Description

Technical Field

[0001] This utility model relates to the field of ultrasonic transducer technology, and in particular to a high-density area array transducer. Background Technology

[0002] In terms of background technology, with the development of science and technology, the demand for high-density area array transducers is increasing in many fields. In the field of medical ultrasound imaging, in order to obtain clearer and higher-resolution images of internal human tissue structures, transducers need to have a denser array element distribution to achieve precise beam control and signal reception. In industrial non-destructive testing, in order to accurately detect minute defects inside materials, transducers are also required to have higher detection accuracy and sensitivity. High-density area array transducers can better meet these needs.

[0003] However, existing high-density array transducers have some problems in practical use: 1. Their installation structure is not stable and flexible enough, making it difficult to adapt to different installation environments and usage requirements; 2. There are insufficient protection measures for components such as cables, which are easily damaged by wear, pulling, etc., thus affecting the normal operation of the entire transducer. Utility Model Content

[0004] The main objective of this invention is to provide a high-density array transducer that can effectively solve the problems in the prior art.

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

[0006] A high-density area array transducer includes a protective frame. Side plates are fixedly connected to the rear left and rear right ends of the protective frame. Three first screws are inserted through the front ends of the two side plates. Screw holes are provided at the four corners of the front end of the protective frame. Second screws are threaded through the four screw holes. A mounting plate is inserted through the outer surfaces of the four second screws. An installation device is fixedly connected to the front end of the mounting plate. A transducer body is disposed inside the protective frame. Several cables are fixedly installed at the front end of the transducer body.

[0007] The installation device includes a connecting frame, the rear end of which has a plurality of through holes, the lower end of which has a plurality of vertically through grooves, the lower inner wall of which is fixedly connected with a plurality of clamping components, and the upper end of which is snapped with an L-shaped connecting cover, the front end of which is provided with a viewing glass.

[0008] Preferably, the front end of the mounting plate has several second through holes that are the same size as the first through hole and are in the same position.

[0009] By adopting the above technical solution, a second through hole with the same size and position as the first through hole is opened at the front end of the mounting plate, which can ensure that the cable passes through smoothly, accurately lays out the cable, reduces cable bending and tangling, ensures stable signal transmission, and improves the overall working stability of the transducer.

[0010] Preferably, the mounting plate is detachably connected to the protective frame via four second screws.

[0011] By adopting the above technical solution, the mounting plate is detachably connected to the protective frame via four second screws, facilitating quick assembly and disassembly of the transducer in different scenarios. During later maintenance and repair, components can be easily separated, reducing repair difficulty. The mounting plate or protective frame can also be replaced as needed, improving operational flexibility.

[0012] Preferably, the directional grooves are distributed in parallel at the lower end of the connecting frame.

[0013] By adopting the above technical solution, the cable routing channels are distributed parallel to each other at the lower end of the connecting frame, allowing for neat and orderly cable routing and preventing messy cable crossings. Neat routing facilitates stable signal transmission, avoids signal interference caused by cable tangling, and also makes subsequent cable inspection and management easier.

[0014] Preferably, the visible glass is embedded in the front end of the L-shaped connecting cover, and the visible glass is tightly fitted to the front edge of the L-shaped connecting cover.

[0015] By adopting the above technical solution, the viewing glass is tightly embedded in the front end of the L-shaped connecting cover, which can effectively block dust, moisture and other impurities from entering the connecting frame and protect internal components such as cables, while not hindering operators from viewing the internal situation through the glass, making it easier to detect potential faults in a timely manner and ensuring the stable operation of the transducer.

[0016] Preferably, several of the cables extend into the connection frame through the corresponding first and second through holes.

[0017] By adopting the above technical solution, the cable extends through the corresponding insertion hole into the connection frame, realizing orderly wiring, avoiding cable exposure and tangling, reducing wear and signal interference risks, ensuring stable signal transmission, and facilitating centralized management of the cable, thereby improving the overall reliability of the transducer.

[0018] Preferably, the clamping assembly includes a support rod, the front inner wall of the support rod is movably connected to a bidirectional screw via a bearing, the rear end of the bidirectional screw is fixedly connected to a fixing rod, the rear end of the fixing rod is fixedly connected to a handwheel, the front side and the rear side of the outer surface of the bidirectional screw are threadedly connected to movable loops, the outer surfaces of the two movable loops are fixedly connected to arc-shaped clamping plates, and the lower end of the support rod is fixedly connected to the lower inner wall of the connecting frame.

