Description

Technical Field

[0001] This utility model relates to the field of CT machine technology, and in particular to a CT machine performance testing phantom support. Background Technology

[0002] With the continuous development of medical imaging technology, CT (computed tomography) machines are increasingly widely used in medical diagnosis. To ensure the accurate and stable operation of CT machines during use, regular performance testing is essential. During testing, phantoms are often used to simulate human tissue or specific imaging conditions to verify the performance indicators of the CT equipment, such as image clarity, uniformity, and resolution. However, during testing, a support frame is usually needed to support the phantom. Because the performance testing phantom is relatively heavy, using a support frame may make it difficult to retrieve, or even cause it to fall and collide with personnel, affecting safety. Utility Model Content

[0003] The purpose of this utility model is to solve the technical problems mentioned in the background art.

[0004] This utility model adopts the following technical solution: a CT machine performance testing phantom support, including a phantom box, a support plate, and a placement plate. A slide rail is fixedly installed inside the phantom box, and a slider is slidably connected to the inner side of the slide rail. A lower connecting seat is fixedly installed on the surface of the slider. An upper connecting seat is fixedly installed on the bottom surface of the support plate. A connecting rod is rotatably connected between the upper and lower connecting seats. A vertical plate is fixedly installed on the surface of the placement plate, and a support frame is fixedly installed on the side of the vertical plate. An adjusting plate is slidably connected inside the support frame. A cylinder is fixedly installed on the surface of the adjusting plate, and a pull plate is fixedly installed at the top of the cylinder. A spring is sleeved on the surface of the cylinder. A positioning rod is fixedly installed on the bottom surface of the adjusting plate. A through hole is opened on the surface of the placement plate, and a first positioning hole and a second positioning hole are opened on the surface of the support plate.

[0005] Preferably, the number of connecting rods is four sets, and the four sets of connecting rods are symmetrically distributed at the bottom of the support plate. This can enhance the stability and balance of the support plate when sliding inside the mold box, avoid tilting or instability caused by uneven force on one side, thereby improving the overall reliability and accuracy of the equipment and ensuring the stable positioning of the mold during CT machine performance testing.

[0006] Preferably, a drive block is fixedly mounted on the surface of the slider, a motor is fixedly mounted on the side of the mold box, and a bidirectional lead screw is fixedly mounted on the output end of the motor. The bidirectional lead screw is threadedly connected inside the drive block. Here, the motor drives the bidirectional lead screw to rotate, and the drive block moves on the surface of the bidirectional lead screw, thereby driving the slider to move inside the slide rail. This improves the convenience and accuracy of operation, and the bidirectional lead screw can provide smoother movement.

[0007] Preferably, a limiting block is fixedly installed at the bottom of the upright plate, and a limiting groove is fixedly installed on the surface of the support plate, with the limiting block slidably connected inside the limiting groove. Here, on the surface of the support plate, a mounting plate is slidable off the surface of the support plate, thereby removing the mold placed on the mounting plate from the mold box, thus facilitating personnel to use the mold to perform performance testing on the CT machine.

[0008] Preferably, the first positioning hole and the second positioning hole are located at opposite ends of the support plate surface, and the diameters of the positioning rod, the first positioning hole, and the second positioning hole are identical. Here, the positioning rod engages with the first positioning hole and the second positioning hole respectively, allowing the mold body to be stored or slid out onto the support plate surface. This simplifies the switching and fixing of the mold body between different positions, ensuring accurate and consistent positioning each time and reducing errors caused by inaccurate positioning.

[0009] Preferably, a short shaft is fixedly mounted on the side of the shelf, and a support rod is rotatably connected to the surface of the short shaft. A circular hole is formed on the surface of the support rod, and a screw is inserted into the hole. A first screw hole is formed on the side of the shelf, and the screw is threaded into the first screw hole. A connecting block is fixedly mounted on the side of the mold box, and a second screw hole is formed on the surface of the connecting block. The second screw hole has the same size as the first screw hole. Here, when the mold slides out of the mold box, the support rod on the side of the shelf connects with the connecting block on the side of the mold box, which improves the load-bearing capacity of the mold on the shelf and prevents the shelf from bending due to excessive force during use.

