Abstract
The utility model relates to an up-side-down resisting switch, compising a case. Wherein, the inside of the case is provided with a cavity. The lower direction of the inside of the cavity is provided with a guide groove. A ball arranged in the inside of the cavity is matched with the port of the guide groove. The inside of the guide groove is provided with a lever, whose load bearing end is matched with the ball. The other end of the lever is movably connected with the case. The lower end of the case is provided with a microswitch. The press-button of the microswitch is arranged at the lower end of the lever and matched with the lever. The utility model has the advantages of better instant performance, safe and reliable usage and reasonable structure.
Description
Technical field:
The utility model relates to a kind of electric control switch, particularly a kind of anti-dumping switch that is used on the electrical appliance.
Background technology:
Generally be used for various warm-air driers, electric fan and electric heating oil lamp etc. and need prevent the electrical equipment of toppling over; its anti-dumping switch is to adopt the spring-piece type structure; two shell fragments that are contained on the pedestal are exposed fully externally; use dangerous; and in the electrical equipment toppling process; rely on not contacting of two shell fragments to protect; but because two shell fragments are in disconnection and contact process; slow in one's movements; it is relatively poor to cause switch conduction and the wink that contacts to move property; and two shell fragments easily cause melting welding to connect the phenomenon that does not disconnect in contact or disconnection process, and it is unreliable to work.
Summary of the invention:
The technical problems to be solved in the utility model provides moving good, safe and reliable, the rational in infrastructure anti-dumping switch of property of a kind of wink.
The technical scheme that the utility model solves the problems of the technologies described above is: comprise shell, wherein be provided with cavity in the shell, the below is provided with guide groove in the cavity, be provided with ball in the cavity, ball and guide groove mouth cooperate, and are provided with lever in the guide groove, the load-bearing end of lever and ball cooperate, the lever other end and shell flexibly connect, and the lower end of shell is provided with sensitive switch, and the button of sensitive switch is located at the lower end and and the lever mated of lever.
After the utility model is implemented technique scheme, owing to used the sensitive switch of mature technology, so it is better, safe and reliable wink to move property, owing to used the principle of lever, makes structure more reasonable.
Description of drawings:
Below in conjunction with accompanying drawing embodiment of the present utility model is further described:
Fig. 1 is a structural representation of the present utility model;
Embodiment:
As shown in Figure 1, the utility model comprises shell 1, wherein be provided with cavity 2 in the shell 1, the below is provided with guide groove 3 in the cavity 2, is provided with ball 4 in the cavity, 3 mouthfuls of cooperations of ball 4 and guide groove, be provided with lever 5 in the guide groove 3, the load-bearing end of lever 5 and ball 4 cooperate, and lever 5 other ends and shell 1 flexibly connect, the lower end of shell 1 is provided with sensitive switch 6, and the button 7 of sensitive switch 6 is located at the lower end and and lever 5 cooperations of lever 5.Under normal condition, the action of gravity of ball 4 makes lever 5 compress button 7 in the load-bearing end of lever 5, and this moment, sensitive switch 6 terminals 10 were connected with terminal 11, and sensitive switch 6 is in conducting state; For increasing the opplied moment of ball 4, microsprings 8 can be set above lever 5, can guarantee that like this lever 5 presses button 7, and for increasing the stability of ball 4, can ball support 9 be set at the load-bearing end of lever 5, allow ball 4 directly place on the ball support 9, when the product that uses during to any direction inclination certain angle, ball 4 can fall in the cavity 2, thereby lever 5 is upspring under the resilience force effect of button 7, this moment, the terminal 10 of sensitive switch 6 was connected with terminal 12, and sensitive switch 6 is in cut-off state, thereby the normal circuit of product is disconnected.
