Description

Technical Field

[0001] This utility model relates to the field of cable tray technology, and in particular to a splicing lightweight cable tray system. Background Technology

[0002] A cable tray system is a structural system used to support and protect cables, pipes, and other equipment. It mainly consists of the cable tray body (made of metal or non-metal materials, in various shapes to support the equipment), connectors (such as connecting plates and screws to ensure overall stability and continuity), accessories (including covers, fireproof partitions, protective covers, etc. to complete the functions), and support structures (such as lifting lugs, brackets, bolts, etc. to ensure secure installation). Through the reasonable cooperation of each part, it provides a safe, stable, and flexible solution for laying cables and other equipment.

[0003] Chinese patent CN218867826U discloses a splicing cable tray, belonging to the field of cable tray technology. It includes two baffles arranged in parallel and symmetrical distribution. A pad is placed between the lower ends of the two baffles, and a cover plate is placed between their upper ends. Each baffle has an outward-facing U-shaped first clamp at its upper end and an inward-facing U-shaped second clamp at its lower end. The front side of each baffle has a connecting tenon groove for splicing, and the outer surface of the baffle has a positioning hole on one side of the connecting tenon groove. The rear end of each baffle has a tenon assembly for splicing. This design enables splicing of the cable tray, allowing for adjustments based on usage needs. It also provides shielding to prevent electromagnetic interference from the cables within the tray.

[0004] The inventors have discovered at least the following problems in the prior art:

[0005] Although the aforementioned splicing cable trays can be spliced ​​together using baffles, pads, and covers and their external structures, thus facilitating transportation, they require individual snap-fitting during splicing. Furthermore, since the baffles, pads, and covers are separate and relatively independent, they need to be produced individually during the production process, which leads to increased production costs.

[0006] In addition, the need for interconnection between baffles, pads, and covers results in a large number of connection structures, which increases the weight of the entire bridge and thus limits its load-bearing capacity.

[0007] Therefore, the aforementioned technical problems need to be solved. Utility Model Content

[0008] The purpose of this invention is to provide a modular lightweight cable tray system to solve the problems in the prior art where the modular cable trays not only have high production costs, but also increase in weight and are not lightweight enough.

[0009] To solve the above-mentioned technical problems, the basic technical solution proposed by this utility model is as follows:

[0010] A modular lightweight cable tray system includes multiple cable tray plates. Each cable tray plate has connecting uprights on both sides of its upper end. Two connecting uprights are connected by equally spaced mating uprights. Two bolts are fixedly connected to one side of each cable tray plate. Two spacers are equally spaced between the two bolts. One end of each cable tray plate is fixedly connected to a mating cross plate, and the other end is provided with a mating groove. Equally spaced protrusions are fixedly connected to both sides of the upper end of each cable tray plate.

[0011] Preferably, the spacer plate fits the gap between the connecting plate and the docking plate, and also fits the gap between multiple docking plates.

[0012] Preferably, the inner side of the docking groove is provided with a stepped insertion hole one, and the docking cross plate is provided with a stepped insertion hole two. Positioning pins are inserted into both the stepped insertion hole one and the stepped insertion hole two.

[0013] Preferably, the connecting plate has a sliding groove on the side near the docking plate and on both sides of the docking plate.

[0014] Preferably, both sides of the spacer are fixedly connected to sliders, which fit into the grooves.

[0015] Preferably, each of the connecting plates has a notch that fits the outer periphery of the screw.

[0016] Preferably, a support frame is provided below the cable tray plate, and the cable tray plate has mounting holes at the support frame.

[0017] The beneficial effects of this utility model are:

[0018] I. This utility model integrates the cable tray plate, connecting upright plate, docking upright plate, partition plate, screw, protrusion block and docking horizontal plate into one piece. Therefore, it is not necessary to produce multiple components in the production process. Only one component needs to be produced to assemble the cable tray, thereby reducing the production cost.

[0019] II. This utility model, through the mutual cooperation of the cable tray plate, connecting upright plate, docking upright plate, spacer plate, screw, protrusion block, docking horizontal plate and positioning pin, has gaps between the connecting upright plates on both sides above the cable tray plate and between the docking upright plates that are equidistantly distributed between the two connecting upright plates, which facilitates airflow. This not only facilitates heat dissipation for the cables placed in the cable tray, but also reduces the overall weight, making it lighter and more portable, and increasing the load-bearing capacity.

[0028] Please refer to the following. Figures 1 to 5 As shown, the technical solutions in the embodiments of this utility model are clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0029] It should be noted that, in the embodiments of this utility model, the directions shown in the accompanying drawings shall prevail, such as front and back. Figure 1 For the sake of accuracy, the specific details should be as follows: Figure 1 The left side is the front. Figure 1 The right side is the rear; at the same time, as Figure 2 As shown, the horizontal direction is roughly defined as left and right, and the vertical direction is defined as up and down. If a specific orientation changes, the directional indication will also change accordingly.

[0030] This utility model provides a splicing lightweight cable tray system, including multiple cable tray plates 1. Connecting upright plates 2 are provided on both sides of the upper end of the cable tray plate 1. Equally spaced docking upright plates 3 are provided between two connecting upright plates 2. Screws 5 are fixedly connected to both sides of one side of the cable tray plate 1. Equally spaced spacer plates 4 are provided between two screws 5. A docking horizontal plate 7 is fixedly connected to one end of the cable tray plate 1, and a docking groove 11 is opened at the other end. Equally spaced protrusions 6 are fixedly connected to both sides of the upper end of the cable tray plate 1.

