Description

Ten purpose cipher cylinder lock for door

The utility model is to belong to a kind of pin tumbler lock, more particularly relates to a kind of pin tumbler lock that Cipher mechanism is arranged.

Existing pin tumbler lock, as the dual fail-safe pin tumbler lock, three insurance pin tumbler lockes mainly insert lock core with key, rotate the transmission bar and open the door.Pin tumbler lock is made up of five groups of pellets shot from a slingshot, though its variation has kind more than 3,000, also exists certain repetition open amount.And pin tumbler lock can only turn the key in the lock, and when forgeing when carrying key or key and losing, often brings worries to people, have to force open the door or force open the door.Moreover key is tangible thing, duplicates steathily also can for the person of being not good at and open.Still do not have a kind of available key at present, or open the door with password without key, or both pin tumbler lockes that access to your password simultaneously of password, key.

The purpose of this utility model provides a kind of not only with password but also the pin tumbler lock that turns the key in the lock, to improve its confidentiality.

The another purpose of the utility model provides when not carrying key, and the pin tumbler lock that can access to your password and open the door is easy to use, and confidentiality is good again.

The utility model purpose is realized by following technical scheme.

The utility model is by key, and tapered end and lock body are formed.In the described tapered end lock core is arranged, pellet shot from a slingshot and spring are arranged in the lock core, lock core has lock tube outward, and the transmission bar is made up of the end that latch is fixed on lock core.Described lock body, by dead bolt is arranged in the lock housing, dead bolt connects the dead bolt planker, and base plate is arranged at the lock housing bottom, and the base plate cam is arranged on the base plate, is made up of handle on the lock housing, it is characterized in that:

On a, the described tapered end at least three combination disk are housed, on the combination disk outer wall cipher symbol are arranged, a macropore and the aperture that has at least more than 20 are being arranged on the combination disk inwall, equalization sets up cloth separately;

In b, the described tapered end, the lower end inserting the lock core key plate matches with combination disk, has three above positioning ball springs at least;

C, insert the key in the lock core, in the tapered end of its both sides, have at least more than three with the combination disk inwall on the ball spring that matches of hole;

D, described lock tube outer end are linked to each other with handwheel by screw;

E, described handle are the stretching rotational structure, and described stretching rotational structure connects the handle axle by handle, and the handle axle other end penetrates in the lock housing, on the handle axle spring is arranged, and handle is connected on the lock housing by the handle axle sleeve to be formed;

F, described dead bolt planker have a manhole on the rear end, and the diameter in its hole matches with the diameter of handle axle, has slot in the dead bolt middle-end, in its hole block is housed, and block connects block shaft, and spring is housed on the block shaft.

The utility model has following advantage:

1, the utility model is organically combined together by password and cylinder lock.Both can password and the key time spent use, again can be, singly open the door with password without key.

2, the password be made up of combination disk of the utility model has 450,000 above combination pins and opening ways different more than 1,400,000,000 kinds, the privacy degrees height.

3, the utility model simple structure is elegant in appearance, and is easy to use, safe and reliable, and ten big functions are arranged:

A, key, password assurance mutuelle, b, coding insurance, c, anti-prying, d, the indoor anti-insurance of opening, e, anti-folding insurance, f, anti-self-locking safety, are outdoorly anti-ly opened insurance at g, and h, burglary insurance, can not turn the key in the lock at i, and j, secret dish can replace door handle.
