Abstract
The utility model discloses a stud bolt, which comprises a first threaded rod (1), a polished rod (2) and a second threaded rod (3). The first threaded rod (1), the polished rod (2) and the second threaded rod (3) are sequentially integrally connected and coaxial, and the diameter of the first threaded rod (1) or/and the diameter of the second threaded rod (3) are smaller than that of the polished rod (2). The stud bolt has the advantages of fine stability of threaded connection and convenience in disassembling during maintenance.
Description
Technical field
The utility model relates to a kind of bolt, relates to a kind of stud bolt or rather.
Background technique
Stud bolt uses very extensive in machinery equipment, and the stud bolt of prior art comprises first threaded stem, polished rod and second threaded stem that is connected in one, described first threaded stem, polished rod and the second threaded stem coaxial line.First threaded stem, the polished rod of present double threaded screw are identical with the diameter of second threaded stem, and described first threaded stem and second threaded stem can adopt different thread, also can adopt the screw thread of identical pitch.The less stable that the threaded stem of this kind stud bolt is threaded with connected piece, the phenomenon that factor affecting can occur becoming flexible such as vibrated, during actual the use, normally filling out thread locking glue between the screw rod of link and stud bolt is locked, really can be anti-loosening by this kind mode, but dismounting is very inconvenient during maintenance, and the historical facts or anecdotes border is used unsatisfactory.
The model utility content
The technical problems to be solved in the utility model is the stud bolt of convenient disassembly when a kind of good stability that is threaded, maintenance are provided.
Technical solution of the present utility model is, a kind of stud bolt with following structure is provided, it comprises first threaded stem, polished rod and second threaded stem that is linked in sequence and becomes one, described first threaded stem, polished rod and the second threaded stem coaxial line, the diameter of the diameter of described first threaded stem or second threaded stem is less than the diameter of described polished rod.
After adopting above structure, the utility model double threaded screw compared with prior art has the following advantages:
Because the diameter of first threaded stem of stud bolt of the present utility model or/and the diameter of second threaded stem less than the diameter of described polished rod, when diameter than the little threaded stem of polished rod diameter be connected that bar is threaded and when locking, the end face of polished rod can be close to connected piece, like this, the end face of polished rod has individual position-limiting action to connected piece, make the good stability that threaded stem is threaded with connected piece, and need not to fill out the thread locking glue locking during actual the use between the two, make that dismounting is very convenient when keeping in repair, it is more satisfactory that double threaded screw is used.
Description of drawings
Accompanying drawing is the structural representation of the utility model double threaded screw.
Shown in the figure: 1, first threaded stem, 2, polished rod, 3, second threaded stem.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
See also shown in the accompanying drawing, the utility model double threaded screw comprises first threaded stem 1, polished rod 2 and second threaded stem 3 that is linked in sequence and becomes one, described first threaded stem 1, polished rod 2 and second threaded stem, 3 coaxial lines.The diameter of described first threaded stem 1 or/and the diameter of second threaded stem 3 less than the diameter of described polished rod 2, promptly comprise three kinds of situations, the diameter of described first threaded stem 1 is less than the diameter of described polished rod 2, the diameter of described second threaded stem 3 is less than the diameter of described polished rod 2, the diameter of the diameter of described first threaded stem 1 and second threaded stem 3 is all less than the diameter of described polished rod 2, in this specific embodiment, the diameter of the diameter of described first threaded stem 1 and second threaded stem 3 is all less than the diameter of described polished rod 2.According to actual needs, described first threaded stem 1 and second threaded stem 3 can adopt different thread, also can adopt the screw thread of identical pitch; The diameter of the diameter of described first threaded stem 1 and second threaded stem 3 can equate, also can be unequal.
During use, threaded stem screws in the tapped hole of connected piece, and after screwing, described connected piece can be close on the end face of described polished rod 2, and the end face of described polished rod 2 carries out the spacing loosening phenomenon of avoiding producing between threaded stem and the link to connected piece.
Claims (1)
1. stud bolt, it comprises first threaded stem (1), polished rod (2) and second threaded stem (3) that is linked in sequence and becomes one, described first threaded stem (1), polished rod (2) and second threaded stem (3) coaxial line is characterized in that: the diameter of described first threaded stem (1) or/and the diameter of second threaded stem (3) less than the diameter of described polished rod (2).
