[0003] The width of cable trays used in building construction is fixed, and the upper limit of the number of wires they can support and fix is ​​also fixed. However, the number of wires that need to be supported and fixed varies in different building construction scenarios. Fixed-model cable trays are difficult to adapt to different building construction needs, which reduces the practicality of the cable trays. Utility Model Content

[0004] This utility model proposes a power cabling device for building construction to address the problem that the number of wires that need to be supported and fixed varies in different building construction scenarios, and that fixed-model cable trays are difficult to adapt to different building construction needs, which reduces the practicality of the cable trays.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a power wiring device for building construction, comprising two crossbars, an adjustment device disposed between the two crossbars, the adjustment device comprising a plurality of sleeves, the plurality of sleeves being evenly disposed between the two crossbars, a connecting rod symmetrically slidably connected to the inner wall of the sleeve, the ends of the two connecting rods being respectively fixedly connected to the inner wall of the two crossbars, a first extension block symmetrically fixedly connected to the bottom of the sleeve, a threaded cylinder fixedly connected to the inner wall of the two extension blocks, a threaded rod symmetrically threadedly connected to the inner wall of the threaded cylinder, a second extension block disposed on the outer surface of the threaded rod, one side of the second extension block being fixedly connected to one side of the connecting rod, a support rod disposed at the top of the crossbar, an auxiliary device disposed between the support rod and the crossbar, and a mounting plate fixedly connected to one end of the support rod.

[0006] The effect achieved by the above components is as follows: by setting up a sleeve and two connecting rods, under the action of the threaded rod, rotating the threaded rod will cause the threaded rod to extend and retract on the inner wall of the threaded sleeve. During the extension and retraction of the threaded rod, it will drive the connecting rod connected to the second extension block to slide on the inner wall of the sleeve. During the movement of the connecting rod, it will drive the crossbar to move synchronously. When the threaded rod stops rotating, the threaded rod and the threaded rod can fix the sleeve and the connecting rod, thus facilitating the adjustment of the width of the cable tray according to the actual needs of building construction, so that it can be adapted to different building construction needs and improve the practicality of the cable tray.

[0007] Preferably, a bearing is fixedly connected to the outer surface of the threaded rod, and the outer surface of the bearing is fixedly connected to the inner wall of the second extension block.

[0008] The effect achieved by the above components is that by setting bearings, the friction between the threaded rod and the second extension block can be reduced when rotating the threaded rod, making it easier to rotate the threaded rod.

[0009] Preferably, each of the two threaded rods has an operating block fixedly connected to one of its far ends, and the outer surface of the operating block is provided with a protrusion.

[0010] The effect achieved by the above components is as follows: by setting the operating block, rotating the operating block can drive the threaded rod to rotate. At the same time, the outer surface of the operating block is provided with protrusions, which can effectively increase the friction of the outer surface of the operating block and have an anti-slip effect when rotating the operating block.

[0011] Preferably, a slider is fixedly connected to the inner wall of the sleeve, and the outer surface of the slider is slidably connected to the inner walls of the two connecting rods.

[0012] The effect achieved by the above components is as follows: by setting the slider, when the connecting rod moves under the action of the threaded rod, it will drive the connecting rod to slide synchronously on the outer surface of the slider, which can play a limiting role between the sleeve and the connecting rod, making the connecting rod more stable during the movement.

[0013] Preferably, each of the two first extension blocks is fixedly connected to a screw hole block on the side that is far apart from each other, and the inner wall of the screw hole block is threaded with a bolt.

[0014] The effect achieved by the above components is as follows: by setting the bolt and rotating the bolt so that one end of the bolt abuts against one side of the connecting rod, the sleeve and the connecting rod can be auxiliaryly fixed, which can reduce the fixing pressure of the threaded rod and threaded cylinder on the connecting rod and the sleeve, and further prevent the connecting rod from sliding on the inner wall of the sleeve.

