Description

Technical Field

[0001] This utility model relates to the technical field of C-arm adjustment equipment, specifically a C-arm angle adjustment device. Background Technology

[0002] C-arms typically refer to support structures in the field of medical imaging. Because their shape resembles the English letter "C," C-arms allow for easy manipulation of imaging equipment and adjustment of the image angle, thus facilitating the adaptation of imaging equipment to different needs. A C-arm angle adjustment device is a device used to adjust the angle of the C-arm during processing, thereby adjusting the spatial posture of the C-arm to facilitate processing.

[0003] However, existing C-arm angle adjustment devices have the following problems when in use:

[0004] To facilitate the processing of C-arms, it is necessary to adjust the angle not only by rotating the C-arm laterally, but also by rotating it longitudinally. However, existing C-arm angle adjustment devices do not allow for longitudinal rotation of the C-arm, making it difficult to adjust the angle in the vertical direction, thus increasing the limitations of the device's use.

[0005] To address the aforementioned issues, there is an urgent need for innovative design based on the existing C-arm angle adjustment device. Utility Model Content

[0006] The purpose of this invention is to provide a C-arm angle adjustment device to solve the problem mentioned in the background art that the existing C-arm angle adjustment devices are inconvenient to rotate the C-arm longitudinally, making it difficult to adjust the angle of the C-arm in the vertical direction, thus increasing the limitations of the device's use.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a C-arm angle adjustment device, comprising a base plate, a main servo motor, an electric telescopic rod, a dual-head servo motor, and a sprocket mechanism. The main servo motor is installed at the center of the upper surface of the base plate, and a square rod is fixedly connected to the upper end of the output shaft of the main servo motor. An inner square sleeve is fitted on the outer wall of the square rod, and a bracket is fixedly connected to the upper end of the inner square sleeve. Electric telescopic rods are respectively provided at both ends of the lower surface of the bracket, and a support wheel is installed at the end of the output shaft of the electric telescopic rod. A dual-head servo motor is provided at the middle of the upper surface of the bracket, and transmission rods are fixed at both ends of the output shaft of the dual-head servo motor. A positioning groove is provided above the dual-head servo motor, and support rods are fixed at both ends of the positioning groove. Gears are fixedly connected to the outer wall of the support rods, and a limit mechanism is provided on the bracket surface on the side of the support rods.

[0008] Preferably, the inner square sleeve and the square rod form a sliding structure, and the support wheel and the base plate are in contact.

[0009] Preferably, both the transmission rod and the support rod form a rotating structure with the bracket, and the outer wall of the transmission rod is connected to the outer wall of the support rod through a sprocket mechanism.

[0010] Preferably, the limiting mechanism includes a knob and a toothed plate, with the knob movably mounted on the upper surface of the bracket, and the toothed plate sleeved on the outer wall of the knob.

[0011] Preferably, the knob and the bracket are rotatably connected, and the knob and the toothed plate are threaded together.

[0012] Preferably, the toothed plate and the bracket are slidably arranged, and the toothed plate and the gear mesh with each other.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the C-arm angle adjustment device facilitates the longitudinal rotation of the C-arm, making it easy to adjust the angle of the C-arm in the vertical direction, thereby increasing the flexibility of the device.

[0014] The dual-head servo motor drives the transmission rod, which in turn drives the sprocket mechanism to drive the support rod. The support rod then drives the positioning groove to rotate, thereby rotating the C-arm to adjust its vertical angle. Therefore, the device allows for easy longitudinal rotation of the C-arm, making it convenient to adjust the vertical angle of the C-arm and increasing the device's flexibility of use.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4 This utility model provides a technical solution: a C-arm angle adjustment device, including a base plate 1, a main servo motor 2, a square rod 3, an inner square sleeve 4, a bracket 5, an electric telescopic rod 6, a support wheel 7, a dual-head servo motor 8, a transmission rod 9, a positioning groove 10, a support rod 11, a gear 12, a sprocket mechanism 13, a limiting mechanism 14, a knob 1401, and a toothed plate 1402. The main servo motor 2 is installed at the center of the upper surface of the base plate 1, and the upper end of the output shaft of the main servo motor 2 is fixedly connected to the square rod 3. The outer wall of the square rod 3 is fitted with an inner square sleeve 4. A bracket 5 is fixedly connected to the upper end of the bracket 4. Electric telescopic rods 6 are respectively provided at both ends of the lower surface of the bracket 5. A support wheel 7 is installed at the end of the output shaft of the electric telescopic rod 6. A dual-head servo motor 8 is provided in the middle of the upper surface of the bracket 5. A transmission rod 9 is fixed at both ends of the output shaft of the dual-head servo motor 8. A positioning groove 10 is provided above the dual-head servo motor 8. A support rod 11 is fixed at both ends of the positioning groove 10. A gear 12 is fixedly connected to the outer wall of the support rod 11. A limit mechanism 14 is provided on the surface of the bracket 5 on the side of the support rod 11.

