Mecanical puzzle lock

Abstract

The invention relates to a kindo f machinery cipher lock. The controlling organization for opening and flexible executive body of the bolt are established in the lock hull. The organization of figure arrangement which are composed of the resetting gear wheel, carrying bit gear wheel, numbering gear wheel, resting key which are equipped with racks, carrying bit code key and key card are also established in the lock hull. Its uniques consists in that on the top and bottom there are the dint spring, ni the lock hull there are blocking piece established corresponding to the rack and key card, while on the blocking piece there are correcting shelf established corresponding to the rack, pressure spring and steel ball are fixed in the shelf. On the blocking piece there are interval slices correspond to the interval places between reseting gear wheel, carrying bit gear wheel and numbering gear wheel, on the carrying bit gear wheel there are openings corresponding to which established dint spring and steel balls, while on the knob corresponding to pressure spring suited blocking circle. The advantage of the invention is that its can be arranged freely, changed conveniently, and it is pick-proof, anti-boring, anti-decoding, fixed easily and swiftly, comfortable to sue, controlled exactly, besides, its works safety, and can't be blocked.

Description

technical field [0001] The invention belongs to a lockset, in particular to a mechanical password lock used on an antitheft door or a safe. Background technique [0002] Existing lockset is made of casing, key core, dead bolt, unlocking actuator, the handle controlled by unlocking actuator, and the shortcoming of this lockset is anti-picking, anti-drilling, poor antitheft performance. And the "eight key mechanical lock" that the patent No. is " 012114103 " is to be made up of lock housing, the key core and the key shaft that are contained in the lock housing, the dial that is contained on the key shaft, the travel plate that matches with dial, and The deadbolt connected to the end of the stroke plate, the handle shaft inserted into the stroke plate, the handles installed at both ends of the handle shaft, the gear shaft and the reset key with the rack in the lock case, and the gear shaft matched The carry gear, the counting gear, the carry clamping plate matched with the cou...

AI Technical Summary

Problems solved by technology

But this eight-key mechanical lock also has the following problems: 1. The off-position of the counting gear is returned by two tension springs. Since the tension springs are installed between the two shafts, the operation is difficult. Stablize

2. Since the pressure spring and the steel ball are pressed against the button rod, the button rod and the carry gear are rubbed against each other, so that the button cannot return to its position.

3. The isolation of reset gear, carry gear and counting gear is completed by three parts, which is troublesome to install

4. The positioning adjustment is set on the reset gear, which is difficult to install and the adjustment accuracy is not ideal

5. The horizontal and vertical grooves are processed on the handle shaft to cause mutual locking, and the handle often gets stuck
