[0027] In order to make the purpose, technical scheme and advantage of the embodiment of the present disclosure more clear and clear, the embodiment of the present disclosure is further described in detail below, and the illustrative embodiment of the embodiment of the present disclosure and its description are only used to explain the embodiment of the present disclosure, and not as the limitation of the embodiment of the present disclosure.

[0028] As Figure 1 Indicated, a kind of tight line device for distribution circuit of the application includes tight line arm 1, adjustable chuck 2, fixed seat 3 and adjusting screw 4.The tight line device can provide effective tight line and clamping function for different electric wires, applicable to the electric wire installation operation of various diameters and types.

[0029] Tight line arm 1 is used to firmly hold electric wire, and provides required clamping force by its structure.Secondly, adjustable chuck 2 is provided on tight line arm 1.This part is mainly used to contact with electric wire and adapt to different specifications of electric wire by changing its size.Fixed seat 3 for overall installation and fixation is arranged at the bottom of the device, to ensure that the whole device can maintain stable position in actual working environment.In addition, adjusting screw 4 connected to adjustable chuck 2 and cooperated with it is also included, adjusting screw 4 is used to adjust the opening size of adjustable chuck 2 by adjusting fixed position, to adapt to different size cables.

[0030] Specifically, tight line arm 1 is made of high-strength alloy material to cope with larger tension and torsional force, and the surface is subjected to corrosion-resistant treatment.Adjustable chuck 2 is slidably arranged on tight line arm 1, and includes several groups of metal plates that can adjust the opening size or shape to ensure close fit to the line to be processed.For fixed seat 3, some mounting screws or other mechanical fittings are usually provided, so that it can be firmly fixed on the support, providing necessary safeguard measures for subsequent operation.As for adjusting screw 4, it is made of high-quality steel and subjected to precision machining to ensure smooth operation experience and long service life.In addition, a manual wheel is also configured to help users more conveniently rotate and operate tight line arm 1 to achieve the purpose of tight line.

[0031] When different diameters and types of wires need to be dealt with, each slot 5 of the multi-slot adjustable clamp head 2 of the present application has different geometric parameters to match the corresponding type of cable cross-sectional shape and outer diameter size, so as to reliably grasp and maintain appropriate pressure distribution on the target site; then by means of flexible adjustment function, the user only needs to slightly twist the adjusting screw 4 to quickly and accurately set the ideal gap size suitable for the specific wire. In this way, the device in the present application not only realizes efficient fastening, but also can adapt to a wide range of changes, effectively improving the construction efficiency and safety.

[0032] In one embodiment, the line tightening arm 1 can adjust its bending angle, which enables the clamp head at the end of the line tightening arm 1 to better fit various specifications and types of wires. By adjusting the bending angle of the line tightening arm 1, not only the flexibility of clamping is increased, but also fine tuning can be made according to the specific characteristics of the wire, such as thickness and outer surface texture, to ensure that the best clamping force can be achieved every time the line is tightened. In order to ensure normal function in various working environments, the design allows the user to quickly and accurately adjust the angle of the line tightening arm 1 according to different working conditions.

[0033] This adjustability is mainly achieved by the connection between the line tightening arm 1 and the clamp head. Specifically, the line tightening arm 1 is installed on the fixed seat 3 and achieves the angle adjustment function through a movable joint. In addition, the clamp head is connected to one end of the line tightening arm 1 and can be adaptively adjusted through a flexible linkage mechanism. For example, in one embodiment, the bending angle can be freely changed by a rotary hinge provided between the line tightening arm 1 and the clamp head. The rotary hinge has a locking function, which is unlocked when adjustment is needed and the hinge is turned to change the angle. After the angle is adjusted to the right position, the position is locked again to stabilize the posture of the clamp head, ensuring that a constant effective action is maintained during the entire line tightening process.

[0034] Further, in an actual operation case, when facing a wire with a larger diameter and irregular shape, the technician can adjust the angle of the line tightening arm 1 to the appropriate state through the adjusting screw 4, so that the clamp head closely fits and firmly holds the wire, without causing excessive compression or slipping phenomenon. This feature gives the line tightening device a wider range of applications and higher operation convenience and safety. Through the above method, the optimized use of the line tightening arm 1 in different scenarios is realized, meeting the changing needs in power distribution circuit construction.

