Description

Technical Field

[0001] This utility model relates to the field of sound velocity meter technology, and in particular to a surface sound velocity meter probe mounting mechanism. Background Technology

[0002] Currently, the sound velocity meter is a professional instrument for measuring the speed of sound wave propagation in a medium. Its detection probe is the core component for signal transmission and reception. The two work together to accurately obtain sound velocity data and are widely used in industrial testing, marine exploration, materials analysis and other fields.

[0003] However, currently, when using a sound velocity meter to test materials, to avoid the sound velocity meter being separated during daily storage, the probe needs to be continuously twisted to reconnect it. This process requires constant twisting of the connection end, which can easily cause the connecting cable and probe to rotate and swing, potentially colliding with external objects and causing damage. This makes the assembly process overly cumbersome and affects the accuracy of subsequent measurements. Therefore, we propose a surface sound velocity meter probe mounting mechanism. Summary of the Invention

[0004] The main objective of this invention is to provide a surface acoustic velocity meter probe mounting mechanism, which 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: A surface acoustic velocity meter probe mounting mechanism includes an acoustic velocity meter body and a detection probe. A connecting sleeve is provided on the side of the acoustic velocity meter body. A plug-in tube is detachably installed inside the connecting sleeve. A connecting cable is fixedly connected to the side of the plug-in tube. The side of the connecting cable is electrically connected to the detection probe. The outer side of the connecting sleeve is provided with a plugging mechanism, and the outer side of the plugging sleeve is provided with a stop mechanism.

[0006] As an optional solution to the technical solution of this application, the insertion mechanism includes a limiting plug rod and a reset spring. A fixed frame is fixedly installed on the outer wall of the connecting sleeve, and a movable plate is slidably installed inside the fixed frame. The limiting plug rod is fixedly installed in the middle of the side end of the movable plate.

[0007] As an optional solution to the technical solution of this application, a transmission rod is fixedly installed at the middle of the other side of the movable plate, and the side end of the transmission rod passes through the side wall of the fixed frame and slides from the inside of the fixed frame to its outside. A reset spring is movably sleeved on the outside of the transmission rod, and the two ends of the side of the reset spring are respectively movably attached to the outer wall of the movable plate and the inner wall of the fixed frame.

[0008] As an optional solution to the technical solution of this application, a sliding groove is provided in the middle of the side of the fixed frame near the sound velocity meter body, and the limiting rod is slidably installed inside the sliding groove. A movable groove is provided in the middle of the side of the fixed frame away from the sound velocity meter body, and the transmission rod is slidably installed inside the movable groove.

[0009] As an optional solution to the technical solution of this application, a push plate is fixedly installed on the top of the transmission rod on the side away from the movable plate, and the push plate is movably disposed outside the fixed frame.

[0010] As an optional solution to the technical solution of this application, the abutment mechanism includes a fixing block, a guide groove is provided on the outer side of the connecting sleeve, the fixing block is fixedly installed on the outer wall of the plug-in cylinder, and the fixing block is slidably installed inside the guide groove, and a limit slot is provided on the side of the fixing block near the sound velocity meter body.

[0011] Compared with the prior art, the present invention has the following beneficial effects: This application discloses a surface acoustic velocity meter probe mounting mechanism. An L-shaped guide groove is provided on the outer side of the connecting sleeve at the side end of the acoustic velocity meter body, along with a fixing frame. When connecting the connecting sleeve and the plug-in cylinder to connect the connecting cable and the detection probe to the acoustic velocity meter body, the operator only needs to align the fixing block located on the outer wall of the plug-in cylinder with the guide groove, push the plug-in cylinder, and rotate it a short distance. As the fixing block moves along the inner wall of the guide groove, its side wall contacts the side end of the limiting plug rod. With the continuous movement of the fixing block... The side wall of the fixed block abuts against the limiting rod, causing it to retract into the fixed frame. This allows the side end of the limiting rod to move along the outer wall of the fixed block until it reaches the outside of the limiting slot. Then, under the reverse pushing action of the return spring, the side end of the limiting rod can be pushed and inserted into the limiting slot. The interaction between the limiting rod and the limiting slot achieves the fixing of the fixed block, thereby ensuring the connection stability between the connecting sleeve and the insertion sleeve, simplifying the operation steps required for overall assembly, and improving the disassembly and assembly efficiency of the detection probe and the sound velocity meter body.

[0014] like Figure 1-3 As shown, this utility model provides a technical solution: a surface acoustic velocity meter probe mounting mechanism, wherein a connecting sleeve 11 is provided on the side end of the acoustic velocity meter body 1, and a plug tube 12 is detachably installed inside the connecting sleeve 11. A connecting cable 13 is fixedly connected to the side end of the plug tube 12, and the side end of the connecting cable 13 is electrically connected to the detection probe 14.

