Description

Technical Field

[0001] The utility model relates to the field of cable installation, in particular to a cable bridge which is easy to install. Background Art

[0002] A cable tray is a bracket that is suspended and installed on the roof to support cables. The cable tray is made of metal and has strong hardness in supporting cables. The same cable tray can support multiple cables at the same time, and has the advantages of convenient installation and operation. However, when installing the cable tray, if obstacles are encountered, the installation direction of the cable tray needs to be changed. Especially in ceiling operations, the cable tray needs to be bent up / down, or a connection bridge with an inclined angle needs to be customized to facilitate bypassing obstacles such as beams, which in turn affects the installation progress of the cable tray. Utility Model Content

[0003] The purpose of the present invention is to provide a cable tray that is easy to install, so as to solve the problems raised in the above background technology.

[0004] In order to solve the above technical problems, the present invention provides the following technical solutions: a cable tray that is easy to install, comprising two frames with the same structure, the two adjacent ends of the frames being hinged, one end of the frames being symmetrical and integrally provided with two first hinge plates, the first hinge plates being close to the outer wall of the frames, the other end of the frames being symmetrical and integrally provided with two second hinge plates, the second hinge plates being close to the inner wall of the frames, the first hinge plates and the second hinge plates being arc-shaped at the ends away from the frames, and both being provided with mounting holes, the first hinge plates and the second hinge plates on the same side between the two frames being fixed by a fixing part, the fixing part comprising a bolt and a hexagonal nut, the outer wall diameter of the bolt rod being equal to the inner wall diameter of the mounting hole.

[0005] Furthermore, two dust-proof mechanisms are symmetrically arranged at the upper and lower hinges of the two frames, and the dust-proof mechanism located at the top of the frame includes two connecting frames, a U-shaped frame and a dust cover for covering the hinge. The dust cover is elastic, and the two connecting frames are fixedly installed on the opposite sides of the two frames respectively. The U-shaped frame is arranged between the two connecting frames, and the two ends are respectively fixed to the outer walls of the two first hinge plates by rivets. The U-shaped frame is aligned with the center of the mounting hole. The dust cover covers the hinge of the two frames and is fixed to the top of the U-shaped frame and the top of the two connecting frames by rivets.

[0006] Furthermore, a sliding groove is horizontally provided on the outer wall of the first hinged plate, and a through hole is provided on the side wall of the U-shaped frame. A connecting rod is interference-fitted in the through hole, and the end of the connecting rod close to the first hinged plate extends into the sliding groove on the same side, and the outer wall of the connecting rod is in contact with the inner wall of the sliding groove and is slidably connected.

[0007] Furthermore, the dust cover is a corrugated plate with telescopic function.

[0008] Furthermore, the corrugated plate is made of stainless steel.

[0009] The beneficial effects achieved by the utility model are:

[0010] The hinged connection makes the cable tray more flexible during installation. Since the hinge allows angle adjustment within a certain range, it can more easily adapt to changes in the on-site environment, simplify the installation steps and improve installation efficiency.

[0011] By providing a dustproof mechanism at the hinge of the two frames, dust and other impurities can be effectively prevented from entering the hinge, thereby avoiding possible damage to the cable due to long-term direct contact with the external environment.

[0012] The U-shaped frame and dust cover at the bottom provide support for the cable, which helps reduce sagging or twisting of the cable during use, thereby further protecting the integrity and performance of the cable.

[0013] By setting the slide groove and the connecting rod, the U-shaped frame can move flexibly relative to each other when the frame is bent. This design ensures that the frame will not be limited by the U-shaped frame during the bending process, thereby improving the flexibility and adaptability of the overall mechanism.

[0014] The outwardly protruding arc of the U-shaped frame away from the side wall section of the dust cover on the same side provides a larger contact area when the U-shaped frame abuts the second hinge plate, and improves the sliding performance of the contact surface of the U-shaped frame with the first hinge plate when moving.

[0020] The present invention will be further described below with reference to the accompanying drawings.

[0021] like Figure 1-3 As shown, the utility model discloses a cable tray that is easy to install, comprising: two frames 1 with the same structure, and the adjacent ends of the two frames 1 are hinged. The hinged connection makes the cable tray more flexible during installation. Since the hinge allows angle adjustment within a certain range, it can more easily adapt to changes in the on-site environment, simplify the installation steps, and improve installation efficiency.

