Embodiment Construction

[0026] like figure 1 and figure 2 As shown, the double safety lock bolt device includes a housing 1 , a secondary lock 9 , a motor 3 , a first bolt head 2 and a second bolt head 12 . The secondary lock 9 , the motor 3 , the first bolt head 2 and the second bolt 12 heads are all installed in the housing 1 .

[0027] like figure 2 and image 3 As shown, the casing 1 is provided with a first chute 10, and the first bolt head 2 can be slidably arranged in the first sliding groove 10, that is, the first bolt head 2 can slide in and out of the casing 1 in the first sliding groove 10. . When the first bolt head 2 comes out of the casing 1, it can restrict the bolt, so that the bolt locks the door; when the first bolt head 2 is retracted into the casing 1, the restriction on the bolt is released, thus turning the door handle , the deadbolt is no longer locked. In order to toggle the first bolt head 2 to move, such as Figure 4 As shown, a toggle member 4 that is drive-connect...

Abstract

The invention relates to a double safety lock bolt device with reasonable structure and lower cost. This double safety lock device includes a housing, a motor, and a first bolt head, and is characterized in that: a first chute is provided in the housing, the first bolt head is slidably arranged in the first chute, and the housing is provided with The limiting chute perpendicular to the first chute has a restricting piece that can slide in the limiting chute, and the rear end of the limiting piece is provided with a return spring that drives the limiting piece to reset. A toggle piece connected with the motor is provided, and the toggle piece is connected with the first bolt head through a transmission torsion spring. This kind of double safety lock bolt device drives the first bolt head to move through the motor to realize the first lock, and at the same time, the secondary lock realizes the second lock through the second bolt head, and also has the function of emergency unlocking.

Description

technical field [0001] The invention relates to a lock, in particular to an electric lock bolt applied to a safe. Background technique [0002] Generally, safes and safes include a combination lock and a mechanical lock. Only when the combination lock and the mechanical lock are unlocked at the same time, the door can be opened. Generally speaking, mechanical locks are generally not prone to failure due to their mechanical structure, while combination locks have circuit parts, which are prone to problems. In order to prevent the door from being unable to be opened due to the failure of the combination lock, an emergency mechanical lock for emergency opening of the auxiliary combination lock is generally provided. Therefore, a safe or safe needs to be equipped with two mechanical locks and one combination lock in total, and the overall cost is relatively high. SUMMARY OF THE INVENTION [0003] In view of the deficiencies of the prior art, the present invention innovativel...
