[0002] LED light strips are linear lighting devices made by integrating multiple LED beads at specific intervals on an insulating substrate, along with wires, driving circuits, and an outer protective structure. They are typically available in flexible or rigid forms and can be spliced ​​into multiple sections using connectors and fixing components. They can be cut or bent according to usage requirements and are widely used in indoor decorative lighting, outdoor landscape lighting, equipment indicator lights, and other scenarios. They are characterized by low energy consumption, long lifespan, uniform light emission, and convenient installation. Some high-performance models also enhance waterproof, shockproof, and high-temperature resistance properties to adapt to complex environments. However, ordinary LED light strips are prone to problems such as loose splicing, protection failure, and poor adaptability in complex scenarios such as vibration, humidity, and irregular installation. They cannot meet the high requirements of outdoor, automotive, and industrial equipment applications for structural stability, environmental tolerance, and long-term reliability. Therefore, a highly stable LED light strip is particularly needed.

[0021] 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.

[0022] Please see Figure 1-6This utility model provides a technical solution: a high-stability LED light strip, including a fixing base 1, an LED light strip 2 installed inside the fixing base 1, a connector 3 installed on one side of the LED light strip 2, a sealing gasket 4 connecting the fixing base 1 and the LED light strip 2, a positioning device 5 provided between the fixing base 1 and the LED light strip 2, and a fixing device 6 provided on the surface of the positioning device 5.

[0023] The fixing device 6 includes a fixing hole 601, which is formed on the surfaces of the positioning device 5 and the fixing base 1. A stop groove 602 is formed on the upper outer side of the fixing hole 601. A screw 603 is connected through the inside of the fixing hole 601. A connecting rod 604 is connected to the top of the screw 603. A sliding groove 605 is formed on the side of the connecting rod 604. A stop ratchet 606 is slidably connected to the outer wall of the connecting rod 604. A slider 607 is connected to the inner side of the stop ratchet 606. The slider 607 slides with the sliding groove 605. A nut 608 is connected to the top of the connecting rod 604. The upper surface of the stop ratchet 606 extends to the nut 608 and passes through the nut 608 to connect to a vertical pull rod 609. A compression spring 610 is connected to the bottom outer side of the rod 609. A limit plate 611 is connected to the top of the vertical pull rod 609. A horizontal pull rod 612 is connected to the side of the limit plate 611. With the setting of the fixing device 6, firstly, the operator aligns the screw 603 with the fixing hole 601 preset on the surface of the positioning device 5 and the fixing seat 1, and inserts the screw 603 through the fixing hole 601. At this time, the connecting rod 604 at the top of the screw 603 protrudes above the fixing hole 601. Next, the stop ratchet 606 is sleeved on the outer wall of the connecting rod 604, so that the slider 607 on the inner side of the stop ratchet 606 is embedded in the slide groove 605 on the side of the connecting rod 604, ensuring that the stop ratchet 606 can slide up and down along the slide groove 605 but cannot be connected relative to the target. Rotate the connecting rod 604, then screw the nut 608 onto the top of the connecting rod 604. When rotating the nut 608 clockwise, the nut 608 drives the connecting rod 604 and the screw 603 to rotate synchronously, causing the screw 603 to gradually screw into the fixing hole 601. At the same time, the stop ratchet 606 gradually approaches the stop groove 602 above the fixing hole 601 as the nut 608 is pressed down, until the teeth of the stop ratchet 606 contact the inner wall of the stop groove 602. Continue to tighten the nut 608. When the screw 603 is fully tightened and the LED light strip 2 and the fixing seat 1 are firmly attached by the positioning device 5, stop rotating the nut 608. At this time, the operator releases the pull on the vertical pull rod 609, and the compression spring 610 releases its elasticity. Potential energy pushes the vertical pull rod 609 downward to reset. The vertical pull rod 609 drives the stop ratchet 606 to slide downward along the slide groove 605, so that the teeth of the stop ratchet 606 are fully embedded in the stop groove 602. Through the one-way meshing of the stop ratchet 606 and the stop groove 602, the reverse rotation of the screw 603 and the nut 608 is restricted, preventing the screw 603 from loosening due to long-term vibration. If disassembly or adjustment is required later, the operator can pull the limit plate 611 through the horizontal pull rod 612, which drives the vertical pull rod 609 to lift the stop ratchet 606 upward, so that the teeth of the stop ratchet 606 disengage from the stop groove 602. Then the nut 608 can be rotated in the opposite direction to remove the screw 603, completing the unlocking operation of the fixing device 6.

