Description

Technical Field

[0001] This utility model belongs to the field of power cord testing technology, specifically relating to a tensile and abrasion-resistant power cord testing device. Background Technology

[0002] In modern electronic equipment and power transmission, power cords are critical connecting components, and their quality directly affects the safety and stability of the equipment. With the diversification of electronic equipment usage scenarios, the requirements for the tensile strength and abrasion resistance of power cords are constantly increasing. Traditional tensile strength testing of power cords typically uses manual pulling or simple clamps with spring scales, which is not only inefficient but also difficult to precisely control the testing force and time, failing to realistically simulate the stress conditions of the power cord during actual use. Abrasion resistance testing, on the other hand, lacks dedicated testing tools, resulting in inconsistent testing standards and difficulties in quantitative assessment. Furthermore, for power cord leakage safety testing, existing technologies often separate tensile strength, abrasion resistance, and leakage testing, increasing the complexity of the testing process and potentially leading to inaccurate test results due to repeated disassembly and reassembly of the power cord. Utility Model Content

[0003] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a tensile and wear-resistant power cord testing device, including a testing platform, on which a pulling mechanism and a leakage current detection mechanism are provided. The pulling mechanism includes a tension spring, a rear clamping mechanism, a front clamping mechanism, and a telescopic drive mechanism arranged in sequence. The front clamping mechanism and the rear clamping mechanism have the same structure. The front clamping mechanism includes a lower clamping plate and an upper clamping plate. A screw is fixedly connected to both ends of the lower clamping plate, and through holes are provided at both ends of the upper clamping plate for the screw to move through. A locking nut is threadedly connected to the through hole. One end of the tension spring is fixedly connected to the detection platform, and the other end is fixedly connected to the lower clamping plate of the rear clamping mechanism. The telescopic drive mechanism drives the lower clamping plate of the front clamping mechanism to move. The leakage current detection mechanism includes two fixed rods respectively fixed on the detection platform. The fixed rods are provided with a through hole for inserting one end of the power cord. The fixed rods are provided with a threaded hole that connects to the through hole. A locking screw is threadedly connected to the threaded hole. A conductive sheet is provided in the through hole. A water tank is provided between the two fixed rods. The water tank is filled with an electrolyte solution.

[0004] As a preferred embodiment of the above technical solution, a boss is provided between the front clamping mechanism and the rear clamping mechanism. The boss is fixed on the detection table, and the height of the upper surface of the boss is higher than the height of the front clamping mechanism and the height of the rear clamping mechanism, respectively.

[0008] As a preferred embodiment of the above technical solution, the water tank is provided with a conductive plate, the lower end of which is located at the bottom of the water tank, and the upper end of which extends out of the water tank.

[0009] The beneficial effects of this utility model are as follows: The tensile and abrasion-resistant power cord testing device of this utility model can simultaneously complete the tensile, abrasion, and leakage safety tests of power cords, greatly simplifying the testing process and significantly improving testing efficiency. Specifically, the front and rear clamping mechanisms of the pulling mechanism, in conjunction with the telescopic drive mechanism, can precisely control the pulling force and stroke, realistically simulating the actual stress on the power cord; the setting of the boss and sandpaper enables standardized and quantifiable abrasion resistance testing. The leakage detection mechanism utilizes an electrolyte solution and a conductive plate to effectively test the insulation performance of the power cord. Furthermore, the design of the sliding sleeve and sliding rod ensures the stability of the clamping mechanism's movement, while the electric push rod or cylinder provides a reliable power source, ensuring high accuracy and stability of the test results.

[0013] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components.

