[0024] See also Figures 1-4 The utility model provides a technical solution: a printed circuit board stacking structure, comprising a first printed circuit board 1 and a second printed circuit board 2, the second printed circuit board 2 is located above the first printed circuit board 1, the top of the second printed circuit board 2 is provided with two positioning through grooves 6, the insides of the two positioning through grooves 6 are provided with a card slot 12, the top of the first printed circuit board 1 is provided with two sliding grooves 7, the two sliding grooves 7 are provided with a fixing groove 13 on one side away from the center, and a stacking component is arranged on the first printed circuit board 1.

[0025] The stacking assembly includes a stacking plate 3, which is slidably connected in the corresponding sliding groove 7. An adjusting groove 9 is provided on the top of the stacking plate 3, and a shrinking groove 5 is provided at the bottom of the adjusting groove 9. A limiting slide 16 is slidably connected inside the shrinking groove 5. A toggle plate 11 is fixedly connected to the top of the limiting slide 16. The toggle plate 11 is slidably connected in the adjusting groove 9. A mounting block 4 is fixedly connected to one side of the limiting slide 16. The mounting block 4 slides through one side of the shrinking groove 5 and is engaged with the corresponding slot 12.

[0026] A first spring 10 is fixedly connected to the side of the limiting slide 16 away from the mounting block 4, and one end of the first spring 10 away from the limiting slide 16 is fixedly connected to the inner wall of the contraction groove 5. A stabilizing groove 14 is provided on the side of the stacking plate 3 close to the corresponding fixing groove 13, and a mounting plate 8 is slidably connected inside the stabilizing groove 14. Two second springs 15 are fixedly connected to the side of the mounting plate 8 away from the fixing groove 13, and one end of the two second springs 15 away from the mounting plate 8 is fixedly connected to the inner wall of the stabilizing groove 14. There are two stacking assemblies, and the two stacking assemblies are symmetrically arranged on both sides of the first printed circuit board 1.

[0027] Furthermore, when using the device, the operator presses the two mounting plates 8 respectively, and the two mounting plates slide in the corresponding stable grooves 14 and compress the corresponding two second springs 15. Then the operator slides the two stacking plates 3 into the corresponding sliding grooves 7 respectively. When the two stacking plates 3 slide to the limit position, the operator releases the two mounting plates 8. The two mounting plates 8 are reset under the action of the corresponding two second springs 15 and plugged into the corresponding fixing grooves 13, thereby fixing the two stacking plates 3. Then the operator aligns the two positioning through grooves 6 on the second printed circuit board 2 with the two stacking plates 3 on the first printed circuit board 1, and the second printed circuit board 2 is plugged into the two stacking plates 3. When the board 2 is plugged in, the two mounting blocks 4 will be squeezed, and the two mounting blocks 4 will shrink into the corresponding shrinkage grooves 5 under the guidance of their inclined surfaces. The shrinkage of the two mounting blocks 4 will drive the corresponding limiting slides 16 to slide in the corresponding shrinkage grooves 5.

[0028] By engaging the two mounting blocks 4 with the corresponding slots 12, when the second printed circuit board 2 is stacked on the first printed circuit board 1, the second printed circuit board 2 will squeeze the two mounting blocks 4, so that the two mounting blocks 4 can be engaged with the corresponding slots 12 under the support of the corresponding first springs 10, thereby facilitating stable stacking of the second printed circuit board 2, and further improving the stability and reliability of the stacking of the first printed circuit board 1 and the second printed circuit board 2.

[0029] Through the cooperation of the two mounting plates 8 and the two corresponding second springs 15, the two mounting plates 8 can be automatically reset under the support of the corresponding two second springs 15, so that the two mounting plates 8 are engaged with the corresponding fixing grooves 13, so that the two stacking plates 3 can be quickly installed or disassembled, thereby reducing the installation time and cost of the first printed circuit board 1 and the second printed circuit board 2.

[0030] Working principle: the operator presses the two mounting plates 8 respectively, and the two mounting plates slide in the corresponding stable grooves 14 and compress the corresponding two second springs 15. Then the operator slides the two stacking plates 3 into the corresponding sliding grooves 7 respectively. When the two stacking plates 3 slide to the limit position, the operator releases the two mounting plates 8. The two mounting plates 8 will be reset under the action of the corresponding two second springs 15 and plugged into the corresponding fixing grooves 13, thereby fixing the two stacking plates 3. Then the operator aligns the two positioning through grooves 6 on the second printed circuit board 2 with the two stacking plates 3 on the first printed circuit board 1, and the second printed circuit board 2 is plugged in. When the two mounting blocks 4 are connected, the two mounting blocks 4 will be squeezed, and the two mounting blocks 4 will shrink into the corresponding shrinkage grooves 5 under the guidance of their inclined surfaces. The shrinkage of the two mounting blocks 4 will drive the corresponding limiting slides 16 to slide in the corresponding shrinkage grooves 5. The movement of the two limiting slides 16 will drive the corresponding toggle plates 11 to slide in the corresponding adjustment grooves 9. The two limiting slides 16 move and compress the corresponding first springs 10. When the two slots 12 on the second printed circuit board 2 move to the two mounting blocks 4, the two mounting blocks 4 will be engaged with the corresponding slots 12 under the action of the corresponding first springs 10, so as to facilitate the rapid stacking of the second printed circuit board 2 on the first printed circuit board 1.
