Embodiment Construction

[0042] This embodiment includes a bracket 5, an upper main shaft part, a lower main shaft part, a power shaft part, a beam part and a guide part.

[0043] like image 3 and Figure 4 As shown, the support 5 is a double-layer square frame structure, and the two-layer frames of the support 5 are parallel to each other and the orthographic projection coincides; there are five pairs of parallel reinforcing ribs on both sides of the frame, through which the two-layer parallel frame Solid connection; one pair of reinforcing ribs is located at the lower end of the frame, and the remaining four pairs of reinforcing ribs are distributed on the upper part of the frame. From top to bottom, the upper main shaft installation beam 19, the cross beam installation beam 27, the lower main shaft installation beam 26, and the power shaft installation beam are sequentially formed. 22 and the recovery box installation beam 42, and the vertical distance between each adjacent installation beam must...

Abstract

The invention provides a notice board with recoverable notice paper. Two ends of an upper main shaft (17) are arranged on an upper-main-shaft installation beam; two ends of a crossbeam (36) are fixed on a crossbeam installation beam (27); two ends of a lower main shaft (13) are arranged on a lower-main-shaft installation beam (26); two ends of a power shaft (6) are fixed on a power-shaft installation beam (22); two ends of a turning-plate supporting shaft (33) penetrate into a mounting hole (32) of the lower-main-shaft installation beam (26); the outer circumference of a roller of an upper main shaft component and a lower main shaft component is sleeved with a friction tape (3); a recovering box (29) is positioned on a recovering-box installation beam (42); and the front of a bracket is provided with glass clinging to the friction tape. When the notice board is in use, power is input through a handle, and then the friction tape can drive notice paper to move upwards; and after the handle is no longer turned, the notice paper can be clamped between the glass and the friction tape, thus the notice board is convenient to use. As the recovering box is arranged on the bracket, managers can open the recovering box regularly to recover the notice paper.

Description

1. Technical field [0001] The invention relates to a bulletin board, in particular to a bulletin board with recyclable bulletin paper. 2. Background technology [0002] At present, there are many styles of bulletin boards widely used in most communities, schools, hospitals, supermarkets and other places, and the structures are not the same, but they are basically made of iron plates, and the bulletin boards are directly pasted on the box. The main problem is that glue and paste are required to paste the notice paper, which is inconvenient to use; the notice paper is easy to be blown off and wet in wind and rain, which affects the display effect; some users paste and cover other people's notices at will, which has a bad impact; For public service announcements and official announcements, there is no effective posting location and posting time; cleaning up is time-consuming and laborious, and causes serious damage to the bulletin board box, and the cleaned paper is seriously d...
