Description

Technical Field

[0001] The invention relates to the field of cable bridges, in particular to a cable bridge with isolation grooves. Background Art

[0002] The main function of the cable tray is to contain the cables inside it. Since various electrical equipment is needed in the building, the laying of cables is very necessary. If the cables are directly exposed outdoors or on the walls and ceilings, first, it is very unsightly for the decoration. Secondly, the cables themselves are easily damaged, and if people accidentally touch the cables, it is easy to cause safety problems. Therefore, in the prior art, the cables are completely placed inside the cable tray, which not only protects the cables, but also achieves a beautiful hiding effect.

[0003] At present, cable trays distribute cables in several areas in the form of isolation troughs. In the prior art, the isolation troughs are often divided in a manner perpendicular to the inner wall of the cable tray, such as a layered division method similar to a bookshelf. Although such isolation allows all cables to be observed at a glance, if the divisions between layers are not fine enough, there will still be gaps between the cables, and the cables will still have room to move. A large amount of space cannot be used, resulting in a decrease in space utilization.

[0004] To this end, we propose a cable tray with isolation troughs to solve the above problems. Summary of the invention

[0005] The object of the present invention is to provide a cable tray with isolation grooves to solve the problem raised in the above background technology that because the layers are not divided finely enough, there are still gaps between the cables, the cables still have space to move, and a large amount of space cannot be used, resulting in reduced space utilization. The technical solution of the present invention is aimed at the technical problem that the existing technical solutions are too single, and provides a solution that is significantly different from the existing technology.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] A cable tray with an isolation groove comprises an external connection frame, a sealing cover plate is installed on the front end surface of the external connection frame, a middle-layer dividing plate is installed on the inner side of the external connection frame, a bottom-layer dividing plate is installed on the side of the sealing cover plate close to the middle-layer dividing plate, the bottom-layer dividing plate is located between the middle-layer dividing plate and the sealing cover plate, the middle-layer dividing plate is located between the bottom-layer dividing plate and the external connection frame, and the middle-layer dividing plate and the bottom-layer dividing plate are both located inside the external connection frame and the sealing cover plate.

[0008] In a further embodiment, the surface of the sealing cover plate is slidably connected with two ends of the bottom partition plate by providing a sliding groove, and the left and right sides of the sealing cover plate are fixedly connected with reverse buckles that engage with the edge of the external connection frame.

[0009] In a further embodiment, a first groove is formed at equal distances on a side of the external connection frame close to the middle partition plate, and a second groove is formed on a side of the middle partition plate close to the bottom partition plate.

[0010] In a further embodiment, a rubber connecting strip is glued to the inner side of the outer connecting frame, and limiting rubber rings are equidistantly arranged on the surface of the rubber connecting strip.

[0011] In a further embodiment, triangular grooves are formed on the upper and lower sides of the outer connection frame, and triangular clips that are engaged with the triangular grooves are fixedly connected to the upper and lower sides of the middle layer partition plate.

[0012] In a further embodiment, a bolt hole penetrates through the outer wall of the outer connection frame, and the bolt hole is located between two adjacent first grooves.

[0013] In a further embodiment, a ceiling frame is attached to the outer wall of the outer connection frame, and the outer connection frame is connected to the ceiling frame from the inside by means of bolts penetrating bolt holes.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] The present application modifies the traditional cable tray from the vertical spatial division to the spatial division along the outline of the tray, so that the cables can be distributed in the direction of the outline of the inner wall of the outer connection frame when installed inside the tray. This distribution can avoid waste of space, and the distribution of the cables is gradually stacked from the outermost edge to the center of the outline, which will be more compact in space. Secondly, during the inspection and maintenance process, it can be checked from the outside to the inside. For cables with a low failure rate and more important requirements for stability, they can be arranged between the outer connection frame and the middle partition plate. The area between the middle partition plate and the bottom partition plate can be used as a more secondary stable area, and the inside of the bottom partition plate is placed with cables that may have problems and failures and have a higher damage rate. First, there will be no situation where important cables accidentally touch each other, and second, the utilization rate of the internal space can be improved. Compared with the traditional vertical division method, each time the space is divided, the cable and the outer connection frame are not closely fitted, there is excess space, the cable is unstable, and the space utilization is unreasonable.

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] See also Figure 1-5 In the present invention, a cable tray with an isolation groove includes an external connection frame 1, a sealing cover plate 3 is installed on the front end surface of the external connection frame 1, a middle-layer dividing plate 5 is installed on the inner side of the external connection frame 1, a bottom-layer dividing plate 10 is installed on the side of the sealing cover plate 3 close to the middle-layer dividing plate 5, the bottom-layer dividing plate 10 is located between the middle-layer dividing plate 5 and the sealing cover plate 3, the middle-layer dividing plate 5 is located between the bottom-layer dividing plate 10 and the external connection frame 1, and the middle-layer dividing plate 5 and the bottom-layer dividing plate 10 are both located inside the external connection frame 1 and the sealing cover plate 3.

