Description

Technical Field

[0001] This utility model relates to the field of ultrasonic equipment technology, and in particular to an ultrasonic equipment performance calibration and testing device. Background Technology

[0002] Ultrasonic equipment performance calibration and testing is a crucial step in ensuring the accurate operation of the equipment. It covers many aspects, such as testing parameters like the frequency, sensitivity, and resolution of the ultrasonic probe, and evaluating performance indicators like image clarity and uniformity. By using professional testing instruments and standard test blocks and strictly following standardized procedures, equipment deviations can be detected and calibrated in a timely manner, ensuring accurate and reliable diagnostic results and providing solid technical support for fields such as medical and industrial testing.

[0003] In existing technologies, the target is fixed, making it difficult to flexibly adapt to different frequencies and types of ultrasonic probes. The test block often needs to be replaced during calibration, which is complicated and has limited applicability. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies, such as the complexity of target fixation and test block replacement, and the limited applicability, by proposing an ultrasonic equipment performance calibration and testing device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An ultrasonic equipment performance calibration and testing device, comprising:

[0007] A base, the top of which is provided with a test plate, and two first sliding frames and two second sliding frames are slidably arranged inside the base. The two first sliding frames are arranged longitudinally, and the two second sliding frames are arranged laterally and are cross-shaped with the first sliding frames. Four sliders are correspondingly arranged between adjacent first sliding frames and second sliding frames, and a first magnetic plate is fixedly installed on the top of each slider.

[0008] The test plate has a second magnetic plate fixedly installed at the four bottom corners, which is attracted to the first magnetic plate;

[0009] The relative positions of the four first magnetic plates can be adjusted by moving the first sliding frame and the second sliding frame to accommodate test plates of different sizes.

[0010] In one possible design, scale lines are provided on the top surface of both the first sliding frame and the second sliding frame.

[0011] In one possible design, a rotating shaft is mounted on the top of the first magnetic plate via a rotating seat. An L-shaped clamping plate and a torsion spring are rotatably sleeved on the rotating shaft, with both ends of the torsion spring fixedly connected to the L-shaped clamping plate and the rotating seat, respectively. An arc-shaped clearance groove is formed at the bottom of the second magnetic plate, and an arc-shaped retaining groove is formed on the outer side. When the second magnetic plate is attracted to the first magnetic plate, the L-shaped clamping plate is engaged into the arc-shaped retaining groove under the action of the torsion spring, forming a locking and fixing.

[0012] In one possible design, a temperature sensor and a humidity sensor are also fixedly mounted on the top of the base.

[0013] In one possible design, a performance calibration and testing body is fixedly mounted on the top of the base. The performance calibration and testing body includes a bracket, a three-dimensional moving platform mounted on the top of the bracket, and an ultrasonic probe fixed to the Z-axis of the three-dimensional moving platform.

[0014] In one possible design, a control box is provided on one side of the performance calibration and testing body. The control box is electrically connected to a temperature sensor and a humidity sensor to receive temperature and humidity data and perform compensation processing.

[0015] In this application, when replacing the test plate at the top of the base, lifting the test plate upwards releases the second magnetic plate from the first magnetic plate. Simultaneously, as the second magnetic plate moves upwards, it pushes the L-shaped locking plate to flip, thus releasing the L-shaped locking plate from the second magnetic plate. Then, according to the size of the replacement test plate, the two first sliding frames and two second sliding frames are pulled to adjust the distance between the two second sliding frames and the two first sliding frames, thereby adjusting the distance between the four first magnetic plates. The movement distance is determined by the scale lines on the top of the first and second sliding frames to achieve the required distance for the corresponding model of test plate. When installing the new test plate, the four second magnetic plates at the bottom of the test plate are magnetically attracted by the first magnetic plate. When the second magnetic plate and the first magnetic plate are magnetically attracted and fixed, the arc-shaped clearance groove at the bottom of the second magnetic plate causes the four L-shaped clamping plates to flip on the rotating shaft. At the same time, the L-shaped clamping plates drive the torsion springs on both sides to generate torque. When the second magnetic plate descends, the L-shaped clamping plates move into the arc-shaped clamping grooves. The torsion springs reset and drive the L-shaped clamping plates to embed into the arc-shaped clamping grooves to form a locking and fixing, thereby completing the further fixing of the second magnetic plate. Then, the performance calibration and testing body is adjusted through the control box. According to the testing needs, the probe of the performance calibration and testing body is adjusted to move horizontally and vertically to align the top of the test plate. During the testing process, the temperature sensor and humidity sensor respectively monitor the temperature and humidity to collect data and transmit it to the processor for data compensation.

[0016] Beneficial effects: The ultrasonic equipment performance calibration and testing device described in this utility model is easy to operate when changing test plates. Simply lift it upwards to release the adsorption between the second magnetic plate and the first magnetic plate, and at the same time release the jamming. It can also adjust the distance between the two first sliding frames and the two second sliding frames according to the size of the new test plate. The moving distance can be accurately determined with the help of scale lines, so that the spacing of the four first magnetic plates is adapted to meet the installation requirements of different test plates and improve the versatility of the equipment.

[0017] In this utility model, the ultrasonic equipment performance calibration and testing device uses a dual fixing method of magnetic attraction and snap-fit ​​to ensure the test plate is installed stably. After the initial magnetic attraction, the arc-shaped clearance groove pushes the L-shaped card plate to flip, which drives the torsion spring to generate torque. After the L-shaped card plate is embedded into the arc-shaped card groove to form a snap-fit, it is further reinforced. In addition, the movement of the main probe of the performance calibration and testing device can be adjusted by the control box to accurately align with the top of the test plate. With the help of temperature and humidity sensors, temperature and humidity monitoring and data compensation are performed to ensure the accuracy of the test.

[0018] In this invention, the equipment is easy to operate when replacing parts and can be accurately adapted to different models. The dual fixing method ensures the stable installation of parts, and the probe position can be precisely adjusted. With the help of data monitoring and compensation, the equipment's versatility and detection accuracy are effectively improved, providing reliable support for the performance calibration and testing of ultrasonic equipment.
