Description

Technical Field

[0001] This utility model relates to the field of cable tray technology, and in particular to a cable tray. Background Technology

[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 are carriers for various cables. Figure 1 An exploded view of a cable tray commonly found in the prior art is shown. Figure 1 As shown, in existing cable tray technology, the cable trough and cable cover are initially fixed by inserting the cable cover into the four corner pins and the cable trough into the four corner holes. Then, bolts are used to secure the cable cover through threaded holes on the flanges on both sides of the cable trough, preventing the cable cover from being easily lifted from above and causing separation between the cable trough and the cable cover. When using the existing cable tray technology as a carrier for various cables, the cable cover, when installed on the cable trough, cannot prevent vertical separation by simply inserting it into the cable trough. Tools such as screwdrivers or electric screwdrivers are required to tighten the bolts. The entire installation and disassembly process is complex and requires bolts, resulting in a higher overall cost.

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

[0005] The main purpose of this utility model is to provide a cable tray that solves the technical problem in the prior art where, when the cable cover and cable trough are installed, the cable cover and cable trough cannot be prevented from separating in the vertical direction by plugging them together, and bolts are still required for fastening.

[0006] To achieve the aforementioned utility model objectives, this utility model proposes a cable tray, comprising a cable tray cover and a cable tray body. The cable tray cover includes two first side plates and a top plate. The two first side plates are located on both sides of the top plate and connected to the top plate to form a sliding groove. The cable tray body includes a second side plate and a supporting structure. One end of the two second side plates is connected through the supporting structure to form the tray body. Sliding strips are provided at the ends of the two second side plates away from the supporting structure, with protruding insertion holes on the sliding strips. The insertion holes are parallel to the horizontal plane of the sliding strips. Corresponding clearance holes are provided on the top plate, and pins are provided in the clearance holes. The cable tray cover and the cable tray body are connected by the pins and insertion holes.

[0007] Furthermore, the clearance hole is a rectangular hole, and the pins in the plurality of clearance holes are arranged in the same direction.

[0008] Furthermore, the second side plate is provided with several spaced-apart reinforcing bars.

[0009] Furthermore, at least two insertion holes are provided on the slider, and the insertion holes are on the same straight line and evenly distributed on the slider.

[0010] Furthermore, one end of the second side plate along its length is provided with a socket-type connection part, and the other end is provided with a first connection part. Both the socket-type connection part and the first connection part are provided with connection holes. Between several adjacent cable trays, the socket-type connection part of one second side plate is connected to the first connection part of another second side plate end to end by fasteners.

[0011] Furthermore, the connecting hole is an oval-shaped hole.

[0012] Furthermore, the socket-type connector is provided with a first lug, which is formed by extending the second side plate along the length direction, and the connecting hole is provided on the first lug.

[0013] Furthermore, the socket-type connector is provided with a second lug, which is formed by the support structure extending along the length direction.

[0014] Furthermore, the first side plate is provided with a first slot along its length, the first slot being away from the top plate, and the second side plate is provided with a corresponding second slot at the end away from the supporting structure, the second slot being provided along the length of the second side plate, and the first side plate and the second side plate are engaged by the first slot and the second slot.

[0015] Furthermore, the top plate and the first side plate are an integral structure, and the supporting structure and the second side plate are an integral structure.

The two first side plates are located on both sides of the top plate and connected to the top plate to form a sliding groove. The cable tray body includes a second side plate and a supporting structure. One end of the two second side plates is connected through the supporting structure to form the tray body. The ends of the two second side plates away from the supporting structure are bent and extended towards each other with sliding strips.

