Description

Technical Field

[0001] This utility model relates to the field of LED strip technology, and more specifically, to a cuttable and splicable LED strip. Background Technology

[0002] In existing technologies, the connection method of cuttable and spliced ​​light strips has some significant drawbacks. These drawbacks not only affect the convenience of the installation process, but may also lead to unstable connections after splicing. In traditional spliced ​​light strip designs, the connection and installation process is usually cumbersome and not intuitive. Many light strip designs use manual docking methods, which usually rely on mechanical connection parts such as plugs, clips, or screws. The operation steps are relatively complicated and require a high level of technical skills from the operators. During the installation process, users must accurately align each connection point, otherwise it may lead to loose connections or installation failure.

[0003] Even after splicing, traditional cuttable and splicable light strips often suffer from unstable connections, which may affect the long-term performance and safety of the light strips. Because the snap-fit ​​or insertion design of traditional connection methods is easily affected by external forces or vibrations, the spliced ​​light strips may experience loose connections. Especially after the light strips are installed, during long-term use, vibrations from the external environment may cause the connection points to gradually loosen, resulting in poor contact of the light strips or even shutdown. Sometimes, the light strips may shift position after splicing, especially when splicing multiple light strips. Loosening of some connection points may lead to uneven distribution of the light strips, which not only affects the lighting effect but may also damage the aesthetics and practicality of the light strips.

[0029] Please see Figures 1-5A cuttable and splicable LED light strip includes grouped light strips 1, a splicing and snapping mechanism, a stabilizing rotation mechanism, and a locking mechanism. The splicing and snapping mechanism includes a snapping rod 2, a snapping tube 3, a rotating sleeve 4, a rotary push block 5, an annular groove 6, a compression spring rod 7, and a pressing groove 8. The snapping tube 3 is installed on one grouped light strip 1 and another grouped light strip 1. The snapping rod 2 can extend into the interior of the snapping tube 3 to connect the two grouped light strips 1. The rotating sleeve 4 is rotatably mounted on the outer wall of the snapping tube 3. The rotary push block 5 is rotatably mounted on the inner wall of the rotating sleeve 4. The annular groove 6 is provided on the side wall of the snapping rod 2. 5 can extend into the annular groove 6. The spring rod 12 is installed at the top end of the annular groove 6. The pressing groove 8 is set at the top end of the rotary push block 5. The spring rod 12 can extend into the pressing groove 8 to fix the rotary push block 5 in the annular groove 6. The stable rotation mechanism includes a rail block 9, a fixing ring 10, a mating hole 11 and a spring rod 12. The rail block 9 is installed at the bottom end of the rotating sleeve 4. The fixing ring 10 is fixedly installed on the outer wall of the clamping tube 3. Multiple sets of mating holes 11 are arranged in annularly on the fixing ring 10. The spring rod 12 is installed on the rail block 9. When the spring rod 12 extends into the mating groove step by step, the rail block 9 and the rotating sleeve 4 are stably locked and rotated step by step.

[0030] In this embodiment, the splicing and snapping mechanism achieves a reliable connection of the grouped light strips 1. The two grouped light strips 1 are connected through the snap-fit ​​tube 3 and snap-fit ​​rod 2 on the longitudinal plate 19. The snap-fit ​​rod 2 passes through the adjacent longitudinal plate 19 and extends into the snap-fit ​​tube 3. The annular groove 6 on its side wall cooperates with the rotary push block 5 on the inner wall of the rotating sleeve 4. The rotary push block 5 can extend into the annular groove 6 under the action of the rotary push spring 23. The compression spring rod 7 extends from the top of the annular groove 6 into the pressing groove 8 of the rotary push block 5, forming a double lock. When it is necessary to separate, the reverse rotation is performed. The sleeve 4 is rotated so that the open end of the side wall of the retaining tube 3 is pressed against the rotary push block 5, causing it to retract into the block groove 22, thus releasing the lock. The rail block 9 at the bottom of the rotating sleeve 4 and the multiple sets of mating holes 11 on the outer wall fixing ring 10 of the retaining tube 3 form a step-by-step locking mechanism. The spring rod 12 on the rail block 9 can extend into the mating holes 11 in sequence, allowing the rotating sleeve 4 to rotate stably step by step. The bottom of the rail block 9 cooperates with the track 24 at the top of the connecting plate 20 to provide rotation guidance, ensuring the accuracy of the movement trajectory and making the light strip connection process more controllable and precise. When the locking mechanism needs to work, the locking mechanism provides additional rotational fixing protection. The outer rotating ring 13 on the outer wall of the retaining tube 3 meshes with the rotating tooth 15 through the outer toothed ring 14 at the bottom. The rotating tooth 15 is connected to the threaded rod 16, which is in turn threadedly connected to the longitudinal ring 17.

