Description

Technical Field

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

[0002] Cable trays are primarily used as supporting components for cable laying in integrated cabling systems for power transmission and wired telecommunications. These components are most widely used in power supply departments, centralized power distribution systems in industrial and mining enterprises, hotels, and comprehensive office facilities, as well as in wired telecommunications. Cable trays come in various structures, including trough type, tray type, ladder type, and mesh type, and consist of supports, brackets, and installation accessories. Cable trays inside buildings can be installed independently or attached to various building and pipe rack supports. They should feature simple structure, aesthetically pleasing appearance, flexible configuration, and convenient maintenance. All parts must be galvanized. This applies to cable trays installed outdoors.

[0003] The trough-type cable trays are all U-shaped. Although these U-shaped cable trays are strong and easy to lay and assemble, they take up a lot of space during transportation. They can usually only be combined in pairs, which completely wastes the space in the middle of the tray. This results in a significant waste of space during transportation and reduces the space utilization rate of the trough-type cable trays during transportation. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by providing a combined trough-type cable tray, which solves the problem that U-shaped cable trays occupy a lot of space during transportation. They can usually only be combined in pairs, which completely wastes the space in the middle of the cable tray and reduces the space utilization rate of trough-type cable trays during transportation.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A combined trough-type cable tray includes a cable tray connecting plate. Extending plates are symmetrically arranged on both sides of the connecting plate. A first mating block is provided at one end of the outer end face of each extending plate, and a first connecting hole for inserting connecting bolts is provided at the other end of the extending plate. A connecting column is provided between two adjacent cable tray connecting plates. The connecting column has a long, rectangular structure with one outer surface serving as a bearing plane. A first mating groove, adapted to the first mating block, is provided at one end of the connecting column on the opposite side of the bearing plane and at one end of the connecting columns on both sides of the bearing plane.

[0007] As a preferred technical solution of this utility model, the first docking groove is provided with a second docking block, and the first docking block is provided with a second docking groove that is adapted to the second docking block.

[0008] By utilizing the above technical solution and the second docking block and the second docking groove, the connection strength between the cable tray connecting plate and the connecting column is improved.

[0009] As a preferred technical solution of this utility model, a weight reduction hole is provided through the middle of the connecting column.

[0010] By using the above technical solution and the weight-reducing holes, the overall weight of the trough-type cable tray is reduced, making it easier for workers to handle.

[0011] As a preferred technical solution of this utility model, a second connecting hole is provided on the connecting post on one side of the first docking groove, which communicates with the first connecting hole.

[0012] By utilizing the above technical solution and the first and second connecting holes, the tightness of the connection between the cable tray connecting plate and the connecting column is improved.

[0013] As a preferred technical solution of this utility model, the bridge connecting plate between the two extension plates is provided with a plurality of evenly distributed reinforcing ribs.

[0014] By using the above technical solution and the addition of reinforcing ribs, the overall strength of the cable tray connection plate is improved, and the overall strength and load-bearing capacity of the cable tray formed by multiple cable tray connection plates are also improved.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This invention reduces the transport space required during transportation and improves the loading and unloading efficiency of workers by disassembling the cable tray body into multiple parts. The cable tray connecting plate design avoids the complex and cumbersome assembly process caused by various different shaped plates, thus reducing the efficiency of cable tray assembly. Furthermore, the design of the cable tray connecting plate and connecting column allows workers to easily adjust the width of the cable tray as needed, greatly improving its applicability. The first connecting groove and first connecting block facilitate the guiding connection between the cable tray connecting plate and the connecting column, while the second connecting groove and second connecting block enhance the connection strength between the cable tray connecting plate and the connecting column.

