Description

Blind lock

Technical field

The utility model relates to a kind of lock, particularly a kind of blind lock without key.

Background technology

At present, the lockset that people use has varied, lock that uses key or the coded lock that does not use key are generally arranged, most lock is to use the lock of key, this lock has a lock body, and a lockhole is arranged on the lock body, is connected with lock core in lockhole, corresponding hole is arranged on the sidewall of lockhole and lock core, pellet shot from a slingshot and spring are installed in the hole; Also having part is coded lock, and coded lock has a lock body, and lock core is arranged on the lock body, and figure disc is arranged outside lock core, because the safety of coded lock is relatively poor, the people of the lock that accesses to your password is reducing gradually.The type of lock has padlock or built-in lock, no matter be that any lock all need be installed in outer side of door, so-called built-in lock at least also needs tapered end key hole is installed in outer side of door, that is to say and lock need be installed in the people's sight scope, lock could normally use like this, therefore just to thief provide bump, pound, prize, not Suo possible, make thief be easy to go smoothly, lock will lose due effect.

Summary of the invention

Technical problem to be solved in the utility model is: lock is installed in the too late position of people's sight line, does not use the blind lock of key during unlatching, therefore just avoided thief bump, pound, prize, not Suo possibility.

Solve the technical scheme that its technical problem adopts: this lock has one, and order is socketed with front apron, spring on axle, and positioning disk is socketed on the axle with remembering after code-disc is connected, and is connected with pin on axle, and is fluted on positioning disk.

One end of axle has one section to be the semicircle axle, respectively is connected with a pin in positioning disk position and note code-disc rear, and the other end of axle is connected with handle.

Front apron is a lid, and there is a through hole at the lid center, on the inwall at the edge of lid two annular steps is arranged, and annular step and through hole are concentric circles.

Positioning disk is a disk, disc centre has a through hole, at disk an annular step is arranged, step and through hole are concentric circles, and a groove is arranged on the inwall of through hole, and eight grooves are arranged on the lateral wall of positioning disk, the length of groove is half of positioning disk thickness, half is a groove ends, and second half is the disk end, is connected with baffle plate at the end face of disk end.

The note code-disc is a disk, the centre bit of disk is equipped with a through hole, at the inside wall of through hole eight grooves is arranged, and disk border has the wall of round barrel shape to extend to two directions, there is annular to protrude in the outside of disk border wall, on the outer wall that annular is protruded, is connected with three-dimensional mark.

Beneficial effect: owing to adopted such scheme, when opening this lock, rotation note code-disc, only with hand touch the three-dimensional mark of protrusion on the note code-disc, when making a plurality of marks consistent with the setting mark, the axle at lock center is promptly movable, thereby lock is opened, also lock can be opened owing to not be used in the people's sight scope, so lock can be installed in the too late place of people's sight line, promptly avoided thief bump, pound, prize, not Suo possibility, solved technical problem to be solved in the utility model.This lock construction is ingenious, does not need key to use, and is applied widely, lockset is installed in the too late place of people's sight line, and can use is needing the higher place of safety factor, can not avoid anyone when opening lockset, strong security, it is good that firm uprising power is damaged performance.
