Description

Technical Field

[0001] This utility model relates to the field of wire harness pay-off frame technology, and in particular to an open wire harness pay-off frame with a winding function. Background Technology

[0002] An open-type cable harness feeder is a device specifically designed for laying and retracting cables during cable harness installation. Its structural design effectively prevents cable tangling and knotting, and it is commonly used in industrial manufacturing and construction engineering. Cables are prone to tangling and knotting due to external forces during laying and use, especially longer cable harnesses. To effectively control cable tension, prevent disorderly tangling, and ensure that the cable harness remains smooth, an open-type cable harness feeder with a retraction function is required.

[0003] Open wire harness feeders can be divided into several types, namely manual feeders, automatic feeders, and fixed feeders. These types of open wire harness feeders can effectively improve the efficiency and convenience of wire harness management according to specific work needs and usage environments. Among them, manual feeders have a simple structure and rely on manual operation for feeding and winding, making them suitable for scenarios where wire harnesses are short or not frequently used.

[0004] However, existing wire harness pay-off racks have significant shortcomings in practical applications, especially in the winding operation, which requires manual rotation of the reel. Since wire harnesses are often quite long, manual winding is time-consuming and labor-intensive, and prone to tangling or knotting due to improper operation, thus affecting the normal use of the wire harness. This reliance on manual operation is not only inefficient but also increases the operator's workload. Especially in situations involving large-scale wire harness use, there is an urgent need for an open-type wire harness pay-off rack that can automatically wind and is easy to operate to improve efficiency and convenience. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an open wire harness unwinding rack with a winding function, which aims to improve the problem that the wire harness winding device needs to manually rotate the wheel when storing the wire harness.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an open wire harness unwinding rack with a winding function, including a base, a support rod fixedly connected to the top of the base, a housing fixedly connected to the outer wall of the support rod, a winding assembly disposed inside the housing, a support frame fixedly connected to the top of the base, a limit assembly disposed inside the support frame, a fixing assembly disposed inside the support frame, and a positioning assembly disposed inside the support frame.

[0007] The winding assembly includes a rotating shaft, which is rotatably connected inside the housing. A slot is provided inside the housing. A torsion spring is fixedly connected to one end of the rotating shaft, and the other end of the torsion spring is engaged with the slot.

[0008] As a further description of the above technical solution:

[0009] The fixing component includes a clamp plate, which is slidably connected inside the support frame, and a pull rod is fixedly connected to one side of the clamp plate.

[0010] As a further description of the above technical solution:

[0011] The positioning component includes a Z-shaped plate, one end of which is fixedly connected to the outer wall of the clamping plate, and the other end of which is fixedly connected to a ball column.

[0012] As a further description of the above technical solution:

[0013] The limiting component includes a wedge-shaped locking block, one side of which is fixedly connected inside the support frame, and the wedge-shaped locking block is engaged with the ball column.

[0014] As a further description of the above technical solution:

[0015] A limiting block is fixedly connected to the top of the base, and a connecting rod is rotatably connected inside the limiting block. An anti-slip strip is fixedly connected to the outer wall of the connecting rod.

[0016] As a further description of the above technical solution:

[0017] One end of the connecting rod is rotatably connected to a second connecting block, and the inside of the limiting block is rotatably connected to a first connecting block.

[0018] As a further description of the above technical solution:

[0019] A telescopic rod is fixedly connected to one side of the connecting block 2, and the other end of the telescopic rod is fixedly connected to one side of the connecting block 1.

[0020] As a further description of the above technical solution:

[0021] A spring is fitted on the outer wall of the telescopic rod. One end of the spring is fixedly connected to one side of the connecting block two, and the other end of the spring is fixedly connected to one side of the connecting block one.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, the clamping plate is first lifted upward from the support frame by the pull rod, and the pull rod drives the clamping plate downward. The torsion spring resets and drives the wire harness to be stored through the rotating shaft, thus achieving the effect of automatic winding and fixing of the wire harness. This solves the problem that the wire harness winding device needs to manually rotate the wheel when storing the wire harness, and improves the convenience of the open wire harness unloading rack.

