Description

The laser designator new construction

The utility model relates to a kind of laser designator, refers to a kind of adjustable focal length especially, the laser designator of the dissimilar convex lens devices that can change the outfit.

Common in the market a kind of laser pen, its inside is provided with semicondcutor laser unit, after a gauge tap energized, light emitting diode or pilot lamp set on the shaft of a writing brush can be shinny, semicondcutor laser unit can produce laser, laser is again via producing a luminous point behind the convex lens device, indication blackboard, blank or transparency, lantern slide use when being available for users to give a lesson or giving a lecture, but its structural defective causes following problem:

1, its convex lens device is located at the tip of the brushstyle of a writing or painting, and the user can't adjust voluntarily.

2, the focusing between convex lens device and semicondcutor laser unit is difficult for, and causes to make the fraction defective height.

3, the convex lens device can't be replaced, and practicality is not high.

4, the size of luminous point can't change, and can't adjust to desirable spot definition when different distance.

5, light emitting diode or pilot lamp need the power supply can be shinny, so must connect with the internal circuit device, not only manufacture is loaded down with trivial details, and expends electricity, the failure rate height.

6, its power consumption, luminous intensity are different with the laser diode in the semicondcutor laser unit, and also, even during the luminance shortage of laser diode, this light emitting diode or pilot lamp still can be shinny, can't truly reflect the bull bear position of true laser.

7, its gauge tap is to adopt simple driving or push type, forgets after driving then often produce to use and shuts if adopt, and expends; If adopt push type, the user in use need keep posture, effort and the inconvenience of pushing.

8, the output intensity of laser can't be adjusted.

Another kind of common semiconductor laser indicator, it mainly comprises: laser body, projection main body, cap bag group semicolumn mirror, wherein, the loam cake place of laser body is provided with power knob and power lights, bottom is provided with double faced adhesive tape, and after pressing the power knob energized, the projection main body is sent and projected a sign straight line after laser beam sees through the interior semicylinder of cap bag group, change the cap bag group and do thick, the fine control in line footpath, so its structural disappearance causes following problem:

1, changes the cap bag group and do thick, the fine control in line footpath and need possess many group cap bag groups, do not conform to economy, the cost height.

2, its power knob is manually control, so forget switching after normal generation is used, expends electric power.

3, its power lights need power supply can be shinny, so must connect with the internal circuit device, not only manufacture is loaded down with trivial details, and expends electricity, the failure rate height.

4, the manufacturing of semicolumn mirror, cut and grind, processing be difficult for and cost high.

5, laser projections can cause the phenomenon of part light reflection diffusion, so optically focused is not good when the plane of semicolumn mirror.

6, the output intensity of laser can't be adjusted.

The purpose of this utility model is to provide a kind of and can adjusts focusing voluntarily and be easy to replace the convex lens device, and can adjust and show the laser designator new construction of laser intensity, to overcome above-mentioned defective.

The laser designator new construction that the utility model proposes, mainly by a convex lens device, pipe before one, one laser aid, one back pipe, one bonnet constitutes, this convex lens device end is provided with the front end of the thread segment of a suitable length for pipe before being screwed on, inside is provided with a convex lens, the terminal inside of pipe before laser aid is located in, laser aid mainly is by the semiconductor laser aid, one circuit board, one gauge tap constitutes, be provided with a spring at the circuit board end, in the end of pipe was coated on laser aid before back pipe was screwed on, it is terminal that bonnet is screwed on the back pipe by its inboard set thread segment.Convex lens device inside has screwed togather convex lens ring and set collar, relative position between convex lens ring and laser semiconductor preestablishes to be adjusted to laser spot is as the criterion behind the burnt state, screwing in the set collar sealing again fixes, on the outer shroud of convex lens device, be provided with a directrix scale, also be provided with a directrix scale on the preceding pipe, when rotation convex lens device aligns directrix scale set on directrix scale set on the aforementioned convex lens device and the preceding pipe, be the accurate burnt state between semiconductor laser aid and convex lens, be convenient to user's focusing, moreover, the pipe shaft appropriate location of preceding pipe is provided with a lamp guide in order to be guided out the part of laser beam periphery circle, with the indication luminance, set gauge tap is a gauge tap that promotes and push double-purpose on its laser aid.
