Description
Technical field
The utility model relates to a kind of drive unit that is applied to propelled pen work, is applied to propelled pen.
Background technology
Now invent socially and a kind ofly cause near-sighted Nearsightedness-preventing pen in order to prevent user from using pen at light in the not good and not reciprocity situation of posture, but the internal driving mechanism more complicated of existing Nearsightedness-preventing pen, huge structure, for the less pen container of volume own, can additionally increase undoubtedly pen container volume, use and brought very big inconvenience to user like this.Therefore, for the problems referred to above be the object of the utility model research.
Utility model content
The purpose of this utility model is to provide a kind of drive unit that is applied to propelled pen work, contributes to solve the problems such as current propelled pen pen container volume is large, use inconvenience.
The technical solution of the utility model is:
A kind of drive unit that is applied to propelled pen work, comprise the shell of being located in handwriting, it is characterized in that: also comprise that the micro motor be located at outside shell is connected with the intermediate transmission assembly in being located at shell by micro motor in order to drive the mobile piston of refill expansion.
Wherein, described intermediate transmission assembly comprises the first gear train, the second gear train and the 3rd gear be located in shell, described the first gear train is rotated by the worm drive being connected on micro motor output shaft, described the 3rd gear is connected with a joggle through the second gear train and the first gear train, on one side end face of described the 3rd gear, Eccentric-hinge is connected to one end of a connecting rod, and the other end and the mobile piston of described connecting rod are hinged.
Described the first gear train is the first gear shaft of installing in shell and having two gears of size, and described the second gear train is the second gear shaft of installing in shell and having two gears of size, and the first gear shaft and the second gear shaft be arranged in parallel.
The gear wheel of described the first gear shaft is connected with worm engaging, and the gear wheel of the pinion of described the first gear shaft and the second gear shaft is connected with a joggle, and the pinion of described the second gear shaft engages with the 3rd gear.
Described shell be provided with two respectively when mobile piston stretches out and retract while reaching the limit of can autostop limit switch.
The utility model has the advantage of: the utility model frame for movement is simple, and driving relationship is reliable, and volume is small and exquisite, can effectively meets the demand that pen container own vol is less, meet user's instructions for use.
Accompanying drawing explanation
Fig. 1 is the overall perspective view of the utility model embodiment.
Fig. 2 is the mobile piston retracted mode structural representation of the utility model embodiment.
Fig. 3 is that the mobile piston of the utility model embodiment stretches out status architecture schematic diagram.
The specific embodiment
For above-mentioned feature and advantage of the present utility model can be become apparent, special embodiment below, and coordinate accompanying drawing, be described in detail below.
With reference to figure 1, Fig. 2 and Fig. 3, the utility model relates to a kind of drive unit that is applied to propelled pen work, comprise the shell 1 of being located in handwriting, also comprise that the micro motor 2 be located at outside shell is connected with the intermediate transmission assembly in being located at shell by micro motor in order to drive the mobile piston 3 of refill expansion.
Above-mentioned intermediate transmission assembly comprises the first gear train 4, the second gear train 5 and the 3rd gear 6 be located in shell, described the first gear train drives rotation by the worm screw 7 being connected on micro motor output shaft, described the 3rd gear is connected with a joggle through the second gear train and the first gear train, on one side end face of described the 3rd gear, Eccentric-hinge is connected to one end of a connecting rod 8, and the other end and the mobile piston of described connecting rod are hinged.
Above-mentioned the first gear train is the first gear shaft of installing in shell and having two gears of size, and described the second gear train is the second gear shaft of installing in shell and having two gears of size, and the first gear shaft and the second gear shaft be arranged in parallel.
The gear wheel of above-mentioned the first gear shaft is connected with worm engaging, and the gear wheel of the pinion of described the first gear shaft and the second gear shaft is connected with a joggle, and the pinion of described the second gear shaft engages with the 3rd gear.
Above-mentioned shell be provided with two respectively when mobile piston stretches out and retract while reaching the limit of can autostop limit switch 9.
Specific implementation process of the present utility model: the utility model in use, drive micro motor, make micro motor pass through worm drive the first gear train, then drive the 3rd gear to rotate by the second gear train, because Eccentric-hinge on a side end face of the 3rd gear is connected to a connecting rod, along with the rotation of the 3rd gear, can make connecting rod driven plunger stretching motion, thereby order about pen core return or stretch out pen container, completing executing agency's operation of propelled pen.
The limit switch arranging under this structure is bound bit switch, such object be that to trigger upper limit switch when guaranteeing that piston reaches top automatically out of service or to trigger limit switch while being retracted into bottom automatically out of service, such structure can effectively guarantee the each best pen core position of writing arranging that all accurately arrives of the pen core of piston driving, and simple of the control of motor needs a forward current, all the time direction operation just can, control circuit is simplified in a large number.
Occur in addition causing piston and gear to occur after dislocation special circumstances because of improper use, interim power-off etc., as long as continue to provide normal forward electric current, motion runs to bound bit switch place naturally to be stopped, and realizes self-adjusting correct position, without manually manually adjusting.
Bound bit switch can adopt different limit switch devices to realize according to the outward appearance of product, and upper figure uses 2 touch-switch to realize now, also can adopt leaf to touch switch, upper and lower contact chip form, photoelectric coupling and open the light etc.
The foregoing is only preferred embodiment of the present utility model, all equalizations of doing according to the utility model claim change and modify, and all should belong to covering scope of the present utility model.
