The cover body is connected with the nut through the barb ring, so that the damage of the groove is avoided. But because the barbed loop is easily damaged, it does not protect once it is damaged.

SUMMERY OF THE UTILITY MODEL

Not enough to prior art exists, the utility model aims to provide a novel screw that fluting is not fragile.

In order to achieve the above purpose, the utility model provides a following technical scheme: including the nail body and the nut that are connected, the nut includes the nut body, is equipped with the protection piece on the nut body, is equipped with the protection hole on the protection piece, is equipped with on the nut body to twist the turn trough, and still the dismantlement is connected with sealed piece in the protection hole is in order being suitable for to prevent to twist the turn trough and damage.

Furthermore, the protective block is also provided with a positioning groove which is communicated with the protective hole, and the sealing block is also provided with an elastic positioning strip which is matched with the positioning groove.

Further, the inner wall in protection hole and the inner wall of constant head tank all cover and have self-lubricating layer.

Furthermore, a lifting lug is arranged on the sealing block.

Furthermore, the elastic positioning strip is made of wear-resistant rubber.

Further, the protection hole may be circular or regular polygonal.

Contrast prior art not enough, the utility model provides a beneficial effect that technical scheme brought: when the novel anti-corrosion device is used, when the screw is installed in place, the sealing block is placed into the protective hole, so that the rainwater can be effectively prevented from corroding the twisting groove, the damage to the twisting groove caused by the twisting groove is avoided, and meanwhile, the sealing block is simple in structure and not easy to damage.

The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.

The present invention is further described with reference to fig. 1.

A novel screw comprises a screw body 12 and a screw cap 11 which are connected, wherein the screw cap 11 comprises a screw cap body 111, the screw cap body 111 is provided with a protective block 112, the protective block 112 is provided with a protective hole, the screw cap body 111 is provided with a screwing groove 13, and a sealing block 2 can be detachably connected in the protective hole so as to be suitable for preventing the screwing groove 13 from being damaged; twist the rotor 13 and be a straight flute or cross recess in order to be suitable for the screwdriver to screw up or the screw of unscrewing, when using, when the screw installation targets in place, put into to the guard hole with sealed piece 2, consequently can effectually avoid the rainwater to the corruption of twisting rotor 13, avoid twisting the damage that rotor 13 consequently caused, sealed piece 2 simple structure simultaneously, it is not fragile, the shape phase-match in sealed piece 2 and guard hole.

Further, still be equipped with the constant head tank on the protection piece 112, the constant head tank with the protection hole communicate, still be equipped with on the sealed piece 2 with the elastic positioning strip 21 of constant head tank looks adaptation, consequently when elastic positioning strip 21 is located the constant head tank, can effectually avoid the problem that sealed piece 2 drops to take place.

Further, the inner wall in protection hole and the inner wall of constant head tank all cover and have self-lubricating layer, and self-lubricating layer is the polytetrafluoroethylene material, can effectually reduce the friction, consequently can effectual extension elastically positioned strip's life, keeps sealed effect.

Furthermore, the sealing block 2 is provided with a lifting lug 22, so that the sealing block 2 is more convenient to disassemble.

Furthermore, the elastic positioning strip 21 is made of wear-resistant rubber, so that the wear is not easy to occur.

Further, the protection hole may be a circle or a regular polygon, and when the protection hole is a regular polygon, for example, a regular hexagon, the screw may be mounted and dismounted when the screwing groove 13 is damaged, so that the use is convenient.

The twisting groove 13 is a groove in the background technology.
