Description

Technical Field

[0001] This utility model relates to the field of cable technology, specifically a cable with a self-straightening function. Background Technology

[0002] A cable is a conductor made of one or more mutually insulated conductors and an outer insulating protective layer. It is used to transmit electrical energy or signals. It usually consists of three parts: conductor, insulation layer, and protective sheath. It is widely used in power transmission, communication, construction and other fields. According to its use, it can be divided into power cables, communication cables, control cables and other types. It has the characteristics of stable transmission and strong anti-interference ability.

[0003] To address the problem of cable internal structure damage and reduced lifespan caused by prolonged slack, a cable reel designed to maintain tautness has been developed (see patent number: 202420456430.3). This reel includes a base and a reel drum. Support rods on both sides of the base are movably connected to the reel drum via bearings, and a crank is fixed to one side of the reel drum. A first groove is provided on the upper side of the base. This cable reel, by rotating a limiting bolt, restricts the guide wheel's rapid rotation due to the connecting pad, keeping the cable taut and allowing for easy adjustment of tension. This ensures the cable remains neat and compact during winding, preventing crossing, tangling, and knotting. Rotating a knob causes two second sliders to move the guide wheels closer or further apart, adjusting the distance between them. This allows the cable reel to easily wind cables of different thicknesses.

[0004] Traditional cable straightening equipment has a relatively simple structure and lacks flexibility when dealing with cables of different specifications and materials. For example, the traction components of some equipment cannot automatically adjust the clamping force according to the thickness of the cable. If it is too tight, it can easily damage the cable sheath; if it is too loose, it cannot be straightened effectively. Disorganized cables will cause trouble for wiring construction and make it difficult to locate the problem during subsequent maintenance, increasing project costs and time costs. The accumulation of wind and rainwater can cause the cable to sway, reducing the sensitivity of the cable and the connection end, resulting in signal distortion, affecting communication quality and the accuracy of data transmission, and making it difficult to meet diverse industrial needs.

[0005] Therefore, we propose a cable with a self-straightening function to solve the problems mentioned above. Utility Model Content

[0006] The purpose of this utility model is to provide a cable with a self-straightening function in order to solve the problems of messy cables, difficulty in locating them during subsequent maintenance, increased engineering and time costs, and cable swaying caused by wind and rain, which reduces the sensitivity of the cable and connection end and affects the service life.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a cable with a self-straightening function, comprising a protective component, wherein a rotating anti-return component is provided at the top inside the protective component, a rotating straightening component is provided at the middle position inside the protective component, and a cable is wound around the outside of the rotating straightening component;

[0008] The rotating straightening assembly includes a ratchet, one end of which is fixedly provided with a cable reel, and the end of the ratchet away from the cable reel is provided with a rocker arm. The bottom of the cable reel is provided with a cylinder fixed to the ratchet.

[0009] The rotary anti-return assembly includes a pull handle, a pull rod at the bottom of the pull handle, a spring sleeved on the outside of the pull rod, and the bottom of the pull rod is rotatably connected to the pressing rod through a first bearing. The bottom of the pressing rod is provided with locking teeth.

[0010] As a further embodiment of this utility model: the protective component includes a protective cover, the top of the protective cover is provided with a mounting groove, and the middle position of the protective cover is provided with a cable channel.

[0011] As a further embodiment of this utility model: the end of the cable reel away from the ratchet is rotatably connected to the fixing rod via a second bearing, and the other end of the fixing rod is fixedly connected to the protective cover.

[0012] As a further improvement of this utility model, the locking teeth engage and rotate with the ratchet teeth around the ratchet.

[0013] As a further improvement of this utility model: the top of the inside of the protective cover is provided with a threaded groove, which is matched and threadedly connected to the thread on the top of the pull rod.

[0014] As a further improvement of this utility model, a handle is provided on the side of the rocker arm away from the cable reel.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. With the set rotation straightening component and rotation anti-return component, the cable is wound on the cable drum. Turning the handle clockwise will make the cable drum rotate clockwise, straightening the cable. When the ratchet rotates counterclockwise, the locking teeth will lock the ratchet teeth to prevent the ratchet from rotating counterclockwise, ensuring that the cable can maintain a stable straight state in various complex environments.

[0017] 2. By using the rotating anti-return assembly, pulling the handle causes the locking teeth to move upward and engage with the ratchet teeth, causing the cable reel to rotate counterclockwise. This loosens the cable to the desired position. The spring then returns to its original position, and the locking teeth and ratchet teeth lock in place, preventing further counterclockwise rotation until the cable becomes too loose. This facilitates positioning during subsequent maintenance, reduces engineering and time costs, enhances cable flexibility, makes adjustment easier, and extends service life.

[0022] 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.

[0023] Please see Figures 1-3 In this embodiment of the present invention, a cable with a self-straightening function includes a protective component 1, a rotation anti-return component 2 is provided at the top inside the protective component 1, a rotation straightening component 3 is provided at the middle position inside the protective component 1, and a cable 4 is wound around the outside of the rotation straightening component 3.

