Technical Field
[0001] This utility model relates to the technical field of power engineering, specifically a wire clamp device. Background Technology
[0002] Power line clamps are one of the clamps used in power engineering to fix and protect high-voltage cables. In order to prevent cable slippage and ensure the normal operation of the cable, they are made of high-strength corrosion-resistant aluminum alloy, which can withstand large tensile and compressive forces and is suitable for various harsh environments, and is therefore widely used.
[0003] Existing power line clamps are often designed to fit different specifications of cables, making it difficult to use different specifications of cables on the same clamp, resulting in poor applicability. Furthermore, most clamps are fixed with simple bolts and nuts, and the vibration of the cable when blown by the wind can easily cause the nuts to loosen, affecting the clamp's fixing effect. Therefore, we propose a clamp device to solve the problems mentioned above. Utility Model Content

In addition, wire clamps are mostly fixed with simple bolts and nuts, and the vibration of the cable when it is blown by the wind can easily cause the nut to loosen, affecting the fixing effect of the wire clamp.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a wire clamp device, comprising an upper clamp plate, a lower clamp plate, a mounting screw, and a fastening nut. The lower clamp plate is located below the upper clamp plate. A groove is formed in the center of the surface of the lower clamp plate.

Mounting screws are threaded through both ends of the upper and lower clamp plates, and fastening nuts are threaded to both ends of the mounting screws. A spring and a limiting ring are provided above the upper clamp plate on the mounting screw.

[0008] Preferably, the adjusting screw is connected to the middle of the upper clamping plate by a threaded connection, and the lower part of the adjusting screw is rotatably connected to the inner clamping plate.

[0010] Preferably, the inner clamping plate is arranged in a semi-circular arc shape, and the width of the inner clamping plate is equal to the width of the groove on the surface of the lower clamping plate. The second protective pad and the first protective pad on the lower surface of the inner clamping plate are both made of elastic rubber.
[0011] By adopting the above technical solution, when the inner plate moves downward, the second protective pad on its inner side can work in conjunction with the first protective pad to clamp and fix the cable at its inner end.
[0012] Preferably, the magnetic clip and the groove on the upper surface of the lower clamping plate are engaged in a one-to-one correspondence, and the upper clamping plate is magnetically connected to the lower clamping plate through the magnetic clip.
[0013] By adopting the above technical solution, the magnetic connection between the upper clamping plate and the groove of the lower clamping plate can be achieved through the magnetic locking block under the upper clamping plate.
[0014] Preferably, the positioning screw and the magnetic block are configured in a one-to-one correspondence, and the side of the lower clamping plate is connected to the threaded insertion hole in the middle of the magnetic block below the upper clamping plate through the positioning screw.
[0015] By adopting the above technical solution, the positioning screw on the side of the lower clamping plate can be connected to the threaded hole on the surface of the magnetic clamping block, which facilitates a stable connection between the upper clamping plate and the lower clamping plate.
[0016] Compared with the prior art, the beneficial effects of this utility model are: this wire clamp device,
[0017] The inner clamping plate, which engages with the slotted surface of the lower clamping plate by adjusting the screw, facilitates the compression and clamping of cables of different sizes, thereby improving the effectiveness of the device.
[0018] The upper and lower clamps can be engaged by the magnetic locking block below the upper clamp and the groove above the lower clamp, and with the use of the positioning screw, the upper and lower clamps can be fixed for a second time, reducing the possibility of the upper and lower clamps becoming loose after the fastening nut loosens.

