Description

Technical Field

[0001] This utility model relates to the field of shielding device technology; more specifically, it relates to an electromagnetic interference shielding device for ultrasonic diagnostic instruments. Background Technology

[0002] Electromagnetic interference (EMI) shielding devices in acoustic diagnostic instruments are designed to ensure normal operation in strong electromagnetic environments, reduce the impact of EMI on image quality and equipment performance, and thus ensure the accuracy of diagnostic results. These shielding devices are typically implemented using metal casings or shielding materials that can block or absorb electromagnetic waves.

[0003] Currently, existing electromagnetic interference shielding devices for ultrasonic diagnostic instruments are typically designed with a fixed height, limiting their applicability to only one type of ultrasonic diagnostic instrument. This restricts their scope of application and reduces the equipment's usability. Furthermore, uneven ground conditions may occur during use, causing the bottom of the device to fail to make proper contact with the ground. This results in a significant amount of electromagnetic interference remaining on the device's surface and failing to be properly grounded and discharged, affecting the shielding effect and further reducing the device's practicality. Therefore, there is an urgent need for electromagnetic interference shielding devices for ultrasonic diagnostic instruments to address these issues. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides an electromagnetic interference shielding device for an ultrasound diagnostic instrument to solve the problems existing in the background art.

[0005] This utility model provides the following technical solution: an electromagnetic interference shielding device for an ultrasonic diagnostic instrument, comprising: The base plate has a lifting structure inside, and a groove is opened in the middle of the bottom ends on both sides of the base plate. The bottom ends on both sides of the base plate are equipped with an adjustment structure, and the adjustment structure is provided in four sets. The lifting structure includes a movable groove and a first bevel gear, and the movable groove is opened inside the base plate; The adjustment structure includes a conductive plate, and one side of the outer surface of the conductive plate is fixedly connected to the base plate.

[0006] Preferably, the lifting structure further includes a rotating rod, which is inserted into the bottom of one side of the movable groove. One end of the rotating rod is fixedly connected to a first bevel gear inside the movable groove. A second bevel gear meshing with the first bevel gear is provided on one side of the movable groove. A lead screw is fixedly connected inside the second bevel gear, and an extension plate is threaded onto the outer surface of the lead screw. A limiting groove is formed on the side of the extension plate away from the lead screw. A limiting rod is fixedly connected to the other side of the movable groove, and a limiting circular plate is fixedly connected to the top of the limiting rod inside the limiting groove. This design allows for adjustment of the extension length of the extension plate.

[0007] Preferably, a baffle plate is fixedly connected inside the movable groove above the first bevel gear, and the width of the baffle plate is the same as the width of the movable groove. This design can protect the first bevel gear and prevent the extension plate from contacting the first bevel gear.

[0008] Preferably, the internal dimensions of the limiting groove are adapted to the external dimensions of the limiting circular plate, which allows the extension plate to move more smoothly.

[0009] Preferably, the adjustment structure further includes a movable groove, which is located at the bottom of the conductive plate. The conductive plate is internally threaded with a threaded rod, and the bottom of the threaded rod is fixedly connected to a contact plate. This design allows for control of the movement distance of the contact plate.

[0010] Preferably, the external dimensions of the contact plate are adapted to the internal dimensions of the moving groove, which makes the movement of the contact plate more stable.

[0011] The technical effects and advantages of this utility model are as follows: By rotating the rotating rod, the first bevel gear and the second bevel gear can be driven to rotate, which in turn causes the lead screw to rotate. At this time, the extension plate will move upward along the outer surface of the lead screw until the extension plate moves to a suitable position, and then the rotating rod is stopped. This design allows the extension height of the extension plate to be adjusted, so that more space can be left inside the base plate. At this time, the extension height of the extension plate can be adjusted according to the different sizes of ultrasound diagnostic instruments, which enhances the applicability and improves the applicability of the equipment to a certain extent. By rotating the threaded rod in sequence, the contact plate can be moved downwards until it contacts the ground. Once the threaded rod is stopped, the rotation of the threaded rod can be stopped. This design allows the base plate to remain stable by adjusting the height of the four sets of contact plates. The full contact between the contact plates and the ground allows electromagnetic waves to be introduced from the surface of the base plate into the ground, providing good guidance and maintaining a stable shielding effect. This improves the practicality of the equipment to a certain extent. Moreover, its overall structure is simple and reasonable, highly practical, and easy to promote and apply.

