Description

Technical Field

[0001] This utility model relates to the field of cable fixing technology, and more specifically, it relates to a cable fixing device for power supply and distribution secondary equipment. Background Technology

[0002] Secondary power distribution equipment is mainly used to monitor, control, and protect primary equipment to ensure the safe and stable operation of the power system. It includes relay protection devices, measurement and control devices, automation systems (such as SCADA), and communication management units, enabling real-time acquisition and logical judgment of voltage, current, and switch status. Secondary equipment obtains signals through instrument transformers to execute circuit breaking, alarms, or remote control, improving power supply reliability and supporting rapid fault isolation and system self-healing. It is a key component of the smart grid.

[0003] During the installation and use of secondary power distribution equipment, power supply and signal transmission are achieved through cables. When multiple sets of equipment are used together, there are many cables, so it is necessary to fix the cables of the secondary power distribution equipment.

[0004] In existing technologies, most cables for power distribution secondary equipment are fixed with adhesive coils or cable ties. This makes it difficult to flexibly adjust the fixing angle and position of the cables, and it also makes it difficult to disassemble and repair the cables after they are fixed.

[0005] For example, in the solutions provided in the cable fixing devices for secondary power supply and distribution equipment disclosed in relevant Chinese patent documents such as CN216214842U and CN212968965U, the cables of the secondary power supply and distribution equipment are mainly fixed by bolts. During installation and maintenance, the bolts need to be repeatedly disassembled and reassembled, which is not convenient to operate and affects the efficiency of installation, disassembly and maintenance. Utility Model Content

[0006] (a) Technical problems to be solved

[0007] To address the problems existing in the prior art, this utility model provides a cable fixing device for power supply and distribution secondary equipment, thereby solving the technical problem mentioned in the background art that the cable fixing device for power supply and distribution secondary equipment is not convenient for cable installation and maintenance, thus affecting operational efficiency.

[0008] (II) Technical Solution

[0009] To achieve the above objectives, this utility model provides the following technical solution:

[0010] A cable fixing device for a power supply and distribution secondary equipment includes a mounting frame, a lateral adjustment frame slidably mounted on the mounting frame, an angle adjustment frame rotatably mounted on the lateral adjustment frame, a locking seat mounted on the angle adjustment frame, a cable fixing frame locked on the locking seat, a cable fixing groove mounted on the cable fixing frame, and a protective pad inside the cable fixing groove.

[0011] The present invention is further configured such that the transverse adjustment frame is U-shaped, and the top and bottom ends of the transverse adjustment frame are both bent outward and provided with first spring pieces. A first engaging structure is provided between the first spring pieces and the mounting frame. A sliding strip is provided on the outer side of the first spring pieces. A sliding groove is provided inside the mounting frame. The sliding strip and the sliding groove are slidably engaged. During installation, the first spring pieces are engaged, and the transverse adjustment frame is slidably mounted on the mounting frame through the engagement of the sliding strip and the sliding groove. This allows for flexible adjustment of the installation position of the transverse adjustment frame on the mounting frame, which facilitates flexible adjustment of the fixed position of the cables of the power supply and distribution secondary equipment when they are fixed.

[0012] The present invention is further configured such that the first engaging structure includes a first engaging block, and a first engaging groove is provided on the inner wall of the mounting frame. The first engaging block and the first engaging groove engage with each other. When the transverse adjustment frame moves to a suitable position, the first spring is released, causing the first spring to drive the first engaging block to spring outward, thereby enabling the first engaging block to engage into the corresponding first engaging groove, thus realizing the installation and fixation of the transverse adjustment frame on the mounting frame.

[0013] The present invention is further configured such that a fixed column is provided on the outer side of the horizontal adjustment frame, and a rotating sleeve is provided on the inner side of the angle adjustment frame. The rotating sleeve is rotatably mounted on the fixed column, and a locking member is threaded on the rotating sleeve. The inner end of the locking member abuts against the side wall of the fixed column. When fixing the cables of the secondary power distribution equipment, the locking member can be loosened or tightened, allowing the rotating sleeve to rotate on the fixed column with the locking seat, thereby realizing flexible adjustment of the installation angle of the cable fixing frame. This allows for flexible adjustment of the fixing angle when fixing the cables of the secondary power distribution equipment. After adjusting to a suitable position, the locking member can be tightened, causing the locking member to move inward and press against the fixed column, thereby locking the rotating sleeve relative to the fixed column. Here, the rotating sleeve and the fixed column can be rotatably connected by a bearing, or a limited rotatable connection can be achieved by an existing arc-shaped groove structure, or the rotating sleeve can be directly movably mounted on the fixed column.

[0014] The present invention is further configured such that the cable holder is Ω-shaped and has a cable inlet at the bottom. In use, the cable of the secondary power distribution equipment to be fixed is inserted into the cable holder through the cable inlet, and then the cable holder is inserted into the clamping seat to achieve rapid cable fixing.

[0015] The present invention is further configured such that the two sides of the cable holder are bent outward and provided with second spring pieces, the outer side of the second spring pieces is provided with second locking blocks, and the inner wall of the locking seat is provided with a second locking groove. The second locking blocks and the second locking grooves are engaged with each other. The engagement between the second locking blocks and the second locking grooves realizes the limiting installation of the second spring pieces in the locking seat, thereby realizing the quick installation and disassembly of the cable holder on the locking seat. The cable holder is preferably made of a material with a certain elastic deformation effect, such as flexible plastic.

[0016] The present invention is further configured such that the tail ends of the first spring and the second spring are both provided with pinching ends. The pinching ends facilitate pinching during the disassembly of the wire fixing frame on the locking seat and the lateral adjustment frame on the mounting frame, so that the first locking block on the first spring is disengaged from the first locking groove and the second locking block on the second spring is disengaged from the second locking groove, thereby realizing the quick disassembly of the lateral adjustment frame on the mounting frame and the wire fixing frame on the locking seat.

[0017] The present invention is further provided that the mounting bracket has fixing holes, preferably strip-shaped holes. By passing bolts or other fasteners through the strip-shaped holes, the mounting bracket is fixed to the corresponding mounting interface. The setting of the strip-shaped fixing holes can reduce the overall weight and cost of the mounting bracket, and at the same time, facilitates flexible adjustment of the fixing position.

[0018] (III) Beneficial Effects

[0019] Compared with the prior art, this utility model provides a cable fixing device for power supply and distribution secondary equipment, which has the following beneficial effects:

[0020] 1. This utility model achieves multi-dimensional flexible adjustment of the fixed position and angle of cables in power distribution secondary equipment through the sliding cooperation between the horizontal adjustment bracket and the mounting bracket, the rotational design of the angle adjustment bracket, and the snap-fit ​​structure of the cable fixing bracket. The U-shaped structure of the horizontal adjustment bracket and the first spring piece, combined with the slider and groove, allow users to easily slide and lock the position; the angle adjustment bracket achieves stepless angle adjustment through the rotating sleeve and locking device to meet the needs of different wiring directions. The Ω-shaped design of the cable fixing bracket, combined with the cable inlet and the snap-fit ​​structure of the second spring piece, allows the cable to be quickly snapped in and fixed, and installation or removal can be completed without tools. This modular design significantly improves the efficiency of cable laying, and is especially suitable for multi-cable management in complex scenarios.

[0021] 2. Traditional cable fixing devices rely on bolts or cable ties, requiring tools for disassembly and easily damaging the cables. This invention employs a spring-loaded locking structure; simply squeezing the locking end releases the cable holder or lateral adjustment bracket, enabling instant cable removal and flexible adjustment of the installation position, greatly simplifying the installation and maintenance process. The addition of protective pads prevents cable abrasion, and the elastic material (such as flexible plastic) of the cable holder reduces fatigue during repeated opening and closing. The locking design of the fixing post and rotating sleeve further ensures stability after angle adjustment, preventing loosening.

[0022] 3. The strip-shaped fixing hole design of the mounting bracket in this utility model reduces the overall weight and material costs, while allowing for fine-tuning of the bolt installation position to adapt to different installation interfaces. The horizontal adjustment bracket and the cable fixing bracket adopt a split snap-fit ​​structure, reducing the use of metal parts. Mass production can be achieved through injection molding, reducing manufacturing costs. The matching precision requirements of the slide bar and the slide groove are low, and the processing is simple. The limiting snap-fit ​​between the first locking block and the first locking groove provides reliable fixation, avoiding the corrosion risk of traditional threaded structures. Furthermore, this utility model can be equipped with multiple sets of horizontal adjustment brackets and other related components on the mounting bracket as needed, and can be flexibly added and disassembled, resulting in high operational flexibility and convenience.

