Description

Technical Field

[0001] This utility model belongs to the field of PLC cabinet manufacturing technology, and in particular relates to a PLC cabinet test bench with recording function. Background Technology

[0002] A PLC cabinet is an industrial electrical control cabinet specifically designed for installing and protecting PLCs and their associated equipment. It is widely used in automated production lines, mechanical equipment control, process control, and other fields. In the production and manufacturing process of PLC cabinets, testing is a crucial step to ensure their functionality, safety, and reliability. The testing of PLC cabinets mainly includes electrical testing, functional testing, communication testing, and environmental testing. During the testing of PLC cabinets, a large number of devices and loads are used. Commonly used testing devices include computers, multimeters, oscilloscopes, and power signal generators. Commonly used loads include motors and heating rods. In addition, different power connections need to be prepared. Since equipment such as voltage regulators, power testers, and motors are relatively bulky, they are not convenient to move in the testing workshop. Moreover, test data can only be recorded manually, which has poor accuracy and is easy to lose. In addition, various power connection cables are not convenient to store.

[0003] To address these issues, we provide a PLC cabinet test bench with recording capabilities. Utility Model Content

[0006] A further feature of this invention is that multiple cable conduits are inserted at equal intervals below the rear end face of the cabinet, with the front ends of the cable conduits extending to the inside of the cabinet.

[0007] A further feature of this invention is that a cabinet door is rotatably connected to the front end face of the cabinet, and a folding table for placing a laptop is fixedly connected to the cabinet door.

[0008] A further feature of this invention is that multiple circuit breakers are fixedly connected at equal intervals above the front end face of the control board, and a PLC controller is fixedly connected below the front end face of the control board.

[0009] A further feature of this invention is that multiple sockets are fixedly connected at equal intervals inside the equipment cavity located at the center of the cabinet, and the sockets are electrically connected to the power supply via wires.

[0010] A further feature of this invention is that a first threaded rod is rotatably connected to one side above the rear end face of the cabinet, and a first knob is fixedly connected to both ends of the first threaded rod.

[0033] The rest of the structure is the same as in Example 1.

[0034] The operation process of this embodiment is as follows: When it is necessary to adjust the height of all hooks 305, rotate the first knob 301b. The first knob 301b drives the moving plate 301 to move through the first threaded rod 301a and the first slider 301c, so that the moving plate 301 drives all hooks 305 to rise and fall synchronously. When it is necessary to adjust the height of a single hook 305, rotate the second knob 303a. The second knob 303a drives the mounting plate 304 to move through the second threaded rod 303 and the third slider 303b, so that the single hook 305 rises and falls synchronously. When the height of the hook 305 reaches the preset value, the free end of the cable is wrapped around the hook 305, thus realizing the storage of the cable.
