Description

Technical Field

[0001] This invention belongs to the field of power line clamp technology, specifically an adjustable power line clamp. Background Technology

[0002] Power line clamps are metal accessories used to connect and combine power systems, transmitting mechanical loads, electrical loads, and providing protection. They can be classified into seven categories according to their function and structure, including suspension clamps, tension clamps, and connecting hardware. They can also be classified into various types according to their material, such as malleable cast iron. Their functions include connecting, fixing, and protecting conductors and conducting current. Commonly used types include C-type clamps, parallel groove clamps, and equipment clamps, which play important roles in scenarios such as power transmission and distribution connections, line splicing and branching, and equipment and conductor connections.

[0003] Current power line clamps still present many inconveniences during use. Due to their relatively simple structure, they cannot adjust the size and angle of the clamping mechanism or the spacing between the two sets of clamping mechanisms. Consequently, they cannot clamp and fix cables of different diameters, angles, and spacings, limiting their applicability. Therefore, those skilled in the art have proposed an adjustable power line clamp to solve the problems mentioned in the background art. Summary of the Invention

[0004] To address the aforementioned technical problems, this invention provides an adjustable power clamp to solve the problem that existing technologies cannot be applied to cables of different diameters, angles, and spacings.

[0005] An adjustable power line clamp includes two sets of lower clamps. A mounting plate is fixedly connected to one side of each set of lower clamps. An upper clamp, rotatably connected to the mounting plate, is provided at the top of each set of lower clamps. Clamping components for fixing cables are provided inside both the upper and lower clamps. A mounting base is provided on the side of the mounting plate away from the lower clamps. A rotating component for adjusting the angle of the lower clamps is provided at the connection between the mounting plate and the mounting base. An upper connecting plate and a lower connecting plate are fixedly connected to the sides of the two mounting bases away from the mounting plate, respectively. An adjusting component for adjusting the distance between the two sets of lower clamps is provided at the connection between the upper and lower connecting plates.

[0006] Preferably, the clamping assembly includes a clamping plate, a first sliding groove, a first connecting groove, a first connecting rod, a first slider, and a first spring. The clamping plate is provided in several sets and is fan-shaped. The first sliding groove is opened inside the upper and lower wire clamps. The first connecting groove passes through the inner wall of the first sliding groove near the center of the upper and lower wire clamps. The first connecting rod is fixedly connected to the outside of the clamping plate and extends through the first connecting groove into the interior of the first sliding groove. The first slider is fixedly connected to the end of the first connecting rod away from the clamping plate and slidably connected to the first sliding groove. The first spring is installed inside the first sliding groove and its two ends are respectively fixedly connected to the inner wall of the first slider away from the clamping plate and the inner wall of the first sliding groove away from the clamping plate.

[0007] Preferably, the rotating assembly includes a second slide groove, a second connecting groove, a second connecting rod, a second slider, and a second spring. The second slide groove is formed inside the mounting base. The second connecting groove passes through the inner wall of the second slide groove near the mounting plate. The second connecting rod is fixedly connected to the center of the mounting plate near the mounting base and extends through the second connecting groove into the second slide groove. The second slider is rotatably connected to the end of the second connecting rod away from the mounting plate and slidably connected to the second slide groove. The second spring is sleeved on the outer periphery of the second connecting rod and its two ends are respectively fixedly connected to the inner wall of the second slider near the mounting plate and the inner wall of the second slide groove near the mounting plate.

[0008] Preferably, the rotating assembly further includes a slot and a block. The slot is formed on the side surface of the mounting base near the mounting plate and is located on the outer periphery of the second connecting groove. The block is fixedly connected to the outer periphery of the end of the second connecting rod away from the second slider and is adapted to the size of the slot.

[0009] Preferably, the adjustment component includes an adjustment groove and an adjustment block. The adjustment groove is convex in shape and is located at the top of the lower connecting plate. The adjustment block is fixedly connected to the bottom of the upper connecting plate and slidably connected to the adjustment groove.

