A sliding link rail 803 is arranged in the middle of the sliding link 8.

[0056] like Fig.10 As shown, the unlocking push rod 9 is Y-shaped and has a pushing portion 901. In the non-working state, the unlocking link upper rod 702 is pushed upward by the pushing portion 901, so that the unlocking link upper rod 702 slides along the sliding link rail 803, driving the roller 6 to roll out of the roller groove 204, and the block 3 rotates to achieve unlocking.

[0057] The padlock of this application, such as Figure 11-12 As shown, in the working state, the lower part of the lifting ring 4 is subjected to load, driving the roller 6 to enter the roller groove 204. At this time, if there is no manual unlocking, no matter what kind of load the hanging lock is subjected to, the hanging lock will always remain locked. Figure 13-14 As shown, if the hanging lock is not in working state, the lower part of the hanging ring 4 is not loaded, and the unlocking push rod 9 is used to push the unlocking connecting rod 7 upward, so that the roller 6 can be brought out of the roller groove 204, thereby unlocking.

[0058] The hanging lock of the present application can provide a hanging locking mechanism when installing the second floor in the air, so as to prevent the hanging lock from falling off due to vibration during the flight of the aircraft. Among them, the hanging lock forms the most basic locking mechanism through the hook 2 and the block 3; the upper part of the lifting ring 4 is connected to the lower part of the block 3, and the lower part of the lifting ring 4 is connected to the steel cable to carry heavy objects; the lower part of the locking push rod 5 is connected to the lower part of the block 3, and the upper part of the locking push rod 5 is connected to the roller 6. In the locked state, the roller 6 is located in the roller groove 204 at the lower part of the hook 2, and a torsion spring is provided at the connection between the lower part of the locking push rod 5 and the lower part of the block 3 to ensure that the roller 6 is always located in the roller groove 204 when the hanging lock is not loaded in the working state; the lower part of the unlocking link 7 is connected to the locking push rod 5 and the roller 6, and the upper part of the unlocking link 7 is placed on the outer side of the sliding link 8; the lower part of the sliding link 8 is connected to the locking push rod 5 and the block 3, and the upper part is connected to the hook 2 through the sliding rod, and the sliding rod can slide in the hook slide groove 205; the unlocking push rod 9 is used when installing and disassembling the hanging lock and does not participate in the working state. The hook lock of the present application can remain locked in the working state and needs to be manually unlocked to release the working state. The hook lock is very convenient to install and disassemble.
