Abstract

The invention discloses a molded case circuit breaker switch-on and switch-off operation mechanical hand which comprises a driving mechanism, a main support and a pin shaft. The pin shaft which is driven by the driving mechanism moves relative to the main support. The pin shaft is provided with a baffle and sleeved with a reset spring. One end of the reset spring is fixed to the main support. Theother end of the reset spring is fixed to the baffle. A movable support is fixed to the pin shaft, and comprises an upper plate, a middle plate and a lower plate in sequence. A rotary pin is arrangedat the end, away from the pin shaft, of the middle plate. The middle of a stirring piece is fixed to the rotary pin. One end of the stirring piece extends out of the movable support. A first force supporting spring is fixed between the lower plate and the other end of the stirring piece. A first spring force adjusting screw is arranged on the upper plate. A second force supporting spring is fixedbetween the lower plate and the other end of the stirring piece. A second spring force adjusting screw is arranged on the lower plate. The applicable place is enlarged, the mechanical hand makes softcontact with a molded case circuit breaker handle with spring compression performance for buffering, and therefore the mechanical damage to the handle is reduced.

Description

technical field [0001] The invention relates to an operating manipulator. Background technique [0002] Molded case circuit breakers generally do not have automatic closing and opening functions, national standards GB14048.1-2006 "Low-voltage switchgear and control equipment Part 1: General" and GB14048.2-2008 "Low-voltage switchgear and control equipment Part 2 : Circuit Breaker "requires the circuit breaker making and breaking capacity test and mechanical life test. Mechanical mechanisms to do the job. [0003] The closing and opening operating mechanism of the existing molded case circuit breaker uses a cylinder to drive the baffle to move up and down to achieve the effect of closing and opening. The use of this mechanism must be equipped with an air source, so the application site is limited. At the same time, the hard contact between the baffle and the handle of the molded case circuit breaker will damage the handle to a certain extent. Contents of the invention ...
