After the expansion card bracket C is assembled on the circuit board P, the operation body part 111 is operated to rotate along a first rotation direction D2. In practice, usually a user presses the operating body portion 111 to rotate the operating body portion 111 along the first rotation direction D2. The push top 112 will also rotate along the first rotation direction D2 accordingly, and the first push surface S1 will push the first receiving surface S3 of the interlocking body part 121, so that the interlocking body part 121 is pushed and moves along a first direction. A continuous stroke movement.

The limit fixing part 122 and the extension limit part 123 will also move along the first linkage stroke accordingly, so that the positioning column 13 changes from the movable area A1 located in the through hole H1 and the extended movable area A3 of the extended hole H4 to located in the through hole H1 The limiting area A2 of the extension hole H4 and the extending limiting area A4 of the extending hole H4 are fixed by the limiting fixing portion 122 .

Therefore, the locking assembly 1 locks the expansion card bracket C on the circuit board P, as shown in FIG. 8 .

In this embodiment, a cross-sectional area of a fixing region of each fixing hole H2 , H3 is greater than a cross-sectional area of a corresponding locking element 15 passing through. Therefore, when the linkage bracket 12 is pushed up by the rotary operation handle 11 , the linkage bracket 12 can move relative to the locking element 15 and the expansion card bracket C without falling off from the expansion card bracket C.

When the user wants to disassemble the expansion card bracket C from the circuit board P, the user operates the rotary operation handle 11 to rotate along the second rotation direction D3, wherein the second rotation direction D3 is opposite to the first rotation direction D2.

When the operation body part 111 rotates along the second rotation direction D3, the push top 112 will also rotate along the second rotation direction D3, and the second push top surface S2 will go to push the second push receiving surface S4 of the linkage body part 121. , so that the interlocking body part 121 is pushed to move along a second interlocking stroke.

The limit fixing part 122 and the extension limit part 123 will also move along the second interlocking stroke, so that the positioning column 13 changes from the limit area A2 in the through hole H1 to the extension limit area A4 in the extension hole H4 back to the position in the through hole H4. The active area A1 of the hole H1 and the extended active area A3 of the extended hole H4 are separated from the limiting and fixing portion 122 . In this embodiment, the abutting portion 131 of the positioning post 13 will also break away from the limiting and fixing portion 122 , as shown in FIG. 5 . Therefore, the user can disassemble the expansion card bracket C from the circuit board P. As shown in FIG.

In addition, in this embodiment, the extension limiting portion 123 has a guiding slope S5 , wherein the guiding slope S5 is adjacent to the extending limiting area A4 of the extending hole H4 . When the expansion card bracket C is assembled on the circuit board P along the assembly direction D1, the positioning column 13 can correspondingly abut against the guiding inclined surface S5, so that the extension limiting portion 123 drives the second receiving top surface S4 of the linkage body portion 121 to abut against it. The second pushing surface S2 is to prevent the first pushing surface S1 of the operating body part 111 of the rotary operating handle 11 from being pressed against the first pushing surface S3 by gravity during the assembly process, and the position is shown in the sixth figure. As a result, the positioning post 13 cannot penetrate to the active area A1 of the through hole H1 and the extended active area A3 of the extended hole H4. In practice, during the assembly process, the user can also hold the operating body part 111 of the rotary operating handle 11, so that the operating body part 111 is located at the position shown in FIG. The active area A1 and the extended active area A3 of the extended hole H4.

To sum up, the locking assembly provided by the present invention utilizes the rotary operating handle, the linkage bracket and the positioning column to detachably lock the expansion card bracket to the circuit board. Compared with the prior art, the present invention The number of components is obviously less, and there are no more complicated components such as knobs, so the price is lower, and only one corresponding positioning post hole needs to be opened on the circuit board. Moreover, compared with the previous technology that uses multiple rotation knobs to lock and release, and is easy to cause damage to the expansion card bracket due to forgetting to loosen the knob during disassembly, the locking assembly of the present invention only needs to use the rotary operation handle along the first One rotation in the first rotation direction or the second rotation direction can achieve the effect of locking and releasing. Compared with the knob, it is easy to forget to release it. The position of the rotary operation handle can clearly inform the user of the current state. Whether it is locked or unlocked.
