Description

Technical Field

[0001] This invention relates to the field of cable trays, and in particular to a modular and scalable cable tray. Background Technology

[0002] Cable trays are classified into trough type, tray type, ladder type, and mesh type structures. They are composed of supports, brackets, and installation accessories. Cable trays can be installed independently in buildings or attached to various building (structure) and pipe gallery supports. In use, they are divided into sections, and sensors can be installed in each section to form a modular design. Connecting frames are also installed on the side walls of the cable trays, and expansion can be carried out on the connecting frames (to install small supports).

[0003] Existing modular cable trays with expandable sidewalls are closed at the bottom, which provides good support for cables. However, due to maintenance and heat dissipation issues, only one layer of cables is usually installed inside the cable tray (if there are two layers, the lower layer is difficult to maintain due to obstruction from the upper layer and the closed bottom of the cable tray). This results in low horizontal space utilization of the cable tray. When multiple cables need to be arranged, the cable tray requires a larger width in the horizontal direction. In some narrow places, insufficient space will restrict its installation. Summary of the Invention

[0004] In view of the fact that the cable trays in the above or existing technologies only have one layer of cables, when multiple cables need to be arranged, the cable trays need to be wide in the horizontal direction.

[0009] As a preferred embodiment of the modular and expandable cable tray of the present invention, the moving mechanism includes an opening disposed on a flip plate, and two closing plates are disposed inside the opening. The upper end face of the closing plate, the upper end face of the bearing plate, and the upper end face of the flip plate are flush. Two guide blocks are fixedly connected to the closing plate. Two pairs of vertical grooves that cooperate with the guide blocks are provided on the left and right inner sidewalls of the opening. A first horizontal groove is connected to the vertical groove.

[0010] As a preferred embodiment of the modular and expandable cable tray of the present invention, wherein: the flip plate is provided with an elastic element for resetting the closed plate; the elastic element includes a plurality of T-shaped receiving grooves disposed on the flip plate, a T-shaped lifting plate is slidably connected in the receiving grooves, a transition plate is fixedly connected on the lifting plate, a drive shaft is rotatably connected on the transition plate, a roller is fixedly connected on the drive shaft, the upper end of the roller abuts against the bottom of the closed plate, and the lifting plate is elastically connected to the inner wall of the receiving groove through a second spring.

[0011] As a preferred embodiment of the modular and expandable cable tray of the present invention, the anti-loosening mechanism includes a mounting cavity disposed on a bearing plate, the mounting cavity having a plurality of through holes, and hooks that cooperate with the cable body are slidably connected in the plurality of through holes.

[0012] As a preferred embodiment of the modular and expandable cable tray of the present invention, wherein: an elastic friction pad is fixedly connected to the inner wall of the hook, and the hook is provided with a bending part, the curvature of the bending part being less than 120°.

[0013] As a preferred embodiment of the modular and expandable cable tray of the present invention, wherein: the mounting cavity is provided with a transmission component that provides power for the hook to descend; the transmission component includes an L-shaped sliding plate slidably connected in the mounting cavity, the horizontal edge of the L-shaped sliding plate being misaligned with the hook, the L-shaped plate being provided with a second horizontal groove, the second horizontal groove being connected to an inclined groove, the hook being fixedly connected with a guide rod that cooperates with the inclined groove and the second horizontal groove, the L-shaped sliding plate being elastically connected to the inner wall of the mounting cavity through a third spring, a rigid rope being fixedly connected to the lifting plate near the bearing plate, both the bearing plate and the flipping plate being provided with wire openings, the rigid rope passing through the guide openings and being fixedly connected to the L-shaped sliding plate.

[0015] The advantages of the modular and scalable cable tray of the present invention:

[0016] 1. By setting up partitions, the cable body is set up in two layers, so when laying multiple cable bodies, fewer cable bodies are needed in a single layer, thus requiring less width in the horizontal direction. This allows for laying in narrow lower areas and has a wider range of applications.

[0017] 2. By setting up a heat dissipation mechanism and utilizing multiple Z-shaped and L-shaped openings, the heat dissipation effect of the partition can be ensured while preventing dust inside the cable tray body, thus avoiding high internal temperature of the cable tray body and ensuring heat dissipation effect after layering.

[0018] 3. The lower part of the cable tray body can be opened by the designer through the opening and moving mechanism, which facilitates the maintenance of the lower cable body after layering. It is also set to fully open and partially open, and the support surface of different sections of the cable body is different, so as to avoid the cable body from falling and affecting the stability of the connection between the cable body and the electrical appliance.

