Abstract
The invention discloses a double-slotted self-locking nut. The double-slotted self-locking nut comprises a nut body, wherein a convex cylindrical object is arranged on one end surface of the nut body; a threaded hole which is interlinked with the threads on the nut body is formed in the cylindrical object; two symmetric slots which are vertical to the axis of the cylindrical object are formed in a cylinder of the cylindrical object; the depths of the slots are greater than the semicircle of the cylindrical object; the openings of the slots are extruded to deform along the axis of the cylindrical object; a butterfly-shaped gasket is arranged on the other end surface of the nut body; and a plurality of radial beads are arranged on the end surface of the gasket. When the double-slotted self-locking nut is screwed, the locking force is uniformly distributed on the threads and the meshing is tighter, so that the double-slotted self-locking nut is suitable for the application with more severe vibration and impact; through the setting of the butterfly-shaped gasket on the end surface, the anti-loose self-locking effect is more outstanding; and the self-locking nut is simple to mount, reusable, more convenient to dismount and more efficient.
Description
Technical field
The present invention relates to a kind of structure connecting securing member, belong to field of mechanical technique, more particularly to a kind of double; two fluting self-locking nuts.
Background technology
In being connected with each other of connector, threaded is very general and conventional one, and the anti-loose method that current threaded fastener connects is divided into three basic forms of it: the locking and increasing friction force of non-removable locking, mechanical fixed part locking.Non-removable locking be that a kind of employing welds, bonds or rushes the modes such as a riveted joint and changes into non-dismountable threaded anti-loose method by detachably threaded, its shortcoming is that threaded fastener can not be reused;The locking of mechanical fixed part is to utilize mechanical fixed part to make between screw element and connected piece or fix between screw element and screw element and lock, loosening to prevent, shortcoming is to increase the weight being fastenedly connected, and manufactures and installs trouble, motor-driven installation can not be carried out, thus relatively costly;Increasing friction force locking utilizes to be increased between screw thread or the frictional force of bolt (screw) head and nut end face or simultaneously increase both method of frictional force to reach locking purpose, and this anti-loose method is poorer than the reliability of above-mentioned first two method.The locking mode being connected by between current parts has double nut assembly method, cone pressure holds locking clamp device tightly, bolt adds split pin mode, plain nut adds stop washer mode, plain nut adds the mode of plain cushion spring washer etc..Double nut assembling makes screw thread between two height of nuts produce small elastic deformation to obtain additional friction force and locking, but this kind of mode needs two nuts every time, and workload is big, and workpiece weight increases.Cone pressure holds locking clamp device tightly to be needed to tighten mother nut and locking nut two parts part, and workload is big.Bolt adds split pin mode needs assembled in situ split pin, and workload increases, and encounter problems dismounting inconvenience.Plain nut adds stop washer mode for the angle of packing ring and highly desirable field operation, is not easy to control.The mode anti-loosing effect that plain nut adds plain cushion spring washer etc. is bad.
Summary of the invention
In order to overcome the deficiencies in the prior art, the invention provides a kind of double; two fluting self-locking nut.
The present invention is achieved by the following technical solutions: a kind of double; two fluting self-locking nuts, including nut body, an end face of described nut body is provided with the column of protrusion, column is provided with the screwed hole communicated with the screw thread on nut body, being provided perpendicular to the groove of column axis on the cylinder of column, the degree of depth of described groove is more than the semicircle of column.
In such scheme, described groove be set to two and on column lateral symmetry, two grooves are along the axis misalignment of column.
In such scheme, optimizing structure as one, the notch of described groove is along the axis crimp of column.
In such scheme, another end face of described nut body is provided with packing ring, described packing ring and nut body activity riveted joint.
In such scheme, the internal diameter of described packing ring is provided with annular protrusion, and the end face of described nut body is provided with the seam of protrusion, and seam outward flanging blocks described annular protrusion.
In such scheme, described packing ring is butterfly gasket, and the end face of packing ring is provided with radial a plurality of fin.
Compared with prior art, it provides the benefit that this pair of fluting self-locking nut:
1, the present invention double; two fluting self-locking nut arranges symmetric double fluting, and coupling mechanism force can be made to be evenly distributed on screw thread, makes engagement tightr, is suitable for vibration and impacts more violent application.
2, the present invention double; two fluting self-locking nut utilizes the tension force of butterfly gasket to be threaded offer locking effect, makes locking self-locking effect more remarkable.
3, the present invention double; two fluting self-locking nut is installed simple, reusable, dismounts more convenient, more efficient.

Detailed description of the invention
The present invention double; two fluting self-locking nut is further described with specific embodiment below in conjunction with accompanying drawing:
Fig. 1 is the structural representation of the present invention double; two fluting self-locking nut, Fig. 2 is the A-A sectional view of Fig. 1, in figure, this pair of fluting self-locking nut includes nut body 1, a right side of nut body 1 is provided with the column 2 of protrusion, being provided with the screwed hole communicated with the screw thread on nut body 1 in column 2, the cylinder of column 2 is provided perpendicular to the groove 3 of column axis, the degree of depth of groove 3 exceedes the semicircle of column.Groove 3 be set to two and on column 2 upper and lower lateral symmetry, two grooves 3 stagger along about the axis of column 2, and the notch of groove 3 is along the axis crimp of column 2.The notching construction of this double; two fluting self-locking nut can realize splendid anti-loosing effect, and its locking slot forms through Precision Machining, makes female thread produce certain pitch difference.When bolt screws in, female thread replys original pitch, and elastic deformation occurs, and internal and external threads is tightly engaged by the elastic force of generation, makes nut firmly be self-locking on bolt.
Fig. 3 is the another kind of structural representation of double; two fluting self-locking nut, and Fig. 4 is the left view of Fig. 3, and Fig. 5 is the partial enlarged drawing at B place in Fig. 3.In figure, being additionally provided with butterfly gasket 4 on the left side of nut body 1, the internal diameter of butterfly gasket 4 is provided with annular protrusion 6, and the right side of nut body 1 is provided with the seam 7 of protrusion, seam 7 outward flanging blocks annular protrusion 6, and the end face of butterfly gasket 4 is provided with radial a plurality of fin 5.In the process that double; two fluting self-locking nuts screw, the end face of butterfly gasket 4 is pressed on the surface of fastened part without rotating.
This double; two fluting self-locking nut can make coupling mechanism force be evenly distributed on screw thread when screwing, make engagement tightr, it is suitable for vibration and impacts more violent application, the setting of end face butterfly gasket makes locking self-locking effect more remarkable, and this pair of fluting self-locking nut is installed simple, reusable, dismount more convenient, more efficient.
