Chitayi Chachingwe

Taye ya chingwe (yomwe imadziwikanso kuti hose tie, zip tie) ndi mtundu wa chomangira, cholumikizira zinthu pamodzi, makamaka zingwe zamagetsi, ndi mawaya. Chifukwa cha mtengo wake wotsika, kugwiritsa ntchito mosavuta, ndi mphamvu zomangirira, zomangira zingwe zimakhala paliponse, kupeza kugwiritsidwa ntchito muzinthu zina zambiri.

Tayi wamba wamba, yomwe nthawi zambiri imapangidwa ndi nayiloni, imakhala ndi gawo la tepi losinthika lomwe lili ndi mano omwe amalumikizana ndi pawl pamutu kuti apange ratchet kotero kuti kumapeto kwaulele kwa gawo la tepi kumakokedwa chingwecho chimalimba ndipo sichidzasinthidwa. . Zomangira zina zimaphatikizapo tabu yomwe ingathe kukhumudwa kuti imasule ratchet kuti tayi ikhoza kumasulidwa kapena kuchotsedwa, ndipo mwinamwake kugwiritsidwanso ntchito. Zomasulira zazitsulo zosapanga dzimbiri, zina zokutidwa ndi pulasitiki yolimba, zimathandizira ntchito zakunja komanso malo owopsa.

Kupanga ndi kugwiritsa ntchito

Chingwe chodziwika bwino kwambiri chimakhala ndi tepi yosinthika ya nayiloni yokhala ndi zida zophatikizika, ndipo mbali imodzi imakhala ndi kachikwama kakang'ono kotseguka. Pamene nsonga yolunjika ya tayi ya chingwe imakokedwa pamlanduwo ndikudutsa pa ratchet, imalepheretsedwa kubwezeredwa; lupu lotulukalo likhoza kukokedwa mwamphamvu. Izi zimathandiza kuti zingwe zingapo zimangiridwe pamodzi kukhala mtolo wa chingwe ndi/kapena kupanga mtengo wa chingwe.

Chida chomangirira chingwe kapena chida chingagwiritsidwe ntchito kuyika tayi ya chingwe yomwe ili ndi mphamvu inayake. Chidacho chikhoza kudula mchira wowonjezera ndi mutu kuti upewe m'mphepete mwake womwe ungayambitse kuvulala. Zida zopangira kuwala zimagwiritsidwa ntchito pofinya chogwirizira ndi zala, pomwe matembenuzidwe olemetsa amatha kuyendetsedwa ndi mpweya woponderezedwa kapena solenoid, kuteteza kuvulala kobwerezabwereza.

Pofuna kukulitsa kukana kwa kuwala kwa ultraviolet pa ntchito zakunja, nayiloni yokhala ndi 2% yakuda yakuda imagwiritsidwa ntchito kuteteza maunyolo a polima ndikukulitsa moyo wautumiki wa tayi ya chingwe. ali ndi zowonjezera zitsulo kuti athe kuzindikiridwa ndi zowunikira zitsulo zamakampani

Zomangira zachitsulo zosapanga dzimbiri ziliponso kuti musapse ndi moto—zomanga zokutira zosapanga dzimbiri zilipo kuti ziteteze kuukira kwa zitsulo zofananira (monga thireyi ya zinki).

Mbiri

Zomangira zama chingwe zidapangidwa koyamba ndi Thomas & Betts, kampani yamagetsi, mu 1958 pansi pa dzina la Ty-Rap. Poyamba, zidapangidwa kuti zizipanga ma waya a ndege. Mapangidwe oyambirira anagwiritsira ntchito dzino lachitsulo, ndipo awa angapezekebe. Opanga pambuyo pake adasintha kukhala kapangidwe ka nayiloni/pulasitiki.

Kwa zaka zambiri mapangidwewo adakulitsidwa ndikupangidwa kukhala zinthu zambiri zozungulira. Chitsanzo chimodzi chinali chodzitsekera chodzitsekera chomwe chinapangidwa ngati njira yosinthira chikwama cha purse-string mu colon anastomosis.

Wopanga ma chingwe a Ty-Rap, Maurus C. Logan, adagwira ntchito kwa Thomas & Betts ndipo adamaliza ntchito yake ndi kampaniyo monga Wachiwiri kwa Purezidenti wa Research and Development. Panthawi yomwe anali ku Thomas & Betts, adathandizira pakupanga ndi kutsatsa kwazinthu zambiri zopambana za Thomas & Betts. Logan anamwalira pa 12 November 2007, ali ndi zaka 86.

Lingaliro la tayi ya chingwe linabwera kwa Logan pamene akuyendera malo opangira ndege za Boeing mu 1956. Mawaya a ndege anali ovuta komanso atsatanetsatane, okhudzana ndi mawaya zikwi zambiri opangidwa pa mapepala a plywood a 50-foot-waatali ndipo amagwiridwa ndi mfundo. , chingwe cha nayiloni chokulungidwa phula. Fundo iliyonse inkafunika kukokedwa mwamphamvu pomangirira chingwe chala chake chomwe nthawi zina chimadula zala za wogwiritsa ntchitoyo mpaka atapanga ma calluses okhuthala kapena "manja a hamburger." Logan anali wotsimikiza kuti payenera kukhala njira yosavuta, yokhululuka, yochitira ntchito yovutayi.

Kwa zaka zingapo zotsatira, Logan anayesa zida ndi zida zosiyanasiyana. Pa June 24, 1958, chilolezo cha chingwe cha Ty-Rap chinatumizidwa.
