[0028] The terms used in the present invention are those general terms currently widely used in the art in consideration of the functions of the present invention, but these terms may vary according to the intention of a person of ordinary skill in the art, precedents, or new technologies in the art. In addition, specific terms may be selected by the applicant, and in this case, their detailed meanings will be described in the detailed description of the present invention. Therefore, the terms used in the specification should not be understood as simple names, but rather as a general description based on the meaning of the terms and the present invention.

[0029] Reference Figure 1~Figure 5 The present embodiment provides a cable tray that is convenient for wiring, including a support mechanism 1, which includes a support side 11 and a connecting shaft 12 arranged on the support side 11, and a contact plate 13 is provided on the support side 11; it should be noted that the support side 11 is symmetrically arranged on both sides of the contact plate 13, and a contact plate 13 is provided at both ends of the support side 11, wherein each support side 11 is provided with two symmetrically arranged connecting shafts 12.

[0030] The protection mechanism 2 includes a side plate 21, a bottom plate 22 is provided on the side plate 21, an entry channel 23 and a transverse groove 24 are provided on the side plate 21, the entry channel 23 and the transverse groove 24 are connected, and also includes a sliding groove 26 provided on the side plate 21; the side plates 21 are provided on both sides of the bottom plate 22, and the entry channels 23 and the transverse groove 24 are provided at both ends of the side plates 21, and are symmetrically arranged at the two ends of the side plates 21.

[0031] The clamping mechanism 3 includes a sliding shaft 31 slidably arranged in the sliding groove 26, and a clamping arm 32 arranged on the sliding shaft 31, and also includes a No. 1 tension spring 33 arranged on the clamping arm 32, one end of the No. 1 tension spring 33 is connected to the side plate 21; the sliding shaft 31 can not only slide in the sliding groove 26, but also rotate in the sliding groove 26.

[0032] The connecting shaft 12 is slidably disposed in the transverse groove 24 .

[0033] An arc-shaped limit block 211 is disposed on the side plate 21 . The arc-shaped limit block 211 can limit the deflection angle of the clamping arm 32 .

[0034] A crossbeam 14 is disposed on the supporting side 11 . A plurality of crossbeams 14 are disposed and are evenly distributed between the symmetrically disposed supporting side 11 , and can be used to support the cables.

[0035] When in use, the support mechanism 1 is the main frame of the cable tray. The support mechanism 1 is first erected and installed, and then the cable is laid. Due to the setting of the resistance plate 13 and the crossbeam 14, the cable can be effectively supported. During the wiring process of the cable, since the bottom of the support mechanism 1 is not in a closed state, the operator can adjust the position of the cable conveniently, which is convenient for wiring operations and increases the operating space, thereby improving the convenience of wiring, reducing the difficulty of wiring, and improving the efficiency of wiring.

[0036] After the preliminary wiring is completed, the protective mechanism 2 is installed, and the cable is protected and sealed through the bottom plate 22 to complete the assembly of the cable tray. The installation process of the protective mechanism 2 is as follows: first align the entry channel 23 at one end of the protective mechanism 2 with the connecting shaft 12 at one end of the supporting mechanism 1, and make the connecting shaft 12 slide into the interior of the transverse groove 24 through the entry channel 23. After the connecting shaft 12 slides into the transverse groove 24 away from the end of the entry channel 23, the entry channel 23 at the other end of the protective mechanism 2 can be aligned with the connecting shaft 12 at the other end of the supporting mechanism 1, and then the protective mechanism 2 is controlled to slide as a whole so that the connecting shafts 12 at both ends can be in the transverse groove 24. At this time, the connection between the protective mechanism 2 and the supporting mechanism 1 can be achieved.

[0037] Among them, the clamping mechanism 3 can play a locking role between the supporting mechanism 1 and the protective mechanism 2. The movement process of the clamping mechanism 3 when assembled between the supporting mechanism 1 and the protective mechanism 2 is as follows: when the connecting shaft 12 enters the entry channel 23, it will conflict with the clamping arm 32. After the clamping arm 32 is conflicted, the following two movement modes can be generated. One is that the clamping arm 32 deflects, so that the first tension spring 33 stretches, or the sliding shaft 31 slides along the sliding groove 26, and the clamping arm 32 slides. Movement, both movement modes will cause the clamping arm 32 to stop blocking the entrance channel 23, so that the connecting shaft 12 can slide smoothly into the transverse groove 24 until it slides a certain distance and loses the resistance with the clamping arm 32. Under the pulling force of the No. 1 tension spring 33, the clamping arm 32 will be reset and resist on the arc-shaped limit block 211. At this time, the connecting shaft 12 located in the transverse groove 24 will not be able to slide out of the transverse groove 24, and will be hindered by the clamping arm 32 during the sliding out process.

