Description

Technical Field

[0001] This utility model relates to the field of ultrasonic transducers, and in particular to an improved ultrasonic transducer. Background Technology

[0002] An ultrasonic transducer is an energy conversion device whose core function is to convert electrical energy into ultrasonic waves (high-frequency sound waves), or to convert received ultrasonic waves into electrical energy. When an alternating voltage (electrical energy) is applied to the two electrodes of a piezoelectric material, the material will periodically elongate and contract (mechanical vibration) according to the direction of the electric field, thereby driving the surrounding medium (such as water or air) to generate ultrasonic waves. When the piezoelectric material is subjected to the pressure (mechanical energy) of ultrasonic waves, its internal crystal lattice will deform, thereby generating charges on the two electrode surfaces and forming a voltage (electrical energy).

[0003] Existing ultrasonic transducers are installed in a fixed position. However, the fixed installation components prevent height adjustment during installation, resulting in poor adaptability and flexibility. This makes them prone to height deviations, leading to inaccurate installation and generally poor performance. Utility Model Content

[0004] The main objective of this invention is to provide an improved ultrasonic transducer that can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] An improved ultrasonic transducer includes an upper cover and a lower cover, which are assembled together. A ceramic wafer is provided at the connection between the upper cover and the lower cover. A positive electrode plate and a negative electrode plate are provided at the ceramic wafer. An adjustable mounting structure is provided on the lower cover, and a limiting and clamping structure is installed on the lower cover near the ceramic wafer.

[0007] Preferably, the lower cover is provided with external threads, and the adjustable mounting structure is rotatably mounted on the external threads of the lower cover.

[0008] Preferably, the upper end of the upper cover is provided with a connecting hole, and the lower end of the lower cover is fixed with a limiting sleeve, which is located below the adjustable mounting structure.

[0009] Preferably, the adjustable mounting structure includes a first mounting plate, a second mounting plate, a threaded groove, a fixed connecting block, a round hole, a connecting screw, and an arc-shaped hole. The threaded groove is disposed within the first and second mounting plates, and the threaded grooves on the first and second mounting plates seamlessly form a complete thread. The fixed connecting block is fixed at the end positions of the first and second mounting plates. The round hole is opened on the fixed connecting block. The connecting screw passes through the round hole on the fixed connecting block, and the end of the connecting screw is provided with a connecting nut. The arc-shaped hole is opened on the first and second mounting plates.

[0010] Preferably, the limiting and tightening structure includes a fixed sleeve, a first adjusting block, a second adjusting block, an adjusting screw hole, and a limiting and tightening screw. The first adjusting block and the second adjusting block are symmetrically fixed on the fixed sleeve, and the fixed sleeve is fixed on the lower cover. The adjusting screw hole is opened on the first adjusting block and the second adjusting block. The two limiting and tightening screws are respectively connected to the adjusting screw holes on the first adjusting block and the second adjusting block, and the lower end of the limiting and tightening screw abuts against the adjustable mounting structure.

[0011] Compared with the prior art, this utility model has the following beneficial effects: This improved ultrasonic transducer, by setting an external thread on the lower cover, is used in conjunction with an adjustable mounting structure, a limiting and tightening structure, and a limiting sleeve. The adjustable mounting structure is threaded onto the external thread, allowing for height adjustment, thereby changing the overall installation height of the ultrasonic transducer, improving installation flexibility and adaptability. The limiting and tightening structure provides a clamping effect on the adjustable mounting structure, ensuring that the adjustable mounting structure can be more stably set on the external thread on the lower cover, preventing the ultrasonic transducer from loosening during operation and ensuring the stability of the ultrasonic transducer. The limiting sleeve acts as a limit, preventing the adjustable mounting structure from rotating excessively and falling off. The adjustable mounting structure is equipped with a first mounting plate and a second mounting plate with threaded grooves. The threaded grooves on the two mounting plates can form a complete thread structure, which can quickly disassemble and assemble the mounting plates, and also ensure that the assembled mounting plates can be rotated and adjusted normally.

Detailed Implementation

[0017] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0018] like Figures 1-4 As shown, an improved ultrasonic transducer includes an upper cover 1 and a lower cover 2, which are assembled together. A ceramic chip 3 is provided at the connection between the upper cover 1 and the lower cover 2. A positive electrode plate 4 and a negative electrode plate 5 are provided at the ceramic chip 3. An adjustable mounting structure 6 is provided on the lower cover 2, and a limiting and abutting structure 7 is installed on the lower cover 2 near the ceramic chip 3.

[0019] The lower cover 2 is provided with an external thread 8, and the adjustable mounting structure 6 is rotatably mounted on the external thread 8 on the lower cover 2. The upper end of the upper cover 1 is provided with a connecting hole 9, and the lower end of the lower cover 2 is fixed with a limit sleeve 10, which is located below the adjustable mounting structure 6.

