Abstract
The utility model relates to a multifunctional ruler, which not only solves the problem that a circle drawn with the compasses is inconvenient to measure while to carry a pencil, compasses and a protractor is also inconvenient, but also solves the problem that hand-painted symbols of electronic components are difficult to identify. The utility model is characterized in that hollowed-out common electronic component symbols are arranged on the main ruler; the left part of a semicircle protractor which can measure angles is provided with a central pen hole which is matched with a central pen hole on a slide bock to draw an arc or circle with required radius, and a pencil can be arranged between the pen groove of the main ruler and the slide block. Compared with an ordinary ruler, the ruler has the functions of holding a pencil, drawing the arc or circle with required radius, measuring angles and drawing electronic component symbols, and is applied to schools, factories, homes and the like.
Description
Technical field
The utility model relates to a kind of multifunctional ruler, especially can place pencil, draw required radius circular arc or circle, take measurement of an angle, draw the multifunctional ruler of electronic component symbol.
Background technology
Chinese patent disclosed " 200820011136.2 " " multipurpose ruler ", " 200820026964.3 " " multi-functional ruler ", " 200720024021.2 " " multipurpose ruler " all have innovation advantage separately.
Summary of the invention
The utlity model has the innovation distinct advantages different with it.The utility model is a kind of multifunctional ruler, can place easily pencil, accurately draw required radius circular arc or circle, take measurement of an angle, electronic component symbol commonly used can also standard draws.
The new solution that its technical problem that solves the utility model adopts is: the multifunctional ruler of being made up of main scale, slide block, semicircular protractor.Described main scale (2) is provided with a slide block (5) and can laterally moves along guide rail (3), slide block (5) is crossed slide block fixing hole (7) activity by slide block nut (9) and slider nut (10) and is fixed on the main scale (2), main scale (2) zero graduation line bottom is provided with a hole, the center of circle (1), the reading opening (6) on slide block (5) top has a radius hole (8), described main scale (2) right part has incorporate semicircular protractor (4), and the interior hollow out of a groove (21) that main scale (2) bottom is offered has triode (11), operational amplifier (12), diode (13), bi-directional voltage stabilizing diode (14), not gate (15), or door (16), with door (17), big resistance (18), electric capacity (19), small resistor (20) shape.Described slide block (2) uses the high resiliency transparent plastic to make.Distance is 2-5mm between a described slide block (2) and the groove (21).
The beneficial effects of the utility model are, this multifunctional ruler, the circle of required radius very easily can draw, and by the drawn radius of circle of the accurate control in the reading hole on the slide block, circuit common component symbol fast can draw again, can accurately take measurement of an angle, a groove of putting pencil is arranged, make things convenient for, save time, make simply, be easy to promote.
Description of drawings
Fig. 1 is the structural representation of the utility model ruler.
Among the figure 1, a hole, the center of circle 2, main scale 3, guide rail 4, semicircular protractor 5, slide block 6, reading hole, 7, slide block fixing hole 8, a radius hole 9, slide block nut 10, slider nut 11, triode 12, operational amplifier 13, diode 14, bi-directional voltage stabilizing diode 15, not gate 16 or door 17, with door 18, big resistance 19, electric capacity 20, small resistor 21, a groove
The specific embodiment
Below in conjunction with drawings and Examples to using novel being described further.
In Fig. 1, by main scale (2), slide block (5), the multifunctional ruler that semicircular protractor (4) is formed. main scale (2) is provided with a slide block (5) and can laterally moves along guide rail (3), slide block (5) is crossed slide block fixing hole (7) activity by slide block nut (9) and slider nut (10) and is fixed on the main scale (2), main scale (2) zero graduation line bottom is provided with a hole, the center of circle (1), can be used to demarcate the center of circle, the reading opening (6) on slide block (5) top has a radius hole (8), the circular arc or the circle that cooperate the required radius that to draw with a hole, the center of circle (1), described main scale (2) right part has incorporate semicircular protractor (4), the interior hollow out of a groove (21) that main scale (2) bottom is offered has triode (11), operational amplifier (12), diode (13), bi-directional voltage stabilizing diode (14), not gate (15), or door (16), with door (17), big resistance (18), electric capacity (19), small resistor (20) shape. described slide block (2) uses the high resiliency transparent plastic to make. and distance is 3-4mm between a described slide block (2) and the groove (21), the convenient pencil of placing.
