AI Technical Summary
When learning maps and orientations, it is difficult for students to accurately judge the relative orientations in the map, especially when the pointing marks in the map are set in an inclined setting.
A directional ruler is designed, including a fixed ruler and a movable ruler. The movable ruler can rotate about the axis and rotate clockwise to perpendicular to the fixed ruler under the action of the limit column, which is convenient for judging the map orientation.
This orientation ruler can not only be used as a ruler, but also as an orientation pointer, helping students accurately judge the relative orientation in the map, increasing their interest in learning and ability to understand the map.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of teaching aids, in particular to an azimuth pointing ruler. Background Art
[0002] Teaching aids can enable students to intuitively and vividly understand teaching content, improve students' learning interest, enrich perceptual knowledge, help form clear concepts, and develop students' observation and thinking abilities.
[0003] Geography, as one of the basic subjects in junior high school, requires the judgment of the azimuth of locations on a map in some courses such as learning maps and azimuths. Generally, the rule of "north is up, south is down, east is left, and west is right" is adopted. However, the direction indicators in some maps are set obliquely, and some students cannot accurately judge the relative azimuth on the map. For this reason, the utility model proposes an azimuth pointing ruler, which can be used as an ordinary ruler and also as an azimuth indicator to facilitate the judgment of map azimuth. Content of the Utility Model
[0004] In view of the above deficiencies in the prior art, the utility model provides an azimuth pointing ruler with a practical structure and convenient for popularization.
[0005] An azimuth pointing ruler includes a fixed ruler and a movable ruler;
[0006] Azimuth marks one are respectively arranged at both ends of the fixed ruler, azimuth marks two are arranged at both ends of the movable ruler, the middle of the fixed ruler and the movable ruler is connected by a rotating shaft, and the movable ruler can rotate around the rotating shaft;
[0007] A limiting column is fixed on one side of the fixed ruler, so that when the movable ruler rotates clockwise to the maximum angle, it is perpendicular to the fixed ruler.
[0008] Preferably, scales are arranged on both the fixed ruler and the movable ruler.
[0009] Preferably, the azimuth mark one is E, W or east, west; the azimuth mark two is N, S or south, north.
[0010] Preferably, when the movable ruler rotates to be perpendicular to the fixed ruler, the azimuth mark one and the azimuth mark two conform to the azimuth of "north is up, south is down, west is left, and east is right".
[0011] Preferably, the movable ruler can rotate to completely coincide with the fixed ruler.
[0012] The beneficial effects of the utility model are as follows:
[0013] The azimuth pointing ruler of the present utility model adopts the combination of a fixed ruler and a movable ruler, and the movable ruler can rotate around the fixed ruler; when used as a straight ruler, the movable ruler rotates to completely coincide with the fixed ruler; when used as a direction indicator, the movable ruler rotates to be perpendicular to the fixed ruler. It is convenient for students to understand maps and azimuths, and increases their learning interest. Description of the Drawings
[0014] In order to more clearly illustrate the technical solutions of the embodiments of the present utility model, the following will briefly introduce the drawings required for use in the embodiments. It should be understood that the following drawings only show some embodiments of the present utility model, and therefore should not be regarded as limiting the scope. For those of ordinary skill in the art, without creative efforts, other related drawings can also be obtained based on these drawings.

[0018] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. Usually, the components of the embodiments of the present utility model described and shown in the drawings here can be arranged and designed in various different configurations.
[0019] In the description of the embodiments of the present utility model, it should be noted that if terms such as "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. indicate the azimuth or position relationship based on the azimuth or position relationship shown in the drawings, or the azimuth or position relationship in which the product of the present utility model is usually placed during use, it is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific azimuth, be constructed and operated in a specific azimuth, and therefore cannot be understood as a limitation of the present utility model. In addition, terms such as "first", "second", "third", etc. are only used for distinguishing descriptions and cannot be understood as indicating or implying relative importance.
[0020] In addition, the appearance of terms such as "horizontal", "vertical", "hanging" does not mean that the components are required to be absolutely horizontal or hanging, but can be slightly inclined. For example, "horizontal" only means that its direction is more horizontal relative to "vertical", and does not mean that the structure must be completely horizontal, but can be slightly inclined.
[0021] As shown in the attached drawings, a direction pointer includes a fixed ruler 1 and a movable ruler 2;
[0022] At both ends of the fixed ruler 1, there are respectively provided with first direction markers 3, and the first direction markers 3 are E, W or east, west; at both ends of the movable ruler 2, there are provided with second direction markers 4, and the second direction markers 4 are N, S or south, north.
[0023] The middle of the fixed ruler 1 and the movable ruler 2 is connected by a rotating shaft 5, and the movable ruler 2 can rotate around the rotating shaft 5; on one side of the fixed ruler 1, a limiting column 6 is fixed, so that when the movable ruler 2 rotates clockwise to the maximum angle, it is perpendicular to the fixed ruler 1. When the movable ruler 2 rotates to be perpendicular to the fixed ruler 1, the first direction marker 3 and the second direction marker 4 conform to the direction of "north on top, south on bottom, west on the left, and east on the right".
[0024] Both the fixed ruler 1 and the movable ruler 2 are provided with scales. When the movable ruler 2 rotates to completely coincide with the fixed ruler 1, it can be used as a straight ruler.
[0025] When used as a straight ruler, the movable ruler 2 only needs to rotate to completely coincide with the fixed ruler 1; when used as a direction pointer, rotate the movable ruler 2 around the rotating shaft until the limiting column 6 blocks the movable ruler 2. At this time, the movable ruler 2 is perpendicular to the fixed ruler 1. According to the compass on the geographical map, place the N direction on the movable ruler in the same direction as the compass pointer, and then the relative orientation on the map can be easily judged, enabling students to better understand the map and direction, and increasing their learning interest.
[0026] The above is only the preferred embodiment of the utility model patent, and it is not used to limit the utility model patent. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the utility model patent shall be included in the protection scope of the utility model patent.
