Description

Technical Field

[0001] This utility model belongs to the field of cable tray technology, specifically relating to a cable tray device with adjustable height and angle. Background Technology

[0002] Cable trays, also known as cable supports or cable trays, are supports used in wiring systems to support, protect, and manage cables and wires. Cable trays act as a cable skeleton, supporting cables laid in buildings, tunnels, caves, and other locations. Because most cables are flexible and cannot be laid independently, the rigid structural characteristics of cable trays make them an ideal choice for supporting cables.

[0003] Currently, existing cable tray installations typically support the cable trays using bottom brackets. However, the height of these bottom brackets is often fixed, making it impossible to adjust their height after production. This results in a fixed cable tray height that cannot be adjusted according to actual conditions, thus reducing the practicality of the cable tray installation. Utility Model Content

[0004] The purpose of this utility model is to provide a cable tray device with adjustable height and angle, which aims to solve the problem that existing cable tray devices in the prior art are usually supported by a bottom bracket during use. However, the height of the bottom bracket of traditional cable tray devices is often fixed, so its height cannot be adjusted after production. This makes the height of the cable tray fixed and unable to be adjusted according to the actual situation, thereby reducing the practicality of the cable tray device.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an adjustable height and angle cable tray device, comprising a cable tray body, characterized in that: a top plate is provided on the top of the cable tray body, columns are provided at the four bottom corners of the cable tray body, four first telescopic frames are provided at the four bottom corners of the cable tray body, and two connecting columns are provided at the bottom of the cable tray body.

[0006] The bottom of the cable tray body is provided with two second telescopic frames. A connecting plate is connected between the upright and the connecting column. The two connecting columns are rotatably connected to a lead screw through a bearing. A threaded connecting block is connected to one end of each of the two second telescopic frames. A first bevel tooth is connected to one end of the lead screw. A rotating rod passes through the outer wall of the connecting column. A second bevel tooth is connected to one end of the rotating rod. A crank is installed at the end of the rotating rod away from the second bevel tooth.

[0007] As a preferred embodiment of the adjustable height and angle cable tray device of this utility model, the connecting column is located between two columns, and the end of the first telescopic frame away from the cable tray body extends through into the interior of the column.

[0008] As a preferred embodiment of the adjustable height and angle cable tray device of this utility model, the first bevel tooth and the second bevel tooth mesh with each other, and the rotating rod forms a rotating connection structure with the connecting column through the bearing.

[0009] As a preferred embodiment of the adjustable height and angle cable tray device of this utility model, the outer wall of the connecting column is provided with a sliding groove, the outer wall of the second telescopic frame is connected with a slider, one end of each of the two first telescopic frames and one second telescopic frame is rotatably connected with a T-shaped slider, and three slide rails are installed at the bottom of the cable tray body.

[0010] As a preferred embodiment of the adjustable height and angle cable tray device of this utility model, the second telescopic frame can form a sliding connection structure with the connecting column through a sliding groove and a slider.

[0011] As a preferred embodiment of the adjustable height and angle cable tray device of this utility model, the outer wall of the slider is connected to a scale display frame, and the outer wall of the connecting column is provided with a scale ruler.

[0012] As a preferred embodiment of the adjustable height and angle cable tray device of this utility model, the scale display frame is C-shaped and is in contact with the outer wall of the connecting column.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] By simultaneously rotating two cranks, the screw is driven to rotate by the meshing relationship between the first and second bevel teeth. At this time, the threaded connecting block connected to the outer wall will drive the second telescopic frame to rise and fall along the slide, thereby adjusting the overall height of the cable tray device. Furthermore, by rotating a single crank, the height of one side of the cable tray body will be adjusted and it will tilt to one side, thereby achieving angle adjustment and improving practicality.

[0015] When the height of the cable tray body is adjusted by cranking, the second telescopic frame moves along the slide groove under the action of the slider. At the same time, the scale display frame also moves along the outer wall of the connecting column under the action of the slider. The staff can accurately know the height of the top cable tray body by checking the stopping position of the scale display frame on the outer wall of the two connecting columns.

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] Please see Figures 1-6 The present invention provides the following technical solution: a cable tray device with adjustable height and angle, including a cable tray body 1, a top plate 2 on the top of the cable tray body 1, columns 3 at the four corners of the bottom of the cable tray body 1, a first telescopic frame 4 rotatably connected at the four corners of the bottom of the cable tray body 1, and two connecting columns 5 at the bottom of the cable tray body 1.

