Abstract
The utility model relates to an efficient torque type screw bolt with a nylon embedded component, which can resist impact loads and variable loads, and the utility model is composed of a screw bolt, wherein the end part of the screw bolt is provided with an embedded groove which makes the end head of the screw bolt divided into at least two equal segments and a nylon embedded component is embedded into the embedded groove. The utility model not only can be matched with screw nuts and screw holes with the same specification, but also can efficiently have the functions of preventing looseness and locking, can have the advantages of novel structure, simple manufacture and good effect of looseness prevention and can be used under the action of strong impact loads and the variable loads.
Description
The utility model belongs to a kind of fastening piece, relates in particular to the effective torque type nylon inserts bolt of a kind of resistance to shock loads, varying load.
In mechanical field, particularly run up, the train of sharp pounding, automobile, aircraft, tank, steamer, tractor, motor etc., under strong impulsive load, varying load effect, fastening piece often becomes flexible, comes off, causes mechanical failure easily, even vehicle overturns, accidents such as fatal crass, and equipment property and human life's safety in serious threat.The common standard part leans on spring washer that the top spiral shell is emitted in mechanical industry and gives tight back generation lock function, but be unable to undergo to run up, the long impulsive load of judder makes fastened surface and fastener itself, is developed into plastic deformation and is produced the gap and take place loosening by resiliently deformable.Alternate load can make loosening fastening piece deform or cut off.The generation torque force that runs up, loosening fastening piece torque resistant force coefficient no better than zero, the loose or dislocation problem that how to solve fastening piece has become the important topic of mechanical industry.The high strength of fastening piece, the multi-functional inexorable trend that become.
The purpose of this utility model is to overcome the deficiencies in the prior art and provides a kind of not only can the pairing with nut, the screw of same specification to use, and can also play the effective torque type nylon inserts bolt of locking lock function effectively.
The purpose of this utility model is achieved in that and has in the bolt end the bolt end caulking groove of halves at least, be embedded with the nylon inserts in caulking groove.The caulking groove groove width is equal to or greater than bolt pitch, embeds the nylon inserts that matches again, forms effective torque type nylon inserts bolt.This bolt and same specification nut (screw) match when fastening, the nylon inserts is under the effect of precession external force, by the nut extruding resiliently deformable being taken place forms and the synchronous screw thread of bolt, and overcome friction is finished fastening smoothly, finish fastening back frictional force disappears thereupon, only remaining nylon inserts keeps corresponding expanding force to nut, and this expanding force is invariable.Must overcome the nylon inserts during derotation could screw out the frictional force that the nut expanding force is produced.
The utility model not only can use with nut, the screw pairing of same specification, can also play locking lock function effectively, has novel structure, makes the advantage simple, that anti-loosing effect is good.
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 installs structural representation behind the nylon inserts for of the present utility model.
Fig. 3 is a nylon inserts schematic representation of the present utility model.
Fig. 4 is a nylon insert side view of the present utility model.
Shown in Fig. 1,2,3,4, the utility model is made of bolt 1, has in the bolt end the bolt end caulking groove 2 of halves at least, is embedded with nylon inserts 3 in caulking groove.The caulking groove 2 that for example bolt end is divided into quarter can be made a call to a blind hole at the bolt end center earlier, is divided into four caulking grooves 2 again, and hole and caulking groove deep equality are embedded with nylon inserts 3 in caulking groove.Described bolt can be double-screw bolt and heterotypic bolt.Described caulking groove 2 groove widths are equal to or greater than bolt pitch.The diameter of described inserts is less than the big footpath of bolt, greater than the path of bolt.This bolt and same specification nut (screw) match when fastening, the nylon inserts is under the effect of precession external force, by the nut extruding resiliently deformable being taken place forms and the synchronous screw thread of bolt, and overcome friction is finished fastening smoothly, finish fastening back frictional force disappears thereupon, only remaining nylon inserts keeps corresponding expanding force to nut, and this expanding force is invariable.Must overcome the nylon inserts during derotation could screw out the frictional force that the nut expanding force is produced.
