Description

Technical Field

[0001] This utility model relates to the field of LED display technology, specifically to a screen protection structure for LED displays. Background Technology

[0002] LED displays are widely used in outdoor advertising, indoor exhibition halls, transportation hubs, and other scenarios due to their high brightness and excellent display effects. However, existing LED display screen protection solutions have significant shortcomings: Most of them use single-layer tempered glass or plastic cover plates, which can only achieve basic scratch protection and cannot resist external impacts (such as outdoor gravel impacts or indoor accidental collisions). Furthermore, their waterproof and dustproof performance depends on the overall sealing of the display screen, and local damage can easily lead to damage to the internal modules. Protective covers are mostly fixed by bolts or glued, requiring professional tools to disassemble and easily damaging the screen frame. They also result in low efficiency when replacing or repairing LED modules later. Outdoor LED displays are prone to glare due to strong light reflection, which affects the viewing experience. Existing protective structures are not optimized for anti-glare requirements. Utility Model Content

[0003] (a) Technical problems to be solved To address the shortcomings of existing technologies, this utility model provides an LED display screen protection structure that solves the problems of limited protection functions and inconvenience in disassembly and maintenance of existing LED display screen protection structures.

[0004] (II) Technical Solution To achieve the above objectives, this utility model specifically adopts the following technical solution: An LED display screen is mounted on the inner wall of the mounting frame away from the stepped mounting groove. The air nozzle is connected to the limiting inflation soft rubber strip and extends to the outside of the mounting frame. A dust cap is provided on the air nozzle to facilitate inflation and deflation.

[0005] Furthermore, the outer layer is a tempered glass layer, with a nano-silica anti-glare coating sprayed on the outer surface and a PET explosion-proof film attached to the inner surface, which not only ensures light transmittance but also reduces glare and prevents glass from shattering and flying. The middle layer is a porous silicone pad layer with heat dissipation holes evenly distributed on the silicone pad layer, which has both impact absorption and heat conduction functions. The inner layer is a PC endurance board, and the edges of the PC board are integrally formed with upward-protruding sealing ribs, which are used to cooperate with the sealing ring to achieve dust and water protection.

[0006] Furthermore, the outer, middle, and inner layers are bonded and fixed together with optically transparent adhesive to ensure light transmittance and not affect the display effect.

[0007] Furthermore, the locking assembly includes a fixed base, a rotating latch, a rubber block, and an elastic buckle. The fixed base is fixedly connected to the mounting frame, the rotating latch is hinged to the fixed base and can rotate around the pin, the elastic buckle is set on the fixed base and used to lock the position of the rotating latch, and the rubber block is fixed on the side of the rotating latch facing the protective assembly. The two are fixedly bonded with high-temperature resistant adhesive, the material of which is EPDM rubber, to ensure flexible contact when pressed to avoid damage to the protective assembly, and the rubber block abuts against the edge of the protective assembly.

[0008] Furthermore, the limiting inflatable soft rubber strip is embedded in the fitting groove opened on the inner wall of the mounting frame, and it is completely located in the fitting groove when it is not inflated.

[0009] (III) Beneficial Effects Compared with the prior art, the present invention provides a protective structure for an LED display screen, which has the following beneficial effects: This utility model features a three-layer composite protective component. The outer layer of tempered glass provides high-strength scratch resistance, the middle layer of acrylic cushions impact, and the inner layer of silicone prevents screen scratches, offering comprehensive protection for the display screen. It is easy and efficient to install and remove, requiring no tools for locking and unlocking, significantly improving maintenance efficiency. The installation frame size can be adjusted according to the LED display screen specifications. The light transmittance of the three-layer protective component meets display requirements, making it suitable for various indoor and outdoor LED display screen scenarios.

[0012] 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.