[0035] Please see Figures 2 to 10 In this embodiment, a cable tray 1 is provided, including a cable tray cover 10 and a cable tray body 11. The cable tray cover 10 includes two first side plates 100 and a top plate 101. The first side plates 100 are located on both sides of the top plate 101 and connected to the top plate 101 to form a groove. The cable tray body 11 includes two second side plates 110 and a support structure 111. One end of the two second side plates 110 is connected by the support structure 111 to form a tray body. A slide bar 1100 is provided at the end of the second side plate 110 away from the supporting structure 111, which is bent towards each other. The slide bar 1100 is provided with a protruding insertion hole 1101, which is parallel to the horizontal plane of the slide bar 1100. A corresponding clearance hole 1010 is provided on the top plate 101, and a pin 1011 is provided in the clearance hole 1010. The cable trough cover 10 and the cable trough body 11 are connected to the insertion hole 1101 through the pin 1011.

[0036] In this embodiment, the cable trough 11 is used to carry and protect the cable, and the cable trough cover 10 covers the cable trough 11, further protecting the cable and preventing external environmental influences on it. The cable trough cover 10 consists of a top plate 101 and two first side plates 100 on both sides. The first side plates 100 are connected to the top plate 101 to form a downward-opening groove. The groove is used to cooperate with the sliding strip 1100 on the cable trough 11, allowing the cable trough cover 10 to slide along the sliding strip 1100, while also strengthening the overall strength of the cable trough cover 10 and facilitating the closing of the cable trough cover 10 and the cable trough 11. The cable trough 11 consists of a support structure 111 and two second side plates 110 on both sides. One end of the two second side plates 110 is connected by the support structure 111, and the two second side plates 110 and the support structure 111 are connected together to form a U-shaped groove space to accommodate the cable.

[0037] In the above embodiments, the support structure 111 can be a crossarm structure, where two second side plates 110 are connected by several crossarms to form a ladder-type cable tray. Simultaneously, heat dissipation holes 1110 are formed between the crossarms. In actual use, the cables laid in the cable trough 11 can dissipate heat through the heat dissipation holes 1110 between the crossarms, eliminating the need for additional heat dissipation devices and resulting in greater energy efficiency. Alternatively, the support structure 111 can be a base plate structure, where two second side plates 110 are connected by a base plate to form a U-shaped trough. Similarly, several heat dissipation holes 1110 are evenly distributed on the base plate. In actual use, the cables laid in the cable trough 11 can dissipate heat through the heat dissipation holes 1110 on the base plate, eliminating the need for additional heat dissipation devices and resulting in greater energy efficiency. The second side plate 110 extends towards the supporting structure 111 at one end, with a sliding strip 1100 bent in opposite directions. The sliding strip 1100 has protruding insertion holes 1101 arranged horizontally to engage with the pins 1011 on the cable tray cover 10 for quick locking. The top plate 101 has corresponding clearance holes 1010, with pins 1011 installed inside. When the cable tray cover 10 is closed, the pins 1011 are inserted into the insertion holes 1101 on the sliding strip 1100, fixing the cable tray cover 10 to the cable tray body 11.

[0038] In the above embodiment, a socket 1101 is provided on the slide bar 1100 and the socket 1101 is parallel to the horizontal plane of the slide bar 1100. A clearance hole 1010 is provided on the top plate 101 and a pin 1011 is provided in the clearance hole 1010. The pin 1011 and the socket 1101 are connected in the horizontal direction, which can not only restrict the movement of the two in the horizontal direction, but also prevent the two from separating in the vertical direction. No bolt fixing is required, and the entire installation and disassembly operation is relatively simple.

[0039] Please see Figures 2 to 10 In one embodiment, the clearance hole 1010 is a rectangular hole, and the pins 1011 in the plurality of clearance holes 1010 are arranged in the same direction.

[0040] In this embodiment, the rectangular hole and the pin 1011 are formed by a stamping process. All the pins 1011 located in the clearance hole 1010 are arranged in the same direction to ensure that each pin 1011 can smoothly slide into the corresponding insertion hole 1101 on the slide bar 1100. In actual use, the cable tray cover 10 and the cable tray body 11 can be installed by simply pushing the cable tray cover 10 in the same direction, which simplifies the operation. At the same time, when it is necessary to open the cable tray cover 10 for maintenance, it is only necessary to push the cable tray cover 10 in the opposite direction to separate the cable tray cover 10 and the cable tray body 11, and the cable tray cover 10 can be easily removed for maintenance.

