Description

Technical Field

[0001] The utility model relates to a circuit board, in particular to a circuit board for an LED lamp, belonging to the technical field of circuit boards. Background Technique

[0002] The circuit board is a key component in electronic devices. It can provide a carrier for various electronic components, ensure the electrical connection between them, form a complete circuit, and realize the transmission of current and signals. At the same time, the circuit board can make the circuit more miniaturized and intuitive, which is very important for the mass production of fixed circuits and the optimization of electrical appliance layouts. A circuit board will be installed inside the LED lamp.

[0003] However, most traditional circuit boards are installed inside the LED lamp through multiple bolts. Therefore, when the circuit board is damaged and needs to be disassembled and repaired, it still takes a lot of time to unscrew the bolts, which will waste a certain amount of time and is not convenient for the quick disassembly of the circuit board, thus not facilitating the inspection and maintenance of the circuit board. Content of the Utility Model

[0004] The purpose of the utility model is to provide a circuit board for an LED lamp to solve the above problems. When the circuit board is damaged, it can be quickly disassembled, thus facilitating the inspection and maintenance of the circuit board.

[0005] The utility model realizes the above purpose through the following technical solutions. A circuit board for an LED lamp includes a bottom plate. Two support plates are fixedly connected to the bottom plate. The same circuit board body is placed on the two support plates. A fixing structure is arranged on the bottom plate. The fixing structure includes a push rod and a rotating rod. The rotating rod is rotatably connected to the bottom plate. The push rod is fixedly connected to the rotating rod. Two sliding plates are slidably connected to the bottom plate. The top end of the sliding plate is fixedly connected with a resisting block. The resisting block abuts against the circuit board body. A guiding groove is arranged on the sliding plate. Two guiding shafts are fixedly connected to the end of the rotating rod. The guiding shafts extend into the guiding groove and are slidably connected with the sliding plate. A connecting column is fixedly connected to the bottom plate. A first spring is sleeved outside the connecting column. One end of the first spring abuts against the sliding plate, and the other end of the first spring abuts against the bottom plate.

[0006] Preferably, the end of the sliding plate is in an L-shaped structure, and the sliding plate is perpendicular to the resisting block.

[0007] Preferably, the connecting column penetrates through the sliding plate and is slidably connected with the sliding plate. The cross-section of the end of the bottom plate is in an L-shaped structure.

[0008] Preferably, the push rod is perpendicular to the rotating rod, and one end of the push rod extends to the outside of the bottom plate.

[0009] Preferably, four mounting holes are provided on the bottom plate, and the tops of the two support plates are snap-fitted with the same cover plate.

[0010] Preferably, two openings are provided on both sides of the cover plate, and a clamping structure is provided on the bottom plate.

[0011] Preferably, the clamping structure includes a connecting rod and a clamping block. Two clamping blocks are slidably connected to one side of the bottom plate. One end of the clamping block is snap-fitted with the cover plate, and the other ends of the two clamping blocks are fixedly connected to the same connecting rod.

[0012] Preferably, one end of the cross-section of the clamping block is in a trapezoidal structure, and a second spring is abutted between the connecting rod and the bottom plate.

[0013] The beneficial effects of the present utility model are as follows: When it is necessary to disassemble and repair the circuit board body, by pushing the push rod, the push rod drives the rotating rod to rotate. The rotation of the rotating rod will drive the guide shaft to slide inside the guide groove. During the process of the guide shaft sliding inside the guide groove, the slide plate will drive the abutting block to move away from the circuit board body, and the first spring contracts. As the rotating rod rotates, the orientation of the rotating rod will be the same as the sliding direction of the slide plate. At this time, the distance between the two abutting blocks is the farthest. Then continue to push the push rod to make the rotating rod rotate a certain angle, and then release the push rod. At this time, the first spring will elongate to drive the slide plate to move. The movement of the slide plate will make the guide shaft move towards the end of the guide groove. When the guide shaft moves to the end of the guide groove, one end of it will abut against the slide plate. At this time, the first spring cannot continue to elongate to drive the slide plate to reset. At this time, the two stoppers do not block the circuit board body, and then the circuit board body can be removed from the support plate, thus realizing the rapid disassembly of the circuit board body, facilitating the inspection and maintenance of the circuit board body, and not requiring holding the push rod all the time during the disassembly process, thereby improving the operation convenience. At the same time, since one end of the push rod extends to the outside of the bottom plate, it is more convenient to push the push rod. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation mode

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0020] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown in, a circuit board for an LED lamp includes a bottom plate 1, two support plates 2 are fixedly connected to the bottom plate 1, the same circuit board body 3 is placed on the two support plates 2, a fixing structure 4 is provided on the bottom plate 1, the fixing structure 4 includes a push rod 401 and a rotating rod 402, the rotating rod 402 is rotatably connected to the bottom plate 1, the push rod 401 is fixedly connected to the rotating rod 402, two sliding plates 405 are slidably connected to the bottom plate 1, an abutting block 406 is fixedly connected to the top end of the sliding plate 405, the abutting block 406 abuts against the circuit board body 3, a guiding groove 404 is provided on the sliding plate 405, two guiding shafts 403 are fixedly connected to the end of the rotating rod 402, the guiding shafts 403 extend into the guiding groove 404 and are slidably connected to the sliding plate 405, a connecting column 407 is fixedly connected to the bottom plate 1, a first spring 408 is sleeved outside the connecting column 407, one end of the first spring 408 abuts against the sliding plate 405, and the other end of the first spring 408 abuts against the bottom plate 1.

