Novel emergency stop switch

Abstract

The invention discloses a novel emergency stop switch, and belongs to the technical field of emergency stop switches. An existing emergency stop switch needs to be reset manually, and in some equipment facing an end user, the emergency stop switch is frequently pressed by mistake, so that the equipment cannot be used normally, and a worker or an operation and maintenance worker needs to speciallyreset the emergency stop switch on site. The device comprises a fixing buckle with a hollow cavity, a top cover capable of rotating relative to the fixing buckle and moving up and down, a spline shaftarranged below the top cover, a shaft shell capable of limiting the stroke of the spline shaft, and a first elastic part capable of driving the top cover to reset. Through continuous exploration andtests, the technical prejudice that an existing emergency stop switch must be reset manually is broken through, the motor assembly can drive the spline shaft to rotate, then the first elastic part drives the spline shaft and the top cover to reset, then the emergency stop switch is reset, equipment can operate in time, the equipment utilization rate is increased, and the operation and maintenancecost is reduced.

Description

technical field [0001] The invention relates to a novel emergency stop switch, belonging to the technical field of emergency stop switches. Background technique [0002] A Chinese patent (publication number CN 201222442Y) discloses a rotary reset emergency stop switch, which includes a housing, a pressing member disposed on the upper end of the housing, a sliding member disposed in the housing, and an electrical device disposed on the lower end of the housing. The pressing part is connected with the top end of the sliding part, the sliding part is slidably connected with the casing, and a spring is arranged between the sliding body and the casing. The housing is circular, and a buckle and a clip corresponding to the buckle are provided between the outer wall of the sliding member and the inner wall of the housing, and the buckle moves along the axial direction and the circumferential direction of the housing relative to the buckle. The invention has the advantages of compac...

Problems solved by technology

[0004] However, the above-mentioned emergency stop switch needs to be manually reset. On some end-user-oriented equipment, such as outdoor electrical cabinets, charging piles and other electrical equipment, the emergency stop switch is often pressed by mistake, resulting in the equipment not working normally. Operation and maintenance personnel go to the site to reset the emergency stop switch

The equipment cannot run in time, which greatly reduces the utilization rate of the equipment and increases the operation and maintenance cost
