Description

Technical Field

[0001] This utility model belongs to the field of optical cable technology, specifically relating to an optical cable torsion testing device. Background Technology

[0002] Optical cables are manufactured to meet optical, mechanical, or environmental performance specifications. They are communication cable assemblies that use one or more optical fibers placed in a sheath as the transmission medium and can be used individually or in groups. Optical cables are mainly composed of optical fibers (glass filaments as thin as a hair), plastic protective sheaths, and plastic outer sheaths. An optical cable is a communication line that uses a certain number of optical fibers arranged in a certain way to form a cable core, which is covered with a sheath, and some also have an outer protective layer, to realize the transmission of optical signals. Before being put into use, optical cables need to be twisted.

[0003] Existing optical cable torsion testing devices include two sets of clamps, one of which is connected to a drive mechanism, while the other clamp is fixed. The clamp connected to the other clamp is driven to rotate by a power component to perform a torsion test on the optical cable. However, since the position of the other clamp is fixed, the device can only perform torsion tests on optical cables of a specified length. When the cable is too long, it needs to be cut, and when the cable is too short, the test cannot be performed, which limits the scope of application of the device. Therefore, we provide an optical cable torsion testing device. Utility Model Content

[0004] The purpose of this invention is to provide an optical cable torsion testing device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fiber optic cable torsion testing device, comprising a base box, a first motor fixedly installed on the right side of the inner cavity of the base box, a lead screw fixedly connected to the output end of the first motor, a sliding sleeve threadedly connected to the surface of the lead screw, a connecting column fixedly connected to the top of the sliding sleeve, a first disc fixedly connected to the top of the connecting column, an L-shaped frame fixedly connected to the bottom of the right side of the base box, a second motor fixedly installed on the inner side of the L-shaped frame, a main rotating rod fixedly connected to the output end of the second motor, a main gear fixedly connected to one end of the main rotating rod, a secondary gear meshing with the surface of the main gear, a secondary rotating rod fixedly connected to the inner wall of the secondary gear, a second disc fixedly connected to one end of the secondary rotating rod, a positioning box fixedly connected to one side of both the first and second discs, an electric telescopic rod fixedly connected to the top of the positioning box, and a pressure plate fixedly connected to the bottom of the electric telescopic rod, located within the inner cavity of the positioning box.

[0006] Using the above scheme, the lead screw is driven by the No. 1 motor to rotate, the lead screw drives the sliding sleeve to move laterally, the sliding sleeve drives the connecting column to move laterally, and the connecting column drives the No. 1 disc and the positioning box connected to it to move laterally, thereby changing the distance between the two positioning boxes, improving the flexibility of the device, and it can be applied to optical cables of different lengths for torsion testing.

[0007] In a preferred embodiment of the optical cable torsion testing device, a power supply box is fixedly connected to the inner side of the L-shaped frame and to the bottom of the second motor, and the inner cavity of the power supply box is equipped with a storage battery.

[0008] By adopting the above solution, the electrical equipment is powered by a storage battery to maintain its normal operation.

[0009] In a preferred embodiment of the optical cable torsion testing device, a PLC controller is fixedly connected to the outside of the L-shaped frame, and the PLC controller is electrically connected to the No. 2 motor via a connecting line.

[0010] With the above solution, since the PLC controller has a torque control mode, the torque of the second motor can be controlled in real time, making it convenient for users to operate.

[0011] In a preferred embodiment of an optical cable torsion testing device, a groove is provided at the bottom of the base box, and a slider is fixedly connected to the bottom of the sliding sleeve, with the bottom of the slider slidably connected to the inner wall of the groove.

[0012] By adopting the above scheme, the slider is limited by the setting of the slide groove, which assists the slide sleeve in moving and improves the stability of the slide sleeve when moving.

[0013] In a preferred embodiment of an optical cable torsion testing device, the surface of the base box is provided with a protective shell, and the protective shell is fixedly connected to the base box by fastening bolts.

[0014] By adopting the above solution and using fastening bolts, the protective shell can be quickly disassembled and assembled on the surface of the base box, thereby enabling regular maintenance of the internal mechanisms of the base box.

[0015] In a preferred embodiment of the optical cable torsion testing device, one end of the auxiliary rotating rod is movably connected to a bearing, and one side of the bearing is fixedly connected to the inner side of the L-shaped frame.

[0016] By adopting the above solution and using bearings, one end of the auxiliary rotating rod is prevented from being suspended in the air, thus preventing vibration.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. This utility model uses a No. 1 motor to drive a lead screw to rotate, which in turn drives a sliding sleeve to move laterally. The sliding sleeve then drives a connecting column to move laterally, which in turn drives a No. 1 disc and a positioning box connected to it to move laterally. This changes the distance between the two positioning boxes, improving the flexibility of the device. It is also applicable to torsion tests on optical cables of different lengths.

