摘要： A sprinkler with a push-in connection includes a sprinkler frame, an operating element, and a sealing cap. The sprinkler also includes one or more sealing gaskets and a retainer. Each such sealing gasket is located at least partially within a groove in the sprinkler frame. The retainer is also at least partially located within a groove in the sprinkler frame. The retainer connects to an internal bore of an outlet of a fluid supply conduit when the sprinkler is installed in the outlet. The one or more gaskets seal against the internal bore of the outlet when the sprinkler is installed in the outlet. The retainer is a spring mechanism so that the diameter of the retainer is reduced when the sprinkler is inserted into the internal bore of the outlet, and the retainer maintains pressure against the outlet internal bore.

摘要： A gardening fluid connection device contains a body including multiple retainers, a resilient element, and a fitting sleeve including multiple spaced engagement teeth. The resilient element abuts against the body and the fitting sleeve. The body includes a stop rib, and the multiple spaced engagement teeth are pushed by the resilient element to abut against the stop rib. The body includes at least one retaining element, each retaining element is located on a first side of each spaced engagement tooth, and a width of each spaced engagement tooth is equal to a rotation distance of the fitting sleeve, hence the fitting sleeve is rotated reciprocatingly to open or close of the gardening fluid coupling device by using the stop rib, each retaining element, each spaced engagement tooth and the resilient element, and each retaining element is stopped when moving to a second side of each spaced engagement tooth.

摘要： Proposed herein is a coupler cap and a quick coupler having the same, which can improve coupling power when the cap is coupled with the male coupler and maintain the coupled state with no gap so as to protect the coupler more perfectly. The coupler cap includes: a cap body having one side, which is opened and has a receiving hole so that a male coupler is inserted into the cap body in an axial direction, and the other side, which is closed; a handle connected to the cap body to be rotatable in a radial direction as an axial line; and a stopper moved rectilinearly in the radial direction of the cap body by rotation of the handle.

摘要： A connector can include multiple circumferentially distributed engagement structures which clamp two hubs together, and a biasing device which biases the engagement structures toward an open configuration thereof, in which the hubs are separable from each other. Another connector can include multiple circumferentially distributed engagement structures, each having a recess which receives hubs therein, and a sleeve which encircles the engagement structures and prevents the engagement structures from displacing radially outward from an open configuration thereof, in which the hubs are separable from each other. A method of making a connection to a wellhead can include applying pressure to a connector, thereby allowing multiple circumferentially distributed engagement structures to displace outward to an open configuration thereof, and displacing one hub of the connector into contact with another hub secured to the wellhead, the engagement structures axially aligning the hubs during the displacing.

摘要： A connector for a component of a medical breathing circuit. The connector comprises an inner body and an outer body. The outer body is configured to be slidable along the inner body between each of an inoperative orientation and an operative orientation with respect to the inner body. The outer body and the inner body are configured to be in engagement or in an operative association with each other when the outer body is provided in the operative orientation. The outer body and the inner body are disengaged from each other or in an inoperative association with each other when the outer body is provided in the inoperative orientation. At least one or each of a surface of the inner body or a surface of the outer body comprises of a surface relief feature(s) providing for a resistance to the outer body being moved from the inoperative orientation to the operative orientation.

摘要： The invention relates to a female quick coupling element (200) comprising a hollow female body (204) defining a central axis (X200), locking members (208), each locking member being radially movable inside a corresponding radial opening (204.1) of the female body between a locked position and an unlocked position, at least one memory element (206), movable along a movement axis (D206) between a distal position, in which it opposes the movement of a locking member from the unlocked position to the locked position, and a proximal position, and a locking ring (218), which is axially movable between a forward position, in which it keeps the locking members in the locked position, and a withdrawn position. Each memory element (206) is received in a housing defined in the thickness of the body. Each memory element (206) is, in the distal position, closer to the central axis (X200) than the locking members (208) are in the unlocked position, and the movement axis (D206) of each memory element is inclined relative to the central axis (X200) of the female body.

摘要： A fitting connectable to an end portion of a pipe generally includes a tubular insert member configured to be received at least partly within the end portion of the pipe, and a retention member coupled to the insert member and configured to be received at least partly within the end portion of the pipe. The retention member operates in conjunction with the insert member to engage the end portion of the pipe and impart an increased force against an inner wall of the pipe in response to forces tending to separate the fitting from the end portion of the pipe. The insert member includes a plurality of reinforcement ribs formed on its inner surface which provide support to the insert member and help prevent damage thereto from transverse bending forces applied during installation.

摘要： The specification discloses a marine fluid connection system including a fitting and a connector. The fitting is cylindrical and includes a radially extending flange. The connector includes a cylindrical body, a plurality of levers on the body, and a locking ring on the body. The levers are movable between a latched position, in which the levers are closed on the flange to lock the connector on the fitting, and an unlatched position, in which the levers are open so that the connector may be removed from the fitting. The locking ring is axially movable with respect to the body to move the latches between their latched and unlatched positions.

摘要： A coupling includes a housing having a wall defining an interior space and extending along a central longitudinal axis. A ring is movably mounted with respect to the wall. At least one moveable member has an engagement surface for engaging with an adapter that is positionable within the interior space of the housing. One or more ramps are defined on the ring for (i) moving the engagement surface of the moveable member toward the central longitudinal axis upon moving the ring in one direction in order to engage the coupling to the adapter, and (ii) moving the engagement surface of the moveable member away from the central longitudinal axis upon moving the ring in an opposite direction in order to disengage the coupling from the adapter.

摘要： A diesel fuel cross-drop prevention kit that provides a multitude of couplings and fittings designed only for a single type of fuel. The kit includes a drop-elbow coupler, a storage-tank inlet tube, a primary key slot, a primary key protrusion, a retractable pull pin, a hose, a gravity-drop tube fitting, a secondary key slot, and a secondary key protrusion. The primary key slot traverses into an internal surface of the drop-elbow coupler. The primary key protrusion is externally and laterally connected to the storage-tank inlet tube. The storage-tank inlet tube is positioned within the drop-elbow coupler with the primary key protrusion being positioned within the primary key slot. The secondary key slot traverses into a first female coupler tube of the hose. The secondary key protrusion is externally connected to the gravity-drop tube fitting. This allows the first female coupler tube to fit over the gravity-drop tube fitting.
