DETAILED DESCRIPTION

[0026] The following will clearly and completely describe the technical solutions of the present invention through detailed embodiments and in conjunction with the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] Please refer to Figures 1 to 6This embodiment provides a locking structure for a heat sink bracket and a lamp tube, comprising a heat sink bracket 1 and a lamp tube 2. The lamp tube 2 is a light-transmitting hollow housing structure. A mounting groove 21 is provided on the side of the lamp tube 2 adjacent to the heat sink bracket 1, communicating with the inner cavity of the lamp tube 2. The heat sink bracket 1 is rotatably connected to at least one rotating locking block 3 for extending into the inner cavity of the lamp tube 2. The width of the rotating locking block 3 is less than or equal to the width of the mounting groove 21. Each end of the rotating locking block 3 along its length is provided with a pressing portion 31 for abutting against the inner sidewall of the lamp tube 2. In this manner, the rotating locking block cooperates with the mounting groove on the lamp tube to quickly lock and release the lamp tube from the heat sink bracket, improving assembly efficiency and facilitating disassembly and maintenance. Specifically, when the rotating locking block is rotated parallel to the mounting groove, the lamp tube can be removed from the heat sink bracket. When the rotating locking block is rotated perpendicular to the mounting groove, the pressing portion on the rotating locking block and the heat sink bracket can cooperate to clamp the lamp tube, thereby securely locking the lamp tube to the heat sink bracket.

[0028] In some embodiments, reference Figures 1 to 5 The rotating lock block 3 is rotatably connected to the heat sink bracket 1 via a rotating assembly 4. Specifically, the rotating assembly 4 includes a rotating head 41 and a screw 42. The heat sink bracket 1 is provided with an axial hole 11 that is rotatably connected to the rotating head 41. The rotating lock block 3 is fixedly connected to the bottom of the rotating head 41 via the screw 42. In this way, simply driving the rotating lock block to rotate will drive the rotating assembly to rotate synchronously, thereby locking and unlocking the lamp tube.

[0029] In some specific embodiments, reference Figure 1 and Figure 3 The end of the rotating head 41 away from the rotating locking block 3 is provided with a slot 411 for easy twisting and rotation. In this way, a tool such as a flat-blade screwdriver can be inserted into the slot to facilitate applying external force to twist the rotating head.

[0030] As an improved implementation, refer to Figure 1 、 Figure 4 and Figure 5The outer circumference of the rotating head 41 is sheathed with a spring 43. A first annular rib 412 is provided at the end of the rotating head 41 away from the rotating lock block 3. A second annular rib 12 is provided at the end of the axial hole 11 close to the rotating lock block 3. The two ends of the spring 43 respectively abut against the first annular rib 412 and the second annular rib 12. By providing the spring, the rotating head can be pressed to push the rotating lock block toward the inner cavity of the lamp tube a short distance, and then the rotating head can be twisted to drive the rotating lock block to rotate. In this way, during the process of rotating the rotating lock block, the pressing portion on the rotating lock block is separated from the inner wall of the lamp tube, which can avoid significant wear caused by direct contact between the rotating lock block and the inner wall of the lamp tube and is more conducive to rotating the rotating lock block to lock or unlock the lamp tube.

[0031] In some embodiments, reference Figure 1 、 Figure 2 、 Figure 4 and Figure 5 An LED light board 5 having an LED light 51 is provided on one side of the heat dissipation bracket 1 near the lamp tube 2. The LED light board 5 is penetrated by a limiting hole 52 for limiting the rotation of the rotary lock block 3. A limiting boss 32 is provided on one side of the rotary center axis of the rotary lock block 3, protruding toward the limiting hole 52. The limiting boss 32 is adapted to the shape of the limiting hole 52. In this way, the limiting hole provided on the LED light board can be used to cooperate with the limiting boss on the rotary lock block to limit the free rotation of the rotary lock block, thereby preventing the lamp tube from being easily separated from the heat dissipation bracket due to accidental contact by external force, thereby playing a better role in preventing it from falling off. When the rotary head is pressed to push the rotary lock block toward the inner cavity of the lamp tube for a short distance, the limiting boss has been removed from the limiting hole at this time, so the rotary head can be turned normally to drive the rotary lock block to rotate.

[0032] In some specific embodiments, reference Figure 1 、 Figure 4 and Figure 5 , the side walls of the limiting boss 32 and the inner walls of the limiting hole 52 are both provided with limiting surfaces 33. As an example, the limiting surface on the limiting boss is perpendicular to the width direction of the rotating lock block, and the limiting surface in the limiting hole is perpendicular to the length direction of the LED light board, so that the rotating lock block is in a locked state when it is perpendicular to the assembly slot, and in an unlocked state when it is parallel to the assembly slot. Of course, in some other embodiments, they can also be swapped according to design requirements, that is, the limiting surface on the limiting boss is parallel to the width direction of the rotating lock block, and the limiting surface in the limiting hole is parallel to the length direction of the LED light board, so that the rotating lock block is in a locked state when it is perpendicular to the assembly slot, and in an unlocked state when it is parallel to the assembly slot.

[0033] As an example, the limiting boss 32 is a cylinder with a side wall having a vertical plane.