[0035] In one embodiment, referring to Figure 2 and Figure 3The design of the wire tightening device for power distribution circuit in the present application is particularly provided with elastic clamping pieces 6 on the wire tightening arm 1. The elastic clamping pieces 6 are located on one side of the wire tightening arm 1 and form a clamping cavity with the wire tightening arm 1, which is used to firmly clamp wires of various diameters. This design not only improves the ability of the device to adapt to different wire specifications, but also further improves the safety and stability of the wire tightening operation. Through the close cooperation between the elastic clamping pieces 6 and the wire tightening arm 1, the wire tightening device can firmly clamp various wires without slipping, thereby ensuring the effective progress of the entire wire tightening process.

[0036] For example, the elastic clamping pieces 6 can be made of high-molecular materials with good elasticity or metal spring pieces, and their two ends are fixed to the inner side of the wire tightening arm 1 and are kept in a tension state through a certain pre-compression force. When the wire enters, it will trigger the clamping pieces to contract inward to generate a counteracting force, forming a closed and compact clamping space. At the same time, the elastic recovery performance of the elastic clamping pieces 6 enables them to still have good clamping performance after multiple uses, and they will not lose their original characteristics due to long-term compression, ensuring the consistency and reliability of each operation.

[0037] In one embodiment, referring to Figure 4 The adjustable chuck 2 of the wire tightening device for power distribution circuit in the present application is provided with a rubber pad 7. This design makes the rubber pad 7 match the shape of the adjusting groove 5. The rubber pad 7 is installed inside the adjustable chuck 2, tightly adheres to the adjustable chuck 2, and maintains the same shape as the adjusting groove 5, thereby increasing the friction when clamping wires of different diameters. The rubber pad 7 can tightly adhere to wires of various shapes and diameters through the elastic deformation of its material, ensuring the stability of the wires while avoiding the slipping problem that may be caused by traditional materials. Since the rubber material has good elasticity and wear resistance, it not only improves the firmness of the device to the wire, but also reduces the damage to the surface of the wire.

[0038] Specifically, in an exemplary implementation, the rubber pad 7 with appropriate thickness and material properties is inlaid or bonded to form an integral structure with the inner wall of the adjustable chuck 2. In actual operation, after the wire to be fixed is placed in the corresponding adjusting groove 5, the adjusting screw 4 is adjusted to close the adjustable chuck 2 and tightly adhere to the wire. At this time, the rubber pad 7 is slightly elastically deformed due to pressure, thereby increasing the contact area and surface friction. This method is not only suitable for wire fixing requirements of different diameters, but also shows good durability in long-term use. This design optimizes the stability and safety of the wire fixing process.

[0039] In one embodiment, the adjusting screw 4 of the wire tightening device for power distribution circuit in the present application is provided with a fine adjustment knob 8 (see Figure 4), the opening and closing distance of the adjustable clamp head 2 can be finely adjusted through the fine adjustment knob 8 to fix the adjustable clamp head 2 at different positions of the wire tightening arm 1, thereby more accurately adapting to wires of different diameters. This design makes the operation more flexible and accurate, especially when dealing with wires of different diameters or special requirements. The adjustment screw 4 is connected to the adjustable clamp head 2, and the fine adjustment knob 8 is installed on the adjustment screw 4. The user can accurately control the specific position of the adjustable clamp head 2 by slightly rotating the fine adjustment knob 8.

[0040] Further, the wire tightening arm 1 is used to provide clamping force and necessary tightening effect on the wire, ensuring stable clamping of the wire without slipping. The fixed seat 3 is used for safe and stable installation of the entire wire tightening device, ensuring that the device can maintain a fixed posture and angle during use. The adjustment screw 4, as the main component for adjusting the position of the adjustable clamp head 2, has the fine adjustment knob 8 installed on it, which enhances the accuracy of the system and allows the user to make more granular adjustments according to actual needs.

