A New Type of Fiberglass Ball Nut

Abstract

The invention discloses a novel spherical glass fiber reinforced plastic nut. The nut comprises a nut body and an arc-shaped gasket arranged below the nut body; one end of the nut body is set to be a bulging spherical surface, and the other end is set to be cylindrical; the arc-shaped gasket is arranged at the end of the spherical surface of the nut body; an arc-shaped concave part is arranged in the middle of the arc-shaped gasket; the shape of the arc-shaped concave part is matched with the spherical surface of the nut body; a circle of balls are arranged at the arc-shaped concave part of the arc-shaped gasket and are mounted on a circular base; and the circular base is mounted at the arc-shaped concave part. With the nut, the arc-shaped gasket is arranged below the nut body, and the balls are arranged on the arc-shaped gasket, so that sliding friction of the nut body during mounting and fastening is changed into rolling friction, the nut is convenient to mount, and the fastening force is increased.

Description

technical field [0001] The invention relates to a novel fiberglass spherical nut. Background technique [0002] The anchor rod is a support structure. During the installation process of the anchor rod for reinforcement and support, a pallet nut needs to be installed at the end of the anchor rod. In the prior art, most of the component pallet nuts are integrated structures, which are prone to breakage. Even if the The split-type structure also has structural defects and cannot bear large forces. Moreover, the whole support structure is heavy due to the material, which is not easy to operate, which increases the difficulty of construction. [0003] As a composite material, FRP has become a very active field in research, development and application in developed countries in Europe, America and Japan. In the future, as a high-performance material, FRP will become the first choice for the maintenance, inspection and repair of various roads, bridges and civil building structures...
