Description

Technical Field

[0001] This utility model relates to the field of LED light strip technology, and more specifically, to a waterproof structure for LED light strips. Background Technology

[0002] LED light strips are widely used in outdoor lighting, landscape decoration, and special environment lighting applications due to their energy-saving, high efficiency, and flexible installation. However, these application scenarios often involve humid, dusty, or other harsh environments, thus placing high demands on the waterproof performance of LED light strips. To meet this requirement, existing technologies typically use waterproof covers to encapsulate LED light strips to isolate them from external moisture and dust. However, in actual use, the installation of waterproof covers is often quite complex, usually requiring the use of special tools or the application of significant external force, resulting in low installation efficiency. In addition, some structures may fail to provide waterproof seals due to uneven stress during installation, thereby affecting the lifespan and stability of the LED light strip.

[0003] In scenarios requiring maintenance, replacement, or adjustment of LED light strips, the disassembly of the waterproof cover also presents numerous inconveniences. Existing structures often use methods such as glue sealing, clips, or threaded connections for fixation. Among these, glue sealing structures cannot be reused, and once disassembled, the waterproof cover must be replaced. While clips and threaded connections can be reinstalled, after long-term use, they may become difficult to disassemble due to aging or dust accumulation, and may even damage the waterproof components. In addition, improper operation during disassembly may also affect the waterproof effect, exposing the LED light strip to a humid environment, thereby reducing its reliability. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] In view of the problems existing in the prior art, this utility model provides a waterproof structure for LED light strips to solve the technical problems mentioned in the background art.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a waterproof structure for an LED light strip, comprising a mounting base and a light strip, wherein the light strip is mounted on the mounting base, and a waterproof cover is connected to the mounting base via a quick-release mechanism. The quick-release mechanism includes an insert rod, a fixing sleeve, snap-fit ​​pieces, snap grooves, a compression spring, and a quick-release mechanism. The insert rod is fixed on the mounting base and is inserted into the waterproof cover. The fixing sleeve is inserted into the top of the insert rod. Multiple sets of snap-fit ​​pieces are distributed on the inner wall of the fixing sleeve. Multiple sets of snap grooves are distributed on the outer wall of the insert rod. Multiple sets of compression springs are distributed on the inner top surface of the fixing sleeve. The quick-release mechanism includes a quick-release sleeve, a compression spring, a snap sleeve, a sliding groove, a rotating sleeve, and a snap block. The quick-release sleeve slides inside the insert rod. The two ends of the compression spring are respectively connected to the inner wall of the insert rod and the bottom surface of the quick-release sleeve. Multiple sets of snap sleeves slide on the outer wall of the insert sleeve and are connected to the quick-release sleeve. The sliding groove is located on the outer side of multiple sets of snap sleeves. The rotating sleeve is rotatably mounted on the outer wall of the fixing sleeve. Multiple sets of snap blocks are distributed on the inner side of the rotating sleeve and are slidably connected to the fixing sleeve.

[0008] The present invention is further configured such that a limiting mechanism is provided on the outer side of the fixed sleeve. The limiting mechanism includes a mounting ring, a slide bar, a positioning block, a partition block, a telescopic spring, a limiting sleeve, and a push spring. The mounting ring is fixed on the top surface of the rotating sleeve. Multiple sets of slide bars are provided and distributed on the top surface of the mounting ring. The positioning block slides on multiple sets of slide bars. Multiple sets of partition blocks are provided and distributed on the outer wall of the fixed sleeve. Multiple sets of telescopic springs are provided and are respectively connected to multiple sets of positioning blocks. The limiting sleeve slides on the outer wall of the fixed sleeve. Multiple sets of push springs are provided and are respectively connected at both ends to the limiting sleeve and the fixed sleeve.

[0009] The present invention is further provided that a sealing gasket is installed on the top surface of the waterproof cover. The sealing gasket provides a better sealing effect when the waterproof cover is connected to the mounting base, ensuring that the waterproof cover effectively blocks external moisture and dust during use, enhancing waterproof performance, and improving the service life and stability of the light strip.

[0010] The present invention is further characterized in that the waterproof cover is made of transparent plastic. The transparent plastic material gives the waterproof cover good light transmittance, which not only maintains the lighting effect of the LED light strip, but also allows the waterproof cover to better integrate with the appearance of the light strip, improving the overall aesthetics.

[0011] This utility model is further configured such that a guide groove is provided at the top of the insertion rod, and a guide block is provided on the inner top surface of the fixing sleeve. Both the guide groove and the guide block are cross-shaped and interlocked. The cross-shaped design of the guide groove and the guide block ensures the accuracy and stability during interlocking, effectively avoids misalignment between the waterproof cover and the insertion rod, and ensures that the waterproof cover can be quickly and accurately connected to the mounting base, improving the convenience and accuracy of installation.

