Abstract
The invention relates to a nut. The nut comprises a nut body, a thread cavity and a rod body, wherein the thread cavity is formed in the nut body and the rod body extends downwards to form the rod body. The rod body comprises a butt joint cavity and an inner wall, wherein the butt joint cavity is formed in the rod body, the butt joint cavity is defined by the inner wall, and the butt joint cavity extends toward the rod body from the thread cavity and penetrates through the rod body. Internal threads are arranged on the inner wall, wherein the thread parameters of the internal threads are the same as the thread parameters of the thread cavity. A plurality of burrs extending downward are arranged on the nut body. The nut is simple in structure, the connection between a bolt and the nut can be strengthened, and the nut is prevented from looseness.
Description
Technical field
The present invention relates to a kind of nut.
Background technique
The nut generally using in the market generally comprises nut body, is formed on the intrinsic cavity of nut and is formed on the internal thread on the inwall of nut body.In use, only nut need to be tightened in above bolt.But, in some mechanical structures, in the process using due to device, easily produce vibration, thereby cause nut loosening, so, must frequent nut and bolt are checked, to prevent because nut becomes flexible or comes off, so brought a lot of inconvenience to production.
Summary of the invention
The object of the present invention is to provide being connected between a kind of simple in structure, strengthening stud and nut, can prevent the nut that nut is loosening.
For realizing aforementioned object, the present invention adopts following technological scheme: a kind of nut, the body of rod that comprises cap body, is formed on the intrinsic thread cavity of described cap, extends to form downwards from described cap body, the described body of rod comprises the docking chamber being formed in the described body of rod, the inwall that encloses formation described docking chamber, described docking chamber is extended and is run through the described body of rod towards the described body of rod from described thread cavity and forms, on described inwall, there is the internal thread identical with the thread parameter of described thread cavity, on described cap body, be provided with the some hangnails to downward-extension.
As a further improvement on the present invention, described cap body comprises diapire, and described hangnail is 30 ° of angle directions along described diapire and extends.
As a further improvement on the present invention, the diameter of the described body of rod is less than the diameter of cap body.
As a further improvement on the present invention, described thread cavity runs through described cap body.
As a further improvement on the present invention, described cap body is made by plastic material, or made by ferrous metal material, or alloy material is made.
The invention has the beneficial effects as follows: nut structure of the present invention is simple, by the body of rod and some hangnails are set on cap body, and in the body of rod, form docking chamber and the internal thread identical with the thread parameter of thread cavity, thereby when nut is coordinated with bolt, increase the junction surface of nut and bolt, bury underground in the object being fixed by hangnail simultaneously, being connected between strengthening stud and nut, prevent that nut is loosening.
Accompanying drawing explanation
Fig. 1 is the structural representation of nut in the specific embodiment of the invention.
Fig. 2 is the structural drawing that the nut of Fig. 1 is observed in another direction.
Fig. 3 is the flow chart of the preparation method of nut in the specific embodiment of the invention.
Embodiment
Refer to Fig. 1 and Fig. 2, the nut in one embodiment of the invention comprises cap body 1, is formed on thread cavity 2, the body of rod 3 extending to form from cap body 1 in cap body 1 downwards and is arranged on the some hangnails 4 on cap body 1.Cap body 1 comprises diapire 11 and the sidewall (not label) extending to form from diapire 11 and the roof 13 being oppositely arranged with diapire 11 downwards.Hangnail 4 is 30 ° of angle directions along diapire 11 and extends.In the present embodiment, this thread cavity 2 runs through cap body 1, and certainly, this nut can be also semi-enclosed, and one end of thread cavity 2 is open type, and the other end is closed.
The diameter of the body of rod 3 is less than the diameter of cap body 1.The body of rod 3 comprises the docking chamber 31 being formed in the body of rod 3 and encloses the inwall 32 that forms 31 docking chambeies.Docking chamber 31 is extended and is run through the body of rod 3 towards the body of rod 3 from thread cavity 2 and forms.On above-mentioned inwall 32, there is the internal thread identical with the thread parameter of thread cavity 2 33.
In the present embodiment, above-mentioned nut is made by plastic material, can certainly be made by ferrous metal material, or alloy material is made.
Referring to Fig. 1 to Fig. 3, is the preparation method of above-mentioned nut.The preparation method of this nut comprises S1 to S4 step.
S1: base material is provided.The number of this base material amount of providing provides depending on the required size of preparing nut.In the present embodiment, this base material is plastic material.
S2: by above-mentioned base material processing shape nut, the nut forming has cap body 1, be formed on the thread cavity 2 in cap body 1 and be formed on cap body 1 and diameter is less than the body of rod 3 of cap body 1 diameter.In this step, form described nut by the technique of molding and forming, and technique used is the common process step that forms nut in prior art, therefore be not described in detail at this.
S3: the internal thread 33 identical with the thread parameter of thread cavity 2 is set and forms hangnail 4 on cap body 1 on the interior formation docking of the body of rod 3 chamber 31 forming in above-mentioned S2 step, the inwall that docks chamber 31 in formation.
S4: the nut that described S3 step is formed carries out surface cleaning.
In S1 step, the base material of taking can also be metal or alloy material, and in S2 step, the nut that preparation forms also can adopt other prior aries to form.In the present embodiment, in S2 step, the thread cavity 2 forming runs through described cap body 1.Certainly, this nut can be also semi-enclosed, and one end of thread cavity 2 is open type, and the other end is closed.
In above-mentioned S2 step, the roof 13 that the cap body 1 forming comprises diapire 11, is oppositely arranged with diapire 11.In above-mentioned S3 step, the hangnail forming is 30 ° of directions along described diapire and extends.
Preparation method's technique of this nut is simple, easy to operate, by the nut with the body of rod 3 and hangnail 4 forming, and the setting internal thread 33 identical with the thread parameter of thread cavity 2 in the interior formation docking of this body of rod 2 chamber 31, on the inwall 32 that forms docking chamber 31, make coordinating by the nut of the prepared formation of the present invention the junction surface that increases nut and bolt with bolt, and hangnail 4 can be buried underground in the workpiece being fixed, thereby make nut more fastening with being connected of bolt.
In sum, above-mentioned nut structure is simple, by the body of rod 3 and some hangnails 4 are set on cap body 1, and in the interior formation docking of the body of rod 3 chamber 31 and the internal thread 33 identical with the thread parameter of thread cavity 2, thereby when nut is coordinated with bolt, increase the junction surface of nut and bolt, bury underground in the object being fixed by hangnail simultaneously, being connected between strengthening stud and nut, prevent that nut is loosening.
Although be example object, the preferred embodiment of the present invention is disclosed, but those of ordinary skill in the art will recognize, in the situation that not departing from by the disclosed scope and spirit of the present invention of appending claims, various improvement, increase and replacement are possible.
