Description

Technical Field

[0001] This utility model relates to the field of optical cable equipment technology, and in particular to a tensile-resistant optical cable constant tension adjustment device. Background Technology

[0002] With the rapid development of the communications industry, optical cables, as an important carrier of information transmission, are widely used in long-distance communications, local area networks and other fields. During the laying, operation and maintenance of optical cables, their tension state directly affects transmission performance and service life.

[0003] Existing tensile-resistant optical cable constant tension adjustment devices are mostly unable to flexibly adjust to optical cables of different diameters and materials. As a result, a single device can often only be adapted to optical cables of a specific specification. When multiple specifications of optical cables need to be processed, different devices must be replaced, which not only increases equipment procurement costs but also reduces work efficiency and extends the construction cycle. Therefore, we propose a tensile-resistant optical cable constant tension adjustment device to solve this problem. Utility Model Content

[0004] The purpose of this invention is to provide a tensile-resistant optical cable constant tension adjustment device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A constant tension adjustment device for a tensile-resistant optical cable includes: a tensile-resistant optical cable body and a worktable. The top of the worktable has two sets of frames (frame 1 and frame 2). Drive shafts are rotatably mounted on the inner walls of both sides of each set of frames 1. A turntable is fixedly mounted at one end of each of the four drive shafts. Synchronous pulleys are fixedly mounted at the other ends of the two sets of drive shafts located at the rear. Synchronous belts are driven onto the outer sides of the two sets of synchronous pulleys. Four sets of guide rods are fixedly mounted inside each of the two sets of frames 1, located on the same side. Two sets of wheel seats are slidably installed on the outer side of each of the four sets of guide rods. Guide rollers are hinged inside each of the four sets of wheel seats. Connecting rods are hinged between the two sides of each of the four sets of wheel seats and the corresponding turntables. A screw is rotatably installed on the top of the frame body. A threaded sleeve is threadedly connected to the outer side of the screw. Wheel seat two is fixedly installed at the bottom of the threaded sleeve. A tension wheel is hinged inside the wheel seat two. The outer side of the tensile-resistant optical cable body abuts between two adjacent sets of guide rollers and is wound around the outer side of the tension wheel.

[0007] Preferably, a support plate is fixedly installed on one side of one set of the frame body, and a drive motor is fixedly installed on the top of the support plate. One side of one set of the synchronous pulleys is fixedly installed on the output end of the drive motor. Two sets of lifting rods are fixedly installed between the wheel seat and the top inner wall of the frame body.

[0008] Preferably, four sets of support legs are fixedly installed at the bottom of the workbench, and anti-slip pads are fixedly installed at the bottom of each of the four sets of support legs.

[0009] Preferably, the outer surface of the tension wheel is made of rubber and has anti-slip texture.

[0010] Preferably, an adjusting motor is fixedly installed on the top of the second frame, and one end of the screw is fixedly installed on the output end of the adjusting motor.

[0011] Preferably, each of the four sets of wheel seats has four sets of sliding holes inside, and the sliding holes are adapted to the corresponding guide rods.

[0012] In this utility model, the tensile-resistant optical cable constant tension adjustment device increases the friction between the tension wheel and the optical cable by using rubber material and anti-slip texture on the surface, thus preventing slippage and ensuring the accuracy of tension adjustment; the anti-slip pads on the support legs at the bottom of the workbench enhance the overall stability of the device, ensuring that the adjustment effect is not affected by vibration or other factors during operation.

[0013] In this utility model, a tensile-resistant optical cable constant tension adjustment device is provided. An adjustment motor drives the screw to rotate. Since the screw is threadedly connected to the threaded sleeve, and the lifting rod between the wheel seat two and the inner top wall of the frame two plays a limiting and guiding role for the wheel seat two, when the screw rotates, the threaded sleeve will drive the wheel seat two and the tension wheel inside the wheel seat two to move up and down. The up and down movement of the tension wheel changes the pressure applied to the optical cable. The precise rotation of the screw can be converted into the precise lifting and lowering of the wheel seat two and the tension wheel driven by the threaded sleeve, so that the pressure applied by the tension wheel to the optical cable can be precisely controlled, thereby realizing the fine adjustment of the optical cable tension and meeting the precise requirements of optical cable tension in different scenarios.

