[0002] Industrial control computers are widely used in workshops and other scenarios. There are multiple different types of interfaces on their motherboards. Among them, the PCIe*16 interface is an interface with high-speed transmission capability and is compatible with different types of PCIe boards.

[0003] The patent document with announcement number CN216927520U discloses a PCIe board card installation and fixing bracket kit, including: a fixing bracket assembly, the fixing bracket assembly includes a mounting bracket and a plurality of threaded holes opened on the mounting bracket; a board card fixing assembly, including one or more PCIE board card fixing plates, one or more PCIE board cards, a front adapter, a rear adapter and a backplane to achieve a fixing effect for PCIE; however, the internal space of an industrial computer is compact, and the bracket kit occupies a large space and is not easy to equip. At the same time, the existing industrial computer mounting bracket often fixes the board card by cooperating with screws and screw holes of the board card bracket. The entire board card is fixed by only two points, the interface and the screws, with a small fixing area, poor fixing effect, and is easily affected by vibration.

[0004] Based on this, the utility model designs a PCIe board fixing device for an industrial control computer to solve the above problems. Utility Model Content

[0008] A locating pin for locating the screw fixing hole is fixedly installed on the screw mounting plate of the mounting frame, and the flip pressure plate is hinged to the mounting frame through a hinge shaft; the flip pressure plate is crimped to the screw fixing plate of the pcie board bracket; a locking component that is clamped to the flip pressure plate is fixedly installed on the screw mounting plate of the mounting frame.

[0009] Furthermore, a torsion spring is provided on the hinge shaft, and the flip pressure plate is closed in a natural state.

[0010] Furthermore, a front pressing plate is fixedly installed at one end of the flip pressing plate close to the plug-in bonding plate, and side baffles are fixedly installed at the left and right ends of the flip pressing plate.

[0011] Furthermore, a plurality of seismic isolation blocks are arranged on the inner side of the flip pressure plate, and the seismic isolation blocks are evenly distributed.

[0012] Furthermore, the seismic isolation block is configured to be made of PU foam material.

[0013] Furthermore, the locking components are provided in two groups and are symmetrically distributed on the left and right sides of the flip pressure plate.

[0031] In the present invention, the user places the side of the pcie board bracket 200 in close contact with the plug-in fitting plate 110, aligns the socket of the pcie board with the interface and then inserts it. After insertion, the screw fixing plate 220 of the pcie board bracket 200 is fitted with the screw mounting plate 120 of the mounting frame 100, and at the same time, the screw fixing hole 210 of the pcie board bracket 200 is aligned with the positioning pin 300, so as to achieve accurate positioning of the pcie board bracket 200; flip the flip pressing plate 400 onto the screw fixing plate 220, and flip the pressing plate After 400 is fitted with the screw mounting plate 120, the locking assembly 600 locks the flip pressure plate 400, thereby pressing the screw fixing plate 220 tightly against the screw mounting plate 120 through the flip pressure plate 400, and cooperates with the positioning pin 300 to complete the rapid fixation of the PCIE board bracket 200, without the need for screw fixation, which greatly facilitates the fixation of the PCIE board. At the same time, compared with the screw fixing method, the flip pressure plate 400 has a larger fixing area for the PCIE board bracket 200, thereby having a better fixing effect.

[0032] Example 2

[0033] like Figure 1-3 As shown, as a preferred embodiment of the utility model, a torsion spring is provided on the hinge shaft 500 to close the flip pressure plate 400 in a natural state, thereby reducing the space occupied by the fixing device.

[0034] The flip pressing plate 400 is fixedly installed with a front pressing plate 410 at one end close to the plug-in bonding plate 110, and side baffles 420 are fixedly installed at the left and right ends of the flip pressing plate 400. The front pressing plate 410, the side baffles 420 and the positioning pins 300 cooperate to fix the pcie board bracket 200;

[0035] A plurality of isolation blocks 430 are arranged on the inner side of the flip pressure plate 400, and the isolation blocks 430 are evenly distributed, so as to reduce the vibration of the machine body transmitted to the pcie board bracket 200 through the mounting frame 100, thereby reducing the risk of damage to the board.

[0036] The seismic isolation block 430 is made of PU foam material.

[0037] Example 3

[0041] In the present invention, when the flip pressure plate 400 is flipped and pressed toward the screw mounting plate 120, the flip pressure plate 400 pushes the card plate 610 through the guide slope 611. When the flip pressure plate 400 reaches the set position, the flip pressure plate 400 no longer blocks the card plate 610, and the locking spring 620 drives the card plate 610 to reset, and finally the flip pressure plate 400 is clamped through the clamping plane 612, so that the flip pressure plate 400 presses the screw fixing plate 220 tightly against the screw mounting plate 120, thereby completing the rapid fixation of the pcie board bracket 200.
