Abstract

The utility model relates to a door lock. After a code adjusting disk, a coding ring and secret code marbles are assembled on a common marble lock, the common marble lock becomes a marble and secret code combined lock. The code adjusting dick of the combined lock is sheathed on the front end of a lock sleeve, a marble hole communicated with a marble hole of the lock sleeve is arranged on the code adjusting disk towards the axis center and the code adjusting disk is also locked by the function of using a lock marble to lock a lock core. In this way, the code adjusting disk can be controlled by a lock key and secret codes can be used or not used according to need. The secret code part of the combined lock locks and unlocks the lock through switching a group of secret code marbles in the lock sleeve between the lock core and the coding ring.

Description

Pellet shot from a slingshot, password combination tapered end

The utility model is a kind of door lock.

Because people to the safety of door lock, the demand of confidentiality, the password combination door lock occurred on the market.But in the life is not to lock a door all to need to enable password at every turn, and the accent code-disc of coded lock is all stirred can leting people outdoors, and this has brought inconvenience to the user.

The purpose of this utility model will provide a kind of exactly and can will transfer pellet shot from a slingshot, the password combination lock of locking code disc.Like this, just can use as required or without password.

The utility model is achieved in that on the lock core of common spring lock, lock tube cover is loaded onto one and transferred a code-disc and a group coding circle, is that rotate in the axle center with the lock tube.Open a pellet shot from a slingshot hole to the axle center transferring on the code-disc, make the shell hole connection of the shell hole transferred on the code-disc and lock tube.Three pellets shot from a slingshot of packing into, wherein second pellet shot from a slingshot equates with the lock tube wall thickness.Like this, when key lock pellet shot from a slingshot jack-up, when lock core can rotate,,, transfer code-disc also can rotate like this so a top pellet shot from a slingshot is also pushed up from lock tube because second pellet shot from a slingshot equate with the lock tube wall thickness.Otherwise, extract key, pellet shot from a slingshot inwardly advances under the effect of spring simultaneously, and lock core, accent code-disc have all been pinned.

In addition, in a side of lock tube, other opens one group of password pellet shot from a slingshot hole, on the corresponding position of adjacent lock core and coding circle, opens the groove or the counterbore that can allow the password pellet shot from a slingshot cut.The password pellet shot from a slingshot that threading is bigger than lock tube wall thickness dimension, one end-grain cutting are gone in adjacent lock core or the coding circle.When needs are enabled password, rotate by transferring code-disc to drive the coding circle, the password pellet shot from a slingshot is pushed in the groove or counterbore on the lock core, lock core just can not rotate like this.Otherwise, the coding circle by the password of setting, is recalled to the original place successively, when making the password pellet shot from a slingshot that the space that moves apart lock core be arranged, lock core just can rotate.When rotating, the password pellet shot from a slingshot has been pushed back again in the groove or counterbore of encoding on enclosing.

The utility model be because can lock the accent code-disc, so just can use as required or without password, practicality can be stronger like this.

Concrete structure of the present utility model is provided by following example and accompanying drawing.

Fig. 1 is the utility model vertical cross section schematic diagram.

Fig. 2 is the utility model horizontal section schematic diagram.

Fig. 3 is a coding circle generalized section.

Further describe concrete structure of the present utility model and mode of occupation below in conjunction with accompanying drawing.

After parts are processed on request, assemble with reference to Fig. 1, Fig. 2.Earlier lock core (1) is put in the lock tube (2), loaded onto lock pellet shot from a slingshot (3), lock spring (4), (except first group) also seals the pellet shot from a slingshot hole.Transferring code-disc (5) to be sleeved on the front end of lock tube (2), also load onto pellet shot from a slingshot, spring again.Refill into password pellet shot from a slingshot (6).Successively coding circle (7) is loaded onto then.Putting lock housing (8) at last can be assembled on the door lock and used.

Unblank to be performed such: at first key is inserted lock core (1), lock pellet shot from a slingshot (3) is backed down, transfer code-disc (5) just can rotate like this.By the transmission of transferring code-disc (5) and coding circle (7) to go up pin (9), by the password of setting, the groove (10) on the circle (7) of will encoding successively transfers to the corresponding position of password pellet shot from a slingshot (6), with key rotation lock core (1), password pellet shot from a slingshot (6) is pushed in the groove (10) of coding circle (7) in lock core (1) counterbore (11), and lock has just been opened.

Claims (3)

1. a pellet shot from a slingshot, password combination tapered end by lock core (1), lock tube (2), transfer code-disc (5), coding circle (7) and lock pellet shot from a slingshot (3), password pellet shot from a slingshot (6) etc. and form, is characterized in that:

A. transfer the shell hole of shell hole on the code-disc (5) and lock tube (2) to connect,

B. password pellet shot from a slingshot (6) is bigger than lock tube (2) wall thickness dimension, and the one end-grain cutting is gone in adjacent lock core (1) or the coding circle (7).

2. tapered end according to claim 1 is characterized in that having one group of lock pellet shot from a slingshot (3) to extend to from lock core (1), lock tube (2) and transfers in the code-disc (5).

3. tapered end according to claim 1 is characterized in that having the groove (10) or the counterbore (11) that can allow password pellet shot from a slingshot (6) be cut on lock core (1) and the coding circle (7).