[0024] 2. In this utility model, one end of the connecting rod is connected to the limiting block, and the other end is connected to the limiting block through a telescopic rod. At the same time, the tension of the spring supports the connecting rod so that one end can always fit against the outer wall of the wire harness for limiting, thereby achieving the effect of limiting the wire harness. This solves the problem that the wire harness is easily misaligned and gets stuck during wire feeding, and improves the practicality of the open wire feeding rack. Attached Figure Description

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figure 1-Figure 3This utility model provides an embodiment of an open wire harness feeder with a winding function, comprising a base 1, a support rod 2 fixedly connected to the top of the base 1, a housing 3 fixedly connected to the outer wall of the support rod 2, a winding assembly inside the housing 3, which can provide support and stability when storing the wire harness, a support frame 7 fixedly connected to the top of the base 1, the support frame 7 providing a stable frame structure for placing the wire harness, a limit component inside the support frame 7 for limiting the wire harness during the feeding or winding process, ensuring that the wire harness will not be misaligned or slipped during feeding or winding, a fixing component inside the support frame 7 to provide stable support for the wire harness, and a positioning component inside the support frame 7 to ensure that the wire harness can be placed and stored in the specified position to avoid loosening or misalignment;

[0033] The winding assembly includes a rotating shaft 4, which is rotatably connected inside the housing 3, enabling smooth winding of the wire harness. A slot 5 is provided inside the housing 3 to engage with the winding assembly, making the structure more stable. A torsion spring 6 is fixedly connected to one end of the rotating shaft 4. The torsion spring 6 provides elastic force during winding, pushing the wire harness to automatically retract and wind up. The other end of the torsion spring 6 engages with the slot 5. This engagement structure ensures the stability of the rotating shaft 4 and provides continuous rebound force, guaranteeing smooth winding of the wire harness. The fixing assembly includes a clamping plate 9, which is slidably connected inside the support frame 7. It can clamp and fix the wire harness when needed, preventing movement. A pull rod 11 is fixedly connected to one side of the clamping plate 9. The pull rod 11 provides a convenient manual operation interface for the operator. It can be pulled to control the movement of the clamp 9, so as to quickly fix and loosen the wire harness. The positioning component includes a Z-shaped plate 12. One end of the Z-shaped plate 12 is fixedly connected to the outer wall of the clamp 9. The structural design increases the positioning accuracy of the clamp 9. The other end of the Z-shaped plate 12 is fixedly connected to a ball post 10. The ball post 10 can rotate flexibly and work in conjunction with the limiting component. The limiting component includes a wedge-shaped block 8. One side of the wedge-shaped block 8 is fixedly connected to the inside of the support frame 7. The wedge-shaped block 8 is engaged with the ball post 10 to realize the limiting and fixing function of the ball post 10, which further enhances the stability of the wire harness when releasing and retracting the wire harness and prevents the wire harness from loosening or slipping.

[0034] Specifically, the wire harness is stored on the rotating shaft 4. When the wire harness is needed, it is passed between the limiting block 13 and the support frame 7. During the wire harness extraction, the wire harness drives the rotating shaft 4 to rotate. One end of the rotating shaft 4 is driven by a torsion spring 6, which stores force during rotation. The other end of the torsion spring 6 is fitted into the slot 5 and fixedly connected to the housing 3, thus ensuring smooth force storage. When the wire harness needs to be fixed, the clamping plate 9 is raised from the support frame 7 by pulling the lever 11 upward. The clamping plate 9 is then connected to the ball post 10 via the Z-shaped plate 12. The ball post 10 is locked in position by fitting into the top of the wedge-shaped block 8. The movement of the ball post 10 causes the Z-shaped plate 12 to deform, thereby making the clamping plate 9 fit tightly and effectively fix the wire harness. When the wire harness is no longer in use, simply pull down the lever 11 to reset the clamp 9. As the torsion spring 6 returns to its original position, it drives the wire harness to retract via the rotating shaft 4, thus achieving automatic winding of the wire harness. This ensures that the wire harness is firmly fixed during the winding process, greatly improving the ease of use and work efficiency of the equipment.

