CN2905462Y - Rotating projection pen - Google Patents

Abstract

The utility model is related to a rotary projection pen. Its pen holder consists of an upper tube, a lower tube, a nib, a grip and a connector that connects the upper tube and the lower tube, and contains a refill, an extendable spring that encloses the refill, and a lift part. The top of the lift part is connected with a contact part, and the top of the contact part is equipped with a conducting spring which is electrically connected with the battery and the luminescent device. Likewise, the luminescent device is also electrically connected with the battery. Before the luminescent device are the lens, the film and another lens in order, and the top of the upper tube is provided with a transparent pen cover. The more reasonable arrangement of the various components in the pen creates a better effect of projection, and the adoption of the rotary structure avoids the mishandling by the user due to carelessness.

Description

Rotary projection pen

Technical field

The utility model relates to a kind of stationery, and especially a kind of rotation by penholder realizes the pen of projecting function.

Background technology

Existing pen with Communications Functions normally directly is printed on publicity literature or pattern on the penholder, but this method is too traditional, can not come into the picture.Therefore, a kind of novel pen that figure film and light projection's device are set has appearred in the market, to strengthen the effect of publicity of pen in pen.Yet above-mentioned projection pen generally adopts key switch control, and the user need pin switch for a long time when realizing projecting function, and this kind structure makes user's false touch gauge tap under being not intended to, waste electric energy easily.

Summary of the invention

The purpose of this utility model is at present the effect of publicity not remarkable, and perhaps the undesirable deficiency that waits of control mode provides a kind of novel projection pen that adopts rotation mode to realize projecting function.

Technical solution of the present utility model is: a kind of rotary projection pen, penholder is by last pipe, following pipe, mouth, handle and up and down the meson between the pipe be connected to form, pen core is installed in the penholder, be enclosed within the coil tension spring on the pen core and the parts that rise and fall, rise and fall parts the top with touch part and be connected, touch the top of part power spring is installed, power spring is electrically connected with battery and light-emitting device by conducting ring and conducting strip, light-emitting device is electrically connected equally with battery, the place ahead of light-emitting device is provided with lens successively, figure film and another lens, the top of last pipe are provided with a transparent cap for brush.

The beneficial effects of the utility model are: because the setting of each parts is more reasonable in the pen, so the effect of projection is more clear; In addition, owing to adopt rotary structure, so the maloperation that produces because of carelessness owing to the user can not occur.

The specific embodiment

Specific embodiment of the utility model as shown in Figures 1 and 2, a kind of rotary projection pen, penholder is by last pipe 2, under manage 17, mouth 15, handle 16 and up and down the meson between the pipe 18 be connected to form, pen core 14 is installed in the penholder, be enclosed within the coil tension spring 8 on the pen core 14 and the parts 9 that rise and fall, rise and fall parts 9 the top with touch part 10 and be connected, touch the top of part 10 power spring 11 is installed, power spring 11 is electrically connected with battery 7 and light-emitting device 6 by conducting ring 12 and conducting strip 13, light-emitting device 6 is electrically connected equally with battery 7, the place ahead of light-emitting device 6 is provided with lens 5 successively, figure film 4 and another lens 3, on manage 2 top and be provided with a transparent cap for brush 1.

During use, pipe 2 in the rotation, under the effect of rise and fall parts 9 and coil tension spring 8, pen core 14 stretches out a mouth 15, and part 10 and the power spring 11 that touch at parts 9 tops of rising and falling connected with a utmost point of battery 7 and light-emitting device 6 by conducting ring 12 and conducting strip 13, at this moment, light-emitting device 6 is luminous, and rays pass through lens 5 shines on the figure film 4, penetrates from the light transmission part of figure film 4 subsequently, after passing through another lens 3 and the transparent cap for brush 1 again, the projection pattern on the film 4 of publishing picture.When managing 2 in the reverse rotation, the touch part 10 and power spring 11 meetings and battery 7 that are installed in parts 9 tops of rising and falling disconnect, and pen core 14 rebounds in the penholder.

Claims (1)

1. rotary projection pen, penholder is by last pipe, following pipe, mouth, handle and up and down the meson between the pipe be connected to form, pen core is installed in the penholder, be enclosed within the coil tension spring on the pen core and the parts that rise and fall, it is characterized in that: the top of the parts that rise and fall with touch part and be connected, touch the top of part power spring is installed, power spring is electrically connected with battery and light-emitting device by conducting ring and conducting strip, light-emitting device is electrically connected equally with battery, the place ahead of light-emitting device is provided with lens successively, figure film and another lens, the top of last pipe are provided with a transparent cap for brush.
