[0002] In modern buildings, industrial facilities, and various large-scale engineering projects, cable trays are key components that bear and protect cables, wires, and other lines. The stability and reliability of their installation are of paramount importance. As the basic structure supporting the cable trays, the performance of the cable tray supports directly affects the operation and service life of the entire cable tray system.

[0003] With the continuous development of the construction and industrial sectors, more stringent and diversified requirements have been placed on cable tray supports. On the one hand, building spaces are becoming increasingly compact, especially in situations where space is limited, such as renovations of old buildings, high-rise buildings, and data centers. This requires cable tray supports to occupy less space to accommodate the needs of dense cabling. On the other hand, the specifications and dimensions of cable trays vary greatly in different projects. Considering the possibility of future cable tray replacements and expansions, cable tray supports need to have good versatility and adaptability, be compatible with various specifications of cable trays, and reduce the cost and construction difficulty of support replacement due to changes in cable tray specifications. Utility Model Content

[0004] In view of this, the purpose of this utility model is to propose a lightweight cable tray support using a molding process to solve the problem of poor versatility and difficulty in adapting to multiple specifications of cable trays in traditional cable tray supports.

[0005] To achieve the above objectives, this utility model provides a lightweight cable tray support using a molding process, comprising: a base box, a top cover slidably mounted on one side of the base box, and several mounting brackets symmetrically mounted on both sides of the base box;

[0006] A limiting component is installed inside the base box and is used to accommodate the installation of cable trays of different sizes.

[0007] A drive assembly is mounted on one side of the base box and is used to drive the limit assembly to operate.

[0008] Preferably, the limiting assembly includes a limiting plate slidably installed inside the base box. A plurality of first sliding grooves are formed on one side of the limiting plate, and a plurality of second sliding grooves are formed on one side of the base box. A first adjusting arm is slidably installed in the second sliding groove, and the other end of the first adjusting arm is slidably installed in the first sliding groove. A rotating shaft is fixedly installed in the middle of the first adjusting arm. A second adjusting arm is slidably installed in the first sliding groove, and the other end of the second adjusting arm is slidably installed in the second sliding groove. The middle of the second adjusting arm is rotatably installed on the rotating shaft.

[0009] Preferably, a plurality of sliding grooves are provided on one side of the base box, and a plurality of sliders are fixedly installed on one side of the limiting plate. The sliders are slidably installed in the sliding grooves, and the sliders are provided with locking holes.

[0010] Preferably, the drive assembly includes a drive shaft mounted on one side of the base box, a handle fixedly mounted on one end of the drive shaft, a plurality of gears fixedly mounted on the drive shaft, a rack slidably mounted on one side of the base box, one side of the rack meshing with the gears, a plurality of slide plates fixedly mounted on the other side of the rack, and a lock head fixedly mounted on one side of the slide plate, the lock head engaging with the lock hole.

[0011] Preferably, a plurality of dustproof shells are fixedly installed on one side of the base box, the drive shaft passes through the dustproof shells, and the drive shaft is rotatably connected to the dustproof shells.

[0012] Preferably, a slot is provided on one side of the mounting bracket, and the top cover is slidably installed in the slot.

[0013] The beneficial effects of this utility model are:

[0014] 1. This lightweight cable tray support, manufactured using a molding process, features a limit assembly that, in conjunction with a drive assembly, allows for horizontal movement along the base box to accommodate cable trays of varying widths and heights. This ensures the cable trays are securely fixed and do not loosen due to vibration or external forces. During movement, the first and second adjusting arms, linked to the limit plate, extend from a folded state to form a stable triangular support structure via a shared pivot. This provides multi-directional support to the limit plate, converting linear motion into the rotational unfolding motion of the adjusting arms. This ensures smooth movement of the limit plate while enhancing its bending stiffness and overall stability when bearing the cable tray, preventing displacement or deformation. Precise cooperation between the sliding groove and the slider ensures guiding accuracy, and the symmetrical arrangement of multiple adjusting arms improves support balance. This allows the support to adapt to the installation requirements of cable trays of different sizes and maintain stable clamping force under various load conditions, improving its versatility and applicability while reducing inventory management complexity.