[0016] The effect achieved by the above components is as follows: by setting a threaded pin, inserting the threaded pin into the inner wall of the round hole block, one side of the round hole block abuts against one side of the crossbar, and then putting a nut on one end of the threaded pin, rotating the nut so that one side of the nut abuts against one side of the round hole block, the round hole block and the crossbar can be fixed, thereby providing auxiliary fixation between the support rod and the crossbar, making the connection between the support rod and the crossbar more stable.

[0017] Preferably, a reinforcing block is fixedly connected to one side of the auxiliary block, and one side of the reinforcing block is fixedly connected to one side of the circular hole block. The cross-section of the reinforcing block is triangular.

[0018] The effect achieved by the above components is that by setting up triangular reinforcing blocks, the stability of the triangle can be used to provide auxiliary support and reinforcement between the support rod and the crossbar, thereby improving the overall stability of the cable tray.

[0019] Preferably, a U-shaped block is symmetrically fixedly connected to the top of the crossbar, and the outer surface of the circular hole block is inserted into the inner wall of the U-shaped block.

[0020] The effect achieved by the above components is as follows: by setting up a U-shaped block and inserting the round hole block into the inner wall of the U-shaped block, the round hole block and the crossbar can be positioned, which facilitates the subsequent quick installation of the round hole block and the crossbar.

[0029] Example 1, referring to Figures 1-3 As shown, this embodiment discloses a power wiring device for building construction, including two horizontal bars 1, with an adjusting device 2 between the two horizontal bars 1. The adjusting device 2 includes several sleeves 22, which are evenly arranged between the two horizontal bars 1. Connecting rods 21 are symmetrically slidably connected to the inner walls of the sleeves 22. The ends of the two connecting rods 21 that are far apart are respectively fixedly connected to the inner walls of the two horizontal bars 1. First extension blocks 23 are symmetrically fixedly connected to the bottom of the sleeves 22. Threaded cylinders 24 are fixedly connected to the inner walls of the two extension blocks. Threaded rods 25 are symmetrically threaded to the inner walls of the threaded cylinders 24. Second extension blocks 26 are provided on the outer surface of the threaded rods 25. One side of the second extension block 26 is fixedly connected to one side of the connecting rod 21. A support rod 3 is provided at the top of the horizontal bars 1. The support rod 3 and the horizontal bar 1 are connected to each other. An auxiliary device 4 is provided between the rods 1. One end of the support rod 3 is fixedly connected to the mounting plate 5. By setting up the sleeve 22 and two connecting rods 21, under the action of the threaded rod 25, the threaded rod 25 is rotated and will extend and retract on the inner wall of the threaded cylinder 24. During the extension and retraction process, the threaded rod 25 will drive the connecting rod 21 connected to the second extension block 26 to slide on the inner wall of the sleeve 22. During the movement of the connecting rod 21, it will drive the crossbar 1 to move synchronously. When the threaded rod 25 stops rotating, the threaded rod 25 and the connecting rod 21 can be fixed together, so as to facilitate the adjustment of the width of the cable tray according to the actual needs of the building construction, so that it can be adapted to different building construction needs and improve the practicality of the cable tray.

[0030] Reference Figure 2 and Figure 3As shown, a bearing 27 is fixedly connected to the outer surface of the threaded rod 25. The outer surface of the bearing 27 is fixedly connected to the inner wall of the second extension block 26. By setting the bearing 27, the friction between the threaded rod 25 and the second extension block 26 can be reduced when rotating the threaded rod 25, making it easier to rotate the threaded rod 25. An operating block 28 is fixedly connected to the ends of the two threaded rods 25 that are far apart. The outer surface of the operating block 28 is provided with protrusions. By setting the operating block 28, rotating the operating block 28 can drive the threaded rod 25 to rotate. At the same time, the protrusions on the outer surface of the operating block 28 can effectively increase the friction on the outer surface of the operating block 28, which has an anti-slip effect when rotating the operating block 28.

