[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0031] Embodiment 1:

[0032] The present invention solves the problem that the existing circuit board is installed by screws, and the screws need to be rotated to achieve the fixing effect during installation. The efficiency of the rotation of the screws through the threads is slow, which will lead to a long time-consuming for installing the circuit board. By forming a snap fit between the slider 5 and the chute 6, the installation efficiency of the circuit board body 1 is improved, and the following is disclosed:

[0033] The circuit board body 1 has components soldered on its surface. It further includes: a fixing pin 2 slides at an equal angle on the circuit board body 1, and a latching mechanism is formed between the fixing pin 2 and the circuit board body 1. The bottom of the fixing pin 2 extends into the inside of the connecting column 3 to form a sliding mechanism. The bottom of the connecting column 3 extends into the inside of the mounting plate 4, and a slider 5 is fixed at the bottom of the connecting column 3. The outer end of the slider 5 extends into the inside of the chute 6 to form a latching mechanism, and the chute 6 is opened inside the mounting plate 4;

[0034] Reference Figures 1 to 5 , by rotating the fixing pin 2, the fixing pin 2 can rotate on the circuit board body 1. The rotation of the fixing pin 2 drives the connecting column 3 to rotate, so that the connecting column 3 rotates and slides inside the mounting plate 4. Then, the rotation of the connecting column 3 drives the slider 5 to slide inside the chute 6. After the fixing pin 2 rotates to a position, a latching mechanism is formed between the slider 5 and the chute 6, and then the circuit board body 1 can be quickly installed on the mounting plate 4. And through reverse rotation, the circuit board body 1 can be conveniently disassembled, thus improving the installation efficiency;

[0035] Embodiment Two:

[0036] The present utility model solves the problem that the latching between the slider 5 and the chute 6 in Embodiment One is not stable enough. The stability of the latching between the slider 5 and the chute 6 can be improved by the latching between the convex block 7 and the groove 8, and discloses:

[0037] A convex block 7 slides inside the slider 5, and the outer end of the convex block 7 is semicircular. The outer end of the convex block 7 extends into the inside of the groove 8 to form a latching mechanism, and the groove 8 is opened inside the mounting plate 4. The inner end of the convex block 7 is connected to a first spring 9, and the inner end of the first spring 9 is connected inside the slider 5;

[0038] Reference Figures 1 to 5 , by the rotation of the slider 5 driving the convex block 7 to rotate, then the rotation of the convex block 7 causes extrusion with the groove 8, so that the convex block 7 is extruded and slides into the inside of the slider 5. The sliding of the slider 5 will squeeze the first spring 9, then the first spring 9 is compressed under force, and then the convex block 7 is disengaged from the latching of the groove 8, so as to facilitate the sliding of the slider 5 inside the chute 6. By reversing the above operation, then the first spring 9 can push the convex block 7 to extend into the inside of the groove 8 to form a latching, so that the slider 5 can be stably fixed inside the chute 6;

[0039] Embodiment Three:

[0040] The utility model solves the problem that the length of the screw needs to be adjusted according to the height of different components to avoid extrusion. By rotating the pawl 10, the purpose of adjusting the height can be achieved, thus avoiding extrusion, and discloses:

[0041] The bottom of the fixing pin 2 is rotatably connected with a pawl 10, and the outer end of the pawl 10 extends into the inside of the clamping groove 11 to form a one-way clamping mechanism. The clamping grooves 11 are equally spaced inside the connecting column 3. The inner end of the pawl 10 is connected with a second spring 12, and the inner end of the second spring 12 is connected inside the fixing pin 2. A pull rope 13 is connected inside the pawl 10, and the top of the pull rope 13 extends out of the inside of the fixing pin 2 through a roller 14 to form a sliding mechanism, and the roller 14 is connected to the inside of the fixing pin 2 through a bearing;

[0042] Reference Figure 2 、 Figure 6 And Figure 7 According to different usage requirements, components need to be welded on the circuit board body 1. To avoid extrusion caused by components of different heights, the circuit board body 1 can be pulled, so that the circuit board body 1 drives the fixing pin 2 to slide inside the mounting plate 4. The movement of the fixing pin 2 drives the pawl 10 to move, so that the movement of the pawl 10 will be squeezed by the clamping groove 11, and then the pawl 10 is rotated into the inside of the fixing pin 2 under the extrusion, so that the rotation of the pawl 10 will squeeze the second spring 12, and then the second spring 12 is compressed under force. After adjusting to the appropriate height, the second spring 12 drives the pawl 10 to extend into the inside of the clamping groove 11 to form a clamping, so as to achieve the purpose of adjusting the height, and then there is a gap between the components on the circuit board body 1 and the mounting plate 4, so as to facilitate the heat dissipation of the components on the circuit board body 1. By pulling the pull rope 13, the pull rope 13 moves to drive the pawl 10 to rotate through the roller 14, so that the pawl 10 will disengage from the clamping of the clamping groove 11, and then the fixing pin 2 can be reset inside the connecting column 3.

[0043] Working principle: When using a mounting structure for a circuit board, first, reference Figures 1 to 5 , by rotating the fixing pin 2, the fixing pin 2 can rotate on the circuit board body 1, and the rotation of the fixing pin 2 drives the connecting column 3 to rotate. Then, the rotation of the connecting column 3 drives the slider 5 to slide inside the chute 6. After the fixing pin 2 rotates to the position, a clamping mechanism is formed between the slider 5 and the chute 6, and through reverse rotation, the circuit board body 1 can be conveniently disassembled, thus improving the installation efficiency;

[0044] Reference Figures 1 to 5, the rotation of the slider 5 drives the rotation of the convex block 7. Subsequently, the rotation of the convex block 7 causes extrusion with the groove 8. When the slider 5 slides, it will extrude the first spring 9, causing the first spring 9 to be compressed under force. Then, the convex block 7 disengages from the engagement with the groove 8. By reversing the above operations, the first spring 9 can push the convex block 7 into the interior of the groove 8 to form an engagement, so that the slider 5 can be stably fixed inside the chute 6;

[0045] Reference Figure 2 , Figure 6 and Figure 7 , according to different usage requirements, components need to be soldered on the circuit board body 1. Then, the circuit board body 1 can be pulled, causing the circuit board body 1 to drive the fixing pin 2 to slide inside the mounting plate 4. The movement of the fixing pin 2 drives the movement of the pawl 10. Subsequently, the pawl 10 is squeezed and rotates into the interior of the fixing pin 2, causing the second spring 12 to be compressed under force. After adjusting to the appropriate height, the force of the second spring 12 drives the pawl 10 to extend into the interior of the card slot 11 to form an engagement. Subsequently, there is a gap between the components on the circuit board body 1 and the mounting plate 4. By pulling the pull rope 13, the movement of the pull rope 13 drives the rotation of the pawl 10 through the roller 14, and then the fixing pin 2 can be reset inside the connecting column 3.
