[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0019] Please refer to Figure 1-3 As shown, this utility model provides a circuit board with a quick-locking fastener, including a base plate 1 and a circuit board 2. A housing 3 is installed on the upper surface of the base plate 1. Multiple sets of housings 3 are respectively installed on both sides of the base plate 1. A locking component is provided inside the housing 3. A spring-loaded component is provided on one side of the locking component. A first through hole 5 is opened on the upper surface of the housing 3. A second through hole 7 is opened on the upper surface of the housing 3. The second through hole 7 is located on one side of the first through hole 5. Locking posts 16 are installed on both sides of the lower surface of both ends of the circuit board 2. Locking grooves 15 are opened on the lower surface of the locking posts 16. Pressing components are installed on the lower surface of both ends of the circuit board 2.
[0020] Specifically, the lower end of the locking post 16 passes through the second through hole 7 and compresses the spring-loaded component downward, so that one end of the locking component is locked inside the slot 15, thereby fixing the circuit board 2. By pressing down the locking component, one end of the locking component can be pressed upward, thereby causing the other end to disengage from the slot 15. At this time, the spring-loaded component pushes the locking post 16 upward, thereby enabling quick disassembly.
[0021] The engagement assembly includes a claw 6, a mounting pin 10, and a first spring 9. The two ends of the mounting pin 10 are mounted on the inner walls of both sides of the housing 3. The claw 6 is rotatably mounted on the outside of the mounting pin 10. The first spring 9 is mounted on the bottom inside the housing 3. The upper end of the first spring 9 abuts against the bottom of one end of the claw 6. By passing the lower ends of the locking post 16 and the pressing post 14 through the second through hole 7 and the first through hole 5 respectively, the locking post 16 will squeeze the claw 6 to one side and compress the support post 8 downward as it moves downward. The movement of one end of the claw 6 causes the other end to compress the first spring 9 downward. As the locking post 16 moves downward continuously, the rebound force of the first spring 9 pushes one end of the claw 6 upward so that the other end is locked in the slot 15, thus quickly completing the installation of the circuit board 2.
[0022] The rebound assembly includes a support column 8 and a second spring 11. The lower end of the second spring 11 is fixedly installed at the bottom inside the housing 3, and the upper end of the second spring 11 is connected to the lower surface of the support column 8. The second spring 11 uses its own rebound force to push the support column 8 upward, and at the same time pushes the locking column 16 to move upward, thereby pushing the locking column 16 upward.
[0023] The pressing assembly includes a third spring 12, a baffle 13, and a pressing post 14. The upper end of the pressing post 14 extends through the circuit board 2. The third spring 12 is located on the outside of the pressing post 14, with its upper end connected to the lower surface of the circuit board 2 and its lower end connected to the upper surface of the baffle 13. The baffle 13 is installed on the surface of the pressing post 14 and is located at the lower end of the circuit board 2. By pressing down on the upper end of the pressing post 14, the movement of the pressing post 14 causes the baffle 13 to move accordingly and pull down the third spring 12. This allows the lower end of the pressing post 14 to push one end of the claw 6 downward to squeeze the first spring 9, while simultaneously causing the other end of the claw 6 to disengage from the inside of the slot 15. Then, the rebound assembly pushes the claw 16 upward, thereby enabling the circuit board 2 to be quickly disassembled.
[0024] The base plate 1 has mounting holes 4 on its upper surface. Multiple sets of mounting holes 4 are provided to facilitate fixing the base plate 1 with bolts.
[0025] Wherein: the locking post 16 matches the second through hole 7, and the pressing post 14 matches the first through hole 5. Through the second through hole 7 and the first through hole 5, it is convenient for the locking post 16 and the pressing post 14 to pass through the outer shell 3 to assemble and disassemble the circuit board 2.
[0026] Working principle: This utility model is a circuit board with a quick-locking fastener. First, the base plate 1 is fixed by bolts and mounting holes 4. Then, the lower ends of the locking post 16 and the pressing post 14 pass through the second through hole 7 and the first through hole 5, respectively. As the locking post 16 moves downward, it squeezes the locking claw 6 to one side and compresses the support post 8 downward. The movement of one end of the locking claw 6 causes the other end to compress the first spring 9 downward. As the locking post 16 continues to move downward, the rebound force of the first spring 9 pushes one end of the locking claw 6 upward, causing the other end to lock into the slot 15, thus quickly completing the installation of the circuit board 2. When it is necessary to disassemble the circuit board 2, press down on the upper end of the pressing post 14. The movement of the pressing post 14 will cause the baffle 13 to move accordingly and pull down the third spring 12. This will cause the lower end of the pressing post 14 to push one end of the claw 6 downward to squeeze the first spring 9, while the other end of the claw 6 will disengage from the inside of the slot 15. At this time, the compressed second spring 11 will push the support post 8 upward through its own rebound force, and push the claw 16 upward as well. Finally, lift the circuit board 2 upward and pull the claw 16 and the pressing post 14 out of the inside of the outer casing 3, thus completing the disassembly of the circuit board 2.
