Abstract
Description
Technical Field
[0001] This utility model relates to the field of auxiliary tools for power distribution equipment, and in particular to a wire fixing device. Background Technology
[0002] Overhead power distribution lines are crucial for power transmission. These lines are typically insulated from the ground by insulators. Securely and conveniently fixing overhead conductors to these insulators has always been a key concern in distribution network construction and maintenance. The traditional method involves using PVC-coated copper wire with a "three-front, four-back double cross" binding method to secure the conductors to porcelain insulators. While this method is convenient due to the numerous binding points, its quality heavily relies on the diligence of the construction workers, and managing material sourcing is challenging. Some construction companies even use PVC-coated aluminum wire or bare aluminum wire for binding, significantly compromising quality and leading to issues like loose bindings, conductor slippage, and ultimately, short circuits or grounding faults. Therefore, there is an urgent need to design a convenient and efficient overhead conductor securing device. Utility Model Content
[0003] In view of this, the main purpose of this utility model is to propose a conductor fixing device, which aims to solve the problem of how to fix overhead conductors securely and conveniently to insulators.
[0004] To achieve the above objectives, this utility model provides a wire fixing device, which includes a locked state and a released state. The wire fixing device includes a clamp, a pressure plate, a connecting rod, and a locking rod. The clamp is used to hold a porcelain insulator. The pressure plate is spaced apart from the clamp along a first direction, and a wire pad is provided on the side of the pressure plate facing the clamp for placing the wire. The connecting rod extends along the first direction and is connected to both the clamp and the pressure plate. At least one of the clamp and the pressure plate is rotatably connected to the end of the connecting rod via a pivot. The pivot extends along a second direction, which is perpendicular to the first direction. The locking rod passes through the pressure plate, and its target end extends close to the clamp. The target end of the locking rod is used to lock or unlock with the clamp; when the locking rod is locked with the clamp, the wire fixing device is in the locked state, so that the relative position of the clamp and the pressure plate is fixed, thereby fixing and pressing the wire placed on the wire pad onto the porcelain insulator clamped in the clamp; when the locking rod is unlocked from the clamp, the wire fixing device is in the released state, and at least one of the clamp and the pressure plate can rotate relative to the end of the connecting rod via the rotating shaft, so that the locking rod disengages from the clamp.
[0005] The wire fixing device provided by this utility model is equipped with a clamp for holding the porcelain insulator, a pressure plate for placing the wire, a connecting rod for connecting the clamp and the pressure plate, and a locking rod for locking the relative position of the clamp and the pressure plate. When installing the wire, the installer can operate the clamp to hold the porcelain insulator, operate the pressure plate to place the wire on the wire pad, and operate the locking rod to lock the relative position of the clamp and the pressure plate, thereby firmly pressing the wire onto the porcelain insulator, which can improve the efficiency and stability of wire installation.
[0006] In some embodiments, the connecting rod passes through the clamp, and one end of the connecting rod near the pressure plate is rotatably connected to the pressure plate via the rotating shaft.
[0007] In some embodiments, the clamp includes a first clamping arm and a second clamping arm, each of which includes a fixed end and a free end. The fixed ends of the first clamping arm and the second clamping arm at least partially overlap in projection along the first direction. The connecting rod passes through both the fixed ends of the first clamping arm and the second clamping arm. The locking rod is used to lock the free ends of the first clamping arm and the second clamping arm by passing through both the first clamping arm and the second clamping arm simultaneously, when the free ends of the first clamping arm and the second clamping arm at least partially overlap in projection along the first direction, thereby achieving locking with the clamp and enabling the first clamping arm and the second clamping arm to cooperate in clamping the porcelain bottle.
[0008] In some embodiments, when the clamp holds the porcelain bottle, the inner wall contours of the first clamping arm and the second clamping arm are both semi-circular arcs. When the clamp holds the porcelain bottle, at least a portion of the inner wall of the first clamping arm and at least a portion of the inner wall of the second clamping arm abut against the outer surface of the porcelain bottle to jointly hold the porcelain bottle.
[0009] At least one of the free ends of the first clamping arm and the second clamping arm is provided with an adjustment structure, which is used to cooperate with the locking rod to adjust the clamping diameter of the clamp, so that the clamp can clamp porcelain bottles of different sizes.
[0010] In some embodiments, the adjustment structure includes a plurality of notches formed on the outer side of the free end of the corresponding clamping arm, the plurality of notches being distributed circumferentially along the corresponding clamping arm and all being adapted to the locking lever; when the locking lever is engaged with any of the notches of the corresponding clamping arm, it locks the free end of the corresponding clamping arm.
[0011] In some embodiments, both the first clamping arm and the second clamping arm include a first clamping segment and a second clamping segment; for each of the first clamping arm and the second clamping arm, the first end of the first clamping segment is the fixed end of the clamping arm, the second end of the first clamping segment is rotatably connected to the first end of the second clamping segment, and the second end of the second clamping segment is the free end of the clamping arm.
[0012] In some embodiments, the wire fixing device further includes a limiting block disposed at the target end of the locking rod;
[0013] The second end of the second clamping section of the first clamping arm is located on the side of the second clamping section of the second clamping arm closer to the pressure plate. The side of the second clamping section of the second clamping arm opposite to the second clamping section of the first clamping arm is provided with a limiting groove adapted to the limiting block. When the wire fixing device is in the locked state, the locking rod is locked in the notch, and at least a part of the structure of the limiting block is locked in the limiting groove to prevent the locking rod from running out of the notch.
[0014] In some embodiments, both the free ends of the first clamping arm and the free ends of the second clamping arm have N notches on their outer sides, where N is an integer greater than 1.
[0015] In some embodiments, a boss is provided at the first end of the first clamping segment of the second clamping arm, and the boss has a first through hole; a groove adapted to the boss is provided at the first end of the first clamping segment of the first clamping arm, and a second through hole communicating with the first through hole is provided in the groove; the connecting rod is simultaneously inserted into the first through hole and the second through hole.

It should be understood that such data can be interchanged where appropriate so that the embodiments of the present invention described herein can be implemented in orders other than those illustrated or described herein. Additionally, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.
[0044] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.
[0045] Please refer to the following: Figures 1-5 This utility model provides a wire fixing device 1, which includes a locked state and a released state. Figures 1-5 The locked state of the wire fixing device 1 is shown.
[0046] The wire fixing device 1 includes a clamp 10, a pressure plate 20, a connecting rod 30, and a locking rod 40.
[0047] The clamp 10 is used to hold the porcelain bottle (not shown in the figure).
[0048] The pressure plate 20 and the clamp 10 are along a first direction (e.g.) Figures 1-5 The pressure plate 20 is provided with a wire pad 21 on the side facing the clamp 10 (as shown in the X-axis direction). The wire pad 21 is used to place the wire (not shown in the figure).
[0049] The connecting rod 30 extends along the first direction and is connected to both the clamp 10 and the pressure plate 20. At least one of the clamp 10 and the pressure plate 20 is rotatably connected to the end of the connecting rod 30 via a rotating shaft 31. The rotating shaft 31 extends along a second direction (e.g., ...). Figures 1-5 The direction extends along the Y-axis (as shown), and the second direction is perpendicular to the first direction.
[0050] The locking rod 40 passes through the pressure plate 20, and the target end of the locking rod 40 extends to a position close to the clamp 10. The target end of the locking rod 40 is used to lock or unlock with the clamp 10.
[0051] When the locking rod 40 is locked to the clamp 10, the wire fixing device 1 is in the locked state, fixing the relative positions of the clamp 10 and the pressure plate 20, thereby fixing and pressing the wire placed on the wire pad 21 onto the porcelain insulator held in the clamp 10. When the locking rod 40 is released from the clamp 10, the wire fixing device 1 is in the released state, and at least one of the clamp 10 and the pressure plate 20 can rotate relative to the end of the connecting rod 30 via the rotating shaft 31, causing the locking rod 40 to disengage from the clamp 10.
[0052] The wire fixing device 1 provided by this utility model is provided with a clamp 10 for holding the porcelain insulator, a pressure plate 20 for placing the wire, a connecting rod 30 for connecting the clamp 10 and the pressure plate 20, and a locking rod 40 for locking the relative position of the clamp 10 and the pressure plate 20. When installing the wire, the installer can operate the clamp 10 to hold the porcelain insulator, operate the pressure plate 20 to place the wire on the wire pad 21, and operate the locking rod 40 to lock the relative position of the clamp 10 and the pressure plate 20, thereby firmly pressing the wire onto the porcelain insulator, which can improve the efficiency and stability of wire installation.
[0053] In some embodiments, the connecting rod 30 is connected to both the first end of the clamp 10 and the first end of the pressure plate 20. When the locking rod 40 is locked to the clamp 10, the locking rod 40 and the connecting rod 30 are parallel, and the locking rod 40 is connected to both the second end of the clamp 10 and the second end of the pressure plate 20. The first and second ends of the clamp 10 are located along a third direction (e.g., ...). Figures 1-5 The first and second ends of the connecting rod 30 are the two opposite ends along the third direction (shown in the Z-axis direction).
[0054] In some embodiments, the connecting rod 30 passes through the clamp 10, and one end of the connecting rod 30 near the pressure plate 20 is rotatably connected to the pressure plate 20 via the rotating shaft 31. In other embodiments, one end of the connecting rod 30 may be rotatably connected to the clamp 10 via a rotating shaft, and the other end may be rotatably connected to the pressure plate 20 via another rotating shaft.
[0055] In some embodiments, the clamp 10 includes a first clamping arm 11 and a second clamping arm 12. Both the first clamping arm 11 and the second clamping arm 12 have a fixed end and a free end. The fixed ends of the first clamping arm 11 and the second clamping arm 12 at least partially overlap in projection along the first direction. The connecting rod 30 passes through both the fixed ends of the first clamping arm 11 and the second clamping arm 12. The locking rod 40, when the free ends of the first clamping arm 11 and the second clamping arm 12 at least partially overlap in projection along the first direction, locks the free ends of the first clamping arm 11 and the second clamping arm 12 by passing through both with its target end, thereby locking them to the clamp 10 and allowing the first clamping arm 11 and the second clamping arm 12 to cooperate in clamping the porcelain bottle.
[0056] In some embodiments, when the clamp 10 holds the porcelain bottle, the inner wall contours of the first clamping arm 11 and the second clamping arm 12 are both semi-circular arcs. When the clamp 10 holds the porcelain bottle, at least a portion of the inner wall of the first clamping arm 11 and at least a portion of the inner wall of the second clamping arm 12 abut against the outer surface of the porcelain bottle to jointly hold the porcelain bottle.
[0057] At least one of the free ends of the first clamping arm 11 and the second clamping arm 12 is provided with an adjustment structure. The adjustment structure is used to cooperate with the locking rod 40 to adjust the clamping diameter of the clamp 10, so that the clamp 10 can clamp porcelain bottles of different sizes.
[0058] In this way, installers can use the wire fixing device 1 to fix different types of wires to different types of porcelain insulators, making it widely applicable.
[0059] In some embodiments, the free end of the first clamping arm 11 is provided with a first adjustment structure 1122, and the free end of the second clamping arm 12 is provided with a second adjustment structure 1222. The first adjustment structure 1122 includes N first notches formed on the outer side of the free end of the first clamping arm 11, the N first notches being distributed circumferentially along the first clamping arm 11 and all adapted to the locking lever 40. The second adjustment structure 1222 includes N second notches formed on the outer side of the free end of the second clamping arm 12, the N second notches being distributed circumferentially along the second clamping arm 12 and all adapted to the locking lever 40. Wherein, N is an integer greater than 1.
[0060] When the locking lever 40 is engaged in either the first notch of the first clamping arm 11 or either the second notch of the second clamping arm 12, it simultaneously locks the free end of the first clamping arm 11 and the free end of the second clamping arm 12.
[0061] For example, such as Figures 1-5 As shown, the free end of the first clamping arm 11 is provided with three first notches, and the free end of the second clamping arm 12 is provided with three second notches. Thus, by combining different first notches and second notches, the clamp 10 of the wire fixing device 1 can clamp five different types of porcelain bottles.
[0062] In other embodiments, only one of the first clamping arm 11 and the second clamping arm 12 may be provided with an adjustment structure, that is, the inner diameter of only one clamping arm is adjustable, while the inner diameter of the other clamping arm is not adjustable.
[0063] In other embodiments, the number of the first gap and the number of the second gap may also be different.
