Description

Technical Field

[0001] This utility model relates to the field of ladder-type cable tray technology, specifically a novel ladder-type cable tray. Background Technology

[0002] Cable trays are classified into various structures, including trough-type cable trays, tray-type cable trays, ladder-type cable trays, and mesh cable trays. Among them, ladder-type cable trays, also known as ladder-style cable trays, are a type of metal cable tray commonly used for cable wiring. Their cross-section is trapezoidal, resembling the structure of a ladder.

[0003] Chinese patent CN218897040U discloses a ladder-type cable tray that is easy to assemble. It has multiple telescopic plates between each pair of long plates, and a pair of width positioning components between each pair of long plates, which are composed of reinforcing rods, screws, threaded connecting grooves, cavities, positioning blocks, threaded screw rods, circular extrusion plates and inclined top blocks. With the help of springs, the distance between two adjacent long plates can be adjusted. The width positioning components are easy to assemble and disassemble. After being removed, the telescopic plates can be used to bring the two long plates closer together to the minimum distance. The entire ladder-type cable tray can then be folded, which greatly reduces the space occupied by the ladder-type cable tray and makes it much easier for workers to carry and transport it.

[0004] While the above solutions utilize telescopic plates to connect adjacent cable trays, they are limited by the fixed width of the trapezoidal cable tray itself, making it difficult to accommodate and support varying numbers of cables. Therefore, we provide a novel ladder-type cable tray to address these issues. Utility Model Content

[0005] 1) Technical problems to be solved

[0006] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a new type of ladder-type cable tray.

[0007] (ii) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: a novel ladder-type cable tray, comprising:

[0009] Two longitudinal plates are arranged symmetrically, and both longitudinal plates are I-shaped.

[0010] Multiple support components are arranged at equal intervals between two longitudinal plates to support the cables located between the two longitudinal plates.

[0011] The adjustable distance assembly includes a control box, on which a moving slot is provided. A bidirectional lead screw is rotatably connected in the moving slot. Both ends of the bidirectional lead screw are threaded to linkage blocks. The ends of the two linkage blocks away from the moving slot are fixedly connected to a longitudinal plate.

[0012] Furthermore, both ends of the longitudinal plate are provided with equally spaced mounting slots.

[0013] Furthermore, the support assembly includes a storage rod and an auxiliary support rod. The storage rod has a storage groove, one end of the auxiliary support rod is slidably connected to the storage groove, and the other end of the auxiliary support rod and one end of the storage rod are respectively fixedly connected to two longitudinal plates.

[0014] Furthermore, a T-shaped groove is provided on the auxiliary support rod, and a slider is fixedly connected in the storage groove, and the slider is slidably connected in the T-shaped groove.

[0015] Furthermore, the auxiliary support rod has a first arc-shaped groove arranged at equal intervals, and the storage rod has a second arc-shaped groove arranged at equal intervals.

[0016] Furthermore, a gap is left between the control box and the longitudinal plate, and one end of the bidirectional lead screw passes through the control box and extends to the outside of the control box.

[0017] (iii) Beneficial effects:

[0018] Compared with existing technologies, this new ladder-type cable tray has the following advantages:

[0019] I. This utility model utilizes the threaded engagement between the bidirectional lead screw of the adjustable spacing component and the linkage block. Rotating the bidirectional lead screw drives the two longitudinal plates to move closer or further apart, achieving flexible adjustment of the distance between the two plates. This allows the ladder-type cable tray to dynamically change its internal space width according to the number of cables, satisfying both the compact storage of a small number of cables and the dispersed support of a large number of cables. It breaks through the limitations of the fixed width of traditional ladder-type cable trays and significantly improves the adaptability to different wiring scenarios.

[0020] II. By setting up a support component, when the cable needs to be supported, the auxiliary support rod is pulled out from the storage groove of the storage rod, and the two form a complete rod-shaped structure. The cable is supported by the first arc groove on the auxiliary support rod and the second arc groove on the storage rod. The arc groove can reduce the contact friction between the cable and the rod body, and at the same time restrict the lateral movement of the cable, making the cable arrangement more neat and orderly, and reducing the risk of line wear or short circuit caused by cable slippage.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] like Figure 1-3 As shown, this utility model provides a technical solution: a novel ladder-type cable tray, comprising two longitudinal plates 1, an adjustment assembly, and multiple support assemblies.

[0027] Two longitudinal plates 1 are arranged symmetrically, and both longitudinal plates 1 are I-shaped. Both ends of the longitudinal plates 1 are provided with equally spaced mounting slots 2. When assembling adjacent cable trays, it is necessary to use the mounting plates and mounting slots 2 to assemble the adjacent cable trays. This mounting plate is prior art and will not be described in detail in this application.

[0028] Multiple support components are arranged at equal intervals between two longitudinal plates 1 to support the cables located between the two longitudinal plates 1. The support components include a storage rod 3 and an auxiliary support rod 4. The storage rod 3 has a storage groove 8. One end of the auxiliary support rod 4 is slidably connected to the storage groove 8. The other end of the auxiliary support rod 4 and one end of the storage rod 3 are respectively fixedly connected to the two longitudinal plates 1.

[0029] A rod-shaped structure is formed by the storage rod 3 and the auxiliary support rod 4 to support the cable located between the two longitudinal plates 1.

[0030] The auxiliary support rod 4 has a T-slot 7, and a slider 9 is fixedly connected in the storage groove 8. The slider 9 is slidably connected in the T-slot 7. The T-slot 7 and the slider 9 form a limiting structure, which can store the auxiliary support rod 4 in the storage groove 8. The auxiliary support rod 4 and the storage rod 3 are connected by the T-slot 7 and the slider 9, and the rod-shaped structure formed by the storage rod 3 and the auxiliary support rod 4 is longitudinally limited.

[0031] The auxiliary support rod 4 has a first arc-shaped groove 5 arranged at equal intervals, and the storage rod 3 has a second arc-shaped groove 6 arranged at equal intervals. The first arc-shaped groove 5 and the second arc-shaped groove 6 support the cable between the two longitudinal plates 1, which can reduce the movement of the cable on the rod structure.

[0032] The adjustable distance assembly includes a control box 10, on which a moving groove 11 is provided. A bidirectional lead screw 12 is rotatably connected in the moving groove 11. Both ends of the bidirectional lead screw 12 are threaded to linkage blocks 13. The ends of the two linkage blocks 13 away from the moving groove 11 are fixedly connected to the longitudinal plate 1.

[0033] When adjusting the distance between the two longitudinal plates 1, the bidirectional lead screw 12 needs to be rotated, and the two linkage blocks 13 need to be moved in the moving groove 11, thereby causing the linkage blocks 13 to drive the longitudinal plates 1 to move, thus adjusting the distance between the two longitudinal plates 1 to suit different usage environments. After the adjustment is completed, the lead angle of the threaded engagement between the bidirectional lead screw 12 and the linkage block 13 is used to complete the limit of the movement of the linkage block 13.

[0034] A gap is left between the control box 10 and the longitudinal plate 1, and one end of the bidirectional lead screw 12 passes through the control box 10 and extends to the outside of the control box 10.
