Abstract
The utility model relates to a fastening and linking part, in particular to a hexagon-headed bolt which comprises an inverted hexagonal isosceles trapezoidal bolt head and a bolt bar integrated with the bolt head, wherein the top of the inverted hexagonal isosceles trapezoidal bolt head is provided with an inner hexagonal hole for the insertion of a tool to rotate the bolt, an inner round hole with threads in a direction reverse to that of the threads on the bolt bar, and a cross slot arranged at the bottom of the inner round hole. The hexagon-headed bolt is very applicable to special positions and occasions, does not damage the surface smoothness of a fixed object, and can be well combined with the fixed object in a coordinative way, thus having good effect.
Description
Technical field
The utility model relates to a kind of fastening coupling, specifically a kind of hexagon head bolt.
Background technique
The bolt head of existing plain bolt generally all is shapes such as hexagon, square, octagon, and these bolts are used very extensive, use also very convenient.But if use in some special position and occasion, effect is unsatisfactory.For example the isosceles trapezoid of falling hexagonal body or Embedded position wide at the top and narrow at the bottom or occasion and plate are twisted unfavorable position, position or occasion, after using common hexagon, square bolt, bolt head seems extremely inharmonious with the Embedded junction that connects, space when plate is twisted is not enough, the disadvantage that is connected that exists the planarization on the easy damaging fixed thing of bolt head surface and influence fixture and other objects causes the difficulty of dismantlement work in addition.
The model utility content:
The technical problems to be solved in the utility model provides a kind of bolt that can combine with the coordination of fixture surface and can be for convenience detach.
Technical solution of the present utility model is: a kind of bolt of structure that has is provided.This bolt is provided with threaded bolt shank and bolt head, and the top of described bolt head is provided with an inner hexagonal hole that can be rotated bolt for instrument inserts and has cross recess with the interior circular hole and the interior circular hole bottom that have with bolt shank screw thread reverse thread.
Adopt the bolt of above structure, compared with prior art, the utlity model has following advantage:
Because bolt head is arranged to said structure, the bolt of this shape and structure, be well suited for the fixture of being inverted hexagonal isosceles trapezoid body or shape embedded surface wide at the top and narrow at the bottom that has of privileged sites or occasion, this bolt can damaging fixed thing surface planarization, bolt head can not highlight, can combine very in phase with fixture, can adopt multiple instrument dismounting, have good using effect.
Further, described bolt head is set to inverted hexagonal isosceles trapezoid body, described inner hexagonal hole, interior circular hole and cross recess be arranged on bolt axially on hexagonal isosceles trapezoid body in.
Further, described inner hexagonal hole is positioned at the top of bolt head, and its axial depth is half of bolt head axial depth.
Further, described interior circular hole is positioned at the bottom of bolt head, and its axial depth is half of bolt head axial depth.
Further, the bottom of described interior circular hole is provided with cross recess, and cross recess is positioned at the connecting part of bolt head and bolt shank, says that exactly cross recess is positioned on the upper-end surface of bolt shank, and the length of cross recessed groove is less than the diameter of bolt shank.
Description of drawings:
Fig. 1 is a worm's eye view; Fig. 2 is a plan view; Fig. 3 is a plan view; Fig. 4 is the partial sectional view of bolt.
Shown in the figure: the 1st, bolt head, the 2nd, bolt shank; The 3rd, inner hexagonal hole; The 4th, interior circular hole; The 5th, cross recess; The 6th, hexagonal isosceles trapezoid body; The 7th, the screw thread of bolt shank; The 8th, the screw thread of interior circular hole.
Embodiment:
Below in conjunction with the drawings and specific embodiments the utility model is described further.
As shown in the figure, the utility model comprises hexagonal isosceles trapezoid body (6) and is the bolt shank of one (2) with hexagonal isosceles trapezoid body (6); The top of described hexagonal isosceles trapezoid body (6) be provided with an inner hexagonal hole (3) that can be rotated bolt for instrument inserts and have and the interior circular hole (4) of screw thread (7) reverse thread (8) of bolt shank (2) and interior circular hole (4) bottom have cross recess (5); Described inner hexagonal hole (3) is positioned at the top of bolt head (1), and its axial depth is half of bolt head (1) axial depth; Circular hole (4) is positioned at the bottom of bolt head (1) in described, and its axial depth is half of bolt head (1) axial depth; Described cross recess (5) is positioned at the bottom of described circular hole (4), and the connecting part of bolt head (1) and bolt shank (2) says that exactly cross recess (5) is positioned on the upper-end surface of bolt shank (2), and the length of the groove of cross recess (5) is less than bolt shank (2 diameter.
