Abstract
An elastic clamping ring device provided with an inner speed change chain ring and used for a shaft comprises an inner speed change element and an elastic clamping ring and further comprises a hollow conical body and a cylinder, wherein the cylinder is formed by two segments of hollow structures with one segment as the deep end and the other segment as the shallow end. The hollow conical body is placed in a shaft of the inner speed change element, and the hollow conical body is sleeved with the elastic clamping ring. The shallow end of the cylinder is placed into the hollow conical body first in a sleeved mode, so that the elastic clamping ring is half clamped to the hollow conical body in parallel, and the deep end of the cylinder is then placed in the hollow conical body in a sleeved mode, so that the elastic clamping ring is clamped into an inner speed change chain ring clamping groove along the hollow conical body. The elastic clamping ring device is simple in structure, and the elastic clamping ring used for the shaft can be installed easily and fast.
Description
Affiliated technical field:
The utility model relates to the simple and quick axle that internal speed-changing gear piece is installed the easily elastic collar device in a kind of mounting tools field of bicycle, particularly a kind of energy.
Background technology:
Bicycle and Electrical Bicycle, as a kind of vehicle, are used widely by people.For the attractive in appearance and people's of car demand, on some bicycle and Electrical Bicycle, can use internal speed-changing.
When internal speed-changing gear piece is installed, need to use special axle elastic collar, cannot use existing mounting tools, manual installation more also can make installation personnel injured.Therefore, be necessary to be improved.
Utility model content:
Goal of the invention of the present utility model is to overcome above-mentioned the deficiencies in the prior art, provides a kind of simple in structure, easily the device of elastic collar for fast speed installation shaft.
For achieving the above object, the utility model has adopted following technical scheme:
A kind of axle that internal speed-changing gear piece is installed elastic collar device, comprise internal speed-changing and elastic collar, also comprise that a hollow-cone body and is by one section of two sections of cylinder that hollow structure forms that are another section of deep end and are shallow end, described hollow-cone body is placed on the axle of described internal speed-changing, described elastic collar is coated on described hollow-cone body, first described cylindrical shallow end is inserted in to described hollow-cone body, make described elastic collar at described hollow-cone body in the parallel state that partly snaps in, again described cylindrical deep end is inserted in to described hollow-cone body, make described elastic collar in described hollow-cone body snaps in described internal speed-changing gear piece draw-in groove.
Described cylindrical deep end length is greater than the height of described hollow-cone body.
The utility model has the following advantages with respect to prior art tool:
The utility model is simple in structure, easily fast speed installation shaft elastic collar.
Brief description of the drawings:
Fig. 1 is the cutaway view that in the utility model, first step shallow end is pressed into.
Fig. 2 is the cutaway view that in the utility model, second step deep end is pressed into.
Detailed description of the invention:
Referring to Fig. 1 and Fig. 2, a kind of axle that internal speed-changing gear piece the is installed elastic collar device providing according to the utility model, comprise internal speed-changing 1 and elastic collar 2, also comprise a hollow-cone body 3 and a cylinder 4 being formed by one section of two sections of hollow structure that are another section of deep end is shallow end, hollow-cone body 3 is placed on the axle of internal speed-changing 1, elastic collar 2 is coated on hollow-cone body 3, when installation, first the shallow end of cylinder 4 is inserted in to hollow-cone body 3, make elastic collar 2 on hollow-cone body 3 in the parallel state that partly snaps in, again the deep end of cylinder 4 is inserted in to hollow-cone body 3, make elastic collar 2 in hollow-cone body 3 snaps in internal speed-changing 1 gear piece draw-in groove.The deep end length of cylinder 4 is greater than the height of hollow-cone body 3, is convenient to like this make elastic collar 2 in hollow-cone body 3 snaps in internal speed-changing 1 gear piece draw-in groove.
Above-described embodiment is only for illustration of the utility model; and be not limitation of the utility model; the those of ordinary skill in relevant technologies field; in the situation that not departing from spirit and scope of the present utility model; can also make a variety of changes and modification; therefore all technical schemes that are equal to also belong to category of the present utility model, and scope of patent protection of the present utility model should be limited by each claim.
