[0026] See also Figure 1-4 A three-dimensional visual communication display board includes a protective cover 1, a mounting frame 2 is arranged inside the protective cover 1, and a fixing column 3 is fixedly connected to the inner bottom wall of the protective cover 1.

[0027] The protective cover 1 is made of glass with relatively high hardness, which can protect the posters on the mounting frame 2 without affecting the viewing of pedestrians and avoiding breakage when hit, thereby increasing the safety of the device. The mounting frame 2 is magnetic and can attract the magnet.

[0028] A second guide rod 14 is fixedly connected to the inner bottom wall of the protective cover 1, and a limiting plate 15 is fixedly connected to the top of the second guide rod 14. A second guide block 16 is sleeved on the outer surface of the second guide rod 14, and the outer surface of the second guide block 16 is fixedly connected to the outer surface of the mounting frame 2. The second guide rod 14, the limiting plate 15 and the second guide block 16 can be used to limit the mounting frame 2 to avoid position displacement of the mounting frame 2 during use, which can make the operation more convenient and quick for the staff. The limiting plate 15 can prevent the second guide block 16 from sliding out of the second guide rod 14, which can effectively increase the safety of the device.

[0029] The bottom surface of the protective cover 1 is fixedly connected to a base 17, and the bottom surface of the base 17 is installed with universal wheels 18 in a circular array. The outer surface of the universal wheels 18 is provided with anti-skid grooves. The base 17 can support the protective cover 1 and enable the protective cover 1 to be lifted off the ground. Because it is relatively humid outdoors, long-term contact with the ground may cause rust. The universal wheels 18 can make it more convenient and quick for workers to move the device. The anti-skid grooves on the outer surface of the universal wheels 18 can increase the grip of the device and effectively prevent the device from slipping.

[0030] The inner bottom wall of the base 17 is fixedly connected to a rotating motor 19, and the output end of the rotating motor 19 passes through the inner top wall of the base 17 and is fixedly connected to the bottom surface of the protective cover 1. The upper surface of the protective cover 1 is hinged with a sealing cover 20 through a pin shaft. The rotating motor 19 can drive the protective cover 1 to rotate, so that the device can display the poster more comprehensively. The rotating motor 19 is an existing device and a common motor on the market. The model of the rotating motor 19 is not excessively limited in this application. The sealing cover 20 can seal the protective cover 1.

[0031] A handle 12 is hinged on the upper surface of the fixing plate 401 through a pin shaft, and a protective cover is provided on the outer surface of the handle 12. A magnet 13 is provided on the mounting frame 2. The handle 12 can make it more convenient and quick for the staff to pull the mounting frame 2 to rise. The protective cover provided on the outer surface of the handle 12 can protect the palms of the staff and increase the comfort. The poster can be fixed to the mounting frame 2 through the magnet 13. The magnet 13 is magnetic and can be adsorbed on the mounting frame 2.

[0032] A limiting mechanism 4 is arranged inside the protective cover 1, and the limiting mechanism 4 includes a fixing plate 401 fixedly connected to the upper surface of the mounting frame 2. The fixing plate 401 needs to be made of a material with high hardness, because when the mounting frame 2 is pulled upward, the weight needs to be borne by the fixing plate 401, so in order to avoid the fixing plate 401 from breaking, it needs to be made of a material with high hardness, which can increase the safety and service life of the device.

[0033] The inner wall of the fixed plate 401 is slidably connected with a slider 402, and the bottom surface of the slider 402 is hinged with a hinge column 403 through a pin shaft. A lifting plate 404 is arranged inside the fixed column 3, and the bottom end of the hinge column 403 is hinged with the upper surface of the lifting plate 404 through a pin shaft.

[0034] The movement of the lifting plate 404 can drive the hinge column 403 to move, and then drive the slider 402 to slide inside the fixed plate 401. A guide mechanism is installed between the slider 402 and the fixed plate 401 to prevent the slider 402 from getting stuck during the sliding process. The slider 402 is made of waterproof and moisture-proof material. Because the humidity is high on rainy days outdoors, if the slider 402 is rusted, it will not be able to slide.

[0035] The bottom surface of the slider 402 is fixedly connected to a connecting rod 405, the inner wall of the mounting frame 2 is fixedly connected to a telescopic rod 406, the upper surface of the telescopic rod 406 is fixedly connected to the bottom end of the connecting rod 405, the output end of the telescopic rod 406 is fixedly connected to a moving frame 407, the inner wall of the moving frame 407 is fixedly connected to an insertion rod 408, and the outer surface of the fixed column 3 is provided with a socket 409, and the insertion rod 408 is plugged into the socket 409.

