[0002] Trough-type cable trays are a type of fully enclosed cable tray that is widely used in various buildings and industrial facilities to support, protect, and manage cables and wires.

[0003] Patent CN222508668U discloses a trough-type cable tray. Cables are placed inside the tray housing, and one end of the top cover is inserted into a slot. When the slot moves to the locking block, a telescopic spring pushes the locking block into the slot, achieving initial fixation. Subsequently, the through hole on the top cover aligns with the threaded hole in the tray housing, and bolts are used for connection. During maintenance, the latch and lock of the closing mechanism separate, and the maintenance cover is rotated around the hinge to open the opening for cable maintenance. However, fixing the top cover of the aforementioned trough-type cable tray requires sliding it into the slot from one end. In practical applications, where cable trays are long or multiple trays are continuously installed, sliding the top cover into the tray housing from one end is difficult, thus posing certain challenges during cable tray installation. Utility Model Content

[0004] To overcome the shortcomings mentioned above, this utility model aims to provide a trough-type cable tray.

[0005] A trough-type cable tray includes a tray housing and a top cover fitted thereon; a connecting structure is provided between the tray housing and the top cover.

[0006] The connection structure includes a first connector that penetrates the side wall of the cable tray housing and a second connector located above the top cover. The outer side of the first connector is snapped into the bottom end of the second connector, and the ends of the first connector and the second connector that abut against each other are detachably connected.

[0007] Furthermore, the cable tray housing is an upward-opening groove structure, comprising a bottom surface and two housing side walls; the housing side walls are also fixedly connected to an inwardly extending top edge;

[0008] The bottom surface has a first through hole, and the two side walls of the shell have a second through hole and a perforation; the first connector passes through the perforation.

[0009] Furthermore, the top cover is a downward-facing groove-shaped structure, comprising a top surface and two top cover side walls; the top surface has mounting holes. When the top cover covers the cable tray housing, the inner side wall of the top cover precisely fits the top outer contour of the cable tray housing.

[0010] Furthermore, the first connecting member is an integral structure comprising a first groove, a middle horizontal plate, a first vertical plate, and a top horizontal plate, wherein the top horizontal plate has a first connecting hole; a baffle is provided at one end of the first groove; and the first groove has a through hole penetrating the side wall of the housing.

[0011] Furthermore, the second connector is an integral structure comprising an inverted T-shaped plate and a second horizontal plate, the second horizontal plate having a second connecting hole; fasteners are used to pass through the second connecting hole and the first connecting hole to connect the first connector and the second connector.

[0012] Furthermore, the bottom end of the inverted T-shaped plate is engaged with the first groove, and the baffle abuts against the bottom end of the inverted T-shaped plate;

[0013] The upper end face of the top horizontal plate abuts against the lower end face of the second horizontal plate, and the second connecting hole and the first connecting hole overlap vertically.

[0034] like Figures 1-3 As shown, this embodiment provides a trough-type cable tray, including a tray housing 1 and a top cover 2 mounted thereon. A connecting structure is provided between the tray housing 1 and the top cover 2, which enables the top cover 2 and the tray housing 1 to be detachably and flexibly connected.

[0035] In this embodiment, the cable tray housing 1 is an upward-opening groove structure, including a bottom surface 11 and two housing side walls 12; the housing side walls 12 are also fixedly connected to an inwardly extending top edge 13. A first through hole 111 is provided on the bottom surface 11, and a second through hole 121 and a through hole 122 are provided on the two housing side walls 12, wherein the first connector 3 in the connecting structure is installed through the through hole 122.

[0036] The top cover 2 is a downward-facing groove-shaped structure, including a top surface 21 and two top cover side walls 22; the top surface 21 has mounting holes 211. When the top cover 2 covers the cable tray housing 1, the inner side wall of the top cover 2 fits exactly against the top outer contour of the cable tray housing 1.

[0037] In this embodiment, as Figures 1-5 As shown, the connection structure includes a first connector 3 that penetrates the side wall 1 of the cable tray housing and a second connector 4 located above the top cover 2. The outer side of the first connector 3 is snapped into the bottom end of the second connector 4, and the ends of the first connector 3 and the second connector 4 that abut against each other are detachably connected.

