Abstract
The present invention provides a kind of fastening bolt, nut including shank of bolt He the one end for being arranged at the shank of bolt, external screw thread is provided with the shank of bolt, the one end of the shank of bolt away from the nut offers the groove along shank of bolt axial direction, internal thread is provided with the inwall of the groove, it is described externally threaded to screw that screwing for direction and the internal thread is in opposite direction, and the depth of the groove is less than 1/5th of the external thread length.The fastening bolt of the embodiment of the present invention, by setting internal thread and external screw thread, and externally threaded to screw screwing for direction and internal thread in opposite direction, during use, collocation nut and another screw rod use, wherein, nut is arranged on external screw thread, another screw rod screws in the internal thread of fastening bolt, after nut screws on external screw thread, if rotated to the direction loosened, another bolt can be driven to be rotated to fastening direction, so as to avoid nut from coming off, fixed effect ensure that.
Description
Technical field
The present invention relates to mechanical field, more particularly to a kind of fastening bolt.
Background technology
Existing bolt collocation nut fixes various structures in use, due to reasons such as vibrations, easily loosens, causes
Bolts and nuts are separated, so as to influence fixed effect.
The content of the invention
Based on this, it is necessary to the problem of easily being loosened for existing bolt, propose a kind of fastening bolt of good fixing effect.
A kind of fastening bolt, including shank of bolt and be arranged at the shank of bolt one end nut, set on the shank of bolt
External screw thread is equipped with, the one end of the shank of bolt away from the nut offers the groove along shank of bolt axial direction, the groove
Inwall on be provided with internal thread, it is described externally threaded to screw direction and screwing for the internal thread is in opposite direction, the groove
Depth be less than the external thread length 1/5th.
The fastening bolt of the embodiment of the present invention, by setting internal thread and external screw thread, and it is externally threaded screw direction with it is interior
Screwing for screw thread is in opposite direction, in use, collocation nut and another screw rod use, wherein, nut is arranged on external screw thread, another
Screw rod screws in the internal thread of fastening bolt,, can band if rotated to the direction loosened after nut screws on external screw thread
Move another bolt to rotate to fastening direction, so as to avoid nut from coming off, ensure that fixed effect.
Brief description of the drawings
Fig. 1 is the structural representation of the fastening bolt in the embodiment of the present invention；
Fig. 2 is Fig. 1 another multi-angled view.
Embodiment
For the ease of understanding the present invention, the present invention is described more fully below with reference to relevant drawings.In accompanying drawing
Give the preferred embodiment of the present invention.But the present invention can realize in many different forms, however it is not limited to herein
Described embodiment.On the contrary, the purpose for providing these embodiments is to make the understanding to the disclosure more saturating
It is thorough comprehensive.
Unless otherwise defined, all of technologies and scientific terms used here by the article is with belonging to technical field of the invention
The implication that technical staff is generally understood that is identical.Term used in the description of the invention herein is intended merely to description tool
The purpose of the embodiment of body, it is not intended that in the limitation present invention.Term as used herein " and/or " include one or more phases
The arbitrary and all combination of the Listed Items of pass.
The present invention provides a kind of fastening bolt.
As depicted in figs. 1 and 2, in one embodiment, the fastening bolt includes shank of bolt（Do not identify）It is described with being arranged at
The nut 10 of one end of shank of bolt, is provided with external screw thread 20 on the shank of bolt, the shank of bolt away from the nut 10 one
End offers the groove 40 along shank of bolt axial direction, and internal thread 30, the external screw thread are provided with the inwall of the groove 40
20 to screw screwing for direction and the internal thread 30 in opposite direction.
In use, the fastening bolt needs arrange in pairs or groups nut and the use of another screw rod, wherein, nut is arranged at external screw thread 20
On, the size of another screw rod matches with the groove 40, and another screw rod is screwed in groove 40, to realize and fastening bolt
It is fixedly connected.
The depth of groove 40 described in the present embodiment is less than 1/5th of the length of external screw thread 20, to ensure shank of bolt
Intensity.
External screw thread 20 in the present embodiment screw direction and the internal thread 30 screw it is in opposite direction refer to if
The direction that screws of external screw thread 20 is clockwise, then the direction that screws of internal thread 30 is counterclockwise, or the side of screwing of external screw thread 20
To being counterclockwise, then the direction that screws of internal thread 30 is clockwise.Like this, nut drives another to when loosening direction and rotating
One bolt rotates, and because both screw is in opposite direction, now, if another bolt rotates with nut simultaneously, then another
One bolt is rotated to the direction screwed, now, because another bolt is tightened, nut can be avoided to come off.
The fastening bolt of the embodiment of the present invention, by setting internal thread 30 and external screw thread 20, and the side of screwing of external screw thread 20
To in opposite direction with screwing for internal thread 30, in use, after nut, can band if rotated to the direction loosened
Move another bolt to rotate to fastening direction, so as to avoid nut from coming off, ensure that fixed effect.
Embodiment described above only expresses the several embodiments of the present invention, and its description is more specific and detailed, but simultaneously
Can not therefore it be construed as limiting the scope of the patent.
It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise,
Various modifications and improvements can be made, these belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention
It should be determined by the appended claims.
