Padlock with travel switch

Abstract

The invention provides a padlock with a travel switch. The padlock comprises a lock shell, a lock rod and a lock cylinder, wherein the lock cylinder is fixedly connected in the lock shell, the lock rod penetrates through the lock shell and is in sliding connection with the lock cylinder, the bottom of one end of the lock rod is fixedly connected with a limiting rod, the bottom of the limiting rodis fixedly connected with a contact block, one side of the contact block is fixedly connected with a first travel switch, and when the padlock is closed, the contact block abuts against the first travel switch; a slide way is formed in the lock cylinder, a lock block is arranged in the slide way, the lock block is connected to an output end of a motor, so that the motor drives the lock block to move in the slide way, one end of the lock block is inserted into the lock rod, a second travel switch is arranged in the slide way at the other end of the lock block, the second travel switch comprisesa front contact and a rear contact, when the lock block is inserted into the lock rod, the front contact is abutted against the lock block, and when the lock block moves out of the lock rod, the rearcontact is abutted against the lock block; a circuit board, the motor, the first travel switch and the second travel switch are further fixedly connected in the lock cylinder and are electrically connected with the circuit board. The padlock with the travel switch has the advantages of being capable of recording the opening and closing of the padlock and giving an alarm when the lock is not locked.

Description

technical field [0001] The invention relates to the field of locks, in particular to a padlock with a travel switch. Background technique [0002] Today's padlocks are all purely mechanical structures. By inserting the lock rod into the lock case and inserting the lock block into the lock rod at the same time, the lock rod cannot automatically pop out of the lock case to achieve the purpose of locking; but the pure mechanical lock When locking, although the lock rod is inserted into the lock case, but the insertion depth of the lock rod is not enough, the lock block will not be inserted into the lock rod, and the lock rod will not pop out of the lock case temporarily under the friction of the hole wall. Because the user cannot observe the situation in the lock case, there is a greater probability that the user thinks it is locked. Once the user leaves, it is easy for lawbreakers to take advantage of the situation and reduce the safety performance of the padlock. Contents o...

[0002] Today's padlocks are all purely mechanical structures. By inserting the lock rod into the lock case and inserting the lock block into the lock rod at the same time, the lock rod cannot automatically pop out of the lock case to achieve the purpose of locking; but the pure mechanical lock When locking, although the lock rod is inserted into the lock case, but the insertion depth of the lock rod is not enough, the lock block will not be inserted into the lock rod, and the lock rod will not pop out of the lock case temporarily under the friction of the hole wall. Because the user cannot observe the situation inside the lock case, there is a high probability that the user thinks it is locked. Once the user leaves, it is easy for criminals to take advantage of it and reduce the safety performance of the padlock.
