Description

Technical Field

[0001] This utility model belongs to the field of LED technology, and specifically relates to a flexible LED light strip applicable to multiple scenarios based on magnetic fixation. Background Technology

[0002] LED flexible light strips, also known as flexible neon tubes, are the latest and most popular breakthrough LED product. They were developed to overcome the shortcomings of glass neon tubes and optical fibers, thus completely replacing them.

[0003] However, when storing flexible LED light strips, manual winding requires repeated adjustments of force, which can easily lead to the light strip getting tangled and knotted. The fixed installation method is limited, making it difficult to quickly switch between usage scenarios. The overall operation is cumbersome and time-consuming. At the same time, traditional pasting or binding methods can damage the wall surface and are difficult to reuse. When disassembling, adhesive residue is easily left or tools are required. It is impossible to achieve quick positioning and free splicing, resulting in low lighting efficiency.

[0004] To address the issues mentioned above, a flexible LED light strip with magnetic fixation is proposed that is applicable to multiple scenarios. Utility Model Content

[0005] The purpose of this utility model is to provide a flexible LED light strip applicable to multiple scenarios based on magnetic fixation, which has the advantages of automatic winding and magnetic buckle installation.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a flexible LED light strip applicable to multiple scenarios based on magnetic fixation, including a housing, a fixed shaft is bolted to the center of the rear end inside the housing, a coil spring is fixedly sleeved on the rear end of the surface of the fixed shaft, a rotating cylinder is fixedly connected to the end of the coil spring away from the fixed shaft, and the center of the front end and the front end of the surface of the rotating cylinder are rotatably connected to the front of the fixed shaft and the front end of the inner wall of the housing, a light strip is fixedly sleeved on the rear end of the surface of the rotating cylinder, an opening is provided through the rear end of the right side inside the housing, and the left side of the surface of the light strip penetrates the interior of the opening, a baffle is fixedly sleeved in the middle of the surface of the fixed shaft, an anti-winding mechanism is provided at the front end of the top of the fixed shaft, and a magnetic mechanism is provided on the back of the housing.

[0007] Using the above technical solution: When the light strip needs to be pulled out, hold the hook and pull it outwards to move the light strip. The guide wheel guides the light strip, and the movement of the light strip drives the rotating drum to rotate. The rotation of the rotating drum causes the coil spring to stretch, and the rotation of the rotating drum causes the ratchet to rotate. The ratchet rotates in the opposite direction to the pawl engagement. The pawl does not restrict the rotation of the ratchet. When the ratchet rotates, it squeezes the pawl. The pawl causes the spring to contract and rebound. The damper limits the spring. When the light strip is pulled to the designated position, the hook engages and fixes it. The coil spring begins to contract due to the loss of tension. At this time, it drives the ratchet to rotate. The ratchet and pawl engage in the same direction. The pawl restricts the rotation of the ratchet, preventing the coil spring from contracting and winding up. When the power is connected, the light strip lights up. When it needs to be wound up and stored, turn off the power and remove the hook. Hold the lever with your hook and press the lever with your other hand. The lever moves the pawl downwards, causing the spring to contract. The ratchet loses its grip, and the coil spring loses its gripping force. The coil spring contracts, causing the drum to rotate in the opposite direction. The drum then rotates the LED strip to rewind. Once rewinding is complete, release the lever. The spring rebounds, causing the pawl to return to its original position. The press-to-rewind design allows for convenient operation with a simple press. The coil spring provides adaptive winding force, ensuring that LED strips of different lengths can be rewound smoothly. The ratchet anti-rebound mechanism ensures storage stability, while the press-to-unlock function makes the rewinding process easy and controllable. It combines installation flexibility, storage reliability, and operational convenience, making it particularly suitable for retail displays, home décor, and temporary lighting scenarios that require frequent changes in layout.

[0008] The present invention is further configured such that the magnetic attraction mechanism includes a metal block, the metal block is bolted to the center of the back of the outer shell, the surface of the metal block has a slot, a locking rod is locked inside the slot, a magnet is magnetically connected to the back of the metal block, a back plate is embedded in the back of the magnet, and the locking rod passes through the back plate and the inner wall on both sides and slides in a sleeve, a spring is sleeved at the far end of the two locking rod surfaces, and a slider is fixedly sleeved at the near end of the two locking rod surfaces, and a sliding groove is slidably connected to the surface of the slider.

