Description

Technical Field

[0001] The utility model relates to the technical field of studs, in particular to an adjustable stud. Background Art

[0002] Studs generally refer to double-ended studs, which are cylindrical fasteners with threads on both ends. They are widely used in electric power, chemical industry, oil refining, valves, railways, bridges, steel structures, auto parts, machinery, boiler steel structures, tower cranes, large-span steel structures and large buildings.

[0003] In real life, the length of the studs is mostly fixed and cannot be adjusted according to the actual situation. When encountering a deeper through hole, another stud needs to be selected, which affects the efficiency of the workers' fixing operations. At this stage, the length of the studs is adjusted by welding on the existing studs, which not only cannot guarantee the continuity of the stud threads, but also makes it impossible for the axes of the two to coincide.

[0007] The utility model is further configured that the extended sleeve hole is a round hole with a keyway hole.

[0008] The utility model is further configured that the bottom stud structure includes: a bottom stud and a bottom fitting hole; the upper wall surface of the bottom stud is provided with a bottom fitting hole, and the bottom stud is connected through the bottom fitting hole and the protruding structure of the extended stud.

[0009] The utility model is further configured that the bottom set hole is a round hole with a keyway hole.

[0011] The utility model is further configured that a through hole connected to the extended sleeve hole is opened on the side wall surface of the extended stud.

[0012] The utility model is further configured that a through hole connected to the bottom set hole is opened on the side wall surface of the bottom stud.

[0013] The beneficial effects of the utility model are as follows: the utility model adjusts the length of the stud by a snap-fit ​​connection method, and while being able to quickly extend the length of the stud, can also ensure the continuity of the stud thread, and can also allow the axis of the connected stud to coincide with the axis of the original stud; the adjustable stud achieves a snap-fit ​​connection method by extending the protruding structure and the extending the sleeve hole.
