For achieving the above object, the utility model provides a kind of ruler, comprise ruler body, the head of described ruler body is provided with scale, also comprise battery, switch, installing plate and for providing the LED of light source to scale, described LED is arranged on described installing plate, and described battery, described switch and described LED are by wired in series, and described battery, described switch, described LED and described installing plate are installed on described ruler body.
Preferably, described battery, described switch, described LED and described installing plate are installed in the afterbody of described ruler body.
Preferably, also comprise protective cover, described battery, described LED and described installing plate are all located in described protective cover, and described switch is on described protective cover outside surface.
Preferably, described switch is arranged on the side of described protective cover.
Preferably, described protective cover and described ruler body removably connect.
Preferably, described LED is multiple, and multiple described LED equidistantly distributes along the length direction of described installing plate, and described installing plate extends to the two ends of described ruler body along the length direction of described ruler body.
Preferably, described battery is button cell.
Preferably, described ruler body is plastic, transparent ruler body.
In technique scheme, the ruler that the utility model provides comprises ruler body, battery, switch, installing plate and for providing the LED of light source to scale, the head of ruler body is provided with scale, LED is installed on a mounting board, battery, switch and LED are by wired in series, and battery, switch, LED and installing plate are installed on ruler body.When needs are more weak or when not having to use ruler when light source at some light-source brightness, user is by Push switch, and make LED luminous, for the scale place of ruler provides light source, user measures concrete length by ruler.
Known by foregoing description, in the ruler that the utility model provides, the LED of light source can be provided for the scale on ruler by arranging, even if make user more weak or there is no can accurately read when light source the reading of scale at light-source brightness.Therefore, the measurement accuracy of ruler that the application provides improves.
Accompanying drawing explanation
The structural representation of the ruler that Fig. 1 provides for the utility model embodiment.
Wherein in Fig. 1: 1-ruler body, 2-LED lamp, 3-switch, 4-battery, 5-installing plate, 6-protective cover.
Embodiment
Core of the present utility model is to provide a kind of ruler, and the measurement accuracy of this ruler improves.
In order to make those skilled in the art understand the technical solution of the utility model better, below in conjunction with drawings and embodiments, the utility model is described in further detail.
Please refer to Fig. 1, in a kind of embodiment, the ruler that the utility model provides comprises ruler body 1, battery 4, switch 3, installing plate 5 and for providing the LED (light emitting diode of light source to scale, light emitting diode) lamp 2, the wherein wiring board assembled for PCB hardboard of installing plate 5.The head of ruler body 1 is provided with scale, and LED 2 is arranged on installing plate 5, and battery 4, switch 3 and LED 2 pass through wired in series.Battery 4, switch 3, LED 2 and installing plate 5 are installed on ruler body 1, concrete, and battery 4, switch 3, LED 2 and installing plate 5 are installed in the side of ruler body 1.Battery 4 can be bar shaped dry cell or button cell etc., installs battery 4 and reduce the volume shared by battery 4 for the ease of staff, and the application is preferred, and battery 4 is button cell.Ruler body 1 is metal ruler body or plastic, transparent ruler body etc., and in order to improve ruler measurement accuracy, the application is preferred, and ruler body 1 is plastic, transparent ruler body.
When needs are more weak or when not having to use ruler when light source at some light-source brightness, user is by Push switch 3, and LED 2 is luminous, and for the scale place of ruler provides light source, user measures concrete length by ruler.
Known by foregoing description, in the ruler that the utility model specific embodiment provides, the LED 2 of light source can be provided for the scale on ruler, even if make user more weak or there is no accurately to read when light source the reading of scale at light-source brightness by arranging.Therefore, the measurement accuracy of ruler that the application provides improves.
Preferably, as shown in Figure 1, battery 4, switch 3, LED 2 and installing plate 5 are installed in the afterbody of ruler body 1.Because the afterbody of ruler body 1 is longer, be convenient to arrange battery 4, switch 3, LED 2 and installing plate 5, be convenient to staff and battery 4, switch 3, LED 2 and installing plate 5 are installed.
In the storage considering ruler and use procedure, LED 2, wire and battery 4 easily and extraneous contact cause its situation about damaging.In order to extend the serviceable life of ruler, this ruler also comprises protective cover 6, and battery 4, LED 2 and installing plate 5 are all located in protective cover 6, and switch 3 is arranged on protective cover 6 outside surface.Concrete, the division board against sunshine that protective cover 6 comprises transparent division board and is fixedly connected with described transparent division board, the scale on transparent division board and ruler body 1 is just right, and the upper surface of protective cover 6 is division board against sunshine, in use, the light source being convenient to LED 2 shines to scale ruler.Meanwhile, avoid the situation of the light source perturbation operation person eyes of LED 2, further increase the measurement accuracy of ruler.
