Lock pin

Abstract

This invention discloses a lock pin structure, which comprises the first movable part (1), the second movable part (2), shell (3), clutch mechanism and resetting-mechanism (4); wherein the first movable part and the second movable part are set inside the shell, and by the clutch mechanism, it produces the locking or hands-off relationship between the first movable part, the second movable part and the shell; the resetting-mechanism makes the first movable part and the second movable part restoring to the initial condition. Said structure is convenient to back-up, and can form several independent back-up component without increasing voltage; besides, the invention can be used directly in the car door and safety deposit box, compatible with kinds of electrical controlling system.

Description

【Technical field】: [0001] The invention relates to a lock cylinder structure. 【Background technique】: [0002] Electronic lock is a new type of lock that is more and more widely used, and it is an updated product of traditional mechanical lock. [0003] The electronic locks currently on the market, whether they work with AC or DC, generally have a working power consumption of several watts (W) to tens of watts (that is, the working voltage is mostly 12-24V, and the working current is 0.2-2A). Due to low efficiency and high power consumption, this type of electronic lock requires a large capacity of the power supply system, so it cannot match the microelectronic control circuit with continuously reduced volume, weight, and power consumption, which also leads to very strict or frequent power consumption requirements in some applications. It is almost impossible to apply in the occasion of power failure, which restricts the popularization and replacement of electronic control ...

[0003] The electronic locks currently on the market, whether they work with AC or DC, generally have a working power consumption of several watts (W) to tens of watts (that is, the working voltage is mostly 12-24V, and the working current is 0.2-2A). Due to low efficiency and high power consumption, this type of electronic lock requires a large capacity of the power supply system, so it cannot match the microelectronic control circuit with continuously reduced volume, weight, and power consumption, which also leads to very strict or frequent power consumption requirements in some applications. It is almost impossible to apply in the occasion of power failure, which restricts the popularization and replacement of electronic control locks. Therefore, the application of electronic locks has been limited to high-end commercial places such as hotels and office buildings, and cannot be widely used in homes; Driven by a motor, it is driven by gears and racks. The electromechanical structure is relatively complex, and installation and maintenance require certain professional skills, which is difficult; the entire mechanism consumes high power, and when a fault occurs, the motor self-locking will block the entire mechanism , so this type of electronic lock must be equipped with an ordinary mechanical unlocking mechanism

For the existing ordinary mechanical lock, if it is to be converted into an electronic lock, the entire lock can only be replaced in the prior art, so it cannot be well integrated with the traditional mechanical lock, the replacement cost is high, and it is not conducive to popularization and application.
