Description
Technical field
The present invention relates to a kind of bicycle aluminium-alloy rim structures, belong to alloy product technical field.
Background technique
Bicycle rim made of aluminum alloy has the advantages that light-weight, hardness is high and handsome in appearance, in aluminium alloy rim
It is that aluminium alloy bar stock extrusion forming by edge rolling processing program, is obtained into the shape of wheel rim, wheel after molding in manufacturing process
Load is being open, and traditional handicraft is that the both ends that will be open are welded, but the seam welded is easy cracking, and welding not can guarantee
The out of roundness of wheel rim.It exists in the prior art and realizes opening in the connecting hole by prefabricated connecting rod insertion opening both ends
Engagement, which has the advantages that prevent gaping of joints and connection precision is high, but there are connecting rods to connect by force with connecting hole
Spend it is low and the problem of loosen, there is also two lateral connector bars loosen degree it is different and the problem of cause wheel rim to deform；Moreover,
In wheel rim load-bearing, when supporting point goes to opening, the simple intensity by connecting rod also be easy to cause combination as support
Place misplaces.
Summary of the invention
The purpose of the present invention is to provide a kind of bicycle aluminium-alloy rim structures, the specific scheme is that
The opening of a kind of bicycle aluminium-alloy rim structure, the rim body including opening, rim body is equipped with connection
Head, two connectors are connected by master link, and the two sidewalls of the connector are equipped with the connecting hole for installing master link；Institute
Stating master link includes that the path section positioned at both ends is equipped with through-hole with major diameter section, the major diameter section is located in the middle；The connection
Hole, which is equipped with, is embedded with the master with the matched internal diameter holes of master link and external large diameter hole, the connecting hole for connecting both sides of head
Connecting rod；The end face of the connector is equipped with the end face groove through two connecting holes, and the both ends of end face groove are through to connector
Lateral wall；Tranverse connecting rod is equipped in end face groove, tranverse connecting rod runs through the through-hole of master link, and the both ends of tranverse connecting rod are through to connector
Lateral wall, and the both ends of tranverse connecting rod are fixed by nuts.
Further, the both ends of the tranverse connecting rod are fixed with U-shaped buckle by nut, and the lateral wall of connector is equipped with snapping
The both ends of slot, the U-shaped buckle are respectively embedded into the snap groove of two connectors.
Further, the end face groove is V-groove, and V-groove runs through connector side surface side and bottom simultaneously；The horizontal company
Bar is the V-type bar matched with end face groove.
Further, the major diameter section of the master link is rectangular, and path section is circle.
Compared with traditional aluminium alloy rim, master link is arranged bicycle aluminium-alloy wheel rim in this programme along interface
It is linked into an integrated entity at major diameter section, and between two master links by tranverse connecting rod, the integral strength of interface can be improved, and
Tranverse connecting rod is embedded in the end face groove of two connectors, can be played the role of enhancing bonding strength, be prevented connector from misplacing.
In addition, the side wall of two connectors also passes through U-shaped buckle and connects in improvement project, and U-shaped buckle equally with master link and cross
Connecting rod is combined into one, and can preferably improve integrated connection intensity.
