Abstract
The utility model discloses a kind of superhigh intensity bolt, including integrally formed bolt head and screw rod, the junction of the bolt head and screw rod is equipped with discoid installation abutting portion, the bolt head is polygon star-shaped cylinder structure, it is internally provided with blind hole, the side of the bolt head is equipped with four pin holes for being uniformly distributed and connecting with blind hole, and the screw rod includes sequentially connected light bar segment, changeover portion and thread segment, and light bar segment is connected with installation abutting portion.The utility model uses the bolt head of polygon star-shaped cylinder structure, the contact area of spanner and bolt can be effectively increased, so as to enhance the screwing force for the spanner that bolt head can be born so that bolt head is more durable, avoids having skidded in rundown process；Pin hole is equipped with bolt head at the same time, by interting axis pin in pin hole, the mating connection ability between bolt head and spanner can be recovered when bolt head can not be dismantled because of corrosion.
Description
Technical field
It the utility model is related to threaded connector technical field, more particularly to a kind of superhigh intensity bolt.
Background technology
Bolt is by head and screw rod a kind of fastener dimerous, need to be coordinated with nut, for being fastenedly connected two
A part with through hole, this type of attachment claim to be bolted.Generally use in daily life hexagon-headed bolt or
Hexagon socket head cap screw, and tightened and dismantle by spanner, spanner easily occurs in rundown process because apex angle is worn
Slide, or can not be unloaded because of corrosion using spanner.
Utility model content
The purpose of this utility model is and a kind of superhigh intensity spiral shell proposed in order to solve shortcoming existing in the prior art
Bolt.
To achieve these goals, the utility model employs following technical solution：
A kind of superhigh intensity bolt, including integrally formed bolt head and screw rod, the junction of the bolt head and screw rod
Equipped with discoid installation abutting portion, the bolt head is polygon star-shaped cylinder structure, is internally provided with blind hole, the bolt head
Side be equipped with four pin holes for being uniformly distributed and connecting with blind hole, the screw rod includes sequentially connected light bar segment, transition
Section and thread segment, light bar segment are connected with installation abutting portion.
Preferably, the installation abutting portion and the angle that bolt head connection is circular cone structure, its busbar and axis
For degree to degree.
Preferably, the blind hole is circular cone structure, its large scale end is located on the end face of bolt head, and busbar and axis
Angle degree of being to spend.
Preferably, the end face of the bolt head is marked equipped with bolt.
Preferably, twice of the length of the changeover portion no more than thread pitch on thread segment.
In the utility model, using the bolt head of polygon star-shaped cylinder structure, contact of the spanner with bolt can be effectively increased
Area, so as to enhance the screwing force for the spanner that bolt head can be born so that bolt head is more durable, avoids going out in rundown process
Now skid；Pin hole is equipped with bolt head at the same time, the widow bolts in pin hole can be passed through when bolt head can not be dismantled because of corrosion
Axis, recovers the mating connection ability between bolt head and spanner.
Brief description of the drawings
Fig. 1 is the main structure diagram of the utility model；
Fig. 2 is the side structure schematic view of the utility model；
Fig. 3 is the bolt head schematic cross-sectional view of the utility model；
Fig. 4 is the screw rod partial enlargement structural representation of the utility model.
In figure：1 bolt head, 11 blind holes, 12 pin holes, 2 screw rods, 21 light bar segments, 22 changeover portions, 23 thread segments, 3 installations contradict
Portion.
Embodiment
The following is a combination of the drawings in the embodiments of the present utility model, and the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.
Reference Fig. 1-4, a kind of superhigh intensity bolt, including integrally formed bolt head 1 and screw rod 2, bolt head 1 and screw rod
2 junction is equipped with discoid installation abutting portion 3, and installation abutting portion 3 and 1 connection of bolt head are circular cone structure, its
The angle of busbar and axis is 30 degree to 60 degree.
Bolt head 1 is polygon star-shaped cylinder structure, and the end face of bolt head 1 is marked equipped with bolt, and bolt head 1 is internally provided with
Blind hole 11, blind hole 11 are circular cone structure, its large scale end is located on the end face of bolt head 1, and the angle of busbar and axis is 0
Degree is to 10 degree.
The side of bolt head 1 is equipped with four pin holes 12 for being uniformly distributed and connecting with blind hole 11, and screw rod 2 includes connecting successively
Light bar segment 21, changeover portion 22 and the thread segment 23 connect, light bar segment 21 are connected with installation abutting portion 3, and the length of changeover portion 22 is not
More than twice of thread pitch on thread segment 23.
Operation principle：When the utility model is used, using the special spanner to match with bolt head 1, bolt is screwed into
Treat in the threaded hole of connector, the inner wall of spanner contacts at the same time with multiple sides of bolt head 1, increase spanner and bolt head 1
Contact area, enhances the screwing force that bolt head 1 can bear, and when the dismounting of bolt needs and bolt surface and corrosion is than more serious
When, axis pin can be inserted into the pin hole 12 on bolt head 1, pass through the mating connection of axis pin and spanner so that spanner can be as dismounting
Normal bolt equally dismantles the serious bolt of surface corrosion.
The above, is only the preferable embodiment of the utility model, but the scope of protection of the utility model is not
This is confined to, any one skilled in the art is in the technical scope that the utility model discloses, according to this practicality
New technical solution and its utility model design are subject to equivalent substitution or change, should all cover the protection model in the utility model
Within enclosing.
