Mother is difficult to dismantle, this just gives repairing or maintenance to bring inconvenience, also will cause the waste of the energy and the pollution of environment, to give
Enterprise brings unnecessary loss.Existing outdoor antirust screw erosion device is usually preforming nut cap, which needs
It to customize, cannot be adjusted according to bolt length to victory inconvenient for use previously according to the diameter of bolt used in flanged joint.This
Under outdoor rain effect after aging, fastening strength decline not can guarantee from beginning to end to outdoor bolt outer common nut cap
Protection, failure easy to damage.
Summary of the invention
For in the prior art, routinely the shortcomings that the nut cap of outdoor antirust screw erosion, the purpose of this utility model exists
It is adjustable, strong applicability of stretching, solid and reliable in providing a kind of outdoor antirust screw erosion device, room can be protected for a long time
Outward flange connects bolt from raindrop erosion.
To achieve the above object, technical solution adopted in the utility model is as follows:
A kind of outdoor antirust screw erosion device, including nut cap, further include rainhat, telescoping tube and magnet:
The rainhat is the cylinder that top is closed, lower part is open, and the lower end of rainhat and the upper end of telescoping tube connect；
The lower end of the telescoping tube and the upper end of nut cap connect；
The nut cap is hollow cylinder, and lower end surface edge is circumferentially arranged with ring side；The rainhat, telescoping tube and
Nut cap coaxial arrangement；
The magnet includes upper magnet and lower magnet, and upper magnet is set to the top of rainhat；Lower magnet is set to nut cap
On ring side.
It is further preferred that the rainhat is the cylindrical body that top is closed, lower part is open, internal cavities can be with bolt
End matches, and plays the role of closed protective bolt, and shape can also be the cylinders such as quadrangular, pentagonal prism.
Further, the nut cap is hollow cylindrical body, and internal cavities can accommodate lower nut, play closed protective
The effect of nut, shape can also be the cylinders such as quadrangular, pentagonal prism.Wherein, the size of rainhat opening, telescoping tube it is interior
The pore size of diameter and nut cap is adapted with bolt, in order to which bolt can pass through rainhat, telescoping tube and nut cap.
Further, the lower magnet number is even number, and central symmetry is set on the ring side of nut cap, is convenient for nut cap
Ring side all directions uniform force on flange and be tightly combined because of magnetic-adsorption.
Further, the lower magnet number is two or four.
Further, the rainhat, telescoping tube and nut cap use stainless steel or engineering plastics, not according to use environment
With selection suitable material.
Further, the magnet is alnico magnets, improves the adsorption capacity of magnet and then increases the tightness of device.
Compared with prior art, the utility model has the following beneficial effects:
1, can be adapted for using telescoping tube connecting rain-proof cap and nut cap since telescoping tube length is adjustable
The bolt of different length, present apparatus strong applicability；
2, the upper magnet being arranged on tarpaulin, can bolt pass through nut cap and telescoping tube withstand after rainhat with bolt
End securely attracts；The lower magnet being arranged on the ring side of nut cap can make the present apparatus securely and various aspects uniform force because of magnetic
Power is adsorbed on flange, not only ensure that the compactness of sealing, but also fastening strength caused by material aging can be overcome to decline；
3, present apparatus structure is simple, easily manufactured at low cost, and it is convenient for disassembly and assembly can be used for multiple times, therefore can be widely applied
In in the antirust screw erosion protection of outdoor flanged joint.
