Description

Technical Field

[0001] This utility model relates to the field of display device technology, specifically an improved structure for a land space planning layout display device. Background Technology

[0002] Territorial spatial planning layout is the spatial arrangement of land and other resources. When making the layout, the layout results need to be displayed through display boards. Territorial spatial planning layout display devices are the equipment that display the layout plan to the public.

[0003] Utility model patent CN222233264U discloses a land spatial planning layout display device, comprising: a base frame, universal wheels movably mounted at the four corners of the bottom of the base frame, cylinders fixedly mounted at the four corners of the top of the base frame, a storage box fixedly connected between the output ends of the cylinders, and a display panel movably mounted inside the storage box via bearings; this utility model achieves the purpose of adjusting the tilt angle of the display panel through the cooperation of an electric telescopic rod, a sliding plate, a rack and pinion, and gears. During display, the electric telescopic rod drives the sliding plate to move back and forth, the rack on one side of the sliding plate drives the gear to rotate, and the gear drives the display panel to rotate along the axis of the display panel. This structure can change the display angle of the display panel according to needs, making the device more flexible.

[0004] However, when adjusting the angle of the aforementioned land and space planning layout display device, both sides of the electric telescopic rods need to work together to adjust the angle of the display panel. At the same time, when the device is raised or lowered, the four cylinders at the bottom also need to work synchronously to achieve the height adjustment effect. This will lead to increased energy consumption and high control complexity. Utility Model Content

[0005] To overcome the shortcomings of existing technologies, this utility model proposes an improved structure for a land spatial planning layout display device to solve the problems existing in current land spatial planning layout displays.

[0006] The technical solution adopted by this utility model to solve its technical problem is:

[0007] An improved structure for a land spatial planning layout display device includes a mounting plate, the top of which is provided with an angle adjustment mechanism, an expansion mechanism and a clamping mechanism, and the bottom of which is provided with a height adjustment mechanism;

[0008] The angle adjustment mechanism includes a base fixed to the top of a mounting plate. Two connecting blocks are fixed to the front side of the base surface, and a combined plate is hinged to the surface of each connecting block. Two mounting frames are fixed to the top rear side of the base surface, and a partition is fixed between the two mounting frames. A first lead screw is threaded through the surface of the partition, and a slider is rotatably connected to one end of the first lead screw. The slider is slidably connected to the surface of the base. Connecting rods are fixed to both sides of the slider surface, and the connecting rods are slidably connected to the inner wall of the mounting frame. A drive plate is hinged to the surface of the connecting rod, and the drive plate is hinged to the bottom of the combined plate.

[0009] Preferably, the extension mechanism includes two extension plates, the surface of the combined plate is provided with a mounting groove, the extension plate is slidably connected to the surface of the mounting groove, and a pull handle is fixed to one side surface of the extension plate.

[0010] Preferably, the height adjustment mechanism includes a support leg, a horizontal plate fixed to the surface of the support leg, a movable leg slidably connected to the top of the inner wall of the support leg, the top of the movable leg being fixedly connected to the bottom of the mounting plate, and a second lead screw threaded through the surface of the horizontal plate, the second lead screw being rotatably connected to the bottom of the mounting plate.

[0011] Preferably, guide plates are fixed on opposite sides of the inner wall of the mounting groove, and guide grooves are provided on both the front and rear sides of the surface of the extension plate, with the guide plates slidably connected to the surfaces of the guide grooves.

[0012] Preferably, connecting plates are fixed on both the left and right sides of the combined plate surface, and pins slide through the surface of the connecting plates. The top of the extension plate has multiple pin slots for inserting the mating pins.

[0013] Preferably, the clamping mechanism includes a mating plate, which is fixed to the surface of the extension plate. A shank bolt is threaded through the surface of the mating plate, and a clamping plate is rotatably connected to one end of the shank bolt. A rubber pad is fixed to the surface of the clamping plate.

[0014] Preferably, two guide rods slide through the surface of the mating plate, and one end of each guide rod is fixedly connected to the surface of the clamping plate.

