Description

Technical Field

[0001] This utility model relates to the field of copper wire reel technology, and in particular to a reel for clamping bare copper wire. Background Technology

[0002] Bare copper wire is a type of metal wire with good electrical and thermal conductivity. It is mostly used to produce conductors and requires the use of a spool during winding.

[0003] Traditional wire reels often struggle to effectively wind long bare copper wires due to the limited inner length of the inner cylinder, necessitating the use of larger reels for secondary operations. This process is not only time-consuming and labor-intensive but can also exacerbate wire loss and operational risks. Furthermore, traditional clamps require inserting clamping rods into clamping holes, a time-consuming and slippery process. Additionally, the small fixing area of ​​traditional clamps makes them prone to loosening or falling off, reducing work efficiency and increasing safety hazards. Therefore, this paper proposes a wire reel for clamping bare copper wires to address these issues. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a wire spool for clamping bare copper wire, aiming to improve the problem in the prior art where the wire spool is prone to secondary operation and wire loosening during winding due to the limited inner cylinder length and clamp design issues when dealing with longer bare copper wires.

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

[0006] A wire spool for clamping bare copper wire includes a first baffle plate. An inner cylinder is fixedly connected to the top of the first baffle plate. A limiting groove is formed at the top of the inner cylinder. Two support rollers are fixedly connected to the top of each limiting groove. A sliding member is fixedly connected to the adjacent side of each of the two support rollers. An outer cylinder is slidably connected to the outside of the inner cylinder. A rotating shaft is rotatably connected to the middle of the outer cylinder. A circulating cross-threaded groove is formed on the outside of the rotating shaft. A driven gear is fixedly connected to the top of the rotating shaft. A second baffle plate is fixedly connected to the top of the outer cylinder. A groove is formed in the middle of the second baffle plate. A rotating member is rotatably connected to the top of the second baffle plate. A driving gear is fixedly connected to the bottom end of the rotating member. A clearance groove is formed on the left side of the top of the first baffle plate. A guide rod is fixedly connected inside the clearance groove. A fixing component for fixing one end of the bare copper wire is provided inside the clearance groove.

[0007] As a further description of the above technical solution:

[0008] The fixing component includes a ring block, which is fixedly connected to the top left side of the baffle plate. An adjusting gear is rotatably connected to the middle of the top of the ring block. A rack column is slidably connected to the middle of the ring block. A positioning roller is fixedly connected to the front end of the rack column. Two clamps are fixedly connected to the rear side of the top of the clearance groove. A pull rod is rotatably connected to the outside of the clamps. A through groove is opened in the middle of the pull rod.

[0009] As a further description of the above technical solution:

[0010] The external part of the rotating shaft is slidably connected to the inner wall of the limiting groove, and the external part of the sliding member is slidably connected to the inner wall of the circulating cross thread groove.

[0011] As a further description of the above technical solution:

[0012] The outer top end of the rotating shaft is rotatably connected to the middle part of the second baffle, and the outer side of the driven gear is rotatably connected to the inner wall of the groove;

[0013] As a further description of the above technical solution:

[0014] The external part of the driving gear is slidably connected to the inner wall of the groove, and the external teeth of the driving gear mesh with the external teeth of the driven gear.

[0020] The left and right ends of the positioning roller are slidably connected to the inner wall of the through groove, and the rear sides of the two pull rods are rotatably connected to the left and right sides of the outer side of the ring block.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, the drive gear meshes with the driven gear and rotates by the hand-tightening screw, so that the shaft fixed by the driven gear passes through the circulating cross thread groove, and drives the sliding part limited at the bottom of the inner cylinder to slide in the circulating cross thread groove. This allows the wire reel to adjust the middle length according to the actual needs of the bare copper wire length, avoiding the problems of knotting or wire damage caused by excessively thick wire winding.

[0023] 2. In this utility model, by passing one end of the bare copper wire through the guide rod and then cooperating with the adjustment gear, the adjustment gear meshes with the rack column to drive the positioning roller to retract into the ring block. This allows the positioning roller to pull the pull rod to quickly clamp and fix the copper wire at the opening of the clearance groove with the ring block as the center. This simple operation can quickly wind and fix one end of the copper wire, ensuring that the copper wire remains stable during the winding process and is not easy to loosen or fall off.

[0030] 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.

[0031] Reference Figures 1 to 3This utility model provides an embodiment of a wire spool for clamping bare copper wire, comprising a baffle plate 1, with an inner cylinder 2 fixedly connected to the top of the baffle plate 1. As one of the basic structures of the wire spool, the baffle plate 1 not only provides a stable support platform, but also ensures the structural stability of the entire wire spool through its fixed connection with the inner cylinder 2. A limiting groove 3 is formed at the top of the inner cylinder 2, and two support rollers 4 are fixedly connected to the top of each limiting groove 3. A sliding member 5 is fixedly connected to the adjacent side of the two support rollers 4. The inner cylinder 2 is the core component of the wire spool, used for winding and protecting the bare copper wire. The limiting groove 3 at its top provides a precise installation position for the support rollers 4 and the sliding member 5. An outer cylinder 6 is slidably connected to the outside of the inner cylinder 2, and a rotating shaft 7 is rotatably connected to the middle of the outer cylinder 6. The rotating shaft 7 is slidably connected to the inner wall of the limiting groove 3. The outer cylinder 6, as the outer protective shell of the wire spool, not only enhances the overall strength of the wire spool, but also realizes the rotation function of the wire spool through the rotating shaft 7 rotatably connected in the middle.

