Abstract
The invention discloses a simple level gauge. The simple level gauge comprises a direct current power supply, a main switch and two testing branch circuits, wherein the direct current power supply and the main switch are arranged on a main circuit, and the two testing branch circuits are connected to the direct current power supply on the main circuit in parallel; a mercury switch and a light emitting diode are connected in series in each testing branch circuit, namely the mercury switch, the light emitting diode and the direct current power supply form a testing loop, and the two mercury switches are horizontally placed on the same testing surface in a testing process. The simple level gauge has the beneficial effects that the structure is simple and is easy to construct; the two light emitting diodes and the two mercury switches, rather than traditional bubbles, are used for indicating the inclination, so that the simple level gauge is unlikely to be influenced by environmental factors such as temperature, and a test result is stable and accurate.
Description
Technical field
The present invention relates to a kind of Simple spirit level, belong to electronic technology field.
Background technology
Level meter is usually used in measuring equipment with respect to the degree of tilt of horizontal level, flatness, the horizontal level that equipment is installed etc. of lathe kind equipment guide rail.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.
Summary of the invention
Technical matters to be solved by this invention 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 invention 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, be in series by a mercury cut-off and a light emitting diode, form a test loop by mercury cut-off, light emitting diode and direct supply, when 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 in the time of 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, in the time of the complete level of mercury cut-off, mercury bulb is connected two electrodes to form conductive path, and mercury cut-off forms closure.
When 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.
When 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 this closed mercury cut-off place is higher than the test surfaces at another not closed mercury cut-off place.
The beneficial effect that the present invention reaches:
Simple spirit level of the present invention is simple in structure, easily builds, and adopts two light emitting diodes and two mercury cut-offes, instead of traditional bubble indicates inclination, is not subject to the such environmental effects such as temperature, and test result is accurately stable.
Brief description of the drawings
Fig. 1 is Simple spirit level schematic diagram.
Embodiment
Below in conjunction with accompanying drawing, the invention will be further described.Following examples are only for technical scheme of the present invention is more clearly described, and can not limit the scope of the invention with this.
As shown in Figure 1, Simple spirit level of the present invention 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, in each test 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 when test, K2 is flatly positioned on the same surface of test.
Simple spirit level of the present invention adopts two LEDs 1, LED2 and mercury cut-off K1, K2, instead of traditional bubble indicates inclination, is not subject to the such environmental effects such as temperature.
Circuit uses 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 in the time of 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.
When 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, 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 the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, do not departing under the prerequisite of the technology of the present invention principle; can also make some improvement and distortion, these improvement and distortion also should be considered as protection scope of the present invention.
