Technical Field
[0001] This utility model belongs to the field of lighting billboard technology, specifically relating to an LED decorative lighting billboard. Background Technology
[0002] LED decorative lighting billboards are a common form of advertising display. They use high-brightness LED chips to provide bright and eye-catching lighting effects both day and night, attracting people's attention and having a wide range of applications.
[0003] In existing LED decorative lighting billboards, the display panel and outer frame are fixed by bonding and then bolting. This results in insufficient sealing at the joint between the display panel and the outer frame, allowing dust and moisture to enter and affecting the normal operation of the LED chips and circuit boards. Therefore, this utility model proposes an LED decorative lighting billboard. Utility Model Content
[0004] The purpose of this utility model is to provide an LED decorative light billboard to solve the problem of insufficient sealing of LED decorative light billboards mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: an LED decorative lighting billboard, comprising an outer frame, a display panel disposed on the inner side of the outer frame, and multiple corner protectors installed around the outer frame. A sealing mechanism is provided at the joint between the inner side of the outer frame and the display panel. The sealing mechanism consists of a sealing component and an auxiliary component. The sealing component consists of a sealing strip, a sealing block, and a slot. The sealing strip is disposed on the inner side of the outer frame, the slot is opened inside the outer frame, the sealing block is disposed on the inner side of the slot and fixed to the bottom end of the sealing strip, and the auxiliary component is disposed on the side of the outer frame.
[0006] Preferably, the surface of the sealing block is in contact with the inner wall of the slot, and the cross-section of the sealing block is trapezoidal.
[0007] Preferably, the auxiliary component consists of a push block, a push groove, and a limiting component. The push groove is opened at the side edge of the outer frame, the push block is disposed inside the push groove, and the limiting component is disposed at the connection between the bottom end of the push block and the bottom end of the push groove.
[0008] Preferably, the push block has a rectangular cross-section, and the top end of the push block is in contact with the bottom end of the sealing strip.
[0009] Preferably, the limiting component consists of a limiting seat and a limiting groove. The limiting groove is opened on the inner side of the outer frame, and the limiting seat is disposed inside the limiting groove. The top end of the limiting seat is fixed to the bottom end of the push block.
[0010] Preferably, the end cross-section of the limiting seat has a T-shaped structure.
[0011] Preferably, a circuit board is provided on the inner side of the outer frame and on the rear side of the display panel, and LED beads are provided on the inner side of the outer frame.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] By designing a sealing mechanism, the previous method of fixing the display panel and outer frame of LED decorative lighting billboards by simply attaching them together and then passing bolts through them resulted in insufficient sealing. By setting a sealing mechanism at the joint between the display panel and the outer frame, the sealing performance is improved. Furthermore, the sealing components can be replaced according to aging conditions, ensuring that dust and moisture are isolated during use, protecting the LED beads and circuit boards inside the LED decorative lighting billboard, and ensuring the continued use of the LED decorative lighting billboard.

[0018] 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.
[0019] Please see Figures 1 to 3This utility model provides a technical solution: an LED decorative lighting billboard, including an outer frame 2, a display panel 1 disposed inside the outer frame 2, and multiple corner guards 3 installed around the outer frame 2. A sealing mechanism 4 is provided at the joint between the inner side of the outer frame 2 and the display panel 1. The sealing mechanism 4 consists of a sealing component 41 and an auxiliary component 42. The sealing component 41 consists of a sealing strip 411, a sealing block 412, and a slot 413. The sealing strip 411 is disposed inside the outer frame 2, and the slot 413... The sealing block 412 is located inside the outer frame 2, inside the slot 413, and fixed to the bottom end of the sealing strip 411. The auxiliary component 42 is located on the side of the outer frame 2. The surface of the sealing block 412 is in contact with the inner wall of the slot 413. The cross-section of the sealing block 412 is trapezoidal. The auxiliary component 42 consists of a push block 421, a push groove 422, and a limiting component 423. The push groove 422 is located at the side edge of the outer frame 2, and the push block 421 is located in the push groove 422. Inside, the auxiliary component 42 facilitates the disassembly of the sealing component 41. By pushing the push block 421 upward, it slides inside the push groove 422, causing the bottom-fixed limiting seat 4231 to slide within the limiting groove 4232. This push block 421, moving upward, pushes the sealing strip 411, separating the sealing block 412 from the groove 413. The limiting component 423 is located at the connection between the bottom end of the push block 421 and the bottom end of the push groove 422. The cross-section of 421 is rectangular. The top of the pusher 421 is in contact with the bottom of the sealing strip 411. A circuit board is provided on the inner side of the outer frame 2 and on the rear side of the display panel 1. The circuit board is the core component of the LED decorative lighting billboard, which realizes various control functions of the LED beads. LED beads are provided on the inner side of the outer frame 2. An LED bead is a semiconductor light-emitting device. When a forward current passes through it, the electrons and holes inside recombine, thereby converting electrical energy into light energy.
[0020] In this embodiment, preferably, the limiting component 423 consists of a limiting seat 4231 and a limiting groove 4232. The limiting groove 4232 is opened on the inner side of the outer frame 2. The limiting component 423 limits the pushing position of the push block 421. The limiting seat 4231 is disposed inside the limiting groove 4232. The top end of the limiting seat 4231 is fixed to the bottom end of the push block 421. The end cross-section of the limiting seat 4231 has a T-shaped structure.
[0021] The working principle and usage process of this utility model are as follows: After the LED decorative light advertising sign is assembled, a sealing operation is performed. By removing the sealing strip 411 that makes up the sealing component 41, the sealing block 412 is inserted into the inner side of the slot 413. By pressing the sealing strip 411, the sealing block 412 is inserted into the inner side of the slot 413 and then fixed in position by squeezing, thereby sealing the joints of the LED decorative light advertising sign. When the LED decorative light advertising sign is working, through the coordinated work of the power supply, LED beads and circuit board, the LED decorative light advertising sign presents a variety of visual effects according to different needs, so as to attract attention and achieve the purpose of advertising.
[0022] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