[0031] The cable tray plate 1, connecting upright plate 2, docking upright plate 3, spacer plate 4, screw 5, protrusion block 6, and docking horizontal plate 7 constitute a component. Two such components are connected symmetrically at their upper and lower centers to form a cable tray. During connection, the spacer plate 4 in the upper component fits into the gap between the connecting upright plate 2 and the docking upright plate 3, and the screw 5 in the lower component enters the notch 21 in the upper component. The screw 5 can be positioned by bolting it. After the cable tray is formed, it can be connected end to end by the docking horizontal plate 7 and the positioning pin 8.

[0032] In a further embodiment, the spacer 4 fits the gap between the connecting upright 2 and the docking upright 3, and also fits the gap between the multiple docking uprights 3.

[0033] In this embodiment, the width of the partition plate 4 matches the gap between the connecting upright plate 3 and the gap between the connecting upright plate 3 and the connecting upright plate 2. The partition plate 4, the connecting upright plate 2, and the connecting upright plate 3 are staggered to each other, so they can be inserted. After the insertion is completed, the spacing between the upper and lower cable tray plates 1 can be controlled as needed. This can maximize the use of limited space resources and improve the space utilization rate of the cable tray.

[0034] In addition, the gaps between the connecting upright plate 2 and the docking upright plate 3, as well as between the multiple docking upright plates 3, make the two sides of the cable tray hollow, thus facilitating airflow and heat dissipation for the cables.

[0035] In a further embodiment, a stepped insertion hole 12 is provided on the inner side of the docking groove 11, and a stepped insertion hole 71 is provided on the docking cross plate 7. A positioning pin 8 is inserted into the interior of both the stepped insertion hole 12 and the stepped insertion hole 71.

[0036] In this embodiment, both stepped socket 12 and stepped socket 71 are stepped, so that the positioning pin 8 is inserted from above when plugging in, and after insertion, the positioning pin 8 is flush with the surface of the cable tray plate 1, which can avoid affecting the placement of the cable.

[0037] In a further embodiment, grooves 31 are provided on the side of the connecting plate 2 near the docking plate 3 and on both sides of the docking plate 3.

[0038] In this embodiment, the protrusion 6 creates an auxiliary combing protrusion on the inside of the cable tray, which makes it easier to comb the cables placed in the cable tray.

[0039] In a further embodiment, sliders 41 are fixedly connected to both sides of the spacer 4, and the sliders 41 fit into the grooves 31.

[0040] In this embodiment, the engagement of slider 41 and groove 31, as well as the engagement of notch 21 and screw 5, allows the upper and lower components to slide. After determining an appropriate distance, the screw 5 can be tightened with a bolt from one end to achieve positioning.

[0041] In a further embodiment, each connecting plate 2 is provided with a notch 21, which fits the periphery of the screw 5.

[0042] In this embodiment, the lengths of the groove 31 and the notch 21 are the same and are half the lengths of the connecting plate 2 and the docking plate 3, thus limiting the shortest distance between the upper and lower components.

[0043] In a further embodiment, a support frame 9 is provided below the cable tray plate 1, and the cable tray plate 1 has a mounting hole 13 at the support frame 9.

[0044] In this embodiment, the support frame 9 is a bracket for installation on the wall, with a protruding rod on top, which can support the components of the cable tray plate 1 and other structures through the mounting hole 13.

[0045] The working principle of this utility model is as follows:

[0046] When splicing is required, the two cable tray plates 1 are symmetrically positioned at their top and bottom, so that the partition plate 4 on one side of the upper cable tray plate 1 is aligned with the gaps between the multiple docking upright plates 3 on the lower cable tray plate 1 and the gaps between the docking upright plates 3 and the connecting upright plates 2. Then, it is moved down. During this process, the screw 5 will enter the notch 21 opened in the other connecting upright plate 2. After determining the distance between the upper and lower cable tray plates 1, it can be fixed with nuts. In this way, a cable tray can be spliced. When multiple cable trays need to be docked, the docking horizontal plate 7 can be inserted into the docking groove 11 of another cable tray and the docking can be completed by inserting the positioning pin 8 from the top. Since the cable tray plate 1, connecting upright plate 2, docking upright plate 3, partition plate 4, screw 5, protrusion 6 and docking horizontal plate 7 are a whole, only one component needs to be produced in the production process to splice and form a cable tray, thereby reducing production costs.

[0047] In addition, since there are gaps between the connecting uprights 2 on both sides above the cable tray plate 1 and the docking uprights 3 that are equidistantly distributed between the two connecting uprights 2, the overall weight can be shortened, making it lighter and increasing the load-bearing capacity. It also facilitates airflow, thereby facilitating heat dissipation for the cables placed in the cable tray.

[0048] The protrusion 6 allows for cable management when the cable is placed on top of the cable tray plate 1, which not only optimizes the cable placement layout but also further assists in heat dissipation.

[0049] Based on the disclosure and teachings of the above specification, those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments disclosed and described above, and some modifications and changes to this utility model should also fall within the protection scope of the claims of this utility model. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on this utility model.
