Abstract
The utility model relates to a multifunctional ruler, wherein the top margin of the long side of a strip-shaped flat ruler is manufactured into a hollow pipe, the hollow pipe is made of transparent materials, rolling balls are installed inside, length scales are marked with the middle point of the long side of the outer wall of the hollow pipe as a round dot to two sides with equal distance, and an indicating needle is fixedly installed on the middle point. Users can directly utilize the strip-shaped flat ruler to protract beelines or protract beeline length in normal use, when the ruler is used to detect whether a plane is horizontal or not, users can paste the hollow pipe on the flat ruler with the plane, if the plane is horizontal, the rolling ball in the hollow pipe does not roll, if the plane has angles, the rolling ball in the hollow pipe may roll, and the inclined direction of the plane can be judged according to the rolling direction. The multifunctional ruler has the advantages of exquisite appearance, convenient operation, unique functions, convenience, practicability, and the like.
Description
Technical field
The utility model relates to a kind of survey tool, especially a kind of multifunctional ruler.
Background technology
As everyone knows, ruler is a survey tool the most frequently used in people's study and work.But present ruler function is fairly simple, can only measure length or draw straight line, whether in case need measurement plane when level or monitor station face tilt direction, ruler just can't be offered help, people also need use other instrument to detect, and bring very big inconvenience to people.For this reason, we provide a kind of multi-functional ruler that can address the above problem very necessary.
Summary of the invention
The purpose of this utility model provides a kind of multifunctional ruler, be used to solve common ruler can't measurement plane the problem of level whether.
For achieving the above object, the utility model multifunctional ruler comprises the bar shaped ruler, and the long limit top margin of bar shaped ruler is processed into hollow pipe, and hollow pipe is that transparent material is made, the inside ball of packing into; With the long limit of hollow pipe outer wall midpoint is that round dot is to both sides equidistant marking length scale, and at midpoint fixed installation pointer.
After adopting said structure, when normally using, the user can directly utilize the bar shaped ruler to draw straight line or measure straight length; During level, the user can be close to the plane to the hollow pipe on the ruler to detection plane, if planar horizontal, then the ball in the hollow pipe does not roll, if there is angle on the plane,, and judge the incline direction on plane according to the rolling aspect just then the interior ball of hollow pipe can roll.
Compared with the prior art, the beneficial effects of the utility model are: the profile fineness, easy and simple to handle, function is peculiar, convenient and practical, can measure the length levelness on energy measurement plane again, the measuring condition that facilitates.
Description of drawings
Fig. 1 is the overall structure schematic diagram of the utility model multifunctional ruler.
Number in the figure: 1 is that ruler, 2 is that hollow pipe, 3 is that ball, 4 is that length scale, 5 is pointer.
The specific embodiment
As shown in Figure 1, the utility model multifunctional ruler comprises bar shaped ruler 1, and the long limit top margin of bar shaped ruler 1 is processed into hollow pipe 2, and hollow pipe 2 makes for transparent material, the inside ball 3 of packing into; With the long limit of hollow pipe 2 outer walls midpoint is that round dot is to both sides equidistant marking length scale 4, and at midpoint fixed installation pointer 5.
Claims (1)
1, a kind of multifunctional ruler comprises bar shaped ruler (1), it is characterized in that: the long limit top margin of bar shaped ruler (1) is processed into hollow pipe (2), and hollow pipe (2) makes for transparent material, the inside ball (3) of packing into; With the long limit of hollow pipe (2) outer wall midpoint is that round dot is to both sides equidistant marking length scales (4), and at midpoint fixed installation pointer (5).
