[0002] The core value of anti-loosening clamps is to use mechanical structures to combat the risk of loosening, thereby reducing line faults caused by connection failures at the source. Their application scenarios cover power, communication, transportation and other fields. They are especially important for ensuring safety and efficiency in outdoor, vibrating, complex environments or lines with extremely high reliability requirements.

[0003] The existing device aligns the drain clamp with the position of the wire to be connected, rotates the threaded rod to drive the clamp jaws to open, places the wire into the appropriate position in the jaws, rotates the threaded rod again to close the jaws, and at the same time, another wire is put on the other end. The anti-loosening structure automatically locks, and then the hanging ring is controlled by the insulating rod to lock it, ensuring that the clamp and the wire are tightly connected.

[0004] Current devices struggle to adapt to various wire specifications, automatically adjust clamping force and contact area to fit different wire diameters, and achieve a tight fit regardless of wire thickness. This leads to risks of wire overheating and loosening, reduces wire lifespan, and increases equipment operating costs. Utility Model Content

[0018] 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.

[0019] Reference Figure 1 - Figure 4 The present invention provides an embodiment of a wire clamp with a locking mechanism, comprising a wire clamp body 1, wherein a threaded rod 8 is threadedly connected to the inner wall of the wire clamp body 1, a connecting nut 6 and a connecting block 9, the rotational motion of the nut 6 is converted into the linear motion of the connecting block 9, and the locking force is transmitted; one end of the threaded rod 8 is rotatably connected to the connecting block 9, and a locking component is provided inside the connecting block 9; The locking assembly includes a connecting rod 13, which, when pushed backward, causes the connecting plate 14 to retract. The connecting rod 13 is disposed on the inner wall of the connecting block 9, and the connecting plate 14 is fixedly connected to the outer wall of the connecting rod 13. The connecting rod 13 and the clamping block 16 retract inward under the guidance of the groove inside the connecting block 9, and the clamping block 16 retracts through the change of angle. One end of the connecting plate 14 is rotatably connected to a rotating shaft 15, and the rotating shaft 15 is rotatably connected to the clamping block 16. Driven by 14, it retracts inward to fit the diameter of the wire and achieve tight clamping. A slider 12 is fixedly connected to the outer wall of the clamping block 16. A support plate 23 is fixedly connected to one end of the connecting rod 13. A spring 25 is fixedly connected to the upper surface of the connecting block 9. A connecting rod 24 is fixedly connected to the inner wall of the support plate 23. A pressing block 11 is fixedly connected to one end of the spring 25. A locking block 18 is fixedly connected to the lower surface of the pressing block 11. A locking groove 17 is opened on the upper surface of the connecting block 9.

[0020] Specifically, the operator holds the anti-drop wire clamp, aligns it with the wire to be connected, and rotates the nut 6. Through the transmission of the threaded rod 8, the connecting block 9 is pulled outwards, opening the clamp. After placing the wire in the appropriate position in the clamp, the nut 6 is rotated in the opposite direction, pushing the connecting block 9 inwards to press the wire, initially locking the wire within the clamp body 1. Next, one end of the pressing block 11 is pressed, the spring 25 contracts, and the other end of the pressing block 11 is lifted by the connecting rod 24, causing the locking block 18 to disengage from the slot 17 of the connecting block 9. At this time, the connecting rod 13 is pushed backwards, and the connecting plate 14 retracts inwards along the guide groove inside the connecting block 9. The clamping block 16, with the angle of the connecting plate 14 decreasing, retracts inwards under the guidance of the slider 12 until it fits the wire diameter, closing and locking the clamp. Then, the locking block 18 is inserted into the slot 17 for fixation, and the pulling block 22 is pulled. Through the clamping ring 20, the elastic clamp 19 retracts and locks the threaded rod 8, completing the secondary locking.

