Abstract
Description
Technical Field
[0001] This utility model relates to the field of wire retractor technology, specifically a portable wire retractor. Background Technology
[0002] In modern production and daily life, cable retractors, as devices for storing various types of cables, are widely used in many fields such as homes, industry, medical care, and communications. Whether it's everyday power cords and data cables, industrial cables and flexible hoses, or connecting wires in medical equipment, cable retractors are needed to achieve orderly storage and convenient access.
[0003] In existing technologies, traditional portable wire retractors are usually designed with a fixed radius roller. A single radius cannot accommodate wires of various diameters at the same time. Furthermore, once the wire is wrapped around the roller, it is not easy to separate the wire from the roller because the roller radius is fixed and the structure is closed. Tools are needed to forcibly pry or pull the wire. The insulation layer on the surface of the wire will be damaged due to friction and compression. The exposed copper core not only easily causes the risk of electric shock, but may also affect the conductivity due to oxidation and corrosion, resulting in unnecessary waste of resources.
[0004] In view of the above, this application is hereby submitted. Utility Model Content
[0005] The purpose of this invention is to provide a portable wire retractor to solve the problems mentioned in the background art.
[0006] To solve the above-mentioned technical problems, this utility model provides a portable wire retractor, including a support frame, a connecting block installed on the outer wall of the support frame, an adjustment component installed on one side of the connecting block, the adjustment component including a rotating rod rotatably connected to the connecting block, a sleeve threadedly connected to the outer wall of the rotating rod, multiple first fixing blocks and second fixing blocks respectively installed at both ends of the sleeve, a first sliding block and a second sliding block slidably connected to the top of each first fixing block and second fixing block respectively, a support plate fixedly connected to the top of the first sliding block and the second sliding block, limit rods fixedly connected to both sides of the bottom end of the support plate, a first baffle and a second baffle rotatably connected to both ends of the rotating rod respectively, multiple guide grooves are opened on the outer walls of the first baffle and the second baffle, and each support plate is slidably connected to the guide grooves opened on the outer walls of the first baffle and the second baffle respectively through two limit rods.
[0007] Furthermore, anti-slip pads are fitted on both sides of the bottom of the support frame, and the anti-slip pads are made of wear-resistant material.
[0008] Furthermore, a gripping rod is fixedly connected to one side of the outer wall of the second baffle, and the surface of the gripping rod is integrally formed with anti-slip particles.
[0009] Furthermore, the outer wall of the middle section of the rotating rod is threaded, and the inner wall of the sleeve is threaded. The sleeve is threadedly connected to the outer wall of the middle section of the rotating rod through the threaded groove.
[0010] Furthermore, a limit block is fixedly connected to one end of the rotating rod, and the rotating rod is rotatably connected to one side of the second baffle through the limit block.
[0011] Furthermore, a sliding post is installed on the side of each of the two limiting rods that are far apart, and each limiting rod is slidably connected to the inner wall of the guide groove through the sliding post.
[0012] Furthermore, there are five first fixed blocks and five second fixed blocks, and each first fixed block and each second fixed block has a first sliding block and a second sliding block slidably connected to its top, with eight first sliding blocks and eight second sliding blocks.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] 1. For wires with thinner diameters, the roller radius can be reduced by adjusting the adjustment component to decrease the number of redundant turns during winding, avoiding interlayer compression and nesting caused by multiple layers of winding. For wires with thicker diameters, simply increase the roller radius to provide sufficient space for the wire, allowing the wire to be in a naturally relaxed state during winding. This effectively prevents the insulation layer from cracking and aging due to excessive tension, as well as fatigue damage to the internal copper core caused by repeated bending, thus improving the flexibility of equipment use.
[0015] 2. When the wire becomes tangled or stuck, the radius of the roller can be adjusted by rotating it to change the gap and stress between the roller and the wire. This makes it easier to remove the wire manually or with the help of tools, eliminating the need to force it into the fixed gap and pry or pull it. This avoids friction damage to the wire insulation caused by the separation operation, and reduces the risk of electric shock and damage to conductivity caused by exposed copper core.

[0023] 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.
