Description
Technical field
The present invention is with regard to a kind of Fang Song Tuo ﹝ anti-loosen ﹞ bolt manufacturing methods and its makes bolt unit
Part；Thread Bu ﹝ laterally-extruded thread portion ﹞ shape is extruded using side especially with regard to a kind of
Into Anti-loose bolt manufacture method and its make bolt element.
Background technology
" the Anchor bolt with an of known bolt structure, such as U.S. patent Nos No. US-6454506th number
Outer thread having thread turns with different cross-sectional shape ", which discloses one
Plant fixing bolt or Mao Shuan ﹝ anchor bolt ﹞.The fixing bolt has a Yuan post Luo Gan ﹝ cylindrical
Stem ﹞ and at least a Luo Wen ﹝ thread ﹞ are formed on the cylindrical screw.The screw thread from one it is free Qian Duan ﹝
Free front end ﹞ extend a longitudinal direction Ju Li ﹝ longitudinal extent ﹞.
Hold, the screw thread has several thread Huan ﹝ thread turn ﹞, and along from the free front end with should
The distance between thread ring increases, and the tooth width of at least more than 1/3rd of the cylindrical screw thread ring
﹝ width ﹞ are reduced, and so the one of any two thread rings is met before being followed by Ce Mian ﹝ trailing flank ﹞ and
The Ju Li ﹝ distance ﹞ of the recess width between Ce Mian ﹝ leading flank ﹞ reversely increase.
Although the thread ring of the screw thread is constructively set to not wait tooth width or the recess width such as not, which is only used
To be lifted, its entirety is screwed togather or anchor closes intensity, and which is only applicable on related building part.In fact, in structure
Make the screw thread thread ring do not wait tooth width or etc. recess width cannot not effectively prevent which from sending out after sealed
The problem that life is released or come off.
Another known screw structure, the such as " spiral shell of screw of TaiWan, China patent announcement the TW-475670th
The new patent of tooth structure-improved ", a kind of its screw structural of announcement.The screw includes a screw terminal, a spiral shell
Silk body and several twill threads.The twill thread extends distribution and is arranged on the screw body.In addition,
The wavy thread for being set to an arc by one section of the twill thread on a determining deviation of the screw terminal.
Hold, on the twill thread, the wavy thread extends to be formed and is partial to the neighbouring twill thread.
When sealed, the screw is snapped in a screw using the tight sealed of the wavy thread.Thus, making
The screw obtains preferably firmly sealed, to prevent the screw after sealed to be not susceptible to improper loosening, or very
Come off to accident is not susceptible to.
Although in fact, the wavy thread extends to be formed and being partial to the neighbouring twill thread and can provide closely
The function of screwing togather, but which has the shortcomings that construction is complicated.I.e. the wavy thread is necessary for single thread, side
The single wavy thread can be formed and be partial to the neighbouring rule twill thread.In addition, in the twill spiral shell
The wavy thread is additionally formed on tooth, but which has in fact on thread Gun Zha ﹝ thread-rolling ﹞ processing procedures
The shortcoming of border processing difficulties.
In other words, it is known that bolt structure and its manufacture method certainly exist needs and provide and prevent after sealed
The potential demand that mechanicalness is released.Aforesaid US patent of invention the US-6454506th and TaiWan, China patent
Announce No. TW-475670 be only the reference of the technology of the present invention background and illustrate current technology state of development and
, the scope that it is not intended to limiting the invention.
In view of this, in order to meet above-mentioned technical problem and demand, which provides a kind of Anti-loose bolt to the present invention
