Abstract

The utility model relates to a numeral keyless safety lock which is mainly composed of a handle, a push rod, a pull rod, a numeral disk, a housing, a gear, a ratchet wheel, a gap wheel, a shifting rack and a pusher dog thereof, a shaft sleeve, a shifting sleeve, a shaft, a spring, a lock bolt, a bracket, a check hook, etc., wherein, a wheel spoke of the gap wheel is provided with an axial pin which is inserted in a directional hole of a wheel spoke of the ratchet wheel, and the gap wheel and the ratchet wheel form a dialing wheel assembly. Different gaps are arranged at the circumferential edges of the gap wheel, so the different opening numbers of each lock are formed. When the numbers are correctly dialed, the axial pin of the wheel spoke of the ratchet wheel is inserted in an axial hole of the wheel spoke of the gear, so the gear can rotate so as to drive the rack-shaped lock bolt which is engaged with the gear to retract in the housing, and the lock is unlocked. The utility model has the characteristics that the utility model can be unlocked without a key, so the losing trouble of the key can be eliminated; the unlocking method is unique, so the security is high; the utility model has multiple functions, so the utility model can be used as a door lock and can also be used as a safety lock.

Description

A digital nothing spoon safety lock

The utility model relates to the combination padlock new varieties.

The existing combination padlock that is used for safety cabinet will use key simultaneously with 1 or 2, could open by a lock, if key has been lost, lock can't be opened, and this lock can not be used as door lock simultaneously.

The purpose of this utility model is to provide a kind of insurance frame lock that both can be used as, and can be used as door lock again, and the number that can open of key does not have a spoon safety lock.

With reference to accompanying drawing 1-2, the utility model adopts following manner to achieve the goal: the one, on axle (27), be set with breach wheel (14) from right to left, ratchet (13) and gear (11), the axial pin (23) that reeve ratchet (13) spoke axial hole is arranged in breach wheel (14) left side, ratchet (13) move left and right, pin (23) is all in the hole, in ratchet (13) left side the axial pin (24) that can inject axial hole on gear (11) spoke is arranged also, ratchet (13) can move left and right, turn right when advancing push rod (2) or pulling out pull bar (18), ratchet (13) is pushed to move together by axle (27) shaft shoulder, pin (24) leaves gear (11), dead bolt (25,34) under spring (30) elastic force effect, stretch out housing, it is locking state, breach wheel (14) periphery has the different breach of arranging, the openend that U-shaped is dialled frame (15) is positioned on wheel cover (16,26) on, rotate handgrip (1) or (19), all can make and dial frame (15) rotation, when clockwise rotating handgrip (1), be positioned on the pusher dog of dialling on the frame (15) (12) and just stir ratchet (13) with breach wheel (14) rotation, when non-return hook (32) gib head drops on breach and takes turns the 1st breach, handgrip (1) inhour is rotated a specific numeral, change clockwise again, non-return hook (32) gib head then drops on breach and takes turns on the 2nd breach, by that analogy, after repeated multiple times is finished, pin (24) is just to the hole on spur gear (11) spoke, spring (20) elastic force just ratchet (13) to left translation, pin enters in the hole, change hands clockwise again (1), ratchet (13) driven gear (11), make one section dead bolt (25) retraction housing that tooth bar is arranged, lock is just opened; The 2nd, after hand is decontroled handgrip, can not released outside the housing by spring (30) for making dead bolt, at ratchet (13) lower edge inversion T shape lock pin (and pushing away spring) is set and moves with ratchet, during unlatching, ratchet moves to left, and lock pin just injects a breach of dead bolt inboard; Ratchet moves to right when locking, and lock pin withdraws from breach, and dead bolt is just promoted by spring (30), and one section is stretched out outside the housing; The 3rd, when lock is opened, the number wheels of being made up of breach wheel and ratchet are repeatedly rotated toward clockwise direction, when locking, must inhour get back to original position, so return disc spring (22) is set, when locking, handgrip (1) inhour is to the limit the time, pusher dog (12) is pushed up from ratchet (13) by push rod (31), this moment, non-return hook (32) gib head also left breach wheel (14), disc spring (22) elastic force just makes the ratchet that discards obstruction, the breach wheels rotate back into original position, when return, for preventing that axial pin on the ratchet (24) is when going up axial hole to cog (11) in the patchhole, so lever type clutch plate and spring thereof are set between ratchet and gear, only when opening, dial frame (15) clutch plate is left downwards, the pin (24) on the ratchet (13) could inject the gear axial hole.

The utility model characteristics: the one, can open without key, eliminated key and lost and do not drive lock or stolen and stolen trouble and worry by the thief; The 2nd, do not have door lock strong security, the safety factor of encryption apparatus big than existing, it unblank and last locking method uniqueness unusual; Three are to use widely, both can be used for door lock, economize and can lock as safety cabinet again after abandoning interior handgrip (19) and pull bar (18).
