Abstract

The utility model discloses a positioning nut, which comprises a nut body (1) and a central screwed hole (2), wherein an axial blind hole (3) is arranged inside the inner wall at one side of the nut body; the open end of the axial blind hole is arranged at the positive end face of the nut body; the lower end of the axial blind hole is provided with screw thread; a radial slot (4) is also arranged inside the nut body; the opening of the radial slot is arranged at the outer lateral wall at one side of the nut body provided with the axial blind hole; the radial slot (4) also cut off the axial blind hole (3) and the depth of the radial slot is larger than the radius of the nut. Compared with the prior art, the positioning nut has the advantages that when the nut needs to be positioned at certain position of a bolt, an upper flake on the nut body is bent, compacted and tightly fastened on a lower thick seat sheet of the nut by a screw, therefore, the nut can not move, so as to prevent the nut from being loosened and ensure the normal running and normal operation of the machinery and the machine.

Description

Setscrew nut

Technical field:

The utility model relates to a kind of nut, specifically is a kind of setscrew nut.

Background technique:

Existing plain nut is very extensive for the fastening applications of general stationary thing, uses also very convenient.But its existence adjusting polarization is poor and the defective of less stable, and nut tends to produce loosening, brings very big insecurity for Work machine or machine.Particularly on some large-scale Work machines or machine, owing to the rotation of machine and inside and outside vibrations, often need to adjust the position of adapted nut, and nut is fixed on a certain position, with normal operation and the operation that ensures machinery or machine.This just requires the nut of institute's adapted not only fastening function will be arranged, and also needs locating function preferably.

The model utility content:

The technical problems to be solved in the utility model is, a kind of fastening preferably function that not only has is provided, and also has the setscrew nut of locating function preferably.

Technical solution of the present utility model is that a kind of setscrew nut with following structure is provided.This nut, comprise nut body and screwed hole of centre, it is characterized in that, be provided with an axial blind hole in the sidewall of nut body one side, the opening end of axial blind hole is arranged on the upper-end surface of nut body, and the hypomere of axial blind hole is provided with screw thread, in nut body, also be provided with a radial groove, the opening of radial groove is arranged on the outer side wall of the nut body that is equipped with axial blind hole one side, and radial groove also cuts off axial blind hole, and the degree of depth of radial groove is greater than the nut radius.

After adopting above structure, compared with prior art, the utility model setscrew nut has the following advantages:

Owing to be provided with an axial blind hole in the sidewall of nut body one side, the hypomere of axial blind hole is provided with screw thread, also is provided with a radial groove in nut body, and radial groove also cuts off axial blind hole, and the degree of depth of radial groove is greater than the nut radius; Radial groove cuts into thin slice and down thick seat sheet with nut, when nut need be located in a certain position of bolt, be inserted in the radial blind holes on the nut body with screw, last thin slice on the nut body is bent and be pressed on the following thick seat sheet of nut by screw, screw is fastened on the screw thread of axial blind hole hypomere.By this mode of structure, bending deformation under the last thin slice that is cut into by radial groove on the nut body, make nut be unable to stir any more, nut is fastened on a certain position of bolt, prevented the loosening of nut, ensure the normal operation and the normal operation of machinery or machine, avoided the machinery that brings because of nut loosening or the instability of machinery operation, increased Safety performance.

As improvement, the horizontal position of described radial groove is arranged on the horizontal plane at sixth to five/place on the top of nut thickness.This position of radial groove is provided with, the last thin slice of the nut body that is cut by radial groove has certain malleable, make screw will go up the thin slice press-bending and be pressed on the following thick seat sheet of nut body rightly, cut thinly excessively if will go up thin slice, when pressing down it, screw ruptures easily, if will go up thin slice cuts blocked uply, the fastening force of screw can not bend it, does not reach the effect of fastening location.

Description of drawings:

Fig. 1 looks schematic representation for the master of the utility model setscrew nut;

Fig. 2 is the schematic top plan view of the utility model setscrew nut.

Shown in the figure: 1, nut body, 2, screwed hole of centre, 3, axial blind hole, 4, radial groove, 5, go up thin slice, 6, thick seat sheet down.

Embodiment:

Below in conjunction with the drawings and specific embodiments the utility model setscrew nut is described further:

Setscrew nut, comprise nut body 1 and screwed hole of centre 2, in the sidewall of nut body 1 one sides, be provided with an axial blind hole 3, see Fig. 1 and Fig. 2, the opening end of axial blind hole 3 is arranged on the upper-end surface of nut body 1, the hypomere of axial blind hole 3 is provided with screw thread, in nut body 1, also be provided with a radial groove 4, see Fig. 1, the opening of radial groove 4 is arranged on the outer side wall of the nut body 1 that is equipped with axial blind hole one side, and radial groove 4 also cuts off axial blind hole 3, sees Fig. 1, the degree of depth of radial groove 4 is seen Fig. 1 greater than the nut radius.The horizontal position of radial groove is arranged on the horizontal plane at sixth to five/place on the top of nut thickness.Present embodiment is arranged on the horizontal plane at 1/5th places.See Fig. 1.

During use, when nut 1 need be located in a certain position of bolt, be inserted in the radial blind holes 3 on the nut body 1 with screw, the last thin slice on the nut body 15 is bent and be pressed on the following thick seat sheet 6 of nut by screw, screw is fastened on the screw thread of axial blind hole 3 hypomeres.By this mode of structure, the last thin slice that is cut into by radial groove 5 on the nut body bends and is out of shape, make nut 1 be unable to stir any more, nut 1 is fastened on a certain position of bolt, prevented the loosening of nut, ensure the normal operation and the normal operation of machinery or machine, avoided the machinery that brings because of nut loosening or the instability of machinery operation, increased Safety performance.

Claims
