Problems solved by technology
[0005] The purpose of the present invention is to provide an explosion-proof cable sealing joint to solve the problem that the existing explosion-proof cable sealing joint in the above-mentioned background technology has an excessive clamping force in the process of clamping the cable for a long time, which may cause the cable surface to be locally overstressed. The surface is damaged and the clamping force is too small, which will easily cause the cable to shake

The invention relates to the technical field of cable installation parts, and discloses an explosion-proof cable sealing joint in the technical field of cable installation parts. , a fixed cylinder and a No. 1 cone. The outer wall of the fixed cylinder is evenly provided with external threads. The inner cavity of the fixed cylinder is fixedly installed with a No. 1 cone. The bottom of the No. 1 cone is set as an inner cone surface. No. 2 conical cylinder, long cylinder bearing, connecting cylinder and rotating cylinder, the outer wall of the rotating cylinder is evenly provided with anti-skid teeth, the upper end of the inner wall of the rotating cylinder is provided with internal threads, the rotating cylinder is screwed with the fixed cylinder, and the inner wall of the middle of the rotating cylinder is provided with In the inner groove, the invention not only ensures the installation requirements of the sealing installation during the cable sealing installation process, but also realizes the stable clamping by increasing the torsion force of the screw, and prevents the cable surface from being easily affected by excessive force. Excessive force causes the problem of surface damage.
Description
technical field [0001] The invention relates to the technical field of cable mounting parts, in particular to an explosion-proof cable sealing joint. Background technique [0002] When the cabinet body is installed with external cables, it is often necessary to open cabinet installation holes on the cabinet wall, while the explosion-proof cable gland is a fixture installed in the cabinet installation holes and for the external cables to pass through. It is used to strengthen the connection between the external cables and the cabinet. The sealing performance between the mounting holes of the body so as to meet the explosion-proof requirements. [0003] Excessive clamping force of the existing explosion-proof cable sealing joint in the process of clamping the cable for a long time may easily cause the surface of the cable to be partially stressed and cause surface damage, and the clamping force is too small to easily cause the cable to shake. [0004] Based on this, the prese...
