[0035] Please refer to Figures 2 to 10 In the embodiment, a cable bridge 1 is provided, comprising a cable trough body 11 and a cable trough cover 10, the cable trough body 11 comprises a support mechanism 111 and two first side plates 110, the two first side plates 110 are fixedly connected to the two sides of the support mechanism 111 to form a trough body; the cable trough cover 10 comprises a top plate 100 and two second side plates 101, the two second side plates 101 are fixedly connected to the two sides of the top plate 100 to form a cover; one end of the first side plate 110 away from the support mechanism 111 is folded inward to form a side edge 1103 and a folded edge 1104, a bayonet 1102 is arranged at the connection position of the side edge 1103 and the folded edge 1104, and the inner side wall of the second side plate 101 is correspondingly provided with a buckle 1010; the cable trough body 11 and the cable trough cover 10 are clamped through the bayonet 1102 and the buckle 1010.

[0036] In the embodiment, the first side plate 110 has two, which are connected with the two sides of the support mechanism 111 respectively, and after being connected, a cable trough body 11 for accommodating cables is formed. The support mechanism 111 is a bottom support mechanism of the cable bridge 1, provides a placing plane for the cables, bears the weight of the cables, and ensures that the cables have stable placing space in the bridge. The first side plate 110 is fixed on the two sides of the support mechanism 111, and together with the support mechanism 111 forms a trough space for accommodating the cables, and plays a role in laterally restraining and protecting the cables to prevent the cables from sliding or being collided from the side. The cable trough cover 10 is used in cooperation with the cable trough body 11. It can be understood that when the cables are laid, the cables are placed in the cable trough body 11, and the cable trough cover 10 is covered above the cable trough body 11 to protect the cables from physical damage from the outside, such as dust, water droplets, foreign matter falling, etc. At the same time, selecting appropriate materials, such as metal materials, can also play a role in shielding electromagnetic interference to a certain extent. The second side plate 101 is on the two sides of the top plate 100, and together with the top plate 100 constitutes a cover. It can be understood that after the cable trough body 11 and the cable trough cover 10 are installed, the folded edge 1104 abuts against the surface of the top cover, and the side edge 1103 abuts against the inner surface of the second side.

[0037] In the above embodiments, the support mechanism 111 can be a cross arm structure, two first side plates 110 are connected by several cross arms to form a ladder type bridge, and at the same time, the heat dissipation holes 1111 are formed between the cross arms. In actual use, the cables arranged in the cable slot body 11 can be cooled through the heat dissipation holes 1111 between the cross arms, and no additional cooling device is needed, which is more energy-saving. The support mechanism 111 can also be a bottom plate structure, that is, two first side plates 110 are connected by a bottom plate to form a U-shaped slot body. Similarly, the bottom plate is uniformly provided with a plurality of heat dissipation holes 1111. In actual use, the cables arranged in the cable slot body 11 can be cooled through the heat dissipation holes 1111 provided on the bottom plate, and no additional cooling device is needed, which is more energy-saving. The bayonet 1102 provided at the connection between the folded edge 1104 and the side edge 1103 is used to connect with the buckle 1010 on the cable slot cover 10, so as to realize the clamping and covering of the cable slot body 11 and the cable slot cover 10. As shown in Figure 7 the bayonet 1102 is partially located on the folded edge 1104, and this part forms an avoidance position. In actual use, this part can ensure that the buckle 1010 smoothly passes through the bayonet 1102. It can be understood that the above technical solution realizes the connection of the cable slot cover 10 and the cable slot body 11 through the clamping of the buckle 1010 and the bayonet 1102 in the installation process of the cable slot cover 10 and the cable slot body 11. Compared with the bolt connection mode of the two, the operation of the present application is more convenient and fast, and no additional bolts are needed, which can reduce the use cost.

[0038] Please refer to Figures 2 to 10 In an embodiment, the included angle between the folded edge 1104 and the side edge 1103 is a right angle.

