Abstract

The utility model belongs to a scale which comprises a scale body made of transparent material. Graduation is arranged on the scale body, and the lower part of the graduation is provided with a groove, in which is provided with a light source generation body that is composed of an electric laser element. A terminal arranged on the light source generation body is connected with a power drive control device for providing the power supply which is needed by luminescence. The light source produced by the light source generation body is controlled by the power drive control device, and is penetrated through the scale body made of transparent material. The graduation of the scale body is clear and discernible, and is easy to read.

Description

A kind of rule

The utility model belongs to measure uses rule.

General rule adopts superfine scale usually in order to increase accurately and accuracy, if light is good, when sight line is good, really visually read errorlessly, but under the situation of insufficient light, use, then measure or will be quite painstaking when reading reading, therefore, the generation that makes the mistake easily.

The purpose of this utility model promptly can be controlled active illuminating providing a kind of by power drives, make when extraneous light is more weak, also reads the rule of scale easily.

The purpose of this utility model reaches like this: insert light source generation body in rule body inside, when light source generation body is driven the generation light source by the power drives control device, chi body through transparent material appears, chi body high scale is seen clearly easily, be that rule is configured to: it comprises the made chi body of a transparent material, on it and be provided with scale, below scale, offer groove, groove internal fixation one light source generation body, this light source generation body is made of the electric laser element, be connected with the power drives control device on it and by a terminal, so that luminous required power supply to be provided, and the light source that takes place can appear through the chi body of transparent material, makes chi body high scale be easier to see clearly.

Profile of the present utility model and known rule profile are very nearly the same, so do not account for unnecessary space, need not special skill on using again, and at insufficient light, or even do not have fully the illumination situation under, all can clearly read the scale on the chi body by the light source generator active illuminating, therefore, have and be easy to see clearly scale and easy to operate advantage.

The utility model is described in further detail below in conjunction with drawings and Examples:

Shown in Figure 1 is the three-dimensional exploded view of the utility model one preferable possible embodiments.

Shown in Figure 2 is the schematic perspective view of the utility model one preferable possible embodiments.

At first, see also shown in Figure 1ly, the utility model one preferable possible embodiments comprises a chi body 1 and a light source generation body 2, and wherein: this chi body 1 is made for general transparent material, and both sides are provided with scale 11 it on, all offer a groove 12 below scale.

This light source generation body 2, be mainly and comprise an electric laser element 21 (as being: ELECTRO LUMINESCENT LAMP is called for short EL), the electric conductor ITO (INDIUM TINOXIDE) that produces the electric laser effect is coated one deck glued membrane in skin to get final product, it is one laminar that this electric laser element 21 roughly is, its size shape is the internal capacity that cooperates set groove 12 on the chi body 1, and accepting to send light source when micro-power supply is supplied with, on it and a terminal 22 arranged, can be connected with power drives control device 23, this power drives control device 23 is general drive unit, inside includes battery 231, IC circuit 232 and transformer 233 etc., and by 234 controls of the switch on the power drives control device 23, provide the electric laser element 21 required power supplys, make and send light.

See also Fig. 2, when the utility model embodiment makes up, only the electric laser element 21 of light source generation body 2 must be fixed in the groove 12 on the chi body 1, utilize power drives control device 23 to be installed in an end of chi body 1 again, terminal 22 on the electric laser element 21 is inserted in the power drives control device 23, luminous by switch 234 control electric laser elements 21, see through the chi body 1 of transparent material, make the operator can observe scale 12 on the chi body 1 easily by the light source of its generation.

Claims

A kind of rule, comprise the chi body that a transparent material is made, on it and be provided with scale, it is characterized in that: below scale, offer groove, groove internal fixation one light source generation body, this light source generation body is made of the electric laser element, is connected with the power drives control device on it and by a terminal, so that luminous required power supply to be provided; The light source that light source generation body is produced by power drives control device control appears through the chi body of transparent material, and clear and legible being easy to of scale on the chi body read.
