Description

Combined angle marking ruler

Technical Field

The utility model relates to a hand tool's technical field, a modular angle marking off chi specifically says so.

Background

In the work of carpentry and door and window decoration, the square timber of the section bar is often required to be butted into a 90-degree right angle, and in order to accurately butt the transverse frame and the longitudinal frame, the end parts of the transverse frame and the longitudinal frame are required to be cut into 45-degree oblique angles. The existing method is to use a semicircle gauge to mark points on a square wood, then use a ruler to connect the two points for drawing, and finally cut along the drawn points. The line drawing efficiency is not high and the error is large. In order to improve the efficiency of drawing a line, someone cuts into 45 degrees oblique angles with the one end of L shape angle iron or aluminum alloy ex-trusions and regards as angle drawing rule, leans on the edge of waiting to cut the section bar with the side of angle drawing rule during the use, puts the one side at 45 degrees oblique angles on the drawing line face of waiting to cut the section bar, draws a line along 45 degrees oblique angles. Therefore, the line drawing efficiency can be greatly improved, and the line drawing is accurate and has small error. However, the fixed line drawing ruler only has one angle, the length of the oblique edge is also fixed, in actual work, oblique lines of 30 degrees or 60 degrees are often required to be drawn besides the angle of 45 degrees, and the length of the line drawing is also changed in a plurality of ways according to the size of the section to be cut. In addition, the fixed knot that appears is bulky, and inconvenient accomodating, the setting-out chi of multiple specification and dimension need occupy very big storage space.

Detailed Description

As shown in figure 1, combination formula angle marking off chi includes locating plate 1 and setting-out board 2, and locating plate 1 and setting-out board 2 are the platelike structure that can split, link together locating plate 1 and setting-out board 2 perpendicularly again during the use.

As shown in fig. 2, at least two mounting holes 4 are arranged in a straight line on the positioning plate 1, and the axes of the mounting holes 4 are perpendicular to the positioning plate 1, so that the line drawing plate 2 can be vertically inserted into the mounting holes 4. In the use, the locating plate 1 is used for being attached to the edge of a square wood to be cut, so that the locating function is achieved, and the edge of the line drawing plate 2 is parallel to the edge of the square wood to be cut.

As shown in fig. 3 and 4, a plunger 3 matched with the mounting hole is arranged on one side edge of the line drawing plate 2, the plunger 3 is of a cylindrical structure connected with the line drawing plate 2 into a whole, the axis of the plunger 3 is parallel to the line drawing plate 2, the line drawing plate 2 is of a quadrilateral plate-shaped structure, and at least two sides of the other three sides of the line drawing plate 2 except the reference side 8 with the plunger 3 are intersected to form an acute angle of 45 degrees, 60 degrees or 30 degrees. In the embodiment of fig. 3, in addition to the reference side edge 8 with the plunger 3, one of the other three side edges is an outer side edge 9 parallel to the reference side edge 8, and two side edges at two ends of the outer side edge 9 intersect at 45 degrees and 90 degrees respectively. In the embodiment of fig. 4, in addition to the reference side 8 with the plunger 3, one of the other three sides is an outer side 9 parallel to the reference side 8, and the two sides at the two ends of the outer side 9 intersect at 30 degrees and 60 degrees, respectively. The two line drawing plates can meet the most common line drawing requirements of 30 degrees, 45 degrees, 60 degrees and 90 degrees. Of course, in order to meet the requirement of more angles or the requirement of more line lengths, the drawing plates with more specifications can be arranged, as long as the plungers 3 on the reference side edges 8 of all the drawing plates can be matched with the mounting holes 4 on the positioning plate 1.

As shown in fig. 1, as a further improvement of the present invention, one side of the positioning plate 1 has a boss 5 surrounding the mounting hole 4, and the mounting hole 4 penetrates through the center of the boss 5. Boss 5 protrusion in locating plate 1's surface, with locating plate 1 fusion as an organic whole, increased the thickness around mounting hole 4, also prolonged the length of mounting hole 4 simultaneously, can effectively improve the firm degree that plunger 3 and mounting hole 4 combine under the prerequisite that does not increase locating plate 1 thickness, avoid pulling out many times and insert and cause mounting hole 4 wearing and tearing, increase of service life.

In addition, a rectangular window 6 is arranged on the positioning plate 1, a special-shaped window 7 is arranged on the line drawing plate 2, and the special-shaped window 7 is in a right-angled trapezoid shape. The arrangement of the rectangular window 6 and the special-shaped window 7 can effectively reduce the material cost in production, meanwhile, a handle for holding can be provided for handheld operation, and the angle in each window can also provide a line drawing ruler with various internal angles.

The sectional shapes of the mounting hole 4 and the plunger 3 may be square or circular. As shown in fig. 1, the mounting hole 4 is a columnar through-hole having a rectangular cross section, and the plunger 3 is a rectangular columnar body having a cross section matching the mounting hole 4. In addition, a circular structure can be adopted, the mounting hole 4 is a cylindrical through hole with a circular section, and the plunger 3 is a cylinder with a section matched with the mounting hole 4.

As shown in figure 1, when the line drawing plate is used, the positioning plate 1 is taken out, a proper line drawing plate 2 is selected, the positioning plate 1 is vertically placed, the line drawing plate 2 is horizontally placed, the plunger 3 of the line drawing plate 2 is inserted into the mounting hole 4 of the positioning plate 1, the reference side edge 8 of the line drawing plate 2 is tightly attached to the positioning plate after being tightly inserted, and the line drawing plate 2 and the positioning plate 1 form an included angle of 90 degrees. When a line is drawn, the square wood to be cut is placed in a 90-degree included angle formed by the line drawing plate 2 and the positioning plate 1, the line drawing plate 2 is placed on the upper surface of the square wood to be cut, the positioning plate 1 is tightly attached to the side surface of the square wood, the reference side edge 8 on the line drawing plate 2 is parallel to the side edge of the square wood at the moment, the reference side edge 8 and the side edge of the square wood can be used as a reference for drawing the line, and the side edge acute angle on the line drawing plate 2 can be used as a ruler for drawing the line. For example, when the line drawing board 2 shown in fig. 3 is used, a common 45-degree oblique line may be drawn on the upper surface of the square wood; by replacing the line drawing board shown in fig. 4, a 30-degree or 60-degree oblique line can be drawn on the upper surface of the square wood.
