Abstract
Description
Technical Field
[0001] This utility model relates to the field of pile foundation testing instruments, and in particular to a wire fixing device for a low-strain pile foundation testing instrument. Background Technology
[0002] The low-strain pile foundation tester is a device that uses the reflected wave method to detect the integrity of pile foundations and determine pile defects. It can be used to test cast-in-place piles and driven piles, as well as for testing structures with exposed top surfaces (such as bridge piers). The low-strain pile foundation tester can be used to standardize pile foundations and help relevant departments to enforce the standardization of pile foundations, thereby ensuring the quality of various building facilities.
[0003] Currently, low-strain pile foundation testing instruments are generally designed with relatively long connecting cables to adapt to different working environments. This often results in the cable being too long during use, so operators use cable ties to bundle the excess cable. For example... Figure 1-2 As shown, the connecting wire is connected to the socket of the low-strain pile foundation tester via a plug. During use, it is easily subjected to external forces, which may cause poor contact between the plug and the socket, or even cause the plug and the socket to detach, affecting the normal progress of the testing process. Summary of the Invention
[0004] In view of the shortcomings of the prior art, the technical problem to be solved by this patent application is how to provide a cable fixing device for a low-strain pile foundation testing instrument that can reinforce the connection between the plug of the connecting cable and the socket of the low-strain pile foundation testing instrument, making it stable, reliable and easy to use.
[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:
[0006] A wire fixing device for a low-strain pile foundation tester, the low-strain pile foundation tester includes a tester body and a connecting line, a socket is provided on the top of the tester body, one end of the connecting line has a plug that is plugged into the socket, a rubber block is fixed on the outside of the plug, and the wire fixing device includes a first wire fixing frame and a second wire fixing frame.
[0007] The first cable holder includes a first half-cylinder, with a first limiting ring protruding inward from the upper end of the first half-cylinder. The first limiting ring is coaxially arranged with the first half-cylinder, and a first wire passage is opened at the end of the first limiting ring away from the first half-cylinder. The second cable holder includes a second half-cylinder, with a second limiting ring protruding upward from the upper end of the second half-cylinder. The second limiting ring is coaxially arranged with the second half-cylinder, and a second wire passage is opened at the end of the second limiting ring away from the second half-cylinder. When the first half-cylinder and the second half-cylinder are fitted together to form a cylinder, the first limiting ring is located below the second limiting ring. The lower ends of both the first half-cylinder and the second half-cylinder are connected to the detector body through a connecting structure.
[0008] Thus, the low-strain pile foundation testing instrument includes a testing instrument body and a connecting cable. A socket is located on the top of the testing instrument body, and one end of the connecting cable has a plug that mates with the socket. A rubber block is fixed to the outside of the plug, which is the structure of the currently used low-strain pile foundation testing instrument disclosed in the background art. To address the issue of unstable connection between the plug and socket of the connecting cable, a fixing device is configured to prevent the plug from detaching from the socket. During installation, the plug of the connecting cable is plugged into the socket on the testing instrument body. The first cable holder is aligned with the cable, and the cable enters the first limiting ring through the first cable passage. The first half-cylinder moves towards the testing instrument body and connects to the testing instrument body through the connecting structure. Then, the second cable holder is aligned with the cable, and the cable passes through the second cable passage and enters the second limiting ring. The second half-cylinder moves towards the testing instrument body and fits against the first half-cylinder. The second limiting ring presses against the first limiting ring, and the second half-cylinder connects to the testing instrument body through the connecting structure, completing the installation of the cable fixing device. By using the wire fixing device, the first and second limiting rings limit the rubber block, ensuring that the plug is stably engaged with the socket and preventing the plug from coming off.
[0009] Preferably, the connection structure includes a plastic buckle fixedly installed at the lower end of the first half-cylinder and the second half-cylinder. The plastic buckle is inverted U-shaped and has slots at both ends. The detector body is fixedly installed with a mounting base facing the socket. The mounting base has protruding blocks on both sides that can engage with the buckle.
[0010] Preferably, the two ends of the buckle have outwardly curved and extended outer edges.
