DETAILED DESCRIPTION

[0015] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0016] A student guidance management announcement device, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5As shown, it includes a box body 1, one side of the box body 1 is provided with an opening, and a glass window 2 is sealed and matched, one side of the glass window 2 is hinged on the box body 1, and the other side of the glass window 2 is connected to the box body 1 through a door lock, a bulletin board 3 for pasting bulletins is provided in the box body 1, a horizontal partition 4 and a vertical partition 5 are fixedly installed in the box body 1, the outer periphery of the horizontal partition 4 is fixedly connected to the inner wall of the box body 1, the bottom of the vertical partition 5 is fixedly connected to the top of the horizontal partition 4, and the top of the vertical partition 5 is fixedly connected to the inner wall of the box body 1, the spaces on the left and right sides of the vertical partition 5 are connected, and a plurality of bulletin boards 3 are respectively provided on both sides of the vertical partition 5, and the bulletin boards 3 on the same side are arranged in parallel, and the horizontal partitions 4 and the vertical partitions 5 are fixedly connected to the inner wall of the box body 1. The partition 4 is provided with an annular through groove 8 with four beveled corners, and the slide bar 7 is fixedly installed on the bulletin board 3, and the slide bar 7 is slidably installed in the annular through groove 8 and passes through the annular through groove 8 respectively. A pair of sprocket wheels 9 are rotatably installed on the front and rear sides of the box body 1 respectively, and the corresponding sprocket wheels 9 are connected by a chain 10 for transmission. A driving mechanism for driving the two pairs of sprocket wheels 9 to rotate in opposite directions is provided in the box body 1, and a plurality of spring rods 11 with the same intervals are fixedly installed on the chain 10 respectively, and the fixed end of the spring rod 11 is fixedly connected to the corresponding chain 10, and a wedge block 12 is fixedly installed on the movable end of the spring rod 11, and the wedge block 12 can be slidably contacted and matched with the slide bar 7. The present invention has a simple structure and an ingenious design, and can sequentially move the bulletin board 3 to an aligned position with the glass window 2, so that it is convenient to view the information on different bulletin boards 3 through the glass window 2, and can display more information, thereby avoiding the problem that the existing display device needs to frequently change the limited information displayed, and is more convenient to use, can meet actual needs, and is suitable for promotion.When the present invention is used, the glass window 2 is opened, and the notice board 3 is moved to the glass window 2 in sequence by the driving mechanism, and the notice to be displayed is pasted on the notice board 3, and then the glass window 2 is closed, and the sprocket wheels 9 on the front and rear sides are driven to rotate in opposite directions by the driving mechanism. The sprocket wheels 9 on the front side rotate and drive the spring rods 11 thereon to revolve forward through the chains 10. When the wedge block 12 on the spring rod 11 contacts the slide bar on the notice board 3 on the left side, a thrust is given to the slide bar 7, thereby pushing the corresponding notice board 3 to move to the right under the guidance of the annular through groove 8, until the notice board 3 is aligned with the glass window 2, and the information on the notice board 3 can be viewed through the glass window 2. When it is necessary to replace the notice board 3, the sprocket wheel 9, chain 10, and spring rod 11 are continued to be driven by the driving mechanism to move, and the wedge block 12 continues to push the notice board 3 to move. When the slide bar 7 drives the notice board 3 to slide the right part of the annular through groove 8, the notice board 3 is Unable to continue moving to the right, the spring rod 11 still moves to the right at this time, and the slide bar 7 gives a reaction force to the inclined surface of the wedge block 12, shortening the spring rod 11 until the wedge block 12 is separated from the bulletin board 3. The spring rod 11 is reset under the action of its own elastic force, and when the wedge block 12 on the other spring rod 11 contacts the slide bar 7 on the next bulletin board 3, the above process is repeated. When the next bulletin board 3 also moves to the right part of the annular through groove 8, this bulletin board 3 pushes the previous bulletin board 3 to move backward. By the same principle, driven by the driving mechanism and the rear sprocket 9 chain 10, the bulletin board 3 on the rear side of the box body 1 will move from the right side of the vertical partition board 5 to the left side of the vertical partition board 5, thereby realizing the cyclic revolution of the bulletin board 3 for cyclic display; a large number of bulletin boards 3 can display more bulletin information at the same time, and at the same time avoid the problem of removing and giving way to old bulletins when updating bulletins, so that old bulletins can be displayed for a longer time.