[0041] For example, when the operator needs to apply the wire tightening device to a wire that is slightly thicker than the conventional one but still within the adjustable range, the operator can first preliminarily set the adjustable clamp head 2 to a roughly appropriate position, and then use the fine adjustment knob 8 to fix this position until the adjustable clamp head 2 can be exactly clamped into the target wire without damaging the wire surface and achieving the required clamping tightness.

[0042] In one embodiment, the fixed seat 3 of the wire tightening device for power distribution circuits of the present application is provided with positioning holes 9. The number and position of the positioning holes 9 can be flexibly adjusted according to the installation environment of the wire tightening device. This design ensures stable installation of the wire tightening device in various complex environments and enhances its adaptability. For example, in some cases, the positioning holes 9 on the fixed seat 3 can be arranged in the appropriate position by welding or mechanical processing to match the specific mounting bracket or other fixing structure. Specifically, the positioning holes 9 can be circular or square, and the diameter and spacing can be accurately adjusted according to different support structures to effectively fix the fixed seat 3.

[0043] In a specific example, the positioning holes 9 are manufactured by drilling machines and other processing equipment and distributed at different positions on the surface of the fixed seat 3. By changing the processing program or mold design, the number of positioning holes 9 and their distance from the edge or center of the fixed seat 3 can be easily adjusted. This not only ensures flexibility during installation, but also ensures optimal fixing effect. From a technical implementation perspective, this adjustable positioning hole 9 structure is usually achieved by using a numerical control machine or a template with manual drilling, so that each positioning hole 9 can accurately meet the installation requirements and provide the necessary fixing effect.

[0044] In one embodiment, the fixing base 3 of the wire tightening device for power distribution circuit according to the present application is provided with a magnetic base 10 capable of being adsorbed to an iron power distribution cabinet or support through a magnetic field. This design not only improves the stability and safety of the entire device, but also effectively ensures that the wire tightening device is not easily displaced or loosened during operation.

[0045] Specifically, the magnetic base 10 is usually installed at the bottom of the fixing base 3 and tightly combined with the fixing base 3 to form an integral unit. The main components of the magnetic base 10 include a high-strength magnet and a metal shell responsible for protecting the magnet and providing good mechanical strength and durability. The design of the magnetic base 10 enables the device to be reliably fixed on any work surface containing iron components and can be flexibly moved to other suitable positions for rearrangement as needed.

[0046] For example, the magnet can be made of high-performance rare earth permanent magnet material to enhance its adsorption force and ensure reliability for long-term use. In order to facilitate the installation and removal operation, the magnetic base 10 is also provided with a convenient manual unlocking mechanism or a quick release mechanism. By rotating or sliding a specific component, the state of the magnetic force can be easily adjusted, allowing the wire tightening device to be quickly and firmly attached to the target surface or easily detached, adapting to various complex application requirements.

[0047] In one embodiment, the wire tightening device for power distribution circuit according to the present application is characterized by a threaded connection between the adjusting screw 4 and the adjustable chuck 2. This connection ensures that the adjusting screw 4 and the adjustable chuck 2 are stably connected. The outer diameter of the adjusting screw 4 is designed to be smaller than the inner diameter of the adjustable chuck 2 to ensure smooth relative movement between the two and fixed by screw feeding to control the opening and closing size of the adjustable chuck 2. One end of the adjusting screw 4 is embedded in the inside of the adjustable chuck 2 and tightly engages with the threads inside the adjustable chuck 2, and then is fixed with the wire tightening arm 1, thereby ensuring the position of the adjustable chuck 2 is fixed.

[0048] In one embodiment, the width of the adjusting groove 5 of the adjustable chuck 2 of the wire tightening device for power distribution circuit according to the present application gradually increases from the center to the outside. This design ensures that wires of different diameters can more smoothly enter the appropriate groove and be stably maintained, improving the reliability and efficiency of the wire tightening operation. Specifically, by reasonably designing the structure of the adjusting groove 5, not only does the installation operation become more convenient, but also various sizes of wires can always be in the optimal stress state during use, thereby improving the adaptability and flexibility of the overall equipment.