[0038] An eccentric shaft 321 is provided on the clamping arm 32 , a fixed shaft 212 is provided on the side plate 21 , two ends of the first tension spring 33 are respectively connected to the eccentric shaft 321 and the fixed shaft 212 , and the eccentric shaft 321 is arranged to deviate from the rotation axis of the clamping arm 32 .

[0039] A protruding portion 322 is provided on the clamping arm 32 , and a resisting portion 323 is provided on the clamping arm 32 . When the connecting shaft 12 enters the passage 23 , it can resist the resisting portion 323 .

[0040] It should be noted that, refer to Figure 2 When the connecting shafts 12 at both ends are located in the transverse grooves 24, the protrusions 322 on the clamping arms 32 are just in a state of conflict with the connecting shafts 12. Therefore, the locking between the protective mechanism 2 and the supporting mechanism 1 can be completed. After the supporting mechanism 1 and the protective mechanism 2 are connected, the protective mechanism 2 will not fall off and separate easily.

[0041] During subsequent use, when it is necessary to conduct secondary wiring in the cable tray, the clamping arm 32 at one end can be manually pushed to slide along the sliding groove 26, so that the clamping arm 32 loses the obstruction to the entry channel 23, and one end of the protective mechanism 2 is separated first, and then the other end of the protective mechanism 2 is separated, so as to realize the disassembly of the protective mechanism 2, which is convenient for secondary wiring and use.

[0042] It should be noted that, refer to Figure 3 and Figure 4 The end of the sliding shaft 31 is protruding from the surface of the side plate 21 close to the bottom plate 22. Therefore, after separating one end of the protective mechanism 2, when separating the other end of the protective mechanism 2, the side plate 21 can be deflected by the gravity of the protective mechanism 2 itself. Figure 6 After the right end of the protective mechanism 2 is separated from the supporting mechanism 1, the side plate 21 will deflect under the action of gravity, and the deflection of the side plate 21 will cause the end of the sliding shaft 31 to conflict with the bottom surface of the contact plate 13. Therefore, the sliding shaft 31 will slide along the sliding groove 26. Finally, before the side plate 21 is close to the vertical state, the sliding of the sliding shaft 31 makes the clamping arm 32 lose the obstruction to the entry channel 23, and the connecting shaft 12 can slide out of the entry channel 23, thereby realizing the automatic separation of the protective mechanism 2. The original two ends need to be disassembled by hand, but now only one end needs to be disassembled first. When the operator releases the protective mechanism 2, the other end can automatically complete the disassembly and separation, further improving the convenience of installation and disassembly.

[0043] An arc groove 25 is formed on the side plate 21 , and the arc groove 25 is connected to the transverse groove 24 .

[0044] During secondary wiring or maintenance, it is only necessary to make the bottom plate 22 of the protective mechanism 2 no longer cover the bottom of the supporting mechanism 1, and there is no need to completely separate the protective mechanism 2 from the supporting mechanism 1. Therefore, the connection between one end of the protective mechanism 2 and the supporting mechanism 1 can be separated first, and then the protective mechanism 2 can be pushed, and the gravity of the protective mechanism 2 can be cooperated to make the connecting shaft 12 slide into the arc groove 25. At this time, when the operator releases the protective mechanism 2, even if the sliding shaft 31 is resisted by the resistance plate 13 and causes the entry channel 23 to open, the protective mechanism 2 will not be separated from the supporting mechanism 1, but the side plate 21 will be suspended by the connecting shaft 12, so that the protective mechanism 2 can be installed after the secondary wiring maintenance, saving the installation steps and improving the installation efficiency.

[0045] A fixing screw 34 is provided through the sliding shaft 31 , and a rolling column 35 is threadedly connected to one end of the fixing screw 34 .

