Description

Technical Field

[0001] This utility model relates to the field of cable tray technology, and in particular to a snap-fit ​​trough-type straight cable tray. Background Technology

[0002] Cable trays are an indispensable and important component of modern electrical system infrastructure. They are primarily made of metal or non-metal materials, commonly including steel, aluminum alloy, and fiberglass, to meet the needs of different application scenarios. Their structure generally includes components such as troughs, trays, and supports. The troughs hold various cables, the trays provide a stable surface for the cables, and the supports are responsible for supporting the entire cable tray system and securely installing it to the walls, ceilings, or floors of buildings. Cable trays have extremely important functions; they effectively organize and support cables, ensuring that cables are neatly arranged during installation and preventing tangling and chaos, greatly facilitating cable management and maintenance.

[0003] For example, utility model CN220358721U discloses a cable tray, including a base plate with heat dissipation holes at its upper end. A fixing seat is fixedly installed on the outer side of the base plate, with a first circular hole at its upper end. A side plate is fixedly installed on the upper end of the base plate, with a first insert plate fixedly installed at the front end of the side plate. A second circular hole is opened on the outer side of the first insert plate. A second insert plate is fixedly installed on the rear side of the side plate, with a third circular hole on its outer side. A fixing piece is fixedly installed on the upper end of the side plate. This cable tray, equipped with insert plates, allows for quick installation and disassembly, offering high practicality. A top cover allows for direct insertion into the tray, and the cover can be closed afterward. A dustproof plate at the bottom prevents dust from entering. The outer coating is made of ceramic, providing good fire resistance.

[0004] The above applications currently have the following shortcomings:

[0005] Multiple cable trays cannot be tightly connected. Utility Model Content

[0006] This utility model discloses a snap-fit ​​trough-type straight cable tray, which aims to solve the technical problem that multiple cable trays cannot be tightly connected.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A snap-fit ​​type slotted straight-through cable tray includes a frame. Mounting brackets are symmetrically fixedly connected to the sides of the upper surface of the frame. A breathable mesh extends through the lower surface of the frame. A locking mechanism is provided on the outer surface of the frame. The locking mechanism includes a locking plate and a first locking frame. The locking plate is fixedly connected to the sides of the upper surface of the frame. The first locking frame is fixedly connected to the side of the upper surface of the frame away from the locking plate. The locking plate rubs against the inner wall of the first locking frame. A limiting post is fixedly connected to the side of the locking plate away from the frame. A rotating sleeve is rotatably connected to the outer surface of the limiting post. A threaded rod is fixedly connected to the side of the rotating sleeve away from the locking plate. A threaded tube is fixedly connected to the upper surface of the frame. The threaded rod is threadedly connected to the inner wall of the threaded tube.

[0009] By setting up a frame and mounting bracket, it can be installed on the top of the wall, allowing the cable to be positioned at the top of the wall. By setting up a venting mesh, air in the inner cavity of the frame can be discharged through the holes of the venting mesh. By setting up a locking mechanism, multiple frames can be easily installed together, allowing multiple frames to be tightly connected, thereby achieving the effect of supporting cables of different lengths. By setting up a first locking frame and locking plate, when two frames are connected end to end, the locking plate can be inserted into the inner cavity of the first locking frame. By setting up a limiting post, the rotating sleeve can be limited, allowing the rotating sleeve to drive the threaded rod to generate stable rotation. By setting up a threaded tube, the threaded rod can be limited, allowing the threaded rod to rotate into the inner cavity of the threaded tube.

[0010] In a preferred embodiment, a limiting frame symmetrically extends through the outer side of the frame, a sliding rod is slidably connected to the inner cavity of the limiting frame, an extrusion plate is fixedly connected to one end of the sliding rod located in the inner cavity of the frame, an extrusion tube is fixedly connected to the side of the limiting frame away from the frame, a spring is fixedly connected to the end of the sliding rod away from the extrusion plate, and the end of the spring is fixedly connected to the inner wall of the extrusion tube.

[0011] By setting a limiting frame, the sliding rod can be limited, allowing it to slide stably within the inner cavity of the limiting frame. By setting a compression plate, the cable within the inner cavity of the frame can be limited and compressed. By setting a compression tube and a spring, the sliding rod can be compressed, allowing it to move within the inner cavity of the limiting frame, and the compression plate can compress the cable within the inner cavity of the frame.

