Technical Field

[0001] The utility model mainly relates to the technical field of radiological imaging diagnosis equipment, and specifically relates to a two-position radiography stand for a mobile DR detector. Background Technique

[0002] Mobile DR, also known as a mobile X-ray machine, is a medical device that can emit X-rays and perform radiological examinations and radiological treatments on human tissues. Since the mobile DR can be moved, it is very convenient to use. Doctors can move the mobile DR to the ward according to needs for diagnosing or treating patients who are not easy to move. The mobile DR generally consists of main components such as a vehicle body, a host, a radiography stand, and a detector. The radiography stand is fixedly installed on a connecting seat on the vehicle body of the mobile DR. A detector that can move up and down is provided on the radiography stand, and the detector can be operated through the host.

[0003] The radiography stand mainly cooperates with the detector and can perform X-ray photography on various parts of the human body such as the head, chest, abdomen, and joints. In the existing radiography stands for mobile DR detectors, most radiography stands can only achieve single-position radiography and cannot meet the radiography requirements of multiple positions, which to a certain extent limits the use range and use efficiency of the mobile DR detector.

A through groove is opened on the front surface of the column. A first stepping motor is fixedly installed on the bottom surface of the inner wall of the column. A screw rod is fixedly installed at the output end of the first stepping motor. A slider is slidably fitted and installed inside the column. A threaded hole that is threadedly engaged with the screw rod is opened at the center of the top surface of the slider. A connecting plate is provided in front of the slider. A second stepping motor is fixedly installed on the front surface of the connecting plate. A connecting rod is fixedly installed at the output end of the second stepping motor. A detector is fixedly installed at the front end of the connecting rod.

The movable ends of the electric telescopic rods are fixedly connected to the rear surface of the connecting plate.

[0007] Further, a limiting plate is fixedly installed inside the U-shaped frame. The front surface of the limiting plate is slidably fitted with the rear surface of the column.

[0008] Further, a ray shielding plate is fixedly installed at the back of the two rectangular blocks, and a cross-shaped mark is provided at the back of the ray shielding plate.

[0009] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0010] When the device is in use, through the mutual cooperation of the second stepping motor, the connecting rod and the detector, the rotation of the output shaft of the second stepping motor can realize the adjustment of the angle of the detector, so as to realize the shooting requirements in the vertical and horizontal directions of the detector, and the detector can meet the radiography requirements at multiple angles, greatly improving the practicability of the device.

[0021] A connecting block 12 is fixedly installed in front of the slider 6, a U-shaped frame 13 is fixedly installed on the front surface of the connecting block 12, rectangular blocks 14 are fixedly installed at the rear parts on both sides of the U-shaped frame 13, electric telescopic rods 15 are respectively fixedly installed on the front surfaces of the rectangular blocks 14, the electric telescopic rods 15 are electrically connected to a power source, and the movable ends of the electric telescopic rods 15 are fixedly connected to the rear surface of the connecting plate 8. When this structural design is in use, the support of the electric telescopic rods 15 can be realized through the mutual cooperation of the U-shaped frame 13 and the rectangular blocks 14. When in use, through the telescopic movement of the movable rods of the electric telescopic rods 15, the electric telescopic rods 15 can drive the connecting plate 8 to move back and forth through the connecting blocks 12 and the U-shaped frame 13 connected thereto, so as to realize the back-and-forth movement of the horizontal position of the detector 11, which is convenient for the user to adjust the horizontal position of the detector 11 and is convenient for use.

[0022] A limiting plate 16 is fixedly installed inside the U-shaped frame 13, both ends of the limiting plate 16 are fixedly connected to the corresponding inner surfaces of the U-shaped frame 13, and the front surface of the limiting plate 16 is slidably fitted with the rear surface of the column 2.

[0024] Working principle:

[0025] This device can be fixedly installed on the connecting seat of the mobile DR through bolts, and then powered by a power supply. When in use, the rotation of the output shaft of the first stepping motor 4 can drive the screw rod 5 to rotate. Since the screw hole 7 on the top surface of the slider 6 is in threaded engagement with the screw rod 5, when the screw rod 5 rotates, the slider 6 can move up and down in the column 2, thereby driving the connecting plate 8, the second stepping motor 9, the connecting rod 10 and the detector 11 to move up and down, realizing the adjustment of the vertical position of the detector 11. At the same time, the rotation of the output shaft of the second stepping motor 9 can drive the connecting rod 10 and the detector 11 to rotate, thereby realizing the adjustment of the horizontal position of the detector 11. In addition, through the telescopic movement of the movable rod of the electric telescopic rod 15, the electric telescopic rod 15 can drive the connecting plate 8 to move back and forth through the connecting block 12 and the U-shaped frame 13 connected thereto, thereby realizing the forward and backward movement of the horizontal position of the detector 11. Therefore, this device can meet the radiography requirements of the detector 11 at multiple angles and horizontal positions, greatly improving the practicability of this device.

[0026] In summary, the double-position radiography rack for a mobile DR detector provided by the present utility model has the advantages of simple structure, convenient use, strong practicability, etc., can meet the radiography needs of different users, improve the radiography efficiency, and has high practical value and promotion value.