[0031] The locking mechanism includes an outer rotating ring 13, an outer toothed ring 14, a rotating tooth 15, a threaded rod 16, a longitudinal ring 17, and a rubber pad 18. The outer rotating ring 13 is rotatably mounted on the outer wall of the retaining tube 3. The outer toothed ring 14 is mounted on the bottom end of the outer rotating ring 13 and is meshed with the rotating tooth 15. One end of the threaded rod 16 is connected to the rotating tooth 15. The longitudinal ring 17 is longitudinally slidably mounted on the outer wall of the retaining tube 3 and is threadedly connected to the threaded rod 16. The rubber pad 18 is mounted on the bottom end of the longitudinal ring 17 and can be pressed against the top end of the rotating sleeve 4 to fix the rotating sleeve 4 in the rotation direction.

[0032] In this embodiment, when the threaded rod 16 is adjusted, the longitudinal ring 17 can be moved up and down. The rubber pad 18 at the bottom of the longitudinal ring 17 can press against the top of the rotating sleeve 4, and the rotating sleeve 4 is fixed in the rotation direction by friction to prevent accidental loosening. The support plate 21 provides stable support for the rotating tooth 15 to ensure the reliability of the meshing transmission. When the threaded ring releases the rotating sleeve 4 from the fixation, the rotating sleeve 4 is rotated in the opposite direction to make the rotary push block 5 move away from the slot, thereby disconnecting the adjacent longitudinal plates 19.

[0033] Please see Figures 1-5 As a supplementary embodiment of the cuttable splicing LED light strip for the splicing snap-fit ​​mechanism, stabilizing rotation mechanism, and locking mechanism: Longitudinal plates 19 are installed at both ends of the grouped light strip 1, and a connecting plate 20 is installed at the bottom of the side wall of the snap-fit ​​tube 3. The connecting plate 20 is fixedly installed at the top end of the longitudinal plates 19. One end of the snap-fit ​​rod 2 can pass through the adjacent longitudinal plates 19 and extend into the interior of the snap-fit ​​tube 3 to engage and snap together, connecting the connected grouped light strips 1. A support plate 21 is installed on the outer wall of the snap-fit ​​tube 3, and a rotating tooth 15 is rotatably mounted on the support plate 21. On the top end face of 1, the inner wall of the rotating sleeve 4 is provided with a block groove 22, and the rotating push block 5 is rotatably installed in the block groove 22. When the rotating sleeve 4 is rotated in different directions, one end of the side wall opening of the clamping pipe 3 can be pressed against the rotating push block 5 and retracted into the block groove 22. One end of the rotating push block 5 is provided with a rotating push spring 23, and the other end of the rotating push spring 23 is in contact with the inner wall of the block groove 22 for support. The rotating push spring 23 can push the rotating push block 5 into the annular groove 6. The top end of the connecting plate 20 is provided with a track 24, and the bottom end of the track block 9 is rotated and guided in cooperation with the track 24.

[0034] More specifically, the user connects two grouped light strips 1 using a snap-fit ​​rod 2. First, the snap-fit ​​rod 2 extends into one snap-fit ​​tube 3, and then the other end extends into the other snap-fit ​​tube 3, connecting the two grouped light strips 1 into a complete light strip. Through the rotation of the rotating sleeve 4, the push block 5 inside the rotating sleeve 4 engages with the annular groove 6 of the snap-fit ​​rod 2. During rotation, the push block 5 is locked in the annular groove 6 by the spring rod 12, thus securing the connection. During the rotation of the rotating sleeve 4, the rail block 9 interacts with the mating hole 11 on the fixing ring 10, and the spring rod 12 gradually extends into the mating hole 11, stabilizing the connection. Locking the rotating sleeve 4 prevents loosening during rotation. Through the meshing of the outer rotating ring 13 and the outer toothed ring 14, the rotating tooth 15 cooperates with the threaded rod 16. When the longitudinal ring 17 slides, the rubber pad 18 presses against the top end of the rotating sleeve 4 to ensure that the rotating sleeve 4 and the splicing connection part are stably fixed and prevent loosening. After the entire process is completed, the light strip is firmly connected and in the predetermined position, and can maintain a stable connection during long-term use, avoiding position changes due to vibration, external force and other factors. When the threaded ring releases the fixing of the rotating sleeve 4, the rotating sleeve 4 gains rotational freedom, realizing the disconnection of the adjacent longitudinal plate 19.

