Description

A kind of mechanical open door gear

Technical field

The present invention relates to a kind of door opener, especially mechanical open door gear.

Background technology

At present, door opener species is a lot, has the modes such as Mechanical Driven, Motor drive, and motor-driven reliability is most It need further to improve, it is mechanical often to there is complex structure, reliability not.

Fingerprint refers to the convex recessed uneven lines of the positive surface skin of finger tips, contains substantial amounts of information, and these lines are in figure It is different on case, breakpoint and intersection point, they is referred to as into " feature " in information processing, these " features " is with uniqueness With it is permanent, therefore a people can be mapped with his fingerprint, by comparing the fingerprint characteristic of unlocking person and guarantor in advance The fingerprint characteristic deposited, it is possible to verify the true identity of unlocking person.However, in the approach for improving Fingerprint Lock reliability, also The design work that numerous values must be explored constantly can be carried out, such as, when there is situations such as too cold weather or power-off, Fingerprint Lock can Its unlocking function can be lost.Although Fingerprint Lock application is more universal, Fingerprint Lock is equally difficult to absolutely reliability, usually Configuration mechanical lock is needed to be prepared for urgent need, such as mechanical code lock is one of selection.Coded lock is one kind of lock, is opened When be it is a series of numeral or symbol.The password of coded lock is generally all to arrange and non-real combination.Partial password Lock only uses a rotating disk, several video discs or cam rotation in lock；Also some coded locks are to rotate one group several to be carved with number The thumb wheel circle of word, directly drives the machinery inside lock.

Many groups of formula coded locks, the bicycle lock of common what lower security setting, using multiple dialing rings.The centre of each circle has recessed Position.One axle at the center of lock, above has the tooth of several protrusions, for blocking dialing ring.When dialing ring goes to correct password combination, lock Just can open.This lock is easiest to open.Many this kind of locks need not know that password can be opened at all.Unless its is interior Parts are made perfect, as long as otherwise axle is pulled outwardly, one of tooth will more tense dialing ring than other.This hour wheel The dynamic dialing ring being tightened up, until hearing slight " card " sound, represents that this tooth has had been enter into correct recess.This step is re-covered, Just lock can be opened quickly.

Rotary disk type puzzle lock, the coded lock on padlock or casket ten thousand can be only one of which rotating disk.Rotating disk promotes back of the body Hou Several balance video discs or cam.Traditionally, rotating disk is moved clockwise to first digit first when opening this lock, right Hou is counter-clockwise Second digit is gone to, so until most Hou one is digital.Generally there is recess on cam, when proceeding to correct password Hou, everybody In line, lock just can be opened.This coded lock is safer, but also non-completely without shortcoming.For example, partial password padlock can be with Tapered end is tensed, right Hou rotates rotating disk until can not move again, so just password can be found out.Also the numeral of some turntable coded locks it Between have particular kind of relationship, be greatly lowered to the combinatory possibility of password.Cheap cipher hang lock can be opened with special liner, And without using password.

The content of the invention

It is an object of the invention to provide a kind of mechanical open door gear, its anti-technology unlocking performance height, compact conformation, performance It is reliable, can be particularly used for the emergent unlocking of Fingerprint Lock.

The technical solution adopted for the present invention to solve the technical problems is：Including lock body（900）, also including knob（801）、 Connecting rod（802）, sleeve（803）, shift fork（701）, drive rod（804）；The knob（801）, connecting rod（802）, sleeve（803）、 Drive rod（804）It is sequentially connected, shift fork（701）Drive sleeve（803）It is mobile, make connecting rod（802）And drive rod（804）Separate or Engagement.The invention has the beneficial effects as follows, its unlocking structure is simple, reliable, is easily worked, and is suitable as routine or meets an urgent need opening Locking device, for example, solve Fingerprint Lock the problems such as be likely to occur failure and cannot unlock.

Further structure is the present invention, the shift fork（701）Chain tongue（700）, dead bolt（700）Connect mechanical code lock. The invention has the beneficial effects as follows, position of the mechanical code lock in lock body can be made to carry out arbitrary placement, its simple structure, operation It is reliable, it is easily worked.

Further structure of the invention is that mechanical code lock includes combination disk（101）, also including panel（200）, rotating shaft （102）, locking plate（605）, adjust code plate（500）, rotating shaft（102）And cam（1022）Drive locking plate（605）Block or decontrol Lockplate（604）, lockplate（604）Movement be capable of achieving unlock or locking；Rotating shaft（102）It is installed on tune code plate（500）, it is mobile Adjust code plate（500）Make rotating shaft（102）Depart from or connect combination disk（101）, in combination disk（101）Depart from rotating shaft（102）State Lower rotation combination disk（101）Realize adjusting code.The invention has the beneficial effects as follows, the digital reduction repetition of password of combination disk combination Property；Locking plate, rotating shaft, the application of code plate is adjusted to improve the anti-technology unlocking performance of mechanical code lock, such as chip locking plate and cam The sound of recess contact is relatively small, it is difficult to hear correct code bit with receiver；And its simple structure；Adjust code plate drive lock shaft It is mobile, realize adjusting the simple structure of code, it is easy to process, low cost of manufacture.

Further structure of the invention is that mechanical code lock also includes backboard（400）, the rotating shaft（102）Be provided with it is close The corresponding axial groove of encoder digital（1021）, rotating shaft（102）Connect cam（1022）, the cam（1022）Outer contacts locking plate （605）, lockplate（604）If breach（609）, locking plate（605）In into and out breach（609）Interval it is mobile；Described turn Axle（102）It is axially positioned on tune code plate（500）After can rotate in a circumferential direction；The backboard（400）It is provided with recessed（402）, the rotating shaft （102）Be provided with it is recessed（402）The projection of cooperation（104）, make the rotating shaft（102）Can be described recessed（402）It is middle along itself Unique circumferential axial direction of making reciprocates.The invention has the beneficial effects as follows, cam, locking plate, lockplate combination after upper lock construction, The quantity of locking plate and password arbitrarily can be set, and which is simple and reliable for structure；Backboard is recessed（402）It is raised with lock shaft（104）Only One circumference is fitted into so that lock core only under unlocking condition is adjusted code plate drive whole lock shafts movements, realizes adjusting code Function, its compact conformation.
