Description

Technical Field

[0001] The utility model relates to the technical field of cable bridges, in particular to a reinforced self-locking cover cable bridge. Background Art

[0002] Cable tray is an open or semi-enclosed structure for laying cables. It is widely used in the power supply system of electrical equipment and plays a role in supporting, managing and protecting cables. It can ensure that the cables are neatly and orderly arranged in the tray, which is convenient for the installation, replacement and maintenance of cables and effectively prevents the cables from being affected by the external environment. The tray is often produced separately with the base and the top cover, which can be assembled after transportation.

[0003] The existing assembly method mostly uses bolts or screws for fixing. After multiple disassembly and assembly or long-term use, the connection parts are prone to damage, which leads to a gradual decrease in the stability of the connection, and may even lead to a situation where it cannot be effectively fixed. In the prior art, there is a method of setting a buckle assembly at the connection for fixing. It is easy to install and disassemble and has strong practicality. However, it is found that because the cable tray is mostly made of alloy material with high hardness, in the production process, it is necessary to ensure the strength and durability of the buckle while considering its overall mechanical properties after being connected to the alloy frame, resulting in high processing costs and technical difficulties for the one-piece buckle. Utility Model Content

[0004] In order to solve the problems in the above-mentioned background technology, the utility model provides a reinforced self-locking cover cable tray.

[0005] The solution adopted by the utility model to solve its technical problems is: a reinforced self-locking cover cable tray, including a base and a top cover covering the base, the top of both sides of the base are provided with a first sliding connection part formed by stamping, and the bottom of both sides of the top cover are provided with a second sliding connection part formed by stamping and used to slide into the first sliding connection part to form a fixed part, and the first sliding connection part is adapted to the second sliding connection part.

[0006] By adopting the above technical scheme, when producing and assembling the base and the top cover, the first sliding connection part and the second sliding connection part are respectively stamped out at the assembly connection of the base and the top cover, and the second sliding connection part is slidably snapped into the first sliding connection part for connection and fixation. It is convenient for disassembly and assembly, and the sliding snap-fit ​​structure can also avoid damage to the connection between the base and the top cover after multiple disassembly and assembly, thereby extending the service life of the frame.

[0007] Furthermore, the cross-sections of the first sliding portion and the second sliding portion are both semicircular with the openings facing outwards.

[0008] By adopting the above technical solution, the first sliding connection part and the second sliding connection part are two arc-shaped structures that slide into and engage with each other, presenting a semi-circular arc. They can disperse the force, evenly distribute the tension, reduce the stress in the local area, and centrally provide good compressive and bending resistance, increasing the structural strength and stability of the connection of the frame body.

[0009] Furthermore, the opening width of the second sliding connection part is greater than that of the first sliding connection part, and the second sliding connection part is slidably clamped into the first sliding connection part through interference fit.

[0010] By adopting the above technical solution, the opening width of the second sliding connection part is slightly greater than that of the first sliding connection part, and the material of the frame body has certain elasticity and toughness. The second sliding connection part can be embedded into the first sliding connection part by means of interference fit, ensuring the firm connection between the base and the top cover and avoiding loosening.

[0011] Furthermore, an arc-shaped groove formed by folding is provided between the top cover and the second sliding connection part. An arc-shaped flanging for clamping into the arc-shaped groove is formed by radially folding outwards along the top of the first sliding connection part, and the arc-shaped groove is adapted to the arc-shaped flanging.

[0012] By adopting the above technical solution, while sliding the second sliding connection part into the first sliding connection part, the arc-shaped flanging is also slid into the arc-shaped groove to form a double locking mechanism, making the connection between the top cover and the base more stable. And the arc-shaped flanging can strengthen the structural strength of the base and improve the overall strength performance of the first sliding connection part and the frame body.

[0013] Furthermore, anti-slip lines are provided on the contact end faces of the first sliding connection part and the second sliding connection part.

[0014] By adopting the above technical solution, the friction force between the contact surfaces of the first sliding connection part and the second sliding connection part can be enhanced.

[0015] Furthermore, a reinforcing rib is provided between the first sliding connection part and the top of the base.

[0016] By adopting the above technical solution, the reinforcing rib can disperse the stress, strengthen the structural strength and stiffness of the first sliding connection part, avoid the deformation of the arc groove of the first sliding connection part caused by stress, and extend the service life.

[0017] To sum up, the beneficial effects of the present utility model are as follows: Through the connection structure integrally manufactured between the top cover and the base, the second sliding connection part is slidably connected to the first sliding connection part through interference fit, and the arc-shaped flanging is embedded into the arc-shaped groove to form a double fixation, so as to realize the high-strength connection and fixation between the base and the top cover. Its structure is simple, easy to disassemble and assemble, and it will not be damaged even after repeated disassembly and assembly.

