Abstract
The utility model relates to a steel tape with an illuminating lamp, relating to the technical field of measurement tools. The steel tape consists of a steel tape, a battery pack, a mini power supply switch, a current-limiting resistor and LEDs (Light Emitting Diodes), wherein a cavity is arranged on a tape box of the steel tape, the mini power supply switch and the LEDs are embedded in the cavity, and the cavity is provided with the battery pack and the current-limiting resistor. The cavity is manufactured at the upper end of the tape box of the steel tape, and the mini power supply switch and the two LEDs emitting white lights are embedded in the cavity; and the battery pack and the current-limiting resistor are arranged in the cavity. When a person utilizes the steel tape to measure at night or in dim light, the two LEDs lighten electrically as long as the mini power supply switch is pushed down, and the bright LEDs can lighten scale number of an exist of the steel taper so that the person can read the measurement data. The steel tape with the illuminating lamp, disclosed by the utility model, has the advantages of convenience for using, simple manufacturing and low cost.
Description
Technical field:
The utility model relates to survey instrument articles for use technical field, the steel tape that uses during a kind of people's Measuring Object that concrete is, especially a kind of steel tape with illuminating lamp.
Background technology:
In people's routine work and life, steel tape has arrived use more and more widely, and the steel tape of various styles and function is easy to carry, easy to use, brings great convenience to people's surveying work.But, if when night or light are very dark, use steel tape to carry out surveying work, just being difficult to see clearly the mark number of size on the chi band, this just causes certain difficulty to people's surveying work.
Summary of the invention:
In order to overcome the deficiency that existing steel tape exists, the utility model provides a kind of steel tape with illuminating lamp.This steel tape not only can be the same with known steel tape uses easily, and steel tape carries illuminating lamp, can when night or light are very dark, for people 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 steel tape with illuminating lamp is made up of steel tape, electric battery, micro power switch, current-limiting resistance and LED, and a cavity is arranged on the chi box of steel tape; Micro power switch, LED are inlaid on the cavity, and electric battery and current-limiting resistance are installed in the cavity.
Under the condition of structure that does not change known steel tape and technical feature, in the upper end of steel tape chi box, produce a cavity, the micro power switch is inlaid on the cavity, be inlaid in two LED that emit white light the front end of cavity; The current-limiting resistance of 3 volts button cell groups and two 10 ohm is installed in the cavity.Lead links together electric battery, micro power switch, current-limiting resistance and LED.
In circuit, battery anode connects an end of micro power switch, the other end of micro power switch; Connect two 10 ohm current-limiting resistance; The other end of two 10 ohm of current-limiting resistances is connected on respectively on the positive pole of two LED, and the negative pole of LED connects the negative pole of electric battery.
When people use steel tape to measure when night or light are very dark; As long as press the micro power switch, circuit is connected, two LED will get electric igniting; The LED that ignites can illuminate the mark number that chi is taken out of mouthful, for people read measurement data illumination is provided.
The beneficial effect of the utility model is:
The steel tape of band illuminating lamp not only can be the same with known steel tape uses easily, and steel tape carries illumination, can when night or light are very dark, for people carry out surveying work light be provided.The band illuminating lamp steel tape 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 cavity;
Fig. 2 is the synoptic diagram of the utility model;
Fig. 3 is the circuit diagram of the utility model.
Among the figure: 1. chi box, 2. cavity, 3. electric battery, 4～5. current-limiting resistances, 6. micro power switch, 7～8.LED, 9. chi band.
Embodiment:
In the drawings,, produce a cavity 2, micro power switch 6 is inlaid on the cavity 2, be inlaid in the LED7 that emits white light～8 front end of cavity 2 in the upper end of steel tape chi box 1; 3 volts button cell groups 3 and current-limiting resistance 4～5 are installed in the cavity 2.
In circuit, electric battery 3 positive poles connect an end of micro power switch 6, and the other end of micro power switch 6 connects current-limiting resistance 4～5, and the other end of current-limiting resistance 4～5 is connected on respectively on the positive pole of LED7～8, and the negative pole of LED 7～8 connects the negative pole of electric battery 3.
When people use steel tape to measure when night or light are very dark; As long as press micro power switch 6, circuit is connected, LED7～8 will get electric igniting; The LED7 that ignites～8 can be illuminated the mark number of chi band 9 outlets, for people read measurement data illumination are provided.
