Dab tsi yog qhov txawv ntawm cylindrical pins thiab fastener pins
Tus pin fastener feem ntau yog siv rau qhov chaw, tab sis kuj rau kev sib txuas, thiab nws yog tsau rau hauv tus pin qhov los ntawm kev cuam tshuam haum. Fastener pins siv rau kev tso npe feem ntau tsis raug thauj lossis thauj khoom me me, tus lej tsis tsawg dua ob, muab faib rau hauv cov kev taw qhia symmetrical ntawm tag nrho cov qauv ntawm cov khoom sib txuas, qhov deb ntawm qhov zoo dua, cov pins txuas nrog txhua qhov kev sib txuas. . Qhov ntev hauv daim yog li 1 mus rau 2 npaug ntawm txoj kab uas hla me me.
Kev kam rau siab precision yuav tsum tau rau tus pin fastener yog qhov siab, txwv tsis pub tus pin yuav yooj yim poob yog tias qhov haum tsis zoo. Qhov zoo ntawm tus pin fastener yog tias lub zog zoo dua.
Raws li lub npe implies, tus pin elastic yog ib tug elastic pin, nrog ib tug hollow center thiab ib tug qhib sab, uas yog yooj yim rau kev sib dhos, vim hais tias tus pin muaj shrinkage, thiab cov tshuaj tiv thaiv quab yuam tom qab shrinkage yuav ua rau tus pin haum nruj nreem nrog lub puab qhov. . Yog tias lub qhov yog 3. 3.15-3.25 (tsim rau lub cev yas); 3.3-3.5 ( haum rau lub cev hlau).