[0021] Reference Figure 1 - Figure 6One end of the threaded rod 8 is fixedly connected to a nut 6. A connecting shell 7 is fixedly connected to the outer wall of the clamp body 1. An elastic clamp 19 is fixedly connected inside the connecting shell 7. A clamping ring 20 is sleeved on the outer wall of the elastic clamp 19. A connecting block 21 is fixedly connected to the outer wall of the clamping ring 20. A pulling block 22 is fixedly connected to one end of the connecting block 21. A rotating shaft 10 is rotatably connected to the inner wall of the clamp body 1. A self-locking pressure plate 2 is rotatably connected to one end of the rotating shaft 10. By rotating the rotating shaft 10, the wire to be connected can be automatically locked in the clamp body 1, realizing quick and automatic wire fixing. The outer wall of the slider 12 is slidably connected to... Inside the connecting block 9, the inner wall of the clamp body 1 is threaded with a threaded rod 4. One end of the threaded rod 4 is fixedly connected to a pressure plate 5, and the other end of the threaded rod 4 is fixedly connected to a lifting ring 3 for the insulating rod to hang on, so that the operator can operate the clamp through the insulating rod, such as adjusting the position or rotating it to drive the pressure plate 5 to clamp the wire, ensuring the safety of remote operation. The connecting rod 13 is set inside the connecting block 9, the clamping ring 20 is set inside the connecting shell 7, the inner wall of the elastic clamp 19 is attached to the outer wall of the threaded rod 8, the inner wall of the pressing block 11 is rotatably connected to the outer wall of the connecting rod 24, and the support plate 23 is set on the outer wall of the connecting block 9.

[0022] Specifically, after hanging the other end of the clamp body 1 on the wire to be connected, the self-locking pressure plate 2 rotates through the rotating shaft 10 to automatically lock the wire. The hanging ring 3 is hung with an insulating rod, the pressure plate 5 is adjusted to align with the wire, and the hanging ring 3 is rotated to make the pressure plate 5 clamp the wire. During operation, the clamp and the wire maintain a stable connection, ensuring that the current is safely diverted to other lines or equipment through the drain clamp.

[0023] Working principle: When the anti-drop wire clamp is needed, the operator holds the anti-drop wire clamp, aligns the clamp with the wire to be connected, and rotates the nut 6 to bring out the connecting block 9 through the threaded rod 2 8. After placing the wire into the appropriate position in the clamp, rotate the nut 6 in the opposite direction to push the connecting block 9 inward and compress the wire, locking the wire in the clamp body 1. Then, by pressing one end of the pressing block 11, the spring 25 contracts, and the other end of the pressing block 11 is lifted by the force of the connecting rod 2 24. The locking block 18 connected to the lower surface of the pressing block 11 disengages from the slot 17 in the connecting block 9. At this time, the connecting rod 13 can be pushed backward. During the backward pushing of the connecting rod 13, the connecting plate 14 continuously contracts inward due to the guide of the slot inside the connecting block 9. The clamping block 16 connected to the other end of the connecting plate 14 continuously contracts inward due to the angle of the connecting plate 14 continuously decreasing. The clamping blocks 16 on both sides are continuously guided by the slider 12. The clamping blocks 16 on both sides conform to the diameter of the conductor when the clamping blocks 16 retract to a certain distance. The clamping opening closes perfectly to lock the conductor and ensure a tight connection between the clamp and the conductor. Then, the locking block 18 is aligned with the slot 17 on the upper surface of the connecting block 19 to achieve fixation. Then, the pulling block 22 is pulled to use the clamping ring 20 to retract the elastic clamp 19 and lock the threaded rod 28, thereby achieving a secondary locking effect to prevent the threaded rod 28 from loosening under external force. The other end of the clamp body 1 is hung on the wire to be connected. The self-locking pressure plate 2 automatically locks the wire to be connected in the clamp body 1 by rotating the rotating shaft 10. The pressure plate 5 is aligned with the conductor by hanging the hanging ring 3 with the insulating rod. Then, the pressure plate 5 clamps the conductor by rotating the hanging ring 3 with the insulating rod. During operation, a stable connection is maintained between the clamp and the conductor, so that the current can be safely diverted to other lines or equipment through the drain clamp.
