Abstract
A kind of round end hexagonal neck bolt, including head and the body of rod, head top surface is provided with hexagonal counterbore, body of rod lower end is provided with external screw thread, head bottom surface is provided with hexangle type neck, for hexangle type neck between head and the body of rod, the circumscribed circular diameter of hexangle type neck is more than the circumscribed circular diameter of hexagonal counterbore and less than the diameter on head.The utility model provides a kind of round end hexagonal neck bolt, by setting hexagonal structure in neck, facilitates dismounting.
Description
Technical field
The utility model belongs to technical field of fastening, refers in particular to a kind of round end hexagonal neck bolt.
Background technology
The generally interior hexagonal counterbore aperture of existing soket head cap screw is smaller, and when such as running into high torque, tightening tool is easy
Skidded with counterbore, it has not been convenient to dismount.
Utility model content
The purpose of this utility model is to provide a kind of round end hexagonal neck bolt, by setting hexagonal structure, side in neck
Dismounting.
What the purpose of this utility model was realized in：A kind of round end hexagonal neck bolt, including head and the body of rod, head top
Face is provided with hexagonal counterbore, and body of rod lower end is provided with external screw thread, and head bottom surface is provided with hexangle type neck, hexangle type neck between head and
Between the body of rod, the circumscribed circular diameter of hexangle type neck is more than the circumscribed circular diameter of hexagonal counterbore and less than the diameter on head.
By using above-mentioned technical proposal, in initial installation, fastening tool can be used to coordinate with hexagonal counterbore, quick rotation
Enter, when moment of torsion increases to certain value generation and screws in difficult, diverter tool is further using the instrument coordinated with hexangle type neck
Tighten；When dismounting similarly, first preferably coordinate with hexangle type neck, bolt is unscrewed, then pass through the fast quick-detach of hexagonal counterbore.
Preferably, the hexangle type neck is provided with the jack of radial direction.
Preferably, the jack is through hole.
By using above-mentioned technical proposal, when temporarily can not find with hexangle type neck tool, jack is inserted by rod member
Mode control bolt to rotate, play substitution effect.Jack can run through or be blind hole structure, as needed selection.
Preferably, it is provided with escape between the hexangle type neck and the body of rod.
By using above-mentioned technical proposal, the setting of escape makes the bottom surface of hexangle type neck more smooth, coordinates pad
During piece, pad can with hexangle type neck is more smooth is bonded.
Preferably, the thickness of the hexangle type neck is more than the thickness on head.
By using above-mentioned technical proposal, the cooperation of spanner and hexangle type neck is facilitated, while spanner side can be supported
Hexangle type neck bottom surface is leaned against, limitation slides axially, and ensure that the reliability of dismounting.

Fig. 1 is front view of the present utility model；
Fig. 2 is upward view of the present utility model.
Reference：1st, head；2nd, hexagonal counterbore；3rd, hexangle type neck；4th, jack；5th, the body of rod；6th, external screw thread；7th, withdrawing
Groove.
Embodiment
The utility model is further described with specific embodiment below in conjunction with the accompanying drawings, referring to Fig. 1-2：
A kind of round end hexagonal neck bolt, including head 1 and the body of rod 5, the top surface of head 1 are provided with hexagonal counterbore 2, the lower end of the body of rod 5
Provided with external screw thread 6, the bottom surface of head 1 is provided with hexangle type neck 3, and hexangle type neck 3 is between head 1 and the body of rod 5, hexangle type neck
The circumscribed circular diameter in portion 3 is more than the circumscribed circular diameter of hexagonal counterbore 2 and less than the diameter on head 1.It is arranged such, fastening can be used
Instrument coordinates with hexagonal counterbore 2, quick precession, when moment of torsion increase to certain value occur screw in it is difficult when, diverter tool, using with
The instrument that hexangle type neck 3 coordinates further is tightened；When dismounting similarly, first preferably coordinate with hexangle type neck 3, by bolt
Unscrew, then pass through 2 fast quick-detach of hexagonal counterbore.
Wherein, the hexangle type neck 3 is provided with the jack 4 of radial direction, and the jack 4 is through hole.With hexangle type neck 3
When instrument temporarily can not find, control bolt to rotate by way of rod member inserts jack 4, play substitution effect.Jack 4 can run through
Or be blind hole structure, selection as needed.
Wherein, escape 7 is provided between the hexangle type neck 3 and the body of rod 5.The setting of escape 7 allows hexangle type neck 3
Bottom surface it is more smooth, during tie spacer, pad can with hexangle type neck 3 is more smooth is bonded.
Wherein, the thickness of the hexangle type neck 3 is more than the thickness on head 1.It is arranged such, facilitates spanner and hexangle type
The cooperation of neck 3, while spanner side can be resisted against the bottom surface of hexangle type neck 3, limitation slides axially, and ensure that dismounting can
By property.
Above-described embodiment is only preferred embodiment of the present utility model, not limits protection model of the present utility model according to this
Enclose, therefore：All equivalence changes done according to structure of the present utility model, shape, principle, all should be covered by protection of the present utility model
Within the scope of.
