Abstract
The present invention provides a latching mechanism for an x-ray tube assembly comprising a rotary plate, a first spring-loaded latch and a second spring-loaded latch which are disposed diametrically. The rotary plate comprises a first receiving portion and a second receiving portion spaced from each other by 90°. The first spring-loaded latch configured to be pressed removably into the first receiving portion to lock the x-ray tube assembly in a first position and the second spring-loaded latch is configured to be pressed removably into the second receiving portion to lock the x-ray tube assembly in a second position. According to the present invention, it is possible tomake manufacturing tolerance control and assembly of the x-ray imaging system much simpler and easier.
Claims13
A latching mechanism for an x-ray tube assembly comprising:
- a rotary plate to which the x-ray tube assembly is fixedly mounted by means of a tube arm, the rotary plate being rotatably mounted to a supporting part to be rotatable about an axis relative to the supporting part, the axis passing through a point on the rotary plate perpendicularly to the rotary plate, the rotary plate comprising a first receiving portion and a second receiving portion, the second receiving portion being spaced from the first receiving portion by substantially 90° about the axis;
- and
- a first spring-loaded latch and a second spring-loaded latch which are fixed on the supporting part, the first spring-loaded latch (and the second spring-loaded latch being disposed diametrically and adjacent the rotary plate, the first spring-loaded latch being configured to be pressed removably into the first receiving portion to lock the x-ray tube assembly in a first position, the second spring-loaded latch being configured to be pressed removably into the second receiving portion to lock the x-ray tube assembly in a second position which is spaced from the first position by substantially 90° about the axis in a first direction.