[0009] The above technical solution employs a magnetic attraction mechanism. When fixation is needed, first secure the backpack to the wall. Hold the outer shell and insert the metal block on the back panel. The magnet attracts the metal block, causing it to press against the lever as it enters. The lever moves outward, driving the slider. The slider's movement is limited by the groove, compressing the spring. The magnet attracts the metal block again. When fully inserted, the lever loses its pressure, the spring rebounds, and the slider moves, causing the lever to move inward and engage with the groove. To remove, grasp the handles on both sides and pull them apart, moving the lever. The lever moves the slider, compressing the spring and pulling it outward. This causes the metal block to move, losing its magnetic connection with the magnet. Releasing the handles allows the spring to return to its original position. The snap-on back panel can be flexibly assembled, secured by pressing the magnetic snap-on, and easily removed without falling off. This design is particularly suitable for commercial windows, exhibitions, and smart home scenarios requiring frequent lighting changes.

[0010] The present invention is further configured such that the anti-winding mechanism includes a spring, the spring being bolted to the front end of the top of the fixed shaft, a damper being sleeved inside the spring, a pawl being bolted to the top of the spring, a ratchet groove being provided at the front end of the inner wall of the rotating drum, and the inside of the ratchet groove engaging with the top of the pawl, a lever being bolted to the front of the pawl, and a slot being provided at the top of the front of the rotating drum, with the surface of the lever penetrating through the inside of the slot.

[0011] The above technical solution is adopted as follows: By setting an anti-winding mechanism, the coil spring begins to contract due to loss of tension. At this time, it drives the ratchet to rotate. The ratchet and pawl engage in the same direction. The pawl restricts the rotation of the ratchet, preventing the coil spring from contracting and winding. Pressing the lever causes the pawl to move downward. The spring contracts, the ratchet loses the engagement and fixation of the pawl, and the coil spring loses the engagement force of the pawl. The coil spring contracts and drives the drum to rotate in the opposite direction. The drum drives the light strip to rotate and wind up. After winding is completed, the lever is released, and the spring rebounds and drives the pawl to return to its original position.

[0012] The present invention is further configured such that limit blocks are bolted to both sides of the back of the rotating drum, and a limit groove is formed around the rear end of the outer shell away from the center, and the interior of the limit groove is slidably connected to the surface of the limit block.

[0013] The above technical solution, by setting limit blocks and limit grooves, can limit the rotation of the rotating drum.

[0014] The present invention is further configured such that guide wheels are bolted to the top and bottom of the right side of the outer casing, and the interior of the guide wheels is slidably connected to the right side of the surface of the light strip.

[0015] The above technical solution uses guide wheels to guide the pulling out and rewinding of the light strip.

[0016] The present invention is further configured such that a hook is fixedly sleeved at the end of the light strip away from the rotating drum.

[0017] The above technical solution allows for easy pulling and fixing of the light strip by incorporating hooks.

[0018] The present invention is further configured such that a handle is fixedly sleeved at the far end of the two clamps.

[0019] The above technical solution allows for easy pulling of the lever by incorporating a handle.

[0020] The present invention is further configured such that the periphery of the front side of the outer casing away from the center is provided as a transparent plate.

[0021] The above technical solution allows the light strip to be stored inside the housing and turned on by setting it as a transparent plate.

[0022] In summary, this utility model has the following beneficial effects:

[0023] 1. This utility model achieves convenient operation of one-click retraction through a press-type ratchet separation design.

[0032] The present invention will be further described in detail below with reference to the accompanying drawings.

[0033] Example 1:

[0034] refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6A flexible LED light strip applicable to multiple scenarios based on magnetic fixation includes a housing 1. A fixed shaft 2 is bolted to the center of the rear end inside the housing 1. A coil spring 3 is fixedly sleeved on the rear end of the surface of the fixed shaft 2. A rotating drum 4 is fixedly connected to the end of the coil spring 3 away from the fixed shaft 2. The center of the front end and the front end of the surface of the rotating drum 4 are rotatably connected to the front of the fixed shaft 2 and the front end of the inner wall of the housing 1. A light strip 5 is fixedly sleeved on the rear end of the surface of the rotating drum 4. An opening 6 is provided through the rear end of the right side inside the housing 1, and the left side of the surface of the light strip 5 is provided through the opening 6. A baffle 7 is fixedly sleeved in the middle of the surface of the fixed shaft 2. An anti-winding mechanism is provided at the front end of the top of the fixed shaft 2. A magnetic attraction mechanism is provided on the back of the housing 1. When the light strip 5 needs to be pulled out, the hook 25 is grasped and pulled outward, which moves the light strip 5. The guide wheel 24 guides the light strip 5. The movement of the light strip 5 causes the rotating drum 4 to rotate. The rotation of the rotating drum 4 causes the coil spring 3 to stretch. The rotation of the rotating drum 4 causes the ratchet 19 to rotate. The rotation of the ratchet 19 engages with the pawl 18 in the same direction. The anti-ratchet 18 does not restrict the rotation of the ratchet 19. When the ratchet 19 rotates, it compresses the pawl 18, causing the spring 13 to contract and rebound. The damper 17 limits the spring 13. When the light strip 5 is pulled to the designated position, the hook 25 engages and fixes it. The coil spring 3 begins to contract due to loss of tension, which in turn causes the ratchet 19 to rotate. The ratchet 19 and the pawl 18 engage in the same direction. The pawl 18 restricts the rotation of the ratchet 19, preventing the coil spring 3 from contracting and winding. When the power is connected, the light strip 5 lights up. When winding is required, the light strip is retracted. When using the device, turn off the power, remove the hook 25 and hold it in the hooked position. Press the lever 20 with your other hand. The lever 20 causes the pawl 18 to move downwards and the spring 13 to retract. The ratchet groove 19 loses the locking and fixing of the pawl 18, and the coil spring 3 loses the locking force of the pawl 18. The coil spring 3 retracts and causes the rotating drum 4 to rotate in the opposite direction. The rotating drum 4 causes the light strip 5 to rotate and rewind. After winding is completed, release the lever 20. The spring 13 rebounds and causes the pawl 18 to return to its original position. The press-type pawl 18 separation design realizes the convenient operation of rewinding with one press.

[0035] refer to Figure 1 , Figure 3 , Figure 4The anti-winding mechanism includes a spring 13, which is bolted to the front end of the fixed shaft 2. A damper 17 is sleeved inside the spring 13, and a pawl 18 is bolted to the top of the spring 13. A ratchet groove 19 is provided at the front end of the inner wall of the rotating drum 4, and the inside of the ratchet groove 19 engages with the top of the pawl 18. A lever 20 is bolted to the front of the pawl 18. A slot 21 is opened at the top of the front of the rotating drum 4, and the surface of the lever 20 penetrates the inside of the slot 21. By setting up the anti-winding mechanism, the coil spring 3 loses its tension and opens... When the coil starts to contract, it causes the ratchet 19 to rotate. The ratchet 19 and the pawl 18 engage in the same direction. The pawl 18 restricts the rotation of the ratchet 19, preventing the coil spring 3 from contracting and winding. Pressing the lever 20 causes the pawl 18 to move downwards, and the spring 13 contracts. The ratchet 19 loses the engagement and fixation of the pawl 18, and the coil spring 3 loses the engagement force of the pawl 18. The coil spring 3 contracts, causing the rotating drum 4 to rotate in the opposite direction. The rotating drum 4 causes the light strip 5 to rotate and wind up. After winding is completed, the lever 20 is released, and the spring 13 rebounds, causing the pawl 18 to return to its original position.

[0036] refer to Figure 6 Limiting blocks 22 are bolted to both sides of the back of the rotating drum 4. A limiting groove 23 is opened around the rear end of the outer shell 1 away from the center. The inside of the limiting groove 23 is slidably connected to the surface of the limiting block 22. By setting the limiting block 22 and the limiting groove 23, the rotation of the rotating drum 4 can be limited.

[0037] refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 Guide wheels 24 are bolted to the top and bottom of the right side of the outer casing 1, and the inside of the guide wheels 24 is slidably connected to the right side of the surface of the light strip 5. By setting the guide wheels 24, the pulling out and winding of the light strip 5 can be guided.

[0038] refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 A hook 25 is fixedly attached to the end of the light strip 5 away from the rotating drum 4. By setting the hook 25, the light strip 5 can be easily pulled and fixed.

[0039] refer to Figure 1 The front of the outer casing 1 is surrounded by a transparent panel away from the center. By making it transparent, the light strip 5 can be stored inside the outer casing 1 and turned on.

