Description

Technical Field

[0001] This utility model relates to the field of aluminum alloy composite cable tray technology, and in particular to an expandable aluminum alloy composite cable tray with foldable side plates. Background Technology

[0002] Aluminum alloy composite cable trays are modular cable support systems made of aluminum alloy materials. They are mainly used for cable laying and management in the fields of power, communication, and construction, and have the advantages of being lightweight, high-strength, and corrosion-resistant.

[0003] However, most existing aluminum alloy composite cable trays cannot expand their coverage area after assembly, limiting their application range. To address this, an expandable aluminum alloy composite cable tray with foldable side panels is proposed. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an expandable aluminum alloy composite cable tray with foldable side panels.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an expandable aluminum alloy combined cable tray with foldable side plates, comprising a cable tray body, wherein two sliding columns are slidably connected through each other on opposite sides of the cable tray body, and a moving column is fixedly connected to one end of the two sliding columns on the same side, and a positioning plate is fixedly connected to the opposite end of each moving column, and two snap-fit ​​grooves are provided on one side of each positioning plate, and a rotating column is fixedly connected to the opposite side of the two positioning plates on the same side, and a side plate body is rotatably connected to each rotating column, and a moving groove is provided on the opposite side of each side plate body, with a snap-fit ​​structure in each moving groove, and a pushing structure is provided on the cable tray body;

[0006] The pushing structure includes a bidirectional threaded rod rotatably connected inside the cable tray body. One end of the bidirectional threaded rod passes through one side of the cable tray body and is fixedly connected to an adjusting disc. The rotation of the bidirectional threaded rod is controlled by rotating the adjusting disc, thereby driving the extension mechanism.

[0007] As a further description of the above technical solution:

[0008] Two limiting rods are fixedly connected to opposite sides inside the main body of the cable tray. Two push plates are slidably connected to the two limiting rods. One side of each push plate is fixedly connected to one end of the corresponding two sliding columns. When the push plate moves, the limiting rods limit the movement of the push plate, thereby improving the stability of the push plate.

[0009] As a further description of the above technical solution:

[0010] Each of the opposite threaded sections of the bidirectional threaded rod is threaded with a movable block, and a first fixed frame is fixedly connected to the opposite side of each movable block. When the bidirectional threaded rod rotates, the movable blocks drive the corresponding first fixed frames to move closer together.

[0011] As a further description of the above technical solution:

[0012] Each of the two push plates has a second fixed frame fixedly connected to one side of its opposite side. Each second fixed frame has two push rods rotatably connected inside. The other end of each push rod is rotatably connected to the interior of the corresponding first fixed frame. When the first fixed frames are close to each other, the push rods push the corresponding second fixed frames to move, causing the two second fixed frames to move away from each other.

[0013] As a further description of the above technical solution:

[0014] The snap-fit ​​structure includes a sliding rod fixedly connected inside the moving groove, and a sliding block slidably connected to the sliding rod. The sliding block is slidably connected in the corresponding moving groove, and the sliding block slides on the sliding rod to facilitate limiting the position of the sliding block.

[0015] As a further description of the above technical solution:

[0016] One side of the sliding block is fixedly connected to a toggle block and a locking post. The locking post is adapted to the corresponding locking groove. When the toggle block is pulled, the locking post can be disengaged from the locking groove through the sliding block, which facilitates the folding of the side panel body.

[0017] As a further description of the above technical solution:

[0018] A spring is fitted on the sliding rod. One end of the spring is fixedly connected to the inner top of the moving groove, and the other end is fixedly connected to one side of the sliding block. Under the elastic reset of the spring, the sliding block drives the locking pin to engage into another corresponding locking groove, which facilitates the fixing of the side plate body.

[0019] This utility model has the following beneficial effects:

[0020] 1. Compared with existing technologies, this expandable aluminum alloy composite cable tray with foldable side panels, by setting up a bidirectional threaded rod, an adjusting plate, a moving block, a first fixed frame, a push rod, and a second fixed frame, etc., rotates the adjusting plate, which drives the bidirectional threaded rod to rotate. The bidirectional threaded rod drives the corresponding moving block to move through opposite threaded sections, bringing the two moving blocks closer together. The moving block drives the corresponding push rod to move through the first fixed frame. The push rod drives the corresponding push plate to move through the second fixed frame. The push plate drives the corresponding moving column to move to both sides through the sliding column, expanding the coverage area and increasing the range of use.

[0021] 2. Compared with existing technologies, this expandable aluminum alloy composite cable tray with foldable side panels, through the setting of sliding rods, sliding blocks, actuating blocks, locking posts, and springs, allows for easy folding and fixing of the side panel body. When folding the side panel body, two workers work together to pull the actuating block, which moves the sliding block and compresses the spring. This causes the sliding block to disengage the locking post from the corresponding locking slot. Then, the side panel body is rotated 90 degrees, and the actuating block is released. Under the elastic reset of the spring, the sliding block moves the locking post into another corresponding locking slot, facilitating the folding and fixing of the side panel body.

