Embodiment approach

[0039] The back side of the handle 20 is provided with a housing 21, and the housing 21 is also provided with an opening 211 for the mechanical locking hook 612 to protrude, so that when the mechanical lock is unlocked, the entire mechanical locking hook 612 can only be locked within the area of ​​the opening 211. Turn inside. As a preferred implementation manner, the mechanical lock cylinder 60 can drive the mechanical lock hook 612 to rotate 40 degrees in the opening 211 .

[0040] Such as Figure 4 and Figure 19 As shown, the electromagnetic assembly 70 also includes an anti-key lock pin 73 for preventing the lock cylinder dial 61 from being separated from the lock pin 72 when the mechanical lock cylinder 60 drives the lock cylinder dial 61 to rotate, and is used to control the anti-key lock. Anti-key electromagnet 74 of pin, fixed seat 13 is provided with the second hole for anti-key lock pin 73 to insert, after whole cabinet locks power-on work, under normal communicat...

Abstract

The invention provides an equipment cabinet lock for preventing vibration retraction. The equipment cabinet lock comprises a base, a handle, an identity verification module, a transmission body, a steel bolt, a mechanical lock cylinder and an electromagnetic assembly. The electromagnetic assembly comprises a locking electromagnet and a locking lock pin driven by the locking electromagnet and usedfor cooperating with a lock cylinder stirring support. The locking lock pin is sleeved with a reset spring, a convex block is arranged on the locking lock pin, and a check elastic sheet for being clamped on the front side or the rear side of the convex block is further arranged in the base and is located below the lock cylinder stirring support. Compared with the prior art, when the equipment cabinet lock is locked, the check elastic sheet is clamped on the front side of the convex block on the locking lock pin, and the locking lock pin is prevented from automatically retracting when bearing vibration. When unlocking is needed, the handle is pressed, the lock cylinder stirring support on the handle presses the check elastic sheet, the check elastic sheet is separated from the locking lockpin, the locking lock pin retracts under the action of the locking electromagnet, and thus normal work of the whole equipment cabinet lock is not influenced, and security is guaranteed.

Description

technical field [0001] The invention relates to a cabinet door lock, in particular to a cabinet lock preventing vibration retraction. Background technique [0002] The existing cabinet lock method is a combination of mechanical unlocking and electric control unlocking. The electronic control unlocking is the main method. The electromagnet controls the pull-in and ejection of the lock pin through power-on and power-off. When the pin is engaged, it is unlocked, and then the handle is rotated 90 degrees from the base, and the transmission body drives the rigid bolt and the heaven and earth rod to move and unlock; mechanical unlocking is supplemented, and when there is no power, the key is used to unlock. Rotate the handle 90 degrees from the base, and drive the steel bolt and the heaven and earth rod to move and unlock through the transmission body. However, when the existing cabinet locks are violently vibrated or bumped, the lock pins are subjected to a huge impact force, an...
