[0028] In order to further understand the characteristics, technical means and specific purposes and functions achieved by the utility model, the utility model will be further described in detail below in combination with the drawings and specific embodiments.

[0029] Reference Figure 1 And Figure 2 : An advertisement lamp box convenient for loading and unloading advertising paper, the advertisement lamp box comprises a box body 1, a moving frame 2 and a clamping assembly 3, one side of the box body 1 is horizontally provided with the moving frame 2 which can reciprocate along the length or width direction of the box body 1, opposite ends of the moving frame 2 respectively extend into opposite sides of the box body 1, and the moving frame 2 is provided with a clamping frame 201, and the clamping assembly 3 is arranged on the clamping frame 201 at the opposite ends of the moving frame 2 respectively; wherein the clamping assembly 3 comprises a magnetic switch assembly 301, an elastic member 302 and a metal pressing block 303, the magnetic switch assembly 301 is arranged on one inner side of the clamping frame 201, the metal pressing block 303 is telescopically arranged on one inner side of the clamping frame 201 opposite to the magnetic switch assembly 301 through the elastic member 302, and the magnetic switch assembly 301 can control a magnetic switch to control the metal pressing block 303 to press or release the advertising paper.

[0030] When the application is loaded with an advertising paper, the moving frame 2 is moved to the loading port of the box 1, and then the two corners of the same side of the advertising paper are respectively inserted between the magnetic switch assembly 301 and the metal pressing block 303. At this time, the magnetic switch assembly 301 is started to generate a magnetic force, and at this time, the metal pressing block 303 will stretch the elastic member 302 to be close to the magnetic switch assembly 301, so as to clamp the opposite corners of the advertising paper. Finally, the user holds the advertising paper with one hand and moves the moving frame 2 to the other side of the box 1 with the other hand, so as to realize the loading of the advertising paper. The loading method can fully open the advertising paper and will not cause wrinkles. The magnetic switch assembly 301 can select an electromagnetic coil to generate a magnetic force, or can change the magnetic field distribution by changing the layout of the magnet.

[0031] Referring to Figure 4 and Figure 5 : The magnetic switch assembly 301 comprises a first metal plate 30101, a first magnet 30102, a rotating shell 30103, a second metal plate 30104, and a second magnet 30105. The rotating shell 30103 is rotatably arranged on the side of the clamping frame 201 away from the metal pressing block 303. The first magnet 30102 is fixed with the first metal plate 30101 on opposite sides, and is fixedly arranged on the side of the rotating shell 30103 close to the metal pressing block 303. The second magnet 30105 is provided with the second metal plate 30104 on opposite sides, and is fixed in the rotating shell 30103. The magnetic field strength of the second magnet 30105 is greater than that of the first magnet 30102.

[0032] The application changes the magnetic field distribution of the second magnet 30105 by rotating the rotating shell 30103, so as to cause the magnetic poles of the first magnet 30102 and the second magnet 30105 to be the same or opposite. When the magnetic poles are opposite, the magnetic field will form a closed circuit through the first metal plate 30101 and the second metal plate 30104, which will not have magnetism. When the magnetic poles are the same, the magnetic field distribution will conduct along the first metal plate 30101 and the second metal plate 30104 to the outside of the first magnet 30102, which will have magnetism. When the rotating shell 30103 drives the second magnet 30105 to rotate more than a certain angle, the attraction or repulsion between the first magnet 30102 and the second magnet 30105 will automatically adjust the magnetic field distribution, without the need for additional limiting of the rotating shell 30103.

[0033] Referring to Figures 4-6 : A rotating knob 30106 is coaxially arranged on the upper end of the rotating shell 30103. The box 1 is provided with a strip-shaped groove 101 on opposite sides, which is matched with the rotating knob 30106.

[0034] The application controls the rotation of the rotating shell 30103 by rotating the rotating knob 30106; the rotating shell 30103 and the rotating knob can reciprocate with the moving frame 2 without interference by setting the strip-shaped slot 101.

[0035] Referring to Figure 5 : The rotating knob 30106 is provided with anti-slip lines 3010601 around the periphery.

[0036] The application sets the anti-slip lines 3010601 to facilitate the user to rotate the rotating knob 30106.

[0037] Referring to Figure 2 and Figure 7 : The moving frame 2 is provided with a limiting slide block 203, and the box 1 is provided with a limiting slide rail 102 matched with the limiting slide block 203.

[0038] The moving frame 2 is assembled in the limiting slide rail 102 through the limiting slide block 203, so that the moving frame 2 can stably reciprocate.

[0039] Referring to Figure 2 and Figure 7 : The moving frame 2 is provided with a moving handle 202 for the user to hold.

[0040] The user can hold the moving handle 202 to move the moving frame 2, improving the convenience.

[0041] The box 1 is provided with a lamp strip for illuminating the advertising paper on the inner side of the opposite two sides.

[0042] The advertising paper has light transmission, and the design can make the advertising paper emit light to improve the publicity effect; the method is prior art, and the figure is not drawn.

[0043] Referring to Figure 6 : The box 1 is provided with a groove 103 for conveniently taking out the advertising paper.

[0044] When the advertising paper needs to be taken out, the magnetic force is removed through the magnetic switch assembly 301, and the advertising paper is pinched on one side through the groove 103, so that the advertising paper is taken out.

[0045] The device provided by the utility model realizes the loading of the advertising paper, and the loading method can fully open the advertising paper, and the problem of wrinkles does not exist; the magnetic switch assembly 301 can select the electromagnetic coil to generate the magnetic force, and the method of changing the magnet layout to change the magnetic field distribution can also be used.
