Description

Technical Field

[0001] The utility model relates to the technical field of low-voltage electric wires, and more particularly to a low-voltage electric wire tightening device. Background Art

[0002] Low-voltage wire tensioners play a crucial role in modern power systems. They not only affect the stability and safety of power lines, but are also directly related to the operational efficiency of the power system and the normal order of people's lives. Low-voltage wire tensioners are mechanical devices specifically designed to tighten and tension low-voltage wires. They play a vital role in the installation and maintenance of power transmission and communication lines, as well as various electrical equipment. They not only ensure that wires are securely fixed to their supports but also effectively prevent them from loosening or falling due to external factors, thereby ensuring the safe and stable operation of the power system.

[0003] Despite the importance of low-voltage wire tensioning devices in power systems, existing technologies still suffer from several drawbacks and deficiencies. First, operational complexity: Some tensioning devices are cumbersome to operate and require specialized personnel for operation and maintenance, which increases both operational and time costs. Second, lack of versatility: Different wire specifications require different types of tensioning devices, resulting in a wide variety of tensioning devices on the market. Users often need to stock multiple models to accommodate varying wire specifications, leading to resource waste and management inconvenience. Third, unadjustable tensioning force: Some tensioning devices cannot adjust the tensioning force during the tensioning process, which can cause wires to be overtightened or overloose, affecting the stable operation of the power system. Fourth, lack of durability: Due to issues such as material quality and processing technology, some tensioning devices have a short service life and are prone to damage and failure, causing unnecessary trouble and losses for users. In other words, traditional tensioning devices suffer from complex operation, poor tensioning effectiveness, and insufficient safety, making them difficult to meet the efficiency, safety, and stability requirements of modern power systems. Therefore, innovative design and optimization of low-voltage wire tensioning devices are particularly important. Utility Model Content

Figures 1-14 , is a schematic diagram of the structure of the low-voltage wire tightening device of the utility model. Figure 1 As shown, in the low-voltage electric wire tightening device provided in the first embodiment of the present invention, it at least includes: a tightening device 1, a bracket 2, an adjusting mechanism 3 and a locking device 4. The tightening device 1 is fixedly connected to the bracket 2 through a card slot to ensure that the tightening device 1 can be stably fixed on the bracket 2 during operation, reducing loosening or displacement caused by vibration or external force; the adjusting mechanism 3 is integrated inside the bracket 2, and adjusts the angle and position of the tightening device 1 by rotation or sliding, so as to adapt to the tightening requirements of wires of different lengths and diameters; a linkage design is adopted between the locking device 4 and the tightening device 1. When the tightening device 1 reaches the preset tightening force, the locking device 4 is automatically locked to prevent the wire from loosening and ensure the stability of the wire under bad weather or external force.

[0032] To ensure secure connection, the tensioner 1, bracket 2, adjustment mechanism 3, and locking device 4 can be equipped with fasteners and connectors, such as bolts, nuts, and pins, as needed. These connectors ensure the stability and reliability of the components, enabling the tensioner to function properly in a variety of environmental conditions. The tensioner 1, bracket 2, adjustment mechanism 3, and locking device 4 constitute the core components of the low-voltage power line tensioner, and together they form an efficient and stable tensioning system.

[0033] The tensioner 1, as the core component, provides the force required to tighten the wires. Its internal mechanical structure, including a spiral rod and gears, converts rotational motion into linear motion, thereby tightening the wires. The tensioner 1 incorporates a spring and gear mechanism. Rotating or pulling the operating lever generates a continuous tensioning force. When the operating lever is pulled or rotated, the gear mechanism compresses the spring, creating a tightening effect.

[0034] The bracket 2 is the installation base of the tensioner 1 and can be made of a solid metal material to ensure its load-bearing capacity and stability. In specific implementation, the bracket 2 is provided with a mounting hole to facilitate the fixing of the tensioner 1.

[0035] The adjustment mechanism 3 is used to adjust the tightness of the tensioner 1 to adapt to wires of different diameters and materials. By rotating the adjustment knob or lever, the internal mechanical structure of the tensioner 1 can be fine-tuned.

[0036] The locking device 4 is used to lock the wire tensioner 1 after the wire reaches the desired tightness to prevent it from loosening. Common locking devices 4 include bolt locking and ratchet locking.

[0037] The tensioner 1 is the power source for the entire device and is bolted to the bracket 2. Bracket 2 is made of high-strength material, providing excellent load-bearing capacity and stability. The adjustment mechanism 3 is connected to the tensioner 1 and adjusts the tension of the wires through rotation or sliding. The locking device 4 is connected to the adjustment mechanism 3 via a snap or threaded connection, ensuring that the wires do not loosen during tensioning. This connection method not only ensures stability and reliability between the components but also makes the entire device easy to install and maintain.

