Abstract
The utility model discloses a horizontal-position electronic balance display. The utility model is characterized in that patch light-emitting diodes with very low electricity consumption are adopted; and a piezoelectric buzzer can be driven by enlarging a triode; each patch light-emitting diode is in series connected with a respective patch resistor and then in series connected with a mercury switch which can perceive the respective direction, and finally is connected to a general switch, thereby forming a simple loop. Since the piezoelectric buzzer is connected with a main circuit, once the leaning happens in any direction or plural directions, the corresponding mercury switch is conducted, and patch light-emitting diodes begin shinning to point to the unbalanced direction, meanwhile, the buzzer sounds a warning to remind of an unbalanced state.

Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
As shown in Figure 1, be structural representation of the present utility model, described rack section comprises that circuit board 1 is fixed on the upper end of pillar 7, and the lower end of pillar 7 is installed on the base plate 10, the plane parallel of circuit board 1 and base plate 10, the upper end of pillar 7 are equipped with nut 8 and pad 9.
As shown in Figure 2, it is the circuit diagram of an embodiment of the utility model, comprise that power supply 6 is connected in series with master switch 11, master switch 11 is connected in series with the positive input of diode 13 and variable resistor R14 respectively, diode 13 and variable resistor R14 are installed in parallel in circuit, the output terminal of the output terminal of diode 13 and variable resistor R14 is connected with two input ends of triode 3 respectively, the output terminal of triode 3 is connected with piezoelectric buzzer 4, patch light-emitting diode 2, Chip-R 12, mercury cut-off 5 threes connect successively and have eight groups, be connected in parallel between each group, and on circuit board 1, be symmetry and install, the input end of every group patch light-emitting diode 2 is connected with piezoelectric buzzer 4, and outlet one end of every group mercury cut-off 5 all takes back power supply 6 and constitutes the loop.
The utility model has adopted small mercury cut-off, and this mercury cut-off has the characteristic of the unidirectional energized with change in location.In order in time to carry out the indication and the response in a plurality of orientation with the variation of horizontal level, the utility model has adopted a plurality of mercury cut-offes by circumference symmetric offset spread successively, when the circuit board of fixing these mercury cut-offes not in horizontality, when one or more directions are on the low side, corresponding mercury cut-off is because the change of equilibrium position makes circuit disconnect, and connected light emitting diode and hummer are not indicated; But the mercury cut-off of higher direction correspondence is owing to circuit is connected in the change of equilibrium position, and connected light emitting diode and buzzer warning are indicated, thereby have realized the equilibrium position is indicated.
The utility model realizes that the key of precision control has two aspects:
The first, the symmetric offset spread of switch and level are installed.Existing miniature mercury cut-off, its external form mostly are cylindrical greatly, should not directly be used in this device, can order precision within limits and installed surface be that the mercury cut-off on plane is used for this device, to guarantee precision, reduce cost.The symmetric offset spread of so-called mercury cut-off in order to indicate unbalanced accurate direction, can be provided with some groups of mercury cut-offes exactly.
The second, the horizontal support of circuit board and base plate.The horizontal indicating status of circuit board is exactly the horizontality of base plate, and the horizontality of measuring basis face just is so must guarantee the plane parallel of base plate and circuit board.
Specific embodiment one:
