Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cable installation, and particularly relates to a fastener for electric wire and cable installation. BACKGROUND

[0002] With the popularization of electric energy in China, cables are used in more and more places. Among them, power cables are used for transmitting and distributing electric energy. Power cables are often used for urban underground power grids, power station outgoing lines, internal power supply of industrial and mining enterprises, and underwater power transmission lines across rivers and seas. In the field of cable installation technology, the fixation of electric wires and cables is a key link to ensure the safety and reliability of power transmission.

[0003] However, traditional cable fasteners usually adopt simple clamping structures or fixed supports. These designs have significant limitations in complex installation scenarios, including the following technical defects:

[0004] First, existing fasteners adopt rigid designs and cannot adapt to the actual needs of cable routes. For example, in curved or inclined cable paths, fixed supports can only provide single-direction support, lacking multi-directional angle adjustment capabilities. This results in the need for installation personnel to repeatedly disassemble and reposition fasteners on site, which is not only inefficient but also may cause cable skin damage or loosening risks due to multiple adjustments. Worse still, some fasteners have fixed horizontal or vertical angles that cannot be fine-tuned with simple operations, forcing installation personnel to use additional tools or custom components, increasing construction complexity and costs.

[0005] Second, in cable installation, especially in long-distance erection or dense wiring environments, it is necessary to accurately control the spacing between multiple cables to maintain tension and avoid entanglement. However, existing fasteners mostly adopt fixed spacing designs or rely on manually adjustable bolts to achieve tightness, but this process is time-consuming and imprecise. For example, when adjusting the spacing, the bolts need to be loosened one by one, and then fixed after moving the position, which can easily lead to uneven tension. At the same time, there is a lack of reliable spacing locking mechanism, and cables are prone to relaxation under vibration or temperature changes, affecting long-term stability.

[0006] In view of this, the present application provides a fastener for electric wire and cable installation. SUMMARY

[0007] The present application provides a fastener for electric wire and cable installation, which solves the problem of lack of multi-directional angle adjustment capability in the fixed support of the prior art.

A threaded rod penetrating the top wall of the cable insertion base is movably connected to the inner side of the cable insertion base. A clamping plate is fixedly connected to the bottom end of the threaded rod. An adjusting element for driving the fixing frame to move vertically is provided on the inner side of the fixing frame. A snap-fit ​​module is provided on the outer side of each of the two cable insertion bases. A telescopic module for adjusting the distance between the two cable insertion bases is connected between the two snap-fit ​​modules.

[0009] Preferably, the positioning component includes a turntable fixed coaxially with the rotating seat. The outer edge of the turntable is provided with a plurality of slots arranged in a circumferential array. One end of the fixing frame is fixedly connected to a mounting plate. The top end of the mounting plate is threadedly connected to a screw rod that passes through the mounting plate. One end of the screw rod is rotatably connected to a positioning block that slides with any one of the slots. The other end of the screw rod is fixedly connected to a first rotating cap.

[0010] Preferably, both ends of the top of the clamp are fixedly connected to vertically arranged guide rods, and the top wall of the threading seat is provided with guide grooves that slide and cooperate with the two guide rods respectively.

[0011] Preferably, the adjusting component includes an internally threaded sleeve rotatably connected to the top of the threading seat, the internally threaded sleeve being fitted onto the outside of the lead screw and threadedly connected to the lead screw, a rotating shaft rotatably connected to the bottom end of the fixing frame and penetrating the side wall of the fixing frame, a first bevel gear fixedly connected to one end of the rotating shaft, a second rotating cap fixedly connected to the other end of the rotating shaft, and a second bevel gear meshing with the first bevel gear fixedly connected to the top of the internally threaded sleeve.

