Abstract
Description
A multi-functional line drawing tool Technical Field
[0001] This utility model relates to the field of auxiliary drawing tools, specifically a multifunctional drawing tool. Background Technology
[0002] During the production and processing of pipes and plates, some parts need to be cut and bent. In this case, a marking tool is used to mark the cut parts to ensure accuracy.
[0003] However, the existing technology has the following drawbacks:
[0004] However, most existing line drawing tools are single rulers, which can only draw a single marking line at a time. If the cut part is a polygon or contains arcs, multiple tools need to be used to draw it in sequence. Changing tools and re-comparing measurements will waste time. Summary of the Invention
[0005] The purpose of this invention is to provide a multifunctional line drawing tool to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a multifunctional marking tool, comprising a triangular plate, a rotating plate, a fixed plate, and a connecting shaft. A second mounting hole is provided in the middle of the longer side of the triangular plate. A convex strip is fixedly mounted in the middle of one end of the rotating plate. A first mounting hole is provided in the middle of the rotating plate near the convex strip. A third mounting hole is provided at one end of the fixed plate. One end of the connecting shaft passes sequentially through the third mounting hole, the second mounting hole, and the first mounting hole, and is threaded with a fastening nut. The connecting shaft is fixedly connected to the fixed plate and the triangular plate. The rotating plate is rotatably connected to the connecting shaft. A plurality of first circular through holes are evenly provided on the rotating plate.
[0007] Using the above technical solution, the drawing pen passes through the first circular through hole of appropriate length, and as the rotating plate rotates, it can draw an arc shape. The three sides of the triangle and the fixed plate can all assist in drawing straight lines.
[0008] The triangle is an isosceles triangle. The two sides of the triangle near the rotating plate are engraved with first scale lines. The longer side of the triangle is symmetrically engraved with second scale lines along the first mounting hole. An angle scale line is engraved in the middle of the triangle near the rotating plate. The angle scale line is semi-circular and its two sides are symmetrically arranged along the first mounting hole.
[0009] Using the above technical solution, angle markings are engraved on the angle scale lines, which, in conjunction with the rotating plate, can draw oblique lines at different angles.
[0010] The fixing plate is vertically arranged, and a number of second grooves are evenly provided on the side of the fixing plate near the rotating plate. A number of second scale marks are evenly engraved on the side of the fixing plate near the rotating plate. The second scale marks are located between two adjacent second grooves.
[0011] The above technical solution features a vertically mounted fixing plate that is fixedly connected to the bottom of the triangular plate. The fixing plate abuts against the side of the material, thus fixing the marking tool.
[0012] The convex plate has a rectangular cross-sectional shape, the length of the convex plate is the same as the radius of the angle scale line, the width of the convex plate is the same as the separation width of the angle scale line, and both ends of the rotating plate are semi-circular.
[0013] In this technical solution, the side of the convex plate away from the rotating plate is in contact with the inner side of the angle scale line, which facilitates the reading of the angle scale line.
[0014] The rotating plate has several first grooves evenly distributed on the side away from the fixed plate. The length of the first groove is equal to half the width of the rotating plate, and one end of the first groove is connected to the first through hole. The rotating plate has several first scale marks evenly engraved on the side away from the fixed plate. The first scale marks are located between two adjacent first grooves.
[0015] Using the above technical solution, the marking pen extends the marking line along the first groove to ensure accurate marking position, and the first scale mark facilitates reading.
[0016] The triangular plate, rotating plate, and fixed plate are all made of stainless steel, and the corners of the triangular plate, rotating plate, and fixed plate are all rounded and chamfered.
[0017] The above technical solution features rounded corners on all edges of the marking tool to prevent injury to workers' hands.
[0018] Assuming there is a second through hole in the middle of the side of the triangular plate away from the second mounting hole, the thickness of the triangular plate is the same as the thickness of the rotating plate.
[0019] The above technical solution allows for easy hanging and storage of the marking tool through the second circular hole on the triangular plate.
[0020] Compared with the prior art, the beneficial effects of this utility model are:
[0021] The fixing plate of this utility model is tightly abutted against one side of the material. By extending the scribing line along the second groove, a straight line can be drawn. By inserting the scribing pen into the first through hole at the appropriate position, an arc line can be drawn as the rotating plate rotates. By rotating the rotating plate so that the convex plate points to the appropriate position of the angle scale line, and then scribing along one side of the rotating plate, a diagonal line can be drawn.
