[0002] Propaganda education is an educational tool used for publicity and display. It is an effective means for schools, organizations or enterprises to carry out self-publicity. It is often set up in public places such as schools, communities and exhibition halls. It generally uses stainless steel as the frame and polycarbonate as the display panel, and the panel can replace the publicity picture. It can perfectly integrate into the environment, play a publicity role, and also play a decorative role. Since today's society is an information age, the channels for the public to obtain information are varied, and the publicity columns set up along the road make it impossible for people to avoid them, so they read passively. Therefore, the role of publicity columns cannot be ignored.

[0003] At present, during the use of the publicity column, different contents are mostly displayed to people by pasting different drawings on the display board of the publicity column, and in order to prevent the drawings from being damaged, the display board is mostly enclosed in the publicity column frame with glass. However, when posting and replacing drawings, it is often necessary to push or flip the glass door, and the operation is relatively limited. It is difficult to easily and completely expose the display board, which makes it inconvenient to replace the drawing content and affects the use effect. Utility Model Content

[0004] The purpose of the utility model is to provide a publicity column, which is provided with two U-shaped frames symmetrically plugged on both sides of a publicity board, and a display board is arranged in the U-shaped frame.

[0026] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0027] The utility model provides Figure 1-Figure 4 A publicity board as shown includes:

[0028] A publicity board 1, wherein a cavity 7 is formed inside the publicity board 1, and a transparent window 2 facing the cavity 7 is formed on a side wall of the publicity board 1, and U-shaped frames 8 are symmetrically embedded at both ends of the cavity 7, and a display board 9 is fixed inside the U-shaped frame 8;

[0029] Supports 11 are symmetrically fixed at both ends of the top of the publicity board 1, and a shielding plate 6 is connected between the tops of the two support posts 11. The shielding plate 6 can shield and protect the top of the publicity board 1.

[0030] The two ends of the bottom of the propaganda board 1 are symmetrically fixed with legs 3, and the bottom ends of the two legs 3 are connected with a base 4; the four ends of the bottom of the base 4 are all provided with universal wheels 5. The device can be supported and fixed by the legs 3 and the base 4, and the universal wheels 5 are used to facilitate the movement of the device.

[0031] The positioning mechanism includes a cavity 12 symmetrically opened at both ends of the U-shaped frame 8, a first spring 13 is arranged inside the cavity 12, movable plates 14 are symmetrically fixed at both ends of the first spring 13, and the two movable plates 14 are connected with positioning columns 15 relative to one end of the first spring 13. Positioning grooves 16 matching the positioning columns 15 are opened on the four ends of both sides of the propaganda board 1.

[0032] The side wall of the display board 9 is provided with a pasting area. The pasting area is convenient for pasting drawings.

[0033] The display board 9 is arranged on the inner side of the U-shaped frame 8. When in use, two symmetrical U-shaped frames 8 can be directly inserted into the two sides of the propaganda board 1, so that the U-shaped frames 8 slide in the cavity 12, and then the two U-shaped frames 8 are close to each other, and the two display boards 9 are merged together. Before the end of the U-shaped frame 8 is fully inserted into the cavity 12, by pressing the two positioning columns 15 at the same time, the positioning columns 15 can drive the movable plate 14 to move and squeeze the first spring 13, and then the positioning columns 15 are retracted into the cavity 12. When the U-shaped frame 8 is fully inserted into the cavity 12, the first spring 13 rebounds and the positioning columns 15 are reset and popped out and plugged into the positioning groove 16, so that the U-shaped frame 8 can be fastened, and finally the display board 9 is quickly installed;

[0034] When it is necessary to replace the drawing content on the display board 9, the positioning columns 15 protruding at both ends of the publicity board 1 are pressed to make the positioning columns 15 withdraw from the positioning grooves 16, thereby releasing the fixation, and then the U-shaped frame 8 is pulled outward to completely expose the display board 9. The operation is simple and fast, and the drawing is easy to replace, which greatly improves the use effect of the device.

[0035] The utility model provides Figure 5 and Figure 6 In the billboard shown, a support plate 17 is fixed in the middle of the inner top side of the cavity 7, slots 10 are symmetrically provided at both ends of the support plate 17, plug blocks 18 matching the slots 10 are fixed at one end of two U-shaped frames 8, a second spring 20 is connected to one end of the slot 10, and a baffle 19 facing the plug block 18 is fixed at one end of the second spring 20.

[0036] When the two U-shaped frames 8 are symmetrically inserted into the propaganda board 1, the plug block 18 at one end of the U-shaped frame 8 can be inserted into the slot 10 on the support plate 17 and squeeze the baffle 19, so that the baffle 19 squeezes the second spring 20. At this time, the second spring 20 maintains an elastic force storage state. Once the U-shaped frame 8 is released, under the elastic action of the second spring 20, the baffle 19 can apply a thrust to the plug block 18, so that the plug block 18 drives the U-shaped frame 8 to move, and then the end of the U-shaped frame 8 can be stretched out of the cavity 12 by force, so that it is more convenient to pull the U-shaped frame 8 out of the propaganda board 1, saving time and effort, and further improving the use effect.

[0037] The four ends of the baffle plate 19 and the movable plate 14 are all provided with arc chamfers. The arc chamfers can reduce the sliding resistance.

[0038] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