[0010] Preferably, the number of support rods is two sets, and the two sets of support rods are symmetrically distributed on both sides of the shelf. Here, the support rods are symmetrically distributed on both sides of the shelf, which can evenly support and distribute the load, avoid deformation or tilting caused by excessive force on one side, not only improve the overall balance, but also further enhance the structural strength of the support.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0012] 1. In this utility model, a motor drives a bidirectional lead screw to rotate, enabling the slider to move on the slide rail. Through the cooperation of the connecting rod, upper connecting seat, and lower connecting seat, the support plate can extend from the mold box. The use of four symmetrically distributed sets of connecting rods enhances the stability and balance of the support plate sliding inside the mold box, avoiding tilting or instability caused by uneven force on one side. When the pull plate is pulled, the pull plate drives the positioning rod at the bottom of the adjusting plate to disengage from the No. 1 positioning hole, thereby allowing the placement plate to move on the support plate. Subsequently, the mold on the placement plate can be extended, making it convenient for the operator to extend the mold from the mold box when using the mold and to store the mold back in the mold box when not in use, thus improving the convenience of CT machine performance testing.

[0013] 2. In this utility model, the symmetrically distributed support rods on both sides of the shelf enhance the load-bearing capacity, effectively distribute the load, and avoid deformation or tilting caused by excessive force on one side. This not only improves the overall balance but also enhances the strength of the support structure. Furthermore, the coordinated use of the short shaft, support rods, and connecting blocks makes the mold slide out of the mold box more smoothly, simplifies operation, and increases reliability. This reduces the risk of the mold slipping due to shelf deformation, further improving the safety and testing effectiveness of the equipment. Attached Figure Description

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Example 1

[0024] Please see Figure 1-4This utility model provides a technical solution: a CT scanner performance testing phantom support, including a phantom box 1, a support plate 7, and a placement plate 11. A slide rail 2 is fixedly installed inside the phantom box 1, and a slider 3 is slidably connected to the inner side of the slide rail 2. A lower connecting seat 4 is fixedly installed on the surface of the slider 3. An upper connecting seat 6 is fixedly installed on the bottom surface of the support plate 7. A connecting rod 5 is rotatably connected between the upper connecting seat 6 and the lower connecting seat 4. There are four sets of connecting rods 5, symmetrically distributed at the bottom of the support plate 7. This enhances the stability and balance of the support plate 7 when sliding inside the phantom box 1, avoiding tilting or instability caused by uneven force on one side, thereby improving the equipment's performance. To ensure overall reliability and accuracy, and guarantee the stable positioning of the phantom during CT machine performance testing, a drive block 8 is fixedly mounted on the surface of the slider 3, and a motor 9 is fixedly mounted on the side of the phantom box 1. A bidirectional lead screw 10 is fixedly mounted on the output end of the motor 9. The bidirectional lead screw 10 is threadedly connected inside the drive block 8. The motor 9 drives the bidirectional lead screw 10 to rotate, and the drive block 8 moves on the surface of the bidirectional lead screw 10, thereby driving the slider 3 to move inside the slide rail 2. This improves the convenience and accuracy of operation. At the same time, the bidirectional lead screw 10 can provide smoother movement. A vertical plate 12 is fixedly mounted on the surface of the shelf 11, and a vertical plate 12 is fixedly mounted on the bottom of the shelf 12. A limiting block 13 is installed, and a limiting groove seat 14 is fixedly installed on the surface of the support plate 7. The limiting block 13 is slidably connected inside the limiting groove seat 14 on the surface of the support plate 7 so that the placement plate 11 can slide off the surface of the support plate 7, thereby removing the mold placed on the placement plate 11 from the mold box 1, thus facilitating personnel to use the mold to perform performance testing on the CT machine. A support frame 15 is fixedly installed on the side of the upright plate 12, and an adjusting plate 17 is slidably connected inside the support frame 15. A cylinder 19 is fixedly installed on the surface of the adjusting plate 17, and a pull plate 21 is fixedly installed on the top of the cylinder 19. A spring 20 is sleeved on the surface of the cylinder 19. The bottom of the adjusting plate 17... A positioning rod 18 is fixedly installed on the surface of the support plate 7. A through hole 16 is opened on the surface of the support plate 7. A first positioning hole 22 and a second positioning hole 23 are opened on the surface of the support plate 7. The first positioning hole 22 and the second positioning hole 23 are located at the two ends of the surface of the support plate 7, respectively. The diameters of the positioning rod 18, the first positioning hole 22 and the second positioning hole 23 are the same. The positioning rod 18 is matched with the first positioning hole 22 and the second positioning hole 23, respectively, so that the mold can be stored or slid out on the surface of the support plate 7. This makes the switching and fixing of the mold in different positions more convenient, ensures that the positioning is accurate and consistent each time, and reduces the error caused by inaccurate positioning.