[0039] In this embodiment, the right angle structure makes the butt joint of the cable slot body 11 and the cable slot cover 10 more intuitive and accurate. During installation, the installer can more easily align the bayonet 1102 and the buckle 1010 to ensure accurate clamping. This clear structure design reduces the adjustment time and difficulty in the installation process, improves the installation efficiency, and reduces problems such as loose connection caused by improper installation. At the same time, it can ensure that after the installation of the cable slot body 11 and the cable slot cover 10, the folded edge 1104 is in abutment with the surface of the top cover, and the side edge 1103 is in abutment with the inner surface of the second side, so that the connection is more closely fitted, which can effectively block dust, water vapor and other external impurities from entering the inside of the cable bridge 1, protect the cables from erosion, and prolong the service life of the cables. More preferably, the right-angled folded edge 1104 and side edge 1103 structure can make full use of the internal space of the slot body, so that the cables are arranged more regularly and orderly in the slot body. Compared with other angles, the right angle structure will not form irregular spaces in the slot body, which is conducive to improving the capacity of the cables and the rationality of the wiring.

[0040] Please refer to Figures 2 to 10In an embodiment, the buckle 1010 comprises a clamping portion 1013 and a first connecting portion 1012, the clamping portion 1013 is fixedly connected with the second side plate 101 through the first connecting portion 1012; the first connecting portion 1012 is connected along the width direction of the second side plate 101, and the clamping portion 1013 extends along the length direction of the second side plate 101 away from one end of the first connecting portion 1012. The second side plate 101 is further provided with a punching hole 1011, the punching hole 1011 is arranged opposite to the buckle 1010, and one side of the connecting portion is fixedly connected with the punching hole 1011.

[0041] In the embodiment, the clamping portion 1013 is directly matched with the buckle opening 1102 on the cable groove body 11 as the part of the buckle 1010, and is mainly used for realizing the connection and fixation of the cable groove cover 10 and the cable groove body 11. The first connecting portion 1012 plays a role of a bridge, and stably connects the clamping portion 1013 to the second side plate 101. It ensures that the clamping portion 1013 has a reliable installation basis on the second side plate 101, so that the clamping portion 1013 can uniformly transmit force to the second side plate 101 when bearing the connecting force, avoids the clamping portion 1013 from falling off from the side plate due to force, and guarantees the normal play of the overall function of the buckle 1010. The punching hole 1011 is arranged on the second side plate 101 and opposite to the buckle 1010. In the embodiment, the buckle 1010 is arranged by using a punching process, and the punching is performed from the outside to the inside of the second side plate 101. After the punching, the punching hole 1011 is left on the second side plate 101, and the buckle 1010 is formed on the inside of the second side plate 101. It can be understood that the application does not limit the arrangement mode of the buckle 1010. For example, the buckle 1010 can also be arranged by integrally forming through die casting. Meanwhile, when the cable groove cover 10 is installed, the punching hole 1011 can help the installer to quickly and accurately align the buckle 1010 with the buckle opening 1102 on the cable groove body 11, and improve the installation efficiency. Meanwhile, it limits the position of the buckle 1010 on the second side plate 101, guarantees the consistency of the installation position of the buckle 1010 each time, and thus ensures that the buckle 1010 can accurately and correctly match with the buckle opening 1102 each time.

[0042] In the above embodiment, the clamping portion 1013 is fixed with the second side plate 101 through the first connecting portion 1012 and is connected along the width direction of the second side plate 101. This connection mode can guarantee that the clamping portion 1013 extends along the length direction of the second side plate 101 away from one end of the first connecting portion 1012, and further can guarantee that there is a moving space between the clamping portion 1013 and the second side plate 101. The moving space can guarantee that the cable groove body 11 and the cable groove cover 10 slide relative to each other.

[0043] In actual use, when the cable groove cover 10 and the cable groove body 11 are installed, the buckle 1010 is inserted into the card hole 1102 as a whole, and then the cable groove cover 10 is slid along the length direction of the second side plate 101. When the first connecting part 1012 abuts against the corresponding side of the card hole 1102, the cable groove cover 10 and the cable groove body 11 cannot slide, thereby realizing the clamping connection of the cable groove cover 10 and the cable groove body 11.

[0044] It should be noted that the clamping part 1013 of the embodiment can also be connected along the length direction of the second side plate 101. After connection, the end of the clamping part 1013 away from the first connecting part 1012 extends along the width direction of the second side plate 101. It can be understood that the buckle 1010 arranged in this way can only be inserted into the card hole 1102 when cooperating with the buckle 1010, and the cable groove cover 10 and the cable groove body 11 cannot slide along the length direction during insertion. Therefore, the application preferably adopts the arrangement mode of the clamping part 1013 connected along the width direction of the second side plate 101. It should also be noted that the clamping parts 1013 of the plurality of buckles 1010 extend along the length direction of the second side plate 101 uniformly, which can ensure that the movement space can ensure the relative sliding of the cable groove body 11 and the cable groove cover 10.

