[0008] Furthermore, the first fixing plate is a plate structure with a plurality of first bottom grooves. The two sides of the first fixing plate along its length are respectively provided with a first connecting plate and a snap-fit ​​strip. The first connecting plate has a first through hole and can be fixed to a wall or other supporting structure by screws. The snap-fit ​​strip is used to snap the first snap-fit ​​plate.

[0009] Furthermore, the first snap-fit ​​plate is a plate structure with a plurality of first top wire grooves, which are adapted to the first bottom wire grooves to form wire grooves for preventing cables from passing through. Snap-fit ​​grooves adapted to the snap-fit ​​strips are also provided on both sides of the first snap-fit ​​plate. Through the matching snap-fit ​​grooves of the first snap-fit ​​plate and the snap-fit ​​strips of the first fixing plate, the first snap-fit ​​plate can be snapped onto the first fixing plate, thereby placing the cable within the space formed by the first top wire grooves and the first bottom wire grooves, protecting the straight-lined cable.

[0010] Furthermore, the first top groove and the first bottom groove are both semi-cylindrical grooves.

[0011] Furthermore, the second fixing plate includes a first main body and second connecting plates located on the four sides of the first main body; that is, the four corners of the second fixing plate are empty.

[0012] The front side of the first main board is provided with a plurality of first locking strips, and the spacing between two adjacent first locking strips in the horizontal and vertical directions is the same; the first locking strips are used to engage the conversion base;

[0013] The second connecting plate has a second through hole, which can be fixed to a wall or other supporting structure with screws; the second connecting plate also has a third through hole in the middle, which is used to connect the second snap-fit ​​plate.

[0014] Furthermore, the second snap-fit ​​plate includes a second main board body and snap-fit ​​posts located at the four corners of the second main board body, which snap-fit ​​to the four corners of the first main board body; the second main board body has a fourth through hole adapted to the third through hole; the second main board body is provided with a plurality of second snap-fit ​​strips, the spacing between two adjacent second snap-fit ​​strips in the horizontal and vertical directions is the same, and the second snap-fit ​​strips are used to snap-fit ​​the conversion base.

[0015] Furthermore, the first card strip and the second card strip have the same structure;

[0016] The first locking strip includes a column that is narrower on the inside and wider on the outside. A baffle is also provided at the bottom of the first locking strip to prevent the conversion base from falling off.

[0017] Furthermore, the back side of the conversion base is provided with a slot, which includes a first slot, a second slot and a third slot that are connected to each other. The first slot is a rectangular hollow slot; the second slot is adapted to the cylindrical shape of the first card strip; and the third slot is adapted to the shape of the baffle.

[0018] Furthermore, the length of the first card strip is half the length of the card slot.

[0019] Furthermore, the distribution of the conversion bases on the first motherboard is the same as that on the second motherboard, thereby forming a space to accommodate cables that run in a straight line or with a right-angle bend.

[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] This electrical engineering cable protection device features a combined design of straight-line protection units and transition protection units, allowing the entire device to flexibly adapt to the needs of cable layouts with different routes. The straight-line protection unit can be used independently to protect straight-line cables; the transition protection unit connects two perpendicularly positioned straight-line protection units, enabling a smooth transition at right-angle bends. By appropriately combining different numbers and types of transition bases, more complex cable routes can be created, such as multi-point bends and branch layouts, improving the applicability of this cable protection device in various electrical engineering scenarios.

[0022] Furthermore, the connections between the components primarily employ snap-fit ​​and screw fixing. These connection methods are simple and easy to operate, requiring no complex tools or cumbersome steps, making installation simple, convenient, and quick.

The snap-fit ​​engagement between the first snap-fit ​​plate and the first fixing plate, the second snap-fit ​​plate and the second fixing plate, as well as the snap-fit ​​engagement between the conversion base and the first or second locking strip, all enable quick and accurate connections, improving installation efficiency and saving construction time.

[0023] Furthermore, the tight space formed by the first top and bottom wire grooves in the linear protection unit, as well as the various wire groove shapes of the conversion base in the conversion protection unit, effectively protect the cable from external physical damage. At the same time, the tight connection between the various components prevents the cable from becoming loose or displaced within the device, ensuring the cable's stability throughout its use.

[0049] 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.

[0050] like Figures 1-19 As shown, this embodiment provides an electrical engineering cable protection device, including a straight protection unit and a conversion protection unit; the conversion protection unit is used to connect two straight protection units that are arranged perpendicularly to each other, and the conversion protection unit can also connect two straight protection units that extend in the horizontal direction or two vertical direction.

