[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-7 As shown, a circuit board with a novel assembly structure includes a backing plate 1. A circuit board body 2 is mounted on the backing plate 1 via a fixing structure 3. The fixing structure 3 includes a sliding groove 301. Sliding grooves 301 are formed on both sides of the backing plate 1. A sliding sleeve 302 is slidably connected within the sliding groove 301. A screw 304 is rotatably connected to the sliding sleeve 302. A slider 303 is threadedly connected to the end of the screw 304. The slider 303 is slidably connected to the sliding sleeve 302. The bottom end of the slider 303 abuts against the circuit board body 2. A retaining strip 4 is fixedly connected to both sides of the backing plate 1. Multiple heat sinks 6 are mounted on the circuit board body 2. A limiting structure 7 is mounted on the backing plate 1.

[0025] As a technical optimization of this utility model, two guide rods 305 are fixedly connected to both sides of the liner 1. The two sliding sleeves 302 are slidably connected to the two guide rods 305 on the same side. A spring 307 is sleeved on the outside of the guide rod 305. One end of the spring 307 is fixedly connected to the sliding sleeve 302, and the other end of the spring 307 is fixedly connected to the liner 1. An anti-detachment block 306 is fixedly connected to the end of the guide rod 305. The end of the sliding sleeve 302 has an inclined structure. The sliding sleeve 302 slides along the horizontal direction of the liner 1, and the slider 303 slides along the vertical direction of the liner 1. The guide rods 305 guide the sliding of the sliding sleeve 302, and the anti-detachment block 306 prevents the sliding sleeve 302 from slipping off the liner 1.

[0026] As a technical optimization of this utility model, the cross-section of the clip 4 is trapezoidal, and the bottom end of the liner 1 is provided with multiple through slots 5. After the circuit board body 2 is fixed on the liner 1, the clips 4 on both sides of the liner 1 are engaged into the slots on the housing, thereby quickly completing the installation of the circuit board body 2. By engaging the standard thickness clips 4 with the slots on the housing, circuit board bodies 2 of different thicknesses can be assembled into the housing. The through slots 5 and heat sinks 6 enhance the heat dissipation effect of the circuit board body 2.

[0027] As a technical optimization of this utility model, the limiting structure 7 includes a limiting rod 701. The limiting rod 701 is slidably connected to one side of the liner 1. A limiting hole 702 is formed on the sliding sleeve 302 on the same side. The end of the limiting rod 701 engages with the limiting hole 702. A stop block 703 is fixedly connected to the end of the limiting rod 701 that engages with the limiting hole 702. A through hole 705 is formed at the other end of the limiting rod 701. A tension spring 704 is sleeved on the limiting rod 701. One end of the tension spring 704 is fixedly connected to the liner 1, and the other end of the tension spring 704 is fixedly connected to the limiting rod 701. To facilitate the installation and removal of the circuit board body 2, when the circuit board body 2 is not placed on the liner 1, the sliding sleeve 302 on the other side of the liner 1 is open. The circuit board body 2 is limited and housed in the groove 301 within the liner 1 by the limiting structure 7. After the circuit board body 2 is placed on the liner 1, the wrench is inserted into the through hole 705 and the limiting rod 701 is pulled upward, causing the limiting rod 701 to slide upward and simultaneously driving the tension spring 704 to extend. This prevents the end of the limiting rod 701 from engaging with the limiting hole 702 on the same side of the sliding sleeve 302. At this time, the spring 307 resets and drives the sliding sleeve 302 and the slider 303 to slide outward from the liner 1, and the slider 303 abuts against the upper end face of the circuit board body 2. Thus, the circuit board body 2 of different thicknesses is fixed by the cooperation of the sliding sleeves 302 and the slider 303 on both sides of the liner 1, so that the circuit board body 2 of different thicknesses can be adapted to the outer shell and the circuit board body 2 is installed stably and firmly.

[0028] As a technical optimization of this utility model, four positioning posts 8 are fixedly connected to the bottom end of the circuit board body 2, and four positioning holes 9 are opened on the liner plate 1. The positioning posts 8 are inserted into the positioning holes 9. The positioning posts 8 at the bottom end of the circuit board body 2 are aligned with the positioning holes 9 on the liner plate 1, and the circuit board body 2 is pressed down to make the positioning posts 8 insert into the positioning holes 9, thereby accurately positioning the circuit board body 2.

[0029] In use, this invention first adjusts the height of the slider 303 according to the thickness of the circuit board body 2 to be installed. A hexagonal wrench is inserted into the head of the screw 304 and rotated, causing the screw 304 to drive the slider 303 vertically along the groove in the sleeve 302 via the thread. This adjusts the distance between the bottom of the slider 303 and the liner plate 1, facilitating the liner plate 1 to fix circuit board bodies 2 of different thicknesses. Next, the positioning post 8 at the bottom of the circuit board body 2 is aligned with the positioning hole 9 on the liner plate 1, and the circuit board body 2 is pressed down to engage the positioning post 8 with the positioning hole 9, thereby fixing the circuit... The circuit board body 2 is precisely positioned. During the downward movement of the circuit board body 2, due to the inclined structure of the end of the sliding sleeve 302, the side of the circuit board body 2 facing away from the limiting rod 701 abuts against the sliding sleeve 302 on the same side, sliding towards the inside of the liner plate 1. Simultaneously, the sliding sleeve 302 slides, causing the spring 307 to contract. When the circuit board body 2 moves downward until its height is lower than the height of the slider 303, the spring 307 resets and drives the sliding sleeve 302 and slider 303 to slide towards the outside of the liner plate 1, thereby causing the bottom end of the slider 303 to press firmly against the circuit board body 2 downwards. This facilitates the installation and removal of the circuit board body 2. When the circuit board body 2 is not placed on the backing plate 1, the sliding sleeve 302 on the other side of the backing plate 1 is limited by the limiting structure 7 and housed in the sliding groove 301 inside the backing plate 1. When the circuit board body 2 is placed on the backing plate 1, the wrench is inserted into the through hole 705 and the limiting rod 701 is pulled upward, causing the limiting rod 701 to slide upward and simultaneously driving the tension spring 704 to extend, so that the end of the limiting rod 701 is no longer engaged with the limiting hole 702 on the sliding sleeve 302 on the same side. At this time, the spring 307 returns to its original position and drives the sliding sleeve 302 and the slider 303 to slide outward from the backing plate 1, and the slider 303 abuts against the upper end surface of the circuit board body 2. The sliding sleeves 302 on both sides of the liner 1 and the slider 303 are used to fix the circuit board body 2 of different thicknesses, so that the circuit board body 2 of different thicknesses can be adapted to the outer shell and the circuit board body 2 is installed stably and firmly. After the circuit board body 2 is fixed on the liner 1, the clips 4 on both sides of the liner 1 are engaged into the slots on the shell, so as to quickly complete the installation of the circuit board body 2. By the standard thickness clips 4 engaging with the slots on the shell, the circuit board body 2 of different thicknesses can be assembled into the shell. The through slots 5 and heat sinks 6 enhance the heat dissipation effect of the circuit board body 2.
