[0001] This application relates to the technical field of cable laying, specifically a cable laying device for building construction. Background Art

[0002] The cable tray system is an important type of product in the manufacturing industry and is the main equipment used to standardize and protect the safety of cables and power transmission lines in various infrastructure projects.

[0003] The existing patent (publication number: CN205319625U) discloses a ladder-type straight-through tray, including a cross arm. There are ladder sides on both sides of the cross arm. One end of the ladder side is provided with a tongue, and the other end is provided with a mounting hole. The tongue is provided with a mounting hole that matches the mounting hole on the ladder side. The ladder-type straight-through tray provided by the utility model has high installation efficiency, omits the tray connection plate, and has low cost.

[0004] For the ladder-type straight-through tray pointed out in the above patent, during actual use, when encountering obstacles, it is still necessary to cut the tray to form slopes and bends, resulting in a more cumbersome installation process. At the same time, when using the above tray, it needs to be connected through bolts and nuts in cooperation with the mounting holes, and multiple bolts are required for connection during the connection process, thus making the time consumed during the installation process relatively long and resulting in low installation efficiency. Summary of the Utility Model

[0005] In view of the deficiencies of the prior art, this application provides a cable laying device for building construction, which has the advantages of being easy to disassemble, etc., and solves the problems that when the tray encounters obstacles during actual use, it is still necessary to cut the tray to form slopes and bends, resulting in a more cumbersome installation process. At the same time, when using the above tray, it needs to be connected through bolts and nuts in cooperation with the mounting holes, and multiple bolts are required for connection during the connection process, thus making the time consumed during the installation process relatively long and resulting in low installation efficiency.

[0006] To achieve the above object, this application provides the following technical solution: A cable laying device for building construction, including a first tray and a fixing frame. One end of the first tray is fixedly connected to a rectangular rubber expansion tube, and the end of the rectangular rubber expansion tube away from the first tray is fixedly connected to a second tray.

[0007] Mounting columns are rotatably connected to both sides of the first tray and the second tray. A plurality of mounting holes are linearly and arrayedly distributed inside the fixing frame. Two of the plurality of mounting holes are internally slidably connected to bolts, and one end of each of the two bolts penetrates through the mounting hole and is threadedly connected to the inside of the mounting column.

[0008] Through the above solution, a rectangular rubber expansion pipe is fixedly connected between the first bridge and the second bridge. During actual use, the rectangular rubber expansion pipe can be bent according to actual needs without cutting the first bridge and the second bridge. At the same time, during use, align the connection block with the installation groove, and then insert the connection block into the installation groove. During the insertion of the connection block, the positioning post will be squeezed, causing the positioning post to move towards the installation frame until the positioning hole opened in the connection block corresponds to the positioning post. At this time, the positioning post is no longer stressed, and the limiting plate will move under the push of the spring, and then drive the positioning post into the positioning hole to lock the connection block, thus completing the connection.

[0009] Further, two connection blocks distributed in a mirror image are fixedly connected to one end of the first bridge, and positioning holes are opened in both of the two connection blocks.

[0010] Through the above solution, the positioning hole is used to position the connection block during use.

[0011] Further, two installation grooves distributed in a mirror image and corresponding to the connection blocks are opened in the second bridge, and an installation frame is fixedly connected to the position of the inner wall of the second bridge corresponding to the installation groove.

[0012] Through the above solution, the installation frame is used to install the positioning post and limit the position of the positioning post.

[0013] Further, a positioning post corresponding to the positioning hole is slidably connected inside the installation frame, and one end of the positioning post penetrates through the second bridge and extends into the installation groove.

[0014] Through the above solution, the cooperation between the positioning post and the positioning hole can lock the connection block.

[0015] Further, a limiting plate is fixedly connected to one end of the positioning post, and a spring is fixedly connected to the surface of the limiting plate. The end of the spring away from the limiting plate abuts against the inner wall of the installation frame.

[0016] Through the above solution, when the positioning post moves during use, it will drive the limiting plate to move, and then the limiting plate will drive the spring to deform.

[0017] Further, a group of connection frames are fixedly connected inside both the first bridge and the second bridge, and each group consists of three connection frames distributed in a straight line array.

[0018] Through the above solution, when in use, the cable is passed through the connection frame, and the connection frame can limit the cable.

[0019] Further, a pressing plate is slidably connected inside the connecting frame. Both sides of the pressing plate are in contact with the inner wall of the connecting frame. A threaded column is threadedly connected inside the upper end of the connecting frame. The lower end of the threaded column penetrates through the connecting frame and is rotatably connected to the surface of the pressing plate. The upper end of the threaded column is fixedly connected with a rotating handle.

[0020] Through the above solution, when in use, rotate the rotating handle. The rotation of the rotating handle will drive the threaded rod to rotate, and then the threaded rod will move downward, thereby driving the pressing plate to move downward.