[0031] Reference Figure 2 and Figure 3 As shown, a slider 29 is fixedly connected to the inner wall of the sleeve 22. The outer surface of the slider 29 is slidably connected to the inner walls of the two connecting rods 21. By setting the slider 29, when the connecting rod 21 moves under the action of the threaded rod 25, it will drive the connecting rod 21 to slide synchronously on the outer surface of the slider 29, which can limit the movement between the sleeve 22 and the connecting rod 21, making the connecting rod 21 more stable during movement. A screw hole block 210 is fixedly connected to the side of the two first extension blocks 23 that are far apart. The inner wall of the screw hole block 210 is threaded with a bolt 211. By setting the bolt 211, rotating the bolt 211 will cause one end of the bolt 211 to abut against one side of the connecting rod 21, which can provide auxiliary fixation between the sleeve 22 and the connecting rod 21, reduce the fixing pressure of the threaded rod 25 and the threaded sleeve 24 on the connecting rod 21 and the sleeve 22, and further prevent the connecting rod 21 from sliding on the inner wall of the sleeve 22.

[0032] Reference Figure 4 and Figure 5 As shown, the auxiliary device 4 includes two auxiliary blocks 41. One side of each auxiliary block 41 is symmetrically fixed to both sides of the support rod 3. One end of each auxiliary block 41 is fixedly connected to a round hole block 42. One side of the round hole block 42 abuts against one side of the crossbar 1. A threaded pin 43 is inserted into the inner wall of the round hole block 42. One end of the threaded pin 43 is fixedly connected to one side of the crossbar 1. A nut 44 is threaded onto the outer surface of the threaded pin 43. By setting the threaded pin 43, inserting it into the inner wall of the round hole block 42, and abutting one side of the round hole block 42 against one side of the crossbar 1, and then fitting the nut 44 onto one end of the threaded pin 43, rotating the nut 44 so that one side of the nut 44 abuts against one side of the round hole block 42, the round hole block 42 and the crossbar 1 can be fixed, thereby providing auxiliary fixation between the support rod 3 and the crossbar 1, making the connection between the support rod 3 and the crossbar 1 more stable.

[0033] Reference Figure 4 and Figure 5As shown, a reinforcing block 45 is fixedly connected to one side of the auxiliary block 41, and one side of the reinforcing block 45 is fixedly connected to one side of the round hole block 42. The cross section of the reinforcing block 45 is triangular. By setting the triangular reinforcing block 45, the stability of the triangle can be used to provide auxiliary support and reinforcement between the support rod 3 and the crossbar 1, thereby improving the overall stability of the cable tray. A U-shaped block 46 is symmetrically fixedly connected to the top of the crossbar 1. The outer surface of the round hole block 42 is inserted into the inner wall of the U-shaped block 46. By setting the U-shaped block 46 and inserting the round hole block 42 into the inner wall of the U-shaped block 46, the round hole block 42 and the crossbar 1 can be positioned, thereby facilitating the subsequent quick installation between the round hole block 42 and the crossbar 1.

[0034] Working principle: When the distance between the two crossbars 1 needs to be adjusted, rotate the two operating blocks 28 on both sides respectively. The operating blocks 28 will drive the threaded rod 25 to extend and retract within the inner wall of the threaded cylinder 24. Under the limit of the slider 29, the threaded rod 25 will drive the connecting rod 21 connected to the second extension block 26 to slide within the inner wall of the sleeve 22. During the movement of the connecting rod 21, it will drive the crossbars 1 to move synchronously until the two crossbars 1 reach the appropriate position. Then rotate the bolt 211 so that one end of the bolt 211 abuts against one side of the connecting rod 21, thus enabling the sleeve 22 and the connecting rod to be adjusted. Auxiliary fixing is performed between 21 to complete the adjustment; when it is necessary to fix the support rod 3 and the crossbar 1, insert the threaded pin 43 into the inner wall of the round hole block 42, the round hole block 42 is inserted into the inner wall of the U-shaped block 46, and then put the nut 44 on one end of the threaded pin 43. Rotate the nut 44 so that one side of the nut 44 abuts against one side of the round hole block 42, which can fix the round hole block 42 and the crossbar 1, and thus provide auxiliary fixing between the support rod 3 and the crossbar 1. At the same time, with the joint action of the triangular reinforcing block 45, the connection between the support rod 3 and the crossbar 1 is more stable.
