Description
Technical field
It the utility model is related to a kind of sealing fastening connection piece.
Background technology
Axis is fixed on crank by the crank of bicycle with axis using conventional nut or screw at present, then in spiral shell
Female or bolt outside sets plastic cover sheet, covers the junction of nut and screw, but the structure of this plastic cover sheet now
Sealing is poor, and plastic cover sheet easily comes off, if after plastic cover sheet comes off, the nut or bolt of connection will directly expose
Outside, will get rusty loosening for a long time, but because nut or bolt get rusty and can cause to be difficult to maintenance replacing.
Utility model content
Technical problem to be solved in the utility model, which is to provide one kind, can remove existing plastic cover sheet from, and connect tight
Close non-damageable sealing fastening connection piece.
Technical scheme is used by the utility model：One kind sealing fastening connection piece, it includes end cap, is arranged on end cap
The connecting shaft of lower surface and the arc crown for being arranged on end cap upper surface.
External screw thread is provided with the lateral wall of connecting shaft described in the utility model.
The lower end of connecting shaft described in the utility model is provided with connecting hole, and interior spiral shell is provided with the connecting hole inwall side
Line.
The lateral wall radial section of end cap described in the utility model is in octagon or dodecagon.
Good effect of the present utility model is：The utility model has an arc crown, can cancel plastic cover sheet during use
Structure, various patterns and color can be increased on arc crown, outward appearance is more attractive in appearance, and good airproof performance after installation, connector is not
Easily get rusty, be hardly damaged, and change and more facilitate；Connecting pole using external screw thread and internal thread two kinds of forms, can with not
Isostructural middle axis connection, use range are wide.
Brief description of the drawings
Fig. 1 is the utility model structure diagram；
Fig. 2 is the structural representation of the utility model embodiment 1；
Fig. 3 is the structural representation of the utility model embodiment 2；
Fig. 4 is the cross section structure diagram of the utility model embodiment 2.
Embodiment
Embodiment 1：As shown in accompanying drawing 1,2, the utility model includes end cap 1, is arranged on the connecting shaft 2 of the lower surface of end cap 1
And the arc crown 3 of the upper surface of end cap 1 is arranged on, it is provided with and is used for and bicycle middle shaft on the lateral wall of the connecting shaft 2
The external screw thread of connection, the lateral wall radial section of the end cap 1 is hexagonal or octagon or dodecagon or other art
Shape.
Embodiment 2：As shown in accompanying drawing 1,3,4, only the structure of connecting shaft 2 is modified on the basis of embodiment 1, institute
The lower end for stating connecting shaft 2 is provided with connecting hole 4, and screw thread is provided with the inwall side of connecting hole 4.
The utility model directly increases curved crown 3 on end cap, and end cap contacts with the crank of bicycle during use,
The plastic cover sheet structure of script can be saved, installation is more convenient with dismounting, and connection is also more firm, while the utility model
Entirety can use same material, be hardly damaged, use cost is relatively low.Existing plastic cover sheet is when mounted, it is necessary in crank
Corresponding installation portion tapping to fixed plastics cover plate, it is right and the step of use the utility model then can be with completely left out tapping
Crank manufacture requires low, has saved the manufacturing process of crank, makes crank manufacture simpler.The lower surface of end cap and crank simultaneously
Contact, contact area is big, and connection is even closer, firm, reduces spoilage.