[0019] By adopting the above technical solution, the clamping assembly is cleverly designed, and the spacing of the arc-shaped clamping plates can be flexibly adjusted by rotating the handwheel to accommodate cables of different quantities and thicknesses. The support rod provides stable support, ensuring that the cables are firmly clamped, effectively preventing cable swaying and displacement, and ensuring stable signal transmission when the transducer is working.

[0020] Preferably, the fixing rod passes through the rear inner wall of the support rod and extends to the rear end of the support rod, and the inner surfaces of both arc-shaped clamping plates are provided with anti-slip pads.

[0021] By adopting the above technical solution—the fixed rod inserts into the support rod and extends backward—smooth handwheel operation and convenient adjustment are ensured. The anti-slip pad on the inner surface of the arc-shaped clamping plate significantly increases friction, firmly gripping the cable and effectively preventing cable slippage, thus ensuring cable stability during transducer operation.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1. This utility model, through its unique installation structure design, greatly enhances stability and flexibility. The protective frame is fixed in place by side plates and first screws, and the screw holes at the four corners of the front end cooperate with second screws to easily connect the mounting plate, and then the mounting device. This modular installation method allows for flexible selection of the combination of mounting plate and mounting device according to different installation environments. For example, in a confined testing environment, a compact mounting device can be selected, and the installation angle of the transducer can be finely adjusted by adjusting the position of the second screw in the screw hole, ensuring that it can accurately align with the testing area, meeting the installation requirements in complex environments, and significantly enhancing the flexibility of the installation structure. At the same time, the multi-screw fastening and the tight connection between components ensure that the entire installation structure remains stable during operation, effectively preventing transducer loosening due to vibration, displacement, and other factors, and ensuring its stable operation.

[0024] 2. In this utility model, the first through-hole in the connecting frame of the installation device precisely corresponds to the second through-hole on the mounting plate, allowing the cable to pass through and penetrate deep into the connecting frame in an orderly manner. This ingenious design completely eliminates the need for the cable to operate in harsh external environments, greatly avoiding the risk of wear and tear caused by daily friction and accidental collisions. The guide groove at the lower end of the connecting frame acts like a safety track tailor-made for the cable, not only guiding the cable's path but also working seamlessly with the clamping components. Operating the handwheel of the clamping components causes the bidirectional screw to rotate, driving the movable sling and the arc-shaped clamping plate to move flexibly. The clamping force is precisely controlled according to the actual number and thickness of the cables, ensuring both secure cable fixation and preventing potential damage caused by over-clamping. When the transducer is subjected to external pulling force, the clamping components act like a sturdy buffer shield, evenly distributing the pulling force and effectively preventing the cable from breaking due to excessive force at a single point. This comprehensively extends the cable's service life, laying a solid foundation for the transducer's continuous and stable operation and ensuring that its normal operation is never interfered with by cable damage.

[0033] Please see Figure 1-4 This utility model provides a technical solution:

[0034] A high-density area array transducer includes a protective outer frame 1. Side plates 2 are fixedly connected to the rear left and rear right ends of the protective outer frame 1. Three first screws 3 are inserted through the front ends of the two side plates 2. Screw holes 4 are opened at the four corners of the front end of the protective outer frame 1. Second screws 5 are threaded through the four screw holes 4. A mounting plate 6 is inserted through the outer surface of the four second screws 5. A mounting device 7 is fixedly connected to the front end of the mounting plate 6. A transducer body 8 is arranged inside the protective outer frame 1. Several cables 9 are fixedly installed at the front end of the transducer body 8.

[0035] In this embodiment, the mounting device 7 includes a connecting frame 71. The rear end of the connecting frame 71 has several first through holes 72 that pass through from front to back. The lower end of the connecting frame 71 has several vertically through grooves 73. Several clamping components 74 are fixedly connected to the lower inner wall of the connecting frame 71. An L-shaped connecting cover 75 is snapped onto the upper end of the connecting frame 71. A viewing glass 76 is provided at the front end of the L-shaped connecting cover 75. The front end of the mounting plate 6 has several second through holes that are the same size as the first through holes 72 and are in the same position. The mounting plate 6 is detachably connected to the protective outer frame 1 by four second screws 5. The grooves 73 are distributed in parallel at the lower end of the connecting frame 71. The viewing glass 76 is embedded in the front end of the L-shaped connecting cover 75, and the viewing glass 76 is tightly fitted to the front edge of the L-shaped connecting cover 75. Several cables 9 extend into the connecting frame 71 through the corresponding first through holes 72 and second through holes.

