Description

Technical Field

[0001] This utility model relates to the field of cable trays, specifically a lightweight polymer cable tray. Background Technology

[0002] Cable trays are mainly used as support components for laying cables in integrated cabling systems such as power supply, power transmission, and wired power transfer. These support components are most widely used in power supply departments, industrial and mining enterprises, hotels, centralized power distribution systems in comprehensive office facilities, and wired telecommunications.

[0003] According to Chinese Patent No. CN222147068U, a lightweight polymer alloy cable tray is disclosed. This utility model realizes the on-site assembly of multiple cable tray bottom grooves, meets the support of cables of multiple lengths, improves the practicality of the equipment, and arranges and limits multiple cables inside the constructed cable tray to prevent displacement.

[0004] Regarding the aforementioned patent content, a limiting mechanism and a connecting mechanism are set up to enable the splicing of cable trays. However, during splicing, the lead screws on both sides need to be rotated to move the slider and the baffle, thereby achieving splicing. When disassembling the cable tray, the two lead screws also need to be rotated to reset the baffle and the slider before the cable tray can be disassembled. This disassembly and assembly process is quite cumbersome, thereby reducing the efficiency of disassembly and assembly of cable trays. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a lightweight polymer cable tray to solve the technical problem of poor assembly and disassembly efficiency of cable trays.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a lightweight polymer cable tray, comprising a cable tray, wherein a fixing plate is fixed to one side of the outer surface and one side of the back of the cable tray, and a slot is provided on one side of the fixing plate, and a limiting component is provided inside the fixing plate, the limiting component comprising a groove formed at the upper and lower interior of the fixing plate, an insert plate inserted into the slot, and a second spring installed on one side of the slot, one end of the second spring being connected to a push plate, and slots being formed at the top and bottom of the insert plate, a first spring being installed inside the groove, and a movable block being connected to the end of the first spring, a locking block extending into the slot being fixed on the movable block, and a pull rod extending through to the outside of the fixing plate being fixed on the movable block.

[0007] By adopting the above technical solution, the slots and inserts are designed to splice the cable trays, and the inserts can be locked and limited after the card block is inserted into the slot to prevent the inserts from moving at will.

[0008] Furthermore, a pull plate is connected to the end of the pull rod, and a pull ring is provided on the pull plate.

[0009] By adopting the above technical solution, it is convenient for staff to pull the pull plate. The movement of the pull plate will drive the pull rod to move, and the pull rod will then drive the locking block to move.

[0010] Furthermore, the cable tray is provided with a cover plate on the top, and multiple slots are provided on the outer surface and back of the cable tray.

[0011] By adopting the above technical solution, the setting of the slot effectively reduces the overall weight of the cable tray. At the same time, the slot allows the inside of the cable tray to be connected to the outside, so that the cables placed in the cable tray have sufficient ventilation space and avoid overheating that could cause fire or damage.

[0012] Furthermore, the lower interior of the cable tray is provided with multiple partitions.

[0013] By adopting the above technical solution, multiple cables can be conveniently placed in the cable fixing area separated by the spacer strip on the bottom surface of the cable tray bottom groove.

[0014] Furthermore, the upper side and lower side of the insert plate are both inclined to one side of the card block.

[0015] By adopting the above technical solution, when the insert plate is inserted into the slot, the insert plate will push the card block to move into the groove, thus avoiding the card block from obstructing the movement of the insert plate.

[0016] Furthermore, one side of the insert plate contacts the push plate, and the push plate is slidably connected to the slot.

[0017] By adopting the above technical solution, when the card block no longer limits the insertion plate, the second spring is stretched and pushes the push plate to reset. The push plate then pushes the insertion plate to move, causing the card block and the card slot to be misaligned, making it easier for workers to separate the cable tray.

[0018] Furthermore, the card block is slidably connected to the groove via a movable block.

[0019] By adopting the above technical solution, when the locking block moves into the groove, the movable block will squeeze the first spring, causing the first spring to be compressed.

[0020] Furthermore, the two insert plates are respectively installed on the other side of the outer surface and the other side of the back of the cable tray.

[0021] By adopting the above technical solution, it is convenient to splice and assemble cable trays.

[0022] Furthermore, both the cable tray and the cover plate are made of lightweight polymer alloy material.

[0023] By adopting the above technical solutions, the cable trays are made lighter, making them easier to handle.

[0024] In summary, the present invention has the following main advantages:

[0025] 1. This utility model, by setting a limiting component, allows for the insertion of a plate from one side of a cable tray into the slot of another cable tray when splicing cable trays. When the plate is inserted, it pushes a locking block into the groove, preventing the block from obstructing the plate's movement. Simultaneously, as the locking block moves into the groove, a movable block compresses a first spring. When the slot on the plate aligns with the locking block, the first spring stretches, pushing the locking block back to its original position, thus locking the plate into the slot and limiting its movement. This completes the splicing of cable trays without the need for locking mechanisms like screws; simply inserting the plate into the slot simplifies the splicing process and improves the efficiency of cable tray splicing.

[0026] 2. This utility model is equipped with a push plate and a second spring. When the insert plate is inserted into the slot, it pushes the push plate to move, and the push plate squeezes the second spring, causing the second spring to be compressed. When the cable tray is disassembled and the locking block moves out of the slot and no longer limits the insert plate, the second spring stretches and pushes the push plate to move. The push plate then pushes the insert plate to move, causing the slot and locking block on the insert plate to misalign. This makes it easier for the staff to separate the cable tray when they release the pull plate, thus improving the efficiency of disassembling and assembling the cable tray.

