Description

Technical Field

[0001] This utility model relates to the field of cable tray technology, and specifically to an easy-to-disassemble cable tray. Background Technology

[0002] With the continuous development of informatization in my country, all kinds of information products are ubiquitous in people's lives. As the carrier of information and electricity, cables are also constantly developing. Cable installation is divided into surface installation and concealed installation. When cables are surface-mounted, cable trays are needed to support them. This not only makes them look neat and tidy, but also improves their safety. Cable trays are divided into trough type, tray type, ladder type, and mesh type structures. Tray-type cable trays are widely used in life due to their advantages such as light weight, large load capacity, beautiful appearance, simple structure, and convenient installation.

[0003] Currently, the brackets and supports of cable trays are not easy to disassemble, and the supports are fixed structures that cannot be extended or retracted to adjust the height. This makes them unsuitable for different installation locations and different height requirements. Utility Model Content

[0004] This utility model provides an easy-to-disassemble cable tray, which can effectively solve the problems of cable tray arms and supports being inconvenient to disassemble, and supports being fixed structures that cannot be extended or retracted to adjust height, thus making them unsuitable for different installation locations and different height requirements.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] An easy-to-assemble cable tray includes a cable box, a support arm fixedly connected to the bottom of the cable box, a support frame slidably connected to the inner walls of the left and right sides of the support arm, a telescopic support frame slidably connected to the inner wall of the support frame, and an anti-movement mechanism provided on the inner walls of the left and right sides behind the support arm.

[0007] A further improvement of the present invention is that: the support arm includes two square support blocks, and a rectangular support block is fixedly connected to the opposite face of the two square support blocks. A T-shaped sliding groove is provided at the rear of the square support blocks, and a square groove extending into the T-shaped sliding groove is provided on the upper rear side of the square support blocks. Circular grooves are provided on the front and rear sides of the inner wall of the two square grooves that are far apart. The upper part of the rectangular support block is fixedly connected to the lower part of the cable box.

[0008] A further improvement of the present invention is that the support frame includes two square support sleeves, a rectangular block is fixedly connected to the front of the square support sleeve, a T-shaped sliding block is fixedly connected to the bottom of the square support sleeve, a square sliding hole is opened in the front of the rectangular block to penetrate into the interior of the square support sleeve, a second square sliding hole is opened on the left side of the rectangular block to penetrate to the right exterior, and the outer wall of the T-shaped sliding block is slidably connected to the inner wall of the T-shaped sliding groove.

[0009] A further improvement of this utility model is that: the telescopic support frame includes two inner telescopic square support blocks, an mounting plate is fixedly connected to the top of the inner telescopic square support blocks, a square sliding block is fixedly connected to the lower front of the inner telescopic square support blocks, a screw is threadedly connected to the inner wall of the square sliding block, and a nut is threadedly connected to the outer wall of the two sides of the screw that are far apart from each other. The outer wall of the inner telescopic square support block is slidably connected to the inner wall of the square support sleeve, the outer wall of the square sliding block is slidably connected to the inner wall of the square sliding hole, and the outer wall of the screw is slidably connected to the inner wall of the square sliding hole.

[0010] A further improvement of this utility model is that the anti-movement mechanism includes two rectangular plates, and arc-shaped blocks are fixedly connected to the opposite sides of the two rectangular plates. A semi-circular handle is fixedly connected to the top of the rectangular plates. Circular rotating columns are fixedly connected to the front and rear sides of the arc-shaped blocks. A coil spring is fixedly connected to the outer wall of the circular rotating column. The rectangular plates are placed in a square groove. The outer walls of the opposite sides of the circular rotating columns are rotatably connected to the inner walls of the opposite sides of the circular groove. The other end of the coil spring is fixedly connected to its inner wall in the circular groove.

[0011] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0012] 1. By grasping the screw and moving it upwards, the square sliding block and nut move, causing the screw, square sliding block, and square sliding hole to slide together. This allows the inner telescopic square support block to slide with the square support sleeve, enabling telescopic movement. After adjusting to a suitable height, rotate the nut so that it rotates with the screw thread, pressing the rectangular block to stop and fix it. Different installation sites have different height requirements, and fixed-height columns are difficult to meet the complex and varied installation environments. For example, in some old building renovation projects, there may be large height differences. Telescopic support frames with adjustable height can adapt well to such environments. Telescopic support frames with adjustable height allow cable trays to adapt to different installation heights and terrain conditions. In uneven areas, the cable tray can be stably installed by adjusting the height of the column, which improves the versatility of the cable tray and allows it to be used in more different places.

