Abstract
Description
Technical Field
[0001] This invention relates to the field of power line installation equipment technology, and in particular to a bird-proof conductor anti-detachment clip. Background Technology
[0002] In the field of wire and cable installation and fixing technology, post-type porcelain insulators are usually fixed by binding with ordinary copper wire. This method is cumbersome, the binding effect depends on manual experience, and is prone to problems such as loosening and insulation damage. It is difficult to meet the needs of efficient and stable installation in high-altitude operations. With the continuous development of technology, existing technologies have emerged with binding-free locking wire fixing devices. For example, application number 202410574953.2 discloses an anti-loosening buckle, which includes a lower locking part with a clamping arm that clamps the lower locking part onto the insulator; an upper pressure cover that presses and fixes the wire in a groove on the top plane of the insulator; and a connecting part including a first bolt and a second bolt, which are arranged opposite to each other. The first bolt passes through the lower locking part and the upper pressure cover in sequence through the corresponding through holes and is fixed by a nut. One end of the second bolt is hinged to the lower locking part, and the other end is fixed to the upper pressure cover by a nut, effectively replacing the traditional binding method.
[0003] However, the clamping structure and fixing parts of the above-mentioned wire harness fixing clips are designed with fixed dimensions, which can only be used for a single specification of post-type porcelain insulators. They cannot be compatible with post-type porcelain insulators of different sizes and specifications. In actual power distribution engineering applications, they have poor applicability. Not only do they require the stocking of multiple models of clips for different insulator specifications, increasing material and management costs, but they are also prone to problems such as insecure clamping and fixing failure due to size mismatch. This is not conducive to the standardization and large-scale application of overhead line conductor fixing. Summary of the Invention
[0004] To overcome the above-mentioned technical problems, the present invention provides a bird-proof wire anti-detachment clip.
[0005] The technical solution of this invention is: a bird-proof wire anti-detachment clip, comprising: Buckle body; Both swing brackets are mounted on the buckle body; Two sliding blocks are respectively slidably mounted on the two swing frames; Two limiting frames are slidably mounted on the two sliding blocks respectively. The opposing sides of the two limiting frames are provided with arc-shaped grooves, and the opposing sides of the two limiting frames are provided with elastic pads. An adjustment mechanism is provided on the limiting frame, and the adjustment mechanism is used to adjust the gap between the two limiting frames.

[0009] More preferably, the wire harness fastening block has an arc-shaped groove, and the arc-shaped groove of the wire harness fastening block is provided with a plurality of elastic strips evenly distributed therein.
[0010] More preferably, the buckle body is slidably provided with two first sliding frames, the first sliding frames are fixedly connected to the buckle body with a tension spring, the swing frame is rotatably connected to the buckle body, and the swing frame is fixedly connected to the buckle body with a torsion spring. The swing frame has multiple limiting holes, and the first sliding frame is used to be inserted into the corresponding limiting hole.

Beneficial effects
[0014] 1. Significantly improved versatility and adaptability: The first and second threaded rods can be continuously and steplessly adjusted, and can be adapted to the opening and closing angle of the swing frame, the sliding stroke of the sliding block and the clamping distance of the limit frame. It can firmly clamp the column-type porcelain insulators with different neck diameters and specifications, making up for the shortcomings of traditional devices that can only adapt to a single specification of insulator. The flexibility and versatility of on-site installation are significantly enhanced.
[0015] 2. Flexible and efficient installation, adaptable to multiple operation scenarios: The equipment supports two installation modes: manual adjustment and fixing, and automatic clamping in the air.

[0016] 3. Securely fixed and highly stable in operation: The dual structure of the limit frame and buckle body ring-locking and the first sliding frame and limit hole mechanical self-locking can resist external impacts such as wind vibration and conductor swaying, and prevent problems such as loosening of adjustment parts, displacement of swing frame, and loosening and slippage of conductors, ensuring long-term stable fixation of conductors and insulators.
[0017] 4. Significantly extended service life: The threaded locking is achieved by tightening bolts, which avoids loosening and wear of the adjustment structure; the elastic components buffer the impact of the conductor shaking, reduce the damage caused by the conductor's reciprocating bending and hard contact, and at the same time reduce the probability of equipment failure, thus extending the service life of both the equipment and the conductor.

Detailed Implementation
[0020] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0021] In this document, terms such as "upper," "lower," "inner," and "outer" are established based on the positional relationships shown in the accompanying drawings. Depending on the drawings, the corresponding positional relationships may also change. Therefore, they should not be interpreted as an absolute limitation on the scope of protection. Moreover, relational terms such as "first" and "second" are only used to distinguish one component from another that has the same name, and do not necessarily require or imply any such actual relationship or order between these components. Example 1
[0022] Bird-proof cable anti-detachment clip, see reference. Figures 1-3 As shown, the main body 1 of the buckle serves as the core base for overall installation and support. Two swing frames 2 are symmetrically distributed on the buckle body 1. Two sliding blocks 3 are respectively mounted on the two swing frames 2 in a sliding fit, and can slide in a directional manner along the length of the swing frame 2. Two limiting frames 4 are respectively slidably set on the two sliding blocks 3. The inner sides of the two limiting frames 4 are provided with arc-shaped grooves that are adapted to the shape of the column-type porcelain insulator. Elastic pads are provided on the clamping surfaces of the two limiting frames 4. The elastic pads can improve the clamping friction and protect the porcelain body of the insulator from being scratched. An adjustment mechanism is provided on the limiting frame 4. The adjustment mechanism is used to accurately and stably adjust the clamping gap between the two limiting frames 4 to adapt to insulators of different specifications and sizes.
