The first structural member 1 can be a network card, and the second structural member 2 can be an antenna head. The first structural member 1 and the second structural member 2 are connected.

[0033] The board fixing structure comprises a fixing member 4, a pressing member 3 and a locking mechanism. The fixing member 4 can be plate-shaped or block-shaped. The pressing member 3 can be plate-shaped or block-shaped. The pressing member 3 is rotationally connected with the fixing member 4 through a rotating shaft mechanism, so that the pressing member 3 can rotate relative to the fixing member 4. The locking mechanism is arranged on the rotating shaft mechanism, so that when the first structure 1 and the second structure 2 are arranged between the pressing member 3 and the fixing member 4, the locking mechanism is locked. When the first structure 1 and the second structure 2 are connected, they can be arranged between the pressing member 3 and the fixing member 4. After the locking mechanism is locked, the first structure 1 and the second structure 2 can be fixed, reducing the possibility of loosening of the first structure 1 and the second structure 2.

[0034] Taking the first structure 1 as a network card and the second structure 2 as a Wifi antenna head as an example, the Wifi antenna head is assembled to the network card, and then the network card is inserted into the slot of the connector 9. During the process, the network card and the Wifi antenna head are locked by the locking mechanism, reducing the possibility of loosening of the Wifi antenna head.

[0035] In some specific embodiments, the locking mechanism comprises a rotating shaft 5, a moving member 6 and an elastic member 7. The rotating shaft 5 is arranged on the fixing member 4.

Optionally, the fixing member 4 is provided with an abutting wall 42. The rotating shaft 5 is fixed on the abutting wall 42. The elastic member 7 is located between the abutting wall 42 and the fixing member 4. The elastic force of the elastic member 7 can make the moving member 6 move away from the abutting wall 42. The moving member 6 is provided with a first cam. The pressing member 3 is provided with a second cam. The first cam and the second cam are matched. The elastic member 7 is elastically compressed, so that the second cam can rotate relative to the first cam. The elastic member 7 can make the first cam and the second cam match to clamp the pressing member 3 and the fixing member 4 after the elastic rebound force, so as to realize the unlocking and locking of the locking mechanism, thereby realizing the opening and pressing action of the pressing member 3 and the fixing member 4.

[0036] In some specific embodiments, the first cam is provided with a first abutting slope and a second abutting slope; the second cam is provided with a third abutting slope; the third abutting slope and the first abutting slope interact to compress the elastic member 7 by the moving member 6, and after the pressing member 3 rotates by a set angle, the third abutting slope and the first abutting slope abut under the elastic restoring force of the elastic member 7. The third abutting slope and the first abutting slope interact to compress the elastic member 7 by the moving member 6, and the elastic member 7 is elastically compressed, so that the second cam can rotate relative to the first cam, the locking mechanism can be unlocked, and thus the pressing member 3 and the fixed member 4 can be opened. The moving member 6 compresses the elastic member 7, and after the pressing member 3 rotates by a set angle, the third abutting slope and the first abutting slope abut under the elastic restoring force of the elastic member 7, which can realize the locking of the locking mechanism, and thus the pressing action of the pressing member 3 and the fixed member 4 can be realized.

[0037] In some specific embodiments, the pressing member 3 is provided with a first limiting portion 31 and a second limiting portion 32 on both sides of the length direction of the rotating shaft 5. When the pressing member 3 is locked with the fixed member 4, the first limiting portion 31 and the second limiting portion 32 can be arranged on the first structural member 1 respectively, so as to limit the stability of the pressing member 3.

[0038] In some specific embodiments, the locking mechanism comprises a rotating shaft 5, a moving member 6 and an elastic member 7; the rotating shaft 5 is arranged on the fixed member 4; the moving member 6 and the elastic member 7 are both sleeved on the rotating shaft 5, and the elastic member 7 is located between the moving member 6 and the fixed member 4; the pressing member 3 is provided with a driving wheel 33, the cross section of the moving member 6 towards the driving wheel 33 is provided with a plurality of grooves 61, the plurality of grooves 61 are sequentially arranged along the circumference of the moving member 6, the end surface of the driving wheel 33 towards the moving member 6 is provided with a plurality of protrusions 331, and the plurality of protrusions 331 are sequentially arranged along the circumference of the driving wheel 33; the protrusion 331 cooperates with the groove 61.

Rotate the pressing member 3, so that the first limiting portion 31 and the second limiting portion 32 on both sides of the pressing member 3 are located on both sides of the first structural member 1 respectively, and the elastic member 7 is extruded by the moving member 6 by the cooperation of the protrusion 331 and the groove 61. When the pressing member 3 is rotated, the moving member 6 extrudes the elastic member 7 to the maximum stroke, and continues to rotate the pressing member 3, so that the driving wheel 33 rotates through a protrusion 331 and is tightly matched with the moving member 6, and continues to circulate this action, so that the pressing member 3 can be rotated by a set angle and fixed in position.

[0040] When disassembling, the pressing member 3 only needs to be rotated in the opposite direction.

[0041] In some specific embodiments, a gap is provided between the fixing member 4 and the pressing member 3 for the second structural member 2 to pass through, which can improve the stability of the connection between the first structural member 1 and the second structural member 2.

[0045] The board card fixing mechanism provided by the embodiment of the present disclosure is installed first to assemble the antenna head and the network card, then the board card fixing mechanism is matched with the network card, and then the fixing member 4 is rotated to clamp the antenna head and the network card, so that the combination of the board card fixing mechanism, the antenna head and the network card is combined into a whole, which is inserted into the slot of the connector 9 as a whole, and then is fixed to the stud of the mainboard 8 through the locking screw. In this process, the pressing member 3 is used to press the antenna head and the network card through the locking mechanism, so that the antenna head is not easy to be loosened in the whole process.

[0046] When the pressing member 3 is rotated, the elastic member 7 is pressed and retracted, the elastic member 7 is compressed and deformed to move the moving member 6 back, when the driving wheel 33 is rotated by one tooth, the elastic member 7 rebounds to press the moving member 6 back, the moving member 6 is tightly matched with the driving wheel 33, and the action of compression-deformation-rebound is repeated, so as to complete the rotation and fixation of the pressing member 3.

[0047] When the network card is replaced, the fixing member 4 can also be not disassembled, only the pressing member 3 needs to be rotated to be opened, after the network card is replaced, the pressing member 3 is rotated to press the network card, and the replacement action is completed.
