Description

Technical Field

[0001] The utility model relates to the field of bulletin boards, in particular to an information bulletin board. Background Art

[0002] At present, bulletin boards are widely used in teaching as traditional information dissemination carriers. They can also read newspapers, display maps, and serve as small blackboards and hanging items. They are multifunctional, stimulating students' interest in reading, expanding their horizons, and increasing utilization, thereby effectively improving teaching efficiency and enriching students' knowledge. In order to protect the internal display, existing information bulletin boards are equipped with transparent glass windows on the outside. When replacing the internal content of the bulletin board, it is necessary to open the glass windows before operating. After the glass windows are opened, they extend to the outside, which is easy to block the roadside space and increase the probability of collision damage. In addition, some bulletin boards have transparent windows on the front and back for display, so it is inconvenient to open the glass windows back and forth on both sides. Therefore, the applicant believes that it is necessary to design a bulletin board structure that is convenient for quickly and safely replacing the internal display content to solve the above problems.