[0038] Specifically, the first connector 3 is an integral structure comprising a first groove 31, a middle horizontal plate 32, a first vertical plate 33 and a top horizontal plate 34. The top horizontal plate 34 has a first connecting hole 341. A baffle 35 is provided at one end of the first groove 31. The first groove 31 passes through a through hole 122 in the side wall 12 of the housing.

[0039] The second connector 4 is an integral structure including an inverted T-shaped plate 41 and a second horizontal plate 42. The second horizontal plate 42 has a second connecting hole 421. Fasteners 5 pass through the second connecting hole 421 and the first connecting hole 341 to connect the first connector 3 and the second connector 4.

[0040] Furthermore, the bottom end of the inverted T-shaped plate 41 is engaged with the first groove 31, and the baffle 35 abuts against the bottom end of the inverted T-shaped plate 41; the upper end face of the top horizontal plate 34 abuts against the lower end face of the second horizontal plate 42, and the second connecting hole 421 and the first connecting hole 341 overlap vertically. The middle horizontal plate 32 abuts against the lower end face of the top edge 13. The top horizontal plate 34 is located inside the mounting hole 211 of the top cover 2, and the second horizontal plate 42 of the second connector 4 is located above the mounting hole 211 and can cover the mounting hole 211.

[0041] When cable maintenance is required, remove fastener 5 and then slide the second connector 4 out of the first groove 31 of the first connector 3. Then, remove the first connector 3 from the through hole 122 of the cable tray housing 1. At this time, the mounting hole 211 of the top cover 2 is exposed, and cable maintenance can be performed. When cable maintenance is not required, the second horizontal plate 42 of the second connector 4 can completely cover the mounting hole 211, thus preventing debris from falling into the cable tray.

[0042] In this embodiment, the fastener 5 can be a bolt. When the fastener 5 is a bolt with the head facing upwards, the corresponding first connecting hole 341 of the first connector 3 and the second connecting hole 421 of the second connector 4 are threaded holes that are adapted to it. When connecting, the bolt can be directly screwed into the second connecting hole 421 and the first connecting hole 341 from top to bottom in one go. During the bolt tightening process, the first groove 31 located on the outside of the bridging housing 1 can be held by hand to facilitate the screwing in of the bolt.

[0043] The trough-type cable tray provided in this embodiment achieves a detachable connection between the top cover 2 and the cable tray housing 1 through a connecting structure. The connecting structure includes a first connector 3 penetrating a through-hole 122 in the side wall of the cable tray housing 1 and a second connector 4 located above the top cover 2. The two are connected by fasteners 5, such as bolts. The first connector 3 is installed in the through-hole 122 in the side wall of the cable tray housing 1, while one end of the second connector 4 is engaged in the first groove 31 of the first connector 3, and the other end is connected to the first connector 3 via the fastener 5, thereby achieving a tight connection between the top cover 2 and the cable tray housing 1. When cable maintenance is required, simply remove the fastener 5 and slide out the second connector 4 to access the cable through the mounting hole. When the top cover 2 needs to be removed, unscrew the fastener 5, remove the second connector 4 and the first connector 3, and the top cover 2 can be removed.

[0044] The trough-type cable tray provided in this embodiment adopts a detachable connection structure. The first connector 3 is connected to the second connector 4 via a fastener after passing through the through hole 122. The inner bottom surface of the first trough 31 abuts against the top wall of the through hole 122. Therefore, after the first connector 3 and the second connector 4 are snapped together and fixedly connected, the cover 2 and the cable tray housing 1 can be securely connected. In use, the connection structure in this embodiment eliminates the need to slide the top cover 2 into the end of the cable tray housing 1. Instead, the top cover 2 is fixed to the cable tray housing 1 through a partial connection, simplifying the installation process. This is particularly suitable for long-distance or continuously laid cable trays, significantly improving installation efficiency.

[0045] The trough-type cable tray provided in this embodiment has a top cover 2 connected by simple fasteners 5.
