The quick fixing device provided by the embodiment of the invention comprises a sleeve 4 and a mandrel 3, wherein the sleeve 4 is fixedly connected with a fixing frame 6, the mandrel 3 can move in a telescopic way relative to the sleeve 4, and the mandrel 3 is fixedly connected with a fixing hole 71 of a 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 quickly fixing the tail of the server board card. The fixing member 7 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 the protruding portion 31, the sleeve 4 is provided with an accommodating groove 41 and a limiting groove 42, the accommodating groove 41 is used for accommodating the protruding portion 31, when the mandrel 3 performs telescopic motion, the protruding portion 31 can move in the accommodating groove 41, and the limiting groove 42 is used for limiting the protruding portion 31, so that after the mandrel 3 stretches out of the sleeve 4 and is inserted into the fixing hole 71 of the fixing piece 7, through rotating the mandrel 3, the protruding portion 31 on the mandrel 3 can rotate to the limiting groove 42 and is matched with the limiting groove 42, so that the mandrel 3 is in a locking state, and therefore the fixing piece 7 and the fixing frame 6 can be connected.

It should be noted that the initial state of the mandrel 3 is contracted in the sleeve 4, when the expansion card is installed, after the expansion card is inserted into the slot of the connector, firstly, the mandrel 3 is extended out of the sleeve 4 and butted with the fixing hole 71 on the expansion card, and then, the mandrel 3 is rotated, for example, by 90 degrees, so that the protruding portion 31 on the mandrel 3 is rotated into the limiting groove 42 of the sleeve 4 and matched with the limiting groove 42, so that the mandrel 3 is in a locking state, and thus, the fixing connection between the fixing member 7 and the fixing frame 6 can be realized.

Compared with the traditional mode of locking by using screws, the rapid fixing device provided by the embodiment of the invention can realize rapid fixed installation without disassembling the fixing frame 6, is convenient and rapid to disassemble, is operated without using an additional tool in the assembling and disassembling process, can be directly inserted by the mandrel 3 and then rotationally locked in the installation process, is simple to operate, and can ensure the stability and reliability of connection.

In order to drive the mandrel 3 to extend, 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, the triggering part 1 can be configured as a handle structure according to actual requirements, 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 arranged along a horizontal direction perpendicular to the stretching direction of the mandrel 3.

More specifically, the triggering part 1 includes a body 11 and two support arms 12 fixed 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; meanwhile, the mandrel 3 is provided with a through hole, and the axis of the through hole is perpendicular to the axis of the mandrel 3. In this way, the pin 2 can be inserted through the pin hole 121 of the one side arm 12, the through hole of the core shaft 3 and the pin hole 121 of the other side arm 12 in sequence, so that the rotation connection is completed and the trigger 1 can rotate around the axis of the pin 2.

Of course, the two ends of the pin shaft 2 can be provided with protruding structures, so that the pin shaft 2 is ensured not to be separated.

It should be noted that, in order to facilitate the rotation, any one of the arms 12 is provided with a cambered surface 122, and the cambered surface 122 is used for contacting with the end surface of the sleeve 4 when the trigger part 1 rotates, which is beneficial to improving the flexibility of the rotation of the trigger part 1, thereby facilitating the position conversion 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 stroke of the mandrel 3 can be increased by using the arrangement mode that the distance between the pin hole 121 and the end of the support arm 12 is larger.

Furthermore, the quick-fastening means comprise an elastic element 5, which elastic element 5 provides the mandrel 3 with an elastic force that can extend along the sleeve 4. Specifically, this elastic component 5 specifically is compression (reset) spring, and dabber 3 is equipped with along bellied annular arch 32 of circumference, and sleeve 4 is equipped with along axial through-hole, and elastic component 5 locates in the through-hole of sleeve 4, and the both ends of elastic component 5 support respectively between annular arch 32 and sleeve 4.

It should be noted that the initial state of the mandrel 3 is contracted in the sleeve 4, and at this time, the trigger 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 pulled manually, so that the trigger part 1 rotates from a vertical position to a horizontal position (in the process, the trigger part 1 can conveniently switch the position state due to the arrangement of the arc surface 122 on the support arm 12), at the moment, under the elastic action 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 optimize the above embodiment, the end of the sleeve 4 is provided with a D-shaped step surface 43, and the D-shaped step surface 43 is used for riveting fit with a D-shaped hole of the fixing frame 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 abutment of the mandrel 3 with the fixing hole 71 of the expansion card, the head 33 of the mandrel 3 is tapered in diameter in a direction away from the boss 31. Thus, the head 33 facilitates insertion of the mandrel 3 when the mandrel 3 is inserted into the fixing hole 71.

The process of fixing the expansion card is specifically described as follows:

firstly, the D-shaped step surface 43 is riveted with a D-shaped hole in a sheet metal part of the fixing frame 6, after the expansion card is inserted into a connector clamping groove, the trigger part 1 is manually pulled to enable the trigger part 1 to rotate from a vertical position to a horizontal position, at the moment, under the action of the elastic force of the elastic part 5, the mandrel 3 can automatically extend out of the sleeve 4, is oppositely inserted into the fixing hole 71 of the expansion card, and stops extending after the trigger part 1 contacts the sleeve 4; then, the mandrel 3 is rotated by the trigger part 1 (the mandrel can be rotated by 90 degrees clockwise or anticlockwise), the boss 31 of the mandrel 3 is matched with the limiting groove 42 of the sleeve 4 to be clamped, the mandrel 3 cannot be stressed to retract, a locking state is formed, and the functional requirement is met.

The invention provides a server, comprising the quick fixing device described in the above embodiment; other parts of the server may be referred to in the art and will not be expanded upon herein.

It is noted that, in this specification, relational terms such as first and second, and the like are used solely to distinguish one entity from another entity without necessarily requiring or implying any actual such relationship or order between such entities.

The server and the quick fixing device thereof provided by the invention are described in detail above. The principles and embodiments of the present invention are explained herein using specific examples, which are provided only to help understand the concepts of the present invention and the core concepts thereof.
