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 the first screw rod and the second screw rod, first screw rod include shank of bolt and are arranged at institute
The nut of one end of shank of bolt is stated, external screw thread is provided with the shank of bolt, the one end of the shank of bolt away from the nut is opened
Provided with the groove along shank of bolt axial direction, be provided with internal thread on the inwall of the groove, the size of second screw rod with
The groove match, second screw surface are provided with the fixed thread to match with the internal thread, and described second
Screw rod is meshed by the internal thread with the fixed thread to be fixed in the groove, on the external screw thread of first screw rod
It is arranged with clamp nut, the clamp nut is provided with the fixture block corresponding with second bolt, described externally threaded to screw
Direction and screwing for the internal thread are in opposite direction.
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, after nut, if rotated to the direction loosened, can drive the second spiral shell
Bolt rotates 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.
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 shown in figure 1, in one embodiment, the fastening bolt includes the first screw rod 10 and the second screw rod 20, described first
Screw rod 10 includes shank of bolt（Do not identify）With the nut 11 of one end for being arranged at the shank of bolt, it is provided with the shank of bolt outer
Screw thread 12, the one end of the shank of bolt away from the nut 11 offer the groove along shank of bolt axial direction（It is invisible）, institute
State and internal thread is provided with the inwall of groove, size and the groove match of second screw rod 20, second screw rod
20 surfaces are provided with the fixed thread to match with the internal thread（Do not identify）, and second screw rod 20 passes through the interior spiral shell
Line is meshed with the fixed thread to be fixed in the groove, and fastening spiral shell is arranged with the external screw thread 12 of first screw rod 10
Mother 30, the external screw thread 12 to screw screwing for direction and the internal thread in opposite direction.
The direction that screws of external screw thread 12 in the present embodiment refers to if outer in the opposite direction with screwing for the internal thread
The direction that screws of screw thread 12 is clockwise, then the direction that screws of internal thread is counterclockwise, or the direction that screws of external screw thread 12 is
Counterclockwise, then the direction that screws of internal thread is clockwise.Like this, nut 30 to loosen direction rotate when, drive the second spiral shell
Bolt rotates, and because both screw is in opposite direction, now, if the second bolt rotates with nut 30 simultaneously, then second
Bolt is rotated to the direction screwed, now, because the second bolt is tightened, nut 30 can be avoided to come off, the present embodiment
In the fixture block 31 of triangle is provided with nut 30, corresponding Access Division is provided with the second bolt so that
The bolt of nut 30 and second is abutted against, to prevent nut 30 from coming off, it is clear that nut 30 and can also be realized by other structures
The abutting of two bolts.
The fastening bolt of the embodiment of the present invention, by setting internal thread and external screw thread 12, and external screw thread 12 screws direction
It is in opposite direction with screwing for internal thread, in use, after nut 30 screws, if rotated to the direction loosened, can drive
Second bolt rotates to fastening direction, so as to avoid nut 30 from coming off, ensure that fixed effect.Embodiment described above is only expressed
The several embodiments of the present invention, it describes more specific and in detail, but therefore can not be interpreted as to patent of invention model
The limitation enclosed.
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.
