Handle mechanism of lifting-pulling rotation trigger switch

Abstract

The invention discloses a handle mechanism of a lifting-pulling rotation trigger switch. The handle mechanism comprises a sleeve (2), a press switch (3), a pull rod A (7), a push rod seat (10), a press switch B (14) and a pull rod B (16), and is characterized in that a cover plate (1) and a torsional spring (18) propping a push knob (19) are arranged in a groove at the top; the pull rod A (7) is arranged in the sleeve (2); the pull rod B (16) is arranged inside the pull rod A (7); a pin A (9) is arranged on the bottom of a spring A (20); the pin A (9) extends into an extending-out groove of the push rod (11) movably arranged in a slide groove of the push rod seat (10) and is abutted by a stop block (8) arranged on the sleeve (2); the press switch A (3) and the press switch B (14) fixed onthe sleeve (2) are respectively provided with a push button A (4) and a push button B (13). The handle mechanism has the characteristics that the structure is compact; the misoperation probability islow; the operation is convenient; the switch switching-on conversion performance reliability is high, and the like.

Description

technical field [0001] The invention belongs to the field of landing gear control handles, and in particular relates to a handle mechanism for lifting and rotating a trigger switch. Background technique [0002] In the traditional handle mechanism for emergency lowering of the landing gear, the large circular surface, the small circular surface and the transitional slope on the pull rod move each other to drive the rocker to realize the work of the button switch, so as to achieve the output of relevant electrical signals when the landing gear is emergency lowered. , but the handle mechanism has problems such as uncompact device structure, large space occupation, high probability of misoperation, poor operation feel, and low reliability when the switch is switched on and off. Contents of the invention [0003] The object of the present invention is to overcome the above disadvantages and provide a handle mechanism for lifting and rotating trigger switches with compact struc...
