Description

Technical Field

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

[0002] A cable tray is a metal or non-metal structural system used to support, protect, and orderly lay cables and wires.

[0003] Existing cable trays are generally made of metal. During use, the trays are fixed to predetermined locations within the building, and then the cables are laid on them. However, because the trays are made of metal, and typically have ventilation slots on their side walls, open flames and high temperatures can damage the cables inside during a fire, resulting in poor protection. Furthermore, the top covers of existing cable trays are usually fixed with bolts or rivets, making installation and removal cumbersome. Therefore, we propose a flame-retardant and heat-insulating trough-type cable tray. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned shortcomings in the existing technology by proposing a flame-retardant and heat-insulating trough-type cable tray.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a flame-retardant and heat-insulating trough-type cable tray is designed, including a base plate, side plates are vertically installed on both sides of the top of the base plate, and a top cover is provided on the top of the base plate, with the bottom sides of the top cover stacked on top of the side plates.

[0006] The top cover has a first elastic connecting plate vertically installed on both sides of the bottom. When the top cover is stacked on top of the side plate, the first elastic connecting plate extends to one side of the side plate. A strip-shaped slot is opened on the side of the side plate. A strip-shaped block is installed on one side of each first elastic connecting plate. One side of the strip-shaped block extends into the corresponding strip-shaped slot.

[0007] Each side plate has a heat insulation layer installed on the side closest to the first elastic connecting plate, and the side of the heat insulation layer is in contact with the side of the first elastic connecting plate.

[0008] Both the base plate and the top cover have flame-retardant layers installed on their sides, and a support plate is installed on one side of each flame-retardant layer.

[0009] Preferably, the bottom of the bar-shaped card block is inclined.

[0010] Preferably, a heat insulation pad is provided on one side of the inside of the strip slot, and the edges of the heat insulation pad are fixed to the inner wall of the strip slot.

[0011] Preferably, a second elastic connecting plate is installed on the side of each side plate, each second elastic connecting plate is inclined, and each second elastic connecting plate extends to one side of the strip slot. A strip block is installed on the side of each second elastic connecting plate.

[0012] Preferably, both the first elastic connecting plate and the second elastic connecting plate have bending grooves on one side of their top surfaces.

[0013] Preferably, both the insulation layer and the insulation pad are made of aerogel felt material.

[0014] Preferably, the flame-retardant layer is made of rock wool or glass fiber.

[0015] Preferably, a male connector is installed at one end of the base plate and the side plate, and a female connector is provided at the other end of the base plate and the side plate, with adjacent male connectors extending into the corresponding female connectors.

[0016] The design scheme proposed in this utility model has the following beneficial effects in application:

[0017] 1. The elastic force of the first elastic connecting plate allows the strip-shaped card block to be inserted into the strip-shaped card slot, fixing the top cover to the side plate and completing the installation. Then, by pressing the second elastic connecting plate, the strip-shaped block can push the strip-shaped card block out of the strip-shaped card slot, thus separating the top cover from the side plate, making disassembly and assembly convenient.

[0018] 2. By installing flame-retardant layers on the top and bottom plates and heat insulation layers on the side plates, open flames and high temperatures from external fires can be effectively blocked. Furthermore, the heat insulation pads can prevent open flames and high temperatures from seeping into the cable tray through the strip slots, thus providing flame-retardant and heat-insulating protection for the cables on the cable tray and improving the protection effect.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Reference Figures 1-4 A flame-retardant and heat-insulating trough-type cable tray includes a base plate 1. The base plate 1 has side plates 10 vertically installed on both sides of its top. A top cover 6 is provided on the top of the base plate 1. The bottom sides of the top cover 6 are stacked on top of the side plates 10. The base plate 1, side plates 10 and top cover 6 can form a wiring channel. The wires are laid in the channel, which can protect the wires.

[0026] like Figure 1 and Figure 2 As shown, a male connector 7 is installed at one end of the base plate 1 and the side plate 10, and a female connector 2 is provided at the other end of the base plate 1 and the side plate 10. The adjacent male connectors 7 extend into the corresponding female connectors 2. During installation, the male connectors 7 on two adjacent cable trays can be inserted into the corresponding female connectors 2, so that the two adjacent cable trays will be connected end to end to complete the splicing.

