[0006] By adopting the above technical scheme, the construction workers bring the two trough boxes close together so that the ends on the two trough boxes fit together, and make the multiple fixing holes circumferentially spaced on the ends of the two trough boxes face each other, and then rotate the two trough boxes with the center of the circle surrounded by the multiple fixing holes as the center point, so as to adjust the bending angle between the two trough boxes. After adjusting to the required angle, fit the sealing plate to the end head so that the center of the circle surrounded by the thread holes on the sealing plate coincides with the center of the circle surrounded by the multiple fixing holes on the end head, and then thread multiple positioning bolts into different thread holes and thread them into the fixing holes respectively, so as to position the two trough boxes at the current angle, and then close the bottom gap between adjacent trough boxes through the closing mechanism, and then carry out subsequent cable laying work.

During the adjustment process, the first corrugated plate bends and contracts accordingly, and then the first connection box is attached to one of the trough boxes, and the second connection box is attached to the other trough box.

[0036] Reference Figure 1 , Figure 2The trough box 1 is a box body with a hollow interior and an open upper end. The end head 2 is respectively installed with one on both sides of the end of the length direction of the trough box 1. The two end heads 2 are each provided with a first center hole 22. The first center holes 22 on the two end heads 2 are directly opposite to each other. The end heads 2 are provided with a plurality of fixing holes 21 circumferentially spaced around the first center hole 22; a locking mechanism 3 is installed on the end heads 2. The locking mechanism 3 is used to connect and position the end heads 2 on adjacent trough boxes 1. The locking mechanism 3 includes a sealing plate 31 and a plurality of positioning bolts 32. The sealing plate 31 abuts against the end heads 2. The sealing A second center hole 312 is provided on the plate 31, and a plurality of thread holes 311 are provided on the sealing plate 31 with the second center hole 312 as the center and circumferentially spaced apart. The diameter of a circle formed by the plurality of thread holes 311 is the same as the diameter of a circle formed by the plurality of fixing holes 21. A rotating shaft 5 is inserted into the second center hole 312 for sliding and rotation. The rotating shaft 5 is inserted into the first center hole 22 for sliding and rotation. A plurality of positioning bolts 32 are respectively threadedly inserted into a plurality of different thread holes 311, and the positioning bolts 32 pass through the thread holes 311 and are threadedly inserted into the corresponding fixing holes 21 on the end head 2. The construction personnel bring the two trough boxes 1 close to each other, so that the end heads 2 on the two trough boxes 1 fit together, and the first center holes 22 on the end heads 2 on the two trough boxes 1 are connected, and then the rotating shaft 5 is inserted into the first center hole 22 on the end heads 2 on the two trough boxes 1. The rotating shaft 5 can be used as the rotating shaft when the two trough boxes 1 rotate to adjust the angle, thereby preventing the two trough boxes 1 from shifting when the construction personnel rotate the two trough boxes 1 to adjust the angle, and improving the stability and convenience of the construction personnel when adjusting the angle of the two trough boxes 1; after adjusting the angle between the two trough boxes 1 according to the required bending angle of the cable, the construction personnel move the sealing plate 31 so that the rotating shaft 5 is inserted into the second center hole 312 on the sealing plate 31, and drive the sealing plate 31 to abut against the end head 2, so that the multiple thread holes 311 on the sealing plate 31 are respectively aligned with the thread holes 311 on the end head 2 The multiple fixing holes 21 are respectively connected. During the installation of the sealing plate 31, the rotating shaft 5 is used to position and guide the installation of the sealing plate 31, which improves the convenience of the construction workers in installing the sealing plate 31; finally, the construction workers thread the multiple positioning bolts 32 into the multiple thread holes 311 respectively, and make the positioning bolts 32 threaded into the fixing holes 21 connected with the thread holes 311. The positioning bolts 32 can limit the rotation of the two trough boxes 1 and position the two trough boxes 1 at the current angle. Then the construction workers can lay the cable into the trough box 1, so that the angle of the two trough boxes 1 is adapted to the required bending angle of the cable. The construction workers can adaptively adjust the angle between the two trough boxes 1 according to the required bending angle of the cable at the construction site, thereby effectively improving the applicability of the cable tray to the required bending angle of cable laying at the construction site.

