Description

Clinch nut assembly

Technical Field

The utility model relates to a nut field, more specifically say, relate to strike nut component.

Background

At present, the nut usually needs to be screwed or loosened in a rotating mode, a large torque is needed when the nut is used for pressurizing or loosening the joint, construction is time-consuming and labor-consuming, and the nut is easy to loosen by itself under the influence of vibration. The nut is difficult to unscrew again when it rusts and usually requires breaking. The utility model discloses strike the mode fastening that nut component adopted to strike and connect, easily obtain bigger fastening pressure, prevent that the nut from receiving vibrations to influence not hard up, rusty nut still easily loosens, and the efficiency of construction increases substantially moreover.

Disclosure of Invention

In order to overcome the deficiency of the background art, the utility model discloses strike nut component has following advantage: easily obtain bigger fastening pressure, prevent that the nut from receiving vibrations influence not hard up, rusty nut still easily loosens, and the efficiency of construction increases substantially.

The technical scheme of the utility model, include: the upper nut, the middle knocking gasket and the lower inclined plane gasket can be screwed or loosened on the bolt in a rotating mode; the contact surface of the middle knocking gasket and the lower inclined surface gasket is an inclined surface, namely a wedge shape, and a strip-shaped hole is formed in the middle knocking gasket; the contact surface of the lower inclined plane gasket and the middle striking-up gasket is an inclined plane, and the inclination of the inclined plane is the same as that of the inclined plane of the middle striking-up gasket; the clinch nut assembly may be clinched or loosened by striking the intermediate clinch pad. When the nut is screwed, the upper nut is rotated and slightly screwed, and then the middle screwing gasket is knocked to fasten the screwing nut component; when the nut is loosened, the middle knocking gasket is knocked reversely to enable the knocking nut component to be loosened, and after the knocking nut component is loosened, the knocking nut component can be directly removed or the upper nut can be loosened in a rotating mode by small force.

The inclined plane of the middle knocking gasket and the inclined plane of the lower part inclined plane gasket are provided with concave-convex grooves for preventing the knocking nut assembly from loosening.

After the middle knocking gasket is knocked down, the end part of the middle knocking gasket is knocked down, so that the end part of the middle knocking gasket is bent, and the knocking nut assembly can be prevented from loosening.

One end of the strip-shaped hole of the middle knocking gasket is provided with a gap, namely the hole is in an open U shape.

The positions of the middle knocking gasket and the lower inclined plane gasket can be exchanged.

The middle knocking gasket and the lower inclined plane gasket are added to the existing nut, so that the existing nut has the function of knocking or loosening.

The middle gasket and the lower inclined plane gasket are tightly knocked in the middle of the nut of the scaffold fastener, so that the scaffold can be disassembled and assembled only by knocking, and the repeated work of screwing and loosening the nut is avoided.

Through the technical scheme, the utility model discloses technical scheme's beneficial effect is: easily obtain bigger fastening pressure, prevent that the nut from receiving vibrations influence not hard up, rusty nut still easily loosens, and the efficiency of construction increases substantially.

Detailed Description

Embodiment 1, as shown in fig. 1 the present invention provides a clinch nut assembly comprising: the upper part nut 1, the middle knocking gasket 2 and the lower inclined plane gasket 3 are arranged on the bolt, and the upper part nut 1 can be screwed or loosened in a rotating way; the contact surface of the middle knocking gasket 2 and the lower inclined plane gasket 3 is an inclined plane, namely a wedge shape, and a strip-shaped hole is formed in the middle knocking gasket and is semicircular at two ends; the contact surface of the lower inclined plane gasket 3 and the middle striking gasket 2 is an inclined plane, and the inclination of the inclined plane is the same as that of the intermediate striking gasket 2; the clinch nut assembly may be clinched or loosened by striking the intermediate clinch pad 2. When the nut is screwed, the upper nut 1 is rotated and slightly screwed, and then the middle screwing gasket 2 is knocked to fasten the screwing nut component; when the nut is loosened, the middle knocking gasket 2 is knocked reversely to loosen the knocking nut component, and the knocking nut component can be directly removed after loosening or the upper nut 1 can be rotated and loosened by small force.

Embodiment 2, as shown in fig. 2 and 3 the utility model discloses strike tight nut component, there is the tongue and groove on the inclined plane of striking tight gasket 2 in the middle and the inclined plane of lower part inclined plane gasket 3 for it is not hard up to prevent to strike tight nut component.

Embodiment 3, as shown in fig. 4 the utility model discloses strike nut component strikes in the middle of striking after tightly striking gasket 2, strikes in the middle of striking the tip of tightly striking gasket 2 for 2 tip bending of gasket are struck in the middle of, can prevent to strike nut component not hard up.