[0023] Reference Figure 3 As shown, the adjustment mechanism mainly consists of two first threaded rods 5 and two first fastening bolts 501. The two first threaded rods 5 are respectively mounted on the two limit frames 4 in a rotating fit. At the same time, the first threaded rods 5 and the adjacent sliding blocks 3 form a threaded transmission connection. The rod body of the first threaded rod 5 is provided with a horizontal groove, which is convenient to use tools to screw and realize the adjustment operation. The two first fastening bolts 501 are respectively threaded to the limit frames 4. The first fastening bolts 501 can be screwed to abut against the adjacent first threaded rods 5 to realize the positioning and locking of the first threaded rods 5 after adjustment. The swing frame 2 is also rotatably provided with a second threaded rod 6. The second threaded rod 6 and the adjacent sliding block 3 form a threaded transmission fit, which is used to drive the sliding block (3) to slide and adjust along the swing frame 2. The second threaded rod 6 is also provided with a horizontal groove. The swing frame 2 is threadedly connected with a second fastening bolt 601. The second fastening bolt 601 can be screwed to press the adjacent second threaded rod 6 to complete the locking and fixing after the position adjustment of the sliding block 3, and prevent the adjustment part from loosening and shifting.
[0024] Working principle: When using this device to fix the conductor, first loosen the first fastening bolt 501 and the second fastening bolt 601 to release their squeezing constraint on the first threaded rod 5 and the second threaded rod 6, providing free rotation space for subsequent size adjustment and avoiding thread jamming; then rotate the first threaded rod 5 and the second threaded rod 6 to drive the limiting frame 4 to move horizontally along the sliding block 3 and the sliding block 3 to move vertically along the swing frame 2. Through the coordinated adjustment of the horizontal and vertical dimensions, the two limiting frames 4 are adjusted to the extreme position of separation, expanding the clamping opening to adapt to the shape and size of the insulator.
[0025] The buckle body 1 is then placed on the insulator, pressing the wire on the insulator to achieve initial positioning of the wire and prevent wire displacement from affecting the fixing effect. Then, the first threaded rod 5 and the second threaded rod 6 are rotated in the opposite direction, causing the two limiting brackets 4 to move towards each other and clamp the insulator together with the buckle body 1, forming a ring-type locking structure to ensure that the wire and the insulator are relatively fixed, completing the limiting and fixing of the wire. Finally, the first fastening bolt 501 and the second fastening bolt 601 are tightened to press the first threaded rod 5 and the second threaded rod 6 respectively. The thread is locked by axial extrusion force, which prevents the adjustment parts from loosening under the action of external forces such as wind vibration and wire swaying, ensuring long-term stable operation of the equipment and extending its service life.
[0026] During installation and adjustment, the first threaded rod 5 and the second threaded rod 6 can achieve continuous stepless size adjustment, synchronously adapting to the opening and closing angle of the swing frame 2, the sliding stroke of the sliding block 3, and the clamping distance of the two limit frames 4. This allows the buckle body 1 and the limit frame 4 to fit precisely and firmly clamp post-type porcelain insulators of different neck diameters and specifications. There are no gear limitations, and the compatibility range is fully covered. This solves the defect of traditional fixing devices that can only adapt to a single specification of insulator, greatly improving the universal compatibility of the equipment and the flexibility of on-site installation. Example 2
[0027] Based on Example 1, referring to Figures 2-4As shown, this buckle is also equipped with a wire fastening and linkage unlocking assembly, including a wire harness fastening block 7 and multiple sets of springs 701. The wire harness fastening block 7 is slidably mounted on the buckle body 1. Multiple springs 701 are fixedly connected between the buckle body 1 and the wire harness fastening block 7 to provide continuous elastic preload for the wire harness fastening block 7. An elastic pad is provided at the bottom of the wire harness fastening block 7 to ensure that the wire harness fastening block 7 applies different squeezing forces to the wire. An arc-shaped groove adapted to the outer diameter of the wire is provided on the wire harness fastening block 7, and multiple elastic strips are evenly distributed in the arc-shaped groove to flexibly clamp the wire and protect the wire insulation layer from wear. Two first sliding frames 8 are slidably arranged on the buckle body 1. A tension spring 801 is fixedly connected between the first sliding frame 8 and the buckle body 1. The tension spring 801 provides the first sliding frame 8 with a tension force for automatic reset. The swing frame 2 is rotatably connected to the buckle body 1. A torsion spring 802 is fixedly connected between the swing frame 2 and the buckle body 1. The torsion spring 802 provides the swing frame 2 with a torque force for automatic clamping. Multiple limiting holes 9 are opened on the swing frame 2. The first sliding frame 8 can be inserted into the corresponding limiting hole 9 to lock and position the rotation angle of the swing frame 2. An inclined surface 702 is formed on the wire harness fastening block 7. The inclined surface 702 is used to squeeze the corresponding first sliding frame 8 and trigger the limiting unlocking action of the swing frame 2.
