Description

Technical Field

[0001] The utility model relates to the field of advertising light boxes, in particular to an advertising light box which is convenient to disassemble. Background Technique

[0002] Billboards generally refer to all outdoor media that convey advertising information. With the continuous development of cultural undertakings, billboards can be seen everywhere and are distributed in various locations in the city. In terms of the scale of billboards, there are not only huge billboards installed on the outer walls of buildings, but also small billboards hung on poles. As is well known, the purpose of billboards is to widely publicize, that is, to attract more attention. Therefore, with the design of billboards, advertising boxes with light sources have emerged as the times require and become a scenic line in the city. However, the doors of existing advertising light boxes are fixed by a large number of screws, and due to the large volume of the doors, it is inconvenient to disassemble and install the doors, and the applicability is low.

[0003] Existing billboards can be adsorbed on the light box through a magnetic structure. Although this solution is convenient for installation, when disassembling, a lot of force is required to pull it out manually, which is still very inconvenient in actual use. Content of the Utility Model

[0004] In order to solve the above technical problems, the utility model provides an advertising light box which is convenient to disassemble.

[0005] An advertising light box which is convenient to disassemble provided by the utility model adopts the following technical scheme:

[0006] An advertising light box which is convenient to disassemble includes a base, a light box main body and a billboard. The light box main body is arranged on the base, the billboard is detachably connected to the light box main body, a plurality of LED light strips are arranged in the light box main body, a groove is formed in the light box main body, the billboard is placed in the groove, a through groove is formed in the light box main body, a magnetic attraction assembly is arranged in the through groove, the magnetic attraction assembly includes a coil and an iron core, the coil is wound around the iron core, and the coil is externally connected with a power supply.

[0007] Optionally, a circular plastic strip is arranged in the groove, and the circular plastic strip has elasticity.

[0008] Optionally, a long groove is formed in the side surface of the light box main body, and a plurality of heat dissipation fins are arranged in the long groove.

[0009] Optionally, an anti-slip rubber pad is arranged at the bottom of the base.

[0010] Optionally, a plurality of iron sheets are arranged on the frame of the billboard.

[0011] To sum up, the utility model includes at least one of the following beneficial technical effects:

[0012] 1. When the power supply energizes the coil, the coil can be magnetized. An iron core is arranged inside the coil, which can increase the magnetism of the coil and adsorb the billboard, making the billboard firmly adsorbed in the groove of the light box body. When the billboard needs to be replaced, only the power supply needs to be cut off. At this time, the coil is not magnetized, and the billboard can be easily taken out. The purpose of setting a circular plastic strip is to prevent the billboard from suddenly sliding out of the groove after the power is cut off, playing a blocking role.

[0013] 2. Heat dissipation fins are arranged on the side wall of the light box body, which can effectively dissipate the heat generated after the coil is energized. Description of the Drawings

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0020] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.

[0021] In addition, the meaning of "several" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0022] An embodiment of the present utility model discloses an advertising light box that is easy to disassemble. Referring to Figures 1-4 , an advertising light box that is easy to disassemble includes a base 1, a light box main body 2, and an advertising board 3. The light box main body 2 is arranged on the base 1, and the advertising board 3 is detachably connected to the light box main body 2. A plurality of LED light strips 4 are arranged in the light box main body 2. A groove 5 is formed on the light box main body 2, and the advertising board 3 is placed in the groove 5. A through groove 6 is formed in the light box main body 2, and a magnetic attraction component is arranged in the through groove 6. The magnetic attraction component includes a coil 8 and an iron core. The coil 8 is wound around the iron core, and the coil 8 is externally connected to a power supply. A circular plastic strip 9 is arranged in the groove 5. The circular plastic strip 9 has elasticity. A long groove 7 is formed on the side surface of the light box main body 2, and a plurality of heat dissipation fins 10 are arranged in the long groove 7. An anti-slip rubber pad 11 is arranged at the bottom of the base 1. A plurality of iron sheets are arranged on the frame of the advertising board 3. Through this design, when the power supply energizes the coil 8, the coil 8 can be made magnetic. An iron core is arranged in the coil 8, which can increase the magnetism of the coil 8 and have an adsorption effect on the advertising board 3, so that the advertising board 3 is firmly adsorbed in the groove 5 of the light box main body 2. When the advertising board 3 needs to be replaced, only the power needs to be cut off. At this time, the coil 8 is not magnetic, and the advertising board 3 can be easily taken out. The purpose of arranging a circular plastic strip 9 is to prevent the advertising board 3 from suddenly sliding out of the groove 5 after the power is cut off, playing a blocking role;

[0023] Heat dissipation fins 10 are arranged on the side wall of the light box main body 2, which can effectively dissipate the heat generated after the coil 8 is energized.

[0024] The above are all the preferred embodiments of the present utility model, and the protection scope of the present utility model is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present utility model should be covered within the protection scope of the present utility model.
