Abstract
The utility model discloses a laser-pen parallel light source, belonging to the field of physics teaching instrument. The laser-pen parallel light source structurally comprises a shell and pen holes, wherein 2-5 mutually parallel pen holes are arranged in the shell, glass rods are correspondingly inserted on the shell at the front ends of the pen holes, lens pens are placed in the pen holes, light points at the front ends of the pen holes are corresponding to the glass rods, and control buttons are arranged on the side surfaces of the laser pens. Compared with the prior art, the laser-pen parallel light source disclosed by the utility model has the characteristics of being reasonable in design, simple in structure, easy in machining, low in price, convenient in use, etc.
Description
Technical field
The utility model relates to the physics educational apparatus field, specifically the laser pen source of parallel light.
Background technology
The experimental apparatus of existing junior physics opticator mainly contains two kinds, and a kind of is optical bench, and another kind is an optical disk.These two kinds of instruments all must be furnished with source of parallel light.The luminophor of the source of parallel light of optical bench is 6 volts 8 watts a bayonet-type bulb.Must use student's light source during use, be 220 volts AC voltage conversion 6 volts DC voltage.The luminophor of the source of parallel light of optical disk is 12 volts 50 watts raw silk rings bulb or 6 volts 8 watts bayonet-type bulb, and use is to be equipped with Power supply for teaching, is 220 volts voltage transformations 12 volts DC voltage.These two kinds of bulbs all are special-purpose bulbs, in case damage, just can't change, and become waste product until instrument.
Summary of the invention
The technical assignment of the utility model is to above weak point, and a kind of laser pen source of parallel light simple in structure, cheap, easy to use is provided.
The utility model solves the technical scheme that its technical matters adopted: this laser pen source of parallel light comprises a housing and a hole; Be provided with a 2-5 hole that is parallel to each other in the housing; Correspondence is inlaid with glass bar on the front end shell in hole; Be placed with laser pen in the hole, the luminous point of laser pen front end is corresponding with glass bar, and the laser pen side is provided with control knob.
The bottom of described housing is provided with magnet.
The laser pen source of parallel light of the utility model is compared with prior art, have reasonable in design, simple in structure, be easy to processing, characteristics such as cheap, easy to use.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further specified.
Accompanying drawing is the structural representation of laser pen source of parallel light.
Among the figure: 1, housing, 2, a hole, 3, laser pen, 4, button, 5, glass bar, 6, magnet.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is described further.
The laser pen source of parallel light of the utility model, its structure comprise a housing 1 and a hole 2, and the bottom of housing 1 is provided with magnet 6, can housing 1 be fixed on the optical disk through magnet 6 and demonstrate; Be provided with two, three, four or five hole 2 that are parallel to each other in the housing 1; Be placed with laser pen 3 in the hole 2, can in a hole 2, insert the laser pen 3 of respective numbers as required, correspondence is inlaid with glass bar 5 on the front end shell 1 in a hole 2; The luminous point of laser pen 3 front ends is corresponding with glass bar 5; Make glass bar 5 can amplify light, laser pen 3 sides are provided with control knob 4, and button 4 can start laser pen under the compressing of a hole 2 hole walls.
Its processing and fabricating of laser pen source of parallel light of the utility model is very simple and convenient, and processing and fabricating gets final product shown in the by specification accompanying drawing.Not only be fit to student experimenting and use, also be fit to the teacher and demonstrate usefulness.
Except that the described technical characterictic of instructions, be the known technology of those skilled in the art.
