Abstract
The invention relates to a nut structure with taper skewed teeth, which comprises a nut head and a nut post, wherein the nut post is a tapered shape, and a knife withdrawing groove is arranged on the root part of the nut post; the tapered surface of the nut post is provided with the skewed teeth; the nut head is in a hexagonal shape; the middle of the nut post is provided with a blind hole with threads; and the middle of the nut post is provided with the through hole with the threads. By adopting the above structure, after the nut post is installed, the push-out resistance and the torque resistance of the components are more excellent, the dropping phenomenon of the nut post can be greatly reduced, the valuables can be effectively protected against dropping, and the service life of the components after being connected with each other can be increased.
Description
Technical field
The present invention relates to a kind of nut structure of hardware industry, especially relate to a kind of nut structure that has the tapering helical teeth.
Background technique
Many on the market links that are used for panel beating, thin plate, cabinet, rack, automobile etc., the Nut column that all adopts is columniform, the barrel nut post is when clamping onboard the time; Anti-release power and torque resistant do not reach certain requirement, after repeatedly using, take place loosening easily; Also might drop, after becoming flexible or dropping, the part that is connected on the Nut column will be unstable; Might cause the valuables damage of dropping, cause unnecessary loss.
Summary of the invention
Technical problem to be solved by this invention provides a kind ofly has the more nut structure that has the tapering helical teeth of outstanding properties in anti-release power and torque resistant.
The present invention solves the technological scheme that its technical problem takes: a kind of nut structure that has the tapering helical teeth, comprise nut head and Nut column, and described Nut column is taper, is provided with tool withdrawal groove at the root of Nut column.
For the anti-release power that strengthens Nut column and the performance of torque resistant, the conical surface of described Nut column is provided with oblique annular knurl tooth.
Connecting other part for ease, is screwed blind hole in the middle of the described Nut column, blind threaded its effect to sealing; In the middle of the perhaps described Nut column is screwed through hole.
The invention has the beneficial effects as follows: adopt after the said structure; After Nut column was installed, the anti-release power of part and the performance of torque resistant were better, and the phenomenon that Nut column drops significantly reduces; Can effectively protect valuables to drop, increase each part and connected working life afterwards.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the left view of Fig. 1 of the present invention.
Among the figure: 1, nut head; 2, Nut column; 3, oblique annular knurl tooth; 4, tool withdrawal groove; 5, through hole.
Embodiment
A kind of nut structure that has the tapering helical teeth as depicted in figs. 1 and 2 comprises nut head 1 and Nut column 2, and described Nut column 2 is for taper, is provided with tool withdrawal groove 4 at the root of Nut column 2; The conical surface of described Nut column 2 is provided with oblique annular knurl tooth 3; Described nut head 1 is a hexagon; In the middle of the described Nut column 2 is screwed through hole 5.
When producing, device has seal request, also can produce the Nut column centre and is the structure of screwed blind hole.
When operation is installed; The part that at first will have the oblique annular knurl tooth 3 of tapering is put on the sheet material that has the hole, and the hole on the sheet material is slightly larger than the fore-end of the oblique annular knurl tooth 3 that has tapering, and the rear end part that has the oblique annular knurl tooth 3 of tapering is slightly larger than the diameter of plate hole; The Nut column 2 that has tapering mainly plays leading role; Oblique annular knurl tooth 3 parts that will have a tapering through press machine are pressed in the preparatory discharge hole of thin plate and make the periphery in hole produce plastic deformation, and crushed element is squeezed in the tool withdrawal groove 4 of the nut structure that has the tapering helical teeth, and nut is riveted tightly on thin plate; Thereby on thin plate, constitute effectively fixing internal thread, the convenient part that connects other.
