Abstract
The present invention relates to an assembling component with a screw nut and a washer, which is composed of a screw nut and a washer. One surface of the screw nut is provided with wedge-shaped inclined surfaces which are arranged in an equal angle and are in the shape of an inclined pushing surface. One side of each wedge-shaped inclined surface is high, and one side of each wedge-shaped inclined surface is low. The engaging parts of the wedge-shaped inclined surfaces form blocking surfaces with height dropping differences. The center of the washer is provided with a through hole. One surface of the washer forms continuous inclined surfaces which are correspondingly engaged with the wedge-shaped inclined surfaces of the screw nut, the engaging surfaces of the continuous inclined surfaces form bearing surfaces with height dropping differences, and the other surface of the washer is provided with a plurality of pointed grooves. Each pointed groove is provided with a vertical surface and an inclined surface. The push-inclined direction of each inclined surface is identical to the push-inclined direction of each continuous inclined surface. The periphery of each wedge-shaped inclined surface of the screw nut outward and continuously extends to form a flange surface. A cylindrical ring matched with the matched center hole of the washer is integrally formed under the flange surface. The present invention can obtain the effects of loosening prevention and theft prevention by the braking effect between the screw nut and the washer and the combination of the outer surface of a workpiece and the pointed grooves.
Description
Technical field
The present invention relates to fastening piece, especially a kind of assembly parts of nut washer of forming by nut and pad.
Background technique
At present, nut and pad normally fitted bolt are formed fastener assembly, they use more extensive in actual life as structural connection, such as in building construction, the Rail Highway bridge construction, application is all arranged in the every field such as engineering construction, its fastening structure is to be interted in link by bolt, the other end cover Upper gasket of bolt, it is tightened fixing by being threaded of nuts and bolt, because above-mentioned nut and gasket construction are fairly simple, they cooperate the fixing effect of just playing by simply being threaded with bolt, thereby under high temperature or dither impact, cause nut easily, slope of thread between bolt slides mutually, makes nut, bolt produces towards loosening direction and rotates, and makes bolt, nut gets loose, in case bolt, serious contingency very easily takes place in nut loosening or come off.In addition, this simple cooperating structure, nut also are easy to be disassembled by light instrument by others, can not be antitheft effectively, do not have anti-theft feature.
Summary of the invention
Purpose of the present invention provides a kind of assembly parts of nut washer of getting loose automatically of being difficult under high temperature, dither impact.
In order to achieve the above object, technological scheme of the present invention is: a kind of assembly parts of nut washer, comprise nut, pad, be respectively arranged with several breach on the edge of nut and pad, a nut wherein end is a hexagon, and the end face of its other end is provided with the equiangularly arranged and high low wedge shape inclined-plane that is inclined thrust surface on one side on one side, and each wedge shape inclined-plane joins continuously simultaneously, bosom, last wedge shape inclined-plane just is next the most shallow place, wedge shape inclined-plane, and each wedge shape inclined-plane joining place forms the block face of the high low head of tool; The central authorities of pad are provided with perforation, pad one side wherein is formed with and the corresponding continuous inclined-plane that agrees with, each wedge shape inclined-plane of nut, the thickness on last inclined-plane just is next oblique thinnest part, the joining place on each continuous inclined-plane forms the bearing surface of the high low head of tool, the another side of pad is provided with several pointed grooves, described pointed groove tool one facade and an inclined-plane, the inclined-plane push away tilted direction and continuous inclined-plane to push away tilted direction identical, the periphery on nut wedge shape inclined-plane outwards extends to form flanged surface continuously, and the below of this flanged surface is formed with the cylindricality ring that cooperates with supporting pad central hole.
Nut one end of this programme is a hexagon, the other end of nut has flanged surface, the bottom surface of this flanged surface is provided with the wedge shape inclined-plane that joins continuously, be formed with on the one side of pad and the corresponding continuous inclined-plane that agrees with, each wedge shape inclined-plane of nut, the another side of pad is provided with several pointed grooves, work as nut, during pad fitted bolt fixation workpiece, swivel nut, the bearing surface drive pad rotation that the block face of nut is pushed pad tightens up workpiece, if nut is wanted reverse start, because the wedge shape inclined-plane of nut and the continuous inclined-plane of pad compress mutually and contend with, add workpiece be heated the back outer surface expand with pad mistake connected in star facade between resistivity, make nut, pad and bolt all are difficult for getting loose.In addition because the edge of nut and pad is provided with several breach, as when wanting loose nut and pad, need with special tool(s) simultaneously turnbuckle and pad just turn, thereby have antitheft effect.After bolts and nuts, pad cooperate installation, because behind the workpiece expanded by heating, its outer surface combines with the pointed groove facade of pad, also can reach antitheft effect.The below of nut flanged surface is formed with the cylindricality ring that cooperates with supporting pad central hole, its objective is when swivel nut and pad, and nut is easy to promote the pad rotation, and is easy to tighten pad in installation process.
Generally speaking, the continuous inclined-plane of nut wedge shape inclined-plane and pad intermeshes and produces reverse mechanical force, the contact of nut wedge shape inclined-plane peak and the continuous inclined-plane of relative pad peak compresses mutually and contends with and can't become flexible when reverse start, the pressure that the rotation back produces makes pad and the pressurization of workpiece surface of contact groove, workpiece surface produces surperficial corresponding force towards the other side's depression, stop and slide, cannot not reach looseningly function, nut hexagonal opposite side bead breach is relative with the pad breach synchronous, need to rotate with the synchronous rotation of special tool(s), thereby do not reach anti-theft feature but have turn, and have and to repeat nonexpondable economic effect with common tool.
Advantage of the present invention is: because the braking between nut and the pad, the surface of workpiece combines with the pointed groove of pad, thereby can reach the effect of anti-loose anti-theft.
