Embodiment
According to creating conception of the present utility model, the utility model level meter can be realized respectively by two different embodiments, to be applied to the test of one dimension horizontal checkout and two-dimensional level respectively.Because principle of work is the same, the level meter that is used for the one dimension horizontal checkout is compared with the level meter that is used for the two-dimensional level test, and it is that component part reduces a spirit bubble and corresponding infrared, receiving trap quantity relatively.Therefore, following specific embodiment is the level meter that is used for the two-dimensional level test.
See also shown in Figure 1, the utility model level meter includes box body 1, lid 2, six groups of infrared transmitting devices 3, infrared receiver 4, two spirit bubbles 5, red led 6, green indicating lamp 7, triode 8, battery supply 9, resistance 10 and circuit boards 11 (also can be replaced by electric wire).Wherein be provided with receiving space 101 in the box body 1.Be symmetrical arranged five through holes, 201, one through holes 201 and be positioned at the center on lid 2, all the other four through holes, 201 relative central through hole 201 symmetries are positioned at all around to represent four orientation.Be provided with sealing host cavity 51 in the spirit bubble 5, in host cavity 51, be filled with black liquor 52 (also can be other light tight adopting dark liquids), also contain flowable bubble 53 in the host cavity 51.The length of bubble 53 is preferably 1/3rd of host cavity 51 length.Because infrared transmitting device 3, infrared receiver 4, spirit bubble 5, triode 8, battery supply 9, resistance 10, circuit board 11 are existing known elements, are not giving unnecessary details herein.
During assembling, six groups of infrared transmitting devices 3, infrared receiver 4, two spirit bubbles 5, red led 6, green indicating lamp 7, triode 8, battery supply 9, resistance 10 and circuit boards 11 all are contained in box body 1 receiving space 101.Wherein a spirit bubble 5 is horizontally disposed with, another spirit bubble 5 relative its vertical settings.Three groups of infrared and receiving trap 3,4 are set respectively near the middle part of each spirit bubble 5 both sides and the two ends thereof.Be positioned at two spirit bubbles, 5 both sides medium positions two groups of infrared, receiving trap 3,4 and triode 8, green indicating lamp 7, resistance 10, and battery supply 9 be connected in series by circuit board 11 and form first circuit, its circuit diagram as shown in Figure 2, this circuit also can be reduced to two circuit, as shown in Figure 3.Infrared, receiving trap 3,4 and the red led 6, the resistance 10 that are positioned at the spirit bubble end positions are connected in series by circuit board 12 and form four second circuits, its circuit diagram also as shown in Figure 3, also can be with circuit of four second circuits formation in parallel, because of it is that persons skilled in the art are known, no longer illustrate.After lid 2 is placed on receiving space 101 opening parts, outside green indicating lamp 7 is revealed in by central through hole 201, outside the red led 6 in corresponding each orientation is revealed in by through hole 201 around corresponding.
During work, when the bubble 53 of two spirit bubbles 5 all mediated, the two groups of infrared, the receiving trap 3,4 that are in two spirit bubbles, 5 both sides medium positions were connected, and the first circuit turn-on green indicating lamp is bright.When the bubble 53 of arbitrary spirit bubble 5 does not mediate, first circuit then can not conducting, green indicating lamp 7 does not work, at this moment, must there be a bubble 53 to flow to an end of a spirit bubble 5, make infrared, the receiving trap 3,4 be positioned at spirit bubble 5 these end both sides connect, and then make a second circuit conducting, a red led 6 is bright.If when the bubble 53 of two spirit bubbles 5 all is not positioned at the centre position, then should have two red leds bright mutually.The operator can make corresponding adjustment according to the indication of red light of expression different azimuth, till red light extinguishes green light and lights, so that level meter is in the two-dimensional level state.
Switchgear can be set with conserve batteries power supply 9 in first circuit and second circuit.The position of switchgear can be provided with arbitrarily as required.
Red led 6 also can be substituted by other indicating device of switching on shinny light-emitting device or energising sounding with green indicating lamp 7.As long as can difference level and non-standard state.Because alternative is known for persons skilled in the art, repeats no more herein.
In addition, those skilled in the art can do conversion according to creating conception of the present utility model, as with the bubble of spirit bubble in the embodiment during over against infrared transmitting device, circuit turn-on, indicating device produces indicative function, and the bubble of changing into spirit bubble is during over against infrared transmitting device, circuit turn-on, indicating device produces indicative function, and its circuit diagram as shown in Figure 4.
