Qib xauv - txhim khu kev qha kev tiv thaiv ntawm koj lub tsev

Qib xauv - txaus ancient invention. Nws zaj dab neeg pib rov qab nyob rau hauv lub xyoo pua puv 19, thaum lub English inventor Yelemi Chubb patented lub thiaj li hu ua "ntes". Ib tug feature tshwj xeeb ntawm no complex mechanism yog tias thaum uas siv lub xauv yog txiav sim los ntawm cov tsis ncaj ncees lawm qhov tseem ceeb. Criminals yog khaws cia los ntawm re-nyiag nkas, thiab tus tswv tsev, yog li ceeb toom ntawm sim nkag mus. Thaiv cov hlab tau tshem tawm nrog ib tug tshwj xeeb tseem ceeb, uas yog muag nrog qib locks.

Nyob rau hauv 1824, Tij Laug Charles Chubb ho paub mechanism thiab qib xauv nws los ua tau siv tsis muaj ib tug yuam sij thib ob. Tsis ntev, ua tsaug rau haum kev vam meej tsim mechanism tau yeej zoo kawg muaj koob meej ntawm tau txais kev pab.

Rau hnub tim, lub xauv qib yog tsis npaj rau xauv qhov system thaum ua tau txwv tsis pub siv. Qhov no yooj yim sib txawv los ntawm nws cov thawj ntawm.

Nyob rau hauv dav dav, lub mechanism yog ib tug txheej ntawm tshwj xeeb daim hlau (levers) nyob rau ua tshwj xeeb grooves (notches) ntawm ib tug loj thiab zoo. Lawv muaj kev cob cog rau lub txais tos - ib tug tseem ceeb heev ib feem ntawm lub ntsia liaj qhov rooj. By xa cov tseem ceeb, txhua lub levers yog tsa rau ib tug ntev ntawm ib qhov chaw rau nws. Lub xauv qhib tsuas yog thaum tag nrho cov daim hlau yuav nyob rau hauv lawv cov txaus qhia, freeing li ib tug slot rau cov dawb tso cai ntawm lub ntsia liaj qhov rooj. Txawm li cas los, Yog hais tias tsawg kawg yog ib tug ntawm cov levers tsis coj kom zoo txoj hauj lwm, ces sawv ntsia liaj qhov rooj thaum txoj siav tus yuam sij yuav tsis txav.

Thaum xaiv ib tug mechanism them nyiaj tshwj xeeb mloog mus rau lub fact tias ib tug txhim khu kev qha zoo theem xauv - yog:

• tsis tsawg tshaj li rau levers;
• Class III kuj mus stripping thiab saum toj no;
• armor phaj thiab bronenakladki li ib tug ntxiv tiv thaiv tawm tsam drilling;
• tam beams uas tiv thaiv tiv thaiv sawing;
• ntxiv tsis pub leejtwg paub hais tias tiv thaiv xauv kim: tsis mechanisms thiab cuav notches;
• precision tuav nrog beards ua tib zoo polished thiab nruj txoj cai ces kaum;
• tau transcoding siv cov cartridge ntawm levers los yog tej poob lawm ntawm lub lag luam.

Ib tug tseem ceeb drawback ntawm tus txheej txheem qib tsim - qhov yuav tsum tau rau tag nrho kev hloov ntawm lub xauv nrog ib tug poob qhov tseem ceeb. Txawm li cas los, niaj hnub manufacturers tau coped nrog qhov teeb meem no. Nyob rau hauv kev ua lag luam niaj hnub no koj yuav nrhiav tau ib tug pas xauv nrog tau hloov daim card mechanism ntawm ib tug tshiab tso, los yog ib tug xov tooj unlimited kev hloov dua siab tshiab. Ntxiv mus, cov nta no tsis muaj rau tsis tau tso cai cov neeg, txij li thaum lawv yuav tsuas yuav khiav nyob rau hauv ib qho qhib lub xeev ntawm lub xauv.

Yuav ua li cas mus qhib ib tug xauv qib? Nws tsim yuav ib tug loj yaum sij, los ntawm kev uas attackers yuav tau sim siv ib tug passkey. Tab sis tos ib tug xauv, ces nws yog suab tsis yooj yim sua. Yog li ntawd, feem ntau cov crackers puas ntsia liaj qhov rooj siv ib tug xyaum, xa cov teeb meem kom nws. Yog hais tias ua kom raug, qhib lub mechanism yuav tsis tau yooj yim. Txawm li cas los, cov kev puas tsuaj ntawm qhov tseem ceeb-khib - ib tug heev me teeb meem, uas cov attackers kawm tshwj xeeb. Tshwj xeeb schemes, uas yog kom meej meej qhia los ntawm txoj cai taw tes ntawm lub tsev fuabtais, lawv thov mus rau lub qhov rooj, aligning nrog lub xauv, thiab drilled qhov twg tsim nyog.

Lwm txoj kev qhib no hom ntawm xauv - ntxig rau hauv lub qhov mus rau Mount tus yuam sij los yog zoo li tus kwv, uas los ntawm nws loj yuav tshaj tus yuam sij. Yog li, lub qhov yuav nthuav thiab nws yuav tau mus nkag rau svertysha. Xa nws los ntawm kev siv ib tug ciaj ntswj, koj yuav xyuas kom meej tias svertysha presses lub zuag hniav, thiab levers li tsis sawv. Tej yam kev quab yuam yuav tsiv mus nyob rau lub upright thiab tsoo nws, yuav ua lub xauv opens. Txawm li cas los, nyob rau hauv cov ntaub ntawv no, nws yuav tau siv ib tug ntau ntawm kev rau siab.

By txhim kho qib xauv, nco ntsoov tias txawm lub feem ntau kim thiab txhim khu kev qha mechanism tsis muab ib tug meej guarantee los ntawm qhib koj qhov rooj. Yog li ntawd, nyob rau hauv kom tsis txhob ntes zoo siv cov xauv qhov rooj ntawm ob ntau hom kev.
