DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] To solve the technical problem of how to flip the notice board, please refer to Figure 1-Figure 2 , this embodiment provides the following technical solutions:

[0021] A notice board for municipal buildings comprises a bracket 1 and a canopy 2 installed on the top of the bracket 1, a fixing frame 4 is movably installed on the lower end of the canopy 2 through a rotating shaft 3, and a notice board 5 is connected to the fixing frame 4 through bolts.

[0022] The notice board 5 includes a first board surface 51 , and side wing plates 511 are welded on the left and right sides of the first board surface 51 . Positioning bolts 512 are threadedly connected to the side wing plates 511 . Bolt holes 11 matching the positioning bolts 512 are opened on the inner wall of the bracket 1 .

[0023] Specifically, when the notice board 5 is to be flipped, the positioning bolt 512 is rotated or loosened so that it no longer fits tightly with the bolt hole 11 on the inner wall of the bracket 1, thereby releasing the fixing constraint on the notice board 5. At this time, the notice board 5 can be flipped 180° around the rotating shaft 3, so that the first board surface 51 is flipped to the other side to achieve double-sided display. After flipping to the desired position, the positioning bolt 512 on the side wing plate 511 is tightened again to make it fit again with the bolt hole 11 on the inner wall of the bracket 1, ensuring that the notice board 5 is stably fixed in the new position.

[0024] To solve the technical problem of how to expand the notice board, please refer to Figure 3-Figure 4 , this embodiment provides the following technical solutions:

[0025] The second plate surface 52 is slidably disposed inside the first plate surface 51 . The bottom of the second plate surface 52 passes through the first plate surface 51 and extends outside the first plate surface 51 . A groove 522 is formed at one end of the second plate surface 52 outside the first plate surface 51 .

[0026] A limiting plate 513 is welded to the bottom of the first plate surface 51, and a latch 514 is detachably connected to the limiting plate 513. A limiting hole 521 adapted to the latch 514 is provided on the second plate surface 52. Slide blocks 523 are welded to the left and right sides of the second plate surface 52. A sliding groove 515 slidably connected to the slide block 523 is provided in the first plate surface 51.

[0027] Specifically, in the initial state, the second panel surface 52 is located inside the first panel surface 51. At this time, the pin 514 on the limiting plate 513 is inserted into the limiting hole 521 on the second panel surface 52. When expansion is required, the pin 514 is pulled out so that it no longer cooperates with the limiting hole 521, thereby releasing the fixed constraint on the second panel surface 52. The second panel surface 52 can be easily pulled through the pull groove 522 to slide out of the first panel surface 51 and extend to the outside to increase the display area of ​​the notice board 5. At this time, the slider 523 slides in the slide groove 515 until the slider 523 slides to the bottom of the slide groove 515 and is limited. The second panel surface 52 cannot continue to slide, and the expansion of the notice board 5 is completed.

[0028] Working principle: In the initial state of the notice board for municipal buildings, the second panel surface 52 is located inside the first panel surface 51. At this time, the pin 514 is inserted into the limiting hole 521. When expansion is required, the pin 514 is pulled out so that it no longer cooperates with the limiting hole 521, thereby releasing the fixed constraint on the second panel surface 52. The second panel surface 52 can be easily pulled through the pull groove 522 to slide out of the first panel surface 51 and extend to the outside to increase the display area of ​​the notice board 5. At this time, the slider 523 slides in the slide groove 515 until the slider 523 slides to the bottom of the slide groove 515 and is limited. The second panel surface 52 cannot continue to slide, and the expansion of the notice board 5 is completed.

[0029] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
