Description

A kind of round nut

Technical field

The utility model is related to technical field of hardware, specially a kind of round nut.

Background technology

After six-sided nut on the market is tightened now, entire nut can expose, and not only influence the beauty of article, dew There are high points for the nut gone out, can also scratch human skin sometimes, be damaged to human body, there are some potential safety problemss.

Invention content

The purpose of this utility model is to provide a kind of round nut, the conventional nut to solve to propose in above-mentioned background exists Existing aesthetics difference and safety low problem when use.

To achieve the above object, the utility model provides the following technical solutions：A kind of round nut, including ontology, thread, Groove, Luo Bi, inner chamfer and outer chamfer, the ontology are connect with thread, and the ontology is the circular configuration of oxidation processes, described Ontology is the annulus of high intensity, and multigroup thread is arranged in the body interior, and the thread is the closely-pitched shape dextrorotation thread of inverted trapezoidal, The groove is connect with ontology, and the groove is the identical rectangular channel of four sizes, is uniformly distributed in body upper surface, the spiral shell Wall is connect with ontology, and the spiral shell wall surface is cross cut, and the inner chamfer is connect with thread, and the inner chamfer size occupies one A thread or so, the outer chamfer are connect with Luo Bi, and the size of the outer chamfer is equilateral chamfering, and right angle edge lengths are 2mm left It is right.

Preferably, the bulk material is 6062 alloys of high intensity, and essential element is magnesium and silicon.

Preferably, the spiral shell wall surface is covered with lines, is uniformly wrapped in body surface.

Compared with prior art, the utility model has the beneficial effects that：It can be twisted with hand, the round nut can be made just embedding Enter interior of articles, aesthetic greatly improves, it is thus also avoided that the high point of protrusion may cause human body the potential hazard scratched.

Description of the drawings

Fig. 1 is a kind of round nut structural schematic diagram of the utility model.

In figure：Ontology 1, thread 2, groove 3, spiral shell wall 4, inner chamfer 5, outer chamfer 6.

Specific implementation mode

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work The every other embodiment obtained, shall fall within the protection scope of the present invention.

Referring to Fig. 1, the utility model provides a kind of technical solution：A kind of round nut, including it is ontology 1, thread 2, recessed Slot 3, spiral shell wall 4, inner chamfer 5 and outer chamfer 6, the ontology 1 are connect with thread 2, and the ontology 1 is the round knot of oxidation processes Structure, the ontology 1 are the annulus of high intensity, and multigroup thread 2 is arranged in 1 inside of the ontology, and the thread 2 is the closely-pitched of inverted trapezoidal Shape dextrorotation thread 2, the groove 3 is connect with ontology 1, and the groove 3 is the identical rectangular channel of four sizes, is uniformly distributed in this 1 upper surface of body, the spiral shell wall 4 are connect with ontology 1, and 4 surface of spiral shell wall is cross cut, and the inner chamfer 5 connects with thread 2 It connects, 5 size of the inner chamfer occupies a thread 2 or so, and the outer chamfer 6 is connect with spiral shell wall 4, the size of the outer chamfer 6 For equilateral chamfering, right angle edge lengths are 2mm or so.

Operation principle：When needing to assemble or dismount round nut, using tools such as sleeve rotating seats, sleeve one end is equipped with Claw type convex block compatible with round nut groove 3, the sleeve other end and rotating seat one end pin-connect, circle is extend by tool Positioned in nut groove 3, and sleeve rotating is driven by pulling spanner, so that round nut be tightened by thread 2 or It screws out, because ontology 1 is circular configuration, can completely be embedded into circular threaded hole, avoid round nut exposed, promoted beautiful Degree and safety, the lines on 4 surface of spiral shell wall can effectively improve frictional force, and hand is facilitated to twist, the setting of inner chamfer 5 and outer chamfer 6, Guiding function is played when being packed into, aspect round nut is screwed into threaded hole.

While there has been shown and described that the embodiments of the present invention, for the ordinary skill in the art, It is appreciated that can these embodiments be carried out with a variety of variations in the case where not departing from the principles of the present invention and spirit, repaiied Change, replace and modification, the scope of the utility model are defined by the appended claims and the equivalents thereof.
