Abstract
The utility model relates to a luminous mark post. The utility model is characterized in that a ruler body of the utility model is a hollow quadrangular prism, one side of the ruler body is provided with an organic glass plate coated with red and white scales, and the cavity of the ruler body is provided with a closed lighting circuit which is composed of a lead battery, a switch and a bulb. When the utility model is used at night, the switch can be turned on.
Description
The utility model relates to a kind of measurement apparatus that is used to refer to measurement point.
At present, known mark post is many to be made with rod, scribbles scale mark red and white above.This mark post is owing to lack the noctilucence device, thereby can't use at night.
The purpose of this utility model is that a kind of Luminous surveyors' staff will be provided, and it not only can use by day, and because it has light-emitting device, so also can use at night.
The purpose of this utility model be achieved in that with the mark post body make the four prism type of hollow, a prismatic side is the poly (methyl methacrylate) plate with scale, and power supply, switch and an a series of bulb are installed in the mark post.Like this, just can open switch when use night, make bulb luminous, the red white scale on the organic glass is manifested.
Owing to adopt such scheme, can use the utility model at night, this has just remedied the shortcoming of known mark post, therefore the utlity model has positive effect.
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is circuit theory diagrams of the present utility model.
Fig. 2 is the longitudinal profile structural map of the utility model embodiment.
Among the figure 1, chi body 2, poly (methyl methacrylate) plate 3, lead accumulator 4, bulb 5, switch
In Fig. 1, connect with switch (5) and lead accumulator (3) in bulb (4) back in parallel.
In the embodiment shown in Figure 2,, inlay a poly (methyl methacrylate) plate (2) that scribbles the black and white scale, in the cavity of chi body, lead accumulator (3), bulb (4), switch (5) that order is electrically connected are installed in a side of hollow four prism type chi body (1).The outer end of switch (5) is exposed at the surface of chi body (1).As long as open switch (5), make bulb luminous, just can use at night.
Claims (1)
1, a kind of feature of Luminous surveyors' staff is: in an one side was the cavity of four prism type chi body of poly (methyl methacrylate) plate, lead accumulator, bulb and switching sequence were electrically connected.
