Abstract

The utility model relates to a full nut, which is composed of a nut, a flat washer and a spring washer. A plurality of convex feet and flanges are protruded on the bottom face and top face of the nut, and the distance from the convex feet and the flanges on the bottom face to the center is basically equal to the distance from the convex feet and the flanges on the top face to the center. The flat washer can be rotatablely sheathed and hung on the convex feet by the inner edge, the spring washer is a circular ring with a fanning strip inwardly protruded that at the relative position of the inner edge of the spring washer, and the spring washer which is arranged on the top surface of the nut is rotatablely grasped through the flange. The utility model has the advantages that because the nuts, flat washer and spring washer are integrated, the time of mounting and dismounting is decreased, and the damage of the flat washer to a substrate is reduced; the utility model is convenient for automation and high-lift operation, can avoid the loss of the washers, and can eliminate the gluing of the flat washer and the substrate while being disassembled.

Description

Full nut

The utility model relates to a kind of nut, especially relates to a kind of Full nut that has packing ring.

Existing nuts and washers generally all is separately to make, and cooperates in use then.Nut has fastening function, and spring washer has locking functions, and plain washer has anti-fastening surface scratch and increases the pressure-bearing surface function.But because they are independently, need when therefore assembling to install in proper order respectively one by one, assembling is very time-consuming like this, and packing ring is easy to lose; In addition, the long-term contact with substrate of plain washer can be bonding and not quick detachable.

The purpose of this utility model be with packing ring with nut built in.

The utility model is a kind of Full nut, and it comprises a nut and a plain washer, is provided with outstanding convex annular pin on the bottom surface of described nut and apart from the basic equidistance of its center line place, and described plain washer overlaps rotationally by its inner rim and hangs on the described protruding pin.

The utility model also comprises a spring washer, on the end face of described nut and apart from the basic equidistance of its center line place, be provided with the annular flange flange of outstanding inside turnover, described spring washer is one to have the annulus of the two inwardly outstanding and fanning strips that fuse within it on the edge relative position, and described spring washer is placed on the described nut end face and by described flange described annulus is clamped on the described nut.

The utility model has the advantages that owing to needed to divide the action of three mounting or dismounting only to need a step to finish now originally therefore reduced the mounting or dismounting time, this has significant effect for large-scale industrial production; Because the area of contact of nut and plain washer reduces, and the suffered torsion of plain washer is reduced, therefore when nut rotated, plain washer can not rotate, and plain washer only produces pressure to substrate, and the surface failure to substrate reduces greatly like this; Because packing ring is connected on the nut, avoided packing ring to lose, and plain washer and substrate bonding when having got rid of dismounting; Because nut, plain washer, spring washer three are integrated, automated job and high-lift operation have therefore been made things convenient for.

Below in conjunction with accompanying drawing, most preferred embodiment of the present utility model is described in detail, therefrom can see the more advantage of the utility model.

Fig. 1 is a sectional view of the present utility model;

Fig. 2 is the plan view of Fig. 1;

Fig. 3 is the sectional view that the protruding pin of the utility model has another form.

Now referring to Fig. 1 and 2, the utility model comprises a nut 1, a plain washer 2 and a spring washer 3.And on the bottom surface of nut 1 near center screw and outwards outstanding downwards convex annular pin 4 is set apart from the basic equidistance of its center line place, in addition, also can be on the end face of nut 1 near outer rim and the annular flange flange 5 of outstanding inside turnover is set apart from the basic equidistance of its center line place, plain washer 2 overlaps rotationally by its inner rim and hangs on the protruding pin 4.Spring washer 3 is one to have the annulus of the two inwardly outstanding and fanning strips 6 that fuse within it on the edge relative position, and it is placed on nut 1 end face and by flange 5 annulus is clamped on the nut 1, and the central angle of each fanning strip 6 is preferably 90 °.

Now referring to Fig. 1 and Fig. 3, protruding pin 4 can have two kinds of shapes according to the size of nut 1 and the thickness of plain washer 2.For big nut, thick washer, 4 one-tenth on protruding pin is outward-dipping downwards, as shown in Figure 1; For primary nut, thin packing ring, protruding pin 4 cambers outwards stick up, as shown in Figure 3.

Claims

1, a kind of Full nut, it comprises a nut and a plain washer, it is characterized in that, is provided with outstanding convex annular pin on the bottom surface of described nut and apart from the basic equidistance of its center line place, described plain washer overlaps rotationally by its inner rim and hangs on the described protruding pin.

2, Full nut as claimed in claim 1, it is characterized in that, it also comprises a spring washer, on the end face of described nut and be provided with the annular flange flange of the inside turnover of protrusion apart from the basic equidistance of its center line place, described spring washer is one to have the annulus of the two inwardly outstanding and fanning strips that fuse within it on the edge relative position, and described spring washer is placed on the described nut end face and by described flange described annulus is clamped on the described nut.
