Abstract
The utility model discloses a kind of flange bolt, including hexagon-head and screw rod, screw rod is provided with a word groove back to hexagon-head one side.By a word male cooperation of a word groove and via bottoms, screw rod is positioned.When i.e. tighting a bolt, being screwed to a certain degree, having projection bottom screw, projection can embed a word groove, thus bolt is all screwed to same torsional moment each time, will revert to the position that is screwed to needed for original start by bolt.
Description
Technical field
The utility model relates to bolt, is specifically related to a kind of flange bolt.
Background technology
Bolt is to utilize the inclined-plane circular rotating of object and the physics of frictional force and mathematical principle, fastens by easy stages
The instrument of implements parts.Bolt is the general saying of securing member, daily pet phrase.Bolt is work indispensable in daily life
Industry necessity: the minimum bolt using such as camera, glasses, clock and watch, electronics etc.；TV, electric product, musical instrument, furniture etc.
General bolt；Then use large-sized bolt, nut as engineering, building, bridge；Traffic tool, aircraft, electric car, automobile etc. are then
It is used in combination for big stove bolt.Vital task industrially born by bolt, as long as there is industry on the earth, then the function of bolt is eternal
Important.Bolt is the joint invention in people's productive life over the past thousands of years, and from the point of view of application, it is the first big of the mankind
Invention.
Generally use flange bolt on automobile cylinder lid and fix cylinder block.Existing flange bolt is as it is shown in figure 1, one
Flange bolt includes hexagon-head the 1st, ring flange 5 and screw rod 2, and described screw rod 2 is provided with screw thread, described hexagon-head the 1st, ring flange 5
One-body molded with screw rod 2.
Cylinder needs periodically to carry out maintenance maintenance, now needs to back out flange bolt, dismantles cylinder cover.Maintenance weighs after completing again
Newly tighten flange bolt.Sealing in order to ensure cylinder cap uniformly will make cylinder cap deform again because of overexertion, need to be by flange
Bolt be screwed to and dismantle before same torsional moment, home position will be reverted to by flange bolt.At the torque spanner without specialty
In the case of, it is difficult to flange bolt is reverted to home position.
Utility model content
The deficiency existing for prior art, the purpose of this utility model is to provide a kind of flange bolt, screw rod back to
Turret head one side is provided with a word groove, by a word male cooperation of a word groove and via bottoms, positions screw rod, will
Bolt is all screwed to same torsional moment each time, will revert to home position by bolt.
For achieving the above object, the utility model provides following technical scheme:
A kind of flange bolt, including hexagon-head and screw rod, is characterized in that: it is recessed that screw rod is provided with a word back to turret head one side
Groove.
By using technique scheme, by a word male cooperation of a word groove and via bottoms, screw rod is carried out
Positioning.When i.e. tighting a bolt, being screwed to a certain degree, having projection bottom screw, projection can embed a word groove, thus bolt is every
It is once all screwed to same torsional moment, the position that is screwed to needed for original start will be reverted to by bolt.
It of the present utility model is further arranged to: described word groove four limit is provided with chamfering.
By using technique scheme, projection is facilitated to slip into groove.During due to stubborn bolt, screw rod is to rotate, then convex
Rise confronting grooves rotate, when stubborn screw rod to a certain extent, projection rotates into groove.Groove four limit is provided with chamfering, reduces convex
The active force to its horizontal direction for groove when playing precession and screw out groove, i.e. reduces resistance.Facilitate the installation of flange bolt
And dismounting.
It of the present utility model is further arranged to: described screw rod includes polished rod portion and threaded portion, and described polished rod portion is positioned at spiral shell
Bar nearly hexagon-head one end, described polished rod portion diameter is less than threaded portion diameter.
By using technique scheme, polished rod portion is different with the diameter of threaded portion, and the loading force that can bear is also different,
When flange bolt bears variable force, the possibility of fracture reduces, and is conducive to being connect by variable force.
It of the present utility model is further arranged to: described polished rod portion includes straight-bar portion and sealing, and described sealing is positioned at
Screw rod nearly hexagon-head one end, described sealing diameter is more than straight-bar portion.
By using technique scheme, certainly exist various defect and shape due to the surface of engineering goods and size is inclined
Difference, therefore, inevitably results from gap in junction.Gap between the composition surface in bolt and hole is sealed by sealing, protects
Demonstrate,prove bolt union piece stable.
It of the present utility model is further arranged to: described sealing is chamfered transition to straight-bar portion.
By using technique scheme, when tightening flange bolt, the resistance that sealing is subject to is little, facilitates sealing to enter
In hole, facilitate the installation of flange bolt.And the cross-sectional area of sealing is different, can be connected with the empty interference of different-diameter, make
Fastening parts more stable.
It of the present utility model is further arranged to: described screw rod is provided with ring flange, and described ring flange is positioned at screw rod and hexagonal
In the middle of head.
By using technique scheme, ring flange can be worked as plain cushion and be used, if more pacifying when connecting softer, not wear-resisting part
Entirely, perforation is not resulted in.It is not required to add plain cushion when installing simultaneously, easy for installation.
It of the present utility model is further arranged to: described ring flange is provided with buffer disc relative to screw rod one side.
By use technique scheme, buffer disc can somewhat deformation, can by part connect more fastening.And flange bolt
When vibrated can damping, prevent vibration when threaded loosen.
The utility model has the advantage that the position that bolt reverts to be screwed to needed for original start, and union piece is even
Connect fastening, easy installation and removal, be conducive to being connect by variable force, do not result in perforation.

Detailed description of the invention
Referring to the drawings the utility model is described further.
As in figure 2 it is shown, a kind of flange bolt, including hexagon-head 1 and screw rod 2.Flange bolt positioning for convenience, screw rod
2 are provided with a word groove 3 back to hexagon-head 1 one side.The installation and removal of flange bolt for convenience, word groove 3 four limit sets
There is chamfering 4.Being provided with ring flange 5 between screw rod 2 and hexagon-head 1, ring flange 5 can be worked as plain cushion and be used, if connecting softer, not wear-resisting
Part when safer, do not result in perforation.Be provided with buffer disc 6 between ring flange 5 and screw rod 2, buffer disc 6 can deformation, can be by
The more fastening that part connects.
As shown in Figures 2 and 3, screw rod 2 includes sealing the 212nd, straight-bar portion 211 and threaded portion 22.Sealing 212 relative six
Angle head 1.Straight-bar portion 211 is positioned between sealing 212 and threaded portion 22.Threaded portion 22 is provided with screw thread, makes connection more fasten.Directly
Bar portion 211 is polished rod, and diameter is less than threaded portion 22, the beneficially connection of variable force.Sealing 212 diameter is more than straight-bar portion 211,
Connection is made more to fasten.Sealing 212 is chamfered transition to straight-bar portion 211, facilitates the installation of flange bolt.
As shown in Figure 4 and Figure 5, during this flange bolt fastening article, the word by a word groove 3 and via bottoms is protruding
Coordinate, screw rod 2 is positioned, bolt is all screwed to each time same torsional moment, original disposition will be screwed to by bolt, protect
Sealing between exhibit product uniformly will not make again article deforming because of overexertion.
The above is only preferred embodiment of the present utility model, and protection domain of the present utility model is not limited merely to
