Description

Technical Field

[0001] This utility model relates to the field of ultrasonic testing technology, and in particular to a non-metallic ultrasonic testing instrument. Background Technology

[0002] The non-metallic ultrasonic instrument integrates ultrasonic wave transmission, dual-channel synchronous reception, high-speed digital signal acquisition, automatic acoustic parameter detection, data analysis and processing, real-time result display, data storage and output. It can perform non-destructive testing of non-metallic materials and components such as concrete and plastics using ultrasonic waves. The non-metallic ultrasonic instrument can also perform integrity testing on concrete pile foundations. It is a dual-channel, high-resolution, digital instrument with functions such as time-division sampling, overlay, filtering, signal enhancement, noise suppression, and real-time on-site calculation, displaying measured waveforms and test results.

[0003] Current non-metallic ultrasonic testing instruments mainly consist of a main unit, signal lines, and transducers. The transducers are connected to the main unit via the signal lines. During testing, a coupling agent is first applied to the target location, and then the transducer is held and placed against the coupling agent to perform the test. However, for some clamp-type tests, two hands are needed to hold two transducers and place them against both sides of the target object. This means that the main unit cannot be operated free of hands, so at least two people are required to complete the test, making it neither simple nor convenient to use. Therefore, to address the above shortcomings, this utility model proposes a non-metallic ultrasonic testing instrument. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a non-metallic ultrasonic testing instrument.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a non-metallic ultrasonic detector, comprising a main unit, two signal lines, two transducers, and a handle. The two transducers are connected to the main unit interface via the two signal lines. An installation assembly is fixed to the lower surface of the main unit. An end shell is fixed to one end of the handle, and a horizontal plate is fixed to the other side of the end shell. The horizontal plate has a hollow interior, and square openings are provided on both sides of the horizontal plate. Two sliding plates are slidably connected through the two square openings. A driving assembly for moving the two sliding plates is provided in the middle of the horizontal plate and inside the end shell.

[0006] Furthermore, the mounting assembly includes a support base fixed to the lower surface of the host, and the lower surface of the support base is designed with an arc surface. Straps are fixed on both sides of the lower surface of the support base, and the surface of the straps is provided with Velcro.

[0007] Furthermore, two support plates are fixed in the middle of the horizontal plate.

The output shaft of the miniature geared motor extends into the horizontal plate and is fixed with a drive bevel gear. A driven bevel gear is fixed at the adjacent ends of the two lead screws. Both driven bevel gears mesh with the drive bevel gear.

[0008] Furthermore, the handle surface is provided with a control button for controlling the micro geared motor.

[0009] Furthermore, the support assembly includes a curved rod fixed to the surface of the skateboard, a sleeve is slidably sleeved on the surface of the curved rod away from the skateboard, and a clamp is fixed to the outer wall of the sleeve, and the transducer is fixed inside the clamp.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1-4 As shown, a non-metallic ultrasonic detector is disclosed, comprising a main unit 1, two signal lines 2, two transducers 3, and a handle 5. The two transducers 3 are connected to the main unit 1 via the two signal lines 2. An installation component 4 is fixed to the lower surface of the main unit 1. An end shell 6 is fixed to one end of the handle 5, and a horizontal plate 7 is fixed to the other side of the end shell 6. The horizontal plate 7 has a hollow interior, and square openings 71 are provided on both sides of the horizontal plate 7. Two sliding plates 72 are slidably connected through the two square openings 71. A drive component 8 for moving the two sliding plates 72 is provided in the middle of the horizontal plate 7 and inside the end shell 6. Support components 9 for mounting the transducers 3 are fixed to the surfaces of the two sliding plates 72.

[0023] The mounting component 4 includes a support base 41 fixed to the lower surface of the main unit 1. The lower surface of the support base 41 is curved. Straps 42 are fixed on both sides of the lower surface of the support base 41, and the surface of the straps 42 is provided with Velcro.

[0024] When using the main unit 1, the arc groove on the lower surface of the support base 41 can be fitted onto the arm, and then the main unit 1 can be tightly secured to the arm using the strap 42.

[0025] Two support plates 73 are fixed in the middle of the horizontal plate 7. The drive assembly 8 includes a micro geared motor 81 fixed inside the end shell 6 and two lead screws 83 passing through the two support plates 73. The two lead screws 83 are rotatably connected to the two support plates 73 through bearings. The two lead screws 83 pass through the two slide plates 72 and are threadedly connected to the slide plates 72. The output shaft of the micro geared motor 81 extends into the interior of the horizontal plate 7 and is fixed with a drive bevel gear 82. The adjacent ends of the two lead screws 83 are fixed with driven bevel gears 84. The two driven bevel gears 84 mesh with the drive bevel gear 82.

[0026] When the micro gear motor 81 drives the active bevel gear 82 to rotate, the active bevel gear 82 will drive the two driven bevel gears 84 to rotate synchronously, thereby realizing the synchronous rotation of the two lead screws 83. The two lead screws 83 will drive the slide plate 72 to move along the square opening 71. Therefore, by controlling the micro gear motor 81 to rotate forward or reverse, the slide plate 72 can be moved out of or into the horizontal plate 7.

[0027] The surface of handle 5 is equipped with a control button for controlling the micro geared motor 81.

[0028] When holding the handle 5, the micro geared motor 81 can be controlled to rotate forward or backward via the control button.

[0029] The support assembly 9 includes a bent rod 91 fixed to the surface of the slide plate 72. A sleeve 92 is slidably sleeved on the surface of the bent rod 91 away from the slide plate 72, and a clamp 94 is fixed to the outer wall of the sleeve 92. The transducer 3 is fixed inside the clamp 94.

[0030] The transducer 3 can be fixed by the clamp 94. When both slide plates 72 move inward to the horizontal plate 7, they can drive the two support components 9 to move closer together, thereby driving the two transducers 3 to move closer together. When the two slide plates 72 move outward to the horizontal plate 7, they can drive the two transducers 3 to separate.

[0031] A spring 93 is fixedly connected to the inner wall of the sleeve 92 and the end of the bent rod 91. By setting the spring 93 for buffering, it can prevent the two transducers 3 from making hard contact with the object under test when they come close together, thereby preventing the transducers 3 from being crushed.

[0032] Working principle: First, fix the main unit 1 to the arm using the mounting component 4. Then, connect the transducer 3 to the main unit 1 via the signal line 2. Apply coupling agent to the target object. Next, hold the handle 5 with the arm that is fixing the main unit 1 and place the two transducers 3 on both sides of the object. Then, start the micro geared motor 81 by controlling the control button, which drives the two support components 9 to move closer together, so that the two transducers 3 are in contact with the surface of the object. Then, the other hand can operate the main unit 1 to perform the test. The operation method and principle of the main unit 1 are the same as those of the existing technology.

[0033] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