[0011] Preferably, the rubber block is shaped like a frustum at one end near the wire, and both the first limiting ring and the second limiting ring have an inner conical surface that conforms to the outer surface of the frustum.
[0012] Preferably, the first cable holder is integrally formed by injection molding, and the second cable holder is integrally formed by injection molding.
[0013] Preferably, the outer surface of the card block is a slope.
[0014] In summary, the cable fixing device for this low-strain pile foundation testing instrument has the advantages of reinforcing the connection between the plug of the connecting cable and the socket of the low-strain pile foundation testing instrument, ensuring stability and reliability, and being easy to use.

[0025] like Figure 1-9 As shown, a wire fixing device for a low-strain pile foundation tester is provided. The low-strain pile foundation tester includes a tester body 1 and a connecting line 2. A socket 3 is provided on the top of the tester body. One end of the connecting line has a plug 4 that is plugged into the socket. A rubber block 5 is fixed on the outside of the plug. The wire fixing device includes a first wire fixing frame 6 and a second wire fixing frame 7.
[0026] The first cable holder includes a first half-cylinder 8, with a first limiting ring 9 protruding inward from the upper end of the first half-cylinder. The first limiting ring is coaxial with the first half-cylinder, and a first cable passage 10 is provided at the end of the first limiting ring away from the first half-cylinder. The second cable holder includes a second half-cylinder 11, with a second limiting ring 12 protruding upward from the upper end of the second half-cylinder. The second limiting ring is coaxial with the second half-cylinder, and a second cable passage 13 is provided at the end of the second limiting ring away from the second half-cylinder. When the first half-cylinder and the second half-cylinder are fitted together to form a cylinder, the first limiting ring is located below the second limiting ring. The lower ends of both the first half-cylinder and the second half-cylinder are connected to the detector body through a connecting structure.
[0027] Thus, the low-strain pile foundation testing instrument includes a testing instrument body and a connecting cable. A socket is located on the top of the testing instrument body, and one end of the connecting cable has a plug that mates with the socket. A rubber block is fixed to the outside of the plug, which is the structure of the currently used low-strain pile foundation testing instrument disclosed in the background art. To address the issue of unstable connection between the plug and socket of the connecting cable, a fixing device is configured to prevent the plug from detaching from the socket. During installation, the plug of the connecting cable is plugged into the socket on the testing instrument body. The first cable holder is aligned with the cable, and the cable enters the first limiting ring through the first cable passage. The first half-cylinder moves towards the testing instrument body and connects to the testing instrument body through the connecting structure. Then, the second cable holder is aligned with the cable, and the cable passes through the second cable passage and enters the second limiting ring. The second half-cylinder moves towards the testing instrument body and fits against the first half-cylinder. The second limiting ring presses against the first limiting ring, and the second half-cylinder connects to the testing instrument body through the connecting structure, completing the installation of the cable fixing device. By using the wire fixing device, the first and second limiting rings limit the rubber block, ensuring that the plug is stably engaged with the socket and preventing the plug from coming off.
[0028] In implementation, the connection structure includes plastic clips 14 fixedly installed at the lower ends of the first and second half-cylinders. The plastic clips are inverted U-shaped, with latches 15 at both ends. A mounting base 16 is fixedly installed on the detector body opposite the socket. The mounting base has protruding locking blocks 17 on both sides that can engage with the clips. By using the plastic clips to engage with the mounting base, the first and second half-cylinders are fixed in position, making installation simple and operation straightforward.
[0029] In practice, the buckle has outwardly curved outer edges 18 at both ends. This allows the buckle to be rotated outwards by holding the outer edges until it disengages from the locking block, and then the wire fixing device can be removed.
[0030] In practice, the rubber block is shaped like a frustum near the end of the wire, and both the first and second limiting rings have an inner conical surface 19 that conforms to the outer surface of the frustum. The engagement of the frustum and the inner conical surface makes the installation of the wire more stable and reliable.
[0031] In practice, both the first and second cable holders are integrally molded using injection molding, facilitating manufacturing.
[0032] In practice, the outer surface of the locking block is beveled to facilitate engagement with the latch.
[0033] Finally, it should be noted that those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims and their equivalents, this utility model also intends to include these modifications and variations.
