Abstract

The utility model discloses a coded door lock, which is suitable for being installed on wooden doors and safety iron door. The coded door lock is mainly composed of an inner lock box, an outer lock box, a bolt sleeve, and a plurality of connecting pieces. When the coded door lock is unlocked, the key is not needed, the door being locked by the coded door lock can be opened by the quantity of the cipher on a cipher wheel; the outside of thedoor does not have the definite quantity of the cipher, and the coded door lock is unlocked by the hand feeling of the toggled cipher; the security is good thereby.

Description

A kind of cipher door lock

The utility model relates to the password number of the usefulness of locking a door.

The door lock of the common usefulness of people has spring padlock and pellet shot from a slingshot built-in lock two classes, all be unable to do without key when this two class lock is opened, because key carries that inconvenience is lost again easily or be stolen, thereby is unblanked to result in hand cramps.

The utility model discloses a kind of nothing to the public and posts key, and the door coded lock that is difficult to divulge a secret when unblanking.

The utility model mainly is made up of the connector that interior lock box, outer lock box, lock bolt sleeve and some connect inside and outside lock box.Lock bolt sleeve is identical with the lock bolt sleeve of built-in lock with common door, just its dead bolt hole has only one, interior lock box has a rectangle box shell, one on box shell is equipped with a square dead bolt, the dead bolt back is connected with a dead bolt tightening latch, and the dead bolt tightening latch is microscler square bar, and it is positioned at separates on the code wheel wheel, when it was in the lock lock-bit, it is gone to the bottom respectively had a lock locking bolt near each position of separating the code wheel front side.The dead bolt tightening latch is equipped with one near rear end and moves back the bolt spring, and dead bolt tightening latch rearmost end is a hemispherical ejection.Be close to below the dead bolt tightening latch and mediate code wheel, separate the code wheel number and should not be less than 3, each separates code wheel all a decoding breach that crosses the wheel center, this decoding breach size should be complementary with the lock locking bolt size that the dead bolt tightening latch is gone to the bottom, separate and be the transmission bevel gear below the code wheel, this gear is being connected the corresponding bevel gear of outer lock box by a umbrella shape tooth axle that laterally passes through doorframe, below interior lock box transmission bevel gear cipher wheel is installed, the cipher wheel circle is carved with " 01234567890123456789 " 20 password numbers on the side successively equably.Lock box was strengthened on the diaphragm down in the lower shaft of above-mentioned three-wheel was installed in, and last axle is installed in an auxiliary transverse rod strip.In dead bolt tightening latch back the pull bar of unblanking is housed, unblank pull bar perpendicular to the dead bolt tightening latch and run through interior lock box, doorframe and outer lock box, one energy pushing tow dead bolt tightening latch rear end hemisphere ejection hemispherical ejection forward when lock pins is arranged at the middle part that this pull bar of unblanking is positioned at the lock box section, in this ejection back one pushing top spring is housed, this spring force must move back the elastic force of bolt spring greater than the dead bolt tightening latch, and pushing top spring withstands on the interior lock box bonnet.Unblank pull bar expose in lock box outer appear on be equipped with one and unblank to draw handle.Be contained in the outer outer lock box of doorframe and have one in shape and size and the corresponding box shell of interior lock box box shell, just have one to hold in the pull bar of unblanking the interior circle of handle recessed more in the exit of the pull bar of unblanking, in the position corresponding corresponding transmission bevel gear and cipher wheel are housed equally also with interior lock box transmission bevel gear and cipher wheel, just the outer ring, last plane of each outer lock box bevel gear is processed with the shallow round recessed that 20 even distributions are used to hold the password a brief period of time, one vertical a brief period of time tubule is housed on diaphragm on the box shell of this shallow round recessed, a brief period of time pipe internal upper part is equipped with a brief period of time spring, spring heads on the following a brief period of time, and a brief period of time withstands in the shallow round recessed of a brief period of time of outer ring, plane on the transmission bevel gear.In addition, be positioned on the cipher wheel circle side below this transmission bevel gear and do not have password number " 123 ... ", and just the position between interior lock box cipher wheel circle side password number " 0 " and " 9 " be carved with private mark sign " ° " " " or other simileys.The upper and lower axle branch of above-mentioned two-wheeled is installed on the upper and lower reinforcement diaphragm of outer lock box box shell in addition.The part that the pull bar that opens the door runs through outer lock box is a common round bar, just on its external end head a circular handle is housed, and this handle size should be complementary with the recessed size of interior circle on the outer lock box shell.The connector that connects inside and outside lock box has the umbrella shape tooth axle of bevel gear in the inside and outside lock box of transmission, this umbrella shape tooth axle two respectively have one with inside and outside lock box in the small umbrella gear that is complementary of the bevel gear gear teeth, its power transmission shaft is enclosed in the smooth pipe spreader, and pipe spreader runs through doorframe.Connector also has several connecting screw rods, and connecting screw rod passes doorframe and straining inside and outside lock box.The pull bar of unblanking also passes doorframe and is connecting inside and outside lock box, and the part that it passes through doorframe equally also is with a pipe spreader.

The utility model has following advantage compared with traditional door lock: the one, unblank need not key, as long as remember password, to good password, push-and-pull unblank pull bar, the lock promptly open.The 2nd, good confidentiality, the outside wheel of maintaining secrecy does not have the password number, only relies on the thumb wheel sense of touch and unblanks, thereby avoided the possibility of other people's password number directly perceived, has increased confidentiality.