[0014] This utility model features a reasonable structural design. By coordinating the drive motor, synchronous pulleys, and synchronous belt, two sets of synchronous pulleys rotate synchronously, thereby driving the transmission shaft connected to the two sets of synchronous pulleys and the turntable at one end of the transmission shaft to rotate. When the turntable rotates, it pushes the wheel seat to slide outside the guide rod through the connecting rod hinged between the turntable and the wheel seat. The sliding of the wheel seat changes the position of the guide roller, thereby adjusting the guiding angle and tension of the optical cable within the frame, ensuring the stability of the optical cable transmission direction, and greatly improving its versatility to adapt to tensile optical cables of different sizes and diameters. This adjustability greatly enhances the versatility of the device, making it no longer limited to optical cables of specific sizes, but adaptable to tensile optical cables of various specifications. Thus, it can play a stable role in different optical cable laying and usage scenarios, reducing the cost and trouble of replacing equipment due to changes in optical cable size, and enhancing the practical value of the device.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figure 1-4 A constant tension adjustment device for a tensile optical cable includes: a tensile optical cable body 1 and a workbench 2. Two sets of frames 1-4 and 2-12 are arranged on the top of the workbench 2. Drive shafts 19 are rotatably mounted on the inner walls of both sides of the two sets of frames 1-4. A turntable 20 is fixedly mounted on one end of each of the four sets of drive shafts 19. Synchronous pulleys 7 are fixedly mounted on the other ends of the two sets of drive shafts 19 located on the rear side. Synchronous belts 8 are driven onto the outer sides of the two sets of synchronous pulleys 7. Four sets of guide rods 9 are fixedly mounted inside the two sets of frames 1-4. The four sets of guide rods 9 located on the same side... Two sets of wheel seats 10 are slidably installed on the outer side of each of the four sets of wheel seats 10. Guide rollers 11 are hinged inside each of the four sets of wheel seats 10. Connecting rods 21 are hinged between the two sides of the four sets of wheel seats 10 and the corresponding turntables 20. A screw 15 is rotatably installed on the top of the frame 2 12. A threaded sleeve 16 is threadedly connected to the outer side of the screw 15. Wheel seat 2 14 is fixedly installed at the bottom of the threaded sleeve 16. A tension wheel 18 is hinged inside the wheel seat 2 14. The outer side of the tensile-resistant optical cable body 1 abuts between two adjacent sets of guide rollers 11 and is wound around the outer side of the tension wheel 18.

[0022] In this embodiment, a support plate 5 is fixedly installed on one side of one set of frame 4, and a drive motor 6 is fixedly installed on the top of the support plate 5. One side of one set of synchronous wheels 7 is fixedly installed on the output end of the drive motor 6. Two sets of lifting rods 17 are fixedly installed between the wheel seat 14 and the top inner wall of the frame 12 to prevent the wheel seat 14 from shifting with the screw 15, ensuring the tension wheel 18 rises and falls stably and guaranteeing the stability of tension adjustment.

[0023] In this embodiment, four sets of support legs 3 are fixedly installed at the bottom of the workbench 2. Anti-slip pads are fixedly installed at the bottom of each of the four sets of support legs 3 to ensure the overall stability of the device and to ensure the smooth operation of the optical cable tension adjustment.

[0024] In this embodiment, the outer surface of the tension wheel 18 is made of rubber and has anti-slip texture to ensure the effectiveness and accuracy of tension adjustment and avoid tension loss of control due to slippage.

[0025] In this embodiment, an adjustment motor 13 is fixedly installed on the top of the frame 2 12, and one end of the screw 15 is fixedly installed on the output end of the adjustment motor 13 to ensure that the optical cable is always in a suitable tension state.

[0026] In this embodiment, each of the four sets of wheel seats 10 has four sets of sliding holes inside. The multiple sets of sliding holes are adapted to the corresponding guide rods 9, which reduces the impact of the wheel seat 10 shaking on the tension of the optical cable and improves the reliability of the device operation.

[0027] In this embodiment, during use, when the device is working, the tensile optical cable body 1 passes sequentially between two adjacent sets of guide rollers 11 in the two sets of frame one 4, and wraps around the outside of the tension wheel 18 in the frame two 12 to form a stable transmission path.

[0028] By starting the drive motor 6, the synchronous pulley 7 connected to it is driven to rotate. Since the two sets of synchronous pulleys 7 are connected by the synchronous belt 8, the other set of synchronous pulleys 7 will rotate synchronously, thereby driving the drive shaft 19 connected to the two sets of synchronous pulleys 7 and the turntable 20 at one end of the drive shaft 19 to rotate. When the turntable 20 rotates, it pushes the wheel seat 10 to slide outside the guide rod 9 through the connecting rod 21 hinged between it and the wheel seat 10. The sliding of the wheel seat 10 will change the position of the guide roller 11, thereby adjusting the guide angle and tension of the optical cable in the frame 4, ensuring the stability of the optical cable transmission direction, greatly improving versatility, and adapting to tensile optical cables of different sizes and diameters.

[0029] When it is necessary to change the tension of the optical cable, the screw 15 is rotated by starting the adjusting motor 13. Since the screw 15 is threadedly connected to the threaded sleeve 16, and the lifting rod 17 between the wheel seat 14 and the inner wall of the top of the frame 12 plays a limiting and guiding role on the wheel seat 14, when the screw 15 rotates, the threaded sleeve 16 will drive the wheel seat 14 and the tension wheel 18 inside the wheel seat 14 to move up and down. The up and down movement of the tension wheel 18 changes the pressure applied to the optical cable, thereby realizing the adjustment of the tension of the optical cable.

[0030] The rubber material and anti-slip texture of the tension wheel 18 increase the friction between it and the optical cable, preventing slippage and ensuring the accuracy of tension adjustment. The anti-slip pads on the support legs 3 at the bottom of the worktable 2 enhance the overall stability of the device, ensuring that the adjustment effect is not affected by vibration or other factors during operation.

[0031] The foregoing has provided a detailed description of the tensile-resistant optical cable constant tension adjustment device of this utility model. Specific embodiments have been used to illustrate the principle and implementation of this utility model. The descriptions of these embodiments are only intended to aid in understanding the method and core concept of this utility model. It should be noted that those skilled in the art can make various improvements and modifications to this utility model without departing from its principles, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
