Description

Technical Field

[0001] The present invention relates to the technical field of medical equipment, and in particular to a beam control device in an X-ray machine. Background Art

[0002] The beam splitter is generally installed in front of the output window of the tube assembly sleeve of the X-ray medical equipment to simulate the radiation area of ​​the X-ray and avoid unnecessary additional doses for the patient. The beam splitter currently used in the X-ray machine is a double-door linkage structure. The two sliding doors are controlled by two independent screws respectively. It is difficult to synchronously adjust the movement of the shielding block, which may cause the radiation dose to be too large or too small. In addition, the self-locking stability of the single screw is not high, and it is easy to rotate due to vibration, which causes the shielding plate to be offset and reduces the shielding accuracy. When the beam splitter is installed, it is also difficult to adapt to the fixed installation of sleeves with different aperture sizes.

[0003] For example, a beam guide control device in an X-ray machine with announcement number CN217244465U, the control device includes a left guide rail, a left slider slidably arranged on the left guide rail, a right guide rail parallel to and located at the same height as the left guide rail, a right slider slidably arranged on the right guide rail, a left sliding door fixedly arranged on the left slider, a right sliding door fixedly arranged on the right slider, a vertical lead screw between the left guide rail and the right guide rail, a nut sleeved on the lead screw and threadedly connected to the lead screw, a first connecting rod rotatably connected between the nut and the left slider, and a second connecting rod rotatably connected between the nut and the right slider. However, after the device is adjusted, it is not convenient to firmly position the lead screw, so that when the subsequent equipment is vibrated during use, the lead screw is easy to rotate, thereby causing the shielding plate to be offset, resulting in excessive or insufficient radiation dose, and it is difficult to adapt to the installation and use of sleeves with different aperture sizes.

[0004] Therefore, a beam guide control device in an X-ray machine is proposed to solve the above-mentioned problems. Summary of the invention
