Description

Technical Field

[0001] This utility model relates to the field of tension power line clamps, specifically a power line clamp. Background Technology

[0002] Tension clamps are hardware used to fix wires to withstand wire tension and hang them on tension strings or towers. Tension clamps are mainly used for cornering, splicing, and terminal connections. During the use of tension clamps, the wires need to be restrained to ensure that the wires do not shift due to wind.

[0003] Tension clamps need to be rigidly connected to the pole to ensure stability. During use, the tension clamps will receive vibrations from the pole. Long-term use and vibration can cause the nuts of the tension clamps to loosen, which reduces the U-bolts' fixation of the wires and thus reduces the clamp's tightening effect on the wires. Utility Model Content

[0004] To overcome the problem that the nuts of existing tension clamps may loosen due to vibration after long-term use, this utility model provides a power clamp.

[0005] The present invention adopts the following technical solution.

[0006] A power line clamp includes a clamp head, one end of which is fixed to a mounting base, and the mounting base is provided with a fixed optical axis and a rotatable bolt;

[0007] A clamping block is also provided, which is threadedly connected to the bolt and slidably connected to the optical axis. The clamping block has multiple locking grooves evenly distributed in the vertical direction.

[0008] The mounting base is provided with a locking assembly, which includes a locking block fixed to the mounting base. The locking block has a movable cavity, and a limiting toothed ring is fixed to one end of the movable cavity. A driving core is slidably disposed in the movable cavity. One end of the driving core is provided with a limiting protrusion that meshes with the limiting toothed ring, and the other end of the driving core is provided with an external spline. A driving disk is rotatably disposed in the movable cavity. The driving core passes through the driving disk. A transmission rod is hinged to the driving disk, and a locking rod is hinged to one end of the transmission rod.

[0009] Preferably, the locking block has a groove for restricting the movement of the locking rod in the horizontal direction.

[0010] Preferably, the movable cavity is provided with an ejector spring that brings the drive core closer to the limiting toothed ring.

[0011] Preferably, a clamping head is slidably provided on the inner sidewall of the clamping block, and a clamping spring is provided between the clamping head and the clamping block.

[0012] Preferably, a polygonal mounting hole is provided on one end face of the drive core.

[0013] Preferably, the locking rod has a chamfer at one end near the locking groove.

[0014] The beneficial effects of this utility model are as follows:

[0015] The power line clamp provided by this utility model adopts a design that uses bolts and threaded connections between the clamping block and a sliding guide via a light axis. This structure ensures that the clamping block moves smoothly under the drive of the bolt, generating a uniform and reliable clamping force on the power line. The light axis prevents the clamping block from deflecting or jamming under force, ensuring the stability and reliability of the clamping process, thereby ensuring a secure power line connection and reducing safety hazards caused by loose clamps.

[0016] The clamping block features multiple vertically distributed locking slots. Combined with the locking components on the mounting base, this allows the clamp to be adjusted to fit different power wire diameters. Different locking slots correspond to different clamping diameters, making the clamp suitable for various power wire specifications. This improves the product's versatility and applicability, reducing the inconvenience of needing different clamp sizes during power construction and maintenance.

[0017] The locking assembly, consisting of a limiting toothed ring, limiting teeth, a transmission rod, and a locking rod, reliably locks the position of the clamping block. This locking method utilizes the self-locking characteristics of the mechanical structure to effectively prevent the wire clamp from loosening during long-term use, especially under vibration or external forces. The cooperation of the limiting toothed ring and limiting teeth provides multi-point engagement locking, further enhancing the reliability of the lock. The linkage design of the drive disc, transmission rod, and locking rod employs a force-multiplying mechanism to achieve reliable locking with a small driving force, and the locked state is not easily released, maintaining stability during long-term use.

[0026] The accompanying drawings are for illustrative purposes only and should not be construed as limiting the scope of this patent. To better illustrate this embodiment, some parts in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product.

[0027] It will be understood by those skilled in the art that certain well-known structures and their descriptions may be omitted in the accompanying drawings. The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0028] As attached Figure 1-5 The power line clamp shown includes a clamp head 1, one end of which is fixed with a mounting base 11. The mounting base 11 is provided with a fixed optical shaft 112 and a rotatable bolt 111.

