Technical Field

[0001] This utility model relates to the technical field of LED light source lamp substrate fixing structure, and in particular to an LED light source lamp substrate fixing structure. Background Technology

[0002] The existing LED light source lamp board fixing structure generally consists of an LED light source lamp board, a lamp holder and a dust cover. During the assembly process, multiple sets of screws are usually required to connect the LED light source lamp board to the lamp holder. This design requires workers to use multiple tools and also requires manual assistance to press the LED light aluminum board into the lamp holder for installation, making the operation cumbersome and inconvenient.

[0003] In addition, since the LED light source substrate, lamp holder and dust cover are all connected by screws, this design greatly increases the difficulty of disassembly for workers when repairing or replacing them. Utility Model Content

[0004] To address the aforementioned shortcomings, the purpose of this utility model is to propose an LED light source substrate fixing structure that requires multiple tools for quick assembly and disassembly and has a simple structure.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] An LED light source substrate fixing structure includes a substrate body, a lamp holder, and a dust cover. The substrate body is provided with a snap-fit ​​groove, and the inner wall of the lamp holder is provided with a reset connector. The substrate body is disposed inside the lamp holder, and the lamp holder is snapped into the snap-fit ​​groove of the substrate body through the reset connector. The top of the lamp holder is provided with a protrusion, and the dust cover is provided with a recess that matches the protrusion. The dust cover is snapped into the protrusion through the recess. The reset connector includes a mounting base, a reset spring, and a positioning pin. The mounting base is disposed on the inner wall of the lamp holder and has a receiving cavity. The reset spring is disposed inside the receiving cavity and is connected to one end of the positioning pin. The other end of the positioning pin can be snapped into the snap-fit ​​groove. The outer wall of the positioning pin is provided with a disassembly protrusion.

[0007] Preferably, in the above-mentioned LED light source substrate fixing structure, the inner wall of the receiving cavity is provided with a guide rail, the outer wall of the positioning pin shaft is provided with a guide slider, and the positioning pin shaft is slidably connected to the guide rail through the guide slider.

[0008] Preferably, in the above-described LED light source substrate fixing structure, the guide rail is arranged along the length direction of the receiving cavity.

[0009] Preferably, in the above-mentioned LED light source substrate fixing structure, the guide slider is adapted to the guide rail.

[0010] Preferably, the above-mentioned LED light source substrate fixing structure further includes a positioning seat, which is disposed inside the receiving cavity, and the positioning seat has a positioning hole, with the end of the reset spring disposed inside the positioning hole.

[0011] Preferably, in the above-mentioned LED light source substrate fixing structure, the periphery of the dust cover is provided with multiple heat dissipation holes.

[0012] Preferably, in the above-mentioned LED light source substrate fixing structure, the top of the dust cover is provided with a connecting seat, and the connecting seat has a hanging hole for easy hanging.

[0013] The beneficial effects of this utility model are:

[0014] (1) When the substrate body and the lamp holder are installed, since the substrate body is provided with a snap-fit ​​groove and the inner wall of the lamp holder is provided with a reset connector, it is only necessary to place the substrate body on the lamp holder and snap it into the snap-fit ​​groove through the reset connector provided by the lamp holder. This design does not require workers to use a variety of tools to complete the assembly, which improves the assembly efficiency and makes the connection structure simpler.

[0015] (2) In addition, the protrusion on the top of the lamp holder is matched with the recess on the dust cover, so that the dust cover can be spliced ​​with the lamp holder. This design can improve the assembly efficiency and facilitate subsequent maintenance and replacement.

[0016] (3) The reset connector includes a mounting base, a reset spring and a positioning pin shaft. Since the mounting base has a receiving cavity, the reset spring is located inside the receiving cavity and is connected to the positioning pin shaft. Therefore, when the substrate body and the lamp holder are installed, under the reaction force of the reset spring, the positioning pin shaft can be abutted against the snap-fit ​​groove provided on the substrate body to achieve the purpose of fixing. When the substrate body needs to be disassembled, since the outer wall of the positioning pin shaft is provided with a disassembly protrusion, the operator only needs to move the disassembly protrusion away from the snap-fit ​​groove with his fingers. The disassembly protrusion can drive the positioning pin shaft to move. Again, by using the reaction force of the reset spring, the positioning pin shaft achieves the purpose of return, so that the positioning pin shaft exits the snap-fit ​​groove. This design makes the entire connection structure simpler and can achieve the purpose of quick disassembly and assembly without the need for multiple tools. Attached Figure Description

