Description

Technical Field

[0001] This utility model relates to the field of electrical testing technology, and in particular to a quality inspection and screening device for power cords. Background Technology

[0002] As a key component in electrical equipment for transmitting electrical energy, the quality of power cords directly affects the safe operation of electrical equipment and the safety of users' lives and property. Substandard power cords may have problems such as excessive conductor resistance, poor insulation performance, and uneven sheath thickness. These problems can lead to safety accidents such as overheating, short circuits, and even fires during use. Therefore, strict quality testing of power cords is an important step in ensuring their safety and reliability.

[0003] Traditional power cord quality inspection relies on manual visual inspection to check for damage, scratches, and uneven coloring on the surface. However, manual inspection is subject to subjectivity, low efficiency, and fatigue. It is difficult to accurately identify subtle defects and cannot detect internal quality issues. Existing methods use instruments such as multimeters to test conductivity and withstand voltage testers to test insulation performance, but these methods often only test single parameters and cannot achieve comprehensive and rapid testing of multiple quality parameters. Moreover, for complex quality issues, such as the stranding quality of the conductors and the bonding strength between the insulation and sheath layers, these simple instruments are insufficient for effective testing and evaluation, failing to meet user needs.

[0034] Please see the appendix Figure 3 - Appendix Figure 5 The limiting mechanism 3 includes a rotating handle 302, which is located on the top of the base 1. A bidirectional threaded post 303 is rotatably connected to the rear side of the rotating handle 302. A fixing component 301 is rotatably connected to the outer wall of the bidirectional threaded post 303.

Multiple sliding components 305 are threadedly connected to the outer wall of the bidirectional threaded post 303. A clamp 306 is fixedly connected to the bottom of the sliding component 305.

[0035] Specifically, a rotating handle 302 is carefully provided at the top of the base 1. The rear side of the rotating handle 302 is rotatably connected to the bidirectional threaded post 303 through a reliable rotating structure, allowing the bidirectional threaded post 303 to rotate flexibly around a specific axis. The outer wall of the bidirectional threaded post 303 is rotatably connected to the fixing component 301, ensuring that the fixing component 301 maintains a relatively stable position when the bidirectional threaded post 303 rotates. At the middle of the outer wall of the bidirectional threaded post 303, a limiting post 304 is fixedly connected, which restricts the rotation range of the bidirectional threaded post 303 and the movement position of related components. The outer wall of the bidirectional threaded post 303 is also evenly threaded with multiple sliding components 305. When the bidirectional threaded post 303 rotates, these sliding components 305 will move along the axial direction of the bidirectional threaded post 303. Each sliding component 305 is fixedly connected to a clamp 306 at its bottom. As the sliding component 305 moves, the clamp 306 will also change position accordingly.

[0036] Please see the appendix Figure 1 - Appendix Figure 3 The transmission assembly 203 includes a roller 2031, the middle of which is fixedly connected to the outer wall of the first rotating column 202.

A sliding block 2094 is threadedly connected to the outer wall of the short threaded column 2093.

[0037] Specifically, in the mechanical structure, roller 2031 is securely fixed to the middle of the outer wall of rotating column 202 to ensure stability during operation. The outer wall of roller 2031 is connected to the transmission belt 2032 for power transmission. The meshing assembly 206 consists of multiple parts, with the front of rotating column 2061 tightly fixed to the output end of motor 205. When motor 205 starts, rotating column 2061 rotates, and the half gear 2062 fixedly connected to the middle of its outer wall rotates synchronously, meshing with the outer wall of gear frame 2063 and driving gear frame 2063 forward. The screening assembly 209 also includes several key components to perform corresponding movements. The rear side of the motor 2091 is fixedly connected to the front side of the carrier 208, providing power support for the entire screening assembly 209. The output end of the motor 2091 is fixedly connected to the bevel gear set 2092, which changes the direction of power. The rear side of the bevel gear set 2092 is fixedly connected to the short threaded column 2093. When the motor 2091 runs, the short threaded column 2093 will rotate accordingly. The outer wall of the short threaded column 2093 is threadedly connected to the sliding block 2094. Under the rotation of the short threaded column 2093, the sliding block 2094 will move along the thread direction.

[0038] Please see the appendix Figure 3 - Appendix Figure 5 The fixing component 301 includes a fixing plate 3011, the bottom of which is fixedly connected to the front and rear sides of the top of the base 1. A slide rod 3012 is fixedly connected to the middle of the fixing plate 3011. The sliding component 305 includes a slider 3051, the middle of which is threaded on the outer wall of the bidirectional threaded column 303. A slider 3052 is fixedly connected to the top of the slider 3051. A testing instrument 5 is fixedly connected to the rear side of the top of the bearing plate 204. A buzzer 6 is fixedly connected to the front side of the top of the bearing plate 204.

[0039] Specifically, the bottom of the fixing plate 3011 is firmly fixed to the front and rear sides of the top of the base 1, providing a solid support foundation for the entire structure. The middle of the fixing plate 3011 is fixedly connected to the slide rod 3012. The slide rod 3012 provides the necessary guidance for the subsequent sliding assembly 305. The slider 3051 in the sliding assembly 305 is tightly connected to the outer wall of the bidirectional threaded column 303 through its central thread. When the bidirectional threaded column 303 rotates, the slider 3051 moves along the thread direction. The top of the slider 3051 is also fixedly connected to the slider 3052. The slider 3052 cooperates with the slide rod 3012 to ensure the stability and accuracy of the sliding assembly 305 during movement. In addition, the top rear side of the support plate 204 is fixedly connected to the detection instrument 5 for real-time monitoring of the operating status of the mechanical device, while the top front side of the support plate 204 is fixedly connected to the buzzer 6. When the detection instrument 5 detects an abnormality, the buzzer 6 will sound an alarm to remind the operator to deal with it in time.

[0040] Working principle: By placing the power cord to be tested on top of the transmission belt 2032, starting the motor 201 causes the rotating column 202 at the output end to drive the roller 2031 on the outer wall to start rotating, pushing the power cord on top to the right. The motor 205 at the top controls the half gear 2062 to move up and down with the gear frame 2063 meshing on the outer wall. The data detected by the detection probe 207 at the bottom is uploaded to the detection instrument 5, so that the user controls the motor 2091 to indirectly control the screening frame 210 to slide back and forth, pushing qualified and unqualified power cords to the front and back sides. The user places them in the storage box for separate storage. This structure improves the detection speed and facilitates user operation.

[0041] By manually rotating the handle 302, the bidirectional threaded column 303 on the rear side rotates, and the slider 3051 on the outer wall moves back and forth. The two sliders 3051 move in opposite directions, and the top slider 3052 slides on the slide rod 3012, so that the bottom clamp 306 moves more smoothly towards the center, restricting the power line to be tested in the middle to a fixed range, and preventing it from deviating from the original path during the transmission of the transmission belt 2032, thus facilitating the operation of the entire device.
