Description
Technical field
The present invention relates to a kind of stud, be specifically related to a kind of the most stubborn stud with cross threaded end.
Background technology
Stud, does not has head, only all outer threaded class securing member in two ends.During connection, its one end must be revolved
Entering in the part with internal thread hole, the other end passes in the part with through hole, then screws on nut, makes the two part tight
It is connected and is connected into an entirety.This type of attachment is referred to as Stud connection, is also belonging to removably connect.It is mainly used in connected zero
One of part thickness is relatively big, require compact conformation, or because dismounting is frequent, unsuitable occasion with bolts.
Existing stud, including stud bar, is usually disposed as two kinds of forms, and one is to offer screw thread on whole stud bar, or
Being that stud bar two ends symmetry offers screw thread, namely studs, as in figure 2 it is shown, there is following lacking in the stud of this spline structure
Fall into: one, with hands one end of thread screwed in part with internal thread hole generally by people and carry out pretension, due to manpower relatively
Little, and be cylindrical structure in the middle part of stud bar, thus cause stud efficiency of assembling low, and the screw thread progression of the end of thread is more,
Wasting time and energy, work efficiency is low, when dismantling one of them connection member, the when of often unscrewing nut simultaneously, and also can be whole
Individual stud bar is unscrewed or back-outs together with speeding up nut, so can cause needing again when ressembling parts to be screwed into stud,
Increase work workload and reduce work efficiency；Its two, after stud bar is selected into part, usually manpower or by aid will
Nut screwing clamping, if by manpower, nut is usually hexagonal shape and length is shorter, and lifting surface area is little, and when manpower is tightened, hands can be felt
Twinge and labor intensity are big, if also need very great strength by aid, and after stud puts into the through hole of connection member, due to sky
Between or the structure of connection member limit, possibly inserter or cannot be difficult at stud head, thus affect the fastening of stud, and then
Affect work to carry out in order.
Summary of the invention
The deficiency existed for prior art, the present invention provides a kind of the most stubborn stud with cross threaded end, logical
Crossing and arrange the cross termination that can be socketed aid, change manpower and stud bar is screwed in the drawback in union piece, save time province
Power, is improved assembling steadiness, is had the wing nut of handle by setting, increase and tighten lifting surface area, and pass through leverage
Increase and act on the torque on nut, while reducing labour force, realize the fastening of stud flexibly, be conducive to improving production and work
Make efficiency, convenient and practical, it is adaptable to multiple occasion.
In order to achieve the above object, the technical scheme that the present invention takes:
A kind of the most stubborn stud with cross threaded end, including stud bar, the upper/lower terminal of described stud bar is respectively
Being set to the upper and lower end of thread, the described upper end of thread is arranged with the nut being connected with it, the end of the described upper end of thread sets
There is the threaded end being connected with it, described threaded end offers the groove in decussate texture, described threaded end
For socket, stud bar can screw in the aid in the internal thread hole of connection member, described nut is symmetrically arranged on two with upwards
Bending and two handles in arc-shaped.
As optimal technical scheme, in order to expand connecing of the contact area of connection member and nut, beneficially connection member
Touch and tighten, ensure being firmly connected between stud bar and nut simultaneously, effectively prevent loosening between connection member, described upper spiral shell
Being arranged with the fit sealing part being connected with nut on stricture of vagina end, described fit sealing part is the molectron of spring shim and plain cushion.
Compared with prior art, the invention have the benefit that
1, stud bar is provided with the cross threaded end for being socketed aid, it is to avoid tradition is used artificial by stud bar
Screw in the drawback in connection member, stud bar can be screwed in by aid machinery, time saving and energy saving, improve assembling between parts
Steadiness, when effectively preventing from dismantling, whole stud bar is back-outed together with nut；Arranging the wing nut with handle, increase is tightened and is subject to
Power area, and act on the torque on nut by leverage increase, realize the tight of stud flexibly while reducing labour force
Gu, be conducive to improving production and work efficiency, convenient and practical, it is adaptable to multiple occasion.
2, it is set to the fit sealing part of the molectron of spring shim and plain cushion, expands the contact surface of connection member and nut
Long-pending, the beneficially contact of connection member is tightened, and ensures being firmly connected between stud and nut simultaneously, effectively prevents connection member
Between loosen.
Accompanying drawing explanation
With specific embodiment, the present invention is described in further detail below in conjunction with the accompanying drawings.

Detailed description of the invention
One specific embodiment of the present invention, a kind of the most stubborn stud with cross threaded end, bag are proposed as shown in Figure 1
Including cylindrical stud bar 1, the upper end of described stud bar 1 is set to upper end of thread 1-1, lower end is set to lower end of thread 1-2,
The middle part of described stud bar 1 is cylindrical connecting rod, and described upper end of thread 1-1 is arranged with the nut being connected with it
2, the end of described upper end of thread 1-1 is provided with the threaded end 3 being connected with it, and described threaded end 3 offers in ten
The groove 3-1 of character form structure, described threaded end 3 for socket stud bar 1 can be screwed in connection member internal thread hole auxiliary
Assistant engineer has, and pneumatically or electrically tighten throw, such as extrusion head that described aid is special are twisting of decussate texture
Tight throw, described nut 2 is symmetrically arranged on two with the two handle 2-1 being bent upwards and in arc-shaped, the circular arc of convex curved
Shape handle 2-1 increases and finger or the contact area of aid, effectively reduces the sensation of pricking of staff or acts on auxiliary work
Power on tool, and increased by leverage and act on the torque on nut 2, convenient and realize between connection member flexibly tight
Gu.
Being arranged with the fit sealing part 4 being connected with nut 2 on described upper end of thread 1-1, described fit sealing part 4 is spring
Pad and the molectron of plain cushion, fit sealing part 4 can expand the contact area of connection member and nut 2, beneficially connecting portion
The contact of part is tightened, and ensured upper being firmly connected between end of thread 1-1 with nut 2 simultaneously, and effectively prevented between connection member
Loosen.
When the present invention uses: utilize special throw of pneumatically or electrically tightening to be set on threaded end 3, by stud
After in the internal thread hole of the lower end of thread 1-2 screw-in connection member of bar 1, upper end of thread 1-1 is through the through hole of another connection member
In, plain cushion 4-2, spring shim 4-1, nut 2, threaded end 3 are sequentially sleeved on stud bar 1, recycling artificial hand stubborn or
Act on handle 2-1 by opening or double offset ring spanner, so that it may convenient, flexible nut 2 is tightened on stud bar 1, i.e.
Stud between parts can be realized be fastenedly connected, time saving and energy saving.If dismounting connection member, unclamp threaded end 3, only need artificial or
By aid opposite direction rotary handle 2-1, until nut 2 loosens with the upper end of thread, upper connection member can be dismantled, and
Lower end of thread 1-1 also adapter sleeve is located in the internal thread hole of lower connection member.
Certainly, the most simply combine accompanying drawing the preferred embodiments of the disclosure to be described in detail, not with this
Limit the practical range of the present invention, the equivalence change that all principles under this invention, structure and structure are made, all should be covered by this
In the protection domain of invention.
