Abstract
The utility model relates to a riveting nut, which comprises threads and knurls. At least two pressure points are arranged at the bottom threads of the riveting nut and are uniformly distributed on periphery of the bottom of the riveting nut; and at least one knurl is arranged and can be replaced by a lateral tangent plane. When tightening a bolt and the riveting nut, the pressure points damage the threads of the bolt, so as to avoid relative movement between the bolt and the riveting nut during the high-speed operation of a machine.
Description
Technical field
The utility model relates to a kind of nut, especially relates to a kind of self-clinching nut.
Background technique
Self-clinching nut is a kind of nut that is applied on thin plate or the panel beating, and profile is rounded, and an end has emboss knobs and guiding groove.Its principle is to be pressed in the preset holes of panel beating by emboss knobs, generally speaking the aperture of preset holes is slightly less than the emboss knobs of self-clinching nut, the periphery that the colored tooth of self-clinching nut is clamp-oned make the hole in the plate by pressure produces plastic deformation, and deformations is squeezed into guiding groove, thereby produces the effect of locking.When screw bolt and nut cooperates, the machine high-speed motion produces and to jolt, and causes self-clinching nut and bolt to rotate, and makes bolt not on preposition.
Summary of the invention
It can be the self-clinching nut that bolts and nuts do not produce relative movement that technical problem to be solved in the utility model provides a kind of.
The technical scheme in the invention for solving the technical problem is: a kind of self-clinching nut, comprise screw thread and flower tooth, and at the bottom thread place of self-clinching nut pressure point is arranged.
In order to make pressure point can thoroughly destroy screw thread, described pressure point has two at least.
Destroy after the screw thread in order to make, lateral deviation not when tightening self-clinching nut, described pressure point is distributed on the circumference of self-clinching nut bottom surface.
For self-clinching nut is not rotated on steel plate, described colored tooth can replace with the side tangent plane, and has one at least.
Adopt after the said structure, when bolting on self-clinching nut, pressure point has destroyed the screw thread of bolt, and bolt and self-clinching nut just can not produce relative movement when the machine high-speed motion like this.

Fig. 3 is an another kind of embodiment's of the present utility model worm's eye view;
Fig. 4 is the plan view of the another kind of structure of the utility model;
1, screw thread 2, flower tooth 3, pressure point 4, side tangent plane
Embodiment
Fig. 1, Fig. 2 and a kind of self-clinching nut shown in Figure 3 comprise screw thread 1 and flower tooth 2, at the bottom thread place of self-clinching nut pressure point 3 are arranged.Pressure point 3 is to make unnecessary metal at flank of thread outstanding metal be arranged by the punching press to the bottom surface, described pressure point 3 has two at least, described pressure point 3 is distributed on the circumference of self-clinching nut bottom surface, the effect of pressure point 3 is the screw threads that destroy bolt, make bolt when the machine high-speed motion and self-clinching nut do not produce relative movement.
Colored tooth 2 shown in Figure 4 can replace with side tangent plane 4, and has one at least, and the effect of flower tooth 2 and side tangent plane 4 is to prevent that self-clinching nut from rotating in steel plate.
Self-clinching nut is pressed in the steel plate by press, because colored tooth 2 or side tangent plane 4 are arranged, self-clinching nut just is fixed on steel plate and has suffered; Bolt is when cooperating with self-clinching nut, and when the screw thread of bolt ran into pressure point 3, pressure point 3 was thread damage, makes bolt and the self-clinching nut can relative movement.
All equivalences of being done according to the utility model content change or modify, and all should be encompassed within the protection domain of the present utility model.
Claims (4)
