Description

Technical Field

[0001] This utility model relates to the technical field of cable fixing, specifically a cable fixing device for a power distribution cabinet. Background Technology

[0002] High and low voltage switchgear are power distribution equipment used in power supply systems for power distribution, control, metering, and cable connection. Generally, power supply bureaus and substations use high voltage switchgear, which is then stepped down by transformers to the low voltage side and led out to low voltage switchgear. The low voltage switchgear then leads to various power distribution panels, control boxes, and switch boxes. Inside, there are power distribution devices that integrate switches, circuit breakers, fuses, buttons, indicator lights, meters, wires, and other protective devices to achieve the designed functional requirements.

[0003] There are many cables inside high and low voltage distribution cabinets, which requires the use of fixing devices to secure them. However, existing fixing devices can only fix one cable at a time. When multiple cables need to be fixed, multiple fixing devices need to be prepared at the same time. Installing multiple fixing devices wastes a lot of time. Therefore, a cable fixing device for distribution cabinets is needed to solve the above-mentioned problems. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a cable fixing device for power distribution cabinets, which solves the problems mentioned in the background art.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a cable fixing device for a power distribution cabinet, comprising two sets of mounting plates and mounting rods, the rear end of the mounting rods being connected to the two sets of mounting plates, each of the two sets of mounting plates being provided with two sets of mounting holes, and further comprising a fixing mechanism and an installation mechanism, the fixing mechanism being connected to the front end of the installation mechanism, both the fixing mechanism and the installation mechanism being provided in multiple sets, and the number of fixing mechanisms and installation mechanisms being the same, the installation mechanism being installed at the front end of the mounting rods, and the fixing mechanism being used to fix the cable;

[0008] The mounting mechanism includes a mounting block, a locking block, a first spring, and a pressing rod. The front end of the mounting rod has a mounting groove. The outer wall of the mounting block is slidably connected to the mounting groove. The top of the mounting block has a recess. The locking block is slidably connected to the recess. The top and bottom ends of the first spring are connected to the locking block and the recess, respectively. The top of the mounting groove has a locking slot. The top area of ​​the locking block engages with the locking slot. The locking slot and the mounting groove are connected by the same sliding groove. The bottom end of the pressing rod is connected to the top of the locking block. After the pressing rod presses down on the locking block, it can easily move out through the sliding groove. The top area of ​​the locking block has two sets of inclined surfaces. These inclined surfaces facilitate the squeezing of the locking block through the mounting groove, thus facilitating the mounting block's entry into the mounting groove. A fixing mechanism is installed at the front end of the mounting block.

[0009] Preferably, the fixing mechanism includes a fixing ring, an arc-shaped fixing plate, a tightening screw, and two sets of sliding rods. The fixing ring is connected to the front end of the mounting block, and the front end of the fixing ring is provided with a threaded hole. The tightening screw is threadedly connected to the threaded hole and rotatably connected to the arc-shaped fixing plate. The arc-shaped fixing plate is located inside the fixing ring. The two sets of sliding rods are slidably connected to the fixing ring, and one end of each set of sliding rods is connected to the arc-shaped fixing plate.

[0010] Preferably, it also includes an ejector rod and a second spring. The rear end of the mounting groove is provided with a connecting groove. The ejector rod is slidably connected to the inner side wall of the connecting groove. The two ends of the second spring are respectively connected to the ejector groove and the ejector rod. The front end of the ejector rod is in close contact with the rear end of the mounting block.

[0011] Preferably, a pressing plate is provided at the top of the pressing rod, and the diameter of the pressing plate is larger than that of the pressing rod.

[0012] Preferably, rubber pads are provided on the concave surface of the arc-shaped fixing plate and the inner sidewall of the fixing ring.

[0013] (III) Beneficial Effects

[0014] Compared with the prior art, the present invention provides a cable fixing device for a power distribution cabinet, which has the following advantages:

[0015] Firstly, by setting up multiple sets of fixing and installation mechanisms, with the number of fixing and installation mechanisms being the same, this device can simultaneously fix multiple cables. Compared to the traditional method where a single fixing device can only fix one cable, there is no need to prepare a separate fixing device for each cable, greatly reducing the number of fixing devices required and lowering costs.

[0016] Secondly, the structural design of the installation mechanism makes its installation and disassembly processes convenient and efficient. The mounting block is slidably connected to the mounting rod via a mounting groove. During installation, utilizing the two sets of inclined surfaces on the top of the mounting block, when the mounting block enters the mounting groove, the groove squeezes the mounting block, causing the mounting block to compress the first spring and enter the recess. After the mounting block is fully inside the mounting groove, the first spring returns to its original position, pushing the mounting block into the slot, achieving quick and easy locking and fixing of the mounting block without complicated operating steps. During disassembly, simply press the pressing rod to disengage the mounting block from the slot, and the mounting block can be removed from the mounting groove. The entire process is simple, saving the time spent installing and disassembling multiple fixing mechanisms and improving work efficiency.

