Abstract
The utility model relates to a nighttime ruler, belongs to the measuring device, comprising a ruler body. The utility model is characterized in that the ruler body is divided into two layers, the lower layer is provided with a scale which is the measuring layer, and the upper layer is the luminous layer. When the ruler is used on construction site at night, the reading error caused by dim light can be avoided. The nighttime ruler also can be used for field work, which can overcome the reading difficulty when the light is poor. The structure is simple and practical.
Description
Technical field
The utility model relates to a kind of measurer, specifically uses chi a kind of night.
Background technology
When carrying out field study or working at the construction field (site), need measure at night if run into special circumstances, want to read accurately measurement result and will compare difficulty, tend to make error to increase, if there is not standby light, measurement can't be carried out.
The utility model content
The purpose of this utility model is to provide uses chi a kind of night, and this ruler uses when night or ambient light are dark can be luminous, guarantees the accuracy of reading.
The technical scheme in the invention for solving the technical problem is: use chi a kind of night, comprises the ruler body, it is characterized in that, described ruler body is two-layer, below one deck indicate scale, be the tolerance layer, above one deck be luminescent layer.
The beneficial effects of the utility model are: cover one deck luminescent layer on the ruler surface, guarantee to see clearly the reading of ruler, when needing use evening at the construction field (site), can be because of avoiding the bad increase reading error of light, also can be used for field survey, overcome the reading difficulty of light when bad.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1 tolerance layer, 2 luminescent layers.
Embodiment
As shown in Figure 1.Use chi a kind of night, comprises the ruler body, it is characterized in that, described ruler body is two-layer, tolerance layer 1 and luminescent layer 2.Tolerance layer 1 is marked with scale, covers one deck luminescent layer 2 above tolerance layer 1.Luminescent layer 2 can adopt existing Noctilucent material, measure when night or ambient light are bad as need, thereby luminescent layer 2 can luminous assurance people can be seen the reading of ruler clearly, reduces error, improves the accuracy of reading, for the measurement at night provides convenience.The utility model is simple in structure, and is convenient and practical.
Claims (1)
1, use chi a kind of night, comprise the ruler body, it is characterized in that, described ruler body is two-layer, below one deck indicate scale, be the tolerance layer, above one deck be luminescent layer.
