Embodiment Construction

[0013] The interlocking fastener with two bolts and single caps in the figure includes a main bolt 1 and a lock nut 2. It is characterized in that: an inner screw hole 4 is provided in the center of the end face of the screw rod 3 of the main bolt, and the lock nut 2 is formed by The thread is screwed on the screw rod 3 of the main bolt 1, and one surface of the lock nut 2 is provided with a raised thin-walled circular lock ring 5, and the center of circle of the thin-walled circular lock ring is connected with the center of the lock nut. point concentric, there is a pair of bolts 7, consisting of a screw rod 8 and a bolt head 9, the external thread on the screw rod 8 of the auxiliary bolt 7 cooperates with the internal thread of the screw hole 4 on the end surface of the screw rod 3 of the main bolt 1. An annular groove 10 is opened on the inner side of the bolt head 9 of 7 , and the annular groove 10 corresponds to the thin-walled circular lock ring 5 of the lock nut 2 . The...

Abstract

The invention designs a two-bolt single-cap interlocking fastener which comprises a main bolt and a lock head nut, an inner countersunk bolt hole is formed in the center of the end face of a bolt rod of the main bolt, the lock head nut is screwed on the bolt rod of the main bolt through a thread, a protruding thin-wall circular locking ring is arranged on one face of the lock head nut, and the center of circle of the thin-wall circular locking ring is concentric with the center point of the lock head nut; and an auxiliary bolt is arranged and composed of a bolt rod and a bolt head, an external thread on the bolt rod of the auxiliary bolt is matched with an internal thread of the inner countersunk bolt hole in the end face of the bolt rod of the main bolt, a ring groove is formed in the inner side face of the bolt head of the auxiliary bolt, and the ring groove corresponds to the thin-wall circular locking ring of the lock head nut. The two-bolt single-cap interlocking fastener has the advantages that the number of the parts is only three, the structure is simple, the machining process is simple, production is easy, mutual locking and fastening are conducted at three different point positions in the threaded connection mode and the hoop connection mode, therefore the performance of durable, stable and firm connection is achieved, and the connecting structure is of a non-open closed structure.

Description

technical field [0001] The invention relates to a fastener, in particular to a fastener with two bolts and one cap interlocking. Background technique [0002] Fastener is a kind of mechanical parts that are widely used for connection. From the deep sea to space, it has its small figure on various man-made objects. It plays an important role in the connection of various object structures created by people. play an indispensable role. In order to firmly connect various components in various static buildings and dynamic mechanical equipment, people continue to improve it so that it has a more permanent and firm fastening performance in the connection. . Therefore, in the connection between the bolt and the nut of one of the fasteners, there are such things as spring washers, double nuts, forward and reverse threaded bolts and nuts, toothed inclined-plane washers, and blueprints and principles are also available. Eccentric nuts, which are difficult to replicate and never loos...