[0019] 4. By setting an anti-loosening mechanism, during the flipping of the flip plate and the movement of the closing plate, that is, when the lower cable body lacks support, the elastic friction pad can automatically squeeze the cable body to prevent the cable body from falling, and further ensure the stability of the connection between the cable body and the electrical appliance.

[0031] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0032] Example 1, referring to Figures 1-9This is the first embodiment of the present invention. This embodiment provides a modular and expandable cable tray that can divide the main body 1 of the cable tray into two layers, saving space and facilitating the maintenance of both layers of cable bodies 2, while ensuring the heat dissipation effect of the cable bodies 2. It includes a cable tray main body 1, which has multiple cable bodies 2 inside, and a partition 3 inside, which divides the multiple cable bodies 2 into upper and lower layers; a heat dissipation mechanism, which is set inside the cable tray main body 1 to enhance air circulation and prevent the multiple cable bodies 2 from overheating; an opening mechanism, which is installed at the lower end of the cable tray main body 1 and flips downward to open the lower end of the cable tray main body 1 for easy maintenance; a moving mechanism, which is set on the opening mechanism and slides back and forth to open the lower part of the cable tray main body 1; and an anti-loosening mechanism, which is set on the cable tray main body 1 and cooperates with the moving mechanism to prevent the cable bodies 2 from falling.

[0033] Specifically, the lower end of the cable tray body 1 is open, and the partition 3 divides the cable tray body 1 into upper and lower parts. A cover plate is also installed at the upper end of the cable tray body 1 to prevent dust from entering. This is mainly for the cable body 2 with low heat generation. For the cable body 2 with high heat generation, there are U-shaped cable trays and mesh cable trays. This is a closed cable tray, which has a better protection effect. At the same time, when laying, it is necessary to ensure that the cross-sectional area of ​​the cable body 2 laid in the upper and lower parts of the partition 3 does not exceed 40% of the cross-sectional area of ​​the upper and lower parts to ensure compliance with industry standards. This is existing technology and will not be elaborated here.

[0034] Furthermore, the heat dissipation mechanism includes multiple pairs of Z-shaped openings 41 disposed on the cable tray body 1. Two Z-shaped openings 41 penetrate the cable tray body 1 and also penetrate the partition 3. L-shaped grooves 42 are provided on the Z-shaped openings 41, and the outer ends of the L-shaped grooves 42 penetrate the cable tray body 1. The opening mechanism includes two bearing plates 51 with screw holes fixedly connected to the cable tray body 1. Two rotating shafts are rotatably connected to the inner wall of the cable tray body 1, and a flip plate 52 is fixedly connected to each of the two rotating shafts. The plate 52 is provided with a locking member 53 to prevent the flip plate 52 from opening automatically; the locking member 53 includes a T-shaped groove 531 provided on the support plate 51, a T-shaped block 532 slidably connected in the T-shaped groove 531, the T-shaped block 532 being elastically connected to the inner wall of the T-shaped groove 531 by a first spring 533, the cable tray body 1 is provided with a slot 534 that cooperates with the T-shaped block 532, a lever 535 is fixedly connected to the T-shaped block 532, and a guide port that cooperates with the lever 535 is provided on the slot 534.

[0035] Among them, multiple pairs of Z-shaped openings 41 at the top and bottom all penetrate the partition 3, the partition 3 is penetrated twice, and the multiple pairs of Z-shaped openings 41 at the top and bottom are not connected, thereby ensuring the ventilation inside the partition 3, reducing the heat accumulation of the partition 3, and reducing the heat accumulation of the cable body 2. Here, the L-shaped groove 42 is connected to the Z-shaped opening 41, and air can be introduced or exhausted from the left and right ends, further enhancing the heat dissipation effect. The setting of the inclined surface 536 on the T-shaped block 532 here allows the T-shaped block 532 to move into the T-shaped groove 531 without moving the lever 535 when the flip plate 52 is deflected upward.