[0040] Brief description of usage: When the light strip 5 needs to be pulled out, grasp the hook 25 and pull it outwards, causing the light strip 5 to move. The guide wheel 24 guides the light strip 5. The movement of the light strip 5 causes the rotating drum 4 to rotate. The limiting block 22 and the limiting groove 23 limit the rotation of the rotating drum 4. The rotation of the rotating drum 4 causes the coil spring 3 to stretch. The rotation of the rotating drum 4 causes the ratchet 19 to rotate. The rotation of the ratchet 19 is opposite to the engagement direction of the pawl 18. The pawl 18 does not restrict the rotation of the ratchet 19. When the ratchet 19 rotates, it squeezes the pawl 18. The pawl 18 causes the spring 13 to contract and rebound. The damper 17 limits the spring 13. When the light strip 5 is pulled to the designated position, the hook 25 is hooked and fixed. The coil spring 3 begins to contract due to the loss of tension. At this time, the ratchet 19 is pulled outwards. When the groove 19 rotates, the groove 19 and the pawl 18 engage in the same direction. The pawl 18 restricts the rotation of the groove 19, preventing the coil spring 3 from retracting and winding. When the power is connected, the light strip 5 lights up. When it is time to wind up and store, turn off the power, remove the hook 25 and hold it in place. Press the lever 20 with your other hand. The lever 20 moves the pawl 18 downward and the spring 13 retracts. The groove 19 loses the engagement and fixation of the pawl 18, and the coil spring 3 loses the engagement force of the pawl 18. The coil spring 3 retracts and drives the rotating drum 4 to rotate in the opposite direction. The rotating drum 4 drives the light strip 5 to rotate and wind up. After winding up, release the lever 20. The spring 13 rebounds and drives the pawl 18 to return to its original position. The press-type pawl 18 separation design realizes the convenient operation of one-press winding.

[0041] Example 2:

[0042] refer to Figure 4 , Figure 5A flexible LED light strip applicable to multiple scenarios based on magnetic fixation is disclosed. The magnetic mechanism includes a metal block 8, which is bolted to the center of the back of the outer shell 1. A slot 9 is formed on the surface of the metal block 8, and a locking rod 10 is locked inside the slot 9. A magnet 11 is magnetically connected to the back of the metal block 8, and a back plate 12 is embedded in the back of the magnet 11. The locking rod 10 passes through the back plate 12 and the inner wall on both sides and slides in a sleeve. A spring 14 is sleeved at the far end of the two locking rods 10, and a slider 15 is fixedly sleeved at the near end of the two locking rods 10. A groove 16 is slidably connected to the surface of the slider 15. When fixation is required, first fix the backpack to the wall, hold the outer shell 1, insert the metal block 8 on the back of the outer shell 1 into the back plate 12, and the magnet 11 magnetically attracts the metal block 8, causing the metal block 8 to enter the back plate 12. When the lever 10 is pressed, it moves outward, causing the slider 15 to move. The slide groove 16 limits the movement of the slider 15. The movement of the slider 15 compresses and contracts the second spring 14. The magnet 11 magnetically attracts the metal block 8. When fully inserted, the lever 10 loses its compressive force, and the second spring 14 rebounds, causing the slider 15 to move. The slider 15 then moves the lever 10, causing it to move inward and engage with the slot 9. To remove it, grasp the handles 26 on both sides and pull them apart, causing the lever 10 to move. The lever 10 then moves the slider 15, which compresses and contracts the second spring 14, pulling the outer shell 1 outward and causing the metal block 8 to move. The metal block 8 loses its magnetic connection with the magnet 11. Release the handles 26, and the second spring 14 rebounds, causing the mechanism to return to its original state.

[0043] refer to Figure 4 A handle 26 is fixedly sleeved at the far end of the two levers 10, which makes it easy to pull the levers 10.

[0044] Brief description of usage: When fixation is required, first secure the backpack to the wall. Hold the outer shell 1 and insert the metal block 8 on the back of the outer shell 1 into the back panel 12. The magnet 11 magnetically attracts the metal block 8. When the metal block 8 enters, it compresses the lever 10, causing the lever 10 to move outward. The lever 10 drives the slider 15 to move, and the slide groove 16 limits the movement of the slider 15. The movement of the slider 15 compresses and contracts the spring 14, and the magnet 11 magnetically attracts the metal block 8. When fully inserted, the lever 10 releases its compression. The force of the spring 14 causes the slider 15 to move, which in turn causes the locking rod 10 to move. The locking rod 10 moves inward and engages with the slot 9. When it needs to be removed, hold the handles 26 on both sides and pull them apart. This causes the locking rod 10 to move, which in turn causes the slider 15 to move. The slider 15 compresses and contracts the spring 14, pulling the outer shell 1 outward and causing the metal block 8 to move. The metal block 8 loses its magnetic connection with the magnet 11. Release the handles 26, and the spring 14 returns, causing the mechanism to return to its original state.