[0034] In some specific embodiments, as an example, refer to Figures 1 to 6 The lamp tube 2 is cylindrical in shape as a whole, the mounting groove 21 extends along the length of the lamp tube 2, and the LED light board 5 is distributed along the length of the mounting groove 21. Of course, those skilled in the art will appreciate that the shape of the lamp tube 2 is not limited to a cylindrical shape. In other embodiments, the shape of the lamp tube 2 can be appropriately adjusted according to design requirements (such as lighting needs), such as a disc, a rectangular parallelepiped, or a special-shaped box, so that the lamp tube 2 can have different lighting effects.

[0035] In some specific embodiments, reference Figures 1 to 6 One end of the heat dissipation bracket 1 is provided with a magnetic POGOPIN connector 6, and the other end of the heat dissipation bracket 1 is provided with a magnet block 7, and the magnetic POGOPIN connector 6 is electrically connected to the LED light board 5.

[0036] Specifically, such as Figure 1 As shown, the upper portion of one end of the heat dissipation bracket 1 has a groove 13 for embedding the magnet block 7, and the upper portion of the other end of the heat dissipation bracket 1 is fixed with a support column 8 by screws, and the magnetic POGOPIN connector 6 is embedded and connected to the upper portion of the support column 8 through an isolation sleeve 9. Figure 6 As shown, one end of the lamp holder 200 is provided with an embedding groove 201 embedded with the heat dissipation bracket 1, and one end of the embedding groove 201 is provided with a magnetic member 202 magnetically attracted to the magnet block 7, and the other end of the embedding groove 201 is provided with a magnetic mother seat 203 electrically connected to the magnetic POGOPIN connector 6, and the magnetic mother seat 203 is electrically connected to the power supply module 204 inside the lamp holder 200. As an example, the magnetic member 202 is an iron block or a magnet block. The power supply module 204 is a power driver. In this way, the heat dissipation bracket 1, the lamp tube 2, and the LED light board 5 form a lamp head 100 that can be separated from the lamp holder 200 after assembly. Since the lamp head 100 adopts a magnetic attraction method, it can be easily and quickly assembled and disassembled, and an effective electrical connection is formed with the magnetic POGOPIN connector 6 and the magnetic mother seat 203.

[0037] In some specific embodiments, the rotation center axis of the rotating lock block 3 is perpendicular to the center axis of the lamp tube 2. In this way, the structural layout is more reasonable and easy to assemble.

[0038] In some specific embodiments, as an example, refer to Figures 1 to 3 and Figure 6, the number of the rotating lock blocks 3 is provided with two, and is symmetrically distributed at both ends of the heat dissipation bracket 1. In this way, the lamp tube and the heat dissipation bracket have a relatively balanced locking force after being locked and connected, so that the lamp tube can be more firmly assembled on the heat dissipation bracket. Of course, those skilled in the art will know that the number of rotating lock blocks 3 is not limited to two. In some other embodiments, the number of rotating lock blocks 3 can be appropriately adjusted according to design requirements (such as according to the length, weight, shape, etc. of the lamp tube), such as providing one, three, four, five, six or more rotating lock blocks, so that the lamp tube can be more stably locked and fixed on the heat dissipation bracket.

[0039] When assembling the lamp holder, refer to Figure 4 and Figure 5 When the rotating head 41 is pressed downward to push the rotating lock block 3 toward the inner cavity of the lamp tube 2 for a short distance, the limiting boss 32 has been moved out of the limiting hole 52 at this time, and the spring 43 is in a compressed state. The rotating head 41 is turned to drive the rotating lock block 3 to rotate 90° until it is parallel to the assembly groove 21. At this time, the rotating lock block 3 falls on the surface of the LED light board 5, corresponding to the unlocked state. The rotating lock block 3 can pass through the assembly groove 21 on the lamp tube 2, so that the lamp tube 2 can be embedded toward the heat dissipation bracket 1 or the lamp tube 2 can be removed from the heat dissipation bracket 1. After the lamp tube 2 is installed toward the heat dissipation bracket 1, continue to turn the rotating head 41 and drive the rotating lock block 3 to rotate 90° until it is perpendicular to the assembly groove 21. At this time, the spring 43 releases the elastic force and pushes the rotating head 41 to move up and reset. The limiting boss 32 on the rotating lock block 3 slides back into the limiting hole 52 on the LED light board 5. The pressing parts 31 at both ends of the rotating lock block 3 press the inner wall of the lamp tube 2, corresponding to the locking state.

[0040] After assembling the lamp holder 100, refer to Figure 6 , insert the lamp holder 100 into the embedding slot 201 of the lamp holder 200. On the one hand, the magnetic POGOPIN connector 6 on the lamp holder 100 is attracted and electrically connected to the magnetic mother seat 203 on the lamp holder 200. On the other hand, the magnet block 7 on the lamp holder 100 is magnetically attracted and connected to the magnetic part 202 on the lamp holder 200, ensuring that the lamp holder 100 is firmly fixed to the lamp holder 200 by magnetic attraction.

[0041] The above embodiments are merely illustrative of the concepts and technical solutions of this utility model and are not intended to limit this utility model. Anyone skilled in the art may modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by persons skilled in the art without departing from the spirit and technical concepts disclosed in this utility model shall be covered by the claims of this utility model.

[0042] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
