The quick fixing device provided by the embodiment of the invention comprises the sleeve 4 and the mandrel 3, wherein the sleeve 4 is fixedly connected with the fixing frame 6, the mandrel 3 can move in a telescopic manner relative to the sleeve 4, and the mandrel 3 is fixedly connected with the fixing hole 71 of the to-be-fixed piece 7, so that the to-be-fixed piece 7 can be fixedly arranged on the fixing frame 6 through the quick fixing device.

It should be noted that the quick fixing device can be used for quick fixing of the tail of the server board card. The fixing piece 7 to be fixed is an expansion card, and the fixing frame 6 is a tail fixing frame of the expansion card.

Further, the mandrel 3 is provided with a protruding portion 31, the sleeve 4 is provided with a containing groove 41 and a limiting groove 42, the containing groove 41 is used for containing the protruding portion 31, when the mandrel 3 stretches out and draws back, the protruding portion 31 can move in the containing groove 41, the limiting groove 42 is used for limiting the protruding portion 31, and therefore after the mandrel 3 stretches out and draws back the sleeve 4 and is inserted into the fixing hole 71 of the to-be-fixed piece 7, the protruding portion 31 on the mandrel 3 can be rotated into the limiting groove 42 and matched with the limiting groove 42 through rotating the mandrel 3, so that the mandrel 3 is in a locking state, and connection of the to-be-fixed piece 7 and the fixing frame 6 can be achieved.

It should be noted that, when the expansion card is installed, the initial state of the mandrel 3 is contracted in the sleeve 4, after the expansion card is inserted into the card slot of the connector, the mandrel 3 is first extended out of the sleeve 4 and is in butt joint with the fixing hole 71 on the expansion card, then the mandrel 3 is rotated, for example, rotated by 90 °, so that the boss 31 on the mandrel 3 is rotated into the limit slot 42 of the sleeve 4 and is matched with the limit slot 42, so that the mandrel 3 is in a locking state, and thus the fixed connection between the to-be-fixed piece 7 and the fixed frame 6 can be realized.

Compared with the traditional mode of locking by using screws, the quick fixing device provided by the embodiment of the invention can realize quick fixing and installation without disassembling the fixing frame 6, is convenient and quick to disassemble, does not need to use extra tools for operation in the assembling and disassembling process, can be directly locked by rotating the mandrel 3 after insertion during installation, is simple to operate, and can ensure the stability and reliability of connection.

In order to facilitate the extension of the driving mandrel 3, the mandrel 3 is movably connected with a trigger part 1, the trigger part 1 can move relative to the mandrel 3, and the mandrel 3 extends out of the sleeve 4 by adjusting the trigger part 1.

Of course, according to practical needs, the triggering part 1 can be provided in a handle structure, and the triggering part 1 can be rotatably connected to the tail part of the mandrel 3.

Specifically, the trigger part 1 is rotatably connected to the mandrel 3 through a pin 2, and the pin 2 is disposed horizontally and perpendicular to the expansion and contraction direction of the mandrel 3.

More specifically, the triggering part 1 comprises a body 11 and two support arms 12 relatively fixedly connected to the body 11, and the two support arms 12 are respectively provided with a pin hole 121 for the pin shaft 2 to pass through; at the same time, the mandrel 3 is provided with a through hole, the axis of which is perpendicular to the axis of the mandrel 3. In this way, the pin shaft 2 can pass through the pin hole 121 of one side support arm 12, the through hole of the mandrel 3 and the pin hole 121 of the other side support arm 12 in sequence, so that the rotation connection is completed, and the trigger part 1 can rotate around the axis of the pin shaft 2.

Of course, the two ends of the pin shaft 2 can be provided with a protruding structure, so that the pin shaft 2 is ensured not to deviate from.

It should be noted that, in order to facilitate rotation, any arm 12 is provided with an arc surface 122, and the arc surface 122 is used to contact with the end surface of the sleeve 4 when the trigger part 1 rotates, so as to facilitate the rotation flexibility of the trigger part 1, and thus facilitate the conversion of the position state of the trigger part 1. Meanwhile, the distance between the pin hole 121 and the side wall of the support arm 12 should be smaller than the distance between the pin hole 121 and the end of the support arm 12, so that the distance between the pin hole 121 and the end of the support arm 12 is larger to increase the stroke of the mandrel 3.

The quick-fixing device further comprises an elastic element 5, the elastic element 5 providing the spindle 3 with an elastic force that can be extended along the sleeve 4. Specifically, the elastic member 5 is a compression (return) spring, the mandrel 3 is provided with an annular protrusion 32 protruding along the circumferential direction, the sleeve 4 is provided with a through hole along the axial direction, the elastic member 5 is arranged in the through hole of the sleeve 4, and two ends of the elastic member 5 respectively prop against between the annular protrusion 32 and the sleeve 4.

The initial state of the mandrel 3 is contracted in the sleeve 4, and at this time, the trigger part 1 is in the vertical position, and the elastic member 5 is in the compressed state. When the expansion card needs to be installed, the trigger part 1 is manually pulled to enable the trigger part 1 to be turned from the vertical position to the horizontal position (in the process, the trigger part 1 can be conveniently turned to the position state due to the arrangement of the cambered surface 122 on the support arm 12), at this time, under the elastic force of the elastic piece 5, the mandrel 3 can automatically extend out of the sleeve 4, and after the trigger part 1 contacts the sleeve 4, the mandrel 3 stops extending out.

In order to optimise the above embodiment, the end of the sleeve 4 is provided with a D-shaped step surface 43, which D-shaped step surface 43 is intended to be in a rivet fit with a D-shaped hole of the holder 6. The limiting groove 42 may be disposed on the D-shaped step surface 43, or may extend to the sleeve body.

Furthermore, to facilitate the interface of the spindle 3 with the fixing hole 71 of the expansion card, the head 33 of the spindle 3 tapers in diameter in a direction away from the boss 31. Thus, the head 33 facilitates insertion of the spindle 3 when the spindle 3 is inserted into the fixing hole 71.

The process of securing the expansion card is specifically described below:

firstly, riveting a D-shaped step surface 43 with a D-shaped hole on a sheet metal part of a fixing frame 6, manually pulling a trigger part 1 after an expansion card is inserted into a connector clamping groove to enable the trigger part 1 to be rotated from a vertical position to a horizontal position, at the moment, under the elastic force of an elastic piece 5, a mandrel 3 can automatically extend out of a sleeve 4, is inserted into a fixing hole 71 of the expansion card, and stops extending after the trigger part 1 is contacted with the sleeve 4; then, through the rotatory dabber 3 of trigger part 1 (can rotate 90 degrees clockwise or anticlockwise), the bellying 31 of dabber 3 cooperates with the spacing groove 42 of sleeve 4 and blocks, and dabber 3 can't atress retract, forms the locking state, reaches the function demand.
