Abstract

The invention discloses a kind of special-shaped screw, comprising: first body of rod, second body of rod, coiled hair, gathering sill, annular groove and oil-through hole;Described first body of rod is arranged on coiled hair upper surface;Described second body of rod is arranged on coiled hair lower surface;Described first body of rod is provided with annular groove;Described second body of rod lower end is provided with screw thread;A gathering sill is offered in any side of described second body of rod;An oil-through hole is offered at described special-shaped screw center.Present configuration is simple, reasonable in design, and installation and removal are convenient easily, have enough intensity and good manufacturability, and low cost of manufacture.

Description

A kind of special-shaped screw
Technical field
The present invention relates to locking part field, particularly relate to a kind of special-shaped screw.
Background technology
Screw in the market starts grooved and is more than 0 degree due to driving angle, easily produces radial force, causes torsion Loss, causes screwdriver and screw grooved mesh degree defective tightness, transmission moment values to reduce;And grooved inwall has cone Degree, face loading power is less than normal, and screwdriver can be caused again easily to skid when the turn of the screw, and damaged screws starts groove, and then occurs Screw can not be screwed into the serious consequence maybe can not back-outed.It is exactly also oily the asking that be just difficult to the twist-on time back-out and can not come Topic.
Summary of the invention
The technical problem that present invention mainly solves is to provide a kind of special-shaped screw, and it is reasonable in design, and simple in construction solves In prior art, screw twist-on is of long duration the most quick detachable and the problem that can not cross oil strain by screw.
For solving above-mentioned technical problem, the technical scheme that the present invention uses is to provide a kind of special-shaped screw, comprising: First body of rod, second body of rod, coiled hair, gathering sill, annular groove and oil-through hole;Described first body of rod is arranged on coiled hair upper surface On;Described second body of rod is arranged on coiled hair lower surface;Described first body of rod is provided with annular groove;Described second body of rod lower end It is provided with screw thread;A gathering sill is offered in any side of described second body of rod;An oil-through hole is offered at described special-shaped screw center.
Preferably, described first body of rod, second body of rod and coiled hair are an entirety;
Preferably, described annular groove has two;
Preferably, described coiled hair is hexagonal;
Preferably, described oil-through hole is through hole, runs through whole special-shaped screw.
The invention has the beneficial effects as follows: present configuration is simple, reasonable in design, installation and removal are convenient easily, have foot Enough intensity and good manufacturability, low cost of manufacture;Reduce when twist-on time length can import lubricating oil by gathering sill Friction, oil-through hole can also be crossed oily moistening to pipe fitting reduction friction simultaneously.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of a kind of special-shaped screw of the present invention;
In accompanying drawing, the labelling of each parts is as follows: 1, first body of rod;2, second body of rod;3, coiled hair;4, gathering sill;5, annular groove; 6, oil-through hole.
Detailed description of the invention
Below in conjunction with the accompanying drawings presently preferred embodiments of the present invention is described in detail, so that advantages and features of the invention energy It is easier to be readily appreciated by one skilled in the art, thus protection scope of the present invention is made apparent clear and definite defining.
Referring to accompanying drawing 1, the embodiment of the present invention includes: first body of rod 1, second body of rod 2, coiled hair 3, gathering sill 4, annular are recessed Groove 5 and oil-through hole 6;Described first body of rod 1 is arranged on coiled hair 3 upper surface;Described second body of rod 2 is arranged on coiled hair 3 lower surface On;Described first body of rod 1 is provided with annular groove 5;Described second body of rod 2 lower end is provided with screw thread;Described second body of rod 2 any A gathering sill 4 is offered in side;An oil-through hole 6 is offered at described special-shaped screw center.
Further, described first body of rod 1, second body of rod 2 and coiled hair 3 are an entirety;
Further, described annular groove 5 has two;
Further, described coiled hair 3 is hexagonal;
Further, described oil-through hole 6 is through hole, runs through whole special-shaped screw.
Present configuration is simple, reasonable in design, and installation and removal are convenient easily, have enough intensity and good technique Property, low cost of manufacture;Reducing friction when twist-on time length can import lubricating oil by gathering sill 4, oil-through hole 6 also may be used simultaneously To cross, oil is moistening reduces friction to pipe fitting.
The foregoing is only embodiments of the invention, not thereby limit the scope of the claims of the present invention, every utilize this Equivalent structure or equivalence flow process that bright description is made convert, or are directly or indirectly used in other relevant technology necks Territory, is the most in like manner included in the scope of patent protection of the present invention.
