Referring to fig. 5, which is a schematic diagram illustrating the pull-out unlocking mechanism 100 in a locked state, when the locking block 30 is in a substantially horizontal state, the main body 31 is substantially flush with the upper surface of the housing 10, the locking portion 33 protrudes from the upper surface of the housing 10 to lock with the internal structure of the rack, the first shaft 32 is located in the receiving portion 111 on the housing, the second shaft 34 is located in the receiving slot 224 on the tab 20, and the second shaft 34 is located on a side of the receiving slot 224 adjacent to the lower surface of the housing 10, the return spring is in a natural state.
Referring to fig. 6, the pull-type unlocking mechanism 100 is schematically shown in an unlocked state, in which the lock block 30 is in an inclined state with respect to the lower surface of the housing, the main body portion 31 is arranged inclined with respect to the upper surface of the housing 10, the locking portion 33 is substantially flush with the upper surface of the housing 10 so as to be separated from the internal structure of the rack, the first shaft 32 is located in the receiving portion 111 of the housing, the second shaft 34 is located in the receiving groove 224 of the tab 20, and the second shaft 34 is located on a side of the receiving groove 224 close to the housing 10, so that the return spring is in a compressed state.
The unlocking process of the pull-type unlocking mechanism 100 is changed from fig. 5 to fig. 6, in the unlocking process, the pull ring 20 is pulled along the pulling direction, the pull ring 20 moves rightwards along the pulling direction, at this time, the second shaft 34 and the receiving groove 224 move relatively, the second shaft 34 moves gradually in the receiving groove 224 from the side close to the lower surface of the housing 10 to the side far away from the lower surface of the housing 10, and since the receiving groove 224 is arranged obliquely, when the second shaft 34 moves relatively in the receiving groove 224, the horizontal height of the second shaft 34 changes gradually. The lock block 30 can only rotate in the receiving portion 111 around the first shaft 32, so that the second shaft 34 of the second body 312 can only move circularly upwards around the first shaft 32. Meanwhile, the latching part 33 on the first main body part 311 moves downwards circularly around the first shaft body 32, the horizontal height of the latching part 33 gradually decreases until the latching part is approximately flush with the upper surface of the shell 10, and the latching part 33 and the structure inside the frame are separated from each other to achieve unlocking.

The locking process of the pull-type unlocking mechanism 100 is changed from fig. 6 to fig. 5, and the locking process and the unlocking process are reversible processes. Since the return spring is in an extended state after unlocking and has a certain elastic force, when the tab 20 is released, the tab 20 is driven by the elastic force to move leftward in a direction opposite to the pulling direction, and at this time, the second shaft 34 and the receiving groove 224 will move relatively, and the second shaft 34 moves gradually in the receiving groove 224 from a side away from the lower surface of the housing 10 to a side adjacent to the lower surface of the housing 10, because the receiving groove 224 is disposed obliquely, when the second shaft 34 moves relatively in the receiving groove 224, the horizontal height of the second shaft 34 changes gradually. The lock block 30 can only rotate around the first shaft 32 in the receiving portion 111, and therefore, the second shaft 34 of the second body portion 312 can only move downward and circularly around the first shaft 32. Meanwhile, the buckling part 33 on the first main body part 311 moves upwards in a circle around the first shaft body 32, the horizontal height of the buckling part 33 gradually rises until the buckling part is completely protruded out of the surface of the shell 10, and the buckling part 33 is matched with the structure in the inner part of the machine frame to realize locking.
