[0023] The specific embodiments of this utility model will now be described in further detail with reference to the accompanying drawings.

[0024] Please see Figure 1-6 An adjustable display board for promoting natural resource planning includes an active base 1, a support column 2 fixed to the top of the active base 1, an expansion mechanism 3 at the top of the support column 2, four display mechanisms 4 at the top of the expansion mechanism 3, and a drive mechanism 5 inside the expansion mechanism 3.

[0025] The expansion mechanism 3 includes a mounting cylinder 301, which is fixed to the top of the support column 2. A rotating shaft 302 is rotatably connected to the inner wall of the mounting cylinder 301. A turntable 303 is fixed to the surface of the rotating shaft 302. Four arc-shaped grooves 304 are formed on the surface of the turntable 303. Rollers 305 are rotatably connected to the inner wall of the arc-shaped grooves 304. A movable block 306 is rotatably connected to the top of the rollers 305. Four sliding grooves 307 are formed on the top of the mounting cylinder 301. The movable block 306 is slidably connected to the surface of the sliding grooves 307.

[0026] Through the above technical solution, the display mechanism 3 is located on top of the expansion mechanism 4, and the drive mechanism 5 is inside the expansion mechanism 3. The drive mechanism 5 can drive the rotating shaft 302 to rotate the turntable 303. The roller 305 in the arc groove 304 on the turntable 303 rolls accordingly, pushing the movable block 306 to slide along the slide groove 307, thereby changing the distance between the four display mechanisms 4 at the top. This allows the distance between multiple display mechanisms 4 to be changed, avoiding collisions when unfolded. This structural design enables the display mechanism 4 to adapt to display needs of different sizes, effectively expanding the range of drawings applicable to the equipment, improving the display effect and practicality of the equipment, and providing a more efficient and convenient display platform for natural resource planning and publicity.

[0027] The display mechanism 4 includes a support plate 401. The bottom of the support plate 401 is fixedly connected to the top of the movable block 306. An installation groove 402 is provided on the surface of the support plate 401. Two placement plates 403 are slidably connected to the surface of the installation groove 402. Multiple universal balls 412 are fixed to the bottom of the support plate 401. The surface of the universal balls 412 is slidably connected to the top of the mounting cylinder 301.

[0028] With the above technical solution, when the expansion mechanism 3 adjusts the position of the display mechanism 4, the universal ball 412 can make the support plate 401 slide stably and the placement plate 403 slide in the mounting groove 402. The position can be adjusted according to the actual drawing size to better display the drawing.

[0029] A metal plate 404 is fixed to the surface of the placement plate 403, and a magnet 405 for fixing the drawing is magnetically attracted to the surface of the metal plate 404.

[0030] With the above technical solution, when it is necessary to display drawings, the drawings are placed on the metal plate 404 and attracted to the metal plate 404 by the magnet 405, thereby fixing the drawings in place and preventing them from shifting or falling during the display process.

[0031] The drive mechanism 5 includes a side block 501, which is fixed to the bottom of the inner wall of the mounting cylinder 301. A worm 502 is rotatably connected to the surface of the side block 501. A worm wheel 503 meshes with the surface of the worm 502. The worm wheel 503 is fixed to the surface of the rotating shaft 302. One end of the worm 502 passes through the mounting cylinder 301 and is fixed with a handle 504.

[0032] Through the above technical solution, when the handle 504 is turned, the worm gear 502 rotates, driving the worm wheel 503 and the rotating shaft 302 to rotate, thereby causing the turntable 303, roller 305 and movable block 306 in the expansion mechanism 3 to move, thereby changing the distance between the display mechanisms 4.

[0033] A support ring 308 is fixed to the inner wall of the mounting cylinder 301. A circular slide rail 309 is fixed to the top of the support ring 308. Multiple sliders 310 are slidably connected to the top of the circular slide rail 309. The top of the sliders 310 is fixedly connected to the bottom of the turntable 303.

[0034] With the above technical solution, when the rotating shaft 302 drives the turntable 303 to rotate, the slider 310 slides on the circular slide rail 309, providing stable support for the rotation of the turntable 303, ensuring the smooth rotation of the turntable 303, and thus ensuring the stable movement of the movable block 306 and the display mechanism 4.

[0035] Guide plates 406 are fixed on both the upper and lower sides of the inner wall of the bearing plate 401, and guide grooves 407 are opened on the surface of the placement plate 403. The guide plates 406 and guide grooves 407 are slidably connected.

[0036] With the above technical solution, when the placement plate 403 slides in the mounting groove 402, the guide plate 406 slides in the guide groove 407, which plays a guiding and limiting role, ensuring that the placement plate 403 moves smoothly and accurately, and preventing the placement plate 403 from deviating or getting stuck during the sliding process.

[0037] Both sides of the upper surface of the bearing plate 401 are fixed with extension plates 408. The extension plates 408 are threaded with shank bolts 409. The bottom of the shank bolts 409 is fixed with pin blocks 410. The top of the placement plate 403 is provided with multiple pin slots 411 for inserting the mating pin blocks 410.

[0038] With the above technical solution, after the placement plate 403 is adjusted to the appropriate position, tighten the handle bolt 409 so that the pin block 410 is inserted into the pin groove 411, thereby fixing the placement plate 403 on the support plate 401 and preventing it from sliding during the display process.

[0039] Working principle: The movable base 1 serves as the equipment base, and the support column 2 supports the expansion mechanism 3. Inside the mounting cylinder 301 of the expansion mechanism 3, the rotating shaft 302 drives the turntable 303 to rotate. The rollers 305 in the arc groove 304 on the turntable 303 roll accordingly, pushing the movable block 306 to slide along the sliding groove 307, thereby changing the distance between the four display mechanisms 4 at the top. The bottom of the support plate 401 of the display mechanism 4 is connected to the movable block 306, and the position of the placement plate 403 in the mounting groove 402 on its surface can be adjusted by sliding. The smooth sliding is achieved by the cooperation of the guide plate 406 and the guide groove 407. After the position is adjusted, it is fixed by the extension plate 408, the bolt with handle 409, the pin block 410, and the pin groove 411; the placement plate 403 The metal plate 404 on the display mechanism 4 is magnetically attached to the magnet 405 to fix the drawing. The worm gear 502 and worm wheel 503 of the drive mechanism 5 drive the rotation of the shaft 302 by turning the handle 504, thereby changing the spacing of the display mechanism 4. When different sizes of drawings need to be displayed, first turn the handle 504 to adjust the expansion mechanism 3 through the drive mechanism 5 to make the spacing of the display mechanism 4 appropriate. Then place the drawing on the metal plate 404 of the display mechanism 4 and fix it with the magnet 405. If the drawing size is special, the placement plate 403 can be slid. After adjusting the position, tighten the bolt with handle 409 to fix it and complete the display preparation. The whole process is orderly and efficient, and the components work closely together to meet the display needs of natural resource planning drawings in different scenarios.
