Description

Technical Field

[0001] This utility model relates to a cable tray connection structure and belongs to the field of cable tray connection technology. Background Technology

[0002] In recent years, with the continuous increase in data center computing power, the amount of connecting cables between devices has been increasing, and the corresponding demand for mesh cable trays has also been rising, leading to wider and wider cable trays. However, due to the limited capabilities of manufacturers, this demand cannot be met. To address this issue, existing mesh cable tray installations often employ a double-row layout to accommodate ultra-large sizes. However, this method results in a significant amount of rewiring work when branching or splitting cables, greatly increasing the workload and impacting the construction progress.

[0003] Chinese patent document CN102808996A discloses a mesh cable tray for laying wires and cables. Although it discloses a connecting device that combines side connectors and bottom connectors to splice the cable trays into an extra-large mesh cable tray, it requires two connectors to connect the mesh cable trays. The connector structure is complex and also increases the installation process. Utility Model Content

[0004] To address the aforementioned issues, this utility model provides a cable tray connection structure. By modifying the structure of the cable tray connector, it can interlock with the mesh cable tray, allowing two mesh cable trays to be connected using only one connector. The structure is simple, easy to install and disassemble, and accelerates the installation speed on construction sites.

[0005] This utility model is achieved through the following technical solution: This utility model provides a cable tray connection structure, including: The sides and the bottom form a U-shaped structure; Card slots, which are symmetrically arranged on the side; A buckle, which engages with the slot and is located on one side of the slot, with an acute angle between the buckle and the side. A baffle is symmetrically arranged on the side and cooperates with the slot.

[0006] In one embodiment of this utility model, at least one card slot is provided, and the number of the buckles is adapted to the number of card slots.

[0007] In one embodiment of this utility model, the card slot includes a first card slot, a second card slot, and a third card slot. The second card slot is inclined on the side near the first card slot. The opening direction of the third card slot is perpendicular to the opening direction of the first card slot and the second card slot, and the opening directions of the third card slots located on both sides of the same side are opposite.

[0008] In one embodiment of this utility model, at least four first slots are provided, and the baffle is located between two adjacent first slots. The baffle can limit the cable tray wires that are locked between the first slots, ensuring that the cable tray will not disengage due to displacement of the cable tray wires after being securely locked.

[0009] In one embodiment of this utility model, the second card slot is inclined on the side closest to the first card slot.

[0010] In one embodiment of this utility model, the bottom of the slot is arc-shaped.

[0011] In one embodiment of this utility model, the buckle includes a first buckle, a second buckle, and a third buckle, which respectively cooperate with the first slot, the second slot, and the third slot.

[0012] In one embodiment of this invention, the buckle has an inclined surface on the side near the slot, which facilitates the sliding of the cable tray wire into the slot.

[0013] In one embodiment of this utility model, a limiting structure is included, which is located at both ends of the side. This limiting structure is used to define the position of the cable tray, ensuring that the cable tray is flush after assembly.

[0014] In one embodiment of this utility model, a first reinforcing rib and a second reinforcing rib are included, which are disposed on the bottom, with the first reinforcing rib perpendicular to the second reinforcing rib. The first and second reinforcing ribs can enhance the rigidity of the U-shaped structure, ensuring that the assembled mesh cable tray achieves the load-bearing capacity expected of a large-size cable tray.

[0015] Beneficial effects The cable tray connection structure provided by this utility model includes clips, slots, and baffles. The clips, slots, and baffles, combined with the steel wires of the cable tray, secure it and prevent disengagement or slippage during connection. This connector has a simple, one-piece design. Using this connector, cable trays can be assembled together, allowing smaller mesh cable trays to be combined into larger mesh cable trays, thus solving the problem of limited production capacity for manufacturers, facilitating transportation, and greatly improving economic efficiency. Furthermore, using only this connector, cable trays can be assembled without the need for multiple parts, simplifying the installation process and enabling rapid on-site installation, thus accelerating the installation speed at construction sites.

[0018] 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, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0019] In this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0020] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0021] like Figures 1 to 5 As shown, this application provides a cable tray connection structure, including a connector 100 and a cable tray 200. The connector 100 can be interlocked with the cable tray 200, allowing smaller mesh cable trays to be spliced ​​into larger mesh cable trays as needed. This structure can be quickly installed on site, accelerating the installation speed at the construction site. The smaller size of the mesh cable trays used for splicing solves the problem of limited production capacity of manufacturers, and is also easy to transport, greatly improving economic efficiency.

[0022] In some embodiments, the two sides of the connector 100 are bent inward to form a side 101 symmetrical about the bottom 102, and the bottom 102 and the side 101 form a U-shaped structure. Limiting structures 1 are provided at both ends of the connector 100. The limiting structures 1 are provided on the side 101 to limit the position of the cable tray 200 and ensure that the cable tray 200 can be flush after assembly.

