[0002] The PCB board, also known as the printed circuit board, is a basic component used to support and connect electronic components. It is usually composed of insulating materials, covered with conductive paths (circuits) and connection points for connecting electronic components such as chips, resistors, capacitors, etc., to form the basic structure of electronic devices. The PCB board is made through processes such as printing, etching, and electroplating, and can be a single-layer, double-layer or multi-layer structure, which is one of the common and key components in electronic products.

[0003] The PCB board is usually a single substrate, which is fixed inside the product during use to integrate multiple electrical components together. However, when more PCB boards are used in the product, fixing multiple PCB boards separately will increase the system complexity, resulting in a decrease in the internal space utilization rate and an increase in the difficulty of design and manufacturing. To solve the above problems, the technical personnel in this field have proposed a PCB board with an explosion-proof structure to solve the above problems. Content of the Utility Model

[0004] To make up for the above deficiencies, the utility model provides a PCB board with an explosion-proof structure, aiming to improve the problem that the PCB board in the prior art will occupy more space in a relatively complex system, resulting in a decrease in the internal space utilization rate and an increase in the difficulty of design and manufacturing.

[0005] To achieve the above object, the utility model provides the following technical solution: A PCB board with an explosion-proof structure, including a PCB board body. Two placement grooves are opened inside the left side of the PCB board body. A limiting groove is opened on one side inside the placement groove. A return spring is fixedly connected inside the limiting groove. One end of the return spring is fixedly connected with a slider. One side of the slider is fixedly connected with a push rod.

Protective components are arranged at the four corners of the upper and lower sides of the PCB board body, and the protective components are used for protecting the PCB board body.

[0006] Further, the protective component includes a sleeve rod. The sleeve rod is fixedly connected to a corner of the PCB board body. An active rod is slidably connected inside the sleeve rod. A limiting ring is fixedly connected to the outside of the bottom end of the active rod. Communication grooves are opened inside both the sleeve rod and the active rod. A buffer spring is fixedly connected to the inner bottom of the sleeve rod. A protective plate is fixedly connected to the top end of the active rod.

[0007] Furthermore, the slider is slidably connected inside the limiting groove, and the outer part of the return spring is slidably connected to the inner wall of the limiting groove.

[0008] Furthermore, two installation grooves are formed on the left side of the PCB board body, and the outer part of the installation block is slidably connected to the inside of the installation groove.

[0009] Furthermore, one end of the push rod extends to the outside of the PCB board body, and the outer part of the push rod is slidably connected to the inside of the PCB board body.

[0010] Furthermore, the middle part of the double-headed telescopic rod is rotatably connected inside the placement groove, and the outer part of the clamping block is engaged with the inside of the clamping groove.

[0015] 2. In the utility model, by providing a buffer pad on the surface of the protection plate, the impact force can be reduced, and the protection plate can receive the impact force generated during collision, thereby pushing the movable rod towards the inside of the sleeve rod.

Specific implementation manner

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] Refer to Figure 1 and Figure 2 , an embodiment provided by the present utility model: a PCB board with an explosion-proof structure, including a PCB board body 1. Two placement grooves 3 are opened inside the left side of the PCB board body 1. A limiting groove 4 is opened on one side inside the placement groove 3. A return spring 5 is fixedly connected inside the limiting groove 4. One end of the return spring 5 is fixedly connected with a slide block 6. One side of the slide block 6 is fixedly connected with a push rod 7. The outside of the slide block 6 is rotatably connected with a double-headed telescopic rod 8. The other end of the double-headed telescopic rod 8 is rotatably connected with a clamping block 10. Two installation blocks 2 are fixedly connected to the right side of the PCB board body 1. Card slots 11 are opened on the sides of the two installation blocks 2 away from each other. Two installation grooves 9 are opened on the left side of the PCB board body 1. The inside of the installation groove 9 is slidably connected with the outside of the installation block 2. The middle part of the double-headed telescopic rod 8 is rotatably connected inside the placement groove 3. The outside of the clamping block 10 is engaged with the inside of the card slot 11.

[0023] Specifically, by pushing the push rod 7, the slider 6 slides inside the limit groove 4, which can exert pressure on the return spring 5 through the limit groove 4 to make it contract, and drive the double-headed telescopic rod 8 to rotate. When the double-headed telescopic rod 8 rotates, it will drive the clamping block 10 connected to the other end to move towards the inside of the placement groove 3. By inserting the two mounting blocks 2 on the right side of one PCB board body 1 into the mounting grooves 9 on the left side of another PCB board body 1 respectively, and through the return spring 5 rebounding to release elastic force and push the slider 6 to move, the clamping block 10 can be inserted into the inside of the card slot 11, thus realizing the splicing and fixing between the two PCB board bodies 1, saving the volume and weight of the overall device, helping to improve the reliability and stability of the circuit, reducing the risk of electromagnetic interference and signal crosstalk, and further enhancing the performance and working efficiency of the overall device.

