Description

Technical Field

[0001] The utility model relates to the field of light-emitting characters, and in particular to a three-dimensional light-emitting character that is convenient for maintenance. Background Art

[0002] A light-emitting character (LED sign) is a sign made of a character shell, a panel, and a bottom plate with LED as the light source. This kind of sign is widely used in various commercial and public places, such as door heads, corporate culture walls, etc. It not only plays an advertising role but also has the function of beautifying the environment.

[0003] The character shell is generally assembled with the bottom plate through adhesives (such as glass glue, weather-resistant glue) or bolts. When maintenance of the light-emitting character is required (such as repairing, replacing the light strip), the disassembly and assembly of the existing light-emitting character are relatively troublesome and not easy to maintain. The purpose of the utility model is to propose a light-emitting character structure that is convenient for disassembly and assembly to solve the above technical problems and improve the maintenance efficiency. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a three-dimensional light-emitting character that is convenient for maintenance to solve the problems mentioned in the background art.

[0005] To achieve the above purpose, the utility model provides the following technical solutions: including a character shell, a bottom plate, a connecting rod, and a magnet sheet. An installation groove matching the shape of the character shell is opened on the contact surface between the bottom plate and the character shell. The rear end of the connecting rod is fixedly connected to the bottom plate, a limiting groove is opened at the front end of the connecting rod, the front end of the connecting rod can abut against the inner side of the character shell, the magnet sheet is attracted to the connecting rod, the magnet sheet is hinged to the inner side of the character shell and can rotate freely, and when the front end of the connecting rod abuts against the inner side of the character shell, the magnet sheet can abut against the limiting groove.

[0006] To optimize the above technical solution, a further measure is taken: it also includes a reinforcing rib. The reinforcing rib is arranged along the circumferential direction of the character shell on the inner side of the character shell. The reinforcing rib and the character shell are of an integral structure, and through holes for the connecting rod to pass through are formed on the reinforcing rib. The purpose of setting the reinforcing rib is to improve the structural strength of the character shell. At the same time, the connecting rod passing through the through holes can improve the bonding property between the connecting rod and the character shell and improve the overall strength of the light-emitting character.

[0007] As a further improvement of the above technical solution: it also includes a support rib. The support rib is arranged along the circumferential direction of the character shell on the inner side of the character shell. The support rib and the character shell are of an integral structure. The support rib contacts the side surface of the magnet sheet. The purpose of setting the support block is to abut against the magnet sheet to prevent damage to the connection between the magnet sheet and the character shell.

[0008] As a further improvement of the technical solution: the surface of the connecting rod is sprayed with a reflective coating. The purpose of setting the reflective coating is to reflect light and avoid the connecting rod blocking the light after the built-in light source of the light-emitting character forms a dim light spot on the surface of the character shell.

[0009] As an improvement to the foregoing technical solution: A rubber gasket is placed in the installation groove. The purpose of setting the rubber gasket is to improve the sealing performance of the installation groove. When the letter housing presses against the rubber gasket, it can drive the rubber gasket to deform and closely adhere to the gap, thereby blocking water vapor and preventing the inside of the light-emitting letter from getting damp.

[0010] As can be seen from the above description of the structure of the present utility model, compared with the prior art, the present utility model has the following advantages:

[0011] A three-dimensional light-emitting letter provided by the present utility model is convenient for maintenance. By using an external magnet to drive the magnet sheet to deflect, the installation of the letter housing and the bottom plate can be completed quickly, and at the same time, the separation of the letter housing and the bottom plate can be completed quickly, which is convenient for maintenance personnel to maintain the internal structure of the light-emitting letter.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0019] Embodiment

[0020] Please refer to Figures 1-4, the present utility model provides a three-dimensional light-emitting character that is convenient for maintenance, including a character shell 1, a bottom plate 2, a connecting rod 3, a magnet sheet 4, a reinforcing rib 5 and a support rib 6. An installation groove 201 matching the shape of the character shell 1 is opened on the contact surface between the bottom plate 2 and the character shell 1, and a rubber gasket 202 is placed in the installation groove 201.

[0021] The rear end of the connecting rod 3 is fixedly connected to the bottom plate 2. An annular limiting groove 301 is opened at the front end of the connecting rod 3. The front end of the connecting rod 3 can abut against the inner side of the character shell 1. The surface of the connecting rod 3 is sprayed with a reflective coating. In practice, technicians can select one that can be attracted by a magnet according to actual needs for the connecting rod 3.

[0022] The magnet sheet 4 is attracted to the connecting rod 3. The magnet sheet 4 is hinged to the inner side of the character shell 1 and can rotate freely. When the front end of the connecting rod 3 abuts against the inner side of the character shell 1, the magnet sheet 4 can abut against the limiting groove 301. The magnet sheet 4 refers to a sheet-like component made of a magnet or mainly made of a magnet and having magnetism.

[0023] The reinforcing rib 5 is arranged along the circumferential direction of the character shell 1 on the inner side of the character shell 1. The reinforcing rib 5 and the character shell 1 are of an integral structure, and a through hole 501 for the connecting rod 3 to pass through is formed on the reinforcing rib 5.

[0024] The support rib 6 is arranged along the circumferential direction of the character shell 1 on the inner side of the character shell 1. The support rib 6 and the character shell 1 are of an integral structure, and the support rib 6 is in contact with the side surface of the magnet sheet 4.

[0025] Working principle: During installation, the installer uses a magnet to adsorb the magnet sheet 4 outside the character shell 1, aligns the character shell 1 with the installation groove 201, and inserts the connecting rod 3 into the through hole 501 of the reinforcing rib 5 so that the connecting rod 3 abuts against the inner side of the character shell 1. Then, the magnet outside the character shell 1 is removed. At this time, the magnet sheet 4 will closely adhere to the limiting groove 301 on the connecting rod 3 due to the mutual attraction with the connecting rod 3, and the installation process of the light-emitting character is completed.

[0026] During maintenance, the installer uses a magnet to adsorb the magnet sheet 4 outside the character shell 1. The magnet sheet 4 is attracted by the magnet and will move away from the connecting rod 3, so that the limiting groove 301 on the connecting rod 3 is no longer affected by the magnet sheet 4. At this time, the maintainer can easily remove the character shell 1 from the bottom plate 2, which is convenient for maintenance.

[0027] Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded 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 utility model shall be included within the protection scope of the present utility model.
