[0023] According to one embodiment of the present invention, in conjunction with Figure 1 The diagram illustrates an electrical safety test protector for medical devices, comprising a test machine 1. A test platform 2 is fixedly connected to the top of the test machine 1. An anti-displacement automatic shut-off assembly 3 is disposed on the top of the test machine 1. The anti-displacement automatic shut-off assembly 3 includes a support rod 31, one end of which is fixedly connected to the side of the test machine 1. A motor 32 is fixedly connected to the side of the support rod 31. A bidirectional lead screw 34 is fixedly connected to the output shaft of the motor 32. A threaded sleeve 35 is threadedly connected to the circumferential surface of the bidirectional lead screw 34. A limit rod 36 is fixedly connected to the side of the motor 32. The end of the limit rod 36 away from the motor 32 passes through the side of the threaded sleeve 35. A fixing plate 37 is fixedly connected to the side of the threaded sleeve 35. A pressing rod 38 is fixedly connected to the side of the fixing plate 37. A switch 315 is provided on the side of the testing machine 1. A crossbar 39 is fixedly connected to the side of the testing machine 1. A pressure chamber 310 is fixedly connected to one end of the crossbar 39. A push rod 311 passes through one end of the pressure chamber 310. A push rod 314 passes through the end of the pressure chamber 310 away from the push rod 311. A triangular block 312 is fixedly connected to one end of the push rod 311.

[0024] Two threaded sleeves 35 and fixing plates 37 are provided and are symmetrical to each other along the vertical central axis of the bidirectional lead screw 34. The switch 315 is located on the displacement trajectory of the push rod 314, and the triangular block 312 is located on the displacement trajectory of the compression rod 38. The two fixing plates 37 are provided to clamp the two sides of the medical device to be tested, prevent the device from shaking or shifting during the test, and prevent the test results from being affected.

[0025] A spring 313 is fixedly connected to the circumferential surface of the push rod 311. The end of the spring 313 away from the push rod 311 is fixedly connected to the side of the pressure chamber 310. The design of the spring 313 is conducive to the automatic reset of the push rod 311 when it is not compressed.

[0026] The test bench 2 is located on the displacement trajectory of the fixed plate 37. The side of the test machine 1 is equipped with a touch screen 316, and the top of the motor 32 is equipped with a button. The design of the touch screen 316 makes it convenient to operate the entire test machine 1, allowing users to perform tests more intuitively.

[0027] The side of the testing machine 1 is provided with a test protection component 4, which includes a support plate 41. One side of the support plate 41 is fixedly connected to the side of the testing machine 1. A protection plate 42 is slidably connected to the top of the support plate 41. A short plate 44 is fixedly connected to the inner wall of the protection plate 42. A long rod 43 is fixedly connected to the side of the fixed plate 37. During the test, the protection plate 42 is used to block the left and right sides of the test platform 2 to reduce external interference during the test.

[0028] The short plate 44 is located on the displacement trajectory of the long rod 43, and the protective plate 42 is located on the side of the test bench 2. There are two protective plates 42, which are symmetrical to each other along the vertical central axis of the test machine 1. This design is beneficial to move the short plate 44 and the protective plate 42 when the long rod 43 moves.

[0029] An L-shaped rod 45 is fixedly connected to the side of the support plate 41, and a second spring 46 is fixedly connected to the side of the L-shaped rod 45. The end of the second spring 46 away from the L-shaped rod 45 is fixedly connected to the side of the protection plate 42. An insertion port 5 is provided on the side of the testing machine 1. The design of the second spring 46 is conducive to automatic reset when the protection plate 42 is not moved.

[0030] In this embodiment, pressing switch 315 starts the entire testing machine 1 for testing. The medical device to be tested is placed on the testing platform 2, and the values ​​are adjusted on the touch screen 316 for testing. The connector 5 can be used to connect wires and other lines to improve testing efficiency. To prevent displacement or shaking of the medical device during testing, motor 32 is started and rotated forward. The forward rotation of motor 32 drives the bidirectional lead screw 34 to rotate forward, which in turn drives the threaded sleeve 35 and the fixing plate 37 to move relative to each other, causing the two fixing plates 37 to move in the same direction. The testing platform 2 is located on the movement trajectory of the fixing plates 37. When the two fixing plates... When the two fixed plates 37 move relative to each other, they clamp the two sides of the medical device placed on the test platform 2, temporarily fixing its position to prevent displacement and shaking during testing, which would affect the test results. When the two fixed plates 37 move in the same direction, one of the fixed plates 37 will also drive the compression rod 38 to move. The triangular block 312 is located on the movement trajectory of the compression rod 38. When the compression rod 38 moves, it will compress the triangular block 312 and the push rod 311. The push rod 311 passes through and slides on the side of the pressure chamber 310. When the triangular block 312 and the push rod 311 are compressed, they will slide into the pressure chamber 310, pushing the pressure chamber 310. The movement of gas inside chamber 10 pushes out push rod 314 at the other end of pressure chamber 310. Switch 315 is located on the movement trajectory of push rod 314. When push rod 314 is pushed out, it triggers switch 315, thus automatically starting test machine 1. When the two fixing plates 37 move in the same direction, they clamp and fix the two sides of the medical device, indicating that testing is in preparation. At this time, switch 315 is automatically opened, automatically starting test machine 1 for convenient use. When the test is completed, motor 32 drives bidirectional lead screw 34 to reverse, causing the two fixing plates 37 to move in opposite directions, preventing switch 315 from being further compressed. Therefore, the test... The test machine 1 will shut down automatically, thus achieving automatic shutdown of the test machine 1. This system reduces the need for manual operation by automatically starting and stopping the test machine 1. When preparing for the test, switch 315 will be automatically activated and start the test machine 1. After the test is completed, the test machine 1 will automatically shut down. This automated control reduces the possibility of human error and improves operational efficiency. Through the cooperation of motor 32 and bidirectional lead screw 34, the fixing plate 37 can effectively clamp the medical device on the test table 2 to prevent it from shifting or shaking during the test, ensuring that the medical device will not shift or shake during the test. The protector ensures the accuracy of the test data.

[0031] When the two fixed plates 37 move relative to each other in the same direction, they will cause the long rod 43 to move. The short plate 44 is located on the movement trajectory of the long rod 43. When the long rod 43 moves, it will cause the short plate 44 to move. The movement of the short plate 44 will cause the protective plate 42 to move, causing the protective plate 42 to slide on the top of the support plate 41. This will cause the two protective plates 42 to move closer to the sides of the test platform 2, blocking the left and right sides of the test platform 2 and preventing external interference to the medical equipment during testing. When the fixed plates 37 move in the opposite direction, they will cause the long rod 43 to move in the opposite direction, and will not cause the short plate 44 and the protective plate 42 to move closer to the test platform. When the test bench 2 moves to one side, the protection plate 42 can be automatically reset by the second spring 46, making it convenient to perform protection again next time. By moving the protection plate 42 left and right, it can effectively block both sides of the test bench 2 to prevent external interference from entering the test area. This can ensure that the electrical safety test is not affected by external factors, and guarantee the accuracy and reliability of the test results. The protection plate 42 can be automatically reset by the second spring 46. When the fixed plate 37 moves in the opposite direction, the protection plate 42 will automatically return to its original position. This design improves the automation level of the equipment, reduces the need for manual operation, improves the ease of use, and saves time and labor costs.

[0032] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
