Description

Technical Field

[0001] This utility model relates to the field of cable laying equipment technology, and in particular to an aluminum alloy cable tray bend with adjustable angle. Background Technology

[0002] During cable laying, aluminum alloy cable tray bends, as key components connecting two straight cable tray sections, need to adapt to the corner angle requirements under different installation environments.

[0003] However, in the existing technology, traditional cable tray bends are mostly designed with fixed angles, which cannot flexibly adjust the corner angle according to the actual working conditions on site. During installation, angle mismatch is prone to occur, requiring customized bends with specific angles, which not only increases construction costs but also extends the construction period. Furthermore, some adjustable bends have defects such as low angle adjustment accuracy, poor connection stability, and insufficient load-bearing capacity. Utility Model Content

[0004] The purpose of this invention is to solve the problems of fixed angles and inflexible adjustment of traditional cable tray bends, as well as low accuracy and poor stability of adjustable bends in the existing technology, and to propose an aluminum alloy cable tray bend with adjustable angle.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an aluminum alloy cable tray bend with adjustable angle, comprising a first cable tray and a second cable tray. A second protrusion is fixedly installed at the corner of the first cable tray, and a first protrusion is fixedly installed at the corner of the second cable tray. The first protrusion and the second protrusion are rotatably connected. Positioning blocks are rotatably connected to the upper and lower ends of the first cable tray and the upper and lower ends of the second cable tray. A connecting rod is threaded between the two positioning blocks. The surface of the connecting rod is provided with threaded grooves in opposite directions. A gap is left between the first protrusion and the second protrusion.

[0006] Preferably, a connecting plate is provided at the connection between the first cable tray and the second cable tray, and a reinforcing plate is fixedly installed at the corner of the connecting plate.

[0007] Preferably, a gap is left between the reinforcing plate and the first and second cable trays.

[0008] Preferably, both the bottom of the first cable tray and the bottom of the second cable tray are provided with arc-shaped strip holes.

[0009] Preferably, both the first cable tray and the second cable tray are provided with limiting screws, which are located inside the arc-shaped slot.

[0010] Preferably, a nut is threaded onto the rod of the limiting screw, the limiting screw passes through the first bridge frame and the connecting plate, and the nut is attached to the lower surface of the connecting plate.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0012] 1. In this utility model, the first cable tray and the second cable tray are rotatably connected by the first and second protrusions at the corner, which can realize the angle adjustment. The gap between the two provides space for rotation. When it is necessary to fix the angle, the positioning blocks rotatably connected at the upper and lower ends of the first and second cable trays are used. Through the connecting rod with the threaded grooves in opposite directions on the rotating surface, the two positioning blocks are moved towards or in opposite directions along the connecting rod, thereby driving the first and second cable trays to be adjusted to the required angle and fixed.

[0013] 2. In this utility model, the arc-shaped strip hole at the bottom of the first and second cable trays provides a moving trajectory for the limiting screw. When the angle between the first and second cable trays is adjusted, the internal limiting screw slides along the arc-shaped strip hole. At the same time, the limiting screw passes through the first cable tray and the connecting plate. By tightening the nut on the rod body, it is made to fit against the lower surface of the connecting plate, thereby fixing the position. Attached Figure Description

[0019] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0020] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0021] Example 1: As Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this utility model provides an aluminum alloy cable tray bend with adjustable angle. The first cable tray 1 and the second cable tray 2 are rotatably connected by the first protrusion 8 and the second protrusion 9 at the corner, which can realize angle adjustment. The gap 10 between the two provides space for rotation. When the angle needs to be fixed, the positioning blocks 4 rotatably connected at the upper and lower ends of the first cable tray 1 and the second cable tray 2 are used. Through the connecting rod 5 with oppositely oriented threaded grooves on the rotating surface, the two positioning blocks 4 move towards or in opposite directions along the connecting rod 5, thereby driving the first cable tray 1 and the second cable tray 2 to adjust to the required angle and fix them. The rotatable connection gap 10 between the first protrusion 8 and the second protrusion 9 ensures that the angle adjustment of the first cable tray 1 and the second cable tray 2 is flexible and smooth. The positioning blocks 4 at the upper and lower ends and the connecting rod 5 are synchronously linked through the reverse threaded grooves, which can quickly and stably fix the adjusted angle and improve the structural stability. The synergistic effect of each component not only ensures the multi-angle adjustment function at the corner of the cable tray, but also enhances the load-bearing capacity and connection reliability of the overall structure through the threaded connection positioning method, which is suitable for a variety of complex installation scenarios.