[0021] Compared with the prior art, the technical solution of the present application has the following beneficial effects:

[0022] In this cable laying device for building construction, a rectangular rubber expansion pipe is fixedly connected between the first bridge and the second bridge. During actual use, the rectangular rubber expansion pipe can be bent according to actual needs without cutting the first bridge and the second bridge. At the same time, when in use, align the connecting block with the installation groove, and then insert the connecting block into the installation groove. During the insertion of the connecting block, the positioning column will be squeezed, causing the positioning column to move towards the installation frame. Until the positioning hole opened inside the connecting block corresponds to the positioning column, the positioning column is no longer stressed. At this time, the limiting plate will move under the push of the spring, and then drive the positioning column into the positioning hole to lock the connecting block, and the connection can be completed. The connection process is relatively simple and takes less time, making the installation efficiency of this device relatively high. BRIEF DESCRIPTION OF THE DRAWINGS

One end of the first bridge 1 is fixedly connected with a rectangular rubber expansion pipe 2. The end of the rectangular rubber expansion pipe 2 far from the first bridge 1 is fixedly connected with a second bridge 3. Installation columns 10 are rotatably connected to both sides of the first bridge 1 and the second bridge 3. A plurality of installation holes 13 arranged in a linear array are opened inside the fixed frame 12. Two of the plurality of installation holes 13 are internally slidably connected with bolts 11. One end of each of the two bolts 11 penetrates through the installation hole 13 and is threadedly connected to the inside of the installation column 10.

[0033] Please refer to Figure 2 and Figure 3 , two mirror-image distributed connecting blocks 9 are fixedly connected to one end of the first bridge 1. Positioning holes 18 are opened inside the two connecting blocks 9. The positioning holes 18 are used to position the connecting blocks 9 during use. Two mirror-image distributed installation grooves 4 corresponding to the connecting blocks 9 are opened inside the second bridge 3. Installation frames 5 are fixedly connected to the positions corresponding to the installation grooves 4 on the inner wall of the second bridge 3. The installation frames 5 are used to install the positioning columns 7 and limit the positions of the positioning columns 7. Positioning columns 7 corresponding to the positioning holes 18 are slidably connected inside the installation frames 5. One end of the positioning column 7 penetrates through the second bridge 3 and extends into the installation groove 4. The cooperation between the positioning column 7 and the positioning hole 18 can lock the connecting block 9. A limiting plate 8 is fixedly connected to one end of the positioning column 7. A spring 6 is fixedly connected to the surface of the limiting plate 8. The end of the spring 6 far from the limiting plate 8 abuts against the inner wall of the installation frame 5. When in use, when the positioning column 7 moves, it will drive the limiting plate 8 to move, and then the limiting plate 8 will drive the spring 6 to deform.

[0034] Please refer to Figure 1 , Figure 2and Figure 3 Inside the first cable tray 1 and the second cable tray 3, a set of connecting frames 14 are fixedly connected. Each set consists of three connecting frames 14 arranged in a linear array. During use, the cable is passed through the inside of the connecting frame 14. The connecting frame 14 can limit the cable. A pressing plate 15 is slidably connected inside the connecting frame 14. Both sides of the pressing plate 15 are in contact with the inner wall of the connecting frame 14. A threaded column 16 is threadedly connected inside the upper end of the connecting frame 14. The lower end of the threaded column 16 penetrates through the connecting frame 14 and is rotatably connected to the surface of the pressing plate 15. The upper end of the threaded column 16 is fixedly connected with a rotating handle 17. During use, the rotating handle 17 is rotated. The rotation of the rotating handle 17 will drive the threaded column 16 to rotate, and then the threaded column 16 will move downward, thereby driving the pressing plate 15 to move downward.

[0035] In this embodiment, a rectangular rubber expansion pipe 2 is fixedly connected between the first cable tray 1 and the second cable tray 3. During actual use, the rectangular rubber expansion pipe 2 can be bent according to actual needs without cutting the first cable tray 1 and the second cable tray 3. At the same time, during use, the connecting block 9 is aligned with the installation groove 4, and then the connecting block 9 is inserted into the installation groove 4. During the insertion of the connecting block 9, the positioning column 7 will be squeezed, causing the positioning column 7 to move towards the installation frame 5. Until the positioning hole 18 opened inside the connecting block 9 corresponds to the positioning column 7, the positioning column 7 is no longer stressed. At this time, the limiting plate 8 will move under the push of the spring 6, and then drive the positioning column 7 into the positioning hole 18 to lock the connecting block 9, and the connection can be completed. The connection process is relatively simple and takes less time, making the installation efficiency of this device relatively high.

[0036] The working principle of the above embodiment is as follows:

[0037] First, install the fixing frame 12 on the first laying device on the ceiling, then install the fixing frame 12 on the other laying device on the ceiling, then align the two connecting blocks 9 on the first cable tray 1 in the other laying device with the installation groove 4 inside the second cable tray 3 in the first laying device, and then insert the connecting block 9 into the installation groove 4. During the insertion of the connecting block 9, the positioning column 7 will be squeezed, causing the positioning column 7 to move towards the installation frame 5. Until the positioning hole 18 opened inside the connecting block 9 corresponds to the positioning column 7, the positioning column 7 is no longer stressed. At this time, the limiting plate 8 will move under the push of the spring 6, and then drive the positioning column 7 into the positioning hole 18 to lock the connecting block 9, and the connection can be completed. Then insert the cable into the installation frame 5, and then rotate the rotating handle 17. The rotation of the rotating handle 17 will drive the threaded column 16 to rotate, and then the threaded column 16 will move downward, thereby driving the pressing plate 15 to move downward to press the cable tightly, so as to limit the cable.
