Description

Technical Field

[0001] This utility model specifically relates to a cable tie traction guide structure and a cable release device using the same. Background Technology

[0002] In the production, storage, and transportation of electrical wires, packaging is a crucial process to ensure neat storage and prevent damage during transport. This process involves using cable ties to secure coils or bundles of wires, and the efficiency and stability of the cable ties directly affect the quality and efficiency of the packaging. Currently, the guide components of existing guide structures are mostly designed with fixed lengths, unable to be flexibly adjusted according to actual needs. When the guide length is insufficient, the cable ties are prone to detaching from the preset path during traction, causing friction and collision with the wires or equipment, leading to wear or even breakage of the cable ties. Utility Model Content

[0003] In view of the defects of the prior art, the technical problem to be solved by this utility model is to provide a cable tie traction guide structure and a cable release device using the same.

Attached Figure Description

[0014] Figure 1 This is a perspective view of a cable tie traction guide structure and a cable feeding device using the same, according to one embodiment of the present invention.

[0015] Figure 2 This is a front view of a cable tie traction guide structure in one embodiment of the present invention. Detailed Implementation

[0016] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0017] like Figures 1 to 2 The present invention preferably provides a cable tie traction guide structure, including a mounting base 1, a connecting shaft 2 on the mounting base 1, a guide wheel 3 and a guide rod 4 arranged sequentially along the axial direction of the connecting shaft 2, the guide wheel 3 being rotatably mounted on the connecting shaft 2, the guide rod 4 including a connecting tube 5 capable of relative telescopic displacement and a movable shaft 6, the movable shaft 6 being movably mounted in the inner cavity of the connecting tube 5, and a first guide hole 7 being provided through one end of the movable shaft 6, a tightening screw 8 being threadedly inserted into one side of the connecting tube 5 to tightly abut against the movable shaft 6, and snap-fit ​​members 9 being symmetrically arranged on both sides of the connecting shaft 2 for installation and fixation.

[0018] Specifically, the mounting base is made of metal or high-strength engineering plastic, and has a plate-like or block-like structure, serving as the mounting foundation for the overall structure. A connecting shaft is fixed to the mounting base via welding, threaded connection, or integral molding. The connecting shaft is a cylindrical rod, with guide rods and guide wheels sequentially arranged along its axial direction from one end closest to the mounting base to the other. The guide wheels are rotatably mounted on one side of the connecting shaft via a rotating shaft to guide the cable ties, reducing frictional resistance during cable traction. The guide rod includes a connecting tube capable of relative telescopic displacement and a movable shaft. The connecting tube is a tubular structure closed at one end and open at the other, with its closed end fixedly connected to the end of the connecting shaft furthest from the mounting base. The movable shaft is a rod adapted to the inner cavity of the connecting tube, movably inserted into the inner cavity of the connecting tube, and can slide and extend along the axial direction of the connecting tube. A first guide hole is provided at the end of the movable shaft away from the connecting tube, through which the cable tie can pass for guiding and constraint. A threaded hole is provided radially through one side of the connecting tube, and a tightening screw is inserted into this threaded hole through a threaded engagement. When the tightening screw is tightened, its end can press tightly against the outer wall of the movable shaft, achieving relative fixation between the movable shaft and the connecting tube. Loosening or loosening the tightening screw can adjust the extension and retraction length of the movable shaft. Furthermore, one end of the cable tie can pass through the first guide hole sequentially from the wire frame and wrap around the guide wheel to achieve guiding and traction of the cable tie.

[0019] Furthermore, the snap-fit ​​component 9 is rotatably mounted on the connecting shaft 2, and a torsion spring is provided at the rotatable connection between the snap-fit ​​component 9 and the connecting shaft 2. The torsion spring keeps the lower ends of the two snap-fit ​​components 9 moving closer together. Specifically, the elastic force of the torsion spring keeps the lower ends of the two snap-fit ​​components moving closer together, ensuring that the snap-fit ​​components have an initial snap-fit ​​preload when not subjected to external force.

[0020] Furthermore, the connecting shaft 2 is provided with a limiting sleeve 10 that can move along its axial direction. The limiting sleeve 10 can move and abut against the opposite inner sides of the upper ends of the two snap-fit ​​parts 9. Specifically, when the lower ends of the two snap-fit ​​parts are snapped into the external device, the limiting sleeve moves along the connecting shaft axial direction. The limiting sleeve can move and abut against the opposite inner sides of the upper ends of the two snap-fit ​​parts. The abutting action of the limiting sleeve restricts the opening range of the upper ends of the snap-fit ​​parts, thereby preventing the lower ends of the snap-fit ​​parts from leaving the snap-fit ​​position and enhancing the snap-fit ​​stability.

[0021] Furthermore, the limiting sleeve 10 is threaded onto the connecting shaft 2. Specifically, the threaded drive achieves self-locking of the relative position between the limiting sleeve and the connecting shaft.

[0022] Furthermore, the upper end of the connecting shaft 2 is provided with a connecting piece 11, and a second guide hole 12 is provided through the connecting piece 11. Specifically, the second guide hole is provided through the connecting piece along the traction direction of the cable tie, and the cable tie around the guide wheel passes through the second guide hole. The second guide hole and the first guide hole cooperate to form a multi-stage guide, which further improves the accuracy of the cable tie traction and avoids the cable tie from deviating during the conveying process.

[0023] Furthermore, the guide wheel 3 has a guide groove 13 recessed along its edge contour. Specifically, the cross-section of the guide groove is arc-shaped or V-shaped, adapted to the shape of the cable tie. During traction, the cable tie is embedded in the guide groove, and the two side walls of the guide groove laterally limit the cable tie, preventing it from detaching from the guide wheel and enhancing guiding stability.

[0024] A wire feeding device includes a wire feeding frame 14 and the aforementioned cable tie traction guide structure. The wire feeding frame 14 has symmetrically arranged slots 15 on both sides of its end. The lower ends of two locking members 9 can be rotatably engaged in the slots 15, and when the locking members 9 are engaged in the slots 15, the mounting base 1 is in close contact with the end of the wire feeding frame 14. Specifically, the slots are groove structures adapted to the lower ends of the locking members. During installation, the upper ends of the two locking members are pulled outwards to open the lower ends, aligning the lower ends of the two locking members with the corresponding slots. After releasing the locking members, under the action of a torsion spring, the lower ends of the locking members rotate and engage in the slots. At this time, the end face of the mounting base is in close contact with the end of the wire feeding frame, forming an axial limit, ensuring that the relative position of the guide structure and the wire feeding frame is fixed.

[0025] Furthermore, the end of the guide rod 4 can extend to the outside of the wire feeding frame 14. Specifically, the wire feeding frame has a placement rod rotatably connected by a bearing. The cable tie coil is placed on the placement rod. By adjusting the extension and retraction length of the movable shaft, one end of the guide rod can extend to the outside of the wire feeding frame. This ensures that after the cable tie is output from the wire feeding frame, it passes through the first guide hole, the guide wheel, and the second guide hole in sequence, and then accurately extends to the external binding operation area, optimizing the traction path.