[0013] 2. When disassembling the support frame and telescopic support frame, grasp the semi-circular handle and rotate it to rotate the circular rotating column and the circular groove. After the circular rotating column pulls one end of the coil spring, slide the square support sleeve through the T-shaped sliding block and the T-shaped sliding groove, then remove it for disassembly. Similarly, when installing it, grasp the semi-circular handle and rotate it to install the square support sleeve. Then release the semi-circular handle to allow the coil spring to pull the circular rotating column and the rectangular plate back to their original positions. The installation and disassembly of traditional cable tray supports and brackets often require complex tools and a large number of people. The process of frequently adjusting or maintaining cables is laborious and time-consuming. In scenarios where frequent cable adjustments or maintenance are required, such as temporary event areas or areas where equipment is frequently upgraded, this inconvenience can seriously affect work efficiency. The design of easily disassembled brackets and supports effectively solves this problem. The easily disassembled brackets and supports can be quickly spliced ​​and fixed during installation without the need for cumbersome bolt tightening or welding, which greatly shortens the installation time. During maintenance, the parts that need to be inspected can be quickly removed, making it convenient for staff to inspect, repair or replace cables, reducing maintenance workload and downtime.

[0022] To make the technical means, creative features, objectives, and effects of this utility model easier to understand, the following describes this utility model in conjunction with specific embodiments:

[0023] like Figure 1-2 As shown, this utility model provides an easy-to-disassemble cable tray, including a cable box 1, a support arm 2 fixedly connected to the bottom of the cable box 1, a support frame 3 slidably connected to the inner walls of the left and right sides of the support arm 2, a telescopic support frame 4 slidably connected to the inner wall of the support frame 3, and an anti-movement mechanism 5 provided on the inner walls of the left and right sides behind the support arm 2.

[0024] The cable tray can be extended and retracted by the support frame 3 and the telescopic support frame 4 to adapt to different installation heights and terrain conditions. In uneven areas, the cable tray can be installed stably by adjusting the height of the column, which improves the versatility of the cable tray and allows it to be used in more different places. The anti-movement mechanism 5 allows the bracket 2 and the support frame 3 to be quickly spliced ​​and fixed during installation without the need for cumbersome bolt tightening or welding, which greatly shortens the installation time. During maintenance, it can be quickly dismantled, which is convenient for staff to inspect, repair or replace cables, reducing maintenance workload and downtime.

[0025] like Figure 3-4 As shown, this utility model provides a technical solution: the support arm 2 includes two square support blocks 21, and a rectangular support block 22 is fixedly connected to the opposite face of the two square support blocks 21. A T-shaped sliding groove 23 is provided at the rear of the square support blocks 21. A square groove 24 is provided on the upper rear side of the square support blocks 21, which extends into the interior of the T-shaped sliding groove 23. Circular grooves 25 are provided on the front and rear sides of the inner wall of the two square grooves 24 that are far apart. The upper part of the rectangular support block 22 is fixedly connected to the lower part of the cable box 1.

[0026] like Figure 5-6The present invention provides a technical solution: the support frame 3 includes two square support sleeves 31, a rectangular block 33 is fixedly connected to the front of the square support sleeve 31, a T-shaped sliding block 32 is fixedly connected to the bottom of the square support sleeve 31, a square sliding hole 34 penetrating into the interior of the square support sleeve 31 is opened in the front of the rectangular block 33, a second square sliding hole 35 penetrating to the right exterior is opened on the left side of the rectangular block 33, the outer wall of the T-shaped sliding block 32 is slidably connected to the inner wall of the T-shaped sliding groove 23, and the telescopic support frame 4 includes two inner... A telescopic square support block 41 is provided. An mounting plate 42 is fixedly connected to the top of the inner telescopic square support block 41. A square sliding block 43 is fixedly connected to the lower front of the inner telescopic square support block 41. A screw 44 is threadedly connected to the inner wall of the square sliding block 43. Nuts 45 are threadedly connected to the outer wall of the two sides of the screw 44 that are far apart. The outer wall of the inner telescopic square support block 41 is slidably connected to the inner wall of the square support sleeve 31. The outer wall of the square sliding block 43 is slidably connected to the inner wall of the square sliding hole 34. The outer wall of the screw 44 is slidably connected to the inner wall of the square sliding hole 35.

[0027] After rotating the anti-movement mechanism 5, sliding the T-shaped sliding block 32 and the T-shaped sliding groove 23, and then releasing the anti-movement mechanism 5 to return it to its original position, the square support sleeve 31 and the inner telescopic square support block 41 are installed.

[0028] The support frame 3 and the telescopic support frame 4 can be extended and retracted. During use, by grasping the screw 44 and moving it upwards, the square sliding block 43 and nut 45 move, causing the screw 44, square sliding block 43, square sliding hole 34, and square sliding hole 35 to slide. This allows the inner telescopic square support block 41 to slide with the square support sleeve 31, thus extending and retracting. After adjusting to a suitable height, the nut 45 is rotated so that it rotates with the screw 44, pressing the rectangular block 33 to stop and fix it. Different installation locations have different height requirements, and fixed-height columns cannot meet the complex and varied installation environments. For example, in some old building renovation projects, there may be significant height differences. The telescopic support frame 4, with its adjustable height, can adapt well to such environments. The telescopic support frame 4 allows the cable tray to adapt to different installation heights and terrain conditions. In uneven areas, the cable tray can be stably installed by adjusting the column height, improving its versatility and allowing it to be used in more diverse locations.

