Abstract

The utility model relates to a lockset which is opened and closed by pressing the cipher. The lockset is composed of a lock casing, a cipher key, a Lock core, a spring piece and a steel cable. The lock casing and the lock core are connected into the integration through the steel cable, and the purposes of opening and closing the lock body are achieved by pressing the cipher key when the lock core is inserted into the lock casing after the cipher key is arranged on the lock casing. The utility model has the advantages of no key, flexible open and close, high security, firm anti-pry structure, high safety, etc., and the cipher can be adjusted at any time.

Description

Puzzle lock

The utility model is to belong to a kind of daily lockset, is a kind of coded lock for the daily locking vehicle of people, door and other object.

At present, the lockset on the market generally all is key operated, though this class lockset has its practical part, often because of the forgeing and lose of key, brings inconvenience and restriction for people's use.Though rotary-type coded lock is also arranged on the market, its secret safety factor is extremely low.Common people can open it undoubtedly in ten minutes as long as stir runner in order.The utility model is exactly to have the technical deficiency of lockset now in order to improve, and compares with it, and the characteristics that this coded lock had are: do not need key, password is adjustable at any time, strong security, and pick-proof sound construction, safety can be improved the daily lockset bolt-lock of people service condition.

The utility model coded lock mainly is made up of lock housing, cryptographic key, lock core, spring leaf, wirerope and plastic cement pipe.Wirerope one end riveted joint lock housing, other end riveted joint lock core.Lock housing is provided with several cryptographic keies that passes the positive back side of lock housing and can back and forth press, in the one side of cryptographic key corresponding to lock core.Be provided with the keying groove of biasing, the shape that opens and closes groove is corresponding with the shape of lock core terminal, constitutes the on-off structure of coded lock thus.The center, the back side that opens and closes groove at cryptographic key is provided with the tightening groove; Both sides corresponding to cryptographic key tightening groove in lock housing are provided with locating slot, the centre of the relative two grooves spring leaf of packing into, spacing thus and tightening cryptographic key.

Accompanying drawing of the present utility model has:

Figure one: the general illustration of coded lock;

Figure two: lock housing assembly structure schematic diagram;

Figure three: the schematic diagram of cryptographic key;

Figure four: the schematic diagram of spring leaf;

Figure five: the schematic diagram of lock core;

Figure six: coded lock closure state schematic diagram.

As can be seen from the figure lock housing (1), cryptographic key (2), lock core (3), spring leaf (4), wirerope (5) and plastic cement pipe (6) totally six structural representations of partly forming.Lock housing pipe joint (1.a), lock core pipe joint (3.c), code hole (1.d), open and close groove (2.a), lock core terminal (3.b), tightening groove (2.b), locating slot (1.b), (4.a) be the reed part of spring leaf (4), (4.b) hole for using for the pull spring leaf is the corresponding respectively guide rail that is arranged at lock housing (1) and lock core (3) with (3.c) (1.c).

The utility model coded lock is after encoding intentionally, have only by cipher code set and push cryptographic key (2), when making its keying groove (2.a) unanimity placed in the middle, lock core (3) can be opened smoothly, when lock core terminal (3.b) when opening and closing groove (2.a) inconsistent (being non-encoding state), play the locking effect.

Lock housing of the present utility model (1), cryptographic key (2), lock core (3), by the metal material die cast, spring leaf (4) is by the steel spring plate punch forming, wirerope (5) is the standard wirerope, plastic cement pipe (6) is common plastic cement pipe.

The utility model coded lock be a kind of firmly, safety, desirable lockset easily, the bolt-lock of be particularly suitable for travelling outdoors case and bag, vehicle and other article uses.

Claims (1)

1, a kind of coded lock is mainly by lock housing, lock core, spring leaf, wirerope and plastic cement pipe are formed, the one end riveted joint lock housing of wirerope, other end riveted joint lock core, it is characterized in that being equipped with on the lock housing cryptographic key that several pass the positive back side and can back and forth press, one side at the corresponding lock core of cryptographic key is provided with eccentric keying groove, on lock core, be provided with several and the corresponding lock core terminal of shape that opens and closes groove, open and close at cryptographic key on the center at the back side of groove and be provided with the tightening groove, both sides corresponding to cryptographic key tightening groove in lock housing are equipped with locating slot, and spring leaf is housed in the middle of relative two grooves.
