Abstract

The utility model discloses an anti-theft dial code lock which comprises a lock body, a dial disk, and an unlocking and locking mechanism. The lock is composed of a locking shaft, an encoding casing pipe, a dialing shaft, a switch button, etc. Because the utility model uses a multi-dialing disk rotary locking mechanism with the structure of convex strip shafts and concave groove disks, the lock has the advantages of simple structure, small size, large code capacity, difficult induction the position of unlocking codes, and good anti-theft and anti-prizing performance.

Description

The dial-type puzzle theft-proof lock

The utility model relates to a kind of mechanical code lock, and the coded lock of a plurality of dial structures is especially arranged.

At present, the dial-type mechanical code anti-theft lock that uses in the society mostly has complex structure, number of password is few, changes the sign indicating number difficulty, uses inconvenience, and defectives such as theftproof performance difference often can not be used separately.

The purpose of this utility model provide a kind of simple in structure, number of password big, adapt sign indicating number and dial-type coded lock technology easy to use, that theftproof performance is good.

The utility model is achieved in that a kind of dial puzzle theft-proof lock, comprises tapered end, dial and lockset switching mechanism.Tapered end is by the lock shaft 10 that is contained between tapered end fixed head 9 and 12, coding sleeve pipe 6,7,8, shifting shaft 2 and release knob 1 composition such as grade that is attached thereto.One end of shifting shaft has a groove and an axial jump ring groove of placing jump ring 4 of placing driver blade 3, shifting shaft is installed on the tapered end fixed head 9 by jump ring and removable insole pieces, place the shifting shaft in the tapered end fixed head to be connected with release knob, the fluted disc engagement on fluted disc and the lock shaft is arranged on the shifting shaft and make it rotation with an internal thread.Place the pipe end of each coding sleeve pipe in the fixed head that one disk is all arranged, all have two and half garden grooves on its outer rim, each sleeve pipe of encoding overlaps successively and is through on the release knob that is loaded on the shifting shaft in the tapered end fixed head and is attached thereto, the other end of each sleeve pipe is provided with the teeth corresponding with dial endoporus teeth groove and is socketed on respectively in the perforation, and the coding sleeve pipe is rotated by the calibration lattice.The disk that the lock shaft cylindrical is close to the sleeve pipe of encoding is arranged in parallel with the coding sleeve pipe, also is provided with a long semicircle type raised line on the outer garden of axle vertically, constitutes many dial rotary locking mechanism of band raised line axle and groove dish structure.During the rotating switch button, can make the disk tangent rotation of lock shaft by the fluted disc of shifting shaft along each coding sleeve pipe, when forwarding to the outer garden dish of the sleeve pipe of encoding, the raised line on the lock shaft can't be rotated further again when contacting, at this moment, release knob is limited to rotate counterclockwise, switch arrow points locking (initially) position of release knob, lockset is in locking states.Has only the correct unlocking cipher of input, promptly rotating dial respectively makes the half garden groove of coding on the sleeve pipe forward certain to fix (unblanking) aligned in position, and when corresponding with half garden raised line on the lock shaft, the semicircle raised line of lock shaft can embedded coding sleeve pipe disk half garden groove rotate, coding sleeve pipe garden dish is disengaged the restriction of lock shaft rotation, release knob and shifting shaft can rotate counterclockwise, and drive lockset by the driver blade on the shifting shaft and realize opening and closing latching operation.

Be carved with scale and numeral on the outside anchor ring of each dial, have and the corresponding teeth groove of sleeve pipe pipe end teeth of encoding at the endoporus of dial, each dial is sleeved on successively on the teeth of coding sleeve pipe and by release knob and is fixed.Under unlocking condition, make in the groove of raised line embedded coding sleeve pipe disk of lock shaft, extract removable insole pieces 5 out, make release knob and coding sleeve pipe produce axial motion, just can respectively dial and coding sleeve pipe be separated, by adjusting the meshing angle of each dial and coding sleeve pipe, recover the coding sleeve pipe after promptly dial being turned over corresponding number, then removable insole pieces is turned back to original position, adapt password fast thereby finish, at this moment, the number combination that aligns the release knob arrow on each dial is the new password of this lock.Screw 11 is fastening and be fixed on the door-plate with other mechanisms of tapered end and lockset, destroys from dismantling and be difficult to outdoors.

Adopt technique scheme, ideally realized the purpose of its invention.Compare with existing dial puzzle theft-proof lock,, make tapered end simple in structure owing to adopted many dial rotary locking mechanism of band raised line axle and groove dish structure, volume is little, do not need left-handed right-hand rotation coding, do not have specific sound and sensation during dial-up, position that can't the sensing unlock code.Password is made up of long number, is easy to memory and use, dial number and number scale division value can be set on demand determine number of password, the pin design amount can be selected between 100,000～several hundred million groups, number of password is very big, and confidentiality and anti-pirate of the open performance are good, and replaceable multiple mechanical lock is made coded lock.In addition, adopt the inside and outside two sides of door to grip mounting structure, shock resistance, the anti-pick-proof of pounding is even destruction dial and release knob still can't be unblanked to sign indicating number.

The utility model is described in further detail below in conjunction with drawings and Examples:

Figure one is the structure cut-away view of dial-type puzzle theft-proof lock

Figure two is A-A sectional views of tapered end lockset position of coupler

Figure three is that the B of dial-type puzzle theft-proof lock is to view.

1. release knobs, 2. shifting shafts, 3. driver blades, 4. jump rings, 5. removable insole pieces 6,7 among the figure, 8. coding sleeve pipe 9,12. fixed heads 10. lock shaft 11. hold-down screws 13,14,15. dial.

Outer the holding of present embodiment release knob is carved with arrow on the button, inner for having axial cross recessed wire connection head.By jump ring removable insole pieces and driver blade are fixed on the tapered end shifting shaft.Driver blade is fixed in the groove of shifting shaft, the one end drives the lockset switching mechanism and finishes the action of switching lock, the other end stretches in the release knob wire connection cross recess, the thread connection of lockable shifting shaft and release knob, by adjusting the connecting thread length of release knob and shifting shaft, the length that can adjust tapered end is to adapt to the thickness of different door-plates during the peace lock.Respectively be provided with two semicircle grooves on the coding sleeve pipe disk, can make lock shaft rotate two circles, so that finish specific switching lock action.Angle between two grooves is relevant with the size of lock shaft and coding sleeve pipe disk.The password of present embodiment determines that by 3 dial and the number number of divisions number scale division value is 60 on the dish, and password is counted N=60 ³=21.6 ten thousand groups, make us being difficult to crack.
