Abstract
The invention discloses a screw bolt with a built-in lubricating oil duct. The screw bolt comprises a screw head and a screw rod, wherein the screw head is a hexagonal screw head of which the cross section is in the shape of a regular hexagon; the bottom of the screw head is fixedly connected with the screw rod; the screw rod is in a cylindrical structure; the vertical central axis of the screw rod and the central axis of the screw head are on one line; the external surface of the screw rod is provided with a thread; a slope oil duct is arranged inside the screw head; the slope oil duct forms a cambered oil groove on the surface of the screw head; the slope oil duct forms an outlet which leads to the thread on the surface of the screw rod; and lubricating oil can perform lubrication along the thread. According to the invention, the screw bolt can be lubricated at any time, thereby avoiding the conditions of rusting and passivation in the long-term usage process of the screw bolt. The added lubricating oil is accurately led to the thread groove on the screw rod surface through the slope oil duct, and thus, the screw bolt is convenient and practical.
Description
Technical field
The present invention relates to hardware field, particularly relate to the bolt of establishing oil leab in a kind of.
Background technology
Bolt is the one of machine components, the cylindrical threaded securing member of adapted nut, by head and a screw rod class securing member dimerous, need coordinate with nut, for being fastenedly connected two parts with through hole, but get rusty easily and passivation in the long-term use procedure of bolt, need to add lubricant, and by the time bolt being lubricated to agent interpolation, often lubricating oil is directly poured on bolt, not only can cause a large amount of wastes, also may cause interpolation inhomogeneous, significant points can not get lubricated.
Summary of the invention
The technical problem that the present invention mainly solves is to provide the bolt of establishing oil leab in a kind of, can be lubricated work to bolt at any time, avoid getting rusty in the long-term use procedure of bolt and the situation of passivation, it is by domatic oil duct accurately on the thread groove on guide spiro rod surface, convenient and practical when lubricating oil adds.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: the bolt of establishing oil leab in a kind of is provided, it is characterized in that, comprising: spiral shell head, screw rod; Described spiral shell head is that its lateral cross section is orthohexagonal hexagonal spiral shell head, and spiral shell head bottom is fixedly connected with described screw rod; Described screw rod is cylindrical structure, the vertical central shaft of screw rod and the central shaft of described spiral shell head are point-blank, on screw rod outer surface, be provided with screw thread, described spiral shell head inside is provided with a domatic oil duct, described domatic oil duct forms an arc oil groove on the surface of spiral shell head, described domatic oil duct forms on the screw thread of the screw surface described in an export orientation, and lubricating oil can be lubricated along screw thread.
In a preferred embodiment of the present invention, the diameter of described domatic oil duct is 1-5mm.
In a preferred embodiment of the present invention, the angle that described domatic oil duct and described screw rod form is 30 °-60 °.
In a preferred embodiment of the present invention, the width of described arc oil groove is 1-5mm.
In a preferred embodiment of the present invention, the screw thread on described screw rod is arranged on the exit of described domatic oil duct.
The invention has the beneficial effects as follows: the present invention can be lubricated work to bolt at any time, avoid getting rusty in the long-term use procedure of bolt and the situation of passivation, by domatic oil duct accurately on the thread groove on guide spiro rod surface, convenient and practical when lubricating oil adds.
Brief description of the drawings
In order to be illustrated more clearly in the technical scheme in the embodiment of the present invention, below the accompanying drawing of required use during embodiment is described is briefly described, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing, wherein:
Fig. 1 is the structural representation that the present invention establishes bolt one preferred embodiment of oil leab in a kind of;
Fig. 2 is the top view of described spiral shell head.
In accompanying drawing, the mark of each parts is as follows: 1-spiral shell head, 2-screw rod, 3-screw thread, 4-domatic oil duct, 5-arc oil groove, 6-outlet.
Detailed description of the invention
To the technical scheme in the embodiment of the present invention be clearly and completely described below, obviously, described embodiment is only a part of embodiment of the present invention, instead of whole embodiment. Based on the embodiment in the present invention, those of ordinary skill in the art, not making all other embodiment that obtain under creative work prerequisite, belong to the scope of protection of the invention.
Refer to Fig. 1,2, the embodiment of the present invention comprises:
In establish the bolt of oil leab, it is characterized in that, comprising: spiral shell head 1, screw rod 2; Described spiral shell head 1 is that its lateral cross section is orthohexagonal hexagonal spiral shell head, and spiral shell head 1 bottom is fixedly connected with described screw rod 2; Described screw rod 2 is cylindrical structure, the vertical central shaft of screw rod 2 and the central shaft of described spiral shell head 1 are point-blank, on screw rod 2 outer surfaces, be provided with screw thread 3, described spiral shell head 1 inside is provided with a domatic oil duct 4, described domatic oil duct 4 forms an arc oil groove 5 on the surface of spiral shell head 1, described domatic oil duct 4 forms on the screw thread 3 on described screw rod 2 surfaces of outlet 6 guiding, and lubricating oil can be lubricated along screw thread 3.
The diameter of described domatic oil duct 4 is 1-5mm.
Described domatic oil duct 4 is 30 °-60 ° with the angle that described screw rod 2 forms, and domatic oil duct 4 arranges different angles of inclination.
The width of described arc oil groove 5 is 1-5mm, ensures that lubricating oil can easily inject in spiral shell head.
Screw thread 3 on described screw rod 2 is arranged on outlet 6 places of described domatic oil duct 4.
Operation principle of the present invention: while adding lubricating oil, arc oil groove 5 by lubricating oil from spiral shell head 1 injects, lubricating oil flow to outlet 6 places along domatic oil duct 4, last lubricating oil is postponed and is flow to screw thread 3 grooves of screw rod 2 from exporting 6, addition manner makes can not cause waste accurately, and bolt can be because long-term use got rusty and passivation after interpolation lubricating oil.
The present invention can be lubricated work to bolt at any time, avoids getting rusty in the long-term use procedure of bolt and the situation of passivation, by domatic oil duct accurately on the thread groove on guide spiro rod surface, convenient and practical when lubricating oil adds.
