Description

Technical Field

[0001] This utility model belongs to the field of high-frequency, high-bandwidth elastic wave technology, specifically, it relates to a high-frequency, high-bandwidth elastic wave device. Background Technology

[0002] In today's highly technological era, numerous cutting-edge fields are increasingly reliant on elastic wave technology, and the performance requirements for elastic wave devices have reached unprecedented heights. From microscopic materials science research and precise biomedical diagnostics to macroscopic aerospace engineering, geological resource exploration, and marine surveying, elastic wave devices play an indispensable role. Furthermore, elastic wave transducers have emerged to address these diverse needs. As a key device capable of converting elastic waves into electrical signals, the elastic wave transducer's applications span multiple important fields, including nondestructive testing, geological exploration, ultrasonic medical imaging, materials science research, and underwater acoustic detection.

[0003] However, when installing existing elastic wave transducers, the electrode plates are usually moved to a certain position on the main body and then fixed with fixing bolts. However, when fixing the electrode plates, the electrode plates often wobble, so the staff needs to constantly adjust the position of the electrode plates to ensure that the fixing bolts can fix the electrode plates in place.

[0004] In view of this, this utility model is proposed. Utility Model Content

[0005] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows:

[0006] A high-frequency, wide-bandwidth elastic wave device includes an elastic wave transducer and an electrode sheet. The elastic wave transducer has multiple slots arranged in a circular pattern, and each slot has a wedge-shaped insertion plate inside. The electrode sheet is disposed on the outer wall of the elastic wave transducer, and the inner ring of the electrode sheet has multiple insertion slots arranged in a circular pattern.

[0007] In a preferred embodiment of this utility model, two symmetrical inclined slide grooves are provided on the opposite side walls of each slot cavity, and a guide slider is slidably arranged between each pair of inclined slide grooves. Each pair of guide sliders is symmetrical to each other, and a wedge-shaped plug plate is connected to one side of each pair of guide sliders.

[0008] In a preferred embodiment of the present invention, each of the slots has a movable slide groove, each of the movable slide grooves has a movable slider slidably disposed thereon, and each movable slider has a rectangular tube disposed at one end away from the movable slide groove.

[0009] In a preferred embodiment of the present invention, each of the rectangular tubes has a sliding plate slidably disposed therein, and each of the sliding plates has a rectangular insertion rod disposed at one end near the wedge-shaped insertion plate, and each rectangular insertion rod movably passes through the rectangular tube.

[0010] In a preferred embodiment of this utility model, a return spring is fixedly connected to one end of each movable plate away from the rectangular plug rod, and the other end of each return spring is respectively disposed on the inner wall of the rectangular tube.

[0011] In a preferred embodiment of this utility model, each of the said plug slots is respectively matched with the wedge-shaped plug plate.

[0012] Compared with the prior art, the present invention has the following advantages:

[0013] This invention allows the wedge-shaped insertion plate to enter the slot cavity when the electrode plate moves to a certain position, with the outer wall of the wedge-shaped insertion plate positioned on the inner ring of the electrode plate. As the motor plate continues to move, the wedge-shaped insertion plate contacts the insertion slot and is ejected into the insertion slot with the assistance of the return spring and the rectangular insertion rod. This ensures that the electrode plate is positioned during bolt installation and prevents it from shaking or falling off.

[0014] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings. Attached Figure Description

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0023] like Figures 1 to 5 As shown, a high-frequency, high-bandwidth elastic wave device includes an elastic wave transducer 1 and an electrode plate 3. The elastic wave transducer 1 has multiple circumferentially distributed slots 2, and each slot 2 has a wedge-shaped insertion plate 5 inside its cavity. The electrode plate 3 is disposed on the outer wall of the elastic wave transducer 1, and the inner ring of the electrode plate 3 has multiple circumferentially distributed insertion slots 4. When the electrode plate 3 moves to a certain position, it can drive the wedge-shaped insertion plate 5 into the cavity of the slot 2, and make the outer wall of the wedge-shaped insertion plate 5 lie on the inner ring of the electrode plate 3. When the electrode plate 3 continues to move, it can make the wedge-shaped insertion plate 5 contact the insertion slot 4, and with the assistance of the return spring 11 and the rectangular insertion rod 9, the wedge-shaped insertion plate 5 can be ejected into the insertion slot 4, thereby ensuring that the electrode plate 3 can be positioned when bolted or installed, preventing it from shaking and falling off.