[0028] Working principle: When using this equipment to fix the energized conductor, first adjust the swing frame 2 to be horizontal, so that the first sliding frame 8 is inserted into the corresponding limiting hole 9 to achieve the pre-position, and fix the initial posture of the swing frame 2 to provide a basis for accurate high-altitude alignment; then rotate the first threaded rod 5 and the second threaded rod 6 to complete the stepless adjustment so that the equipment can be adapted to the insulator specifications.
[0029] After adjustment, the buckle body 1 is placed above the insulator with the help of the insulating support rod, which meets the safety requirements for high-altitude live operation. No personnel need to climb the pole to operate. The wire harness fastening block 7 first contacts the insulator and applies downward pressure to the buckle body 1, so that the wire harness fastening block 7 moves upward relative to the buckle body 1 and compresses the spring 701. The spring 701 stores energy to provide power for subsequent reset, and at the same time triggers the linkage unlocking mechanism. The inclined surface 702 simultaneously squeezes the first sliding frame 8, so that it is disengaged from the limiting hole 9 to release the limit of the swing frame 2.
[0030] Under the torsion of the torsion spring 802, the swing frame 2 swings vertically and automatically completes the clamping action by relying on the elastic torsion, without the need for manual adjustment, which drives the sliding block 3 and the limiting frame 4 to engage in the gap of the insulator. After the pressure and insulating support rod are removed, the spring 701 pushes the buckle body 1 to move upward, which in turn drives the limiting frame 4 to clamp the insulator. The elastic restoring force is used to achieve automatic locking, which simplifies the high-altitude operation steps and completes the wire fixing. During the upward movement of the buckle body 1, the tension spring 801 pulls the first sliding frame 8 to reset and insert into another limiting hole 9, which relocks the swing freedom of the swing frame 2, forming a mechanical self-locking structure, preventing the swing frame 2 from loosening and shifting during equipment operation, and ensuring the reliability of high-altitude installation. Example 3
[0031] Based on Example 2, referring to Figure 2 , Figure 5 and Figure 6 As shown, this buckle also integrates bird protection and sway buffer components, including four elastic plates 10 and four fixing posts 11. The four elastic plates 10 are fixedly connected to the buckle body 1, and the four fixing posts 11 are respectively fixedly installed on the four elastic plates 10. The elastic plates 10 have rectangular holes to enhance their elastic deformation capability. The fixing posts 11 have a two-section structure: a vertical section and an inclined section, which together form a bird-proof isolation barrier to prevent birds from approaching the wire and insulator fixing parts. Two symmetrically distributed fixing blocks 12 are fixedly connected to the buckle body 1. Two second sliding frames 13 are slidably mounted on the fixing blocks 12. A fixing frame 14 is fixedly connected to the elastic plates 10. The second sliding frames 13 slide directionally within the corresponding fixing frames 14. The second sliding frames 13 can compress the wire harness fastening block 7, achieving adaptive secondary clamping reinforcement when the wire sways, preventing the wire from sliding and loosening.
[0032] Working principle: When using this device to fix the wire, first loosen the first fastening bolt 501 and the second fastening bolt 601 to release their squeezing constraint on the first threaded rod 5 and the second threaded rod 6; then rotate the first threaded rod 5 and the second threaded rod 6 to drive the limiting frame 4 to move horizontally along the sliding block 3 and the sliding block 3 to move vertically along the swing frame 2, adjusting the two limiting frames 4 to their respective extreme positions.
[0033] Then, the buckle body 1 is placed on the insulator, so that the buckle body 1 presses the conductor on the insulator. Then, the first threaded rod 5 and the second threaded rod 6 are rotated in the opposite direction, causing the two limit brackets 4 to move towards each other and clamp the insulator together with the buckle body 1, thus completing the limit fixation of the conductor. Finally, the first fastening bolt 501 and the second fastening bolt 601 are tightened so that they press the first threaded rod 5 and the second threaded rod 6 respectively, to prevent the adjustment parts from loosening, ensure stable operation of the equipment, and extend its service life.
[0034] During installation and adjustment, the first threaded rod 5 and the second threaded rod 6 can achieve continuous stepless size adjustment, synchronously adapting to the opening and closing angle of the swing frame 2, the sliding stroke of the sliding block 3, and the clamping distance of the two limit frames 4. This allows the buckle body 1 and the limit frame 4 to fit precisely and firmly clamp post-type porcelain insulators with different neck diameters and specifications, solving the defect of traditional fixing devices that can only adapt to a single specification of insulator, and greatly improving the universality and on-site installation flexibility of the equipment.