[0029] A clamping block 12 is also provided. The clamping block 12 is threadedly connected to the bolt 111 and slidably connected to the optical axis 112. Multiple locking grooves 121 are evenly distributed in the vertical direction on the clamping block 12.

[0030] A locking assembly is provided on the mounting base 11. The locking assembly includes a locking block 2 fixed to the mounting base 11. The locking block 2 has a movable cavity 21. One end of the movable cavity 21 is fixed with a limiting toothed ring 211. A driving core 212 is slidably arranged in the movable cavity 21. One end of the driving core 212 is provided with a limiting protrusion 2121 that meshes with the limiting toothed ring 211. The other end of the driving core 212 is provided with an external spline 2122. A driving disk 213 is rotatably arranged in the movable cavity 21. The driving core 212 passes through the driving disk 213. A transmission rod 214 is hinged to the driving disk 213. One end of the transmission rod 214 is hinged with a locking rod 215.

[0031] In some embodiments, the locking block 2 has a groove 216 for limiting the horizontal movement of the locking lever 215. The groove 216 can effectively guide and limit the movement trajectory of the locking lever 215, ensuring that the locking lever 215 accurately enters the locking groove 121, thereby improving the reliability and stability of the locking assembly.

[0032] In some embodiments, the active cavity 21 is provided with an ejector spring 217 that brings the drive core 212 closer to the limiting tooth ring 211. The ejector spring 217 is designed to provide a thrust to the drive core 212, so that the limiting protrusion 2121 and the limiting tooth ring 211 remain engaged, thereby limiting the rotation of the drive core 212 and preventing the clamping block 12 from loosening during long-term use.

[0033] In some embodiments, a clamping head 122 is slidably disposed on the inner sidewall of the clamping block 12, and a clamping spring is disposed between the clamping head 122 and the clamping block 12. The clamping head 122 and the clamping spring can improve the clamping force of the wire clamp on the wire and can adapt to wires of different diameters, achieving flexible clamping and avoiding damage to the surface of the wire.

[0034] In some embodiments, a polygonal mounting hole 2123 is provided on one end face of the drive core 212. The design of the polygonal mounting hole 2123 facilitates the insertion of drive tools, such as wrenches, allowing operators to more easily rotate the drive core 212, thereby achieving locking and unlocking operations and improving operational efficiency.

[0035] In some embodiments, the locking lever 215 has a chamfer at one end near the locking groove 121. The chamfer guides the locking lever 215 into the locking groove 121 more smoothly, reducing frictional resistance and improving the smoothness and reliability of the locking operation.

[0036] The working principle of this utility model is as follows:

[0037] Initially, the clamping block 12 can slide freely on the optical axis 112, forming a space between the clamping block 12 and the wire clamp 1 to accommodate the power conductor. The power conductor is then placed between the clamping block 12 and the wire clamp 1. The operator rotates the bolt 111. Because the clamping block 12 is threadedly connected to the bolt 111, and guided by the optical axis 112, rotating the bolt 111 causes the clamping block 12 to move along the optical axis 112, gradually approaching the wire clamp 1. As the clamping block 12 moves, the distance between the clamping block 12 and the wire clamp 1 decreases, generating a clamping force on the power conductor.

[0038] Next, the operator needs to operate the drive disc 213 to achieve locking. The operator presses inward and rotates the drive core 212 using a socket wrench or other tools. Pressing inward disengages the limiting tooth 2121 on the drive core 212 from the limiting tooth ring 211 of the movable cavity 21, allowing it to rotate. The external spline 2122 of the drive core 212 drives the drive disc 213 to rotate, and the rotation of the drive disc 213 is transmitted to the locking lever 215 through the hinged transmission rod 214. The movement of the transmission rod 214 pushes the locking lever 215, causing it to move closer to the clamping block 12. When the locking lever 215 moves to a position aligned with the locking groove 121 on the clamping block 12, the end of the locking lever 215 smoothly slides into the locking groove 121.

[0039] When the pressure on the drive core 212 is stopped, it will move outward under the elastic force of the ejector spring 217, thereby re-engaging the limiting tooth 2121 on the drive core 212 with the limiting tooth ring 211 of the movable cavity 21. This will effectively limit the rotation of the drive core 212, thus achieving locking. At this time, even if the bolt 111 is accidentally loosened, the clamping block 12 will not easily slip, and the power wire will still be reliably clamped.

[0040] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
