[0002] LED light strips have been widely used in various fields such as interior decoration, outdoor lighting, display backlighting, and equipment indicator lights due to their advantages such as low energy consumption, uniform light emission, good flexibility, and wide applicability. Modular pluggable LED light strips have become the darling of the market.

[0003] Currently, LED light strips are mainly installed using two methods: adhesive bonding and screw fixing. Adhesive bonding often uses adhesive backing, which is simple to operate, but the adhesion stability of the adhesive is greatly affected by environmental factors such as the cleanliness of the installation surface, temperature, and humidity. Over time, it is prone to peeling and curling. Moreover, the adhesive backing adhering to the inner wall of the lamp housing is not easy to remove during disassembly. Screw fixing, although secure, requires the use of special tools such as screwdrivers, making the installation process cumbersome and inefficient. Furthermore, it is difficult to control the tightening force of the screws, and over-tightening can damage the light strip circuitry. Summary of the Invention

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Example: Please see Figures 1-10 This invention provides a technical solution: a modular pluggable quick-install LED light strip structure, including a mounting frame 2. The mounting frame 2 has a first snap-fit ​​groove 6 and a limiting groove 8, which are interconnected. However, the width and depth of the first snap-fit ​​groove 6 and the limiting groove 8 are not the same. The width of the limiting groove 8 is equal to the width of the limiting post 5. A snap-fit ​​box 9 is snapped into the first snap-fit ​​groove 6. An LED light strip 3 is snapped onto the mounting frame 2. A third snap-fit ​​groove 29 is formed through the LED light strip 3. When the LED light strip 3 is snapped into place... When mounted on frame 2, the limiting post 5 passes through the third snap-fit ​​groove 29 and fixes the LED light strip 3 through the third snap-fit ​​groove 29, so that the LED light strip 3 is snapped and fixed on the mounting frame 2. The snap-fit ​​box 9 is provided with a snap-fit ​​component and the limiting post 5. The snap-fit ​​component includes a snap-fit ​​block 16. When the snap-fit ​​box 9 enters the first snap-fit ​​groove 6, it covers the LED light strip 3 on the mounting frame 2. The snap-fit ​​block 16 retracts and the limiting post 5 moves in the limiting groove 8 and the third snap-fit ​​groove 29, thus completing the snap-fit ​​of the LED light strip 3 on the mounting frame 2.

[0024] In this embodiment, clamping strips 4 are fixedly installed on the mounting frame 2 at equal intervals. LED light strips 3 are located between the clamping strips 4, and anti-slip textures are provided on the adjacent sides of the clamping strips 4. When the LED light strips 3 are placed on the mounting frame 2, the clamping strips 4 can prevent the LED light strips 3 from tilting, avoid wrinkles when using the LED light strips 3, and extend the service life of the LED light strips 3.

[0025] In this embodiment, the first snap-fit ​​groove 6 and the limiting groove 8 are interconnected. The first snap-fit ​​groove 6 is L-shaped, but the sizes of the first snap-fit ​​groove 6 and the limiting groove 8 are not the same. A connecting cavity is provided between the first snap-fit ​​groove 6 and the limiting groove 8. The width of the connecting cavity is smaller than the width of the first snap-fit ​​groove 6, that is, smaller than the width of the snap-fit ​​box 9. At the same time, the width of the connecting cavity is also smaller than the width of the limiting groove 8. However, when the limiting post 5 is in the initial position in the snap-fit ​​box 9, the non-adjacent sides of the two limiting posts 5 are in sliding contact with the side wall of the connecting cavity. When the two limiting posts 5 are unfolded and separated, the distance between the two limiting posts 5 will be greater than the width of the connecting cavity. In this way, the limiting post 5 will not be able to move, thereby fixing the LED light strip 3 with the limiting post 5.

[0026] The limiting post 5 is L-shaped, with the protruding part of the limiting post 5 located at the top, that is, above the LED light strip 3. When the limiting post 5 contacts the LED light strip 3, the limiting post 5 can lock the LED light strip 3 through the protruding part.

[0027] In this embodiment, a fixing post 15 is fixedly installed in the snap-fit ​​box 9, and a first pushing post 13 is installed through the side. The snap-fit ​​block 16 is movably installed in the fixing post 15, and a first through hole matching the snap-fit ​​block 16 is opened in the fixing post 15. At the same time, a second snap-fit ​​groove 18 matching the end of the snap-fit ​​block 16 is opened in the limiting post 5. When the snap-fit ​​block 16 retracts into the fixing post 15, the snap-fit ​​block 16 will separate from the second snap-fit ​​groove 18. In this way, the limiting post 5 can slide on the fixing post 15, so that the limiting post 5 can limit and fix the LED light strip 3. Before the snap-fit ​​block 16 separates from the second snap-fit ​​groove 18, the two limiting posts 5 are in the initial state, the snap-fit ​​box 9 can enter the first snap-fit ​​groove 6, and the limiting post 5 can enter the limiting groove 8 through the connecting cavity.

