Abstract
The utility model relates to a mechanical lock which is provided with a locking head with adjustable position and can be prevented from being unlocked by violence. The utility model aims to ensure that the lock can be mounted and used on doors with different thickness and the locking head is prevented from being damaged by pulling and poking tools and other tools. The position of the locking head on a lock case and a protective ring which is used for preventing a drilling bit from being drilled on a lock body and can be freely rotated can be adjusted by adopting an adjustable structure. The mechanical lock comprises the lock body, the locking head, a lock core, a spring and a marble pair. The lock core (10) is mounted in the hole of the locking head (7); the locking head is fixed in a fixed sleeve (7) by a bolt (4); and the fixed sleeve is fixed on the lock body. Two rows of two to three holes (6) are formed on the fixed sleeve; and the locking head can be fixed in one of the holes. In order to prevent the lock from being unlocked by the violence, a movable sleeve (10) is sleeved on the locking head, is connected with the locking head by a clamp spring (9), and can be freely rotated; and a movable key door ring (2) is mounted in the hole on the end surface of the movable sleeve and can be freely rotated. The movable sleeve and the movable key door ring are made of alloy steel after being subjected to heat treatment and can prevent the drilling bit from being drilled. The utility model has the advantages of simple and reliable structure and convenient adjustment and ensures that the lock can not be damaged by the violence of the drilling bit.
Description
Technical field:
Utility model: a kind of tapered end position can be in harmonious proportion anti-riot power mechanical lock opened, belongs to mechanical lock, is fit to do two flappers locks especially.
Back of the body border technology:
Total class of lock is a lot, mechanical lock, electronic lock, acoustic control lock is arranged, shake control lock etc.Mechanical lock be mainly by tapered end, lock body, lock core, spring and pellet shot from a slingshot to forming, tapered end is contained in the lock body opening, lock core is contained in the tapered end hole, spring and pellet shot from a slingshot be to being installed in the corresponding mutually position of lock core and tapered end respectively, becomes retaining mechanism, opens the lock with the key.The structure of this lock is simpler, and cost is low, and install, safeguard easily, be the lock that current people generally adopt.But mechanical lock also has shortcoming: (1), theftproof performance are relatively poor: destructive way such as dialled, reverse and unblank by drawing by general purpose tool easily; The violence mode of also available sled, brill is destroyed tapered end and is unblanked.(2) if as door lock,, can not adjust, so with a kind of lock, it is more suitable only to install on the door of respective thickness because the fixed-site that tapered end is fixed on the lock body is constant.(3) when with the bit drills lock core, can drive tapered end and rotate simultaneously and reach the purpose of unblanking.
Summary of the invention:
The utility model proposes a kind of tapered end position and can be in harmonious proportion anti-riot power mechanical lock opened, its objective is to overcome the existing shortcoming of lock, lock can be installed and used on the door of different-thickness.Another purpose is when with the bit drills lock core, to prevent that lock gall from rotating simultaneously; Prevent with instrument such as drawing, dial to destroy tapered end.
The technical solution of the utility model is that adjustable structure is adopted in the position of tapered end on lock housing; The anti-drilling retaining ring that can freely rotate is arranged on lock body.
A kind of tapered end position can be in harmonious proportion anti-riot power mechanical lock opened, comprise that lock body, tapered end, lock core, spring and pellet shot from a slingshot are right, lock core is contained in the tapered end hole, tapered end is installed in lock body, spring and pellet shot from a slingshot are to being installed in the corresponding mutually position of lock core and tapered end respectively, it is characterized in that there is tunable arrangement the position of tapered end on lock body: comprise tapered end and fixed cover, fixed cover is fixed on lock body, tapered end has screwed hole, 2-3 holes corresponding with screwed hole are arranged on the fixed cover, tapered end is fixed on the fixed cover with bolt.
Above-mentioned a kind of tapered end position can be in harmonious proportion anti-riot power mechanical lock opened, the end that it is characterized in that described tapered end is equipped with movable sleeve, and movable sleeve is enclosed within on the tapered end, and interconnects with jump ring, movable sleeve can freely rotate, and the movable sleeve end face is porose to be used with lock core spoon door.
The hole of correspondence on above-mentioned screwed hole and the fixed cover is characterized in that having on the tapered end two corresponding with it on two screwed holes and fixed cover rounds, and every row has 2-3 holes.
Above-mentioned movable sleeve is characterized in that the spoon door that movable spoon knocker and lock core are housed in the described movable sleeve end-face hole is used, and movable spoon knocker can freely rotate.
Movable sleeve and movable spoon knocker are through heat treated alloy steel, can stop drill bit to pierce movable spoon knocker.
The utility model is adjusted lock body position simple in structure, reliable, easy to adjust on lock housing.A movable sleeve and a movable spoon knocker prevent that effectively violence from unblanking.Because a movable sleeve and a movable spoon knocker can be followed drill bit and be rotated, drill bit is produced skid and can not pierce movable spoon knocker.
Description of drawings:
