Technical Field

[0001] This utility model relates to the field of concrete ultrasonic testing probe replacement technology, and in particular to a snap-on quick-disassembly concrete ultrasonic testing probe replacement structure. Background Technology

[0002] Ultrasonic testing probes for concrete are important tools for detecting the internal structure and defects of concrete. Different frequencies of ultrasonic testing probes are required for concrete of different thicknesses.

[0003] Therefore, an ultrasonic thickness gauge with easy probe replacement, publication number CN220729196U, is described. First, the user squeezes the levers inwards and outwards. The levers flip and squeeze the spring clips, causing the top of the levers to disengage the locking head from the slot. This releases the locking head's restriction on the connecting rod. Then, the user pulls the connecting rod outwards, disengaging it from the connector. The male plug then disengages from the female socket, and the electronic compartment and sensor are removed. Next, the user takes out a new electronic compartment and sensor, aligns the connecting rod with the slot of the connector, and inserts it. The male plug is then inserted into the female socket. Finally, the user releases the levers on both sides, allowing the locking head to engage with the slot, fixing the connecting rod to the connector. The replacement of the electronic compartment and sensor is then complete.

[0004] This solution uses a snap-on assembly / disassembly mechanism, which enables quick assembly and disassembly of the probe through the cooperation of the clip rod, clip head, and clip slot. However, during installation, precise operation of the clip rod and clip head is required to ensure that the clip head can accurately engage with the clip slot. Utility Model Content

[0021] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] like Figures 1-4As shown, a snap-on quick-release concrete ultrasonic testing probe replacement structure includes a probe body 1 and a probe 2. The probe 2 is equipped with a male plug 14, and the probe body 1 has a female socket 13. The probe 2 can be connected to the probe body 1 by aligning the male plug 14 with the female socket 13. A connecting cylinder 3 for housing the female socket 13 is fixedly installed on the probe body 1. A plug 10 is fixedly installed at the central axis position inside the connecting cylinder 3. A connecting post 17 is fixedly installed at the end of the probe 2, and a connector 18 is fixedly installed at the end of the connecting post 17 to connect with the plug 10. By connecting the connector 18 to the plug 10, the male plug 14 can be aligned with the female socket 13 by rotating the probe 2. The connection between the connector 18 and the plug 10 ensures that the probe 2 can move relative to the probe body 1 along a fixed direction. To ensure smooth insertion of the male plug 14 into the female socket 13, the inner wall of the connecting cylinder 3 has two horizontally extending inwards, with a first socket 11 and a second socket 12 respectively provided at the two extensions. The first socket 11 and the second socket 12 are set at unequal distances from the central axis of the connecting cylinder 3. A first insertion rod 15 for insertion into the first socket 11 and a second insertion rod 16 for insertion into the second socket 12 are fixedly installed on the probe 2. In use, by utilizing the unequal distance between the first socket 11 and the second socket 12 from the central axis of the connecting cylinder 3, it is ensured that when the probe 2 is rotated with the connector 18 inserted into the plug cylinder 10, the first insertion rod 15 can only be inserted into the first socket 11 and the second insertion rod 16 can only be inserted into the second socket 12. Therefore, it is convenient for the assistant to blindly judge whether the male plug 14 and the female socket 13 are aligned.

[0024] A cover plate 4 is provided at the opening of the connecting cylinder 3, and a rotating shaft 8 is rotatably connected to the outer wall of the connecting cylinder 3 near the opening via a torsion spring. A rotating rod 9 is fixedly installed at the middle of the side of the rotating shaft 8, rotatably connected to the edge of the cover plate 4. The rotating rod 9 is perpendicular to the rotating shaft 8, and the central axis of the rotating shaft 8 is perpendicular to the central axis of the connecting cylinder 3. By rotating the rotating rod 9, the cover plate 4 can be horizontally rotated to detach from the opening of the connecting cylinder 3. By rotating the rotating shaft 8 again, the cover plate 4, detached from the opening of the connecting cylinder 3, can be swung upwards. The rotating shaft 8 is connected via a torsion spring, therefore... Figure 2 As shown, the torsion spring is under stress, which drives the rotating shaft 8 to rotate, thereby enabling the rotating rod 9 to drive the cover plate 4 to fit against the opening of the connecting cylinder 3.

[0025] A through hole 7 is provided at the center of the outer facade of the cover plate 4, and the through hole 7 is inserted into the connector 18. A first sliding groove 5 is provided at the edge of the outer facade of the cover plate 4. The first sliding groove 5 is distributed along the radial direction of the cover plate 4 and one end of the first sliding groove 5 extends to the through hole 7. An arc-shaped through groove 6 is provided on one side of the outer facade of the cover plate 4. The center of the arc-shaped through groove 6 coincides with the center of the rotating rod 9. One end of the arc-shaped through groove 6 extends to the side of the cover plate 4, and the other end is coaxially set with the through hole 7. The inner wall of the arc-shaped through groove 6 is slidably connected to the side surface of the connecting column 17. In this scheme, the diameter of the connector 18 is larger than the diameter of the connecting column 17, therefore the connector 18... When the end face of the cover plate 4 is attached to the outer surface and moved, it can only enter the first slide groove 5. Therefore, in order to facilitate the alignment of the connector 18 and the insert 10, in the case of blind operation, the operator only needs to move the connector 18 into the first slide groove 5, and then move the connector 18 along the first slide groove 5 to the through hole 7. It can then be automatically inserted into the insert 10 through the through hole 7. After the connector 18 is inserted into the insert 10, the cover plate 4 can be rotated and moved to disengage from the opening of the connecting cylinder 3 and the surface of the connecting column 17 by using the sliding of the arc-shaped through groove 6 and the connecting column 17.

[0026] Working principle: With the cover plate 4 sealing the opening of the connecting cylinder 3, the probe 2 is held and the connector 18 on the probe 2 is slid against the outer surface of the cover plate 4 into the first sliding groove 5. The connector 18 moves along the first sliding groove 5 to the through hole 7 and is automatically inserted into the insert cylinder 10 through the through hole 7. After the connector 18 is inserted into the insert cylinder 10, the cover plate 4 is rotated by rotating the rotating rod 9. The cover plate 4 is then smoothly rotated and disengaged from the opening of the connecting cylinder 3 and the surface of the connecting rod 17 by sliding the arc-shaped through groove 6 and the connecting post 17. Then, the probe 2 is rotated again so that the first insert rod 15 and the second insert rod 16 respectively fit against the two extended sides of the opening of the connecting cylinder 3. Furthermore, the sliding probe 2 ensures that the top ends of the first insertion rod 15 and the second insertion rod 16 are respectively in contact with the bottom surfaces of the two extended edges at the opening of the connecting cylinder 3. Only when the first insertion rod 15 is aligned with the first insertion hole 11 and the second insertion rod 16 is aligned with the second insertion hole 12 can the probe 2 drive the connector 18 to continue moving. At this time, the male plug 14 is aligned with the female plug 13. When the connector 18 is inserted into the cylinder 10, the first insertion rod 15 is inserted into the first insertion hole 11, and the second insertion rod 16 is inserted into the second insertion hole 12, the male plug 14 can only move towards the female plug 13 until the male plug 14 is inserted into the female plug 13, thus enabling the probe 2 to be installed smoothly.

[0027] The wiring diagrams of the detector body 1 and probe 2 in this utility model are common knowledge in the field, and their working principle is a well-known technology. The appropriate model is selected according to actual use. Therefore, the control method and wiring layout of the detector body 1 and probe 2 will not be explained in detail.

[0028] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
