Detailed Implementation

[0027] 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.

[0028] This specific embodiment is a computer motherboard fixing device, the structural diagram of which is shown below. Figure 1 and Figure 2 As shown, it includes:

[0029] The main body 1 has multiple first through holes 8 for fixed installation.

[0030] The top of the fixed plate 2 is detachably fixed with multiple support rods 7 corresponding to the first through hole 8;

[0031] The load-bearing plate 3 has two sets of supports fixed to the top surface of the fixed plate 2 on both sides. The top of the load-bearing plate 3 has a support part 17 located below the main body 1, and multiple fans 4 are embedded and fixed in the center of the load-bearing plate 3.

[0032] The top of the fixing plate 2 is fixed with multiple screws 10 corresponding to the first through holes 8. The bottom end of the support rod 7 is threaded onto the screw 10. Both the support rod 7 and the load-bearing plate 3 are rigid structures, preferably made of high-strength and insulating PVC plastic. When the support rod 7 is damaged, it can be unscrewed from the screw 10 for replacement. The fixing plate 2 has a rectangular array of second through holes 13. The second through holes 13 are embedded with second bolts 11 that are threaded into the inner wall of the computer host. The top of the support rod 7 is fixed with a threaded tube 12. The top of the motherboard body 1 is equipped with multiple first bolts 6. The bottom end of the first bolts 6 passes through the motherboard body 1 and is threaded into the threaded tube 12.

[0033] like Figure 3 and Figure 4 As shown, a hollow groove 9 is provided at the center of the load-bearing plate 3. The fan 4 is embedded and fixed in the hollow groove 9. The fans 4 in the two load-bearing plates 3 rotate in the same direction. The cooling air flows between the two load-bearing plates 3 and the motherboard body 1, so that one set of fans 4 intakes air and the other set of fans 4 exhausts air. A protective net 5 is fixed to the side wall of the hollow groove 9. The protective net 5 can block dust inside the computer body. Both ends of the motherboard body 1 are provided with grooves 16. A positioning part 15 that fits into the groove 16 is fixed on one side of the top surface of the support part 17. The positioning part 15 is inserted into the groove 16 so that the motherboard body 1 is stably locked between the two load-bearing plates 3 during installation, so that the first bolt 6 can easily pass through the first through hole 8 and be threaded into the threaded tube 12. A protrusion 14 is fixed to the top of the positioning part 15. The two protrusions 14 are inclined at their close ends. The inclined surface on the protrusion 14 makes it easy for the motherboard body 1 to be inserted between the two load-bearing plates 3.

[0034] Working principle: When using the device of this technical solution, multiple support rods 7 are threaded onto the screw 10, so that the motherboard body 1 is inserted between two load-bearing plates 3. The positioning part 15 at the top of the load-bearing plate 3 is embedded in the groove 16. The bottom end of the main body is in contact with the support part 17. The motherboard body 1 is fixed to the support rods 7 by the threaded insertion of the first bolt 6 into the threaded tube 12. The support rods 7 and the load-bearing plates 3 make a heat dissipation cavity between the fixing plate 2 and the motherboard body 1. The fan 4 in the load-bearing plate 3 makes the air flow in the heat dissipation cavity at the bottom of the motherboard body 1, thereby improving the heat dissipation effect at the bottom of the computer body.

[0035] All technical features in this embodiment can be freely combined according to actual needs.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
