[0002] A cable tray is a support system used to support and manage cable wiring, widely applied in various buildings and facilities, providing a safe and orderly path for cables. It is made of materials such as metal or fiberglass, having good mechanical strength and corrosion resistance, and can effectively protect cables from the external environment. Cable trays are divided into various types such as ladder-type, tray-type, trough-type, and combined type, suitable for different installation requirements and scenarios. By using a cable tray, not only can the cables be neatly arranged, facilitating maintenance and expansion, but also the safety of the system can be improved, reducing the risk of electrical faults.

[0003] Currently, during the installation of existing cable trays, it is usually manually operated to pass the cable through the cable tray for installation. During the entire process of passing the cable, the cable tray usually needs to be separated, then the cable is installed first, and subsequently the cover plate of the cable tray is closed to complete the cable installation work. During the entire installation process, the installation of the cable tray needs to be carried out in two steps, making the cable installation process more cumbersome and the installation efficiency lower. Summary of the Invention

[0004] In view of this, the present invention provides a cable tray with a traction function.

[0005] The technical solution is as follows: A cable tray with a traction function includes a bottom cover, an installation frame, connecting strips, locking studs, a guiding mechanism, and a traction mechanism. The installation frame is snap-connected to the top of the bottom cover. Locking studs are connected to both sides of the connecting strip. Two slots are provided on each side of the installation frame, and the locking studs can be stuck at the slots.

The extrusion shaft passes through the opening position of the guide sleeve. A knob is connected to the extrusion shaft.

[0009] Furthermore, it also includes a protection mechanism, which includes a shielding sleeve, a bidirectional rack and an outer gear ring. The shielding sleeve is rotatably connected to the middle of the guide sleeve, and the shielding sleeve can block the inspection port. A notch is opened in the middle of the top of the shielding sleeve, and the shielding sleeve can be rotated one hundred and eighty degrees to align the notch with the inspection port. The shielding sleeve is connected to the outer gear ring, and three bidirectional racks are evenly spaced and connected to the top of the bottom cover. The two sides of the bidirectional rack are respectively engaged with the two outer gear rings adjacent to it.

[0010] Furthermore, a fixing mechanism is included, and the fixing mechanism includes a rotating shaft and a fixed clamping plate. The rotating shaft is rotatably connected to the guide sleeve, and the rotating shaft is connected to the fixed clamping plate.

DETAILED DESCRIPTION

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] A cable tray with a traction function, as Figures 1-4 shown, includes a bottom cover 1, an installation frame 2, connecting bars 31, locking columns 32, a guiding mechanism and a traction mechanism. The installation frame 2 is clamped on the top of the bottom cover 1. Locking columns 32 are connected to both the front and rear sides of the connecting bar 31. Two card slots are provided on each of the left and right sides of the installation frame 2. The locking columns 32 can be stuck in the card slots, and different installation frames 2 can be clamped on the locking columns 32 through the card slots to realize the connection work between the cable trays. A guiding mechanism for guiding the cables and a traction mechanism for pulling the cables are provided on the installation frame 2.

[0031] As Figure 2 and Figure 3 shown, the guiding mechanism includes a connecting plate 41 and a guiding sleeve 42. Connecting plates 41 are connected to both the left and right sides inside the installation frame 2. Six guiding sleeves 42 are evenly spaced and connected between the two connecting plates 41. The cables can pass through the guiding sleeves 42, and the guiding sleeves 42 can guide and support the cables when the cables are connected to each other.

[0032] As Figure 4 shown, a maintenance opening 43 is provided in the middle of the bottom of the guiding sleeve 42. When it is necessary to maintain the cables, the bottom cover 1 can be opened, and then the cables can be maintained through the maintenance opening 43 at the bottom of the guiding sleeve 42.