[0012] Preferably, the telescopic module includes a mounting sleeve, both ends of which are slidably connected to racks symmetrically distributed along the center of the mounting sleeve. A central gear is rotatably connected to the center of the inner side of the mounting sleeve. Both racks are connected to the central gear. A third rotating cap, coaxially fixed to the central gear, is rotatably connected to the top of the mounting sleeve. One end of each rack is fixedly connected to a connecting seat. Both ends of each connecting seat are fixedly connected to a locking block that slides in cooperation with the locking module.

[0013] Preferably, the bottom of the mounting sleeve is provided with a limiting component, the limiting component including a protective box fixedly connected to the bottom of the mounting sleeve, a ratchet fixed coaxially with the central gear is rotatably connected to the inner side of the protective box, and a pawl is rotatably connected to one end of the inner side of the protective box through a pin, the pawl engaging with the ratchet.

[0014] Preferably, the pawl is coaxially fixedly connected to a fourth rotating cap, and a torsion spring is sleeved on the pin of the pawl. The two ends of the torsion spring are respectively welded to the inner wall of the pawl and the mounting sleeve.

[0015] Preferably, the snap-fit ​​module includes a snap-fit ​​seat fixedly connected to the outside of the wire threading seat, the snap-fit ​​block slidably engages with the snap-fit ​​seat, both ends of the snap-fit ​​seat are slidably connected with slide rods penetrating the side wall of the snap-fit ​​seat, one end of each of the two slide rods is fixedly connected with a wedge-shaped limiting block that abuts against the snap-fit ​​block, and the other end of each of the two slide rods is fixedly connected with a pull block.

[0017] The working principle and beneficial effects of this invention are as follows:

[0018] 1. By rotating the rotating seat and the fixed frame, and with the turntable and slot structure of the positioning component, the horizontal angle of the cable tray can be infinitely adjusted. The mounting frame and the rotating seat are locked together by connecting bolts, and the longitudinal angle can be pre-adjusted. This allows for multi-directional angle adjustment of the cable tray, adapting to curved or inclined cable paths, reducing repeated disassembly, avoiding damage to the cable sheath, and improving installation efficiency.

[0019] 2. Rotating the third rotating cap drives the central gear, which in turn moves the symmetrical racks bidirectionally at equal distances. This adjusts the distance between the two cable threading seats to ensure cable tension. The ratchet and pawl mesh to prevent the central gear from reversing, precisely controlling the distance between multiple cables, maintaining tension balance, and avoiding slack caused by vibration / temperature difference.

[0020] 3. When installing the telescopic module, the wedge-shaped limiting block restricts the wedge-shaped limiting block and keeps it fixed to the card seat by engaging the locking block with the card seat. When disassembling, pulling the pull block outward causes the sliding rod to slide, which in turn causes the wedge-shaped limiting block to engage with the clearance groove, disengaging the wedge-shaped limiting block from the locking block. This allows the locking block to be directly removed from the card seat, thus achieving the disassembly of the entire telescopic module. The entire process of disassembling and assembling the telescopic module is convenient and can achieve "one-click" disassembly and assembly, greatly saving the actual disassembly and assembly time of the telescopic module.

[0032] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0033] like Figures 1 to 9As shown, this embodiment proposes a fastener for installing wires and cables, including two parallel wire-fixing modules 1. Each wire-fixing module 1 includes a cable guide 11 for inserting cables. A fixing frame 12 is fixedly connected to the top of the cable guide 11, and a rotating seat 13 is rotatably connected to the top of the fixing frame 12. A mounting frame 14 is provided inside the rotating seat 13, and a connecting bolt 15 is provided at the bottom end of the mounting frame 14. The mounting frame 14 is fixedly connected to the rotating seat 13 via the connecting bolt 15. One end of the fixing frame 12 is provided with a positioning element 16 for limiting the rotation of the rotating seat 13. The inner side of the 1 is movably connected to a lead screw 17 that passes through the top wall of the wire threading seat 11. The bottom end of the lead screw 17 is fixedly connected to a clamping plate 18. Both ends of the top of the clamping plate 18 are fixedly connected to vertically arranged guide rods 111. The top wall of the wire threading seat 11 is provided with guide grooves 112 that slide with the two guide rods 111 respectively. The inner side of the fixing frame 12 is provided with an adjusting member 19 for driving the fixing frame 12 to move in the vertical direction. The outer sides of the two wire threading seats 11 are provided with snap-fit ​​modules 3. The two snap-fit ​​modules 3 are connected to a telescopic module 2 for adjusting the distance between the two wire threading seats 11.

