Description

Technical Field

[0001] This application relates to the field of forestry and grassland science popularization technology, specifically a portable forestry and grassland science popularization device. Background Technology

[0002] Forestry and grassland science popularization devices are facilities or equipment that rely on forest and grassland resources to disseminate forestry and grassland scientific knowledge and ecological culture, and to showcase forestry and grassland scientific and technological achievements and ecological civilization practices. Using display screens to combine videos with text descriptions is a common way to popularize forestry and grassland science.

[0003] Currently, when using displays to popularize science, these displays are generally fixed in specific locations. Such fixed displays can only be used for science popularization near their installation location, making them inconvenient to move around flexibly, difficult to cover a wider area, and unable to better convey the importance of ecological restoration and related knowledge to the public. Utility Model Content

[0004] In view of this, the purpose of this utility model is to overcome the shortcomings of the prior art and propose a portable forestry and grassland science popularization device to solve the problems existing in the prior art.

[0005] To achieve the above objectives, this utility model provides a portable forestry and grassland science popularization device, including a storage box. The outer surface of the storage box is provided with a lifting rope, and a storage slot is opened inside the storage box. A cover plate is movably installed on the top of the storage box through an adjustment mechanism. A science popularization display screen is fixedly installed on the lower surface of the cover plate. A rubber sealing ring is provided on the outer surface of the science popularization display screen, and a locking mechanism is provided on the storage box.

[0006] Preferably, the adjustment mechanism includes a first damping shaft fixedly connected inside the storage box, an end swing bar rotatably connected to the outer surface of the first damping shaft, and a second damping shaft provided at the end of the end swing bar away from the first damping shaft. The adjustment mechanism can adjust the science display screen to a suitable position for operation (i.e., unfolding) or store it in the storage slot for carrying.

[0007] Preferably, an adjustment frame is rotatably connected to the outer surface of the second damping shaft, and a third damping shaft is provided at the end of the adjustment frame away from the second damping shaft. The outer surface of the third damping shaft is rotatably connected to the bottom of the cover plate.

[0008] Preferably, the locking mechanism includes a limiting frame fixedly connected to both ends of the cover plate, and a fixed platform is fixedly connected to both ends of the storage box. The locking mechanism can stably store the science display screen stored in the storage slot and seal it with the cover plate, thus facilitating stable carrying.

[0009] Preferably, a platform shaft is fixedly inserted through the inner side of the fixed platform, and a clamp plate is rotatably connected to the outer surface of the platform shaft. Both the fixed platform and the clamp plate are provided with arc surfaces to facilitate the placement of the limiting frame and its limiting and fixing.

[0010] Preferably, an arc-shaped buckle plate is fixedly connected to the outer surface of the clamp plate, and a limit buckle is rotatably connected to the outer surface of the fixing platform.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. When the science display screen is not in use, it can be easily stored in the storage slot inside the storage box using the damping shaft, end swing bar, and adjustment frame. This design not only saves space but also facilitates storage and transportation. The locking mechanism ensures that the cover plate can be stably locked onto the storage box, preventing the screen from shaking or falling off during transport. Finally, simply pull the lifting rope to easily carry the science popularization device.

[0013] 2. This portable forestry and grassland science popularization device can adjust the height and angle of the science popularization display screen through the adjustment mechanism. This means that whether on flat ground or slightly undulating terrain, or whether looking up, down, or at eye level, the best display angle can be found to ensure that the audience has a clear viewing angle, thereby better attracting the audience's attention and optimizing the viewing experience.

[0018] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0019] Please see Figure 1-3 A portable forestry and grassland science popularization device includes a storage box 1, a lifting rope 2 on the outer surface of the storage box 1, a storage slot 3 inside the storage box 1, a cover plate 9 movably installed on the top of the storage box 1 via an adjustment mechanism, a science popularization display screen 10 fixedly installed on the lower surface of the cover plate 9, a rubber sealing ring 11 on the outer surface of the science popularization display screen 10, the function of the rubber sealing ring 11 is to ensure that after the science popularization display screen 10 is placed in the storage slot 3, the rubber sealing ring 11 is in close contact with the inner wall of the storage box 1, thereby preventing external moisture from entering the storage slot 3 and achieving a sealing and protection effect, and a locking mechanism is provided on the storage box 1.

