Abstract
Description
Technical Field
[0001] This utility model belongs to the field of mesh cable tray technology, and in particular relates to a reinforcement structure at the bottom of a mesh cable tray. Background Technology
[0002] Mesh cable trays are typically constructed from metal wires or rods, forming a mesh structure to support cables. As an open cable support system, mesh cable trays are widely used in power, telecommunications, and construction industries, achieving cable load-bearing and ventilation / heat dissipation through their metal mesh structure. However, at corners, branches, or vertical drop points of cable tray lines (such as nodes extending from the main cable tray to lower-level equipment), structural abrupt changes and stress concentrations can easily create weak points in the overall system. Traditional drop point structures often employ simple bends, and conventional metal mesh is prone to local deformation, tearing, and even cable wear. Therefore, we propose an improved reinforcement structure for the drop points of mesh cable trays to address the aforementioned problems. Utility Model Content
[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a reinforcement structure for the lower part of the grid cable tray that can overcome or at least partially solve the above problems.
[0004] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is: a reinforcement structure at the bottom of a mesh cable tray, including a mesh cable tray body, and further including: a triangular support part, which is set on the corner side wall of the mesh cable tray body; an arc-shaped plate, which is fixedly installed on the mesh cable tray body; and a movable clamping plate, which is set on one side of the arc-shaped plate to reinforce and limit the cables at the bends of different thicknesses.
[0005] Preferably, the triangular support includes a reinforcing plate fixed to the mesh cable tray body, and two adjacent reinforcing plates are hinged together by a pin.
[0006] Preferably, a fixing strip is fixed to one side of the arc-shaped plate, and fixing holes are provided on the two fixing strips, with fastening bolts provided at the fixing holes.
[0007] Preferably, the surface of the arc-shaped plate is threaded with a screw, one end of which is rotatably connected to the clamping plate via a bearing, and the other end of the screw is fixed with a screwing block, the surface of which is provided with equally spaced limiting holes.
[0008] Preferably, a pin is inserted into the limiting hole, and a mounting block is fixed on the surface of the arc plate on one side of the screw, with an insertion hole on one side of the mounting block.
[0009] Preferably, a protective pad is fixed to one side of the clamping plate, and the surface of the protective pad has a groove.
[0010] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art: The present invention can strengthen and limit the corner by setting the triangular support part on the mesh cable tray body, thereby improving the strength of the corner structure on the mesh cable tray body. The arc plate and clamping plate set on the mesh cable tray body can not only improve the smoothness of cable pulling during cable installation and dragging, but also fix and limit the corner of the cable laid on the mesh cable tray body after installation by the cooperation of the clamping plates, preventing shaking and wear, and improving the protection effect of the cable.

[0013] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments, so that those skilled in the art can implement it based on the description.
[0014] It should be understood that terms such as “having,” “comprising,” and “including” as used herein do not exclude the presence or addition of one or more other elements or combinations thereof.
[0015] In the description of this utility model, the terms "lateral", "longitudinal", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0016] Example 1: Refer to Figures 1-4 A reinforcement structure for the lower part of a mesh cable tray includes a mesh cable tray body 1, and further includes: a triangular support part, which is disposed on the corner side wall of the mesh cable tray body 1; an arc plate 2, which is fixedly installed on the mesh cable tray body 1; and a movable clamping plate 3, which is disposed on one side of the arc plate 2 to reinforce and limit the cables at the bends of different thicknesses.
[0017] In use, this utility model features a triangular support at the corner of the mesh cable tray body 1. The stability of the triangle is utilized to support the load evenly, thereby improving the structural stability of the corner of the mesh cable tray body 1. The mesh cable tray body 1 is equipped with an arc-shaped plate 2 and an adjustable clamping plate 3. When laying cables on the mesh cable tray body 1, the arc-shaped plate 2, due to its location at the corner, provides excellent protection for the cables at the corner by guiding the flow, preventing excessive bending and damage. At the same time, the clamping plate 3 and the arc-shaped plate 2 work together to limit and fix the cables laid at the corner, preventing displacement and thus improving the overall stability of the cables.
[0018] Example 2: Refer to Figures 1-4 Similar to Embodiment 1, but further: the triangular support includes a reinforcing plate 11 fixed to the grid cable tray body 1. Two adjacent reinforcing plates 11 are hinged together by a pin 12. A fixing strip 21 is fixed to one side of the arc plate 2. Fixing holes 22 are provided on the two fixing strips 21. Fastening bolts 23 are provided at the fixing holes 22. A screw 31 is threadedly connected to the surface of the arc plate 2. One end of the screw 31 is rotatably connected to the clamping plate 3 through a bearing. A turning block 32 is fixed to the other end of the screw 31. A limiting hole 33 is provided on the surface of the turning block 32. A pin 36 is inserted into the limiting hole 33. An installation block 34 is fixed to the surface of the arc plate 2 on one side of the screw 31. An insertion hole 35 is provided on one side of the installation block 34. A protective pad 41 is fixed to one side of the clamping plate 3. A groove 42 is provided on the surface of the protective pad 41.
[0019] The reinforcing plates 11 are provided in two sets, with three plates in each set arranged in a triangle. When the corner of the grid cable tray body 1 is under stress concentration, the reinforcing plates 11 can disperse the stress and improve the stability of the structure.
[0020] During installation, the screw 31 is rotated manually by turning the screw block 32 according to the cable thickness. This causes the clamping plate 3 to move closer to the arc plate 2, which clamps and fixes the laid cable to prevent dragging and wear at bends, thus preventing cable swaying and displacement. One side of the clamping plate 3 is provided with a protective pad 41, which has a groove 42. The groove 42 is used to hold and limit the laid cable, protecting it and fixing it while also classifying it to prevent multiple cables from intertwining. After adjustment, the pin 36 is manually inserted into the limiting hole 33, with one end of the pin 36 inserted into the insertion hole 35, thereby locking and limiting the screw 31 to prevent displacement and further improving the stability of the structure.
[0021] 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 for those skilled in the art, several modifications and improvements can be made without departing from the concept of this utility model. These are all equivalent modifications and improvements made to the above embodiments based on the essential technology of this utility model, and all of these fall within the protection scope of this utility model.