[0021] As a technical optimization scheme of the present invention, as shown in Figure 1 , Figure 2 and Figure 3 As shown in, the end of the sliding plate 405 is in an L-shaped structure, the sliding plate 405 is perpendicular to the abutting block 406, the connecting column 407 penetrates through the sliding plate 405 and is slidably connected to the sliding plate 405, and the cross section of the end of the bottom plate 1 is in an L-shaped structure. Therefore, the bottom of the circuit board body 3 can be lifted, thus facilitating the heat dissipation of the circuit board body 3.

[0022] As a technical optimization scheme of the present invention, as shown inFigure 1 and Figure 3 As shown, the push rod 401 is perpendicular to the rotating rod 402 , and one end of the push rod 401 extends to the outside of the bottom plate 1 , so that the push rod 401 can be easily pushed.

[0023] As a technical optimization solution of the utility model, Figure 2 and Figure 3 As shown, four mounting holes 8 are provided on the base plate 1, and the top ends of the two support plates 2 are engaged with a same cover plate 6, so the base plate 1 can be mounted and fixed through the mounting holes 8 with bolts.

[0024] As a technical optimization solution of the utility model, Figure 3 and Figure 4 As shown, two openings 7 are provided on both sides of the cover plate 6 , and a locking structure 5 is provided on the bottom plate 1 , so that the wires used to connect the circuit board body 3 can pass through the openings 7 .

[0025] As a technical optimization solution of the utility model, the locking structure 5 includes a connecting rod 502 and a locking block 501. Two locking blocks 501 are slidably connected to one side of the base plate 1. One end of the locking block 501 is engaged with the cover plate 6. The other ends of the two locking blocks 501 are fixedly connected to the same connecting rod 502. One end of the cross-section of the locking block 501 is a trapezoidal structure. A second spring 503 is in contact between the connecting rod 502 and the base plate 1. Therefore, the cover plate 6 can be prevented from detaching from the support plate 2, thereby effectively improving the stability of use.

[0026] When the utility model is in use, first, the bottom plate 1 is installed inside the LED lamp through a plurality of mounting holes 8 in cooperation with bolts. Then, the circuit board body 3 is taken to the two supporting plates 2. The supporting plates 2 can position the circuit board body 3. Then, the two abutting blocks 406 can simultaneously abut against both ends of the circuit board body 3, thereby realizing the installation and fixation of the circuit board body 3. Then, the cover plate 6 is snapped into the top of the supporting plate 2, and the two clamping blocks 501 are engaged with the cover plate 6 to prevent the cover plate 6 from separating from the supporting plate 2. The cover plate 6 can shield and protect the circuit board body 3, thereby reducing the probability of damage to the circuit board body 3. The two openings 7 provided on both sides of the cover plate 6 facilitate the passage of wires for connecting the circuit board body 3. When the circuit board body 3 needs to be disassembled and repaired, by pulling one of the clamping blocks 501, since the two clamping blocks 501 are fixed to the same connecting rod 502, when one of the clamping blocks 501 moves, it will drive the other clamping block 501 to move synchronously, and the second spring 503 contracts. When the two clamping blocks 501 are not engaged with the cover plate 6, the cover plate 6 can be removed from the supporting plate 2. At this time, the cover plate 6 will not shield the circuit board body 3. Then, by pushing the push rod 401, the push rod 401 drives the rotating rod 402 to rotate. The rotation of the rotating rod 402 will drive the guide shaft 403 to slide inside the guide groove 404. During the process of the guide shaft 403 sliding inside the guide groove 404, the sliding plate 405 will drive the abutting block 406 to move away from the circuit board body 3, and the first spring 408 contracts. As the rotating rod 402 rotates, the orientation of the rotating rod 402 will be the same as the sliding direction of the sliding plate 405. At this time, the distance between the two abutting blocks 406 is the farthest. Then, continue to push the push rod 401 to make the rotating rod 402 rotate a certain angle, and then release the push rod 401. At this time, the first spring 408 will extend to drive the sliding plate 405 to move. The movement of the sliding plate 405 will make the guide shaft 403 move towards the end of the guide groove 404. When the guide shaft 403 moves to the end of the guide groove 404, one end of it will abut against the sliding plate 405. At this time, the first spring 408 cannot continue to extend to drive the sliding plate 405 to reset. At this time, the two abutting blocks 406 do not abut against the circuit board body 3. Then, the circuit board body 3 can be removed from the supporting plate 2, thereby realizing the rapid disassembly of the circuit board body 3, facilitating the maintenance and repair of the circuit board body 3, and not requiring continuous holding of the push rod 401 during the disassembly process, thereby improving the operation convenience. At the same time, since one end of the push rod 401 extends outside the bottom plate 1, it is more convenient to push the push rod 401.
