Quick lock release coupling

A quick release coupling for providing a connection between a pair of hydraulic lines, the quick release coupling comprising:

• a male component having a fluid passage therethrough and comprising:
• a shank portion adapted to engage a first hydraulic line, the shank portion having a first port adapted to establish fluid communication between the first hydraulic line of the pair of hydraulic lines and the fluid passage, the shank portion comprising a restraining mechanism adapted to cooperatively engage the first hydraulic line and block a rotational movement and an axial movement of the male component relative to the first hydraulic line when engaged with the first hydraulic line;
• and
• a coupling adapter connectable to the male component and having a fluid channel therethrough adapted to be in fluid communication with the fluid passage, the coupling adapter being adapted to engage a second hydraulic line of the pair of hydraulic lines and comprising a second port adapted to establish fluid communication between the second hydraulic line and the fluid channel, the coupling adapter further comprising a housing having internal surfaces defining a cavity having an open end, wherein the male component is shaped and sized to engage the cavity via the open end and abut at least one of the internal surfaces;
• and
• a nut securable within the cavity of the housing and surrounding a section of the shank portion to radially restrain the male component, the nut being adapted to axially restrain the male component within the cavity and allow the male component to rotate with respect to the housing and the nut about a longitudinal axis of the shank portion, thereby enabling the first and second fluid lines to be swivellably interconnected.

• a coupling adapter comprising a housing shaped and adapted to receive the male component therein and having a fluid channel therethrough adapted to be in fluid communication with the fluid passage, the coupling adapter being configured to axially restrain the male component while enabling rotational movement of the male component within a cavity and about a longitudinal axis of the shank portion,
• the coupling adapter being adapted to engage a second hydraulic line of the pair of hydraulic lines such that the first and second hydraulic lines are swivellably connected, the coupling adapter further comprising a second port adapted to establish fluid communication between the second hydraulic line and the fluid channel.
