Description

Technical Field

[0001] This utility model relates to the field of connecting the front and rear parts of illuminated characters, specifically a novel illuminated character structure. Background Technology

[0002] Illuminated letters are a type of advertising signage product that uses LED lights as the light source. Resin illuminated letters consist of two parts: the letter shell and the light source. The outer shell is made of liquid polymer resin material and cast in one piece. After casting, the two parts of the outer shell are connected to form the letter shell.

[0003] In existing technologies, the two parts of the outer shell are usually connected by protruding points. This type of connection has obvious connection points that protrude from the surface of the outer shell. As a commercial illuminated letter (not a signboard illuminated letter), the connection points are not aesthetically pleasing and have low market acceptance. Utility Model Content

[0004] The purpose of this utility model is to provide a novel illuminated character structure in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a novel illuminated character structure, comprising an illuminated character composed of a front shell and a rear shell, wherein the front shell and the rear shell are connected by a connecting mechanism, and a sealing ring is installed on the mating end face of the front shell and the rear shell, a light strip is installed on the back end of the inner wall of the rear shell, and the back end of the rear shell is covered with reflective aluminum foil.

[0006] As a further embodiment of this utility model: the connecting mechanism includes a positioning rod integrally formed on the inner wall end face of the front housing and extending outward, and the inner wall of the positioning rod is formed with internal threads.

[0007] As a further improvement of this utility model, the connecting mechanism also includes a positioning hole opened on the back end of the rear housing, and the vertical cross section of the positioning hole is a "convex" shaped structure tilted at ninety degrees.

[0008] As a further embodiment of this utility model: the connecting mechanism further includes a locking bolt located at the back end of the rear housing, passing through the positioning hole and extending to the inner wall of the positioning rod. The locking bolt has a hexagonal hole at one end located outside the rear housing, and the outer wall of the locking bolt is formed with an external thread that engages with the internal thread.

[0009] As a further improvement of this utility model: the inner diameter of the narrow part of the positioning hole is equal to the outer diameter of the positioning rod, and the inner diameter of the wide part of the positioning hole is equal to the outer diameter of the end of the hexagonal hole.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] 1. By setting up a connecting mechanism, after the front and rear shells are connected, there are no obvious protruding connection points when the installation is completed. The connection position is effectively hidden, thereby improving the external aesthetics of the illuminated letter and meeting the needs of buyers. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figures 1-3 In this embodiment of the utility model, a novel illuminated character structure includes an illuminated character composed of a front shell 1 and a rear shell 2. The front shell 1 and the rear shell 2 are connected by a connecting mechanism, and a sealing ring is installed on the mating end face of the front shell 1 and the rear shell 2. A light strip is installed on the back end of the inner wall of the rear shell 2, and the back end of the rear shell 2 is covered with reflective aluminum foil.

[0018] In this embodiment: First, when assembling the front housing 1 and the rear housing 2, the open ends of the front housing 1 and the rear housing 2 are joined together. At this time, the connecting mechanisms distributed on the front housing 1 and the rear housing 2 are joined together to achieve effective alignment of the front housing 1 and the rear housing 2. Then, the connecting mechanisms are tightened to complete the assembly of the front housing 1 and the rear housing 2. After the connecting mechanisms are assembled, there is no protruding area when viewed from the outside, so it can achieve a better "invisible" connection effect and is more aesthetically pleasing.

[0019] Please refer to this carefully. Figure 3The connecting mechanism includes a positioning rod 3 integrally formed on the inner wall end face of the front housing 1 and extending outward. The inner wall of the positioning rod 3 is formed with an internal thread 4. The connecting mechanism also includes a positioning hole 5 opened on the back end of the rear housing 2. The vertical cross section of the positioning hole 5 is a "convex" shaped structure tilted at ninety degrees. The connecting mechanism also includes a locking bolt 6 located at the back end of the rear housing 2, passing through the positioning hole 5 and extending to the inner wall of the positioning rod 3. The locking bolt 6 has a hexagonal hole 8 at one end located outside the rear housing 2. The outer wall of the locking bolt 6 is formed with an external thread 7 that meshes with the internal thread 4.

[0020] In this embodiment: During the assembly of the front housing 1 and the rear housing 2, the front housing 1 drives the positioning rod 3 to align with the positioning hole 5 and inserts it. After the insertion is completed, the mating ends of the front housing 1 and the rear housing 2 are effectively aligned. Then, the locking bolt 6 is passed through the positioning hole 5 and connected to the inner wall of the positioning rod 3. Then, a hex wrench is used to align with the hexagonal hole 8, and the locking bolt 6 is driven to rotate by the hexagonal wrench. The rotating locking bolt 6 drives the external thread 7 to engage with the internal thread 4 until the locking bolt 6 is fully locked. At this time, the positioning rod 3 is restricted to the current position. At this time, the relative position of the front housing 1 and the rear housing 2 is fixed. After the locking bolt 6 is effectively locked, the sealing ring on the mating end face of the front housing 1 and the rear housing 2 is squeezed and deformed, effectively filling the space between the front housing 1 and the rear housing 2, improving the sealing performance of the connection position. After the connection is completed, the connection point is not visible from the outside, which is more aesthetically pleasing. Compared with illuminated signs where the connection point is visible from the outside, it is more easily accepted by buyers.

[0021] Please refer to this carefully. Figure 3 The inner diameter of the narrow part of the positioning hole 5 is equal to the outer diameter of the positioning rod 3, and the inner diameter of the wide part of the positioning hole 5 is equal to the outer diameter of the end head of the locking bolt 6.

[0022] In this embodiment: during the docking process of the positioning rod 3 and the positioning hole 5, the positioning rod 3 and the narrow part of the positioning hole 5 are inserted into each other. After the positioning rod 3 and the narrow part of the positioning hole 5 are inserted into each other, the docking ends of the front housing 1 and the rear housing 2 are in a relatively aligned state. After the locking bolt 6 is fully tightened, the end of the locking bolt 6 is located on the inner wall of the wide part of the positioning hole 5, thus effectively "hiding" the end of the locking bolt 6, so that there is no obvious connection point from the outside.

[0023] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
