[0025] 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.

[0026] Reference Figures 2-4 This utility model provides an embodiment of a dual-channel convection heat dissipation type high waterproof LED light string, comprising: a shell 1 serving as the connecting body; fixing blocks 2 fixedly connected to both sides of the top of the shell 1; sliding plates 3 slidably connected to the inner walls of the fixing blocks 2; insert blocks 4 fixedly connected to opposite ends of the sliding plates 3; a first spring 5 provided between the sliding plates 3 and the inner walls of the fixing blocks 2; a fixing ring 6 slidably connected to the outer wall of the fixing blocks 2; an LED light body 7 fixedly connected to the inner wall of the fixing ring 6; and fixing cylinders 8 fixedly connected to both sides of the outer wall of the fixing ring 6. The inner walls of the fixing cylinders 8 are slidably connected to... A limit plate 9 is connected to the inner wall of the limit plate 9, and a button 10 is fixedly connected to the inner wall of the fixed cylinder 8. A second spring 11 is provided between the inner wall of the fixed cylinder 8 and the inner wall of the limit plate 9. A fixing component is provided on the inner wall of the outer shell 1. One end of the first spring 5 is connected to the slide plate 3, and the other end of the first spring 5 is connected to the inner wall of the fixing block 2. One end of the second spring 11 is connected to the limit plate 9, and the other end of the second spring 11 is connected to the inner wall of the fixed cylinder 8. A partition plate 12 is fixedly connected to the inner wall of the outer shell 1. A heat sink 13 is fixedly connected to the inner wall of the outer shell 1. A filter screen 14 is fixedly connected to the inner wall of the outer shell 1.

[0027] Specifically, when the LED light body 7 needs to be inspected, simply press button 10 lightly. After the button 10 is pressed, it will push the insert 4 away from the fixing ring 6. Once the insert 4 is disengaged from the fixing ring 6, the repair personnel can easily remove the LED light body 7 and proceed with the inspection of the fault. If the LED light body 7 is found to be damaged, it can be directly replaced. This convenient disassembly design eliminates the need for complex tools and the time required to disassemble the light string, greatly shortening the repair time. After inspecting or replacing the LED light body 7, during installation, align the fixing ring 6 with the fixing block 2 and insert it. When the fixing ring 6 is fully inserted... Instantly, the first spring 5 releases its elastic potential energy and bounces the slide plate 3. During the bounce, the slide plate 3 drives the insert 4 to quickly insert into the fixing ring 6, thus achieving a stable fixation of the LED lamp body 7. After the button 10 is released, the second spring 11 immediately takes effect, releasing its elastic force and bouncing the limiting plate 9 towards its initial position. As the limiting plate 9 moves, it drives the button 10 to reset, ensuring that the button 10 can return to its original state, preparing for the next possible maintenance operation and avoiding affecting the next use. During the operation of the light string, heat dissipation is crucial. During heat dissipation, the heat sink 13 generates airflow through natural wind, and the airflow passes through... After the filter 14 filters dust, it forms a clean forced convection that blows directly onto the LED lamp body 7 and surrounding heat-generating components, quickly removing heat and lowering the operating temperature. The internal partition plate 12 of the outer shell 1 divides the space, and the airflow generated by the heat sink flows directionally along the heat dissipation channel, then exits from the bottom right end, forming a dual-channel convection heat dissipation. Simultaneously, a waterproof and breathable membrane 21 covers the opening of the heat dissipation channel. The waterproof and breathable membrane 21 is attached to the bottom of the outer shell 1 with double-sided adhesive. The surface of the waterproof and breathable membrane 21 is covered with a large number of micropores, with a diameter between 0.1 and 10 μm and a thickness of 0.01 mm to 0.05 mm. This size is much smaller than the diameter of a water droplet (approximately 100 μm). Based on the principle of liquid surface tension, water cannot penetrate these micropores, thus effectively preventing liquid water from entering the interior of the light string. However, for air, these micropores are sufficient to allow air to circulate smoothly and meet the heat dissipation requirements. After completing all the inspection, installation, and other operations related to the LED light body 7, in order to further improve the waterproof performance of the light string, transparent epoxy resin is used to fill all possible gaps. After the transparent epoxy resin cures, it will form a strong and sealed waterproof layer, completely isolating the internal circuits and components of the light string from the external humid environment, achieving a high waterproof effect in all aspects, and ensuring that the light string operates stably and reliably in various harsh environments. The partition plate 12 divides the outer shell into independent heat dissipation channels and circuit compartments.

