Double control lock locking resetting-mechanism and electronic-mechanical double controlled lock

Abstract

The invention discloses a locking reset mechanism for a double control lock, comprising a motor, a worm, a worm wheel, a deflector rod, a pin and a bolt body; wherein, the bolt body can extend out or retract in a lock case; the motor which is fixed with the lock case of the double control lock has the output shaft fixed with the worm; the worm can be engaged with the worm wheel which is rotationally fixed on the lock case; the fixed end of the deflector rod is fixed on the end face of the worm wheel while the free end is slidebly connected with the pin; the rotation of the worm wheel can drive the deflector rod to toggle and drive the pin to slide; the bolt body can slide in the lock case between the extending position and the retracting position; the pin can slide in the lock case between the locking position and the unlocking position; a locking block of the pin on the locking position can be matched with a locking opening to lock the bolt body and prevent the bolt body from slidingto the retracting position; and the bolt body on the retracting position can prevent the pin to slide to the locking position. The locking reset mechanism for a double control lock has high reliability and strong commonality.

Description

technical field [0001] The invention relates to a double-control lock mechanism, which is characterized in that it relates to a double-control lock reset mechanism. In addition, it also relates to an electro-mechanical double control lock comprising the above-mentioned double control lock reset mechanism. Background technique [0002] In order to adapt to various needs, the application of double-control locks or multi-control locks that control a lock with two or more keys is becoming more and more extensive. Among them, in the safe business of banks or other financial institutions, dual-control locks are a commonly used operating equipment. [0003] The double-control lock in the safe business generally includes a lock body, a master key and a guest key. The lock body is provided with a deadbolt body. There are two key interfaces, one for the main key and the other for the guest key. The master key is generally kept in the bank business office. In order to facilitate the...

Problems solved by technology

[0008] Although the above-mentioned prior art can realize the locking of the deadbolt body, it can also realize the reset of the locking block when the deadbolt body stretches out to lock the deadbolt body, but the locking block in the prior art utilizes Gravity achieves locking and reset. Such a structure will affect the realization of the locking function when the magnetic force of the magnet is weakened and subjected to vibration, and the reliability of the function is low.

[0009] In addition, because gravity is used to achieve reset or locking, when the double control lock needs to be installed in different directions, the structural arrangement of the lock reset mechanism needs to be changed, so the versatility of the double control lock lock reset mechanism is greatly affected
