Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Reference Figure 1-Figure 3 , the utility model provides an embodiment: a PCBA with a detachable shielding cover, comprising a mounting plate 1, a shielding cover 2 is arranged on the upper surface of the mounting plate 1, a positioning plate 3 is fixedly connected to the outer wall of the shielding cover 2, the outer wall of the positioning plate 3 is slidably connected to the inside of the mounting plate 1, a clamping block 10 is fixedly connected to the outer wall of the positioning plate 3, a sliding rod 5 is slidably connected to the inside of the mounting plate 1, one end of the sliding rod 5 is fixedly connected to a pull plate 6, the outer wall of the pull plate 6 is slidably connected to the inside of the mounting plate 1, the other end of the sliding rod 5 is fixedly connected to a hook 9, the outer wall of the sliding rod 5 is fixedly connected to a push plate 7, a first spring 8 is arranged inside the mounting plate 1, both ends of the first spring 8 are fixedly connected to the outer wall of the push plate 7, and a mounting assembly is arranged inside the mounting plate 1; the mounting assembly comprises a mounting hole 4, and the mounting hole 4 is opened inside the mounting plate 1;

[0025] Specifically, when the shielding cover 2 needs to be quickly disassembled, it is only necessary to slide the pull plate 6 inward, which can drive the slide bar 5 to push the push plate 7. In this process, the push plate 7 will compress the first spring 8. At the same time, the slide bar 5 will also drive the hook 9 to slide inside the mounting plate 1 until the hook 9 no longer restricts the block 10. At this time, the shielding cover 2 can be pulled upward. In this way, the positioning plate 3 can slide out from the inside of the mounting plate 1 to achieve rapid disassembly of the shielding cover 2. This not only improves the convenience of the circuit board 11, but also makes the inspection and maintenance of the circuit board 11 and the replacement of the shielding cover 2 simpler and faster.

[0026] Reference Figure 1 , Figure 2 and Figure 4 The interior of the mounting plate 1 is fixedly connected with a slide rail 12, and the outer wall of the slide rail 12 is rotatably connected with a turntable 13; the outer wall of the turntable 13 is rotatably connected to the interior of the mounting plate 1, and the interior of the turntable 13 is slidably connected with four rotating rods 16, the outer walls of two rotating rods 16 are fixed with a second connecting plate 20, and the outer walls of the other two rotating rods 16 are fixedly connected with a first connecting plate 17; the outer walls of the first connecting plate 17 and the second connecting plate 20 are both rotatably connected with a slide seat 18, and the interior of the slide seat 18 is slidably connected to the outer wall of the slide rail 12; the interior of the slide seat 18 is slidably connected with a limit rod 15, and the outer wall of the limit rod 15 is sleeved with a second spring 14; both ends of the second spring 14 are fixedly connected to the outer wall of the slide seat 18; a circuit board 11 is provided on the upper surface of the mounting plate 1, and a clamping plate 19 is fixedly connected to the outer wall of the clamping plate 19, and the outer wall of the clamping plate 19 is slidably connected to the interior of the mounting plate 1, and the outer wall of the clamping plate 19 is slidably connected to the outer wall of the circuit board 11;

[0027] Specifically, when the circuit board 11 needs to be fixed in position, the slides 18 on both sides are pulled by the elastic force of the second spring 14. This not only ensures the stable movement of the slide 18, but also limits the position of the slide 18 and the second spring 14 through the limit rod 15. The slide 18 slides on the outer wall of the slide rail 12, and the sliding of the slide 18 pushes the turntable 13 to rotate through the second connecting plate 20. This enables the first connecting plate 17 to drive the slides 18 on the other two sides to slide. This ensures that the clamping plate 19 can accurately clamp the circuit board 11, thereby achieving the position fixation of the circuit board 11. This not only improves the stability of the circuit board 11, but also effectively guarantees its normal operation.

[0028] Working principle: When the shielding cover 2 needs to be quickly disassembled, the pull plate 6 is slid inward to drive the slide bar 5 to push the push plate 7, so that the push plate 7 can compress the first spring 8, and the slide bar 5 will also drive the hook 9 to slide inside the mounting plate 1 until the hook 9 no longer restricts the block 10, and then the shielding cover 2 is pulled upward, so that the positioning plate 3 can slide out from the inside of the mounting plate 1, thereby achieving the effect of quickly disassembling the shielding cover 2, improving the convenience of the circuit board 11, facilitating the inspection and maintenance of the circuit board 11 and the replacement of the shielding cover 2, and when the circuit board 11 needs to be fixed in position When the turntable 13 is rotated, the first connecting plate 17 drives the slides 18 on the other two sides to slide, until the clamping plate 19 completely clamps the circuit board 11, thereby achieving the effect of fixing the position of the circuit board 11, improving the stability of the circuit board 11, and ensuring the normal operation of the circuit board 11.
