Description

Technical Field

[0001] The utility model belongs to the technical field of engineering cost, and more specifically, particularly relates to a measuring ruler for engineering. Background Art

[0002] A measuring ruler, also known as a measuring ruler or a graduated ruler, is a tool used to draw line segments and measure lengths. The ruler usually has scales to measure lengths. Some rulers have special shapes such as letters or circular holes in the middle to facilitate users to draw. They are usually used to measure and calculate lengths. They are generally divided into tape measures, vernier calipers, squares, etc. Rulers are usually made of plastic, iron, stainless steel, plexiglass, etc. The object of measurement, that is, the object of measurement, mainly refers to geometric quantities, including length, area, shape, elevation, angle, surface roughness, and form and position errors.

[0003] Based on the above, the inventors have discovered the following problems: in the field of engineering cost, personnel are required to carry a measuring ruler to the construction site for on-site measurement. When measuring a trough, its angle and width need to be measured. A general measuring ruler can only measure one of the items separately. Therefore, it is necessary to prepare a variety of different measuring rulers for measurement, which is inconvenient and not conducive to improving the overall measurement efficiency.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and an engineering measuring ruler is provided to achieve a more practical purpose. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides an engineering measuring ruler to solve the problem that the existing measuring ruler can only measure one dimension separately.

[0006] The purpose and effect of the engineering measuring ruler of the utility model are achieved by the following specific technical means:

[0007] A measuring ruler for engineering purposes comprises a transverse rod, a limiting bolt is installed on the transverse rod, an angle measuring ruler is connected to the transverse rod via the limiting bolt, a moving groove is opened on the side of the transverse rod, a moving part is installed inside the moving groove, a fixing nut is installed at one end of the moving part, the moving part is connected to the fixing bolt via the fixing nut, one end of the fixing bolt abuts against the inner wall of the moving groove, one end of the moving part is connected to a positioning plate via the fixing part, and a pointer is installed on the positioning plate.

[0008] Furthermore, the number of the moving parts and the positioning plates is two, the transverse rod is provided with a distance scale, and the pointer corresponds to the distance scale.

[0009] Furthermore, a central axis is installed at the middle position of the lower part of the angle measuring ruler, and the angle measuring ruler is movably connected to a vertical rod through the central axis, and the vertical rod and the horizontal rod are kept perpendicular to each other.

[0010] Furthermore, an arc-shaped groove is provided on the angle measuring ruler, a limiting pointing member is installed on the upper part of the vertical rod, a pointing groove is provided on the side of the limiting pointing member, and the limiting pointing member is located in the middle of the arc-shaped groove.

[0011] Furthermore, a transverse groove is formed on the transverse rod, and the limiting bolt is connected to the inside of the transverse groove.

[0012] Furthermore, cushion blocks are installed at both ends of the lower part of the transverse rod, and anti-slip grooves are provided on the lower surfaces of the cushion blocks.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] The utility model pushes the angle measuring ruler. When the angle measuring ruler moves, the limit bolt connected thereto moves inside the transverse groove, so that the angle measuring ruler can be made to move linearly. The angle measuring ruler drives the vertical rod to move. The vertical rod gradually contacts the inner wall of the groove. The inner wall pushes the vertical rod to tilt. The vertical rod moves around the central axis. The upper limiting pointing member moves inside the arc groove. The inclination angle of the inner wall of the groove can be read according to the angle scale corresponding to the pointing groove on the limiting pointing member. The angle can be measured. The moving member is fixed by the fixing bolt. At this time, the distance between the distance scales pointed by the two pointers is the width of the groove, so that the purpose of measuring multiple sizes can be achieved.

A distance scale 11 is set on the transverse rod 1. The pointer 17 corresponds to the distance scale 11. The fixing bolt 14 is rotated to separate one end of the fixing bolt 14 from the inner wall of the moving groove 10. At this time, the moving part 12 is pushed to make the positioning plate 16 at one end of the moving part 12 fit to one side of the inner wall of the groove, and the positioning plate 16 on the other moving part 12 fits to the inner wall on the other side. After the positioning plate 16 is moved, the moving part 12 is fixed by the fixing bolt 14.

[0027] Among them, a central axis 6 is installed at the middle position of the lower part of the angle measuring ruler 3, and the angle measuring ruler 3 is movably connected to a vertical rod 7 through the central axis 6.

[0030] In the utility model, firstly, the transverse rod 1 is placed horizontally on the upper part of the slot, and the transverse rod 1 is supported by the pad 18 at the lower part. When the angle inside the slot needs to be measured, the angle measuring ruler 3 is pushed. When the angle measuring ruler 3 moves, the limit bolt 2 connected thereto moves inside the transverse slot 9, so that the angle measuring ruler 3 can move linearly. The angle measuring ruler 3 drives the vertical rod 7 to move, and the vertical rod 7 gradually contacts the inner wall of the slot. If the angle between the inner wall and the bottom surface of the slot is greater than 90 degrees, the inner wall will push the vertical rod 7 to tilt, and the vertical rod 7 moves around the central axis 6. The upper limiting pointing member 8 moves inside the arc slot 5, and the angle scale 4 corresponding to the pointing slot on the limiting pointing member 8 is adjusted. The inclination angle of the inner wall of the groove can be read. If the angle between the inner wall and the bottom surface of the groove is less than 90 degrees, the upper limiting pointing member 8 is moved to make the lower part of the vertical rod 7 fit the inner wall of the groove, and the angle can be measured. When the width of the groove needs to be measured, the fixing bolt 14 is rotated to separate one end of the fixing bolt 14 from the inner wall of the movable groove 10. At this time, the movable member 12 is pushed to make the positioning plate 16 at one end of the movable member 12 fit to one side of the inner wall of the groove. Similarly, the positioning plate 16 on the other movable member 12 fits to the inner wall on the other side. After the positioning plate 16 is moved, the movable member 12 is fixed by the fixing bolt 14.
