Abstract
The utility model relates to a clamp nut. The nut is provided with an outer hexagon and an inner threaded hole which is axially through. A flange is formed on one axial end face of the nut, and the flange and the outer hexagon are connected into a whole. The diameter of the flange is larger than the length of the diagonal line of the outer hexagon. A groove encircling the inner threaded hole is formed in the axial end face, in contact with a clamped piece, of the flange. A plurality of three-edge teeth are evenly distributed on the axial end face, locating between the groove and the outer circumference of the flange and making contact with the clamped piece, of the groove. The included angle between the bottom face of each three-edge tooth and a first edge is 80-85 degrees, the included angle between the bottom face of each three-edge tooth and a second edge is 10-12 degrees, and the included angle between the bottom face of each three-edge tooth and a third edge is 5-8 degrees. The clamp nut is easy to manufacture, convenient to use and extensive in universality.
Description
Technical field
The utility model relates to fastening piece and manufactures field, particularly a kind of tightening nut.
Background technique
Nut is a kind of and screw flight is combined together the fastenings commonly used played the role of fastening.If nut is the environment in vibrations for a long time, easily occur becoming flexible, can not reach fastening purpose.In order to prevent nut loosening, generally when mounting nuts, need increase check washer or use abnormal screw thread etc., so make fastenings quantity increase, the abnormal screw thread processed complex, versatility is restricted, and need special-purpose instrument to install or dismounting, make the user cost of nut high, using scope is restricted.
Summary of the invention
The purpose of this utility model is for the deficiencies in the prior art, and a kind of tightening nut is provided, and it manufactures simple, and easy to use, versatility is wide.
The technical solution of the utility model is: a kind of tightening nut, the interior threaded hole that nut is provided with outer-hexagonal and axially runs through, one axial end of nut forms the flange be connected as a single entity with outer-hexagonal, the diameter of this flange is greater than the outer-hexagonal catercorner length, the axial end that described flange contact is compacted is provided with the groove around interior threaded hole, this groove is laid with several Rhizoma Sparganii teeth on the axial end of compacted of the contact between the flange excircle, angle between the bottom surface of described Rhizoma Sparganii tooth and the first seamed edge is 80～85 °, and the angle between the second seamed edge is 10～12 °, and the angle between the 3rd seamed edge is 5～8 °.
Described the 3rd seamed edge is curve.
The degree of depth of described groove is 0.2～0.5 ㎜.
Adopt technique scheme: the axial end that the flange contact is compacted is provided with the groove around interior threaded hole, this groove is laid with several Rhizoma Sparganii teeth on the axial end of compacted of the contact between the flange excircle, angle between the bottom surface of described Rhizoma Sparganii tooth and the first seamed edge is 80～85 °, and the angle between the second seamed edge is 10～12 °, and the angle between the 3rd seamed edge is 5～8 °.The groove arranged on axial end has reduced axial end and compacted 's area of contact, increased axial end to the pressure of compacted, make the Rhizoma Sparganii tooth be positioned on axial end easily block and be absorbed in compacted, article three, seamed edge is different from the angle of Rhizoma Sparganii tooth bottom surface, it is the slanted angle difference of three sides of Rhizoma Sparganii tooth, the resistance be subject to while tightening tightening nut is less, and the resistance be subject to while unscrewing tightening nut is larger, makes this tightening nut can not occur becoming flexible because of Long-term Vibration.
Below in conjunction with accompanying drawing explanation and embodiment, be further described.
The accompanying drawing explanation
Fig. 1 is the structural representation of looking up of the present utility model;
The A-A that Fig. 2 is Fig. 1 is to sectional view;
The P place partial enlarged drawing that Fig. 3 is Fig. 1;
Fig. 4 is plan structure schematic diagram of the present utility model.
In accompanying drawing, 1 is interior threaded hole, and 2 is flange, and 3 is groove, and 4 is the Rhizoma Sparganii tooth, and 4a is the first seamed edge, and 4b is the second seamed edge, and 4c is the 3rd seamed edge, and 5 is crown.
Embodiment
Referring to Fig. 1 to Fig. 4, a kind of tightening nut, the interior threaded hole 1 that nut is provided with outer-hexagonal and axially runs through, an axial end of nut forms the flange 2 be connected as a single entity with outer-hexagonal, the diameter of this flange 2 is greater than the outer-hexagonal catercorner length, and the position that flange 2 is connected with the nut outer-hexagonal is curved surface.The axial end that described flange 2 contact is compacted is provided with the groove 3 around interior threaded hole 1, the degree of depth of described groove 3 is 0.2～0.5 ㎜, the present embodiment, the degree of depth of groove 3 is 0.3 ㎜, this groove 3 is laid with several Rhizoma Sparganii teeth 4 on the axial end of compacted of the contact between the flange excircle, the present embodiment, the quantity of Rhizoma Sparganii tooth 4 is 24, the Rhizoma Sparganii tooth is helical teeth, the groove arranged has reduced axial end and compacted 's area of contact, effectively increase the Rhizoma Sparganii tooth to the pressure of compacted, make the crown 5 of Rhizoma Sparganii tooth more easily block and be absorbed in the surface of compacted, after Rhizoma Sparganii tooth card is absorbed in the surface of compacted, groove also plays the effect of stepping down.Angle between the bottom surface of described Rhizoma Sparganii tooth 4 and the first seamed edge 4a is 80～85 °, and the angle between the second seamed edge 4b is 10～12 °, and the angle between the 3rd seamed edge 4c is 5～8 °, seamed edge is different from the angle of bottom surface, therefore length is also different, wherein the length of the 3rd seamed edge 4c is the longest, the length of the first seamed edge 4a is the shortest, the 3rd seamed edge 4c is curve, the second seamed edge 4b, the 3rd seamed edge 4c, the inclination minimum on crown 5 inclined-planes, place, be that its gradient is the most slow, the first seamed edge 4a, the second seamed edge 4b, the inclination maximum on crown 5 inclined-planes, place, it is its gradient steepest, the first seamed edge 4a, the 3rd seamed edge 4c, the inclination on crown 5 inclined-planes, place is larger, its gradient is steeper.
During use, the inclined-plane the most slow along the Rhizoma Sparganii tooth gradient with spanner rotates fastening nut, after nut screwing clamping puts in place, crown 5 cards are absorbed in compacted surface, because other two surface slopes of Rhizoma Sparganii tooth are steeper, the nut steering resistance is larger, and nut is in the situation that vibration is difficult to turn round loosening.
