Embodiment

With reference to Fig. 1 and Fig. 8, the rod member linkage structure comprises rod member 1 and the fastener that is connected with rod member 1, and said fastener is provided with rod member snapping portion, and rod member snapping portion is the ring buckle 2 that matches with rod member 1 outer wall, and ring buckle 2 is provided with bayonet socket 21 vertically; Ring buckle 2 be one the aperture pitch of bayonet socket 21 is changed elastic component; Ring buckle 2 cooperates the maximum radial distance of the aperture pitch of back bayonet socket 21 less than rod member 1 with rod member 1; The inwall of ring buckle 2 is provided with protuberance 22, and outer wall is provided with recess 11 on the corresponding rod member 1, cooperates back protuberance 22 to cooperate with recess 11 and makes ring buckle 2 fixing with rod member 1; The outer wall of said ring buckle 2 is provided with the die cavity 3 with other object assemblings.Ring buckle 2 cooperates with rod member 1 outer wall; Wherein the setting of bayonet socket 21 is to be entered in the ring buckle 2 by bayonet socket 21 places for the ease of rod member 1; And then cooperate with the recess 11 of rod member 1 through the protuberance 22 of ring buckle 2; Thereby can realize that ring buckle 2 fixes along rod member 1 axial position, promptly ring buckle 2 can not endwisely slip along rod member 1.Ring buckle 2 is simple in structure, but once-through, need not to use other accessories can accomplish with rod member 1 be connected and connect reliable and stable, assembling is simple and be easy to dismounting, is applicable to the connection assembly unit of various support bodys in the haberdashery and hardware widely.Ring buckle 2 generally can adopt the plastics integrated injection molding or have certain elastic deformability's metal machine shaping, selects for use the plastic production cost cheap relatively and technology is simple certainly.

Wherein protuberance 22 can adopt multiple structural type to realize that the utility model provides two kinds of embodiments for reference with recess 11.Referring to figs. 1 through Fig. 5, first kind is that said protuberance 22 is at least one salient point that is arranged at ring buckle 2 inwalls, and the recess 11 of rod member 1 is the perforation that cooperates with salient point.Certainly in actual use need be according to connecting the mode that fixing and stable requirement use a plurality of salient points to cooperate with a plurality of perforation; Like two salient points that are provided with in ring buckle 2 inwalls symmetry; Then on rod member 1 also symmetry be provided with two perforation; Just very firm and stable behind ring buckle 2 and rod member 1 snapping so, with reference to Fig. 1, Fig. 2 and Fig. 4; In order to prevent that further salient point breaks away from from recess, the end of salient point is provided with barb, with reference to Fig. 5.With reference to Fig. 6, second kind is the convex tendon of said protuberance 22 for being provided with along ring buckle 2 inwalls, and the recess 11 of rod member 1 is the circular groove that cooperates with convex tendon; In general circular groove forms through roll extrusion; Therefore the degree of depth is more shallow, and because annular port is an elastic component, even under the effect of less axial force; Convex tendon also is easy to from circular groove, break away from, so this structure only is applicable to that stressed less support body uses.

For elastic component two kinds of structural types can be arranged, a kind of is not receive under the external force situation, and the internal diameter of ring buckle 2 is less than or equal to the diameter of rod member 1; With reference to Fig. 1, Fig. 3 and Fig. 5; When the needs snapping, firmly bayonet socket 21 is broken into two with one's hands, rapidly rod member 1 is snapped onto in the ring buckle 2 then; Unclamp back bayonet socket 21 spacings and recover, rod member 1 can not have bayonet socket 21 places to break away from easily.This structure is broken into two with one's hands for the ease of bayonet socket 21, and said bayonet socket 21 is provided with flange 23, with reference to Fig. 3 and Fig. 5.A kind of in addition is not receive under the external force situation, and the internal diameter of ring buckle 2 is more than or equal to the diameter of rod member 1, with reference to Fig. 2, Fig. 4 and Fig. 8; When the needs snapping, firmly bayonet socket 21 is broken into two with one's hands equally, rapidly rod member 1 is snapped onto in the ring buckle 2 then; Unclamp back bayonet socket 21 spacings and recover, rod member 1 can not have the disengaging of bayonet socket 21 places easily, and still the protuberance 22 of ring buckle 2 does not assemble with the recess 11 of rod member 1 is sufficient at this moment; Need to cooperate with die cavity 3 through other accessories; Make ring buckle 2 produce distortion, thereby the internal diameter that dwindles ring buckle 2 assembles the protuberance 22 of ring buckle 2 and the recess 11 of rod member 1 fully, finally could ring buckle 2 is fine fixing with rod member 1.

Certainly be connected fixingly with rod member 1 through ring buckle 2 for the ease of other objects, the outer wall of said ring buckle 2 is provided with the die cavity 3 with the assembling of other objects.According to different use needs, the structure of die cavity 3 also can be different.Need be connected with pipe fitting like ring buckle 2, die cavity 3 is one can carry out the cylinder of socket with pipe fitting so, and is convenient and swift as long as pipe fitting and cylinder are pegged graft, with reference to Fig. 1 and Fig. 7.Need to be connected like ring buckle 2 with the wire accessory; Following several kinds of forms can be arranged so: die cavity 3 is boss; Outer wall along boss is provided with circular groove; The trip ring that the line body bends to the band opening is inserted into circular groove then and get final product, and certain this structure still is applicable to is with the tabular plug connector of opening to be connected with boss, with reference to Fig. 6; Die cavity 3 can also be with the attachment post of spliced eye at least one that is provided with vertically; The line body directly inserts spliced eye and fixes; With reference to Fig. 3,, can also on attachment post, be provided with locating slot so if do not hope to rotate after the line body inserts spliced eye; Locating slot and spliced eye intersect, and just can prevent to rotate except the external line body that forms an angle with it in addition of line that inserts spliced eye snaps in locating slot.

And to the internal diameter of ring buckle 2 under the said situation that do not stress above the using structure more than or equal to the diameter of rod member 1; The structure of the general employing interference fit of die cavity 3 is so that can make the buckle of ring buckle 2 tighten up; Like die cavity 3 can be the button of band opening; With reference to Fig. 2 and Fig. 8, and button be less than with the object of its assembling, object is clamp-oned button can make the buckle of annular port tighten up.Die cavity 3 can also be the attachment post of two band spliced eyes, and the distance between the spliced eye when two line bodies insert corresponding spliced eye respectively, also can make the buckle of annular port tighten up, with reference to Fig. 4 less than two distances with the line body of spliced eye grafting.

For the ease of connect using the inventor to design a kind of connecting-rod body 5 on the basis of the above, connecting-rod body 5 two ends are respectively equipped with the ring buckle 2 that is connected with rod member, also are provided with at least one in the connecting-rod body and are used for the spliced eye 4 that is connected with other rod members, with reference to Fig. 9.
