Abstract

The utility model discloses a flashing wheel, which comprises a transparent wheel body. Lamp bodies are arranged in the wheel body. The wheel body is provided with a shaft core hole. A shaft core is installed in the shaft core hole. The shaft core is a magnetic core which is made of magnetic plastics. A coil which is matched with the shaft core to generate electricity by friction is wound on the inner wall of the shaft core hole at a position corresponding to the magnetic core. The coil is electrically connected with the lamp bodies. By adopting the structure, the flashing wheel not only has a simple structure and is easy to manufacture, but also has the advantages that since the shaft core does not use a great quantity of complex workpieces in the traditional structure, the connection between the shaft core and the wheel body is closer and firmer, a gap does not exist, off-centering and swinging are not caused when the flashing wheel is used, the service life is long, the cost of the magnetic core made of the magnetic plastics is very low and the flashing wheel can be particularly and industrially popularized and applied.

Description

Flashing wheel

Technical field

The utility model relates to a kind of wheel, relates in particular to a kind of flashing wheel.

Background technology

Flashing wheel of the prior art is widely used in the various wheel assemblies such as Rocking cycle; The workpiece that yet present flashing wheel structure is all very complicated, all have number of complex; Manufacture difficulty is big, and productive costs is high, and is easy to generate certain clearance between axle core and the wheel body; Can be eccentric during use, generation is rocked.

The utility model content

In view of this, the utility model technical matters to be solved is: provide a kind of simple in structure, make easily the flashing wheel that productive costs is low.

In order to achieve the above object, the utility model adopts following technical scheme to realize:

A kind of flashing wheel wherein, comprises the wheel body of printing opacity; Be provided with lamp body in the said wheel body; Said wheel body has a core hole, and attaching has a core in the said axle core hole, the magnetic core of said axle core for being made up of magnetic plastics; Said axle core hole is arranged with the coil of adaptive and said axle core frictional electricity on the position of the corresponding said magnetic core of inwall, said coil is electrically connected on said lamp body.

Can know that by technique scheme the beneficial effect of the utility model is:

Compare prior art, the utility model is through adopting said structure, and is not only simple in structure; Make easily, and owing to an axle core does not adopt number of complex workpiece in the conventional confguration, the connection between axle core and the wheel body is more closely with firm; Can not produce the gap, can be not eccentric during use with rock long service life; The magnetic core cost that is made up of magnetic plastics is very low, is fit to very much the promotion and application on industry and the industry.

The specific embodiment

In order to make those skilled in the art can further understand the characteristic and the technology contents of the utility model, see also following detailed description and accompanying drawing about the utility model.

See also Fig. 1 to shown in Figure 2, the utility model provides a kind of flashing wheel, wherein; Comprise the wheel body 1 of printing opacity, be provided with lamp body 2 in the said wheel body, said wheel body has a core hole 3; Attaching has a core 4 in the said axle core hole; The magnetic core of said axle core for constituting by magnetic plastics, said axle core hole is arranged with the coil 5 of adaptive and said axle core frictional electricity on the position of the corresponding said magnetic core of inwall, and said coil is electrically connected on said lamp body.

But the preferable possible embodiments that the above is merely the utility model is not the claim in order to limitation the utility model, so the equivalent structure that all utilization the utility model specification sheetss and accompanying drawing content are done changes, all in like manner is included in the scope of the utility model.

Claims

1. a flashing wheel is characterized in that, comprises the wheel body of printing opacity; Be provided with lamp body in the said wheel body; Said wheel body has a core hole, and attaching has a core in the said axle core hole, the magnetic core of said axle core for being made up of magnetic plastics; Said axle core hole is arranged with the coil of adaptive and said axle core frictional electricity on the position of the corresponding said magnetic core of inwall, said coil is electrically connected on said lamp body.
