Description
Technical field
The utility model relates to a kind of educational aid, specifically a kind of rotary-type laser pen.
Background technology
Existing laser pen can only show hot spot on blank or screen, can only play the effect of indicating positions.In modern teaching, not only require can indicating positions for classroom interaction more and more, also want to show in time " to ", the information such as " mistake ".Although computer PPT software can realize this function, it needs the support of computer hardware and related software, higher to equipment requirement, and traditional projector does not then possess this function.
Summary of the invention
The purpose of this utility model is to provide that a kind of structure is simple, the rotary-type laser pen of rich display information.
The technical scheme that the utility model adopts for technical solution problem is:
Rotary-type laser pen described in the utility model comprises columned shell, installs battery in the enclosure and laser head, described laser head is electrically connected with battery by wire and switch, the front end of shell is provided with lens, the sidewall of described case nose is provided with axle bed, and described axle bed is provided with the axis hole being parallel to housing axis; The center of wheel disc is provided with the rotating shaft be inserted in described axis hole, and described wheel disc is disc, and on wheel disc, twisted rotary shaft is uniformly distributed multiple filter hole, is provided with filter in described filter hole, and the wheel card outside described filter hole is provided with hemispheric lens.
The inwall of described axis hole is provided with the draw-in groove of annular, the outer wall of described rotating shaft is provided with the snap ring of coupling draw-in groove; The edge of described wheel disc is provided with the flanging extended to shell rear.
After adopting technique scheme, this laser pen is except can, by except hot spot display position information, projecting on screen by the symbolic information on filter, its structure is simple, rich display information, and realizes the switching of multiple symbolic information by changing filter.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
Fig. 2 is the planar structure schematic diagram of wheel disc.
Embodiment
As shown in Figure 1, rotary-type laser pen described in the utility model comprises columned shell 1, be arranged on battery 2 in shell 1 and laser head 3, described laser head 3 is electrically connected with battery 2 by wire and switch, the front end of shell 1 is provided with lens 4, laser head 3 can send laser when being energized, and scioptics 4 project on screen.
The sidewall of described shell 1 front end is provided with axle bed 5, and described axle bed 5 is provided with the axis hole being parallel to shell 1 axis; The center of wheel disc 6 is provided with the rotating shaft 7 be inserted in described axis hole, described wheel disc 6 is disc, on wheel disc 6, twisted rotary shaft 7 is uniformly distributed multiple filter hole, is provided with filter 8,9 in described filter hole, and the wheel card outside described filter hole is provided with hemispheric lens 4.
Filter 8,9 adopts different filter effects respectively, such as can arrange respectively as required as shown in Figure 2 without symbol filter, opaque background color representing the filter filter of " correctly ", opaque background color representing " mistake " with cross transparent region with check mark transparent region, these filters are corresponding to be respectively arranged in different filter holes; During use, different filters can be forwarded to the dead ahead of laser head by rotating wheel disk 6, and laser projection will symbol pattern on display filter to the hot spot on screen.
In addition, as further improvement of the utility model, the inwall of described axis hole is provided with the draw-in groove of annular, the outer wall of described rotating shaft 7 is provided with the snap ring of coupling draw-in groove, can prevent rotating shaft 7 accidental like this; The edge of described wheel disc 6 is provided with the flanging 10 extended to shell 1 rear, can facilitate rotating wheel disk.
