Description

Technical Field

[0001] This utility model relates to the field of audio adapter cable processing technology, and in particular to a tensile strength testing device for audio adapter cable processing. Background Technology

[0002] Audio adapter cables are cables used to connect different audio devices and enable audio signal transmission and conversion. In daily use, audio adapter cables may be subjected to various tensile forces. To ensure the quality of audio adapter cables, tensile testing equipment is often used to test them during production.

[0003] Existing technologies, such as the utility model patent with publication number CN211553580U, disclose a wire tensile strength testing device. The device's housing is equipped with a fixed clamp and a movable clamp for holding and fixing the wire. The two ends of the wire to be tested are fixed to the two clamps, and then the movable clamp moves away from the fixed clamp via a drive assembly, thereby performing tensile strength testing on the wire. During this process, different modes and speeds of tensile strength testing can be performed through an internal control system to meet testing needs. This wire tensile strength testing device has a simple structure and is easy to operate. The two clamps can adopt different structures as needed, and the drive assembly can use a lead screw for driving, thereby improving working stability and testing accuracy.

[0004] Currently, most tensile testing devices display their test data through intelligent equipment, which increases the testing cost of adapter cables and hinders the widespread use of the equipment. In addition, the equipment uses clamps to hold the adapter cables, resulting in uneven stress on the surface of the adapter cables during the testing process, which can easily lead to damage and affect the accuracy of the test data. These issues need to be addressed. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing tensile testing devices, which often rely on intelligent devices to display their test data, thus increasing the testing cost of adapter cables and hindering their widespread use. Additionally, the use of clamps to hold the adapter cables during testing results in uneven stress on the cable surface, making it prone to breakage and affecting the accuracy of the test data. Therefore, this invention proposes a tensile testing device for audio adapter cable processing.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a tensile testing device for audio adapter cable processing, comprising a table, a support leg fixedly connected to the lower surface of the table, and a testing mechanism provided on the upper surface of the table. The testing mechanism includes a guide rail, a positioning component, and a testing component. The guide rail is fixedly connected to the upper surface of the table, a slider is slidably connected to the inner wall of the guide rail, and a mounting ring is fixedly connected to the upper surface of the slider. The positioning component is located inside the mounting ring and includes an air bladder. The air bladder is fixedly connected to the inner wall of the mounting ring, a conduit is fixedly connected to the input end of the air bladder, one end of the conduit penetrates the mounting ring, and an air pump is fixedly connected to the end of the conduit away from the air bladder. The testing component is located on the upper surface of the platform. The testing component includes a cylinder, the output end of which is fixedly connected to a connecting block. A stop block is fixedly connected to the surface of the connecting block. This solution uses an airbag to fix the audio adapter cable, which can apply pressure evenly from all sides to ensure that the cable will not loosen or shift during the test. This solution has a simple structure and low cost, making it easy to widely use. This solution can be used for tensile testing of audio adapter cables of different sizes and strength requirements, and can quickly understand the test results without the need for complex measuring instruments, thus improving the working efficiency of the equipment. At the same time, this solution uses an airbag to clamp the adapter cable, reducing the possibility of damage due to uneven force on the surface of the adapter cable, and ensuring the accuracy of the test data.

[0007] Preferably, there are two mounting rings and two sliders, which are mirror images of each other. The two ends of the audio adapter cable to be tested are placed in the two mounting rings respectively. The air pump is started, and the air pump inflates the air bag through the conduit. The air bag expands and evenly squeezes the two ends of the audio adapter cable from all sides, firmly fixing it in the mounting ring.

[0008] Preferably, a spring is fixedly connected to the side of the two sliders that are close to each other, which can pull the two sliders closer to each other to ensure the normal use of the device.

[0009] Preferably, a mounting bracket is fixedly connected to the upper surface of the tabletop, and a sleeve is fixedly connected to the lower surface of the mounting bracket, with the air pump installed in the sleeve.

[0010] Preferably, a limiting frame is fixedly connected to one side of the mounting bracket, and the end of the limiting frame away from the mounting bracket is sleeved on the guide tube.

[0011] Preferably, guide plates are fixedly connected to the sides of the two mounting rings that are close to each other. One end of the abutment is inserted into the guide plate. The cross-section of the abutment is trapezoidal. When the cylinder is activated, the output end of the cylinder pushes the connecting block and the abutment forward. One end of the abutment is inserted into the guide plate and pushes the slider and mounting ring to the sides to displace. The spring is deformed by force. As the cylinder continues to push, the tension gradually increases, simulating the tension that the audio adapter cable may be subjected to in actual use.

[0012] Preferably, a sliding sleeve is fixedly connected to the lower surface of the abutment, a guide rod is fixedly connected to one side of the guide rail, and the end of the guide rod away from the guide rail is fixedly connected to the table surface. The sliding sleeve slides on the surface of the guide rod. A scale groove is provided on the upper surface of the abutment. The scale groove on the upper surface of the abutment can intuitively display the elongation of the wire under tension. The operator can quickly understand the test results by observing the scale groove without using complicated measuring instruments.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this invention, the two ends of the audio adapter cable to be tested are placed in two mounting rings respectively. The air pump is started, and air is pumped into the air chamber through the conduit. The air chamber expands, evenly squeezing the two ends of the audio adapter cable from all sides, firmly fixing it within the mounting rings. The cylinder is then activated, and its output pushes the connecting block and the stop block forward. One end of the stop block inserts into the guide plate and pushes the slider and mounting ring to the sides, causing the spring to deform under pressure. As the cylinder continues to push, the tension gradually increases, simulating the tension that the audio adapter cable may experience in actual use. The process ends when the audio adapter cable breaks. By closing the air pump and cylinder and observing the graduated groove, the movement distance of the stop block can be intuitively understood, thereby inferring the elongation of the audio adapter cable under tensile force and determining whether it meets quality requirements. This solution has a simple structure and low cost, making it easy to widely use. This solution can be used for tensile testing of audio adapter cables of different sizes and strength requirements, and quickly understand the test results without the need for complex measuring instruments, thus improving the working efficiency of the equipment. At the same time, this solution uses an airbag to clamp the adapter cable, reducing the possibility of damage due to uneven force on the surface of the adapter cable and ensuring the accuracy of the test data.

