Detailed Description
As shown in figures 1 to 6, a fastening anti-loosening type connecting piece adopts a brand-new structural design, through the double-sealing matching groove at the upper position and the lower position when fastening connection is carried out, connection sealing performance and fastening anti-loosening effect when the connecting piece is used can be guaranteed, the safety when the connecting piece is used is guaranteed to be better, the combination strength is more reliable, the fastening connection requirements under various application environments can be met, the application range when the connecting piece is used is wider, the combination life when the connecting piece is used can be further prolonged, and the overall safety in the using process is higher. The connecting column comprises a cylindrical main body fastening matching connecting column 1 with a central shaft in the vertical direction, and a main body fastening matching thread is arranged on the outer cylindrical surface of the main body fastening matching connecting column 1 and is a main body matching structure when the whole body is installed and connected. The lower extreme of main part fastening cooperation spliced pole 1 is equipped with integrated into one piece's cylindrical sealed end position and stabilizes spliced pole 2, has the sealed complex dual combined action of end position and second. The diameter of the main body fastening matching connecting column 1 is smaller than that of the sealing stop stable connecting column 2. The upper end of main part fastening cooperation spliced pole 1 is equipped with the sealed anti loosening structure 3 of main part fastening connection, and it ensures that the upper end position can carry out firm inseparable cooperation with the sealed combination pad when closely cooperating, has reliable cooperation locking effect to can ensure the intensity of cooperation connection. The sealed anti-loosening structure 3 of main part fastening connection comprises six locking combination spread grooves of circumference evenly distributed, every group locking combination spread groove is constituteed by four openings upwards and will the sealed stable groove of cooperation of semi-cylindrical that the outer face of cylinder of main part fastening cooperation spliced pole 1 runs through completely constitutes adjacent two not communicate with each other between the locking combination spread groove, ensures that the combined strength of the sealed locking position in upper end is more reliable.
