A syringe attachment/detachment mechanism enables a syringe to be easily attached to and detached from a discharge device without causing twisting of a tube, and enabling the syringe and an adapter to be fixedly held in a desired orientation. In the syringe attachment/detachment mechanism and the device provided with the mechanism, the mechanism being adapted for a discharge device to which a syringe including an attachment part and an upper connection part is attached through screwing, the attachment part includes an inner cylindrical portion having a small-diameter opening, an outer cylindrical portion surrounding the inner cylindrical portion, and a screw portion. The attachment/detachment mechanism includes a support member including a cylindrical insertion portion into which the inner cylindrical portion is inserted, and having a channel formed therein for communication between the small-diameter opening and a nozzle of the discharge device. A rotation member includes a screw portion.

Ventilation systems are disclosed that include a base unit having a mounting platform connecting the base unit to a surface. Such base units have a base collar that extends away from the mounting platform and forms a perimeter of a opening through the base unit. Such ventilation systems include a fan unit that has a fan housing and a fan. The fan housing is configured to receive air through an inlet and expel air through an outlet, and the fan is capable of moving air from the inlet to the outlet. Such ventilation systems also include a quick connect interface that has a base feature and a fan housing feature. The base feature is integrated into the base unit, and the fan housing feature integrated into the fan unit; both are capable of detachably connecting together to secure the fan unit to the base unit.

A coupler, adapted for being assembled and connected with a water sprayer, includes a sleeve and a coupling member adapted for being assembled and connected with the water sprayer. The coupling member and the sleeve are sleeved with each other and respectively have a first corresponding end and a second corresponding end which correspond to each other. The first corresponding end and the second corresponding end are adapted to be engaged with each other, so that the sleeve and the coupling member are capable of being mutually locked and into a non-rotatable state through the engagement and rotation meshing operation. The sleeve can be disengaged with the coupling member through axially moving the sleeve so that the sleeve is allowed to be axially rotatable.

A coupling device is provided for mounting on a bib of a faucet to releasably secure a hose or some other component to the bib. The coupling device includes an engagement surface, a gasket ring, a clamp assembly and a locking assembly. The coupling device is configured so that the clamp assembly can be actuated to mount the coupling device on the bib. The gasket ring is configured to be compressed between the engagement surface and the bib to enable liquid to flow from the bib into the coupling device and out of it into the hose or other component without leakage. The locking assembly is configured to lock the coupling device on the bib, but is releasable when desired to dismount the coupling device from the bib.

A heat pipe, a heat pipe assembly and a method for assembling the heat pipe assembly. The heat pipe includes a main body part and an insertion part. The insertion part is connected to the main body part. The main body part and the insertion part together form a single hollow pipe. The insertion part has an outer surface and at least one recessed part formed on the outer surface.

A testing or filling adapter (1) for a container to be filled with fluid, composed of a body (10), an attachment module (3), and a coupling system (30) having a coupled position, in which a sealed connection is established between the body and the attachment module, and an uncoupled position. The body includes a feed module (2) that comprises a plurality of conduits that include at least one fluid conduit (221) and is equipped with a safety valve (5) that can be moved between an open configuration and a closed configuration and is connected to an element mirror (51) having a first configuration in which the safety valve is in the open configuration and a second configuration in which the safety valve is in the closed configuration. The filling adapter further comprises a safety device (6) that cooperates with the coupling system, with it being possible to move said safety device between a locked position, in which the safety device locks the coupling system in the coupled position, and an unlocked position, in which the safety device enables the coupling system to be moved into the uncoupled position. The safety device cooperates with the mirror element so as to enable the mirror element to be in its first configuration when the safety device is in the locked position, and to force the mirror element to be in its second configuration when the safety device is moved from its locked position to its unlocked position.

The invention relates to a fluid coupling (1) with tolerance compensation for the flexible connection of two media-conducting elements. The invention was based on the object of improving a fluid coupling (1) of the described type in such a manner that the use of complicated latching systems for transport can be omitted. This object is achieved in that the fluid coupling (1) has at least one transport securing device (8, 12), by means of which a separation of the components (2, 3) of the fluid coupling (1) from one another prior to installation can be prevented.
