Description

Technical Field

[0001] The utility model relates to the technical field of publicity and display, in particular to an educational publicity and display device. Background Art

[0002] Security can be understood as the abbreviation of "safety precautions". According to the explanation in current Chinese dictionaries, safety means no danger, no harm and no accidents; prevention means preparation and alertness, and prevention means being prepared to deal with attacks or avoid being harmed, and alertness means prevention and protection.

[0003] In recent years, natural disasters have occurred frequently, causing irreparable losses to society and the people and leaving unforgettable shadows in people's hearts. Entering the new era, the Party and the state government have become increasingly aware of the importance of disaster prevention and mitigation safety education. To this end, governments at all levels have allocated funds to require schools and society to carry out disaster prevention and mitigation safety education and training.

[0004] The sizes of existing security education knowledge publicity and promotion display equipment are fixed. Since the content of the publicity is more comprehensive than before, it is necessary to splice the publicity display devices together to increase the display area. Generally, the two display boards need to be combined together through external objects, and the combination is also relatively cumbersome. In order to facilitate the combination of display devices, this scheme proposes an education publicity display device. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide an educational publicity display device to solve the problems raised in the background technology.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] An educational publicity and display device comprises a display board, a locking block and a limiting plate, wherein a fixed frame is arranged on the display board, a group of first grooves are opened on the display board, a second groove is opened on the display board, a group of limiting rods are arranged on the locking block, two limiting rods are matched in the holes on the fixing plate, two fixing plates are arranged on the first groove, a first compression spring is sleeved on the outer peripheral surface of the two limiting rods, one end of the first compression spring is in contact with the fixing plate, and the other end of the first compression spring is in contact with the limiting rod, the limiting plate is arranged on the second groove, a group of limiting columns is arranged on the limiting plate, one end of the two limiting columns is connected to the display board, a second compression spring is sleeved on the outer peripheral surface of the two limiting columns, one end of the second compression spring is in contact with the limiting plate, and the other end of the second compression spring is in contact with the limiting column.

[0008] Preferably, a group of support columns are provided on the display board, rectangular grooves are provided on the support columns, and limiting holes are provided on the rectangular grooves.

[0009] Preferably, the engaging block is in contact with the display plate, and the engaging block is in contact with the limiting plate.

[0010] Preferably, a support plate is further included, the support plate includes a group of vertical plates, and protruding blocks are arranged on the vertical plates.

[0011] Preferably, the vertical plate is matched on the rectangular groove, and the protruding block is matched on the limiting hole.

[0012] The utility model has the following beneficial effects:

[0013] The content to be displayed is placed on the display board. When the area to be displayed is large, the engaging block on one side of the display board is pushed outward, thereby compressing the first compression spring. At this time, the engaging block will squeeze the limiting plate, thereby squeezing the second compression spring. When the sides of the two display boards are connected, the engaging block will be engaged with the limiting plate under the action of the second compression spring, and the fixing engaging block can be thereby spliced ​​together with the two display boards, thereby increasing the display area.
