Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1-4, the present invention provides a technical solution: a teaching information display device comprises a device body 10, wherein the device body 10 comprises a first display board 51 and a second display board 52, the first display board 51 and the second display board 52 are connected in a sliding mode, and when the second display board 52 slides relative to the first display board 51, the first display board 51 and the second display board 52 are overlapped or partially overlapped.
The first display board 51 is provided with a cavity 512, and the second display board 52 slides in the cavity 512. A plurality of limiting plates 513 are disposed in the cavity 512, and the limiting plates 513 are disposed on two sides of the second display board 52 to limit the second display board 52 from sliding. Fastening bolts 511 are arranged at the top and the bottom of the first display plate 51, the fastening bolts 511 penetrate through the limiting rods and abut against the second display plate 52, and nuts 514 matched with the fastening bolts 511 are arranged on the first display plate 51. The up end of device body 10 is provided with projection equipment 20, projection equipment 20 includes scalable bracing piece 21, connection buckle 23 and projector 22, scalable bracing piece 21 fixed connection is at projection equipment 20's lower terminal surface, scalable bracing piece 21 through connect buckle 23 with device body 10 connects. One side of the device body 10 is hinged with a foldable extension board 40, one side of the second display board is provided with a connecting piece 521, and the second display board is rotatably connected with the foldable extension board 40 through the connecting piece 521.
The concrete during operation: by pushing the second display board 52, the second display board 52 moves towards the inside of the first display board 51 along the four limiting plates 513, namely, the upper left limiting plate, the lower left limiting plate, the upper right limiting plate and the lower right limiting plate in the cavity 512, and the second display board 52 is stored until the first display board 51 and the second display board 52 are completely overlapped; when the first display board 51 is partially overlapped with the second display board 52, the original one display board can be unfolded into two, so that the flexibility of the device is improved; the rotation and positioning of the foldable extension board 40 are realized by the connection 521 between the foldable extension board 40 and the second display board 52.
