Description

Technical Field

[0001] The utility model relates to the technical field of luminous characters, in particular to a connection structure of luminous characters. Background Art

[0002] Illuminated characters are luminous signs made of a character shell, panel, and base plate, which mostly use light-emitting diodes as light sources. Illuminated characters are colorful and personalized, making the signs more humane and playing an important promotional role for enterprises, stores, and exhibitions.

[0003] Existing luminous characters are usually fixed to billboards and walls with screws. This fixing method has a relatively strong fixing effect. However, when there is a problem with the diode inside the luminous character and it needs to be repaired or replaced, the personnel need to disassemble the entire luminous character device and then take out the LED lamp for replacement. The operation is cumbersome and very inconvenient. Utility Model Content

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See also Figure 1-5, including a mounting plate 1 and a font base plate 2 fixed on the surface of the mounting plate 1, a font front cover 3, mounted on the side of the font base plate 2 away from the mounting plate 1, and the font front cover 3 and the font base plate 2 can be separated separately; a light-emitting diode 4, mounted on the bottom of the inner wall of the font base plate 2; a protrusion 5, fixed on the side wall of the font base plate 2, the position of the protrusion 5 close to the side wall of the font base plate 2 is a cylinder, the end of the cylinder away from the side wall of the font base plate 2 is a spherical block, and the diameter of the spherical block is greater than the diameter of the cylinder, so that the two ends of the cylinder of the protrusion 5 are respectively restricted; an extension plate 6, fixed on the side of the font front cover 3 close to the font base plate 2, the extension plate 6 is L-shaped, and is bent toward the inside of the font base plate 2, and the thickness of the extension plate 6 is equal to the length of the cylinder of the protrusion 5; a limiting hole 7, opened at the position of the extension plate 6 corresponding to the protrusion 5, and an oblique groove is opened on the side of the limiting hole 7 away from the extension plate 6 A through hole is provided between the inclined groove and the limiting hole 7. When the font front cover 3 and the font base plate 2 need to be assembled, the font front cover 3 can be directly aligned with the font base plate 2, so that the limiting hole 7 corresponds to the protrusion 5. By pressing the font front cover 3 toward the font base plate 2, the cylindrical part of the protrusion 5 is engaged with the limiting hole 7. The cylinder enters the limiting hole 7 through the guidance of the inclined groove and the through hole, so that the extension plate 6 limits the cylinder, thereby achieving the purpose of fixing the font base plate 2 and the font front cover 3 to each other, and quickly completing the assembly of the font base plate 2 and the font front cover 3; the movable rod 11 is installed on one side of the font front cover 3, and the font front cover 3 is pulled away from the font base plate 2 by the movable rod 11. Since the font base plate 2 is fixed to the mounting plate 1, the font front cover 3 can be tilted by the movable rod 11, thereby reducing the use of additional tools when disassembling the font front cover 3. The font front cover 3 is provided with an movable hole 10 at the position corresponding to the movable rod 11. The movable rod 11 is a truncated cone, one end of which is larger than the other end. The larger end is arranged outside the font front cover 3, and a pull ring is fixed to the end. When the movable rod 11 is inserted into the font front cover 3, the larger end will be stuck in the movable hole 10 to limit the movement of the movable hole 10. When the font front cover 3 needs to be disassembled, the movable rod 11 is pulled toward the outside of the font front cover 3 through the pull ring to extend the movable rod 11 out of the font front cover 3. When the smaller end of the movable rod 11 is attached to the inner wall of the font front cover 3, the movable rod 11 uses the movable hole 10 as a fulcrum to pry the font front cover 3 away from the font bottom plate 2, thereby reducing the use of tools and improving the convenience of disassembly and assembly of the font front cover 3.

[0027] The light emitting diode 4 is fixed with a limiting groove 8 on both sides. A light-transmitting plate 9 is installed inside the limiting groove 8. The light emitted by the light emitting diode 4 is uniformly distributed through the light-transmitting plate 9, so that the light source of the luminous characters is softer and more stable. When the light-transmitting plate 9 and the limiting groove 8 are assembled, the two ends of the light-transmitting plate 9 are moved inward through the plastic deformation ability of the light-transmitting plate 9, so that the light-transmitting plate 9 enters the limiting groove 8. After the light-transmitting plate 9 is released, the light-transmitting plate 9 automatically recovers, so that the legs at both ends of the light-transmitting plate 9 are stuck in the limiting groove 8, and the position of the light-transmitting plate 9 is limited.

[0028] Working principle: when fixing the luminous characters, fix the character base plate 2 directly to the surface of the mounting plate 1, arrange the light-emitting diode 4 in the middle of the limiting groove 8 inside the character base plate 2, assemble the light-transmitting plate 9 with the limiting groove 8, so that after the light-emitting diode 4 emits light, the light can be evenly distributed through the light-transmitting plate 9. After the limiting groove 8 is installed, align the character front cover 3 with the character base plate 2, so that the limiting hole 7 inside the character front cover 3 corresponds to the protrusion 5, and press the character front cover 3 toward the character base plate 2 so that the protrusion 5 is stuck in the limiting hole 7, so that the character front cover 3 and the character base plate 2 are connected. When the light-emitting diode 4 has a problem and needs to be replaced, there is no need to remove the entire luminous character from the surface of the mounting plate 1. By pulling The ring pulls the movable rod 11 out from the inside of the font front cover 3, and uses the movable hole 10 as a fulcrum to pull the font front cover 3 in the direction away from the font base plate 2, so that the protrusion 5 breaks free from the restriction of the limiting hole 7, thereby separating the font front cover 3 from the font base plate 2. After the font front cover 3 is separated from the font base plate 2, the light-emitting diode 4 in the font base plate 2 is exposed, which is convenient for repairing the light-emitting diode 4. When the light-emitting diode 4 is replaced, the font front cover 3 is aligned with the font base plate 2, and the font front cover 3 is pressed hard in the direction of the font base plate 2, so that the font front cover 3 is connected and fixed to the font base plate 2 again. After the font front cover 3 is connected to the font base plate 2, the movable rod 11 is pushed back into the font front cover 3 to improve the aesthetics of the appearance of the luminous characters.