[0032] Please see Figures 1-5 A cable fixing device for secondary power distribution equipment includes a mounting frame 1, a horizontal adjustment frame 2 slidably mounted on the mounting frame 1, an angle adjustment frame 3 rotatably mounted on the horizontal adjustment frame 2, a locking seat 4 mounted on the angle adjustment frame 3, a cable fixing frame 5 locked on the locking seat 4, a cable fixing groove 6 mounted on the cable fixing frame 5, and a protective pad 7 inside the cable fixing groove 6. The protective pad 7 is preferably fixed to the inner wall of the cable fixing groove 6 by adhesive. The protective pad 7 can be made of rubber, silicone or polyurethane material.

[0033] Please see Figures 1-5 As one embodiment of the horizontal adjustment frame 2: the horizontal adjustment frame 2 is U-shaped, and the top and bottom ends of the horizontal adjustment frame 2 are bent outward and provided with first spring pieces 8. A first engaging structure is provided between the first spring pieces 8 and the mounting frame 1. A sliding strip 9 is provided on the outside of the first spring pieces 8. A sliding groove 10 is opened inside the mounting frame 1. The sliding strip 9 and the sliding groove 10 are slidably engaged. During installation, the first spring pieces 8 are pinched, and the horizontal adjustment frame 2 is slidably placed on the mounting frame 1 through the engagement of the sliding strip 9 and the sliding groove 10, so as to realize the flexible adjustment of the installation position of the horizontal adjustment frame 2 on the mounting frame 1. In this way, it is convenient to flexibly adjust the fixed position of the cables of the power supply and distribution secondary equipment when fixing them.

[0034] Please see Figures 1-5 As one embodiment of the first engaging structure: the first engaging structure includes a first engaging block 11, and a first engaging groove 12 is provided on the inner wall of the mounting frame 1. The first engaging block 11 and the first engaging groove 12 engage with each other. When the transverse adjustment frame 2 moves to a suitable position, the first spring 8 is released, so that the first spring 8 carries the first engaging block 11 outward, so that the first engaging block 11 can engage into the corresponding first engaging groove 12, thereby realizing the installation and fixation of the transverse adjustment frame 2 on the mounting frame 1.

[0035] Please see Figures 1-5 As one embodiment of the horizontal adjustment frame 2: a fixed column 13 is provided on the outer side of the horizontal adjustment frame 2, and a rotating sleeve 14 is provided on the inner side of the angle adjustment frame 3. The rotating sleeve 14 is rotatably mounted on the fixed column 13. A locking member 15 is threaded on the rotating sleeve 14. The inner end of the locking member 15 abuts against the side wall of the fixed column 13. When fixing the cables of the secondary power distribution equipment, the locking member 15 can be loosened and tightened so that the rotating sleeve 14 can rotate on the fixed column 13 carrying the locking seat 4, thereby realizing the flexible adjustment of the installation angle of the cable fixing frame 5, and thus realizing the flexible adjustment of the fixing angle when fixing the cables of the secondary power distribution equipment. After adjusting to the appropriate position, the locking member 15 can be tightened so that the locking member 15 moves inward and presses against the fixed column 13, thereby realizing the locking and fixing of the rotating sleeve 14 relative to the fixed column 13. Here, the rotating sleeve 14 and the fixed column 13 can be rotatably connected by a bearing, or the existing arc-shaped groove structure can be used to achieve a limited rotatable connection, or it can be directly movably sleeved on the fixed column 13.

[0036] Here, the sidewall of the fixed column 13 is provided with anti-slip texture or rubber pads to enhance friction.

[0037] Please see Figures 1-5 As one implementation of the cable holder 5: the cable holder 5 is Ω-shaped, and the bottom end of the cable holder 5 has a cable inlet 16. In use, the cable of the secondary power distribution equipment to be fixed is inserted into the cable holder 5 through the cable inlet 16. Then, the cable holder 5 is inserted into the clamping seat 4 to achieve quick cable fixing.

