Description

Technical Field

[0001] This utility model relates to the field of PLC control cabinet technology, and in particular to a high-efficiency and energy-saving PLC control cabinet. Background Technology

[0002] PLC control cabinet refers to programmable control cabinet. A control cabinet is a complete set of control cabinets that can control motors and switches. PLC control cabinets have protection functions such as overload, short circuit, and phase loss protection, and are widely used in industries such as power, metallurgy, chemical, papermaking, and environmental wastewater treatment.

[0003] An existing energy-efficient PLC control cabinet for a bobbin yarn machine (Announcement No.: CN215735522U) is designed with a lower cavity, centrifugal fan, mounting bracket, control panel, upper cavity, cable management plate, stuffing box, cable management hole, front clamp, arc-shaped clamping groove, rear clamp, tension spring, positioning protrusion, positioning slot, limit rotating plate, one-way exhaust valve, and temperature sensor. This design features intelligent heat dissipation and efficient cable management, addressing the shortcomings of existing PLC control cabinets that lack intelligent heat dissipation but rely on front clamps, tension springs, and limit rotating plates for cable clamping, resulting in less than ideal fixation. Furthermore, when the equipment vibrates or experiences external impact, the spring force alone is insufficient to counteract these disturbances, easily leading to loosening and detachment of the cable management contacts. Poor contact increases contact resistance, causing the control cabinet to consume additional power. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a highly efficient and energy-saving PLC control cabinet.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A high-efficiency and energy-saving PLC control cabinet includes a control cabinet body and a partition. The partition is fixedly connected to the inner wall of the control cabinet body. A cable management plate is fixedly provided at the outer end of the partition. The cable management plate has cable through holes. A rectangular frame is fixedly provided on one side of the cable management plate. A fixing block is fixedly provided at one end of the rectangular frame. A crossbar is fixedly installed on the fixing block. A clamp is fixedly provided on the crossbar. The clamps are evenly distributed on the crossbar. A slider is provided at the end of the rectangular frame away from the fixing block. The slider is slidably connected to the rectangular frame. A scale plate is fixedly provided on the outer wall of the rectangular frame. A second crossbar is fixedly provided on the slider. A pressure block is fixedly installed on the second crossbar.

[0007] As a further embodiment of this utility model, a protrusion is fixedly installed at the upper end of the threading hole, a limiting rod is movably provided on the protrusion, and a spring is sleeved on the limiting rod.

[0008] As a further embodiment of this utility model, the slider is slidably connected to the scale plate, the rectangular frames are symmetrically distributed on the cable management plate, one end of the limiting rod is fixedly provided with an arc-shaped block, and a sealing door is installed on the main body of the control cabinet via a hinge.

[0009] As a further embodiment of this utility model, a screw is movably provided inside the rectangular frame, and a button is fixedly provided at the outer end of the screw. The end of the screw near the button is connected through the rectangular frame.

[0010] As a further embodiment of this utility model, the slider is threadedly connected to the screw, and the end of the screw away from the button is connected to the inner wall of the rectangular frame via a pivot.

[0011] As a further embodiment of this utility model, the inner wall of the arc-shaped block is fixedly provided with an anti-wear plate, the arc-shaped blocks are evenly distributed on the thread hole, and the two ends of the spring are respectively fixedly connected to the arc-shaped block and the protrusion.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] When used in a PLC control cabinet, multiple sets of limit rods and springs are installed on the cable management board. By pulling the electronic component wire harnesses through the wire holes and classifying them into the clamps, multiple sets of arc-shaped blocks initially limit the wire harnesses within the wire holes. Anti-wear plates are used to prevent wear on the wire harnesses at the wire holes. By turning the button, the second horizontal bar moves closer to the first horizontal bar, pushing multiple sets of pressure blocks to engage with the corresponding clamps, thus pressing and fixing each set of wire harnesses onto the cable management board. This enhances the positioning effect of the wire harnesses and avoids extra power consumption in the control cabinet due to loose wire harnesses or poor contact. At the same time, classifying different wire harnesses facilitates quick inspection and maintenance by the staff. Attached Figure Description
