Description

Technical Field

[0001] The utility model relates to the field of advertising, in particular to a waterproof luminous advertising word. Background Art

[0002] A luminous character is a luminous sign made of a letter shell, a panel, and a bottom plate with LED as the light source, and is commonly used in scenes such as door heads, companies, and cultural walls. The luminous character combines modern electronic technology and traditional sign-making technology. Utilizing the high brightness and long life characteristics of LED lights, combined with letter shells and panels of various materials, a variety of luminous character products are formed, with a strong visual impact and the ability to attract customers' attention.

[0003] The letter shell and the bottom plate of the luminous character are often adhesively connected through glass glue. However, in the outdoor environment, due to factors such as exposure to sunlight and rain erosion, the glass glue is prone to cracking, resulting in a decrease in the waterproof performance of the luminous character. Moisture entering the interior of the luminous character not only affects the lighting effect but may also cause a short circuit. The purpose of the present utility model is to improve the existing structure of the luminous character to improve the waterproof performance and solve the above technical problems. Summary of the Utility Model

[0004] The purpose of the present utility model is to provide a waterproof luminous advertising word to solve the problems mentioned in the background art.

[0005] To achieve the above purpose, the present utility model provides the following technical solutions: including a bottom plate, a letter shell, and an annular liquid sac. A light source is installed on the bottom plate. A continuous first folded edge is circumferentially arranged on the front surface of the bottom plate, and a first bending portion is formed on the first folded edge. The letter shell is made of a light guide plate. A continuous second folded edge is circumferentially arranged on the back surface of the letter shell, and a second bending portion that can abut against the first bending portion is formed on the second folded edge. The gap between the first bending portion and the second bending portion is a glue injection groove for injecting glue. The annular liquid sac is composed of a light guide film and filled with a transparent liquid. The front end of the annular liquid sac is connected to the letter shell. The annular liquid sac covers the glue injection groove and the rear end of the annular liquid sac attracts the bottom plate.

[0006] To optimize the above technical solution, a further measure is taken: the first folded edge and the second folded edge are transparent, ensuring that the light generated by the light source can pass through the first folded edge and the second folded edge and irradiate on the annular liquid sac to make the annular liquid sac emit light.

[0007] As a further improvement to the above technical solution: an annular groove for placing a rubber ring is opened on the contact surface between the first bending portion and the second bending portion. Technicians can place a rubber ring in the annular groove to improve the waterproof performance of the first folded edge and the second folded edge.

[0008] As a further improvement of the technical solution: a metal ring is placed inside the annular liquid sac, and a magnet block is embedded on the bottom plate. The magnet block and the metal ring attract each other to realize the mutual attraction between the annular liquid sac and the bottom plate.

[0009] From the above description of the structure of the present invention, compared with the prior art, the present invention has the following advantages:

[0010] A waterproof and luminous advertising word provided by the present invention can improve the weather resistance of the glass glue by arranging an annular liquid sac to surround the glue injection groove, avoid the glass glue from cracking, and prevent water vapor from penetrating into the advertising word through the crack of the glass glue, which affects the luminous effect and causes short circuit. In addition, when the annular liquid sac is blown by the air flow, the surface fluctuation can produce a rippling light effect, which helps to improve the display effect of the advertising word.

[0020] Embodiment

[0021] Please refer to Figure 1-6 , the present invention provides a waterproof and luminous advertising word, including a bottom plate 1, a word shell 2 and an annular liquid sac 3. An LED light strip is installed on the bottom plate 1 as a light source 101. A continuous first folding edge 102 is circumferentially arranged on the front surface of the bottom plate 1, and a first bending part 103 is formed on the first folding edge 102.

[0022] The word shell 2 is made of a light guide plate. A continuous second folding edge 201 is circumferentially arranged on the back surface of the word shell 2, and a second bending part 202 that can abut against the first bending part 103 is formed on the second folding edge 201. The first folding edge 102 and the second folding edge 201 are transparent. The gap between the first bending part 103 and the second bending part 202 is a glue injection groove 203 for injecting glue. An annular groove 104 for placing a rubber ring is provided on the contact surface of the first bending part 103 and the second bending part 202.

[0023] The annular liquid sac 3 is composed of a light guide film and filled with a transparent liquid. The front end of the annular liquid sac 3 is connected to the word shell 2. The annular liquid sac 3 covers the glue injection groove 203 and the rear end of the annular liquid sac 3 is attracted to the bottom plate 1. A metal ring 301 is placed in the annular liquid sac 3, and a magnet block 105 is embedded in the bottom plate 1. The magnet block 105 and the metal ring 301 attract each other to realize the mutual attraction between the annular liquid sac 3 and the bottom plate 1.

[0024] Working principle: The bottom plate 1 is fixed to the installation interface and the light source 101 is connected to the power supply. Align the second folding edge 201 of the word shell 2 with the first folding edge 102 on the bottom plate 1 so that the first bending part 103 abuts against the second bending part 202. Then, the installer injects glass glue into the glue injection groove 203 formed by the first bending part 103 and the second bending part 202. After the glass glue solidifies, the combination of the word shell 2 and the bottom plate 1 can be completed. Then, the technician pulls the annular liquid sac 3 connected to the word shell 2 to make the metal ring 301 in the annular liquid sac 3 attract the magnet block 105. The mutual attraction between the metal ring 301 and the magnet ring is used to ensure the tight fit between the first bending part 103 and the second bending part 202, which can improve the bonding property between the shell and the bottom plate 1.

[0025] The surface of the sealant groove 203 is covered by the annular liquid sac 3. Therefore, the sealant filled in the sealant groove 203 is isolated from the external environment, which helps to improve the weather resistance of the sealant and prevent the sealant from cracking due to factors such as exposure to the sun and rain erosion. In addition, the light emitted by the light source 101 can pass through the transparent first folded edge 102 and the second folded edge 201 and irradiate on the annular liquid sac 3 to make the annular liquid sac 3 emit light. When blown by the air flow, the surface of the annular liquid sac 3 will fluctuate, thus forming a rippling light effect, which can improve the display effect of the advertising characters.

[0026] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