[0023] In some embodiments, the connector 100 is provided with a buckle 4 and a slot 5 at its middle and both ends. The buckle 4 and the slot 5 cooperate to fix the steel wire of the cable tray 200 in the slot 5, thereby fixing the two cable trays 200 together. The slot 5 includes a first slot 51, a second slot 52, and a third slot 53, all of which are provided on the bent side of the connector 100. The bottom of the first slot 51 is semi-circular, and there are four of them, symmetrically arranged in the middle of the connector 100. The bottom of the second slot 52 is also semi-circular, and there are four second slots 52, symmetrically arranged on both sides of the first slot 51. The second slots 52 are inclined on the side closer to the first slot 51 to facilitate the sliding of the steel wire. There are also four third slots 53, symmetrically arranged at both ends of the connector 100, located on the sides of the second slots 52 away from the first slot 51. The bottom of the third slots 53 is also arc-shaped. The opening directions of the two third slots 53 on the same side are the same, while the opening directions of the third slots 53 on both sides of the same bend are opposite. The two third slots 53 with opposite opening directions are used to fix two different cable trays 200 respectively. A baffle 3 is provided between the two first slots 51 on the same bend. The baffle 3 can limit the cable tray steel wire that is locked between the first slots 51, ensuring that the cable tray 200 will not disengage due to displacement of the cable tray steel wire after it is firmly locked.

[0024] In some embodiments, the buckle 4 includes a first buckle 41, a second buckle 42, and a third buckle 43. The first buckle 41, the second buckle 42, and the third buckle 43 are all disposed on the bent side 101 of the connector 100 and bent inwards towards the inside of the connector 100, forming a certain angle with the bent side 101 of the connector 100. The buckle 4 has a beveled surface on the side near the slot 5 to facilitate the cable tray wire sliding into the slot 5. The first buckle 41 is correspondingly disposed on one side of the first slot 51, the second buckle 42 is correspondingly disposed on one side of the second slot 52, and the third buckle 43 is correspondingly disposed on one side of the third slot 53. By engaging the first buckle 41 with the first slot 51, the second buckle 42 with the second slot 52, and the third buckle 43 with the third slot 53, the cable tray wire can be fixed. When multiple cable trays 200 need to be assembled together, the cable tray wires of two cable trays 200 are pressed into the corresponding slots 5. When the cable tray wires are pressed into the slots 5, the clips 4 flip due to the pressure of the wires, allowing the wires to slide smoothly into the slots 5. After the cable tray wires are in place, the clips 4 return to their original position due to their elasticity, thus limiting the wires and ensuring that the connectors 100 can securely connect the two cable trays 200. A pressure plate 2 is provided on the side of the third slot 53 opposite to the third clip 43. The pressure plate 2, together with the slots 5 and clips 4, can limit the displacement of the cable tray wires and prevent disengagement. Together with the baffle 3, it ensures the firmness of the cable tray connection.

[0025] In some embodiments, the connector 100 further includes a first reinforcing rib 6 and a second reinforcing rib 7. There are two first reinforcing ribs 6, which are disposed at both ends of the connector 100. The second reinforcing rib 7 is installed in the middle of the connector 100 and is arranged perpendicular to the first reinforcing rib 6. The first reinforcing rib 6 and the second reinforcing rib 7 can enhance the rigidity of the U-shaped structure and ensure that the assembled mesh cable tray achieves the load-bearing capacity required for large-size cable trays.

[0026] The working principle of this utility model is as follows: During use, the cable trays 200 to be spliced ​​are symmetrically placed on both sides of the connector 100. By pressing the cable tray wires, the cable tray wires on the two cable trays 200 slide into the first slot 51, the second slot 52, and the third slot 53 respectively. During the sliding process, the buckle 4 flips. After the wire slides into the slot 5, its elasticity returns to its original position, securing the wire in the slot 5. The first slot 51 and the second slot 52 restrict the horizontal movement of the cable tray wires, while the third slot 53 and the third buckle 43 restrict the vertical movement of the cable tray wires, preventing them from coming loose under force. The limiting structure 1 constrains the cable tray wires, ensuring that the assembled cable trays are flush.

[0027] The connector 100 is integrally molded with a simple structure. It can assemble cable trays 200 together, allowing smaller mesh cable trays to be spliced ​​into larger mesh cable trays as needed. The steel wires of the cable tray are secured using slots 5, buckles 4, and a combination with baffles 3, preventing them from coming loose or slipping during connection. It also enables rapid on-site installation, accelerating the construction process. The smaller size of the mesh cable trays used for splicing also solves the problem of limited manufacturer production capacity, facilitating transportation and significantly improving economic efficiency.

[0028] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0029] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the invention 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.
