Problems solved by technology

[0003] The "electronic door lock" disclosed in Chinese patent 93232809.1 can be equipped with different types of remote keys, and the computer can identify the identity of the key holder, but this is a pure circuit design, and the operation of its program is easily disturbed and unstable. There is also the danger of outsiders taking direct control of its actuators
The password identification part of the "electronic mechanical lock" disclosed in Chinese patent 89220486.9 is also completed by a pure circuit, and then the key can be inserted to unlock the lock. If the key is lost, the second unlocking barrier will be lost and it will be easily opened.

Embodiment 1

[0023] exist Figure 1 to Figure 5 Among them, the device includes a motor 1, a lock case 2, a spring pin 3, a pin post 4, an inner lock core 5, an outer lock core 6, a worm screw 7, a handle 8, an unlock bolt 9, an electromagnet 10, an unlock bolt reset spring 11 and Inner lock core return spring 12; the left end of the inner lock core 5 is located in the hole of the front plate of the lock housing 2, and is fixedly installed with the handle 8 on the outside of the lock housing 2, and the inner lock core 5 is covered with six side by side Outer lock core 6, and both can be rotated relatively; On the circumferential direction of described outer lock core 6, ten holes along the radial direction are evenly distributed, and one end of the hole pointing to the center of the circle is a through hole, and the other end is a blind hole, and the hole The right side of the outer lock core 6 is provided with chamfers, and each radial hole position on the outer lock core 6 is provided wi...

Embodiment 2

[0026] exist Image 6 In the second embodiment shown, the device can also include a torque sensor 14, and the handle 8 is fixedly installed on the left end of the inner lock cylinder 5 through the torque sensor 14, and the cross-section of the input shaft of the torque sensor 14 is square Inserted into the corresponding hole of the handle 8, the housing of the torque sensor 14 is fixedly connected to the left end of the inner lock cylinder 5 by bolts. The torque sensor 14 can detect the rotating torque of the handle 8. When someone tries to increase the torque on the handle 8 for destructive unlocking, the controller detects that the large torque signal from the torque sensor 14 will give an alarm, and at the same time ensure that the electromagnet 10 power off, the lock will not be opened.

Embodiment 3

[0028] exist Figure 7 In the third embodiment shown, the device can also include a proximity switch 13, and the axis of the radial hole on the right side of the inner lock core 5 and the axis of the iron core of the electromagnet 10 are staggered by a certain angle during installation. The proximity switch 13 is fixedly installed in the left side through hole of the unlocking bolt 9 by bolts, and is positioned on the axis of the radial hole on the right side of the inner lock core 5 . When the inner lock core 5 rotated, the right radial hole on it turned away from the proximity switch 13, and the proximity switch 13 would have a signal output to detect whether the inserted key was correct. When the password and the key were all correct, the electromagnet 10 can be powered on to complete the follow-up unlocking.

[0029] In summary, the internal lock cylinder can be adjusted and combined through the input password, that is, after changing the password, the designated key must...

Abstract

The invention discloses an electronic cipher mechanical lock, which aims to realize that different ciphers correspond to different unlocking keys, alarm and protect when the lock is forcibly unlocked, and enhance the safety of the lock. The inner lock core is installed on the front plate of the lock housing, and a plurality of outer lock cores are sheathed on it. A plurality of radial holes are evenly distributed on the outer lock cores. The pins are slidably installed in the holes and have different lengths. A keyhole is provided at the position of each hole, and a busbar on the inner lock cylinder is provided with the same number of blind holes as the number of the outer lock cylinder. Mesh with the worm installed on the lock case, and can form self-locking, the motor is fixed at one end of the worm, the unlocking bolt is set on the right end of the inner lock cylinder, and the electromagnet is fixedly installed on the side wall, and the left side of the inner lock cylinder is along the circumferential direction Open the limit groove, and set the limit block on the front plate of the lock housing. The present invention can realize that different passwords correspond to different unlocking keys, alarm and protection are performed when the lock is forcibly unlocked, and the safety of the lockset is enhanced.

Description

technical field [0001] The invention relates to a safety lock, in particular to an electronic password mechanical lock. Background technique [0002] Locks are an indispensable tool in people's daily life. In order to prevent theft and protect personal and property safety, various locks have been manufactured one after another. However, with the continuous development of unlocking technology, the defects of many locks are constantly exposed. The tumbler mechanical lock used on various doors can be unlocked with a master key, which is not resistant to smashing or drilling, and is easily damaged. The one-way combination lock installed on the safe also has the possibility of being opened by the normal unlocking rules and feelings. [0003] The "electronic door lock" disclosed in Chinese patent 93232809.1 can be equipped with different types of remote keys, and the computer can identify the identity of the key holder, but this is a pure circuit design, and the operation of its ...
