Description

Technical Field

[0001] This utility model relates to the field of illuminated sign technology, specifically to a splicable illuminated sign structure. Background Technology

[0002] Illuminated signs are widely used in advertising signage, commercial displays, and other scenarios. Traditional illuminated signs are mostly one-piece structures, which makes production, transportation, and installation difficult when displaying complex or large text or patterns. Furthermore, their splicing flexibility is poor, making it difficult to quickly adjust the combination to meet actual needs. Some splicable illuminated signs suffer from unstable splicing, illumination effects affected by splicing, and low installation adaptability, impacting their usability and suitability for various scenarios.

[0003] Therefore, a type of illuminated letter structure that is flexible in splicing, stable, has good lighting effect, and is easy to install is needed. Utility Model Content

[0004] (a) Technical problems to be solved.

[0005] In view of the shortcomings of the existing technology, this utility model provides a splicable illuminated character structure, which solves the problems mentioned in the background technology.

[0006] (ii) Technical solution.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a splicable illuminated character structure, including an outer frame, an illuminating mechanism, and a splicing assembly mechanism.

[0008] The mounting frame structure includes a square frame. An assembly groove is provided in the lower center of the rear end of the inner side wall of the square frame for installing related connecting parts. A protective tempered glass plate is fixedly connected to the front opening of the square frame to protect the front end of the light-emitting mechanism. Two mounting bases are symmetrically fixedly connected to the bottom of the square frame. An oblong groove is provided between the upper and lower side walls of the mounting base to facilitate fixing the mounting frame to the mounting surface using bolts or other means. The oblong groove can be adapted to different mounting hole positions within a certain range, improving installation adaptability.

[0009] The light-emitting mechanism includes a light-shielding plate fixedly installed on the front end of the inner side wall of the square frame. A letter-shaped matching groove is opened between the front and rear side walls of the light-shielding plate, and a light-transmitting letter block is fixedly installed in the letter-shaped matching groove. The light-transmitting letter block can display the desired text or pattern shape to achieve light-emitting display. A backlight module is fixedly connected to the rear end of the light-shielding plate to provide a backlight source for the light-transmitting letter block. The backlight module is fixedly installed on the inner side wall of the square frame, and a three-proof connector is set at the lower rear end of the backlight module. The bottom end of the three-proof connector is provided with a three-proof interface. The three-proof connector is fixedly installed in the mounting groove. The three-proof connector can ensure stable power supply and signal transmission of the backlight module in complex environments, improving the applicability of the illuminated letters.

[0010] The assembly mechanism consists of five L-shaped locking clips fixedly connected at equal intervals from top to bottom to one side of the rear end of a square frame. Each L-shaped locking clip has a slot between its two side walls and a first mating hole between its front and rear side walls. The assembly mechanism also includes a connecting shaft rotatably mounted on the other side of the rear end of the square frame. The other end of the connecting shaft is fixedly connected to a block with five matching slots. Each block has a second mating hole between its front and rear side walls that matches the first mating hole. A fastening bolt is fixedly connected to the center of each of the upper and lower ends of the connecting shaft. Two fixing seats are symmetrically fixedly connected to the other side of the rear end of the square frame. Each fixing seat has a through hole between its upper and lower side walls for the fastening bolts to rotate and assemble. During assembly, adjacent illuminated letter blocks are inserted into their slots. The fastening bolts pass through the first and second mating holes and mate with the through holes of the fixing seats to achieve stable assembly. The connecting shaft allows for adjustment of the assembly angle within a certain range, improving assembly flexibility.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. In this utility model, by setting up an installation frame, a light-emitting mechanism, and a splicing assembly mechanism, the installation frame provides the foundation for installation and splicing. In the light-emitting mechanism, the light-transmitting letter blocks, backlight modules, and light-shielding plates work together to ensure clear and stable light-emitting display effects. The splicing assembly mechanism uses L-shaped fitting clips, clip blocks, connecting shafts, and fastening bolts to achieve flexible and stable splicing. Different forms of illuminated letters can be combined according to requirements, solving the problems of difficult splicing and poor flexibility of traditional illuminated letters.

[0012] 2. In this utility model, the waist-shaped groove of the mounting base improves the installation adaptability, making it easy to fix on different mounting surfaces. The three-proof connector ensures that the backlight module works stably in complex environments, enhancing the applicability of illuminated signs and making them suitable for use in more scenarios such as outdoors and humid environments, thereby improving the overall practicality and promotional value.
