Description

Technical Field

[0001] This utility model relates to the field of cable fastener technology, specifically a cable anti-loosening fastening structure. Background Technology

[0002] In traditional power transmission systems, the composite optical cable ground wire down-lead optical cable is prone to detaching from the rubber clamp of the fixing device, which can cause unplanned tripping of the transmission line and affect the stability of power transmission.

[0003] After a thorough preliminary investigation and analysis, it was found that traditional fixing devices generally undergo irreversible aging after prolonged use, such as cracking, deformation, and breakage. Their fastening performance gradually fails to meet the needs of practical applications. When this happens to high-voltage optical cables, it can also release voltage to the surrounding environment, exacerbating unreliability. The root cause of this problem can be traced back to its design flaws; the design did not consider the aging process over long-term use, thus posing a safety hazard. Utility Model Content

[0004] To address the technical problems existing in the background art, this utility model provides a cable anti-detachment fastening structure.

[0005] The technical solution of this utility model is as follows:

[0006] A cable anti-detachment fastening structure is detachably connected to a utility pole, including a buckle assembly, a connecting assembly, and an anti-detachment assembly, wherein the buckle assembly is connected to the anti-detachment assembly through the connecting assembly.

[0007] The buckle assembly includes an arc-shaped steel band clamp and an adjustment assembly. The adjustment assembly connects to both ends of the steel band clamp and can adjust the distance between the two ends.

[0008] The anti-detachment component includes a U-shaped anti-detachment fastener with an opening facing or away from the snap-fit ​​component. It has a rubber clamp installed inside, a galvanized pressure plate inserted into the opening, and is prevented from falling off by a limiting component.

[0009] The connecting assembly includes a second bolt, one end of which is connected to the adjusting assembly, and the other end of which penetrates vertically through the anti-detachment assembly and is fitted with tightening nuts on the outside of the anti-detachment fastener and the galvanized pressure plate, respectively. The second bolt, the adjusting assembly, and the steel band clamp are coplanar.

[0010] The anti-loosening fastener is easy to process and has a double guarantee of fixing the galvanized pressure plate with tightening nuts and limiters.

[0011] The adjustment assembly includes a first aluminum block and a second aluminum block set at both ends of the steel belt clamp, and a first bolt passing through the two aluminum blocks. A nut is set on the outside of the first aluminum block to cooperate with the first bolt.

[0012] The first bolt and nut are used to adjust the distance between the first and second aluminum blocks, and the radius of the steel band clamp is adjusted to connect to the utility pole.

[0013] The second bolt connects to the second aluminum block and is perpendicular to the first bolt.

[0014] The second bolt is secured to the second aluminum block by tightening the nut.

[0015] Preferably, the first aluminum block and the second aluminum block are identical in shape and interchangeable, providing another option for the second bolt connection position. In the event of cracking of the first aluminum block, the second aluminum block is connected to the second bolt as a replacement part.

[0016] As a further preferred option, the side length of the second aluminum block is greater than the sum of the diameters of the first and second bolts, thus ensuring that the two bolts have sufficient space to connect.

[0017] The galvanized pressure plate has symmetrical holes at both ends along the centerline for inserting anti-loosening fasteners.

[0018] The second bolt is inserted vertically into the anti-detachment component from the center of the galvanized pressure plate.

[0019] The anti-loosening fastener has through holes on both sides of the open end to insert a limiting component, which is a cotter pin.

[0020] Furthermore, the cotter pin is a type B cotter pin, which can be detachably connected to the anti-loosening fastener.

[0021] The rubber clamp includes two interlocking connecting blocks with their mating surfaces perpendicular to the axis of the second bolt.

[0022] In addition, the outer edge of the rubber clamp is in close contact with the anti-loosening fastener and the galvanized pressure plate. Each connecting block is square and has the same shape. The second bolt passes through the middle of the rubber clamp.

[0023] The connecting block mating surface has two sets of mating grooves, and the axis of the mating grooves is parallel to the axis of the steel belt clamp.

[0024] The beneficial effects of this utility model are:

[0030] To facilitate understanding of this utility model, a more comprehensive description of this utility model will be given below with reference to the accompanying drawings.

[0031] Example 1

[0032] Reference Figure 1 A cable anti-detachment fastening structure is detachably connected to a utility pole, including a buckle assembly, a connecting assembly, and an anti-detachment assembly, wherein the buckle assembly is connected to the anti-detachment assembly through the connecting assembly.

[0033] The buckle assembly includes an arc-shaped steel band clamp 1 and an adjustment component 2. The adjustment component 2 connects to both ends of the steel band clamp 1 and can adjust the distance between the two ends.