[0034] During installation, the mounting bracket 14 is connected to the rotating seat 13 via connecting bolts 15. Before tightening the connecting bolts 15, the rotating seat 13 can be rotated longitudinally. After determining the longitudinal angle, tighten the connecting bolts 15 to keep the mounting bracket 14 and the rotating seat 13 fixed. This allows the longitudinal angle of the cable guide 11 to be adjusted to meet the actual cable threading angle requirements. By operating the positioning component 16, the restriction on the rotating seat 13 is released, allowing the fixed bracket 12 and the rotating seat 13 to rotate relative to each other in the horizontal direction. This allows the horizontal angle of the cable guide 11 to be adjusted to meet the actual cable threading angle requirements. Then, the positioning component 16 is used for positioning. The entire structure can achieve multi-directional angles for the cable guide 11, meeting the cable fixing requirements of different angles in actual cable fixing scenarios, greatly improving the versatility of the device.

[0035] Furthermore, the positioning component 16 includes a turntable 161 coaxially fixed with the rotating seat 13. The outer edge of the turntable 161 is provided with a plurality of slots 162 arranged in a circumferential array. One end of the fixing frame 12 is fixedly connected to a mounting plate 163. The top end of the mounting plate 163 is threadedly connected to a screw 164 that passes through the mounting plate 163. One end of the screw 164 is rotatably connected to a positioning block 165 that slides with any one of the slots 162. The other end of the screw 164 is fixedly connected to a first rotating cap 166.

[0036] Rotating the first rotating cap 166 causes the screw 164 to rotate, resulting in relative sliding between the screw 164 and the mounting plate 163. This allows the positioning block 165 to engage or disengage from the slot 162. When it is necessary to adjust the horizontal angle of the threading seat 11, rotating the first rotating cap 166 causes the positioning block 165 to disengage from the slot 162. This allows the fixing bracket 12 and the rotating seat 13 to rotate relative to each other in the horizontal direction to adjust the horizontal angle of the threading seat 11. After determining the angle, rotating the first rotating cap 166 in the opposite direction causes the screw 164 to rotate in the opposite direction, allowing the positioning block 165 to engage with the corresponding slot 162, thus keeping the threading seat 11 stable at the current angle.

[0037] Furthermore, the adjusting member 19 includes an internally threaded sleeve 191 rotatably connected to the top of the threaded seat 11. The internally threaded sleeve 191 is fitted on the outside of the lead screw 17 and threadedly connected to the lead screw 17. The bottom end of the fixing frame 12 is rotatably connected to a rotating shaft 192 that passes through the side wall of the fixing frame 12. One end of the rotating shaft 192 is fixedly connected to a first bevel gear 193, and the other end of the rotating shaft 192 is fixedly connected to a second rotating cap 195. The top of the internally threaded sleeve 191 is fixedly connected to a second bevel gear 194 that meshes with the first bevel gear 193.

[0038] By rotating the second rotating cap 195, the rotating shaft 192 is driven to rotate, causing the first bevel gear 193 to rotate, which in turn causes the second bevel gear 194 to drive the internal threaded sleeve 191 to rotate. At this time, the internal threaded sleeve 191 and the lead screw 17 rotate relative to each other, allowing the lead screw 17 to move downward or upward. The downward movement of the lead screw 17 can drive the clamping plate 18 to clamp the cable downward. The entire cable fixing process is simple to operate and can quickly fix cables of different diameters, greatly saving cable fixing time.