[0041] Please see Figures 2 to 10 In one embodiment, the second side plate 1100 is provided with a plurality of spaced-apart ribs 1106.

[0042] In this embodiment, each of the two second side plates 1100 is provided with a plurality of fastening ribs 1106, which are equally spaced and arranged in a straight line. The fastening ribs 1106 are protruding structures or recessed structures on the second side plates 1100, or any combination of protruding structures and recessed structures.

[0043] Specifically, the fastener 1106 is a structure in which one second side plate 110 protrudes in the direction away from the other second side plate 110, or a structure in which one second side plate 110 is recessed in the direction close to the other second side plate 110, or any combination of the above two structures.

[0044] In the above embodiments, the specific shape of the rib 1106 is not specifically limited, as long as it can enhance the stability of the second side plate 110 and effectively prevent the second side plate 110 from deforming under the action of external force.

[0045] Please see Figures 2 to 10 In one embodiment, the slide bar 1100 is further provided with a stamping hole 1107, which is formed when the insertion hole 1101 is manufactured by a stamping process.

[0046] In this embodiment, the insertion hole 1101 is formed by a stamping process. During stamping, the stamping proceeds from the side closest to the support structure 111 towards the side of the slide bar 1100 away from the support structure 111, forming the insertion hole 1101 aligned with the horizontal direction of the slide bar 1100, and a stamping hole 1107 penetrating the slide bar 1100. By using a stamping process to form the insertion hole 1101 on the slide bar 1100, the amount of material used can be reduced without affecting the structural strength, thus lowering the overall production cost.

[0047] Please see Figures 2 to 10 In one embodiment, at least two insertion holes 1101 are provided on the slider 1100, and the insertion holes 1101 are on the same straight line and evenly distributed on the slider 1100.

[0048] In this embodiment, the insertion holes 1101 are evenly distributed along the same straight line on the slide bar 1100, which ensures that the connection points between the cable tray cover 10 and the cable tray body 11 are evenly distributed, thereby enabling the entire structure to distribute stress more evenly when subjected to external pressure or load. By providing at least two insertion holes 1101 at both ends of the slide bar 1100, multiple fixing points can be provided, enhancing the connection strength between the cable tray cover 10 and the cable tray body 11.

[0049] Please see Figures 2 to 10In one embodiment, the second side plate 110 has a socket-type connecting portion 1102 at one end along its length and a first connecting portion at the other end. Both the socket-type connecting portion 1102 and the first connecting portion have connecting holes 1103. Between several adjacent cable trays 1, the socket-type connecting portion 1102 of one second side plate 110 is connected to the first connecting portion of another second side plate 110 by fasteners. The socket-type connecting portion 1102 is provided with a first lug 1108, which is formed by extending the second side plate 110 along its length. The connecting hole 1103 is provided on the first lug 1108.

[0050] In this embodiment, the socket-type connector 1102 adds connection points, allowing adjacent cable tray sections 1 to be easily connected together with bolts or other fasteners through the connection holes 1103 on the socket-type connector 1102. This not only simplifies the installation steps but also increases the installation speed, making it suitable for rapid on-site assembly. Specifically, the socket-type connector 1102 includes inward-folding and outward-folding structures. The inward-folding type refers to the first lugs 1108 of the two second side plates 110 being bent inwards and closer together. When two adjacent cable trays 1 are connected to the first connector via the socket-type connector 1102, the socket-type connector 1102 is inserted into the inner side of the first connector, and the connecting holes 1103 on both are connected by bolts and nuts. Conversely, the outward-folding type refers to the first lugs 1108 of the two second side plates 110 being bent outwards and farther apart. When two adjacent cable trays 1 are connected to the first connector via the socket-type connector 1102, the socket-type connector 1102 is inserted into the outer side of the first connector, and the connecting holes 1103 on both are connected by bolts and nuts. Specifically, the first lug 1108 is formed by bending the second side plate 110 inwards or outwards and extending along its length.

