Description

Cyclic dart

Technical field

The utility model relates to a kind of Cyclic dart with light emitting diode in order to play and to heighten the enjoyment at night.

Background technology

Cyclic dart is as a kind of ancient and magical flight appliances, is deeply subject to the liking of people of all age group.Be V-type Cyclic dart at first, then occur that trilobal, quatrefoil etc. are multi-leaf-shaped.Cyclic dart is very popular in American-European countries, Australia, China, people using it as a kind of fashion, a kind of motion and a kind of game.For the Cyclic dart fan of daytime in work, only can play the time at night, children also have the such idea of Cyclic dart of playing evening.

But existing Cyclic dart is due to cannot be luminous, once after being dished out, be difficult to recover, therefore need to design a kind of can be at night or the darker visible Cyclic dart of occasion of light.

Utility model content

Thereby the purpose of this utility model be to provide a kind of can be luminous at night or the darker visible Cyclic dart of occasion of light.

The utility model provides a kind of Cyclic dart, has such feature, comprising: Cyclic dart body; At least one light emitting diode, is arranged on Cyclic dart body; And gauge tap loop, be arranged at the center of Cyclic dart body, contain: power supply, is used to light emitting diode power supply; And switch, be connected between power supply and light emitting diode, for being communicated with or disconnecting gauge tap loop, wherein, switch is centrifugal spring loaded switch, the rotation of being dished out of Cyclic dart body, in the time that the centrifugal force of Cyclic dart body is greater than certain numerical value, centrifugal spring loaded switch is elongated, gauge tap loop is switched on, in the time that the centrifugal force of Cyclic dart body is less than certain numerical value, centrifugal spring loaded switch shortens and recovers normal length, and gauge tap loop is disconnected.

In the Cyclic dart providing at the utility model, also there is such feature, comprising: wherein, light emitting diode quantity is one, with switch overlaid, be positioned on Cyclic dart body center.

In the Cyclic dart providing at the utility model, also there is such feature, comprising: wherein, light emitting diode quantity is two, be positioned at Cyclic dart body with respect on the symmetrical position of switch.

Utility model effect

According to the related Cyclic dart of the utility model, by light emitting diode and gauge tap loop are set on Cyclic dart body, can control opening and closing of light emitting diode by switch, finally make the Cyclic dart can be luminous, thus can for people at night or the darker occasion of light play.

Detailed description of the invention

Referring to drawings and Examples, the related Cyclic dart of the utility model is explained in detail.

< embodiment mono->

Fig. 1 is the structural representation of facing of the Cyclic dart of the utility model in embodiment mono-.

As shown in Figure 1, Cyclic dart 100 has Cyclic dart body 12 and a 3V light emitting diode 11.Cyclic dart body 12 is " V font ".3V light emitting diode 11 is positioned over Cyclic dart body 12 front center positions, is embedded in and revolves on boomerang body 12.

Fig. 2 is the structure schematic diagram of the Cyclic dart of the utility model in embodiment mono-.

As shown in Figure 2, Cyclic dart 100 also has the push-button switch loop 13 that is placed on Cyclic dart body 12 centers, the back side.

Fig. 3 is the circuit diagram in the push-button switch loop 13 of the utility model in embodiment mono-.

As shown in Figure 3, push-button switch loop 13 has 3V power supply 31, push-button switch 32 and 3V light emitting diode 11.

3V power supply 31, for powering to light emitting diode 11.

Push-button switch 32 is connected between 3V power supply 31 and 3V light emitting diode 11, and in the time that push-button switch 32 is pressed, push-button switch loop 13 is connected, and lights 3V light emitting diode 11; When push-button switch 32 is opened, push-button switch loop 13 is disconnected, and extinguishes 3V light emitting diode 11.

The effect of embodiment mono-and effect

The Cyclic dart relating to according to embodiment mono-, can open or close light emitting diode easily by pressing push-button switch, and the formula switch of pressing the button is lighted light emitting diode can make luminous at night of Cyclic dart in the air, increases entertaining.In the time that end Cyclic dart is played, again press the button formula switch, light emitting diode is not luminous.

< embodiment bis->

It is below the explanation to embodiment bis-.

In embodiment bis-, for embodiment mono-in identical structure, give identical symbol, and omit identical explanation.

In embodiment bis-, Cyclic dart is identical with the Cyclic dart 100 in embodiment Fig. 1 mono-from facing the structure of observation, omits same explanation at this

Fig. 4 is the back of the body TV structure schematic diagram of the Cyclic dart of the utility model in embodiment bis-.

As shown in Figure 4, Cyclic dart 200 has the centrifugal spring loaded switch loop 14 that is placed on Cyclic dart body 12 centers, the back side.

Fig. 5 is the circuit diagram in the centrifugal spring loaded switch loop 14 of the utility model in embodiment bis-.

As shown in Figure 5, centrifugal spring loaded switch loop 14 has 3V power supply 31, centrifugal spring loaded switch 41 and 3V light emitting diode 11.

Centrifugal spring loaded switch 41 adopts the hairspring silk of 0.3 millimeter of diameter, external diameter 3-6 millimeter.

Cyclic dart body 12 rotation of being dished out, in the time that the centrifugal force of Cyclic dart body 12 is greater than 5N, centrifugal spring loaded switch 41 is elongated, and connects centrifugal spring loaded switch loop 14, lights 3V light emitting diode 11; In the time that the centrifugal force of Cyclic dart body 12 is less than 5N, centrifugal spring loaded switch 41 shortens and recovers normal length, disconnects centrifugal spring loaded switch loop 14, extinguishes 3V light emitting diode 11.

The effect of embodiment bis-and effect

The Cyclic dart relating to according to embodiment bis-, the Cyclic dart of only need dishing out makes its rotation, can open light emitting diode by the elongation of centrifugal spring, after Cyclic dart stops the rotation, the centrifugal spring being elongated shortens immediately and becomes former length again, close light emitting diode, can make Cyclic dart luminous in the time playing night, not only convenient but also be full of enjoyment.

Above-described embodiment one and embodiment bis-are preferred case of the present utility model, are not used for limiting protection domain of the present utility model.
