the pointer comprises a rotating arm, a linkage arm and a connecting rod, the rotating arm and the linkage arm are respectively positioned on two sides of the bottom plate, the connecting rod vertically penetrates through the bottom plate, and two ends of the connecting rod are respectively fixedly connected with the rotating arm and the linkage arm;
the finger shifting transmission comprises a wire wheel, wherein a convex column is arranged on one side of the wire wheel, which is opposite to the bottom plate, and the convex column is connected with a rotating arm of the pointer.
In a preferred embodiment of the present invention, a side of the rotating arm facing the protruding pillar has an arc groove, and the protruding pillar is inserted into the arc groove to drive the rotating arm to rotate synchronously.
In a preferred embodiment of the present invention, the portable electronic device further comprises a bottom plate cover, a cavity is formed between the bottom plate cover and the bottom plate, and the linkage arm of the pointer is embedded in the cavity.
The utility model has the advantages that: the utility model relates to a two handles of bicycle indicate group derailleur display device, simple structure, reasonable in design, it is through setting up the projection on line wheel to make projection and pointer fixed connection, make advancing the shelves and moving back the in-process, because the rotation of line wheel drives the pointer and rotates, make the location of pointer about the gear reliable, directly perceived, the practicality is stronger.
Drawings
FIG. 1 is a schematic perspective view of a preferred embodiment of a dual-handle derailleur display device for a bicycle of the present invention;
FIG. 2 is a schematic diagram of the structure of the pointer;
FIG. 3 is a schematic bottom view of the rotating arm of the pointer;
the parts in the drawings are numbered as follows: 1. the pointer comprises a pointer body, a bottom plate 2, a bottom plate cover 3, a wire wheel 4, a convex column 5, a rotating arm 11, a linkage arm 12 and a connecting rod 13.
Detailed Description
The following detailed description of the preferred embodiments of the present invention will be provided in conjunction with the accompanying drawings, so as to enable those skilled in the art to more easily understand the advantages and features of the present invention, and thereby define the scope of the invention more clearly and clearly.
Referring to fig. 1-3, an embodiment of the present invention includes:
example 1
The utility model discloses a two handles of bicycle indicate group derailleur display device, include: pointer 1, bottom plate 2, bottom plate lid 3 and finger dial derailleur assembly.
The pointer 1 and the finger shifting transmission assembly are respectively arranged on two sides of the bottom plate 2.
The pointer 1 comprises a rotating arm 11, a linkage arm 12 and a connecting rod 13, the rotating arm 11 and the linkage arm 12 are respectively located on two sides of the bottom plate 2, the connecting rod 3 vertically penetrates through the bottom plate 2, and two ends of the connecting rod are respectively fixedly connected with the rotating arm 11 and the linkage arm 12.
A cavity is formed between the bottom plate cover 3 and the bottom plate 2, and the linkage arm 12 of the pointer 1 is arranged in the cavity.
The dial transmission assembly comprises a wire wheel 4, one side of the wire wheel 4, which is opposite to the bottom plate 2, is provided with a convex column 5, and the convex column 5 is connected with a rotating arm 11 of the pointer 1. Specifically, the swinging boom 11 is towards one side of projection 5 has an arc groove 14, projection 5 insert the cooperation to in the arc groove 14, drive swinging boom 11 synchronous rotation realizes the rotation of pointer.
The utility model discloses a theory of operation does:
when the gear is shifted, when a gear shifting handle in the finger shifting transmission assembly is pulled, the gear shifting handle drives the wire wheel to rotate, so that a convex column on the wire wheel rotates, the convex column pushes the rotating arm 11 to rotate through the arc groove 14, and the whole pointer is driven to rotate;
when the gear is withdrawn and the gear withdrawing handle in the finger shifting transmission assembly is pulled, the gear feeding handle drives the wire wheel to rotate, so that the convex column on the wire wheel rotates, the convex column pushes the rotating arm 11 to rotate through the arc groove 14, and the whole pointer is driven to rotate.
The utility model relates to a two handles of bicycle indicate group derailleur display device, simple structure, reasonable in design, it is through setting up the projection on line wheel to make projection and pointer fixed connection, make advancing the shelves and moving back the in-process, because the rotation of line wheel drives the pointer and rotates, make the location of pointer about the gear reliable, directly perceived, the practicality is stronger.