[0015] Compared with existing technologies, the beneficial effects of the improved structure of this utility model's land spatial planning layout display device are:

[0016] First, the coordinated design of the angle adjustment mechanism and the height adjustment mechanism significantly enhances the flexibility and practicality of the display device. The angle adjustment mechanism adopts a single-sided screw drive, replacing the traditional method of synchronous operation of two electric telescopic rods. This not only simplifies the control logic and reduces energy consumption caused by multiple power sources synchronizing, but also ensures precise and long-term stability of the display angle thanks to the self-locking and stability of the screw drive. The height adjustment mechanism also uses the screw drive principle, abandoning the complex structure of four cylinders for synchronous lifting. It only requires a single second screw to drive smooth lifting and lowering, greatly reducing energy consumption. The energy-saving effect is particularly obvious in scenarios where the height is frequently adjusted. The combination of the two mechanisms allows the display device to quickly adapt to different venues and audience viewing angles, greatly enhancing the display effect and applicability.

[0017] Secondly, the extension plate of the expansion mechanism achieves flexible expansion of the display area through sliding fit and guide structure. With the help of pins for multi-position fixing, it can be freely adjusted according to the size of the exhibits, effectively utilizing space and being easy to operate. The threaded clamping method of the clamping mechanism, combined with rubber pad protection, can not only firmly fix the exhibits, but also avoid damage to the exhibits caused by traditional pasting or nailing methods. The guide rod ensures a smooth clamping process and is suitable for the quick replacement and display of exhibits of different thicknesses. Attached Figure Description

[0025] The specific embodiments of this utility model will now be described in further detail with reference to the accompanying drawings.

[0026] For an improved structure of a land spatial planning layout display device under this specific implementation, please refer to [link / reference needed]. Figures 1-6 It includes a mounting plate 1, with an angle adjustment mechanism 2, an expansion mechanism 3 and a clamping mechanism 5 on the top of the mounting plate 1, and a height adjustment mechanism 4 on the bottom of the mounting plate 1;

[0027] The angle adjustment mechanism 2 includes a base 201, which is fixed to the top of the mounting plate 1. Two connecting blocks 202 are fixed to the front side of the surface of the base 201. A combination plate 203 is hinged to the surface of the connecting blocks 202. Two mounting frames 204 are fixed to the top of the rear side of the surface of the base 201. A partition plate 205 is fixed between the two mounting frames 204. A first lead screw 206 is threaded through the surface of the partition plate 205. A slider 207 is rotatably connected to one end of the first lead screw 206. The slider 207 is slidably connected to the surface of the base 201. Connecting rods 208 are fixed to both the left and right sides of the surface of the slider 207. The connecting rods 208 are slidably connected to the inner wall of the mounting frame 204. A drive plate 209 is hinged to the surface of the connecting rod 208. The drive plate 209 is hinged to the bottom of the combination plate 203.

[0028] With the above technical solution, when the first lead screw 206 rotates, the slider 207 drives the connecting rod 208 and the drive plate 209 to move, thereby causing the combined plate 203 to flip around the hinge of the connecting block 202 to achieve angle adjustment. This structure, through the threaded transmission between the first lead screw 206 and the slider 207, only requires a single-sided drive to achieve the pitch angle adjustment of the combined plate 203, avoiding the complex control of synchronous cooperation of the electric telescopic rods on both sides in the prior art, reducing energy consumption and simplifying the operation process. At the same time, the lead screw transmission has self-locking properties, which can stably maintain the set angle and ensure the continuity of the display effect.

[0029] The extension mechanism 3 includes two extension plates 301. The surface of the combination plate 203 is provided with a mounting groove 302. The extension plates 301 are slidably connected to the surface of the mounting groove 302. A pull handle 303 is fixed on one side of the extension plate 301.

[0030] With the above technical solution, by pulling the handle 303, the extension plate 301 can slide out or retract along the mounting groove 302, thereby flexibly adjusting the display area. This design achieves the expansion of the display area through simple sliding cooperation, which is convenient to operate and can be adjusted at any time according to actual display needs, effectively utilizing space.

[0031] The height adjustment mechanism 4 includes a support leg 401, a horizontal plate 402 fixed on the surface of the support leg 401, a movable leg 403 slidably connected to the top of the inner wall of the support leg 401, the top of the movable leg 403 being fixedly connected to the bottom of the mounting plate 1, and a second lead screw 404 threaded through the surface of the horizontal plate 402, the second lead screw 404 being rotatably connected to the bottom of the mounting plate 1.

