20100084855 | ECONOMY LIQUIDTIGHT FITTING - A fitting for a liquidtight conduit that includes a compression ring, a ground cone and a locknut. The compression ring has a first end that is adapted to receive a liquidtight conduit and a second end that has a perimetrical lip that extends radially from the exterior surface and a collar that extends from the second end. The locknut is ring-shaped and has an aperture in the middle. The ground cone has a flanged end and a plain end. The locknut passes over the plain end and is attached to the back side of the flanged end. When the fitting is installed, the plain end of the ground cone passes through an aperture in a wall and the second end of the compression ring. A plurality of threads on the exterior surface of the ground cone engages the interior surface of the liquidtight conduit in the compression ring and, when the ground cone is rotated, the threads move the conduit towards wall. | 04-08-2010 |
20140265305 | CONDUIT COUPLING SYSTEM AND METHOD - A conduit coupling construction including a coupling body threadably mounting a pair of lock nuts on its ends. Conduit ends are passed through the lock nuts and into the coupling body. Each lock nut receives a respective lock ring adapted for compression onto a respective conduit. The lock ring transforms an axial force on the conduit to a shear force to enhance gripping for pull-out resistance. The central body portion is transparent and allows an end of a conduit to pass completely through the body for more convenient installation onto two separated pieces of conduit, thereby joining them. This construction allows the coupler to be slipped over a first conduit section, aligned with a second conduit section, and the two sections joined without the need to bend either conduit. | 09-18-2014 |
20140312610 | PIPE JOINT STRUCTURE - A pipe joint structure includes a connection head, an internal loop and a lock nut. One end of the connection head is disposed with a connection nut adapted to be in connection with other outside device, and another end thereof is disposed with a thread portion and an engagement portion adapted to insert in the tube, allowing the connection head to be coupled to the pipe. The internal loop and the lock nut are respectively engaged with the outer part of the pipe, where the internal loop can be fixed on the outer parts of the pipe and an insertion end of the engagement portion of the connection head, and the lock nut can be engaged with the thread portion of the connection head and covers the outer part of the internal loop fixedly as well. The locking can be carried out by using any tool (e.g. wrench) through the lock nut. Therefore, the lock nut tightly compresses the internal loop, and then the internal loop correspondingly and tightly compresses the thread portion of the connection head and the pipe at the position that they are coupled to each other, allowing the tight coupling of the connection head to the pipe. | 10-23-2014 |

20150345673 | STRUTS AND METHODS UTILIZING A LOCKING COLLAR NUT - Composite tube assemblies comprising a composite tube comprising a variable diameter portion comprising a first frustoconical portion and a second frustoconical portion, wherein a diameter of the composite tube at an interface between the first frustoconical portion and the second frustoconical portion is a maximum diameter value with respect to the first frustoconical portion and is a maximum diameter value with respect to the second frustoconical portion, a locking wedge disposed at least partially around a circumference of the first frustoconical portion, a locking collar nut disposed at least partially around a circumference of the locking wedge; and an end fitting disposed at least partially around a circumference of the second frustoconical portion, wherein the end fitting is coupled to the locking collar nut are disclosed. Methods of manufacture are also disclosed. | 12-03-2015 |
20150362108 | MOVEMENT-CONSTRAINING ASSEMBLY FOR FLUID-CONVEYING SYSTEM - A movement-constraining assembly for a fluid-conveying system comprises a tubular body adapted to be secured to a component coupling end of a component of the fluid-conveying system. A fluid-conveying tube has a tube coupling end adapted to be connected to the component of the fluid-conveying system and defining an inner passage for fluid to pass therethrough to or from the component, the tube having an interface at the tube coupling end. A blocking nut has an inner surface complementary to at least a surface of the interface of the tube to block rotation between the tube and the blocking nut, the blocking nut further comprising an outer surface complementary to a surface of the tubular body to block rotation between the blocking nut and the component, whereby the blocking nut blocks a rotation between the fluid-conveying tube and the component coupling end. | 12-17-2015 |
20160047502 | Quick Connection Arrangements with Locking Mechanisms - Quick connect arrangements for securing together first and second tubular members. A securing sleeve helps secure the connection together and include locking arrangements which ensure that the securing sleeve cannot be inadvertently unthreaded. | 02-18-2016 |
