Abstract
The utility model discloses a plumb bob with an illuminating lamp and relates to the technical field of measuring instruments. The plumb bob consists of a plumb bob, a battery pack, a micro power supply switch, current limiting resistors and LEDs (Light Emitting Diodes), wherein the LEDs and the micro power supply switch are embedded in the plumb bob; a cavity is arranged in the plumb bob; and batteries and the current limiting resistors are arranged in the cavity. The cavity is formed inside the known plumb bob; the 3V button battery pack and four 10ohm current limiting resistors are arranged in the cavity; and two LEDs emitting white light are respectively embedded in the upper end and the middle of the plumb bob. When people carry out measuring work at night or under darker light, the four LEDs are energized to be lighten just by pressing the micro power supply switch on the plumb bob, white light emitted by the LEDs can illuminate a vertical line and can also illuminate a measuring point below the plumb bob so as to bring convenience to measuring work carried out by the people. The plumb bob with the illuminating lamp has the advantages of simpleness in manufacture, convenience in use and low cost.
Description
Technical field:
The utility model relates to measures the equipment technical field, the plumb bob that concrete is uses when a kind of people measure, especially a kind of plumb bob with illuminating lamp.
Background technology:
In surveying work, plumb bob has obtained using widely, and the plumb bob of various models and style brings great convenience to surveying work.But, if when night or light are very dark, use plumb bob to carry out surveying work, not only being difficult to see clearly vertical line, and being difficult to see clearly the measurement point below the plumb bob, this has just brought certain difficulty to surveying work.
Summary of the invention:
In order to overcome the deficiency that existing plumb bob exists, the utility model provides a kind of plumb bob with illuminating lamp.This plumb bob not only can be the same with existing plumb bob uses easily, and plumb bob carries illuminating lamp, can when night or light are very dark, for people use plumb bob to carry out surveying work illumination be provided.
The utility model solves the technical scheme that its technical matters adopted:
The utility model is described to be; A kind of plumb bob with illuminating lamp is made up of plumb bob, electric battery, micro power switch, current-limiting resistance and LED, and LED, micro power switch are inlaid on the plumb bob; A cavity is arranged in the plumb bob, battery and current-limiting resistance are installed in the cavity.
In the inside of known plumb bob, produce a cavity, the current-limiting resistance of 3 volts button cell groups and four 10 ohm is installed in the cavity, respectively be embedded with two LED that emit white light in the upper end of plumb bob respectively with middle.
In circuit, battery anode connects an end of micro power switch, the other end of micro power switch; Connect an end of four 10 ohm of current-limiting resistances; The other end of four 10 ohm of current-limiting resistances is connected on respectively on the positive pole of four LED, and the negative pole of LED is connected on the negative pole of electric battery.
When people when night or light are very dark carry out surveying work when using plumb bob; As long as press the micro power switch on the plumb bob; Circuit is connected, and four LED will get electric igniting, and the white light that LED sends not only can illuminate vertical line; But also can shine the measurement point below the plumb bob, for carrying out surveying work, people provide convenience.
The beneficial effect of the utility model is:
The plumb bob of band illuminating lamp not only can be the same with common plumb bob uses easily, and plumb bob carries illuminating lamp, can when night or light are very dark, for people carry out surveying work illumination be provided.The band illuminating lamp plumb bob easy to use, manufacture simple, with low cost.
Description of drawings:
Below in conjunction with accompanying drawing and embodiment the utility model is further specified:
Fig. 1 is the synoptic diagram that the utility model shows empty cavity position;
Fig. 2 is the synoptic diagram of the utility model;
Fig. 3 is the circuit diagram of the utility model.
Among the figure: 1. plumb bob, 2. cavity, 3～6. current-limiting resistances, 7. electric battery, 8. vertical line, 9. micro power switch, 10～13.LED.
Embodiment:
In the drawings; In the inside of known plumb bob 1, produce a cavity 2, the current-limiting resistance 3～6 of 3 volts button cell groups 7 and four 10 ohm is installed in the cavity 2; Be embedded with LED10,11 in the upper end of plumb bob 1, be embedded with LED12,13 in the centre of plumb bob 1.
In circuit, electric battery 7 positive poles connect an end of micro power switch 9, the other end of micro power switch 9; Connect an end of current-limiting resistance 3～6; The other end of current-limiting resistance 3～6 connects the positive pole of LED10～13 respectively, and the negative pole of LED 10～13 connects the negative pole of electric battery 7.
When people when night or light are very dark carry out surveying work when using plumb bob 1; As long as press the micro power switch 9 on the plumb bob 1; Circuit is connected, and LED10～13 will get electric igniting, and the white light that send LED10～13 not only can illuminate vertical line 8; But also can shine the measurement point of plumb bob 1 below, for carrying out mapping operations, people provide convenience.
