Photoelectric digital spring lock core

Abstract

The invention discloses a photoelectric digital spring lock core which comprises a spring lock core and a photoelectric control circuit, wherein the spring lock core comprises a lock hole, an inner core capable of rotating with an inserted matched key, a marble hole internally provided with a spring and a marble, and an unlocking transmission part; the photoelectric control circuit comprises an unlocking coding signal detection circuit and an unlocking signal drive circuit; and the lock core comprises a photoelectric coding member and an unlocking switch and a power switch. In the photoelectric digital spring lock core, a photoelectric technology is applied to the traditional spring lock core, optical channel coding combinations are enough so as not to be easy to crack; the lock core and the lock body can be separately installed, therefore, the destructiveness preventing effect is good; the photoelectric digital spring lock core and the original mechanical spring lock form double insurance, which lowers the mutual opening rate, and has higher safety and stronger destructiveness preventing effect; and when the key is inserted, a circuit is switched on for electrifying, therefore, electricity and energy are saved. In addition, the invention has the advantages of simple structure, high reliability, low cost, easy reconstruction and production as well as manufacture, convenient popularization and installation as well as maintenance.

Description

technical field [0001] The invention relates to a tumbler lock cylinder, more specifically, to a photoelectric digital pin lock cylinder. Background technique [0002] Locks can generally be divided into two categories: mechanical locks and electronic locks: [0003] The conventional traditional fully mechanical pin lock is generally composed of a lock body, a lock cylinder and a key. The principle is: the key is inserted into the lock cylinder, such as the position of each key tooth matches the pin hole in the lock cylinder, and the height of each key tooth is just right. Push the pins in each pin hole to the same set horizontal position, then you can rotate the inner core of the lock cylinder, thereby driving the unlocking transmission part on it, converting the rotation of the inner core into the movement of the bolt on the lock body, and turning the lock Open. This type of lock is easy to be damaged and opened due to its simple structure, and it is also easy to open wi...
