Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1 to 3, the present invention provides a technical solution: a waterproof joint comprises a first joint 1 and a second joint 2, wherein a first thread part 3 and a second thread part 4 are respectively arranged outside the first joint 1 and the second joint 2, the first thread part 3 and the second thread part 4 are arranged into reverse threads, the first joint 1 and the second joint 2 are butted together by a thread bush 5, the thread bush 5 is connected with the outer threads of the first thread part 3 and the second thread part 4, a convex block 13 is fixedly connected outside the thread bush 5, the thread bush 5 is convenient to rotate, an elastic rubber bush 6 is bonded at one end of each of the first joint 1 and the second joint 2, the elastic rubber bush 6 is arranged into a conical structure, the diameter of the end part of the elastic rubber bush 6 is smaller than that of a cable, and the elastic rubber bush is favorable for being better sleeved outside the cable;

the equal fixedly connected with U type shell fragment 11 in the inboard that first joint 1 and second connect 2, one side of two sets of U type shell fragments 11 all sets up to the arc structure, and the inside fixedly connected with compression spring 12 of U type shell fragment 11, one side of U type shell fragment 11 is equipped with anti-skidding line, after inserting the cable in first joint 1 and second connect 2, U type shell fragment 11 can extrude the cable, fix the position that first joint 1 and second connect 2, prevent that first joint 1 and second from connecting 2 and moving at will.
