Description

Technical Field

[0001] The utility model belongs to the technical field of the electric power industry, and specifically relates to a drawing mold for wiring analysis of an electric energy meter. Background Art

[0002] When analyzing the wiring of electric energy meters in the power industry, it is necessary to draw phasor diagrams based on the measured voltage, current, and phase angle between voltage and current. During the drawing process, it is necessary to switch between a ruler and a semicircle.

[0003] In the Chinese patent with publication number CN202271728U, a combination ruler for accounting is mentioned, which belongs to the technical field of ruler devices for accounting. Some rulers used in accounting statistics to draw some charts and curves have single functions. Sometimes it is troublesome, time-consuming and laborious to select and select these charts and curves. The rulers cannot be organically coordinated to draw charts and curves, which is inefficient. This problem has always existed and has not been well solved. The technical solution of the utility model is: a dot drawing template, a circle drawing template, a check mark drawing template and an asterisk drawing template are respectively provided on the ruler, and the semicircle instrument and the ruler are hinged together by a rotating shaft. Its advantage is that because the combination of the semicircle instrument and the ruler can conveniently and efficiently produce some more complex accounting professional charts and curves by relative rotation around the rotating shaft, it is simple and convenient to use it, saving time and effort, and greatly improving the work efficiency of accounting professional charts and curves.

[0004] The above-mentioned combined ruler is simple and convenient to operate, saves time and effort, and greatly improves the work efficiency of accounting professionals in drawing charts and curves. However, it is not convenient to carry and operate. The semicircular instrument and the ruler are large in size and cannot be folded and carried around. When the semicircular instrument is in use, it is not convenient to move the semicircular instrument for measurement because its position is fixed on the ruler, which greatly reduces the convenience when drawing.

[0028] A second ruler 3, the second ruler 3 is sleeved on the outside of the rotating shaft 2;

[0029] A circular instrument mechanism 4, which is arranged outside the first straight ruler 1;

[0030] The sliding mechanism 5 is installed on the inner wall of the first ruler 1.

[0031] The roundness instrument mechanism 4 includes a measuring scale plate 401, scale markings 402 and angle markings 403. The measuring scale plate 401 is fixedly connected to the outside of the sliding mechanism 5. The scale markings 402 are provided on the top outer wall of the measuring scale plate 401. The top of the measuring scale plate 401 is provided with angle markings 403. The outside of the angle markings 403 is rotatably connected with an indicator needle 404. The indicator needle 404 is rotatably connected to the outside of the measuring scale plate 401. The scale markings 402 are evenly arranged on the outer ring surface of the measuring scale plate 401.

[0032] Specifically, by rotating the indicator needle 404 at the top of the measuring ruler 401, a quick positioning and marking operation can be performed when drawing an angle, and a convenient combination of a ruler and a semicircular instrument can be performed for drawing.

[0033] As can be seen from the above, when the drawing tool is folded and carried, the operator first rotates the second ruler 3. Through the movable rotation of the second ruler 3 on the rotating shaft 2, the second ruler 3 can be folded and stored inside the first ruler 1. When drawing, through the movable rotation of the indicator needle 404 on the angle mark 403, quick marking can be performed during angle measurement, making the drawing tool more convenient when drawing.

[0034] Embodiment 2:

[0035] refer to Figure 2 and Figure 3 As shown, the sliding mechanism 5 includes a sliding groove 501, a sliding plate 502 and a connecting rod 503. The sliding groove 501 is opened on the inner wall of the first ruler 1. The sliding plate 502 is inserted into the sliding groove 501. The connecting rod 503 is fixedly connected to the outside of one side of the sliding plate 502. The sliding plate 502 is slidably connected inside the sliding groove 501. One side of the connecting rod 503 is fixedly connected to the outside of the measuring ruler plate 401. The second ruler 3 is rotatably connected to the rotating shaft 2. The second ruler 3 is inserted into the inside of the first ruler 1.

[0036] Specifically, by sliding the sliding plate 502 in the sliding groove 501, the sliding plate 502 can be moved inside the first straight ruler 1, so that the measuring ruler 401 is fixedly connected to the sliding plate 502 through the connecting rod 503, and the circular instrument mechanism 4 can be slid to the position.

[0037] As can be seen from the above, when the circular instrument mechanism 4 is performing a drawing operation, the sliding plate 502 can slide and retract inside the sliding groove 501 through the sliding operation of the sliding plate 502 in the sliding groove 501, so that the measuring scale plate 401 can slide outside the first straight ruler 1 through the connection of the connecting rod 503 on the sliding plate 502, so that the position of the measuring scale plate 401 can be moved and adjusted when drawing, which increases the convenience when drawing.