[0039] Furthermore, the telescopic module 2 includes a mounting sleeve 21, with racks 22 slidably connected to both ends of the mounting sleeve 21 and symmetrically distributed along the center of the mounting sleeve 21. A central gear 23 is rotatably connected to the middle of the inner side of the mounting sleeve 21. Both racks 22 are connected to the central gear 23. A third rotating cap 24, coaxially fixed with the central gear 23, is rotatably connected to the top of the mounting sleeve 21. A connecting seat 25 is fixedly connected to one end of each of the two racks 22. Both ends of the two connecting seats 25 are fixedly connected to a locking block 26 that slides in cooperation with the locking module 3.

[0040] Rotating the third rotating cap 24 causes the central gear 23 to rotate, which in turn applies a meshing force to the two racks 22. This allows the two racks 22 to move towards or away from each other, thus enabling the two cable holders 11 to move towards or away from each other. This allows the spacing between the two cable holders 11 to be adjusted. After the cable is secured, the spacing between the two cable holders 11 can be increased to keep the cable taut, which facilitates the cable installation work.

[0041] Furthermore, a limiting component 27 is provided at the bottom of the mounting sleeve 21. The limiting component 27 includes a protective box 271 fixedly connected to the bottom of the mounting sleeve 21. A ratchet 272, which is coaxially fixed to the central gear 23, is rotatably connected to the inner side of the protective box 271. A pawl 273 is rotatably connected to one end of the inner side of the protective box 271 through a pin. The pawl 273 meshes with the ratchet 272. A fourth rotating cap 275 is coaxially fixedly connected to the pawl 273. A torsion spring 274 is sleeved on the pin of the pawl 273. The two ends of the torsion spring 274 are welded to the pawl 273 and the inner wall of the mounting sleeve 21, respectively.

[0042] During the process of adjusting the distance between the two cable holders 11 by rotating the third rotating cap 24 to drive the central gear 23, the pawl 273 can restrict the ratchet 272 and make it rotate only in one direction. Since the ratchet 272 is fixed coaxially with the central gear 23, the central gear 23 can only rotate in one direction. This prevents the two racks 22 from moving in opposite directions to increase the distance between the two cable holders 11, thus ensuring that the cable remains stably tensioned and improving the stability of the structure.

[0043] Furthermore, the snap-fit ​​module 3 includes a snap-fit ​​seat 31 fixedly connected to the outside of the wire threading seat 11. The snap-fit ​​block 26 is slidably engaged with the snap-fit ​​seat 31. Both ends of the snap-fit ​​seat 31 are slidably connected with slide rods 32 that penetrate the side wall of the snap-fit ​​seat 31. One end of each slide rod 32 is fixedly connected with a wedge-shaped limiting block 33 that abuts against the snap-fit ​​block 26. The other end of each slide rod 32 is fixedly connected with a pull block 34. The inner wall of the snap-fit ​​seat 31 is provided with a relief groove 35 that slidably engages with the wedge-shaped limiting block 33. A spring 36 is sleeved on the slide rod 32. Both ends of the spring 36 abut against the inner wall of the wedge-shaped limiting block 33 and the relief groove 35, respectively.

[0044] When installing the telescopic module 2, the wedge-shaped limiting block 33 restricts the wedge-shaped limiting block 26 by engaging the locking block 26 with the locking seat 31, thus keeping the locking block 26 and the locking seat 31 fixed. When disassembling, the sliding rod 32 is slidable by pulling the pulling block 34 outward, which causes the wedge-shaped limiting block 33 to engage with the relief groove 35, disengaging the wedge-shaped limiting block 33 from the locking block 26. This allows the locking block 26 to be directly removed from the inside of the locking seat 31, thereby achieving the disassembly of the entire telescopic module 2. The entire process of disassembling and assembling the telescopic module 2 is convenient and can achieve "one-click" disassembly and assembly, greatly saving the actual disassembly and assembly time of the telescopic module 2.

[0045] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. 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.
