Embodiment 1

[0034] A back nut such as figure 1 and figure 2 As shown, it includes a nut body 1, the end surface of one end of the nut body 1 is a slope 2, and the angle between the slope 2 and the plane where the end surface of the other end of the nut body 1 is located is A, and A is greater than 0° and less than 90°.

[0035] When using the anti-retraction nut with the above structure, the worker can direct the slope 2 of the nut body 1 toward the workpiece 4 and connect and fix it with the screw or bolt, so that the lowest point of the slope 2 contacts the workpiece 4. At this time, The staff can continue to tighten the nut body 1, so that the inclined surface 2 of the nut body 1 fits the workpiece 4, and the internal thread on the nut body 1 squeezes the external thread on the screw or the bolt, so that the external thread on the screw or the bolt produces elasticity deformation, so as to increase the bite force on the nut body 1 and the screw rod or bolt, and then achieve the effec...

Embodiment 2

[0039] Such as figure 1 and image 3 As shown, as another specific embodiment of a stop nut of the present invention, the stop nut also includes a fastening nut 3 used in conjunction with the nut body 1, through the cooperation of the fastening nut 3 and the nut body 1, The anti-retraction nut also has a good anti-retraction effect, and can also protect the workpiece 4 well, so that the workpiece 4 will not be squeezed by the nut body 1 and cause the workpiece 4 to be damaged.

[0040] During specific use, the staff can install the above-mentioned nut body 1 on the screw rod or bolt on the workpiece 4, make the inclined surface 2 of the nut body 1 away from the side of the workpiece 4, and then install the fastening nut 3 on the screw rod correspondingly. Or on the bolt, make the fastening nut 3 contact with the highest point of the slope 2 of the nut body 1. At this time, the staff can continue to twist the fastening nut 3 so that the lower end surface of the fastening nut 3...

Embodiment 3

[0046] Such as Figure 4 As shown, the present invention provides a back-stop washer, which includes a washer body 5 and a fastening nut 3. The end face at one end of the washer body 5 is an inclined plane 2, and the plane between the inclined plane 2 and the end face at the other end of the washer body 5 is located. The angle is B, and B is greater than 0° and less than 90°; the fastening nut 3 is located on one side of the bevel 2 of the washer body 5 .

[0047] With the anti-retraction washer of the above structure, the end surface of the fastening nut 3 is attached to the inclined surface 2 by turning the fastening nut 3. At this time, the internal thread of the fastening nut 3 squeezes the outer surface of the screw or bolt The thread makes the internal thread of the fastening nut 3 and the external thread on the screw rod or the bolt produce elastic deformation, thereby increasing the occlusal force between the internal thread in the fastening nut 3 and the external thre...

Abstract

The invention belongs to the technical field of fasteners, and particularly relates to a check nut, a check gasket and a check bolt. A slope is arranged on a nut body or a gasket body, by screwing thenut body or a fastening nut, the nut body fits the surface of a workpiece or the end face of the fastening nut fits the slope, the elastic deformation happens to an internal thread of the nut body orthe fastening nut and an external thread of a screw or a bolt, and therefore the meshing force between the internal thread of the nut body or the fastening nut and the external thread of the screw orthe bolt is increased, and the check effect is achieved. A slope is arranged on the head portion of the check bolt, when the check bolt is installed on the workpiece, the slope fits the surface of the workpiece or the gasket, the elastic deformation happens to the external thread of the screw in the check bolt and an internal thread of the workpiece, and therefore the meshing force between the external thread of the screw and the internal thread of the workpiece is increased, and the check effect is achieved.

Description

technical field [0001] The invention belongs to the technical field of fasteners, and in particular relates to a backstop nut, a backstop washer and a backstop bolt. Background technique [0002] With the development of the economy, fasteners are becoming more and more important in the industry, and nuts for anti-loosening and anti-retraction are more and more widely used in machinery, so it is very important for the research and development of anti-loosening nut products. [0003] In the prior art, there are many fasteners with better anti-retraction effects. For example, two nuts are respectively provided with a convex part and a groove, wherein the groove is concentrically arranged on the nut, and the convex part is non-concentrically arranged on the other On one nut, by twisting the nut with the convex part, the convex part is squeezed into the groove, so that elastic deformation occurs between the two nuts, and at the same time, the screw rod is forced to produce corres...
