Description

Technical Field

[0001] The utility model relates to the field of LED luminous characters, in particular to a novel LED advertising luminous character. Background Art

[0002] Luminous characters have built-in light sources (such as LED lights or plasma) that can emit light with high brightness and color reproduction capabilities, and have good visual impact. They are widely used in billboards, display stands, and road signs to improve advertising effects and brand image.

[0003] The light source of the luminous characters is built-in. When the light source fails or maintenance is required on the inside of the luminous characters, the luminous characters are not easy to disassemble, which may easily lead to damage to the luminous characters. The same technical problem is also raised in the background technology of an easy-to-maintain LED advertising luminous character with application number CN202222547360.6. The purpose of the utility model is to improve the existing luminous character structure to solve the above problem. Utility Model Content

[0021] Example

[0022] See also Figure 1-4 The utility model provides a novel LED advertising luminous character, comprising a character lampshade 1, a mounting plate 2 and an elastic connection mechanism, wherein an annular groove 201 matching the shape of the character lampshade 1 is formed on the mounting plate 2, a sealing sheet 202 is arranged in the annular groove 201, and the sealing sheet 202 is arranged along the circumference of the annular groove 201 and can fit with the bottom end of the character lampshade 1, and the sealing sheets 202 are arranged in pairs and located at the inner and outer sides of the character lampshade 1, and a rubber ring 204 is arranged in the annular groove 201, and the sealing sheets 202 located at the inner and outer sides of the bottom end of the character lampshade 1 are connected to the rubber ring 204, and the sealing sheet 202 and the bottom end of the character lampshade 1 attract each other, and magnetic blocks 203 are installed at the bottom end of the character lampshade 1 and the sealing sheet 202, and the magnetic blocks 203 attract each other to realize the mutual attraction between the sealing sheet 202 and the character lampshade 1, and the inner and outer sides of the bottom end of the character lampshade 1 are concave to form a recess 101 for accommodating the sealing sheet 202, and the elastic connection mechanism and the light source are installed between the character lampshade 1 and the mounting plate, The thickness of the top of the font lampshade 1 is greater than that of the rest of the font lampshade 1. The elastic connection mechanism connects the font lampshade 1 and the mounting plate 2. The elastic connection mechanism includes a first connection column 301, a second connection column 302 and a tension spring 303. The first connection column 301 is arranged in the font lampshade 1, and the second connection column 302 is located on the mounting plate 2. The first connection column 301 and the second connection column 302 are correspondingly connected in position and can be detachably connected. The tension spring 303 is installed on the first connection column 301 to replace the middle part of the first connection column 301. A limit block 304 is horizontally arranged on the second connection column 302 to form a moving pair with the second connection column 302. A reset spring 305 is arranged in the second connection column 302. The reset spring 305 is connected to the end of the limit block 304 to drive the limit block 304 to reset. A limit groove 306 matching the limit block 304 is arranged on the first connection column 301. The limit block 304 cooperates with the limit groove 306 to realize the detachable connection between the first connection column 301 and the second connection column 302.

[0023] The magnet block 203 refers to a block component made of magnet or mainly made of magnet. The specific composition and working principle of the magnet are known to those skilled in the art, so no further explanation will be given.

[0024] The font lampshade 1 refers to a lampshade-shaped component made in the style of a font, which is made of a light-transmitting material. When the light source emits light through the font lampshade 1, the light-emitting process of the luminous characters is realized.

[0025] The sealing sheet 202 refers to a sheet-like component that performs a sealing function. In a specific implementation, the sealing sheet 202 and the rubber ring 204 can both be made of elastic materials. The integrated structure has good connection strength and is not prone to leakage.

[0026] Working principle: Fix the mounting plate 2 on the billboard, the light source emits light in the space formed by the font lampshade 1 and the mounting plate 2, and the light passes through the font lampshade 1 to complete the lighting of the luminous characters. When the operator needs to maintain or clean the inside of the luminous characters, the operator pinches the top of the font lampshade 1 and pulls it outwards. At this time, the tension spring 303 is stretched, and the operator squeezes the limit block 304 to leave the limit groove 306, and the first connecting column 301 is separated from the second connecting column 302. After the font lampshade 1 and the mounting plate 2 are separated, the operator can easily maintain and clean the luminous characters.

[0027] When the maintenance and cleaning of the luminous characters are completed, the operator aligns the second connecting column 302 and the first connecting column 301 and inserts them. At this time, the return spring 305 is compressed and the limit block 304 is stuck in the limit groove 306 to prevent the font lampshade 1 from falling off the mounting plate 2, thus completing the connection between the font lampshade 1 and the mounting plate 2.

[0028] When the bottom end of the font lampshade 1 is connected to the annular groove 201, the rubber ring 204 is squeezed by the font lampshade 1 to produce elastic deformation and fully mesh with the font lampshade 1. At the same time, due to the mutual attraction between the magnet blocks 203, the sealing sheets 202 located on the inner and outer sides of the font lampshade 1 in the annular groove 201 will be tightly attached to the two sides of the font lampshade 1. The cooperation between the sealing sheet 202 and the rubber ring 204 can improve the bonding between the font lampshade 1 and the mounting plate 2, and prevent water vapor and dust from passing through the annular groove 201.

[0029] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
