Nut box

Abstract

The invention aims at providing a nut box which is used for fixing nuts in a narrow space and can bear larger torque force. The nut box has the box-shaped structure with an opening at the bottom surface, the top surface thereof is provided with a through hole for the passing of a bolt, the side edge of the nut box is matched with the shape of the side edge of the nut to be fixed, and the bottom of the side surface of the nut box is provided with a flanging. When in use, the nut to be fixed is arranged inside the nut box firstly, then the nut box is placed on a component to be fixed and the position of the nut box is regulated so as to lead the through hole thereof to be aligned to the bolt hole, in which the bolt is to be installed, and finally the flanging at the bottom of the side surface of the nut box is welded and fixed on the component to be fixed. The nut box can bear larger torque force and can fasten and loosen the bolt from a single side, thus being available for the occasions with narrow operation space; and the nut box is characterized by simple structure, low cost, safe and reliable connection and high assembly efficiency.

Description

technical field [0001] The present invention relates to a component for securing a nut when installing a bolt. Background technique [0002] When installing bolts, you first need to fix the nuts with a wrench on one side, and then use a wrench to rotate and tighten the bolts on the other side. The operation space for tools such as wrenches must be reserved on both sides of the bolts and nuts. Projection welding nuts can be used in narrow operating spaces. First weld the projection welding nuts on the parts to be fixed, and then tighten the bolts. However, due to the limited welding strength of the projection welding nuts, they are only suitable for occasions with small torque. If it is forcibly used in a place with a large torque force, it will easily cause hidden dangers such as unstable fixation and loose bolts. Contents of the invention [0003] The object of the present invention is to propose a nut box for fixing nuts in a narrow space, which can bear a large torque ...