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.
[0025] Please see Figure 1-4This utility model provides a technical solution: a wire clamp device, including an upper clamping plate 1, a lower clamping plate 2, a mounting screw 5, and a fastening nut 6. The lower clamping plate 2 is located below the upper clamping plate 1. A groove 4 is formed in the middle of the surface of the lower clamping plate 2. First protective pads 3 are bonded to both sides of the groove 4 on the surface of the lower clamping plate 2. The mounting screw 5 is connected through both ends of the upper clamping plate 1 and the lower clamping plate 2, and the upper and lower ends of the mounting screw 5 are threaded with fastening nuts 6. A spring 7 and a limiting ring 8 are provided above the upper clamping plate 1 on the mounting screw 5. Two sets of limiting rings 8 are provided, located at both ends of the spring 7. The outer diameter of the limiting ring 8 is smaller than the outer diameter of the fastening nut 6, which facilitates the use of the spring 7 above the upper clamping plate 1. When fixed, the spring 7 expands by compression, raising the upper clamping plate 1 and the lower clamping plate. The connection of 2 is firm. An adjusting screw 9 is installed in the middle of the upper part of the upper clamping plate 1, and an inner clamping plate 10 is provided below the adjusting screw 9. The adjusting screw 9 is connected to the middle of the upper clamping plate 1 by a threaded connection, and the lower part of the adjusting screw 9 is rotatably connected to the inner clamping plate 10. By rotating the adjusting screw 9, the adjusting screw 9 can drive the lower inner clamping plate 10 to move downward. A second protective pad 11 is bonded to the surface of the inner clamping plate 10. The inner clamping plate 10 is set in a semi-circular arc shape, and the width of the inner clamping plate 10 is equal to the width of the groove 4 on the surface of the lower clamping plate 2. The second protective pad 11 and the first protective pad 3 on the lower surface of the inner clamping plate 10 are both made of elastic rubber. When the inner clamping plate 10 moves downward, the second protective pad 11 on its inner side can cooperate with the first protective pad 3 to clamp and fix the cable at its inner end.
[0026] Please see Figure 1-4 The upper clamping plate 1 has four fixed magnetic blocks 12 at its lower corners, and each magnetic block 12 has a threaded insertion hole 14 in the center of its surface. The magnetic blocks 12 and the grooves 13 on the upper surface of the lower clamping plate 2 are locked in a one-to-one manner. The upper clamping plate 1 and the lower clamping plate 2 are magnetically connected through the magnetic blocks 12. The magnetic blocks 12 on the lower surface of the upper clamping plate 1 are magnetically connected to the grooves 13 on the lower clamping plate 2, so that the upper clamping plate 1 and the lower clamping plate 2 can be locked in a one-to-one manner. The lower clamping plate 2 has grooves 13 in the four corners of its upper surface. The lower clamping plate 2 has a positioning screw 15 installed on its side. The positioning screw 15 and the magnetic blocks 12 are locked in a one-to-one manner. The lower clamping plate 2 is connected to the threaded insertion hole 14 in the center of the magnetic blocks 12 on the lower surface of the upper clamping plate 1 through the positioning screw 15. The positioning screw 15 on the side of the lower clamping plate 2 is connected to the threaded insertion hole 14 on the surface of the magnetic blocks 12, so that the upper clamping plate 1 and the lower clamping plate 2 can be locked in a one-to-one manner through the threaded insertion hole 14 on the surface of the magnetic blocks 12.
[0027] Working principle: First, when in use, the cable is placed on the lower clamping plate 2, and the upper clamping plate 1 and the lower clamping plate 2 are initially fixed by using the installation screw 5 and the fastening nut 6. A spring 7 is provided between the upper clamping plate 1 and the fastening nut 6. The elasticity of the spring 7 can improve the firmness of the upper clamping plate 1 and the lower clamping plate 2. Then, by rotating the adjusting screw 9, the adjusting screw 9 moves downward, which causes the inner clamping plate 10 below the adjusting screw 9 to move downward on the slot 4 on the surface of the lower clamping plate 2. This allows the second protective pad 11 on the inner surface of the inner clamping plate 10 to squeeze and clamp the cable below.
[0028] The four lower corners of the upper clamping plate 1 are engaged with the grooves 13 on the upper surface of the lower clamping plate 2 by magnetic clips 12, which facilitates the installation of the upper clamping plate 1 and the lower clamping plate 2. At the same time, with the use of the positioning screws 15 on the side of the lower clamping plate 2, the positioning screws 15 can be threaded into the threaded holes 14 on the surface of the magnetic clips 12, so as to ensure a stable connection between the upper clamping plate 1 and the lower clamping plate 2 and improve the use effect of the device. This is the working principle of the wire clamp device.
[0029] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
