DEVICE FOR CONNECTING TWO TUBULAR PRODUCTS Russian patent published in 2023 - IPC F16L37/98 

FIELD: mechanics.

SUBSTANCE: invention relates to a device for connecting two tubular products, which has a body for the connecting part and a fastener, while the fastener has a shape complementary to the receiving hole of the specified body, and is adapted for rotation in the specified hole. The fastener has a mounting hole designed to receive the connecting part, as well as locking tabs, which are spaced from each other in the circumferential direction and each of which has a locking part facing inward in the radial direction and designed to engage with the shaped elements of the connecting part, and is adapted to move from the first radial position to the second radial position located outside in the radial direction. For each locking tab, said housing has an inclined surface that is bevelled inwards in the radial direction and on which the locking tab rests, the inclined surface and the supporting surface being shaped such that when the fastener is rotated in the first direction, the locking tabs are pushed into the second radial position, and in the unloaded state, the fastener rotates back in a second direction opposite to the first direction, as a result of the movement of the locking tabs back to the first position under the action of an elastic force.

EFFECT: invention provides reliable fixation performed without excessive efforts.