[0022] The inner square sleeve 4 and the square rod 3 form a sliding structure. The support wheel 7 is in contact with the base plate 1. When the height of the device is adjusted, the bracket 5 drives the inner square sleeve 4 to slide relative to the square rod 3. At the same time, it is convenient for the square rod 3 to drive the inner square sleeve 4 to rotate. When the bracket 5 rotates to adjust the horizontal angle of the C-shaped arm, the electric telescopic rod 6 drives the support wheel 7 to move relative to the base plate 1, thereby making the base plate 1 move stably.

[0023] Both the transmission rod 9 and the support rod 11 form a rotating structure with the bracket 5. The outer wall of the transmission rod 9 is connected to the outer wall of the support rod 11 through the sprocket mechanism 13, which facilitates the dual-head servo motor 8 to drive the transmission rod 9 to rotate. This allows the transmission rod 9 to drive the support rod 11 to rotate through the sprocket mechanism 13, thereby causing the positioning groove 10 to drive the C-shaped arm to rotate and adjust the vertical angle of the C-shaped arm.

[0024] The limiting mechanism 14 includes a knob 1401 and a toothed plate 1402. The knob 1401 is movably mounted on the upper surface of the bracket 5, and the toothed plate 1402 is sleeved on the outer wall of the knob 1401, so as to lock the gear 12 through the limiting mechanism 14, thereby ensuring the stability of the positioning groove 10.

[0025] The knob 1401 and the bracket 5 are rotatably connected, and the knob 1401 and the toothed plate 1402 are threaded together, which makes it easy for the user to rotate the knob 1401 so that the toothed plate 1402 moves relative to the knob 1401.

[0026] The toothed plate 1402 and the bracket 5 are slidably arranged, and the toothed plate 1402 and the gear 12 mesh with each other, so that the toothed plate 1402 can slide relative to the bracket 5 to mesh with the gear 12, thereby limiting the positioning groove 10.

[0027] Working principle: When using this C-arm angle adjustment device, firstly as follows... Figure 1-4 As shown, the user places the C-arm into the positioning groove 10, then starts the main servo motor 2. The main servo motor 2 then drives the square rod 3 to rotate, followed by the square rod 3 driving the inner square sleeve 4 to rotate. The inner square sleeve 4 then drives the bracket 5 to rotate, which in turn drives the positioning groove 10 to rotate, thus allowing the C-arm to rotate laterally for horizontal angle adjustment. Simultaneously, as the bracket 5 rotates, the electric telescopic rod 6 drives the support wheel 7 to move relative to the base plate 1, ensuring the stability of the C-arm's lateral rotation. Then, the user starts the dual-head servo motor 8, which drives the transmission rod 9 to rotate. The transmission rod 9 then drives the support rod 11 to rotate via the sprocket mechanism 13, which in turn drives the positioning groove 10 to rotate, thus allowing the C-arm to rotate longitudinally. The vertical angle is adjusted. After the vertical angle of the C-arm is adjusted, the user rotates the knob 1401. Then, the toothed plate 1402 moves down relative to the knob 1401 and slides down relative to the bracket 5. Next, the toothed plate 1402 moves and meshes with the gear 12, thereby limiting the gear 12 to ensure the stability of the positioning groove 10. Therefore, the device facilitates the longitudinal rotation of the C-arm, making it easy to adjust the vertical angle of the C-arm, thus increasing the flexibility of the device. Then, when the height of the device needs to be adjusted, the user activates the electric telescopic rod 6. At this time, the electric telescopic rod 6 pushes the bracket 5 upward to adjust the height of the device. As the bracket 5 moves, the bracket 5 drives the inner square sleeve 4 to slide relative to the square rod 3. Therefore, the device is easy to adjust the height and improves its practicality.

[0028] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
