specific Embodiment approach 1

[0013] Embodiment 1: The anti-theft tumbler lock of this embodiment, wherein at least one outer tumbler 6 is provided with a pressure sensor 8, and at least one photoelectric sensor 7 is arranged around any one of the inner outer tumblers 6, and the outside of the lock cylinder is provided with a The processor (not shown) connected to the pressure sensor 8 and the photoelectric sensor 7, the processor is used to judge the Whether there is an illegal unlocking behavior.

[0014] Specifically, the present invention judges whether illegal unlocking occurs through the pressure sensor arranged at the lower part of the outer tumbler and the photoelectric sensor of the inner lock cylinder. The pins include an inner pin and an outer pin in contact with each other, the outer pin refers to a part in contact with the key, and the inner pin is a part in contact with the spring in the magazine groove. The "surrounding" of "any one of the outer pins" can be the position of the outer pins, ...

specific Embodiment approach 2

[0020] Embodiment 2: This embodiment differs from Embodiment 1 in that: the number of photoelectric sensors 7 is 1, and the preset position is the position where the innermost pin of the inner lock cylinder 2 is located.

[0021] The beneficial effect of this embodiment is: the purpose of detecting illegal unlocking can be achieved by using a group of photoelectric sensors, which saves costs, and the setting of the preset position in this way can accurately determine the position where the key has reached the end of the lock cylinder. It should be noted that "the position of the pin at the deepest part of the inner lock cylinder" should ensure that the pin does not block the receiving part of the photoelectric sensor.

[0022] Other steps and parameters are the same as those in Embodiment 1.

specific Embodiment approach 3

[0023] Specific embodiment three: the difference between this embodiment and specific embodiment one or two is: the quantity of pressure sensor 8 is 1, the quantity of photoelectric sensor 7 is 1, and pressure sensor 8 is arranged on the pin 6 of inner lock core 2 deepest. At the bottom, the photoelectric sensor 7 sets the deepest position where the end of the key 9 can be inserted;

[0024] Processors include:

[0025] The first detection unit is used to determine whether the receiving end of the photoelectric sensor detects a light signal within a preset time threshold when the pressure received by the pressure sensor is greater than the gravity of the marble, and if so, the processor sends out a warning message.

[0026] It can be seen from the principle of the normal unlocking process in the specific embodiment 1 that when the pin 6 is lifted during the normal unlocking process, the key 9 should have been fully inserted, so when the pressure sensor 8 detects a pressure cha...

Abstract

The invention relates to the field of antitheft locks, in particular to an antitheft cylinder lock and a graphene antitheft cylinder lock. Through the antitheft cylinder lock and the graphene antitheft cylinder lock, the defects that an existing cylinder lock is liable to error detection, and detection logic is too rough can be overcome. A pressure sensor is arranged on the lower portion of at least one outer cylinder of the antitheft cylinder lock, a photoelectric sensor is arranged in the default position in an inner lock cylinder. A processor is arranged outside the lock cylinder and is connected with the pressure sensor and the photoelectric sensor. The processor is used for judging whether illegal unlocking behavior occurs according to timing characteristics of signals detected by thepressure sensor and the photoelectric sensor and the signal numerical value detected by the pressure sensor. The invention further includes the graphene antitheft cylinder lock. The scheme is suitable for manufacturing antitheft locks.

Description

technical field [0001] The invention relates to the field of anti-theft locks, in particular to an anti-theft tumbler lock and a graphene anti-theft tumbler lock. Background technique [0002] The tumbler lock is the preferred device for residential anti-theft locks and office door locks. It has the advantages of simple use and low cost. In the past, the measure to enhance the safety of the tumbler lock and prevent it from being tried was to increase the complexity of the mechanical lock cylinder. Taking the tumbler lock as an example, it has undergone three generations of updates, namely A-level locks, B-level locks and super B-level locks. Its mechanical structure is becoming more and more complicated. Ordered 100. Although the difficulty of technical trial development is increasing, as the number of parts increases, the reliability will decrease accordingly. [0003] The basic principle of the pin lock is to control the lock by adjusting the relative position of the int...
