Cov hau fwj tsis yog tsuas yog thawj kab ntawm kev tiv thaiv los tiv thaiv cov ntsiab lus, tab sis kuj yog qhov txuas tseem ceeb hauv kev paub ntawm cov neeg siv khoom, thiab yog tus nqa khoom tseem ceeb ntawm lub npe lag luam thiab kev paub txog cov khoom. Raws li ib hom koob fwj fwj, cov hau flip yog cov qauv fwj fwj nrov heev thiab yooj yim siv, tus yam ntxwv los ntawm lub hau txuas nrog lub hauv paus los ntawm ib lossis ntau lub pob khawm, uas tuaj yeem yooj yim "flipped qhib" kom pom qhov hluav taws xob, thiab tom qab ntawd "snapped" kom kaw.
Ⅰ, Txoj cai siv tshuab nqa
Lub hauv paus ntsiab lus tseem ceeb ntawm lub hau npog yog nyob rau hauv nws cov qauv pob khawm thiab lub tshuab xauv / kaw:
1. Cov qauv pob khawm:
Kev Ua Haujlwm: Muab ib lub axis tig raulub hauqhib thiab kaw, thiab tiv taus kev ntxhov siab ntawm kev qhib thiab kaw ntau zaus.
Hom:
●Lub Pob Khawm Nyob:Hom uas siv ntau tshaj plaws. Siv qhov yooj ywm ntawm cov yas nws tus kheej (feem ntau yog siv cov khoom siv PP), ib daim kab txuas nyias thiab nqaim tau tsim ntawm lub hau thiab lub hauv paus. Thaum qhib thiab kaw, daim kab txuas raug hloov pauv elastic bending deformation es tsis tawg. Qhov zoo yog cov qauv yooj yim, pheej yig, thiab ib daim molding.
●Tus yuam sij kev txawj ntse:kev xaiv cov khoom siv (ua haujlwm tau zoo, PP tiv taus qaug zog), tsim lub pob khawm (tuab, dav, nkhaus), pwm raug (xyuas kom txias sib npaug kom tsis txhob muaj kev ntxhov siab sab hauv ua rau tawg).
●Lub pob khawm uas txuas rau/clip rau:Lub hau thiab lub hauv paus yog cov khoom sib cais uas txuas nrog los ntawm ib qho qauv snap-on ywj pheej. Hom pob khawm no feem ntau muaj lub neej ntev dua, tab sis muaj ntau qhov, sib dhos nyuaj, thiab tus nqi kim heev.
●Tus pin hinge:Ib yam li lub pob qhov rooj, cov hlau lossis yas siv los txuas lub hau thiab lub hauv paus. Nws tsis tshua muaj nyob rau hauv cov ntaub ntawv ntim khoom kom zoo nkauj thiab feem ntau yog siv rau hauv cov xwm txheej uas xav tau kev ruaj khov siab lossis kev tsim tshwj xeeb.
2. Lub tshuab xauv/kaw
Kev Ua Haujlwm: Xyuas kom lub hau kaw ruaj khov, tsis yooj yim qhib tsis tau, thiab ua tiav kev sib khi.
Cov txheej txheem siv ntau:
