Description

Technical Field

[0001] This utility model relates to the field of cable fixing bracket technology, specifically a cable fixing bracket for switch cabinets. Background Technology

[0002] Switchgear is a very important electrical device in the power system. Its main function is to open, close, control and protect electrical equipment during the power generation, transmission, distribution and energy conversion process. During use, switchgear requires cable fixing brackets to fix the cables.

[0003] For example, announcement number CN222146857U (titled "A Cable Tray for a High-Voltage Switchgear with Fixing Straps") includes a first frame, a second frame on one side of the first frame, a connecting frame slidably connected inside both the first and second frames, and a fixing column fixedly connected inside both the first and second frames. A spring is sleeved on the outer wall of each fixing column, a push-pull block is fixedly connected to one end of the spring, a sliding column is fixedly connected inside the push-pull block, the fixing column is slidably connected inside the sliding column, the sliding column is slidably connected inside the connecting frame, and a fixing component is provided inside the connecting frame. Pushing and pulling the push-pull block allows for pushing and pulling... The block drives the sliding column to detach from the inside of the connecting frame, thereby allowing the connecting frame and the fixing components to detach from the first or second frame. This achieves the effect of quickly disassembling the fixing components, solving the problem of the overly complicated disassembly process and reducing the workload of the staff to a certain extent. By tightening the screws, the screws are no longer screwed into the first frame, and the screws can remain in the connecting plate without being removed. At this time, the first and second frames can be quickly disassembled and separated, thus facilitating the disassembly of the equipment by the staff and solving the problem of the screws being easily lost when the staff disassembles the first and second frames.

[0004] The aforementioned cable trays, with their detachable structure, facilitate assembly and use inside the switchgear. However, when the length of the fixed cables is long, cable management becomes inconvenient, leading to a messy cable situation inside the switchgear. Therefore, we provide a cable fixing bracket for switchgear. Utility Model Content

[0005] The purpose of this utility model is to provide a cable fixing bracket for switch cabinets, so as to solve the problem mentioned in the background art that the existing cable trays are easy to assemble and use inside the switch cabinet through the detachable structure, but when the length of the fixed cable is long, the cable management is inconvenient, which leads to the problem of messy cables inside the switch cabinet.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a cable fixing bracket for a switch cabinet, comprising a switch cabinet, a cable inlet groove provided at the bottom of the switch cabinet, an inner filling plate installed inside the cable inlet groove, and two vertical uprights provided inside the switch cabinet, with an extension plate welded to the bottom of each of the two vertical uprights. Also includes: The sliding track is welded to the front end face of the vertical pole. Three sliding tracks are provided on each of the two vertical poles, and an inner connecting plate is inserted into the interior of each of the three sliding tracks. A bearing seat plate is welded to one side of the outer wall of the inner connecting plate. The equipment mounting plate is positioned above the bearing base plate, and a winding rod is provided on one side of the equipment mounting plate. Two connecting end blocks are welded to both ends of the winding rod, and the two connecting end blocks are integrally formed with the bearing base plate. The suspension rod is welded to the upper end of the extension plate, and a connecting plate is welded to one end of the suspension rod. The connecting plate is fixedly connected to the inner filling plate by bolts. The inner filling plate has wire holes arranged inside. The wire hole seat is welded to the lower end of the bearing plate. There are five wire hole seats on the bearing plate, and a limit block is attached to the winding rod with adhesive.

[0007] Preferably, a limit strip is provided at the front end of the slide rail, a connecting shaft is provided at one end of the limit strip and the rotatable connection position of the slide rail, and a locking bolt is installed at the other end of the limit strip, and the limit strip is fixedly connected to the slide rail by the locking bolt.

[0008] Preferably, two rollers are rotatably arranged in the bottom groove of the inner insert plate via a rotating shaft, and the inner insert plate is rolledly connected to the bearing seat plate through the two rollers.

[0009] Preferably, four connecting rods are provided between the bearing base plate and the equipment mounting hole plate, and the two ends of the connecting rods are welded to the bearing base plate and the equipment mounting hole plate respectively.

[0010] Preferably, a handle is provided on the front end face of the inner connector plate, and the handle and the inner connector plate are an integral structure.

[0011] Preferably, the inside of the wire passage hole is provided with four rubber sheets, which are semi-circular in structure, and the four rubber sheets are fixedly connected to the inner wall of the wire passage hole by nail-free adhesive.

[0012] Preferably, the bearing seat plate has a ventilation groove inside, and the ventilation groove and the bearing seat plate are an integral structure.

[0013] Compared with the prior art, the beneficial effects of this utility model are: The incoming and outgoing lines of this utility model switchgear are assisted by the cable passing holes inside the inner plate. The cable first passes through the cable passing hole seat inside the switchgear. Then, when the cable is too long, the cable is first wrapped around the winding rod several times to shorten the cable length. Then, upper limit blocks are installed on both sides of the winding loop to lock and fix it, preventing the wrapped cable from coming loose. This achieves the purpose of cable management. The entire cable fixing frame structure can be removed from the inside of the switchgear, which is convenient for internal inspection and maintenance of the switchgear. This overcomes the problem that existing cable trays, which are easy to assemble and use inside the switchgear with a detachable structure, are inconvenient to manage when the fixed cable is long, and the cable inside the switchgear is prone to mess.
