Description

Technical Field

[0001] The utility model belongs to the technical field of bicycle parts, in particular to a transmission hanger for a sports bicycle. Background Art

[0002] With the popularity and rising prices of sports bicycles, the derailleurs and bodies of bicycles are made of relatively sophisticated structures and expensive materials. The bicycle derailleur hangers are made of relatively brittle aluminum alloy materials. They serve as the structure that breaks and deforms first when a rider falls or the bicycle is subjected to external forces. This can protect the frame or derailleur and reduce the risk of damage. However, most hanger designs are too complex for universality, are heavy, and are difficult to be compatible with rear derailleurs of other brands.

[0003] Therefore, how to provide a sports bicycle transmission hanger is a problem that those skilled in the art urgently need to solve. Utility Model Content

[0004] The purpose of the utility model is to provide a transmission hanger for a sports bicycle, aiming to solve the problems mentioned in the background technology.

[0005] The utility model is implemented as follows: a sports bicycle transmission hanging ear comprises:

[0006] Frame mounting plate;

[0007] A positioning screw barrel, which is fixedly mounted on the upper end of the frame mounting plate and has an internal thread on its inner side;

[0008] A connecting piece is movably inserted into the interior of the positioning screw barrel, and a connecting piece corresponding to the internal thread is provided on the surface.

[0009] Preferably, the frame mounting plate is arranged at one end of the wheel center axis, and the thread directions of the positioning screw barrel and the connecting member are arranged opposite to the wheel mounting direction.

[0010] Preferably, a connecting nut is fixedly mounted on the lower end of the frame mounting plate for mounting the transmission.

[0011] Preferably, a shock-absorbing gasket is provided between the positioning screw barrel and the connecting piece, a through hole is provided in the middle of the shock-absorbing gasket, and the left end of the connecting piece passes through the through hole and is connected to the positioning screw barrel.

[0012] Preferably, a groove is provided on the inner side of the right end of the shock-absorbing gasket, and the diameter of the right end of the connecting piece is the same as the inner diameter of the groove.

[0013] Preferably, a hexagonal groove is provided at the right end of the connecting piece for installation and removal of the connecting piece.

[0014] Compared with the prior art, the beneficial effects of the present invention are: when in use, the frame mounting plate is fixed to the frame by plugging the positioning screw barrel at the top end of the frame mounting plate into the frame and arranging a connecting piece in the positioning screw barrel, and because the positioning screw barrel and the connecting piece are both arranged in a circular shape, it can be applicable to a variety of frames with circular connection structures, and is more streamlined and lighter than the existing frame mounting plate structure.

[0015] At the same time, by setting the external spiral connection direction of the internal thread on the positioning screw barrel and the connecting piece to be opposite to the spiral direction of the wheel on the central axis during installation, when the wheel is removed, the frame mounting plate will not loosen as the wheel is removed, thereby causing the trouble of requiring secondary installation.
