Device for handling and/or processing parts, having first and second subassemblies separably connectable by a connection interface that results from a first contact section of the first subassembly being plugged and/or pressed in a connecting direction onto a second contact section of the second subassembly in a first orientation specified relative to the second contact section. The connection interface includes an electrical interface for transmitting electrical power and/or communication signals between the subassemblies and a fluid interface for transporting fluid between the subassemblies. The first and second contact sections are configured so the connection interface also results if the first contact section is plugged or pressed in the connecting direction onto the second contact section in a further orientation. The further orientation corresponds to the first orientation aside from a rotation of the first contact section by a specified angle about a rotation axis running in the connecting direction.

An end-form fitting includes a tube and an auxiliary component disposed around the tube. One of the tube and the auxiliary component is deformed to cause the auxiliary component to engage the tube in order to militate against relative movement between the tube and the auxiliary component. The auxiliary component includes an array of surface irregularities formed therein and configured to engage an outer circumferential surface of the tube to form a corrugated joint therebetween. The auxiliary component is formed to include a radially outwardly extending orientation structure for establishing a rotational orientation of the end-form fitting when being coupled to a complimentary end-form fitting.

A connector includes one or more spirals securing a fluid conduit to the connector for fluid communication with another hollow object such as another fluid conduit. The spiral(s) press/compress and seal the conduit around an outer circumference of an end of rigid, hollow insert of the connector. Another portion of the connector may include spiral(s) that press/compress and seal a second conduit around a second end of the insert, or may include a hose-coupler that connects to a second conduit. Thus, two fluid conduits may be fluid-sealed to an inner-passageway of the insert, by tightened spiral(s) or by tightened spiral(s) and coupler combination, so the conduits are in fluid communication with each other. The spiral(s) may be retained in, and released from, the tightened condition, by a ratchet-based latching and unlatching system.

A sealing vibrational-counterrotation-proof hose joint capable of solving the poor sealing performance and the poor vibrational-counterrotation-proof performance of the prior hose joints, comprising a joint main body and a screw cap; a connecting section is arranged on the joint main body, and the screw cap is connected to the connecting section; the connecting section is provided with hooking claws; a squeezing section is arranged on the screw cap, and the squeezing section can squeeze the hooking claws, thereby enabling the hooking claws to bend towards the central axis of the joint main body; the screw cap is provided with locking blocks; the side wall of the connecting section is provided with locking grooves and a plurality of spiral guide bars; the spiral guide bars are uniformly distributed in a circumferential direction by taking the central axis of the joint main body as the center.

A locking mechanism for a quick connect coupling having a locking sleeve (100) is disclosed. The locking sleeve is axially displaceable for locking the quick connect coupling in a locked position (110) and for unlocking the quick connect coupling in an unlocked position (120). The locking mechanism comprises a safety ring (200), the safety ring (200) is axially displaceable for engaging the locking sleeve (100) and the safety ring (200) being partly inside or partly outside the locking sleeve (100). The safety ring being positionable in three different axial positions, a first axial position (210) for allowing the locking sleeve (100) to be in the unlocked position (120), a second axial position (220) for allowing the safety ring (200) to rotate, and a third axial position (230) for allowing the locking sleeve(100) to be in the locked position (110). The locking mechanism comprises a spring (300), the spring acting between the locking sleeve (100) and the safety ring (200). The spring (300) comprising a spring force forcing the locking sleeve (100) and the safety ring (200) away from each other. Methods using the locking mechanism are also disclosed.

Disclosed is a connector for connecting one fluid handling device (52) such as a conduit to another fluid handling device (70) such as another conduit in which the faces of fittings (54) attached to glands (50) in the connector are given complementary mating configurations (58, 60, 82) so they can mesh that lack circular symmetry so that the faces do not rotate with respect to one another when the faces are subjected to torque when a connection is being made.

The disclosed invention is a union connection common in connecting pipelines in various industries comprising a threaded female pipe end, a male pipe end insertable into the female pipe end to form a sealed connection, a plurality of shaped ring segments and a threaded collar in which the shaped ring segments are placed in a shaped groove on the male pipe and positioned in the threaded collar. The threaded female pipe end is then threaded onto the threaded collar, the threads each being clocked so as to press the collar against the male pipe using the ring segments and into a sealed connection with the female pipe. A pin inserted through a pin hole in the collar and into a pin recess in the female pipe end holds the parts in place. The pin hole and pin recess are positioned relative to the clocked threads of the collar and female pipe.

A coupling apparatus for a corrugated hose, having a receptacle part for receiving the corrugated hose and a locking part, mounted on the receptacle part, for locking the corrugated hose in the coupling apparatus, wherein the locking part has a resiliently deformable engaging element for interlocking engagement in a corrugation of the corrugated hose, the receptacle part having a receptacle region for receiving the engaging element, wherein the coupling apparatus can be brought by means of a movement of the locking part relative to the receptacle part from an unlocked state, in which the engaging element is arranged outside of the receptacle region, into a locked state, in which the engaging element is arranged within the receptacle region such that the receptacle region blocks a movement of the engaging element in a radial direction of the coupling apparatus, and vice versa.

A coupling includes a male adapter and a female adapter, and may include a nut and a sleeve. In embodiments, the male adapter includes a male adapter inner diameter, and may include threads. The female adapter includes a female adapter outer diameter. The nut or other formation may be configured to engage at least a portion of the male adapter. In embodiments, one or more contact points may be provided between the female diameter outer diameter and the male adapter inner diameter, and the female adapter outer diameter or the male adapter inner diameter may be configured to be out-of-round. The male adapter may include a shoulder and the sleeve may cover the shoulder in connected configuration. Methods for forming a coupling are also disclosed.

Disclosed is a quick-disassembly nipple connector structure, which is mainly composed of a hollow pipe, a pivoting assembly, a screwing member, a plurality of gripping jaws, a sleeve, a handle and a spring. The handle is additionally disposed on the sleeve and the pivoting assembly; when the handle is not pulled, the sleeve is located at a lock position to lock a grease nipple; and when the handle is pulled downwards, the sleeve is located at a release position to release the grease nipple. The quick-disassembly nipple connector structure can be rapidly switched to the lock position or the release position, thus, facilitating operation, shortening the work time, achieving accurate alignment, improving work efficiency, and avoiding damage to internal parts caused by excessive force application by users.