The testing mechanism 3 includes a guide rail 31, a positioning component 33, and a testing component 34. The guide rail 31 is fixedly connected to the upper surface of the table 1, and a slider 35 is slidably connected to the inner wall of the guide rail 31. A mounting ring 32 is fixedly connected to the upper surface of the slider 35. The positioning component 33 is located inside the mounting ring 32 and includes an airbag 331. The airbag 331 is fixedly connected to the inner wall of the mounting ring 32, and a conduit 332 is fixedly connected to the input end of the airbag 331. One end of the conduit 332 passes through the mounting ring 32, and an air pump 333 is fixedly connected to the end of the conduit 332 away from the airbag 331. The detection component 34 is located on the upper surface of the table 1. The detection component 34 includes a cylinder 343. The output end of the cylinder 343 is fixedly connected to a connecting block 345. A stop block 342 is fixedly connected to the surface of the connecting block 345. This solution uses an airbag 331 to fix the audio adapter cable, which can apply pressure evenly from all sides to ensure that the cable will not loosen or shift during the test. This solution has a simple structure and low cost, and is easy to use. This solution can be used for tensile testing of audio adapter cables of different sizes and strength requirements, and can quickly understand the test results without the need for complex measuring instruments, thus improving the working efficiency of the equipment. At the same time, this solution uses an airbag 331 to clamp the adapter cable, reducing the possibility of damage due to uneven force on the surface of the adapter cable, and ensuring the accuracy of the test data.

[0023] In this embodiment, there are two mounting rings 32 and two sliders 35, which are mirror images of each other. The two ends of the audio adapter cable to be tested are placed in the two mounting rings 32 respectively. The air pump 333 is started, and the air pump 333 inflates the air bag 331 through the conduit 332. The air bag 331 expands and evenly squeezes the two ends of the audio adapter cable from all sides, firmly fixing it in the mounting ring 32.

[0024] Specifically, a spring 36 is fixedly connected to the side of the two sliders 35 that are close to each other, which can pull the two sliders 35 closer to each other to ensure the normal use of the equipment.

[0025] Specifically, a mounting bracket 334 is fixedly connected to the upper surface of the tabletop 1, and a sleeve 335 is fixedly connected to the lower surface of the mounting bracket 334. An air pump 333 is installed in the sleeve 335.

[0026] Specifically, a limiting bracket 336 is fixedly connected to one side of the mounting bracket 334, and the end of the limiting bracket 336 away from the mounting bracket 334 is sleeved on the conduit 332.

[0027] In this embodiment: guide plates 37 are fixedly connected to the sides of the two mounting rings 32 that are close to each other. One end of the abutment block 342 is inserted into the guide plate 37. The cross-section of the abutment block 342 is trapezoidal. The cylinder 343 is activated. The output end of the cylinder 343 pushes the connecting block 345 and the abutment block 342 forward. One end of the abutment block 342 is inserted into the guide plate 37 and pushes the slider 35 and the mounting ring 32 to the sides to displace. The spring 36 is deformed by force. As the cylinder 343 continues to push, the tension gradually increases, simulating the tension that the audio adapter cable may be subjected to in actual use.

[0028] Specifically, a sliding sleeve 344 is fixedly connected to the lower surface of the abutment block 342, and a guide rod 341 is fixedly connected to one side of the guide rail 31. The end of the guide rod 341 away from the guide rail 31 is fixedly connected to the table surface 1. The sliding sleeve 344 slides on the surface of the guide rod 341. A scale groove 346 is provided on the upper surface of the abutment block 342. The scale groove 346 on the upper surface of the abutment block 342 can intuitively display the elongation of the wire under tension. The operator can quickly understand the test results by observing the scale groove 346 without using complicated measuring instruments.

[0029] Working principle: Place both ends of the audio adapter cable to be tested into the two mounting rings 32 respectively. Start the air pump 333, which inflates the air bag 331 through the conduit 332. The air bag 331 expands, evenly squeezing both ends of the audio adapter cable from all sides, firmly fixing it in the mounting rings 32. Start the cylinder 343. The output end of the cylinder 343 pushes the connecting block 345 and the abutment block 342 forward. One end of the abutment block 342 inserts into the guide plate 37 and pushes the slider 35 and the mounting ring 32 to the sides, causing the spring 36 to deform under force. As the cylinder 343 continues to push, the tension gradually increases, simulating the tension that the audio adapter cable may experience in actual use. In this case, after the audio adapter cable breaks, the air pump 333 and cylinder 343 are turned off. By observing the scale groove 346, the movement distance of the stop block 342 can be intuitively understood, and the elongation of the audio adapter cable under tensile force can be inferred, thereby determining whether it meets the quality requirements. This solution has a simple structure and low cost, making it easy to widely use. This solution can be used for tensile testing of audio adapter cables of different sizes and strength requirements, and the test results can be quickly understood without the need for complex measuring instruments, thus improving the working efficiency of the equipment. At the same time, this solution uses an airbag 331 to clamp the adapter cable, reducing the possibility of damage due to uneven force on the surface of the adapter cable, and ensuring the accuracy of the test data.
