Detailed Description
As shown in figures 1 to 7, a durable accessory of expansion joint combination fastening, it adopts brand-new structural design, the fastening mounted position of the axle type subassembly of cooperation expansion joint cooperates the connection when using, can provide closely firm cooperation for the assembly structure, and the bulk strength when combining is higher, whole durability when using is stronger, the bearing capacity is bigger, can satisfy the user demand under the multiple application environment, the guarantee is higher at the whole security when using, stability in use is more reliable. It includes and is made and the center pin is cylindrical main part erection joint support post 1 of upper and lower direction by metal material, main part erection joint support post 1's upper end is equipped with integrated into one piece and outside cross-section is stable spliced pole 2 for convex sealed combination, through its sealed stability when guaranteeing the erection joint. The lower end center position of main part installation connection support column 1 is equipped with the cylindrical main part cooperation installation connecting hole 3 that runs through the part upper end completely, and it carries out inseparable cover with axle type subassembly and is in the same place. The upper end of the sealed combination stable connection column 2 is provided with a sealed combination connection installation groove 4 which is communicated with the main body matching installation connection hole 3 and has a circular arc-shaped section, so that the sealing performance of the internal matching position is guaranteed. The inner side of the sealing combination connection installation groove 4 is provided with an inner combination sealing stable groove 5 with a circular arc-shaped section, and the sealing combination stable groove can be matched with a sealing ring to carry out tight and stable combination, so that the sealing safety of the inner part is higher. The outer circular arc-shaped structure of the sealing combination stable connection column 2 is provided with an external combination sealing safety column 6 which is integrally formed and has a semicircular section, so that the combination sealing performance of the outer position is better.