[0012] The present invention is further configured such that the outer wall of the fixing sleeve is provided with a clearance groove, and multiple sets of clearance grooves are provided, each of which is slidably connected to multiple sets of retaining sleeves. The cooperation between the clearance groove and the retaining sleeve allows the retaining sleeve to slide smoothly during installation, ensuring a more secure connection between the waterproof cover and the mounting base. At the same time, it allows the retaining sleeve to smoothly disengage from the snap-fit ​​position when needed, thereby simplifying the installation and disassembly process of the waterproof cover.

[0013] This invention is further configured such that a limiting ring is installed on the outer wall of the fixing sleeve, and limiting grooves are formed on the inner sides of multiple sets of positioning blocks, with each set of limiting grooves slidably connected to the limiting ring. This sliding connection design between the limiting ring and the limiting grooves effectively prevents the waterproof cover from shifting position during installation, ensuring a stable connection between the waterproof cover and the mounting base, avoiding loosening or leakage due to vibration or external force, and further enhancing the waterproof effect and structural stability.

[0014] The present invention is further configured such that the exterior of the multiple sets of positioning blocks and partition blocks are all arc-shaped. The arc-shaped exterior design of the positioning blocks and partition blocks allows them to contact and slide more smoothly during operation, reducing friction and wear, ensuring stability after long-term use, and also reducing the risk of jamming between components, further improving the durability and sealing effect of the structure.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, this utility model provides a waterproof structure for LED light strips, which has the following beneficial effects:

[0017] 1. The quick-installation mechanism, through the insertion design of the plug and the waterproof cover, allows the waterproof cover to be quickly and securely fixed to the mounting base. The cooperation between the plug and the fixing sleeve ensures a stable connection of the waterproof cover, while the interaction between the snap-fit ​​tab and the slot enhances the sealing performance of the waterproof cover, effectively blocking external moisture and dust. In addition, the compression spring not only helps the snap-fit ​​tab to engage tightly, but also ensures that the waterproof cover maintains appropriate pressure during installation by pushing the plug, further improving its protective effect. This design greatly improves the ease of installation, reduces installation time, and ensures the firmness and sealing of the waterproof cover, meeting the high requirements for waterproof performance.

[0018] 2. The quick-release mechanism can quickly release the locking mechanism when disassembling the waterproof cover, reducing the time and effort required for disassembly. Through the cooperation of the locking sleeve and the locking block, the quick-release sleeve slides and compresses the spring, ensuring that the waterproof cover can smoothly detach from the mounting base during disassembly. In particular, the sliding design of the quick-release sleeve and the disengagement design of the locking piece ensures the convenience and reliability of the disassembly process, avoiding the trouble caused by jamming or structural damage during the disassembly of traditional waterproof covers. In addition, the cooperation of the push spring and the telescopic spring makes the disengagement of the limit sleeve and the positioning block smoother, and the rotation operation of the rotating sleeve further simplifies the disassembly process, allowing users to quickly and safely complete the disassembly of the waterproof cover.

[0019] 3. The limiting mechanism, through the combination of a limiting ring, a positioning block, and a partition block, provides stable positioning and effective limiting during the installation of the waterproof cover, preventing it from loosening or shifting due to vibration or external force during use. The interlocking design between the positioning block and the partition block ensures the stability of the limiting sleeve, while the presence of the telescopic spring ensures the elastic return of the positioning block, further enhancing the firm connection between the waterproof cover and the mounting base. During installation, the limiting mechanism effectively prevents misalignment or loosening between the waterproof cover and the mounting base, ensuring the tightness of the sealing gasket and the long-term maintenance of waterproof performance. This structure makes the assembly of the waterproof cover more precise and avoids sealing failure caused by improper positioning or excessive component gaps. Attached Figure Description

