Description

Informationized teaching pen

Technical Field

The utility model relates to a stationery technical field specifically indicates an information-based teaching pen.

Background

At present, teaching pens are mainly made of chalk and liquid chalk. The chalk is generally calcium carbonate, easy to hurt the skin of fingers, the fingers are very unhygienic to contact the chalk directly, and the chalk is very difficult to use again after being shortened, and only can be discarded, so that the waste is caused, the environment is polluted, and the existing chalk sleeve is manufactured for slowing down the phenomenon that the chalk is produced by hand contact and is infected with chalk powder when in use; the liquid chalk is nontoxic, harmless, noiseless, free of dust and environment-friendly, but a pen cap is also needed to be used as a container for containing the liquid chalk and is used in a conversion mode. However, for manufacturers or liquid chalk caps, two molds are required to be prepared for producing the chalk caps or the liquid chalk caps, and for users, two different chalk caps corresponding to chalk and liquid chalk are required to be prepared, so that resources are wasted when the chalk caps or the liquid chalk caps are prepared and purchased in double parts.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is to solve above-mentioned problem, provide an information-based teaching pen of consequently providing a pen socket dual-purpose, resources are saved and cost.

In order to solve the technical problem, the utility model provides a technical scheme does: an informationized teaching pen comprises a pen container, wherein inner threads are arranged on the inner wall of the pen container, a plunger is inserted on the pen container, the outer side surface of the upper end of the plunger is circumferentially provided with a waistcoat, the upper surface of the plunger is provided with a handle, one side of the lower surface of the plunger is provided with a limiting plate, a rotating plate is arranged at the other side below the plunger, the limiting plate and the rotating plate are both semicircular, the radius of the limiting plate is larger than that of the rotating plate, a transverse plate is arranged on the rotating plate, an external thread matched with the internal thread is arranged on the outer side surface of the rotating plate, the limiting plate extends to the lower end in the pen container, a limiting ring is arranged on the outer side surface of the pen container and close to the lower end, the pen container is characterized in that a pen point is arranged on the outer side surface of the pen container and lower than the limiting ring in a threaded connection mode, the lower end of the pen point is conical, a mounting hole is formed in the lower surface of the pen point, and a sponge soft pen point is inserted into the mounting hole.

Due to the adoption of the technical scheme, the beneficial effects of the utility model reside in that: when using the liquid chalk, only need pull out the plunger, then to the inside liquid chalk that injects of pen container, the liquid chalk flows in to the nib end, is absorbed by the soft nib of sponge again, alright write, when to the needs chalk, twist off the nib and need not, then pull out the plunger, detain the rotor plate in the chalk upper end, then put into the space between the plunger and the limiting plate together with the chalk in, then in stuffing the pen container back with the plunger, the chalk lower extreme just comes out from the pen container other end in, can write, the utility model discloses simple structure, a dual-purpose, producer or consumer only need purchase/produce this kind of pen socket, alright be used for adorning chalk or liquid chalk, hold many, save the resource.

Furthermore, the pen cap is connected with the pen cap, so that the sponge soft pen point is protected, and the ink loss and the pollution of the pen are prevented.

Furthermore, a sealing gasket is arranged below the waistcoat, so that the connection sealing performance is improved.

Furthermore, the rotating plate is made of elastic materials, the limiting plate rotates to drive the rotating plate to rotate and descend, so that the inner side face of the rotating plate is in close contact with the chalk, the chalk cannot fall into the pen container, and the rotating plate is made of elastic materials for increasing the close contact with the chalk.
