Embodiment Construction

[0013] refer to Figure 1 to Figure 2 Further description will be made to the ruler embodiment of the present invention with its own light.

[0014] Such as figure 1 with figure 2 The shown ruler with its own light includes a ruler body 1 made of transparent plastic. The ruler body 1 includes three layers, a surface layer 13 , an intermediate layer 12 and a bottom layer 11 . The scale 2 is arranged between the surface layer 13 and the intermediate layer 12 . It can well prevent the wear of the scale 2 during use, so that the service life of the ruler is longer.

[0015] In this embodiment, the core setting is exactly the led lamp 4 and the button battery 3 arranged on the middle layer 12 and the copper wire 5 connecting the led lamp 4 and the button battery 3 together. On the copper wire 5, set There is a break, so that the entire circuit will not be in a conductive state all the time. And the upper surface of the ruler body 1 is provided with a circular opening 6 at the...

Abstract

The invention discloses a ruler with lamplight. The ruler comprises a ruler body. Scales are arranged on the ruler body. The ruler body is transparent. The ruler body comprises a bottom face layer, a middle layer and a surface layer. A button cell, an led lamp and a plurality of copper strip wires are arranged in the middle layer. A circuit loop is formed by the button cell, the led lamp and the copper strip wires. Any copper strip circuit in the loop is cut off. An opening is formed in the surface layer and formed in the cut-off position of the corresponding copper strip wire so that the cut-off position of the copper strip wire can be completely covered. The ruler with lamplight is provided.

Description

technical field [0001] The invention relates to a measuring tool, more specifically, it relates to a ruler with a light. Background technique [0002] Straightedge is a common measuring tool with accurate straight edges, used for measuring length and drawing, and is widely used in mathematics, surveying, engineering and other disciplines. [0003] Ordinary rulers are all set as flat cuboids with scales on the edges of their surfaces, so that they can be measured well. However, in some special cases, such as in some dark corners, or in poor light conditions, the user cannot clearly read the reading on the surface of the ruler. In this case, the ordinary ruler cannot be used well, and it is necessary to find another light source, which is very troublesome. Contents of the invention [0004] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide a ruler with its own light. [0005] In order to achieve the above object, the present i...