[0051] In the above embodiment, the connecting hole 1103 is an oval hole. Compared to a circular hole, an oval hole provides greater installation tolerance. Because an oval hole has a certain degree of flexibility, it allows bolts or fasteners to be adjusted within a certain range, thereby adapting to the connection needs between cable tray sections of different lengths and reducing the requirements for installation accuracy. In this embodiment, an oval shape refers to a closed shape 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.

[0052] Furthermore, the socket-type connecting portion 1102 is provided with a second ear piece 1109, which is formed by the support structure 111 extending along the length direction. The two first ear pieces 1108 are integrally connected by the second ear piece 1109, or the second ear piece 1109 is respectively connected to the two second side plates 110, and the connecting portion extends along the length direction of the second side plate 110 to be flush with the end of the first ear piece 1108. For example, as... Figure 9 As shown, the second lug 1109 can be formed by bending the support structure 111 outward and extending it along the length of the second side plate 110, and is not connected to the first lugs 1108 on both sides. In actual use, this facilitates manual adjustment of the size of the socket formed by the first lugs 1108 and the second lugs 1109. Alternatively, the second lug 1109 can be formed by bending the support structure 111 inward and extending it along the length of the second side plate 110, and is connected to the first lugs 1108 on both sides. Figure 10 As shown, the second ear piece 1109 can also be formed by bending the connection points on both sides of the support structure 111 outwards and extending along the length direction of the second side plate 110. It can be understood that the second ear piece 1109 can also be formed by bending the connection points on both sides of the support structure 111 inwards and extending along the length direction of the second side plate 110, which will not be elaborated here.

[0053] In the above embodiments, when both the first ear piece 1108 and the second ear piece 1109 are inwardly folded, when two adjacent cable trays 1 are connected, the first ear piece 1108 of one cable tray is inserted into the first connecting part of the other cable tray, the inner sides of the first ear piece 1108 and the second side plate 110 are attached, and the second ear piece 1109 is attached to the inner side (upper surface) of the support structure 111. After aligning the first ear piece 1108 and the connecting hole 1103 on the first connecting part, the connection is fixed by bolts passing through the connecting hole 1103 and screws. When both the first ear piece 1108 and the second ear piece 1109 are outwardly flared, when two adjacent cable trays 1 are connected, the first connecting part of one cable tray is inserted into the socket-type connecting part 1102 of the other cable tray, the inner surface of the first ear piece 1108 and the outer surface of the second side plate 110 are attached, the bottom surface of the second ear piece 1109 is attached to the upper surface of the support structure 111, and after aligning the connecting hole 1103 on the first ear piece 1108 and the first connecting part, the connection is fixed by bolts passing through the connecting hole 1103 and screws.

[0054] Please see Figures 2 to 10 In one embodiment, the second side plate 110 is further provided with a grounding hole 1104. The grounding hole 1104 is a circular hole.

[0055] In this embodiment, the grounding hole 1104 is used to connect the grounding wire to ensure 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 a standard-sized grounding bolt or grounding clamp to ensure good electrical contact.

[0056] Please see Figures 2 to 10 In one embodiment, the first side plate 100 is provided with a first slot 1000 along its length direction, the first slot 1000 being away from the top plate, and the second side plate 110 is provided with a corresponding second slot 1105 at one end away from the support structure 111, the second slot 1105 being provided along the length direction of the second side plate 110, and the first side plate 100 and the second side plate 110 being engaged by the first slot 1000 and the second slot 1105.

