Description

Technical Field

[0001] The utility model belongs to the technical field of imaging equipment, and more specifically, particularly relates to a rapid scanning and positioning device for imaging equipment. Background Art

[0002] With the rapid development of medical technology, people's ability to treat diseases has been greatly improved, and people's health has been guaranteed. The development of medical care is inseparable from the assistance of many medical equipment. Nowadays, imaging equipment is used to scan the patient's body, and stepper motors are used to drive the imaging equipment for mobile scanning. At the same time, the imaging equipment is positioned by controlling the shutdown of the stepper motor, so as to obtain the internal situation of the patient's body, to assist doctors in better diagnosing the patient's disease, and then to come up with a more accurate treatment plan.

[0003] The existing publication number CN220046404U discloses a rapid scanning and positioning device for imaging equipment. Although the height of the climbing and lying pillow is adjusted by arranging grooves with different heights on the bearing column, the patient can breathe smoothly when lying on the testing table. The use of an adjustment frame to adjust the pillow height is low-cost and easy to promote.

[0004] Based on the above, the inventors have discovered the following problems: However, the device controls the horizontal movement of the imaging device by using a screw rod and a slide. Since the imaging device moves frequently, the screw rod and the slide need to be lubricated for a long time. Otherwise, they will easily get stuck, causing the imaging device to stop moving, which is inconvenient for long-term use. At the same time, two electronic push rods are used to adjust the horizontal height of the imaging device. If the two electronic push rods have different pushing speeds or pushing times, they are also prone to getting stuck.

[0005] Therefore, in view of this, the existing structure and defects are studied and improved, and a fast scanning and positioning device for imaging equipment is provided, in order to achieve a more practical purpose. Utility Model Content

[0006] In order to solve the above technical problems, the utility model provides a rapid scanning and positioning device for imaging equipment to solve the problem that current imaging equipment moves frequently, resulting in a long-term need to lubricate the screw rod and the slide, otherwise it will easily get stuck, causing the imaging equipment to stop moving and being inconvenient to use for a long time.

[0029] Among them, one of the pulleys 7 is fixed to the rotating shaft 6, and the other pulley 7 is rotatably connected to one end of one side of the groove 3. The first servo motor 5 rotates, driving the rotating shaft 6 and the pulley 7 fixed thereto to rotate, thereby driving the other pulley 7 and the transmission belt 8 to rotate.

[0030] Among them, four moving wheels 15 are provided, and the four moving wheels 15 are respectively located at the two ends of the bottom of the moving rod 17 in groups of two.
