Abstract
The utility model relates to a kind of teaching appliance, relates in particular to a kind of English stave projectoscope.It comprises casing, in described casing, be provided with support, it is characterized in that, on described support from front to after successively coaxial cable be provided with four line templates, condenser and projection bulb, the front side board of described casing is provided with projection convex lens, described projection convex lens outside is provided with light shield, and on described four line templates, level is provided with the transparent parallel lines of many groups, in described projection bulb, is connected with power lead.Described four line templates are arranged on described casing by slideway, described four line templates be rectangle, size is greater than the size of described condenser.Described four line templates are non-light-transmitting materials, and the transparent parallel lines of described many groups are hollow out line.The utility model structure is small and exquisite, utilizes projector principle projection four line lattice on blackboard fast, format specification; Write complete, powered-down, convenient and swift.
Description
Technical field
The utility model relates to a kind of teaching appliance, relates in particular to a kind of English stave projectoscope.
Background technology
In elementary English teaching, in order to write out the English of specification on blackboard, teacher wants first on blackboard, to draw four rulings, if drawn by ruler one rule, not only waste time and energy, and also lack of standardization.
Utility model content
The utility model, for above-mentioned the deficiencies in the prior art, provides a kind of and can be engraved in the English stave projectoscope that presents ruling on blackboard.
The technical scheme that the utility model solves the problems of the technologies described above is as follows: a kind of English stave projectoscope, comprise casing, in described casing, be provided with support, it is characterized in that, on described support from front to after successively coaxial cable be provided with four line templates, condenser and projection bulb, the front side board of described casing is provided with projection convex lens, described projection convex lens outside is provided with light shield, on described four line templates, level is provided with the transparent parallel lines of many groups, in described projection bulb, is connected with power lead.
The beneficial effects of the utility model are: its structure is small and exquisite, utilize projector principle projection four line lattice on blackboard fast, format specification; Write complete, powered-down, convenient and swift.
On the basis of technique scheme, the utility model can also do following improvement.
Further, described four line templates are arranged on described casing by slideway, described four line templates be rectangle, size is greater than the size of described condenser.
Adopt the beneficial effect of above-mentioned further scheme to be, the parallel lines spacing size that can be projected on blackboard by regulate four line template front and back positions to change along described slideway.To adapt to different teachers, the width requirement of different size blackboard to four line lattice.
Further, described four line templates are non-light-transmitting materials, and the transparent parallel lines of described many groups are hollow out line.
Adopt the beneficial effect of above-mentioned further scheme to be, can increase the relative brightness of four line lattice.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is four line template structural representations of the present utility model;
Fig. 3 is projection theory figure of the present utility model.
In Fig. 1～Fig. 3,1, projection convex lens; 2, four line templates; 3, support; 4, condenser; 5, projection bulb; 6, battery; 7, casing; 8, socket; 9, switch; 10, slideway; 11, dial handle; 12, blackboard.
Embodiment
Below in conjunction with accompanying drawing, principle of the present utility model and feature are described, example, only for explaining the utility model, is not intended to limit scope of the present utility model.
If Fig. 1 is to as shown in Fig. 3, a kind of English stave projectoscope, comprise casing 7, in described casing 7, be provided with support 3, on described support 3 from front to after successively coaxial cable be provided with four line templates 2, condenser 4 and projection bulb 5, the front side board of described casing 7 be provided with projection convex lens 1, described projection convex lens 1 outside is provided with light shield, on described four line templates 2, level is provided with the transparent parallel lines 2-1 of many groups, in described projection bulb 5, is connected with power lead.In described casing, be also provided with the rechargeable battery 6 of powering for described projection bulb 5, described rechargeable battery 6 connects charging socket 8; The top of described casing is also provided with switch 9.
Described four line templates 2 are arranged on described casing 7 by slideway 10, described four line templates 2 be rectangle, size is greater than the size of described condenser 4.Described casing 7 is provided with group handle 11 of stirring described four line templates 2.
Described four line templates 2 are non-light-transmitting materials, and the transparent parallel lines 2-1 of described many groups is hollow out line.
The utility model usage is as follows: the utility model is placed on dais, adjusts angle, press switch, the four line lattice that can obtain wanting on blackboard 12.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any amendment of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