The closing mechanism 4 includes a first connecting box 41, a second connecting box 42, a first corrugated plate 43 and a pulling assembly 44. The first connecting box 41 and the second connecting box 42 are both hollow boxes with open upper ends. The inner diameters of the first connecting box 41 and the second connecting box 42 are the same as the outer diameter of the trough box 1. One end of the first corrugated plate 43 is installed on the first connecting box 41, and the other end of the first corrugated plate 43 is installed on the second connecting box 42. In this embodiment, the first corrugated plate 43 is a stainless steel corrugated plate; a group of pulling assemblies 44 are respectively installed on both sides of the length direction of the first connecting box 41, and the pulling assemblies 44 are respectively installed on the length direction of the second connecting box 42.

The pulling component 44 includes a telescopic rod 441, a pulling block 442 and a pulling bolt 443. The telescopic rod 441 is hingedly installed on the first connecting box 41 or the second connecting box 42. The length of the telescopic rod 441 is retractable. In this embodiment, the telescopic rod 441 includes a sleeve, a screw and a mounting seat. The sleeve is hingedly installed on the first connecting box 41 or the second connecting box 42. The screw is threadedly penetrated on the inner wall of the sleeve. The mounting seat is rotatably installed on the screw. The pulling block 442 is hingedly installed on the mounting seat. The pulling bolt 443 is threadedly penetrated on the pulling block 442. The pulling bolt 443 is used to be threadedly penetrated into the thread hole 311 and the fixing hole 21.

[0038] After the construction personnel have positioned the two trough boxes 1, they rotate the first connection box 41 and the second connection box 42 to adjust the angle between the first connection box 41 and the second connection box 42 to the angle between the two trough boxes 1. During the adjustment process, the first corrugated plate 43 rotates with the first connection box 41 and the second connection box 42 to bend and stretch. Then the construction personnel buckle the first connection box 41 and the second connection box 42 to the bottom of the two trough boxes 1 respectively, so that the first connection box 41, the second connection box 42 and the first corrugated plate 43 close the gap at the bend of the two trough boxes 1, and then rotate the screw to adjust the telescopic The length of the rod 441 is adjusted, and the telescopic rod 441 is rotated to move the pulling block 442 to the closing plate 31. The pulling bolt 443 on the pulling block 442 is opposite to one of the thread holes 311 on the closing plate 31. The pulling bolt 443 on the pulling block 442 is screwed into the thread hole 311, and the first connecting box 41 or the second connecting box 42 can be pulled by the telescopic rod 441, so that the first connecting box 41 and the second connecting box 42 remain in a state of being fitted on the trough box 1, and the gap at the bending of the two trough boxes 1 can be quickly and conveniently closed, effectively improving the protection effect of the cable at the bending of the two trough boxes 1.

[0039] Reference Figure 1 , Figure 4, the connecting mechanism 6 is installed on the trough box 1, and the connecting mechanism 6 is used to connect the end of the trough box 1 away from the end head 2 with the adjacent trough box 1. The connecting mechanism 6 includes a connecting groove 61, a connecting bolt 62 and an adjusting bolt 63. The connecting groove 61 is a trough body with a hollow interior and an open upper end. The outer diameter of the connecting groove 61 is the same as the inner diameter of the trough box 1. The two ends of the side wall on the same side of the length direction of the connecting groove 61 are respectively provided with a locking hole 611 and a strip hole 612. The opening length of the strip hole 612 is greater than the diameter of the adjusting bolt 63. The connecting bolt 62 is threadedly penetrated in the locking hole 611, and the connecting bolt 62 passes through the locking hole 611 and is threadedly penetrated to the trough body. The adjusting bolt 63 is slidably penetrated in the strip hole 612, and the adjusting bolt 63 is threadedly penetrated to another trough box 1. In this embodiment, screw holes for the connecting bolt 62 and the adjusting bolt 63 to pass through are pre-opened on the trough box 1.