[0015] In this technical solution (through Figure 1 , Figure 2 and Figure 3 As shown, a plug-in mechanism is provided on the outside of the connecting sleeve 11. The plug-in mechanism includes a limiting plug rod 24 and a return spring 27. A fixed frame 23 is fixedly installed on the outer wall of the connecting sleeve 11. A movable plate 25 is slidably installed inside the fixed frame 23. The limiting plug rod 24 is fixedly installed in the middle of the side end of the movable plate 25. The limiting plug rod 24 passes through the side wall of the fixed frame 23 and extends from the inner wall of the fixed frame 23 to its outer side. A transmission rod 26 is fixedly installed in the middle of the other side of the movable plate 25. The side end of the transmission rod 26 passes through the side wall of the fixed frame 23 and slides from the inside of the fixed frame 23 to its outer side. The outer side of the transmission rod 26 is movably sleeved with the return spring 27. The two ends of the side of the return spring 27 are respectively movably attached to the outer wall of the movable plate 25 and the inner wall of the fixed frame 23.

[0016] In this technical solution (through Figure 1 , Figure 2 and Figure 3 As shown, a sliding groove 3 is provided in the middle of the side of the fixed frame 23 near the sound velocity meter body 1, and the limiting rod 24 is slidably installed inside the sliding groove 3. A movable groove 31 is provided in the middle of the side of the fixed frame 23 away from the sound velocity meter body 1, and the transmission rod 26 is slidably installed inside the movable groove 31.

[0017] In this technical solution (through Figure 1 , Figure 2 and Figure 3 As shown), an abutment mechanism is provided on the outside of the plug-in tube 12. The abutment mechanism includes a fixing block 2. A guide groove 22 is provided on the outside of the connecting sleeve 11. The guide groove 22 is L-shaped. The fixing block 2 is fixedly installed on the outer wall of the plug-in tube 12. The fixing block 2 is slidably installed inside the guide groove 22. A limit slot 21 is provided on the side of the fixing block 2 near the sound velocity meter body 1. The diameter of the abutment block is the same as the inner diameter of the limit slot 21.

[0018] In some technical solutions (through Figure 1 , Figure 2 and Figure 3 As shown), a push plate 4 is fixedly installed on the top of the transmission rod 26 on the side away from the movable plate 25, and the push plate 4 is movably set on the outside of the fixed frame 23.

[0019] During operation, when assembling and connecting the detection probe 14 and the sound velocity meter body 1, initial docking is first achieved by the cooperation of the connecting sleeve 11 and the plug-in tube 12. At this time, the operator aligns the plug-in tube 12 with the connecting sleeve 11, so that the fixing block 2 on the outer wall of the plug-in tube 12 corresponds to the guide groove 22 on the outer side of the connecting sleeve 11. Then, the plug-in tube 12 is pushed and twisted a short distance, allowing the fixing block 2 to slide along the inside of the guide groove 22. As the fixing block 2 continues to move within the guide groove 22, the side wall of the fixing block 2 will contact the limiting rod 24 in the fixing frame 23. As the fixing block 2 continues to move, its side wall will exert a resisting effect on the limiting rod 24, causing the limiting rod 24 to move towards the fixing frame 23. During the internal contraction process, the limiting rod 24 drives the movable plate 25, which is fixedly connected to it, to slide inside the fixed frame 23. The movement of the movable plate 25 will compress the return spring 27 sleeved on the outside of the transmission rod 26, so that the return spring 27 is in a compressed state. When the fixed block 2 continues to slide until the limiting slot 21 opened on its side wall corresponds to the position of the limiting rod 24, the abutment of the fixed block 2 against the limiting rod 24 disappears. At this time, the return spring 27 in the compressed state will generate a reverse thrust, pushing the movable plate 25 to move closer to the fixed block 2. The movable plate 25 then drives the limiting rod 24 to move synchronously, so that the side end of the limiting rod 24 is pushed and inserted into the limiting slot 21. With the cooperation of the limiting rod 24 and the limiting slot 21, the fixing block 2 is stably fixed in the guide groove 22, thereby realizing the stable connection between the connecting sleeve 11 and the plug-in sleeve 12. After the detection probe 14 is electrically connected to the sound velocity meter body 1 through the connecting cable 13, the bottom surface of the detection probe 14 is then attached to the surface of the workpiece to be detected, and the sound velocity meter body 1 is started. The analysis and detection of the workpiece are realized by combining the operation of the detection probe 14 and the sound velocity meter body 1. If it is necessary to disassemble and separate the detection probe 14 and the sound velocity meter body 1, the operator only needs to push the push plate 4 at the top of the side of the transmission rod 26 away from the movable plate 25. The push plate 4 drives the transmission rod 26 to slide in the movable groove 31 of the fixed frame 23. The transmission rod 26 then pulls the movable plate 25 to slide inside the fixed frame 23. The movable plate 25 drives the limiting plug 24 to be pulled out from the limiting slot 21 and retracted into the fixed frame 23. At the same time, the movable plate 25 squeezes the reset spring 27 again. At this time, the fixing effect of the limiting plug 24 on the fixed block 2 is released. The operator can then twist and pull the plug tube 12 in the opposite direction to make the fixed block 2 slide away along the guide groove 22, and finally realize the separation of the connecting sleeve 11 and the plug tube 12, thus completing the disassembly of the detection probe 14 and the sound velocity meter body 1.
