[0025] Secondly, the so-called "one embodiment" or "embodiment" herein refers to a specific feature, structure or characteristic that can be included in at least one implementation manner of the present utility model. The "in one embodiment" that appears in different places in this specification does not all refer to the same embodiment, nor is it a separate or alternative embodiment that excludes other embodiments.

[0026] Embodiment 1

[0027] Refer to the figure, please refer to Figures 1-5, which is the first embodiment of the present utility model. This embodiment provides a tensile test device for plastic-coated wires, including a test platform 1, a winding and fixing mechanism 2, a fixing plate 4, and a slider 5. The winding and fixing mechanism 2 is arranged at the top of the slider 5 and the top inside the fixing plate 4. The winding and fixing mechanism 2 includes a fixing shaft 201, a winding hook 202, and a winding column 203. The fixing shaft 201 is fixedly installed at the top inside the fixing plate 4, the winding hook 202 is fixedly installed inside the fixing shaft 201, and the winding column 203 is fixedly installed at the top of the slider 5.

[0028] Specifically, a tensile moving mechanism 3 is arranged on the top of the test platform 1. The tensile moving mechanism 3 includes a driving motor 301, a support plate 302, a threaded rod 303, a slide rail 304, a scale label 305, a threaded groove 306, and a round hole 307. The fixing plate 4 is located at the left and right ends of the top of the test platform 1, and the driving motor 301 is fixedly installed at the bottom of the left surface of the fixing plate 4.

[0029] Furthermore: The fixing plate 4 is located at the left and right ends of the top of the test platform 1, providing the functions of supporting and fixing other components, such as the slide rail 304, the driving motor 301, etc. The driving motor 301 provides power, and drives the slider 5 to move along the slide rail 304 by rotating the threaded rod 303, realizing the stretching of the plastic-coated wire.

[0030] Specifically, the support plate 302 is fixedly installed at the bottom of the driving motor 301 and fixedly connected to the test platform 1. The threaded rod 303 is connected to the input end of the driving motor 301 by wire and movably connected to the inside of the fixing plate 4. The slide rail 304 is fixedly installed on the front and back of the inside of the fixing plate 4, and the slider 5 is movably connected to the surface of the slide rail 304 and threadedly connected to the threaded rod 303.

[0031] Furthermore: The support plate 302 fixes the driving motor 301 and connects it to the test platform 1, ensuring the stability and support force of the motor. The threaded rod 303 is connected to the output shaft of the driving motor 301, and drives the slider 5 to move along the slide rail 304 by rotation, realizing the stretching of the plastic-coated wire. The slide rail 304 is fixed inside the fixing plate 4, providing a track for the linear movement of the slider 5, ensuring the linear movement of the slider 5 during the stretching process.

[0032] Specifically, the scale labels 305 are pasted on the front and back of the top of the test platform 1. The threaded groove 306 is opened inside the slider 5, and the threaded groove 306 is threadedly connected to the threaded rod 303. The round holes 307 are opened at the left and right ends inside the slider 5, and the round holes 307 are movably connected to the slide rail 304.

[0033] Furthermore: scale labels 305 are pasted on the front and back of the test platform 1 to intuitively display the moving distance of the slider 5, so that the operator can monitor the stretching process. The threaded groove 306 is opened on the inner side of the slider 5 and is threadedly connected to the threaded rod 303, so that the rotation of the threaded rod 303 can be converted into the linear motion of the slider 5. It is opened on the left and right ends of the inner side of the slider 5 and is movably connected to the slide rail 304 to ensure the smooth sliding of the slider 5 on the slide rail 304.

[0034] Specifically, a tension sensor 6 is fixedly connected to the top of the slider 5, and the tension sensor 6 is fixedly connected to the wrapping column 203. A data acquisition and analyzer 7 is fixedly installed on the bottom of the test platform 1. A display 8 is fixedly installed on the front of the data acquisition and analyzer 7. An inspection panel 9 is fixedly connected to the back of the data acquisition and analyzer 7. A controller 10 is arranged on the left side of the data acquisition and analyzer 7.

[0035] Further: the tension sensor 6 is used to monitor the tension that the plastic-coated wire is subjected to during the stretching process in real time, and convert these force signals into electrical signals for data collection and analysis. The data acquisition and analyzer 7 is responsible for collecting data from the tension sensor 6, and processing and analyzing these data. It can convert the original force signal into readable digital information, and store and analyze it. The display 8 is used to display key data such as the force value and stretching distance during the stretching process in real time, so that the operator can intuitively monitor the test progress and results. The controller 10 is used to input and adjust test parameters, such as stretching speed, target stretching distance, etc., and control the operation of the drive motor 301 to achieve precise control of the stretching process.