[0010] Preferably, the adjustment assembly further includes fixing holes, through grooves, and fixing rods. The fixing holes are provided in several sets and are opened on the inner wall of the bottom of the adjustment groove. The through grooves pass through the upper connecting plate and the adjustment block. The fixing rods are slidably connected to the through grooves and are adapted to the size of the fixing holes.

[0011] Preferably, the adjusting assembly further includes a third slide groove, a third slider, a third spring, and a pull block. The third slide groove is formed in the inner wall of the through groove. The third slider is fixedly connected to the outer periphery of the fixed rod and slidably connected to the third slide groove. The third spring is sleeved on the outer periphery of the fixed rod and its two ends are respectively fixedly connected to the top of the third slider and the inner wall of the top of the third slide groove. The pull block is fixedly connected to the top of the fixed rod.

[0012] Compared with the prior art, the present invention has the following beneficial effects: 1. This invention, by providing a clamping assembly, pushes the clamping plate away from the center of the upper and lower wire clamps. This causes the first slider to slide along the first groove via the first connecting rod, compressing the first spring. When the clamping plate is released, the first spring rebounds, causing the clamping plate to move closer to the center of the upper and lower wire clamps via the first slider and the first connecting rod. This design allows the wire clamp to clamp and fix wire clamps of different diameters.

[0013] 2. This invention features a rotating assembly. Pulling the mounting plate away from the mounting base causes the second slider to slide along the second groove via the second connecting rod, compressing the second spring. When the locking block moves out of the slot with the mounting plate, the mounting plate can be rotated, adjusting the angles of the upper and lower wire clamps. After rotating to the appropriate angle, releasing the mounting plate causes the second spring to rebound, which in turn moves the mounting plate closer to the mounting base via the second slider and the second connecting rod. When the locking block moves into the slot with the mounting plate, the mounting plate is fixed at the current angle, thus completing the adjustment of the angles of the upper and lower wire clamps. This design allows for adjustment of the angles of both sets of wire clamps, enabling the clamping and fixing of cables at different angles.

[0014] 3. This invention features an adjustment component. Pulling the pull block upwards causes the fixed rod to drive the third slider upwards along the third slide groove, compressing the third spring. When the fixed rod moves out of the fixed hole, it slides along the adjustment groove to adjust the overall length of the upper and lower connecting plates. After adjusting to the appropriate position, releasing the pull block causes the third spring to rebound, which in turn drives the fixed rod downwards via the third slider. When the fixed rod is inserted into the fixed hole, the upper and lower connecting plates are fixed in their current positions. This design allows for adjustment of the spacing between the two sets of wire clamps, enabling the clamping and fixing of cables with different spacings. Attached Figure Description

[0017] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.

[0018] As attached Figure 1 To be continued Figure 6 As shown: Example 1: The present invention provides an adjustable power line clamp, including two sets of lower clamps 1. Each set of lower clamps 1 is fixedly connected to a mounting plate 2 on one side. Each set of lower clamps 1 is provided with an upper clamp 3 rotatably connected to the mounting plate 2 at the top. Both the upper clamp 3 and the lower clamp 1 are provided with clamping components 4 for fixing cables. The clamping components 4 include a clamping plate 41, a first sliding groove 42, a first connecting groove 43, a first connecting rod 44, a first slider 45, and a first spring 46. The mounting plate 2 is provided with a mounting seat 5 on the side away from the lower clamps 1. The two sets of mounting seats 5 are respectively fixedly connected to an upper connecting plate 7 and a lower connecting plate 8 on the side away from the mounting plate 2.

[0019] The clamping plate 41 is provided with several sets in a fan shape. The first sliding groove 42 is opened inside the upper wire clamp 3 and the lower wire clamp 1. The first connecting groove 43 passes through the inner wall of the first sliding groove 42 near the center of the upper wire clamp 3 and the lower wire clamp 1. The first connecting rod 44 is fixedly connected to the outside of the clamping plate 41 and extends through the first connecting groove 43 into the inside of the first sliding groove 42. The first slider 45 is fixedly connected to the end of the first connecting rod 44 away from the clamping plate 41 and is slidably connected to the first sliding groove 42. The first spring 46 is installed inside the first sliding groove 42 and its two ends are fixedly connected to the inner wall of the first slider 45 away from the clamping plate 41 and the inner wall of the first sliding groove 42 away from the clamping plate 41, respectively.