[0024] Furthermore, the side of the mounting base 1 is provided with a plug-in groove, and the plug-in 3 is connected to the LED light strip 2 through the plug-in groove. The setting of the plug-in groove and the plug-in 3 can, on the one hand, provide precise positioning for the connection between the plug-in 3 and the LED light strip 2, avoid the plug-in 3 from being misaligned during installation and causing poor contact, and ensure the stable circuit connection of the LED light strip 2. On the other hand, the plug-in groove can form a wrap-around protection for the plug-in 3, reducing the direct contact of external dust and moisture with the metal contacts of the plug-in 3. Together with the sealing gasket 4 between the mounting base 1 and the LED light strip 2, it can further improve the overall protection performance. At the same time, when the LED light strip 2 is pulled by external force, the plug-in groove can restrict the displacement of the plug-in 3, prevent the plug-in 3 from falling off the LED light strip 2, and ensure the long-term stable operation of the LED light strip 2.

[0025] Furthermore, the positioning device 5 includes a mounting groove 501, which is formed inside the fixed base 1. The LED light strip 2 is installed inside the mounting groove 501. Locking blocks 502 are connected to both sides of the LED light strip 2. Locking slots 503 are formed on both sides of the mounting groove 501. The locking blocks 502 engage with the locking slots 503. A positioning groove 504 is formed inside the locking blocks 502. A return spring 505 is connected to the inner end of the positioning groove 504. A connecting plate 506 is connected to the other end of the return spring 505. A positioning block 507 is connected to the outer side of the connecting plate 506. A positioning groove 507 is formed on the inner side of the locking slot 503. Positioning holes 508 and fixing holes 601 are formed on the surface of the locking block 502. Through the positioning device, the LED strip 2 is first aligned with the pre-set mounting groove 501 inside the fixing base 1. The LED strip 2 is pushed along the length of the mounting groove 501. During this pushing process, the locking blocks 502 on both sides of the LED strip 2 contact the locking slots 503 on both sides of the mounting groove 501. The inner wall of the locking slot 503 presses against the positioning block 507 on the outside of the locking block 502, causing the positioning block 507 to retract into the positioning groove 504 inside the locking block 502. The positioning block 507 drives the connecting plate 506 to move synchronously, compressing the connecting plate 506. The return spring 505 at the inner end of the positioning groove 504 is compressed and stores elastic potential energy, continuing to push the LED light strip 2 until the locking block 502 is fully embedded in the slot 503. At this time, the positioning block 507 inside the locking block 502 is precisely aligned with the positioning hole 508 on the inner side of the slot 503. The return spring 505 releases its elastic potential energy, pushing the connecting plate 506 to move towards the positioning hole 508. The connecting plate 506 drives the positioning block 507 to extend out of the positioning groove 504 and embed into the positioning hole 508. Through the engagement of the positioning block 507 and the positioning hole 508, the locking block 502 is restricted from moving. The movement within the slot 503 enables the LED strip 2 to be initially positioned and fixed within the mounting slot 501. Simultaneously, the fixing holes 601 on the surface of the card block 502 are precisely aligned with the fixing holes 601 on the surface of the fixing base 1, providing a positioning basis for the subsequent through connection of the screw 603 of the fixing device 6. This ensures that the fixing device 6 can stably lock the positioning device 5 and the fixing base 1, further enhancing the installation stability of the LED strip 2. Moreover, the positioning process requires no additional tools, making operation convenient. It also prevents the LED strip 2 from shifting within the fixing base 1, ensuring that the sealing gasket 4 can be evenly fitted, thus improving the overall sealing effect.