[0012] In a preferred embodiment, an anti-slip block is fixedly connected to the end of the threaded rod away from the rotating sleeve. The locking mechanism further includes a second locking frame and a third locking frame. The second locking frame is fixedly connected to the side of the lower surface of the frame, and the third locking frame is fixedly connected to the side of the lower surface of the frame away from the second locking frame. A locking block is fixedly connected to the inner wall of the second locking frame. The locking block rubs against the inner wall of the third locking frame. A threaded ring passes through the lower surface of the locking block. A semi-circular threaded ring is fixedly connected to the inner wall of the third locking frame. A threaded post is threadedly connected to the inner cavity of the threaded ring and the semi-circular threaded ring.

[0013] By setting anti-slip blocks, operators can easily rotate the threaded rod. By setting second and third locking frames, the two frames can be tightly connected when they are joined end to end. By setting locking blocks, the tightness of the connection between the second and third locking frames can be increased. By setting threaded rings and semi-circular threaded rings, the threaded column can be limited, allowing it to extend into the inner cavity of the threaded ring and semi-circular threaded ring when rotating, thus ensuring a tight connection between the second and third locking frames.

[0014] As can be seen from the above, a snap-fit ​​trough-type straight cable tray has the following improvements and advantages compared with the existing technology;

[0015] Firstly, by setting up a frame and mounting bracket, it can be installed on the top of the wall, thus allowing the cable to be positioned at the top of the wall. By setting up a ventilated mesh, the air inside the frame can be discharged through the holes in the ventilated mesh.

[0016] Secondly, by setting up a locking mechanism, multiple frames can be easily installed when connected together, and multiple frames can be tightly connected together, thereby achieving the support effect for cables of different lengths. By setting up a first locking frame and a locking plate, the locking plate can be inserted into the inner cavity of the first locking frame when the two frames are connected end to end.

The locking plate 91 rubs against the inner wall of the first locking frame 95. A limiting post 92 is fixedly connected to the side of the locking plate 91 away from the frame 1. A rotating sleeve 93 is rotatably connected to the outer surface of the limiting post 92. A threaded rod 94 is fixedly connected to the side of the rotating sleeve 93 away from the locking plate 91. A threaded tube 96 is fixedly connected to the upper surface of the frame 1. The threaded rod 94 and the inner wall of the threaded tube 96 are threaded together. The cable is connected by a frame 1 and a mounting bracket 3, which can be installed on the top of the wall to position the cable. The ventilation mesh 2 allows air in the cavity of the frame 1 to be discharged through the holes of the ventilation mesh 2. The locking mechanism 9 allows multiple frames 1 to be connected together, making it easy to install multiple frames 1 and tightly connected to support cables of different lengths. The first locking frame 95 and the locking plate 91 allow the locking plate 91 to be inserted into the cavity of the first locking frame 95 when two frames 1 are connected end to end. The limiting post 92 limits the rotation sleeve 93, allowing the rotation sleeve 93 to drive the threaded rod 94 to rotate stably. The threaded tube 96 limits the threaded rod 94, allowing the threaded rod 94 to rotate into the cavity of the threaded tube 96.

[0027] Reference Figure 1 - Figure 3 In a preferred embodiment, a limiting frame 4 symmetrically extends through the outer side of the frame 1. A sliding rod 5 is slidably connected to the inner cavity of the limiting frame 4. A pressing plate 6 is fixedly connected to one end of the sliding rod 5 located in the inner cavity of the frame 1.

By setting the threaded ring 99 and the semi-circular threaded ring 912, the threaded post 910 can be limited, so that when the threaded post 910 rotates, it can extend into the inner cavity of the threaded ring 99 and the semi-circular threaded ring 912, thereby enabling the second locking frame 97 and the third locking frame 911 to be tightly connected together.

[0029] Working principle: When in use, the operator positions the mounting bracket 3 in the wall and passes the cable through the frame 1. Then, the operator inserts the positioning plate 91 of the other frame 1 into the inner cavity of the first positioning frame 95 and rotates the threaded rod 94 so that the threaded rod 94 is tightly connected to the inner cavity of the threaded tube 96. At the same time, the operator inserts the positioning block 98 into the inner cavity of the third positioning frame 911 and rotates the threaded column 910 so that the threaded column 910 rotates into the inner cavity of the threaded ring 99 and the semi-circular threaded ring 912, thereby enabling the two frames 1 to be tightly connected together.
