Description

Padlock
Technical Field
The present invention relates to mechanical locks, and in particular to padlocks.
Background
The lockset has wide application in daily life. Existing locks generally fall into two broad categories: mechanical locks and electronic locks, and mechanical locks are divided into ordinary mechanical locks and coded mechanical locks.
The common mechanical lock has lower manufacturing cost and the most extensive application, but has poor confidentiality, the key is easy to copy, the key is thick and heavy, and the common mechanical lock is inconvenient to wear when going out. In addition, when the mechanical lock is to be replaced, it is generally troublesome to replace the entire lock cylinder or replace the lock cylinder.
The mechanical combination lock does not need to wear a key, but needs to remember the combination, and the number to be remembered by people is too many and is easy to be confused.
The security of the electronic lock is higher than that of the mechanical lock, but a special decoding circuit is required to be arranged, the lock is complex to manufacture, the cost is high, and faults are easy to occur due to the adoption of a large-scale integrated circuit.

The password block is of a rectangular plate structure and is matched with a drilling card for use, a sliding block is arranged in the password block, a plurality of pin pairs are distributed on the sliding block, a lock pin is arranged at the front end of the password block, a card slot is formed in the password block, a plurality of card holes are distributed on the drilling card, and when the drilling card is inserted into the card slot and the card holes of the drilling card are matched with all the pin pairs in the sliding block, the sliding block can be pushed forwards to drive the lock pin to move inwards.
The side of the cipher block groove in the lock body corresponding to the lock pin of the cipher block is transversely provided with a lock pin opening and a lock pin clamping groove, and a spline groove is arranged right in front of the cipher block groove.
Spline groove and cipher block groove pass through spline notch intercommunication, the left and right sides in spline groove is opened respectively has the spline mouth that communicates lockhole and lock tongue hole, a pair of spline has been placed respectively to the both sides in spline groove, a layer board is violently placed in the middle part, the spline is the arc structure, its back has the lug, the belly has the boss, open at the middle part in spline groove has layer board spring hole and has placed the layer board spring, the layer board compresses tightly the spline through the lug under the effect of layer board spring, the afterbody that makes the spline passes the spline notch and is located the cipher block inslot.
The lock is locked, the two ends of the lock tongue are respectively positioned in the lock hole and the lock tongue hole, all the password blocks are positioned in the password block grooves of the lock body, the front ends of the password blocks are abutted to the tail ends of the splines, the front ends of the splines extend out of the spline openings to be inserted into the lock tongue clamping openings of the lock tongue, the supporting plate springs are compressed, and the upper ends of the lock pins enter the lock pin openings of the lock body.
The lock is unlocked, the lock pins of the password block are completely retracted into the password block through the drilling clamping sheet matched with the password, the supporting plate pushes the spline through the convex block under the action of the supporting plate spring, the tail part of the spline penetrates through the spline notch to be located in the password block groove, the front part of the spline is retracted into the spline notch, and the lock tongue is lifted under the action of the lock tongue spring to enable the other end of the lock tongue to be away from the lock hole of the lock body.
The unlocking state is changed into the locking state, and the password block is directly pushed forward and the lock bolt end is plugged into the lock hole at the same time.
The invention has the following outstanding substantive features and remarkable progress.
1. The invention has strong confidentiality, and the code blocks with different codes can be designed by arranging different numbers and positions of the marble pairs as long as more than 10 groups of marbles are arranged in the code block, and the code repetition probability of the code blocks is very small. The possibility of illegal unlocking can be greatly reduced.
2. The invention has simple structure, card type key, convenient carrying, no need of replacing lock liner when replacing lock, only need of replacing cipher block, and easy replacement of cipher block.
