Description

A kind of master control lock

Technical field

The utility model relates to a kind of lockset, specifically the master control lock of a kind of strongbox that is provided with electronic password lock or Fingerprint Lock, cabinet, safety door.

Background technology

Strongbox, the master control lock of cabinet and safety door, generally must authenticate by Chinese safety technological guard, Bing Jing Ministry of Public Security pattern inspection side, reach mechanical anti-theft lock GAT73-94 standard-required, its secondary lock all adopts mechanical code lock, electronic password lock or Fingerprint Lock, as the patent No. Chinese patent < < door lock > > that is CN00120708.3, by master control lock and secondary controlling lock, formed, described master control lockset has driver, , walk device, locking main body, the described device of walking has the axle of walking and a 1-5 quilt position key seat, on each key seat, there is one by position pin, locking main body has the pin of walking and a 1-5 quilt position pin-and-hole, the described pin of walking can move up and down in walking hole, by position pin, can in by position pin-and-hole, be moved up and down, secondary controlling lock has passive locked body and 1-5 locked hole seat, on described locked hole seat, there is through hole.The secondary lock of this structure door lock is to adopt mechanical lock, and theftproof performance is not very high.Although and adopt electronic password lock, Fingerprint Lock greatly to increase theftproof performance, but due to the event of components and parts, must lock by configuration emergency opening, the existing Plum blossom type lock that is generally tubulose key, and its pick-proof, anti-drilling, anti-technical opening function are extremely low, therefore have high hidden danger, sternly affected the security performance of strongbox, wooden cabinet, safety door integral body.

The existing patent No. is Chinese patent < < master control lock > > of CN201220211979.3, comprise lock body, also comprise interlock pellet or a pin, be limited in movably in the stepped hole of lock core tail end, outer end at interlock pellet or pin is equipped with return spring, makes it keep inside trend; One back-up ring, is placed on the step of lock core tail end, the outer end of return spring, and back-up ring is provided with the through hole that can place for interlock pellet or pin; One emergent plectrum, is placed on back-up ring outside, and the interlock breach of planting when inner side is provided with Gong the interlock pellet corresponding with the lead to the hole site of back-up ring or pin ejection; One emergency key, promotes by its end the interlock breach that interlock pellet or pin enter emergent plectrum, realizes the unlatching of emergency mechanism.This lockset is easy to use and safe and effective, but its interlock pellet is arranged on the side of lock core, is to rely on the varied in thickness of key and move, and this is just high to required precision, bad control.On market, traditional lockset is all comprised of overcoat, lock body and lock core in addition, and therefore complicated structure also needs further improvement.

Summary of the invention

Technical problem to be solved in the utility model is that a kind of rational in infrastructure, convenient manufacture and the lock of master control is safely and effectively provided for the above-mentioned state of the art.

The utility model solves the problems of the technologies described above adopted technical scheme: a kind of master control lock, comprise lock core shell, lock core, master key and emergency key, in lock core, be provided with different differential blade or pellets, the afterbody of lock core is provided with interlock pellet or pin, it is characterized in that: the afterbody upside of described lock core runs through to offer for interlock pellet or pin and inserts and spacing hole movable up and down, in the outer end of interlock pellet or pin, be equipped with and can make it keep the back-moving spring of inside trend, the position of interlock pellet or pin is corresponding with the position of the one side of the tooth on emergency key width, tail end at lock core is arranged with an emergent driving lever, the interlock breach of planting when the inner side of emergent driving lever is provided with for interlock pellet or pin ejection, described emergency key has the grooved identical with master key, tartar and differential, in the end of emergency key, be provided with for promote to link pellet or pin and enter the lengthening part that the interlock breach of emergent driving lever is opened emergency mechanism.

As improvement, the tail end of described lock core forms the step of undergauge, described spacing hole is opened in the upside of step, in spacing hole, be provided with for move son or pin of distich and carry out spacing stopper slot, described interlock pellet or pin are provided with corresponding limited block, outward opening place at spacing hole is provided with a block, described back-moving spring is placed on the outer end of interlock pellet or pin, one end and limited block offset, the inner side of the other end and block offsets fixing, and make to link pellet or pin have the trend that inwardly stretches into all the time lockhole.

As improvement, one end of described emergent driving lever is cirque structure, this cirque structure is nested with on the step of lock core tail end and offsets with the rear end face of lock core shell, described interlock breach is arranged on the circular hole inner side of cirque structure, on cirque structure, be provided with an arcuate socket, between arcuate socket and the rear end face of lock core shell, be provided with alignment pin; The other end of described emergent plectrum is connected with the opening mechanism of electronic password lock or system of fingerprints.

As improvement, the front end of described lock core is provided with an anti-drilling sheet, and the diameter of described anti-drilling sheet is greater than lock core diameter, is provided with the perforate corresponding with the lockhole of lock core on anti-drilling sheet.

Improve again, the lock core hole front end of described lock core shell is provided with the cannelure of the indent embedding for anti-drilling sheet, on the inwall of cannelure, be provided with a jump-ring slot, the outer peripheral face of anti-drilling sheet is provided with the annular groove corresponding with jump-ring slot, and a jump ring is arranged between jump-ring slot and annular groove anti-drilling sheet is fixed.

Further improve, the inner end of described interlock pellet or pin is is convenient to the conical surface that emergency key inserts rear promotion.

Compared with prior art, the utility model has the advantage of: changed the structure that traditional lockset is comprised of overcoat, lock body and lock core, lock core is directly assemblied in lock core shell, made structure greatly simple; Link pellet or pin are arranged on to the upside of lock core, width by emergency key just changes and moves, make emergency key ratio be easier to produce and control, in the time of need to opening, as long as emergency key is inserted in lock core, the interlock breach that promotes interlock pellet or the emergent driving lever of pin insertion just can conveniently be opened; At lock core, be provided with anti-drilling sheet outward in addition, greatly increased anti-drilling, the tamper-resistant function of lock body.The utility model is simple in structure, reasonable in design, assembling quick, easy to use and safe and effective, has anti-drilling, pick-proof, protecting against shock function preferably, applicable to strongbox case, cabinet or the safety door with electronic password lock, system of fingerprints.
