Description

Technical Field

[0001] This utility model relates to the field of cable testing technology, specifically to a cable testing tool. Background Technology

[0002] As an indispensable basic component in modern industry and daily life, cables are widely used in many fields such as power transmission, communication, and electronic equipment connection. Their quality is directly related to the stability, safety, and reliability of the entire system.

[0003] Existing cable tensile testing machines have a relatively simple function, only used to test the tensile strength of cables. Although this single-item testing method can accurately evaluate the specific performance of cables, it has obvious limitations and cannot fully reflect the comprehensive performance of cables in actual use. In practical applications, cables often face a variety of complex environmental factors and mechanical effects. For example, during cable laying and movement, they frequently rub against surrounding objects, leading to surface wear. Traditional testing techniques cannot realistically simulate the various mechanical effects and environmental influences that cables suffer in actual use. Therefore, a cable testing tool is proposed to solve the above problems. Utility Model Content

[0004] In view of the shortcomings of the prior art, this utility model provides a cable testing tool to overcome the deficiencies of the prior art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A cable testing tool includes a test table. Two support frames are fixedly installed on the top of the test table. A cylindrical pad is fixedly installed near the top of each of the two support frames. A groove is formed on the top of each of the two cylindrical pads. A compression fixing mechanism is provided inside each of the two support frames. The two compression fixing mechanisms are respectively located above the two cylindrical pads. A tensile and abrasion resistance testing mechanism is provided at the front of the test table.

[0007] The tensile and abrasion resistance testing mechanism includes a sliding arm disposed in front of the test table. An electric push rod is fixedly installed on the top of the sliding arm and extends into it. A slider is fixedly installed on the telescopic end of the electric push rod. The slider is slidably installed inside the sliding arm. A frosting cylinder is rotatably installed on the back of the slider. A drive structure for driving the sliding arm to move is disposed in front of the test table.

[0008] Based on the above technical solution, the present invention can be further improved as follows.

[0009] Furthermore, the extrusion fixing mechanism includes a threaded rod threadedly installed inside the top wall of the support frame, a fixing tile rotatably installed at the bottom of the threaded rod, and side blocks fixedly installed at both the front and rear ends of the fixing tile, with the two side blocks slidably installed inside the front and rear walls of the support frame respectively.

[0010] Furthermore, a rubber pad is fixedly installed at the bottom of the fixed tile, and the rubber pad corresponds to the groove opened at the top of the cylindrical pad.

[0011] Furthermore, the drive structure includes two support side blocks fixedly installed in front of the test table, two metal rods fixedly installed between the two support side blocks, a sliding arm slidably installed on the outside of the two metal rods, a motor fixedly installed on the left side of the left support side block, a lead screw fixedly installed at the output end of the motor, the lead screw rotatably installed between the two support side blocks, and the lead screw threadedly installed inside the sliding arm.

[0012] Furthermore, a handwheel is fixedly installed on the top of the threaded rod, and the handwheel is located above the support frame.

[0013] Furthermore, four base posts are fixedly installed on the bottom of the test table, with the four base posts respectively located near the four corners of the test table.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: The cable to be tested is inserted into two support frames and placed in the groove at the top of the cylindrical pad. The cable is fixed by the compression fixing mechanism. After the cable is fixed, the electric push rod at the top of the sliding arm pushes the slider down, causing the abrasive cylinder to contact the cable and apply pressure. By observing the extension length of the electric push rod and the cable holding time, its compressive strength can be determined. Then, the drive structure runs, causing the sliding arm to move left and right, so that the abrasive cylinder slides on the top of the cable, and the abrasion resistance of the cable can be detected simultaneously.

[0022] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0023] Example 1, such as Figures 1-5 As shown, a cable testing tool includes a test table 1. Two support frames 2 are fixedly installed on the top of the test table 1. A cylindrical pad 3 is fixedly installed near the top of each of the two support frames 2. A groove is opened on the top of each of the two cylindrical pads 3. A compression fixing mechanism is provided inside each of the two support frames 2. The two compression fixing mechanisms are respectively located above the two cylindrical pads 3. A tensile and abrasion resistance testing mechanism is provided in front of the test table 1.

[0024] Specifically, the tensile and abrasion resistance testing mechanism includes a sliding arm 4 located in front of the test table 1. An electric push rod 5 is fixedly installed on the top of the sliding arm 4 and extends through its interior. A slider 6 is fixedly installed on the telescopic end of the electric push rod 5. The slider 6 is slidably installed inside the sliding arm 4. A frosting cylinder 7 is rotatably installed on the back of the slider 6. A drive structure for moving the sliding arm 4 is provided in front of the test table 1.

