Abstract
The utility model discloses a lifting eye nut. The lifting eye nut comprises a lifting eye part and a nut part, wherein a thread is arranged at the upper end inside a screw hole of the nut part, the lower end of the nut part is provided with an unthreaded clearance groove. The clearance groove solves the problem that a stud connected with the lifting eye nut easily factures at the end of the thread when the lifting eye nut is subjected to loads inclining or perpendicular to the plane of the lifting eye in a using process; therefore, a situation that the hoisted machines and devices are damaged due to facture of the stud in the hoisting process is avoided, a hoisting operator is prevented from injury and potential safety hazards are reduced.
Description
One, technical field
The utility model relates to a kind of mechanical component gauge member, is specifically related to a kind of eyenut.
Two, background technology
Eyenut is a kind of mechanical component gauge member that is widely used in lifting machinery, utensil, eyenut and double-screw bolt are threaded connection, double-screw bolt is connected in any way with lifted machinery, utensil, or double-screw bolt is the part on lifted machinery, utensil.Its screw of prior art eyenut is perfect thread structure, after equipped with double-screw bolt, the screw tip of double-screw bolt is just in time near the bottom surface plane of eyenut, and the screw tip of double-screw bolt is the thin spot of double-screw bolt intensity, in the course of the work when being tilted or during perpendicular to the load of suspension ring plane, it is subject to the tangential force effect that transmit eyenut bottom, tends to make double-screw bolt at screw tip generation fracture defect.
Three, summary of the invention
The purpose of this utility model is to provide a kind of new eyenut, solves eyenut in use, because being tilted or making the double-screw bolt connecting with it that the problem of fracture easily occur at screw tip perpendicular to the load of suspension ring plane.
Principle of the present utility model and technical scheme are: a kind of eyenut, comprise suspension ring part and nut portion, at one section of threadless undercut of screw tip designs of nut portion, described screw inner upper end is screw thread, and lower end is one section of threadless undercut.After eyenut and double-screw bolt are equipped, the position of the screw tip that the existence of this undercut makes spiro column in eyenut screw rises to this undercut inside, between this undercut part in eyenut screw and one section of threadless spiro column external diameter, has certain interval.
Undercut in above-mentioned eyenut screw, its diameter dimension D
kequal or be slightly larger than the corresponding Major Diam D of screw thread specification, as D
kscope can be: D≤D
k≤ D+0.1D; Its height dimension h sets as required, as the scope of h can be set as 0.5D≤h≤2D.
The beneficial effects of the utility model are: when eyenut is tilted or perpendicular to the load of suspension ring plane, cause after the distortion of double-screw bolt generation slight curves, first eyenut nut portion undercut end contacts with threadless external diameter corresponding position on double-screw bolt, when load further strengthens, double-screw bolt can occur to be out of shape compared with macrobending near above-mentioned contact site and circumference, and the screw tip of double-screw bolt is because being positioned at eyenut undercut, directly do not contact with eyenut nut portion undercut end, only there is infinitesimal deformation, can not produce stress concentrates, thereby avoid double-screw bolt at screw tip breakage problem.
A kind of eyenut of employing the utility model further beneficial effect is: can avoid damaging because double-screw bolt fracture causes lifted machinery, utensil in hoisting process, prevent that hoisting personnel is subject to personal injury, reduce potential safety hazard.

Fig. 2: be a kind of eyenut of the utility model and Stud connection schematic diagram;
Fig. 3: be a kind of eyenut of the utility model and the stressed schematic diagram of double-screw bolt cooperating.

Five, the specific embodiment
Below in conjunction with accompanying drawing, embodiment is elaborated.
A kind of eyenut of the utility model, comprises suspension ring part 1 and nut portion 2, and nut portion 2 screw inner upper end are screw thread, and lower end is one section of threadless undercut 3, this undercut 3 its diameter dimension D
kbe slightly larger than the corresponding Major Diam D of screw thread specification, D
kscope be D≤D
k≤ D+0.1D; Its height dimension h sets as required, and the scope of h is 0.5D≤h≤2D.
In the course of the work, when eyenut is tilted or perpendicular to the load of suspension ring plane, and cause after the distortion of double-screw bolt generation slight curves, first undercut 3 ends of eyenut nut portion 2 contact with threadless external diameter corresponding position A on double-screw bolt 4, when load further strengthens, double-screw bolt 4 can occur to be out of shape compared with macrobending near above-mentioned contact site A and circumference, and the screw tip of double-screw bolt 4 is because being positioned at eyenut undercut 3, directly do not contact with described undercut 3 ends, only there is infinitesimal deformation, can not produce stress concentrates, thereby avoid double-screw bolt 4 at screw tip breakage problem.
By using a kind of eyenut of the utility model, can avoid damaging because double-screw bolt fracture causes lifted machinery, utensil in hoisting process, prevent that hoisting personnel is subject to personal injury, reduce potential safety hazard.
It should be pointed out that those skilled in the art are not departing from the improvement of making under the prerequisite of the utility model know-why, within all should being included in protection domain of the present utility model.
