Description
Technical field
This utility model is related to a kind of stud, and in particular to a kind of easily stubborn stud with cross threaded end.
Background technology
Stud, does not have head, the only outer threaded class securing member in two ends.During connection, its one end must revolve
In entering the part with internal thread hole, then the other end screws on nut through in the part with through hole, makes the two parts tight
It is connected and is connected into an entirety.This type of attachment is referred to as Stud connection, is also belonging to be detachably connected.It is mainly used in being connected zero
One of part thickness is larger, require compact conformation, or because of dismounting frequently, unsuitable occasion with bolts.
Existing stud, including stud bar, are usually disposed as two kinds of forms, and one is to offer screw thread on whole stud bar, or
It is that stud bar two ends symmetrically offer screw thread, that is, studs, as shown in Fig. 2 the stud of this spline structure has following lacking
Fall into：First, generally by people with handss will an end of thread screw in internal thread hole part in carry out pretension, due to manpower compared with
It is little, and stud bar middle part is cylindrical structure, so as to cause stud efficiency of assembling low, and the screw thread series of the end of thread is more,
Waste time and energy, work efficiency is low, at the same when dismantling one of connection member, when often unscrewing nut, also can be whole
Individual stud bar is unscrewed or is back-outed together with nut is speeded up, and so can cause be screwed into stud again when part is ressembled,
Increase work workload and reduce work efficiency；Second, stud bar is selected into after part, usually manpower or will by aid
Nut screwing clamping, if by manpower, nut is usually hexagonal shape and length is shorter, and lifting surface area is little, and handss can be felt when manpower is tightened
Twinge and high labor intensive, if also needing very great strength, and stud to be put into after the through hole of connection member by aid, due to sky
Between or connection member structure limit, at stud head possibly inserter or cannot be difficult to, so as to affect the fastening of stud, and then
Work is affected to carry out in order.
Utility model content
In view of the shortcomings of the prior art, this utility model provides a kind of easily stubborn spiral shell with cross threaded end
Post, by arranging the cross termination of aid can be socketed, and the drawbacks of changing manpower and stud bar is screwed in union piece, saved
Shi Shengli, improves assembling steadiness, and by arranging the wing nut with handle, lifting surface area is tightened in increase, and by lever
Effect increase acts on the torque on nut, reduces flexibly realizing the fastening of stud while labour force, is conducive to improving production
And work efficiency, it is convenient and practical, it is adaptable to various occasions.
In order to achieve the above object, the technical scheme that this utility model is taken：
A kind of easily stubborn stud with cross threaded end, including stud bar, the upper/lower terminal difference of the stud bar
The upper and lower end of thread is set to, the nut being connected with it is arranged with the upper end of thread, the end of the upper end of thread sets
There is the threaded end being connected with it, the groove in decussate texture, the threaded end are offered on the threaded end
Stud bar can be screwed in the aid in the internal thread hole of connection member for socket, the nut is symmetrically arranged on two with upwards
Bending and two handles in arc-shaped.
As optimal technical scheme, in order to expand the contact area of connection member and nut, be conducive to connecing for connection member
Touch and tighten, while ensureing the firm connection between stud bar and nut, effectively prevent the loosening between connection member, the upper spiral shell
The fit sealing part being connected with nut is arranged with stricture of vagina end, the fit sealing part is the molectron of spring shim and plain cushion.
Compared with prior art, this utility model has the advantage that：
1st, stud bar is provided with the cross threaded end for being socketed aid, it is to avoid tradition is with manually by stud bar
The drawbacks of screwing in connection member, can screw in stud bar by aid machinery, time saving and energy saving, improve what is assembled between part
Steadiness, whole stud bar is back-outed together with nut when effectively preventing dismounting；Wing nut with handle is set, and increase is tightened and received
Power area, and the torque on nut is acted on by leverage increase, reduce flexibly realizing the tight of stud while labour force
Gu, be conducive to improving production and work efficiency, it is convenient and practical, it is adaptable to various occasions.
2nd, the fit sealing part of the molectron of spring shim and plain cushion is set to, expands the contact surface of connection member and nut
Product, the contact for being conducive to connection member is tightened, while ensureing the firm connection between stud and nut, effectively prevents connection member
Between loosening.
Description of the drawings
Below in conjunction with the accompanying drawings this utility model is described in further detail with specific embodiment.
Fig. 1 is structural representation of the present utility model；
The structural representation of the existing studs of Fig. 2；
Drawing reference numeral：1st, stud bar, 1-1, the upper end of thread, 1-2, the lower end of thread, 2, nut, 2-1, handle, 3, the end of thread
