[0039] The present application discloses a tool-free PCIE fixing device, please refer to Figures 1-8 which comprises a Riser module support 1, a PCIE card connecting piece 4, and a card pressing fixing piece 2.

[0040] PCIE card connector 4 is used to fix the PCIE card, the die casting 3 is in an upright state and is fixed to one side of the Riser module support 1 in the width direction; the die casting 3 is in an upright state and is pivotally connected to one side of the Riser module support 1 in the width direction; the inner side of the die casting 3 is provided with a clamping piece 21, the die casting 3 is provided with a clamping hole 32 which is elastically clamped with the clamping piece 21, and the PCIE card connector 4 is provided with a clamping slot 421 through which the clamping piece 21 passes; when fixed, the die casting 3 is rotated inward to make the outer end of the clamping piece 21 pass through the clamping slot 421 and then be clamped into the clamping hole 32, so as to limit and fix the PCIE card; when the fixing is released, the die casting 3 is rotated outward to make the clamping piece 21 be separated from the clamping hole 32, so as to release the limiting and fixing of the PCIE card.

[0041] Figure 1 In order to release the limiting and fixing state of the PCIE card, Figure 2 In order to limit and fix the PCIE card, Figure 1 And Figure 2 It can be seen that the releasing and fixing of the PCIE card or the fixing and releasing of the PCIE card do not need to use a screw or a screwdriver and the like, and the use is convenient. Moreover, the die casting 3 and the die casting 3 are in an upright state along the Riser module support 1, and can be made very thin, so that the space occupied by the die casting 3 and the die casting 3 in the width direction of the Riser module support 1 is small, and the die casting 3 and the die casting 3 are clamped and matched, so that the PCIE card can be quickly fixed, the tool-free installation of the PCIE card is realized, the operation is simple, and the maintenance is convenient.

[0042] Further, please refer to Figure 5 A torsional spring installation slot 31 is formed in the die casting 3, and a torsional spring 311 is installed in the torsional spring installation slot 31. After the torsional spring 311 is installed in the torsional spring installation slot 31, the two torsional arms of the torsional spring 311 are parallel, and the interval width between the two torsional arms is less than the width of the clamping hole 32. The purpose of this design is to realize elastic clamping, that is, when the PCIE card needs to be fixed, the clamping of the outer end will cause the two torsional arms of the torsional spring 311 to be temporarily elastically deformed and opened, and after clamping, since the interval width between the two torsional arms is less than the width of the clamping hole 32 under the action of no external force, the clamping piece 21 can be clamped by the torsional spring 311. When the PCIE card needs to be released, the two torsional arms of the torsional spring 311 are elastically deformed and opened again, and the clamping piece 21 is separated from the torsional spring 311. The use of the torsional spring 311 to fix the clamping piece 21 not only facilitates use, but also will not be damaged even if used for a long time.

[0044] In some embodiments, please refer to Figure 3 The Riser module support 1 comprises the first connecting plate 15 and the second connecting plate 16 connected with each other, when the PCIE card 100 is installed in the Riser module support 1, the length direction of the first connecting plate 15 corresponds to the length direction of the PCIE card 100, and the length direction of the second connecting plate 16 corresponds to the width direction of the PCIE card 100; the end face of the end of the second connecting plate 16 away from the first connecting plate 15 serves as the fixed panel 11. The press-clamping fixing member 2 is pivotally connected to the fixed panel 11, the press-clamping fixing member 3 is fixed to the inner side of the fixed panel 11, and the fixed panel 11 is provided with the through hole 13 at the position corresponding to the clamping hole 32. In order to facilitate the clamping member 21 to pass through, preferably, the through hole 13 is designed as a waist-shaped through hole 13.

[0045] By directly using part of the Riser module support 1 as the fixed panel 11, there is no need to additionally design, and the structure design is ingenious.

[0046] In some embodiments, please refer to Figure 3 The first round 12 is arranged on the side edge of the fixed panel 11, the second round 22 matched with the first round 12 is arranged on the side edge of the press-clamping fixing member 2, and the first round 12 and the second round 22 are connected by the pin 5. By using the combination of the round and the pin 5, the originally tight width direction space of the Riser module support 1 is not occupied.

[0047] In some embodiments, please refer to Figure 8 The PCIE card connecting member 4 comprises a fixed portion 41 and a matching portion 42; the fixed portion 41 is fixed to one side of the PCIE card 100 in the width direction, the matching portion 42 is connected with the fixed portion 41 perpendicularly, the matching portion 42 is located outside the fixed panel 11 and keeps parallel with the fixed panel 11, the clamping groove 421 is arranged on the matching portion 42, and the opening direction of the clamping groove 421 is upward. Of course, in other embodiments, the clamping groove 421 can be replaced by a hole, but the clamping groove 421 is preferred, and the form of the clamping groove 421 is more convenient for disassembly and assembly.

[0048] In some embodiments, please refer to Figure 3The outer side of the fixed panel 11 is provided with a positioning protrusion 14 at the edge of the through hole 13, the outer shape of the positioning protrusion 14 is adapted to the outer shape of the clamping groove 421, so that the clamping groove 421 can be clamped on the outer side of the positioning protrusion 14. The positioning protrusion 14 is provided with the characteristics of facilitating the positioning of the PCIE card connector 4.

[0049] In some embodiments, the clamping piece 21 is movably connected to the clamping fixed piece 2, that is, it can move forward and backward, and the distance from the outer end of the clamping piece 21 to the plane of the clamping fixed piece 2 can be adjusted according to needs.

[0050] In some embodiments, the clamping piece 21 is movably connected to the clamping fixed piece 2, that is, it can move forward and backward, and the distance from the outer end of the clamping piece 21 to the plane of the clamping fixed piece 2 can be adjusted according to needs. For example, if it is not necessary to frequently release the fixation of the PCIE card 100 after clamping, the clamping piece 21 can be prevented from being easily separated from the two torsion arms of the torsion spring 311 by tightening the knob. Specifically, the position of the adjusting screw is located on the side surface of the clamping piece 3, the side surface of the clamping piece 3 is provided with a connecting hole which is aligned with the clamping hole 32, the connecting hole is internally threaded, and the surface of the adjusting screw is externally threaded.
