[0002] With the development of intelligent buildings, a single building often contains AC high-voltage systems, low-voltage systems, DC high-voltage systems, and various automation systems, such as building automation systems, office automation systems, and communication automation systems. Therefore, it is necessary to lay various types of cables simultaneously, including AC high-voltage cables, DC high-voltage cables, and low-voltage cables such as communication cables and control cables. These different types of cables need to be laid separately during the wiring design.

[0003] Cable trays serve as carriers for various cables, playing a vital role in supporting and protecting them. In existing cable tray systems, trays are typically fixed together by welding or bolts. However, during the fixing process, it's difficult to maintain a relatively stationary state between the trays, making the operation relatively complex.

[0004] Therefore, this application aims to provide a cable tray designed to solve the aforementioned problems. Utility Model Content

[0029] Please see Figures 1 to 4 This embodiment provides a cable tray 1, including a support mechanism 10 and two upright plates 11. The two upright plates 11 are fixedly connected to both sides of the support mechanism 10. One end of each upright plate 11 along its length is provided with a socket-type connecting portion 110, and the other end is provided with a first connecting portion 111. The socket-type connecting portion 110 has a slot 112 at the end of the upright plate 11 away from the support mechanism 10 along its width direction. The first connecting portion 111 is provided with a corresponding locking block 113. Adjacent cable trays 1 are connected to each other through the slot 112 and the locking block 113. The socket-type connecting portion 110 is provided with two first lugs 116, which are formed by extending the two upright plates 11 along their length direction. The first lugs 116 are respectively provided with the slots 112.

[0030] In this embodiment, the support mechanism 10 can be a crossarm structure, where two upright plates 11 are connected by several crossarms to form a ladder-shaped cable tray 1. Heat dissipation holes 100 are formed between the crossarms. In actual use, the cables are laid along the length of the cable tray 1 on the crossarms, and the cables can dissipate heat through the heat dissipation holes 100 between the crossarms, eliminating the need for additional heat dissipation devices and thus improving energy efficiency. The support mechanism 10 can also be a base plate structure, where two upright plates 11 are connected by a base plate to form a U-shaped trough. Similarly, several heat dissipation holes 100 can be evenly distributed on the base plate for cable heat dissipation.

[0031] In the above embodiment, the socket-type connecting part 110 and the first connecting part 111 are equipped with a connection point for mating connection between the two cable trays 1. Specifically, the socket-type connector 110 includes an inward-folding structure and an outward-folding structure. The inward-folding structure means that the first lugs 116 in the two upright plates 11 are relatively close and bent inward. When two adjacent cable trays 1 are connected through the socket-type connector 110 and the first connector 111, the socket-type connector 110 is inserted into the inner side of the first connector 111, and the connection is achieved by the slot 112 provided on the socket-type connector 110 cooperating with the block 113 provided on the first connector 111. Conversely, the outward-folding structure means that the first lugs 116 in the two upright plates 11 are relatively far apart and bent outward. When two adjacent cable trays 1 are connected through the socket-type connector 110 and the first connector 111, the socket-type connector 110 is inserted into the outer side of the first connector 111, and the connection is achieved by the slot 112 provided on the socket-type connector 110 cooperating with the block 113 provided on the first connector 111. Specifically, the first ear piece 116 is formed by bending the upright plate 11 inward or outward and extending it along the length direction.

[0032] In the above embodiments, the technical solution of this application provides a slot 112 on the socket-type connection part 110 and a block 113 on the first connection part 111. In actual use, adjacent cable trays 1 are connected end to end through the slot 112 and the block 113. After the slot 112 and the block 113 are engaged, the cable tray 1 can maintain relative stability during connection, and the operation process is relatively simple.

[0033] Please see Figures 1 to 4 In one embodiment, the socket-type connector 110 is provided with a second ear piece 117, which is formed by the support mechanism 10 extending along the length direction.

[0034] In this embodiment, the second ear piece 117 can be formed by bending the support mechanism 10 outward and extending it along the length direction of the upright plate 11, and is not connected to the first ear pieces 116 on both sides. In actual use, this facilitates manual adjustment of the size of the socket formed by the first ear pieces 116 and the second ear piece 117. Alternatively, the second ear piece 117 can be formed by bending the support mechanism 10 inward and extending it along the length direction of the upright plate 11, and is connected to the first ear pieces 116 on both sides.

