Abstract

An adjusting washer is arranged on a headset of a bicycle and comprises an annular shim and an elastic buckle. An elastic groove is arranged on the annular shim along the radial direction, and a groove is arranged on the outer periphery of the annular shim in circle mode. The elastic buckle is sleeved in the groove and provided with a notch. Accordingly, when the headset of the bicycle is arranged on a front fork pipe of the bicycle in sleeve mode, and the front fork pipe provides radial applied force for the annular shim, the elastic buckle provides counter force, and the annular shim can not crack caused by centralized force when the annual shim is stressed radically.

Description

The adjustment packing ring

Technical field

The adjustment packing ring of a kind of bicycle car of the utility model bowl group refers in particular to a kind of adjustment packing ring that prevents to produce because of radial stress fracture that reaches.

Background technique

Become a kind of trend at present by bike; Can not only go in for physical training and also can have environmental protection concurrently; Become a kind of motion that is popular among the people, influence wherein that bicycle is controlled, the key of balance is bicycle profile tube, the assembling of front fork tube and headstock bowl group structure, so the part of headstock bowl group also has very important influence for quality, the Security of bicycle; Wherein, the pad of headstock bowl group need possess effect locking, that increase, protect internal structure.

Bicycle is commonly used ring washer and the ostiolate C-washer that the packing ring branch is one of the forming at present; Right bicycle front fork pipe caliber is all than the circle footpath greater than the packing ring inner peripheral surface; So when integrally formed ring washer side face receives the radial pressure of front fork tube; Be prone to make ring washer generation internal stress and cause fracture, let packing ring lose effect locking, the protection internal structure.

Yet; Though C-washer can bear big radial force with respect to ring washer; But because of force bearing point in the opening two ends and the opening opposite end produce 3 stress and concentrate, still can make C-washer produce fracture, make packing ring lose effect locking, the protection internal structure; The cost that damages when making the manufacturer not only increase the packing ring assembling, the man-hour that increases when also causing assembler's assembly product.

Summary of the invention

In view of addressing the above problem, the purpose of the utility model is, a kind of adjustment packing ring is provided, and it can reach and prevent that packing ring receives internal stress and produces fracture.

A kind of adjustment packing ring of the utility model is installed in the headstock bowl group of bicycle, and it consists predominantly of:

One annular gasket has the elastic groove that radially is provided with, and this annular gasket outer periphery place is equipped with a groove; And

One elasticity button is sheathed in above-mentioned this groove, has a breach on it;

By this, this elasticity button provides a reaction force, the not concentrated fracture of stress when making this annular gasket radial force.

Wherein, this annular gasket is arranged with an elastic ring, is set around elasticity button outer circumferential face.

Wherein, this annular gasket one side extends axially an extension along inner circumference edge, and this extension outer circumferential face is provided with the conical surface by the end flaring.

The utility model beneficial effect: the front fork tube that is placed in a bicycle when this bicycle headstock bowl assembling; This front fork tube provides and radially forces in this annular gasket; This moment, this elasticity button provided a reaction force, the not concentrated fracture of stress when making this annular gasket radial force.

For ease of explanation this case represented central idea in above-mentioned novel content one hurdle, express with specific embodiment now.Various different objects are in being suitable for giving an example the ratio of explanation among the embodiment, but not draw in the ratio of actual components, close chat earlier bright.

Embodiment

Shown in Fig. 2～Fig. 4 drawing, a kind of adjustment packing ring 10 of the utility model is installed in the headstock bowl group of bicycle, and it consists predominantly of:

One annular gasket 11; These annular gasket 11 1 sides extend axially an extension along inner circumference edge; These extension 111 outer circumferential faces are provided with the conical surface 112 by the end flaring, and this annular gasket 11 has the elastic groove 12 that radially is provided with, and these annular gasket 11 outer periphery places are equipped with a groove 13;

One elasticity button 14 is sheathed in above-mentioned this groove 13, has a breach 15 on it, and its breach 15 places and this elastic groove 12 misplace relatively;

One elastic ring 16 is sheathed on the outer circumferential face of an elasticity button 14, and is placed in the groove 13 of annular gasket.

After clear above-mentioned this case detailed structure, below the operating principle to this case specifies one by one:

Shown in Fig. 1～Fig. 5 drawing; This adjustment packing ring 10 is installed in a bicycle headstock bowl group 20, wherein should adjust the lining inner circumference edge of the conical surface 112 relative engagement in headstock bowl group 20 of annular gasket 11 its extensions 111 of packing ring 10, and this headstock bowl group 20 is sheathed on a front fork tube 30; Groove 13 places of this annular gasket 11 are provided with elasticity and buckle 14; Make this annular gasket 11 when strutting, elasticity button 14 provides an opposition, with the strength of disperseing annular gasket 11 to be born; Make annular gasket 11 slow down radial force suffered when strutting; And these elasticity button 14 outer circumferential face winding elastic rings 16 reach close-fitting effect during with 21 assemblings of the enclosing cover of this headstock bowl group 20, and the elastic buffer of this elasticity button 14 when strutting is provided.

Shown in Fig. 5～Fig. 8 drawing, because bicycle front fork pipe 30 calibers make these annular gasket 11 inner peripheral surfaces strutted outward by radial pressure all greater than annular gasket 11 inner peripheral surfaces; Make elastic groove 12 two ends and elastic groove 12 opposed ends of this annular gasket 11; Because of receiving its radial pressure to produce internal stress, this moment, the elasticity button provided an opposition, and its opposition can be slowed down the radial force of annular gasket 11 supports when big; Thereby reduce elastic groove 12 two ends and elastic groove 12 opposed ends of this annular gasket 11; 3 internal stresss that produced by its radial pressure make opposed end reduce the fracture chance, reach to prevent packing ring fracture and locking purpose.

Though this case is to do explanation with a most preferred embodiment, is skillful in this art and can makes various multi-form changes not breaking away under this case spirit and the category.The above embodiment that lifts is only in order to explanation this case, and is non-in order to limit the scope of this case.Such as do not disobey various modifications or the variation that this case spirit is engaged in, all belong to this case claim.