[0035] Reference Figure 4 A limiting block 13 is fixedly connected to the top of the base 1. The limiting block 13 serves to limit the wire harness, ensuring that the wire harness will not slip out of the designated area during use. A connecting rod 14 is rotatably connected inside the limiting block 13. The rotatable connection of the connecting rod 14 ensures that the fixed position of the wire harness can be flexibly adjusted during the limiting process. An anti-slip strip 19 is fixedly connected to the outer wall of the connecting rod 14. The anti-slip strip 19 provides additional friction for the wire harness, preventing the wire harness from sliding inside the limiting block 13, thus improving the limiting effect and stability. A connecting block 2 16 is rotatably connected to one end of the connecting rod 14. The connecting block 2 16 is responsible for connecting the connecting rod 14 to other structures, ensuring the linkage of the entire limiting mechanism. A connecting block 15 is also rotatably connected inside the limiting block 13. The cooperation between the connecting block 15 and the limiting block 13 ensures the stable operation of the entire limiting device. A telescopic rod 1 is fixedly connected to one side of the connecting block 2 16. 7. The telescopic rod 17 provides the necessary elastic telescopic function to ensure that it can be adaptively adjusted according to the different diameters of the wire harness during the limiting process, thus ensuring the effectiveness of the limiting. The other end of the telescopic rod 17 is fixedly connected to one side of the connecting block 15. Through the connection with the connecting block 15, the telescopic movement of the telescopic rod 17 can be transmitted to the entire limiting system more stably and effectively. A spring 18 is sleeved on the outer wall of the telescopic rod 17. The spring 18 plays the role of rebound reset in the limiting device, ensuring that the limiting device can automatically return to its original state after use, thus improving the convenience of the device and the smoothness of operation. One end of the spring 18 is fixedly connected to one side of the connecting block 2 16, while the other end of the spring 18 is fixedly connected to one side of the connecting block 15. This design can ensure that the spring 18 is evenly stressed, making the limiting device more stable during the rebound process and effectively enhancing the reliability of the limiting device.

[0036] Specifically, when the wire harness is limited within the limiting block 13, it is effectively limited and controlled by a connecting rod 14 installed inside the limiting block 13. One end of the connecting rod 14 is tightly connected to the limiting block 13, while the other end is connected to the limiting block 13 via a telescopic rod 17, allowing the connecting rod 14 to extend and retract freely, thus flexibly adapting to different diameter changes in the wire harness. Simultaneously, the other end of the connecting rod 14 is continuously supported by the tension of the spring 18, ensuring it remains in contact with the outer wall of the wire harness and maintains a stable limiting effect. The tension of the spring 18 provides continuous support for the entire system, preventing the wire harness from shifting or loosening due to shaking or external tension, further enhancing the accuracy and reliability of the limiting. This design, through a reasonable mechanical structure, ensures the wire harness remains stable during use, avoiding the loosening or instability of traditional limiting methods, effectively improving the safety and service life of the wire harness. It also facilitates quick adjustment and fixation by operators during use and maintenance, achieving precise limiting of the wire harness.

[0037] Working principle: When using this open-type wire harness unwinding rack with winding function, the wire harness is first stored on the rotating shaft 4. When the wire harness is needed, it passes between the limiting block 13 and the support frame 7. As the wire harness is pulled out, it drives the rotating shaft 4 to rotate. One end of the rotating shaft 4 drives the torsion spring 6 to rotate and store force. The other end of the torsion spring 6 is fitted into the slot 5 and connected to the housing 3. When the wire harness needs to be fixed, the clamping plate 9 is lifted upwards from the support frame 7 by the pull rod 11. The clamping plate 9 is then connected to the ball post 10 via the Z-shaped plate 12. The ball post 10 is engaged with the top of the wedge-shaped locking block 8. The ball post 10 can... The Z-shaped plate 12 deforms, which in turn fixes the wire harness through the clamping plate 9. When storing, the pull rod 11 pulls the clamping plate 9 downward, and then the torsion spring 6 resets and drives the wire harness to be stored through the rotating shaft 4, achieving the effect of automatic winding and fixing of the wire harness. When the wire harness is limited within the limiting block 13, the wire harness is limited by the internal connecting rod 14. One end of the connecting rod 14 is connected to the limiting block 13, and the other end is connected to the limiting block 13 through the telescopic rod 17. At the same time, the tension of the spring 18 supports the connecting rod 14 so that one end can always be in contact with the outer wall of the wire harness for limitation, thus achieving the effect of limiting the wire harness.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