[0024] The rotating straightening assembly 3 includes a ratchet 301, a cable reel 302 fixedly mounted on one end of the ratchet 301, a rocker arm 305 mounted on the end of the ratchet 301 away from the cable reel 302, and a cylinder 104 fixed to the ratchet 301 mounted on the bottom of the cable reel 302.

[0025] The rotary check assembly 2 includes a pull handle 201, a pull rod 202 at the bottom of the pull handle 201, a spring 203 sleeved on the outside of the pull rod 202, and the bottom of the pull rod 202 is rotatably connected to the pressing rod 205 through a first bearing 204. The bottom of the pressing rod 205 is provided with a locking tooth 206.

[0026] In this embodiment, the cable 4 is wound around the outside of the cable reel 302 once, and the cable 4 is pulled out from the other side of the cable channel 103. If the cable 4 is too loose, the handle 306 is turned clockwise, which drives the rocker arm 305 to rotate. At the same time, the ratchet 301 and the cable reel 302 rotate clockwise, so that the cable 4 is wound around the cable reel 302 multiple times until the cable 4 is taut. When the handle 306 is stopped, the ratchet 301 rotates counterclockwise, and the locking teeth 206 lock the ratchet teeth around the ratchet 301, fixing the ratchet 301 and preventing the cable 4 from loosening due to the counterclockwise rotation of the ratchet 301. This ensures that the cable 4 can remain taut in various complex environments and improves the transmission performance of the cable 4.

[0027] like Figures 1 to 3 As shown, the protective component 1 includes a protective cover 101, with a mounting groove 102 provided at the top inside the protective cover 101, and a cable channel 103 provided at the middle position of the protective cover 101.

[0028] like Figures 1 to 3 As shown, the end of the cable reel 302 away from the ratchet 301 is rotatably connected to the fixing rod 304 via the second bearing 303, and the other end of the fixing rod 304 is fixedly connected to the protective cover 101.

[0029] In this embodiment, the second bearing 303 allows the cable reel 302 to rotate while the fixing rod 304 fixes the cable reel 302.

[0030] like Figures 1 to 3 As shown, the locking tooth 206 engages with and rotates with the ratchet teeth around the ratchet 301.

[0031] In this embodiment, the locking tooth 206 engages with and rotates with the ratchet tooth, which helps to prevent the ratchet 301 from rotating counterclockwise and causing the cable 4 to loosen and bend, ensuring that the cable 4 can remain taut in various complex environments.

[0032] like Figures 1 to 3 As shown, the top of the interior of the protective cover 101 is provided with a threaded hole, and the threaded groove is matched and threadedly connected to the external thread on the top of the pull rod 202.

[0033] In this embodiment, the threaded hole is matched and threadedly connected to the external thread on the top of the pull rod 202. To prevent the ratchet 301 from generating an upward force when it rotates counterclockwise, the retaining tooth 206 is lifted up, thus playing a fixing role.

[0034] like Figures 1 to 3 As shown, a handle 306 is provided on the side of the rocker arm 305 away from the cable reel 302.

[0035] In this embodiment, the handle 306 is designed to facilitate rotation by the operator, enabling rapid operation.

[0036] Working principle: In use, first pass the cable 4 through one side of the cable channel 103 and wrap it around the outside of the cable drum 302. Then, wrap the cable 4 around the cylinder 104 in reverse and pull it out from the other side of the cable channel 103. If the cable 4 is too loose, turn the handle 306 clockwise. Since the handle 306 is fixedly connected to the rocker arm 305, it drives the rocker arm 305 to rotate, which in turn drives the ratchet 301 and the cable drum 302 to rotate clockwise. This causes the cable 4 to be wound around the cable drum 302 multiple times until the cable 4 is taut. When you stop turning the handle 306, the ratchet 301 rotates counterclockwise. The locking teeth 206 lock the ratchet teeth around the ratchet 301, fixing the ratchet 301 and preventing the cable 4 from becoming too loose due to the counterclockwise rotation of the ratchet 301. This ensures that the cable 4 can remain taut in various complex environments, which is convenient for wiring construction, reliable operation, and improves the transmission performance of the cable 4.

[0037] When it is necessary to loosen cable 4, pull the handle 201, which moves the lever 202 upward and the clamping rod 205 in the same direction. The upward movement of the clamping rod 205 compresses the spring 203, causing it to deform. At the same time, the locking teeth 206 at the bottom of the clamping rod 205 move upward and disengage from the ratchet teeth around the ratchet 301. The ratchet 301 drives the cable reel 302 to rotate counterclockwise, and the cable 4 rotates counterclockwise, loosening the cable 4 to the desired position. Stop pulling the handle 201, and the spring 203 returns to its original position under the action of elastic potential energy. At the same time, it pushes the clamping rod 205, causing the locking teeth 206 to engage with the ratchet teeth around the ratchet 301, preventing it from continuing to rotate counterclockwise and preventing the cable 4 from becoming too loose. This facilitates positioning during subsequent maintenance, reduces engineering and time costs, enhances the flexibility of the cable 4, makes it easier to adjust, extends its service life, and meets diverse industrial needs.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