[0046] Due to the provision of the rolling column 35 , the area where the sliding shaft 31 abuts against the abutting plate 13 can be increased.

[0047] A deflection slot 111 is formed on the supporting side edge 11 .

[0048] Reference Figure 7 The rolling column 35 also has the following functions. By first disassembling the fixing screw 34 and removing the rolling column 35, the arc groove 25 at one end of the protective mechanism 2 is then connected to the connecting shaft 12. At this time, the sliding shaft 31 can be resisted by the resistance plate 13 and then slide along the sliding groove 26 through the rotation of the side plate 21 until the sliding shaft 31 slides to align with the deflection groove 111. At this time, the clamping arm 32 can be reset by the tension of the tension spring, and the sliding shaft 31 slides into the deflection groove 111. In this state, the rolling column 35 is installed again. When laying the cable, the cable is passed between the rolling column 35 and the crossbeam 14. The rolling column 35 can limit the cable when laying the cable, which is convenient for wiring operations and prevents the cable from detaching from the bridge.

[0049] It also includes a moving groove 4 provided on the side plate 21, and the moving groove 4 includes an upper straight groove 41, a connecting groove 42, and a lower straight groove 43 provided on the side plate 21 and connected in sequence; the connecting groove 42 is arranged in an inclined manner, and the height of the upper straight groove 41 is higher than the lower straight groove 43; it also includes a blocking mechanism 5 provided on the side plate 21, and the blocking mechanism 5 includes a baffle 51 slidably provided in the moving groove 4, and a protrusion 52 provided on the baffle 51, and a second tension spring 53 is provided on the protrusion 52; a positioning shaft 213 is provided on the side plate 21, and one end of the second tension spring 53 is connected to the positioning shaft 213. The moving groove 4 also includes a narrow groove 44 provided on the side plate 21, and the narrow groove 44 is connected to the lower straight groove 43; the narrow groove 44 is connected to the arc groove 25, and a thick shaft 511 and a thin shaft 512 are provided on the baffle 51.

[0050] Reference Figure 5 and Figure 8 When the baffle 51 is not under force, the tension of the No. 2 tension spring 53 will cause the thick shaft 511 to be located below the positioning shaft 213. Since the thick shaft 511 is away from the positioning shaft 213 when sliding toward the upper straight groove 41 and when sliding toward the narrow groove 44, the No. 2 tension spring 53 can enable the baffle 51 to be located at the lower straight groove 43 when it is not under force.

[0051] When the connecting shaft 12 is located in the arc groove 25, due to the gravity of the protective mechanism 2, it will be difficult for the connecting shaft 12 to move to the side of the transverse groove 24 close to the entrance channel 23. At this time, it is only necessary to slide the connecting shaft 12 toward the end of the transverse groove 24 away from the entrance channel 23. The connecting shaft 12 will contact the protrusion 52 and push the baffle 51 to move. When the thick shaft 511 slides into the connecting groove 42, the baffle 51 will tilt. As the movement distance increases, the thick shaft 511 moves into the upper straight groove 41, and the thin shaft 512 also moves close to the upper straight groove 41. The protrusion 52 will lose contact with the connecting shaft 12. Under the tension of the No. 2 tension spring 53, the baffle 51 is reset. At this time, Move the connecting shaft 12 toward the direction of the entrance channel 23, and the protrusion 52 will abut against the connecting shaft 12, which will push the baffle 51 to slide together until the thin shaft 512 moves into the narrow groove 44. At this time, the connecting shaft 12 has passed the position of the arc groove 25. As the movement distance increases, the thin shaft 512 will disengage from the narrow groove 44 and enter the arc groove 25. Since the thick shaft 511 is too thick to slide into the narrow groove 44, the sliding of the connecting shaft 12 will abut against the protrusion 52, causing the baffle 51 to deflect, disengage from the abutment with the protrusion 52, and cause the connecting shaft 12 to move to the side of the transverse groove 24 close to the entrance channel 23, which can further facilitate the installation of the protective mechanism 2 after the secondary wiring is completed.

[0052] Finally, it should be pointed out that the methods and devices described in detail above are only embodiments, and those skilled in the art can modify these embodiments in different ways without departing from the scope of the present invention.
