[0016] The following will further describe the present invention in detail with reference to the Figures 1-5 accompanying drawings.

[0017] Please refer to Figures 1-5A modular circuit board connection device for quick disassembly and assembly comprises a support plate 2 and a circuit board body 1 arranged above the support plate 2, four symmetrically distributed mounting blocks 3 are arranged on the side wall of the support plate 2, two symmetrically distributed balancing blocks 10 are arranged on the side wall of the support plate 2, a plurality of symmetrically distributed clamping frames 11 are fixedly installed on the top of the two balancing blocks 10, rubber pads are arranged on the inner sides of the clamping frames 11, a telescopic component is arranged between the two balancing blocks 10 and the support plate 2, the telescopic component comprises a second support plate 8 fixedly installed on the opposite side of the two balancing blocks 10, two symmetrically distributed first support plates 6 are fixedly installed on the side wall of the support plate 2, a connecting plate 7 is arranged between the two first support plates 6 and the second support plates 8 on the same side, an active groove 12 matching the connecting plate 7 on the same side is opened on the opposite side of the two first support plates 6 and the second support plates 8 on the same side, a plurality of symmetrically distributed first springs 13 are fixedly connected between the inner walls on both sides of the connecting plate 7 and the opposite side of the active groove 12 on the same side, and two symmetrically distributed stabilizing rods 9 are arranged between the two balancing blocks 10 and the second support plates 8 on the same side.

[0018] When the device is in use, the staff places the support plate 2 and other structures inside the equipment where the circuit board body 1 is to be installed, and fixes the mounting block 3 to the equipment through the bolts of the prior art. Then, the staff pulls the balancing block 10, thereby stretching the first spring 13 to adjust the distance between the first support plate 6 and the second support plate 8 on the same side, so that the staff can place the circuit board body 1 on the top of the support plate 2. When the circuit board body 1 is placed, the staff releases the balancing block 10, and the balancing block 10 returns to its original position under the elastic force of the first spring 13 on the same side, and makes the clamping frame 11 contact with the side opposite to the balancing block 10, so as to clamp and fix the circuit board body 1, which is beneficial to maintaining the stability of the placement of the circuit board body 1. When the circuit board body 1 needs to be disassembled, it is only necessary to pull the balancing block 10 again to make the clamping frame 11 disengage from the circuit board body 1. Then, the circuit board body 1 can be taken out, which is convenient and quick.

[0019] Two symmetrically distributed limit blocks are fixedly installed at the top and bottom of both ends of the two connecting plates 7. Limit grooves matching the limit blocks on the same side are opened on the inner wall of the top and bottom of the movable groove 12. When the connecting plate 7 slides in the two movable grooves 12 on the same side, the connecting plate 7 slides in the limit groove on the same side with the limit blocks. The cooperation between the limit blocks and the limit grooves helps to prevent the connecting plate 7 from leaving the movable groove 12. There are two symmetrically distributed stabilizing blocks 4 on the side wall of the support plate 2. There is a limiting frame 5 slidably mounted on the top of each of the two stabilizing blocks 4. There is a positioning assembly between each of the two limiting frames 5 and the stabilizing block 4 on the same side. The positioning assembly includes sliders 15 fixedly installed on the inner walls of both sides of the limiting frame 5. There are sliding grooves 14 opened on both sides of the two stabilizing blocks 4, which are matched with the sliders 15 on the same side. A receiving groove 16 is opened at the bottom end of each slider 15. A positioning rod 18 is slidably mounted in each receiving groove 16. A second spring 17 is fixedly connected between the top end of the positioning rod 18 and the inner wall of the top end of the receiving groove 16 on the same side. The bottom inner wall of the sliding groove 14 is provided with a plurality of positioning grooves that are matched with the positioning rods 18 on the same side.