[0036] Preferably, the moving mechanism includes an opening on the flip plate 52, with two closing plates 61 inside the opening. The upper surfaces of the closing plates 61, the upper surfaces of the bearing plates 51, and the upper surfaces of the flip plate 52 are flush. Two guide blocks 62 are fixedly connected to the closing plates 61. Two pairs of vertical grooves 63 that cooperate with the guide blocks 62 are provided on the left and right inner sidewalls of the opening. A first horizontal groove 64 is connected to the vertical grooves 63. The flip plate 52 is provided with an elastic element 65 for resetting the closing plates 61. The elastic element 65 includes a plurality of T-shaped receiving grooves 651 on the flip plate 52. A T-shaped lifting plate 652 is slidably connected in the receiving grooves 651. A transition plate 653 is fixedly connected to the lifting plate 652. A drive shaft is rotatably connected to the transition plate 653. A roller 654 is fixedly connected to the drive shaft. The upper end of the roller 654 abuts against the bottom of the closing plate 61. The lifting plate 652 is elastically connected to the inner wall of the receiving groove 651 by a second spring 655.

[0037] It should be noted that the upper surface of the top end, the upper surface of the bearing plate 51, and the upper surface of the flip plate 52 are flush to avoid a height difference between the front and rear ends of the cable body 2, which could cause a slight drop. The flip plate 52 is also provided with an inner groove so that the adapter plate 653 can enter the inner groove, making the bottom of the flip plate 52 flush with the bottom of the adapter plate 653, preventing the adapter plate 653 from protruding and increasing the overall aesthetics.

[0038] In use, the flip plate 52 is first closed. At this time, a layer of cable body 2 is laid on the partition plate 3. Another layer of cable body 2 is laid on the flip plate 52, the bearing plate 51, and the closing plate 61, thus realizing the double-layer laying of the cable body 2. In use, the gas enters from the Z-shaped port 41 and then exits through the other end of the Z-shaped port 41. At the same time, the L-shaped groove 42 can also be used for air intake and exhaust, increasing the exhaust or intake effect and enhancing the heat dissipation effect. It is worth noting that the heat dissipation of the cable body 2 is relatively small, so there is no need to set too much heat dissipation. In the prior art, only a few holes are opened on the cable tray body 1. Here, holes are also set on the cable tray body 1 to further enhance heat dissipation and ensure the heat dissipation effect.

[0039] When it is necessary to inspect the cable body 2, the cable body 2 on the partition 3 can be inspected by simply opening the upper cover. When it is necessary to inspect the lower layer of cable body 2, there are two situations.

[0040] In the first scenario, the cable body 2 is being inspected away from the joint (i.e., away from electrical appliances, the same below). Since both ends of the cable body 2 are in a relaxed state (mainly to accommodate thermal expansion and contraction), and the force pulling on the edge of the cable body 2 is small, minimal support is required. The lever 535 can be directly moved to disengage the T-block 532 from the slot 534. At this point, the two flip plates 52 unfold, resulting in a larger open area at the lower end of the cable tray body, facilitating quick and easy maintenance. Once maintenance is complete, pushing the flip plates 52 will allow them to unfold. 52 flips upwards, at which point the inclined surface 536 of the T-shaped block 532 engages with the cable tray body 1, allowing the T-shaped block 532 to enter the T-groove 531. The first spring 533 is compressed. When the T-shaped block 532 is aligned with the slot 534, under the action of the first spring 533, the T-shaped block 532 resets and inserts into the slot 534. It is worth noting that when installing the cable tray body 1, since the flip plate 52 can be opened, the cable tray body 1 can be fixed to the crossbeam or crossarm by using bolts to engage with the screw holes on the bearing plate 51.

[0041] In the second scenario, the inspection area is close to the joint. Directly unfolding the flip plate 52 could easily cause the cable body 2 to sag and pull on the connection. Instead, pull the handle on the sealing plate 61, causing it to tilt downwards. The guide block 62 slides within the vertical groove 63, guiding the sealing plate 61. When the guide block 62 reaches the first horizontal groove 64, the sealing plate 61 moves completely to the underside of the other sealing plate 61. Moving the sealing plate 61 prevents collisions between the two sealing plates. Because only one sealing plate 61 is moved, the lower part of the cable tray body 1 is less open. Furthermore, another sealing plate 61 provides support, thus minimizing the downward distance or even preventing any downward movement, ensuring the stability of the connection at the joint. Simultaneously, as the sealing plate 61 moves downward, it comes into contact with the roller 654, causing the roller 654 to move downward, the adapter plate 653 to move, the lifting plate 652 to move downward, and the second spring 655 to extend. Thus, when the guide block 62 is aligned with the vertical groove 63 again, the second spring 655 resets, driving the sealing plate 61 to reset. The second spring 655 here has sufficient elasticity to ensure that when the cable body 2 is pressed on the sealing plate 61, the sealing plate 61 will not automatically move downward.