[0034] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0035] The embodiments of this utility model will be described below based on its overall structure.

[0036] Example 1:

[0037] A lightweight polymer cable tray, such as Figures 1-6 As shown, the cable tray includes a cable tray 1. A fixing plate 5 is fixed to one side of the outer surface and one side of the back of the cable tray 1. A slot 6 is opened on one side of the fixing plate 5, and a limiting component 7 is provided inside the fixing plate 5. A cover plate 2 is provided on the top of the cable tray 1. Multiple partitions 4 are provided in the lower part of the inside of the cable tray 1. The cable fixing area is divided by the partitions 4 in the bottom groove of the cable tray 1, which facilitates the placement of multiple cables.

[0038] See Figures 1-5 The limiting component 7 includes a groove 704 formed on the upper and lower sides of the fixed plate 5, an insert plate 701 inserted into the slot 6, and a second spring 709 installed on one side of the slot 6. One end of the second spring 709 is connected to a push plate 710. The top and bottom of the insert plate 701 are provided with slots 702. The groove 704 is equipped with a first spring 705, and the end of the first spring 705 is connected to a movable block 708. The slot 6 and the insert plate 701 are provided to splice the cable tray 1. After the locking block 703 is inserted into the slot 702, it can lock and limit the insert plate 701 to prevent the insert plate 701 from moving at will.

[0039] See Figures 2-6A locking block 703 extending into the slot 702 is fixed on the movable block 708. A pull rod 706 extending through the outside of the fixed plate 5 is also fixed on the movable block 708. A pull plate 707 is connected to the end of the pull rod 706. A pull ring is provided on the pull plate 707 so that the operator can pull the pull plate 707. The movement of the pull plate 707 will drive the pull rod 706 to move, and the pull rod 706 will then drive the locking block 703 to move. The upper side and the lower side of one side of the insert plate 701 are both inclined to one side of the locking block 703 so that when the insert plate 701 is inserted into the slot 6, the insert plate 701 will push the locking block 703 into the groove 704, so as to avoid the locking block 703 from obstructing the movement of the insert plate 701.

[0040] Specifically, one side of the insert plate 701 contacts the push plate 710, and the push plate 710 is slidably connected to the slot 6. When the locking block 703 no longer limits the insert plate 701, the second spring 709 stretches and pushes the push plate 710 to reset. The push plate 710 then pushes the insert plate 701 to move, causing the locking block 703 to be misaligned with the slot 702, making it easier for workers to separate the cable tray 1. The locking block 703 is slidably connected to the groove 704 through the movable block 708. When the locking block 703 moves into the groove 704, the movable block 708 will squeeze the first spring 705, causing the first spring 705 to be compressed. The two insert plates 701 are respectively installed on the other side of the outer surface and the other side of the back of the cable tray 1, which facilitates the splicing and assembly of the cable tray 1.

[0041] Example 2:

[0042] Based on the above embodiment 1, the following method will be adopted to make the cable tray 1 lightweight.

[0043] See Figures 1-3 Multiple slots 3 are provided on the outer surface and back of the cable tray 1. The slots 3 effectively reduce the overall weight of the cable tray 1. At the same time, the slots 3 allow the inside of the cable tray 1 to be connected to the outside, so that the cables placed in the cable tray 1 have sufficient ventilation space to avoid overheating and fire or damage. The cable tray 1 and the cover plate 2 are both made of lightweight polymer alloy material, which makes the cable tray 1 lightweight and convenient to handle.

[0044] The working principle of this utility model is as follows: First, when splicing cable trays 1, the insert plate 701 on one side of one cable tray 1 can be inserted into the slot 6 of another cable tray 1. When the insert plate 701 is inserted, it will push the locking block 703 to move into the groove 704 to avoid the locking block 703 from obstructing the movement of the insert plate 701. At the same time, when the locking block 703 moves into the groove 704, the movable block 708 will squeeze the first spring 705. When the slot 702 on the insert plate 701 is aligned with the locking block 703, the first spring 705 is stretched and pushes the locking block 703 to reset and move, so that the locking block 703 is locked into the slot 702, thereby locking and limiting the insert plate 701. In this way, the splicing of the cable tray 1 can be completed.

[0045] The cable fixing area divided by the spacer 4 in the bottom surface of the bottom groove of the cable tray 1 is convenient for placing multiple cables. The setting of the groove 3 effectively reduces the overall weight of the cable tray 1. At the same time, the groove 3 can connect the inside and outside of the cable tray 1, so that the cables placed in the cable tray 1 have enough ventilation space to avoid overheating and causing fire or damage.

[0046] When the insert plate 701 is inserted into the slot 6, it pushes the push plate 710 to move. The push plate 710 then compresses the second spring 709, causing the second spring 709 to be compressed. When disassembling the cable tray 1, the operator pulls the pull rod 706 through the pull plate 707. The movement of the pull rod 706 causes the locking block 703 to move. When the locking block 703 moves out of the slot 702 and no longer limits the insert plate 701, the second spring 709 stretches and pushes the push plate 710 to move. The push plate 710 then pushes the insert plate 701 to move, causing the slot 702 on the insert plate 701 to be misaligned with the locking block 703. Then the operator releases the pull plate 707, and the cable tray 1 can be removed.
