Abstract
The utility model discloses a kind of Simple spirit level, comprise that one is arranged on direct supply and the master switch on main line, be parallel to two test branch roads on direct supply on main line, in each test branch road, by a mercury cut-off and a light emitting diode, be in series, by mercury cut-off, light emitting diode and direct supply, form a test loop, during test, two mercury cut-offes are flatly positioned on same test surfaces.Simple spirit level of the present utility model is simple in structure, easily builds, and adopts two light emitting diodes and two mercury cut-offes, rather than traditional bubble indicates inclination, is not subject to the such environmental effects such as temperature, and test result is accurately stable.
Description
Technical field
The utility model relates to a kind of Simple spirit level, belongs to electronic technology field.
Background technology
Level meter is usually used in measuring equipment with respect to the degree of tilt of horizontal level, the horizontal level of the flatness of lathe kind equipment guide rail, equipment installation etc.Conventional is that level meter is air-bubble level at present, and its principle is that while utilizing bubble in glass tube, bubble remains on the characteristic of extreme higher position conventionally, by the bubble position scale determined level degree in glass tube.But air-bubble level is subject to the such environmental effects such as temperature, test result is unstable.
Utility model content
Technical problem to be solved in the utility model is the defect that overcomes prior art, and a kind of Simple spirit level is provided, and avoids being subject to the impact of environmental factor, stable testing.
For solving the problems of the technologies described above, the utility model provides a kind of Simple spirit level, it is characterized in that, comprise that one is arranged on direct supply and the master switch on main line, be parallel to two test branch roads on direct supply on main line, in each test branch road, by a mercury cut-off and a light emitting diode, be in series, by mercury cut-off, light emitting diode and direct supply, form a test loop, during test, two mercury cut-offes are flatly positioned on same test surfaces.
Described mercury cut-off is unidirectional mercury cut-off.
In unidirectional mercury cut-off, be packaged with noncontinuous electrode and a rotatable mercury bulb that a long electrode, curves certain angle, mercury bulb rolls between long electrode and noncontinuous electrode, whether determining electrode forms conductive path, only when the complete level of mercury cut-off, mercury bulb just contacts with long electrode and noncontinuous electrode simultaneously, make electrode form conductive path, mercury cut-off forms closure.
In unidirectional mercury cut-off, be packaged with two electrode and rotatable mercury bulbs that length is identical, only, when the complete level of mercury cut-off, mercury bulb is connected two electrodes to form conductive path, and mercury cut-off forms closure.
During test, closed master switch, if two surface maintenance levels that mercury cut-off is placed, two mercury cut-offes are all closed, the light emitting diode in two test loops is simultaneously luminous.
During test, closed master switch, can form conductive path and closure, the lumination of light emitting diode in the test loop at this mercury cut-off place if only have between the electrode of a mercury cut-off; The test surfaces at the mercury cut-off place that this is closed is higher than the test surfaces at another not closed mercury cut-off place.
The beneficial effect that the utility model reaches:
Simple spirit level of the present utility model is simple in structure, easily builds, and adopts two light emitting diodes and two mercury cut-offes, rather than traditional bubble indicates inclination, is not subject to the such environmental effects such as temperature, and test result is accurately stable.
Accompanying drawing explanation
Fig. 1 is Simple spirit level schematic diagram.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.Following examples are only for the technical solution of the utility model is more clearly described, and can not limit protection domain of the present utility model with this.
As shown in Figure 1, Simple spirit level of the present utility model comprises that one is arranged on direct supply U and the master switch S of the 3V on main line, be parallel to two test branch roads on direct supply U on main line, each is tested in branch road by a unidirectional mercury cut-off K1, K2 and a LED 1, LED2 is in series, by mercury cut-off K1, LED 1 and direct supply U form a test loop, by mercury cut-off K2, LED 2 and direct supply U form another test loop, two mercury cut-off K1 during test, K2 is flatly positioned on the same surface of test.
Simple spirit level of the present utility model adopts two LEDs 1, LED2 and mercury cut-off K1, K2, rather than traditional bubble indicates inclination, is not subject to the such environmental effects such as temperature.
Circuit is used two unidirectional mercury cut-off K1, K2, they respectively have a long electrode and a shorter noncontinuous electrode that curves certain angle, and rolled between long electrode and noncontinuous electrode by a mercury bulb, whether determining electrode forms conductive path, only when the complete level of mercury cut-off, mercury bulb just contacts with long electrode and noncontinuous electrode simultaneously, makes electrode form conductive path, and mercury cut-off forms closed communicating.
During test, closed master switch S, if the surface maintenance level of placing, between two mercury cut-off K1, K2 two electrodes separately, can form conductive path, otherwise only have between the electrode of a mercury cut-off and can form conductive path, if the surface of placing is tilted to the right, a mercury cut-off K1 electrode conduction wherein, LED 1 is luminous; If the surface of placing is tilted to the left, another mercury cut-off K2 electrode conduction wherein, LED 2 is luminous.If the surface level of placing, two mercury cut-off K1, the equal conducting of K2 electrode, LED 1, LED2 are simultaneously luminous.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; do not departing under the prerequisite of the utility model know-why; can also make some improvement and distortion, these improvement and distortion also should be considered as protection domain of the present utility model.
