Louver bulletin board

Abstract

The invention discloses a louver bulletin board comprising a first installation pipe, a second installation pipe opposite to the first installation pipe, blades installed between the two installationpipes, and a cutting tool which can move from the first installation pipe to the second installation pipe and can move from the second installation pipe to the first installation pipe; the blades aresequentially arranged in the axial direction of the first installation pipe or the second installation pipe, one end of each blade is rotationally connected with the first installation pipe, and the other end of each blade is rotationally connected with the second installation pipe; the cutting tool comprises a cutter, the cutter comprises an installation plate and a plurality of cutter blades installed at one end of the installation plate, and each cutter blade corresponds to a gap between two adjacent blades; the bulletin board further comprises a turnover mechanism enabling the blades to turn over by at least 90 degrees; and the plurality of blades are arranged one after the next in the axial direction of the first installation pipe to form a panel. The windward area of the bulletin board is greatly reduced, and the bulletin board is not easy to blow to deform or blow down. The cutter blades can cut a poster into poster bars affixed to the blades, thus not affecting turnover of theblades.

Description

technical field [0001] The invention belongs to the field of bulletin boards, and in particular relates to a louvered bulletin board. Background technique [0002] The independent bulletin board of the school that is not against the wall is easy to be blown and shaken when the wind is strong due to the large area of ​​the panel for pasting notices and posters. If it is blown down, it is troublesome and expensive to repair. So we thought of using the characteristics of blinds based on the school blinds, and designed the panel of the bulletin board to be composed of multiple blades, so that the blades can be turned over, thereby greatly reducing the windward area of ​​the bulletin board, so that the bulletin board is not easy to be blown by the wind fall. However, in reality, when printing and pasting the corresponding notices, posters, etc. on the above-mentioned bulletin boards, they are all printed in large format, and then cut into strips of notice strips (or poster stri...

AI Technical Summary

Problems solved by technology

However, in reality, when printing and pasting the corresponding notices, posters, etc. on the above-mentioned bulletin boards, they are all printed in large format, and then cut into strips of notice strips (or poster strips, etc.), which increases the process and makes the notices, posters, etc. Increased printing costs for posters, etc.

When pasting strips of notices and posters on the blades, the following problems were also found: on the one hand, the more the strips are, the more troublesome and troublesome it is to paste them one by one; on the other hand, the notification strips (or poster strips, etc.) Some are high on the left, some are low on the left, or high or low), so it looks irregular and awkward, and it will also affect the continuity of the content of adjacent notification bars (or poster bars, etc.), which is inconvenient to watch and read
