[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 Figure 1-3This utility model provides a technical solution: a waterproof structure for the tail end of an LED light strip, including an LED light strip body 1. A composite sealing sleeve 2 is fitted onto the tail end of the LED light strip body 1. The composite sealing sleeve 2 consists of an elastic silicone layer 21, a reinforcing fiber layer 22, and a conductive metal mesh layer 23, arranged sequentially from the outside to the inside, and is tightly fitted to the connecting end of the LED light strip body 1. A fixing seat 4 is provided at the end of the LED light strip body 1 connected to the composite sealing sleeve 2. Elastic claws 5 are provided on both sides of the fixing seat 4. A docking part 3 is provided in the middle of the outer end of the composite sealing sleeve 2. The inner walls on both sides of the docking part 3 are provided with parts that cooperate with the elastic claws 5. The locking groove 31 and the composite sealing sleeve 2 are uniformly provided with several annular reinforcing ribs 6 on the outside. When the LED strip body 1 is connected to the composite sealing sleeve 2, the elastic silicone layer 21 first plays a preliminary sealing role. Its flexibility allows it to fit tightly to the shape of the LED strip body 1, maintaining good sealing performance even under bending or stretching. The reinforcing fiber layer 22 enhances the structural strength of the entire composite sealing sleeve 2, preventing damage caused by external pressure or physical deformation. The conductive metal mesh layer 23 not only provides additional shielding protection but also assists in heat dissipation, ensuring the internal circuitry. For safe operation, the fixing seat 4 is locked in place by the elastic claws 5 on both sides engaging with the grooves 31 on the inner wall of the docking part 3. This design allows for quick installation without additional tools, while ensuring the stability of the connection. The annular reinforcing rib 6 further improves the overall stability and compressive strength of the structure, preventing deformation or damage caused by external factors. This structure solves the problem of waterproofing failure caused by cracks and loosening of simple silicone seals or rubber sleeves in existing technologies. It also overcomes the shortcomings of traditional waterproof structures, such as complex installation and inconvenient maintenance, achieving both excellent waterproofing performance and ease of installation and maintenance. For long-term maintenance, the elastic silicone layer 21 has several micropores, and the annular reinforcing ribs 6 are evenly distributed on the outer wall of the elastic silicone layer 21. When the LED light strip body 1 is connected to the composite sealing sleeve 2, the elastic silicone layer 21, through its unique micropore design, can absorb and alleviate the stress caused by external pressure or physical deformation without affecting the sealing performance. At the same time, the annular reinforcing ribs 6 provide additional support for the elastic silicone layer 21, preventing deformation or damage caused by long-term use or external factors. The conductive metal mesh layer 23 is woven into a mesh and covers the inner wall of the reinforcing fiber layer 22. Furthermore, an insulating pad 7 is provided between the conductive metal mesh layer 23 and the LED strip body 1. When the LED strip body 1 is operating, the conductive metal mesh layer 23 effectively blocks external electromagnetic interference, protecting the internal circuitry from being affected. The insulating pad 7 prevents current from flowing from the conductive metal mesh layer 23 to the LED strip body 1, avoiding potential short-circuit risks. This not only enhances the electromagnetic interference resistance of the LED strip body 1 but also improves the overall structural strength and stability through the tight bond between the conductive metal mesh layer 23 and the reinforcing fiber layer 22.This design ensures excellent performance and reliable operation even under complex electromagnetic environments or physical stress. The mounting base 4 has a double-layer structure with two outer layers: rigid plastic on both sides and a soft rubber material in the middle. The outer layers provide robust mechanical support and shape retention, while the inner layer offers excellent sealing and cushioning during installation. When the LED strip body 1 is connected to the composite sealing sleeve 2, the rigid plastic outer layer of the mounting base 4 ensures structural stability and durability, preventing deformation due to external physical impact or long-term use. Simultaneously, the soft rubber inner layer tightly adheres to the LED strip body 1, filling any minor gaps and enhancing waterproofing. It can also adapt to slight dimensional differences or irregular surfaces. This not only achieves a secure and reliable fixing effect but also ensures good sealing and resistance through the synergistic effect of the inner and outer layers. The groove 31 has several evenly distributed protrusions 32 on its inner wall, and the outer wall of the protrusions 32 has an arc-shaped surface structure. When the elastic claw 5 is engaged and locked with the groove 31, the protrusions 32 provide progressive resistance through their arc-shaped outer walls, ensuring a smooth transition of the elastic claw 5 during insertion and a firm lock in the final position. This enhances the connection strength between the mating part 3 and the fixing seat 4, preventing loosening due to vibration or external force. The inner end of the composite sealing sleeve 2 has a chamfered part 8, and the inner wall of the chamfered part 8 is provided with flexible sealant 9. During installation, the flexible sealant 9 fills any tiny gaps between the composite sealing sleeve 2 and the LED light strip body 1, ensuring a complete seal between the two. This not only enhances the waterproof performance at the interface, preventing moisture or humidity from entering, but also provides additional cushioning through the elastic properties of the flexible sealant 9, absorbing and mitigating the effects of external pressure or vibration.

[0018] Working principle: When using this waterproof structure at the end of the LED light strip, first align the chamfered part 8 of the composite sealing sleeve 2 with the end of the LED light strip body 1. Using the guiding effect of the chamfered part 8, the composite sealing sleeve 2 can be smoothly fitted into the LED light strip body 1. As the composite sealing sleeve 2 is gradually pushed in, the flexible sealant 9 on the inner wall begins to fill the tiny gap between them, ensuring a tight fit. Then, when the composite sealing sleeve 2 is fully fitted, the elastic claws 5 on both sides of the fixing base 4 will contact the groove 31 on the inner wall of the mating part 3. Because the inner wall of the groove 31 is evenly distributed with protrusions 32, these protrusions... The arc-shaped outer wall of point 32 provides progressive resistance, allowing the elastic claw 5 to smoothly transition during insertion and ultimately achieve a firm lock. At this time, the multi-layer structure in the composite sealing sleeve 2, from the outside to the inside, the elastic silicone layer 21, the reinforcing fiber layer 22, and the conductive metal mesh layer 23, will fit tightly against the connection end of the LED light strip body 1, while the annular reinforcing rib 6 provides additional support for the entire structure. Finally, the mechanical support provided by the inner and outer layers of the fixing seat 4 and the sealing and buffering effect brought by the soft rubber inner layer further ensure the stability and reliability after installation, thus completing a series of tasks.

[0019] Although the present invention 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 the present invention should be included within the protection scope of the present invention.
