Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] Example 1

[0024] Reference Figure 1-4 A display board includes: a bottom plate 1, an outer frame 5 is fixedly connected to the top of the bottom plate 1, a mounting groove 4 is opened on one side of the outer frame 5, and slide grooves 22 are opened on the inner walls of both sides of the mounting groove 4, and sliders 24 are slidably connected to the inner walls of the slide grooves 22, and a spring 23 is fixedly connected between the bottom of the slider 24 and the bottom inner wall of the slide groove 22, and the sides of the two sliders 24 close to each other are rotatably connected to the rotating shaft 20, and the same inner frame 3 is fixedly connected between the two rotating shafts 20, and a pressing component for pressing paper is arranged inside the inner frame 3, and the pressing component includes a fixed plate 10 fixedly connected between the inner walls of both sides of the inner frame 3, and a spring 23 is fixedly connected between the inner walls of both sides of the inner frame 3. A sliding plate 9, a screw rod 12 is penetrated through the internal thread of the fixed plate 10, one end of the screw rod 12 is rotatably connected to one side of the sliding plate 9, and the other end of the screw rod 12 is fixedly connected to an operating block 11. A glass plate 2 is integrally formed on one side of the inner frame 3, and a plurality of suction cups 7 are adsorbed on the glass plate 2. One end of the suction cup 7 is fixedly connected to a connecting plate 6, and one side of the connecting plate 6 is fixedly connected to a rubber pad 8. After replacing the paper, the operating block 11 can be rotated, and the operating block 11 drives the screw rod 12 to rotate, and the screw rod 12 drives the sliding plate 9 to move horizontally, and the sliding plate 9 presses the upper side of the paper, and the position of the suction cup 7 can be adjusted at the same time, and the lower end of the paper is pressed by the connecting plate 6 and the rubber pad 8, which is convenient to use;

[0025] A transverse hole 15 is provided on one side of the outer frame 5, and a protective component for protecting the device is arranged inside the transverse hole 15. The protective component includes a protrusion 18 that slides through the inside of the transverse hole 15, and a rectangular block 17 is fixedly connected to the bottom of the protrusion 18. The same tension spring 16 is fixedly connected between one side of the rectangular block 17 and the inner wall of one side of the outer frame 5. When it is necessary to replace the displayed paper, it is necessary to first slide the protective block 13 upward from the inside of the vertical groove 14 from the rear of the outer frame 5. Since the protective block 13 fits perfectly with the vertical groove 14, it is difficult for ordinary people to find that after the protective block 13 no longer blocks the protrusion 18, the rectangular block 17 moves laterally under the tension of the tension spring 16. At this time, the rectangular block 17 drives the protrusion 18 to pass through the transverse hole 15, and then the protrusion 18 moves out from the inside of the inner frame 3, releasing the braking state of the inner frame 3.

[0026] A vertical groove 14 is provided on one side of the top of the outer frame 5 . The vertical groove 14 is communicated with the horizontal hole 15 . A protective block 13 is slidably connected to the inner wall of the vertical groove 14 . The protective block 13 cooperates with the protrusion 18 for use.

[0027] This application can be used for employment guidance, and can also be used in other fields applicable to this application.

[0028] Example 2

[0029] refer to Figure 1-4 , improved on the basis of Example 1: a display board that is easy to change content, which is used in the field of employment guidance, the inner walls on both sides of the outer frame 5 are fixedly connected with fixed blocks 25, the bottom of the fixed block 25 is fixedly connected with a clamping rod 21, and a circular hole 19 is opened inside the rotating shaft 20, and the circular hole 19 is engaged with the clamping rod 21. At this time, the inner frame 3 can be moved vertically downward, and the inner frame 3 drives the rotating shaft 20 to move vertically downward, and the rotating shaft 20 drives the slider 24 to move vertically downward and squeeze the spring 23. At the beginning, the clamping rod 21 is inside the rotating shaft 20, and the rotating shaft 20 cannot rotate and can only move downward. When the clamping rod 21 and the rotating shaft 20 are separated, the rotating shaft 20 can be rotated to adjust the inner frame 3 to a horizontal state.

[0030] In the present application, when it is necessary to replace the displayed paper, the protective block 13 needs to be slid upward from the inside of the vertical slot 14 from the rear of the outer frame 5. Since the protective block 13 fits perfectly with the vertical slot 14, it is difficult for ordinary people to find that after the protective block 13 no longer blocks the protrusion 18, the rectangular block 17 moves laterally under the tension of the tension spring 16. At this time, the rectangular block 17 drives the protrusion 18 to pass through the horizontal hole 15, and then the protrusion 18 moves out from the inside of the inner frame 3, releasing the braking state of the inner frame 3;

[0031] At this time, the inner frame 3 can be moved vertically downward, and the inner frame 3 drives the shaft 20 to move vertically downward, and the shaft 20 drives the slider 24 to move vertically downward and squeeze the spring 23. At the beginning, the clamping rod 21 is inside the shaft 20, and the shaft 20 cannot rotate and can only move downward. When the clamping rod 21 and the shaft 20 are disengaged, the shaft 20 can be rotated to adjust the inner frame 3 to a horizontal state. After the paper is replaced, the operating block 11 can be rotated, and the operating block 11 drives the screw rod 12 to rotate, and the screw rod 12 drives the sliding plate 9 to move horizontally. The sliding plate 9 presses the top of the paper. At the same time, the position of the suction cup 7 can be adjusted, and the lower end of the paper can be pressed by the connecting plate 6 and the rubber pad 8 for easy use.

[0032] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
