Abstract

ELEMENTI ZA PRICVRSCIVANJE SA POKAZIVANJEM OPTERECENJA, pronalazak se odnosi na element za pricvrscivanje sa pokazivanjem opterecenja, kao sto je zavrtanj (10) ili goli zavrtanj, koji ima telo (12) koje je kod upotrebe podvrgnuto opterecenju na istezanje. telo (12) ima aksijalnu rupu (22) u koju se stavlja prva merna osovinica (30) ucvrscena svojim unutrasnjim krajem (32) za telo (12) i pruza se prema napolje preko ceone povrsine (16) elementa za pricvrscivanje. Element (40) za pokazivanje moze se obrtati na isturenom delu merne osovinice (30) izmedju ceone povrsine (16) elementa za pricvrscivanje i glave (34) osovinice (30), tako da se element (40) za pokazivanje slobodno obrce kada je telo (12) elemen-ta za pricvrscivanje nenapregnuto, ali kada je telo (12) podvrgnuto unapred odredjenom opterecenju na istezanje sprecen je da se obrce usled naleganja na ceonu povrsinu (26) elementa za pricvrscivanje. Druga merna osovinica (42) postavljena je u aksijalnu rupu (36) u prvoj mernoj osovinici (30) i ucvrscena je svojim unutrasnjim krajem i pruza se prema napolje preko spoljneg kraja prve merne osovinice (30). Drugi element (50) za pokazivanje moze se obrtati na ispuscenom delu druge merne osovinice (42) izmedju glave (46) osovinice (42) i prvog elementa (40) za pokazivanje. Drugi element (50) za pokazivanje moze slobodno da se obrce kada je telo (12) elementa za pricvrscivanje nenapregnuto ili je podvrgnuto prvom unapred odredjenom opterecenju, ali kada je telo (12) podvrgnuto drugom unapred odredjenom opterecenju na istezanje vecem od prvog unapred odredjenog opterecenja, drugi element (50) za pokazivanje sprecen je da se obrce usled naleganja na prvi element (40) za pokazivanje. Prvi element (40) za pokazivanje ukazuje kada je element za pricvrscivanje pritegnut na zeljeno opterecenje. Drugi element (50) za pokazivanje ukazuje kada je element za pricvrscivanje preopterecen.Load-indicating fastening elements The invention relates to a load-indicating fastening element, such as a screw (10) or a bare screw, having a body (12) which is subjected to a tensile load during use. the body (12) has an axial hole (22) into which the first measuring pin (30) is fastened by its inner end (32) to the body (12) and extends outwards over the end surface (16) of the fastening element. The indicating element (40) can be rotated on the protruding part of the measuring pin (30) between the end surface (16) of the fastening element and the head (34) of the pin (30), so that the indicating element (40) rotates freely when the body (12) the fastening element is unstressed, but when the body (12) is subjected to a predetermined tensile load, it is prevented from rotating due to its abutment on the front surface (26) of the fastening element. The second measuring pin (42) is placed in the axial hole (36) in the first measuring pin (30) and is fixed by its inner end and extends outwards over the outer end of the first measuring pin (30). The second pointing element (50) can be rotated on the dropped part of the second measuring pin (42) between the pin head (46) and the first pointing element (40). The second indicating element (50) can rotate freely when the body (12) of the fastening element is unstressed or subjected to a first predetermined load, but when the body (12) is subjected to a second predetermined tensile load greater than the first predetermined load. , the second pointing element (50) is prevented from rotating due to abutting the first pointing element (40). The first pointing element (40) indicates when the fastening element is tightened to the desired load. The second indicating element (50) indicates when the fastening element is overloaded.