[0028] like Figures 1-6 As shown, an LED light source lamp substrate fixing structure includes a substrate body 11, a lamp holder 12, and a dust cover 121. The substrate body 11 is provided with a snap-fit ​​groove 13, and the inner wall of the lamp holder 12 is provided with a reset connector 100. The substrate body 11 is disposed inside the lamp holder 12, and the lamp holder 12 is snapped into the snap-fit ​​groove 13 provided on the substrate body 11 through the reset connector 100. The top of the lamp holder 12 is provided with a protrusion 14, and the dust cover 121 is provided with a recess 15 adapted to the protrusion 14. The dust cover 121 is snapped into the protrusion 14 through the recess 15.

[0029] The reset connector 100 includes a mounting base 16, a reset spring 17, and a positioning pin 18. The mounting base 16 is disposed on the inner wall of the lamp holder 12 and has a receiving cavity 19. The reset spring 17 is disposed inside the receiving cavity 19 and is connected to one end of the positioning pin 18. The other end of the positioning pin 18 can be engaged with the locking groove 13. The outer wall of the positioning pin 18 is provided with a disassembly protrusion 20. When the base plate body 11 is installed with the lamp holder 12, since the base plate body 11 has a locking groove 13 and the inner wall of the lamp holder 12 is provided with the reset connector 100, it is only necessary to place the base plate body on the lamp holder 12 and then engage it with the locking groove 13 through the reset connector 100 provided on the lamp holder 12. This design eliminates the need for workers to use multiple tools to complete the assembly, improving assembly efficiency and simplifying the connection structure.

[0030] It is worth noting that the protrusion 14 on the top of the lamp holder 12 is adapted to the recess 15 on the dust cover 121, so that the dust cover 121 can be spliced ​​with the lamp holder 12. This design can improve assembly efficiency and facilitate subsequent maintenance and replacement.

[0031] In this embodiment, the LED light source substrate fixing structure includes a reset connector 100 comprising a mounting base 16, a reset spring 17, and a positioning pin 18. Since the mounting base 16 has a receiving cavity 19, and the reset spring 17 is located inside the receiving cavity 19, and is connected to the positioning pin 18, when the substrate body 11 and the lamp holder 12 are installed, the positioning pin 18 can abut against the locking groove 13 provided on the substrate body 11 under the reaction force of the reset spring 17, thereby achieving the purpose of fixing. When the substrate body 11 needs to be disassembled, since the outer wall of the positioning pin 18 is provided with a disassembly protrusion 20, the operator only needs to move the disassembly protrusion 20 away from the locking groove 13 with their fingers. The disassembly protrusion 20 can drive the positioning pin 18 to move, and again, using the reaction force of the reset spring 17, the positioning pin 18 achieves its return stroke, causing it to exit the locking groove 13. This design makes the entire connection structure simpler and allows for quick assembly and disassembly without the need for multiple tools.

[0032] In some embodiments of the LED light source substrate fixing structure, the inner wall of the receiving cavity 19 is provided with a guide rail 21, and the outer wall of the positioning pin shaft 18 is provided with a guide slider 22. The positioning pin shaft 18 is slidably connected to the guide rail 21 through the guide slider 22. The guide rail 21 is arranged along the length direction of the receiving cavity 19. The guide slider 22 is adapted to the guide rail 21. This design makes the sliding engagement between the guide slider 22 and the guide rail 21 smoother, and can also limit the positioning pin shaft 18 during extension or return, preventing displacement.

[0033] In some embodiments, the LED light source substrate fixing structure also includes a positioning seat 23, which is located inside the receiving cavity 19. The positioning seat 23 has a positioning hole 24, and the end of the reset spring 17 is located inside the positioning hole 24. This design can limit the reset spring 17 and prevent the reset spring 17 from falling off.

[0034] In this embodiment, the LED light source substrate fixing structure has multiple heat dissipation holes 25 around the periphery of the dust cover 121; this design can improve heat dissipation efficiency.

[0035] In this embodiment, the LED light source substrate fixing structure has a connecting seat 26 on the top of the dust cover 121, and the connecting seat 26 has a hanging hole 27 for easy hanging; this design can improve the practicality of the LED light source substrate fixing structure and achieve the purpose of hanging installation.

[0036] The technical principles of this utility model have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of this utility model and should not be construed as limiting the scope of protection of this utility model in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of this utility model without any inventive effort, and these embodiments will all fall within the scope of protection of this utility model.
