with bi-side 12, thereby link and inside groove are combined closely.

Two links that link vertically connects to form shown in Figure 9; Two links can weld or be one-body molded or through the arbitrarily angled connection of link; After the link that vertically connects to form being placed in inside groove such as the trapezoidal inside groove of required article; Screw earlier on one side fastening piece 3 and frame 1, fastening piece 3 roof pressure catch 2, catch 2 extends out at the bi-side 12 of frame 1 two bottom surfaces 11 of frame 1 to extrapolation simultaneously; Make two bottom surfaces 11 of link form outward expansion force simultaneously, thereby link and trapezoidal inside groove are combined closely with bi-side 12.By the screw link of opposite side of same method, the link that two links are vertically connected to form fastening fully with article on.

The trapezoidal inside groove of lifting frame that is used for shown in Figure 10; The lift side that link connects lifting frame also places in the dovetail groove of lifting frame, regulates the degree of tightness of fastening piece 3, selects behind the suitable position fastening piece 3 and frame 1 to screw; Fastening piece 3 roof pressure catch 2; Catch 2 extends out at the bi-side 12 of frame 1 two bottom surfaces 11 of frame 1 to extrapolation simultaneously, makes two bottom surfaces 11 of link form outward expansion force simultaneously with bi-side 12, thereby link and trapezoidal inside groove are combined closely.

Both sides shown in Figure 11 have the catch 2 of the sheet strip structure of tooth mouth nail generally to be used for wood products, strengthen steadiness.

Although specifically show and introduced the present invention in conjunction with preferred embodiment; But the those skilled in the art should be understood that; In the spirit and scope of the present invention that do not break away from appended claims and limited; In form with on the details the present invention is made various variations, be protection scope of the present invention.