[0024] Please see Figures 1-6This utility model provides a technical solution: a portable wire retractor, including a support frame 1, a connecting block 2 installed on the outer wall of the support frame 1, and an adjustment component installed on one side of the connecting block 2. The adjustment component includes a rotating rod 3 rotatably connected to the connecting block 2, and a sleeve 4 threadedly connected to the outer wall of the rotating rod 3. Because the sleeve 4 is threadedly connected to the rotating rod 3, when the operator rotates the rotating rod 3, the sleeve 4 moves linearly along the axial direction of the rotating rod 3 under the drive of the rotating rod 3. When the rotating rod 3 is stopped, the sleeve 4 can stably maintain its current position and will not easily move due to external force. Multiple first fixing blocks 5 and second fixing blocks 6 are respectively installed at both ends of the sleeve 4. The top of each first fixing block 5 and second fixing block 6 is slidably connected to a first sliding block 7 and a second sliding block 8. The top of the first sliding block 7 and the second sliding block 8 is fixedly connected to a support plate 9. The first fixing blocks 5 and the second fixing blocks 6 move with the sleeve 4, and the movement of the sleeve 4 is transmitted to the first sliding blocks 7 and the second sliding blocks 8 through the first fixing blocks 5 and the second fixing blocks 6. Simultaneously distributing the force makes the motion transmission more stable. Limiting rods 10 are fixedly connected to both sides of the bottom end of the support plate 9. The two ends of the rotating rod 3 are rotatably connected to a first baffle 11 and a second baffle 12, respectively. Multiple guide grooves 13 are provided on the outer walls of both the first baffle 11 and the second baffle 12. Each support plate 9 is slidably connected to the guide grooves 13 on the outer walls of the first baffle 11 and the second baffle 12 via two limiting rods 10. During the cable winding process, the support plate 9 provides support and guidance for the wire, preventing… The wires are scattered and tangled, ensuring that they can be neatly placed on the take-up device. During wire release, the auxiliary wires are released smoothly to avoid jamming. The limit rod 10 is inserted into the guide groove 13 of the first baffle 11 and the second baffle 12, which guides and restricts the movement of the support plate 9, ensuring that the support plate 9 moves along the predetermined trajectory and preventing the support plate 9 from deviating or shaking during the movement. At the same time, the overall premise is that the operator holds one of the first baffle 11 and the second baffle 12 and rotates the rotating rod 3.
[0025] See Figure 1 , Figure 2 The support frame 1 has anti-slip pads 14 on both sides of its bottom end. The anti-slip pads 14 are made of wear-resistant material. The anti-slip pads 14 prevent the take-up reel from sliding during operation by increasing friction, which effectively improves the stability of the take-up reel and reduces the inconvenience and safety hazards caused by sliding. The anti-slip pads 14 are made of nitrile rubber.
[0026] See Figure 2 A grip rod 15 is fixedly connected to one side of the outer wall of the second baffle 12. The surface of the grip rod 15 is integrally formed with anti-slip particles. The grip rod 15 provides a convenient operating grip point for the user, and the user can rotate the component by gripping the grip rod 15.
[0027] See Figure 4 The outer wall of the middle section of the rotating rod 3 is threaded, and the inner wall of the sleeve 4 is threaded. The sleeve 4 is threadedly connected to the outer wall of the middle section of the rotating rod 3 through the threaded groove. When the rotating rod 3 stops rotating, the sleeve 4 will automatically lock in the current position due to the self-locking effect of the thread, and will not move easily due to external force, thus avoiding the wire from getting tangled due to the movement of parts during the winding and unwinding process.
[0028] Working principle: The operator holds the first baffle 11 or the second baffle 12 and then rotates the rotating rod 3. The sleeve 4 will move linearly along the axis of the rotating rod 3. When the sleeve 4 moves, the first fixed block 5 and the second fixed block 6 move accordingly and transmit the motion to the first sliding block 7 and the second sliding block 8, which in turn drives the support plate 9 to move. The limiting rods 10 on both sides of the bottom end of the support plate 9 are inserted into the guide grooves 13 opened on the outer wall of the first baffle 11 and the second baffle 12, which guide and restrict the movement of the support plate 9, ensuring that the support plate 9 moves along the predetermined trajectory and preventing deviation or shaking. This allows for adjustment of the overall size of the support plate 9, improving the flexibility of equipment use. When the rotating rod 3 is stopped, the sleeve 4 can be stably maintained in the current position due to the self-locking effect of the thread and will not move easily due to external force, thus avoiding the tangling of the wires due to the movement of parts during the winding and unwinding process.
[0029] The control method of this utility model is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art, which is common knowledge in the field. Furthermore, since this utility model is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail here.
[0030] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
