[0002] As an effective on-site display and mobile publicity tool, science popularization boards play an important role in various science popularization activities. Traditionally, these science popularization boards usually need to have the characteristics of being easy to fix and display, so as to be used in different locations and conditions. To meet the needs of daily use, the design of science popularization boards often takes into account factors such as convenient erection and disassembly, good stability, and easy portability.

[0003] At present, the science popularization boards on the market are mainly divided into two types: one is with a fixed bracket, and the other is equipped with a detachable bracket. The science popularization board with a fixed bracket has certain limitations in terms of portability. During transportation, it often needs to occupy a large space, which undoubtedly increases the logistics cost and the inconvenience of carrying.

[0004] The science popularization board with a detachable bracket, although it solves the problems of transportation and storage space to a certain extent, often faces problems such as cumbersome operation and long time consumption during the actual erection and disassembly process, which affects the work efficiency.

[0005] Based on the pain points of the above two types of science popularization boards, those skilled in the art proposed a mobile science popularization board. Content of the Utility Model

[0006] In view of the above problems existing in the prior art, the main purpose of the present utility model is to provide a mobile science popularization board.

[0007] The technical solution of the present utility model is as follows: A mobile science popularization board includes a display board. A through groove is opened inside the display board. Two optical rods are symmetrically and fixedly connected inside the through groove. The outer sides of the optical rods are both slidably connected with sliding sleeves. Through holes are opened on the outer sides of the sliding sleeves and the optical rods. A long rod is connected between the corresponding two through holes. The long rod is provided with an external thread and is limited by a nut. The first rotating rods are rotatably connected to the sides of the two sliding sleeves away from each other. A bottom plate is fixedly connected to the bottom of the display board. The second rotating rods are rotatably connected to both ends of the bottom plate.

[0008] As a preferred implementation manner, the corresponding second rotating rods are rotatably connected to the first rotating rods. Connecting rods are fixedly connected to the sides of the two second rotating rods away from each other. The third rotating rods are rotatably connected to the outer sides of the connecting rods.

[0009] As a preferred embodiment, fixing plates are fixedly connected to one side of each of the second rotating rods. Connecting holes are formed in the fixing plates, the second rotating rods and the third rotating rods, and the third rotating rods are connected to the corresponding connecting holes through screws.

[0010] As a preferred embodiment, rollers are connected to the bottoms of the third rotating rods and the bottom plate, and the rollers at the bottom of the bottom plate are universal wheels.

[0011] As a preferred embodiment, a magnetic attraction plate is formed on the outer side of the display board.

[0012] Compared with the prior art, the advantages and positive effects of the present utility model are as follows:

[0013] By rotating between the first rotating rod and the second rotating rod, the present device can be unfolded and contracted. After display, the bottom of the whole device can form a triangular structure. Through the setting of the triangular structure, the device can be stably placed. When movement is required, by rotating the third rotating rod, the rollers at its bottom are in contact with the ground, so that the device can be moved. Compared with the traditional popular science display board, through the structural changes provided, the present device can be stably placed and can also be moved. When not in use, the structure can be contracted to ensure the flatness of the present device, which can greatly reduce the space occupation problem, facilitate later transportation and movement, and the overall operation is convenient. The user only needs to perform simple operations to complete. BRIEF DESCRIPTION OF THE DRAWINGS
