Description of the Invention: [Technical Field] The present invention relates to a locking device, and more particularly to an expansion card locking device. [Prior Art] In order to realize multimedia functions, a computer needs to open a plurality of expansion slots such as a Peripheral Component Interconnect slot and an AGP (Accelerate Graphical Port) slot. By plugging an expansion card such as a video card, sound card, or network card into an expansion slot or replacing a graphics card, sound card, or network card inserted in the expansion slot, the computer can perform its corresponding functions. In order to prevent the expansion card installed on the expansion slot of the computer motherboard from loosening or falling off when the computer is moved or accidentally impacted, the expansion card is usually fixed to the expansion card fixing plate, and then the expansion card fixing plate is fixed on the computer chassis. . In the conventional fixing method, screws are usually used to fix the expansion card fixing plate. For example, referring to Fig. 1, a conventional expansion card fixing device includes a solid plate 11 and a plurality of screws. An expansion slot (not shown) is defined in the chassis 13, and a flange 132 is protruded from the edge of the expansion slot toward the inside of the chassis 13. The expansion card fixing plate 14 has an elongated shape, and its end is provided with a bent edge that is engaged with the convex edge 132 of the chassis 13. When the expansion card is fixed, the fixing plate 11 is pressed against the bent side of the expansion card fixing plate 14, and the fixing piece n is fixed to the chassis 13 by the screw 12, thereby fixing the expansion card fixing plate 14. However, for the computer production line, the screws 12 need to be screwed into the corresponding threaded holes one by one, which is inconvenient to assemble and has low production efficiency; and the computer terminal uses 200930239. When the field needs to be replaced, the fixing method of the screw is also inconvenient for assembly and replacement. In the process of disassembly and assembly, tools such as a screw lifter must be used, which is not in line with the 'toollessness' of the computer installation; After repeated use for a long period of time, the screw 12 and the corresponding screw hole may be worn out, which may cause problems such as inability to be effectively fixed and fixed after being fixed. [Summary of the Invention] In the above, it is necessary to provide an easy disassembly and assembly without the need for sputum. Other tools can realize the disassembly and assembly of the expansion card locking device. An expansion card locking device for locking the expansion card with the expansion card fixing plate to the chassis, the locking device includes a pressing member and a pressing And a first elastic member for & for the torque, the pressing member is used for pressing the expansion card fixing plate in the locked state of the locking device, so that the expansion card fixing plate is opposite to the chassis port, and is rotatable relative to the chassis The first elastic member is fixedly connected to the pressing member at one end, and the other end is fixed to the chassis. The pressing member is slidable relative to the chassis, and the pressing member is used for abutting against the pressing member in the locked state of the locking device. The pressing member ◎ is non-rotatable and is used for moving relative to the chassis when unlocking, thereby releasing the abutment against the pressing member, causing the pressing member to rotate under the action of the first elastic member, and the first elastic member is stored in the locked state of the locking device. In view of the above, in the expansion card locking device of the present invention, it is not necessary to use a screw to lock, and only the pusher can be pushed to realize the locking and unlocking operation of the expansion card fixing plate and the chassis. In the process of disassembly and assembly, it is not necessary to use tools such as a screw lifter to truly realize the “toolless” installation of the computer. μ [Embodiment] 200930239 The expansion card locking device of the present invention will be further developed with reference to the accompanying drawings and embodiments.

The card is fixed to the board 22. 200930239 The expansion card locking device 30 includes a pressing member 32, a pressing member 34, two fixing members 36, two torsion springs 37 and two springs 38. The abutting member 32 is elongated and has a length substantially equivalent to the length of the rib 244 on the chassis 24 in which the projections 246 are provided. A locking hole 326 and a pivot hole 328 are respectively defined at two ends of the pressing member 32. The pressing member 34 is a hollow housing, and includes a body 342 and two lugs 344 respectively disposed at opposite ends thereof. The length of the body 342 is also substantially equivalent to the length of the ribs 244 on the chassis 24 that are provided with protrusions 246. Each lug ® 344 is generally a rectangular housing having a post 346 having an axis that is perpendicular to the length of the body 342. The body 342 is recessed with a recess 348 for facilitating the operation of the pressing member 34. A slider 349 is also provided at the edge of each lug 344. The fixing member 36 has a substantially rectangular parallelepiped shape, and a recess 364 is defined on one side of the fixing member 36. A bottom of the recess 364 extends from a shaft 366 and defines a fixing hole 367. The other side of the fixing member 36 adjacent to the side of the opening recess 364 defines a receiving groove 368 for receiving the spring 38, and the sliding piece 349 of the pressing member 34 slidably extends into the receiving groove 368. . The torsion spring 37 is configured to provide a torsion force, and includes a first fastening end 372 fixedly inserted into the fastening hole 326 of the pressing member 32 and a second fixing end fixedly inserted into the fixing hole 367 of the fixing member 36. 374. The spring 38 is a compression spring that is received in the receiving groove 368 of the fixing member 36, and one end of the spring 38 is sleeved on the protruding post 346 of the pressing member 34 and abuts against the end of the lug 344, and the other end abuts the fixing member 36. The side wall of the slot 368 is received. Referring to FIG. 4, when the expansion card locking device 30 is assembled, the rotating shaft 366 of the fixing member 36 is first inserted into the coil of the torsion spring 37 and the pivot hole 200930239 328 of the pressing member 32, and the pressing member 32 is relatively fixed. 36 is rotated around the axis of the rotating shaft 366; the two ends of the pressing member 34 are respectively disposed adjacent to the two fixing members 36, and the sliding piece 349 of the pressing member 34 is corresponding to the receiving groove 368 of the fixing member 36, and The two springs 38 are respectively inserted into the receiving grooves 368 of the two fixing members 36, and the two ends of the spring 38 respectively abut the pressing member 34 and the fixing member 36; finally, the fixing member 36 is fixed to the chassis 24 to open the receiving groove 368. One side is attached to the chassis 24 and the expansion card locking device 30 is adjacent to the slot 242 of the chassis 24 such that the pressing member 32 can just press against the protrusion 246 of the chassis 24 After the assembly is completed, the pressing member 34 can slide along the receiving groove 368 relative to the fixing member 36. When the expansion card is mounted on the chassis 24, the insertion end 228 of the expansion card fixing plate 22 is firstly fitted to one of the protrusions 248 of the chassis 24, and each protrusion 246 of the chassis 24 is respectively inserted into one of the expansion card fixing plates 22. Corresponding to the missing groove 226, the expansion card fixing plate 22 is restricted from moving arbitrarily in the plane of the fixing portion 224 thereof. And one side of the pressing member 32 is engaged with the upper surface of the 0 fixing portion 224 of the expansion card fixing plate 22, thereby restricting the expansion card fixing plate 22 from moving in the direction perpendicular to the fixing portion 224 thereof. At this time, the torsion spring 37 is in a state of being twisted and storing the elastic potential energy, and the spring 38 is in a natural state. The pressing member 34 is located behind the pressing member 32 and abuts against the edge of the pressing member 32, so that the pressing member 32 cannot be rotated. Referring to FIG. 5, when the expansion card needs to be installed or removed, the operator places the hand on the groove 348 of the pressing member 34 and pulls the pressing member 34 toward the fixing member 36 away from the slot 242 of the chassis 24.
