Description
Technical field
The invention belongs to mechanical frock field, it is related to a kind of screw, more particularly to a kind of sealing screw.
Technical background
In the prior art after screw is screwed into workpiece for play later stage antirust can in screw edge instillation antirust agent, but
This traditional antirust agent instillation mode often produces antirust agent to be difficult to penetrate into during instillation, or due to screw spiral shell
Line contacts the problem for too closely causing antirust oil to penetrate into thread groove.Traditional screw is prevented from from the aspects of material economy
Rust often results in substantial amounts of antirust agent and wastes, and is unable to reach preferable screw anti-rust action.
On the other hand it is especially extremely strict to the requirement of screw sealing effectiveness in aerospace field, and traditional screw is being twisted
All it is directly to tighten when entering in workpiece or equipment, sealing effectiveness is determined with tightness, but due to workpiece or the mismachining tolerance of equipment
Direct Butt sealing between steel and iron parts is difficult to play absolute sealing.
The content of the invention
It is an object of the invention to overcome the deficiencies in the prior art, and provide that a kind of anti-rust action effect is good, sealing effectiveness
Sealing screw good, easy to operate, rational in infrastructure.
The object of the present invention is achieved like this：A kind of sealing screw, includes screw body, described screw body by
Conventional screw head and screw rod composition, described screw head center are provided with oil filler point, described pitch position longitudinal direction and
Perpendicular to the ground to be provided with oil storage tank, described oil filler point is connected with oil storage tank, is set with perpendicular to the ground on described oil storage tank
Also horizontal vertical is provided with Oil Guide passage on the basis of the oil storage tank put, and described Oil Guide passage penetrates spiral shell in aplysia punctata to external radiation
Bar and ft connection, described oil filler point are T font structures, and supporting are provided with T font plugs with its；
Screw head and screw rod junction are provided with an annular groove, described ring on the screw head downside of the screw body
A sealing ring is provided with connected in star, the lower edge of described sealing ring sealing ring when being put into annular groove exceeds annular
The lower edge of groove.
Described Oil Guide passage sets number and is no less than 1.
Described Oil Guide passage is only provided with one on a cross section for screw rod.
Position relationship is vertical relation between described Oil Guide passage is often two neighboring.
The invention has the advantages that：Oil storage tank first in the longitudinally perpendicular setting of pitch can provide foot
The antirust agent receiving space of amount, the Oil Guide passage radially set on oil storage tank can provide antirust agent extravasation passage, make
Antirust agent flows out from Oil Guide passage, and penetrates into the position that screw flight is connected with thread groove and play optimal antirust or rust protection
Effect.Wherein Oil Guide passage sets and 1 is no less than in quantity, and the depth that can be screwed on workpiece according to screw is configured, and
An Oil Guide passage is only provided with the same cross section of screw rod, antirust agent multi-point, multi-faceted outside can be enable
Ooze out；Furthermore Oil Guide passage is arranged on mechanical skilled worker's aspect per two neighboring perpendicular relation and more facilitates processing.Last oiling
Hole is arranged at screw head upper middle position and is easy to block passage after antirust agent filling is finished, and whole operation process is more simple
Single, convenience, when oil filler point is arranged at T font structures and is used cooperatively with T font plugs in addition, can fill in plug tighter and outer
It is more smooth in sight.
The annular groove set with screw rod junction around screw head on the screw head downside of screw body, can place one
Individual sealing ring can make to be formed between screw head and workpiece or equipment when being screwed into workpiece or equipment in screw body together with it is flexible
Sealing, also has in traditional handicraft and installs sealing ring additional in the screw head position of screw body, but is all directly to add under conventional situation
A sealing ring is filled, is formed between one between the screw head and workpiece or equipment of screw body during screw body is tightened
Gap, and under long-term open-air conditions in the middle of pad sealing ring can produce it is aging so that screw body loosen so as to influence
Screw sealing in itself, in the case that situation continued deteriorates, by the sealing of further influence whole device equipment.But it is logical
Cross and annular groove is set in screw head downside, sealing ring can be placed into annular groove, because sealing ring has pliability in spiral shell
Nail tighten during its volume can be extruded under by whole pressed into groove, therefore between screw head and workpiece or equipment not
Can form gap, therefore the setting of annular groove can not only play preferable sealing effectiveness and not interfere with the tight of screw body also
Degree.

Specific embodiment
Embodiment of the present invention is described further with reference to embodiment.
Embodiment 1
As shown in Fig. 1-6：A kind of sealing screw, includes screw body 1, and described screw body 1 is by the conventional He of screw head 2
Screw rod 3 is constituted, and the described center of screw head 2 is provided with oil filler point 4, and the described center of screw rod 3 is longitudinal and is hung down with ground
Oil storage tank 5 directly is provided with, described oil filler point 4 is connected with oil storage tank 5, with setting perpendicular to the ground on described oil storage tank 5
Also horizontal vertical is provided with Oil Guide passage 6 on the basis of oil storage tank, and logical 6 roads of described Oil Guide are in aplysia punctata to external radiation penetrating screw
3 and ft connection, described oil filler point 4 is T font structures, and supporting is provided with T fonts plug 7 with its；
Screw head 2 and the junction of screw rod 3 are provided with an annular groove 8 on the screw head downside of the screw body 1, it is described
Annular groove 8 in be provided with a sealing ring 9, described sealing ring 9 when being put into annular groove 8 sealing ring 9 it is following
Along beyond the lower edge of annular groove 8.
It is 10 that described Oil Guide passage 6 sets number.
Described Oil Guide passage 6 is only provided with one on a cross section for screw rod 3.
Position relationship is vertical relation between described Oil Guide passage 6 is often two neighboring.
The present invention is when in use：Screw body is screwed into workpiece first, sealing ring receives outer forcing during tightening
Compel volume-diminished, until be fully compressed in annular groove, and continue to tighten screw body and reach tightness requirement, so that sealing
Ring preferably plays screw body with workpiece or the sealing effectiveness of equipment room；Then antirust agent is injected into oil storage tank from oil filler point
Interior, antirust agent is flowed into screw flight by the Oil Guide passage connected with oil storage tank to be had in the space in gap with workpiece thread groove,
Screw thread docking location to each section carries out oil sealing, so as to play rust-proof effect, T fonts is used after antirust agent filling is finished
Plug blocks the oil filler point of T fonts, and whole operation process is finished.