[0032] refer to Figure 2 , Figure 3 The rotating shaft 7 has a circular cross-threaded groove 8 on its outer side. The sliding member 5 is slidably connected to the inner wall of the circular cross-threaded groove 8. The circular cross-threaded groove 8 on the rotating shaft 7 cooperates with the sliding member 5 to achieve precise adjustment of the length of the inner cylinder 2. A driven gear 9 is fixedly connected to the top of the outer side of the rotating shaft 7. A second baffle 10 is fixedly connected to the top of the outer cylinder 6. The top of the outer side of the rotating shaft 7 is rotatably connected to the middle of the second baffle 10. A groove 11 is provided in the middle of the second baffle 10. A rotating member 12 is rotatably connected to the top of the second baffle 10. A driving gear 13 is fixedly connected to the bottom of the rotating member 12. The outer teeth of the driving gear 13 mesh with the outer teeth of the driven gear 9. The driven gear 9 is fixed on the rotating shaft 7 and meshes with the driving gear 13. The rotation of the rotating member 12 drives the driven gear 9 to rotate, thereby realizing the relative movement between the rotating shaft 7 and the outer cylinder 6.

[0033] The driven gear 9 is externally rotatably connected to the inner wall of the groove 11, and the driving gear 13 is externally slidably connected to the inner wall of the groove 11, ensuring that the driving gear 13 and the driven gear 9 can mesh stably for transmission. A clearance groove 14 is provided on the top left side of the baffle 1, and a guide rod 15 is fixedly connected inside the clearance groove 14. The guide rod 15 is designed to facilitate better fixation of the bare copper wire in the clearance groove 14.

[0034] refer to Figure 4The recessed groove 14 is internally equipped with a fixing component for securing one end of the bare copper wire. The recessed groove 14 is formed on the baffle plate 1 to accommodate the end of the bare copper wire and achieves quick clamping and fixing through its internal fixing component. The fixing component includes a ring block 16, which is externally fixedly connected to the top left side of the baffle plate 1. An adjusting gear 17 is rotatably connected to the middle of the top of the ring block 16, and a rack column 18 is slidably connected to the middle of the ring block 16. The external teeth of the adjusting gear 17 mesh with the external teeth of the rack column 18. A positioning roller 19 is fixedly connected to the front end of the rack column 18. The meshing of the adjusting gear 17 and the rack column 18 drives the positioning roller 19 to retract or extend, thereby achieving quick clamping of the end of the copper wire. Two clamps 20 are fixedly connected to the rear side of the top of the clearance groove 14. A pull rod 21 is rotatably connected to the outside of the clamps 20. The clamps 20 are fixed to the rear side of the clearance groove 14, serving as support points for the pull rod 21 and assisting the positioning roller 19 in clamping the copper wire. The top of the pull rod 21 is slidably connected to the top of the inner wall of the clearance groove 14. A through groove 22 is opened in the middle of the pull rod 21. The left and right ends of the positioning roller 19 are slidably connected to the inner wall of the through groove 22. The rear sides of the two pull rods 21 are rotatably connected to the left and right sides of the outer side of the ring block 16. The pull rods 21 are connected to the positioning roller 19 through the through groove 22. When the positioning roller 19 moves, the pull rods 21 slide accordingly, ensuring a uniform distribution of clamping force.

[0035] Working principle: When in use, the wire spool is first fixed to the rotating shaft 7. Then, one end of the bare copper wire is passed through the guide rod 15 in the clearance groove 14. Then, the adjusting gear 17 is turned to make the adjusting gear 17 mesh with the rack column 18 to drive the positioning roller 19 to retract and slide in the ring block 16. The positioning roller 19 slides in the through groove 22 and pulls the pull rod 21 to quickly clamp and fix the copper wire at the opening of the clearance groove 14 with the clamps 20 on both sides of the ring block 16 as the center. This ensures that the copper wire remains stable during the winding process and is not easy to loosen or fall off.

[0036] Then, adjust the lengths of the inner cylinder 2 and the outer cylinder 6 according to the length of the bare copper wire. By turning the screw 12 by hand, the driving gear 13 is driven to mesh with the driven gear 9 and rotate. This allows the rotating shaft 7 fixed by the driven gear 9 to pass through the external circulating cross thread groove 8, causing the sliding piece 5 to slide in the circulating cross thread groove 8. Since the sliding piece 5 is fixed at the top of the limiting groove 3 inside the inner cylinder 2 by the support roller 4, when the sliding piece 5 rotates along the circulating cross thread groove 8, the sliding piece 5 will drive the inner cylinder 2 to rotate and extend out of the outer cylinder 6 through the support roller 4. This allows the wire reel to adjust the middle length according to the actual needs of the bare copper wire length, avoiding the problem of knotting or wire damage caused by excessively thick wire winding.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