[0034] The anti-detachment component includes a U-shaped anti-detachment fastener 3 with an opening facing or away from the buckle component, a rubber clamp 4 installed inside, a galvanized pressure plate 5 inserted into the opening, and a limiting member 6 to prevent it from falling off.

[0035] The connecting assembly includes a second bolt 7. One end of the second bolt 7 is connected to the adjusting assembly 2, and the other end penetrates vertically through the anti-detachment assembly and is fitted with tightening nuts on the outside of the anti-detachment fastener 3 and the galvanized pressure plate 5, respectively. The second bolt 7, the adjusting assembly 2, and the steel band clamp 1 are coplanar.

[0036] The anti-loosening fastener 3 is easy to process, and has a double guarantee of fixing the galvanized pressure plate 5 with a tightening nut and a limiting part 6. In addition, the thickness of the anti-loosening fastener 3 is greater than the thickness of the rubber clamp 4, which can increase the contact area and firmly fix the rubber clamp 4.

[0037] The adjusting component 2 includes a first aluminum block 201 and a second aluminum block 202 disposed at both ends of the steel band clamp 1, and also includes a first bolt 203 passing through the two aluminum blocks. A nut is disposed on the outside of the first aluminum block 201 to cooperate with the first bolt 203.

[0038] The first bolt 203 and nut are used to adjust the distance between the first aluminum block 201 and the second aluminum block 202, and the radius of the steel band clamp 1 is adjusted to connect to the utility pole.

[0039] The second bolt 7 is connected to the second aluminum block 202 and is perpendicular to the first bolt 203.

[0040] The second bolt 7 is fixed to the second aluminum block 202 by tightening the nut.

[0041] Preferably, the first aluminum block 201 and the second aluminum block 202 are identical in shape and interchangeable, providing another option for the connection position of the second bolt 7. When the first aluminum block 201 cracks, the second aluminum block 202 is connected to the second bolt 7 as a replacement part.

[0042] As a further preferred option, the side length of the second aluminum block 202 is greater than the sum of the diameters of the first bolt 203 and the second bolt 7. This ensures that the two bolts have enough space to connect, and the connected structure is stable. After testing, it was found that the overall structure can indeed maintain its balance.

[0043] The galvanized pressure plate 5 has symmetrical holes at both ends about the centerline to insert anti-loosening fasteners 3, which are evenly stressed and have a stable fit.

[0044] The second bolt 7 is inserted vertically into the anti-detachment component from the center of the galvanized pressure plate 5, ensuring stable force distribution and a simpler structure, thus reducing costs.

[0045] The anti-loosening fastener 3 has through holes on both sides of the open end to insert the limiting member 6, which is a cotter pin.

[0046] Furthermore, a type B cotter pin is selected, which can be detachably connected to the anti-loosening fastener 3.

[0047] Within the same plane, the three sides of the anti-loosening fastener 3 are perpendicular in sequence. It has high strength during use and low manufacturing cost.

[0048] The rubber clamp 4 includes two interlocking connecting blocks with their mating surfaces perpendicular to the axis of the second bolt 7.

[0049] In addition, the outer edge of the rubber clamp 4 is in close contact with the anti-loosening fastener 3 and the galvanized pressure plate 5. Each connecting block is square and has the same shape. The second bolt 7 passes through the middle of the rubber clamp 4. This connection method ensures that the galvanized pressure plate 5, the rubber clamp 4 and the anti-loosening fastener 3 are on the second bolt 7, and the force is stable and there will be no relative displacement.

[0050] This design effectively resists the aging and cracking of rubber caused by natural environmental factors such as weathering, thereby ensuring the long-term stability of the cable position, avoiding the risk of cable displacement due to damage to the clamp, and greatly improving the overall safety performance and durability.

[0051] The connecting block has two sets of joint grooves on its mating surface, with the axis of the joint grooves parallel to the axis of the steel strap clamp 1. During installation, first, the steel strap clamp 1 is wrapped around the utility pole and adjusted to a suitable position. Then, the distance between the first aluminum block 201 and the second aluminum block 202 is adjusted using the first bolt 203 to ensure the steel strap clamp 1 fits tightly against the utility pole. Next, the second bolt 7 is installed, and a tightening nut is attached to it. A galvanized pressure plate 5 and a connecting block are then inserted, and the cable is fixed in the groove of the connecting block. Another connecting block is inserted onto the second bolt 7 to clamp the cable. Anti-detachment fasteners 3 are fitted over the rubber clamp 4, cooperating with the galvanized pressure plate 5 during installation. After installation, the limiting piece 6 is inserted, and the outermost tightening nut is tightened to complete the installation of the entire structure.
