Description

Puzzle spring lock

The utility model relates to a kind of password night lock.

The cylinder lock that is widely used at present is of a great variety, form each one.Their common feature is that screw key drives lock core and rotates and lock is opened when utilizing the height of shaped as key bit to make lock core marble be in the plug face position.If profile of tooth is not to just opening.Owing to often use the key can formation abrasion, often make and unblank ineffectively, key need be carried very inconvenient.Only with a key, reliability and theftproof are poor usually for common cylinder lock.

The purpose of this utility model is to provide a kind of password night lock without key.

The technical solution of the utility model is: letter disk is cooperated with pellet shot from a slingshot, lock housing, lock core, and directly rotational lock core does not need other bitting; One or more groups pellet shot from a slingshot is set on lock core or lock housing, after rotation letter disk password makes one group of pellet shot from a slingshot alignment, lock core can be rotated an angle and be pinned, rotate again this moment and could again lock core be rotated after the letter disk password makes second group of pellet shot from a slingshot alignment by second group of pellet shot from a slingshot.If three groups of pellets shot from a slingshot are set on the lock housing, need so three passwords, lock core is rotated lock could be opened for three times, if four groups of pellets shot from a slingshot are set, so just need four passwords are so analogized.Therefore the reliability and the confidentiality of this lock have improved exponentially.

Be described further below in conjunction with drawings and Examples.

The utility model is made up of lock core (1), lock housing (2), letter disk (4), collar (3), taper pin (8) and pellet shot from a slingshot and spring.Lock core is positioned at the centre of lock housing, and the lock housing periphery is wrapped in by letter disk.In order to prevent moving axially of letter disk, one is blocked by lock core or lock housing end face, and the other end is blocked by the collar that is enclosed within on the lock housing, and collar is fixed on the lock housing by taper pin.

Be drilled with row's pellet shot from a slingshot hole on the lock core, spring and pellet shot from a slingshot are set in the hole, can bore a row pellet shot from a slingshot hole on the lock housing as required or arrange the pellet shot from a slingshot hole more, spring is arranged on the central authorities in hole, two is provided with pellet shot from a slingshot respectively, and a pellet shot from a slingshot is corresponding with lock core marble, and the other end pellet shot from a slingshot contacts with the letter disk inner ring.The letter disk inner ring is shaped as irregular circle-arc tooth, has been equivalent to curve the key of a circle.

Earlier pellet shot from a slingshot group and spring are prepared during assembling, lock core inserted lock housing and to good hole, put into pellet shot from a slingshot and spring, again letter disk is packed into lock housing, putting retainer makes and is close to the letter disk end face, with taper pin collar is fixed, just become the password night lock tapered end, mixing lock body and connector (tongue bars) more just becomes password night lock.

Embodiment 1

As shown in Figure 2, lock core is established hole one row, and spring and pellet shot from a slingshot are set respectively in the hole, and lock housing is established hole three rows, and the middle part is provided with spring in the hole, and two is provided with pellet shot from a slingshot, the spring on the lock core and pellet shot from a slingshot respectively with lock housing on spring marble and letter disk teeth groove be made into three groups of passwords mutually.When unblanking, dial one group of password earlier, can change an angle, dial second group of password again, change an angle again, lock could be opened three passwords continuously.

Embodiment 2

As shown in Figure 3, lock core is established through hole one row, only establishes pellet shot from a slingshot in the hole, and does not establish spring, and lock housing is established hole four rows, and symmetrical in twos, spring is established at the middle part in the hole; Two is provided with pellet shot from a slingshot, the pellet shot from a slingshot on the lock core respectively with lock housing on spring marble and letter disk teeth groove be made into four groups of passwords mutually.Dial lock core being changeed an angle behind two groups of passwords earlier when unblanking, lock could be opened two groups of passwords again.