[0025] Example 2

[0026] Please see Figure 1-2 and Figure 3-4A short shaft 24 is fixedly installed on the side of the shelf 11. A support rod 25 is rotatably connected to the surface of the short shaft 24. A round hole 26 is opened on the surface of the support rod 25, and a screw 27 is inserted into the round hole 26. A first screw hole 28 is opened on the side of the shelf 11, and the screw 27 is threaded into the first screw hole 28. A connecting block 29 is fixedly installed on the side of the mold box 1. A second screw hole 30 is opened on the surface of the connecting block 29. The second screw hole 30 has the same size as the first screw hole 28. When the mold slides out of the mold box 1, it is connected by the shelf 24. The support rods 25 on the side of the plate 11 are connected to the connecting blocks 29 on the side of the mold box 1, which can improve the load-bearing capacity of the mold on the plate 11 and prevent the plate 11 from bending due to excessive force during use. There are two sets of support rods 25, which are symmetrically distributed on both sides of the plate 11. The symmetrical distribution of the support rods 25 on both sides of the plate 11 can evenly support and distribute the load, avoiding deformation or tilting caused by excessive force on one side. This not only improves the overall balance, but also further enhances the structural strength of the support.

[0027] Working Principle: When performing performance testing on a CT scanner, a phantom is required. The phantom box 1 is placed on the CT scanner, and then the motor 9 is started. The output of the motor 9 drives the bidirectional lead screw 10 to rotate. The bidirectional lead screw 10 rotates inside the drive block 8, causing the drive block 8 to move on the surface of the bidirectional lead screw 10. Simultaneously, the drive block 8 drives the slider 3 to move inside the slide rail 2. When the slider 3 moves, the position between the support plate 7 and the slider 3 changes, causing the connecting rod 5 to rotate between the lower connecting seat 4 of the slider 3 and the upper connecting seat 6 at the bottom of the support plate 7. At this time, the inclined connecting rod 5 becomes vertical, allowing the support plate 7 to be lifted from inside the phantom box 1. This allows the placement plate 11 on the support plate 7 to slide smoothly without contacting the phantom box 1. When the placement plate 11 slides, the pull plate 21 is pulled up on the surface of the support frame 15, causing the pull plate 21 to move... The cylinder 19 moves the adjusting plate 17. At this time, the spring 20 on the cylinder 19 is squeezed between the adjusting plate 17 and the support 15. Simultaneously, the adjusting plate 17 drives the positioning rod 18 to disengage from the first positioning hole 22, and then pushes the upright plate 12. The upright plate 12 drives the placement plate 11 to move on the surface of the support plate 7, so that the mold on the placement plate 11 can slide out of the mold box 1, so that the CT machine can be tested. After the placement plate 11 slides out, the pull plate 21 is released. Under the elastic force of the spring 20, the positioning rod 18 can be automatically inserted into the second positioning hole 23, thereby fixing the placement plate 11. At this time, the screw 27 is unscrewed from the first screw hole 28. Then, the support rod 25 is rotated so that the round hole 26 on the support rod 25 is aligned with the connecting block 29 on the side of the mold box 1. Then, the screw 27 is passed through the round hole 26 and tightened into the second screw hole 30, thereby improving the reinforcement performance of the placement plate 11.

[0028] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