[0051] In this embodiment, as Figure 1 , Figure 2 , Figure 7 and Figure 8As shown, the linear protection unit includes a first fixing plate 1 and a first snap-fit ​​plate 2 snapped onto the first fixing plate 1. The first fixing plate 1 has a plurality of first bottom line grooves 11 arranged in a straight line. Specifically, the first fixing plate 1 is a plate structure with a plurality of first bottom line grooves 11. A first connecting plate 12 and a snap-fit ​​strip 13 are integrally arranged on both sides along the length of the first fixing plate 1. The first connecting plate 12 has a first through hole 14, through which screws can be passed to fix the first fixing plate 1 to a wall or other supporting structure, providing a stable support foundation for the entire linear protection unit. The snap-fit ​​strip 13 is used to snap onto the first snap-fit ​​plate 2. Correspondingly, the first snap-fit ​​plate 2 is a plate structure with a plurality of first top line grooves 21, which are adapted to the first bottom line grooves 11 to form grooves to prevent cable leakage. Snap-fit ​​grooves 22 adapted to the snap-fit ​​strip 13 are also arranged on both sides of the first snap-fit ​​plate 2. The first snap-fit ​​plate 2 can be snapped onto the first fixed plate 1 by means of the snap-fit ​​groove 22 of the first snap-fit ​​plate 2 and the snap-fit ​​strip 13 of the first fixed plate 1, thereby placing the cable in the space formed by the first top wire groove 21 and the first bottom wire groove 11, thus protecting the straight-line cable. The first top wire groove 21 and the first bottom wire groove 11 are both semi-cylindrical grooves, and their relative arrangement forms a cylindrical space that better conforms to the shape of the cable, accommodating and protecting it.

[0052] In this embodiment of the linear protection unit, the first through hole 14 on the first connecting plate 12 is fixed to the wall or other supporting structure with screws, or expansion bolts or other fasteners can be used to ensure that the entire linear protection unit is stably fixed during use and will not shift or fall off due to external forces, providing a stable protective environment for the cable. The snap-fit ​​strip 13 on the first fixing plate 1 provides a precise snap-fit ​​position for the first snap-fit ​​plate 2, allowing the first snap-fit ​​plate 2 to connect to the first fixing plate 1 quickly and accurately. The snap-fit ​​assembly is convenient and also ensures a tight connection, preventing the cable from being exposed due to an insecure connection. The space formed by the matching of the first top cable groove 21 and the first bottom cable groove 11 can tightly wrap the cable, effectively preventing the cable from being damaged by external factors such as collisions and squeezing. The semi-cylindrical groove design conforms to the natural shape of the cable, reducing the possibility of cable displacement within the groove and further improving the cable protection effect. The cooperation between the snap-fit ​​groove 22 and the snap-fit ​​strip 13 allows the first snap-fit ​​plate 2 to easily snap onto the first fixing plate 1 during installation, ensuring a firm and reliable connection and facilitating installation and disassembly.

[0053] In this embodiment, as Figures 1-6As shown, the conversion protection unit includes a second fixing plate 3 and a second snap-fit ​​plate 4. The second fixing plate 3 is detachably connected to several conversion bases 5, each conversion base 5 being used to form a straight extension or right-angle turn groove; the outer surface of the conversion base 5 is provided with one of the following grooves: horizontal groove, vertical groove, upper left bend groove, lower left bend groove, upper right bend groove, lower right bend groove, upper left and lower right bend groove, and lower left and upper right bend groove.

[0054] Specifically, the second fixing plate 3 includes a first main body 31 and second connecting plates 32 located on the four sides of the first main body 31, with the four corners of the second fixing plate 3 left unfilled. Several first locking strips 33 are arranged on the front side of the first main body 31, with the same spacing between adjacent first locking strips 33 in both the horizontal and vertical directions; the first locking strips 33 are used to engage the conversion base 5. The second connecting plate 32 has a second through hole 34, allowing it to be fixed to a wall or other supporting structure using screws. A third through hole 35 is also provided in the middle of the second connecting plate 32 for subsequent connection of the second locking plate 4.

[0055] The second latching plate 4 includes a second main board 41 and latching posts 42 integrally arranged at the four corners of the second main board 41. Each latching post 42 latches onto the four corners of the first main board 41. The second main board 41 has a fourth through hole 43 adapted to the third through hole 35. The second main board 41 is provided with a plurality of second latching strips 44, with the same spacing between two adjacent second latching strips 44 in both the horizontal and vertical directions. The second latching strips 44 are also used to latch onto the conversion base 5.

[0056] Furthermore, the first locking strip 33 and the second locking strip 44 have the same structure. Specifically, the first locking strip 33 includes a column that is narrower inside and wider outside, and a baffle 331 is also provided at the bottom of the first locking strip 33 to prevent the conversion base 5 from falling off.

[0057] In this embodiment of the conversion protection unit, the first locking strips 33 arranged on the front side of the first main board 31 have the same spacing in both the horizontal and vertical directions. This uniform layout provides multiple equidistant locking points for the conversion base, allowing for flexible selection of locking positions according to the actual cable routing requirements. This enables various cable routing options, such as straight extensions or right-angle turns, improving the flexibility and applicability of the device. The second through hole 34 on the second connecting plate 32 is used to fix the second fixing plate 3, ensuring its stable installation on the support structure. The third through hole 35 in the middle of the second connecting plate 32 is used to connect the second locking plate 4. This design allows the second fixing plate to not only support the conversion protection unit but also work in conjunction with the second locking plate to further enhance the structural strength and stability of the entire conversion protection unit.