[0027] like Figure 1 and Figure 3 As shown, the top cover 6 has a first elastic connecting plate 5 vertically installed on both sides of its bottom. When the top cover 6 is stacked on top of the side plate 10, the first elastic connecting plate 5 extends to one side of the side plate 10. A strip-shaped slot 11 is provided on the side of the side plate 10. A strip-shaped block 4 is installed on one side of each first elastic connecting plate 5. One side of the strip-shaped block 4 extends into the corresponding strip-shaped slot 11. In actual use, the elasticity of the first elastic connecting plate allows the strip-shaped block 4 to penetrate into the strip-shaped slot 11, fixing the top cover 6 and the side plate 10 together, which is convenient.

[0028] It should be noted that, as Figure 3 As shown, the bottom of the strip-shaped card block 4 is inclined, and a bending groove 13 is provided on one side of the top of the first elastic connecting plate 5. When the top cover 6 is placed on the top of the side plate 10, the bottom inclined surface of the strip-shaped card block 4 will first abut against the top of the side plate 10. Under the pressure of the side plate 10, the first elastic connecting plate 5 will bend and deform inward along the bending groove 13, so that it will not be stuck.

[0029] A heat insulation pad 12 is provided on one side of the inside of the strip-shaped card slot 11. The edges of the heat insulation pad 12 are fixed to the inner wall of the strip-shaped card slot 11. The heat insulation pad 12 is made of aerogel felt material. In actual use, the opening of the strip-shaped card slot 11 can be blocked by the heat insulation pad 12. In this way, in the event of a fire, external open flames and heat will not seep into the cable tray from the strip-shaped card slot 11.

[0030] like Figure 1 and Figure 3 As shown, each side panel 10 is equipped with a second elastic connecting plate 9. Each second elastic connecting plate 9 is inclined and extends to one side of the strip slot 11. A strip block 15 is installed on the side of each second elastic connecting plate 9. A bending groove 13 is provided on the top side of the second elastic connecting plate 9. When the top cover 6 needs to be removed, simply press the second elastic connecting plate 9. The second elastic connecting plate 9 will bend along the bending groove 13, which will drive the strip block 15 to push the strip block 4 out of the strip slot 11. Then, pull the top cover 6 upward to complete the disassembly.

[0031] It should be noted that the heat insulation pad 12 itself is a flexible and deformable material, so that when the strip block 15 pushes the strip block 4 out of the strip slot 11, the heat insulation pad 12 will not be damaged or fall out of the strip slot 11.

[0032] like Figure 1 and Figure 3 As shown, each side panel 10 has a heat insulation layer 3 installed on the side closest to the first elastic connecting plate 5. The side of the heat insulation layer 3 is in contact with the side of the first elastic connecting plate 5. The heat insulation layer 3 is made of aerogel felt material. During use, the heat insulation layer 3 can increase the heat insulation performance of the side panel 10, thus blocking the high temperature and open flame from the outside.

[0033] like Figure 4 As shown, flame-retardant layers 8 are installed on the sides of both the base plate 1 and the top cover 6. The flame-retardant layers 8 are made of rock wool or glass fiber. The flame-retardant layers 8 can prevent the base plate 1 and the top cover 6 from being ignited by external open flames.

[0034] like Figure 1 and Figure 4 As shown, a support plate 14 is installed on one side of the flame-retardant layer 8. The support plate 14 is made of stainless steel. The support plate 14 can increase the structural strength of the bottom plate 1 and the top cover 6, so that they will not be deformed due to external forces.

[0035] Specifically, in use, the operator fixes the base plate 1 in a preset position using a fixing frame, then lays the cable on top of the base plate 1, and then places the top cover 6 on top of the side plate 10. When the top cover 6 is placed on top, the first elastic connecting plates 5 on both sides of the bottom of the top cover 6 extend between the two side plates 10. With the cooperation of the strip-shaped locking block 4 and the side plate 10, the first elastic connecting plates 5 bend along the bending groove 13. Then, when the strip-shaped locking block 4 moves to the strip-shaped locking groove 11, the first elastic connecting plates 5 restore their deformation, which will drive the strip-shaped locking block 4 to move into the strip-shaped locking groove 11, fixing the first elastic connecting plate 5 and the side plate 10 together, thereby completing the installation of the top cover 6. The installation is convenient.

[0036] When a fire occurs and external flames spread to the cable tray, the heat insulation pad 12 can cover the strip slot 11 to prevent the flames and heat from being transferred into the cable tray through the strip slot 11. The heat insulation layer 3 can then isolate the heat outside the side plate 10, and the flame retardant layer 8 can provide flame retardant and heat insulation protection, thus improving the protection effect.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
