[0002] Wires and cables are wire products used to transmit electrical (magnetic) energy, information and realize electromagnetic energy conversion. They refer to insulated cables, one or more insulated wire cores, and their respective possible coverings, overall protective layers and outer sheaths. Cables may also have additional uninsulated conductors.

[0003] Before use, existing cables typically require various tests on their outer insulation layer to ensure its quality. Among these tests is tensile strength testing. This involves manually clamping both ends of a cut section of insulation to two clamping blocks. Using a power source such as a cylinder or motor, the blocks are pulled apart, and testing instruments are used to observe the tensile force required for the insulation to break. During this breakage, fragments are ejected, generating significant impact that can injure workers or glass objects in the work environment. To prevent such injuries from broken insulation fragments, this invention proposes a performance testing device for optical storage straight-line flexible cables. Summary of the Invention

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Please see Figures 1-6 In this embodiment of the invention, a performance testing device for optical storage straight flexible cable includes a workbench 1, a drive motor 2, and a transmission mechanism 6 installed inside the workbench 1. The transmission mechanism 6 includes movable blocks 601 symmetrically arranged at the top of the workbench 1 and extending into the interior of the workbench 1. A first transparent protective plate 3 and a second transparent protective plate 4 extending into the interior of the workbench 1 are provided on both sides of the movable blocks 601. The transmission mechanism 6 also includes a lead screw 602 connected to the output end of the drive motor 2 and extending into the workbench 1. The movable block 601 is sleeved on the outer wall of the lead screw 602. The transmission mechanism 6 also includes a chain 603 sleeved on the outer wall of the lead screw 602 via a sprocket. The other end of the chain 603 is sleeved on the inner side via a sprocket with a rotating rod 604. The transmission mechanism 6 also includes a first rack 607 and a second rack 610 respectively fixed to the outer wall of one side of the first transparent protective plate 3 and the second transparent protective plate 4; As the movable block 601 moves away from another movable block 601, it can drive the first transparent protective plate 3 and the second transparent protective plate 4 to move upward. A pressing mechanism 7 is provided outside the first transparent protective plate 3 and extends into the workbench 1. The pressing mechanism 7 includes a fifth spur gear 701 that is fixedly connected to the outer wall of the rotating rod 604. The pressing mechanism 7 also includes a clamping block 709 installed outside the movable block 601 and extending into the interior of the movable block 601. The pressing mechanism 7 also includes a movable rod 707 that extends from the outside of the top of the movable block 601 through the first transparent protective plate 3, the clamping block 709 and into the interior of the first transparent protective plate 3. A pressing rod 706 is sleeved on the outer wall of the movable rod 707. A pressing ring 705 is fixedly connected to the bottom end of the pressing rod 706. A transmission rod 704 is hinged to the bottom end of the pressing ring 705. A detection instrument 5 is connected to the outer wall of a movable block 601, and one end of the detection instrument 5 is fixedly connected to the outer wall of a clamping block 709.

[0019] In this embodiment: When using this device, an upward pulling force is applied to the movable rod 707 exposed at the top of the movable block 601, causing the movable rod 707 to separate the clamping block 709 from the mating block on the outer wall of the movable block 601. The two ends of the insulating layer to be clamped are placed between the two clamping blocks 709 and the mating block, respectively. Under the elastic component of the pressing mechanism 7, the clamping block 709 is reset, completing the pre-connection of the clamping of the insulating layer. By starting the drive motor 2, the drive motor 2 will drive the lead screw 602 at the output end of the drive motor 2 to rotate. The rotation of the lead screw 602 will drive the movable block 601 to move along the thread on the outer wall of the lead screw 602, causing the two movable blocks 601 to move away from each other, while simultaneously driving the chain 603 to drive the transmission. Rotating rod 604 rotates, which drives the transmission components of transmission mechanism 6 to work, raising the first transparent protective plate 3 and the second transparent protective plate 4 to protect the staff and prevent the flying of fragments caused by the breakage of the insulation layer. During the rotation of rotating rod 604, it also drives the fifth spur gear 701 to rotate. The rotation of the fifth spur gear 701 drives the transmission component of pressing mechanism 7 to work, so that pressing ring 705 drives pressing rod 706 to move downward along the outer wall of movable rod 707. Pressure is transmitted through the elastic component between movable rod 707 and pressing rod 706, so that the mating block of clamping block 709 and the outer wall of movable block 601 are connected more tightly, increasing the clamping force on the insulation layer.

[0020] Please refer to this carefully. Figure 2-6 The transmission mechanism 6 also includes a first spur gear 605 fixedly connected to the outer wall of the rotating rod 604. The first spur gear 605 is located at one end of the fifth spur gear 701. A second spur gear 606 meshes with one side of the outer wall of the first spur gear 605. A first rack 607 is fixed to the outer wall of the first transparent protective plate 3. A third spur gear 608 meshes with the other side of the outer wall of the first spur gear 605. A fourth spur gear 609 meshes with the outer wall of the third spur gear 608. A second rack 610 meshes with the outer wall of the fourth spur gear 609. The second rack 610 is fixedly connected to the outer wall of the second transparent protective plate 4. The second spur gear 606, the third spur gear 608, and the fourth spur gear 609 are all rotatably connected to the inner wall of the workbench 1. The pressing mechanism 7 also includes a sixth spur gear 702 meshing above the fifth spur gear 701. One end of the sixth spur gear 702 is fixedly connected to a positioning rod 703, and the outer wall of the positioning rod 703 is sleeved with the inner side of one end of the transmission rod 704. A second spring 710 is sleeved on the outer wall of the movable rod 707 above the clamping block 709, and a first spring 708 is sleeved on the outer wall of the movable rod 707 below the pressing rod 706. One end of the pressing ring 705 is connected to a connecting rod 711, and a second spring 710 is sleeved on the outer wall of the connecting rod 711. A sleeve rod 712 is sleeved on the outer wall of the connecting rod 711. The outer wall of the worktable 1 is provided with a groove that matches the lateral movement trajectory of a movable block 601, and another movable block 601 is fixedly connected to the inner wall of the worktable 1.

