Description
Technical Field
The utility model relates to a bolt technical field especially relates to an antirust bolt that loses.
Background
Bolts used in the market can be roughly divided into 4 types according to the materials: carbon steel bolts, stainless steel bolts, plastic bolts, and copper bolts. Stainless steel bolts and copper bolts have good mechanical properties but are expensive, and plastic bolts have the characteristics of non-conductivity and rust prevention but bear small torque, so the stainless steel bolts, the plastic bolts and the copper bolts are only used in special occasions, and the most used stainless steel bolts are carbon steel bolts in general.
The carbon steel bolt is simple to process, low in cost and large in bearable torque, and is widely applied to various mechanical connection structures. However, the carbon steel bolts are easily rusted, which makes the bolts difficult to assemble and disassemble and cannot be reused.
Disclosure of Invention
An object of the utility model is to overcome the not enough of above-mentioned technique, provide an antirust bolt, have the advantage that prevents that bolt and screw thread from rustting.
In order to realize the purpose of the utility model, the utility model adopts the technical scheme that:
an anti-corrosion bolt comprises a screw rod and a bolt head, wherein the screw rod is vertically arranged, the bolt head is arranged at the top end of the screw rod, an oil storage cavity is arranged in the bolt head, a through hole is formed in the center of the top of the oil storage cavity, a blocking piece is arranged in the oil storage cavity, a spring is connected between the blocking piece and the inner bottom of the oil storage cavity, the blocking piece is pressed against the inner top surface of the oil storage cavity by the spring, and oil absorption cotton is filled between the blocking piece and the inner bottom surface of the oil storage cavity; the screw rod upper portion periphery is equipped with the lantern ring, the lantern ring top surface is fixed in the bolt head bottom surface, and the inner circle internal diameter of lantern ring equals the screw thread external diameter of screw rod, set up the annular lubrication chamber of round on the inner circle wall of lantern ring, seted up the oil flow passageway in the lantern ring and the bolt head, with lubrication chamber and oil storage chamber intercommunication.
The utility model discloses a further improvement lies in, screw rod, bolt head and lantern ring are integrated into one piece structure.
The utility model discloses a further improvement lies in, separation blade top surface center is equipped with the arch that can plug up the through-hole for prevent lubricating oil from the seepage of through-hole department.
The utility model discloses a further improvement lies in, the lantern ring is narrow round platform shape structure under the upper wide, the top surface diameter of the lantern ring is equal with the bottom surface diameter of bolt head.
The utility model has the advantages that:
the utility model discloses a separation blade, spring, oil absorption cotton and through-hole set up, when the bolt was used, through pressing the separation blade at intervals, make the oil absorption cotton extrude lubricating oil, make lubricating oil get into the lubrication cavity through flowing oil passageway, lubricating oil oozes downwards along the spiral clearance between the thread in the lubrication cavity, realize lubricated rust-resistant, can prevent effectively to rust; in addition, when the lubricating oil volume in the oil storage cavity is not enough, the blocking sheet is pressed downwards by the pressing piece with the diameter smaller than the through hole, then the lubricating oil is injected into the oil storage cavity, the pressing piece is slowly released to enable the oil absorption cotton to fully absorb the lubricating oil, oil can be filled for multiple times for recycling, and the practical service life of the bolt is guaranteed.
