[0002] A ruler, also known as a measuring ruler or a scale ruler, is a tool used to draw line segments and measure length. There are usually scales on the ruler to measure length. Some rulers have special shaped holes such as letters or circles in the middle to facilitate users to draw. They are usually used to measure and calculate length. They are generally divided into tape measures, vernier calipers, squares, and rulers.

[0003] For example, the patent document with the announcement number CN220018381U discloses a drawing measuring ruler, which relates to the field of engineering cost measurement technology, including a ruler body, a plurality of evenly distributed scale lines are opened on the side of the top of the ruler body, and a flattening mechanism is provided at the bottom of the ruler body; the flattening mechanism includes a setting opening opened at one end of the ruler body, and two setting ears are fixedly provided on both sides of the inner wall of the setting opening, wherein two setting ears in opposite positions are rotatably connected with a second setting column, and the inner wall of the bidirectional threaded hole opened at one end of the second setting column is threadedly connected with two screws, one end of the screw is fixedly connected with a fixed block, the inner wall of the slide groove opened on one side of the fixed block is rotatably connected with a stud, and the outer wall of the stud is threadedly connected with a slide plate, and after the transmission block is separated from the setting shaft, the transmission block is connected with the stud, and the knob is turned to drive the stud, and the stud rotates to drive the slide plate to drive the connecting block to move, thereby raising the flattening roller, so that the ruler body contacts the drawing for measurement, which is convenient for the use of the measuring ruler.

[0004] However, in actual use, this structure can only extend the internally adjustable drawing ruler, resulting in low ruler adjustment efficiency. It is impossible to quickly extend and adjust the ruler as needed during actual use. At the same time, the equipment cannot properly fix and limit the drawing ruler before and after adjustment, and cannot ensure the overall firmness of the drawing ruler. It cannot meet daily use needs. Therefore, it is urgent to design a drawing ruler to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to provide a drawing measuring ruler to solve the problem that the existing structure proposed in the above background technology can only perform the internal adjustment type drawing measuring ruler extension operation during actual use, resulting in low ruler adjustment efficiency and inability to perform rapid extension adjustment operations as needed during actual use. At the same time, the equipment cannot properly fix and limit the drawing measuring ruler before and after adjustment, cannot ensure the overall firmness of the drawing measuring ruler, and cannot meet daily use needs.

[0006] To achieve the above object, the utility model provides the following technical solution: a drawing measuring ruler, comprising a first ruler plate, one end of which is provided with a movable shaft, one end of which is movably connected to a second ruler plate through the movable shaft, and one side of the surface of the first ruler plate and the movable shaft are both provided with measuring scales;

[0007] A docking seat, one end of the second scale plate is fixedly connected to the docking seat, a docking frame is fixedly connected to the surface of the docking seat, and a docking block is movably connected inside the docking frame.

[0008] Preferably, a plug-in slot is provided inside the docking seat, and a lanyard buckle is fixedly connected between the docking seat and one end of the docking frame.

[0009] Preferably, a socket is fixedly connected to the bottom end of the docking block, and damping rubber strips are arranged at four corners of the inner wall of the socket.

[0010] Preferably, fitting rubber pads are provided at the inner centers of the first scale plate and the second scale plate, and magnetic suction rings are provided at the inner edges of the first scale plate and the second scale plate.

[0011] Preferably, a rotation groove is provided at the center of one end of the first scale plate and the movable shaft, and a butt rubber strip is provided on the upper and lower sides of one end of the first scale plate and the movable shaft.

[0012] Preferably, one side of the first scale plate and the movable shaft are both fixedly connected with a scale bevel strip, and the sides of the two groups of scale bevel strips close to each other are both provided with a fitting adhesive strip.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] The drawing measuring ruler can quickly extend and adjust the first and second scale plates by means of the first scale plate, movable axis, second scale plate, measuring scale, fitting rubber pad, magnetic ring, rotating groove, docking rubber strip, ruler bevel strip and fitting rubber strip. In actual use, the staff can perform normal measurement of the drawing through the measuring scale on the surface of the first scale plate. When the measuring length is not enough, the second scale plate can be directly rotated along the movable axis inside the rotating groove at one end of the first scale plate, and the second scale plate can be rotated from the bottom of the first scale plate to one end of the first scale plate. Then, the first scale plate and the second scale plate can be used to perform a longer measurement operation that meets the requirements of the drawing. At the same time, when the first scale plate and the second scale plate are folded and adjusted daily, the magnetic ring at the edge between the first scale plate and the second scale plate can perform a stable adsorption docking operation to ensure stable docking. At the same time, the fitting rubber pad between the first scale plate and the second scale plate and the fitting rubber strip inside the ruler bevel strip on one side can be adaptively fitted and protected with the drawing surface to perform more stable drawing measurement work, which reflects the practicality of the equipment design.

[0015] The drawing measuring ruler further improves the overall use effect of the equipment by providing the first scale plate, the second scale plate, the docking frame, the docking block, the plug-in slot, the lanyard buckle, the plug-in seat and the damping rubber strip. In daily use, when the first scale plate and the second scale plate are docked, the docking block at one end of the first scale plate can be stably docked to the inside of the docking frame on the surface of the docking seat at one end of the second scale plate, and the plug-in seat and the damping rubber strip at the bottom end of the docking block can be stably clamped in the plug-in slot inside the docking seat, so that the first scale plate and the second scale plate at one end can be more firmly limited and fixed, making the first scale plate and the second scale plate more stable after being folded. At the same time, the first scale plate and the second scale plate can be hung and carried for use as a whole through the docking seat and the lanyard buckle at one end of the docking frame, which reflects the comprehensiveness of the equipment design.