[0026] The bottom of the cable tray body 1 is rotatably connected to two second telescopic frames 6. A connecting plate 7 is connected between the column 3 and the connecting column 5. The inside of the two connecting columns 5 is rotatably connected to a lead screw 8 through a bearing. A threaded connecting block 9 is connected to one end of the two second telescopic frames 6. A first bevel tooth 10 is connected to one end of the lead screw 8. A rotating rod 11 passes through the outer wall of the connecting column 5. A second bevel tooth 12 is connected to one end of the rotating rod 11. A crank 13 is installed at the end of the rotating rod 11 away from the second bevel tooth 12.

[0027] Among them, the upright column 3 and the first telescopic frame 4 adopt a hollow structure. The first telescopic frame 4 and the cable tray body 1 are connected by a rotating method, which can achieve rotation and tilting when adjusting the angle. The connecting column 5 is located between the two upright columns 3. The end of the second telescopic frame 6 away from the cable tray body 1 extends through to the inside of the connecting column 5. The end of the screw 8 away from the bearing is threaded through the threaded connecting block 9. The crank handle 13 is Z-shaped. The end of the second telescopic frame 6 is adapted to the inner size of the connecting column 5.

[0028] It should be noted that the cables are placed inside the cable tray body 1 and then covered by the top plate 2, which serves to protect and support the cables.

[0029] Preferably, the connecting column 5 is located between the two columns 3, and the end of the first telescopic frame 4 away from the cable tray body 1 extends through into the interior of the column 3. The first bevel tooth 10 and the second bevel tooth 12 mesh with each other, and the rotating rod 11 forms a rotating connection structure with the connecting column 5 through the bearing. The outer wall of the connecting column 5 is provided with a sliding groove 14, and the outer wall of the second telescopic frame 6 is connected with a slider 15. One end of each of the two first telescopic frames 4 and one second telescopic frame 6 is rotatably connected with a T-shaped slider 18. Three slide rails 19 are installed at the bottom of the cable tray body 1. The second telescopic frame 6 can form a sliding connection structure with the connecting column 5 through the sliding groove 14 and the slider 15.

[0030] It should be noted that one end of each of the two first telescopic frames 4 and one second telescopic frame 6 can form a sliding connection structure with the cable tray body 1 through a T-shaped slider 18 and three slide rails 19, thereby providing room for adjustment of the angle.

[0031] In practical use, by simultaneously rotating the two cranks 13, the lead screw 8 is driven to rotate by the meshing relationship between the first bevel tooth 10 and the second bevel tooth 12. At this time, the threaded connecting block 9 connected to the outer wall will drive the second telescopic frame 6 to rise and fall along the slide groove 14, thereby adjusting the overall height of the cable tray device. Furthermore, by rotating a single crank 13, the height of one side of the cable tray body 1 will be adjusted and it will tilt to one side, thereby achieving angle adjustment and improving practicality.

[0032] It should be noted that when the crank handle 13 is turned clockwise, the screw 8 rotates and the threaded connecting block 9 will drive the second telescopic frame 6 to rise. Conversely, when the crank handle 13 is turned counterclockwise, the screw 8 rotates and the threaded connecting block 9 will drive the second telescopic frame 6 to fall.

[0033] Preferably, the outer wall of the slider 15 is connected to a scale display frame 16, and the outer wall of the connecting post 5 is provided with a scale ruler 17. The scale display frame 16 is C-shaped and fits against the outer wall of the connecting post 5.

[0034] In practical use, when the height of the cable tray body 1 is adjusted by crank 13, the second telescopic frame 6 will move along the slide groove 14 under the action of slider 15. At the same time, the scale display frame 16 will also move along the outer wall of the connecting column 5 under the action of slider 15. The staff can accurately know the height of the top cable tray body 1 by looking at the stopping position of the scale display frame 16 on the outer wall of the two connecting columns 5.

[0035] Working principle: First, when adjusting the height of the cable tray body 1, by simultaneously rotating two cranks 13, the lead screw 8 is rotated by the meshing relationship between the first bevel gear 10 and the second bevel gear 12. At this time, the threaded connecting block 9 connected to the outer wall will drive the second telescopic frame 6 to rise and fall along the slide groove 14, thereby adjusting the overall height of the cable tray device. By rotating a single crank 13, the height of one side of the cable tray body 1 will be adjusted and tilted to one side, thereby achieving angle adjustment. During the adjustment process, the second telescopic frame 6 will move along the slide groove 14 under the action of the slider 15. At the same time, the scale display frame 16 will also move along the outer wall of the connecting column 5 under the action of the slider 15. The operator can accurately know the height of the top cable tray body 1 by observing the stopping position of the scale display frame 16 on the outer wall of the two connecting columns 5.

[0036] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model.
