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 password mechanical lock. The electronic password mechanical lock aims to achieve the effects that different passwords correspond to different unlocking keys, warning and protection are conducted when the lock is unlocked forcibly, and the safety of the lock is enhanced. An internal lock cylinder is installed on a front plate of a lock shell, a plurality of external lock cylinders are arranged on the internal lock cylinder in a sleeved mode, a plurality of radial holes are evenly formed in the external lock cylinders, pins are installed in the holes in a sliding mode, the lengths of the pins are different, a key hole is formed in the position of each hole, blind holes are formed in a bus on the internal lock cylinder, the number of the blind holes is the same as that of the external lock cylinders, spring pins are installed in the blind holes in a sliding mode, worm gears are arranged on the outer circles of the external lock cylinders and meshed with worms installed on the lock shell, the self-locking function can be achieved, one end of each worm is fixedly provided with a motor, an unlocking bolt is arranged at the right end of the internal lock cylinder in a sleeved mode, an electric magnet is fixedly installed on the side wall of the internal lock cylinder, the left side of the internal lock cylinder is provided with a limiting groove in the peripheral direction, and a limiting block is arranged on the front plate of the lock shell. The electronic password mechanical lock can achieve the effects that the different passwords correspond to the different unlocking keys, warning and protection are conducted when the lock is unlocked forcibly, and the safety of the lock 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 ...