[0026] Example 1

[0027] See also Figure 1-5 In an embodiment of the present invention, a cable tray with an isolation groove is provided, and the surface of the sealing cover plate 3 is slidably connected with the two ends of the bottom partition plate 10 by opening a sliding groove. The left and right sides of the sealing cover plate 3 are fixedly connected with reverse buckles 301 that engage with the edge of the external connection frame 1. The bottom partition plate 10 further divides the cables on the inner side of the middle partition plate 5. The cables located between the middle partition plate 5 and the bottom partition plate 10, the sealing cover plate 3 mainly seals the side or top of the external connection frame 1.

[0028] The outer connection frame 1 is provided with triangular grooves 4 at the upper and lower parts, and the middle dividing plate 5 is fixedly connected with triangular clips 6 which are mutually engaged with the triangular grooves 4 at the upper and lower parts. The middle dividing plate 5 is connected to the outer connection frame 1 through the triangular clips 6 and the triangular grooves 4, which is a very convenient and quick fixing method. Arranging the triangular grooves 4 inside the outer connection frame 1 allows the sealing cover plate 3 to hide all the internal structures at once.

[0029] Example 2

[0030] See also Figure 1-5 , which is different from Example 1, is that a first groove 2 is equidistantly provided on the side of the external connection frame 1 close to the middle partition plate 5, and a second groove 7 is provided on the side of the middle partition plate 5 close to the bottom partition plate 10. Both the first groove 2 and the second groove 7 can be used as areas for temporary storage of cables. The depression can improve the stability of the cable to prevent it from moving again after installation, and can also increase the internal space to accommodate thicker cables.

[0031] The inner side of the outer connection frame 1 is glued with a rubber connection strip 8, and the surface of the rubber connection strip 8 is provided with limit rubber rings 9 at equal intervals. The rubber connection strip 8 and the limit rubber rings 9 can connect multiple cables together to play a role in straightening them.

[0032] Example 3

[0033] See also Figure 1-5 , which is different from Example 1 in that: a bolt hole 11 is passed through the outer wall of the external connection frame 1, and the bolt hole 11 is located between two adjacent first grooves 2. The bolt hole 11 opened on the surface of the external connection frame 1 is mainly used for passing bolts, so that the external connection frame 1 can be fixed to the wall.

[0034] The outer wall of the external connection frame 1 is attached with a ceiling frame 12, and the external connection frame 1 is connected to the ceiling frame 12 from the inside by bolts passing through bolt holes 11. The ceiling frame 12 is mainly used for installing the ceiling. The external connection frame 1 is fixed in a lifting manner through the ceiling frame 12 and penetrated by bolts.

[0035] The working principle of the present invention is:

[0036] First, install the external connection frame 1 to the wall through bolts. The bolts need to pass through the bolt holes 11 from the inside of the external connection frame 1 and be connected to the wall. If it cannot be installed on the side of the wall and can only be installed on the ceiling, the bolt holes 11 of the external connection frame 1 need to be facing downward and installed through the ceiling frame 12. The bolts still pass through the bolt holes 11 from the inside of the external connection frame 1 and are connected to the ceiling frame 12. The top of the ceiling frame 12 is connected to the ceiling position through bolts. After installing the external connection frame 1, before installing the middle-layer dividing plate 5, the cables need to be laid first. Each cable needs to be inserted into the inside of the limiting rubber ring 9, and then the middle-layer dividing plate 5 is placed into the inside of the external connection frame 1. The triangular clamping strips 6 on the upper and lower sides are engaged with the triangular grooves 4. The space between the middle-layer dividing plate 5 and the external connection frame 1 can just accommodate a single row of cables, and each cable constrained by the rubber connecting strip 8 and the limiting rubber ring 9 can enter the inside of the first groove 2;

[0037] This arrangement of the cables along the inner edge of the external connection frame 1 can improve the utilization of space. Secondly, the outer sheath of the cables is close to the inner side of the external connection frame 1, which can improve the heat dissipation effect of the cables.

[0038] At this time, the sealing cover plate 3 can be covered, and the bottom layer dividing plate 10 can be inserted into the inner side of the upper sealing cover plate 3. The specific installation method is to insert the bottom layer dividing plate 10 from the side of the upper sealing cover plate 3, so that the cables placed on the inner side of the middle layer dividing plate 5 can be layered again. The middle layer dividing plate 5 and the sealing cover plate 3 can be set to a continuous type or a single type. When only a single middle layer dividing plate 5 is set, it can slide over a long distance, so that multiple cables can be combed. When sliding, part of the cables are located on the inner side of the middle layer dividing plate 5, and the cables covered by the middle layer dividing plate 5 or located on the back of the middle layer dividing plate 5 are another layer. Similarly, the bottom layer dividing plate 10 can also slide, and part of the cables separated are located on the inner side of the bottom layer dividing plate 10, and another part of the cables separated are located on the back of the bottom layer dividing plate 10.

[0039] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention.