[0038] Please see Figures 1-5 As one embodiment of the cable holder 5: the cable holder 5 is provided with second spring pieces 17 bent outward on both sides. The second spring pieces 17 can be integrally injection molded with the cable holder 5. The outer side of the second spring pieces 17 is provided with a second locking block 18. The inner wall of the locking seat 4 is provided with a second locking groove 19. The second locking block 18 and the second locking groove 19 are mutually locked. The second spring pieces 17 are limited in the locking seat 4 by the mutual locking between the second locking block 18 and the second locking groove 19, thereby realizing the quick installation and disassembly of the cable holder 5 on the locking seat 4. The cable holder 5 is preferably made of a material with a certain elastic deformation effect, such as flexible plastic.

[0039] This utility model provides pinching ends 20 at the tail ends of both the first spring 8 and the second spring 17. The pinching ends 20 facilitate the pinching during the disassembly of the wire fixing frame 5 on the locking seat 4 and the horizontal adjustment frame 2 on the mounting frame 1, so that the first locking block 11 on the first spring 8 disengages from the first locking groove 12, and the second locking block 18 on the second spring 17 disengages from the second locking groove 19, thereby realizing the quick disassembly of the horizontal adjustment frame 2 on the mounting frame 1 and the wire fixing frame 5 on the locking seat 4.

[0040] Please see Figures 1-5 As one embodiment of the mounting bracket 1: the mounting bracket 1 is provided with fixing holes 21, which are preferably strip-shaped holes. By passing bolts or other fasteners through the strip-shaped holes, the mounting bracket 1 is fixed on the corresponding mounting interface. The setting of the strip-shaped fixing holes 21 can reduce the overall weight and cost of the mounting bracket 1, and at the same time, it is convenient to flexibly adjust the fixing position.

[0041] In summary:

[0042] In use, the mounting bracket 1 can be fixed to the corresponding cable fixing interface by external bolts, screws or other fasteners passing through the fixing hole 21.

[0043] Then, the pinching end 20 on the first spring piece 8 is pinched, and the horizontal adjustment frame 2 is slidably set on the mounting frame 1 through the cooperation of the slide bar 9 and the slide groove 10, so as to realize the flexible adjustment of the installation position of the horizontal adjustment frame 2 on the mounting frame 1.

[0044] After adjusting to the appropriate position, release the first spring piece 8, so that the first spring piece 8 carries the first locking block 11 outward, so that the first locking block 11 can be engaged in the corresponding first locking slot 12, thereby realizing the installation and fixation of the horizontal adjustment frame 2 on the mounting frame 1.

[0045] During subsequent installation, the position of the horizontal adjustment bracket 2 can be flexibly adjusted according to the above steps as needed, so that the cables of the power supply and distribution secondary equipment can be flexibly adjusted when fixed.

[0046] Afterwards, the installation angle of the clamping seat 4 can be adjusted as needed. If adjustment is required, loosen or tighten the locking piece 15 so that the rotating sleeve 14 can rotate on the fixed column 13 carrying the clamping seat 4, thereby realizing the flexible adjustment of the installation angle of the cable fixing frame 5, and thus realizing the flexible adjustment of the cable fixing angle when the cables of the secondary power distribution equipment are fixed.

[0047] After adjusting to the appropriate position, the locking part 15 can be tightened so that the locking part 15 moves inward and presses against the fixed post 13, thereby achieving the locking and fixing of the rotating sleeve 14 relative to the fixed post 13.

[0048] Next, the cables of the secondary power distribution equipment to be fixed are clamped into the cable holder 5 through the inlet 16;

[0049] Then, pinch the second spring 17 to snap the cable holder 5 into the locking seat 4. After that, release the second spring 17 so that the second locking block 18 snaps into the corresponding second locking slot 19, so as to realize the quick installation of the cable holder 5 on the locking seat 4 and the quick fixation of the cable. The cable holder 5 may have a slot structure, which is conducive to heat dissipation at the cable fixing position and reduces the material used for the cable holder 5.

[0050] Here, the cable holder 5 is compressed, which restricts the movement of the cable and fixes the cable inside the cable holder 5. At the same time, the protective pad 7 can also improve the stability of the cable inside the cable holder 5.

[0051] This invention allows for flexible and rapid disassembly of the cable holder 5 from the locking seat 4. During disassembly, simply pinch the two pinching ends 20 of the two sets of second spring pieces 17, causing the second spring pieces 17 to drive the second locking block 18 inward and disengage from the second locking slot 19, thus achieving rapid disassembly of the cable holder 5 from the locking seat 4. This enables rapid disassembly of cables in power distribution secondary equipment, improving overall maintenance and disassembly convenience.