[0013] Example like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, one embodiment of this utility model proposes an LED display screen protection structure, including a protection component 1, a mounting frame 2, a locking component 3, an air nozzle 4, and a limiting inflatable soft rubber strip 5. The protection component 1 includes an outer layer 101, a middle layer 102, and an inner layer 103, and the three layers are fixedly connected in sequence. The outer layer 101 is a tempered glass layer with a nano-silica anti-glare coating sprayed on the outer surface and a PET explosion-proof film attached to the inner surface, which not only ensures light transmittance but also reduces glare and prevents glass from flying off after breakage. The middle layer 102 is a porous silicone pad layer with heat dissipation holes evenly distributed on the silicone pad layer, which has both impact absorption and heat conduction functions. The inner layer 103 is a PC endurance board, and the edge of the PC board is integrally formed with upward-protruding sealing ribs, which are used to cooperate with the sealing ring 202 to achieve dust and water protection. The outer layer 101, the middle layer 102, and the inner layer 103 are bonded and fixed together with optical transparent adhesive to ensure light transmittance and not affect the display effect. The inner side of the mounting frame 2 is provided with a stepped mounting groove 201 for installing the protective component 1. A sealing ring 202 is embedded in the bottom of the stepped mounting groove 201. The sealing ring 202 is a nitrile rubber sealing ring. The sealing rib of the PC board of the protective component is tightly fitted with the sealing ring 202 to form a stable sealing connection. Among them, the mounting frame 2 is installed on the frame of the LED display body, so that the protective component 1 is located in front of the screen and provides effective protection for it; Multiple locking components 3 are provided and distributed around the outside of the mounting frame 2 to lock the protective component 1 onto the mounting frame 2, ensuring that the two work together stably. The locking component 3 includes a fixed base 301, a rotary locking tongue 302, a rubber pressure block 303, and an elastic buckle 304. The fixed base 301 is fixedly connected to the mounting frame 2. The rotary locking tongue 302 is hinged to the fixed base 301 and can rotate around the pin. The elastic buckle 304 is set on the fixed base 301 and used to lock the position of the rotary locking tongue 302. The rubber pressure block 303 is fixed on the side of the rotary locking tongue 302 facing the protective component 1. The two are fixedly bonded with high-temperature resistant adhesive. The material is EPDM rubber to ensure flexible contact when pressed to avoid damage to the protective component 1. The rubber pressure block 303 abuts against the edge of the protective component 1. When the protective component 1 is inserted into the mounting slot 201, the rotating locking tongue 302 causes the rubber pressure block 303 to press the edge of the protective component 1, and the elastic buckle 304 locks the rotating locking tongue 302. When disassembling, pressing the rotating locking tongue 302 will rotate it open. A limiting inflatable soft rubber strip 5 is wrapped around the inner wall of the mounting frame 2 away from the stepped mounting groove 201. The air nozzle 4 is connected to the limiting inflatable soft rubber strip 5 and extends to the outside of the mounting frame 2. A dust cap is provided on the air nozzle 4 to facilitate inflation and deflation. Among them, the limiting inflatable soft rubber strip 5 is embedded in the fitting groove opened on the inner wall of the mounting frame 2, and it is completely located in the fitting groove when it is not inflated.

[0014] When assembling the protective structure as a whole, the protective component 1 is placed into the stepped mounting groove 201 of the mounting frame 2, ensuring that the bottom of the protective component 1 is in close contact with the sealing ring 202. The rotating locking tongue 302 of the locking component 3 is rotated, so that the rubber pressure block 303 presses the edge of the protective component 1. At this time, the elastic buckle 304 locks the positioning groove of the rotating locking tongue 302. Then, the limiting inflatable soft rubber strip 5 is placed around and inserted into the fitting groove of the mounting frame 2. The air nozzle 4 is connected to the rubber strip and passes through the side wall of the mounting frame 2. The mounting frame 2 is then fitted onto the frame of the LED display body. The distance between the protective component 1 and the screen is adjusted. Finally, the limiting inflatable soft rubber strip 5 is inflated through the air nozzle 4, so that the rubber strip expands to fill the fitting groove and abuts against the mounting frame 2 and the screen frame, locking the mounting frame 2 onto the screen frame, so that the protective component 1 effectively protects the screen. During use, if disassembly or maintenance is required, first open the dust cap of the air nozzle 4 to release the gas in the limiting inflatable soft rubber strip 5, and the rubber strip will return to the uninflated state. Then, release the lock on the mounting frame 2, and the protective structure can be removed from the screen frame. Press the unlocking end of the rotating locking tongue 302 to separate the rubber pressure block 303 from the edge of the protective component 1, and directly remove the protective component 1 for cleaning or maintenance. After maintenance, reinstall it according to the above assembly steps.

[0015] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