[0032] With the above technical solution, when the second lead screw 404 is rotated, the movable support leg 403 slides up and down along the inner wall of the support leg 401, thereby changing the height of the mounting plate 1 and realizing the height adjustment of the entire device. The height adjustment by using lead screw transmission has high precision and stability. Only a single lead screw is needed to complete the lifting operation, eliminating the need for four cylinders to work synchronously, which greatly reduces energy consumption and simplifies the control logic.

[0033] Guide plates 304 are fixed on opposite sides of the inner wall of the mounting groove 302, and guide grooves 305 are provided on the front and rear sides of the surface of the extension plate 301. The guide plates 304 and the guide grooves 305 are slidably connected.

[0034] Through the above technical solution, during the sliding process of the extension plate 301, the guide plate 304 slides in the guide groove 305, which plays a guiding and limiting role, ensuring that the extension plate 301 extends or retracts smoothly into the mounting groove 302.

[0035] Connecting plates 306 are fixed on both the left and right sides of the surface of the composite plate 203. A pin 307 slides through the surface of the connecting plate 306. Multiple pin slots 308 are opened at the top of the extension plate 301 to accommodate the pin 307.

[0036] With the above technical solution, when the extension plate 301 slides to the appropriate position, the pin 307 is inserted into the corresponding pin groove 308 to fix the position of the extension plate 301.

[0037] The clamping mechanism 5 includes a mating plate 501, which is fixed to the surface of the extension plate 301. A shank bolt 502 is threaded through the surface of the mating plate 501. One end of the shank bolt 502 is rotatably connected to a clamping plate 503. A rubber pad 504 is fixed to the surface of the clamping plate 503.

[0038] With the above technical solution, when rotating the shank bolt 502, the clamping plate 503 moves closer to or further away from the mating plate 501, and the rubber pad 504 applies clamping force to the exhibit, thereby achieving stable clamping of exhibits of different thicknesses.

[0039] Two guide rods 505 slide through the surface of the mating plate 501, and one end of the guide rod 505 is fixedly connected to the surface of the clamping plate 503.

[0040] With the above technical solution, when the shank bolt 502 rotates and drives the clamping plate 503 to move, the guide rod 505 slides on the surface of the mating plate 501, ensuring that the clamping plate 503 moves in a straight line, thereby improving the stability and accuracy of the clamping process.

[0041] Its working principle is as follows: First, the overall height of the device is adjusted by the height adjustment mechanism 4. The second lead screw 404 is rotated so that it rotates in the threaded hole of the horizontal plate 402. At the same time, because the second lead screw 404 is rotatably connected to the bottom of the mounting plate 1, the movable support leg 403 will slide on the inner wall of the support leg 401, thereby changing the height of the mounting plate 1. After reaching the desired display height, the rotation stops, and the lead screw self-locks to fix the height. Next, the display angle of the combined plate 203 is adjusted by the angle adjustment mechanism 2. The first lead screw 206 is rotated, and the slider 207 slides along the surface of the base 201, driving the connecting rod 208 and the drive plate 209 to move. The drive plate 209 pushes the combined plate 203 to flip around the hinge of the connecting block 202. Once the desired angle is reached, the lead screw self-locks to maintain the angle. If the display area needs to be expanded, pull the handle 303 of the extension plate 301 to slide it out along the mounting groove 302. The guide plate 304 slides smoothly in the guide groove 305. After sliding to the appropriate position, insert the pin 307 into the corresponding pin groove 308 for fixation. When displaying exhibits, rotate the bolt with handle 502. The clamping plate 503 moves linearly under the guidance of the guide rod 505. The rubber pad 504 contacts the exhibit and applies clamping force to complete the fixation of the exhibit. The entire device operates smoothly from installation to display. The various mechanisms cooperate with each other and achieve multi-functional adjustment through simple mechanical transmission. It does not require complex electrical control or multiple power sources operating simultaneously, thus reducing energy consumption and control difficulty.

[0042] It should be noted that, although specific embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these specific embodiments without departing from the principles and spirit, the scope of which is defined by the appended claims and their equivalents.
