Description

Technical Field

[0001] The utility model relates to the technical field of propaganda equipment, in particular to a portable propaganda device used for rural revitalization propaganda. Background Art

[0002] The contradiction between the ever-growing needs of our people for a better life and the unbalanced and inadequate development is most prominent in rural areas. Our country is still in and will remain in the primary stage of socialism for a long time, and its characteristics are largely reflected in rural areas, but the transmission of knowledge received by rural areas is slow.

[0003] Therefore, the dissemination of knowledge in rural areas is extremely important. When promoting the rural revitalization strategy, propaganda devices are usually needed to facilitate the dissemination and transmission of knowledge in rural areas.

[0004] In the process of using the preaching device, refer to the patent document CN215423359U. The device proposed in the patent document can be suitable for people of different heights to carry out preaching activities by setting two standing boards, thereby making the device more applicable. By setting a retractable microphone, it is convenient to carry the device and protect the microphone when not in use. However, in the actual use of the preaching device, although the device can be convenient for people of different heights to preach, the height of the preaching device is relatively fixed, and the size is large and not convenient to carry and carry. In addition, the preacher needs to stand on the platform to preach. If the preacher walks, there is a risk of falling. For this reason, we provide a portable preaching device for rural revitalization preaching to solve the above problems. Utility Model Content

[0026] refer to Figures 1 to 4 The first telescopic frame 201 and the second telescopic frame 202 are arranged in a sliding connection manner, so that the second telescopic frame 202 can be slid to the periphery of the first telescopic frame 201, thereby greatly saving space, greatly improving space utilization, and facilitating transportation and carrying. The height of the second telescopic frame 202 can be adjusted by subsequent driving components, greatly improving the practicality of the device.

[0027] The upper surface of the first fixed plate 203 is fixedly connected with a sliding rod 3 in an annular array, and the outer surface of the sliding rod 3 is slidably connected with a sliding cylinder 4, and the upper end of each sliding cylinder 4 is fixedly connected to the bottom surface of the second fixed plate 204. By arranging the sliding rod 3 and the sliding cylinder 4, the second fixed plate 204 can be better supported and stabilized, and the movement load of the threaded rod 207 and the threaded cylinder 208 can be greatly reduced, and the second fixed plate 204 can also be limited in movement to avoid the risk of bending and breaking between the second fixed plate 204 and the threaded cylinder 208 due to a large load.

[0028] The outer surface of each slide bar 3 is sleeved with a telescopic spring 5, and the telescopic spring 5 is located between the side of the slide cylinder 4 and the first fixed plate 203 that are close to each other.
