Description

Technical Field

[0001] This utility model relates to the field of cable tray technology, and specifically to a cable tray with integrated line protection function. Background Technology

[0002] Cable trays are mainly used for supporting and installing cables and wires in large buildings. Existing cable trays have a simple structure, and the openings are generally set upwards. This means that when inspecting cables, it is necessary to climb up and open the top cover, which is a relatively cumbersome operation. Furthermore, when cables are pulled inside the tray, they rub against the bottom of the tray cavity, causing wear to the outer protective layer of the cables. In addition, the lack of independent positioning for the cables allows them to become tangled, affecting subsequent cable identification and replacement. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide a cable tray with integrated line protection function, which can be automatically opened and changed through a pull-down scheme, so as to directly remove the cable from the cable tray and solve the problems mentioned in the background art.

[0004] This utility model is achieved through the following technical solution: a cable tray with integrated line protection function, including a cable tray with an opening facing downwards. A cover plate is provided on the end face of the opening of the cable tray, and a protective layer is installed on the inner side of the cover plate. The protective layer is inserted into the opening of the cable tray. The protective layer has multiple screw holes, each screw hole is threaded with a stud, and a wire clamp is installed at one end of each stud. Multiple positioning rods are horizontally installed on the cover plate. Positioning holes are provided on the outer wall of the cable tray directly opposite the positioning rods. One end of each positioning rod extends through the protective layer and the positioning hole to the outside and is fitted with a limit ring. A first compression spring is sleeved on the outside of each positioning rod. One end of each first compression spring abuts against the cable tray, and the other end abuts against the limit ring. A side plate is installed on one side of the cover plate, and multiple positioning mechanisms are installed on the side plate.

[0005] As a preferred technical solution, the positioning mechanism includes a positioning post and a second compression spring. The side plate is provided with multiple shaft holes. One side of the cable tray is provided with insertion holes below the shaft holes. The positioning posts are all set in the shaft holes. One end of the positioning posts is set to abut against the outer wall of the cable tray. The other end of the multiple positioning posts is uniformly installed with a handle. The second compression spring is sleeved on the outside of the positioning posts. One end of the second compression spring is installed on the handle, and the other end is installed on the side plate.

[0006] As a preferred technical solution, the protective layer is made of plastic material.

[0007] As a preferred technical solution, a handle is installed on the outer side of the cover plate.

[0008] As a preferred technical solution, multiple fixing holes are provided at both ends of the cable tray.

[0009] As a preferred technical solution, both the cable tray and the cover plate are made of stainless steel.

[0010] As a preferred technical solution, multiple positioning rods are installed on one side of the cable tray.

[0011] The beneficial effects of this utility model are: the utility model has a simple structure, and the cover plate can be pulled down directly by the handle, so that the cover plate can be moved out of the cable tray along with the cable, which facilitates the inspection of the cable. After being moved into place, the cover plate is automatically positioned, and one side of the cover plate is not blocked by the positioning rod, so that the cable can be quickly taken out and put in on that side. The protective layer can reduce the friction of the cable when it is pulled, and the cable clamps can independently position each cable, avoiding confusion and making it easy to distinguish.

Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0019] All features disclosed in this specification, or all steps in all disclosed methods or processes, may be combined in any way, except for mutually exclusive features and / or steps.

[0020] Any feature disclosed in this specification (including any appended claims, abstract, and drawings) may be replaced by other equivalent or similar features, unless specifically stated otherwise. That is, unless specifically stated otherwise, each feature is merely one example of a series of equivalent or similar features.

[0021] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this utility model discloses a cable tray with integrated line protection function, including a cable tray 1. The opening of the cable tray 1 faces downward. A cover plate 2 is provided on the end face of the opening of the cable tray 1. A protective layer 3 is installed on the inner side of the cover plate 2. The protective layer 3 is inserted into the opening of the cable tray 1. The protective layer 3 is provided with multiple screw holes 14. Each screw hole 14 is threaded with a stud 4. A wire clamp 5 is installed at one end of each stud 4. Multiple positioning rods 7 are horizontally installed on the cover plate 2. Positioning holes are provided on the outer wall of the cable tray 1 at the positions corresponding to the positioning rods 7. One end of each positioning rod 7 extends through the protective layer 3 and the positioning hole to the outside and is equipped with a limit ring 8. A first compression spring 9 is sleeved on the outside of each positioning rod 7. One end of each first compression spring 9 is in contact with the cable tray 1, and the other end is in contact with the limit ring 8. A side plate 6 is installed on one side of the cover plate 2. Multiple positioning mechanisms are installed on the side plate 6.

[0022] In this embodiment, the positioning mechanism includes a positioning post 13 and a second compression spring 11. The side plate 6 is provided with multiple shaft holes. One side of the cable tray 1 is provided with insertion holes 12 below the shaft holes. The positioning posts 13 are all set in the shaft holes. One end of the positioning posts 13 is in contact with the outer wall surface of the cable tray 1. The other end of the multiple positioning posts 13 is uniformly installed with a handle 10. The second compression spring 11 is sleeved on the outside of the positioning posts 13. One end of the second compression spring 11 is installed on the handle 10, and the other end is installed on the side plate 6.

[0023] In this embodiment, the protective layer 3 is made of plastic material. The protective layer reduces friction with the cable, and the insulating function of the plastic material prevents conductivity.

[0024] In this embodiment, a handle is installed on the outer side of the cover plate 2. The handle makes it easy to pull down the cover plate, allowing the cable to be directly exposed and making it convenient to inspect it.

[0025] In this embodiment, multiple fixing holes are provided at both ends of the cable tray 1. Screws and bolts can be assembled in the fixing holes, and the other end of the screw can be fixed to the top of the building through a connecting flange to complete the fixing of the cable tray.

[0026] In this embodiment, both the cable tray 1 and the cover plate 2 are made of stainless steel, which avoids rusting and increases service life.

[0027] In this embodiment, multiple positioning rods 7 are arranged on one side of the cable tray 1, so that there are no positioning rods on the other side of the cover plate, so that the other side of the cover plate is unobstructed, which facilitates the cable to be installed into the cover plate from the side.

[0028] During testing or wiring, the cover plate can be pulled down directly by the handle, causing it to move downwards along the positioning hole. The movement of the cover plate simultaneously drives the side plate and the positioning post. After the cover plate moves to a certain position, the positioning post will be positioned opposite the insertion hole. The rebound of the second compression spring can push the handle, and the movement of the handle can drive the positioning post, allowing the positioning post to be inserted into the insertion hole. The insertion of the positioning post and the insertion hole can position the side plate and the cover plate, and one side of the cover plate is not blocked by the positioning rod, allowing the cable to be quickly taken out and inserted towards that side.

[0029] When the cable is pulled on the surface of the protective layer, the friction between the cable and the protective layer is reduced, thereby protecting the outer layer of the cable and greatly reducing the probability of wear. After the cable is pulled into place, it can be inserted into the clamp. The clamp can independently position each cable, avoiding confusion between cables and facilitating the identification and disassembly of cables.

[0030] After installation, pull the positioning pin outward by holding the lever. After the positioning pin moves out of the socket, the rebound of the first compression spring will pull the cover plate upward until the inner side of the cover plate contacts the opening end face of the cable tray, and the protective layer can be inserted into the opening of the cable tray.

[0031] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions conceived without inventive effort should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope defined in the claims.