[0019] 2. This utility model uses an electric telescopic rod to move the pressure plate downwards until the bottom of the pressure plate is tightly attached to the surface of the optical cable, and then the movement stops, thus pressing down and fixing the optical cable to prevent the cable from rotating during the twisting process, which would result in poor cable twisting effect.

[0025] Please see Figure 1-4 A fiber optic cable torsion testing device includes a base box 1. A No. 1 motor 2 is fixedly installed on the right side of the inner cavity of the base box 1. A lead screw 3 is fixedly connected to the output end of the No. 1 motor 2. A sliding sleeve 4 is threaded onto the surface of the lead screw 3. A connecting post 5 is fixedly connected to the top of the sliding sleeve 4. A No. 1 disc 6 is fixedly connected to the top of the connecting post 5. An L-shaped frame 10 is fixedly connected to the bottom of the right side of the base box 1. Figure 2 As shown, a PLC controller is fixedly connected to the outer side of the L-shaped frame 10, and the PLC controller is electrically connected to the second motor 11 via a connecting cable. Because the PLC controller has a torque control mode, it can control the torque of the second motor 11 in real time, facilitating user operation. The second motor 11 is fixedly installed on the inner side of the L-shaped frame 10. A main rotating rod 12 is fixedly connected to the output end of the second motor 11. A main gear 13 is fixedly connected to one end of the main rotating rod 12. A secondary gear 14 meshes with the surface of the main gear 13, and a secondary rotating rod 15 is fixedly connected to the inner wall of the secondary gear 14. Figure 1 As shown, a bearing is movably connected to one end of the auxiliary rotating rod 15, and one side of the bearing is fixedly connected to the inner side of the L-shaped frame 10. The bearing prevents one end of the auxiliary rotating rod 15 from being suspended and thus vibrating. A second disc 16 is fixedly connected to one end of the auxiliary rotating rod 15. Positioning boxes 7 are fixedly connected to one side of both the first disc 6 and the second disc 16. An electric telescopic rod 8 is fixedly connected to the top of the positioning box 7. A pressure plate 9 is fixedly connected to the bottom of the electric telescopic rod 8 and located inside the positioning box 7. The first motor 2 drives the lead screw 3 to rotate, which in turn drives the sliding sleeve 4 to move laterally. The sliding sleeve 4 then drives the connecting column 5 to move laterally, which in turn drives the first disc 6 and the positioning box 7 connected to it to move laterally. This changes the distance between the two positioning boxes 7, improving the flexibility of the device and making it suitable for torsion tests on optical cables of different lengths.

[0026] See Figure 2 As shown, a power supply box is fixedly connected to the inner side of the L-shaped frame 10 and to the bottom of the second motor 11. The power supply box contains a battery, which supplies power to the electrical equipment and maintains its normal operation. Figure 4 As shown, a sliding groove is provided at the bottom of the base box 1, and a slider is fixedly connected to the bottom of the sliding sleeve 4. The bottom of the slider is slidably connected to the inner wall of the sliding groove. The sliding groove limits the slider and assists the sliding sleeve 4 in moving, thus improving the stability of the sliding sleeve 4 during movement. Figure 1 As shown, the surface of the base box 1 is provided with a protective shell, and the protective shell is fixedly connected to the base box 1 by fastening bolts. The setting of fastening bolts makes it easy to quickly install and remove the protective shell from the surface of the base box 1, thereby enabling regular maintenance of the internal mechanism of the base box 1.

[0027] In use, firstly, the optical cable is passed through the through hole on the other side of the first disc 6 and through the inner cavity of the positioning box 7, so that the optical cable is transported to the position of the positioning box 7 located on the side of the second disc 16 until both ends of the optical cable are located in the inner cavities of the two positioning boxes 7 respectively, and then the movement stops. Next, the electric telescopic rod 8 is activated, which drives the pressure plate 9 to move downwards until the bottom of the pressure plate 9 is in close contact with the surface of the optical cable, and then the movement stops, pressing down and fixing the optical cable to prevent the cable from rotating during the twisting process. Then, the second motor 11 is activated, which drives the main rotating rod 12 to rotate, which drives the main gear 13 to rotate, which drives the secondary gear 14 to rotate, and the secondary gear 14, with the cooperation of the secondary rotating rod 15, drives the second disc 16. The first disc 6 rotates, driving the connected positioning box 7 to rotate via the second disc 16. During this process, one end of the optical cable is fixed while the other end rotates, thus achieving the purpose of the torsion test. When the optical cable to be tested is too long or too short, the first motor 2 is started, converting electrical energy into mechanical energy and driving the lead screw 3 to rotate. Since the thread on the surface of the lead screw 3 is compatible with the thread on the inner wall of the sliding sleeve 4, when the lead screw 3 is rotating, it can drive the sliding sleeve 4 to move laterally. The sliding sleeve 4 drives the connecting column 5 to move laterally, and the connecting column 5 drives the first disc 6 and the connected positioning box 7 to move laterally, thereby changing the distance between the two positioning boxes 7, improving the flexibility of the device, and making it suitable for torsion tests on optical cables of different lengths.