[0036] As the slider 402 moves, the telescopic rod 406 can be driven to move through the connecting rod 405, and then the insertion rod 408 can be driven to disengage from the inside of the socket 409 through the moving frame 407, so that the limit on the mounting frame 2 can be released. When the mounting frame 2 is fully pulled out, the insertion rod 408 needs to be inserted into the upper socket 409. At this time, the weight of the mounting frame 2 will be borne by several insertion rods 408, so the insertion rod 408 needs to be made of high-hardness alloy material to increase the bearing capacity while avoiding rust. The moving frame 407 is compatible with the amino grass on the fixed column 3, which can guide the sliding of the moving frame 407 and make the movement of the device smoother.

[0037] After the mounting frame 2 is limited, the required posters can be installed on different boards of the mounting frame 2, thereby realizing the installation and replacement of the mounting frame 2, and effectively improving the work efficiency of the staff.

[0038] A first guide rod 5 is provided inside the fixed column 3, and a first guide block 6 is slidably connected to the outer surface of the first guide rod 5. A connecting column 7 is fixedly connected to the outer surface of the lifting plate 404. An end of the connecting column 7 away from the lifting plate 404 is fixedly connected to a side of the first guide block 6 close to the lifting plate 404. The first guide rod 5, the first guide block 6 and the connecting column 7 can limit the lifting plate 404 so that the lifting plate 404 can only be lifted vertically. The outer surface of the first guide rod 5 is polished to reduce the wear caused by the sliding of the first guide block 6 and increase the service life of the device.

[0039] A lifting column 8 is fixedly connected to the upper surface of the fixed column 3. The top of the lifting column 8 passes through the fixed plate 401 and extends to the upper part of the fixed plate 401. A lifting plate 9 is fixedly connected to the upper surface of the lifting column 8. The lifting plate 404 can be moved by the movement of the lifting column 8 and the lifting plate 9. The lifting column 8 is made of waterproof and rust-proof material. Because the outdoors is relatively humid, if the lifting column 8 rusts after long-term use, it may become unable to slide.

[0040] A pull ring 11 is fixedly connected to the upper surface of the lifting plate 9, and a slide rod 10 is fixedly connected to the inner wall of the fixed plate 401. The outer surface of the slide rod 10 is slidably connected to the hole of the slider 402. The pull ring 11 can make it more convenient and quick for the staff to pull the lifting plate 9. The outer surface of the lifting plate 9 is provided with anti-slip grooves to effectively prevent the staff from slipping. The slide rod 10 can limit the slider 402, which can effectively increase the stability of the slider 402 when sliding.

[0041] The specific implementation process of the utility model is as follows: when using the device, the poster needs to be installed first, the sealing cover 20 needs to be opened first, and then the pull ring 11 can be pulled to drive the lifting plate 9 to move. As the lifting plate 9 moves, the lifting plate 404 can be driven to move through the lifting column 8, and then the slider 402 can be driven to slide inside the fixed plate 401 through the hinge column 403. As the slider 402 slides, the connecting rod 405 can be driven to move, and then the telescopic rod 406 can be driven to retract. As the telescopic rod 406 moves, the moving frame 407 can be driven to move. As the moving frame 407 moves, the insertion rod 408 can be driven to move, so that the insertion rod 408 can slide out of the insertion hole 409 at the lower part of the limiting mechanism 4, so that the limit of the mounting frame 2 can be released, and then the handle 12 can be pulled. , as the handle 12 moves, the fixed plate 401 can be driven to move, and then the lifting plate 404 can be driven to move through the hinge column 403, so that the first guide rod 5, the first guide block 6 and the connecting column 7 can be driven to move upward as a whole. At the same time, because the fixed plate 401 is fixedly connected to the mounting frame 2, the mounting frame 2 can be driven to rise as the fixed plate 401 rises. When the mounting frame 2 is lifted out, the lifting plate 9 is pressed down, and then the insertion rod 408 can be inserted into the inside of the insertion hole 409, so as to complete the positioning of the mounting frame 2, and then the handle 12 can be released, and then the poster can be fixed to the mounting frame 2 through the magnet 13, and then the reverse operation can be performed to move the mounting frame 2 downward, so as to complete the installation and replacement of the mounting frame 2, and then the device can be pushed to the required position, and then the rotating motor 19 is turned on to drive the protective cover 1 to rotate, so as to achieve the purpose of three-dimensional display.