[0020] During the installation of the ultrasonic transducer, the adjustable mounting structure 6 is assembled onto the external thread 8 at the lower cover 2. The relative position of the adjustable mounting structure 6 is adjusted by rotation to ensure that it is properly positioned on the lower cover 2. During this process, the limiting sleeve 10 acts as a limiting stop to prevent excessive rotation and detachment of the adjustable mounting structure 6. Then, the adjustable mounting structure 6 is used in conjunction with the mounting bolts to secure the ultrasonic transducer, which is now at a suitable height. The limiting and tightening structure 7 is then operated, using its abutting part to tighten the adjustable mounting structure 6, ensuring stability during subsequent use. After the ultrasonic transducer is installed, the cable is connected to the positive electrode plate 4 and the negative electrode plate 5. Electrical energy is transmitted through the electrode plates to the ceramic wafer 3 between the lower cover 2 and the upper cover 1. The ceramic wafer 3 periodically expands and contracts according to the direction of the electric field, thereby generating ultrasonic waves to convert electrical energy into mechanical energy. The ultrasonic waves can then be used for related operations.

[0021] According to the above implementation scheme, the adjustable mounting structure 6 includes a first mounting plate 601, a second mounting plate 602, a threaded groove 603, a fixed connecting block 604, a round hole 605, a connecting screw 606, and an arc-shaped hole 607. The threaded groove 603 is provided in the first mounting plate 601 and the second mounting plate 602, and the threaded groove 603 on the first mounting plate 601 and the second mounting plate 602 seamlessly forms a complete thread. The fixed connecting block 604 is fixed at the end position of the first mounting plate 601 and the second mounting plate 602. The round hole 605 is opened on the fixed connecting block 604. The connecting screw 606 passes through the round hole 605 on the fixed connecting block 604, and the end of the connecting screw 606 is provided with a connecting nut. The arc-shaped hole 607 is opened on the first mounting plate 601 and the second mounting plate 602.

[0022] When assembling the adjustable mounting structure 6, the first mounting plate 601 and the second mounting plate 602 are directly fitted onto the external threads 8 on the lower cover 2. The threaded grooves 603 on the two mounting plates are seamlessly joined to form a complete thread that connects to the external threads 8. A connecting screw 606 is installed in the round hole 605 on the fixed connecting block 604, and a connecting nut is installed at the end of the connecting screw 606, thus completing the assembly of the adjustable mounting structure 6. When installing the ultrasonic transducer, the positions of the two mounting plates on the lower cover 2 are first adjusted using the threaded grooves 603 so that the entire adjustable mounting structure 6 is in a relatively suitable position. Then, the screw is passed through the arc-shaped hole 607 and connected to the mounting part to fix the adjustable mounting structure 6, thereby achieving the installation and fixation of the ultrasonic transducer.

[0023] According to the above implementation scheme, the limiting and tightening structure 7 includes a fixed sleeve 701, a first adjusting block 702, a second adjusting block 703, an adjusting screw hole 704, and a limiting and tightening screw 705. The first adjusting block 702 and the second adjusting block 703 are symmetrically fixed on the fixed sleeve 701, and the fixed sleeve 701 is fixed on the lower cover 2. The adjusting screw hole 704 is opened on the first adjusting block 702 and the second adjusting block 703. The two limiting and tightening screws 705 are respectively connected to the adjusting screw holes 704 on the first adjusting block 702 and the second adjusting block 703, and the lower end of the limiting and tightening screw 705 abuts against the adjustable mounting structure 6.

[0024] After the position of the adjustable mounting structure 6 is adjusted, the two limiting screws 705 can be screwed into the adjusting screw holes 704 on the first adjusting block 702 and the second adjusting block 703 on the fixed sleeve 701, respectively. Rotate the limiting screws 705 so that the ends of the limiting screws 705 abut against the first mounting plate 601 and the second mounting plate 602, forming a tight stop on the mounting plate, so that the mounting plate can withstand the external vertical force, which can ensure the stability of the mounting plate when the ultrasonic transducer is in use, avoid loosening, and ensure the stability of use.

[0025] It should be noted that by setting an external thread 8 on the lower cover 2, and using it in conjunction with the adjustable mounting structure 6, the limiting locking structure 7, and the limiting sleeve 10, the adjustable mounting structure 6 is threadedly connected to the external thread 8, allowing for height adjustment and thus changing the overall installation height of the ultrasonic transducer. This improves installation flexibility and adaptability. The limiting locking structure 7 provides a clamping effect on the adjustable mounting structure 6, ensuring that the adjustable mounting structure 6 can be more stably set on the external thread 8 on the lower cover 2, preventing the ultrasonic transducer from becoming loose during operation and ensuring the stability of the ultrasonic transducer. The limiting sleeve 10 serves as a limit to prevent the adjustable mounting structure 6 from rotating excessively and falling off. The adjustable mounting structure 6 is equipped with a first mounting plate 601 and a second mounting plate 602 with threaded grooves 603. The threaded grooves 603 on the two mounting plates can form a complete thread structure, which allows for quick disassembly and assembly of the mounting plates and ensures that the assembled mounting plates can be rotated and adjusted normally.

[0026] The foregoing describes the working principle, features, and beneficial effects of this utility model. Those skilled in the art will understand from the foregoing that it does not limit the utility model. The embodiments and description above illustrate the basic principles and features of this utility model. Various changes and improvements can be made to this utility model while remaining consistent with its concept, and all such improvements should fall within the scope of protection claimed by this utility model.
