[0029] To make the above objects, features, and advantages of the present utility model more obvious and understandable, the present utility model will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0030] Referring to Figures 1 to 8 as shown, the present utility model provides a military map standing and target point positioning scale, including

[0031] a target scale 1, with a first connection part opened in the middle of the target scale 1, and auxiliary scoring parts opened at both ends of the target scale 1, and the auxiliary scoring parts are symmetrically arranged on both sides of the first connection part;

[0032] an aiming rod 2, with a second connection part arranged at the bottom end of the aiming rod 2, and the aiming rod 2 is detachably connected to the first connection part through the second connection part, and a first insertion part is arranged at the top end of the aiming rod 2;

[0034] For a further optimized solution, the first connecting portion includes a first fixing hole 7 opened in the middle of the target ruler 1. The inner side wall of the first fixing hole 7 is provided with an internal thread 12. The bottom end of the first fixing hole 7 communicates with a second fixing hole 8. The second connecting portion is detachably connected to the internal thread 12, and the auxiliary marking portion is arranged on both sides of the first fixing hole 7.

[0035] For a further optimized solution, the auxiliary marking portion includes two marking grooves 6. The two marking grooves 6 are symmetrically arranged on both sides of the first fixing hole 7. The marking grooves 6 are not communicated with the first fixing hole 7, and the marking grooves 6 penetrate through the target ruler 1 vertically.

[0036] For a further optimized solution, the second connecting portion includes an external thread 9 arranged at the bottom end of the outer side wall of the aiming rod 2. The external thread 9 is detachably connected to the internal thread 12. A fixed puncture needle 4 is fixedly connected to the bottom end of the aiming rod 2, and the fixed puncture needle 4 is adapted to the second fixing hole 8.

[0037] For a further optimized solution, the first plugging portion includes a fixing groove 10, and the fixing groove 10 is opened at the top end of the aiming rod 2.

[0038] For a further optimized solution, the second plugging portion includes a fixing key 11. The top end of the fixing key 11 is fixedly connected to one end of the bottom of the aiming needle 3, and the fixing key 11 is adapted to the fixing groove 10.

[0039] For a further optimized solution, the aiming portion includes an aiming opening 5, and the aiming opening 5 is opened at the top end of the aiming needle 3. The aiming opening 5 is arranged along the length direction of the aiming needle 3.

[0040] The marking groove 6 has a certain inclination to facilitate fixing a marking pencil, ensuring that the marking is in the exact middle of the marking groove 6.

The fixed puncture needle 4 can be conveniently inserted into the second fixing hole 8 to achieve quick replacement and matching. During use, first screw the external thread 9 at the bottom end of the aiming rod 2 onto the internal thread 12 of the first fixing hole 7, then insert the fixed puncture needle 4 into the second fixing hole 8, and then insert the fixing key 11 on the aiming needle 3 into the fixing groove 10 to complete the assembly. The utility model is convenient for storage, easy to assemble during use, and convenient to carry.

[0041] Referring to Figure 9 as shown, the utility model also provides a positioning method:

[0042] When training or in combat, place the military map on the pallet. First, determine the method for selecting the standing point O: ①Accurately calibrate the map: Place the compass ruler on the north and south virtual lines of the map, slowly rotate the map until the pointer of the compass coincides with the zero scale line (if the magnetic declination in this area is greater than 40 mils, correction is required); ②Select two points A and B that exist both on the map and in the field. First, insert the judgment ruler into the positioning point of point A, slowly rotate the judgment ruler until the aiming pointer and the center of point A in the field form a direction line, and draw a straight line towards the standing point O through the scoring groove 6 of the judgment ruler. Similarly, insert the judgment ruler at the map point B and the field point B according to the determination of point B on the map, so that the rear extension lines of direction line A and direction line B intersect at point O. Point O is the position of the standing point. The included angle α between the two direction lines is greater than 30° and less than 150°. If conditions permit, select a third point, that is, the field point C and the map point C, and draw direction lines backward. These three lines are checked through the intersection point O. When these three lines intersect at point O, the determination is correct, and the determination of the standing point is completed. Secondly, determine the method for the target point: ①Accurately calibrate the map: Place the compass ruler on the north and south virtual lines of the map, slowly rotate the map until the pointer of the compass coincides with the zero scale line (if the magnetic declination in this area is greater than 3 mils, correction is required); ②Insert the ruler at the standing point O so that the pointer of the judgment ruler coincides with the center of the field point A, and then draw a direction line A towards the target point; ③Use a telescope to determine the distance from the field point A to the standing point O (using the crosshair of the telescope to determine the mils of the height of the target point. Calculation method: height of the object in the field (m) / mils of the object determined by the telescope (mils) = kilometers; use a laser rangefinder for determination), and then convert it into the map distance from the standing point O to the map point A through the scale. With point o as the center and the converted map length as the radius, intercept a point on the direction line. This point is the position of the field point A on the map. The determination methods for other positions are the same as the above steps.
