Abstract
The utility model discloses a shear nut which is in the shape of a stepped tube made of zinc-aluminum alloy. A hexagon head is arranged at one end of the shape, a round head is arranged at the other end of the shape, a shear portion circular groove is formed in the middle of the shape, inner holes are through stepped holes, the inner hole corresponding to the round head end of the shape is a hexagon hole of a hexagon head nut matched with a bolt, and the others are small round holes. The shear nut is made of the zinc-aluminum alloy, light and not prone to corrosion; even though residual parts of the nut which is twisted off are not removed after actual installation, corrosion on an inner clamping nut will not be caused, and installation needs of a tension clamp can be met.
Description
Technical field
The utility model relates to a kind of shearing nut.
Background technique
At present, shearing nut of the prior art, be disclosed a kind of torque nut in 200820082358.3 as the patent No., comprise up and down cylindricality layout, be provided with a nut in cylindrical body inside, lower end, the recessed lower end of this nut cylindrical body is inner, and it adopts engineering plastics to do the shell integral injection molding, and its material and performance can not satisfy the installation requirements of strain clamp.
Summary of the invention
Technical problem to be solved in the utility model, just be to provide a kind of shearing nut, this is sheared nut and adopts the allumen material, lightweight and be difficult for corrosion, even if after as installed, remaining nut after not twisting into two parts is removed, and also can not produce corrosion to the turnbuckle of inside, can satisfy the installation requirements of strain clamp.
It is as follows that the utility model solves the problems of the technologies described above the technological scheme that adopts:
A kind of shearing nut, it is characterized in that: be allumen ladder tubulose, one end of profile is that hexagon head, the other end are that round end, centre are the cut part circular groove, endoporus is the shoulder hole that connects, corresponding to the endoporus of profile blunt end for adapt to the hexagon ring of the hex-head nut of bolt matching, all the other are small sircle hole.
As a kind of improvement of the present utility model: also be provided with round platform between hexagon head described in the utility model and groove type cut part.
Further improve as of the present utility model: profile blunt end described in the utility model has relative milling flat.
The utlity model has following advantage:
(1) the utility model is sheared nut and is adopted the allumen material, lightweight and be difficult for corrosion.Even if after as installed, the remaining nut after not twisting into two parts is removed, and also can not produce corrosion to the turnbuckle of inside;
(2) the utility model is sheared the moment of torsion that nut can reach standard-required, and the power that axially fastens that produces also can satisfy the installation requirements of strain clamp;
Moment of torsion when (3) the utility model shearing nut is twisted into two parts and the power that axially fastens of generation are all comparatively stable;
(4) the utility model adopts and shears fastening nuts, need not torque spanner and just can reach expection moment values and axial clamping force, not only facilitates installation also to reduce the impact of personal factor.
Description of drawings
Fig. 1 is the overall diagram of the shearing nut in embodiment;
Fig. 2 is the plan view of Fig. 1;
Fig. 3 is that the A-A of Fig. 2 is to sectional view;
Fig. 4 is the erection drawing when shearing the nut application in embodiment.
Embodiment
As Figure 1-3, a kind of shearing nut, be allumen ladder tubulose, one end of profile is that hexagon head 1, the other end are that round end 2, centre are cut part circular groove 3, endoporus is the shoulder hole that connects, corresponding to the endoporus of profile blunt end for adapt to the hexagon ring 5 of the hex-head nut of bolt matching, all the other are small sircle hole 6.
Also be provided with round platform 4 between hexagon head and groove type cut part.
The profile blunt end has relative milling flat 7.
As shown in Figure 4, during practical application, bolt 11 passes the hex-head nut 8 of screwing on after pad 10, spring washer 9, then put the shearing nut, wherein hex-head nut 8 just is embedded in shearing nut hexagon ring 5, when the power that axially fastens that is applied to the moment of torsion of shearing the applied force on nut hexagon head 1 or generation reach the moment of torsion of twisting into two parts circular groove 3 or generation axially fasten power the time, circular groove 3 just disconnects.
The utility model is sheared nut and is adopted the allumen material, lightweight and be difficult for corrosion, even if after as installed, the remaining nut after not twisting into two parts is removed, and also can not produce corrosion to the turnbuckle of inside.
The utility model is sheared the moment of torsion that nut can reach standard-required, and the power that axially fastens that produces also can satisfy the installation requirements of strain clamp; Moment of torsion when the shearing nut is twisted into two parts and the power that axially fastens of generation are all comparatively stable; The utility model adopts shears fastening nuts, need not torque spanner and just can reach expection moment values and axial clamping force, not only facilitates installation also to reduce the impact of personal factor.
Claims (3)
1. shear nut for one kind, it is characterized in that: be allumen ladder tubulose, one end of profile is that hexagon head, the other end are that round end, centre are the cut part circular groove, endoporus is the shoulder hole that connects, corresponding to the endoporus of profile blunt end for adapt to the hexagon ring of the hex-head nut of bolt matching, all the other are small sircle hole.
2. shearing nut according to claim 1, is characterized in that: also be provided with round platform between described hexagon head and cut part groove type.