[0017] Specifically, if Figure 2 As shown, the notice board 3 of this embodiment has grooves 20 on both sides, and the other side of the box body 1 is also provided with an opening and is matched with the glass window 2. Notices can be pasted in the grooves 20 on the front and rear sides respectively. When the notice board 3 is driven to align with the glass window 2 on the front side, the notice on the front side of the notice board 3 can be viewed, and when the notice board 3 is driven to align with the glass window 2 on the rear side, the notice on the rear side of the notice board 3 can be viewed, so that both the front and rear sides of the notice board 3 are utilized, thereby improving the utilization rate of the device.

[0018] Specifically, Figure 1 , Figure 2As shown, the first spherical grooves 30 are respectively provided on both sides of the top of the notice board 3 described in this embodiment, and the first spherical grooves 30 are respectively provided with the first spheres 31, the first spherical grooves 30 are larger than half of the first spheres 31, and the surface of the first spheres 31 is in sliding contact with the inner wall of the first spherical grooves 30, and the inner wall of the box body 1 is provided with a slide groove 32 corresponding to the first spheres 31, and the part of the first spheres 31 located outside the first spherical grooves 30 is in sliding contact with the slide grooves 32. When the slide bar 7 drives the notice board 3 to slide along the annular through groove 8, the first spheres 31 on the notice board 3 slide in the slide grooves 32, which can prevent the notice board 3 from rotating itself when moving, thereby making its movement more stable, and at the same time, the first spheres 31 can rotate in the first spherical grooves 30, reducing the friction between the slide grooves 32.

[0019] Further, such as Figure 1 As shown, a plurality of second spherical grooves 40 are respectively provided on one side of the notice board 3 in the present embodiment, and a second sphere 41 is respectively provided in the second spherical grooves 40, and the second spherical grooves 40 are larger than half of the second sphere 41, and the surface of the second sphere 41 is in sliding contact with the inner wall of the second spherical groove 40, and the second sphere 41 is in contact with one side of the adjacent notice board 3. When a notice board 3 moves along the hypotenuse of the annular through groove 8, the second sphere 41 can convert the friction between it and the adjacent notice board 3 into rolling friction, thereby reducing the friction force when the notice board 3 moves.

[0020] Furthermore, Figure 3 As shown, the driving mechanism described in this embodiment includes a motor 50, which is fixedly installed in the housing 1, and a coaxial first bevel gear 51 is fixedly installed on the output shaft of the motor 50, and the first bevel gear 51 is rotatably installed on the housing 1. The rotating shaft of the first bevel gear 51 is rotatably connected to the inner wall of the housing 1 through a bearing, and the two sides of the first bevel gear 51 are respectively meshed and matched with second bevel gears 52, and the coaxial transmission shafts 53 are respectively fixedly installed on the second bevel gears 52, and the transmission shafts 53 are rotatably installed in the housing 1, and the transmission shafts 53 are fixedly connected to a sprocket 9 on the corresponding side, and the remaining sprockets 9 are respectively rotatably connected to the support rods through bearings, and the support rods are fixedly installed on the inner wall of the housing 1, and the transmission shafts 53 are coaxially arranged with the corresponding sprockets 9. When the motor 50 is powered on and operated, the output shaft of the motor 50 drives the first bevel gear 51 to rotate, and then through the transmission of the second bevel gear 52, the two transmission shafts 53 are driven to rotate together, and the rotation directions of the two second bevel gears 52 are opposite, so that the sprockets 9 on both sides rotate in opposite directions.

[0021] Furthermore, Figure 3As shown, one end of the transmission shaft 53 of this embodiment extends to the outside of the box body 1, and a crank 60 is fixedly installed. One end of the transmission shaft 53 is rotatably connected to the reserved hole on the box body 1 through a bearing, and the other end of the transmission shaft 53 is rotatably connected to the inner wall of the box body 1 through a seat bearing. When the motor 50 is not powered, the transmission shaft 53 can also be driven to rotate through the crank 60, realizing two driving modes of the transmission shaft 53.
