Description

Technical Field

[0001] The utility model belongs to the technical field of cable trays, and particularly relates to a galvanized self-locking cable tray. Background Art

[0002] In industries such as electric power and communication, as the main support and fixing device for cables, the performance of cable trays is directly related to the safe and stable operation of the cable system.

[0003] In the design of traditional trough cable trays, the core components include a trough body and a trough cover. In traditional structures, both of them generally rely on a variety of fasteners such as hoop clamps, L-shaped fasteners, and fastening belts to achieve connection. This way of relying on external fasteners not only occupies valuable external space additionally, significantly increases the overall floor area, but also has relatively high requirements for the construction space during actual installation. Particularly prominent is that in narrow or restricted environments, due to the use limitations of fasteners and the cramped installation space, it is often difficult to firmly and smoothly fix the trough body and the trough cover tightly together, which undoubtedly brings great inconvenience and challenges to construction and exposes the significant limitations of traditional designs in terms of adaptability and flexibility.

[0004] Therefore, it is very necessary to invent a galvanized self-locking cable tray. Content of the Utility Model

[0005] To solve the above technical problems, the utility model provides a galvanized self-locking cable tray, which includes a cable tray trough body and a trough cover plate. The trough body of the cable tray trough body is buckled together with the inner shoulder of the trough cover plate through an outer shoulder, and the cover plate of the trough cover plate is located above the trough body.

[0006] Preferably, a number of mounting holes are provided on the surface of the trough body of the cable tray trough body, and there is a spacing between the mounting holes.

[0007] Preferably, the upper edge of the trough body bends inward to form a bending part, and the bending part is located above the outer shoulder of the trough body bending depression.

[0008] Preferably, the bending part abuts against and contacts the upper inner wall of the cover plate. After the cable tray trough body and the trough cover plate are buckled together, the bending part deforms inward and is in a state of storing energy.

[0009] Preferably, the trough body, the outer shoulder, and the bending part are integrally formed by stamping and bending from a metal material.

[0010] Preferably, the lower edge of the cover plate of the trough cover plate bends outward to form an arc-shaped buckling part, and the arc-shaped buckling part is located below the inner shoulder of the cover plate bending depression.

[0011] Preferably, the cover plate, the inner shoulder, and the arc-shaped buckling part are integrally formed by stamping and bending from a metal material.

[0012] Preferably, the outer shoulder is located on the inner side of the inner shoulder, and the concave areas formed by the bending of the outer shoulder and the inner shoulder allow them to mate and snap together.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] This new clip design allows for quick, self-locking installation between the cable tray trough and the trough cover, eliminating the need for additional fasteners. This greatly simplifies the installation process, significantly improves construction efficiency, and reduces the required installation space and floor space. Furthermore, the cable tray structure is stable and reliable. The close contact between the bent portion and the inner wall of the cover, coupled with the force-storing state after the clip, effectively enhances the overall structural strength, prevents loosening or falling off due to external forces, and ensures the long-term stability and safety of the cable tray.

[0022] As shown in the Figure 1 to the Figure 3 accompanying

[0023] A galvanized self-locking cable tray provided by the present utility model includes a cable tray trough body 1 and a trough cover plate 2. The trough 11 of the cable tray trough body 1 is buckled with the inner shoulder 22 of the trough cover plate 2 through the outer shoulder 12, and the cover plate 21 of the trough cover plate 2 is located above the trough 11.

[0024] Furthermore, both the cable tray trough body 1 and the trough cover plate 2 adopt a galvanized treatment process. This treatment not only significantly improves the corrosion resistance of the cable tray, extends its service life, but also effectively resists the erosion of the harsh environment on the cable tray material. At the same time, the galvanized treatment also endows the surface of the cable tray with a smooth and bright metallic luster, enhancing its overall aesthetic appearance and making it more in line with the aesthetic standards of modern industrial design.

[0025] Furthermore, a number of mounting holes 3 are carefully opened on the surface of the trough 11 of the cable tray trough body 1, and appropriate distances are maintained between these mounting holes. This design allows users to flexibly select the mounting position according to actual installation requirements, enhancing the adaptability and flexibility of the cable tray. The existence of the mounting holes also facilitates the subsequent fixing and management of cables, improving the overall stability and safety of the cable system.