[0026] Furthermore, the LED light strip 2 is installed inside the mounting groove 501 via the locking block 502 and the locking groove 503. The outer wall size of the LED light strip 2 matches the inner wall size of the mounting groove 501, and the sizes of the locking block 502 and the locking groove 503 are precisely matched. Through the setting of the mounting groove 501, the locking block 502 and the locking groove 503, the outer wall size of the LED light strip 2 matches the inner wall size of the mounting groove 501, and the locking block 502 and the locking groove 503 are precisely matched. This not only provides accurate installation positioning for the LED light strip 2 and avoids lateral or longitudinal displacement of the LED light strip 2 in the mounting groove 501, but also restricts the vertical displacement of the LED light strip 2 through the locking of the locking block 502 and the locking groove 503. At the same time, the tight size fit reduces the gap between the LED light strip 2 and the fixing seat 1, creating conditions for the uniform adhesion of the sealing gasket 4, further improving the sealing and stability of the overall structure, and preventing external impurities from entering or the LED light strip 2 from loosening.

[0027] Furthermore, the connecting plate 506, through the cooperation of the return spring 505 and the positioning block 507, forms a telescopic structure. The end of the positioning block 507 away from the connecting plate 506 is chamfered. The outer wall size of the positioning block 507 is precisely matched with the inner wall size of the positioning hole 508. Through the arrangement of the return spring 505, connecting plate 506, positioning block 507, and positioning hole 508, the telescopic structure formed by the connecting plate 506, return spring 505, and positioning block 507, combined with the chamfered design of the positioning block 507, allows the LED... When the LED strip 2 is installed, the positioning block 507 can automatically retract, and the initial engagement can be completed without additional operation. The precise fit between the positioning block 507 and the positioning hole 508 can achieve accurate locking after the LED strip 2 is installed in place, restricting the movement of the locking block 502 in the slot 503, enhancing the initial fixing effect of the LED strip 2. In addition, the elasticity of the return spring 505 can ensure that the positioning block 507 is always tightly embedded in the positioning hole 508, avoiding positioning failure due to vibration during long-term use, and ensuring the stability of the LED strip 2 installation.

[0028] Furthermore, the stop ratchet 606 slides on the surface of the connecting rod 604 via the slider 607 and the groove 605. The outer wall size of the stop ratchet 606 matches the inner wall size of the stop groove 602. Through the arrangement of the stop groove 602, the connecting rod 604, the groove 605, the stop ratchet 606, and the slider 607, the stop ratchet 606 slides along the groove 605 of the connecting rod 604 via the slider 607. This ensures that the stop ratchet 606 moves synchronously with the rotation of the nut 608, while also restricting the rotation of the stop ratchet 606 itself, ensuring that its teeth are always aligned with the stop groove 602. The dimensions of the stop ratchet 606 and the stop groove 602 match. When the stop ratchet 606 is embedded in the stop groove 602, it can restrict the reverse rotation of the screw 603 and the nut 608 through one-way meshing, effectively preventing the fixing device 6 from loosening due to vibration, and providing a guarantee for the long-term stable installation of the LED light strip 2.

[0029] Furthermore, two identical sets of vertical pull rods 609 are symmetrically arranged on the surface of the stop ratchet 606. Compression springs 610 are sleeved on the outside of the vertical pull rods 609, with one end fixedly connected to the upper surface of the stop ratchet 606 and the other end fixedly connected to the bottom surface of the nut 608. Through the arrangement of the vertical pull rods 609 and the compression springs 610, the two sets of symmetrically distributed vertical pull rods 609, together with the outer compression springs 610, with both ends of the compression springs 610 fixed to the stop ratchet 606 and the nut 608 respectively, can provide a continuous downward elastic force to the stop ratchet 606 when the fixing device 6 is locked, ensuring that the stop ratchet 606 is tightly embedded in the stop groove 602 and preventing the teeth from disengaging and causing the stop to fail; and when unlocking is required, by pulling the vertical pull rods 609 to compress the springs 610, the stop ratchet 606 can be driven out of the stop groove 602, realizing convenient unlocking, taking into account both fixing stability and operation convenience.

