Description

Mechanical code lock

Technical field

The invention belongs to a kind of lockset, particularly a kind of mechanical code lock of using on security door or the safety cabinet of being used for.

Background technology

Existing lockset is to be made of casing, key core, dead bolt, the executing agency of unblanking, handle by the actuating mechanism controls of unblanking, the shortcoming of this lockset be pick-proof, anti-drilling, theftproof performance is poor.Publication number is to open controlling organization and flexible executing agency of dead bolt and reset assembly by lock housing and the dead bolt that is contained in the lock housing for " mechanical code lock " of " CN1587613 ", change a yard clutch component, the carry gear, counting gear, reset key, the digital code editing mechanism that carry key letter and key card constitute constitutes, described reset assembly is to constitute by being located at tooth bar that inserts part in the lock housing on the reset key and compression spring and the steel ball that leans at the tooth bar rear side, with guarantee to reset accurately, the described yard clutch component that changes is to pay card and the clutch clamp constitutes by the clutch that is located at the clutch shaft in the lock housing and is installed in the clutch shaft both sides respectively.This mechanical code lock has been owing to increased digital code editing mechanism, has pick-proof, anti-drilling, safe and reliable advantage, owing to adopt button that password is set, makes the lockset size of key can reach 10 ⁶, so convenient, the difficult decoding of application operating.But along with the further check of practice, the problem of this mechanical code lock also little by little displays: 1, reset assembly relies on compression spring and steel ball location, locatees inaccurately, unreliable, is out of order easily, directly causes lockset to open; 2, reset assembly adopts tooth bar to reset, and reset key ejects when resetting the back carry, if adopt seven key carries, reset key can eject lock housing 25mm, not only causes the lockset profile not attractive in appearance, and is subjected to outside destroy easily; 3, the clutch clamp is positioned at lock housing one side, and therefore corresponding to change code holes off-centre bigger, causes the counting gear axle to tilt easily when offing normal, and gear is be unable to do without, and causes changing sign indicating number.

Summary of the invention

The objective of the invention is to provide a kind of carry and reset accurately, reliable, fault rate is low, good looking appearance, can freely encode, change yard convenient and swift, compact conformation, pick-proof, anti-drilling, preventing decryption, safe and reliable, the mechanical code lock of no screens phenomenon generation.

The present invention is achieved in that it comprises lock housing and guidance panel, in lock housing, be provided with the dead bolt that contains the carry clamp and open controlling organization, flexible executing agency of dead bolt and the digital code editing mechanism of containing the counting gear axle, be respectively equipped with reset assembly in the both sides of digital code editing mechanism and change a yard clutch component, on guidance panel, be provided with reset key, its special character is: described reset assembly is by the reduction torsion spring on the reseting gear axle that is located at digital code editing mechanism, be fixed on the ratchet of reseting gear axle one end, be located at the carry hook at corresponding ratchet place in the lock housing and the margining tablet that resets, the gripper shoe that connects carry hook and reset key constitutes, the described yard clutch component that changes is by the friction plate that is fixed on above the carry clamp, the clutch load plate and the clutch card formation that are installed in the friction pulley in the lock core shaft and are located at the friction plate top, described clutch load plate one side is stuck on the counting gear axle by the clutch card, and opposite side leans on the carry clamp by compression spring.

Above-mentioned mechanical code lock, corresponding lock core shaft place is equipped with lock core on lock housing, to form key formula structure.

Above-mentioned mechanical code lock, the outer end that is positioned at lock housing in lock core shaft is connected with rotating seat, turns round the minor structure with formation.

Above-mentioned mechanical code lock is provided with interior handle in the inner of the handle axle of the flexible executing agency of dead bolt, with the occasion that is used for opening in the needs such as security door.

Advantage of the present invention is:

1, because reset assembly adopts the click form, solve the conventional reset assembly and adopted tooth bar to rely on compression spring and steel ball location, locate inaccurate, an insecure difficult problem, carry and resetting walks accurately, reliably, and fault rate is low.

2, reset assembly adopts the click form, and reset key does not eject when resetting the back carry, and good looking appearance, reset assembly are difficult to be subjected to outside destroy.

3, be to drive friction plate owing to changing yard clutch component by the friction pulley that is installed in the lock core shaft, friction plate drives clutch load plate by changing yard key, the final counting gear axle that drives is realized clutch, and lock core shaft is positioned at the lock housing center, therefore parallel the moving of counting gear axle during clutch, clutch accurately, reliable, make that to change sign indicating number convenient, quick

4, freely encode, but the layout of carry key singly-bound also can be made up layout mutually, combination is digital unrestricted, all follows carry function once carry, and the carry key can be made as seven, and key precision height is turned round the minor size of key and can be reached 4.2 * 10 ⁷, key formula size of key reaches 2.6 * 10 ⁹, all can't unblank as the difference poor, order that the position is arranged when the button, therefore be difficult to decode.

5, pick-proof, anti-drilling, install quick and convenient, use comfortable, precise control, safe and reliable, no screens phenomenon generation can be widely used in finance, national defence, enterprises and institutions and civilian security door, safety cabinet, domestic safe etc.
