Description
Technical Field
[0001] The utility model relates to the technical field of set square line drawing tools, in particular to a set of triangular rulers for woodworking. Background Art
[0002] A triangle ruler, also known as a set square, is a commonly used drawing and measuring tool. A triangle ruler has three corners and three sides, and each set of triangle rulers is composed of two special right triangles. One is an isosceles right triangle ruler, and the other is a right triangle ruler with special angles. It is a tool used to draw line segments (especially straight lines) and measure lengths. There are usually scales on the triangle ruler to measure lengths. Some triangle rulers have special shapes such as letters, waves or circular holes in the middle to facilitate users to draw corresponding figures according to actual conditions.
[0003] When drawing lines on inclined and vertical surfaces, it is difficult to fix the carpenter's triangle ruler on the wood tightly, and the carpenter's triangle ruler is easy to slip, resulting in line drawing failure. At the same time, the existing carpenter's triangle ruler is limited in length, and it is impossible to draw longer auxiliary lines for marking as needed. The only way is to use the repeated extension method to extend the vertical lines in sequence. The line drawing process is slow, and when drawing straight lines at various angles, it is necessary to adjust the ruler angle and mark it first, and then draw the straight line of this angle according to the mark. The line drawing is more troublesome, so the overall line drawing process efficiency is greatly reduced. The existing carpenter's ruler on the market can no longer meet the needs of fast line drawing.
[0004] Based on the above situation, the utility model proposes a multifunctional and easy-to-use triangular ruler for woodworking. Summary of the invention
[0005] In order to overcome the shortcomings of the existing carpenter's triangle ruler that it is difficult to fix the lines on the inclined surface, the length is limited and the straight line at any angle cannot be directly drawn, the utility model provides a multifunctional and easy-to-use carpenter's triangle ruler.

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example
[0022] A triangular set of woodworking rulers, such as Figure 1-Figure 3 As shown, it includes a triangle plate 1, a corrugated frame 2, a rectangular frame 3 and a fitting mechanism. The corrugated frame 2 is opened at the lower part of the triangle plate 1, the rectangular frame 3 is opened at the part of the triangle plate 1 close to the hypotenuse, the hypotenuse of the triangle plate 1 is provided with an angle scale, and the triangle plate 1 is provided with a fitting mechanism.
[0023] like Figure 1-Figure 3 As shown, the fitting mechanism includes a rotating plate 4, a reset spring 5 and a connecting ring 6. The right side of the triangular plate 1 is rotatably connected to the rotating plate 4, and the upper and lower parts of the left side of the rotating plate 4 are fixedly connected to the connecting ring 6. A reset spring 5 is fixedly connected between the connecting ring 6 and the triangular plate 1.
[0024] like Figure 1 As shown, the triangle plate 1, the rotating plate 4 and the extension plate 9 are all made of stainless steel metal, which is used to extend the service life of the triangle ruler for woodworking.
[0025] like Figure 1 As shown, the edges of the rotating plate 4, the triangular plate 1, the wave frame 2 and the rectangular frame 3 are all engraved with scales for precise measurement and drawing.
[0026] When a carpenter uses a triangle ruler to draw lines or measure, he can generally draw a straight line of a specific length or measure the length of a line segment through the right-angled side, hypotenuse and surface scale of the set square 1. When a carpenter needs to draw a wavy line, he can also draw it through the wavy frame 2. When a carpenter needs to draw a rough circle, he can use a nail to pass through the round hole 8 on the set square 1 and nail it into the wood to limit the set square 1. Then, place the pen in another round hole 8 or on the edge of the wavy frame 2, the rectangular frame 3 and the round head hole 7, and then use the pen tip to rotate the set square 1 to draw circles of different sizes. Carpenters can also draw parallel lines with fixed spacing through the hypotenuse of the set square 1 and the rectangular frame 3.
[0027] When a carpenter needs to draw lines on an inclined plane or a vertical angle, the rotating plate 4 can be rotated according to the angle of the inclined plane, and the reset spring 5 will be deformed immediately to ensure that the triangle plate 1 and the rotating plate 4 are as close to and against the wood as possible, thereby increasing the friction between the carpenter's triangle ruler and the wood, and preventing the triangle ruler from offsetting and causing drawing failure when the carpenter draws lines. After the rotating plate 4 is separated from the wood, it rotates in the opposite direction and resets under the action of the reset spring 5. When the carpenter needs to draw multiple parallel lines with different spacings, the rotating plate 4 can be rotated 90 degrees and fit against the corner of the edge of the wood. The reset spring 5 will be deformed immediately, and then the pen tip is inserted into different wave grooves of the wave frame 2, and then the triangle plate 1 and the pen tip are slid along the edge of the wood to draw multiple parallel lines with different spacings. Example
[0028] On the basis of Example 1, Figure 4 and Figure 5 As shown, it also includes a circular hole 8, an extension plate 9, a threaded rod 10 and a threaded cap 11. The triangular plate 1, the rotating plate 4 and the extension plate 9 are all provided with a plurality of circular holes 8 for the threaded rod 10 to pass through. The threaded rod 10 can be rotatably connected to the triangular plate 1, the rotating plate 4 and the extension plate 9. The threaded cap 11 is threadedly connected to the rear end of the threaded rod 10. The extension plate 9 can pass through the circular holes 8 of the triangular plate 1 and the extension plate 9 through the threaded rod 10 and be fixed to the triangular plate 1 with the help of the threaded cap 11.
[0029] like Figure 4 As shown, it also includes a round head hole 7. The parts of the triangle plate 1 close to the two right-angled sides are provided with round head holes 7 parallel to the adjacent right-angled sides. The extension plate 9 can pass through the round head hole 7 of the triangle plate 1 and the round hole 8 of the extension plate 9 through the threaded rod 10 and be fixed to the triangle plate 1 with the help of a threaded cap 11. The threaded rod 10 is movably connected with the round head hole 7.
[0030] When the length of the right-angled side and the hypotenuse of the triangle 1 is limited and it is impossible to draw a longer auxiliary line as required, an extension plate 9 can be installed on the right-angled side and the hypotenuse of the triangle 1 and the rotating plate 4 through the threaded rod 10 and the threaded cap 11 to increase the length of the triangle 1 that can draw straight lines. The extension plate 9 can also be disassembled when not in use. When the carpenter wants to draw straight lines of various angles, an extension plate 9 can be installed at the round head hole 7 through the threaded rod 10 and the threaded cap 11. The threaded rod 10 can slide in the round head hole 7, and the extension plate 9 can rotate on the threaded rod 10. Then, in conjunction with the angle scale on the hypotenuse of the triangle 1, straight lines of various angles can be drawn or measured.
[0031] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