[0020] As can be seen from the above, pushing the clamp plate 41 away from the center of the upper clamp 3 and the lower clamp 1 will cause the first slider 45 to slide along the first groove 42 through the first connecting rod 44 and squeeze the first spring 46. When the clamp plate 41 is released, the first spring 46 rebounds and can drive the clamp plate 41 to move closer to the center of the upper clamp 3 and the lower clamp 1 through the first slider 45 and the first connecting rod 44.

[0021] Example 2: This example is basically the same as the previous example, except that a rotating component 6 for adjusting the angle of the lower clamp 1 is provided at the connection between the mounting plate 2 and the mounting base 5. The rotating component 6 includes a second sliding groove 61, a second connecting groove 62, a second connecting rod 63, a second slider 64, a second spring 65, a slot 66, and a block 67.

[0022] The second slide groove 61 is formed inside the mounting base 5. The second connecting groove 62 passes through the inner wall of the second slide groove 61 near the mounting plate 2. The second connecting rod 63 is fixedly connected to the center of the side of the mounting plate 2 near the mounting base 5 and extends through the second connecting groove 62 into the interior of the second slide groove 61. The second slider 64 is rotatably connected to the end of the second connecting rod 63 away from the mounting plate 2 and slidably connected to the second slide groove 61. The second spring 65 is sleeved on the outer periphery of the second connecting rod 63 and its two ends are fixedly connected to the inner wall of the second slider 64 near the mounting plate 2 and the side of the slide groove 61 near the mounting plate 2, respectively. The slot 66 is formed on the surface of the mounting base 5 near the mounting plate 2 and is located on the outer periphery of the second connecting groove 62. The locking block 67 is fixedly connected to the outer periphery of the end of the second connecting rod 63 away from the second slider 64 and is adapted to the size of the slot 66.

[0023] As can be seen from the above, pulling the mounting plate 2 away from the mounting base 5 will cause the second slider 64 to slide along the second groove 61 via the second connecting rod 63, and compress the second spring 65. When the locking block 67 moves with the mounting plate 2 and moves out of the slot 66, the mounting plate 2 can be rotated, thereby adjusting the angle of the upper wire clamp 3 and the lower wire clamp 1. Releasing the mounting plate 2 will cause the second spring 65 to rebound, which will drive the mounting plate 2 to move closer to the mounting base 5 via the second slider 64 and the second connecting rod 63. When the locking block 67 moves with the mounting plate 2 and is inserted into the slot 66, the mounting plate 2 can be fixed at the current angle, thereby completing the adjustment of the angle of the upper wire clamp 3 and the lower wire clamp 1.

[0024] Example 3: This example is basically the same as the previous example, except that an adjustment component 9 for adjusting the distance between the two sets of lower clamps 1 is provided at the connection between the upper connecting plate 7 and the lower connecting plate 8. The adjustment component 9 includes an adjustment groove 91, an adjustment block 92, a fixing hole 93, a through groove 94, a fixing rod 95, a third sliding groove 96, a third slider 97, a third spring 98, and a pull block 99.

[0025] The adjusting groove 91 is convex in shape and is located on the top of the lower connecting plate 8. The adjusting block 92 is fixedly connected to the bottom of the upper connecting plate 7 and slidably connected to the adjusting groove 91. Several sets of fixing holes 93 are provided and are located on the inner wall of the bottom of the adjusting groove 91. The through groove 94 passes through the upper connecting plate 7 and the adjusting block 92. The fixing rod 95 is slidably connected to the through groove 94 and is adapted to the size of the fixing hole 93. The third sliding groove 96 is located on the inner wall of the through groove 94. The third slider 97 is fixedly connected to the outer periphery of the fixing rod 95 and slidably connected to the third sliding groove 96. The third spring 98 is sleeved on the outer periphery of the fixing rod 95 and its two ends are fixedly connected to the top of the third slider 97 and the inner wall of the top of the third sliding groove 96, respectively. The pull block 99 is fixedly connected to the top of the fixing rod 95.