[0045] Please refer to Figures 2 to 10 In an embodiment, the plurality of buckles are arranged in the same direction.

[0046] In the embodiment, all the buckles 1010 are arranged in the same direction, which ensures that each buckle 1010 can be smoothly inserted into the card hole 1102. In actual use, after the buckle 1010 is inserted into the card hole 1102, the cable groove cover 10 can be pushed in a unified direction to complete the cooperation and installation of the cable groove cover 10 and the cable groove body 11, thereby simplifying the operation. At the same time, when it is necessary to open the cable groove cover 10 for maintenance, the cable groove cover 10 can be easily removed by pushing the cable groove cover 10 in the opposite direction to separate the cable groove cover 10 and the cable groove body 11, thereby facilitating maintenance.

[0047] Please refer to Figures 2 to 10In an embodiment, the first side plate 110 is provided with a socket joint 1106 at one end along the length direction and a second joint at the other end, both of which are provided with a connecting hole 1100. The socket joint 1106 of a first side plate 110 and the second joint of another first side plate 110 are connected end to end by fasteners between adjacent cable bridges 1. The socket joint is provided with a first lug formed by the first side plate extending along the length direction, and the connecting hole is provided on the first lug. The socket joint is provided with a second lug formed by the support mechanism extending along the length direction. The connecting hole 1100 is a waist-round hole. The first side plate 110 is also provided with a grounding hole 1101, which is a circular hole.

[0048] In the present embodiment, the socket joint 1106 is used for connection between adjacent cable bridges 1, and the socket joint 1106 increases the connection points, so that adjacent cable bridge 1 segments can be easily connected together by bolts or other fasteners through the connecting holes 1100 on the socket joint 1106, not only simplifying the installation steps, but also improving the installation speed, and being suitable for on-site rapid assembly. Specifically, the socket joint 1106 includes an inward folding and outward folding structure, wherein the inward folding refers to the first lug 1108 of the two first side plates 110 being relatively close to inwardly bending, when the adjacent two cable bridges 1 are connected by the socket joint 1106 and the second joint, the socket joint 1106 is inserted into the inner side of the second joint, and the connecting holes 1100 on both of them are connected by the cooperation of bolts and nuts; on the contrary, the outward folding refers to the first lug 1108 of the two first side plates 110 being relatively far away from outwardly bending, when the adjacent two cable bridges 1 are connected by the socket joint 1106 and the second joint, the socket joint 1106 is inserted into the outer side of the second joint, and the connecting holes 1100 on both of them are connected by the cooperation of bolts and nuts. Specifically, the first lug 1108 is formed by the first side plate 110 bending inwardly or outwardly along the length direction. As shown in FIG. 6, the first lug 1108 is formed by the first side plate 110 bending inwardly along the length direction, and the second lug 1107 is formed by the support mechanism 1105 bending outwardly along the length direction. Figure 8As shown, when the socket joint 1106 is outwardly expanded, the socket joint 1106 is bent outwardly relative to the first side plate 110. The connection hole 1100 is used for the connection between two cable bridges 1. When the adjacent cable bridges 1 are connected, the socket joint 1106 is clamped on the outside of the first side plate 110 of the other cable bridge 1, and the connection hole 1100 on the socket joint 1106 and the connection hole 1100 on the first side plate 110 away from the end of the socket joint 1106 are fixed by bolt connection. It should be noted that the number and position of the connection hole 1100 are not limited in the present application, and can be selected according to actual needs. In order to ensure that the laying engineering meets the requirements of safety specifications, a grounding hole 1101 is also provided on the first side plate 110, and there are two grounding holes 1101 on each first side plate 110.