[0017] Finally, this design, which integrates multiple fixing mechanisms on the same mounting rod, makes the fixing positions of multiple cables more concentrated and orderly, which facilitates the management and maintenance of cables, avoids the situation of cables being messy and disorderly, and also reduces the risk of failure caused by cables being tangled together.

[0023] 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. Example

[0024] Please see Figures 1-4A cable fixing device for a power distribution cabinet includes two sets of mounting plates 1 and mounting rods 2. The rear end of the mounting rods 2 is connected to the two sets of mounting plates 1. Each set of mounting plates 1 is provided with two sets of mounting holes 3. The device also includes:

[0025] The fixing mechanism and the installation mechanism are connected at the front end. Both the fixing mechanism and the installation mechanism are provided in multiple sets, and the number of fixing mechanisms and installation mechanisms is the same. The installation mechanism is installed at the front end of the installation rod 2, and the fixing mechanism is used to fix the cable.

[0026] The mounting mechanism includes a mounting block 4, a locking block 5, a first spring 6, and a pressing rod 7. The front end of the mounting rod 2 is provided with a mounting groove 8. The outer wall of the mounting block 4 is slidably connected to the mounting groove 8. The top end of the mounting block 4 is provided with a groove 9. The locking block 5 is slidably connected to the groove 9. The top and bottom ends of the first spring 6 are connected to the locking block 5 and the groove 9, respectively. The top end of the mounting groove 8 is connected to a locking slot 10. The top area of ​​the locking block 5 is engaged with the locking slot 10. The locking slot 10 and the mounting groove 8 are connected to the same sliding groove 11. The bottom end of the pressing rod 7 is connected to the top end of the locking block 5. After the pressing rod 7 presses down the locking block 5, it can be easily removed through the sliding groove 11. The top area of ​​the locking block 5 is provided with two sets of inclined surfaces 12. The two sets of inclined surfaces 12 facilitate the squeezing of the locking block 5 through the mounting groove 8, thereby facilitating the mounting block 4 to enter the mounting groove 8. The fixing mechanism is installed at the front end of the mounting block 4.

[0027] Firstly, by setting up multiple sets of fixing and installation mechanisms, with the number of fixing and installation mechanisms being the same, this device can simultaneously fix multiple cables. Compared to the traditional method where a single fixing device can only fix one cable, there is no need to prepare a separate fixing device for each cable, greatly reducing the number of fixing devices required and lowering costs.

[0028] Secondly, the structural design of the installation mechanism makes its installation and disassembly processes convenient and efficient. The mounting block 4 is slidably connected to the mounting rod 2 via the mounting groove 8. During installation, utilizing the two sets of inclined surfaces 12 on the top of the locking block 5, when the mounting block 4 enters the mounting groove 8, the mounting groove 8 squeezes the locking block 5, causing the locking block 5 to compress the first spring 6 and enter the groove 9. After the mounting block 4 is fully inside the mounting groove 8, the first spring 6 returns to its original position, pushing the locking block 5 into the slot 10, achieving quick locking and fixing of the mounting block 4 without complicated operating steps. During disassembly, simply press the pressing rod 7 to disengage the locking block 5 from the slot 10, allowing the mounting block 4 to be removed from the mounting groove 8. The entire process is simple, saving time spent installing and disassembling multiple fixing mechanisms and improving work efficiency.

[0029] Finally, this design, which integrates multiple fixing mechanisms on the same mounting rod 2, makes the fixing positions of multiple cables more concentrated and orderly, which facilitates the management and maintenance of cables, avoids the situation of cables being messy and disorderly, and also reduces the risk of failure caused by cables being tangled together.

[0030] Please see Figures 1-4 The fixing mechanism includes a fixing ring 13, an arc-shaped fixing plate 14, a tightening screw 15, and two sets of sliding rods 16. The fixing ring 13 is connected to the front end of the mounting block 4. The front end of the fixing ring 13 is provided with a threaded hole, and the tightening screw 15 is threadedly connected to the threaded hole. The tightening screw 15 is rotatably connected to the arc-shaped fixing plate 14, which is located inside the fixing ring 13. The two sets of sliding rods 16 are slidably connected to the fixing ring 13, and one end of each set of sliding rods 16 is connected to the arc-shaped fixing plate 14. The cooperation between the fixing ring 13 and the arc-shaped fixing plate 14, through the thread adjustment of the tightening screw 15, allows for flexible adjustment of the position of the arc-shaped fixing plate 14 according to cables of different diameters, achieving reliable fixing of cables of various specifications and solving the problem that traditional fixing devices are difficult to adapt to cables of different sizes. At the same time, the setting of the two sets of sliding rods 16 effectively restricts the movement trajectory of the arc-shaped fixing plate 14, preventing it from shifting or rotating during the tightening process, ensuring that the arc-shaped fixing plate 14 always maintains a stable fit with the cable, and enhancing the structural stability of the fixing mechanism. This adjustable fixing method allows the same fixing device to meet diverse cable fixing needs, expanding the applicability of the device and improving its versatility.