[0057] In this embodiment, the first slot 1000 and the second slot 1105 can respectively enhance the structural strength of the first side plate 100 and the second side plate 110. In actual use, the first slot 1000 and the second slot 1105 can be manufactured by stamping. The first slot 1000 on the first side plate 100 is recessed into the inner side of the first side plate 100, and the second slot 1105 on the second side plate 110 is recessed into the inner side of the second side plate 110. By pressing the first slot 1000 on the first side plate 100 into the second slot 1105 on the second side plate 110, the first side plate 100 and the second side plate 110 are engaged in a direction perpendicular to the length direction of the second side plate 110.

[0058] Please see Figures 2 to 10 In one embodiment, the top plate 101 and the first side plate 100 are an integral structure, and the support structure 111 and the second side plate 110 are an integral structure.

[0059] In this embodiment, the connection between the support structure 111 and the second side plate 110, as well as the top plate 101 and the first side plate 100, is preferably achieved 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.

[0060] Please see Figures 2 to 10In one embodiment, chamfers are provided at the connection between the top plate 101 and the first side plate 100, the connection between the support structure 111 and the second side plate 110, and the connection between the slide bar 1100 and the second side plate 110.

[0061] In this embodiment, during the use of the cable tray 1, these connections will be subjected to various stresses. Right-angle connections are prone to stress concentration, which may lead to material deformation or even fracture when the stress accumulates to a certain extent. The chamfer design allows the stress to be gradually dispersed along the curved surface of the chamfer, avoiding excessive stress concentration at the sharp corners of the connection, thereby enhancing the overall structural stability and durability of the cable tray 1 and extending its service life.

[0062] The installation and removal process of the cable trough cover 10 and the cable trough body 11 is as follows:

[0063] Cable tray cover 10 and cable tray body 11 are fastened together: After aligning the clearance hole 1010 with the insertion hole 1101, the first slot 1000 on the first side plate 100 is inserted into the second slot 1105 on the second side plate 110. The cable tray cover 10 is slid, and the pin 1011 is inserted into the insertion hole 1101 to achieve the fastening and installation of the cable tray cover 10 and the cable tray body 11.

[0064] Disassembly of cable tray cover 10 and cable tray body 11: Slide cable tray cover 10 to separate pin 1011 from socket 1101. Disassembly of cable tray cover 10 and cable tray body 11 can be achieved by manually separating the cable tray cover 10 from the cable tray body 11 or by sliding the cable tray cover 10 to the cable tray body 11. During installation and disassembly, the directions of sliding cable tray body 11 are opposite.

[0065] In summary, a cable tray 1 according to an embodiment of this application includes a cable tray cover 10 and a cable tray body 11. The cable tray cover 10 includes a first side plate 100 and a top plate 101. The first side plate 100 is located on both sides of the top plate 101 and connected to the top plate 101 to form a groove. The cable tray body 11 includes a second side plate 110 and a support structure 111. One end of two second side plates 110 is connected by a plurality of support structures 111 to form a tray body. The end of the second side plate 110 away from the supporting structure 111 is provided with a sliding strip 1100 that bends towards each other. The sliding strip 1100 is provided with a protruding insertion hole 1101, which is parallel to the horizontal plane of the sliding strip 1100. The top plate 101 is provided with a corresponding clearance hole 1010, and a pin 1011 is provided in the clearance hole 1010. The cable trough cover 10 and the cable trough body 11 are connected to the insertion hole 1101 through the pin 1011. This technical solution provides an insertion hole 1101 on the slider 1100, with the insertion hole 1101 parallel to the horizontal plane of the slider 1100. An clearance hole 1010 is provided on the top plate 101, and a pin 1011 is provided in the clearance hole 1010. The pin 1011 and the insertion hole 1101 are connected horizontally, which not only restricts the movement of the two in the horizontal direction, but also prevents them from separating in the vertical direction. No bolts are required for fixing. The entire installation and disassembly operation is relatively simple. It can effectively solve the technical problem in the prior art that when the cable cover and the cable trough 11 are installed, the cable cover and the cable trough 11 cannot be prevented from separating in the vertical direction by insertion, and bolts are still required for fastening.

[0066] 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.