[0025] In use, the cable to be tested is threaded into the interior of the two support frames 2, so that the cable is in the grooves opened on the top of the two cylindrical pads 3. Then, the compression and fixing mechanism is operated to compress and fix the cable on the top of the two cylindrical pads 3. After the cable is fixed, the electric push rod 5 installed on the top of the sliding arm 4 unfolds and pushes the slider 6 down. The slider 6 drives the abrasive cylinder 7 down and contacts the cable, applying pressure to the cable. At this time, the compressive strength of the cable can be determined by observing the unfolded length of the electric push rod 5 and the time the cable holds the pressure. Afterward, the drive structure is operated to drive the sliding arm 4 to move left and right, which can drive the abrasive cylinder 7 installed on the back of the slider 6 to slide left and right on the top of the cable. At this time, the compressive strength of the cable can be tested at the same time as its abrasion resistance.

[0026] Example 2, as Figures 1-5 As shown, this embodiment is a further improvement based on embodiment 1, and its specific details are as follows:

[0027] The compression fixing mechanism includes a threaded rod 8 threadedly installed inside the top wall of the support frame 2. A fixing tile 9 is rotatably installed at the bottom of the threaded rod 8. Side blocks 10 are fixedly installed at both the front and rear ends of the fixing tile 9. The two side blocks 10 are slidably installed inside the front and rear walls of the support frame 2, respectively.

[0028] With this configuration, the fixed tile 9 is confined to the inside of the support frame 2 by the two side blocks 10. Rotating the threaded rod 8 in the forward direction can push the fixed tile 9 down, thereby squeezing and fixing the cable on the top of the cylindrical pad 3. Rotating the threaded rod 8 in the reverse direction can pull the fixed tile 9 up, at which point the cable on the top of the cylindrical pad 3 is released from fixation.

[0029] Example 3, as Figure 1 and Figure 5 As shown, this embodiment is a further improvement based on embodiment 2, and its specific details are as follows:

[0030] A rubber base pad 11 is fixedly installed at the bottom of the fixed tile 9, and the rubber base pad 11 corresponds to the groove opened at the top of the cylindrical pad 3.

[0031] With this configuration, the rubber pad 11 installed at the bottom of the fixed tile 9 contacts the cable at the top of the cylindrical pad 3, which can effectively prevent the cable from being pulled and slipping.

[0032] Example 4, as Figures 1-4 As shown, this embodiment is a further improvement based on embodiment 1, and its specific details are as follows:

[0033] The drive structure includes two support blocks 12 fixedly installed in front of the test table 1, two metal rods 13 fixedly installed between the two support blocks 12, a sliding arm 4 slidably installed on the outside of the two metal rods 13, a motor 14 fixedly installed on the left side of the left support block 12, a lead screw 15 fixedly installed on the output end of the motor 14, the lead screw 15 is rotatably installed between the two support blocks 12, and the lead screw 15 is threadedly installed inside the sliding arm 4.

[0034] With this setup, the two metal rods 13 are supported in front of the test table 1 by the two support side blocks 12. At this time, the two metal rods 13 can restrict the sliding arm 4 to slide in front of the test table 1. Then, the motor 14 drives the lead screw 15 to rotate in both directions inside the sliding arm 4, which can drive the sliding arm 4 to move left and right. The moving sliding arm 4 can then drive the slider 6 and the grinding cylinder 7 to move.

[0035] Example 5, as Figure 5 As shown, this embodiment is a further improvement based on embodiment 2, and its specific details are as follows:

[0036] A handwheel 16 is fixedly installed on the top of the threaded rod 8, and the handwheel 16 is located above the support frame 2.

[0037] This design allows the handwheel 16 to easily control the rotation of the threaded rod 8.

[0038] Example 6, as Figures 1-4 As shown, this embodiment is a further improvement based on embodiment 1, and its specific details are as follows:

[0039] Four base posts 17 are fixedly installed on the bottom of the test table 1, with the four base posts 17 located near the four corners of the test table 1.

[0040] This setup allows the testing tool to be stably supported on the ground via the installed base column 17.

[0041] Working principle:

[0042] When performing cable testing, first insert the cable to be tested into the interior of the two support frames 2, so that the cable is in the groove opened at the top of the two cylindrical pads 3. Then operate the pressing and fixing mechanism to restrict the fixing tile 9 inside the support frame 2 through the two side blocks 10 and raise and lower it. Use the handwheel 16 to operate the threaded rod 8 to rotate in the forward direction, push the fixing tile 9 down, and press and fix the cable at the top of the cylindrical pad 3. The rubber pad 11 installed at the bottom of the fixing tile 9 contacts the cable, which can effectively prevent the cable from being pulled and slipping.

[0043] After the cable is fixed, the electric push rod 5 installed on the top of the sliding arm 4 unfolds, pushing the slider 6 down. The slider 6 drives the abrasive cylinder 7 down and into contact with the cable, applying pressure to the cable. At this time, by observing the unfolded length of the electric push rod 5 and the time the cable holds, the compressive strength of the cable can be determined.

[0044] Next, the abrasion resistance test is carried out. The motor 14 drives the lead screw 15 to rotate in both directions inside the sliding arm 4, which in turn moves the sliding arm 4 left and right, thereby causing the abrasion cylinder 7 installed on the back of the slider 6 to slide left and right on the top of the cable. In this way, while the cable is being tested for compressive strength, its abrasion resistance can also be tested simultaneously.

[0045] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