[0029] Please see Figures 1-5 A waterproof structure for an LED light strip includes a mounting base 1 and a light strip 2. The light strip 2 is mounted on the mounting base 1. A waterproof cover 3 is connected to the mounting base 1 via a quick-release mechanism. The quick-release mechanism includes a rod 4, a fixing sleeve 5, snap-fit ​​pieces 6, slots 7, compression springs 8, and a quick-release mechanism. The rod 4 is fixed to the mounting base 1 and inserts into the waterproof cover 3. The fixing sleeve 5 is inserted into the top of the rod 4. Multiple sets of snap-fit ​​pieces 6 are distributed on the inner wall of the fixing sleeve 5. Multiple sets of slots 7 are distributed on the outer wall of the rod 4. Multiple compression springs 8 are provided. The quick-release mechanism includes a quick-release sleeve 9, a compression spring 10, a retaining sleeve 11, a sliding groove 12, a rotating sleeve 13, and a locking block 14, all distributed on the top surface of the fixed sleeve 5. The quick-release sleeve 9 slides inside the insert rod 4. The two ends of the compression spring 10 are respectively connected to the inner wall of the insert rod 4 and the bottom surface of the quick-release sleeve 9. The retaining sleeve 11 is provided with multiple sets that slide on the outer wall of the insert sleeve and are connected to the quick-release sleeve 9. The sliding groove 12 is provided on the outer side of the multiple sets of retaining sleeves 11. The rotating sleeve 13 is rotatably installed on the outer wall of the fixed sleeve 5. The locking block 14 is provided with multiple sets that are distributed on the inner side of the rotating sleeve 13 and are slidably connected to the fixed sleeve 5.

[0030] A limiting mechanism is provided on the outer side of the fixed sleeve 5. The limiting mechanism includes a mounting ring 15, a slide bar 16, a positioning block 17, a partition block 18, a telescopic spring 19, a limiting sleeve 20, and a push spring 21. The mounting ring 15 is fixed to the top surface of the rotating sleeve 13. Multiple sets of slide bars 16 are provided on the top surface of the mounting ring 15. The positioning block 17 slides on multiple sets of slide bars 16. Multiple sets of partition blocks 18 are provided on the outer wall of the fixed sleeve 5. Multiple sets of telescopic springs 19 are provided and are respectively connected to multiple sets of positioning blocks 17. The limiting sleeve 20 slides on the outer wall of the fixed sleeve 5. Multiple sets of push springs 21 are provided and are respectively connected at both ends to the limiting sleeve 20 and the fixed sleeve 5.

[0031] A sealing gasket 22 is installed on the top surface of the waterproof cover 3. The function of the sealing gasket 22 is to provide an additional sealing layer, enhance the sealing between the waterproof cover 3 and the mounting base, ensure that the waterproof cover 3 can effectively block moisture and dust, prevent water vapor from entering the interior of the light strip, and ensure the long-term stable operation of the light strip.

[0032] The waterproof cover 3 is made of transparent plastic. The transparent plastic material allows the waterproof cover 3 to provide necessary waterproof protection without affecting the lighting effect of the LED light strip and maintaining the light transmission of the light strip. At the same time, the durability and processability of the plastic material give it good impact resistance and weather resistance.

[0033] The top of the insertion rod 4 has a guide groove 23, and the top surface of the inner sleeve 5 has a guide block 24. Both the guide groove 23 and the guide block 24 are cross-shaped and interlocked. The cross-shaped interlocking design of the guide groove 23 and the guide block 24 ensures precise alignment between the insertion rod 4 and the sleeve 5, preventing deviations during insertion. This allows the waterproof cover 3 to be stably and accurately installed on the seat, thereby improving the accuracy and efficiency of the installation process.

[0034] The outer wall of the fixing sleeve 5 is provided with a relief groove 25, and multiple sets of relief grooves 25 are provided, each of which is slidably connected to multiple sets of retaining sleeves 11. The design of the relief groove 25 and the retaining sleeves 11 allows the retaining sleeves 11 to slide smoothly during insertion, thereby avoiding excessive resistance during insertion, ensuring that the waterproof cover 3 can be easily installed in place, and can also be easily detached during disassembly, facilitating maintenance and replacement.

[0035] A limiting ring 26 is installed on the outer wall of the fixed sleeve 5, and a limiting groove 27 is opened on the inner side of multiple positioning blocks 17. The multiple limiting grooves 27 are slidably connected to the limiting ring 26. The design of the limiting ring 26 and the limiting groove 27 enables the positioning blocks 17 to be accurately positioned during installation and prevents the waterproof cover 3 from being displaced or loosened due to external forces during use, thereby ensuring that the waterproof cover 3 remains tightly sealed for a long time and improving sealing performance and safety.

[0036] The multiple sets of positioning blocks 17 and partition blocks 18 are all designed with an arc shape on the outside. The arc shape design reduces the friction between the positioning blocks 17 and partition blocks 18, ensuring that they can slide and fit smoothly, while reducing wear, extending the service life of the components, and enhancing the stability and durability of the overall structure.

