Abstract
The utility model discloses a straight scale. The straight scale consists of a line weight, a triangular tip, a straight scale plate, a wall line and a triangular notch, and is characterized in that the triangular notch is formed at the upper end of the straight scale plate, and the triangular tip is formed at the lower end of the straight scale plate; a concave angle point of the triangular notch and the peak of the triangular tip are positioned on the straight line of the center of the straight scale plate; the wall line is connected to the concave angle point of the triangular notch; and when the straight scale is used, the upright side surface of the straight scale plate is tightly attached to an object to be measured, the line weight is put down from the triangular notch, and the wall line passes through the peak of the triangular tip to achieve a perpendicular standard. The straight scale has the advantages of simple design, low cost and high practicability, and is convenient to use.
Description
Technical field
The utility model relates to a kind of ruler, relates in particular to a kind of ruler that can the measuring vertical degree, belongs to the dip stick technical field.
Background technology
At present, known technology is when measuring the flatness of metope on engineering; Survey crew can use ruler to measure, and ruler can't be measured the verticality of metope, then needs to carry the survey instrument of the same measuring vertical degree more; Before the utility model is not made; The use of ruler that can not measuring vertical, the patent searching document, it is open not have this technological new solution.
Summary of the invention
But in order to overcome the deficiency of not having the ruler of measuring vertical degree in the prior art; The purpose of the utility model is for but a kind of ruler that has the vertical measuring vertical degree of line is provided; 1.5 meters of ruler length, but the measuring vertical degree erect, laterally can measure flatness; Reach dual-use material, purpose easy to carry.
The utility model solves the technical scheme that its technical matters takes: by line hang down, trigonometric expression tip, ruler plate, wall line, trigonometric expression breach form; The higher authorities that it is characterized in that the ruler plate are the trigonometric expression breach; Following is the trigonometric expression tip; The cusp of the re-entrant angle point of trigonometric expression breach and trigonometric expression tip is on the straight line at ruler plate center, and the wall line is connected the re-entrant angle point of trigonometric expression breach, during use the ruler plate is erect the side near Measuring Object; Put down line from the trigonometric expression breach and hang down, the wall line then is vertical standard through the cusp of trigonometric expression tip.
The beneficial effect of the utility model is a simplicity of design, and is with low cost, easy to use, and practicality is bigger.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
Fig. 1 is the synoptic diagram of the utility model.
1. lines hang down among Fig. 1,2. trigonometric expression tip, 3. ruler plate, 4. wall line, 5. trigonometric expression breach.
Embodiment
The utility model by line hang down 1, trigonometric expression tip 2, ruler plate 3, wall line 4, trigonometric expression breach 5 form; The higher authorities that it is characterized in that ruler plate 3 are trigonometric expression breach 5; Following is a trigonometric expression tip 2; The cusp of the re-entrant angle point of trigonometric expression breach 5 and trigonometric expression tip 2 is on the straight line at ruler plate 3 centers, and wall line 4 is connected the re-entrant angle point of trigonometric expression breach 5, during use with ruler plate 3 setting sides near Measuring Object; Put down line from trigonometric expression breach 5 and hang down 1, wall line 4 then is vertical standard through the cusp of trigonometric expression tip 2.
