Embodiment 1
[0043] A specific embodiment of the present invention discloses an action switch with high locking reliability, including: an electromagnetic system, a release device 6, a linkage mechanism, a locking piece 2, a conductive column and a housing structure, such as figure 1 , figure 2 shown.
[0044] The link mechanism includes: a handle 1 , a first transmission piece 3 , a second transmission piece 4 and a conductive piece 5 .
[0045] Specifically, the handle 1 passes through the first hinge axis O 1 It is hingedly fixed with the housing 9 of the switch, and the handle 1 can be connected with the first hinge axis O 1Rotate relative to the housing 9 as a center. The hinged part of the handle 1 and the first transmission piece 3 is used as a part of the linkage mechanism, and the extended end of the handle 1 is used as a switch lever.
[0046] The first transmission piece 3 and the handle 1 pass through the second hinge axis O 2 Hinged, the second transmission piece 4 and t...
Embodiment 2
[0069] This embodiment provides a method for turning on and off the action switch in Embodiment 1, and the specific steps include:
[0070]In the initial state, the locking piece 2 locks the first transmission piece 3 and the second transmission piece 4, and the first transmission piece 3, the second transmission piece 4 and the locking piece 2 are combined into a whole, that is, the transmission piece unit; the handle 1, the transmission piece The sheet unit, the conductive sheet 5 and the housing 9 form a crank rocker mechanism, the handle 1 is used as a crank, and the conductive sheet 5 is used as a rocker; 10 In the separated state, the handle 1 is in the closed position (initial position).
[0071] Specifically, when the locking piece 2 locks the first transmission piece 3 and the second transmission piece 4, the second hinge axis O 2 , the third hinge axis O 3 and the fourth articulation axis O 4 Located on the same straight line, and limited by the locking platform 2...

Abstract
The invention relates to an action switch with high locking reliability and a method for turning it on and off, belonging to the field of action switches, and solves the problem of unreliable locking or even failure after long-term use or in mechanical environments such as vibration. The handle, the transmission piece unit, the conductive piece and the housing of the present invention constitute a crank rocker mechanism, the up and down movement of the contact end of the conductive piece is realized by the swing of the handle, and the handle and the conductive piece are hingedly installed with the housing; the transmission piece unit includes: locking piece, the first transmission piece and the second transmission piece; the handle, the first transmission piece, the second transmission piece and the conductive piece are hinged sequentially; the locking piece is used to lock the first transmission piece and the second transmission piece as a whole. The second conductive column, the electromagnetic unit, and the conductive sheet are connected by wires, and the other end of the conductive sheet can be in contact with or separated from the first conductive column to realize circuit connection and disconnection. When an overload current occurs, the electromagnetic unit can turn the transmission sheet The unit is unlocked for disconnection.
Description
technical field [0001] The invention relates to the technical field of action switches, in particular to an action switch with high locking reliability and a method for turning it on and off. Background technique [0002] Domestic electromagnetic circuit breakers are used more and more widely, and the demand is increasing. However, due to the complex structure of electromagnetic circuit breakers, the difficulty of electrical control technology, the high requirements for parts processing and production, and the relatively short development cycle of domestic electromagnetic circuit breakers, The processing technology and guarantee technology of key parts are not mature, the use time is short, the quantity is relatively small, the verification is not sufficient, etc., there are still hidden defects, and there are problems of unreliable locking during the user's use, and the unreliable locking of electromagnetic circuit breakers is serious. Affecting the development progress of my...
