Description

Technical Field

[0001] This utility model relates to the field of cable clamp technology, specifically to cable clamps. Background Technology

[0002] Cable clamps are important tools in power construction, mainly used in high-voltage power transmission and transformation projects, line foundation construction, line stringing, pole and tower erection, cable installation, and fiber optic cable installation. Their primary function is to firmly clamp the cable, adjust sag, and tighten it to ensure safe and stable cable operation.

[0003] Chinese Patent No. CN201621407488.0 discloses a cable clamp, including an upper clamp plate, a lower clamp plate, a pressure plate, and a pull plate. One end of the upper clamp plate is rotatably connected to the lower clamp plate, and the other end of the upper clamp plate is rotatably connected to the pressure plate. One end of the pressure plate is rotatably connected to the lower clamp plate, and the other end of the pressure plate is rotatably connected to one end of the pull plate. The other end of the pull plate is slidably connected to the lower clamp plate via a rotating shaft. A cable clamping hole is formed between the upper and lower clamp plates. A pulling assembly is connected to the pull plate to control the other end of the pull plate to slide on the lower clamp plate. The pulling assembly includes a first pulling part and a second pulling part.

[0004] When using this utility model, it is impossible to limit the range of motion of the cable. When the tension deviates, the cable is prone to detachment. At the same time, during the clamping process, it is very inconvenient to manually maintain the pulling and clamping state in the initial stage. Utility Model Content

[0005] Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this utility model provides a cable clamp that solves the problems of not being able to limit the range of cable movement, the tendency for the cable to come off when the tension deviates, and the need for manual pulling and clamping during the initial stage of clamping.

[0007] Technical solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: a cable clamp, comprising a clamp; the clamp consists of a lower clamp plate, an upper clamp plate, and a pull plate, the upper clamp plate being located above the lower clamp plate, the pull plate being located above the upper clamp plate, connecting rods being rotatably mounted on both ends of one side of the lower clamp plate, the upper clamp plate, and the pull plate, a reset mechanism being installed inside the shaft of the upper side of the connecting rod located inside the pull plate, the reset mechanism being installed on the upper side of the pull plate, limit mechanisms being installed on both sides of the lower clamp plate, and a pull ring being rotatably mounted on the front end of the pull plate.

[0009] Preferably, the reset mechanism consists of a spring box and a mounting plate, wherein the mounting plate is installed on both sides of the spring box and on the upper side of the pull plate.

[0010] Preferably, the bottom end of the upper clamping plate and the top end of the lower clamping plate are both provided with V-shaped grooves.

[0011] Preferably, the V-groove has serrations inside.

[0012] Preferably, the limiting mechanism consists of a fixed ring and a rotating ring, with the fixed ring installed at both ends of the lower clamping plate and the rotating ring rotatably installed on the outside of the fixed ring.

[0014] Preferably, wrenches are provided at both the upper and lower ends of the rotating ring, and the wrenches are welded to both sides of the rotating ring.

[0015] Beneficial effects

[0016] Compared with the prior art, the present invention provides a cable clamp with the following advantages:

[0017] 1. When clamping the cable, the cable is restricted by the limiting mechanism, making it difficult for the cable to fall out of the position between the upper and lower clamps. At the same time, the reset mechanism will drive the connecting rod to rotate, which in turn drives the upper and lower clamps to rotate, automatically clamping and fixing the cable.

[0018] 2. When in use, the reset mechanism rotates between the pull plate and the connecting rod via the spring box, thereby enabling the wire clamp to automatically hold the wire.

[0019] 3. When using the limiting mechanism, the wire is inserted into the fixed ring through the fixed ring and the rotating ring and the opening. Then, by rotating the rotating ring, the opening of the fixed ring can be closed. Attached Figure Description

[0026] In this utility model, unless otherwise stated, the orientations used, such as "up" and "down", usually refer to the direction shown in the accompanying drawings, or to the vertical, perpendicular, or gravitational direction; similarly, for ease of understanding and description, "left" and "right" usually refer to the left and right shown in the accompanying drawings; "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not used to limit this utility model.

[0027] This utility model provides a technical solution:

[0028] Please see Figures 1-4 The cable clamp includes a clamp 1; the clamp 1 consists of a lower clamp 6, an upper clamp 4 and a pull plate 2. The upper clamp 4 is located above the lower clamp 6, and the pull plate 2 is located above the upper clamp 4. A connecting rod 3 is rotatably installed at both ends of one side of the lower clamp 6, the upper clamp 4 and the pull plate 2. A reset mechanism 10 is installed inside the shaft of the upper side of the connecting rod 3 inside the pull plate 2. The reset mechanism 10 is installed on the upper side of the pull plate 2. Limiting mechanisms 9 are located on both sides of the lower clamp 6. A pull ring 7 is rotatably installed at the front end of the pull plate 2.

[0029] Furthermore, the reset mechanism 10 consists of a spring box 11 and a mounting plate 12. The mounting plate 12 is installed on both sides of the spring box 11 and on the upper side of the pull plate 2. When in use, the reset mechanism 10 drives the pull plate 2 and the connecting rod 3 to rotate through the spring box 11, thereby enabling the wire clamp 1 to automatically clamp the wire.

[0030] Furthermore, V-grooves 5 are provided at the bottom of the upper clamping plate 4 and the top of the lower clamping plate 6. The V-grooves 5 are provided to increase the contact area between the upper clamping plate 4 and the lower clamping plate 6 and the cable.

[0031] Furthermore, the V-groove 5 is provided with serrations 8 inside. The serrations 8 are provided to increase the friction inside the V-groove 5 and prevent slippage between the upper clamping plate 4 and the lower clamping plate 6 and the cable during use.

[0032] Furthermore, the limiting mechanism 9 consists of a fixed ring 16 and a rotating ring 14. The fixed ring 16 is installed at both ends of the lower clamping plate 6, and the rotating ring 14 is rotatably installed on the outside of the fixed ring 16. When the limiting mechanism 9 is in use, the wire is inserted into the fixed ring 16 through the fixed ring 16 and the rotating ring 14 and the opening. By rotating the rotating ring 14, the opening of the fixed ring 16 can be closed.

[0033] Furthermore, limit rings 15 are provided on both sides of the fixed ring 16. The limit rings 15 are integrally formed with the fixed ring 16. The limit rings 15 are used to limit the range of motion of the rotating ring 14 and prevent the rotating ring 14 from detaching from the fixed ring 16 during use.

[0034] Furthermore, wrenches 13 are provided at both the upper and lower ends of the rotating ring 14. The wrenches 13 are welded to both sides of the rotating ring 14. The wrenches 13 are provided for workers to hold, thereby facilitating the rotation of the rotating ring 14.

[0035] In practical use, the working principle of this utility model is as follows: When the cable clamp 1 is in use, the upper clamp 4 and the lower clamp 6 clamp the cable. When clamping the cable, the cable is restricted by the limiting mechanism 9, making it difficult for the cable to fall out of the position between the upper clamp 4 and the lower clamp 6. At the same time, the reset mechanism 10 will drive the connecting rod 3 to rotate. The connecting rod 3 drives the upper clamp 4 and the lower clamp 6 to rotate, automatically clamping and fixing the cable. After clamping is completed, under the drive of the traction mechanism, the pull plate 2 drives the connecting rod 3 to rotate. The connecting rod 3 drives the upper clamp 4 and the lower clamp 6 to clamp and pull the cable tightly.

[0036] The above are merely specific embodiments of this utility model, but the technical features of this utility model are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on this utility model to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of this utility model.
