Description
Technical Field
The utility model relates to a nut component technical field especially relates to a high strength nut component.
Background
The nut component consists of a bolt and a nut, the nut is a nut, and is a part which is screwed together with the bolt or a screw rod and used for fastening, and an element which is necessary for all production and manufacturing machines is divided into carbon steel, stainless steel and nonferrous metal according to different materials;
when the nut assembly in the existing market mountain is used for fastening an object, the nut can break due to abrasion along with the action of external force after a period of time, and therefore the fastening of a workpiece is not guaranteed.
SUMMERY OF THE UTILITY MODEL
The utility model aims at solving the defects existing in the prior art and providing a high-strength nut component.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
designing a high-strength nut assembly, which comprises a nut and a bolt, wherein the nut is in threaded connection with the outer side of the bolt, chamfer angles are arranged on the outer sides of the upper end surface and the lower end surface of the nut, the diameter of the nut is matched with that of the upper end of the bolt, and a protection mechanism is further arranged on the outer side of the nut;
protection machanism includes the sleeve pipe and sets up the external screw thread section in the nut outside, and the external screw thread section is vertical setting, internal thread section has been seted up to sheathed tube inboard, the sleeve pipe box is established in the outside of nut, and intermeshing between external screw thread section and the internal thread section.
Preferably, the upper end face of nut evenly welds has a plurality of arc pieces that the size is the same, and is a plurality of the arc setting is personally submitted to the upper end of arc piece, and a plurality of arc pieces are annular array and distribute.
Preferably, the upper end surface of the bolt is plated with a wear-resistant layer, and the wear-resistant layer is a zinc-nickel alloy layer.
Preferably, a plurality of round holes are evenly arranged on the lower end face of the nut, and the round holes are distributed in an annular array.
The utility model provides a pair of high strength nut component, beneficial effect lies in: this high strength nut assembly can guarantee that the nut can not appear because of wearing and tearing lead to the cracked condition to appear after a period, the effectual fastness that has improved nut assembly to the object, the security that simultaneously extra-high part is fixed.
Drawings
Fig. 1 is a front view of a high-strength nut assembly according to the present invention.
Fig. 2 is a top view of the high-strength nut assembly according to the present invention.
In the figure: the bolt comprises a nut 1, an arc-shaped block 2, a bolt 3, a wear-resistant layer 4, a sleeve 5, an internal thread section 6, a round hole 7 and an external thread section 8.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.
Example 1
Referring to fig. 1-2, a high strength nut assembly, including nut 1 and bolt 3, nut 1 threaded connection is in the outside of bolt 3, the up end of nut 1 and the terminal surface outside down all are provided with the chamfer angle, the up end of bolt 3 has plated wear-resisting layer 4, and wear-resisting layer 4 specifically is the zinc-nickel alloy layer, the setting of chamfer angle can prevent that nut 1 from the condition of stress concentration appearing, the intensity of nut 1 has been improved, the zinc-nickel alloy layer possesses fine stand wear and tear simultaneously, high temperature resistant and corrosion-resistant characteristics to prolong the life of bolt 3.
The diameter of the nut 1 is matched with the diameter of the upper end of the bolt 3, and a protection mechanism is arranged on the outer side of the nut 1; protection machanism includes sleeve pipe 5 and sets up the external screw thread section 8 in the nut 1 outside, and external screw thread section 8 is vertical setting, and internal thread section 6 has been seted up to sleeve pipe 5's inboard, and the sleeve pipe 5 cover is established in the outside of nut 1, and intermeshing between external screw thread section 8 and the internal thread section 6, overlaps the fixed cover of sleeve pipe 5 in the outside of nut 1, and the effectual protection effect to nut 1 that plays can prevent simultaneously that cracked condition from appearing in nut 1 under the exogenic action.
Example 2
Referring to fig. 1-2, as another preferred embodiment of the utility model, the difference with embodiment 1 lies in, the up end of nut 1 evenly welds has a plurality of arc pieces 2 that the size is the same, the arc setting is personally submitted to the upper end of a plurality of arc pieces 2, and a plurality of arc pieces 2 are the annular array and distribute, arc piece 2 can make nut 1 when fixed to the part, through a plurality of arc pieces 2 and part mutual contact, thereby can effectually reduce area of contact, the pressure between nut 1 and the part has been increased, make fixed effect promote.
Example 3
Referring to fig. 1-2, as another preferred embodiment of the present invention, the difference from embodiment 1 or embodiment 2 is that a plurality of round holes 7 have been evenly opened on the lower end surface of nut 1, and a plurality of round holes 7 are distributed in an annular array, when disassembling nut 1, a wrench is often used to disassemble, but the wrench contacts with the outer surface of nut 1, and will wear the outer thread section 8 outside nut 1, so that the nut 1 needs to be disassembled by matching round holes 7 with the wrench.
The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