[0015] 2. This lightweight cable tray support, manufactured using a molding process, incorporates a drive assembly that converts external rotational force into horizontal displacement of the limiting components. Precise linear control of the limiting plate is achieved through gear and rack meshing, ensuring smooth sliding along a predetermined trajectory to accommodate cable trays of different sizes. The ergonomic handle rotation operation makes adjustment effortless and precise, reducing the difficulty for installers. A dustproof shell covers the drive shaft and rotating parts, preventing dust from entering the transmission mechanism and ensuring smooth operation. The sliding top cover facilitates the connection of the locking head and locking hole during adjustment and protects the internal mechanisms after adjustment. The overall structure is compact and reliable, effectively saving installation space, greatly improving the flexibility and adaptability of cable tray installation, increasing construction efficiency, and reducing overall costs.

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.

[0028] like Figures 1 to 7 As shown, the lightweight cable tray support using molding process includes: a base box 2, a top cover 3 slidably mounted on one side of the base box 2, and several mounting brackets 1 symmetrically mounted on both sides of the base box 2; a limiting component, which is installed inside the base box 2 and is used to accommodate the installation of cable trays of different sizes; and a drive component, which is installed on one side of the base box 2 and is used to drive the limiting component to operate.

[0029] First, the installer secures the mounting bracket 1 to the wall or supporting structure using bolts or other fasteners. Since the mounting bracket 1 is symmetrically distributed on both sides of the base box 2, it evenly distributes the load on the cable tray, improving the overall structural stability. The base box 2, as the core load-bearing component, is molded from high-strength, lightweight materials, ensuring structural strength while reducing overall weight, facilitating transportation and installation. When the cable tray needs to be installed, the operator can manually operate the drive assembly to convert the externally applied rotational force into the horizontal displacement of the limiting assembly. The limiting assembly is installed inside the base box 2 and, under the action of the drive assembly, can move horizontally along the base box 2 to accommodate cable trays of different widths or heights, ensuring the cable tray is firmly fixed and will not loosen due to vibration or external forces. The top cover 3 is slidably connected to the base box 2 via a guide groove, allowing it to be easily pushed open during installation or maintenance, providing convenient operating space. After installation, closing the top cover 3 effectively prevents dust, moisture, or other external contaminants from entering. The molded process of this bracket not only reduces production costs but also ensures the dimensional accuracy and consistency of each component, making the installation process more convenient and efficient. Meanwhile, the lightweight design reduces the load on the support structure, making it particularly suitable for space-constrained or load-bearing environments. The adjustable limit components allow the bracket to be compatible with various cable tray sizes, improving versatility and applicability, and reducing inventory management complexity. The optimized drive components make adjustment effortless and precise, reducing the difficulty of installation. The overall structure is compact and occupies little space, making it suitable for dense cabling environments. Its modular design facilitates mass production and rapid installation, significantly improving construction efficiency and reducing overall costs. This bracket ensures stable cable tray installation while offering multiple advantages such as lightweight, adaptability, protection, and economy, meeting the high requirements of modern buildings and industrial facilities for cable tray support systems.

[0030] like Figure 4 , Figure 5 , Figure 6 As shown, the drive assembly includes a drive shaft 12 mounted on one side of the base box 2, a handle 9 fixedly mounted on one end of the drive shaft 12, several gears 13 fixedly mounted on the drive shaft 12, a rack 14 slidably mounted on one side of the base box 2, one side of the rack 14 meshing with the gears 13, several slide plates 15 fixedly mounted on the other side of the rack 14, a lock head 16 fixedly mounted on one side of the slide plate 15, and the lock head 16 engaging with the lock hole 18; several dust covers 10 fixedly mounted on one side of the base box 2, the drive shaft 12 passing through the dust covers 10, and the drive shaft 12 rotatably connected to the dust covers 10; a slot 20 is provided on one side of the mounting bracket 1, and the top cover 3 is slidably mounted in the slot 20;