[0020] Through the above technical solution, the position of the science display screen 10 can be adjusted by the adjustment mechanism during use, so that it can display science information from different angles according to the needs of different environments and scenarios. It can also be stored in the storage slot 3 inside the storage box 1. With the help of the locking mechanism and the cover plate 9, it can be stably sealed. With the help of the lifting rope 2, it can be carried conveniently.

[0021] Specifically, the adjustment mechanism includes a first damping shaft 4 fixedly connected inside the storage box 1, an end swing bar 5 rotatably connected to the outer surface of the first damping shaft 4, and a second damping shaft 6 provided at the end of the end swing bar 5 away from the first damping shaft 4.

[0022] Through the above technical solution, all three sets of damping shafts have damping characteristics, and can remain relatively stable after the end swing bar 5 is turned to rotate along the first damping shaft 4 to the corresponding position.

[0023] Specifically, an adjustment frame 7 is rotatably connected to the outer surface of the second damping shaft 6, and a third damping shaft 8 is provided at the end of the adjustment frame 7 away from the second damping shaft 6. The outer surface of the third damping shaft 8 is rotatably connected to the bottom of the cover plate 9.

[0024] Through the above technical solution, the cover plate 9 can be adjusted along the third damping axis 8 to adjust the external display angle of the science display screen 10.

[0025] Specifically, the locking mechanism includes a limiting frame 12 fixedly connected to both ends of the cover plate 9, and a fixed platform 13 fixedly connected to both ends of the storage box 1.

[0026] Through the above technical solution, the size design of the limiting frame 12 is to match the fixed platform 13 and the clamp plate 15, so that it can be easily locked in the arc surface between the fixed platform 13 and the clamp plate 15.

[0027] Specifically, a platform shaft 14 is fixedly inserted through the inner side of the fixed platform 13, and a clamp plate 15 is rotatably connected to the outer surface of the platform shaft 14.

[0028] Through the above technical solution, the clamp plate 15 can be easily opened and closed during the rotation along the platform shaft 14, so that the limit frame 12 can be fastened after it is placed on the arc surface of the fixed platform 13.

[0029] Specifically, an arc-shaped buckle plate 16 is fixedly connected to the outer surface of the clamp plate 15, and a limit buckle 17 is rotatably connected to the outer surface of the fixing platform 13.

[0030] Through the above technical solution, the size design of the limit buckle 17 is compatible with the arc-shaped buckle plate 16. After the two are stably fastened, the clamp plate 15 can stably hold the limit frame 12.

[0031] Working Principle: During use, the position of the science display screen 10 can be adjusted (i.e., the external display angle of the science display screen 10) via the adjustment mechanism. During this process, the end swing bar 5 can be rotated along the first damping shaft 4, cooperating with the rotation of the adjustment frame 7 on the second damping shaft 6, thereby adjusting the height of the science display screen 10 on the lower surface of the cover plate 9. Simultaneously, the angle of the science display screen 10 can be adjusted along the third damping shaft 8 until the science display screen 10 is adjusted to a suitable position. When storing, the science display screen 10 can also be stored in the storage slot 3 inside the storage box 1 via the damping shaft, end swing bar 5, and adjustment frame 7. During the process, the rubber sealing ring 11 fits tightly against the inner wall of the storage box 1, thus effectively preventing external moisture from seeping into the storage tank 3 during storage and causing damage to the science display screen 10 due to moisture. The cover plate 9 fits completely against the top of the storage box 1 and is locked in place. At this time, the limiting frame 12 is located on the arc surface of the fixed platform 13. The clamp plate 15 can be rotated along the platform axis 14 until the clamp plate 15 is tightly locked against the limiting frame 12. Finally, the limiting buckle 17 is rotated to make it stably fastened on the arc-shaped buckle plate 16, so that the clamp plate 15 is in a stable state, that is, the cover plate 9 is stably locked inside the storage box 1. Finally, after lifting the lifting rope 2, the storage box 1 can be easily lifted and carried, achieving the effect of conveniently carrying the science popularization device.

[0032] Although embodiments of this application 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 embodiments without departing from the principles and spirit of this application, the scope of which is defined by the appended claims and their equivalents.
