Chitsulo chopepuka ndi dongosolo laling'ono komanso lofunika kwambiri lachitsulo. Zakhala zikugwiritsidwa ntchito kwambiri m'nyumba zamafakitale, zaulimi, zamalonda, ndi ntchito. Wagwiritsidwanso ntchito powonjezera pansi, kusintha, ndi kulimbikitsa nyumba zakale, komanso m’madera opanda zipangizo zomangira komanso m’madera amene ali ndi mayendedwe ovuta. Ndondomeko yomanga yolimba komanso nyumba zosunthika komanso zochotseka zimakondedwa kwambiri ndi eni ake. Chinthu chofunika kwambiri kwa ife pomanga zitsulo zopepukazi ndi zomangira zobowolera zokha. Ndiye mumadziwa bwanji za zomangira zokha?

"Zomangira zodzibowolera" zimatchedwanso "zobowola", "zobowola", "zomangira zodzibowolera", zomwe zimatchedwanso "dovetail screws", Chingerezi: SELF DRILLING SCREWS. Miyezo yake yokhazikitsidwa ikuphatikiza mulingo wadziko lonse wa GB/T 15856.1-2002, mulingo waku Germany DIN7504N-1995, ndi mulingo waku Japan JIS B 1124-2003.

Zomangira zamtunduwu zimakhala ndi nsonga yobowola, yomwe imatchedwa nsongayo ngati kubowola. Pakusonkhanitsa, wonongayo imatha kubowola bowo lapakati palokha, ndiyeno gwiritsani ntchito gawo loyandikana nalo kuti lidzigunda lokha ndikutulutsa zomangira zofananira mu dzenje la chonyamulira. Ulusi, motero umatchedwa zomangira zodzibowolera ndi kugogoda.

Malinga ndi miyezo yokhazikitsidwa, zomangira za kubowola mchira zitha kugawidwa mu: National standard GB/T, German standard DIN, Japanese standard JIS, and international standard ISO.

Ikhozanso kugawidwa m'magulu otsatirawa malinga ndi ntchito ndi mawonekedwe:

1. Cross recessed poto mutu kudzibowola ndi pogogoda zomangira. Cross recessed pan mutu pobowola zomangira ndi kugogoda wononga ulusi Kukhazikitsa muyezo: GB/T 15856.1-2002 ili ndi mfundo zotsatirazi: (amatchedwanso kuzungulira mutu kubowola mchira).

2. Cross recessed countersunk mutu kudzibowolera ndi kugogoda zomangira. Cross recessed countersunk head pobowola zomangira ndi kugogoda wononga ulusi Kukhazikitsa Muyezo: GB/T 15856.2-2002 ili ndi izi: (imadziwikanso kuti lathyathyathya mutu kubowola mchira, saladi mutu kubowola mchira).

3. Zomangira za hexagon flange mutu pobowola ndi kugogoda wononga ulusi. Kukhazikitsa muyezo: GB/T 15856.4-2002. Ili ndi izi: (yomwe imatchedwanso hexagonal Dahua drill tail, yomwe ndi imodzi mwazitsulo zomangira mchira. Zomwe zimagwiritsidwa ntchito kwambiri komanso zazikulu kwambiri.)

4. Zomangira za hexagon washer zobowola mutu zokhala ndi ulusi wogogoda. Kukhazikitsa muyezo: GB/T 15856.5-2002. Ili ndi izi: (yomwe imatchedwanso hexagonal small washer kubowola mchira.)