[0035] In the above embodiments, when both the first ear piece 116 and the second ear piece 117 are inwardly folded, when two adjacent cable trays 1 are connected, the first ear piece 116 of one cable tray 1 is inserted into the first connecting part 111 of the other cable tray 1. The first ear piece 116 is attached to the inner side of the upright plate 11, and the second ear piece 117 is attached to the inner side (upper surface) of the support mechanism 10. The first ear piece 116 and the first connecting part 111 are engaged by the slot 112 and the block 113 to achieve the connection between the two adjacent cable trays 1. When both the first ear piece 116 and the second ear piece 117 are outwardly flared, when two adjacent cable trays 1 are connected, the first connecting part 111 of one cable tray 1 is inserted into the socket-type connecting part 110 of the other cable tray 1. The inner surface of the first ear piece 116 is in contact with the outer side of the upright plate 11, and the lower bottom surface of the second ear piece 117 is in contact with the upper surface of the support mechanism 10. The first ear piece 116 and the first connecting part 111 are connected by the slot 112 and the locking block 113 to realize the connection between the two adjacent cable trays 1.

[0036] Please see Figures 1 to 4 In one embodiment, the first ear piece 116 and the first connecting portion 111 are further provided with connecting holes 118, and adjacent cable trays 1 are fixedly connected by fasteners passing through the connecting holes 118. The connecting hole 118 is an oval hole.

[0037] In this embodiment, the connecting hole 118 is used to further fix the two connected cable trays 1 in conjunction with fasteners. That is, when the two adjacent cable trays 1 are engaged with the buckle through the slot 112, the two cable trays 1 are relatively stable along the length of the cable tray 1, but the slot 112 and the buckle block 113 can be separated in a direction perpendicular to the length of the cable tray 1. In actual installation, in order to ensure a more stable connection between the two through the slot 112 and the buckle block 113, the two cable trays 1 are also fixedly connected by aligning the connecting holes 118 on the first lug 116 and the first connecting part 111 and then fixing them together with fasteners passing through the connecting holes 118. The specific fastener is a bolt. When the bolt passes through the connecting hole 118, it is fixedly connected with the nut to fix the two cable trays 1 together.

[0038] In the above embodiment, the connecting hole 118 is an oval hole. Compared to a circular hole, an oval hole provides greater installation tolerance. Because of its flexibility, an oval hole allows bolts or fasteners to be adjusted within a certain range, thus accommodating the connection needs between cable tray sections of different lengths and reducing the requirements for installation precision. In this embodiment, an oval shape refers to a closed figure formed by dividing a circle through its center into two semicircular arcs that are translated in opposite directions, and connecting the endpoints of the two semicircular arcs with two parallel lines of equal length.

[0039] In the above embodiments, the connecting hole 118 on the first lug 116 is preferably an oval hole with its length direction along the length direction of the upright plate 110; the connecting hole 118 on the first connecting portion 111 is preferably an oval hole with its length direction along the width direction of the upright plate 110. This arrangement facilitates the adjustment of the relative positions of adjacent cable trays 1 during connection. That is, when the locking block 113 is undamaged, since the adjacent cable trays 1 are first engaged with the locking block 113 through the locking groove 112 during connection, the adjacent cable trays 1 cannot be adjusted in the length direction of the upright plate 110, but can be adjusted in the width direction of the upright plate 110. When the locking block 113 is damaged and cannot engage with the locking groove 112, the adjacent cable trays 1 can adjust their relative positions in the length and width directions of the upright plate 110 through the connecting hole 118 during connection.

[0040] Please see Figures 1 to 4 In one embodiment, the card block 113 includes a snap-fit ​​portion 1130 and a bending portion 1131. The bending portion 1131 is disposed on the first connecting portion 111 through the snap-fit ​​portion 1130, and adjacent cable trays 1 are connected to the snap-fit ​​portion 1130 through a card slot 112.

[0041] In this embodiment, the snap-fit ​​portion 1130 is the part directly connected to the upright plate 11 and is used to snap-fit ​​with the slot 112. The bent portion 1131 is integrally connected to the end of the snap-fit ​​portion 1130 away from the upright plate 11, and is used to limit the shaking of the first lug 11 held by the bent portion 1131 corresponding to the first connecting portion 111 when adjacent cable trays 1 are connected.

[0042] Please see Figures 1 to 4 In one embodiment, the connecting hole 118 on the first ear piece 116 is disposed below the slot 112, and the connecting hole 118 on the first connecting part 111 is disposed below the block 113.

[0043] In this embodiment, the first ear piece 116 is provided with two slots 112, and the first connecting part 111 is provided with two blocks 113, which is more conducive to stable engagement.

[0044] It should be noted that this application does not limit the orientation of the two locking blocks 113; they can be arranged in the same direction or in opposite directions. In actual use, the locking blocks 113 can be formed by stamping, that is, stamping can be done from the inside to the outside of the upright plate 11 or from the outside to the inside of the upright plate 11. It can be understood that when the locking blocks 113 are stamped from the inside to the outside of the upright plate 11, they can cooperate with the outwardly expanding socket-type connecting part 110; when the locking blocks 113 are stamped from the outside to the inside of the upright plate 11, they can cooperate with the inwardly expanding socket-type connecting part 110.

