The invention provides an electromagnetic release reset device which comprises a shell; an electromagnetic release which is arranged on the shell, and the electromagnetic release is provided with an ejector rod; an ejector rod reset piece, wherein one end, in the length direction, of the ejector rod reset piece is pivoted to the shell while the other end, in the length direction, of the ejector rod reset piece is matched with the ejector rod in position; a handle which is pivoted on the shell in a resettable manner; an operating mechanism which comprises a base frame pivoted on the shell in aresettable manner, a jump pin pivoted on the base frame and matched with the handle in a linkage manner, and a lock catch pivoted on the base frame in a resettable manner and matched with the jump pinin a buckling manner; one side, facing the ejector rod reset piece, of the base frame is provided with a pushing part for enabling the ejector rod reset piece to swing towards the ejector rod. According to the electromagnetic release reset device disclosed in the invention, the electromagnetic tripper can strike the lock catch by virtue of the ejector rod reset piece, so that the lock catch and the jump pin are slid off and unlocked, the base frame can strike the ejector rod by virtue of the ejector rod reset piece in a return process, and therefore the ejector rod retracts to an original position.
Description
technical field [0001] The invention relates to the field of low-voltage electrical appliances, in particular to a reset device for an electromagnetic release. Background technique [0002] The electromagnetic release is an important part of the circuit breaker, which can trip the circuit breaker when the circuit breaks down, so as to protect the safety of the circuit. After the fault is eliminated, the circuit breaker needs to be closed again. At this time, the electromagnetic release needs to be reset, otherwise the circuit breaker will not be able to close. At present, similar structures on the market are relatively complex, costly, require high precision parts, and are difficult to assemble. Contents of the invention [0003] In view of the above-mentioned shortcomings of the prior art, the technical problem to be solved by the present invention is to provide a reset device for an electromagnetic release, the electromagnetic release can hit the lock with the help of t...