[0026] Furthermore, the upper edge of the trough body 11 is cleverly bent inward to form a bent portion 13, which is located above the outer shoulder 12 of the bent depression of the trough body 11. This design not only enhances the strength of the edge of the trough body 11 but also plays a key role when the trough body 11 is buckled with the trough cover plate 2. When the two are buckled together, the bent portion 13 is in close contact with the upper inner wall of the cover plate 21 and undergoes slight deformation, entering a state of storing energy. This state of storing energy helps to enhance the overall stability of the bridge and prevent loosening or falling off due to external forces.

[0027] Furthermore, the trough body 11, the outer shoulder 12, and the bent portion 13, as well as the cover plate 21, the inner shoulder 22, and the arc buckling portion 23, all adopt the advanced metal material integral stamping and bending forming technology. This technology ensures the accuracy and consistency of each component of the cable bridge, reduces processing errors and assembly difficulties. At the same time, the integral forming also improves the overall strength and durability of the cable bridge, making it more capable of withstanding the challenges of use in various complex environments.

[0028] Furthermore, the lower edge of the cover plate 21 of the trough cover plate 2 is cleverly bent outward to form an arc buckling portion 23, which is located below the inner shoulder 22 of the bent depression of the cover plate 21. The design of the arc buckling portion 23 not only increases the contact area and friction between the cover plate 21 and the trough body 11 but also makes the two more tightly and firmly buckled. This design further improves the self-locking performance and sealing performance of the cable bridge, effectively preventing external factors such as dust and moisture from invading the interior of the cable system.

[0029] Furthermore, the outer shoulder 12 is located inside the inner shoulder 22, and the recessed areas formed by their own bending allow the other to be matched and buckled together. This innovative design makes the connection between the cable bridge trough body 1 and the trough cover plate 2 simpler, quicker, and more stable and reliable. Users only need to align the two and gently press to achieve self-locking connection without using any additional fasteners or tools. This design not only reduces the installation cost and time cost but also improves the construction efficiency and safety.

[0030] The working principle is as follows: First, the galvanized self-locking cable bridge of the present utility model consists of two main parts, namely the cable bridge trough body 1 and the trough cover plate 2. The trough body 11 of the cable bridge trough body 1 is prepared to be buckled with the inner shoulder 22 of the trough cover plate 2 through its unique outer shoulder 12 design. Before preparation for installation, both the trough body 11 and the trough cover plate 2 have undergone galvanizing treatment. This step not only enhances the corrosion resistance and service life of the cable bridge but also improves its appearance beauty.

[0031] The user then selects the appropriate mounting holes 3 on the surface of the cable tray trough 11 based on actual installation requirements. These mounting holes 3 are appropriately spaced to accommodate various installation scenarios and cable layout requirements. The placement of these mounting holes not only facilitates overall cable tray installation but also facilitates subsequent cable installation and management, thereby improving the overall stability and safety of the cable system.

[0032] Next, the cable tray enters the self-locking installation phase. The user aligns the trough cover 2 with the cable tray trough 1, so that the inner shoulder 22 of the trough cover 2 aligns with the outer shoulder 12 of the cable tray trough 1. At this point, the bend 13 on the upper edge of the trough 11 is in a standby position, ready to contact the upper inner wall of the trough cover 2.

[0033] As the trough cover 2 is gradually pressed downward, the bent portion 13 begins to make close contact with the upper inner wall of the cover 21 and slightly deforms due to the pressure, entering a force storage state. This deformation not only strengthens the connection between the trough 11 and the trough cover 2, but also enables the entire bridge structure to generate a certain resistance when subjected to external forces, preventing loosening or falling off.

[0034] At the same time, the arc buckle 23 below the tank cover 2 also starts to play a role. The design of the arc buckle 23 provides a fulcrum for the subsequent separation of the cover 21 and the tank 11, so that the two can be separated more smoothly during the contact buckle process.

[0035] Finally, as the downward pressure continues, the arc buckle 23 fits tightly against the area below the outer shoulder 12, further enhancing the cable tray's self-locking and sealing properties. When the trough cover 2 is fully snapped onto the cable tray trough 1, the recessed area between the outer shoulder 12 and the inner shoulder 22 perfectly aligns and locks together. At this point, the entire cable tray structure is stable and secure, maintaining the connection without the need for any additional fasteners or tools. Users can complete the installation process with a simple press, reducing installation costs and time while improving construction efficiency and safety.

[0036] Utilizing the technical solution described in the utility model, or those skilled in the art designing similar technical solutions inspired by the technical solution of the utility model to achieve the above-mentioned technical effects, all fall within the scope of protection of the utility model.
