Description

Technical Field

[0001] The utility model relates to the field of detection devices, in particular to a detection device for an elevator safety protection switch. Background Art

[0002] The elevator safety protection switch is an important safety device in the elevator. It is used to monitor and control the operating status of the elevator, ensuring that the elevator can stop running in time when a fault or abnormal situation occurs, thereby protecting the safety of passengers and equipment. These safety protection switches are usually distributed in different parts of the elevator, including the machine room, shaft, pit, car and car roof. The elevator safety protection switch needs to be tested with corresponding detection devices before leaving the factory.

[0003] In existing detection devices, when inspecting elevator protection switches, quality inspection staff usually manually press the switch continuously to detect the production quality of the elevator protection switch. However, after the quality inspection staff continuously press the switch manually, the force and frequency of pressing the switch will decrease as the quality inspection staff becomes tired, resulting in a decrease in the detection efficiency of the elevator protection switch.

[0004] Therefore, in view of the above-mentioned quality inspection staff constantly manually pressing the switch to detect the production quality of the elevator protection switch, the strength and frequency of pressing the switch will decay as the quality inspection staff become tired after constantly pressing the switch, resulting in a decrease in the detection efficiency of the elevator protection switch. A detection device for the elevator safety protection switch can be designed, which can fix the protection switch by designing a positioning structure, and then fix the hammering structure above the protection switch through a supporting structure, and continuously hammer the protection switch to solve the above problem. Utility Model Content

[0005] In order to overcome the existing detection device, when inspecting the elevator protection switch, the quality inspection staff usually manually press the switch continuously to detect the production quality of the elevator protection switch. However, after the quality inspection staff continuously presses the switch manually, the strength and frequency of pressing the switch will decrease as the quality inspection staff becomes tired, resulting in a problem of reduced detection efficiency of the elevator protection switch.
