Description

Technical Field

[0001] The utility model relates to the technical field of cable trays, in particular to a transition cable tray. Background Art

[0002] When wiring in a building, cables are usually arranged in a metal cable tray to guide the cables, and it is also more aesthetically pleasing from the outside. During the actual wiring process, at the turning point of the cable tray, due to its metal material, after the internal right-angle corner is arranged, when pulling and arranging the cables subsequently, it is easy to pull the cables, and the right-angle turning position damages the cables. In the prior art, the right-angle turning is sharpened, and the original right angle at the turning point is changed into two obtuse angles. To a certain extent, this avoids the problem of the cables being scratched. However, since the two obtuse angles are usually also formed by cutting and splicing, the connection part is still sharp and easy to scratch the cables. Content of the Utility Model

[0003] The technical problem to be solved by the utility model is, in view of the above-mentioned existing technical deficiencies, to provide a transition cable tray. By providing anti-scratch rollers at the joints between the inclined plate frame and the first plate frames and the second plate frames on both sides, when pulling the cables after the arrangement is completed, the anti-scratch rollers replace the original obtuse-angle joints to contact the cables, avoiding the problem of the cables being scratched and damaged by the sharpness of the obtuse angles; by using the cooperation of the guide rollers and the spring-back mechanism arranged through the bottom frame and the outer frame, when cables are arranged on the guide rollers and then pulled, when the cables are released, the spring-back pulling effect of the guide rollers leaves a part of the margin for the cables at the turning point, avoiding the problem of the cables being damaged due to being pulled too tightly.

[0004] To solve the above technical problems, the technical solution adopted by the utility model is: it includes a bottom frame and an outer frame installed and fixed on the bottom frame; the bottom frame includes a first frame plate and a second frame plate perpendicular to each other and an inclined frame plate arranged between the first frame plate and the second frame plate; the first frame plate, the second frame plate and the inclined frame plate are connected by side frame plates on both sides; anti-scratch rollers are arranged between the first frame plate and the inclined frame plate; anti-scratch rollers are arranged between the second frame plate and the inclined frame plate; both sides of the anti-scratch rollers are rotationally connected to the side frame plates; a guide roller is arranged parallel to the upper side of the inclined frame plate; the transverse two sides of the guide roller penetrate through the bottom frame and the outer frame; a spring-back mechanism for making the guide roller spring back is arranged on the part of the guide roller extending to the outer frame.

[0005] Further optimizing the technical solution, the spring-back mechanism includes a bottom plate arranged on the outer side of the inclined frame plate; and guide columns protruding upward on both sides arranged on the bottom plate; and inner columns bent and extended from both ends of the guide roller into the guide columns; a spring is arranged between the inner bottom of the guide column and the inner column.

[0006] Further optimizing the technical solution, the bottom plate is fixedly arranged on the outer side of the inclined frame plate by bolts.

[0007] To further optimize this technical solution, a notch facilitating the springback of the guide roller is provided along the springback direction of the guide roller on the side frame plate.

[0008] To further optimize this technical solution, notches facilitating the installation of the guide roller are provided on both sides of the outer frame.

[0009] Compared with the prior art, the present utility model has the following advantages: 1. The anti-scratching roller provided at the connection of the inclined plate frame and the first and second plate frames on both sides. This structure effectively ensures that when pulling the cable after the layout is completed, the anti-scratching roller contacts the cable instead of the original obtuse angle connection; 2. The guide roller penetrating the bottom frame and the outer frame cooperates with the springback mechanism. This structure effectively ensures that when the cable is set on the guide roller and the cable is pulled and laid, when the cable is released, the pulling effect of the springback of the guide roller leaves a certain margin for the cable at the turning point.

[0015] To better understand the purpose, structure and function of the present utility model, the following further describes in detail a transition cable tray of the present utility model with reference to the drawings.

[0016] As Figures 1-4As shown in the figure, a transition cable tray of the utility model includes a bottom frame 1 and an outer frame 2 fixedly installed on the bottom frame 1; the bottom frame 1 includes a first frame plate 3 and a second frame plate 4 perpendicular to each other, and an inclined frame plate 5 arranged between the first frame plate 3 and the second frame plate 4; the first frame plate 3, the second frame plate 4 and the inclined frame plate 5 are connected by side frame plates 7 on both sides; a scratch-proof roller 6 is arranged between the first frame plate 3 and the inclined frame plate 5; a scratch-proof roller 6 is arranged between the second frame plate 4 and the inclined frame plate 5; both sides of the scratch-proof roller 6 are rotationally connected to the side frame plates 7; a guide roller 8 is arranged parallel to the upper side of the inclined frame plate 5; both transverse sides of the guide roller 8 penetrate through the bottom frame 1 and the outer frame 2; a return mechanism for making the guide roller 8 return is arranged on the part of the guide roller 8 extending to the outer frame 2, and the return mechanism includes a bottom plate 9 arranged on the outer side of the inclined frame plate 5; the bottom plate 9 is fixedly arranged on the outer side of the inclined frame plate 5 by bolts; and guide columns 10 protruding upward on both sides are arranged on the bottom plate 9; and inner columns 11 bent and extended at both ends of the guide roller 8 are arranged in the guide columns 10; a spring 12 is arranged between the inner bottom of the guide column 10 and the inner column 11; a notch 13 for facilitating the return of the guide roller 8 is arranged on the side frame plate 7 along the return direction of the guide roller 8; notches 14 for facilitating the installation of the guide roller 8 are arranged on both sides of the outer frame 2.

[0017] During specific installation, as shown in Figures 1-4 the figure, after the position of the bottom frame 1 is fixed by bolts, the cable is placed into the bottom frame 1, at the upper side position of the guide roller 8. When installing the outer frame 2, by pressing the guide roller 8, the spring 12 located in the guide columns 10 on both sides is compressed, so that the guide roller 8 is compressed towards the bottom plate 9, and then the outer frame 2 is buckled. The compressed guide roller 8 can be installed corresponding to the positions of the notches 14 on both sides of the outer frame 2, realizing the installation of the whole device.

[0018] During specific use, as shown in Figures 1-4 the figure, both sides of the cable are arranged along the first frame plate 3 and the second frame plate 4. At the connection of the first frame plate 3 and the inclined frame plate 5, and at the connection of the second frame plate 4 and the inclined frame plate 5, through the arrangement of the scratch-proof roller 6, the problem of difficult damage caused by direct contact with the obtuse corner during the use and pulling of the cable is avoided; when the cable is pulled after being arranged, the cable drives the guide roller 8 to be compressed towards the bottom plate 9 after being pulled. After the pulling is finished, the spring 12 rebounds, pulling back part of the cable, so that the construction personnel can feel whether the cable is too tense when arranged in the cable tray, and the part of the cable pulled back by the rebound ensures that there is a certain margin at the turning of the cable to avoid the problem of the cable being scratched due to being too tight at the turning.
