A chamber is equipped with, the connecting rod other end is fixedly connected with chock plug, and the permanent magnet is arranged in chamber；The utility model causes
Permanent magnet is not easily to fall off during machine run, and permanent magnet absorption iron filings effect when impurity is more preferable, slows down the mill of each rotatable parts
Damage, extends the service life of equipment, effectively reduces production cost, in addition, the utility model also has good seal performance,
Installation easy to disassemble can not only adsorb the impurity such as iron filings, but also can store the impurity of absorption, afterwards can be with
Disassembly, cleaning, it is more practical.
But the sealing effect of above-mentioned plug screw is general, while the impurity adsorbed is not easy discharge, it is necessary to plug screw be unloaded, Cai Nengqing
The impurity adsorbed on plug screw is washed, operation is cumbersome.
Utility model content
The purpose of this utility model is to provide a kind of magnetic Leakproof plug screws, understand that impurity is convenient, sealing effect can basis
Spiro pluging hole size is changed, and sealing effect is good.
For this purpose, the utility model uses following technical scheme：
A kind of magnetism Leakproof plug screw includes the plug screw seat and plug screw bar of integrationization processing, is provided on the plug screw bar
External screw thread, one end of plug screw bar connection plug screw seat set diameter to be less than the changeover portion of plug screw bar, the changeover portion outer circle according to
Secondary to be set with the first rubber ring, magnetic rings and the second rubber ring, the plug screw seat is set with respect to the other end indent of plug screw bar
It is fluted, the through hole communicated with groove is provided in the plug screw bar, one end that the through hole is located at plug screw bar outer end is provided with
Magnetic plate seals the outer end of through hole, and the magnetic plate outer circle sets the insulating coating that is magnetic.
Wherein, the overall diameter of first rubber ring, magnetic rings and the second rubber ring set after changeover portion outer circle is more than
Plug screw shank diameter 0.5-1mm.
Wherein, first rubber ring is the oily intumescent rubber ring of chance.
Wherein, the magnetic rings are process for elastic magnetic sheet.
Wherein, the through hole is located at one end of groove and is provided with sealing cover.
Wherein, it is provided with the connecting rod being connected with sealing cover on the magnetic plate.
Wherein, the plug screw seat be located at plug screw bar one end be provided with diameter be more than changeover portion diameter annular groove.
Wherein, it is inlaid with sealing ring in the annular groove.
The beneficial effects of the utility model：A kind of magnetism Leakproof plug screw, the oil adsorbed using the first rubber ring are expanded,
Drive magnetic rings outwardly against, the second rubber ring is pressed on the hole wall of blocking, magnetic rings with block hole form magnetic suction
It is attached, to the second rubber ring and pressure is added, strengthens sealing effect, while passes through magnetic plate adsorbing contaminant.
Description of the drawings
Fig. 1 is the structure diagram of the utility model.
Specific embodiment
The technical solution of the utility model is further illustrated with reference to Fig. 1 and by specific embodiment.
A kind of magnetism Leakproof plug screw includes the plug screw seat 1 and plug screw bar 2 of integrationization processing, is set on the plug screw bar 2
There is an external screw thread, the plug screw bar 2 connects the changeover portion that one end of plug screw seat 1 sets diameter to be less than plug screw bar 2, outside the changeover portion
Circle is set with the first rubber ring 3,4 and second rubber ring 5 of magnetic rings, first rubber ring 3,4 and second rubber of magnetic rings successively
Rubber ring 5 is sleeved on the overall diameter after changeover portion outer circle and is more than 2 diameter 0.5-1mm of plug screw bar, and rubber ring has elasticity, works as magnetic rings
4 with blocked hole wall adsorb when, by the second rubber ring 5 outwardly against, strengthen sealing performance.
The plug screw seat 1 sets fluted 11 with respect to the other end indent of plug screw bar 2, is provided in the plug screw bar 2
The through hole 21 communicated with groove 11, one end that the through hole 21 is located at 2 outer end of plug screw bar are provided with the sealing through hole 21 of magnetic plate 6
Outer end, the iron that magnetic plate 6 can be adsorbed in fuel tank cut impurity, and 6 outer circle of magnetic plate sets the insulating coating that is magnetic, prevents
Magnetic plate 6 generates adsorption capacity with through hole 21, it is difficult to depart from.
