Description

Technical Field

[0001] This utility model relates to the field of power fittings technology, and in particular to aluminum alloy cable fixing clamps. Background Technology

[0002] Power fittings, also known as power accessories or power hardware, refer to various accessories and components used in power systems to support, connect, and fix power equipment and cables. They play an important role in power transmission and distribution systems, ensuring the stability, safety, and reliability of the power system. Among them, aluminum alloy cable clamps are a type of power fitting. They are devices made of aluminum alloy used to fix cables to a supporting structure.

[0003] Currently, common cable clamps can be divided into single-core cable clamps and multi-core cable clamps based on the number of cables they fix. Single-core cable clamps are devices used to fix and support single-core cables. However, in common single-core cable clamp structures, when installing and fixing cables, the upper and lower parts of the clamp are usually engaged with the outer circumference of the cable, and then bolts and nuts are installed to fix the clamp. However, in order to prevent the cable from coming out of the clamp, the operator usually needs to hold the clamp by hand to limit its movement before the bolts and nuts can be installed, which makes the installation inconvenient and the actual use effect is poor. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an aluminum alloy cable fixing clamp, which aims to improve the inconvenience for workers when installing threaded parts in the prior art.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: an aluminum alloy cable fixing clamp, including a housing one, a housing two disposed on a lower side of the housing, a fixing block fixedly connected to one side wall of the housing, an mounting block fixedly connected to the side wall of the housing two, a guide rod penetrating through the top wall of the fixing block, a protrusion fixedly connected to the bottom end of the guide rod penetrating through the bottom wall of the mounting block, a rotating shaft rotatably connected to the inner walls of the front and rear sides of the protrusion, a locking block fixedly connected to the middle of each of the two rotating shafts, and both locking blocks engaging with the bottom wall of the mounting block, a connecting plate fixedly connected to the middle of the guide rod, a spring one fixedly connected to the top wall of the connecting plate, and the top end of the spring one fixedly connected to the inner top wall of the fixing block.

[0006] The above technical solution avoids the need for workers to manually hold the wire clamp for limiting the position when installing threaded parts, thus improving the convenience of installation.

[0007] As a further description of the above technical solution:

[0008] Both housing one and housing two have through grooves on their adjacent sides. Both housing one and housing two have threaded rods rotatably connected to their opposite sides at the middle. The adjacent ends of the two threaded rods penetrate the inner wall of the through groove and are threadedly connected to clamping plates. Both clamping plates are slidably connected to the inner wall of the through groove. Both sides of the adjacent walls of the two clamping plates have grooves. Multiple clamping blocks are slidably connected in multiple grooves. One end of the two clamping blocks on opposite sides is fixedly connected to the opposite side. The other end of the multiple two springs is fixedly connected to the inner wall of the groove.

[0009] The above technical solution enables the fixing and centering of cables of different specifications.

[0010] As a further description of the above technical solution:

[0011] Each of the two clamping plates has a limiting groove in the middle of its adjacent side. Each of the two threaded rods has a limiting plate fixedly connected to its adjacent end. Both limiting plates are slidably connected in the limiting groove. Each of the two clamping plates has a limiting rod passing through its middle sides. The upper and lower limiting rods are fixedly connected to the inner walls of housing one and housing two, respectively, at their opposite ends.

[0012] The above technical solution can prevent the clamping plate from rotating and ensure the stability of the clamping plate's movement.

[0013] As a further description of the above technical solution:

[0014] Each of the multiple clamping blocks has a positioning rod penetrating through its middle, and both ends of the multiple positioning rods are fixedly connected to the two side walls inside the groove. The multiple springs are all arranged on the outer periphery of the positioning rods.

[0015] The above technical solution can ensure the stability of the clamping block movement and prevent the spring from bending after being compressed.

[0016] As a further description of the above technical solution:

[0017] Both sides of the top wall of the housing are provided with arc grooves. The bottom ends of the two arc grooves pass through the bottom wall of the housing, the top wall of the housing, and the bottom wall of the housing in sequence. Bolts pass through the arc grooves on both sides, and nuts are threaded to the top of the two bolts.

[0018] The above technical solution can adapt to cable placement errors and avoid the hazards of cable serpentine swinging.

