Detailed Description
As shown in figures 1 to 5, a locking sealed fastening component, it adopts brand-new structural design, through set up a sealed safe cooperation locking groove and the sealed stable connection groove of fastening combination who mutually supports in sealed fastening component's internal assembly position, can cooperate the sealing washer to carry out accurate stable cooperation when the assembly is used and connect, guarantee inner structure has reliable leakproofness when the assembly, and can ensure that the sealing washer produces the skew, the whole security of later stage in the use has been improved, it is more convenient also to make the built-up connection operation when the assembly is fit for, efficiency in the assembling process is higher. The assembling and stabilizing connecting column comprises a cylindrical main body assembling and stabilizing connecting column 1 made of metal materials, wherein a cylindrical central assembling and combining connecting hole 2 penetrating through the end face of the right side of a part is formed in the end face of the left side of the main body assembling and stabilizing connecting column 1, and the position is combined and connected with an internal structural part during assembling. Be equipped with a cylindrical seal safe fit anti-loosening groove 3 on the inner cylinder face of center assembly built-up connection hole 2, can cooperate together with the sealing washer, report the sealing washer when the guarantee assembly can not drop, the operation during assembly is more convenient to can prevent after the later stage fastening cooperation that the sealing washer from producing the skew. The cross section of the sealing safety fit anti-loosening groove 3 is of a circular arc structure, four circular arc fastening combination sealing stable connecting grooves 4 with openings uniformly distributed on the circumference and towards the central assembly combination connecting hole 2 are formed in the inner cylindrical surface of the central assembly combination connecting hole 2, and after fastening combination, the sealing ring can be prevented from rotating, so that the stability of the sealing position is guaranteed. The fastening combination seal stable connection groove 4 surpasses in the projection region of left and right directions the sealed safe cooperation anti-loosening groove 3 is in the projected region of left and right directions, ensures that the action stability of preventing the direction of rotation is more reliable, and holistic seal stability can obtain better guarantee to can satisfy the user demand among the application environment that requires higher to seal stability in the mechanical component assembly.
Preferably, the sealing safety fit anti-loosening groove 3 is positioned at the center of the thickness of the main assembly stable connecting column 1 in the left-right direction, so that the stability of the whole structure is better, and the service life is longer when the connecting column is used.
