Abstract
A disposable fixed torque nut comprises a nut main body fixed on a moment bearing body; at least one trapezoid connecting sheet is arranged on the moment bearing body; and the thinner bottom edge of the connecting sheet is connected with the nut main body. The nut adopting the technical scheme has the advantage that as the moment bearing body and the connecting sheet are arranged, when the nut main body is screwed to a certain extent, the moment exerted on the moment bearing body through a wrench is increased correspondingly when the stress is increased, and when the moment reaches the bearing limit of the connecting sheet, the connecting sheet is broken from the part connected with the nut main body. Therefore, the purpose of protecting the nut and mounted equipment is achieved, and the service life of the nut is prolonged.
Description
Technical field
The utility model belongs to hardware fastening, specifically relates to a kind of torque nut that one-time fixes.
Background technique
Nut is an installation operation stock commonly used.In the process that bolt is installed, need nut is fastening, simultaneously according to equipment installation requirement standard, nut also requirement can not be stressed excessive, otherwise may damage installed device, perhaps causes the screw bolt and nut thread abrasion.Nut is stressed excessive when preventing erection unit, and fitness for purpose is used torque spanner, realizes the stressed unanimity of each nut like this, and the screw thread of protecting nut, bolt is not by damage on the one hand, and the equipment that protection simultaneously is mounted is firm.
General nut mostly is integrative-structure, only need use spanner to block nut during tightening nut, by spanner nut is applied external force, reaches the purpose of tightening nut.It is firmly excessive often to occur spanner in the practical operation, causes the phenomenon that nut thread damages or bolt thread damages, and perhaps damages for fear of nut bolt, and wrench torque is less than normal, the requirement that the equipment that do not reach is fastening.In order to guarantee the nut installation specification, generally use torque spanner, when moment reached fixed value, spanner can not increase moment again, but can't implement at part working zone torque wrench.Sometimes because the workmen does not have torque spanner, cause tightening nut stressed excessive, nuts and bolt damages.
Summary of the invention
The purpose of this utility model provides a kind of torque nut that one-time fixes, and under the situation of not using torque spanner, realizes that the nut installation is fastening, installation dynamics unanimity.
For achieving the above object, the utility model is by the following technical solutions:
The utility model comprises nut main body, and described nut main body is fixed on the moment bearing object; On described moment bearing object at least one connecting sheet is set, connecting sheet is a trapezium structure, and wherein narrower base is connected with nut main body in the connecting sheet.
Described nut main body, connecting sheet and moment bearing object are fixed to be one.
Described moment bearing object is a regular polygon.
Described connecting sheet is rounded even distribution on the moment bearing object.
Adopt the utility model of technique scheme; owing to be provided with moment bearing object and connecting sheet; like this when nut main body is fastened to a certain degree; along with stressed increase; the spanner effect also can correspondingly increase for the moment of moment bearing object, and when moment reached the stressed limit of connecting sheet, connecting sheet will be from rupturing with the nut main body joint; thereby reach the purpose of protection nut and institute's erection unit, the working life of having improved nut.
Description of drawings
Accompanying drawing is overall structure figure of the present utility model.
Embodiment
As shown in the figure, the utility model comprises nut main body 1, and nut main body 1 is fixed on the moment bearing object 3; At least one connecting sheet 2 is set on moment bearing object 3.Wherein, moment bearing object 3 is a regular polygon, is preferred forms with the regular hexagon, the rounded even distribution on moment bearing object 3 of connecting sheet 2 this moment.
For realizing that the utility model connecting sheet 2 is a trapezium structure, this trapezium structure also can be irregular trapezoidal, and it has a minor face, a long limit and two sides.When connecting sheet 2 rounded distributions, two sides are camber line.But, in any case, base narrower in the connecting sheet 2 always is connected with nut main body 1, guarantees that promptly the connecting sheet 2 and the joint of nut main body 1 are connecting sheet 2 the narrowest the thinnest positions, to to a certain degree the time, connecting sheet 2 at first ruptures with the joint of nut main body 1 when stressed.
In addition, above-mentioned nut main body 1, connecting sheet 2 and moment bearing object 3 can also be fixed be one.
Working principle of the present utility model is:
Because connecting sheet 2 is connecting sheet 2 the narrowest the thinnest positions with nut main body 1 joint.Spanner blocks moment bearing object 3 when installing and using, and by spanner moment of rotation bearing object 3, drives nut main body 1 rotation, reaches the purpose of tightening nut main body 1.When nut main body 1 is fastened to a certain degree; along with stressed increase; the spanner effect also can correspondingly increase for the moment of moment bearing object 3; when moment reaches the stressed limit of connecting sheet 2; connecting sheet 2 will be from rupturing with nut main body 1 joint; increase stressed this moment, and nut main body 1 can not rotate thereupon yet, thereby reach the purpose of protection nut and institute's erection unit.
