[0002] With the rapid development of electronic technology, printed circuit boards (PCBs) play a vital role in electronic devices. Double-sided PCBs are widely used in various electronic devices because they can be wired on both sides, enabling more circuit connections within a limited space. However, existing double-sided PCBs have problems such as simple structure and instability during use.

[0003] In response to the above problems, regarding the technical problems that the existing double-sided PCB circuit boards do have a simple structure and are unstable during use, after a lot of searches, a double-sided PCB circuit board structure with patent publication number CN219678798U was found, which belongs to the field of circuit board technology. The device contacts the upper and lower plates through the cooperation of the upper outer frame and the lower outer frame. Under the cooperation and fixation of the control bolt and the control groove, the circuit board body is clamped from the edge to make the circuit board body become one. In addition to acting on the lower plate, the gravity of the electronic components will also act on the upper plate through the transmission of the upper and lower outer frames, thereby preventing the lower plate from separating from the upper plate due to excessive gravity and avoiding damage to the equipment structure.

[0004] However, the aforementioned double-sided PCB circuit board still has some problems. For example, the upper and lower outer frames of the device require the use of multiple control pins and control slots during installation, resulting in low overall assembly and disassembly efficiency and poor maneuverability. To address these issues, the present invention proposes a double-sided PCB circuit board. Utility Model Content

[0026] The following is a combination of the appended examples of the present invention Figures 1-8, clearly and completely describe the technical solutions in the embodiments of the present utility model.

[0027] See also Figure 1-8 In the embodiment of the utility model, a double-sided PCB circuit board includes a first plate body 1 and a second plate body 2 on which a circuit board body 3 is installed, a slider 11, which is arranged on the side of the second plate body 2 facing away from the circuit board body 3, and a slide groove 7 for the slider 11 to slide is opened on the first plate body 1, and the slide groove 7 is a structure with an opening at one end and a closed end. The limit plate 10 is movably arranged at the opening of the slide groove 7 and is movably connected to the first plate body 1. A receiving groove 24 for the movement of the limit plate 10 is provided on the first plate body 1, and a spring 26 fixedly connected to the limit plate 10 is provided in the receiving groove 24. The first plate body 1 is provided with an embedding groove 25 for the limit plate 10 to be embedded in the receiving groove 24. The moving block 6 is movably arranged on the first plate body 1, and a moving groove 5 for the movement of the moving block 6 is provided on the first plate body 1. The moving groove 5 and the receiving groove 24 are connected, and the moving block 6 is fixedly connected to the limit plate 10.

[0028] Specifically, when connecting the first plate body 1 and the second plate body 2, the limiting plate 10 is driven by the moving block 6 to slide into the receiving groove 24. At this time, the limiting plate 10 squeezes the spring 26, and then the slider 11 on the second plate body 2 can slide smoothly from the open end of the slide groove 7, and then move to a suitable position in the slide groove 7 to achieve preliminary connection positioning. After that, the moving block 6 is released, so that the limiting plate 10 is reset under the elastic force of the spring 26, so that the end of the limiting plate 10 away from the moving block 6 is embedded in the embedding groove 25, thereby achieving the limitation of the slider 11, that is, completing the installation of the first plate body 1 and the second plate body 2. The overall operation is simple, thereby improving the overall installation efficiency.

[0029] It should be noted that the slider 11 and the slide groove 7 are T-shaped structures that are intended to match, and the moving groove 5 and the receiving groove 24 are connected so that the moving block 6 can connect and interact with the limit plate 10. When it is necessary to release the limit on the slider 11, the limit plate 10 is pulled out of the embedded groove 25 by moving the moving block 6 and returned to the receiving groove 24. At this time, the slider 11 can slide out from the opening of the slide groove 7 to realize the separation of the first plate body 1 and the second plate body 2.

[0030] In the embodiment of the present utility model, Figure 4 、 Figure 5 、 Figure 6 and Figure 7As shown, the first plate body 1 is provided with two cavities 14 relative to the slide groove 7, and through holes 16 communicating with the two cavities 14 are respectively penetrated on both sides of the first plate body 1. A plurality of relatively staggered heat conducting plates 13 are fixedly connected in the cavity 14. Specifically, the cavity 14 can play a certain heat dissipation role, and the through holes 16 can be used for heat dissipation and ventilation, so that the air inside and outside the cavity 14 can circulate. The heat conducting plates 13 can improve the heat conduction efficiency and contribute to the heat dissipation of the circuit board.

[0031] In the embodiment of the present utility model, Figure 6 and Figure 7 As shown, a first rotating shaft 19, a second rotating shaft 21 and a third rotating shaft 23 are rotatably provided in the first plate body 1, and a driving gear 8 is sleeved on the third rotating shaft 23. The slider 11 is fixedly connected to a first rack 12 that meshes with the driving gear 8, and the second rotating shaft 21 is sleeved with a driven gear 22 that meshes with the driving gear 8. The first rotating shaft 19 is sleeved with a sub-gear 18. The first rotating shaft 19 and the second rotating shaft 21 are connected by a belt transmission mechanism 20. There are multiple through holes 16, and a baffle 15 for blocking them is provided at each of the multiple through holes 16. The baffle 15 is movably provided in the first plate body 1, and a connecting plate 17 is fixedly connected to the multiple baffles 15. The end of the connecting plate 17 facing away from the baffle 15 is fixedly connected to the second rack 9, and the second rack 9 meshes with the sub-gear 18. Specifically, when the slider 11 is in the sliding When it moves in the groove 7, it will drive the first rack 12 to move, thereby rotating the driving gear 8. The rotation of the driving gear 8 will drive the driven gear 22 to rotate. Since the first rotating shaft 19 and the second rotating shaft 21 are connected by a belt transmission mechanism 20, the rotation of the driven gear 22 will drive the first rotating shaft 19 to rotate through the belt transmission mechanism 20, and the first rotating shaft 19 drives the sub-gear 18 to rotate, and the sub-gear 18 will drive the second rack 9 to move, thereby controlling the position of the baffle 15 and realizing the opening or closing control of the through hole 16; further, the diameter of the driving gear 8 is larger than the diameter of the driven gear 22. Such a design can realize the change of the rotation speed and increase the rotation speed of the sub-gear 18; it should be noted that the structure and installation of the belt transmission mechanism 20 are prior art and will not be described in detail here.

[0032] In the embodiment of the present utility model, Figure 1 and Figure 7 As shown, a filter screen 4 is fixedly connected to the through hole 16. Specifically, the filter screen 4 can prevent dust and other impurities from entering the interior of the circuit board, thereby protecting the circuit board.

[0033] Working principle: When connecting the first plate body 1 and the second plate body 2, the limiting plate 10 is driven by the moving block 6 to slide into the receiving groove 24. At this time, the limiting plate 10 squeezes the spring 26, and then the slider 11 on the second plate body 2 can slide smoothly from the open end of the slide groove 7, and then move to the appropriate position in the slide groove 7 to achieve preliminary connection positioning. After that, the moving block 6 is released, so that the limiting plate 10 is reset under the elastic force of the spring 26, so that the end of the limiting plate 10 away from the moving block 6 is embedded in the embedding groove 25, thereby achieving the limitation of the slider 11, that is, completing the installation of the first plate body 1 and the second plate body 2. The overall operation is simple, thereby improving the overall installation efficiency.
