Abstract

The utility model discloses a cylinder lock with a plurality of holes, which is a novel cylinder lock. The cylinder spring (4) of the cylinder lock with a plurality of holes is arranged in the cylinder control hole of a lock core. Various door locks and cycle locks can be made through the design scheme. The cylinder lock with a plurality of holes is characterized in that the cylinder lock with a plurality of holes is provided with two or more than two unlocking holes (13) which are arranged on the outer sleeve of the lock core; a key is plunger-shaped. The utility model has the advantages of simple manufacturing technique, low cost, convenient unlocking, easy repair, and strong safety property.

Description

Cylinder lock with multiple opening holes

The utility model relates to a kind of improved cylinder lock, and particularly a kind of cylinder lock that two or more key operated holes are arranged can be made various door locks and lock.

Existing cylinder lock majority has only an open hole, and all marble lock keys are that sheet is zigzag; When cylinder lock was opened, key inserted earlier in the cylinder lock open hole, then rotational lock core.There is following problem values to discuss: owing to the mode of operation of manpower and the reason of key shape, the scope of design of the thickness of key, length and the number of teeth just is restricted, like this, the kind of design cylinder lock, particularly design high-intensity cylinder lock certain difficulty is just arranged, and existing cylinder lock is when the repair key, all need take lockset apart, pour out pellet shot from a slingshot and just can carry out, quite trouble.

Task of the present utility model is to provide a kind of design scheme of new marble lock, requires manufacturing process, manufacturing cost, opening ways, the kind of design and the repair of intensity and key of this cylinder lock all to be better than existing cylinder lock.

Task of the present utility model is finished as follows: the control mode of using existing cylinder lock, marble spring is installed in the lock core marble control hole, according to pellet shot from a slingshot group number, design two or more open holes and open hole on lock core sleeve, key is to be fixed on the plunger shape that constitutes on the lever by the different short column of two or more length.Key is inserted open hole, the short column compression marble spring of key, lock core just can rotate or axially-movable, thereby reaches the purpose of opening of control cylinder lock.Change the key short column what, length, put in order, spread geometry and mutual alignment, can make various cylinder locks, can accomplish equally to open different locks with different keys.Also have, because the length of key short column can measure easily, the user can needn't pour out pellet shot from a slingshot according to known key dimension of picture repair key.

Obviously, can make than the more cylinder lock of existing cylinder lock kind by the utility model design scheme, its intensity and reliability also can design more as required, have manufacturing process simple, with low cost, open convenient, repair easily, the advantage of high safety.

Below in conjunction with accompanying drawing enforcement of the present utility model is further described.

Accompanying drawing 1 is that the utility model lock core, locking bolt and slide bar are the revolved section structural representation (omission fabrication hole) that integral body and lock core shaft open to motion control.

Accompanying drawing 2 is the utility model key shape figure.

Accompanying drawing 3 is schematic diagrames that the utility model is used for bicycle lock.

What the utility model was identical with existing cylinder lock design scheme is: also be made up of lock core (12), lock core sleeve (3), marble spring (4), back pellet shot from a slingshot (5), preceding pellet shot from a slingshot (7), spacer pin (6), chute (11), locking bolt (1) and key.Different is: marble spring (4) is installed in the pellet shot from a slingshot control hole of lock core (12), open hole (13) has two or more, and design is on lock core sleeve (3), key is a plunger shape, lock core (12) is (existing cylinder lock is the garden cylindricality) except that the garden cylindricality is arranged, and also has prismatic (when lock core (12) axially-movable control is opened).(8) are cover plate among Fig. 1, and (2) are power spring.

Now narrate the utility model course of work at the application drawing on the bicycle lock 3 and in conjunction with Fig. 1 and Fig. 2: in key inserts the open hole (13) of lock core sleeve (3) with the utility model, the key short column is just by preceding pellet shot from a slingshot (7) and back pellet shot from a slingshot (5) compression marble spring (4), after putting in place, lock core (12) drives locking bolt (1) and moves upward automatically under the effect of power spring (2), bicycle lock is promptly opened; Extract key out, hand is pressed lock core (12) upper end slide bar (10), stirs bicycle lock ring (9) simultaneously, and bicycle can pin.

Claims

1, a kind of cylinder lock of forming by lock core (12), lock core sleeve (3), marble spring (4), back pellet shot from a slingshot (5), preceding pellet shot from a slingshot (7), locking bolt (1), spacer pin (6), chute (11), key, it is characterized in that marble spring (4) is installed in lock core (12) the pellet shot from a slingshot control hole, open hole (13) has two or more, and design is on lock core sleeve (3), and key is a plunger shape.
