摘要： A coupling assembly includes: a tubular compression collar having a tubular body made of a resiliently flexible polymeric material and having an interior surface and an opposing exterior surface; an end of a tube disposed within a throughway of the compression collar; and a tube fitting disposed within the passageway of the tube. The tube fitting includes: a tubular stem; a flange radially outwardly projecting from an exterior surface of the stem; and an annular barb encircling and radially outwardly projecting from the exterior surface of the stem, the annular barb including a frustoconical outside face that extends along and outwardly slopes away from the stem as the outside face extends toward the flange. The compression collar radially inwardly compresses the tube against the annular barb of the tube fitting so that a liquid tight seal is formed between the tube and the tube fitting.

摘要： An improved end connector for a high-pressure reinforced hose that is subjected to high frequency of pressure cycles and that provides for a low compression deformation of the reinforced hose is discussed. This unique end connector has a stem and ferrule that includes a gripper or cable lock region near a coupler, or outboard end and a substantially smooth length on an outer diameter (OD) of the stem and ferrule that extends from about the gripper region to a hose receiving, or inboard, end.

摘要： A hose assembly includes a hose, a connector body, and a collar. The connector body has an outer end portion defining a fluid connector, an inner end defining a nose portion received in an inner bore of the hose end portion, and an intermediate portion including first and second annular flanges spaced apart to define a dog lock groove. The collar includes an outer end portion defining an inner radial dog lock received in the dog lock groove, an annular step portion extending radially outward of and axially inward of the dog lock in axial alignment with the first annular flange, and an inner end portion extending radially outward of and axially inward from the step portion, the inner end portion being in radial compression against an outer surface of the hose end portion.

摘要： A sliding sleeve for axially sliding onto an expanded end of an all-plastic pipe or a plastic composite pipe, into which is slid a support body having circumferential external ribs of an connecting element is made of an elastically-deformable polymeric material. The internal surface of the sliding sleeve has an average roughness value Ra in a range starting from 1 μm to half of the average wall thickness of the sliding sleeve. In another embodiment, the inner surface of the sliding sleeve has a plurality of macroscopic irregularities, the depth of which does not exceed half of the average wall thickness of the sliding sleeve.

摘要： 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.

摘要： A toggle-type open-close clamping structural assembly and a pump head of a peristaltic pump comprising same. The toggle-type open-close clamping structural assembly comprises: a lower pipe clamp and an upper pipe clamp (1) that are oppositely arranged and that are used to form a pair of hose clamp hoops; an upper pressure block used for lifting and lowering to open and close; and a driving lever (4) used for enabling the upper pipe clamp (1) to follow the upper pressure block to lift, slip and follow-up. The driving lever (4) is pivotally connected to the upper pressure block. The upper pipe clamp (1) and one end of the driving lever (4) are overlappingly disposed in a clamping port reserved on the upper pressure block, and the other end of the driving lever (4) is abutted against a fixing part (5) that serves as fixing reference. In the lifting process of the upper pressure block, the upper pipe clamp (1) is driven to lift, and meanwhile, the driving lever (4) follows up and rises and lifts up the upper pipe clamp (1), so that the upper pipe clamp (1) is far away from the lower pipe clamp, thereby preventing the driving lever (4) from wear and tear and achieving simple and efficient replacement of hoses.

摘要： A hydraulic adapter unit includes a hose connecting member and a pipe member. The hose connecting member is a substantially cylindrical hose connecting member, and includes: a hose fixing portion positioned at one end side of the hose connecting member and to which the hose is fixed; a first combining portion positioned at the other end side of the hose connecting member; and an intermediate portion linking the hose fixing portion and the first combining portion. The pipe member includes: a substantially tubular pipe body; a second combining portion disposed at the one end side of the pipe body and separably combined to the first combining portion of the hose connecting member; and a flange portion disposed at the other end side of the pipe body and formed so as to project outward in the radial direction of the pipe body and fixed to a hydraulic device.
