[0038] As Figure 1 , Figure 2 and Figure 3 shown, the present utility model provides a four-way connection structure for a cable tray, used for the four-way connection of a cable tray. The four-way connection structure of the cable tray includes a main tray 1, two side trays 2, four arc-shaped connecting pieces, and four corner connecting pieces 4.

[0039] The main tray 1 includes two first side plates 11 arranged side by side. A butting port is provided on the first side plate 11, and the butting ports on the two first side plates 11 are arranged opposite to each other. The two side trays 2 are respectively arranged on both sides of the main tray 1 and are respectively located at the two butting ports. The side tray 2 includes two second side plates 21 arranged side by side. The second side plate 21 intersects with the first side plate 11, and one end of the second side plate 21 extends to the first side plate 11 at the butting port.

[0040] Each corner connecting piece 4 is arranged inside the corner of the first side plate 11 and the second side plate 21. One part of the corner connecting piece 4 is connected to the first side plate 11, and the other part is connected to the second side plate 21. Each arc connecting piece is arranged outside the corner of the first side plate 11 and the second side plate 21. One part of the arc connecting piece is connected to the first side plate 11, and the other part is connected to the second side plate 21.

[0041] In the present utility model, the four-way connection structure of the cable tray is set as multiple components such as the main tray 1, two side trays 2, four arc connecting pieces, and four corner connecting pieces 4. Docking ports are arranged on the two first side plates 11 of the main tray 1, and the two side trays 2 are respectively docked with the two docking ports. When the second side plate 21 is docked with the first side plate 11 at the docking port, the first side plate 11 and the second side plate 21 are simultaneously connected by the arc connecting piece on the outside of the corner, and the first side plate 11 and the second side plate 21 are simultaneously connected by the corner connecting piece 4 on the inside of the corner, avoiding on-site cutting and welding. The overall operation is simple, the assembly is more convenient and fast, the installation efficiency is high, and the burden on the staff is reduced.

[0042] In addition, the corner connecting piece 4 is arranged inside the corner, avoiding the cable directly contacting the docking port of the first side plate 11 and directly contacting the end of the second side plate 21, and also avoiding burrs, gaps, protrusions and other results caused by on-site cutting and welding. The cable laying environment is better, and the cable is prevented from being cut and damaged when being dragged.

[0043] Furthermore, the corner connecting piece 4 and the arc connecting piece simultaneously connect the first side plate 11 and the second side plate 21 on the inside and outside of the corner, making the connection between the main tray 1 and the side tray 2 have good stability.

[0044] For the arc connecting piece, specifically, the arc connecting piece is an arc side plate 3. The arc side plate 3 has a larger connection area, facilitating the setting of more fasteners and improving the assembly stability.

[0045] In some embodiments of the arc side plate 3, such as Figure 2 、 Figure 4 shown, the upper parts of both ends of the arc side plate 3 are provided with first buckling parts 31 for respectively buckling the upper parts of the first side plate 11 and the second side plate 21. In this way, the arc side plate 3 can be buckled on the first side plate 11 and the second side plate 21, facilitating the preliminary assembly of the arc side plate 3 with the first side plate 11 and the second side plate 21 at the same time, and facilitating the assembly adjustment.

[0046] In some further embodiments of the arc side plate 3, such as Figure 4 shown, the lower parts of both ends of the arc side plate 3 are provided with limiting parts 32, and the two limiting parts 32 respectively extend towards the lower parts of the first side plate 11 and the second side plate 21 for limiting the position of the arc side plate 3.

[0047] The arc-shaped side plate 3 can be buckled on the first side plate 11 and the second side plate 21. The lower part of the arc-shaped side plate 3 is limited by the limiting part 32, so that the arc-shaped side plate 3 is limited up and down. Moreover, before locking the arc-shaped side plate 3 with the first side plate 11 and before locking the arc-shaped side plate 3 with the second side plate 21, the arc-shaped side plate 3 can be quickly disassembled and assembled, effectively improving the assembly efficiency.

