[0032] The invention provides a fixing structure applied to echo testing of ultrasonic equipment and a positioning device having the fixing structure.

[0033] Please refer to Figure 1 The fixed structure applied to the echo test of the ultrasonic device includes a connecting component 10 and a fixing component 20, the ultrasonic device includes an ultrasonic probe 30, the ultrasonic probe 30 is connected to the fixing component 20, and the fixing component 20 is used to limit the ultrasonic probe 30; the connecting component 10 includes a connecting rod 11 and a connecting seat 12, the connecting rod 11 is connected to one side of the connecting seat 12, and the other side of the connecting seat 12 is connected to the fixing component 20; the fixing component 20 includes a frame 21 and a rotating connecting member 22, the frame 21 includes a first frame 211 close to the connecting seat 12 and a second frame 212 away from the connecting seat 12; the rotating connecting member 22 is rotatably connected to the first frame 211 and the second frame 212, so that the first frame 211 and the second frame 212 can rotate with the rotating connecting member 22 as the rotating axis.

[0034] In the technical solution proposed in the present application, the fixed structure applied to the echo test of the ultrasonic device includes a connecting component 10 and a fixing component 20, the connecting component 10 includes a connecting rod 11 and a connecting seat 12, the fixing component 20 includes a frame 21 and a rotating connecting member 22, the frame 21 includes a first frame 211 and a second frame 212, the first frame 211 and the second frame 212 can rotate relative to each other with the rotating connecting member 22 as a rotating axis; the connecting seat 12 is connected to the fixing component 20, and when positioning measurement is performed on different ultrasonic devices, since the ultrasonic devices are fixedly connected to the fixing component 20, positioning measurement can be performed on different ultrasonic devices by directly replacing the fixing component 20, thereby avoiding the problem that the clamping structure of the ultrasonic device in the prior art is a fixed structure, resulting in cumbersome disassembly and assembly of the ultrasonic device and low disassembly and assembly efficiency when positioning measurement is performed on different ultrasonic devices.

[0035] In an optional embodiment, the first frame body 211 and the second frame body 212 are combined to form a first accommodating cavity (not marked), and the ultrasonic probe 30 is accommodated in the first accommodating cavity. When the outer side walls of the ultrasonic probe 30 are respectively in contact with the first frame body 211 and the second frame body 212 and are clamped by the first frame body 211 and the second frame body 212, the ultrasonic probe 30 and the frame body 21 remain relatively still, and the user can position and measure different ultrasonic probes 30 by replacing the fixing component 20.

[0036] For details, please refer to Figure 1 , the diameter of the openings on both sides of the first accommodating cavity along the extension direction of the rotating connecting member 22 is smaller than the diameter of the inner wall of the first accommodating cavity, thereby preventing the ultrasonic device from moving out of the openings on both sides of the first accommodating cavity. In another embodiment, please refer to Figure 4 The outer shell portion of the ultrasonic probe 30 is accommodated in the first accommodating cavity, and the first frame 211 and the second frame 212 clamp the ultrasonic probe 30 to prevent the ultrasonic device from moving out.

[0037] In another optional embodiment, a fixing portion (not shown) is provided on the peripheral side of the frame 20, and the ultrasonic probe 30 is detachably connected to the fixing portion, and a plurality of ultrasonic probes 30 are detachably connected to different fixing portions, thereby avoiding the problem of cumbersome disassembly and assembly of the ultrasonic equipment and low disassembly and assembly efficiency.

[0038] In a preferred embodiment, a first rotating portion (not marked) is provided at one end of the first frame body 211, and a second rotating portion (not marked) is provided at one end of the second frame body 212. The rotating connector 22 also includes a rotating shaft, which passes through the first rotating portion and the second rotating portion, so that the first frame body 211 and the second frame body 212 can rotate around the rotating shaft.

[0039] Please refer to Figure 4 In another embodiment, the rotating connecting member 22 is a hinge, one end of the rotating connecting member 22 is fixedly connected to the first frame 211, and the other end is fixedly connected to the second frame 212, and the first frame 211 and the second frame 212 can rotate relative to each other under the drive of the hinge.

[0040] Please refer to Figures 1 to 3 In some optional embodiments, a positioning groove 121 is provided on one side of the connection base 12 close to the first frame 211, and a positioning protrusion 213 is provided on one side of the first frame 211 close to the connection base 12, and the positioning protrusion 213 is received in the positioning groove 121. In a specific embodiment, the positioning protrusion 213 is slidably connected to the positioning groove 121, so different ultrasonic devices can be replaced by combining and separating the positioning protrusion 213 and the positioning groove 121, avoiding the problem of difficulty in disassembling the ultrasonic device from the fixed tooling when replacing different ultrasonic devices for positioning, resulting in difficulty in replacing the ultrasonic device.

[0041] Furthermore, in a preferred embodiment, the positioning groove 121 is a dovetail groove, and the positioning protrusion 213 is a dovetail protrusion. In a specific embodiment, the dovetail groove can improve the accuracy and stability of the relative sliding of the positioning protrusion 213 and the positioning groove 121, and when the dovetail protrusion is received in the dovetail groove, since the size of the dovetail groove close to the first frame 211 is smaller than the size of the dovetail groove away from the first frame 211, the fixing component 20 can be limited along the direction facing the bottom of the positioning groove 121, so as to prevent the positioning protrusion 213 from being separated from the positioning groove 121, thereby improving the connection stability between the fixing component 20 and the connecting seat 12.

