Abstract
The utility model discloses an automobile engine cylinder block shockproof fastener which comprises a bolt rod body, the back face of the bolt rod body is fixedly connected with a bolt head, the outer surface of the bolt rod body is provided with external threads, the outer surface of the bolt rod body is in threaded connection with a back locking nut, and the bolt head is fixedly connected with the back locking nut. And expansion holes are formed in the rear end of the bolt rod body and the back face of the bolt head correspondingly, an expansion rod is arranged in the two expansion holes jointly, and the front face of the bolt rod body is fixedly connected with an anti-vibration pad. According to the device, through mutual cooperation of the bolt rod body and the external threads, the bolt can be conveniently fixed, the bolt can provide the needed tensile force, the normal use effect is achieved, through mutual cooperation of the expansion hole and the expansion rod, connection and reinforcement can be conducted after the bolt is connected and fixed in a threaded mode, the bolt rod body is expanded, and the bolt is convenient to use. And by arranging the back locking nut, back locking can be conducted on the bolt rod body after the bolt is in threaded connection.
