Technical Field
[0001] This utility model relates to the field of linear lights, specifically ultra-thin LED explosion-proof linear lights. Background Technology
[0002] Linear lights are slim, elongated lighting fixtures commonly used for decorative and functional lighting. They utilize LED light sources, featuring low energy consumption, high brightness, and long lifespan. Linear lights can be flexibly installed on ceilings, walls, or under furniture, providing uniform light distribution.

[0023] Example 1
[0024] Please see Figures 1-4 This utility model provides a technical solution: an ultra-thin LED explosion-proof linear light, comprising: a power supply cavity body 2, a positioning hole 13 on the power supply cavity body 2, a slot 11 on the power supply cavity body 2, a locking block 10 disposed in the slot 11, and the locking block 10 connected to a handle 9; an aluminum alloy light source cavity body 1, a heat sink 4, a positioning rod 12 and a fixing block 5 disposed on the aluminum alloy light source cavity body 1, a sliding groove 6 on the fixing block 5, and a thrust spring 7 and a slider 8 disposed in the sliding groove 6;
[0025] In practical use, personnel can pull the power chamber body 2 to move it along the positioning rod 12, so that the positioning rod 12 can be disengaged from the positioning hole 13, and the power chamber body 2 can be disassembled. This facilitates later maintenance and disassembly of the device. The structure is simple and the installation and maintenance are convenient.
[0026] Example 2
[0027] Based on Embodiment 1, a fixing block 5 is provided to facilitate wiring by personnel. The fixing block 5 has a square plate structure and a slot 11 is provided on the fixing block 5. The slot 11 has a "convex" groove structure and a thrust spring 7 is provided in the slot 11. The fixing block 5 limits the side of the power cavity body 2, and the positioning rod 12 is locked in the positioning hole 13. Together with the locking block 10, it is locked in the slot 11, which limits the power cavity body 2 and fixes the power cavity body 2 on the aluminum alloy light source cavity body 1.
[0028] One end of the thrust spring 7 is fixedly connected to the fixed block 5, and the other end is fixedly connected to the slider 8. The slider 8 has an "I"-shaped plate structure. The lower end of the slider 8 is stuck in the slide groove 6 and can slide along the slide groove 6. The operator can pull the handle 9 to make the slider 8 slide along the slide groove 6, thereby compressing the thrust spring 7. The slider 8 is fixedly connected to the handle 9. The handle 9 has a fixedly connected locking block 10. The locking block 10 has a square plate structure. The locking block 10 can be inserted into the locking groove 11 opened on the outer side of the power supply cavity body 2. The locking groove 11 has a square groove structure. When the locking block 10 is disengaged from the locking groove 11, the partial locking of the power supply cavity body 2 is released. The operator can pull the power supply cavity body 2 to move the power supply cavity body 2 along the direction of the positioning rod 12, so that the positioning rod 12 is disengaged from the positioning hole 13, and the power supply cavity body 2 can be disassembled. The operator can then install the power supply, connect the wiring, and maintain the internal components of the device. It is easy for personnel to use and disassemble the device. The structure is simple and the installation and maintenance are convenient.
[0029] Example 3
[0030] Based on Embodiment 2, to improve the device's performance, a square plate structure is provided for the heat sink 4. The heat sink 4 is fixedly connected to the aluminum alloy light source cavity body 1. A light source cavity cover 17 is installed on the aluminum alloy light source cavity body 1 by fixing bolts 18. A light source cavity sealing gasket 16 is fixedly connected to the inner side of the light source cavity cover 17 and contacts the aluminum alloy light source cavity body 1. The heat sink 4 fixedly connected to the aluminum alloy light source cavity body 1 can improve the device's heat dissipation speed, ensuring that the light-emitting component 15 inside the device is at a suitable temperature, thus improving the device's heat dissipation effect. Furthermore, the light source cavity sealing gasket 16 fixedly connected to the inner side of the light source cavity cover 17 can improve the sealing between the light source cavity cover 17 and the aluminum alloy light source cavity body 1, preventing moisture from entering the device through the gap between the light source cavity cover 17 and the aluminum alloy light source cavity body 1 and damaging the light-emitting component 15, thereby improving the device's reliability.
[0031] The fixing block 5 is fixedly connected to the aluminum alloy light source cavity body 1. The light-emitting component 15 is fixedly installed on the aluminum alloy light source cavity body 1. The suspension component 3 is fixedly connected to the aluminum alloy light source cavity body 1. The suspension component 3 on the aluminum alloy light source cavity body 1 can be connected to the suspension rope to install the linear light.
[0032] A positioning rod 12 is fixedly connected to the aluminum alloy light source cavity body 1. The positioning rod 12 has a cylindrical structure and can be inserted into the positioning hole 13 opened on the power supply cavity body 2. A power supply cavity sealing gasket 14 is fixedly connected to the inside of the power supply cavity body 2 and contacts the aluminum alloy light source cavity body 1. An installation component 19 is fixedly connected to the power supply cavity body 2. By setting the power supply cavity sealing gasket 14, moisture can be prevented from entering the device through the gap between the aluminum alloy light source cavity body 1 and the power supply cavity body 2, which would damage the electrical components inside and improve the sealing performance of the device. The above structures work together to improve the adaptability of the device. The installation component 19 can be connected to an external bracket by bolts to install the linear light. The positioning rod 12 can be inserted into the positioning hole 13. The positioning rod 12 can assist personnel in positioning, making it easier for personnel to install the power supply cavity body 2 onto the aluminum alloy light source cavity body 1.
[0033] In actual use, pulling handle 9 disengages the locking block 10 from the slot 11, thus releasing the partial lock on the power supply cavity body 2. The power supply cavity body 2 can then be pulled along the positioning rod 12 to disassemble it, allowing for the installation of the power supply, wiring, and maintenance of the internal components. This facilitates disassembly, provides a simple structure, and is easy to install and maintain. Furthermore, the aluminum alloy light source cavity body 1 and the power supply cavity body 2 form a closed cavity for installing the power supply and wiring, reducing the need for a power supply cavity cover, resulting in a lighter and lower product. The aluminum alloy light source cavity body 1 and the heat sink 4 also provide good heat dissipation, improving the device's cooling performance and ensuring stable operation.