[0033] As Figure 2 and Figure 4 shown, the traction mechanism includes a sliding sleeve 44, an elastic member 45, a pressing shaft 46 and a knob 47. Two sliding sleeves 44 are slidably connected to both the front and rear sides on the right side of the installation frame 2. The two sliding sleeves 44 are symmetrically arranged up and down. An elastic member 45 is connected between the two sliding sleeves 44. The elastic member 45 is a buffer spring. A pressing shaft 46 is rotatably connected inside the sliding sleeve 44. Openings are provided on both the upper and lower sides on the right side of the guiding sleeve 42. The pressing shaft 46 passes through the opening positions of the guiding sleeve 42. After the cables pass through the guiding sleeve 42, the rotation of the pressing shaft 46 can drive the cables to rotate, thereby transmitting the cables. A knob 47 is connected to the front side of the pressing shaft 46. By operating the knob 47, the pressing shaft 46 can be rotated more conveniently.

[0034] When it is necessary to pull the cable bridge, this bridge can be used. When in use, the bridge is installed, and then the cable is passed through the guide sleeve 42. When operating the cable to pass through the guide sleeve 42, it is only necessary to extend the cable into the guide sleeve 42 so that the cable is located between the two extrusion shafts 46. The cable can squeeze the two extrusion shafts 46 away from each other. The two extrusion shafts 46 move away from each other, which will drive the two sliding sleeves 44 away from each other. The elastic member 45 is stretched. At this time, the elastic member 45 applies tension to the two sliding sleeves 44, so that the two sliding sleeves 44 and the two extrusion shafts 46 move closer to each other to press the cable. At this time, the knob can be turned. 47 drives the extrusion shaft 46 to rotate, and the extrusion shaft 46 can transport the cable to the left when rotating, thereby playing the role of pulling and transporting the cable. In this way, the cable tray can be used to set up the cable, and during the operation, only the knob 47 needs to be turned to transmit the cable, thereby playing the role of pulling the cable. There is no need for staff to operate the cable to pass through the guide sleeve 42, which is more convenient to operate. When there is a problem with the cable and it needs to be repaired, the bottom cover 1 can be removed, and then the cable can be pulled out from the inspection port 43 to inspect the cable, so as to facilitate the maintenance of the cable.

[0035] like Figure 5 and Figure 6 As shown, a protective mechanism is also included, which includes a shielding sleeve 51, a two-way rack 52 and an outer gear ring 53. The shielding sleeve 51 is rotatably connected to the outer side of the middle part of the guide sleeve 42. The shielding sleeve 51 can block the inspection port 43 to prevent the inspection port 43 from leaking out. A notch is provided in the middle of the top of the shielding sleeve 51. The shielding sleeve 51 can be rotated one hundred and eighty degrees to align the notch with the inspection port 43 to facilitate maintenance work. The outer gear ring 53 is connected to the right side of the shielding sleeve 51, and three two-way racks 52 are evenly spaced and connected to the top of the bottom cover 1. The two sides of the two-way rack 52 are respectively engaged with the two outer gear rings 53 adjacent to it, so that the bottom cover 1 drives the two-way rack 52 to move downward when it is removed, and the two-way rack 52 can drive the outer gear ring 53 to rotate.

[0036] Under normal conditions, the shielding sleeve 51 can block the inspection port 43, preventing the cable from passing through the guide sleeve 42 through the inspection port 43 when drilling into the guide sleeve 42, ensuring that the cable installation process can proceed smoothly. When the cable needs to be inspected, the bottom cover 1 is removed. When removing the bottom cover 1, the bottom cover 1 is pulled downward. The downward movement of the bottom cover 1 can drive the two-way rack 52 to move downward. The downward movement of the two-way rack 52 can rub the two outer gear rings 53 to rotate. The outer gear rings 53 can drive the shielding sleeve 51 to rotate when rotating. The shielding sleeve 51 no longer blocks the inspection port 43 after rotation, and the inspection operation can be carried out at this time. In this way, the inspection port 43 can be blocked during the installation of the cable, and the inspection port 43 can be automatically opened when maintenance is required, which is more convenient to operate.

