Further, the round estrade is fixed with sealing ring far from the end face of the nut head.
Through the above technical solutions, passing through setting sealing in use, the opening of counterbore is pushed against the surface of attached article
Ring enhances the sealing performance after the utility model is tightened.
Further, the nut head is offered far from the end face of the round estrade convenient for turning turning for the nut head
Slot.
Through the above technical solutions, in use, the screwing tools such as spanner are inserted into slot to turning, convenient for turning nut head.
Further, the trench bottom that turns is fixed with elastic component, and the one end of the elastic component far from the round estrade is solid
Surely have for turning the closed sliding sheet of slot for described.
Through the above technical solutions, sliding sheet sliding setting is turning in slot, for avoiding extraneous rainwater from penetrating into turning
Trench bottom.
Further, the sliding sheet edge is fixed with rubber ring.
Through the above technical solutions, rubber ring is used to enhance the waterproof performance of the utility model.
Further, there is chamfering in side of the nut head far from the round estrade along its edge.
Through the above technical solutions, opening up the burr that chamfering is used for away product.
Further, the nut head and the round estrade are all made of stainless steel and are made.
Through the above technical solutions, improving the rust-preventing characteristic of the utility model using stainless steel making nut head and round estrade
Energy.
Compared with prior art, the utility model has the beneficial effects that
(1) by opening up counterbore and tapped blind hole, in use, nut headgear protects screw thread in one end of bolt thread section
Section avoids thread segment impaired, it is ensured that nut head can be backed out smoothly from bolt；
(2) further, by providing self-locking tooth and sealing ring two schemes, it is respectively used to the close of enhancing the utility model
Envelope property and self-locking performance；
(3) further, slot is turned by opening up, the utility model not only can turn face by spanner clamping and back out nut
Head, moreover it is possible to by being inserted into spanner in slot and backing out nut head to turning, increase the mode for removing nut head.

Specific embodiment
In order to keep the purpose of this utility model, technical scheme and beneficial effects clearer, below with reference to embodiment and attached
The utility model is described in further detail for figure, but the embodiments of the present invention is not limited only to this.
Embodiment one
As shown in Figure 1, a kind of nut, including nut head 1,1 one end of nut head are integrally fixed with round estrade 2, nut head 1
It is all made of stainless steel with round estrade 2 to be made, it is ensured that the utility model has good rustless property.1 two sides of nut head open up
Some turns face 3, and convenient for turning nut head 1 by handle, round estrade 2 offers counterbore 4, counterbore 4 far from the side of nut head 1
Bottom offers tapped blind hole 5, and the radius of tapped blind hole 5 is less than the radius of counterbore 4, and end face of the round estrade 2 far from nut head 1 is solid