[0049] In the present embodiment, the specific shape of the connection hole 1100 and the grounding hole 1101 is not limited, and can meet the actual design needs. Due to the complexity of the construction site in actual use and the possible slight size deviation of different bridge components in the manufacturing process, a certain installation adjustment space is required. The waist-round hole allows the connecting bolt or other connecting piece to have a certain range of movement in the hole, so that the installer can adjust the relative position between the two bridges to a certain extent, thereby more easily achieving accurate splicing and alignment of multiple cable bridges 1, improving installation efficiency, and reducing the problem of loose bridge connection or inability to install due to installation errors. In the present embodiment, the connection hole 1100 preferably adopts a waist-round hole. In the present embodiment, the waist-round hole refers to a closed figure formed by dividing a circle into two semicircular arcs that are mutually translated in opposite directions, and connecting the endpoints of the two semicircular arcs with two equal and parallel lines. Similarly, since the purpose of grounding is to ensure the safe operation of electrical equipment and to introduce the leakage current that may be generated into the ground. The structure of the round hole allows the grounding wire or grounding connecting piece to make uniform contact with the hole wall, reducing the contact resistance and ensuring the reliability and stability of grounding. Compared with other shaped holes, the round hole can provide tighter and more uniform contact when connected with a round cross-section grounding wire, thereby effectively reducing the grounding resistance and improving the electrical performance of the grounding system, better protecting the cable bridge 1 and related electrical equipment, and the round hole is a relatively easy-to-process shape. Whether using common processing methods such as drilling or punching, the processing precision of the round hole is easier to control, and the processing process is relatively simple, which can improve production efficiency and reduce production cost. Therefore, in the present embodiment, the grounding hole 1101 preferably adopts a round hole.

[0050] Please refer to Figures 2 to 10In an embodiment, the first side plate 110 is provided with a first clamping slot 1107 at one end away from the support mechanism 111 along the length direction, and the second side plate 101 is provided with a second clamping slot 1014 at one end away from the top plate along the length direction, and the first side plate 110 and the second side plate 101 are clamped through the first clamping slot 1107 and the second clamping slot 1014.

[0051] In the embodiment, the first clamping slot 1107 and the second clamping slot 1014 can be made by stamping forming, which can respectively strengthen the structural strength of the first side plate 110 and the second side plate 101. The first clamping slot 1107 on the first side plate 110 is recessed on the inner side of the first side plate 110, and the second clamping slot 1014 on the second side plate 101 is recessed on the inner side of the second side plate 101. By pressing the second clamping slot 1014 on the second side plate 101 into the first clamping slot 1107 on the first side plate 1107, the first side plate 110 and the second side plate 101 are clamped in the direction perpendicular to the length direction of the first side plate 110.

[0052] It should be noted that in the present application, the inner side of the first side plate 110 and the inner side of the second side plate 101 are divided according to the structure of the cable bridge 1, that is, the part used for installing cables in the cable bridge 1 is the inner side.

[0053] Please refer to Figures 2 to 10 In an embodiment, the side edge 1103 is provided with a buckle rib 1105.

[0054] In the embodiment, the buckle rib 1105 is used to strengthen the structural strength of the first side plate 110. It should be noted that the specific shape of the buckle rib 1105 is not limited in the present application, which can meet the actual design requirements. For example, a plurality of buckle ribs 1105 are arranged at equal intervals, and the plurality of buckle ribs 1105 are arranged in a straight line. The buckle rib 1105 is a protruding structure or a recessed structure on the side edge 1103, or any combination of the protruding structure and the recessed structure.

[0055] Please refer to Figures 2 to 10 In an embodiment, the support mechanism 111 and the first side plate 110 are an integral structure, and the top plate 100 and the second side plate 101 are an integral structure.

[0056] In the embodiment, the connection between the support mechanism 111 and the first side plate 110 and the connection between the top plate 100 and the second side plate 101 are preferably achieved by an integral molding process. The integral molding structure reduces the connection points between components. In a conventional splicing structure, the connection is often the weak part of the entire structure, which is prone to looseness, deformation, and even breakage under stress. The integral structure does not have these connection gaps, greatly enhancing the overall structural strength, enabling the cable bridge 1 to better withstand the weight of the cables, its own gravity, and possible external force impacts such as vibration, collision, etc., ensuring stable form and performance during long-term use.

[0057] Please refer to Figures 2 to 10 In an embodiment, the connection between the support mechanism 111 and the first side plate 110, the connection between the top plate 100 and the second side plate 101, and the connection between the side plate and the folded edge 1104 are all provided with chamfers.

[0058] During the use of the cable bridge 1, these connections will be subjected to various stresses. Right-angle connections are prone to stress concentration phenomena, which may cause material deformation or even breakage when stress accumulates to a certain extent. The provision of chamfers can gradually disperse stress along the curved surface of the chamfer, avoiding excessive stress concentration at the sharp corner of the connection, thereby enhancing the stability and durability of the overall structure of the cable bridge 1 and prolonging its service life.

[0059] The installation and removal process of the cable trough cover 10 and the cable trough body 11 is as follows:
