Abstract
The utility model discloses a screw, it includes: spiral shell head and screw rod, the spiral shell head links to each other with the screw rod, the spiral shell head is equipped with a fixed orifices all around in four directions respectively, spiral shell head center is equipped with one and crosses the oilhole, and link up the screw rod bottom always, be equipped with the permeability hole on the screw rod outer wall, and permeability hole and cross the oilhole and link up. The utility model discloses simple structure reasonable in design uses the fixed orifices can prevent the screw landing, crosses the oilhole simultaneously and can pass through lubricating oil with the permeability hole, lubricated screw and interfacing part to reduce friction makes things convenient for the staff to dismantle.
Description
Technical field
The utility model is related to fastener areas, more particularly to a kind of screw.
Background technology
Screw generally comprises the body of rod, the threaded portion being formed in the outer rim of the body of rod and the taper for being formed in body of rod tail end
Head.Current screw thread when in use, because threaded portion is in bar shape, so perpendicular shape between threaded portion and workpiece, so,
When using, relatively arduously, simultaneously as screw is after being screwed into workpiece, workpiece can produce certain miscellaneous bits, and
Miscellaneous bits can be rested in the gap in adjacent thread portion, so as to increased the frictional force between screw and workpiece.In view of this, having must
Existing screw is improved to solve the above problems.
Utility model content
The utility model is mainly solving the technical problems that provide a kind of screw, its is reasonable in design, simple structure, solves
Part problem easy to fall off, not easy to remove in the prior art.
In order to solve the above technical problems, the technical scheme that the utility model is used is to provide a kind of screw, it includes：
Screw head and screw rod；The screw head is connected with screw rod；The screw head is all around respectively equipped with a fixing hole on four direction；It is described
Screw head center is provided with an oil-through hole, and penetrates into screw rod bottom always；The screw rod outer wall is provided with permeability hole, and permeability hole with
Oil-through hole insertion.
Preferably, the permeability hole is no less than two.
Preferably, the screw rod outer wall is provided with screw thread.
The beneficial effects of the utility model are：The utility model simple structure is reasonable in design, can be prevented using fixing hole
Screw slides, while oil-through hole can lubricate screw and interfacing part with permeability hole by lubricating oil, so that reduce friction, and it is convenient
Staff dismantles.
Brief description of the drawings
Fig. 1 is a kind of schematic diagram of screw of the utility model；
The mark of each part is as follows in accompanying drawing：1st, screw head；2nd, screw rod；3rd, fixing hole；4th, oil-through hole；5th, permeability hole.
Specific embodiment
Preferred embodiment of the present utility model is described in detail below in conjunction with the accompanying drawings, so that advantage of the present utility model
Can be easier to be readily appreciated by one skilled in the art with feature, it is apparent clear and definite so as to be made to protection domain of the present utility model
Define.
Accompanying drawing 1 is referred to, the utility model embodiment includes：Screw head 1 and screw rod 2；The screw head 1 is connected with screw rod 2；Institute
State screw head 1 and be all around respectively equipped with a fixing hole 3 on four direction；The center of the screw head 1 is provided with an oil-through hole 4, and always
Penetrate into the bottom of screw rod 2；The outer wall of the screw rod 2 is provided with permeability hole 5, and permeability hole 5 and the insertion of oil-through hole 4；The permeability hole 5
No less than two；The outer wall of the screw rod 2 is provided with screw thread.
In use, screw with pipe fitting is fixed after, in order to prevent screw from sliding, by the twist-on spiral shell of fixing hole 3
Nail, gives screw one opposite power, so as to further strengthen fixed screw；When screw is long with to the pipe fitting Connection Time and is difficult
During dismounting, lubricating oil can be permeated by oil-through hole 4 and permeability hole 5, screw is reduced friction with interfacing part, so that side
Just staff's dismounting.
Embodiment of the present utility model is the foregoing is only, the scope of the claims of the present utility model is not thereby limited, it is every
The equivalent structure or equivalent flow conversion made using the utility model description, or directly or indirectly it is used in other phases
The technical field of pass, is similarly included in scope of patent protection of the present utility model.
