Abstract
The invention discloses a bolt with a convex round head. The bolt with the convex round head comprises a main body bolt and a security end bolt, wherein a main bolt head is arranged at one end of the main body bolt; a threaded cavity is formed in the other end of the main body bolt; threads are formed in the excircle surface of one end of the security end bolt; the end of the security end bolt extends in the threaded cavity and then is in threaded connection with the main body bolt; a security end bolt head is arranged at the other end of the security end bolt; and the outer end surface of the main bolt head and the outer end surface of the security end bolt head are spherical surfaces. The main body bolt is connected with the security end bolt, and two ends of the main body bolt and two ends of the security end bolt are tensioned, so that a security fixing effect is achieved. In addition, the bolt with the convex round head is simple in structure and easy to manufacture.
Description
Technical field