[0019] As a further description of the above technical solution:

[0020] Both of the two rotating shafts are provided with torsion springs on the outer periphery of their front and rear ends. One end of each torsion spring is fixedly connected to the locking block, and the other end of each torsion spring is fixedly connected to the inner wall of the protrusion.

[0021] The above technical solution allows the locking block to reset itself under the action of the torsion spring, improving ease of use.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0031] Reference Figures 1-3An embodiment of this utility model provides an aluminum alloy cable fixing clamp, including a housing 1. A fixing block 13 is fixedly connected to the side wall of the housing 1. An mounting block 14 is fixedly connected to the side wall of the housing 2. A guide rod 18 passes through the top wall of the fixing block 13. The bottom end of the guide rod 18 passes through the bottom wall of the mounting block 14 and is fixedly connected to a protrusion 15. A rotating shaft 23 is rotatably connected to the inner walls of the front and rear sides of the protrusion 15. A locking block 16 is fixedly connected to the middle of each of the two rotating shafts 23. The two locking blocks 16 are locked into the bottom wall of the mounting block 14. A connecting plate 17 is fixedly connected to the middle of the guide rod 18. A spring 19 is fixedly connected to the top wall of the connecting plate 17. The top end of the spring 19 is fixedly connected to the inner top wall of the fixing block 13. Torsion springs 24 are provided on the outer periphery of the front and rear ends of the two rotating shafts 23. One end of each torsion spring 24 is fixedly connected to the locking block 16, and the other end of each torsion spring 24 is fixedly connected to the inner wall of the protrusion 15.

[0032] Specifically, during cable clamp installation, the operator can initially engage the cable by pressing the housing 1 and housing 2. At this time, the operator can press the guide rod 18 to move the protrusion 15 downwards. As the protrusion 15 moves, it also moves the connecting blocks 16 on the front and rear sides downwards, allowing both the protrusion 15 and the blocks 16 to pass through the bottom wall of the mounting block 14. When the blocks 16 pass through the bottom wall of the mounting block 14, they are squeezed, causing the blocks 16 to rotate inwards and pull the torsion spring 24. After the blocks 16 pass through the bottom wall of the mounting block 14, they lose their limit and, under the action of the torsion spring 24, are pulled outwards and reset. Since the guide rod 18 also moves the connecting plate 17 downwards and pulls the spring 19, the clamp... After resetting, block 16 can release guide rod 18 and, under the action of spring 19, move guide rod 18 upward and cause locking block 16 to move upward and engage with the bottom wall of mounting block 14, thus initially limiting the wire clamp. When it is necessary to cancel the limit, simply press guide rod 18 again and push locking block 16 to rotate inward. Then, under the action of spring 19, pull guide rod 18 to reset and drive locking block 16 and protrusion 15 to retract into fixing block 13, thereby canceling the limit between fixing block 13 and mounting block 14. This achieves the goal of initially limiting the wire clamp before fixing housing 1 and housing 2, and canceling the limit after fixing. This avoids the need for workers to manually hold the wire clamp for limiting when installing threaded parts, improving the convenience of installation.

[0033] Reference Figures 1-3A second housing 2 is provided on the lower side of the first housing 1. Both the first housing 1 and the second housing 2 have through grooves 4 on their adjacent sides. Both the first housing 1 and the second housing 2 have threaded rods rotatably connected to the middle of their opposite sides. The adjacent ends of the two threaded rods 3 pass through the inner wall of the through groove 4 and are threadedly connected to clamping plates 5. Both clamping plates 5 are slidably connected to the inner wall of the through groove 4. Both sides of the clamping plates 5 have grooves 6 on their adjacent sides. Clamping blocks 7 are slidably connected in multiple grooves 6. One end of spring 21 is fixedly connected to the opposite side of the clamping blocks 7 on both sides. The other end of multiple spring 21 is fixedly connected to the inner wall of the groove 6. Positioning rods 20 pass through the middle of multiple clamping blocks 7. Both ends of multiple positioning rods 20 are fixedly connected to the inner side walls of the groove 6. Multiple spring 21 are provided on the outer periphery of the positioning rods 20.