[0030] Working principle: First, the LED light strip 2 is initially positioned and installed on the mounting base 1. The LED light strip 2 is aligned with the mounting groove 501 inside the mounting base 1. The LED light strip 2 is pushed along the length of the mounting groove 501, and the locking blocks 502 on both sides of the LED light strip 2 contact the locking slots 503 on both sides of the mounting groove 501. The inner wall of the locking slot 503 presses the positioning block 507 on the outer side of the locking block 502, causing the positioning block 507 to retract into the positioning groove 504. This causes the connecting plate 506 to compress the return spring 505 and store elastic potential energy. When the locking block 502 is fully embedded in the locking slot 503, the positioning block 507 is precisely aligned with the positioning hole 508 on the inner side of the locking slot 503. The return spring 505 releases its potential energy to push the positioning block 507 into the positioning hole 508, completing the initial positioning of the LED light strip 2. At this position, the outer wall of the LED strip 2 is tightly fitted with the inner wall of the mounting groove 501, creating uniform contact conditions for the sealing gasket 4 between the fixing seat 1 and the LED strip 2, improving the initial sealing performance. Simultaneously, the fixing holes 601 on the surface of the clip 502 are aligned with the fixing holes 601 on the surface of the fixing seat 1, laying the foundation for the installation of the fixing device 6. Then, the fixing device 6 securely locks the LED strip 2 to the fixing seat 1. The operator inserts the screw 603 through the aligned fixing holes 601, so that the connecting rod 604 at the top of the screw 603 protrudes above the fixing holes 601. The stop ratchet 606 is fitted onto the outer wall of the connecting rod 604, and its inner slider 607 is embedded in the groove 605 of the connecting rod 604, ensuring that the stop ratchet 606 can slide along the groove 605. Unable to rotate, the nut 608 is then tightened and rotated clockwise. The nut 608 drives the connecting rod 604 and the screw 603 to simultaneously screw into the fixing hole 601. The stop ratchet 606 gradually approaches the stop groove 602 as the nut 608 is pressed down, until the screw 603 is fully tightened and the LED light strip 2 is firmly attached to the fixing seat 1. At this time, the previously pulled vertical pull rod 609 is released. The compression spring 610 on the outside of the vertical pull rod 609 releases its elastic potential energy, pushing the vertical pull rod 609 to drive the stop ratchet 606 to slide downward, so that the teeth of the stop ratchet 606 are fully embedded in the stop groove 602. Through one-way meshing, the screw 603 and the nut 608 are restricted to rotate in opposite directions to prevent vibration from causing loosening. Finally, the circuit connection and protection are completed. The LED light strip 2 is then... The connector 3 connects to the external circuit through the connector slot on the side of the fixing base 1. The connector slot provides precise positioning for the connector 3, avoiding poor contact, and also forms a protective enclosure for the connector 3, reducing dust and moisture contact with the metal contacts. Combined with the sealing gasket 4, this further enhances the overall protective performance. If disassembly and adjustment are required later, the horizontal pull rod 612 pulls the limiting plate 611, causing the vertical pull rod 609 to lift the stop ratchet 606 out of the stop groove 602. Rotating the nut 608 in the opposite direction removes the screw 603, unlocking the fixing device 6. Then, pushing the positioning block 507 out of the positioning hole 508 allows the LED light strip 2 to be removed for maintenance. The entire device achieves initial fixation through the positioning device 5, anti-loosening locking through the fixing device 6, and protection through the connector slot and sealing gasket 4.This achieves highly stable installation and long-term reliable operation of the LED light strip 2, thus completing the application process of a highly stable LED light strip.
