[0029] The utility model is further described below in conjunction with the accompanying drawings:

[0030] like Figure 1-Figure 8 As shown, a field positioning marker pole for safe production in coal mines includes a survey marker column 100, which is vertically arranged and hollow inside. An adjustment mechanism 300 is arranged on the outer surface of the survey marker column 100, and a fixing mechanism 200 for fixing the survey marker column 100 is also included. The fixing mechanism 200 is distributed on the upper and lower sides of the survey marker column 100;

[0031] In this embodiment: the fixing mechanism 200 includes a fixing component, a pressing component, and a limiting component. The limiting component is used to control the pressing component to press down, so that the pressing component drives the fixing component to extend into the ground to fix the surveying marker column 100;

[0032] The pressing assembly includes a pressing rod 201 slidably mounted inside the surveying and marking column 100, an upper striking pad 203 is fixed to the upper end of the pressing rod 201, a lower striking pad 205 is fixed to the outer side of the surveying and marking column 100 near the opening, a telescopic rod 202 is arranged between the lower striking pad 205 and the upper striking pad 203, a stabilizing sleeve 204 is fixed to the outer side of the pressing rod 201 near the opening of the surveying and marking column 100, and the stabilizing sleeve 204 is slidably connected to the surveying and marking column 100, and is used to guide the up and down movement of the pressing rod 201, so that it is more stable when moving up and down;

[0033] The limit assembly includes a limit block 207, which is transversely arranged below the lower pressure rod 201, and is slidably connected to the survey mark column 100 in a transverse direction. A return spring is connected between the limit block 207 and the inner wall of the survey mark column 100, and a through groove 208 is provided at the center of the limit block 207. A limit groove 209 is provided on the outer surface of the lower pressure rod 201 near the through groove 208. The limit block 207 is slidably matched with the lower pressure rod 201, the diameter of the through groove 208 is larger than that of the lower pressure rod 201, and the lower end of the limit block 207 is arc-shaped;

[0034] The fixing assembly includes a rack 210 arranged at the lower end of the lower pressure rod 201, a cone 206 is fixed at the lower end of the surveying and marking column 100, and a fixing plate 213 is fixed on the inner walls of the front and rear sides of the surveying and marking column 100. Two arc grooves 214 are provided on the surface of the fixing plate 213 along the vertical direction, and a sliding column 215 is slidably installed in the arc groove 214, and an arc plug block 212 is fixed on the sliding column 215. Gears 211 are arranged on both sides of the rack 210, and the gear 211 is rotatably installed between the fixing plates 213 on the front and rear sides. A plurality of teeth are distributed on the arc plug block 212 near the gear 211. 12 is meshed with gear 211, gear 211 is meshed with rack 210, and the lower end of arc-shaped plug 212 is pointed. The staff drives the surveying marker column 100 to be inserted into the ground by hammering the downward pressure component. When the surveying marker column 100 enters the inside of the ground, the downward pressure component continues to move downward to cooperate with the fixing component, driving the two arc-shaped plugs 212 to slowly rotate and extend into the inside of the ground, thereby improving the gripping force between the surveying marker column 100 and the ground, increasing the friction, reducing the phenomenon of the surveying marker column 100 falling off due to human collision, and improving the fixing effect of the surveying marker column 100.

[0035] In this embodiment: the adjustment mechanism 300 includes a sliding sleeve 301 slidably mounted on the outer surface of the survey marker column 100, a plurality of insertion holes 302 are opened on the front side of the survey marker column 100, the sliding sleeve 301 and the insertion holes 302 are connected by bolts, a fixed sleeve 304 is fixed on one side of the sliding sleeve 301, a rotating rod 305 is installed inside the fixed sleeve 304, the rotating rod 305 is rotatably connected to the sliding sleeve 301, a fixing ring 307 is fixed on the outer surface of the rotating rod 305 near the fixing sleeve 304, and plug posts 308 are slidably mounted on both the front and rear sides of the fixing ring 307, the plug posts 308 and the fixing ring 307 are connected by springs, a plurality of limiting holes 303 are evenly distributed around the outer surface of the fixing sleeve 304, the plug posts 308 are plugged into the limiting holes 303, and the rotating rod 30 A sign 306 is fixed on the side away from the fixing sleeve 304. The sign 306 is moved up and down by moving the sliding sleeve 301 to adjust the height of the sign 306. When the height is adjusted to a suitable height, the bolt is turned to lock the sliding sleeve 301 on the surface of the surveying and marking column 100. Then, the sign 306 is rotated by pressing the plug posts 308 on the front and rear sides, driving the rotating rod 305 to rotate, driving the fixing ring 307 to rotate, and driving the two plug posts 308 to rotate. When the rotation reaches a suitable angle, the rotation is stopped, and the pressing of the two plug posts 308 is stopped, so that the two plug posts 308 pop out and plug into the limiting holes 303 on the fixing sleeve 304, the rotating rod 305 is fixed, and the angle of the sign 306 is fixed, thereby improving the flexibility of the device.

[0036] Working principle: When the staff conducts survey, the surveying marker column 100 is needed to mark the measured distance, level or orientation of the surveying area, so as to facilitate the staff to navigate the surveying area. The staff hammers the upper striking pad 203, and the upper striking pad 203 drives the lower pressure rod 201 to move downward inside the surveying marker column 100. Since the limiting groove 209 on the lower pressure rod 201 abuts against the through groove 208 on the limiting block 207, the limiting block 207 blocks the lower pressure rod 201 from moving downward, so that the hammering force is transmitted to the surveying marker column 100 through the lower pressure rod 201 and the limiting block 207, driving the surveying marker column 100 to be slowly inserted into the ground;

[0037] When the surveying marker column 100 is slowly inserted, the limit block 207 is driven to move toward the ground. When the limit block 207 touches the ground, a state of mutual extrusion is formed between the limit block 207 and the ground, which drives the limit block 207 to shrink toward the inside of the surveying marker column 100, so that the through groove 208 on the limit block 207 and the limit groove 209 on the pressing rod 201 are disengaged from each other, so that the limit block 207 no longer blocks the pressing rod 201 from pressing downward;

[0038] The downward pressure of the pressing rod 201 continues to drive the rack 210 to move downward, and the rack 210 meshes with the gears 211 on both sides, driving the gears 211 on both sides to rotate, and the gears 211 mesh with the arc plug block 212, driving the arc plug block 212 to rotate in the arc groove 214 on the fixing plate 213, so that the arc plug blocks 212 on both sides slowly extend outward and are inserted into the ground, increasing the friction between the ground and the gripping force between the arc plug block 212 and the ground, thereby improving the fixing effect of the surveying marker column 100 inside the ground;

[0039] After the survey marker column 100 is fixed, the sliding sleeve 301 is moved to drive the identification plate 306 to move up and down, and the height of the identification plate 306 is adjusted. When it is adjusted to an appropriate height, the bolt is turned to lock the sliding sleeve 301 on the surface of the survey marker column 100, and then the identification plate 306 is rotated by pressing the front and rear sides of the plug posts 308, which drives the rotating rod 305 to rotate, drives the fixing ring 307 to rotate, and drives the two plug posts 308 to rotate. When it rotates to an appropriate angle, the rotation is stopped, and the pressing of the two plug posts 308 is stopped, so that the two plug posts 308 pop out and connect with the limiting holes 303 on the fixing sleeve 304, fix the rotating rod 305, fix the angle of the identification plate 306, and complete the installation of the survey marker column 100.

Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model.