[0037] In this embodiment, when the waterproof cover 3 needs to be installed, the waterproof cover 3 is inserted into the insertion rod 4, the fixing sleeve 5 is inserted into the top of the insertion rod 4, and the positioning insertion is achieved through the guide block 24 and the guide groove 23. The top of the insertion rod 4 compresses multiple sets of compression springs 8, and multiple sets of snap-fit ​​pieces 6 are engaged in the slot 7. The multiple sets of compression springs push the insertion rod 4 to make the slot 7 and snap-fit ​​pieces 6 lock together. At the same time, multiple sets of snap-fit ​​sleeves 11 abut against the bottom surface of multiple sets of snap-fit ​​blocks 14, causing the quick-release sleeve 9 to slide and compress the compression spring 10. The push spring 21 pushes the limiting sleeve 20 to abut against the outer wall of multiple sets of positioning blocks 17, so that the multiple sets of positioning blocks 17 are respectively engaged between multiple sets of partition blocks 18 and compress the telescopic spring 19, limiting the installation ring 15 and the rotating sleeve 13. The bottom end of the fixing sleeve 5 abuts against the outer wall of the waterproof cover 3 and compresses the sealing gasket 22, thus completing the quick installation of the waterproof cover 3.

[0038] More specifically, when the waterproof cover 3 needs to be disassembled, the limiting sleeve 20 is pushed to release the contact with multiple sets of positioning blocks 17 and to compress multiple sets of push springs 21. The multiple sets of telescopic springs 19 are elastically reset to drive the multiple sets of positioning blocks 17 to slide along the slide bar 16 to release the contact with multiple sets of partition blocks 18, thereby releasing the restriction on the mounting ring 15 and the rotating sleeve 13. The rotating sleeve 13 is rotated to drive the multiple sets of locking blocks 14 to disengage from the multiple sets of slide grooves 12, thereby releasing the contact with multiple sets of abutting blocks. Then, the compression spring 10 is reset to push the quick-release sleeve 9 to abut against multiple sets of locking pieces 6, thereby causing multiple sets of locking pieces 6 to disengage from the slot 7, releasing the locking of the insertion rod 4. The compression spring 8 is reset to push the fixing sleeve 5 to disengage from the insertion rod 4, releasing the tightness of the waterproof cover 3, thus completing the disassembly of the waterproof cover 3.

[0039] In summary, when the overall equipment is in use or operation: when the waterproof cover 3 needs to be installed, the waterproof cover 3 is inserted into the insertion rod 4, the fixing sleeve 5 is inserted into the top of the insertion rod 4, and the positioning is achieved through the guide block 24 and the guide groove 23. The top of the insertion rod 4 compresses multiple sets of compression springs 8, and multiple sets of snap-fit ​​pieces 6 are engaged in the slot 7. The multiple sets of compression springs push the insertion rod 4 to make the slot 7 and snap-fit ​​pieces 6 lock together. At the same time, multiple sets of snap-fit ​​sleeves 11 abut against the bottom surface of multiple sets of snap-fit ​​blocks 14, causing the quick-release sleeve 9 to slide and compress the compression spring 10. The push spring 21 pushes the limiting sleeve 20 to abut against the outer wall of multiple sets of positioning blocks 17, so that the multiple sets of positioning blocks 17 are respectively engaged between multiple sets of partition blocks 18 and compress the telescopic spring 19, limiting the installation ring 15 and the rotating sleeve 13. The bottom end of the fixing sleeve 5 abuts against the outer wall of the waterproof cover 3 and compresses the sealing gasket 22, thus completing the quick installation of the waterproof cover 3.

[0040] When the waterproof cover 3 needs to be disassembled, the limiting sleeve 20 is pushed to release the contact with the multiple sets of positioning blocks 17 and to compress the multiple sets of push springs 21. The multiple sets of telescopic springs 19 are elastically reset to drive the multiple sets of positioning blocks 17 to slide along the slide bar 16 to release the contact with the multiple sets of partition blocks 18, thereby releasing the restriction on the mounting ring 15 and the rotating sleeve 13. The rotating sleeve 13 is rotated to drive the multiple sets of locking blocks 14 to disengage from the multiple sets of slide grooves 12, thereby releasing the contact with the multiple sets of abutting blocks. Then, the compression spring 10 is reset to push the quick-release sleeve 9 to abut against the multiple sets of locking pieces 6, thereby causing the multiple sets of locking pieces 6 to disengage from the slot 7, releasing the locking of the insertion rod 4. The compression spring 8 is reset to push the fixing sleeve 5 to disengage from the insertion rod 4, releasing the tightness of the waterproof cover 3, thus completing the disassembly of the waterproof cover 3.
