Me me screws yog woven rau hauv peb lub neej. Qee tus neeg yuav tsis lees paub qhov no, tab sis peb siv cov khoom nrog cov ntsia hlau hauv lawv txhua hnub. Los ntawm cov ntsia hlau me me ntawm cov xov tooj ntse mus rau fasteners ntawm lub dav hlau thiab nkoj, peb txaus siab rau qhov yooj yim ntawm screws txhua lub sijhawm. Tom qab ntawd nws yog qhov tsim nyog rau peb kom paub qhov ins thiab outs ntawm kev txhim kho ntsia hlau.
Lub hauv paus chiv keeb
Screws yog ib yam khoom ntawm kev lag luam hauv zej zog. Nws yog ib qho nyuaj rau taug qab qhov kev tsim ntawm thawj cov ntsia hlau niaj hnub no, tab sis cov ntsia hlau hlau tau siv los ua cov fasteners hauv Tebchaws Europe tsawg kawg hauv xyoo pua 15th. Tab sis nyob rau lub sijhawm ntawd, cov txheej txheem tsim cov ntsia hlau yog qhov nyuaj heev thiab kim, yog li cov ntsia hlau tsis tshua muaj thiab tsis siv dav.
Kev vam meej
Thaum kawg ntawm lub xyoo pua 18th, kev vam meej tau ua tiav hauv kev tsim thiab siv cov ntsia hlau. Xyoo 1770, tus kws tsim khoom Jesse Ramsden tau tsim thawj lub tshuab dhos ntsia hlau, uas tau tshoov siab rau kev tsim lub tshuab ntsia hlau. Nyob rau hauv 1797, Maudsley tau tsim lub tshuab tag nrho cov hlau precision ntsia hlau. Xyoo tom ntej, Wilkinson tau tsim cov txiv ntoo thiab ntsia hlau ua tshuab. Lub sijhawm no, screws tau nrov heev raws li ib txoj hauv kev kho, vim tias txoj kev pheej yig ntawm kev tsim khoom tau pom.
Kev loj hlob mus ntev
Nyob rau hauv lub xyoo pua 20th, ntau hom ntsia hlau taub hau tshwm. Nyob rau hauv 1908, lub square-headed Robertson ntsia hlau tau pom zoo rau nws cov khoom los tiv thaiv plam thaum lub sij hawm installation. Xyoo 1936, Phillips lub taub hau ntsia hlau tau tsim thiab patented. Nws tau ruaj khov thiab nruj dua li Robertson ntsia hlau.
Tom qab xyoo pua 21st, hom screws muaj ntau haiv neeg thiab daim ntawv thov zoo dua. Cov ntsia hlau sib txawv yuav siv rau cov xwm txheej sib txawv, xws li tsev, tsheb, choj, thiab lwm yam, thiab rau cov khoom sib txawv xws li hlau, ntoo, phab ntsa ntub dej, thiab lwm yam. Kev kho cua sov thiab kev kho deg ntawm cov ntsia hlau kuj tseem txhim kho.
Yog tias koj xav tau screws lossis kev cai fasteners, peb muaj qhov koj tab tom nrhiav. Fasto muaj 20 xyoo dhau los ntawm kev tsim khoom thiab muag khoom fasteners. Peb yuav muab kev pabcuam txaus siab rau koj.
