Description

Technical Field

[0001] This utility model belongs to the technical field of ultrasonic flaw detectors, and in particular relates to an ultrasonic flaw detector. Background Technology

[0002] An ultrasonic flaw detector is an instrument used to detect, locate, evaluate, and diagnose various internal defects (cracks, inclusions, pores, etc.) in a workpiece. When ultrasonic waves propagate in the material being tested, the defects can be detected by considering the influence of the acoustic properties of the material's defects on the propagation of ultrasonic waves.

[0003] Existing flaw detection devices typically require the application of coupling agent during use, necessitating the carrying of a container filled with the agent and the manual application of the agent before testing. This process is not only cumbersome and inefficient, but also requires hand cleaning after application before testing. To address this issue, we have developed an ultrasonic flaw detector. Utility Model Content

[0004] The purpose of this invention is to provide an ultrasonic flaw detector that controls the flow of coupling agent by rotating the threaded rod downwards. Rotating the threaded rod to its lowest position also locks the probe, preventing it from moving during wiping of the probe's bottom and ensuring a more thorough cleaning. This method eliminates the need for manual application by hand and repeated hand cleaning, reducing operational steps. It solves the problem of existing flaw detectors requiring the application of coupling agent, necessitating the carrying of a container and manual application before testing. This is not only cumbersome and inefficient but also requires hand cleaning after application.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is an ultrasonic flaw detector, including an outer shell, an inner shell fixedly connected to the inner wall of the outer shell, a probe slidably connected to the inner wall of the inner shell, and a spring fixedly connected to the top of the probe;

[0007] The top of the spring is fixedly connected to the bottom of the inner shell. A threaded rod is threadedly connected to the inner wall of the inner shell. A locking rod is slidably connected inside the threaded rod. A knob is fixedly connected to the top of the locking rod. The outer surface of the knob is rotatably connected to the inner wall of the inner shell. Turning the threaded rod to the bottom locks the probe, so that the probe will not move when wiping the bottom of the probe, making it cleaner.

[0008] Furthermore, a data cable is fixedly connected to the top of the probe, the top of the data cable passes through the inner shell and extends to the outside, and an organism is fixedly connected to the end of the inner shell away from the probe. A storage box is fixedly connected to the left side of the organism, and a feed port is fixedly connected to the top of the storage box. A hydraulic pump is fixedly connected to the inner wall of the storage box, and the coupling agent is injected into the storage box through the feed port.

[0009] Furthermore, the hydraulic pump output end is fixedly connected to a delivery pipe, the top of the delivery pipe passes through the storage tank and extends to the outside, the end of the delivery pipe away from the storage tank is fixedly connected to the outer surface of the outer shell, and a storage tank is opened inside the outer shell, through which the coupling agent in the storage tank is delivered into the storage tank.

[0010] Furthermore, the housing has an inlet, and a push ring is slidably connected to the outer surface of the housing. A connecting rod is fixedly connected to the bottom of the push ring, and a scraper ring is fixedly connected to the bottom of the connecting rod. The scraper ring is used to discharge all the coupling agent in the storage tank, preventing the coupling agent from being squeezed back into the storage tank during application, thus preventing the storage tank from becoming contaminated and unusable.

[0011] Furthermore, the outer surface of the scraper ring is slidably connected to the inner wall of the storage tank, the inner side of the scraper ring is slidably connected to the outer surface of the probe, a second spring is fixedly connected inside the scraper ring, a connecting block is fixedly connected to the right side of the second spring, a baffle is slidably connected inside the push ring, a groove is provided on the left side of the baffle, and the outer surface of the connecting block is adapted to the inner wall of the groove. The baffle blocks the feed inlet to prevent coupling agent from re-entering the storage tank when cleaning the storage tank.

[0012] This utility model has the following beneficial effects:

[0013] 1. This utility model features a housing. When the housing is pressed down, the probe moves upward and compresses the spring, simultaneously contacting the bottom of the threaded rod. As the probe moves upward, the coupling agent in the storage tank flows out through the gap between the housing and the probe for application. This prevents excessive coupling agent leakage and waste due to excessive pressing force. Furthermore, turning the threaded rod to the bottom locks the probe, preventing it from moving when wiping the bottom, thus ensuring a more thorough cleaning. This method eliminates the need for manual application by hand and multiple hand cleaning steps, reducing operational steps.

[0014] 2. This utility model uses a scraper ring. When the scraper ring moves downward, it drives the connecting rod to move. Then, the moving connecting rod drives the scraper ring to move and scrape the inner wall of the storage tank. When the scraper ring moves downward, it drives the baffle to move. When the baffle reaches the bottom of the feed inlet, it closes the feed inlet to prevent excess coupling agent from falling into the top of the scraper ring and causing incomplete cleaning.

[0015] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

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.

[0025] Please see Figures 1-5 As shown, this utility model is an ultrasonic flaw detector, including a shell 101, an inner shell 105 fixedly connected to the inner wall of the shell 101, a probe 102 slidably connected to the inner wall of the inner shell 105, and a spring 107 fixedly connected to the top of the probe 102.

