Abstract
A hexagon-head high-strength locking bolt is composed of a tip, an anti-loose loop belt, a screw, and the like. The tip of the bolt is of a hexagonal structure, and a concave round surface is arranged inside the top portion of the tip. The anti-loose loop belt is arranged at the position where the tip is connected with the screw, and the position where the inner edge of the anti-loose loop belt is in contact with the screw is designed to be of an R-corner structure. A section of screw neck is arranged on the upper portion of the screw, wherein screw teeth are arranged on the screw neck. Round screw teeth are arranged on the lower portion of the screw, and the round screw teeth are arranged at the same angle. The hexagon-head high-strength locking bolt is high in connecting strength, good in anti-loose effect, high in fastening strength, beneficial for connection among parts, and compact in structure.
Description
Technical field:
The utility model relates to a kind of screw, is specifically related to a kind of hexagonal head height lock bolt.
Background technique:
It is very widely that hex head bolt uses at machinery industry, and hex head bolt is when screwing or dismantle, and the Point of Strength of spanner is on six planes of termination.But it is exactly that easily appearance is loose that a fatal shortcoming is arranged in long-term using process, cause damage will for machinery itself, also may cause thoroughly scrapping of equipment component when serious, cause larger economic loss, and have serious potential safety hazard, but also waste time and energy.
The model utility content:
For the technical deficiency of existing the said goods, the purpose of this utility model is to provide a kind of hexagonal head height lock bolt, and it is comprised of termination, locking endless belt, screw rod etc.
The technological scheme that its technical problem that solves the utility model adopts is: the termination of bolt is hexagonal formula structure, is provided with recessed disc in the top, termination; Termination and screw rod joint are provided with locking endless belt, and locking endless belt inside edge and screw rod contacting point are designed to the R corner structure; The screw rod epimere is provided with a joint spiral shell neck, and thread is not set on the spiral shell neck, and the screw rod hypomere arranges circular thread, and each circular thread is the arrangement with angle.
The beneficial effects of the utility model are: join strength is high, anti-send effectively, and fastening strength is larger, is connected compact structure between feature.
