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 external threads, wherein the butt joint cavity is formed in the rod body, the external treads are formed on the outer ee of the rod body, the rotation direction of the external threads is the same as that the thread cavity, and the butt joint cavity extends toward the rod body from the thread cavity and penetrates through the rod body. The diameter of the rod body is smaller than the diameter of the nut body. The nut is simple in structure, the nut body is provided with the butt joint cavity and the externally-threaded rod body, the diameter of the rod body is smaller than the diameter of the nut body, and therefore when the nut is matched with a bolt, the rod body can be buried in a fixed workpiece, the nut is connected with the workpiece in a threaded mode, connection between the 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 a kind of simple in structure, can strengthening stud and nut between be connected, 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 on the docking chamber being formed in the described body of rod and the outer rim that is formed on the described body of rod and the outside thread identical with the rotation direction of described thread cavity, described docking chamber is extended and is run through the described body of rod towards the body of rod from described thread cavity and forms, and the diameter of the described body of rod is less than the diameter of cap body.
As a further improvement on the present invention, the described body of rod also comprises the inwall that encloses formation described docking chamber, has the internal thread identical with the thread parameter of described thread cavity on described inwall.
As a further improvement on the present invention, described outside thread is covered with the whole body of rod.
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 nut 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, there is docking chamber and the externally threaded body of rod by arranging on nut body, and the diameter of this body of rod is less than the diameter of cap body, when nut is coordinated with bolt, this body of rod also can be buried underground in the workpiece being fixed, and between this nut and workpiece, form and be threaded, thus can strengthening stud and nut between be connected, 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 the thread cavity 2 in cap body 1, the body of rod 3 extending to form from cap body 1 downwards.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.
In the outer rim that this body of rod 3 comprises the docking chamber 31 that is formed in the body of rod 3, be formed on the body of rod 3 and the outside thread 32 identical with the rotation direction of thread cavity 2 and enclose the inwall 33 that forms docking chamber 31.On inwall 33, there is the internal thread identical with the thread parameter of thread cavity 2 34.Outside thread 32 is covered with the whole body of rod 3.
This docking chamber 31 is extended and is run through this body of rod 3 towards the body of rod 3 from thread cavity 2 and forms.The diameter of the above-mentioned body of rod 3 is less than the diameter of cap body 1.Because the diameter of this body of rod 3 is less than the diameter of cap body 1, so, when the body of rod 3 and bolt (not shown) are fastenedly connected, and the body of rod 3 is screwed in the workpiece (not shown) being connected by the outside thread 32 of its outer installment after, cap body 1 supports on the outer surface of workpiece, plays backstop action.
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: above-mentioned base material is processed to form to nut.The nut that formed in this step 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 interior formation of the body of rod 3 forming in above-mentioned S2 step is docked chamber 31 and form outside thread 32 in the outer rim of the body of rod 3.In this step, this outside thread 32 is identical with the rotation direction of the thread cavity 2 forming in S2 step.In this step, the outside thread 32 forming is covered with the body of rod 3.
S4: the nut that above-mentioned 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 S3 step, in forming docking chamber 31, also comprise the steps: to form the internal thread 34 identical with the thread parameter of the thread cavity 2 in S2 step on enclosing the inwall 33 that forms this docking chamber 31.
Preparation method's technique of above-mentioned nut is simple, easy to operate, by the nut with the body of rod 3 forming, and on this body of rod 3, form outside thread 32 and docking chamber 31, make to prepare between formed nut and workpiece and also form and be threaded by the present invention, thereby when nut is coordinated with bolt, be connected more fastening.
In sum, nut structure is simple, by the body of rod 3 with docking chamber 31 and outside thread 32 is set on nut body 1, and the diameter of this body of rod 3 is less than the diameter of cap body 1, when nut is coordinated with bolt, this body of rod 3 also can be buried underground in the workpiece being fixed, and forms and be threaded between this nut and workpiece, thereby can strengthening stud and nut between be connected, 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.