[0058] The snap-fit ​​pins 42 of the second snap-fit ​​plate 4 snap onto the four corners of the first main board 31. This snap-fit ​​method enables a quick connection between the second snap-fit ​​plate 4 and the second fixing plate 3, forming a unified structure and improving the device's resistance to deformation. Simultaneously, the design of the snap-fit ​​pins 42 facilitates quick disassembly of the second snap-fit ​​plate when needed, simplifying maintenance and adjustment. The first snap-fit ​​strip 33 on the first main board 31 and the second snap-fit ​​strip 44 on the second main board 41 are compatible with the slots of the conversion base 5, ensuring a tight snap-fit ​​and preventing loosening or falling during use. The equidistant layout of the snap-fit ​​strips in both the horizontal and vertical directions provides multiple flexible snap-fit ​​points for the conversion base, enhancing the adaptability and stability of the conversion protection unit under different cable routing conditions.

[0059] In this embodiment, a slot is provided on the back side of the conversion base 5. The slot includes a first slot 51, a second slot 52, and a third slot 53 that are connected. The first slot 51 is a rectangular hollow slot, the second slot 52 is adapted to the cylindrical shape of the first locking strip 33, and the third slot 53 is adapted to the shape of the baffle 331. This design prevents the conversion base from falling off after being engaged, improving the safety and reliability of the device. The length of the first locking strip 33 is half the length of the entire slot. This structural design facilitates the engagement of the conversion base 5 with the first locking strip 33 or the second locking strip located in the second row or below. Engaging the conversion base 5 with the first locking strip or the second locking strip allows the conversion base 5 to be detachably connected to the second fixing plate 3 or the second engaging plate 4. Figures 9-17 As shown, since the outer side of the conversion base 5 is provided with one of the following types of wire grooves: horizontal wire groove, vertical wire groove, upper left bending wire groove, lower left bending wire groove, upper right bending wire groove, lower right bending wire groove, upper left and lower right bending wire groove, and lower left and upper right bending wire groove, by reasonably arranging different types of conversion bases, wire grooves that extend in a straight line or turn at right angles can be formed, so as to realize the laying and protection of cables in different directions.

[0060] In this embodiment, the distribution of the conversion base 5 on the first motherboard body 31 is the same as that on the second motherboard body 41, thereby forming a space for accommodating cables with straight or right-angle bends.

[0061] In this embodiment, the slot design of the interconnected first slot 51, second slot 52, and third slot 53 in the conversion base allows the conversion base 5 to fit tightly with the first locking strip 33 or the second locking strip 44. The outer surface of the conversion base 5 is provided with various shapes of grooves, including horizontal grooves, vertical grooves, and various bent grooves, which can meet the cable laying requirements in different directions, achieving straight extensions, right-angle turns, and other routing options. This diverse groove design enables this cable protection device to adapt to various complex cable laying scenarios, improving the versatility and practicality of the device.

[0062] The electrical engineering cable protection device provided in this embodiment features a combination of straight-line protection units and transition protection units, allowing the entire device to flexibly adapt to cable routing requirements with different directions. The straight-line protection unit can be used independently to protect straight-line cables; the transition protection unit connects two perpendicularly positioned straight-line protection units, enabling a smooth transition at right-angle bends. By appropriately combining different numbers and types of transition bases, more complex cable routing can be created, such as multi-point bends and branching arrangements. Figure 2 , Figure 18 , Figure 19 As shown, this improves the applicability of the cable protection device in various electrical engineering scenarios.

[0063] The electrical cable protection device provided in this embodiment primarily uses snap-fit ​​and screw fixing to connect its components. These connection methods are simple and easy to operate, requiring no complex tools or cumbersome steps, making installation simple, convenient, and quick. The corresponding through-hole structure design on the first fixing plate 1 and the second fixing plate 3 allows the cable protection device to be quickly fixed to a wall or other supporting structure. The snap-fit ​​cooperation between the first snap-fit ​​plate 2 and the first fixing plate 1, the second snap-fit ​​plate 4 and the second fixing plate 3, and the snap-fit ​​between the conversion base 5 and the first clip 33 or the second clip 44 all enable quick and accurate connections, improving installation efficiency and saving construction time.

[0064] In this embodiment, the tight space formed by the first top groove 21 and the first bottom groove 11 in the linear protection unit, as well as the various groove shapes of the conversion base 5 in the conversion protection unit, can effectively protect the cable and prevent it from being damaged by external physical forces. At the same time, the tight connection between the various components also prevents the cable from becoming loose or displaced inside the device, ensuring the stability of the cable throughout its use.

[0065] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the 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.
