Abstract
The utility model discloses a fastener, in particular to an exterior axial component multilateral body type anti-disassembly nut for fastening field devices, comprising a nut body, wherein the nut body has a side face of an inner hole provided with a groove which is provided inside with balls (5) for fastening; the utility model is characterized in that the exterior axial component of the nut body is processed with a multilateral body(1) for the twisting of a wrench. The thickness of the surface of the nut where the multilateral body is processed, that is, the thick ness of the hexagonal part is smaller than that of the hexagonal part into which the nut is completely processed, when the rotating torque of screwing off is overlarge, the slipping effect is occurred between the outer surface of the nut and the wrench, thereby effectively preventing the fastener from being disassembled or damaged; as a result, the utility model is safe and reliable.
Description
Technical field
The utility model relates to a kind of fastening piece, and particularly a kind of appearance axial component polyhedral formula anti-assembling nut is mainly used in the fastening of open-air various facilities, as electric power facility, road equipment, communications facility etc., prevent loosening or facility stolen.
Background technique
Open-air various facilities fastening extremely important, its fastening piece is if any the loosening loss that can cause facility self damage and other people personal injury or property, also easily by other people theft, particularly electric power, communications facility, as have an accident or stolen, can cause heavy economic losses.In order to address the above problem, the fastening piece of at present fixing above-mentioned facility has all been selected anti-assembling nut for use, its structure is to be processed with one or many grooves at the endoporus place of nut body, in groove, be provided with ball and block piece, be provided with elastic component between ball and block piece, fixedly connected between block piece and the nut body, the diameter of ball is slightly less than or equals the innermost degree of depth of groove, the appearance of nut body is the hexagonal shaped shape, is convenient to twist with spanner.When on bolt, during precession, rubbing because elastic component leans the screw thread of ball and bolt with spanner, make ball be pressed towards groove than the depths, do not influence the precession of nut, be screwed into and can play fastening effect when certain pretightening force is arranged.As swivel nut round about,, ball is squeezed between the screw thread of nut and bolt under frictional force action because elastic component leans ball, rotating force round about is big more, and the strength of squeezing is big more, and nut can not be removed, this nut had both prevented loosening, prevented that again other people from unloading.But the nut of this structure of using is because its appearance all is processed into six sides that spanner is convenient to twist at present, when using than the spanner of long handle when unloading the rotation of lower nut direction, because of the moment of torsion of spanner big, the appearance of nut all is processed into the hexagonal shaped shape, causes lifting surface area big, and the hexahedron surface is unlikely skids with respect to spanner, so twist off bolt easily or destroy screw thread, finally make fastening piece lose fastening effect, safety reliability is poor, can not accomplish thoroughly anti-unloading.
Summary of the invention
The purpose of this utility model provides a kind of when to unloading lower nut direction moment of rotation when excessive; skidding can take place between nut appearance and the spanner, protect that this fastening piece is not destroyed, safe and reliable appearance axial component polyhedral formula anti-assembling nut, overcome the deficiencies in the prior art.
Appearance axial component polyhedral formula anti-assembling nut of the present utility model, it comprises nut body, place, endoporus side at nut body is provided with groove, is provided with anti-unloading with ball 5 in the groove, and it is characterized in that: the appearance axial component of described nut body is processed with the polyhedral that is used for the spanner twisting.
Appearance axial component polyhedral formula anti-assembling nut of the present utility model is provided with block piece 3 in the wherein said groove, the diameter of ball 5 is slightly less than or equals the innermost degree of depth of groove, is provided with elastic component 4 between ball 5 and block piece 3,
Appearance axial component polyhedral formula anti-assembling nut of the present utility model, the appearance of wherein said nut body axially other parts are processed as the cylindrical body 2 that links to each other with polyhedral 1, and the diameter of cylindrical body 2 is equal to or less than distance between the opposite side of polyhedral 1.
Appearance axial component polyhedral formula anti-assembling nut of the present utility model, because the place, endoporus side at nut body is provided with groove, be provided with anti-unloading in the groove with ball 5, the appearance axial component of described nut body is processed with the polyhedral that is used for the spanner twisting, make the nut appearance be processed with polyhedron promptly the thickness that divides of six quadrate parts than all be processed in the prior art polyhedron promptly six sides' thickness reduce, when to unloading lower nut direction moment of rotation when excessive, produce skidding between nut appearance and the spanner, promptly the moment of torsion that can bear between six sides and the spanner is less than the anti-moment of torsion that unloads of nut itself.Prevented effectively that fastening piece from being unloaded or destroyed, safe and reliable.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is a schematic top plan view shown in Figure 1;
Fig. 3 is that schematic representation is looked on a left side shown in Figure 1;
Fig. 4 is that K shown in Figure 1 is to schematic representation.
Embodiment
As shown in the figure: 1 is polyhedral, and the appearance of polyhedral 1 is hexagonal shaped shape or square shape, is convenient to common spanner twisting.2 is cylindrical body, and cylindrical body 2 is a linking body structure with polyhedral 1, and the diameter of cylindrical body 2 is less than or equal to the distance between the opposite side of six sides or tetragonal body.Its appearance of the nut of this structure can all be six sides or cubic thickness less than nut appearance in the prior art with six sides or the cubic thickness of spanner twisting, cut down the moment of torsion that six sides or four directions can bear spanner, when to unloading lower nut direction moment of rotation when excessive, produce skidding between nut appearance and the spanner, promptly the moment of torsion that can bear between six sides or four directions and the spanner is less than the anti-moment of torsion that unloads of nut itself.Prevented effectively that fastening piece from being unloaded or destroyed, safe and reliable.Be processed with screw thread on the endoporus side of the nut body that forms by polyhedral 1 and cylindrical body 2.Be processed with the groove of degree of depth gradual change at the place, endoporus side of nut body, ball 5 and block piece 3 are housed in this groove, and the diameter of ball 5 is slightly less than or equals the innermost degree of depth of groove, and block piece 3 is that cylinder is shaft-like, and and nut body between for the riveted joint, block piece 3 is fixed on the nut body.Between ball 5 and block piece 3 elastic component 4 is housed, elastic component 4 is a spring.In groove, be filled with the elastic gum of adhesion ball 5 and/or elastic component 4.Elastic gum can be the high elasticity glue of existing silicon sealant or industrial use, and existing adhesion function has elasticity again.Elastic gum can be full of groove, also can fill one or more, as long as ball 5 and/or elastic component 4 are positioned in the groove on the nut body, prevents to cause nut to scrap phenomenon coming off with generation ball 5 before bolt cooperates and elastic component 4.
