Embodiment 1

[0043] Figure 1-7An operating mechanism for a rotary switch of the first configuration of the present invention is shown.

[0044] Such as figure 1 with 2 As shown, the operating mechanism for the rotary switch in Embodiment 1 includes a rotary positioning member 1, a movable frame 5 and a motion conversion mechanism, wherein;

[0045] The rotating positioning member 1 includes a switch opening positioning recess point 2 and a switch connecting positioning recess point 3 formed on the outer peripheral surface of the rotating positioning member 1 with a continuous curved surface transition, and a positioning recess point 2 with the switch opening positioning recess point or the switch connecting positioning recess point. Point 3 cooperates with the elastic limiter 4 for positioning the rotating positioning member; the movable frame 5 can cooperate with the moving contact frame of the switch main body of the rotary switch when the operating mechanism is installed in the rotar...

Embodiment 2

[0062] In the second embodiment, if Figure 8-10 As shown, the motion conversion mechanism includes a high-position wheel 15 and a low-position wheel 16, a high-position surface 17 and a low-position surface 18, wherein,

[0063] The high-position wheel 15 and the low-position wheel 16 are arranged perpendicularly to each other, and are formed on the rotation positioning member 1 along the axial direction of the rotation positioning member 1 and are located below the switch-off positioning recess 2 and the switch-on positioning recess 3; the high-position surface 17 and The low-level surface 18 is formed on the movable frame 5, and cooperates with the high-position wheel 15 and the low-position wheel 16 respectively; wherein, the radius R2 from the high-position wheel 15 to the axis of the rotating positioning member 1 is greater than the distance L2 from the high-position surface 17 to the center of the movable frame 5, and the low position The radius R1 from the wheel 16 to ...

Embodiment 3

[0069] In the third embodiment, if Figure 11-13 As shown, the motion conversion mechanism includes a limit track 22, a contact body 25 and a movable frame spring 26, wherein,

[0070] The limiting track 22 is formed in the form of a curved surface in a continuous transition on the side of the rotating positioning member 1 facing the movable frame 5, and includes a limiting high point 23 and a limiting low point 24 arranged perpendicular to each other and having a height difference; a contact body 25 It is arranged on one end of the movable frame 5, and can slide on the limit track 22 when the rotary positioning member 1 rotates, so as to cooperate with the limit high point 23 or the limit low point 24; and one end of the movable frame spring 26 is connected with the movable frame 5 connection, and the other end can be connected to the switch main body 31.

[0071] In this way, if Figure 13 As shown, when the contact body 25 cooperates with the limit high point 23, the mova...

Abstract

The invention discloses an operating mechanism for a rotating switch. The operating mechanism comprises a rotating positioning piece (1), a movable frame (5) and a motion conversion mechanism, wherein the rotating positioning piece comprises switch switching-off positioning concave spots (2) and switch switching-on positioning concave spots (3) which are formed on the peripheral surface of the rotating positioning piece (1) through continuous curved surface transition and elastic limit pieces (4) which are matched with the switch switching-off positioning concave spots (2) or the switch switching-on positioning concave spots (3) to implement the positioning of the rotating positioning piece; the movable frame can be matched with a movable contract frame of a switch main body; and the motion conversion mechanism is matched with the rotating positioning piece (1) and the movable frame (5) to convert the rotation of the rotating positioning piece into the swinging of the movable frame (5) to fulfill the aim of driving the contact and separation of a moving contact and a stationary contact of the switch main body through the movable contact frame, accordingly an electric arc between the contacts can be avoided effectively, the reliability of matching can be ensured effectively, and the reasonable layout and sensitive movement of the operating mechanism can also be ensured.

Description

technical field [0001] The invention belongs to the technical field of electrical protection equipment, and in particular relates to an operating mechanism for a rotary switch and a rotary switch with the operating mechanism. Background technique [0002] The existing switchgear, especially the wall switch, generally realizes the connection and disconnection of the switch circuit by pressing the button and swinging the button up and down. The swing angle of the button is about 15°. However, this wall switch, especially a wall switch with relatively small buttons, will have insensitive button action after a period of actual use, making the switch move slowly when swinging, or even jammed, etc., so that the switch contacts are easy to Arcing or welding occurs, which affects the safe use of the device. [0003] For this reason, Chinese patent document CN201311848Y discloses a kind of rotary switch, comprises a rotary switch box and a knob assembly rotatably installed in the ro...