[0040] When connecting adjacent trough boxes 1 horizontally at the end of the trough box 1 away from the end head 2, the construction personnel will slot the connecting groove 61 into the connection of the adjacent trough boxes 1, so that the connecting groove 61 is simultaneously inserted into the inner walls of the two trough boxes 1 to be connected, and then the connecting bolt 62 is threaded into the locking hole 611 and threaded into the screw hole pre-opened on the trough box 1, so as to complete the connection between the connecting groove 61 and one section of the trough box 1, and then the construction personnel will pass the adjusting bolt 63 through the bar hole 612 and threaded into the screw hole pre-opened on the other trough box 1, so as to complete the connection between the connecting groove 61 and the other section of the trough box 1. At this time, the connecting groove 61 closes the deformation gap between the two trough boxes 1, improves the gap at the deformation gap between the two trough boxes 1 and reduces the protection of the cable, and at this time the adjusting bolt 63 can slide in the bar hole 612, and then the trough box 1 connected with the adjusting bolt 63 can move relative to the connecting box and the other section of the trough box 1, and the two trough boxes 1 can be relatively displaced in the horizontal direction to avoid the adjacent trough boxes 1 being squeezed against each other and damaged under the action of thermal expansion and contraction.

[0041] Reference Figure 2 , Figure 4 The side wall of the open end of the trough box 1 is bent toward the inside of the trough box 1. The side wall of the open end of the trough box 1 bent toward the inside of the trough box 1 reduces the sharpness of the end of the trough box 1 and reduces the possibility of construction workers being scratched by the side wall of the open end of the trough box 1 during construction.

[0042] Reference Figure 1 , Figure 5The shielding mechanism 7 is installed on the trough box 1, and the shielding mechanism 7 is used to close the upper end opening of the trough box 1. The shielding mechanism 7 includes a sliding cover 71 and an arc-shaped cover plate 72. The sliding cover 71 is hollow inside and open at the lower end. The inner diameter of the sliding cover 71 is the same as the outer diameter of the trough body. The sliding cover 71 is slidably buckled on the top wall of the trough body to close the upper opening of the trough body; the arc-shaped cover plate 72 is installed on the trough box 1, and the arc-shaped cover plate 72 is used to close the upper opening of the curved section of the adjacent trough box 1. The cover plate 72 includes a first baffle plate 721, a second baffle plate 722, a second corrugated plate 723 and a locking assembly 724. The first baffle plate 721 and the second baffle plate 722 are both trough bodies with a hollow interior and an opening at the lower end. The inner diameters of the first baffle plate 721 and the second baffle plate 722 are the same as the outer diameter of the trough box 1. The two ends of the second corrugated plate 723 are respectively connected to the first baffle plate 721 and the second baffle plate 722. In this embodiment, the second corrugated plate 723 is combined with a stainless steel corrugated plate; Figure 6 , multiple groups of locking assemblies 724 are respectively installed on the first baffle plate 721 and the second baffle plate 722, and the locking assemblies 724 are used to position the first baffle plate 721 or the second baffle plate 722 on the trough box 1. The locking assemblies 724 include a control rod 7241 and a block 7242. The control rod 7241 is rotatably installed on the first baffle plate 721 or the second baffle plate 722, and the block 7242 is installed on the control rod 7241. The distance between the block 7242 and the inner wall of the first baffle plate 721 or the second baffle plate 722 is the same as the thickness of the side wall bent at the open end of the trough box 1.

[0043] After the construction personnel conveniently and quickly lay the cable into the trough box 1 from the upper opening of the trough box 1, they snap the sliding cover 71 onto the open end of the trough box 1, and the upper opening of the trough box 1 can be closed by the sliding cover 71. The construction personnel rotate the first baffle plate 721 and the second baffle plate 722 to adjust the angle between the first baffle plate 721 and the second baffle plate 722 to be consistent with the angle between adjacent trough boxes 1. During the adjustment process, the second corrugated plate 723 expands and bends accordingly. Then the construction personnel fit the first baffle plate 721 to the open end of one of the trough boxes 1, fit the second baffle plate 722 to the open end of the other trough box 1, and then By rotating the control rod 7241, the control rod 7241 drives the block 7242 to rotate, so that the block 7242 rotates to abut against the lower part of the bend at the open end of the trough box 1, and the first baffle plate 721 and the second baffle plate 722 can be positioned at the open ends of the two trough boxes 1 respectively.
