Abstract
The utility model discloses an interior bolt of establishing lubricated oil duct, including spiral shell head, screw rod, the spiral shell head be its transverse section for regular hexagon's hexagonal drive head, spiral shell head bottom fixed connection the screw rod, the screw rod be the cylinder structure, the vertical center pin of screw rod with the center pin of spiral shell head is provided with the screw thread point -blank on the screw rod surface, the spiral shell head inside be provided with a domatic oil duct, the domatic oil duct at the arc oil groove of formation on the surface of spiral shell head, the domatic oil duct form an export orientation the screw thread on screw rod surface on, lubricating oil can lubricate along the screw thread. In this way, the utility model discloses can be at any time to the bolt work of lubricating, avoid getting rusty in the long -term use of bolt and the circumstances about passivate, lubricating oil passes through the surperficial thread groove of the accurate uide screw of domatic oil duct when adding on, convenient and practical.
Description
Technical field
This utility model relates to hardware field, particularly relate to a kind of in set the bolt of oil leab.
Background technology
Bolt is the one of machine components, the threaded securing member of cylinder of adapted nut, by a head and screw rod class securing member dimerous, need and nut screw connection, for being fastenedly connected two parts with through hole, but get rusty easily during bolt life-time service and be passivated, need to add lubricant, and by when bolt being lubricated agent and adding, often lubricating oil is directly poured on bolt, not only result in a large amount of waste, it is also possible to causing interpolation uneven, significant points can not get lubricated.
Utility model content
This utility model mainly solving the technical problems that provide a kind of in set the bolt of oil leab, at any time bolt can be lubricated work, situation about getting rusty during avoiding bolt life-time service and be passivated, by on the thread groove on domatic oil duct guide spiro rod surface accurately when lubricating oil adds, convenient and practical.
For solving above-mentioned technical problem, the technical scheme that this utility model uses is: provide a kind of in set the bolt of oil leab, it is characterised in that including: screw head, screw rod；Described screw head be its lateral cross section be orthohexagonal hexagonal screw head, bottom screw head fixing connect described in screw rod；Described screw rod is cylindrical structure, the vertical central shaft of screw rod is with the central shaft of described screw head point-blank, it is provided with screw thread on screw rod outer surface, described screw head is internally provided with a domatic oil duct, described domatic oil duct forms an arc oil groove on the surface of screw head, described domatic oil duct is formed on the screw thread of the screw surface described in an export orientation, and lubricating oil can be lubricated along screw thread.
In one preferred embodiment of this utility model, a diameter of 1-5mm of described domatic oil duct.
In one preferred embodiment of this utility model, the angle that described domatic oil duct is formed with described screw rod is 30 °-60 °.
In one preferred embodiment of this utility model, the width of described arc oil groove is 1-5mm.
In one preferred embodiment of this utility model, the described screw thread on screw rod is arranged on the exit of described domatic oil duct.
The beneficial effects of the utility model are: this utility model can be lubricated work to bolt at any time, situation about getting rusty during avoiding bolt life-time service and be passivated, by on the thread groove on domatic oil duct guide spiro rod surface accurately when lubricating oil adds, convenient and practical.
Accompanying drawing explanation
In order to be illustrated more clearly that the technical scheme in this utility model embodiment, in describing embodiment below, the required accompanying drawing used is briefly described, apparently, accompanying drawing in describing below is only embodiments more of the present utility model, for those of ordinary skill in the art, on the premise of not paying creative work, it is also possible to obtain other accompanying drawing according to these accompanying drawings, wherein:
Fig. 1 be this utility model a kind of in set the structural representation of bolt one preferred embodiment of oil leab；
Fig. 2 is the top view of described screw head.
In accompanying drawing, the labelling of each parts is as follows: 1-screw head, 2-screw rod, 3-screw thread, 4-domatic oil duct, 5-arc oil groove, 6-export.
Detailed description of the invention
Technical scheme in this utility model embodiment will be clearly and completely described below, it is clear that described embodiment is only a part of embodiment of the present utility model rather than whole embodiments.Based on the embodiment in this utility model, all other embodiments that those of ordinary skill in the art are obtained under not making creative work premise, broadly fall into the scope of this utility model protection.
Refer to Fig. 1,2, this utility model embodiment includes:
The bolt of oil leab is set, it is characterised in that including: screw head 1, screw rod 2 in a kind of；Described screw head 1 be its lateral cross section be orthohexagonal hexagonal screw head, bottom screw head 1 fixing connect described in screw rod 2；Described screw rod 2 is cylindrical structure, the central shaft of the vertical central shaft of screw rod 2 and described screw head 1 is point-blank, it is provided with screw thread 3 on screw rod 2 outer surface, described screw head 1 is internally provided with a domatic oil duct 4, described domatic oil duct 4 forms an arc oil groove 5 on the surface of screw head 1, described domatic oil duct 4 forms an outlet 6 and guides on the screw thread 3 on described screw rod 2 surface, and lubricating oil can be lubricated along screw thread 3.
A diameter of 1-5mm of described domatic oil duct 4.
The angle that described domatic oil duct 4 and described screw rod 2 are formed is 30 °-60 °, and domatic oil duct 4 arranges different angles of inclination.
The width of described arc oil groove 5 is 1-5mm, it is ensured that lubricating oil can easily inject in screw head.
The described screw thread 3 on screw rod 2 is arranged at the outlet 6 of described domatic oil duct 4.
Utility model works principle: during oil addition, lubricating oil arc oil groove 5 from screw head 1 is injected, lubricating oil flow to export at 6 along domatic oil duct 4, last lubricating oil is postponed screw thread 3 groove flowing to screw rod 2 from outlet 6, addition manner makes not result in waste accurately, and bolt will not get rusty due to life-time service and be passivated after oil addition.
This utility model can be lubricated work to bolt at any time, it is to avoid the situation got rusty during bolt life-time service and be passivated, by the thread groove on domatic oil duct guide spiro rod surface accurately when lubricating oil adds, convenient and practical.
The foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every equivalent structure utilizing this utility model description to be made or equivalence flow process conversion; or directly or indirectly it is used in other relevant technical field, the most in like manner it is included in scope of patent protection of the present utility model.
