Abstract
The utility model discloses a kind of easy-to-mount double end stud connecting piece, belong to technical field of fastening.This anticreep studs, is less than the external diameter of described polished rod including the first threaded rod, polished rod and the second threaded rod that axially vertically link into an integrated entity successively, the external diameter of described first threaded rod and the external diameter of the second threaded rod；It is provided with some fins, described each fin circumference uniform distribution along described smooth rod outer surface radial convex.This easy-to-mount double end stud connecting piece, the diameter of the first threaded rod and the diameter of the second threaded rod are less than the diameter of polished rod, nut fastening performance is stronger, it is provided with some fins along light rod outer surface radial convex, increase the frictional force between stud and securing objects, make studs be difficult to rotate therewith when spinning nut, facilitate fastening and the dismounting of stud.
Description
Technical field
This utility model belongs to technical field of fastening, is specifically related to a kind of easy-to-mount double end stud connecting piece.
Background technology
As a kind of connection securing member in machinery, stud has been widely used in industry-by-industry, but tightening and taking out of studs is a bigger difficult problem, at present, double end stud screwing and taking out be generally the most first with two nuts one end of stud mutually carry on the back tight after, then realize fastening and the dismounting of stud with the nut of the hexagon rotation studs other end.This mode not only troublesome poeration, and reliability is relatively low, uses and wastes time and energy.
Utility model content
The purpose of the application is to provide a kind of easy-to-mount double end stud connecting piece so that stud studs during installation and removal is difficult to nut rotation.
For realizing object above, the technical solution adopted in the utility model is: easy-to-mount double end stud connecting piece, the external diameter of described polished rod it is less than including the first threaded rod, polished rod and the second threaded rod that axially vertically link into an integrated entity successively, the external diameter of described first threaded rod and the external diameter of the second threaded rod；It is provided with some fins, described each fin circumference uniform distribution along described smooth rod outer surface radial convex.
Described first threaded rod is provided with First Transition circular arc with the junction of described polished rod.
Described second threaded rod is provided with the second transition arc with the junction of described polished rod.
Easy-to-mount double end stud connecting piece of the present utility model, including the first threaded rod, polished rod and the second threaded rod that axially vertically link into an integrated entity successively, the external diameter of the first threaded rod and the external diameter of the second threaded rod are less than the external diameter of described polished rod, when can make nut fastening stud, it is close to the polished rod part of stud, increase the contact area of nut and polished rod, strengthen the fastening performance of nut.It is provided with some fins along light rod outer surface radial convex, each fin circumference uniform distribution, the setting of fin increases the frictional force between studs surface and securing objects so that studs is difficult to rotate therewith when spinning nut, facilitates fastening and the dismounting of stud.
Easy-to-mount double end stud connecting piece of the present utility model, the first threaded rod is provided with First Transition circular arc with the junction of polished rod.Second threaded rod is provided with the second transition arc with the junction of polished rod.The setting of transition arc makes the stress between nut and stud less, prevents stud nut when being given a shock from occurring loosening phenomenon.
Accompanying drawing explanation
Fig. 1 is the easy-to-mount double end stud connecting piece structural representation of this utility model embodiment；
Fig. 2 is the sectional view of the easy-to-mount double end stud connecting piece polished rod of this utility model embodiment.
Detailed description of the invention
Below in conjunction with detailed description of the invention, the utility model is described in further detail.
The embodiment of easy-to-mount double end stud connecting piece of the present utility model is as depicted in figs. 1 and 2.
The easy-to-mount double end stud connecting piece of the present embodiment, is less than the external diameter of polished rod 3 including the first threaded rod 2, polished rod 3 and the second threaded rod 4 that axially vertically link into an integrated entity successively, the external diameter of the first threaded rod 2 and the external diameter of the second screw thread 4；It is provided with some fins 5, each fin 5 circumference uniform distribution along polished rod 3 outer surface radial convex.The setting of fin 5 increases the frictional force between studs surface and securing objects so that studs is difficult to rotate therewith when spinning nut, facilitates fastening and the dismounting of stud.
Further, the first threaded rod 2 is provided with First Transition circular arc 1 with the junction of described polished rod 3.Second threaded rod 4 is provided with the second transition arc 6 with the junction of described polished rod 3.The setting of transition arc makes the stress between nut and stud less, prevents stud nut when being given a shock from occurring loosening phenomenon.
Claims (3)
1. an easy-to-mount double end stud connecting piece, including the first threaded rod, polished rod and the second threaded rod that axially vertically link into an integrated entity successively, it is characterised in that the external diameter of described first threaded rod and the external diameter of the second threaded rod are less than the external diameter of described polished rod；It is provided with some fins, described each fin circumference uniform distribution along described smooth rod outer surface radial convex.
Easy-to-mount double end stud connecting piece the most according to claim 1, it is characterised in that described first threaded rod is provided with First Transition circular arc with the junction of described polished rod.
Easy-to-mount double end stud connecting piece the most according to claim 1, it is characterised in that described second threaded rod is provided with the second transition arc with the junction of described polished rod.
