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.And the patent No. is by lock housing for " the eight key mechanical locks " of " 012114103 ", be contained in key core and key axle in the lock housing, be contained in the thumb wheel on the key axle, the stroke plate that matches with thumb wheel, the dead bolt that is connected with stroke plate termination, insert the handle axle in the stroke plate, be contained in the handle at handle axle two ends, be located at gear shaft and the reset key that has tooth bar in the lock housing, the carry gear that cooperates with gear shaft, counting gear, the carry clamp that cooperates with counting gear and key axle constitutes with the cam that joins by strong device with being located on the gear shaft, owing to increased by strong operation part, has pick-proof, anti-drilling, safe and reliable characteristics, owing to adopt by strong password be set, make the lockset size of key can reach 10 ⁶, have the advantages that application operating is convenient, be difficult for decoding.But also there are the following problems for this eight keys mechanical lock: 1, offing normal by two tension spring returns of counting gear, because tension spring is installed between two axles, operation is had any problem, and is subjected to Influence from Eccentric after the installation, causes axle unstable.2, because compression spring and steel ball lean press key pole, impel press key pole and carry gear to rub, make button not go back to the position.3, the isolation of reseting gear, carry gear and counting gear is finished by three parts, and trouble is installed.4, location adjustment is located on the reseting gear, and difficulty is installed, and it is undesirable to adjust precision.5, the horizontal, vertical groove of processing causes mutual screens on the handle axle, and stuck phenomenon takes place handle often.

Summary of the invention

The objective of the invention is to provide that a kind of can freely to encode, change sign indicating number convenient, pick-proof, anti-drilling, preventing decryption, installs quick and convenient, use comfortable, precise control, safe and reliable, the mechanical code lock of no screens phenomenon generation.

The present invention is achieved in that it comprises lock housing, establish the carry clamp in lock housing, being provided with, the dead bolt of ring open controlling organization and in establish the stroke plate, the handle axle, handle and the flexible executing agency of the dead bolt that is located at the compression spring in the handle, in lock housing, also be provided with by reseting gear, carry gear and counting gear and reset strong, carry key letter and key card, the digital code editing mechanism of card and clutch clamp formation is paid in clutch shaft and clutch, the strong insertion lock housing that resets inside is arranged with tooth bar, its special character is: on the counter axis of counting gear, the lower end is provided with power spring, the other end of power spring withstands on the carry clamp, corresponding tooth bar and key Ka Chu are equipped with block in lock housing, corresponding tooth bar place is provided with the levelling frame on block, in the levelling frame, compression spring and steel ball are installed, said steel ball withstands on the tooth bar, corresponding every group of reseting gear on block, the gap location of carry gear and counting gear is provided with distance piece, on the carry gear, be provided with gap, to being provided with power spring and steel ball by opening position, corresponding pressure spring place is set with the gear circle on handle on block.

Above-mentioned mechanical code lock is provided with the levelling plate between levelling frame and block.

Above-mentioned mechanical code lock stretches out the lock housing end at tooth bar and is provided with spacing anticreep screw, and position-limiting action when working full and anti-reset key break away from.

Above-mentioned mechanical code lock, corresponding clutch clamp place is provided with the location deck in lock housing, waves and breaks away to prevent the clutch clamp.

Advantage of the present invention is:

1, freely encode, but the layout of carry key singly-bound can make up mutually again, combination is digital unrestricted.Whenever advance one by a key, follow carry after the carry again.All can't unblank as the difference poor, order that the position is arranged when the button, therefore be difficult to decode.

2, change sign indicating number conveniently, when this mechanical code lock is in open mode, change yard key insertion changing a code holes, Rotate 180 ° pressurization with special use, rotate 10 ° of angles again, key blocks, and can import new combinational code, and the taking-up key circles round, by reset key, new sign indicating number deposits in, and old sign indicating number is removed, and the change scope is wide, speed is fast.

3, handle is correctly unblanked in waiting plane, ejects automatically, and positive and negative half-twist can be controlled multidirectional many tongues switch,, uses safely by advancing with the back, and is remarkably productive.

4, but dead bolt unlatching controlling organization can adopt and turn round also key formula structure of minor structure, and interchangeable.Turn round the minor structure and be provided with the exertin protection, the non-super power sky of correctly unblanking revolves, and can prevent to lock the generation of phenomenon by mistake.

5, the carry key can be made as seven, key precision height, and size of key can reach 10 ⁶

6, 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.
