Description
Technical field
The utility model relates to bolt technical field, refers to a kind of antirust bolt especially.
Background technique
The bolt that market uses can be divided into 4 kinds substantially according to material: carbon steel bolt, stainless steel bolt, plastic bolt and copper bolt.The various satisfactory mechanical property of stainless steel bolt and copper bolt but cost is more expensive, plastic bolt has non-conductive, antirust characteristic but the moment of torsion born is less, so stainless steel bolt, plastic bolt and copper bolt are used only in special occasions, generally use maximum still carbon steel bolts.
The processing of carbon steel bolt is simple, with low cost, and the moment of torsion that can bear is comparatively large, is widely used in the structure of various mechanical connection.But carbon steel bolt gets rusty easily, the process that the bolt particularly worked under the larger occasion of humidity or outdoor environment gets rusty is very fast, causes the dismounting of bolt difficulty and cannot reuse.
In order to technical solution problem, prior art proposes on bolt shank, to arrange oil storage hole or in the inside and outside portion of bolt shank, offer hydraulic fluid port on oil duct and oilhole and bolt head respectively and is interconnected.But prior art exists shortcoming: after the rust preventive oil 1, in oil storage hole is finished, need again to dismantle to add rust preventive oil; And staff does not know when the rust preventive oil in oil storage hole is finished yet; 2, on bolt head, do not set up defences dirt, waterproof of hydraulic fluid port enters the Sealing of oil duct; After of long duration, dust can be deposited in oil duct, causes stopping up of oil channel; Now, most of rainwater is acid, and rainwater enters in oil duct, can from internal corrosion bolt, causes bolt to become rusty extremely, not quick detachable, even ruptures.
Model utility content
The utility model proposes a kind of antirust bolt, to solve in prior art the convenient and rainwater in bolt oiling portion or dust easily enters in oil duct, cause stopping up of oil channel or bolt to become rusty dead problem.
The technical solution of the utility model is achieved in that a kind of antirust bolt, comprise bolt head and bolt shank, described bolt head is connected with the upper end of described bolt shank, described bolt shank comprises polished rod body and threaded body, described polished rod body and described threaded body integrally manufactured, described bolt head is provided with pouring orifice, and described pouring orifice is communicated with the oil duct being arranged on bolt shank inside; Described bolt shank is provided with oilhole and this oilhole is communicated with described oil duct; Described bolt head is provided with connecting groove, is provided with the diaphragm seal for sealed oil-filling mouth in described connecting groove; Described diaphragm seal moves along the wall of connecting groove;
Axis along bolt shank is provided with elastic component and one end of this elastic component is connected with described bolt head; The other end of described elastic component is connected with sealing gasket, and described sealing gasket is conflicted with described bolt shank and is connected.
Together with described sealing gasket and described bolt shank are conflicted and connected and refer to that the outer wall of sealing gasket touches with the outer wall of bolt shank, but be not link together, sealing gasket can independently moving.
Preferably, the central axis of the central axis of described elastic component and described bolt shank at grade.
Preferably, described elastic component has some, and arranges along the radial uniform intervals of the outer wall of bolt shank.
Preferably, described elastic component has 4.
Preferably, described diaphragm seal is provided with groove.
Preferably, described oilhole is arranged on polished rod body.
Preferably, described elastic component is torsion spring.
The beneficial effect that the utility model possesses:
1, diaphragm seal outwards shifts out from connecting groove, can sealed oil-filling mouth, prevents dust or water from entering in oil duct, corrosion bolt or blocking oil duct;
2, open diaphragm seal and can know the consumption knowing the inner rust preventive oil of oil duct; When consumption is few, directly can drip rust preventive oil from hydraulic fluid port;
3, sealing gasket can prevent rainwater from entering further, strengthening stud antirust function;
4, when tighting a bolt, elastic component by sealing gasket along with the power in the direction that tights a bolt rotate and to be wrapped on bolt shank and formed one with the opposite force tighted a bolt; When demounting bolt, the power of opposite force and unthread bolts is same direction force, especially in the dead or not easily detachable situation of bolt rust, can alleviate dismounting difficulty.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the utility model structural representation;
Fig. 2 is the structural representation tighted a bolt;
Fig. 3 is the partial enlarged drawing of Fig. 1.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technological scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figure 1, a kind of antirust bolt, comprise bolt head 1 and bolt shank 2, bolt head 1 is connected with the upper end of bolt shank 2.Bolt head 1 is a kind of interior hexagon bolt head.Bolt shank 2 comprises polished rod body 21 and threaded body 22, and polished rod body 21 is integrally manufactured with threaded body 22.Pouring orifice 4 is arranged in the interior hex-shaped recess 3 of bolt head 1.Pouring orifice 4 is communicated with the oil duct 5 being arranged on bolt shank 2 inside.Polished rod body 21 is provided with oilhole 6, and oilhole 6 is communicated with oil duct 5.Oilhole 6 also can be arranged on threaded body 22.See Fig. 3, bolt head 1 has a connecting groove 10, and diaphragm seal 9 is arranged in connecting groove 10.Diaphragm seal 9 moves around along the wall of connecting groove 10, realizes the closedown to pouring orifice 4 and unlatching.Diaphragm seal 9 is also provided with a groove 11, convenient unlatching or closedown diaphragm seal 9.