[0035] In summary, when the overall equipment is in use or operation: when the splicing and snapping mechanism is required, the splicing and snapping mechanism achieves a reliable connection of the grouped light strips 1. The two grouped light strips 1 are connected through the snap-fit ​​tube 3 and snap-fit ​​rod 2 on the longitudinal plate 19. The snap-fit ​​rod 2 passes through the adjacent longitudinal plate 19 and extends into the inside of the snap-fit ​​tube 3. The annular groove 6 on its side wall cooperates with the rotary push block 5 on the inner wall of the rotating sleeve 4. Under the action of the rotary push spring 23, the rotary push block 5 can extend into the annular groove 6. The compression spring rod 7 extends from the top of the annular groove 6 into the pressing groove 8 of the rotary push block 5, forming a double lock. When it is necessary to separate, rotate the rotating sleeve 4 in the opposite direction, so that the open end of the side wall of the snap-fit ​​tube 3 presses against the rotary push block 5, so that it retracts into the block groove 22, and the lock can be released.

[0036] When the rotating mechanism needs to be operated stably, the rail block 9 at the bottom of the rotating sleeve 4 and the multiple sets of mating holes 11 on the outer wall fixing ring 10 of the clamping pipe 3 form a step-by-step locking mechanism. The spring rod 12 on the rail block 9 can be inserted into the mating holes 11 in sequence, so that the rotating sleeve 4 can rotate stably step by step. The bottom of the rail block 9 cooperates with the track 24 on the top of the connecting plate 20 to provide rotation guidance, ensure the accuracy of the motion trajectory, and make the light strip connection process more controllable and precise.

[0037] When the locking mechanism is required to operate, it provides additional rotational fixation protection. The outer rotating ring 13 on the outer wall of the retaining tube 3 engages with the rotating tooth 15 through the outer toothed ring 14 at the bottom. The rotating tooth 15 is connected to the threaded rod 16, which in turn is threadedly connected to the longitudinal ring 17. When the threaded rod 16 is adjusted, the longitudinal ring 17 can be moved up and down. The rubber pad 18 at the bottom of the longitudinal ring 17 can press against the top of the rotating sleeve 4, fixing the rotating sleeve 4 in the rotational direction through friction to prevent accidental loosening. The support plate 21 provides stable support for the rotating tooth 15, ensuring the reliability of the meshing transmission. When the threaded ring releases the rotating sleeve 4 from its fixation, the rotating sleeve 4 is rotated in the opposite direction, causing the rotary push block 5 to move away from the retaining groove, thereby disengaging the adjacent longitudinal plates 19.

[0038] The user connects two grouped light strips 1 using a snap-fit ​​rod 2. First, the snap-fit ​​rod 2 extends into one snap-fit ​​tube 3, and then the other end extends into the other snap-fit ​​tube 3, connecting the two grouped light strips 1 into a complete light strip. As the rotating sleeve 4 rotates, the push block 5 inside the rotating sleeve 4 engages with the annular groove 6 of the snap-fit ​​rod 2. During rotation, the push block 5 is locked in the annular groove 6 by the spring rod 12, thus securing the connection. During the rotation of the rotating sleeve 4, the rail block 9 interacts with the mating hole 11 on the fixing ring 10, and the spring rod 12 extends into the mating hole 11 step by step, stably locking the rotating sleeve. The rotating sleeve 4 prevents loosening during rotation. Through the meshing of the outer rotating ring 13 and the outer toothed ring 14, the rotating tooth 15 cooperates with the threaded rod 16. When the longitudinal ring 17 slides, the rubber pad 18 presses against the top end of the rotating sleeve 4 to ensure that the rotating sleeve 4 and the splicing connection part are stably fixed and prevent loosening. After the entire process is completed, the light strip is firmly connected and in the predetermined position, and can maintain a stable connection during long-term use, avoiding position changes caused by vibration, external force and other factors. When the threaded ring releases the fixing of the rotating sleeve 4, the rotating sleeve 4 gains rotational freedom, realizing the disconnection of the adjacent longitudinal plate 19.

[0039] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
