Embodiment 1

[0026] Such as Figure 1 to Figure 3As shown, a combination ruler includes a level ruler 1 and a verticality measurement component, and the verticality measurement component is accommodated on the level ruler 1 . The level ruler 1 is provided with three blister windows 5, which are located at the two ends and the middle side of the level ruler 1 respectively. The verticality measurement assembly includes a square 2, a plumb weight 3 and a plumb hanger 4, the square 2 is detachably connected to the level 1, and the level 1 is provided with a plumb assembly cavity 17, the plumb 3 and the plumb The hammer hanger 4 is placed in the cavity 17 of the plumb component. The side of the level 1 is provided with a square groove 6, the square groove 6 runs through the two sides of the level 1, the square 2 is embedded in the square groove 6, and the upper groove wall of the square groove 6 is provided with two through holes , The square 2 is also provided with two through holes, and the...

Embodiment 2

[0029] Such as Figure 4 to Figure 6 As shown, the combination ruler also includes a levelness measurement assembly, which includes a suspension block pole 11, a light emitter suspension block 12 and a light spot scale disc 13, and the suspension block pole 11 is hinged on the top of the level ruler 1 and the suspension block The turning angle range of the support rod 11 relative to the bottom surface of the level ruler 1 is 0-90°. The other end of the rod storage groove 14 is provided with a hanging block cavity, which is used to accommodate the light emitter hanging block 12. The light spot ruler disk 13 is located at the top of the level ruler 1 and is located on the same straight line as the pole storage groove 14. The light spot ruler disk 13, The support rod storage slot 14 is located on both sides of the root of the hanging block support rod 11, and the light spot scale disc 13 is marked with a scale. The free end of the hanging block pole 11 is provided with a cantile...

Embodiment 3

[0032] When measuring the verticality of the facade, the square 2 is placed on the bottom of the measured facade, and the square 2 is in close contact with the ground or the supporting surface of the facade and the measured facade at the same time, instead of using the level 1 as a base. All the other are with embodiment 1.

Abstract

The invention discloses a combined ruler which comprises a horizontal ruler and a perpendicularity measuring assembly, and the perpendicularity measuring assembly is contained on the horizontal ruler. According to the invention, the perpendicularity measuring assembly is arranged on the horizontal ruler, so that during use, the levelness and the verticality can be qualitatively detected by using the basic functions of the horizontal ruler, the quantized data of the verticality of a measured vertical surface can be obtained through the cooperative use of the perpendicularity measuring assembly and the horizontal ruler, the deviation degree between the measured vertical surface and a vertical reference surface can be compared more visually and more accurately by operators, and the construction and installation quality can be judged more objectively.

Description

technical field [0001] The present invention relates to a measuring tool, more specifically, it relates to a combination ruler. Background technique [0002] The spirit level is a measuring instrument that uses the principle of liquid level to directly display the angular displacement with water bubbles, and measures the relative horizontal position, vertical position, and inclined position deviation of the measured surface. However, ordinary levels can only qualitatively analyze the inclination of the measured surface through the position of the bubble in the bubble window, and it is difficult to obtain more accurate quantitative data on the degree of deviation of the measured surface from the horizontal or vertical plane. Although there are more professional measuring instruments that can measure precise levelness or verticality parameters, these instruments are often bulky, heavy, cumbersome to operate, poor in portability and expensive, and are not convenient for constru...
