The first direction is the horizontal longitudinal direction, and the second direction is a direction different from the horizontal longitudinal direction.

[0037] Before the detailed introduction, it is necessary to understand the application scenario of the present utility model. Cable trays are often laid in different environments and often need to pass through complex working environments, such as high-temperature, high-humidity, dusty, and oily areas. Therefore, it is very inconvenient if corners need to be designed during cable laying. Moreover, cables have a certain hardness, and different cables can be bent at different angles. Cable trays are usually laid first, and then cables are laid. Therefore, if the bending situation of the specific cables to be laid is not considered, the cable trays with fixed bends designed often cannot be used.

[0038] The present utility model will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0039] As Figures 1-4 shown, it is a schematic diagram of the overall structure of the present utility model:

[0040] An elbow cable tray, the first cable tray main body 1 has two symmetrical side plates 2 and a bottom plate 3, enclosing an open semi-surrounding structure, and a first hinge end 4 is provided on the first cable tray main body 1; the two symmetrical side walls 6 and a bottom wall 7 of the second cable tray main body 5 also enclose an open semi-surrounding structure, and a second hinge end 8 is provided on the second cable tray main body 5. The second hinge end 8 is hinged to the first hinge end 4 to form a first hinge point. A fixed seat 9 is fixedly connected to the first cable tray main body 1; a limiting strip 10 is hinged to the fixed seat 9. A limiting groove 11 with a long strip-shaped through hole is provided on the limiting strip 10, and the limiting groove 11 is used for accommodating the sliding of a slider 12. One end of the slider 12 is fixedly connected to the side wall 6 of the second cable tray main body 5, and the other end of the slider 12 is provided with an external thread and is threadedly connected to a nut 13. When the second cable tray main body 5 rotates around the first hinge point, the slider 12 slides in the limiting groove 11; when the slider 12 slides to the required position, the nut 13 is tightened and pressed on the limiting strip 10 to fix the position of the slider 12 in the limiting groove 11. A section of the slider 12 in the limiting groove 11 is a smooth section to reduce the friction force during the sliding process. The connection between the slider 12 and the second cable tray main body 5 can be fixed connections such as welding, threaded connection, and riveting. In order to improve the convenience during the rotation process, the nut 13 is set as a wing-shaped nut 13.

[0041] It should be noted that in order to increase the stability of the second cable tray main body 5 during sliding and positioning, the limiting strip 10, the slider 12, and the nut 13 are all symmetrically arranged on the two side walls 6. The self-weight of the second cable tray main body 5 is relatively heavy, and the cables installed in it are also heavy. Moreover, when bending, a relatively large force will act on the second cable tray main body 5. Therefore, if only one side is stressed, a certain degree of deformation will occur to the second cable tray main body 5. A limiting sliding mechanism composed of paired limiting strips 10, sliders 12, and nuts 13 needs to be provided on both side walls 6. During the angle adjustment of the second cable tray main body 5, they will share the force together to resist its own gravity and the tensile stress of the cables.

[0042] Generally, inward curling edges 14 are provided on the side plates 2 and the side walls 6, and their shapes are circular arcs curling inward. The provision of the inward curling edges 14 not only increases the strength of the cable tray, but also improves its safety during installation and use. It avoids the cables being cut by the sharp edges of the cable tray, and also avoids the installers and maintainers from being cut. When the cable tray is subjected to external forces, the inward curling edges 14 can effectively disperse and absorb the impact force, and the specific dimensions and shapes can be designed according to actual requirements.

[0043] Furthermore, the cover body 15 is made of the same material as the first cable tray body 1 and the second cable tray body 5, and its shape is adapted to the size of the opening, ensuring that it can be tightly closed at the openings of the first cable tray body 1 and the second cable tray body 5.

[0044] It should be noted that the lock 16 is provided at the inner edge of the cover body 15. The lock 16 is in a Z-shaped structure. The upper end of the Z shape is fixedly connected to the knob 17, so that the lock 16 can effectively rotate following the knob 17 during operation. The lower end of the Z shape is an extended lock tongue 18. During the rotation process, when the lock tongue 18 is located at the lower end of the inward curling edge 14 mentioned above, the locking function is realized. The Z-shaped design of the lock 16 enables it to closely cooperate with the knob 17 during rotation, ensuring the stability of locking. The setting position of the lock 16 is at the inner edge of the cover body 15, which can not only ensure the locking effect, but also does not affect the appearance of the cover body 15. The shape and size of the knob 17 are reasonably designed for the convenience of users to operate. During the operation, the user can drive the lock 16 to rotate by rotating the knob 17, thereby realizing the locking of the cover body 15 with the first cable tray body 1 or the second cable tray body 5. The fixed connection between the knob 17 and the lock 16 ensures the synchronous movement of the two during operation.

[0045] It should be noted that both the lock 16 and the knob 17 are symmetrically provided at the inner edge of the cover body 15, that is, there are locking structures at both edges of the cover body 15 to ensure the stability during the locking process. The lock 16 is provided on the cover body 15 corresponding to the side plate 2 or the side wall 6. The lock 16 is made of metal, and the lock tongue 18 can firmly hold the inward curling edge 14 of the side plate 2 or the side wall 6, ensuring the tight connection between the cover body 15 and the cable tray body. The knob 17 is made of plastic, and its surface is provided with anti-slip textures for the convenience of users to operate. By rotating the knob 17, the lock 16 is locked or unlocked with the side plate 2 or the side wall 6.

[0046] Furthermore, the knob 17 has two side wings 19. The side wings 19 are symmetrically provided on the sides of the knob 17. The lengths of the two side wings 19 are approximately the diameter size of the knob 17, and the widths are appropriate for easy gripping and operation. The surfaces of the two side wings 19 are provided with anti-slip textures to increase the friction during gripping and improve the stability of operation.

[0047] It should be noted that the pipe groove 20 is arranged on the first bridge body 1 and the second bridge body 5, presenting an inverted U-shaped structure, generally made of stainless steel or other heat-dissipating materials. One end of the inverted U-shaped structure is open, facilitating the installation and maintenance of independent cables. The number of the pipe grooves 20 can be set according to requirements. The pipe grooves 20 can extend continuously along the extending direction of the bridge or be arranged intermittently.

[0048] Furthermore, two opposite circular protrusions 21 are provided inside the pipe groove 20. The circular protrusions 21 extend along the extending direction of the pipe groove 20, forming two symmetrical closings at the opening of the pipe groove 20. The circular protrusions 21 can increase the strength of the pipe groove 20 and are also beneficial to the clamping of the cable by the pipe groove 20.

[0049] It should be noted that the ventilation holes 22 are arranged on the side plate 2, playing a ventilation role, which helps with heat dissipation and improves the air quality inside the bridge. Generally, they are integrally formed by casting or can be formed by stamping.

[0050] In summary, through the specific description of the above embodiments, the elbow bridge of the present utility model demonstrates the novelty and practicality of its structural design. This bridge is not only convenient for installation and maintenance, but also has a stable structure, high load-bearing capacity and good performance, and is suitable for the needs of cable laying and protection in various occasions.

[0051] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