[0045] Please see Figures 1 to 4In one embodiment, the card block 113 is a rectangular card strip, and both the card slot 112 and the card strip are arranged along the width direction of the upright plate 11. Adjacent cable trays 1 are connected to each other through the card slot 112 and the card strip.

[0046] In this embodiment, the locking block 113 is a rectangular strip that can directly engage with the locking slot 112. Compared to the locking block 113 with a bent portion 1131, the locking strip structure can be integrally formed by a mold, eliminating the need for a stamping process and simplifying the structure.

[0047] It should be noted that in this embodiment, the slot 112 is also elongated, with its opening facing upwards. Specifically, the opening of the slot 112 is always located at the end of the first lug 116 in the width direction of the upright plate, away from the support mechanism 10. The slot 112 can be parallel to the width direction of the upright plate 11 or at an angle to it. It is understood that the consistent arrangement of the card strip and the slot 112 ensures that the card strip can be smoothly inserted into the slot 112. Preferably, the slot 112 in this application has a structure parallel to the width direction of the upright plate 11, facilitating the assembly of the card strip and the slot 112.

[0048] Please see Figures 1 to 4 In one embodiment, the upright plate 11 is provided with a plurality of spaced first ribs 114, and the support mechanism 10 is provided with a plurality of spaced second ribs 101.

[0049] In this embodiment, both upright plates 11 are provided with a plurality of first protruding ribs 114, which are equally spaced and arranged in a straight line. The first protruding ribs 114 are protruding structures or recessed structures on the upright plates 11, or any combination of protruding structures and recessed structures.

[0050] Specifically, the first rib 114 is a structure in which one vertical plate 11 protrudes away from the other vertical plate 11, or the rib 114 is a structure in which one vertical plate 11 protrudes towards the other vertical plate 11, or any combination of the above two structures.

[0051] In this embodiment, the support mechanism 10 can be a crossbeam structure or a base plate structure. When the support mechanism 10 is a crossbeam structure, the second protruding rib 101 is disposed on the crossbeam; when the support mechanism 10 is a base plate structure, the second protruding rib 101 is directly disposed on the base plate. It can be understood that the protrusion direction of the second protruding rib 101 can be towards the inside of the cable tray 1 or towards the outside of the cable tray 1. In this application, the inside of the cable tray 1 refers to the internal space of the trough formed by the support mechanism 10 and the two upright plates 11, and the outside of the cable tray 1 refers to the external space of the trough formed by the support mechanism 10 and the two upright plates 11.

[0052] In the above embodiments, the specific shape of the first rib 114 is not specifically limited, as long as it can satisfy the requirement of strengthening the stability of the upright plate 11 and effectively preventing the upright plate 11 from deforming under the action of external force; the specific shape of the second rib 101 is not specifically limited, as long as it can satisfy the requirement of strengthening the stability of the support mechanism 10 and effectively preventing the support mechanism 10 from deforming under the action of external force.

[0053] Please see Figures 1 to 4 In one embodiment, the upright plate 11 is provided with a groove 115 along its length, and the groove 115 is located at the end away from the support mechanism 10.

[0054] In this embodiment, the groove 115 further strengthens the upright plate 11. Simultaneously, the groove 115 is used to engage with the groove 115 on the cable tray 1's cover. In actual use, the cable tray 1 also needs to engage with the cover to further protect the cables; the cover is fixedly connected to the cable tray 1 via the groove 115.

[0055] Please see Figures 1 to 4 In one embodiment, the support mechanism 10 and the two upright plates 11 are an integral structure.

[0056] In this embodiment, the support mechanism 10 and the upright plate 11 are preferably connected using an integral molding process. The integral molding structure reduces the number of connection points between components. In traditional spliced ​​structures, the connection points are often the weakest points of the entire structure, prone to loosening, deformation, or even breakage under stress. The integral structure eliminates these connection gaps, greatly enhancing the overall structural strength. This allows the cable tray 1 to better withstand the weight of the cables, its own gravity, and potential external impacts such as vibration and collisions, ensuring stable shape and performance during long-term use.

[0057] In one embodiment, the upright plate 11 is also provided with a grounding hole, which is a circular hole.

[0058] In this embodiment, the grounding hole is used to connect the grounding wire, ensuring the electrical safety of the cable tray 1 system. By connecting the cable tray 1 system to the grounding system of the ground or building, static electricity accumulation can be effectively prevented, electromagnetic interference reduced, and a safe path for current discharge can be provided in the event of a fault, protecting the safety of personnel and equipment. The circular hole can typically fit tightly with standard-sized grounding bolts or grounding clamps, ensuring good electrical contact.

[0059] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural or procedural transformations made based on the content of the present utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present utility model.
