Description of the Invention: [Technical Field] [0001] The present invention relates to a power supply fixing device, and more particularly to a power supply fixing device for use in a computer or a servo. [Prior Art] [0002] Power supply is an extremely important and indispensable component in computer systems. The conventional power supply assembly method is as follows: put the power supply into the chassis, move and close the rear panel of the chassis, and then use multiple screws to remove the chassis. The power supply is fixed to the rear panel of the chassis. As personal computers develop in the direction of lightness, thinness, and smallness, the functions are constantly being updated. This requires that the power of the power supply is getting larger and larger, and the power supply is getting heavier. Therefore, the increasingly small space in the chassis brings a lot of inconvenience to the assembly and disassembly of the power supply, and the power supply is fixed on the rear panel of the chassis, which is also a great test for the strength of the rear panel. SUMMARY OF THE INVENTION [0003] In view of the above, it is necessary to provide a power supply fixing device that is easy to assemble and disassemble and has high strength. [0004] A power supply fixing device for fixing a power supply, comprising a chassis and a support plate fixed to the chassis, the chassis includes a rear plate, and the rear plate is provided with a limit for fixing the power supply The support plate is provided with a limiting portion for supporting the power supply. Compared with the prior art, the power fixing device conveniently fixes the power supply 'reducing device' by the limiting structure and the limiting portion, and conveniently disassembles the power supply device. In addition, the limiting structure and the limiting portion can also greatly enhance the structural strength of the rear panel of the chassis.

The power supply 20 includes a top wall 21 and a side wall 23, and the side wall 23 is perpendicular to the top wall 21. The top wall 21 defines two mounting holes 212 and a plurality of bumps 213. The power fixing device includes a chassis 10 and a support plate 3 固定 fixed to the chassis 1 The bottom plate 12, a rear plate 14 and two side plates 18, 19 which are parallel to each other. The rear plate 14 and the two side plates 18, 19 are perpendicular to the bottom plate 12, and the two side plates 18, 19 are perpendicular to the rear plate 14. The support plate .'::'.:.. 30 is fixed to the bottom plate 12. The rear panel 14 defines an opening 142 near the side panel 18 and is provided with a limiting structure 14 5 for preventing the power supply 20 from moving. The limiting structure 145 includes a flap 144 and a pressing plate 146. . The flap 144 is bent away from the opening 142 and bent perpendicularly inwardly to one of the edges of the side panel 18. The pressing plate 146 is bent away from the opening 142 and bent inwardly toward one edge of the bottom plate 12, and is perpendicular to the rear plate 14. The pressure plate 146 is provided with two positioning holes 1462. - The side panel 18 is bent with a flange 182, and the pressure plate 146 can be fixed to the flange 182 by means of riveting, rivet connection, welding, screw locking or the like. The support plate 30 can be detachably fixed to the chassis 10 by means of a buckle or the like, and is provided with a reinforcing portion 36, a limiting hole 32, a positioning portion 31, two first limiting portions 33 and a The second limiting portion 35. The reinforcing portion 36 is located in the middle of the support plate 30, and includes an opening 361 and a form number Α0101. Page 5 / 13 pages 0992048089-0 [0012] 201210431 is similar in shape to the opening 361. The groove 363 connects the opening 361 and the support plate 3 (). The reinforcing portion % is used for the support plate 30. [0014] [0014] The positioning portion 31 can be fixed to the positioning portion 31 by means of riveting, rivet connection, welding, screw locking, etc. by means of such a " The method can increase (10) the support strength of the riding board 144 / the first limiting portion 33 is respectively formed by the edge of one of the slits of the supporting plate 3 to "fold" the second limiting portion 35 An edge of the limiting hole 32 adjacent to the opening 361 is bent inwardly (four). The third limiting portion 33 is adjacent to the side plate 18<the lower edge, and the two first limits P33 are in the same a line perpendicular to the rear plate 14. The second limit 卩35 is perpendicular to the rear plate 14. In a preferred embodiment, the limiting portion 35 is approximately the same as the flap 144 [0015] [0015] [0015] [0015] FIG. 2 and FIG. 3 'When the power supply 2 is mounted, the power supply 20 is pushed closer to the opening 142 toward the direction perpendicular to the rear plate 14 a power supply 20, the side wall 23 of the power supply 20 is adjacent to the folding plate 44, the top wall 21 is adjacent to the pressing plate 146, and is flush with the side And the opposite side wall (not shown) is adjacent to the side panel 18. Continue to push the power supply 20, the side wall 23 of the power supply 20 and the second limiting portion 35, and the side wall 23 parallel and opposite side walls (Fig. -, ,, Guohe) are respectively abutted against the first limiting portion 33. The power supply 20 is pushed on the folded plate 144, the pressing plate 146, The 099127383 is moved between the limiting portion 33 and the second limiting portion 35 until the mounting hole 212 of the power supply device 20 is aligned with the positioning hole 1 462 on the pressing plate 146, and the mounting hole is screwed. 212 and the positioning hole 1 462, such as the form number A〇l〇1 page 6 / total 13 page 0992048089-0 201210431 the folding plate 144, the pressure plate 146, the first limiting portion and the second The limiting portion fixes the power supply 20 to the chassis 10 and the support plate 30.
