Problems solved by technology

The defect of this structure is: 1, the groove width between the nut side walls is greater than the diameter of the bolt connected by the U-shaped nut. The larger the bending moment, the worse the force condition of the pin shaft and it is easy to be damaged; 2. The increase in the diameter of the pin shaft leads to a corresponding increase in the width of the nut side wall, so that the volume and weight of the U-shaped nut also increase accordingly, which is difficult for installation and construction. Inconvenience

Embodiment Construction

[0013] The present invention will be further explained below in conjunction with the accompanying drawings.

[0014] like figure 1 As shown, it is a U-shaped nut in the prior art, which includes a nut bottom with an internal thread through hole and two symmetrical nut side walls. The nut side wall is provided with a shaft pin hole, and the nut side wall is perpendicular to the nut bottom. , is a straight groove, and the side wall of the nut is a straight up and down rectangular structure. The defect of this structure is: 1, the groove width between the nut side walls is greater than the diameter of the bolt connected by the U-shaped nut. The larger the bending moment, the worse the force condition of the pin shaft and it is easy to be damaged; 2. The increase in the diameter of the pin shaft leads to a corresponding increase in the width of the nut side wall, so that the volume and weight of the U-shaped nut also increase accordingly, which is difficult for installation and c...

Abstract

The invention discloses a U-shape nut, comprising a nut bottom part with an inner thread through hole, and two symmetric nut lateral walls. Pin axle holes are arranged on the nut lateral walls. Each nut lateral wall is composed of an inclined groove (1) which inclines towards the inner side of the U-shape nut, and straight grooves (2) with the pin axle holes. The groove width between the straight grooves (2) is particularly reduced as to the maximal width of the inclined groove (1) by the U-shaped nut of the technical scheme so that the bending moment supported by a pin shaft (3) is reduced, the loading condition of the pin shaft (3) is obviously improved, the service life of the pin shaft (3) is improved and the security and the quality of the device are guaranteed.

Description

technical field [0001] The invention relates to a pipe connector, in particular to a U-shaped nut. Background technique [0002] At present, the existing U-shaped nuts include a nut bottom with an internal thread through hole and two symmetrical nut side walls. The nut side walls are provided with shaft pin holes. The nut side walls are perpendicular to the nut bottom and are straight grooves. , and the side wall of the nut is a straight up and down rectangular structure. The defect of this structure is: 1, the groove width between the nut side walls is greater than the diameter of the bolt connected by the U-shaped nut. The larger the bending moment, the worse the force condition of the pin shaft and it is easy to be damaged; 2. The increase in the diameter of the pin shaft leads to a corresponding increase in the width of the nut side wall, so that the volume and weight of the U-shaped nut also increase accordingly, which is difficult for installation and construction.