[0017] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The shielding device involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0018] Example 1 like Figures 1-3 As shown in the figure, this embodiment proposes an electromagnetic interference shielding device for an ultrasound diagnostic instrument, including: The base plate 1 has a lifting structure 2 inside, and a wire groove 3 is opened in the middle of the bottom of both sides of the base plate 1. An adjustment structure 4 is set at the bottom of both sides of the base plate 1, and there are four sets of adjustment structures 4. This design allows the wires of the ultrasound diagnostic instrument to pass through the inside of the wire groove 3 under the action of the wire groove 3. The lifting structure 2 includes a movable groove 21 and a first bevel gear 23. The movable groove 21 is located inside the base plate 1. The lifting structure 2 also includes a rotating rod 22, which is inserted into the bottom of one side inside the movable groove 21. One end of the rotating rod 22 is fixedly connected to the first bevel gear 23 inside the movable groove 21. A second bevel gear 24 that meshes with the first bevel gear 23 is provided on one side inside the movable groove 21. A lead screw 25 is fixedly connected inside the second bevel gear 24. An extension plate 26 is threadedly connected to the outer surface of the lead screw 25. A limiting groove 27 is provided on the side of the extension plate 26 away from the lead screw 25. A limiting rod 28 is fixedly connected to the other side inside the movable groove 21. A limiting circular plate 29 is fixedly connected to the top of the limiting rod 28 inside the limiting groove 27. Both top ends of the outer surface of the extension plate 26 are made of transparent glass. This transparent glass design allows staff to easily observe the situation on the ultrasound diagnostic instrument when the device is covered on the outer surface of the ultrasound diagnostic instrument. Inside the movable slot 21, above the first bevel gear 23, a baffle plate is fixedly connected, and the width of the baffle plate is the same as the width of the movable slot 21. This design can limit the movement distance of the extension plate 26, preventing the extension plate 26 from moving too low and touching the first bevel gear 23, thus affecting the rotation of the first bevel gear 23. The internal dimensions of the limiting groove 27 are matched with the external dimensions of the limiting circular plate 29. This design allows the extension plate 26 to move more smoothly and also limits the extension plate 26 to prevent it from detaching from the movable groove 21.

[0019] Example 2 like Figure 4 As shown, based on the same concept as the above embodiments, this embodiment also proposes: The adjustment structure 4 includes a conductive plate 41, and one side of the outer surface of the conductive plate 41 is fixedly connected to the base plate 1. The adjustment structure 4 also includes a moving groove 42, which is opened at the bottom of the inner part of the conductive plate 41. A threaded rod 43 is threadedly connected to the inside of the conductive plate 41, and a contact plate 44 is fixedly connected to the bottom end of the threaded rod 43. Both the contact plate 44 and the conductive plate 41 are made of metal conductive material. This design can control the moving distance of the contact plate 44. When the contact plate 44 contacts the ground, under the action of the conductive material of the conductive plate 41 and the contact plate 44, the electromagnetic waves intercepted by the outer surface of the base plate 1 and the extension plate 26 can flow into the ground from the surface of the contact plate 44, achieving a good shielding effect. The external dimensions of the contact plate 44 are adapted to the internal dimensions of the moving groove 42, which makes the movement of the contact plate 44 more stable.

[0020] Working principle: When using the equipment, first rotate the rotating rod 22, which will drive the first bevel gear 23 to rotate. Since the second bevel gear 24 meshes with the first bevel gear 23, it will drive the second bevel gear 24 to rotate as well, and cause the lead screw 25 to rotate. At this time, the extension plate 26 will move upward along the outer surface of the lead screw 25 until the extension plate 26 moves to the appropriate position. Then stop rotating the rotating rod 22. At this time, two workers will lift the base plate 1 and place it on the outside of the ultrasound diagnostic instrument. This design can adjust the extension height of the extension plate 26 to make it suitable for ultrasound diagnostic instruments of various types and sizes. After the equipment is used, simply lift it again, remove it, and reverse the above operation to make most of the extension plate 26 retract into the interior of the movable groove 21, reducing the overall space occupied by the base plate 1 and improving the overall aesthetics of the equipment. When using the equipment, the threaded rod 43 can be rotated sequentially, which can drive the contact plate 44 to move downwards until all four sets of contact plates 44 are in contact with the ground. Then, stop rotating the threaded rod 43. At this time, due to the conductive material of the contact plate 44 and the conductive plate 41, the electromagnetic waves intercepted by the outer surface of the base plate 1 and the extension plate 26 can be poured into the bottom surface of the contact plate 44 and introduced into the ground through the contact plate 44 for discharge. At the same time, the four sets of contact plates 44 can be matched together to keep the base plate 1 stable when it is fitted on the outer surface of the ultrasound diagnostic instrument, making it convenient for staff to observe the data displayed on the ultrasound diagnostic instrument through the transparent glass of the extension plate 26. The above is the complete working principle of this utility model.