[0038] In specific implementation, the locking device 4 is provided with a locking tongue, and the wire tensioner 1 is provided with a locking groove. When the wire tensioner 1 reaches a preset tightening force, the locking tongue automatically extends and cooperates with the locking groove to lock the wire.

[0039] In order to achieve double locking, the locking device 4 can be provided with a buckle or a thread locking device 4. The locking device 4 can also be provided with an anti-loosening device.

[0040] The anti-loosening device includes an anti-loosening piece, an automatic adjustment mechanism 3 and a locking indicator. The anti-loosening piece is attached to the surface of the wire to increase the friction between the wire and the locking device 4, thereby effectively preventing the wire from loosening; the automatic adjustment mechanism 3 automatically adjusts the clamping force of the anti-loosening piece according to the tightness of the wire to ensure that the wire is always in the best tightening state; the locking indicator displays the working status of the locking device 4. When the wire is successfully locked, the locking indicator will send an obvious signal to facilitate the operator's confirmation.

[0041] Traditional tensioning devices are often complex and difficult to operate. This device, however, features a simple and clear structural design, making installation and commissioning much simpler and faster. Furthermore, the connections between components have been optimized, improving the stability and reliability of the device.

[0042] Traditional tightening devices often only have a single adjustment mechanism for tension. This device, however, features an innovative design that not only allows for rapid tightening but also allows for precise control of tension through fine-tuning. This design improves work efficiency while ensuring tension quality.

[0043] Traditional locking devices often use a single buckle or thread, which is easy to loosen or damage. The locking device of this device adopts a double locking design, that is, an anti-loosening device is added on the basis of the buckle or thread, effectively preventing the wire from loosening during operation.

[0044] The operating principle of this low-voltage wire tensioner is based primarily on the principles of mechanics and mechanical transmission. To tighten the wire, the operator first adjusts the tensioner's position using an adjustment mechanism, bringing it into contact with the wire. Then, by manipulating the tensioner, the wire is subjected to a certain tension. This tension stretches the wire and secures it to the bracket. At this point, a locking mechanism automatically locks the wire in place, preventing it from loosening.

[0045] During the tightening process, the adjustment mechanism will make fine adjustments according to the tightness requirements of the wires to ensure that the wires reach the optimal tightness state. At the same time, the bracket will also adjust according to the direction and position of the wires to ensure the stability and safety of the wires.

[0046] The working principle of the tensioner is as follows: the tensioner uses a high-strength spring and a precision gear mechanism inside. By rotating or pulling the operating lever, a continuous tensioning force is generated. When the operating lever is pulled or rotated, the gear mechanism drives the spring to compress, producing the tensioning effect.

[0047] The adjustment mechanism works by changing the relative position between the tensioner and the bracket to precisely control the wire tension. Users can adjust the tensioner's angle and position to achieve optimal tensioning based on the actual wire conditions by rotating or sliding the adjustment mechanism.

[0048] How the locking device works: When the tensioner reaches the preset tension, the locking tongue in the locking device automatically extends and engages the locking groove on the tensioner to lock the wire. This automatic locking function effectively prevents the wire from loosening due to inclement weather or external forces, ensuring stable operation of the power system.

[0049] During the entire working process, all components work together and cooperate with each other to achieve fast, stable and safe tightening of the wires.

[0050] The utility model has the following beneficial effects through the design of the above embodiments:

[0051] First, it is easy to operate. The integrated adjustment mechanism and automatic locking device greatly simplify the operation process, reduce the difficulty of operation and improve work efficiency.

[0052] Secondly, the tightening effect is good. The tightening device adopts high-strength spring and precision gear mechanism, which can generate stable and long-lasting tightening force to ensure the stability of the wire in various environments.

[0053] Third, high safety: the automatic locking device can effectively prevent the wires from loosening and reduce the risk of safety accidents caused by wires falling off;

[0054] Fourthly, the device has strong adaptability. Through the flexible adjustment of the regulating mechanism, the device can adapt to the tightening requirements of wires of different lengths and diameters, thereby improving the versatility and practicality of the equipment.

[0055] While the present invention has been described with reference to specific embodiments, those skilled in the art will appreciate that various modifications and equivalents may be made without departing from the scope of the present invention. Furthermore, numerous modifications may be made to adapt the present invention to specific applications without departing from its scope. Therefore, the present invention is not limited to the specific embodiments disclosed herein but encompasses all embodiments falling within the scope of the claims.
