DETAILED DESCRIPTION

[0018] like Figure 1-Figure 4 As shown, the outdoor large lock proposed in this embodiment includes a lock body and a waterproof component.

[0019] The lock body includes a handle 4 and a lock core 6 disposed on the handle 4 . The lock frame 1 has a limit lock portion 101 adapted to the lock core 6 . The user inserts a key into the lock core 6 and rotates it to unlock the lock.

[0020] The waterproof component includes a waterproof cover 7 rotatably arranged on the handle 4 and a rubber pad 10 arranged on the waterproof cover 7 and capable of covering the lock core 6 and being moved away from the lock core 6. It also includes a bolt 8 detachably connected to the waterproof cover 7 and a spring 9 connected between the bolt 8 and the lock body. The bolt 8 has a circular ring portion for the spring 9 to press against. The waterproof cover 7 has a rotating cylindrical portion, which is in sliding contact with the handle 4. The rubber pad 10 is sealed at the lock core 6 in the default state to achieve waterproofing of the lock core 6. When unlocking, the waterproof cover 7 is turned away, and the rubber pad 10 is moved away with the waterproof cover 7, so that the user can unlock smoothly. When turning the waterproof cover 7 away, it can be turned away directly, or the waterproof cover 7 can be pulled outward first and then turned away. At this time, the spring 9 is compressed, and the waterproof cover 7 can slide and rotate.

[0021] The lock body includes a lock frame 1, a mounting plate 2 arranged at the rear end of the lock frame 1, a guide frame 3 arranged on the lock frame 1, a rotating frame 11 arranged on the handle 4 and rotatably connected to the lock frame 1, a connecting frame 5 connected between the handle 4 and the rotating frame 11, and two sets of relatively distributed linkage components, the linkage component includes a slider 13 slidably arranged on the guide frame 3 and a connecting plate 12 rotatably connected to the rotating frame 11 and the slider 13 at both ends, and the two sliders 13 move toward or away from each other. After unlocking, the handle 4 is pulled outward, the handle 4 drives the rotating frame 11 to rotate, the rotating frame 11 drives the two connecting plates 12 to move, the two connecting plates 12 drive the two sliders 13 to move toward each other, and the slider 13 drives the external lock rod to move toward each other to achieve unlocking.

[0022] The lock frame 1 has a lock hole a102, the handle 4 has a lock hole b401, the lock hole a102 and the lock hole b401 are provided with a padlock 14, the padlock 14 and the lock core 6 can realize double locking, when unlocking, both the padlock 14 and the lock core 6 need to be opened to unlock.
