[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of them. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0019] Figure 1 It is a schematic structural diagram of a chart correction device provided by an embodiment of the present invention. As Figure 1 shown, it includes: a chart correction ruler 1, a positioning slider 3, and a correction stamp 4; among them, the chart correction ruler 1 has a triangular plate structure.

[0020] Specifically, as Figure 1 shown, a slide groove 2 is opened in the middle of the chart correction ruler 1, the positioning slider 3 is arranged in the slide groove 2, and the positioning slider 3 can slide along the slide groove 2.

[0021] Figure 2 It is a three-dimensional view of a positioning slider provided by an embodiment of the present invention. As Figure 2 shown, a hollow positioning groove 7 is opened in the middle of the positioning slider 3, and the correction stamp 4 is arranged in the positioning groove 7.

[0022] Preferably, as Figure 2 shown, the positioning slider 3 is a rectangular slider, the positioning groove 7 is a rectangular slot, and the shape of the positioning groove 7 matches the shape of the correction seal 4.

[0023] Preferably, as Figure 2 shown, positioning scale lines 5 are further provided on each side of the positioning slider 3. Specifically, the positioning scale lines 5 include horizontal scale lines and vertical scale lines, and the extension lines of the horizontal scale lines and the vertical scale lines intersect at the center position of the positioning groove 7.

[0024] In the embodiment of the present utility model, horizontal and vertical scale lines are engraved on the surface of the positioning slider 3 to indicate the position of the hollow center. As Figure 2 shown, the downward protruding part of the positioning slider 3 can just be stuck at the sliding groove 2, so that the positioning slider 3 can slide up and down along the sliding groove 2. The hollow part of the positioning slider 3 is consistent with the protruding part of the correction seal 4, ensuring that the correction seal 4 can contact the paper surface and the position remains fixed.

[0025] In the embodiment of the present utility model, the correction seal 4 is used to print the chart illustration on the target position of the chart to be corrected.

[0026] Figure 3 is a three-dimensional view of a correction seal provided according to an embodiment of the present utility model. As Figure 3 shown, the correction seal 4 includes at least one cube, and chart illustrations 6 are engraved on each face of the cube.

[0027] Preferably, as Figure 1 shown, the hypotenuse of the chart correction ruler 1 is a wavy line structure, and this structure can be used to draw chart illustrations such as submarine cables.

[0028] Preferably, as Figure 1 shown, the opening direction of the sliding groove 2 is parallel to the direction of one right-angled side of the chart correction ruler 1.

[0029] Figure 4 is an application schematic diagram of a chart correction device provided according to an embodiment of the present utility model. As Figure 4 shown, by closely attaching a triangular plate or a parallel ruler to the bottom right-angled side of the chart correction ruler 1, the chart correction ruler 1 can be horizontally moved along the latitude direction on the chart. At the same time, in cooperation with the vertical movement of the positioning slider 3, combined with the vertical and horizontal scale lines on the positioning slider, the hollow center of the positioning slider 3 can be quickly moved to the given longitude and latitude.

[0030] During use, first, through the horizontal movement of the chart correction ruler 1 and the vertical movement of the positioning slider 3, the positioning slider 3 is moved to the specified longitude and latitude. Then, select the correction seal 4 with the corresponding chart illustration and print it on the chart to be corrected through the positioning groove 7 at the hollow part of the positioning slider 3 to complete the modification.

[0031] As can be seen from the above description, the embodiment of the present utility model provides a chart correction device. Compared with the prior art, it has the following technical effects: This device can not only quickly determine the correction position, but also quickly and standardly print the chart illustration on the chart by using the correction seal, overcoming the technical problems of low efficiency and non-standard charting in the small corrections of the existing hand-drawn charts.
