Description
Technical field
The present invention relates to technical field of fastening, more particularly to a kind of check bolt.
Background technology
At present, usually used standard bolt is with being combined into, by spring by nut, screw rod, spring washer, plain washer
Tension force and screw rod, nut between thread friction power reach locking purpose.In use for some time, or in vibration greatly, frequently
Usually there is loose phenomenon in this bolt in the high place of rate.Check bolt on the market often sets opening on bolt now
Pin or series connection wire, but error due to set location often be present, its due intensity is weakened on the contrary.
The utility model patent of Application No. 201420096466.1, a kind of fastening is disclosed apart from adjustable locking spiral shell
There is a nuts bolt, screw rod upper end, and screw rod bottom has forward screw thread section to be connected with reverse thread section the thread segment being integrally formed, positive
The diameter of thread segment is more than the diameter of reverse thread section, and in forward screw thread section, stop nut center has up and down locking nut
The bolt hole of insertion, bolt hole are to be connected together to form by the fastening section and top of bottom the regulation section concentric with fastening section
, there is the internal thread corresponding with reverse thread section on fastening section inwall, stop nut is mounted in reverse thread section through internal thread rotation
On, its upper surface is in contact with the lower surface of locking nut, forms interlocking structure.The disclosed fastening of above-mentioned patent is apart from adjustable
Check bolt, although the locking of locking nut can be realized, the fastening section distance of stop nut is limited, works as locking screw
When during mother's locking very close to bolt head, the fastening section of check bolt can not just play a part of fastening.
The content of the invention
(1) technical problems to be solved
The present invention provides a kind of check bolt, and the bolt is not only simple in structure, is novel in design, and anti-loosing effect is good, makes
With stabilization.
(2) technical scheme
To achieve the above object, the present invention provides following technical scheme：A kind of check bolt, including bolt, the bolt
On be socketed with pad, the outside screw on the bolt in the pad is connected with nut, along institute on the thread segment of the bolt
The length direction for stating bolt is provided with grooving, and the grooving runs through the side of the bolt, and the pad is provided with and the grooving
The reverse taper of cooperation.
Pass through above-mentioned technical proposal, when in use, pad is socketed on the bolt makes pad first to the bolt
On reverse taper be placed in grooving, then nut is connected through a screw thread on bolt, with the rotation of nut, nut
Along bolt axial movement so that moved axially with mobile gasket, the reverse taper on pad gradually moves into grooving, so as to by spiral shell
The thread segment of bolt struts, and effectively prevents the loosening of nut.
In further technical scheme, the reverse taper is strip, and section is isosceles trapezoid, the length of the reverse taper
Diameter of the degree less than the bolt；It is to increase the intensity of reverse taper to set strip, and the length of strip reverse taper is less than
The diameter of bolt is that nut is screwed on bolt for convenience, uses section strutting the screw thread of bolt for the reverse taper of isosceles trapezoid
Uniform force during section.
In further technical scheme, the conical surface of the reverse taper is provided with hangnail；Hangnail is set further to prevent
Reverse taper skids off from grooving on pad.
In further technical scheme, the grooving passes through the axis of the bolt；Grooving passes through the bolt axis energy
The intensity of bolt thread section is enough effectively ensured.
In further technical scheme, the nut is hex nut；It is convenient and practical using hex nut.
In further technical scheme, the pad is made up of stainless steel material；First can using stainless steel material
Corrosion effectively is prevented, secondly intensity height can effectively avoid deforming in the grooving of bolt thread section.
(3) beneficial effect
Compared with prior art, technical scheme has advantages below：The check bolt is simple in construction, uses
When pad be socketed on the bolt reverse taper on pad is placed in grooving, then nut is connected through a screw thread
On bolt, with the rotation of nut, axial movement of the nut along bolt and then moved axially with mobile gasket, on pad
Reverse taper gradually moves into grooving, so as to which the thread segment of bolt be strutted, effectively prevents the loosening of nut.

Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation describes, it is clear that described embodiment is only part of the embodiment of the present invention, rather than whole embodiments.It is based on
Embodiment in the present invention, those of ordinary skill in the art are obtained every other under the premise of creative work is not made
Embodiment, belong to the scope of protection of the invention.
Fig. 1-3 are referred to, the present invention provides a kind of technical scheme：A kind of check bolt, including bolt 1, on the bolt 1
It is socketed with pad 2, the outside screw on the bolt 1 in the pad 2 is connected with nut 3, edge on the thread segment of the bolt 1
The length direction of the bolt 1 is provided with grooving 101, and the grooving 101 runs through the side of the bolt 1, and the pad 2 is provided with
The reverse taper 201 coordinated with the grooving.
When in use, pad 2 is socketed on the bolt 1 puts the reverse taper 201 on pad 2 first to the bolt
Put in grooving 101, then nut 3 is connected through a screw thread on bolt 1, with the rotation of nut 3, nut 3 is along spiral shell
The axial movement of bolt 1 and then being moved axially with mobile gasket 2, the reverse taper 201 on pad 2 gradually moves into grooving 101, so as to
The thread segment of bolt 1 is strutted, effectively prevents the loosening of nut.
The reverse taper 201 is strip, and section is isosceles trapezoid, and the length of the reverse taper 201 is less than the spiral shell
The diameter of bolt 1, here reverse taper 201 using strip be in order to increase the intensity of reverse taper 201, strip reverse taper 201
It is that nut 3 is screwed on bolt 1 for convenience that length, which is less than the diameter of bolt 1, uses section to exist for the reverse taper 201 of isosceles trapezoid
Uniform force when strutting the thread segment of bolt 1.
The conical surface of the reverse taper 201 is provided with hangnail 202, sets hangnail 202 further to prevent back taper on pad 2
Body 201 skids off from grooving 101；The grooving 101 passes through the axis of the bolt 1, and grooving 101 passes through the axis of bolt 1
It can effectively ensure that the intensity of the thread segment of bolt 1.
The nut 3 is hex nut, and the pad 2 is made up of stainless steel material, first can using stainless steel material
Enough effectively to prevent corrosion, secondly intensity height can effectively avoid deforming in the grooving of bolt thread section.
Described above is only the preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, without departing from the technical principles of the invention, some improvements and modifications can also be made, these improvements and modifications
Also it should be regarded as protection scope of the present invention.