[0042] Please refer to Figures 1 to 4In some optional embodiments, a stop wall 122 is provided on the inner side wall of the positioning groove 121. In a specific embodiment, when the positioning protrusion 213 is received in the positioning groove 121, the bottom wall of the positioning protrusion 213 abuts against the stop wall 122. The stop wall 122 is used to limit the moving distance of the positioning protrusion 213 and to support the positioning protrusion 213 to prevent the positioning protrusion 213 from sliding out of the positioning groove 121.

[0043] In some optional embodiments, an elastic positioning member 123 is provided on the side wall of the connection seat 12 close to the first frame body 211, and a positioning hole 214 is provided on the side wall of the positioning protrusion 213 close to the connection seat 12, and the elastic positioning member 123 is received in the positioning hole 214. In a specific embodiment, the elastic positioning member 123 is provided with an inner side wall of the positioning groove 121, and when the positioning protrusion 213 abuts against the stop wall 122, the elastic positioning member 123 is received in the positioning hole 214, so as to prevent the positioning protrusion 213 and the positioning groove 121 from moving relative to each other along the extension direction of the positioning groove 121. In a preferred embodiment, the elastic positioning member 123 is a ball-end screw, wherein the ball-end screw is accommodated in the inner wall of the positioning groove 121, and the ball protrudes from the side wall. When the positioning protrusion 213 slides into the positioning groove 121, the positioning protrusion 213 applies force to the ball-end screw so that the ball is flush with the inner wall height of the positioning groove 121. When the positioning protrusion 213 abuts against the stop wall 122, the ball protrudes from the inner wall and is accommodated in the positioning hole 214 of the positioning protrusion 213, thereby limiting the relative movement of the positioning protrusion 213 and the positioning groove 121.

[0044] Please refer to Figures 1 to 4When the ultrasonic device is fixed, the first frame 211 and the second frame 212 rotate with the rotating connection 22 as the rotating axis. When the frame 21 fixes the ultrasonic device, the end of the first frame 211 away from the rotating connection 22 and the end of the second frame 212 away from the rotating connection 22 are fixedly connected to prevent the ultrasonic device from falling out of the frame 21. In some optional embodiments, the end of the first frame 211 away from the rotating connection 22 is provided with a clamping portion 215, and the end of the second frame 212 away from the rotating connection 22 is provided with a matching portion 216, and the clamping portion 215 is snap-connected with the matching portion 216, so as to ensure that the first frame 211 and the second frame 212 are relatively fixed. It can be understood that in another embodiment, the end of the first frame 211 away from the rotating connection 22 and the end of the second frame 212 away from the rotating connection 22 can also be other detachable connection methods, including but not limited to screw fixed connection or hinge connection.

[0045] Please refer to Figure 4 In some optional embodiments, a limiting protrusion 31 is provided on the outer wall of the ultrasonic probe 30, and a limiting groove 217 is provided on the side wall opposite to the first frame body 211 and the second frame body 212, and the limiting protrusion 31 is received in the limiting groove 217. In a specific embodiment, the limiting protrusion 31 and the limiting groove 217 are arranged to cooperate with each other, and when the ultrasonic device is received in the first accommodating cavity, the limiting protrusion 31 abuts against the limiting groove 217 to prevent the ultrasonic device and the fixing assembly 20 from moving relative to each other.

[0046] Please refer to Figure 5 The present invention further proposes a positioning device applied to an echo test of an ultrasonic device, wherein the positioning device applied to an echo test of an ultrasonic device comprises a fixed structure applied to an echo test of an ultrasonic device as described in any of the above-mentioned embodiments. The specific structure of the fixed structure applied to the echo test of an ultrasonic device refers to the above-mentioned embodiments. Since the fixed structure applied to the echo test of an ultrasonic device adopts all the technical solutions of all the above-mentioned embodiments, it has at least all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be described one by one here.

[0047] In the prior art, a stepper motor is used as a mobile control unit of an ultrasonic device. Each degree of freedom of the stepper motor operates independently, and the automatic alignment efficiency is low. In addition, the rotation center of the mobile control unit can only be fixed at the installation node of the stepper motor. This situation results in that when the position of the ultrasonic device is adjusted, the adjustment of the ultrasonic device not only requires a larger moving range, but also different degrees of freedom of the stepper motor may interfere with each other.

[0048] To solve the above problems of the stepper motor, please refer to Figure 5 In some optional embodiments, the positioning device for ultrasonic device echo test further includes a test platform 40 and a mechanical arm 50, one end of the mechanical arm 50 is fixedly connected to the test platform 40, and the other end is connected to the end of the connecting rod 11 away from the connecting seat 12. Specifically, the mechanical arm 50 can rotate or move the connecting component 10 and the fixing component 20 in a specified direction, and can use any point on the ultrasonic probe 30 as the rotation center, so that when positioning the ultrasonic device, the relative position of the fixing structure for ultrasonic device echo test on the test platform 40 can be calculated in advance, which simplifies the calculation complexity and operation process of the ultrasonic device and reduces the difficulty of positioning the ultrasonic device.

[0049] In a preferred embodiment, the mechanical arm 50 is a six-degree-of-freedom mechanical arm 50. In a specific embodiment, the six-degree-of-freedom mechanical arm 50 can perform displacement and rotation operations in three directions perpendicular to each other, thereby ensuring that the mechanical arm 50 can be accurately positioned.

[0050] Please refer to Figures 1 to 4 In some optional embodiments, a positioning step (not shown) is provided on one side of the connecting rod 11 close to the fixing assembly 20, and the connecting rod 11 abuts against the connecting seat 12. In a specific embodiment, the positioning step is used to limit the relative movement between the connecting seat 12 and the connecting rod 11, and prevent the connecting seat 12 from moving along the extending direction of the connecting rod 11.

[0051] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
