Abstract
The invention relates to a quick release coupling device comprising an annular groove (4) formed on the inner face of one of the hollow bodies, a projecting part (6) formed on the other hollow body (2) and a force transmitting member (5) engaged with the groove and the projecting part (6). A shoulder (23) is provided for fixing the force transmitting member (5) to hinder the loosening of the coupling under loading. The inventive device is advantageous in that its design and use are straightforward while meeting the requirements related to safety and ease of cleaning.
Claims8
A quick release coupling device for hollow bodies subjected to a pressure, the device comprising an annular groove (4) formed on an inner side of a hollow body (1), a projection (6) formed on another hollow body (2), and at least one force transmitting member (5) which engages both the groove and the projection,
- wherein a shoulder (23, 25) is formed in the groove (4) or on the force transmitting member (5) in order to secure the force transmitting member, and
- wherein the device further comprises a retaining member secured on the hollow body, a cam plate adjustably arranged on the retaining member, and two levers pivotally arranged on the retaining member and connected with the force transmitting member engaging the same in order to compress or expand the force transmitting member and to lock it in a respective end position, and an arrangement of channels for a pressurized medium for displacing the force transmitting member in an operational position.
A quick release coupling device for hollow bodies subjected to a pressure, which device includes an annular groove (4) formed on an inner side of a hollow body (1), a projection (6) formed on another hollow body (2), and at least one force transmitting member (5) which engages both the groove and the projection,
- wherein a shoulder (23, 25) is formed in the groove (4) or on the force transmitting member (5), in order to secure the force transmitting member, and
- wherein the device further comprises a retaining member secured on the hollow body, a cam plate adjustably arranged on the retaining member, and two levers pivotally arranged on the retaining member and connected with the force transmitting member engaging the same in order to compress or expand the force transmitting member and to lock it in a respective end position, and means for monitoring the force transmitting member which means is formed as a scanning member arranged in an operational contact with the force transmitting member and provided with a signal pick-up for outputting a position of the force transmitting member.
A quick release coupling device for hollow bodies subjected to a pressure, which device includes an annual groove (4) formed on an inner side of one hollow body (1), a projection (6) formed on another hollow body (2), and at least one force transmitting member (5) which engages both the groove and the projection,
- wherein a shoulder (23, 25) is formed in the groove (4) for securing the force transmitting member (5) in a predetermined radial position when the hollow bodies (1,2) are subjected to the pressure, and
- wherein the force transmitting member is formed with inclined surfaces (22) providing for a pivotal movement of the force transmitting member relative to the groove which insures an interlocking engagement of the force transmitting member with the shoulder when the hollow bodies are subjected to the pressure.
