A temperature-controlled fluid processing system with accessory attachment mechanism includes an accessory annular ring feature a mounting surface and a tapered surface sloping toward a central axis of the ring feature and away from the mounting surface, and engaging components on the primary device, including concentric annular member and rotation plate. The annular member includes spaced apart through holes housing spring biased pins. The rotation plate surrounds the annular member, and includes one or more ramped inner surface(s). The plate is rotatable between an unattached position wherein the ramped surfaces apply no radial inward force to the spring-biased pins, and an attached position wherein each ramped surface displaces a pin inward through its corresponding through hole such that the conical tip of the spring-biased pin engages the tapered surface of the ring feature, thereby immobilizing the accessory with respect to a head unit of the fluid processing device.

A housing assembly comprising a housing that has at least one first connection opening and one second connection opening, a first connecting piece with a first flange and a second connecting piece with a second flange. The first connecting piece is connected to the first connection opening and the second connecting piece is connected to the second connection opening. The housing additionally has a projection with an overhang. The A locking part of the first flange is arranged in locking engagement with the overhang, and the first flange and the second flange are configured in such a way and arranged with respect to one another that a turning of the first flange is prevented by the second flange. A corresponding method of fixing multiple connections to a housing is also provided.

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.

Disclosed is a quick-disassembly nipple connector structure, which is mainly composed of a pipe, a pivoting assembly, a screwing member, a plurality of gripping jaws, a sleeve and a handle. The handle can be pulled by users to enable the quick-disassembly nipple connector structure to be rapidly connected to or separated from a grease nipple. When the handle is pulled downwards, the sleeve is located at a lock position to lock the grease nipple; and when the handle is pulled upwards, the sleeve is located at a release position to release the grease nipple. Thus, the quick-disassembly nipple connector structure has the advantages of being capable of improving work efficiency, high in positioning speed, high in accuracy and good in fixing property and has a good overall constituent strength, so that the motion stability is improved, and the operation smoothness and service life are ensured.

A valve connector for a high pressure air pump includes an outer sleeve having opposite first and second ends. The outer sleeve includes a coupling hole extending along a rotating axis and a receiving space intercommunicating with the coupling hole and located adjacent to the first end of the outer sleeve. An abutting member includes an abutting end received in the receiving space and a connecting end opposite to the abutting end. The abutting member includes an inlet passageway intercommunicating with the abutting end and the connecting end. An outer periphery of an airtight member about the rotating axis slidably abuts and is in airtight contact with an inner periphery of the receiving space. The airtight member is movable toward the first end or the second end. The airtight end face is configured to be biased toward the first end by air current entering from the inlet passageway.

A quick connector assembly includes a male adapter portion (24) having an end and a groove (62) formed therein spaced from the end. The male adapter portion has a through bore. A female housing portion (22) has a body having a through bore generally concentrically aligned with the male adapter portion through bore. A ring (26) cooperates with the female housing portion and the male adapter portion. The ring is in a first position when the male adapter is engaged with the female housing and a second position, different from the first position, when the male adapter is other than engaged with the female housing. The first and second positions can be visually different from one another.

A securing device comprises a collar for releasably clamping first, and second objects (28,30) together, wherein the collar includes a pair of collar members (46), each of the collar members (46) being pivotably coupled to the other collar member (46) at or towards a first end so as to allow pivotable movement of the collar members (46) relative to each other, the collar including a releasable securing member (42) that includes securing member portions respectively arranged in or on the collar members (46) at or towards their other second ends, wherein the securing member portions are configured to be coaxially connectable to each other to secure the collar members (46) to each other at or towards their other second ends, and the securing member portions are configured to be coaxially disconnectable from each other to permit separation of the second ends of the collar members (46).

A fluid connection assembly, including a connector body, including a first end, a second end, a first through-bore, a first radially outward facing surface including at least one aperture extending from the first radially outward facing surface to the first through-bore, and at least one detent arranged in the at least one aperture, and a collar connected to the connector body, the collar including a first section non-rotatably connected to the connector body, and a second section including a radially inward facing surface engaged with the first radially outward facing surface and including at least one pocket extending radially outward therefrom, wherein the second section is engaged with and rotatable with respect to the first section.

A joint assembly for connecting a first pipe having a first inner diameter and a second pipe having a second inner diameter which is larger than the first inner diameter comprises, an annular section comprising an annular wall defining a flow path through the annular section and configured to connect to the first pipe and the second pipe, and a clamp portion configured to clamp the second pipe between an outer surface of the annular section and an inner surface of the clamp portion. An inner diameter of the annular section varies from a first inner diameter at a first end of the annular section to a second inner diameter at a second end of the annular section. The first inner diameter is substantially equal to the inner diameter of the first pipe. The second inner diameter is substantially equal to the inner diameter of the second pipe.