[0024] Refer to Figure 3 , protective components are provided at the four corners of the upper and lower sides of the PCB board body 1. The protective components are used for protecting the PCB board body 1. The protective components include a sleeve rod 12, the sleeve rod 12 is fixedly connected to a corner of the PCB board body 1, an active rod 15 is slidably connected inside the sleeve rod 12, a limit ring 16 is fixedly connected to the outer bottom end of the active rod 15, communication grooves 13 are formed inside both the sleeve rod 12 and the active rod 15, a buffer spring 14 is fixedly connected to the inner bottom of the sleeve rod 12, a protective plate 17 is fixedly connected to the top end of the active rod 15, one end of the buffer spring 14 is fixedly connected to the inner top of the active rod 15, and the outer part of the limit ring 16 is slidably connected to the inner wall of the sleeve rod 12.

[0025] Specifically, the PCB board body 1 plays a role in supporting and fixing the sleeve rod 12 to ensure that the protective components can stably achieve the protective effect. By providing a buffer pad on the surface of the protective plate 17, the impact force can be reduced, and the protective plate 17 can receive the impact force generated during a collision, thereby pushing the active rod 15 towards the inside of the sleeve rod 12. At this time, the buffer spring 14 contracts to absorb part of the impact force and reduce the collision force, thus protecting the PCB board and preventing it from being damaged due to impact, ensuring the use safety of the PCB board. The communication groove 13 can limit the buffer spring 14 to make it contract stably, and the movement of the active rod 15 is restricted by the limit ring 16 to ensure the stable operation of the structure.

[0026] Refer to Figure 2 , the slider 6 is slidably connected inside the limit groove 4, the outer part of the return spring 5 is slidably connected to the inner wall of the limit groove 4, and one end of the push rod 7 extends to the outside of the PCB board body 1, and the outer part of the push rod 7 is slidably connected to the inside of the PCB board body 1.

[0027] Specifically, the movement of the slider 6 is restricted by the limiting groove 4, enabling the return spring 5 to contract stably without deviation. Subsequently, the push rod 7 is pushed to achieve the splicing operation between the two PCB boards 1, reducing the occupied space and enhancing the integration level.

[0028] Referring to Figure 1 , a plurality of heat dissipation holes 18 are provided on the surface of the PCB board 1, and the material of the PCB board 1 can be an epoxy resin composite material containing glass fiber.

[0029] Specifically, the heat dissipation holes 18 can enhance the heat dissipation effect of the PCB board, reduce the influence of temperature on the operation of electronic components, thereby extending the service life. Additionally, by using an epoxy resin composite material containing glass fiber, the PCB board becomes more durable and will not burst even at higher temperatures.

[0030] Working principle: When splicing the PCB boards, by pressing the push rods 7 on the front and rear sides of the PCB board 1, the push rods 7 push the sliders 6 to slide inside the limiting grooves 4, exerting pressure on the return spring 5 to make it contract, and driving the double-headed telescopic rod 8 to rotate. Subsequently, the other end of the double-headed telescopic rod 8 drives the clamping block 10 to move towards the inside of the placement groove 3. Then, the two mounting blocks 2 on the right side of another PCB board 1 can be respectively inserted into the mounting grooves 9 on the left side of the current PCB board 1. Then, release the push rod 7 to make the return spring 5 rebound, so that the clamping block 10 can be inserted into the inside of the card slot 11, thus realizing the splicing and fixation between the two PCB boards 1, saving the volume and weight of the overall device, contributing to improving the reliability and stability of the circuit, reducing the risk of electromagnetic interference and signal crosstalk, and further enhancing the performance and working efficiency of the overall device. Secondly, when the PCB board drops, the protection components at the four corners of the PCB board 1 can achieve the protection effect. When being impacted, first, the impact force is received by the protection plate 17, which then pushes the movable rod 15 to move towards the inside of the sleeve rod 12. At this time, the buffer spring 14 contracts to absorb part of the impact force, thereby protecting the PCB board and preventing it from being damaged due to impact, ensuring the use safety of the PCB board.

[0031] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