[0022] Specifically, such as Figure 2-3 As shown, one end of the frame body 1 is symmetrical and integrally provided with two first hinge plates 11, the first hinge plate 11 is close to the outer wall of the frame body 1, and the other end of the frame body 1 is symmetrical and integrally provided with two second hinge plates 12, the second hinge plate 12 is close to the inner wall of the frame body 1, and the first hinge plate 11 and the second hinge plate 12 are both arranged in an arc shape at one end away from the frame body 1, and are both provided with mounting holes 13. The first hinge plate 11 and the second hinge plate 12 on the same side of the two frames 1 are fixed by a fixing member 2, and the fixing member 2 includes a bolt 21 and a hexagonal nut 22. The rod of the bolt 21 is threadedly connected to the inner wall of the hexagonal nut 22. The outer wall diameter of the rod of the bolt 21 is equal to the inner wall diameter of the mounting hole 13, and the length of the rod of the bolt 21 is greater than the length from the inner wall of the second hinge plate 12 to the outer wall of the hexagonal nut 22;

[0023] Based on the above structure, Figure 2-3 As shown, during installation, the inner wall of the first hinged plate 11 on the same side at the opposite end of the two frames 1 is fitted with the outer wall of the second hinged plate 12 on the same side, and the two mounting holes 13 on the same side are aligned. Then, a bolt 21 is passed through the two common mounting holes 13 and threadedly connected with the hexagonal nut 22 to fix the first hinged plate 11 and the second hinged plate 12 on the same side. The exposed rod of the bolt 21 is used to provide a hanging point for the ceiling operation.

[0024] Furthermore, the development state of the hinge of the two bridges causes the cables to be exposed to the outside, which not only causes a lot of dust to adhere to them, but also causes different degrees of damage to the cables due to long-term direct contact with the external environment. In order to solve the above problems, Figure 3As shown, two dust-proof mechanisms 3 are symmetrically arranged at the upper and lower parts of the hinge of the two frames 1. The dust-proof mechanism 3 located at the top of the frame 1 includes two connecting frames 31, a U-shaped frame 32 and a dust cover 33 for covering the hinge. The dust cover 33 is elastic. The two connecting frames 31 are fixedly installed on the opposite sides of the two frames 1 respectively. The U-shaped frame 32 is arranged between the two connecting frames 31, and the two ends are fixed to the outer walls of the two first hinge plates 11 by rivets. The U-shaped frame 32 is aligned with the center of the mounting hole 13. The dust cover 33 covers the hinge of the two frames 1 and is fixed to the top of the U-shaped frame 32 and the top of the two connecting frames 31 by rivets respectively.

[0025] When the frame 1 at the front side needs to be bent downward to a certain angle, the U-shaped frame 32 will rotate with the center of the bolt 21 as the center of rotation. Since the dust cover 33 is elastic, the dust cover 33 between the upper U-shaped frame 32 and the rear connecting frame 31 will stretch accordingly. The dust cover 33 between the upper U-shaped frame 32 and the front connecting frame 31 and the dust cover 33 at the bottom will shrink. The dust cover 33 keeps covering the hinge of the two frames 1. Conversely, when the frame 1 at the front side needs to be bent upward to a certain angle, the dust cover 33 between the lower U-shaped frame 32 and the rear connecting frame 31 will stretch accordingly.

[0026] At the same time, the U-shaped frame 32 and the dust cover 33 at the bottom play a certain supporting role for the cable.

[0027] Further, such as Figure 3-4 As shown, in order to prevent the U-shaped frame from limiting the bending of the frame body, a sliding groove 111 is horizontally provided on the outer wall of the first hinge plate 11, and a through hole 321 is provided on the side wall of the U-shaped frame 32. A connecting rod 34 is interference-fitted into the through hole 321. The end of the connecting rod 34 close to the first hinge plate 11 extends into the sliding groove 111 on the same side. The outer wall of the connecting rod 34 fits with the inner wall of the sliding groove 111 and is slidably connected. The cross-section of the side wall of the U-shaped frame 32 away from the dust cover 33 on the same side is an outwardly protruding arc setting;

[0028] When the frame 1 located at the front side is bent, an angle is formed between the two frames 1. The first hinge plate 11 at the angle drives the U-shaped frame 32 to approach the second hinge plate 12 and abut against it. The second hinge plate 12 generates a reaction force on the U-shaped frame 32 in the direction of the front frame 1. The U-shaped frame 32 is driven by the force to drive the connecting rod 34 to slide along the slide groove 111, thereby preventing the U-shaped frame 32 from limiting the bending of the frame 1. The dust cover 33 on the same side stretches / contracts with the movement of the U-shaped frame 32.

[0029] Further, such as Figure 5 As shown, the dust cover 33 is a corrugated plate with telescopic function.

[0030] Furthermore, in order to increase the emphasis of the corrugated plate, the corrugated plate is made of stainless steel.

[0031] The above are only preferred specific implementation methods of the present invention, but the protection scope of the present invention is not limited to them. Any technician familiar with the technical field can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention within the technical scope disclosed by the present invention, and they should be covered by the protection scope of the present invention.