[0034] Specifically, when the cable is between housing 1 and housing 2, rotating the threaded rod 3 can drive the outer connecting clamp 5 to move. Since the clamp 5 is limited and cannot rotate, the rotation of the threaded rod 3 can drive the connecting clamp 5 to move up and down along the threaded rod 3. When the clamp 5 moves towards the cable, the clamp 5 will contact the cable and press the cable. At the same time, when the clamp 5 contacts the cable, the cable will also contact the clamp 7 and squeeze the clamp 7. Thus, the cable will push the clamp 7 on both sides to move away from each other. Furthermore, when the clamping block 7 moves, it will also compress the second spring 21. When the second spring 21 is compressed, it will also provide a reverse force. Under the action of the second spring 21, the clamping block 7 will be pushed to clamp and fix the cable and push the cable to the middle position of the clamp to achieve the centering effect. At the same time, under the action of the positioning rod 20, the positioning rod 20 will limit the clamping block 7 and the second spring 21, thereby ensuring the stability of the movement of the clamping block 7 and preventing the second spring 21 from bending after being compressed. This achieves the effect of fixing and centering cables of different specifications.

[0035] Reference Figures 1-3 Both clamping plates 5 have a limiting groove 22 in the middle of their adjacent sides. Both threaded rods 3 are fixedly connected to a limiting plate 9 at their adjacent ends. Both limiting plates 9 are slidably connected in the limiting groove 22. Both clamping plates 5 have a limiting rod 8 passing through their middle sides. The upper and lower limiting rods 8 are fixedly connected to the inner walls of housing 1 and housing 2 respectively at their far ends.

[0036] Specifically, since the limiting plate 9 slides within the limiting groove 22, it can limit the threaded rod 3 and the clamping plate 5 under the action of the limiting plate 9, thereby preventing the clamping plate 5 from completely falling off the threaded rod 3, so as to ensure the stability of the connection and movement of the clamping plate 5. By setting the limiting rod 8, the clamping plate 5 can be limited, thereby preventing the clamping plate 5 from rotating and ensuring the stability of the movement of the clamping plate 5.

[0037] Reference Figures 1-3Both sides of the top wall of shell 1 are provided with arc grooves 10. The bottom ends of the two arc grooves 10 pass through the bottom wall of shell 1, the top wall of shell 2, and the bottom wall of shell 2 in sequence. Bolts 11 pass through the arc grooves 10 on both sides, and nuts 12 are threaded to the top of the two bolts 11.

[0038] Specifically, by setting the arc groove 10, the bolt 11 can pass through the housing 2 and the housing 1 in sequence. Then, by tightening the bolt 11, the housing 1 and the housing 2 are fixed and limited. The bolt 11 can also move within the arc groove 10, thereby adapting to the cable placement error and avoiding the harm of the cable serpentine swing.

[0039] Working Principle: In actual use, when installing the cable clamp, the operator can initially engage the cable by pressing the guide rod 18 and the locking block 15 through the top wall of the mounting block 14. This causes the two locking blocks 16 to rotate outwards and engage with the bottom wall of the mounting block 14, thus initially limiting the cable clamp. When it is necessary to cancel the limiting, simply press the guide rod 18 again to reset the locking blocks 16. Under the action of the spring 19, the locking blocks 16 and the protrusion 15 reset and retract into the fixing block 13, thus achieving initial limiting of the cable clamp and preventing the operator from accidentally engaging the cable clamp during subsequent installation. When using threaded parts, it is necessary to limit the manual grip of the wire clamp to improve the convenience of installation. In addition, when the cable is between housing 1 and housing 2, rotating the threaded rod 3 can drive the clamp 5 to move towards the cable. When the clamp 5 contacts the cable, it will press the cable. At the same time, when the clamp 5 contacts the cable, the cable will also squeeze the clamp block 7, which will push the clamp blocks 7 on both sides to move away from each other and compress the spring 21. Under the action of the spring 21, the clamp block 7 will also push the cable to clamp and fix it, and can also push the cable to the middle position of the wire clamp to achieve the centering effect. This achieves the effect of fixing and centering cables of different specifications.

Although the present utility model 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.
