Please refer to Figure 6. During this process, since the bottom wall of the first groove section 4221 has a supporting force that gradually changes in one direction towards the connecting shaft 41, this supporting force will follow the shape of the locking section 313 to a certain extent. The shaft 41 is gradually pulled out of the locking section 313, that is, it is directly separated from the locking section 313 along the shape of the locking section 313, until the connecting shaft 41 moves to the connection between the first groove section 4221 and the second groove section 4222. 41 is disengaged from the locking section 313, thereby releasing the restriction of the connecting shaft 41 by the locking section 313. By directly pulling the connecting shaft 41 out of the locking section 313 through the first groove section 4221, the restriction of the connecting shaft 41 by the locking section 313 can be quickly released.

In one embodiment, the first groove section 4221 is a linear groove section. Compared with arc-shaped or other shapes, the side of the first groove section 4221 of the linear groove section has less obstruction to the connecting shaft 41, so as to reduce the resistance of the connecting shaft 41 from the first groove section 4221 during movement, thereby saving operations.

The second groove section 4222 is connected to the first groove section 4221, and the second groove section 4222 and the first groove section 4221 form an included angle. The first groove section 4221 is used to release the restriction of the connecting shaft 41 by the locking section 313, and the second groove section 4222 is used to reduce the obstruction of the swinging part 422 to the movement of the connecting shaft 41 in the sliding section 312, so as to improve the sliding movement of the connecting shaft 41. The smoothness of movement of the moving segment 312.

In one embodiment, the second groove section 4222 is a linear groove section. Please refer to Figure 7. When the connecting shaft 41 moves on the sliding section 312, the second groove section 4222 gradually becomes parallel or tangent to the sliding section 312, reducing the friction between the side walls of the second groove section 4222 and the connecting shaft 41 during the sliding movement. The movement of the segment 312 is hindered to improve the smoothness of the connecting shaft 41 moving in the sliding segment 312.

Please refer to FIG. 3 , when the connecting shaft 41 is in the limiting section 311 , the second groove section 4222 is parallel to and aligned with the limiting section 311 . At this time, the blocking member 20 restricts the rotation of the first link 42. If the driving member 30 moves, the connecting shaft 41 will move in the limiting section 311. However, since the limiting section 311 is a linear groove section, the connecting shaft 41 will move in the limiting section 311. The movement within the limiting section 311 will not cause the first link 42 to rotate, thereby preventing the first link 42 from escaping from the restriction of the blocking member 20 .

Please refer to FIGS. 2 and 5 , the connecting rod structure 40 also includes a second connecting rod 43 and a tensile member 44 . The second link 43 and the tensile member 44 are respectively provided on the second mounting part 12, and the second link 43 is connected to the first link 42 and the tensile member 44 respectively. The tensile member 44 is used to tighten the second link 43. 43 generates a moment, so that the second link 43 restricts the connecting shaft 41 in the locking section 313 to prevent the connecting shaft 41 from disengaging from the locking section 313 due to shaking or vibration of the connecting mechanism 100 .

In one embodiment, the second link 43 includes a connecting part 431 , a rotating part 432 and a free part 433 . The rotating part 432 is connected to the connecting part 431 and the free part 433 respectively. The connecting part 431 is movably connected to the connecting shaft 41 . The rotating part 432 is rotatably provided on the mounting part 10 . The free part 433 is connected to one end of the tensile member 44 . The tensile member 44 The other end is connected to the second mounting part 12. When the connecting shaft 41 is located at the locking section 313, the tensile member 44 pulls the free part 433 upward. Since the rotating part 432 is rotatably provided on the mounting part 10, the rotating part 432 has a tendency to rotate counterclockwise, and the connecting part 431 has a tendency to rotate counterclockwise. The downward movement trend, that is, the tendency to move deeper into the locking section 313 , keeps the connecting shaft 41 in contact with the deepest part of the locking section 313 , thereby limiting the connecting shaft 41 within the locking section 313 .

When the second component 300 is detached from the first component 200, the specific process is as follows: Referring to Figure 3, pull the driving member 30 outward from the mounting member 10, that is, the driving member 30 moves forward relative to the mounting member 10. The limiting groove 32 and the limiting portion 13 are unlocked. At this time, the connecting shaft 41 located in the limiting section 311 is stationary relative to the mounting member 10 , but the limiting section 311 moves forward relative to the connecting shaft 41 .

Please refer to Figure 4 and Figure 7, continue to pull out the driving member 30, the sliding section 312 begins to contact the connecting shaft 41, because the sliding section 312 is tilted, the connecting shaft 41 starts to move under the action of the sliding section 312, The first link 42 starts to rotate clockwise, the second bump 4b starts to break away from the limiting hole 21 of the blocking member 20, and the second link 43 starts to rotate counterclockwise.

Please refer to Figure 5, and continue to pull out the driving member 30. After the bottom end of the locking section 313 contacts the connecting shaft 41, the connecting shaft 41 is restricted in the locking section 313, so that the driving member 30 cannot be pulled out anymore. Cannot be pushed into mounting 10. The second protrusion 4b is completely separated from the limiting hole 21, that is, the restriction of the mounting member 10 by the blocking member 20 is released, and the second assembly 300 can be disassembled from the first assembly 200.

It should be noted that after the bottom end of the locking section 313 contacts the connecting shaft 41, if the driving member 30 is continued to be pulled out or pushed into the mounting member 10, since the side of the locking section 313 is an arc surface, The side surface of the locking section 313 drives the second link 43 to rotate (clockwise and counterclockwise) through the connecting shaft 41 . However, since the driving member 30 cannot move up and down, the second connecting rod 43 cannot actually rotate, and the connecting shaft 41 cannot move, resulting in the driving member 30 being unable to move forward and backward.

When the second component 300 is locked to the first component 200, the specific process is as follows: Please refer to FIG. 5, place the first component 200 on the second component 300, and push the first component 200 in through the driving member 30. In the second assembly 300, when the first protrusion 4a contacts the blocking member 20, the first connecting rod 42 begins to rotate counterclockwise, and the connecting shaft 41 begins to break away from the locking segment 313 under the action of the first groove segment 4221, and the driving member 30 begins to be pushed into the mounting 10. Please refer to Figures 6 and 7. When the second protrusion 4b enters the limiting hole 21, the connecting shaft 41 is completely separated from the locking section 313, so that the connecting shaft 41 enters the second groove section 4222 and the sliding section 312 in sequence.

Please refer to Figures 2 and 7, continue to push the driving member 30, the second groove section 4222 and the sliding section 312 respectively move backward relative to the connecting shaft 41, until the front end of the second groove section 4222 and the limiting section 311 contact the connecting shaft 41 , the second bump 4b completely enters the limiting hole 21, and the driving member 30 is limited in the mounting member 10 through the cooperation of the limiting portion 13 and the limiting groove 32. At this time, the installation of the first component 200 and the second component 300 is completed.

When the hard disk module 400 is disassembled from the chassis 300a, the memory module 200a is in an unlocked state, and the memory module 200a is separated from the hard disk module 400.