[0020] After the circuit board body 1 is placed, the staff slides the limiting frame 5 sleeved on the top of the stabilizing block 4. There is a slider 15 inside the limiting frame 5, and a sliding groove 14 matched with the slider 15 is opened on the side wall of the stabilizing block 4. Through the cooperation of the slider 15 and the sliding groove 14, it is beneficial to maintain the stability of the sliding of the limiting frame 5. And when the slider 15 slides in the sliding groove 14 on the same side, the positioning rod 18 slides into the receiving groove 16 on the same side under the push of the sliding groove 14, and the positioning rod 18 pushes the second spring 17 on the same side to contract. Subsequently, the positioning rod 18 can be engaged with the positioning groove opened on the bottom inner wall of the sliding groove 14 under the elastic force of the second spring 17 on the same side, which can play a role in positioning the limiting frame 5. The side of the limiting frame 5 that moves into contact with the circuit board body 1 plays a role in limiting and positioning the circuit board body 1, which is beneficial to maintaining the stability of the placement of the circuit board body 1.

[0021] Two symmetrically distributed support blocks are fixedly installed on the side wall of the top end of the positioning rod 18. A support groove matched with the support block on the same side is opened on the inner wall of the receiving groove 16. When the positioning rod 18 slides in the receiving groove 16 on the same side, the positioning rod 18 drives the support block on the same side to slide in the support groove on the same side. Through the cooperation of the support block and the support groove, it is beneficial to maintain the stability of the sliding of the positioning rod 18 and helps to prevent the positioning rod 18 from detaching from the receiving groove 16.

[0022] A groove is opened at the bottom end of the support plate 2. An installation frame 19 is provided in the groove. A fan 20 is provided in the installation frame 19. A plurality of air outlet holes are opened at the top end of the support plate 2 in an annular array distribution. The air outlet holes are all communicated with the groove. Heat dissipation pads are provided on the tops of the support plate 2, the first support plate 6 and the second support plate 8, which not only play a buffering role but also a heat conduction role. The heat dissipation pads can keep a certain distance between the bottom of the circuit board body 1 and the bottoms of the support plate 2, the first support plate 6 and the second support plate 8. Subsequently, the fan 20 can be operated to generate wind force, and the wind force acts on the bottom of the circuit board body 1 through the air outlet holes opened at the top of the support plate 2, which can play a role in heat dissipation.

[0023] The implementation principle of the embodiments of the present invention is as follows: When the device is in use, the staff places structures such as the support plate 2 inside the device where the circuit board body 1 needs to be installed, and fixes the device through bolts of the prior art passing through the mounting block 3. Subsequently, the staff pulls the balance block 10, causing the telescopic component between the balance block 10 and the support plate 2 to stretch, which serves to adjust the distance between the balance block 10 and the support plate 2, facilitating the subsequent placement of the circuit board body 1. After the circuit board body 1 is placed, the staff releases the balance block 10, and the balance block 10 returns to its original position under the pulling of the telescopic component on the same side, and the side of the clamping frame 11 opposite to the balance block 10 comes into contact, serving to clamp and fix the circuit board body 1, which is beneficial to maintaining the stability of the placement of the circuit board body 1. When it is necessary to disassemble the circuit board body 1, just pull the balance block 10 again to make the clamping frame 11 disengage from the circuit board body 1. Subsequently, the circuit board body 1 can be taken out conveniently and quickly. After the circuit board body 1 is placed, the staff slidably sleeved the limiting frame 5 on the top of the stabilizing block 4. The inner side of the limiting frame 5 is provided with a slider 15, and the side wall of the stabilizing block 4 is provided with a chute 14 matching the slider 15. Through the cooperation of the slider 15 and the chute 14, it is beneficial to maintain the stability of the sliding of the limiting frame 5. And when the slider 15 slides in the chute 14 on the same side, a positioning component is provided at the bottom of the slider 15, which can serve to position and stabilize the limiting frame 5. The limiting frame 5 moves to contact the side opposite to the circuit board body 1, serving to limit and position the circuit board body 1, which is beneficial to maintaining the stability of the placement of the circuit board body 1.
