The electronic padlock further comprises a soft plug 26, and the soft plug 26 is plugged in the jack 105 to play a role in preventing water and dust, so that water and dust are effectively prevented from entering the lock shell 101.

Further, a first limiting groove 205 and a second limiting groove 206 are formed in the long hooking section 202 below the second locking groove 204, wherein the first limiting groove 205 is axially formed in one side of the outer peripheral surface of the lower end of the long hooking section 202 and is in a groove cutting structure along an axial cross section, the second limiting groove 206 is formed in a circular groove in the outer periphery of the tail end of the long hooking section 202, and the second limiting groove 206 is connected to the lower end of the first limiting groove 205. The lock hook 2 can limit longitudinal movement and rotation in the lock body 1 by providing the first limiting groove 205 and the second limiting groove 206. A limiting pin 3 is fixedly arranged in the lock case 101 corresponding to the lock hook assembly cavity, the limiting pin 3 is vertically arranged in the first limiting groove 205 of the long hook section 202, and is used for preventing the long hook section 202 from being separated from the lock case 101 after sliding up when the first limiting groove 205 axially slides, and limiting the sliding of the long hook section 202.

Furthermore, in order to prevent the lock from being pulled by external force, the corresponding locking body is easy to disengage from the locking groove, so the depth of the groove is slightly deeper when designing the locking groove of the short hook section. The long hook section is movably arranged in the lock body in a limiting way, so that the groove depth of the locking groove of the long hook section is slightly shallow for preventing the long hook section from being easily broken. And because the two locking bodies have the same size, the two swinging blocks have the same size, and the locking grooves of the short hooking section and the locking grooves of the long hooking section have different groove depths, when the two locking bodies need to be simultaneously abutted in the corresponding two locking grooves, the angles of the two locking bodies when abutting against the two swinging blocks are different, so that one end of the lock pin abutting against the two locking bodies is set to be a step surface, the high surface is relatively acted on the locking grooves of the short hooking section, and the low surface is relatively acted on the locking grooves of the long hooking section.

To sum up, the utility model discloses electronic padlock is through setting up mechanical unlocking subassembly, under the circumstances that drive element 13 has the damage, usable mechanical unlocking subassembly carries out urgent unblock, need the phenomenon that violence unblanked when avoiding appearing drive element 13 damage. In addition, because be provided with shockproof round pin in the tool to lock, even this scheme tool to lock suffers from strong rocking, inertia unblanking can not appear yet, and stability is good. Compared with the prior comparison documents, the technical problem of preventing the inertia unlocking skill can be solved, in the scheme, the technical problem of vibration inertia unlocking can be further solved by only using one shockproof pin and one electronic unlocking mechanism, in addition, two driving elements are required in the comparison documents, the cost is higher than that of the shockproof pin, correspondingly, the energy required for opening the lock of the scheme is low, and the related electronic circuit is relatively simple, so that the electronic circuit in the lock becomes simple; above synthesizing, this scheme tool to lock simple structure, the stable performance is reliable, low in production cost.
