Embodiment
Embodiment:
Structural representation of the present utility model such as Fig. 1, shown in 2, sensitive switch of the present utility model, include support 1, sensitive switch 2, push switch, wherein sensitive switch 2 is fixed in a side of support 1, push switch is fixed in the opposite side of support 1, and the below of push switch is provided with positioning mandril mechanism, wherein push switch comprise by pressing spring 4 and be provided with detent 31 push push rod 3, wherein pushing push rod 3 is sleeved on the slideway 11 that support 1 is provided with, and when pushing push rod 3 and on slideway 11, moving, an end of pushing push rod 3 can contact with the contact 21 that sensitive switch 2 is provided with, be sleeved on the outside of pushing push rod 3 by pressing spring 4, positioning mandril mechanism comprises positioning mandril 6, top stem casing 5, location inner spring 8, location outer spring 9, stopper 7, wherein top stem casing 5 is installed in support 1, the open end 51 of positioning mandril 6 by top stem casing 5 is set in the set hollow cavity 52 of top stem casing 5, and when the contact 21 that an end of pushing push rod 3 and sensitive switch 2 are provided with contacts, positioning mandril 6 can protrude upward the set hollow cavity 52 of top stem casing 5 by the through hole 53 that top stem casing 5 upper ends are provided with and push push rod 3 set detents 31 roof pressure mutually, the open end 51 of top stem casing 5 is provided with stopper 7, location inner spring 8 is installed between the lower end and stopper 7 of positioning mandril 6, the outside of top stem casing 5 also is set with location outer spring 9, one end of location outer spring 9 and an end of support 1 touch, and the other end of location outer spring 9 touches with the location edge 54 that is arranged on top stem casing 5 outsides.
For ease of installing, above-mentioned top stem casing 5 is sleeved in the set sleeve 12 of support 1.In addition, the end of the set sleeve 12 of above-mentioned support 1 is equiped with lid 10.
In the present embodiment, the above-mentioned location edge 54 that is arranged on top stem casing 5 outsides is made with top stem casing 5 one.
In the present embodiment, above-mentioned downward displacement stroke of pushing the degree of depth of the detent 31 that push rod 3 is provided with less than top stem casing 5.
For ease of installing, above-mentioned end of pushing push rod 3 also is provided with top cover 32, touches by an end and the top cover 32 of pressing spring 4, and the end of the slideway 11 that is provided with by the other end and the support 1 of pressing spring 4 touches.In the present embodiment,
Operation principle of the present utility model is as follows: when being in vertical state, top stem casing 5 bottommosts are subjected to the strength on a top, make top stem casing 5 move up, location outer spring 9 is in compressive state, and top stem casing 5 tops also can be subjected to the obstruction of support 1 and can not extend upward always; Positioning mandril 6 can move upward by the passage 51 that bar overlaps on 5, when push switch is in not pressed state, described groove 31 be not in passage 51 directly over, thereby the upper end of positioning mandril 6 top passes passage 51 and upwards withstood and push push rod 3 and can not move upward, and location inner spring 8 then is in compressive state.When push switch is in pressed state, pushing push rod 3 moves right, be in compressive state by pressing spring 4, when pushing push rod 3 and contact with contact 21, groove 31 just be in passage 51 directly over, the resilience force that positioning mandril 6 is located inner spring 8 continues to move upward, with groove 31 buckle mutually, thereby make positioning mandril 6 and push push rod 3 mutual buckles and reach fixing, sensitive switch 2 is in "on" position.
When sensitive switch of the present utility model is toppled over, top stem casing 5 bottoms will lose support, top stem casing 5 moves away from the push switch direction under the effect of compressed location outer spring 9 resilience forces, when pushing up to lid 10, location edge 54 stops, and positioning mandril 6 is also followed top stem casing 5 and disengaging groove 31, push push rod 3 and move right away from contact 21, thereby make sensitive switch 2 be in off-position in the resilience force effect of the spring 4 that is pressed.And sensitive switch is when being in vertical state once more, top stem casing 5 bottoms are subjected to a top power again, make top stem casing 5 and positioning mandril 6 all move up, but when not pushing push switch, push rod 3 contacts that are not pressed as yet of the contact 21 of sensitive switch 2, thereby sensitive switch 2 still is in off-position, and when push switch is in pressed state, pushes push rod 3 and move right to the contact 21, positioning mandril 6 and groove 31 be buckle mutually, make sensitive switch 2 be in "on" position, so circulation.
