Description

Technical Field

[0001] The present application belongs to the technical field of locks, and specifically relates to a lock. Background Art

[0002] A door lock is a mechanical mechanism that prevents unauthorized entry. In some places, it is far from enough to use locks to prevent theft. Some equipment is far away from people and it is difficult to prevent it from being pried. For example, base stations are the most critical infrastructure in mobile communication networks. They can provide wireless coverage and realize wireless signal transmission between wired communication networks and wireless terminals. The base station is equipped with a power distribution cabinet, which is equipped with important equipment such as power modules and backup power control devices. In order to prevent the theft of important equipment in the power distribution cabinet, an anti-theft lock is installed on the power distribution cabinet.

[0003] The applicant has previously developed a Chinese invention patent with application number 202310938389.3, which discloses a lock comprising a mounting shell, a support frame, a locking mechanism, a latch, a locking mechanism and a driving mechanism. A locking hole is provided on the mounting shell. The support frame is arranged in the mounting shell. An insertion hole is provided on the locking mechanism, and when the locking mechanism is inserted into the mounting shell from the locking hole, the insertion hole is located in the mounting shell. The latch is slidably arranged on the support frame, and when it is inserted into the insertion hole, the lock is in a closed state. The locking mechanism is arranged in the mounting shell and is configured to lock the latch inserted into the insertion hole. The driving mechanism is arranged in the mounting shell and is configured to control the locking mechanism to unlock the latch, and the motor of the driving mechanism is controlled to start and stop through an external wireless communication device or the like. The lock solves the problem that the existing anti-theft locks have low safety performance, resulting in large losses to users.

[0004] However, the latch of the lock needs to be moved to one side of the door frame and completely withdrawn from the mounting shell in order to separate the locking mechanism and the mounting shell, thereby realizing the opening action of the lock. When the lock is closed, the latch needs to be inserted into the locking mechanism and the mounting shell from one side of the door frame in order to lock the lock. This type of lock has no problem being used in a double-door box or a single-sided empty space, but when the space on one side of the door frame is limited, for example, when one side of the door frame is a wall, there is no space for the latch to be inserted into the mounting shell, which results in certain restrictions on the application scenarios of the lock.