[0028] In this embodiment, a second pushing column 17 is movably installed in the fixed column 15. The two ends of the second pushing column 17 are in sliding contact with the first pushing column 13 and the locking block 16 through the inclined side. When the first pushing column 13 is pushed and moves into the fixed column 15, the first pushing column 13 can drive the second pushing column 17 to move laterally in the fixed column 15. When the second pushing column 17 moves, it can simultaneously drive the locking block 16 to move and drive the locking block 16 to retract into the fixed column 15. In this way, the locking block 16 will separate from the second locking groove 18 in the limiting column 5, so that the limiting column 5 slides on the fixed column 15.

[0029] In this embodiment, the fixing post 15 is fitted with a first elastic element 14, which is a spring. The first elastic element 14 is fixedly connected to the limiting post 5. At the same time, the first elastic element 14 does not contact the locking block 16. That is, the diameter of the first elastic element 14 is greater than the depth of the locking block 16 extending out of the fixing post 15. This can avoid interference between the first elastic element 14 and the locking block 16. At the same time, the first pushing post 13 does not contact the first elastic element 14. Instead, the first pushing post 13 is located between the two first elastic elements 14 to avoid contact between the first pushing post 13 and the first elastic element 14.

[0030] In this embodiment, a connecting post 11 is fixedly installed in the limiting groove 8, and a connecting groove 19 matching the connecting post 11 is opened in the limiting post 5. When the limiting post 5 enters the limiting groove 8 through the communicating cavity, the limiting post 5 will contact the connecting post 11 through the connecting groove 19. In this way, when the limiting post 5 moves, the connecting post 11 can ensure the movement stability of the limiting post 5, and ensure that the two limiting posts 5 are simultaneously and at the same angle to lock and fix the LED light strip 3.

[0031] In this embodiment, the mounting frame 2 also movably mounts a limiting block 10, an ejector post 22, a rotating post 24, and a second elastic member 25. The second elastic member 25 is fixedly mounted at the lower end of the limiting block 10 and is a spring. The mounting frame 2 also has a piston cavity 12. An ejector plate 7 is fixedly mounted on the top of the ejector post 22. The top of the ejector plate 7 is located on the surface of the mounting frame 2. When the LED light strip 3 is mounted on the surface of the mounting frame 2, the LED light strip 3 can cause the ejector plate 7 to extend into the interior of the mounting frame 2. A piston post 23 is movably mounted in the piston cavity 12, and a sliding block 28 is fixedly mounted on one side of the piston post 23.

[0032] One side of the ejector post 22 is provided with a bevel that matches the first push post 13, that is, the ejector post 22 can drive the first push post 13 to move. At the same time, the lower end of the ejector post 22 extends into the piston cavity 12, and the ejector post 22 can move in the piston cavity 12 and drive the piston post 23 to move.

[0033] In this embodiment, a spiral groove 27 is provided on the rotating column 24, and a telescopic cavity 26 is provided inside the limiting block 10. The sliding block 28 is matched and connected with the spiral groove 27. When the piston column 23 moves, it will drive the rotating column 24 to rotate downward through the sliding block 28 and the spiral groove 27. In this way, when the rotating column 24 moves downward, it will compress the second elastic element 25.

[0034] A vertical channel is provided in the telescopic cavity 26. A connecting slider is fixedly installed on the part of the rotating column 24 located in the telescopic cavity 26. The connecting slider is located in the vertical channel. That is, when the snap-fit ​​box 9 moves from the second inclined surface 21 to the limiting block 10, the limiting block 10 will move down through the vertical channel on the surface of the rotating column 24 via the connecting slider, but will not cause the rotating column 24 to rotate. The downward movement height of the limiting block 10 is equal to the depth of the telescopic cavity 26, and will compress the second elastic element 25 until the snap-fit ​​box 9 separates from the limiting block 10. When the piston column 23 moves from the first inclined surface 20 to the second inclined surface 21, the sliding block 28 on the piston column 23 will drive the rotating column 24 to rotate and drive the limiting block 10 to move down, thereby releasing the limitation of the limiting block 10 on the snap-fit ​​box 9.

[0035] The maximum downward movement distance of the limit block 10 is equal to the movement distance of the rotating column 24 in the telescopic cavity 26.

[0036] The limiting block 10 has a first inclined surface 20 and a second inclined surface 21 on its two sides respectively. The inclination of the first inclined surface 20 and the second inclined surface 21 are different. The limiting block 10 is also located in the first snap-fit ​​groove 6. The distance between the side of the limiting block 10 facing the first inclined surface 20 and the inner wall of the first snap-fit ​​groove 6 is equal to the width of the snap-fit ​​box 9. The distance between the side of the limiting block 10 facing the second inclined surface 21 and the inner wall of the first snap-fit ​​groove 6 is greater than or equal to the width of the snap-fit ​​box 9.

