The Riser module bracket 1 is provided with a clamping member 1211, the pressing and clamping member is provided with a clamping hole 22 (the shape of the clamping hole 22 can be determined according to actual requirements, and preferably, a circular hole or a square hole is selected), and the PCIE card bracket 3 is provided with a clamping groove 321 for the clamping member 1211 to pass through. During fixing, the card pressing fixing member is rotated inward to clamp the card 1211 with the card hole 22 so as to limit and fix the PCIE card 100, and when the fixing is released, the card pressing fixing member is moved upward to disengage the card 1211 from the card hole 22 so as to release the limit and the fixation of the PCIE card 100.

Fig. 1 shows a state where the limit fixation of the PCIE card 100 is released, and fig. 2 shows a state where the limit fixation of the PCIE card 100 is released, and as can be seen from fig. 1 and fig. 2, no tool such as a screw or a screwdriver is needed to release the fixation of the PCIE card 100 to the fixed state or from the fixed state to the released state, which is convenient to use. After the fixing, the axis of the clip 1211 is dislocated from the axis of the clip hole 22, so that the clip 1211 is not separated from the clip hole 22 even if the clip 1211 is directly pulled outward to press the clip fixing member, thereby improving the stability of the limiting and fixing. In addition, the pressing and clamping fixing pieces are arranged along the vertical state of the Riser module bracket 1 and can be made to be very thin, so that the space occupied by the Riser module bracket 1 in the width direction is very small.

As shown in fig. 6, the clip 1211 is tapered, a bayonet 12111 is provided at a middle portion of the clip 1211, and a chamfered surface 12112 is provided at a front end of the clip 1211. When the fixing is performed, the designed chamfered surface 12112 can ensure that the clip 1211 can be smoothly clipped into the clip hole 22 of the clip fixing plate 2, after the fixing is performed, the bayonet 12111 of the clip 1211 can clip the edge of the clip hole 22, and at this time, the axis of the clip 1211 and the axis of the clip hole 22 are dislocated, so that the clip fixing member is directly pulled outwards, the clip 1211 cannot be separated from the clip hole 22, the stability of the limiting fixing is further improved, and the structural design is ingenious.

In some embodiments, the clip 1211 is directly fixed to the fixed panel 121, i.e., is not movable relative to the fixed panel 121. Of course, it is also possible to form a hole on the fixing panel 121 and to clip the clip 1211 in the opened hole, and at this time, the structure clip 1211 is rotatable relative to the fixing panel 121, so that when an external force is applied to the clip fixing plate during fixing, the clip 1211 is rotated, and is more easily clipped into the clip hole 22.

Of course, in some embodiments, for convenience of processing, a die-casting plate may be designed, and the snap 1211 may be designed on the die-casting plate, and when mounting, the die-casting plate is mounted and fixed on the rear side of the fixing panel 121, and the fixing panel 121 is designed to have a through hole for the die-casting to pass through.

As shown in fig. 3 and 4, two first beads 1212 are disposed on the side edge of the fixing panel 121, the two first beads 1212 are spaced from each other up and down, a second bead 21 is disposed on the side edge of the card pressing fixing member, the second bead 21 is located between the two first beads 1212, and the two first beads 1212 and the second bead 21 are connected by the pin member 6; the latch member 6 is sleeved with a spring 4, and the spring 4 is located between the first rolling circle 1212 and the second rolling circle 21. When the fixing is completed, the spring 4 has a downward elastic force to prevent the pressing and fixing plate 2 from moving upward, so as to prevent the clip 1211 from coming out of the clip hole 22.

Preferably, the latch member 6 may be a pin. The pins can be directly purchased in the market, additional processing is not needed, and the die sinking cost is saved.

In some embodiments, the latch member 6 is further sleeved with washers 5, and the washers 5 are located at both ends of the spring 4. The function of the added washer 5 is to prevent the spring 4 from falling into the gap due to the installation gap between the latch piece 6 and the bead, resulting in a defective function.

As shown in fig. 3 and 4, the inner side surface of the card pressing and fixing member is provided with an elastic member 23 protruding inward. Specifically, the elastic member 23 is in the shape of a curved elastic arm, one end of which is fixedly connected to the press block fixing member, and the other end of which is in a suspended state. Due to the design of the elastic piece 23, when the fixing is required to be released, the card pressing fixing piece only needs to be moved upwards for a certain distance, the card pressing fixing piece can automatically spring outwards under the elastic force action of the elastic piece 23, unnecessary time is not wasted in the fixing releasing process, and the efficiency is further improved.

As shown in fig. 3, the fixing panel 121 is provided with a stop portion 1213 extending between the two first rolling circles 1212 for limiting the pressing and fastening member. When releasing the fixing, the fixing plate 2 is slid upward by hand until it touches the stop portion 1213, at which time the hand stops applying the upward force, and the elastic member 23 has an outward elastic force due to the elastic member 23 on the fixing plate 2, and when the hand stops applying the force, the force generated by the elastic member 23 instantly springs the fixing plate 2 outward. When the fixed operation is being relieved in the design when the benefit of stopper portion 1213, upwards promote to press the card fixed plate 2 distance to have the limiting action, avoid upwards promoting the too big spring 4 that leads to of the distance that presses the card fixed plate 2 to be compressed and lose elasticity by the transition, have certain guard action to spring 4.

Of course, in other embodiments, the slot 321 may be replaced by a hole, but preferably, the slot 321 is in the form of a slot 321, which is more convenient to disassemble and assemble. After the fixing, the engaging portion 32 is equivalent to be sandwiched between the fixing panel 121 and the press block fixing plate, and at this time, the engaging portion 32 is limited, which is equivalent to that the PCIE card 100 is also limited (because the engaging portion 32 is vertically connected to the fixing portion 31, the fixing portion 31 is fixed on a side surface of one side in the width direction of the PCIE card 100).

While the invention has been described with reference to specific embodiments, the invention is not limited thereto, and various equivalent modifications and substitutions can be easily made by those skilled in the art within the technical scope of the invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
