Description
Technical field
The utility model relates to mechanical code lock, specifically is meant the dial-up mechanism of stirring combination disk that a kind of mechanical cipher is locked.
Background technology
Mechanical code lock is applied to safety cabinet, file cabinet, security door, silver vault door widely now, even has been applied in the family.Its basic functional principle is mostly consistent, at outer side of door the dial of being with scale is set, and the dial of high-grade rotating disc type mechanical code lock is simultaneously also as unlocking handle; It is marked with the scale of band numeral, also claims to unblank handwheel, is furnished with some notched disks on the inboard mandrel that is provided with of door; The main shaft of dial stretches into an inboard and is fixedly connected with mandrel, the outer dial of rotary door then, and the main shaft of dial drives disk and rotates in order; All aim at the pin plate of unblanking of bolt-operating mechanism when the breach of some disks; The pin plate of unblanking moves down the entering breach, has then removed the restriction of splitting bolt mechanism, and bolt-operating mechanism is taken advantage of a situation bolt is opened.
Chinese patent 02135963.6 has been introduced a kind of mechanical thumbwheel puzzle lock, comprises multi-disc ring-type combination disk, chassis, lock bolt, bolt-operating mechanism, detent mechanism, shell and dial, also comprises dial-up mechanism, resetting-mechanism and spy ink recorder structure.Dial-up mechanism comprises structural frame, dial-up piece, control device.Control device includes sleeve, ratchet, control panel.Structural frame is a cylindrical shape; Structural frame is fixedly connected with the main shaft of outside unlocking handle through connecting axle; On the cylinder of structural frame, have the groove of placing the dial-up piece, the dial-up piece is a sheet, is contained in the groove of structural frame; Be provided with spring in the structural frame groove of dial-up piece tail end, the cephalic par of dial-up piece can pop up under the effect of spring.Sleeve can be enclosed within outside the structural frame cylinder with relatively rotating; Sleeve surface along the circumferential direction has slotted eye; This slotted eye can supply dial-up build end to come in and go out, and under the effect of spring, the cephalic par of dial-up piece can pop up slotted eye; Under the compressing of sleeve, the cephalic par of dial-up piece can also be withdrawn in the groove.On the end face of sleeve near control panel one side, be provided with ratchet, be provided with ratchet in the position of relative ratchet, the outer rim of control panel is a cam-like, and the cam at the edge of the controlled dish of ratchet is controlled and matched with ratchet.
This invention is a kind ofly existing disc type mechanical code lock to be driven the mode that combination disk rotates on the know-why innovation has fundamentally been arranged; But wherein dial-up mechanism is as a vitals of coded lock; Because in its structure design its irrationality is arranged, manufacture craft is relative complex also.Can know from the structure of the dial-up mechanism of this patent; Its essence is and processing some grooves on the cylindrical circumference with on the direction of axis normal; The position of respective grooves processes two axial pin shaft holes from the cylindrical end face again, and these two pin shaft holes are used for the dial-up piece is positioned with spacing.Dial-up piece and spring are put into groove, and alignment pin is passed the shaft hole of each dial-up piece successively from the alignment pin axis hole, and then penetrates the highest ejected position of each dial-up piece of spacer pin axis limit, at last sleeve is installed on the cylinder.Under the effect of outdoors unlocking handle; Structural frame and sleeve relatively rotate or are static; The cam control of the controlled plate edge of ratchet cooperates with ratchet, and control dial-up piece ejects the groove from sleeve under spring action in order, and the dial-up piece of ejection cooperates with the combination disk of the ring-type that is positioned at its outer rim; The breach of some combination disk is all aimed at the pin plate of unblanking of bolt-operating mechanism, can operate bolt-operating mechanism and open the door.
At first; The technology of processing groove and pin shaft hole is very complicated on this columned structural frame; And exigent precision, yield rate is lower, the also corresponding raising of cost; Also limited coded lock virtually for the popularizing of average family, therefore needed the processing method that a kind of technology is simple, manufacturing cost is low or design another kind of form of structure.
Secondly; The dial-up piece is under the effect of spring, to eject sleeve, and the collision of dial-up piece and spacing bearing pin produces impact force in ejection process, and the position that dial-up piece and spacing bearing pin contact with each other is a bit of straight line; Distortion appears in this contact line segment easily, causes the dial-up piece to be stuck.And coded lock is as the operating mechanism of a precision; The gap of groove on the cylinder and dial-up piece is very little; And the dial-up piece also need be corresponding with the combination disk that is positioned at its outer rim, and this all needs very accurate cooperation, and the work that distortion will influence lock core dial-up mechanism normal reliable appears in the dial-up piece.
Moreover the spring that is placed in the cylinder groove of upspringing of dial-up piece is controlled, and the application life of the spring that multi-form or different processing technologys are made is different, and the functional reliability of lock core dial-up mechanism is had fundamental influence.Spirality compression spring is not suitable for miniaturization lock core dial-up mechanism and uses, though adopt torsion spring can realize the upspringing function of dial-up piece, limited owing to the in-house space of lock core dial-up, it is very little that torsion spring can only be done, and fatigue break takes place easily.In case the spring fatigue phenomenon that fractures occurring is exactly major accident.
In addition, the inner combination disk of each dial-up piece and lock core is a position relation one to one, and structural frame is to be fixedly connected with the main shaft of unlocking handle, and connecting axle is that securing elongated and main shaft as structural frame is connected.When dial received very little strength impact in the lock body outside, main shaft will promote structural frame and produce axial displacement, causes the dial-up piece that corresponding axially-movable takes place, and the dial-up piece just can not be corresponding one by one with combination disk, and lock core dial-up mechanism can not operate as normal.Therefore the impact resistance of this patent lock core dial-up mechanism very a little less than.
At last; The sleeve of lock core dial-up mechanism is a strength member of realizing the coded lock design function, can have multiple processing technology manufacturing technology to realize its function, considers the processing and fabricating cost; Satisfying under the prerequisite of function of use, it should be first-selected adopting processing technology thereof with low cost.