[0031] Please see Figures 1-4 The system also includes an ejector rod 17 and a second spring 18. A connecting groove is provided at the rear end of the mounting slot 8. The ejector rod 17 is slidably connected to the inner wall of the connecting groove. The two ends of the second spring 18 are connected to the ejector groove and the ejector rod 17, respectively. The front end of the ejector rod 17 is in close contact with the rear end of the mounting block 4. The addition of the ejector rod 17 and the second spring 18 facilitates the disassembly process of the mounting block 4, further optimizing disassembly efficiency. During disassembly, when the pressing rod 7 is pressed to disengage the locking block 5 from the locking groove 10, the elastic force of the second spring 18 pushes the ejector rod 17 forward. The ejector rod 17 then pushes the mounting block 4 to automatically pop out part of its length from the mounting slot 8, eliminating the need for manual pulling of the mounting block 4 and reducing operational steps and manpower consumption during disassembly. Especially in the case of densely installed multiple fixing mechanisms, this automatic ejection design effectively avoids the problem of the mounting block 4 being difficult to remove due to excessive tightness between it and the mounting slot 8, making the disassembly operation smoother and less strenuous, further shortening the disassembly time and improving overall work efficiency.

[0032] Please see Figures 1-4A pressing plate 19 is provided at the top of the pressing lever 7, and the diameter of the pressing plate 19 is larger than that of the pressing lever 7. The design of the pressing plate 19 enhances the convenience of disassembly operations. Because the diameter of the pressing plate 19 is larger than that of the pressing lever 7, its contact area with the operator's hand is larger, which can distribute the pressing force during the pressing process and avoid the situation where the hand is subjected to excessive force in a local area due to the small diameter of the pressing lever 7, making the pressing operation more effortless and comfortable. At the same time, the larger pressing plate 19 also makes it easier for the operator to quickly locate the pressing position, especially in the dimly lit or limited operating space of the distribution cabinet, which can reduce the time spent searching for the pressing lever 7 and improve the accuracy and efficiency of the disassembly operation.

[0033] Please see Figures 1-4 Rubber pads 20 are provided on the concave surface of the arc-shaped fixing plate 14 and the inner sidewall of the fixing ring 13. The rubber pads 20 serve a dual purpose: protecting the cable and enhancing the fixing effect. Firstly, the rubber material has good elasticity and flexibility, preventing direct hard contact between metal parts and the cable surface when the arc-shaped fixing plate 14 and fixing ring 13 come into contact with the cable. This prevents the cable insulation layer from being scratched or damaged by compression, extending the cable's service life and reducing the risk of safety accidents such as leakage caused by insulation damage. Secondly, the surface of the rubber pads 20 has high friction, increasing the static friction between the cable and the fixing mechanism. This effectively prevents the cable from shifting due to external pulling or vibration after fixing, ensuring the stability of the fixation and further improving the reliability of the cable fixing.

[0034] In summary, when using the cable fixing device for the distribution cabinet, the installation process begins with first fixing two sets of mounting plates 1 to their designated positions on the distribution cabinet via the mounting holes 3, ensuring stable installation of the mounting rod 2. Next, the fixing mechanism is assembled with the mounting rod 2: the mounting block 4 connected to the fixing mechanism is aligned with the mounting groove 8 at the front end of the mounting rod 2, and the mounting block 4 is pushed to slide into the mounting groove 8. During this process, the edge of the mounting groove 8 presses against the inclined surface 12 at the top of the locking block 5, causing the locking block 5 to compress the first spring 6 and retract into the groove 9. Once the mounting block 4 is fully inserted into the mounting groove 8, the first spring 6 resets and pushes the locking block 5 upwards, causing the top area of ​​the locking block 5 to engage with the groove 10, achieving quick locking and fixing of the mounting block 4 and the mounting rod 2. At this point, the pressing rod 7 is located within the sliding groove 11, completing the installation of one set of fixing mechanisms. By sequentially installing multiple sets of fixing mechanisms following the above steps, multiple sets of fixing mechanisms can be integrated onto the mounting rod 2.

[0035] When fixing cables, place the cables in the designated position of the fixing mechanism, and use the adjusting components of the fixing mechanism, such as the tightening screw 15, to clamp and fix the cables, thereby completing the orderly fixing of multiple cables.

[0036] When it is necessary to disassemble the fixing mechanism, press the pressing rod 7. The pressing rod 7 moves downward along the slide groove 11 and pushes the locking block 5 to compress the first spring 6, causing the locking block 5 to disengage from the locking groove 10 and retract into the groove 9. At this time, the locking relationship between the mounting block 4 and the mounting groove 8 is released, and the mounting block 4 can be directly pulled out from the mounting groove 8 to complete the disassembly of a single fixing mechanism. If multiple fixing mechanisms need to be disassembled, the above operation can be repeated.

[0037] Through the above implementation process, the device enables centralized fixing, rapid installation and disassembly of multiple cables, effectively improving the convenience, orderliness and efficiency of cable fixing.

[0038] The above embodiments merely illustrate specific implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
