Description

Technical Field

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

[0002] Cable trays are structured cabling systems used to support and protect cables and optical fibers. They are widely used in buildings, industries, and data centers. They typically consist of supports, brackets, and installation accessories, and are mostly made of steel, aluminum alloy, or fiberglass. They are characterized by high load-bearing capacity, corrosion resistance, and other properties. According to their structure, there are trough type, tray type, ladder type, and mesh type. The trough type has good sealing properties and is suitable for sensitive cables. The ladder type has good ventilation and facilitates heat dissipation. The mesh type is lightweight and easy to install, balancing protection and breathability. Cable trays can be flexibly combined through standardized design and can be laid horizontally, vertically, or at bends to meet complex cabling needs. At the same time, they facilitate later maintenance and expansion. They are the core equipment of modern cable management. To enhance the practicality of cable trays, a mesh type cable tray is needed.

[0003] Currently available mesh cable trays mainly consist of support devices, connecting components, and protective devices. In data centers, their transparent structure facilitates cable heat dissipation and maintenance. In industrial plants, their corrosion-resistant design withstands complex environments and is suitable for high-voltage cabling. In commercial buildings, their lightweight appearance and flexible installation make them suitable for surface mounting. In communication base stations, however, the welded joints of the mesh nodes are prone to deformation due to concentrated loads, especially when laying heavy cables. To address these issues, existing technologies only use thickened profiles at the longitudinal main load-bearing wires and add reinforced weld layers at the nodes to improve welding strength. They also use intermittently placed transverse load-bearing beams to distribute local loads. However, they have not improved the quick-assembly and disassembly structure between multiple cable trays, resulting in the need to tighten fasteners one by one. In large-scale cabling scenarios, this significantly extends the construction period, increases labor costs, and fails to meet usage requirements. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a mesh-type cable tray, which aims to improve the existing technology by not improving the quick assembly and disassembly structure between multiple cable trays, which requires tightening fasteners one by one. In large-scale cabling scenarios, this will significantly extend the construction cycle and increase labor costs.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a mesh cable tray, including a support plate, with multiple U-shaped support bars fixedly connected to the bottom end of the support plate, and multiple stabilizing bars fixedly connected between the U-shaped support bars. A quick-release mechanism is provided inside each U-shaped support bar for quickly assembling and disassembling the multiple U-shaped support bars. A limiting mechanism is provided at the top center of each U-shaped support bar for clamping and fixing cables. A fixing mechanism is provided inside the support plate for installing and fixing the device. The quick-release mechanism includes an alignment component disposed between the multiple U-shaped support bars. A locking block is fixedly connected to the front and rear sides of the left side of each U-shaped support bar. A locking component is provided inside each U-shaped support bar. A spring assembly is provided at the top of the locking component. A push rod is fixedly connected to the bottom end of the locking component on the opposite side, and a handle is fixedly connected to the opposite side of the push rod.

[0006] As a further description of the above technical solution: The limiting mechanism includes a slider, an elastic component 2 is provided in the middle of the slider, a connecting column is fixedly connected to the top of the slider, and a support clamp is fixedly connected to the top of the connecting column.

[0007] As a further description of the above technical solution: The alignment component includes a slot located at the front and rear ends of the right side of the U-shaped support bar, and an insert block is slidably connected inside the slot.

[0008] As a further description of the above technical solution: The locking assembly includes a mounting plate, the outer wall of which is slidably connected to the interior of the U-shaped support strip, and two locking blocks are fixedly connected to the left and right sides of the bottom end of the mounting plate.

[0009] As a further description of the above technical solution: The spring assembly includes a limiting slide rod, the bottom end of which is fixedly connected to the top end of the mounting plate, and a spring is sleeved on the outer wall of the limiting slide rod.

[0010] As a further description of the above technical solution: The second elastic component includes a guide rod, the outer wall of which is slidably connected to the inside of the slider, and two springs are sleeved on the front and rear sides of the outer wall of the guide rod.

[0011] As a further description of the above technical solution: The fixing mechanism includes a through hole, which is opened inside the support plate. A fixing screw is slidably connected inside the through hole, and a nut is threaded to the bottom of the outer wall of the fixing screw.

[0012] As a further description of the above technical solution: The top end of the push rod is fixedly connected to the middle of the bottom end of the mounting plate, and the outer wall of the push rod is slidably connected to the inside of the U-shaped support strip.

[0013] This utility model has the following beneficial effects: 1. In this utility model, with the help of the insertion block for alignment, multiple U-shaped support bars are inserted into the slot, which drives the locking block to be inserted into the internal slots on the front and rear sides of the U-shaped support bar. The locking block is pushed up and down and drives the mounting plate to move. The mounting plate squeezes the spring on the outer wall of the limiting slide rod. Then, the spring pushes the mounting plate with elasticity, so that the locking block is locked in the upper and lower slots of the locking block. When disassembling, press the handle to drive the push rod and pull the locking block out of the slot, so as to achieve quick disassembly and improve efficiency.

[0014] 2. In this utility model, the cable is placed inside the support clamp. If different specifications of cables need to be placed, the support clamp is moved, which in turn moves the connecting column. The connecting column moves the slider on the outer wall of the guide rod, squeezing the second spring sleeved on the outer wall of the guide rod. The second spring clamps and fixes the cable under the action of elasticity, so as to realize the placement and fixation of different specifications of cables and avoid the cables from being scattered and affecting maintenance.

The movement of the support clamp 304 causes the connecting column 303 to move. The movement of the connecting column 303 causes the slider 301 to move on the outer wall of the guide rod 3021, and compresses the spring 3022 sleeved on the outer wall of the guide rod 3021. Under the action of the elastic force, the spring 3022 clamps and fixes the cable, thereby realizing the placement of different specifications of cables and fixing the cables to prevent the cables from being scattered and affecting maintenance.