[0049] To elaborate on this point, it is noted that in this design, the adjustable clamp 2 is located at one end of the tightening arm 1 and is fixed to the fixed base 3 through a connecting structure. The adjustment screw 4 is responsible for adjusting the opening and closing size of the adjustable clamp 2, ensuring that it can be flexibly adjusted according to actual needs. When facing various types and specifications of wires, this unique gradual adjustment groove 5 can significantly improve the effect of wire clamping. Since each adjustment groove 5 expands outward from the inside according to a certain rule, even the thinnest or thickest wire can be properly placed in the appropriate position, ensuring good mechanical fitting performance and stability.

[0050] For example, in one practical application, the gradual change in width can be achieved by changing the angle or curve of the edge of the adjustment groove 5. In addition, a precision machining process can be used when manufacturing the adjustment groove 5 to ensure smooth transitions, ensuring that each adjustment groove 5 can meet the requirements of smooth wire insertion and provide sufficient contact area and support force in the clamped state. This design not only improves work efficiency but also increases the safety factor of the system.

[0051] In one embodiment, the end of the tightening arm 1 of the wire tightening device for power distribution circuits of the present application is provided with a guide wheel 11. The guide wheel 11 is installed at the end of the tightening arm 1 and can provide stable guidance for the wire as it passes through. With this arrangement, the damage that the wire may suffer due to friction or bending during the tightening process can be significantly reduced, thereby improving the safety and reliability of the wire laying process. Specifically, when the wire is introduced from one side of the wire tightening device, it will smoothly wind into the adjustment groove 5 along the trajectory of the guide wheel 11. This design not only optimizes the operation process but also ensures the integrity of the wire.

[0052] The guide wheel 11 is made of wear-resistant material and typically includes a central shaft and a rolling structure around it (see the conical structure in Figure 4 The central shaft is connected to the end of the tightening arm 1 through a bearing, ensuring that the guide wheel 11 can rotate freely. The rolling structure directly contacts and guides the wire, keeping it on the correct path at all times.

[0053] In one embodiment, the fixed base 3 of the wire tightening device for power distribution circuits of the present application is provided with a rotating joint 12 between the tightening arm 1 and the fixed base 3, which allows the tightening arm 1 to rotate within a certain range on the fixed base 3. This structure allows the device to adjust the angle flexibly to meet different wire installation needs. Specifically, by providing this rotating joint 12, more precise operation positioning can be achieved, allowing the device to perform better in various complex working conditions.

[0054] The fixed base 3 is mainly used for stable support and installation of the whole tightening device, and is connected to an external base or support to provide a stable mechanical environment. In order to enable the tightening arm 1 to rotate freely and meet different angle requirements, a rotating joint 12 is arranged at a specific position between the fixed base 3 and the tightening arm 1. The rotating joint 12 is composed of two oppositely matched components: one part is fixed on the fixed base 3, and the other part is connected with the tightening arm 1. The two parts are assembled together through appropriate shaft connection means such as shaft and sleeve components, and the rotating angle range is controlled through a limiting mechanism to prevent the tightening arm 1 from rotating excessively.

[0055] For example, when a spherical joint or other form of hinge is used to realize the rotating function, a bearing, a pin shaft or other parts can be inserted between the fixed base 3 and the tightening arm 1 to ensure smooth and stable rotation under the condition of bearing a large working load. In order to ensure the safety and controllability of the rotating operation, a certain damping or locking device is also introduced in the design to ensure that the tightening arm 1 can be firmly parked at the specified position. At the same time, according to the angle adjustment requirements in actual application, the rotating joint 12 can be equipped with a limiting device to limit the maximum rotation amplitude of the tightening arm 1. This not only guarantees the safety of operation but also improves the work efficiency.

[0056] In actual operation process, when the device is used, first, the tightening device is installed and fixed in a proper position through the fixed base 3. Then, according to the diameter and type of the wire, a suitable adjusting groove 5 is selected, and the wire is placed in the selected adjusting groove 5. The adjustable clamp head 2 adjusts its opening and closing size through the position adjustment of the adjusting screw 4 to ensure that the wire is firmly clamped.

[0057] The above is only a specific embodiment of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art can easily think of various changes or replacements within the technical scope disclosed in the present application, and these should be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