[0022] The specific settings and functions of this embodiment will be described in detail below.

[0023] Example 2: Figure 1 , Figure 2 and Figure 4 As shown, a connecting plate 3 is provided at the connection between the first cable tray 1 and the second cable tray 2. A reinforcing plate 6 is fixedly installed at the corner of the connecting plate 3. A notch 7 is left between the reinforcing plate 6 and the first cable tray 1 and the second cable tray 2. An arc-shaped strip hole 11 is opened at the bottom of the first cable tray 1 and the bottom of the second cable tray 2. A limiting screw 12 is provided inside the first cable tray 1 and the second cable tray 2. The limiting screw 12 is located inside the arc-shaped strip hole 11. A nut is threaded on the rod of the limiting screw 12. The limiting screw 12 passes through the first cable tray 1 and the connecting plate 3, and the nut is attached to the lower surface of the connecting plate 3.

[0024] The overall effect of this embodiment is that the first cable tray 1 and the second cable tray 2 are further fitted together by the connecting plate 3 at the connection point. The reinforcing plate 6 at the corner of the connecting plate 3 provides auxiliary support for the connection between the two. The notch 7 between the reinforcing plate 6 and the first cable tray 1 and the second cable tray 2 provides space for the cable tray angle adjustment. The arc-shaped strip hole 11 at the bottom of the first cable tray 1 and the second cable tray 2 provides a movement trajectory for the limiting screw 12. When the angle of the first cable tray 1 and the second cable tray 2 is adjusted, the internal limiting screw 12 slides along the arc-shaped strip hole 11, and at the same time, the limiting screw 1... 2. The first cable tray 1 and the connecting plate 3 are connected. By tightening the nut on the rod body, it is made to fit against the lower surface of the connecting plate 3, thus fixing the position. The connecting plate 3 enhances the overall integrity of the connection between the first cable tray 1 and the second cable tray 2. The reinforcing plate 6 improves the structural strength at the corner. The notch 7 avoids interference between components when adjusting the angle. The arc-shaped strip hole 11, together with the limiting screw 12 and the nut, ensures both the flexibility of angle adjustment and the precise fixing of the position, ensuring the stability of the connection. The cooperation of all components makes the cable tray both reliable and load-bearing in multi-angle adjustment, adapting to complex installation requirements.

[0025] The usage and working principle of this device are as follows: During use, the angle is first adjusted by rotating the first protrusion 8 and the second protrusion 9 at the corner of the first cable tray 1 and the second cable tray 2. The gap 10 between them provides space for rotation. During adjustment, the connecting plate 3 at the connection between the first cable tray 1 and the second cable tray 2 moves in coordination with the angle change. The reinforcing plate 6 at the corner of the connecting plate 3 moves synchronously, and the gap 7 between the reinforcing plate 6 and the first cable tray 1 and the second cable tray 2 prevents interference between components. Simultaneously, the limiting screws 12 at the bottom of the first cable tray 1 and the second cable tray 2 move along the arc-shaped slot 11. After sliding and adjusting the angle to the approximate position, rotate the connecting rod 5 with opposite threaded grooves on the surface between the upper and lower positioning blocks 4 of the first cable tray 1 and the second cable tray 2. This causes the two positioning blocks 4 to move towards or away from each other along the connecting rod 5, thereby driving the first cable tray 1 and the second cable tray 2 to make fine-tuning of the angle. During the fine-tuning process, the limiting screw 12 continues to slide along the arc-shaped strip hole 11 until the required angle is reached. Finally, tighten the nut on the limiting screw 12 so that it fits against the lower surface of the connecting plate 3, thus completing the fixation of the first cable tray 1, the second cable tray 2 and the connecting plate 3, and achieving precise fixation of the overall angle.

[0026] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