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] Reference Figures 1 to 10 This utility model provides an expandable aluminum alloy combined cable tray with foldable side panels: It includes a cable tray body 1. Two sliding columns 4 are slidably connected to opposite sides of the interior of the cable tray body 1. Two limiting rods 2 are fixedly connected to opposite sides of the interior of the cable tray body 1. Two push plates 3 are slidably connected to the two limiting rods 2. One side of each push plate 3 is fixedly connected to one end of the corresponding two sliding columns 4. When the push plate 3 moves, the limiting rods 2 limit its movement, improving the stability of the push plate 3. The two sliding columns on the same side... One end of the 4 is fixedly connected to a movable column 5. Each movable column 5 is fixedly connected to a positioning plate 6 at the opposite end. Each positioning plate 6 has two snap-fit ​​grooves on one side. The snap-fit ​​grooves cooperate with the snap-fit ​​column 104 to facilitate the positioning of the side plate body 8. The two positioning plates 6 on the same side are fixedly connected to a rotating column 7 on opposite sides. Each rotating column 7 is rotatably connected to the side plate body 8. Each side plate body 8 has a movable groove at the opposite side. Each movable groove is provided with a snap-fit ​​structure 10. The cable tray body 1 is provided with a pushing structure 9.

[0036] To achieve the pushing purpose, the pushing structure 9 includes a bidirectional threaded rod 901 rotatably connected inside the cable tray body 1. One end of the bidirectional threaded rod 901 passes through one side of the cable tray body 1 and is fixedly connected to an adjusting disc 902. Moving blocks 903 are threadedly connected to opposite threaded sections of the bidirectional threaded rod 901. A first fixing frame 904 is fixedly connected to the opposite side of each moving block 903. A second fixing frame 906 is fixedly connected to the opposite side of each of the two pushing plates 3. Two pushing rods 905 are rotatably connected inside each second fixing frame 906. The other end of each is rotatably connected to the interior of the corresponding first fixed frame 904. Rotating the adjustment plate 902 causes the bidirectional threaded rod 901 to rotate. The bidirectional threaded rod 901 drives the corresponding moving block 903 to move through opposite threaded sections, bringing the two moving blocks 903 closer together. The moving block 903 drives the corresponding push rod 905 to move through the first fixed frame 904. The push rod 905 pushes the corresponding push plate 3 to move through the second fixed frame 906. The push plate 3 pushes the corresponding moving column 5 to move to both sides through the sliding column 4, expanding the coverage area and increasing the range of use.

[0037] To achieve folding, the snap-fit ​​structure 10 includes a sliding rod 101 fixedly connected inside the moving groove. A sliding block 102 is slidably connected to the sliding rod 101. A spring 105 is sleeved on the sliding rod 101. One end of the spring 105 is fixedly connected to the inner top of the moving groove, and the other end is fixedly connected to one side of the sliding block 102. The sliding block 102 is slidably connected in the corresponding moving groove. A toggle block 103 and a snap-fit ​​post 104 are fixedly connected to one side of the sliding block 102. The snap-fit ​​post 104 engages with the corresponding snap-fit ​​post 104. With the slots matched, when folding the side panel body 8, two workers pull the actuating block 103 together. The actuating block 103 drives the sliding block 102 to move and compresses the spring 105, so that the sliding block 102 drives the locking post 104 to disengage from the corresponding locking slot. Then, the side panel body 8 is rotated 90 degrees and the actuating block 103 is released. Under the elastic reset of the spring 105, the sliding block 102 drives the locking post 104 to engage into another corresponding locking slot, which facilitates the folding and fixing of the side panel body 8.

[0038] Working principle: Rotating the adjusting disc 902 causes the bidirectional threaded rod 901 to rotate. The bidirectional threaded rod 901 drives the corresponding moving block 903 to move through opposite threaded sections, bringing the two moving blocks 903 closer together. The moving blocks 903 drive the corresponding pushing rod 905 to move through the first fixed frame 904. The pushing rod 905 pushes the corresponding pushing plate 3 to move through the second fixed frame 906. The pushing plate 3 pushes the corresponding moving column 5 to move to both sides through the sliding column 4, expanding the coverage area and increasing the range of use. When folding the side panel body 8, two workers pull the actuating block 103 together. The actuating block 103 drives the sliding block 102 to move and compresses the spring 105, causing the sliding block 102 to drive the locking column 104 to disengage from the corresponding locking groove. Then, the side panel body 8 is rotated 90 degrees, and the actuating block 103 is released. Under the elastic reset of the spring 105, the sliding block 102 drives the locking column 104 to engage into another corresponding locking groove, facilitating the folding and fixing of the side panel body 8.
