Description

Binary channels coded lock

Technical field

The utility model is related to binary channels coded lock, in particular for being easy to the double of customs's safety inspection unlatching on case and bag Passage coded lock.

Background technology

Because latch hook can be separately turned on lock by coded lock and key lock in binary channels coded lock, for lock class reliability Property for, more complicated structural reliability can be lower, easily break down probability it is bigger, while produce install also can be more tired Difficulty, the structure of two lock set groups of existing binary channels coded lock is more complicated, and the transmission with locking is especially being opened with moveable lock hook In mechanism, generally require to go to complete more complicated transmission compared with multi-part to realize, whichever part occurs getting stuck or damages Badly will result in whole lock body cannot use, therefore all there is the defect that reliability is low and installation is complicated.

The content of the invention

The utility model for existing binary channels coded lock exist deficiency, there is provided a kind of simple structure, transmission can By, binary channels coded lock easy for installation.

In order to solve the above technical problems, the utility model uses following technical scheme：A kind of binary channels coded lock, including shell Body, housing is provided with coded lock group, key lock group, and shift knob, latch hook and lock, coded lock group include character wheel, cam, locking bar With adjust code switch, key lock group includes key cylinder, and shift knob is engaged with locking bar, and the latch hook is rotatably hinged on housing On, latch hook is connected with reply torsion spring, and the reply torsion spring provides latch hook and is returned to the restoring force coordinated with lock locking, latch hook one End is provided with push and block bar, and the other end is provided with pressure pin, and the key cylinder lower end is provided with oblique table top, and the oblique table top is from lower end Minimum point rotates rising transition to upper end peak along the rotation round direction of key cylinder, and the push and block bar matches with locking bar Close, and moved left and right and band moveable lock hook or so upset with locking bar, the pressure pin is engaged with oblique table top, and with oblique table top Rotate the cooperation and band moveable lock hook or so upset that pin is come and gone and pressed from minimum point to peak.

The utility model is provided the benefit that：When coded lock group is in opening, pull switch button drives Locking bar moves right, and locking bar is promoted the push and block bar on latch hook, directly causes that latch hook upset is disengaged and coordinates with the locking of lock, real Existing password is opened；When coded lock group is in lockup state, locking bar is locked out, it is impossible to is switched on and off button promotion, realizes coded lock Only, key lock group now is opened with key, and rotates key cylinder, make the oblique table top of key cylinder lower end by upper end peak With latch hook pressure pin cooperation, turn to lower end minimum point with pressure pin coordinate, during this, pressure pin by oblique table top to Under press, directly cause that latch hook upset is disengaged and coordinate with the locking of lock, realize key operated, upper end highest is rotated back into again With latch hook when pressing the cooperation of pin, latch hook is returned to lockup state to point in the presence of torsion spring is replied, only when coded lock group All it is coded lock in the opening process of both opening ways or key lock group is again turned on that latch hook could be flipped open The locking bar of group or the key cylinder of key lock group are directly driven with latch hook and coordinate, and participate in being driven without any other part, Therefore, the utility model provide binary channels coded lock have simple structure, reliable transmission, it is easy for installation the characteristics of.

Further, the tune code switch of the coded lock group includes adjusting code button and rotating push rod, on the tune code button Extruding inclined-plane is provided with, the rotating push rod lower end is hinged on housing, the side of rotating push rod upper end is engaged with extruding inclined-plane, The opposite side and cam engagement of rotating push rod upper end.

Above-mentioned improved beneficial effect is：As the tune code switch of coded lock group indispensability, in traditional structure typically all It is to promote to realize changing password along the axial direction of coded lock group, and some will adjust code to open by the way of compound mitre The structure promoted along the axial direction perpendicular to coded lock group is closed, phenomenon that inclined-plane self-locking blocks easily occurs, it is necessary to larger Reverse reverting removes the return for realizing adjusting code switch, generally requires relatively reliable returning spring and goes to realize, and skill of the present utility model In art scheme, rotating push rod is pressed down against by adjusting the extruding inclined-plane on code button, rotating push rod is overturn around pin joint, so that Realize pushing open on cam depart from the cooperation of character wheel, be rotated further by character wheel and realize adjusting code, it is this rotation is pushed to by an inclined-plane to push away The structure of bar upset would not cause larger inclined-plane self-lock force, adjust code more laborsaving, reply also more laborsaving.

Further, the extruding inclined-plane for adjusting code button is topmost connected with back slope and extruding inclined-plane forms point Portion, the rotating push rod upper end is arcwall face, and the side of rotating push rod is provided with " V " type groove, and the groove matches with tip Close, it is " door " shape structure to adjust code button, adjusts code button to be provided with crossbeam, and the locking bar is provided with lift slope, the lifting inclined Face is engaged with crossbeam lower surface.

Above-mentioned improved beneficial effect is：Promoting tune code button makes tip and fit depressions, now " V " type groove upper half The back slope that partial inclined-plane is topmost connected with extruding inclined-plane is engaged, and forms inclined-plane self-locking, makes tune code button and rotation Turn push rod to be both secured to adjust code state, it is possible to achieve one hand adjusts code, traditional tune code mode is required for a hand always according to tune Code button, another hand goes rotation character wheel to realize adjusting code, while it also avoid during code is adjusted, it is not known that individual which is rotated During character wheel, tune code button is accidentally unclamped, so as to cause the phenomenon of password loss, in the technical solution of the utility model, The operation error of tune code button is unclamped during tune code in the absence of imprudence, but has been needed after the completion of tune code, promoted locking bar A coded lock is opened, during coded lock is opened, lift slope and the cooperation for adjusting the crossbeam on code button on locking bar Tune code button can be driven to move up, so that adjust the tip on code button also to depart from the cooperation with the groove on rotating push rod, Realize adjusting the return of code button, the password of coded lock group is the accurate password of determination in the process, will not be grasped because of error Make and cause password loss.

A kind of plastic packaging machine that the utility model is provided is further described in detail with reference to the accompanying drawings and examples.