[0028] Reference Figure 1 , Figure 5 and Figure 6The fixing assembly includes pressure plates 15 that are slidably connected to both sides of the inner wall of the outer shell 1. A connecting frame 16 is fixedly connected to one opposite end of the pressure plate 15. A pull rod 17 is slidably connected to the inner wall of the connecting frame 16. A connecting plate 18 is fixedly connected to the outer wall of the pull rod 17. A third spring 19 is provided between the connecting plate 18 and the inner wall of the connecting frame 16. A plurality of fixing holes 20 are provided inside the outer shell 1 corresponding to the pull rod 17. The outer wall of the connecting plate 18 is slidably connected to the inner wall of the connecting frame 16. The outer wall of the connecting frame 16 is slidably connected to the inner wall of the outer shell 1. One end of the third spring 19 is connected to the connecting plate 18, and the other end of the third spring 19 is connected to the inner wall of the connecting frame 16.

[0029] Specifically, when it is necessary to fix the lamp tube, the operation process is simple and efficient. First, pull the lever 17. Under the action of force, the lever 17 gradually disengages from the internal space of the fixing hole 20. At this time, since the lever 17 is connected to the connecting bracket 16, the connecting bracket 16 is also moved as the lever 17 moves. When the connecting bracket 16 moves, the pressure plate 15 connected to its front end will move closer to the direction of the lamp tube. In this way, the pressure plate 15 can tightly fix the lamp tube, effectively reducing the problem of loosening or breaking the circuit caused by external force pulling during the subsequent use of the light string, thereby greatly extending the service life of the light string. When the pressure plate 15 is adjusted to the appropriate position, that is, the position where the lamp tube can be fixed securely and just right, the pulling force on the pull rod 17 is released. At this time, the third spring 19 will play its role. Since the third spring 19 was in a compressed state due to pulling the pull rod 17, it has accumulated elastic potential energy. At the moment the pull rod 17 is released, the elastic potential energy is converted into kinetic energy, which makes the connecting frame 16 bounce towards the initial position. During the bounce, the connecting frame 16 will drive the pull rod 17 connected to it to quickly insert into the fixing hole 20, thereby fixing the position of the connecting frame 16 and the pressure plate 15, ensuring that the lamp tube is stably fixed in the corresponding position.

[0030] Working principle: When the LED light body 7 needs to be inspected, press button 10 to move the plug 4. When the plug 4 is moved, it will disengage from the fixing ring 6. At this time, the LED light body 7 can be removed for inspection or replacement. This allows maintenance personnel to quickly locate the fault and handle it without the need for complicated tools or spending a lot of time disassembling the light string, thus shortening the maintenance time. During installation, the fixing ring 6 is inserted into the fixing block 2. When it is inserted into place, the first spring 5 will bounce the slide plate 3. When the button 10 is released, the second spring 11 will spring the limit plate 9, causing the button 10 to reset, thus avoiding affecting the next use. When the lamp tube needs to be fixed, pull the pull rod 17 to disengage it from the fixing hole 20. At this time, pull the connecting bracket 16 to move the pressure plate 15 closer to the lamp tube, thereby reducing the problem of loosening or breaking the circuit of the lamp string due to external force pulling, and extending the service life of the lamp string. When the lever 17 is released to the appropriate position, the third spring 19 will spring the connecting bracket 16. When the connecting bracket 16 is springed, it will drive the lever 17 to insert into the fixing hole 20 for fixation. During heat dissipation, the heat sink 13 generates airflow through natural wind. After the airflow passes through the filter screen 14 to filter dust, it forms a clean forced convection, which blows directly onto the LED lamp body 7 and surrounding heat-generating components, quickly removing heat and reducing the operating temperature. The internal partition plate 12 of the outer shell 1 divides the space, and the airflow generated by the heat sink is distributed along the diffuser. The heat flows in a directional manner and then exits from the bottom of the right end, forming a dual-channel convection heat dissipation. A waterproof and breathable membrane 21 is covered at the bottom of the outer shell 1, allowing air circulation for heat dissipation but preventing liquid water from entering. The micropore diameter on the surface of the waterproof and breathable membrane 21 is (0.1~10μm), which is much smaller than that of a water droplet (about 100μm), and its thickness is 0.01mm-0.05mm. The surface tension prevents water from penetrating. At the end of all operations, transparent epoxy resin is used to fill all gaps to form a waterproof layer, thereby achieving waterproofing.

Although the present 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.