[0029] like Figure 7The present invention provides a technical solution: the anti-movement mechanism 5 includes two rectangular plates 51, and arc-shaped blocks 53 are fixedly connected to the opposite sides of the two rectangular plates 51. A semi-circular handle 52 is fixedly connected to the top of the rectangular plates 51. Circular rotating columns 54 are fixedly connected to the front and rear sides of the arc-shaped blocks 53. A coil spring 55 is fixedly connected to the outer wall of the circular rotating columns 54. The rectangular plates 51 are placed in a square groove 24. The outer wall of the opposite side of the circular rotating columns 54 is rotatably connected to the inner wall of the opposite side of the circular groove 25. The other end of the coil spring 55 is fixedly connected to the inner wall of the circular groove 25.

[0030] The anti-movement mechanism 5 facilitates the disassembly of the support frame 3 and the telescopic support frame 4. When disassembling the support frame 3 and the telescopic support frame 4, grasp the semi-circular handle 52 and rotate it. This causes the circular rotating column 54 and the circular groove 25 to rotate, pulling one end of the coil spring 55. Then, slide the square support sleeve 31 through the T-shaped sliding block 32 and the T-shaped sliding groove 23, and remove it for disassembly. Similarly, when installing it, grasp the semi-circular handle 52 and rotate it. After installing the square support sleeve 31, release the semi-circular handle 52, causing the coil spring 55 to pull the circular rotating column 54 and the rectangular plate 51 back to their original positions. (Traditional cable bridge) The installation and disassembly of the brackets and supports often require complex tools and a lot of manpower, and are time-consuming. In some scenarios where cables need to be frequently adjusted or maintained, such as temporary activity areas or areas where equipment is frequently updated, this inconvenience can seriously affect work efficiency. The design of easily disassembled brackets and supports effectively solves this problem. The easily disassembled supports 2 and support frame 3 can be quickly spliced ​​and fixed during installation without the need for cumbersome bolt tightening or welding operations, which greatly shortens the installation time. During maintenance, the parts that need to be inspected can be quickly removed, making it convenient for staff to inspect, repair or replace cables, reducing maintenance workload and downtime.

[0031] The working principle of this easy-to-disassemble cable tray is explained in detail below: After rotating the anti-movement mechanism 5, the T-shaped sliding block 32 and the T-shaped sliding groove 23 are slid together, and then the anti-movement mechanism 5 is released to return to its original position, thereby installing the square support sleeve 31 and the inner telescopic square support block 41.

[0032] The support frame 3 and the telescopic support frame 4 can be extended and retracted. During use, by grasping the screw 44 and moving it upwards, the square sliding block 43 and nut 45 move, causing the screw 44, square sliding block 43, square sliding hole 34, and square sliding hole 35 to slide. This allows the inner telescopic square support block 41 to slide with the square support sleeve 31, thus extending and retracting. After adjusting to a suitable height, the nut 45 is rotated so that it rotates with the screw 44, pressing the rectangular block 33 to stop and fix it. Different installation locations have different height requirements, and fixed-height columns cannot meet the complex and varied installation environments. For example, in some old building renovation projects, there may be significant height differences. The telescopic support frame 4, with its adjustable height, can adapt well to such environments. The telescopic support frame 4 allows the cable tray to adapt to different installation heights and terrain conditions. In uneven areas, the cable tray can be stably installed by adjusting the column height, improving its versatility and allowing it to be used in more diverse locations.

[0033] The anti-movement mechanism 5 facilitates the disassembly of the support frame 3 and the telescopic support frame 4. When disassembling the support frame 3 and the telescopic support frame 4, grasp the semi-circular handle 52 and rotate it. This causes the circular rotating column 54 and the circular groove 25 to rotate, pulling one end of the coil spring 55. Then, slide the square support sleeve 31 through the T-shaped sliding block 32 and the T-shaped sliding groove 23, and remove it for disassembly. Similarly, when installing it, grasp the semi-circular handle 52 and rotate it. After installing the square support sleeve 31, release the semi-circular handle 52, causing the coil spring 55 to pull the circular rotating column 54 and the rectangular plate 51 back to their original positions. (Traditional cable bridge) The installation and disassembly of the brackets and supports often require complex tools and a lot of manpower, and are time-consuming. In some scenarios where cables need to be frequently adjusted or maintained, such as temporary activity areas or areas where equipment is frequently updated, this inconvenience can seriously affect work efficiency. The design of easily disassembled brackets and supports effectively solves this problem. The easily disassembled supports 2 and support frame 3 can be quickly spliced ​​and fixed during installation without the need for cumbersome bolt tightening or welding operations, which greatly shortens the installation time. During maintenance, the parts that need to be inspected can be quickly removed, making it convenient for staff to inspect, repair or replace cables, reducing maintenance workload and downtime.

[0034] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