[0024] In a specific embodiment, two symmetrical inclined slide grooves 12 are formed on the opposite side walls of the inner cavity of each slot 2. A guide slider 13 is slidably arranged between each pair of inclined slide grooves 12. Each pair of guide sliders 13 is symmetrical with each other, and a wedge-shaped plug plate 5 is connected to one of the opposite sides of each pair of guide sliders 13. In this configuration, the specific installation position of the wedge-shaped plug plate 5 is determined to ensure that the wedge-shaped plug plate 5 can move obliquely and vertically upward.

[0025] Furthermore, each slot 2 has a movable slide groove 6 inside its cavity, and each movable slide groove 6 has a movable slider 7 slidably mounted inside its cavity. Each movable slider 7 has a rectangular tube 8 mounted at one end away from the movable slide groove 6. In this configuration, the installation position of the rectangular tube 8 is determined, ensuring that the rectangular tube 8 can move horizontally.

[0026] Furthermore, a movable plate 10 is slidably disposed within the inner cavity of each rectangular tube 8, and a rectangular insertion rod 9 is disposed at one end of each movable plate 10 near the wedge-shaped insertion plate 5, with each rectangular insertion rod 9 movably penetrating through the rectangular tube 8. In this arrangement, the installation position of the rectangular insertion rod 9 is determined to ensure that the rectangular insertion rod 9 can move horizontally.

[0027] Furthermore, each movable plate 10 has a return spring 11 fixedly connected to one end away from the rectangular plug rod 9, and the other end of each return spring 11 is respectively disposed on the inner wall of the rectangular tube 8. In this configuration, the installation position of the return spring 11 is determined to ensure that the movable plate 10 can move horizontally under the elastic force of the return spring 11.

[0028] Furthermore, each insertion slot 4 is respectively matched with the wedge-shaped insertion plate 5. In this configuration, the relationship between the insertion slot 4 and the wedge-shaped insertion plate 5 is defined.

[0029] The implementation principle of a high-frequency, large-bandwidth elastic wave device in this embodiment is as follows:

[0030] First, the operator moves the electrode plate 3 upwards from the bottom of the elastic wave transducer 1 until it moves from the outer wall to below the wedge-shaped insertion plate 5. At this point, the operator adjusts the position of the electrode plate 3 so that the insertion slot 4 is positioned directly below the wedge-shaped insertion plate 5. The operator continues to move the electrode plate 3, causing it to move the wedge-shaped insertion plate 5 into the slot 2 with the assistance of the inclined slide 12 and the guide slider 13. Because a rectangular insertion rod 9 is provided at one end of the wedge-shaped insertion plate 5 inside the slot 2, and this rectangular insertion rod 9 is inserted into the rectangular cylinder 8, when the wedge-shaped insertion plate 5 moves into the slot 2, the rectangular insertion rod 9 moves into the rectangular cylinder 8, thus allowing the rectangular insertion rod 9 to push the plate forward. The moving plate 10 moves, compressing the return spring 11 until the electrode plate 3 moves to a certain position. At this point, the electrode plate 3 will contact the outer wall of the elastic wave transducer 1, and the wedge-shaped insertion plate 5 will be located in the inner ring of the electrode plate 3. Continuing to move the electrode plate 3 will allow it to make close contact with the elastic wave transducer 1, and at the same time, allow the wedge-shaped insertion plate 5 to be located in the inner ring of the electrode plate 3. Because the wedge-shaped insertion plate 5 is subjected to the elastic force of the return spring 11 and its own movement trajectory is inclined downward, when the electrode plate 3 is in close contact with the outer wall of the elastic wave transducer 1, the wedge-shaped insertion plate 5 can be inserted into the insertion slot 4 opened at the electrode plate 3, thereby performing further positioning and ensuring that the electrode plate 3 will not fall downward when bolts or other installations are performed.
