Abstract

The utility model relates to a wirerope travelling cipher lock which comprises a lock shell. A digital cipher ring, a lock core which is matched with the digital cipher ring, a collapse-resistant button with a clamping claw and a groove wheel which is engaged with the clamping claw are arranged in the lock shell. The groove wheel is fixed on the inner bottom part of a lock shell cavity by a center pin shaft, the inner ring of the groove wheel is wound by a plate type winding spring, the outer end of the winding spring is connected and wound by a wirerope, and the outer end of the wirerope is connected with a lock tongue which is extended out of the lock shell. The utility model has the advantages of novel design, compact structure, portability, light weight and good anti-theft performance.

Description

Wire rope travelling coded lock

The utility model relates to a kind of pocket wire rope travelling coded lock of travelling outdoors and using.

The various ring locks of selling in the market of travelling outdoors and using as wire rope type, catenated form, latticing type etc., often exist that length is fixed, not flexible, and lock is apart from immutable, and large body and heavy mass such as is not easy to carry at problem, easily is opened simultaneously, and theftproof is poor.

The purpose of this utility model is to overcome the deficiency of prior art existence and provides a kind of pocket wire rope travelling coded lock, the usefulness that it has small and light, the lock distance is variable, use is flexible, be easy to carry, theftproof is good.

The purpose of this utility model is achieved in that a kind of wire rope travelling coded lock, it includes a lock housing, interior being installed with in three groups of numerical ciphers rings and the cipher ring interstitial hole by small rack and big support of lock shell cavity is equipped with the lock core that is complementary with it, the button gram that has claw collapses by little axle and is fixed on the lock core lower end, gram collapses and is connected with spring on the inner termination, be connected and fixed by gripper shoe, collapse the sheave that claw is meshed with button gram and be fixed on the lock shell cavity lower curtate by central pin shaft, be wound with board-like wind spring in the sheave chamber on the central pin shaft, the outer ring is wound with wire rope, wire rope is inner to be connected with the wind spring outer end, and the wire rope outer end is connected to have stretches out the outer dead bolt of lock housing.Extended or the withdrawal of wire rope is convenient to lock object.

Adopt technique scheme, have light and flexible, lock apart from characteristics variable, that the emergency requirement energy is antitheft, key adopts password figure in addition, is difficult for by other people identification, and theftproof is strong.

Below in conjunction with drawings and Examples in detail the utility model is described in detail.

Fig. 1 is the utility model structure sectional view.

As shown in Figure 1, a kind of wire rope travelling coded lock, it includes a lock housing (1), be installed with in three groups of numerical ciphers rings (2) and cipher ring (2) interstitial hole by small rack (4) and big support (5) in its lock housing (1) chamber the lock core (3) that is complementary with it is housed, the button gram that has claw collapses (6) and is fixed on lock core (3) lower end by little axle (7), gram collapses and is connected with spring (8) on (6) inner termination, be connected and fixed by gripper shoe (9), collapse the sheave (10) that (6) claw is meshed with button gram and be fixed on bottom, lock housing (1) chamber by central pin shaft (14), be wound with board-like wind spring (13) on the central pin shaft (14) in sheave (10) chamber, the outer ring is wound with wire rope (11), wire rope (11) is inner to be connected with wind spring (13) outer end, and wire rope (11) outer end is connected to have stretches out the outer dead bolt (12) of lock housing (1).During use, the hand push button gram collapses (6), making gram collapse (6) inner termination by little axle (7) lifts, claw breaks away from sheave (10), left-handed can outwards elongation of wire rope (11) by dead bolt (12) connection, the wind spring (13) that connects wire rope (11) also along central pin shaft (14) to anticlockwise, wind spring (13) revolves tighter and tighter, after the length of wire rope (11) can be passed the object that will lock, the dead bolt (12) that will be connected on wire rope (11) external end head inserts in the middle lock core (3) of numerical ciphers ring (2), loosen gram and collapse button (6), collapse at gram under the effect of the spring (8) on (6) inner termination, gram collapses (6) claw and engages sheave (10) and can not rotate, simultaneously, turn is three groups of numerical ciphers rings (2) once, dead bolt (12) are blocked and withstand gram collapse (6), dead bolt (12) can not dialled and is restrained and collapses (6) also by motionless, plays and pins antitheft effectiveness.When unblanking, rotate the numeral on known three groups of cipher rings (2), unclamp dead bolt (12) and can transfer to, under the reaction force of the wind spring (13) of wire rope (11) in sheave (10) that relaxed this moment, the rotational automatic to the right withdrawal of steel rope (11) is easy to carry.

Claims

1, a kind of wire rope travelling coded lock, it includes a lock housing (1), it is characterized in that: be installed with in numerical ciphers ring (2) and cipher ring (2) interstitial hole by small rack (4) and big support (5) in lock housing (1) chamber lock core (3) that is complementary with it is housed, the button gram that has claw collapses (6) and is fixed on lock core (3) lower end by little axle (7), gram collapses and is connected with spring (8) on (6) inner termination, be connected and fixed by gripper shoe (9), collapse the sheave (10) that (6) claw is meshed with button gram and be fixed on bottom, lock housing (1) chamber by central pin shaft (14), be wound with board-like wind spring (13) on the central pin shaft (14) in sheave (10) chamber, the outer ring is wound with wire rope (11), wire rope (11) is inner to be connected with wind spring (13) outer end, and wire rope (11) outer end is connected to have stretches out the outer dead bolt (12) of lock housing (1).
