[0002] LED lamps often use aluminum alloy as the metal heat sink material. This is because aluminum alloy has good thermal conductivity and is lightweight, making it ideal for heat dissipation design in LED lamps. Aluminum alloy can effectively transfer the heat generated by the LED lamp to the external environment, ensuring that the operating temperature of the LED is within a safe range.

However, when the lamp needs to be replaced, it is inconvenient to disassemble the radiator and replacement is difficult. Therefore, a metal radiator for LED lamps is proposed to solve the above problem. Utility Model Content

[0030] Reference Figure 1 、 Figure 2 、 Figure 3The utility model provides an embodiment: a metal heat sink for an LED lamp, comprising a heat sink body 1, an upper mounting ring 2 fixedly connected to the outer bottom side of the heat sink body 1, a lower mounting ring 3 fittedly connected to the bottom of the upper mounting ring 2, a lampshade 13 fixedly connected to the interior of the lower mounting ring 3, four fixing tubes 4 fixedly connected to the bottom of the lower mounting ring 3, four mounting holes 12 are opened in the interior of the upper mounting ring 2 and the lower mounting ring 3, a rotating head 5 is rotatably connected to the interior of the mounting hole 12, and the bottom of the rotating head 5 is fixedly connected to Connecting rod 6, the bottom of the connecting rod 6 is fixedly connected to a connecting block 10, the bottom of the connecting block 10 is fixedly connected to a threaded head 11, the threaded head 11 is threadedly connected to the inside of the fixed cylinder 4, the outside of the connecting rod 6 is sleeved with a torsion spring 9, one end of the torsion spring 9 is fixedly connected to the upper part of the connecting block 10, and the other end of the torsion spring 9 is fixedly connected to a limiting circular plate 7, which is rotatably connected to the outside of the connecting rod 6, and the bottom of the radiator body 1 is fixedly connected to a positioning assembly, which is used to connect and install the radiator body 1 and the lampshade 13;

[0031] The positioning assembly includes an insertion rod 15 and a socket 16. The insertion rod 15 is fixedly connected to the four corners of the bottom of the radiator body 1, and the socket 16 is opened at the four upper corners of the inner side of the lampshade 13. The insertion rod 15 is slidably connected to the inside of the socket 16; a limiting groove 8 is opened on the upper part of the mounting hole 12, the limiting circular plate 7 is slidably connected to the inside of the limiting groove 8, and the threaded head 11 is rotatably connected to the inside of the mounting hole 12.

[0032] The rotating head 5 is rotated by the disassembly tool, so that the connecting rod 6 rotates through the rotating head 5 and drives the connecting block 10 to rotate, and at the same time, the threaded head 11 is driven to rotate, so that the threaded head 11 is screwed out or screwed into the interior of the fixed cylinder 4, so that the limiting circular plate 7 is rotated inside the limiting groove 8 so that it no longer presses against the bottom of the limiting groove 8 or presses the limiting circular plate 7 through the limiting groove 8, and the torsion spring 9 is pulled to tighten the threaded head 11 to the fixed cylinder 4, or the threaded head 11 can be removed from the interior of the mounting hole 12, and the connecting head 14 is pulled to make the radiator body 1, so that the insertion rod 15 is pulled out of the interior of the socket 16, so that the connecting head 14 is disassembled and separated from the lampshade 13, which makes it easy and convenient to disassemble the lampshade 13 and the radiator body 1, reducing the maintenance or replacement time.

[0033] Reference Figure 1 、 Figure 2 、 Figure 4The upper part of the radiator body 1 is fitted with a connector 14, and the four corners of the bottom of the connector 14 are fixedly connected with plug blocks 17. Slots 18 are provided at the four corners of the upper side of the inner part of the radiator body 1. The plug blocks 17 are slidably connected to the inside of the slots 18. A card slot 23 is provided on the left side of the inner part of the plug block 17. A slide rod 19 is fixedly connected to the inside of the slot 18. A trapezoidal block 21 is slidably connected to the outside of the slide rod 19. A card block 22 is fixedly connected to the right side of the trapezoidal block 21. The card block 22 is slidably connected to the inside of the card slot 23. A spring 20 is sleeved on the right side of the outer part of the slide rod 19.

[0034] One end of the spring 20 is fixedly connected to the right side wall of the slot 18, and the other end of the spring 20 is fixedly connected to the right side of the trapezoidal block 21. The trapezoidal block 21 is slidably connected to the inside of the slot 18, and the left side of the insert block 17 is fitted and connected to the right inclined surface of the trapezoidal block 21.

[0035] When the shank 17 is fully inserted into the slot 18, the trapezoidal block 21 is no longer squeezed and is pulled by the spring 20 to slide on the outside of the slide bar 19 to fit the shank 17 and drive the block 22 to be inserted into the slot 23, thereby fixing the shank 14 to the radiator body 1. When the radiator body 1 needs to be removed, the luminaire can be held by the shank 14 to avoid burns from residual heat. Because the block 22 and the slot 23 are both trapezoidal and the inclined surface of the block 22 is not fully inserted into the slot 23, the shank 17 can be removed when the radiator body 1 needs to be removed.

[0036] Working principle: When the device needs to be used, the rotating head 5 is rotated by the disassembly tool, so that the connecting rod 6 rotates and drives the connecting block 10 and the threaded head 11 to rotate, so that the threaded head 11 is screwed out of the interior of the fixing cylinder 4, and the limiting circular plate 7 is rotated inside the limiting groove 8 so that it no longer abuts the bottom of the limiting groove 8. The threaded head 11 is removed from the interior of the mounting hole 12, and the connecting head 14 is pulled to drive the radiator body 1 to move the insertion rod 15 and separate it from the lampshade 13, thereby realizing simple and convenient disassembly of the lampshade 13 and the radiator body 1, reducing the time for maintenance or replacement;

[0037] By fitting the connector 14 to the radiator body 1, the insert block 17 is inserted into the interior of the slot 18, and the trapezoidal block 21 is squeezed and pushed, so that the trapezoidal block 21 pulls the spring 20 and slides on the outside of the slide rod 19. When the insert block 17 is fully inserted into the slot 18, the trapezoidal block 21 is pulled by the rebound force of the spring 20, so that it fits with the insert block 17 and the card block 22 is inserted into the interior of the card slot 23, thereby achieving the installation and fixation of the connector 14 to the radiator body 1. When the radiator body 1 needs to be disassembled, the lamp can be held by the connector 14 to avoid burns from residual heat.

[0038] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