[0021] In this embodiment: by applying an upward pulling force to the movable rod 707 exposed at the top of the movable block 601, the movable rod 707 causes the clamping block 709 to separate from the mating block on the outer wall of the movable block 601. The two ends of the insulating layer to be clamped are placed between the two clamping blocks 709 and the mating block, respectively. Under the elastic force of the second spring 710, which is an elastic component of the pressing mechanism 7, the clamping block 709 is reset, completing the pre-connection of the clamping of the insulating layer. By starting the drive motor 2, the drive motor 2 will rotate the lead screw 602 at the output end of the drive motor 2. When the lead screw 602 rotates, it drives the movable block 601 to move along the thread on the outer wall of the lead screw 602, causing the two movable blocks 601 to move away from each other. At the same time, it drives the chain 603 to drive the rotating rod 604 to rotate. The rotation of the rotating rod 604 drives the first spur gear 605, which is the transmission component of the transmission mechanism 6, to rotate. The rotation of the first spur gear 605 drives the second spur gear 606 and the third spur gear 608 to rotate. The rotation of the second spur gear 606 transmits the thrust to the first rack 607, causing the first rack 607 to move the first transparent protective plate 3 upward. The rotation of the third spur gear 608 will drive the fourth spur gear 609 to rotate. The rotation of the fourth spur gear 609 will transmit the thrust to the second rack 610, causing the second transparent protective plate 4 to move upward. This will lift the first transparent protective plate 3 and the second transparent protective plate 4, protecting the workers from flying fragments caused by the breakage of the insulation layer. During the rotation of the rotating rod 604, it will also drive the fifth spur gear 701 to rotate. The rotation of the fifth spur gear 701 will drive the sixth spur gear 702, which is the transmission component of the pressing mechanism 7, and the fixed gear 701. When the positioning rod 703 rotates, the transmission rod 704 will make a circular motion along the rotation trajectory of the positioning rod 703. When one end of the transmission rod 704 moves downward, the other end of the transmission rod 704 will also move downward, thereby pulling the pressing ring 705 downward. This causes the pressing ring 705 to drive the pressing rod 706 to move downward along the outer wall of the movable rod 707. The pressure is transmitted through the elastic component between the movable rods 707, making the connection between the clamping block 709 and the mating block on the outer wall of the movable block 601 tighter and increasing the clamping force on the insulation layer.

[0022] Please refer to this carefully. Figure 2-6 The movable block 601 has an internal movable groove that matches the movement trajectory of another clamping block 709, movable rod 707, and pressing rod 706. The movable block 601 also has an internal vertical groove that matches the vertical movement of pressing rod 706 and movable rod 707. The outer wall of the movable block 601 has a mating block corresponding to the clamping block 709. The outer walls of the mating block and the clamping block 709 have stripes to increase friction. Inside a movable block 601 connected to the testing instrument 5, there is a movable groove that matches the movement trajectory of another clamping block 709, movable rod 707, and pressing rod 706, to provide movement space for the other clamping block 709 connected to the testing instrument 5. Inside the movable block 601, there is also a vertical groove that matches the vertical movement of the pressing rod 706 and movable rod 707.

[0023] In this embodiment: when the movable block 601 moves under the rotation of the lead screw 602, the movable block 601 will also drive the transmission rod 704 to move laterally along the outer wall of the positioning rod 703. The lateral movement of the transmission rod 704 will not affect the transmission rod 704 receiving the pulling force from the positioning rod 703.

[0024] Please refer to this carefully. Figure 2-6 The outer wall of the movable block 601 is provided with a mating block corresponding to the clamping block 709. The outer walls of the mating block and the clamping block 709 are provided with stripes to increase friction. The position where the positioning rod 703 contacts the sixth spur gear 702 is far from the center position of the sixth spur gear 702. The inner wall of the movable block 601 is provided with a thread that matches the outer wall of the lead screw 602. The inner wall of the worktable 1 is provided with a groove that matches the vertical movement trajectory of the first transparent protective plate 3 and the second transparent protective plate 4.

[0025] In this embodiment: with this structure, when the movable block 601 moves, it will synchronously drive the connecting rod 711 to move along the inner cavity of the sleeve rod 712. The insulating layer clamped between the clamping blocks 709 will be subjected to the tension generated by the movement of the movable block 601, while the other clamping block 709 will be subjected to the force and move laterally a certain distance along the interior of the other movable block 601, transmitting the force to the detection instrument 5, thereby observing the tension on the insulating layer.