[0026] As can be seen from the above, pulling the pull block 99 upward will cause the third slider 97 to slide upward along the third slide groove 96 via the fixed rod 95 and compress the third spring 98. When the fixed rod 95 moves out of the fixed hole 93, it can slide along the adjusting groove 91 to adjust the adjusting block 92, thereby adjusting the total length of the upper connecting plate 7 and the lower connecting plate 8. Releasing the pull block 99 will cause the third spring 98 to rebound, which will cause the fixed rod 95 to move downward via the third slider 97. When the fixed rod 95 is inserted into the fixed hole 93, the upper connecting plate 7 and the lower connecting plate 8 can be fixed in the current position.

[0027] Working principle: First, rotate the upper clamp 3 along the mounting plate 2 to open it, place the cable inside the lower clamp 1, then rotate the upper clamp 3 in the opposite direction to reset it, and fix the upper clamp 3 and the lower clamp 1 with bolts. During this process, the cable will drive the clamp plate 41 to move away from the center of the upper clamp 3 and the lower clamp 1. The first connecting rod 44 will drive the first slider 45 to slide along the first slide groove 42 and squeeze the first spring 46. At this time, the rebound force generated by the first spring 46 can clamp and fix the cable in the center of the upper clamp 3 and the lower clamp 1. Open the upper clamp 3 again to take the cable out of the clamp. At this time, the rebound of the first spring 46 can drive the clamp plate 41 through the first slider 45 and the first connecting rod 44 to move closer to the center of the upper clamp 3 and the lower clamp 1 until it is reset, in preparation for subsequent clamping and fixing of the cable.

[0028] When it is necessary to clamp and fix two sets of cables at different angles, pull the mounting plate 2 away from the mounting base 5. This causes the second slider 64 to slide along the second groove 61 via the second connecting rod 63, and compresses the second spring 65. When the locking block 67 moves with the mounting plate 2 and moves out of the slot 66, rotate the mounting plate 2 to make the upper clamp 3 and lower clamp 1 rotate synchronously. After rotating to the appropriate angle, release the mounting plate 2. The second spring 65 rebounds and drives the mounting plate 2 to move closer to the mounting base 5 via the second slider 64 and the second connecting rod 63. When the locking block 67 moves with the mounting plate 2 and is inserted into the slot 66, the mounting plate 2 can be fixed at the current angle, thus completing the adjustment of the angle of the upper clamp 3 and lower clamp 1. At this time, cables at different angles can be clamped and fixed.

[0029] When it is necessary to clamp and fix two sets of cables with different spacings, pull the pull block 99 upward so that it drives the third slider 97 through the fixing rod 95 to slide upward along the third slide groove 96 and compress the third spring 98. When the fixing rod 95 moves out of the fixing hole 93, slide the adjusting block 92 along the adjusting groove 91 so that it drives the upper connecting plate 7 to move synchronously, thereby adjusting the total length of the upper connecting plate 7 and the lower connecting plate 8. When the total length of the upper connecting plate 7 and the lower connecting plate 8 is adapted to the spacing of the cables, release the pull block 99. The third spring 98 rebounds and drives the fixing rod 95 downward through the third slider 97. When the fixing rod 95 is inserted into the fixing hole 93 at the current position, the upper connecting plate 7 and the lower connecting plate 8 can be fixed in the current position, so that the two sets of cable clamps maintain the current spacing. At this time, cables with different spacings can be clamped and fixed.

[0030] The embodiments of the present invention are given for the purposes of illustration and description. Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Any changes, modifications, substitutions and variations made by those skilled in the art to the above embodiments within the scope of the present invention should be included within the protection scope of the present invention.
