Detailed description of the invention
Detailed description of the invention of the present utility model is described in detail below in conjunction with accompanying drawing 1-2 and preferred embodiment.
A kind of electric bicycle fame stone tongs, for lifting the pipe fitting 6,7 of Electrical Bicycle, comprise suspension hook 1, digonal link 2 and lifting body 4, the quantity of described digonal link 2 is two, described lifting body 4 comprises two hold assemblies 41,42, described each hold assembly includes segmental arc 41 and arc gripping section 42, described suspension hook 1 is connected by suspension hook pin 5 with the upper end of two described oblique 2 pull bars, the described lower end of two described digonal links 2 with the upper segmental arc 41 of described hold assembly for pin is connected; Described two hold assemblies 41,42 are connected to form class " X " shape by swivel pin 3, when suspension hook 1 bears gravity, the angle that described two digonal links 2 are formed diminishes, described two digonal links 2 drive the arc gripping section 42 of described hold assembly to close up by described upper segmental arc 41, and clamp outer tube 6.
The utility model, by the pin joint mode of suspension hook 1, digonal link 2, " X " type lifting body 4 three parts, is pulled the change of digonal link 2 angle, thus drives arc gripping section 42 to close up by upper segmental arc 41, and clamp outer tube 6 by suspension hook 1; This Tool clamp structure is simple, efficient and convenient, it is solid and reliable to lift, and improves the production efficiency that Electrical Bicycle needs the link lifting bicycle frame pipe in process of production.
The angular range that described two digonal links 2 are formed is 60 degree of-170 degree, and the length of each digonal link 2 is 15-30cm.
Two digonal links are isometric, and the scope that arranges is 15-30cm, and it is 60 degree of-170 degree that prompting limits the angular range formed, digonal link like this is by the above-mentioned design of length and angle, can control the variation range clamping pipe fitting, from the pipe fitting being applicable to different tube diameters, comformability strengthens.
The arc gripping section 42 of described hold assembly closes up rear formation similar round shape, and the lower end of the arc gripping section 42 of described hold assembly is provided with those widened sections 421.
The lower end of the arc gripping section 42 of described hold assembly is also provided with and extends gripping section 43, and described extension gripping section 43 closes up rear formation toroidal or elliptical shape or triangle, and the lower end of described extension gripping section 43 is provided with and extends those widened sections 431.
Extend the lower end that gripping section 43 is arranged on arc gripping section 42, and clamping is closed up rear toroidal or elliptical shape or triangle and is convenient to lift multiple pipe fitting (if having special pipe fitting or other similar shafts to need lifting at production process from now on simultaneously, then can select above-mentioned design).Not only enhance productivity, also enhance the application of frock;
And the lower end of arc gripping section 42 and extension gripping section 34 is provided with those widened sections 421,431, increases the frictional area with outer tube 6,7, ensures the safety of lifting.
The arc gripping section 42 of described extension gripping section 43 and described hold assembly is for being rigidly connected or active link.When the two is for being rigidly connected, ensure that the intensity of lifting body; When the two is flexibly connected, is conducive to the convenient of different operation and replaces, make this frock one-object-many-purposes.
Described extension gripping section 43 is also provided with elastic protection layer 8 with the junction of described arc gripping section 42.
The design of elastic protection layer 8, not only by elastomeric elastic force effect, draw bare terminal over to one's side, play the effect of strengthening arc-shaped gripping section Clamping force, simultaneously also can intercept or reduce the skimming wear between the first pipe fitting 6 and the second pipe fitting 7.
The clamping range (i.e. the first pipe fitting 6) of arc gripping section 42 formation of described hold assembly is less than the clamping range (the second pipe fitting 7) of described extension gripping section 43 formation.Such design, clamp Large Diameter Pipeline below, and clamp pipe with small pipe diameter above, be convenient to design, conveniently assemble and disassemble, ensure that safe in operation.
The above is only preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