[0036] Through the above scheme: the first through hole 72 at the rear end of the connecting frame 71 and the second through hole corresponding to the front end of the mounting plate 6 provide a channel for the cable 9, allowing the cable 9 to extend smoothly into the interior of the connecting frame 71. Parallel routing grooves 73 at the lower end of the connecting frame 71 guide the cable 9. The mounting plate 6 is detachably connected to the protective outer frame 1 by four second screws 5, facilitating installation and adjustment. The L-shaped connecting cover 75 is snapped onto the upper end of the connecting frame 71, and its front end is fitted with a viewing glass 76 that fits snugly against the edge, protecting the internal structure while allowing easy observation of the cable 9 and other components inside the connecting frame 71.

[0037] In this embodiment, the clamping assembly 74 includes a support rod 741. A bidirectional screw 742 is movably connected to the front inner wall of the support rod 741 via a bearing. A fixing rod 743 is fixedly connected to the rear end of the bidirectional screw 742. A handwheel 744 is fixedly connected to the rear end of the fixing rod 743. Movable loops 745 are threadedly connected to both the front and rear sides of the outer surface of the bidirectional screw 742. Arc-shaped clamping plates 746 are fixedly connected to the outer surfaces of both movable loops 745. The lower end of the support rod 741 is fixedly connected to the lower inner wall of the connecting frame 71. The fixing rod 743 passes through the rear inner wall of the support rod 741 and extends to the rear end of the support rod 741. Anti-slip pads are provided on the inner surfaces of both arc-shaped clamping plates 746.

[0038] Through the above scheme: when it is necessary to fix the cable, turn the handwheel 744. Since the handwheel 744 is fixed to the rear end of the fixing rod 743, and the fixing rod 743 is connected to the double-acting screw 742, the handwheel 744 drives the fixing rod 743 and the double-acting screw 742 to rotate together. The front and rear sides of the double-acting screw 742 are respectively threaded with movable loops 745. When the screw rotates, according to the thread characteristics, the two movable loops 745 will move towards or in opposite directions along the screw axis. The movable loops 745 drive the arc-shaped clamping plate 746 fixed to them to move accordingly, thereby flexibly adjusting the clamping position and force on the cable according to the number and thickness of the cable 9. The anti-slip pad on the inner surface of the arc-shaped clamping plate 746 increases the friction between it and the cable, preventing the cable from slipping. The lower end of the support rod 741 is fixed to the lower inner wall of the connecting frame 71, providing stable support for the entire clamping assembly 74, ensuring the cable is firmly clamped, and ensuring the stability of the cable when the transducer is working.

[0039] It should be noted that this utility model is a high-density area array transducer. In use, firstly, the protective frame 1 is firmly fixed to the target position using the side plate 2 and three first screws 3, completing the basic installation. Next, the mounting plate 6 is tightly connected to the screw holes 4 at the four corners of the front end of the protective frame 1 using four second screws 5. Then, the mounting device 7 is installed on the front end of the mounting plate 6. In confined spaces, a mounting device 7 of suitable size can be selected as needed, and the angle of the transducer body 8 can be adjusted by finely adjusting the position of the second screws 5 in the screw holes 4 to ensure accurate alignment with the detection area. After completing the above installation, the L-shaped connecting cover 75 is opened to facilitate the adjustment of the cable 9 arrangement. Several cables 9 at the front end of the transducer body 8 are sequentially passed through the first and second insertion holes corresponding to the front end of the mounting plate 6 and the rear end of the connecting frame 71, extending them into the interior of the connecting frame 71. Then, operate the clamping assembly 74, turn the handwheel 744 to rotate the fixing rod 743 and the bidirectional screw 742, causing the two movable loops 745 connected by threads on the front and rear sides of the outer surface to move the arc-shaped clamping plate 746. Adjust the clamping force flexibly according to the number and thickness of the cables 9 to securely fix them. After clamping, place the other end of the cable 9 into the routing groove 73 at the lower end of the connecting frame 71. At this time, the transducer body 8 begins to work, converting electrical energy into acoustic energy for detection and other operations. The detection signal is transmitted through the cable 9 to external equipment for processing and analysis.
