A connection assembly is used to connect a first body to a second body. The first body includes a bore that is coaxial with a first axis, and a retainer opening that extends coaxially with a second axis. The second axis is perpendicular to the first axis and offset relative to the first axis. In addition, a portion of the retainer opening intersects the bore. The second body includes an insertion portion that is disposed in the bore, a fluid passage that extends through the insertion portion and communicates with the bore, and an outer surface of the second body has a channel. The connection assembly employs an elastic retaining pin that retains the insertion portion within the bore. The retaining pin is disposed in the retainer opening such that a portion of the retaining pin resides in the channel, and the retaining pin is self-aligning and self-retaining.

A female pipe coupling member includes a coupling body and a sleeve 138 disposed around a cylindrical peripheral wall portion of the coupling body. The sleeve has a locking element receiving hole extending therethrough from an inner peripheral surface to an outer peripheral surface. When the sleeve is in a locking element releasing position where the locking element receiving hole radially aligns with a locking element, the locking element is received in the locking element receiving hole to assume an unlocking position. The locking element receiving hole is configured to block the locking element from passing therethrough radially outward and thus holds the locking element in the unlocking position from outside.

A fueling apparatus 1 including: a fueling pipe 4 accommodated in a housing main body 2 having a fueling mechanism, one end of the fueling pipe 4 being connected to the fueling mechanism; an elbow 5 connected to another end of the fueling pipe 4; a fueling hose 10, one end of which being connected to a fueling nozzle 11 with vapor recovering function, and in which a vapor passage 10c and a fuel oil passage 10d are separately disposed from each other; and a separable joint 9 for communicating the fuel oil passage 10d of the fueling hose 10 and inside of the elbow 5 with each other, and for communicating the vapor passage 10c of the fueling hose 10 and a vapor pipe 4 connected to the vapor recovery mechanism with each other.

Provided is a connection mechanism for connecting a tube through a joint to a housing of a valve. At least one of the housing of the valve and the joint is made of a resin. The housing of the valve includes a connection hole for inserting and connecting the joint, and pin insertion holes which is drilled from an external surface of the housing in a direction orthogonal to an axial direction of the connection hole, and penetrates through the connection hole. An annular groove is formed along a circumferential direction of an outer peripheral surface of the joint. In an insertion state of the joint into the housing, the pin is inserted from the pin insertion holes on the external surface of the housing. The pin passes through the annular groove disposed on the joint and comes into engagement with the joint.

The invention provides a quick-locking union connector. A sealing groove is arranged on the outside peripheral surface of a male inner sleeve to retain an o-ring seal. Close contact of the o-ring seal with the inside peripheral surface of a female outer sleeve leads to a robust sealing effect. The female outer sleeve is provided with a bore slot that penetrates through the inside peripheral surface, in an outside-to-inside manner. A locking unit rotates within the bore slot to quickly lock and unlock the engaged interior male unit and exterior female unit. Locked connection of pipes via obstructing protrusion of the locking unit into an annular locking groove can be readily and quickly executed, facilitating accelerated deployment of pipe networks.

A method for assembling a modular cooling system includes attaching a support manifold to a first rail of an equipment rack, the support manifold defining a coolant supply channel and a coolant return channel; and mounting a first cold plate to the support manifold including engaging a manifold supply connector with a plate supply connector in fluid communication, the manifold supply connector being connected in fluid communication with the coolant supply channel of the support manifold, the plate supply connector being connected in fluid communication with a cooling system disposed within the first cold plate.

A telescopic tube assembly having a fixing structure, including: a first tube having at a receiving end offset toward a predetermined direction to form an inward offset arc portion and an outward arc portion opposite to each other; a second tube having an inserting end, wherein an inner diameter of the first tube is greater than an outer diameter of the second tube; and a fastening structure disposed at the receiving end of the first tube, wherein the inserting end of the second tube is inserted into the first tube through the receiving end; by locking the fastening structure, the second tube is pushed against the inward offset arc portion and fixed with the first tube; by loosening the fastening structure, the second tube is released from the inward offset arc portion and is movable relative to the first tube.

A pipe connecting seat has a sleeve and two positioning members. The positioning members are disposed on the sleeve at a spaced interval. Each one of the two positioning members has a positioning arm and a positioning pin. The positioning arm is openably, positionably, and pivotally disposed on the sleeve, and has at least one reinforcing protrusion for increasing strength of the positioning arm. The positioning pin is disposed on the positioning arm and is located out of the positioning arm for positioning the positioning arm and limiting a pivoting opening range of the positioning arm. When the pipe connecting seat is connected to two pipes, the two positioning members are always located on the sleeve and are not prone to loss. The operating convenience of the pipe connecting seat is increased.

A fluid coupling system for vehicles configured to be attached to the chassis, comprising a male connecting element, a female connecting element and a retaining bolt, the male element comprising at least one axial section configured for insertion into a housing of the female element, both said elements comprising pass-through openings that coincide with respect to a common axial axis, the female element comprising an opening that crosses the housing orthogonally to the axial axis but at a distance from same, the male element comprising at least one grooved neck in at least one of the axial sections to be inserted into the female element, said neck and said opening being configured to receive the bolt in its condition of use, the bolt containing an elastic ring seated in a circumferential groove close to the end thereof.