[0042] In summary, by setting up the partition 3, the cable body 2 is divided into upper and lower layers, which makes it more flexible to use in small space scenarios. At the same time, after dividing the cable body 2 into upper and lower layers, it is also easier to maintain the cable body 2. During maintenance, it can also prevent the cable body 2 from falling and affecting the connection with electrical appliances. In addition, by setting up a heat dissipation mechanism, the heat dissipation effect of the cable tray body 1 is ensured, and heat accumulation is prevented from affecting the cable body 2.

[0043] Example 2, refer to Figures 1-9 This is the second embodiment of the present invention. Unlike the previous embodiment, this embodiment provides a modular and expandable cable tray anti-loosening mechanism, which solves the problem of how to further prevent the cable body 2 from pulling on the connection. It includes an anti-loosening mechanism, which includes a mounting cavity 71 set on the bearing plate 51. The mounting cavity 71 is provided with multiple through holes 72. Hooks 73 that cooperate with the cable body 2 are slidably connected in the multiple through holes 72. An elastic friction pad 74 is fixedly connected to the inner wall of the hook 73. The hook 73 is provided with a bending part with an arc of less than 120°.

[0044] Specifically, the elastic friction pad 74 is set, and the curvature of the bent part is less than 120°. When the cable body 2 needs to be removed, since the cable body 2 sheath can also undergo slight deformation, a little more force is needed to directly remove or insert the cable body 2 from the hook 73 area, which facilitates the removal or connection of the entire cable body 2.

[0045] Furthermore, the mounting cavity 71 is provided with a transmission component 75 that provides power for the descent of the hook 73; the transmission component 75 includes an L-shaped slide plate 751 slidably connected in the mounting cavity 71, the horizontal edge of the L-shaped slide plate 751 is offset from the hook 73, the L-shaped plate is provided with a second horizontal groove 752, the second horizontal groove 752 is connected with an inclined groove 753, the hook 73 is fixedly connected with a guide rod 754 that cooperates with the inclined groove 753 and the second horizontal groove 752, the L-shaped slide plate 751 is elastically connected to the inner wall of the mounting cavity 71 through a third spring, a rigid rope 755 is fixedly connected to the lifting plate 652 near the bearing plate 51, both the bearing plate 51 and the flipping plate 52 are provided with wire openings, the rigid rope 755 passes through the guide openings and is fixedly connected to the L-shaped slide plate 751; the distance between the uppermost end of the inclined groove 753 and the second horizontal groove 752 is less than the length of the vertical groove 63, and when the flipping plate 52 flips, it drives the rigid rope 755 to move a distance greater than the horizontal projection length of the inclined groove 753.

[0046] It should be noted that the distance between the uppermost end of the inclined groove 753 and the second horizontal groove 752 is less than the length of the vertical groove 63. Therefore, before the guide block 62 on the sealing plate 61 moves into the horizontal groove and before the sealing plate 61 begins to move back and forth, the hook 73 has already pressed against the cable body 2. At this time, the cable body 2 has not yet sagged, resulting in better protection.

[0047] In use, when the flip plate 52 flips and the closing plate 61 moves downward, the rigid rope 755 is pulled, causing the L-shaped slide plate 751 to move. The third spring extends, and when the L-shaped slide plate 751 moves, the guide rod 754 cooperates with the inclined groove 753, causing the guide rod 754 to move downward, driving the hook 73 to move downward, so that the elastic friction pad 74 abuts against the cable body 2. The hook 73 here also serves to separate the cable body 2. The purpose of not pressing the hook 73 against the cable body 2 in the initial position is to facilitate the pulling of the cable body 2 during installation. When the guide rod 754 moves into the second transverse groove 752, the L-shaped slide plate 751 continues to be pulled, so that the guide rod 754 and the inclined groove 753 are misaligned, preventing the guide rod 754 from moving upward automatically. When the elastic friction pad 74 presses against the cable body 2, it can limit the cable body 2, preventing the cable body 2 from falling and affecting the stability of the cable body 2 connection when the lower end of the cable tray body 1 is open or partially open.

[0048] In summary, by setting up an anti-loosening mechanism, during the movement of the flip plate 52 and the downward movement of the closing plate 61, that is, when the lower end of the cable body 2 lacks support, the cable body 2 is automatically pressed by transmission to prevent the cable body 2 from falling and affecting the stability of the connection of the cable body 2.

[0049] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