[0024] Example

[0025] This utility model provides a combined trough-type cable tray, see reference. Figure 1-4As shown, the cable tray includes a cable tray connecting plate 1. Symmetrically arranged on both sides of the cable tray connecting plate 1 are integrally formed extension plates 101. One end of the outer end face of each extension plate 101 has a trapezoidal first mating block 102, and the other end of the extension plate 101 has a through-hole 104 for inserting a connecting bolt 3. A connecting post 2 is provided between two adjacent cable tray connecting plates 1. This assembly of the cable tray connecting plate 1 and the connecting post 2 facilitates the adjustment of the cable tray width by workers, greatly improving its applicability. The connecting post 2 has a long, rectangular structure. One of the outer surfaces of the connecting column 2 is a bearing plane 201. When multiple cable tray connecting plates 1 and connecting columns 2 are combined to form a cable tray base plate, the bearing plane 201 and the top end face of the cable tray connecting plate 1 are displaced to the same horizontal plane, which facilitates the laying of cables. The connecting column 2 on the opposite side of the bearing plane 201 and the connecting columns 2 on both sides of the bearing plane 201 are provided with a first docking groove 202 that is adapted to the first docking block 102. Through the setting of the first docking groove 202 and the first docking block 102, it is convenient for the staff to guide and connect the cable tray connecting plate 1 and the connecting column 2.

[0026] The connecting column 2 has a weight-reducing hole 203 through the middle. The weight of the connecting column 2 is reduced by the weight-reducing hole 203, which also reduces the overall weight of the trough-type cable tray and makes it easier for workers to handle.

[0027] Furthermore, a second docking block 204 is provided in the first docking groove 202, and a second docking groove 103 adapted to the second docking block 204 is provided in the first docking block 102. The connection strength between the cable tray connecting plate 1 and the connecting column 2 is improved by setting the second docking block 204 and the second docking groove 103.

[0028] Furthermore, a second connecting hole 205 communicating with the first connecting hole 104 is provided on the connecting post 2 on one side of the first docking groove 202. The fastness of the connection between the cable tray connecting plate 1 and the connecting post 2 is improved by setting the first connecting hole 104 and the second connecting hole 205.

[0029] Furthermore, the cable tray connecting plate 1 between the two extension plates 101 is provided with a plurality of evenly distributed reinforcing ribs 105. By setting the reinforcing ribs 105, the overall strength of the cable tray connecting plate 1 is improved, and the overall strength and load-bearing capacity of the multiple cable tray connecting plates 1 after forming a trough-type cable tray are also improved.

[0030] The working principle of this utility model is as follows:

[0031] When assembling the cable tray body, firstly, align and insert the first mating block 102 on the cable tray connecting plate 1 with the first mating groove 202 on the connecting column 2, so that the second mating block 204 in the first mating groove 202 is inserted into the second mating groove 103 of the first mating block 102 for fixation. At the same time, connect the first connecting hole 104 on the cable tray connecting plate 1 with the second connecting hole 205 on the connecting column 2. Insert the connecting bolt 3 into the connected first connecting hole 104 and second connecting hole 205 for fixation, thereby assembling to form the cable tray base plate. During the assembly of the cable tray base plate, it is necessary to ensure that the bearing plane 201 of the connecting column 2 and the top end face of the cable tray base plate are on the same horizontal plane to facilitate cable laying. The above method can be used to assemble a cable tray base plate with the required width as needed. Finally, the two cable tray connecting plates 1 are vertically inserted into the connecting columns 2 on both sides of the cable tray base plate in the above method to form the cable tray side plates, thus assembling to form a complete cable tray body. This utility model reduces the transportation space occupied during transportation and improves the loading and unloading efficiency of workers by disassembling the cable tray body into multiple parts. At the same time, this utility model only requires the cable tray connecting plate 1 to assemble the cable tray base plate and the cable tray side plate, avoiding the complicated and cumbersome assembly caused by various different shaped plates during the cable tray assembly process, which reduces the assembly efficiency of the cable tray.

[0032] In the description of this utility model, it should be noted that, unless otherwise specified or limited, the terms "connected" and "connection" should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integral connection; mechanical connection, electrical connection; direct connection, or indirect connection through an intermediary. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0033] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
