Description

Technical Field

[0001] This invention belongs to the field of testing equipment technology, and specifically discloses a switch cabinet handle testing device. Background Technology

[0002] To facilitate operation of molded case circuit breakers (MCCBs), a rotary handle is installed on the MCCB cabinet. Since MCCBs play a safety protection role during circuit maintenance, to prevent incorrect operation by operators using the rotary handle, the handle needs to be tested before leaving the factory. Currently available testing devices for rotary handles typically include a rotating structure and a circuit detection structure. In actual use, the MCCB is connected to the circuit detection structure and power supply. The rotary handle is connected to the rotating structure. Then, the control terminal of the MCCB is connected to the rotating end of the rotary handle. Rotating the handle activates the control terminal of the MCCB, thereby controlling the opening and closing of the MCCB circuit. This allows for the determination of whether the rotary handle's direction is accurately aligned to the designated workstation.

[0003] However, while this testing equipment does achieve good results in detecting rotary handles in actual use, it still has some shortcomings. For example, existing rotary handle detection devices typically rely on human observation to determine whether the rotating end of the rotary handle driven by the rotating structure has reached the indicated position. Subsequently, the control circuit detects the circuit of the molded case circuit breaker through the control terminal, thereby inferring whether the rotary handle's pointing position is accurate. However, human observation is prone to visual fatigue, and relying on human observation requires significant manpower, which also reduces the detection efficiency of the rotary handle. This makes it difficult for workers to determine whether the rotating end of the rotary handle has reached the indicated position through the testing equipment, thus hindering the accurate detection of the rotary handle's pointing position by the testing equipment. Summary of the Invention

[0009] In the above technical solution, further, a plug-in pipe is fixed on the abutting air bag, the plug-in pipe is sleeved on the rotating rod, and the plug-in pipe penetrates the abutting plate.

[0010] In the above technical solution, further, a plug-in ring is fixed on one side of the abutting air bag close to the abutting plate, the plug-in ring is clamped with the abutting plate, and the plug-in ring has elasticity.

[0011] In the above technical solution, further, the driving structure comprises a transmission motor, a mounting seat is fixed on the outer wall of the transmission motor, the first electric sliding rail is also fixed on the mounting seat, a clamping jaw is fixed on the output shaft of the transmission motor, and the clamping jaw clamps the handle component.
