Izikrufu ezincinci zidibene nobomi bethu. Abanye banokukhanyela, kodwa sisebenzisa izinto ezinezikrufu mihla le. Ukusuka kwizikrufu ezincinci kwii-smartphones ukuya kwiziqhoboshi kwinqwelomoya nakwiinqanawa, siyakonwabela ukukhululeka okuziswa zizikrufu ngalo lonke ixesha. Ke, kuyafuneka ukuba siqonde i-ins kunye nokuphuma kophuhliso lwe-screw.
- Imvelaphi yoqobo
Izikrufu ziyimveliso yoluntu lwezoshishino. Kunzima ukukhangela ukuveliswa kwesikrufu sokuqala namhlanje, kodwa ubuncinci kwinkulungwane ye-15 yaseYurophu, izikrufu zentsimbi zazisetyenziswa njengeziqhoboshi. Nangona kunjalo, phantsi kweemeko ngelo xesha, inkqubo yokuvelisa izikrufu yayinzima kakhulu kwaye ixabiso laliphezulu, ngoko ke izikrufu zazinqabile kwaye zingasetyenziswanga kakhulu.
- Inkqubela enkulu
Ekupheleni kwenkulungwane ye-18, kwenziwa inkqubela enkulu ekuvelisweni nasekusetyenzisweni kwezikrufu. Ngomnyaka we-1770, umenzi wesixhobo u-Jesse Ramsden wenza i-lathe yokuqala yokusika i-screw, eyaphefumlela ukuveliswa komatshini we-screw. Ngo-1797, uMaudsley wenza i-all-metal precision screw lathe. Kunyaka olandelayo, uWilkinson wenza umatshini wokwenza amandongomane kunye nebholiti. Ngeli xesha, izikrufu zazidume kakhulu njengeendlela zokulungisa, kuba kufunyenwe indlela engabizi kakhulu yokuvelisa.
- Uphuhliso lwexesha elide
Ngenkulungwane ye-20, iintlobo ezahlukeneyo zeentloko ze-screw zavela. Ngo-1908, intloko yesikwere iRobertson screw yayithandwa ngenxa yeempawu zayo ezingatyibiliki ngexesha lofakelo. Ngo-1936, isikrufu sentloko sikaPhillips sayilwa kwaye sanikwa ilungelo elilodwa lomenzi wechiza, ehlala ixesha elide kwaye iqinile kunesikrufu sikaRobertson.
Emva kwekhulu lama-21, iintlobo ze-screws zihluke kakhulu kwaye izicelo zihlanjululwa ngakumbi. Iimeko ezahlukeneyo zokusetyenziswa, njengezindlu, iimoto, iibhulorho, njl. njl., kunye nezixhobo ezahlukeneyo ezifana nentsimbi, umthi, ibhodi yegypsum, njl., ziya kusebenzisa izikrufu ezahlukeneyo. Inkqubo yonyango lobushushu kunye nonyango lwe-screws luhlala luphucula rhoqo.
Ukuba ufuna izikrufu okanye iziqhoboshi ezilungiselelwe wena, sinayo le nto uyikhangelayo. I-Tianjin Lituo Hardware ineminyaka engama-20 yamava kwimveliso ekhawulezayo kunye neentengiso, kwaye siya kukubonelela ngenkonzo eyanelisayo.