[0064] In some embodiments, both the first clamping arm 11 and the second clamping arm 12 include a first clamping segment and a second clamping segment; for each of the first clamping arm 11 and the second clamping arm 12, the first end of the first clamping segment in the clamping arm is the fixed end of the clamping arm, the second end of the first clamping segment in the clamping arm is rotatably connected to the first end of the second clamping segment in the clamping arm, and the second end of the second clamping segment in the clamping arm is the free end of the clamping arm.
[0065] Specifically, the first clamping arm 11 includes a first clamping segment 111 and a second clamping segment 112, and the second clamping arm 12 includes a first clamping segment 121 and a second clamping segment 122. The first end of the first clamping segment 111 is the fixed end of the first clamping arm 11, and the second end of the first clamping segment 111 is rotatably connected to the first end of the second clamping segment 112. The second end of the second clamping segment 112 is the free end of the first clamping arm 11. Similarly, the first end of the first clamping segment 121 is the fixed end of the second clamping arm 12, and the second end of the first clamping segment 121 is rotatably connected to the first end of the second clamping segment 122. The second end of the second clamping segment 122 is the free end of the second clamping arm 12.
[0066] Thus, a movable connection is reserved in the middle of each clamping arm, which allows the inner wall of the clamp 10 to fit more tightly against the outer surface of the porcelain bottle, further improving the firmness of the wire installation.
[0067] In some embodiments, the wire fixing device 1 further includes a limiting block 41, which is disposed at the target end of the locking rod 40.
[0068] The second end of the second clamping segment 112 of the first clamping arm 11 is located on the side of the second clamping segment 122 of the second clamping arm 12 near the pressure plate 20. A limiting groove 1221 adapted to the limiting block 41 is provided on the side of the second clamping segment 122 of the second clamping arm 12 opposite to the second clamping segment 112 of the first clamping arm 11. The limiting groove 1221 extends circumferentially along the first clamping arm 11.
[0069] When the wire fixing device 1 is in the locked state, the locking rod 40 is engaged in the notch, and at least a portion of the structure of the limiting block 41 is engaged in the limiting groove 1221 to prevent the locking rod 40 from running out of the notch.
[0070] Thus, through the cooperation between the locking rod 40 and the limiting groove 1221, the locking rod 40 and the clamp 10 can be locked more firmly, thereby further improving the stability of the wire installation.
[0071] In some embodiments, a boss 1211 is provided at the first end of the first clamping segment 121 of the second clamping arm 12, and the boss 1211 has a first through hole extending along the first direction. A groove 1111 adapted to the boss 1211 is provided at the first end of the first clamping segment 111 of the first clamping arm 11, and the groove 1111 has a second through hole communicating with the first through hole. The connecting rod 30 is simultaneously inserted into both the first through hole and the second through hole.
[0072] In some embodiments, the first adjustment structure 1122 may also be N third through holes disposed at the free end of the first clamping arm 11, and the second adjustment structure 1222 may also be N fourth through holes disposed at the free end of the second clamping arm 12.
[0073] When the locking rod 40 passes through any third through hole of the first clamping arm 11 and any fourth through hole of the second clamping arm 12, it simultaneously locks the free end of the first clamping arm 11 and the free end of the second clamping arm 12.
[0074] In some embodiments, the wire fixing device 1 further includes an operating handle 42, which is disposed at one end of the locking rod 40 near the pressure plate 20. The operating handle 42 is used to drive the locking rod 40 to move and / or rotate, so as to lock or unlock the locking rod 40 with the clamp 10.
[0075] In some embodiments, the operating handle 42 is threadedly connected to the locking rod 40. When it is necessary to lock the locking rod 40 and the clamp 10, the installer can tighten the operating handle 42 so that the operating handle 42 abuts against the surface of the pressure plate 20 away from the clamp 10, thereby causing the limiting block 41 to engage in the limiting groove 1221 along the first direction. When it is necessary to unlock the locking rod 40 and the clamp 10, the installer can loosen the operating handle 42 so that the operating handle 42 disengages from the clamp 10, and causes the limiting block 41 to move out of the limiting groove 1221 along the first direction.
[0076] In some embodiments, the surface of the wire pad 21 for placing the wire is provided with anti-slip teeth.
[0077] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