[0014] Tensile and abrasion resistant power cord testing device, such as Figure 1 As shown, the device includes a testing platform 1, which is equipped with a tension mechanism and a leakage current detection mechanism. The tension mechanism includes a tension spring 2, a rear clamping mechanism, a front clamping mechanism, and a telescopic drive mechanism 3 arranged sequentially. The front clamping mechanism and the rear clamping mechanism have the same structure. The front clamping mechanism includes a lower clamping plate 4 and an upper clamping plate 5. Screws 6 are fixedly connected to both ends of the lower clamping plate 4. Through holes for the screws 6 to pass through are provided at both ends of the upper clamping plate 5. After the screws 6 pass through the through holes, they are threadedly connected to a locking nut 7. One end of the tension spring 2 is fixed. The detection platform 1 is connected to the lower clamping plate 4 of the rear clamping mechanism, and the telescopic drive mechanism 3 drives the lower clamping plate 4 of the front clamping mechanism to move. The leakage current detection mechanism includes two fixed rods 8 fixed on the detection platform 1. The fixed rods 8 are provided with a threaded hole 9 for inserting one end of the power cord. The fixed rods 8 are provided with a threaded hole 10 communicating with the threaded hole 9. The threaded hole 10 is threadedly connected to a locking screw 11. A conductive sheet 13 is provided in the threaded hole 9. A water tank 14 is provided between the two fixed rods 8. The water tank 14 is filled with an electrolyte solution. The electrolyte solution is preferably a salt water solution with a certain concentration, but other conductive liquids can also be selected. The two ends of the power cord are clamped and fixed by the front clamping mechanism and the rear clamping mechanism, respectively. The telescopic drive mechanism 3 drives the front clamping mechanism to move, and with the help of the tension spring 2, the power cord is repeatedly stretched. After being stretched a specific number of times, the power cord is removed, and the insulation at both ends is stripped. It is then inserted into the threaded hole 9, and the locking screw 11 is used to tighten the power cord, electrically connecting it to the conductive plate 13. One conductive plate 13 is connected to the power source. A multimeter is used to test the other conductive plate 13, measuring the resistance and current of the power cord to determine the change in its internal conductivity after stretching. The middle section of the power cord is then immersed in the electrolyte solution in the water tank 14, and the electrolyte solution is measured to determine if the insulation performance of the power cord's outer sheath has changed after stretching.

[0015] Furthermore, a boss 15 is provided between the front clamping mechanism and the rear clamping mechanism. The boss 15 is fixed on the testing table 1. The height of the upper surface of the boss 15 is higher than the height of the front clamping mechanism and the height of the rear clamping mechanism, respectively. The upper surface of the boss 15 is smoothly designed. The boss 15 applies a certain tension to the power cord, thereby improving the testing effect on the tensile strength of the power cord.

[0016] Furthermore, the boss 15 is covered with sandpaper, which is fixed to the boss 15 by several screws. The boss 15 has several screw holes 16 around its perimeter for the screws to be screwed in. When it is necessary to test the abrasion resistance of the power cord, sandpaper is placed on the upper surface of the boss 15. The sandpaper abrades the surface of the power cord as it moves back and forth, thus testing the abrasion resistance of the power cord. The sandpaper can be replaced periodically by loosening the screws.

[0017] Furthermore, several sliding sleeves 17 are fixedly connected to the lower clamping plate 4, and sliding rods 18 are provided inside the sliding sleeves 17. The sliding rods 18 are fixedly connected to the testing platform 1. The cooperation between the sliding rods 18 and the sliding sleeves 17 makes the front clamping mechanism and the rear clamping mechanism move smoothly and in a fixed direction, ensuring that the tension on the power cord is stable and the test results are more accurate.

[0018] Furthermore, the telescopic drive mechanism 3 is an electric push rod. The electric push rod drives the lower clamping plate 4 of the front clamping mechanism to move back and forth, cooperating with the tension spring 2 to repeatedly pull the power cord. Through the electric push rod, the frequency and number of times the power cord is pulled can be precisely controlled. The tension spring 2 is detachably connected to the detection platform 1 and the lower clamping plate 4 of the rear clamping mechanism, so that by replacing the tension spring 2 with different specifications, the tension on the power cord can be adjusted.

[0019] Furthermore, a conductive plate 19 is provided in the water tank 14, with its lower end located at the bottom of the water tank 14 and its upper end extending out of the water tank 14. When checking whether the power cord is leaking current, a test pen or other tools can be used to check whether the conductive plate 19 is energized, avoiding the need to insert handheld instruments into the water tank to contact the electrolyte solution, thus improving the safety of the testing process.

It should be understood that those skilled in the art can make many modifications and variations based on the concept of the present invention without creative effort.
