Abstract
The utility model discloses an instrument dial plate with a night vision function. The instrument dial plate with the night vision function comprises a dial and pointers installed on the dial. The dial comprises a light transmission portion and a lightproof portion. The pointers are made of materials with a light guide function. A light guide disc with a reflection function is arranged on a position, close to the dial, of the backside portion of the dial. A light source is installed on the light guide disc. After the light source on the light guide disc is switched on, the pointers and the light transmission portion of the dial are illuminated and carry out displaying. The instrument dial plate provided by the utility model can enable an instrument to be used normally in a dark environment.
Description
Technical field
The utility model relates to instrument field, more particularly, relates to a kind of instrument and meter dial plate with night vision function.
Background technology
Pointer-type instrument and meter is widely used in a lot of fields, such as, tensimeter, thermohygrometer, pointer clock, vehicle speed table etc.This class instrument does not have any obstacle while using by day, but to night or do not have, under environment that light illuminates, to be difficult to see the scale value of pointer indication, brings inconvenience to people's normal use.
Utility model content
For the technical matters existing in above-mentioned prior art, the utility model provides a kind of instrument and meter dial plate with night vision function, by simple structural design, meets the normal use under dark surrounds.
For achieving the above object, the technical scheme that the utility model adopts is as follows:
A kind of instrument and meter dial plate with night vision function, comprise index dial and be arranged on the pointer on index dial, described index dial comprises light transmission part and lightproof part, described pointer is made by the material with light-guiding function, at described index dial back, near described index dial position, be provided with a leaded light dish with diffusion function, on described leaded light dish, light source is installed, after light source igniting on described leaded light dish, demonstration is illuminated in the light transmission part on described pointer and described index dial.
The center of described leaded light dish offers a hole, the surrounding in described hole is provided with the light guide plate that a circle has reflection function, described light source is arranged on the outside of described light guide plate, one end of described pointer is positioned at the inner side of described light guide plate, after described light source igniting, through described light guide plate lateral wall, reflects to surrounding, illuminate the light transmission part on described index dial, from the light of described light guide plate transmission, irradiate to the pointer one end that is positioned at described light guide plate inner side, make described pointer light demonstration.
Light guide plate zone line on described leaded light dish is provided with trumpet-shaped opening.
The pitch angle, two side of the horn-like opening of described light guide plate is 45 degree.
Light source on described leaded light dish is form a circle a plurality of.
Described light source is LED.
Described pointer is more than one.
Light transmission part on described index dial is transparent or hollow out.
The instrument and meter dial plate with night vision function provided by the utility model, by leaded light dish being set at index dial back, on leaded light dish, light source is installed, the light guide plate that one circle has certain diffuse reflection and scattering function is set on leaded light dish, light guiding is had and on the pointer of light-guiding function and index dial, needs the place that shows, instrument can normally be used under dark environment.
Accompanying drawing explanation
Fig. 1 is instrument dial plate structural representation provided by the utility model;
Fig. 2 is the structural representation of instrument dial plate leaded light dish provided by the utility model;
Fig. 3 is that Fig. 2 is along the sectional view of A-A.
Embodiment
Below by specific embodiment, in conjunction with Figure of description, technical solutions of the utility model are further described.
Shown in Fig. 1～Fig. 3, the instrument and meter dial plate with night vision function provided by the utility model, comprises index dial 1 and is arranged on the first pointer 2 and the second pointer 3 on index dial 1.Index dial 1 comprises light transmission part 10 and lightproof part 11.The first pointer 2 and the second pointer 3 are made by the material with light-guiding function.At the back of index dial 1, the position of close index dial 1 is provided with a leaded light dish 4 with diffusion function.Light source 5 is installed on leaded light dish 4.After light source 5 on leaded light dish 4 is lighted, the light transmission part 10 on the first pointer 2, the second pointer 3 and index dial 1 is illuminated demonstration.
In the utility model embodiment, the light transmission part 10 on index dial 1 is word and scale value, and this light transmission part can be that transparent material is made, and can be also the structure of hollow out.The leaded light dish 4 at index dial 1 back is arranged on index dial 1 by two screws 9.Leaded light dish 4 has scattering and diffusion function, light can be shone out more uniformly.In the center of leaded light dish 4, offer a circular hole 5, for the first pointer 2 and the second pointer 3 are installed.The periphery of circular hole 5 is provided with a circle light guide plate 7.Light guide plate 7 has reflection function.LED light source 8 is installed in the outside of light guide plate 7, and this LED light source 8 is three that form a circle.After passing through by the supply socket 12 on leaded light dish 4, LED light source 8 is lighted, and light is irradiated to the outer rear flank of light guide plate 7, by reflecting to surrounding, thereby illuminates the light transmission part 10 on index dial 1.And the part light transmitting from light guide plate 7 is irradiated to one end of pointer, makes the pointer with light-guiding function illuminate demonstration.In order to improve the reflection efficiency of light, the zone line of light guide plate 7 is provided with trumpet-shaped opening.The pitch angle, two side of the horn-like opening of described light guide plate 7 is 45 degree.
The present embodiment is applicable in dual-needle, dual-tube manometer, thereby makes this tensimeter also can know and see pointer and surface clearly in dark surrounds, and effect is very obvious.
Above-described embodiment is only for illustrating the utility model; wherein the structure of each parts, connected mode etc. all can change to some extent; every equivalents of carrying out on the basis of technical solutions of the utility model and improvement, all should not get rid of outside protection domain of the present utility model.