[0037] like Figure 7 As shown, a fixing mechanism is also included, which includes a rotating shaft 61 and a fixed clamping plate 63. The right side of the guide sleeve 42 is rotatably connected to the rotating shaft 61, and the rotating shaft 61 is connected to the fixed clamping plate 63. The fixed clamping plate 63 can be flipped to resist the cable and clamp the cable, thereby fixing the cable.

[0038] like Figure 7 As shown, a toggle wheel 62 is also included. The bottom of the rotating shaft 61 is connected to the toggle wheel 62. The rotating shaft 61 is driven to rotate by the toggle wheel 62, which is more convenient during operation.

[0039] During the installation process, if it is necessary to connect the lines between cables, in order to prevent the cables from loosening, the toggle wheel 62 can be rotated to drive the rotating shaft 61 to rotate. When the rotating shaft 61 rotates, it can drive the fixed card 63 to rotate. When the fixed card 63 rotates, it can resist the cable, thereby fixing the cable, preventing the cable from loosening when the cable line is connected, affecting the work of the cable line connection.

[0040] like Figure 8 As shown, a driving mechanism is also included, which includes a reduction motor 71 and a locking chuck 72. The reduction motor 71 is installed on the right side of the front side of the mounting frame 2, and the locking chuck 72 is connected to the output shaft of the reduction motor 71. The locking chuck 72 is engaged with the knob 47 so that the locking chuck 72 can drive the knob 47 to rotate, thereby driving the extrusion shaft 46 to rotate.

[0041] When it is necessary to control the rotation of the extrusion shaft 46, the reduction motor 71 can be used to drive the locking chuck 72 to rotate. When the locking chuck 72 rotates, it will drive the extrusion shaft 46 to rotate. When the extrusion shaft 46 rotates, it can transmit the cable. In this way, the effect of automatically driving the extrusion shaft 46 to rotate can be achieved, and there is no need to manually drive the extrusion shaft 46 to rotate, which is more convenient to operate.

[0042] like Figure 9 and Figure 10 As shown, a locking mechanism is also included, which includes a guide frame 81, a sliding frame 82 and a locking block 83. The left and right sides of the lower inner portion of the mounting frame 2 are connected to the guide frame 81, and the sliding frame 82 is slidably connected to the guide frame 81. The sliding frame 82 can slide back and forth along the guide frame 81, and the left and right sides of the lower portion of the sliding frame 82 are connected to the locking block 83. The bottom cover 1 is provided with a card slot on the left and right sides, and the locking card block 83 can be inserted into the card slot, thereby fixing the mounting frame 2 and the bottom cover 1 together.

[0043] After the bottom cover 1 and the mounting frame 2 are assembled together, the sliding carriage 82 can be pulled backward. When the sliding carriage 82 slides, it drives the locking block 83 to move together. When the locking block 83 moves, it can be inserted into the card slot, thereby connecting the bottom cover 1 and the mounting frame 2 together, preventing the bottom cover 1 from detaching from the mounting frame 2, so as to achieve the clamping work between the bottom cover 1 and the mounting frame 2. When it is necessary to remove the bottom cover 1, only the sliding carriage 82 needs to be pulled forward, so that the sliding carriage 82 drives the locking block 83 to disengage from the card slot, and then the bottom cover 1 can be removed. In this way, the bottom cover 1 can be fixed more conveniently after it is installed.

[0044] As Figure 11 shown, it further includes a connecting sling 9. Two connecting slings 9 are connected between the bottom cover 1 and the mounting frame 2. Through the connecting sling 9, the bottom cover 1 and the mounting frame 2 can be connected together, preventing the bottom cover 1 from being lost.

[0045] The above embodiments are only preferred embodiments of the present invention and are not used to limit the scope of implementation of the present invention. Therefore, all equivalent changes made according to the content described in the claims of the present invention should be included within the scope of the claims of the present invention.
