Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated, but the multitude of different ways that the utility model can be defined by the claims and cover is implemented.
Referring to Fig. 1 to Fig. 5, show preferred embodiment according to linkage structure of the present utility model, as shown in the figure, this linkage structure comprises: first link 1, the second link 2, retainer 3 and the unlock piece 4.
As can be seen from Figure, first link has attachment hole 11, the second links 2 and has connecting pin 21, and connecting pin 21 is fit to insert in the attachment hole 11, and connecting pin 21 is provided with locating slot 22.Retainer 3 is installed on first link 1, and has an elastic lock tongue 31 that stretches into attachment hole 11, like this, when connecting pin 21 inserts in the attachment hole 11, elastic lock tongue 31 can stretch, make connecting pin 21 continue in attachment hole 11, to move, in elastic lock tongue 31 snaps in locating slot 22, realize that first link 1 is connected with second the reliable of link 2.
Unlock piece 4 is installed on first link 1, be used to drive elastic lock tongue 31 axial motions, when needs are dismantled second link 2, only need operation unlock piece 4, make elastic lock tongue 31 axial motions from locating slot 22, to break away from, can realize the dismounting of first link 1 and second link 2 easily.With respect to the linkage structure of prior art, have simple in structure, easy to operate advantage according to linkage structure of the present utility model, and greatly saved the dismounting time, improved dismounting efficient.
In conjunction with reference to figure 1, Fig. 2 and Fig. 3, show a kind of preferred structure according to retainer 3 of the present utility model, this retainer 3 is installed in first mounting hole 13 of first link 1, retainer 3 also comprises the backstop bolt 32 that is spirally connected with first mounting hole 13, and be installed in spring 33 between backstop bolt 32 and the elastic lock tongue 31, make that elastic lock tongue 31 can be flexible along first mounting hole, 13 directions, be convenient to connecting pin 21 and insert in the attachment holes 11 or from attachment hole 11, extract.Preferably, the end 311 tapered or angular surface type that match with locating slot 22 of elastic lock tongue 31.Like this, insert in attachment hole 11 processes at connecting pin 21, connecting pin 21 is pressed on the conical surface or inclined-plane of elastic lock tongue end 311, can be easy to order about elastic lock tongue 31 and shrink along first mounting hole 13, and connecting pin 21 not produced bigger installation resistance.
In conjunction with reference to figure 1, Fig. 4 and Fig. 5, show a kind of preferred implementation of unlock piece 4, unlock piece 4 is installed in second mounting hole of offering on first link 1 15, and elastic lock tongue 31 is provided with shrinkage pool 312, for example is rectangular opening.Unlock piece 4 comprises can axially movable return pin 41, and return pin 41 is passed shrinkage pool 312, and return pin 41 is concave structure 42 towards a side of spring 33.Preferably, return pin 41 is perpendicular with elastic lock tongue 31, and this concave structure 42 is the concave arc shape structure.When elastic lock tongue 31 snaps in locating slot 22, shrinkage pool 312 is corresponding to the middle part of concave arc shape structure, when needs when first link 1 is removed second link 2, only need to promote return pin 41, the concave arc shape structure compresses the hole wall of this shrinkage pool 312, impel elastic lock tongue 31 to shrink, make elastic lock tongue 31 break away from locating slot 22 at an easy rate.Preferably, in the shrinkage pool 312 of elastic lock tongue 31 roller 313 is installed also, roller 313 compresses with concave structure 42, and it is more laborsaving to operate return pin 41 like this.Certainly, above-mentioned concave structure 42 can also have other mode of executions, and for example in a kind of unshowned mode, this concave structure 42 is the angular surface type structure, can drive the contraction of elastic lock tongue 31 equally.As can be seen from Figure,, obviously, have enough gap L between shrinkage pool and the return pin 41 from the shrinkage pool 312 of elastic lock tongue 31, avoid elastic lock tongue 31 operations to be obstructed because of return pin 41 is passed.
As can be seen from Figure, first end 411 of return pin 41 is the operating end, by the contraction of pressing operation end 411 and then control elastic lock tongue 31.In the position, aperture of second mounting hole, 15 corresponding return pin 41 first ends guard ring 5 is installed also in the present embodiment, to prevent misoperation to return pin 41.Preferably, guard ring 5 is connected on first link 1, so that install.
Preferably, in the present embodiment, resetting of return pin 41 is to implement in the following way, at second end 412 of return pin 41 guide sleeve 43 is installed, and this guide sleeve 43 is positioned at second mounting hole 15.Second end 412 of return pin 41 passes the back from guide sleeve 43 and is spirally connected with stop nut 46, like this, when dismounting second link 2, push the operating end 411 of return pin, elastic lock tongue 31 breaks away from the clamping matching relationship with locating slot 22, after connecting pin 21 breaks away from attachment hole 11, unclamp pushing to return pin 41, this moment, elastic lock tongue 31 stretched out in attachment hole 11 under the effect of spring 33, roller 313 and concave arc shape structure 42 self adaptions, impel return pin 41 to automatically reset, and under the effect of stop nut 46, return pin 41 is in the corresponding nature of its concave structure middle part and shrinkage pool 312.Between guide sleeve 43 and stop nut 46, spring washer 47 can also be set.Need to prove, make return pin 41 automatically reset modes a variety of, for example can also adopt elastic reset structure etc.
The above is a preferred embodiment of the present utility model only, is not limited to the utility model, and for a person skilled in the art, the utility model can have various changes and variation.All within spirit of the present utility model and principle, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
