Detailed Description
As shown in fig. 1 to 7, a sealed firm type fastener, it adopts brand-new structural design, through the anti-skidding fastening integrated configuration of inside and outside when assembling, can carry out inseparable combination with mounted position seal fitting, still make the cooperation position have reliable locking effect under the prerequisite of guaranteeing sealing stability, the security when using is higher, its major structure can ensure the convenience when installing stronger through the reference column when the assembly, assembly efficiency is higher, the assembly precision is more reliable, durability when using is stronger. The assembling and fixing device comprises a cylindrical main body fastening and combining connecting column 1 made of metal materials, wherein an integrally formed conical mounting, positioning and matching stabilizing column 2 is arranged at the center of the upper end of the main body fastening and combining connecting column 1, and the assembling and combining precision of the whole body can be guaranteed when the assembling is carried out. The commodity leaving position of the main body fastening combination connecting column 1 is provided with a cylindrical main body fastening connection combination groove 3, the inner cylindrical surface of the main body fastening connection combination groove 3 is provided with an assembly combination connection thread groove, and the whole fastening matching is carried out through the assembly combination connection thread groove. The upper end of the main body fastening and connecting combination groove 3 is provided with six groups of internal anti-skidding tight safe connection grooves 5 which are uniformly distributed on the circumference, and the six groups of internal anti-skidding tight safe connection grooves can be tightly matched with a sealing gasket in the internal combination process. The upper end edge position of main part fastening combination spliced pole 1 is equipped with the sealing combination connection circular arc, be equipped with circular arc outside antiskid combination stable groove 4 of circumference evenly distributed on the sealing combination connection circular arc, can carry out inseparable stable combination with sealed the pad when carrying out the cooperation in the outside and be in the same place.