[0036] Specifically, the four sides of the bottom of the data acquisition and analysis device 7 are fixedly connected with support legs 11 , the inner side of the support legs 11 is fixedly connected with a connecting bracket 12 , and the bottom of the support legs 11 is fixedly connected with an anti-slip pad 13 .

[0037] Furthermore: the support legs 11 provide stable support for the data acquisition and analyzer 7. The distribution of multiple support legs 11 can ensure that the data acquisition and analyzer 7 remains horizontal and stable during the test, avoiding inaccurate data collection due to vibration or external force. The connecting bracket 12 strengthens the structural stability between the support legs 11 to ensure the firmness and durability of the entire support system. The connecting bracket 12 may be made of rigid material to provide additional structural strength to prevent the support legs 11 from deforming or breaking when subjected to force.

[0038] Specifically, a flashing light 14 is fixedly connected to the left end of the right side surface of the data acquisition and analysis device 7 , and a buzzer 15 is fixedly connected to the right end of the right side surface of the data acquisition and analysis device 7 .

[0039] Furthermore: The main function of the flashing light 14 is to provide visual signals during the test, usually used to indicate specific states or warnings. When the test reaches the preset force value, stretching distance or other key parameters, the flashing light 14 may start to flash to attract the attention of the operator, prompting them to pay attention to the current test state or possible measures to be taken. The buzzer 15 is used to provide auditory signals during the test. The buzzer 15 is usually used to issue alarms or notifications. For example, when the test is completed, an abnormal situation occurs or an emergency stop is required, the buzzer 15 will emit a sound signal to ensure that the operator can hear it in time and make a response.

[0040] Working principle:

[0041] When in use, first confirm that the power connection of the device is correct, and turn on the power of the data acquisition and analyzer 7 to initialize the system. Check whether the display 8 is displaying the interface normally, and ensure that the controller 10, the flashing light 14 and the buzzer 15 are all in normal working conditions. Fix one end of the plastic-coated wire to be tested on the winding hook 202 at the inner top of the fixed plate 4, and the other end bypasses the winding column 203 on the top of the slider 5, and ensure that it is wound and fixed. Input parameters such as the required stretching speed and distance through the controller 10. Through the driving motor 301, adjust the initial position of the slider 5 on the threaded rod 303 and the slide rail 304 to ensure that the plastic-coated wire is in a slightly tensioned state before starting the stretching, but no substantial stretching is carried out. Start the driving motor 301 to make the slider 5 move along the slide rail 304, thereby stretching the plastic-coated wire attached to the slider 5. Observe the scale label 305 and monitor the extension of the plastic-coated wire. At the same time, the data acquisition and analyzer 7 will record the stretching force and stretching distance in real time. During the stretching process, the force sensor 6 will continuously monitor and convert the force data and send it to the data acquisition and analyzer 7. The data acquisition and analyzer 7 will process the collected data and display the stretching force and extension distance data on the display 8 in real time. According to the preset parameters or the observed data, when the set stretching limit is reached or the sample breaks, the controller 10 will instruct the driving motor 301 to stop running, collect the final data, use the display 8 to show the final test results, cut off the power, remove the tested plastic-coated wire, clean and check each component of the device, and prepare for the next test.

[0042] In summary, the fixed shaft 201, the winding hook 202, and the winding column 203 contained inside the winding and fixing mechanism 2 can enable the device to provide a hanging and winding point during use, so that the plastic-coated wire can be firmly fixed on the test device, ensuring its stability during the stretching process, maintaining the straightness of the plastic-coated wire, and at the same time facilitating the installation and disassembly of the plastic-coated wire, so as to quickly replace the specimen for multiple tests, improve the test efficiency, reduce the operation time. The driving motor 301, the support plate 302, the threaded rod 303, the slide rail 304, the scale label 305, the threaded groove 306, and the round hole 307 contained inside the stretching and moving mechanism 3 can enable the device to achieve precise control of the stretching speed of the plastic-coated wire, stable linear motion, adjustable stretching distance, fixation of the slider 5, structural support, and convenience for maintenance and adjustment during use, providing the necessary operation convenience and test accuracy for the stretching test of the plastic-coated wire.
