Abstract

The invention relates to a posture correcting pen, which comprises a pen sleeve, a refill, a battery, an infrared transmitting tube, an infrared receiving tube, a circuit board, a coil, a movable bolt and a magnetic rod. The movable bolt and the magnetic rod are arranged inside the pen sleeve. The movable bolt abuts against the end of the refill. The central portion of the movable bolt is equipped with a radial groove and one end of the magnetic rod arranged vertical to the axial direction of the refill abuts against the radial groove. The coil is arranged at the other end of the magnetic rod. When infrared rays emitted by the infrared transmitting tube are received by the infrared receiving tube, the coil is conducted and the magnetic rod attracted by the coil departs from the radial groove. By utilizing the gesture correcting pen, when the two eyes of a student are lower than the normal height during writing, the magnetic rod is attracted by the coil and the movable bolt can freely move along the axial direction due to the absence of the axial abutting of the magnetic rod. Then the refill abutted by the movable bolt is retracted inside the pen sleeve and the student can not write any more. Therefore, the gesture correcting purpose during writing can be realized.

In the posture-correcting pen described in the utility model, on the described bar magnet back-moving spring is installed.

In the posture-correcting pen described in the utility model, the intersection of described groove and movable bolt is a smooth surface.

In the posture-correcting pen described in the utility model, also be provided with fairlead in the described pen cap, described bar magnet is arranged in this fairlead.

In the posture-correcting pen described in the utility model, when the student write eyes be lower than normalized distance from the time, the infrared ray that infrared emission tube sends will be blocked and be received by infrared receiver tube, at this moment, described coil conducting and produce the magnetic that differs from described bar magnet one end, according to the principle that there is a natural attraction between the sexes, described bar magnet is attracted to coil, thereby make the radial groove of this bar magnet disengaging activity bolt, this activity bolt can be axially free movable along it owing to lose radially replacing of bar magnet, just make in the pen core withdrawal pen cap that this activity bolt replaces, thereby make the student can't continue to write, reached the purpose of correcting writing posture.

Description of drawings

Fig. 1 is the structural representation of posture-correcting pen described in the utility model.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is described in further detail, can implements according to this with reference to the specification literal to make those skilled in the art.

Posture-correcting pen described in the utility model is the improvement of carrying out at Chinese utility model patent ZL200620010200.6, and the described posture-correcting pen of the utility model patent has overcome the drawback that pen core among the Chinese utility model patent ZL200620010200.6 can't secure fixation.

Particularly, as shown in Figure 1, similar with aforementioned structure of the prior art, posture-correcting pen described in the utility model comprises the pen cap 1, is arranged at pen core 2, battery 3, infrared emission tube 4, infrared receiver tube 5, circuit board 6 and coil 7 in the pen cap 1.Improvements are to increase in the pen cap 1 and are provided with movable bolt 8 and bar magnet 9, described movable bolt 8 is resisted against the end of pen core 2, offer radial groove 10 at the middle part of this activity bolt 8, described radial groove 10 is replaced by an end of the bar magnet 9 that axially is provided with perpendicular to pen core 2, for guaranteeing to replace effect, avoid unnecessary part to interfere, the intersection with radial groove 10 and movable bolt 8 in the utility model is processed as level and smooth curved surface.

In the utility model, change has taken place in the position of described coil 7, and is corresponding with the direction of aforementioned bar magnet 9, and this coil 7 is set to the other end of bar magnet 9.When the infrared ray that sends when infrared ray transmitting tube 4 was received by infrared receiver tube 5, described coil 7 conductings also produced the magnetic of the other end that differs from bar magnet 9.According to the principle that there is a natural attraction between the sexes, described bar magnet 9 is attracted to coil 7, thereby breaks away from radial groove 10.So, movable bolt 8 for want of bar magnet 9 restriction and can be free movable, again since this moment pen core 2 be contacted with paper, so described pen core 2 is pushed up go back to the pen cap 1 inside.Also promptly when student's eyes apart from paper distance be lower than normalized distance from the time, its face stops the infrared ray that infrared emission tube 4 sends, thereby makes infrared receiver tube 5 receive infrared ray, and then makes the circuit turn-on of coil 7, produce the suction of absorption bar magnet 9, make at last in the pen core 2 withdrawal pens cap 1.The student mistake occurs because of continuing to write the writing posture of recognizing oneself, and then can consciously overcome, and has reached the purpose of correcting student's mistake writing posture.And, in the utility model, at pen core 2 downwards the time, movable bolt 8 is because self gravitation is also downward, and bar magnet is resisted against in the radial groove 10 of movable bolt 8 for 9 this moments just, so, this activity bolt 8 is limited, and pen core 2 can't be withdrawn in the pen cap 1, writes reliably from can realizing.Only be when student's fault, this bar magnet 9 just can break away from radial groove 10, realizes the correction to student's mistake writing posture.With respect to prior art, posture-correcting pen described in the utility model is write more reliable.
