Abstract
Description
Technical Field
[0001] This utility model relates to the field of LED lighting technology, specifically a low-voltage LED light strip. Background Technology
[0002] Low-voltage LED light strips generally refer to LED light strips with an operating voltage lower than the human body's safe voltage of 36V. They are driven by converting 220V AC mains power into DC power lower than 36V through an external power supply. Existing low-voltage LED light strips include a circuit board, on which LED beads are soldered, and the circuit board is wrapped with an outer sheath.
[0003] According to a search, Chinese patent document CN215061454U discloses a low-voltage LED light strip with a built-in tensile sleeve. The design involves a sleeve between the circuit board and the outer sheath, with the sleeve separated from the circuit board but bonded to the outer sheath. When the light strip is under stress, the tensile force is mainly applied to the outer sheath and the sleeve, while the circuit board experiences less stress and is less prone to breakage. However, during use, the bonded sleeve to the outer sheath makes it prone to separation under repeated pulling, leading to reduced tensile strength and a shorter lifespan. Furthermore, because the light strip is located inside the sleeve, it is easily moved during sleeve extension, potentially damaging the light strip or causing the light emission position to shift, thus reducing the diffused light effect.

[0008] Preferably, the outer side of the protective jacket has a through hole, the top side of the protective jacket has a through groove, the inner side of the through groove is fitted with a transparent soft shell, the inner side of the protective jacket has a connecting groove, and a total of four reinforcing steel bars are provided.
[0009] The above technical solution facilitates light transmission through the transparent soft shell, and the through groove allows for easy installation and locking of the transparent soft shell.

[0010] Preferably, a connecting post is fixedly installed on the outer side of the tensile inner sleeve, and a second through hole is opened on the top side of the connecting post. The second through hole and the connecting threaded sleeve are arranged in groups of two, with a total of four groups.

[0015] Through the above technical solution, the circuit board can be easily locked and limited by the two sets of fixed seats. This makes installation convenient and improves the limiting effect.

[0016] Preferably, the movable rod is movably installed inside the limiting hole, and the movable rods are arranged in groups of two, with a total of two groups. A fastening spring is fixedly installed between the top end of the movable rod and the fixed seat.
[0017] With the above technical solution, during use, after the circuit board is engaged inside the two sets of fixed seats, the moving rod and pressure plate are reset under the action of the fastening spring, and the circuit board is squeezed and reinforced. Thus, when it is pulled, the fastening spring generates a reaction force and continuously limits the circuit board, thereby avoiding the circuit board from tangling and changing the light path, which would require subsequent adjustments.

[0019] 1.

[0028] Example 1:
[0029] like Figure 1-5 As shown, the present invention provides a low-voltage LED light strip, including a protective jacket 1, a reinforcing steel bar 2 fixedly installed on the inner side of the protective jacket 1, a tensile inner sleeve 3 installed on the inner side of the protective jacket 1 by snap-fit, a connecting screw sleeve 4 provided inside the tensile inner sleeve 3, a fixing seat 5 fixedly installed on the bottom side of the inner side of the tensile inner sleeve 3, a circuit board 6 installed on the inner side of the fixing seat 5 by snap-fit, an LED bead 7 provided on the top side of the circuit board 6, a moving rod 8 provided on the top side of the fixing seat 5, a pressure plate 9 fixedly installed at the bottom end of the moving rod 8, and a transparent soft shell 10 installed on the top side of the protective jacket 1 by snap-fit.
[0030] Specifically, the outer side of the protective jacket 1 has an insertion hole 101, and the top side of the protective jacket 1 has a through groove 102. A transparent soft shell 10 is installed inside the through groove 102 by snap-fit. A connecting groove 103 is provided inside the protective jacket 1, and a total of four reinforcing steel bars 2 are provided. The advantages are that the transparent soft shell 10 allows light to pass through, the through groove 102 facilitates the installation of the transparent soft shell 10 and its snap-fit and limiting position, and the connecting groove 103 facilitates the positioning and installation of the tensile inner sleeve 3 and provides a reinforcing and limiting effect.
[0031] Specifically, a connecting post 301 is fixedly installed on the outer side of the tensile inner sleeve 3. A second through hole 302 is provided on the top side of the connecting post 301. Two through holes 302 and four connecting threaded sleeves 4 are arranged in a group, with the connecting threaded sleeve 4 located on the bottom side of the inner side of the second through hole 302. The advantage is that the second through hole 302 facilitates the insertion of bolts and fixation to the connecting threaded sleeve 4, thereby improving the connection stability between the tensile inner sleeve 3 and the protective outer sleeve 1 and preventing detachment. Simultaneously, the connecting post 301 facilitates engagement with the connecting groove 103, improving the fit.
[0032] Specifically, the tensile inner sleeve 3 has through holes 303 on its front side, with two sets of two through holes 303 in total. The top side of the tensile inner sleeve 3 has an installation groove 304, the size and shape of which matches the transparent soft shell 10. The advantages are that the through holes 303 facilitate insertion and engagement with the reinforcing steel bars 2, thereby improving stability and tensile strength. Furthermore, the installation groove 304 facilitates the limiting and engaging of the transparent soft shell 10 during installation, preventing it from falling off during use.
[0033] Example 2:
[0034] like Figure 1-5 As shown, this is an improvement on the previous embodiment. Specifically, the fixing base 5 has an L-shaped structure, and two fixing bases 5 are provided. They are respectively fixedly installed on the bottom side of the inner side of the tensile inner sleeve 3. Limiting holes 501 are provided on the top side of the fixing base 5. The limiting holes 501 are arranged in groups of two, and there are two groups in total. The advantage is that the two groups of fixing bases 5 facilitate the engagement and limiting of the circuit board 6, which not only facilitates installation but also improves the limiting effect. At the same time, the limiting holes 501 facilitate the movement of the moving rod 8, thereby facilitating the movement of the pressure plate 9 to reinforce the circuit board 6.
[0035] Specifically, the movable rod 8 is movably installed inside the limiting hole 501, and two sets of movable rods 8 are provided in pairs. A fastening spring 801 is fixedly installed between the top of the movable rod 8 and the fixed seat 5. The advantage is that after the circuit board 6 is engaged inside the two sets of fixed seats 5, the movable rod 8 and the pressure plate 9 are reset under the action of the fastening spring 801, and the circuit board 6 is squeezed and reinforced. Therefore, when it is pulled, the fastening spring 801 generates a reaction force and continuously limits the circuit board 6, thereby avoiding the circuit board 6 from entanglement and changes in the light path, which would require subsequent adjustments.
[0036] In use, bolts are used to connect and fix the protective outer sleeve 1 and the tensile inner sleeve 3 by passing through the first through hole 101 and the second through hole 302. This helps to improve the connection stability between the protective outer sleeve 1 and the tensile inner sleeve 3, making it less likely to fall off. Furthermore, the six sets of connecting posts 301 are engaged with the connecting groove 103, and the four reinforcing steel bars 2 help to distribute the force points during pulling and reinforce the connection between the protective outer sleeve 1 and the tensile inner sleeve 3, improving the tensile strength and service life. At the same time, during use, after the circuit board 6 is engaged inside the two sets of fixing seats 5, the moving rod 8 and the pressure plate 9 are reset under the action of the fastening spring 801, which squeezes and reinforces the circuit board 6. Thus, when it is pulled, the fastening spring 801 generates a reaction force and continuously limits the circuit board 6, thereby preventing the circuit board 6 from tangling or changing the light path and requiring subsequent adjustments.
