Abstract
The utility model is related to a kind of check bolt, including head and thread rod part, has step between the head and thread rod part, and being provided with to the step periphery from inside the thread rod part can be with the perforation of ft connection；Multigroup being communicated with perforation and to the inclined hole extended on the thread rod part periphery is additionally provided with the thread rod part internal-internal；The inclined hole, perforation and the head and thread rod part integrated injection molding.A kind of check bolt of the present utility model, can not only effectively prevent from loosening during transport or long-term use, and increased fastening performance, increased the security reliability of transport, simple and reasonable for structure such that it is able to avoid triggering security incident.
Description
Technical field
The utility model is related to a kind of bolt, and in particular to a kind of check bolt, belongs to technical field of fastening.
Background technology
The use of bolt extensively, needs to be fitted close between bolts and nuts in many instances, to prevent bolt looseness.
Such as the bolt on automobile, the bolt looseness method that solves conventional at present is one spring washer of addition between bolts and nuts, with
Prevent bolt looseness.Even if but be so also the possibility for reducing bolt looseness, not for the real original of bolt pine
Because solving.
Utility model content
The purpose of this utility model is to overcome the shortcomings of that prior art is present, there is provided a kind of check bolt, can not only be had
Effect prevents from loosening, and increased fastening performance, the security reliability of transport is increased, such that it is able to avoid triggering safe thing
Therefore.
To reach above-mentioned purpose, the technical solution adopted in the utility model is：A kind of check bolt, including head and screw thread
Bar portion, has step between the head and thread rod part, from inside the thread rod part to setting on the step periphery
Having can be with the perforation of ft connection；Multigroup being communicated with perforation and to the spiral shell is additionally provided with the thread rod part internal-internal
The inclined hole extended on rasp bar portion periphery；The inclined hole, perforation and the head and thread rod part integrated injection molding.
Preferably, the inclined hole is connected in ratchet-like with the perforation, and the perforation is L-shaped, while in the screw thread
In bar portion, another side is in the step, and is extended to step periphery.
Preferably, it is embedded with card article on the thread rod part bottom cylindrical face.
Preferably, the card article has multigroup and circular array.
Due to the utilization of above-mentioned technical proposal, the utility model has following advantages compared with prior art：
A kind of check bolt of the present utility model, can not only effectively prevent from loosening during transport or long-term use, and
And fastening performance is increased, the security reliability of transport is increased, such that it is able to avoid triggering security incident, simple structure, conjunction
Reason.
Brief description of the drawings
Technical solutions of the utility model are described further below in conjunction with the accompanying drawings：
Accompanying drawing 1 is a kind of structural representation of check bolt of the present utility model；
Wherein：1- heads；2- thread rod parts；3- steps；4- perforates；5- inclined holes；6- card articles.
Specific embodiment
Below in conjunction with the accompanying drawings and specific embodiment the utility model is described in further detail.
As shown in Figure 1, a kind of check bolt described in the utility model, including head 1 and thread rod part 2, described
There is step 3, step 3 can be the movable step with internal thread, from inside thread rod part 2 between head 1 and thread rod part 2
Being provided with to the periphery of the step 3 can be with the perforation 4 of ft connection；It is additionally provided with inside the thread rod part 2 multigroup
Communicated with perforation 4 and to the inclined hole 5 extended on the periphery of the thread rod part 2；The inclined hole 5, perforation 4 with the head 1 and
The integrated injection molding of thread rod part 2.Wherein inclined hole 5 is connected in ratchet-like with perforation 4, and inclined hole direction is downward-sloping, with axial direction
Angle between perforation is 45 °, and perforation 4 is L-shaped, while in the thread rod part 2, another side is in the step 3,
And extend to the periphery of step 3.Bolt of the present utility model is worn when vibration is produced during long-term use or in transportation
The setting of hole 4 and inclined hole 5 is easy to discharge the gas of being produced because of vibration in screw thread interporal lacuna, so as to be conducive to screwed hole with
The acquisition of vacuum between thread pitch, so as to increase its fastening performance.
Four groups or six groups and circular array card article 6 are embedded with the bottom cylindrical face of thread rod part 2, work as the utility model
Bolt when screwing in nut, the screw thread in nut makes card article produce dilatancy, to being contacted with thread rod part 2, play and push up again and again
Press urgent effect, and make there is no tolerance between nut and bolt, increase its coefficient of friction, improve its fastening performance, prevent
The loosening vibrated and cause, security reliability are produced during transport or use.
The above is only concrete application example of the present utility model, any limit is not constituted to protection domain of the present utility model
System.All use equivalents or equivalence replacement and the technical scheme that is formed, all fall within the utility model rights protection scope it
It is interior.