[0048] In addition, the arc-shaped side plate 3 is buckled on the first side plate 11 and the second side plate 21 through the first buckling part 31 and the limiting part 32. At the same time, the slidability between the arc-shaped side plate 3 and the first side plate 11 is maintained, and the slidability between the arc-shaped side plate 3 and the second side plate 21 is maintained. In this way, the buckling position of the first end of the arc-shaped side plate 3 and the first side plate 11 can be adjusted by moving the arc-shaped side plate 3, so as to adjust the width of the transfer bridge. The buckling position of the second end of the arc-shaped side plate 3 and the second side plate 21 can be adjusted by moving the arc-shaped side plate 3, so as to adjust the length of the transfer bridge. That is, by arranging the first buckling part 31 and the limiting part 32 on the arc-shaped side plate 3, the transfer bridge has adjustability in width and length.

[0049] Of course, when the first buckling part 31 is provided on the arc-shaped side plate 3, the upper parts of the first side plate 11 and the second side plate 21 are also provided with matching structures. That is, the upper part of the first side plate 11 is provided with a first bending part adapted to the first buckling part 31, and the upper part of the second side plate 21 is provided with a second bending part adapted to the first buckling part 31.

[0050] In some embodiments of the corner connector 4, such as Figure 5 shown, the corner connector 4 includes a first connecting piece 41 and a second connecting piece 42. The first connecting piece 41 and the second connecting piece 42 are perpendicular to each other. The first connecting piece 41 is connected to the first side plate 11, and the second connecting piece 42 is connected to the second side plate 21.

[0051] Furthermore, locking holes 43 are provided on the first connecting piece 41 and the second connecting piece 42 for locking the first side plate 11 and the second side plate 21.

[0052] For the aforementioned first side plate 11, specifically, a first longitudinal beam 111 is provided on the inner side of the first side plate 11. The first longitudinal beam 111 passes through the docking port. A second longitudinal beam 211 is provided on the inner side of the second side plate 21. The second longitudinal beam 211 extends to the docking port. The first side plate 11 and the second side plate 21 are usually sheet metal structures. After their dimensions exceed a certain length, there is a problem of insufficient strength, while the first longitudinal beam 111 and the second longitudinal beam 211 can improve the strength of the first side plate 11 and the second side plate 21.

[0053] In some embodiments of the main bridge 1 and the side bridge 2, such as Figure 1As shown in the figure, the main cable tray 1 further includes a plurality of first connecting rods 12, and both ends of the first connecting rod 12 are respectively arranged on two first longitudinal beams 111. The side cable tray 2 further includes a plurality of second connecting rods 22, and both ends of the second connecting rod 22 are respectively arranged on two second longitudinal beams 211. The first connecting rod 12 can maintain the distance between two first side plates 11 on the main cable tray 1, improving the strength of the main cable tray 1. The second connecting rod 22 can maintain the distance between two second side plates 21 on the side cable tray 2, improving the strength of the side cable tray 2.

[0054] In some embodiments of the four-way connection structure of the cable tray, the four-way connection structure of the cable tray further includes a plurality of fasteners. Some fasteners are arranged at the connection between the arc-shaped connecting piece and the first side plate 11 for fastening the arc-shaped connecting piece and the first side plate 11. Some fasteners are arranged at the connection between the arc-shaped connecting piece and the second side plate 21 for fastening the arc-shaped connecting piece and the second side plate 21. Some fasteners are arranged at the connection between the corner connecting piece 4 and the first side plate 11 for fastening the corner connecting piece 4 and the first side plate 11. Some fasteners are arranged at the connection between the corner connecting piece 4 and the second side plate 21 for fastening the corner connecting piece 4 and the second side plate 21.

[0055] Specifically, the fastener includes a bolt and a nut. The bolt passes through the position to be fastened, and the nut locks the corresponding position. Through the fasteners, the stability between the arc-shaped connecting piece and the first side plate 11 is improved, and the stability between the arc-shaped connecting piece and the second side plate 21 is also improved. Also through the fasteners, the stability between the corner connecting piece 4 and the first side plate 11 is improved, and the stability between the corner connecting piece 4 and the second side plate 21 is improved.

[0056] The above embodiments are only the preferred embodiments of the present invention, and the scope of protection of the present invention cannot be limited thereby. Any non-substantial changes and substitutions made by those skilled in the art on the basis of the present invention belong to the scope of protection required by the present invention.