[0026] The top of spring 107 is fixedly connected to the bottom of inner shell 105. A threaded rod 106 is threadedly connected to the inner wall of inner shell 105. A locking rod 109 is slidably connected inside the threaded rod 106. A knob 108 is fixedly connected to the top of locking rod 109. The outer surface of knob 108 is rotatably connected to the inner wall of inner shell 105. When outer shell 101 is pressed downwards, probe 102 moves upwards, squeezing spring 107 and contacting the bottom of threaded rod 106. During the upward movement of probe 102, coupling agent in storage tank 211 flows out through the gap between outer shell 101 and probe 102 for application. This prevents excessive flow of coupling agent due to excessive pressing force. This avoids waste, and by turning the threaded rod 106 to the bottom to lock the probe 102, the probe 102 will not move when wiping its bottom, allowing for a more thorough cleaning. This method eliminates the need for manual hand application and repeated hand cleaning, reducing operational steps. A data cable 103 is fixedly connected to the top of the probe 102, and the top of the data cable 103 passes through the inner shell 105 and extends to the outside. The end of the inner shell 105 away from the probe 102 is fixedly connected to the body 104. A storage box 206 is fixedly connected to the left side of the body 104, and a feed inlet is fixedly connected to the top of the storage box 206. A hydraulic pump is fixedly connected to the inner wall of the storage box 206. 205. A conveying pipe 204 is fixedly connected to the output end of the hydraulic pump 205. The top of the conveying pipe 204 passes through the storage tank 206 and extends to the outside. The end of the conveying pipe 204 away from the storage tank 206 is fixedly connected to the outer surface of the outer shell 101. A storage tank 211 is provided inside the outer shell 101. A feed inlet 210 is provided inside the outer shell 101. A push ring 201 is slidably connected to the outer surface of the outer shell 101. A connecting rod 202 is fixedly connected to the bottom of the push ring 201. A scraper ring 203 is fixedly connected to the bottom of the connecting rod 202. The outer surface of the scraper ring 203 is slidably connected to the inner wall of the storage tank 211. The inner side of the scraper ring 203 is slidably connected to the outer surface of the probe 102. The scraper ring 203 is fixedly connected to the inner surface of the probe 102. A second spring 209 is connected. When the push ring 201 moves downward, it drives the connecting rod 202 to move. Then, the movement of the connecting rod 202 drives the scraper ring 203 to scrape the inner wall of the storage tank 211. When the scraper ring 203 moves downward, it drives the baffle 207 to move. When the baffle 207 reaches the bottom of the feed inlet 210, it closes the feed inlet 210 to prevent excess coupling agent from falling into the top of the scraper ring 203 and causing incomplete cleaning. A connecting block 208 is fixedly connected to the right side of the second spring 209. The baffle 207 is slidably connected inside the push ring 201. A groove is opened on the left side of the baffle 207. The outer surface of the connecting block 208 is adapted to the inner wall of the groove.

[0027] A specific application of this embodiment is as follows: The operator first places the device in the designated position, then starts the hydraulic pump 205. The hydraulic pump 205 begins to draw the coupling agent from the storage tank 206 into the delivery pipe 204 and then into the inlet 210, allowing it to enter the storage tank 211. Then, the range of motion of the probe 102 is adjusted according to the required amount of coupling agent. First, the knob 108 is rotated, which drives the locking rod 109 to rotate. Then, the rotation of the locking rod 109 drives the threaded rod 106 to rotate. As the threaded rod 106 rotates, it gradually moves downwards until it reaches the engagement point. Position the outer casing 101 appropriately, then place it in the rotating position so that the probe 102 contacts the skin. Press the outer casing 101 downwards; as it does so, the probe 102 moves upwards, compressing the spring 107 and contacting the bottom of the threaded rod 106. During this upward movement, the coupling agent in the storage groove 211 flows out through the notch between the outer casing 101 and the probe 102 for application. This prevents excessive pressure from causing waste of coupling agent. Finally, rotate the threaded rod 106 to its lowest position to lock the probe 102 in place. When wiping the bottom of probe 102, probe 102 does not move, allowing for a more thorough cleaning. After flaw detection, the coupling agent inside storage tank 211 needs to be cleaned. First, the threaded rod 106 is reset, then probe 102 is squeezed to the maximum extent, and then the push ring 201 is pushed downwards. The downward movement of the push ring 201 causes the connecting rod 202 to move, and then the movement of the connecting rod 202 causes the scraper ring 203 to move to scrape the inner wall of storage tank 211. When the scraper ring 203 moves downwards, it will cause the baffle 207 to move. When the baffle 207 reaches the feed inlet... After the bottom of 210 is reached, the feed inlet 210 is sealed to prevent excess coupling agent from falling into the top of the scraper ring 203. After the baffle 207 reaches the bottom of the feed inlet 210, it can no longer move, but the scraper ring 203 will continue to move. At this time, as the scraper ring 203 moves downward, the connecting block 208 will disengage from the baffle 207 and enter the scraper ring 203 to squeeze the spring 209. After the coupling agent inside the storage tank 211 is cleaned, when the scraper ring 203 returns to its upward position, when the connecting block 208 is aligned with the groove of the baffle 207, the connecting block 208 will re-enter the baffle 207 and drive it to move upward.