[0031] When the position of the limiting plate 4 needs to be adjusted, the operator first selects the lock head 16 corresponding to the target limiting plate 4 according to the requirements, pushes the slide plate 15 to insert the lock head 16 into the locking hole 18 of the slider 17 on the limiting plate 4 to complete the connection. At this time, rotating the handle 9 drives the drive shaft 12 to rotate, and the gear 13 fixedly installed on the drive shaft 12 rotates synchronously. Through the transmission action of the rack 14 meshing with the gear 13, the rotational motion is converted into the linear motion of the rack 14. The rack 14 drives the slide plate 15 and the lock head 16 fixed on its side to move synchronously. Since the lock head 16 is locked with the limiting plate 4 through the locking hole 18, the limiting plate 4 is driven to slide smoothly along the sliding groove 11 to achieve position adjustment. The dust cover 10 is fixedly installed on the bottom box 2. The rotating part of the drive shaft 12 is enclosed on one side, which not only ensures the rotational connection between the drive shaft 12 and the base box 2, but also effectively prevents dust from entering the transmission mechanism and affecting the smoothness of operation. The top cover 3 achieves the opening and closing function through the sliding cooperation between the slot 20 and the mounting bracket 1. During the adjustment process, the top cover 3 can be opened to facilitate the docking of the lock head 16 and the lock hole 18. After the adjustment is completed, the top cover 3 can be closed to protect the internal mechanism. The drive assembly achieves precise linear control of the limit plate 4 through the meshing transmission of the gear 13 and the rack 14. The rotation operation of the handle 9 is ergonomic, making the adjustment process labor-saving and precise, greatly improving the flexibility and adaptability of the cable tray installation. At the same time, the overall structure is compact and reliable, effectively saving installation space.

[0032] like Figure 2 , Figure 3 , Figure 7 As shown, the limiting assembly includes a limiting plate 4 slidably installed inside the bottom box 2. A plurality of first sliding grooves 7 are provided on one side of the limiting plate 4, and a plurality of second sliding grooves 19 are provided on one side of the bottom box 2. A first adjusting arm 5 is slidably installed in the second sliding groove 19, and the other end of the first adjusting arm 5 is slidably installed in the first sliding groove 7. A rotating shaft 8 is fixedly installed in the middle of the first adjusting arm 5. A second adjusting arm 6 is slidably installed in the first sliding groove 7, and the other end of the second adjusting arm 6 is slidably installed in the second sliding groove 19. The middle of the second adjusting arm 6 is rotatably installed on the rotating shaft 8. A plurality of sliding grooves 11 are provided on one side of the bottom box 2, and a plurality of sliders 17 are fixedly installed on one side of the limiting plate 4. The sliders 17 are slidably installed in the sliding grooves 11, and a locking hole 18 is provided on the sliders 17.

[0033] When the drive assembly pushes the limiting plate 4 to move inside the base box 2, the slider 17 fixed on the limiting plate 4 slides smoothly along the sliding groove 11 of the base box 2, ensuring that the limiting plate 4 moves linearly along a predetermined trajectory. At the same time, the first adjusting arm 5 and the second adjusting arm 6, which are linked to the limiting plate 4, begin to work together. One end of the first adjusting arm 5 slides in the second sliding groove 19 of the base box 2, and the other end slides in the first sliding groove 7 of the limiting plate 4. Similarly, one end of the second adjusting arm 6 slides in the first sliding groove 7, and the other end slides in the second sliding groove 19. The two adjusting arms are linked by a shared rotating shaft 8. As the limiting plate 4 moves, the first adjusting arm 5 and the second adjusting arm 6 rotate relative to each other under the connection of the rotating shaft 8, gradually unfolding from the folded state to form a stable triangular support structure. This unfolding action not only The limiting plate 4 provides multi-directional support and can automatically adapt to different displacements through the sliding cooperation between the adjusting arm and the slide groove. During the entire movement, the unique arrangement of the first adjusting arm 5 and the second adjusting arm 6 transforms the linear movement of the limiting plate 4 into the rotational unfolding movement of the adjusting arm. This ensures the smooth movement of the limiting plate 4 and forms a stable support structure through the gradually unfolding adjusting arm, effectively enhancing the bending stiffness and overall stability of the limiting plate 4 when bearing the cable tray, and preventing the limiting plate 4 from shifting or deforming under stress. The precise cooperation between the sliding groove 11 and the slider 17 ensures the guiding accuracy of the movement of the limiting plate 4, while the symmetrical arrangement of multiple sets of adjusting arms further improves the balance of support, enabling the limiting component to adapt to the installation requirements of cable trays of different sizes and maintain a stable clamping force under various load conditions.
