A device, a method and an x-ray system for locking and unlocking a position of an x-ray tube head

A device for locking and unlocking a position of an X-ray tube head, comprising:

• a housing arranged and configured for being connected to a telescope column of an X-ray system;
• a first engagement element and a second engagement element;
• a first contact element configured to engage with the first engagement element;
• a second contact element configured to engage with the second engagement element;
• a cam element, which is movably provided, wherein the first and the second contact element are attached at opposite positions on a same surface of the cam element;
• an actuator and a spring attached to the cam element, wherein the cam element is arranged between the actuator and the spring;
• a rotating disk arranged in the housing, the rotating disk comprising a plate and a shaft, wherein the shaft is configured to be attached to the X-ray tube head, wherein the rotating disk is arranged to support the cam element, the first contact element and the second contact element when being moved;
• wherein the first and second engagement element, the first and second contact element, the cam element, the actuator and the spring are arranged inside of the housing;
• wherein the first contact element and the second contact element are configured for being movable by the cam element;
• wherein the first contact element and the second contact element are configured for being movable between a locking position and an unlocking position;
• wherein in the locking position the first contact element engages with the first engagement element and the second contact element engages with the second engagement element;
• wherein in the unlocking position the first contact element is spaced apart from the first engagement element and the second contact element is spaced apart from the second engagement element;
• wherein the actuator is configured upon activation to rotate the cam element such that the cam element is configured to move the first and the second contact element from the locking position to the unlocking position, such that the spring is configured to move due to the rotation of the cam element;
• wherein the spring is configured, upon deactivation of the actuator, to rotate the cam element due to a reset force of the spring such that the cam element is configured to move the first contact element and the second contact element from the unlocking position to the locking position.
