The invention discloses auxiliaries of an X-ray mammary machine, and in particular discloses a tube stand positioning device for the X-ray mammary machine. The tube stand positioning device for the X-ray mammary machine comprises a base and a frame, wherein a tube stand is arranged on the frame. The device is characterized in that: the tube stand is arranged on the frame through a main connectingshaft; the rear side of the main connecting shaft and an electromagnetic locking device on the frame are connected; the front side of the main connecting shaft is provided with a disc positioning device; and an electronic control device is arranged in the tube stand. The tube stand positioning device for the X-ray mammary machine ensures that the tube stand is accurately positioned and locked, can display the angle position of the tube stand after external force acts on the tube stand, and can accurately indicate the angle position of the tube stand by digital display or a luminescent point on a dial scale.
Description
(1) Technical field [0001] The invention relates to an accessory of a mammary gland X-ray machine, in particular to a positioning device for a tube support of a mammary gland X-ray machine. (2) Background technology [0002] At present, as long as the mammography tube bracket is positioned by an electromagnetic system, the positioning device has inaccurate positioning and small braking torque. When an external force acts on it, it will cause the angular position of the positioned bracket to deviate. (3) Contents of the invention [0003] In order to make up for the defects of the prior art, the present invention provides an accurate positioning device for the ball tube bracket of the mammography machine. [0004] The present invention is achieved through the following technical solutions: [0005] A mammography machine tube bracket positioning device, including a base and a frame, the tube bracket is installed on the frame, it is characterized in that: the tube bracket is...