[0037] The lowest point of the first inclined surface 20 is higher than the bottom wall of the first snap-fit ​​groove 6, while the lowest point of the second inclined surface 21 is flush with the bottom wall of the first snap-fit ​​groove 6. That is, when the snap-fit ​​box 9 is located on the second inclined surface 21 side of the limiting block 10, the snap-fit ​​box 9 can drive the limiting block 10 to move down through the second inclined surface 21, and move to the other side through the top surface of the limiting block 10 until the snap-fit ​​box 9 can no longer move. The limiting block 10 returns to its original position under the action of the second elastic member 25, thereby completing the restriction of the snap-fit ​​box 9 and strengthening the snap-fit ​​fixing of the LED light strip 3 by the limiting post 5.

[0038] Furthermore, the inclined surface of the limiting block 10 facing the limiting groove 8, that is, the first inclined surface 20, can limit the snap-fit ​​box 9 to prevent the snap-fit ​​box 9 from passing through the limiting block 10.

[0039] A lighting device includes a lamp housing 1 and a mounting frame 2 installed at equal intervals in the lamp housing 1, including a modular pluggable quick-install LED light strip structure.

[0040] When the LED light strip 3 is pressed onto the mounting frame, the limit post extends and clamps the light strip automatically through the linkage of the ejector plate 7, ejector post 22, first push post 13, and second push post 17, without the need for additional tools or manual manipulation.

[0041] Pushing the limiting post 5 inward will release the latching of the light strip. At the same time, the ejector structure will lift the light strip and unlock the limiting block from restricting the latching box. Both the latching box 9 and the LED light strip 3 can be quickly removed for easy maintenance, replacement and recycling. The working principle of this embodiment is as follows: In use, the snap-fit ​​box 9 is placed into the first snap-fit ​​slot 6. After entering the first snap-fit ​​slot 6, the snap-fit ​​box 9 first contacts the limiting block 10. The snap-fit ​​box 9 moves the limiting block 10 downwards via the second inclined surface 21. The snap-fit ​​box 9 passes the top of the limiting block 10 and moves to the other side of the limiting block 10. At the same time, the limiting post 5 in the snap-fit ​​box 9 is also in its initial position and moves together into the limiting slot 8 through the connecting cavity. Moreover, the limiting block 10 limits and fixes the snap-fit ​​box 9 via the first inclined surface 20. Then, the LED light strip 3 is placed on the surface of the mounting frame 2. The limiting post 5 on the snap-fit ​​box 9 passes through the third snap-fit ​​slot 29. Simultaneously, after the LED light strip 3 is installed on the surface of the mounting frame 2, it drives the ejector plate. 7 moves into the mounting frame 2. When the ejector plate 7 moves, it will drive the ejector column 22 to move together. When the ejector column 22 moves, it will move into the snap-fit ​​box 9 through the inclined first push column 13. When the first push column 13 moves, it will cause the snap-fit ​​block 16 to retract into the fixed column 15 through the second push column 17. In this way, the snap-fit ​​block 16 will separate from the second snap-fit ​​groove 18. The limiting column 5 located outside the fixed column 15 will move to the side of the snap-fit ​​box 9 under the action of the first elastic element 14. In this way, the limiting column 5 will move horizontally under the action of the connecting column 11, and snap-fit ​​the LED light strip 3 onto the mounting frame 2 through its specific L-shaped shape. Then, the snap-fit ​​installation of the LED light strip 3 is completed by the clamping strips 4 on both sides of the mounting frame 2.

[0042] When the LED light strip 3 needs to be replaced, push the two limiting posts 5 towards the middle. When the limiting posts 5 move, they will lose their fixation on the LED light strip 3. At the same time, when the limiting posts 5 move, they will compress the first elastic element 14. Moreover, the second snap-fit ​​groove 18 in the limiting post 5 will re-contact the snap-fit ​​block 16. The snap-fit ​​block 16 releases and drives the ejector post 22 to move upward through the second pushing post 17 and the first pushing post 13. When the ejector post 22 moves upward, it will drive the ejector plate 7 to separate the LED light strip 3 from the mounting frame 2, making it easier to disassemble the LED light strip 3. At the same time, when the ejector post 22 moves, it will drive the piston post 23 to move through the piston chamber 12. When the piston post 23 moves, it will drive the rotating post 24 to rotate through the sliding block 28 and the spiral groove 27. When the rotating post 24 moves, it will drive the limiting block 10 to move downward, so that the snap-fit ​​box 9 loses the restriction of the limiting block 10 and can be disengaged from the first snap-fit ​​groove 6, completing the removal of the snap-fit ​​box 9 and facilitating the replacement of the snap-fit ​​box 9.

[0043] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