[0026] As Figures 1 to 3 shown, a reinforced self-locking cover cable tray includes a base 1 and a top cover 2 covering the base 1. Among them, the top of both sides of the base 1 of this embodiment is provided with a first sliding connection part 3 formed by stamping, and the bottom of both sides of the top cover 2 is provided with a second sliding connection part 4 formed by stamping for sliding into the first sliding connection part 4 to form a fixation, and the first sliding connection part 3 and the second sliding connection part 4 are adapted to each other.

[0027] In this embodiment, when manufacturing the production base 1 and the top cover 2, the first sliding connection part 3 and the second sliding connection part 4 are formed by simple folding at the assembly connection of the base 1 and the top cover 2. When assembling the base 1 and the top cover 2, only need to smoothly slide the second sliding connection part 4 into and snap it into the first sliding connection part 3, then the stable connection and fixation between the base 1 and the top cover 2 can be realized. Its disassembly and assembly are convenient. Only need to slide the top cover 2 into and out of the base 1 to realize disassembly. The structure of sliding snap connection can also avoid damage at the connection of the base 1 and the top cover 2 after multiple disassembly and assembly, and can improve the service life and overall durability of the frame body.

[0028] As Figure 1 shown, the cross-sections of the first sliding connection part 3 and the second sliding connection part 4 of this embodiment are both semi-circular with the opening facing outwards. The first sliding connection part 3 and the second sliding connection part 4 form two semi-circular arc structures that slide and clamp with each other. The semi-circular arc can evenly disperse the force acting on the connection part of the frame body, and effectively balance the tension in each area, reduce the stress concentration in the local area, provide better compressive resistance and bending resistance, and increase the structural strength and stability of the connection part of the frame body.

[0029] Furthermore, the opening width of the second sliding connection part 4 of this embodiment is greater than that of the first sliding connection part 3, so that the second sliding connection part 4 is slidably snapped into the first sliding connection part 3 by interference fit. The production material of the frame body is alloy, which has certain elasticity and toughness. The design of the second sliding connection part 4 in terms of the opening size is slightly larger than that of the first sliding connection part 3. The second sliding connection part 4 can be embedded into the first sliding connection part 3 by means of interference fit to ensure the firm connection between the base 1 and the top cover 2 and avoid loosening.

[0030] As Figure 2 shown, an arc-shaped groove 5 formed by folding is provided between the top cover 2 and the second sliding connection part 4 of this embodiment. An arc-shaped flanging 6 for snapping into the arc-shaped groove 5 is formed by folding the top of the first sliding connection part 3 radially outwards. The arc-shaped groove 5 is adapted to the arc-shaped flanging 6. During the manufacturing process of the frame body, when forming the connection structure by folding, an arc-shaped groove 5 in the shape of a semi-circle is left between the top cover 2 and the second sliding connection part 4 by folding, and an arc-shaped flanging 6 is formed by folding the top of the first sliding connection part 3 outwards. When sliding the second sliding connection part 4 into the first sliding connection part 3, the arc-shaped flanging 6 is also slid into the arc-shaped groove 5 to form a double locking mechanism, making the connection between the top cover 2 and the base 1 more stable, effectively preventing the top cover 2 from loosening or falling off due to external force, and improving the overall structural stability of the cable tray. And the arc-shaped flanging 6 can strengthen the structural strength of the base 1 and can improve the overall strength performance of the first sliding connection part 3 and the frame body.

[0031] As Figure 3As shown in the figure, anti-slip lines 7 are provided on the contact end faces of the first sliding connection part 3 and the second sliding connection part 4 of this embodiment. By engraving anti-slip lines 7 on the contact surface between the first sliding connection part 3 and the second sliding connection part 4, the friction after sliding connection is increased, preventing the top cover 2 from slipping when the frame shakes and tilts, and further improving the fastening and durability of the connection.

[0032] As Figure 1 shown in the figure, a reinforcing rib 8 is provided between the first sliding connection part 3 of this embodiment and the top of the base 1, which can effectively disperse the stress applied to the first sliding connection part 3, strengthen the structural strength and stiffness of the first sliding connection part 3, and effectively prevent the arc groove of the first sliding connection part 3 from deforming under stress, ensuring the long-term stability and durability of the frame connection structure.

[0033] In summary, the beneficial effects of this embodiment are as follows: In this embodiment, a connection structure formed by folding the connection ends of the base 1 and the top cover 2 is integrally manufactured, and the second sliding connection part 4 is designed to slide in by an interference fit and closely combine with the first sliding connection part 3. At the same time, by embedding the arc-shaped flanging 6 into the arc-shaped groove 5, a double locking mechanism is constructed. High-strength connection and fixation between the base 1 and the top cover 2 can be achieved, and the arc-shaped flanging 6 can strengthen the structural strength of the base 1 to ensure the service life. Engraving anti-slip lines 7 on the contact surface can avoid slipping. Its structure is simple and easy to disassemble and assemble, and repeated disassembly and assembly can be avoided to cause damage.

[0034] The above-described embodiments are only the preferred embodiments of the present invention, and the protection scope of the present invention cannot be limited thereby. Any non-substantial changes and modifications made by those skilled in the art on the basis of the present invention shall fall within the protection scope of the present invention.
