Description

Anti-dumping switch
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 two cavitys up and down in the shell, be provided with guide groove up and down between cavity, be provided with ball in the upper plenum, ball and guide groove mouth cooperate, and following cavity is provided with the fine motion beginning, be provided with the ball support in the guide groove, the load-bearing end of lever and ball support cooperate, and the lever other end is connected with the fine motion beginning, 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:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of a certain user mode of the utility model.
Embodiment:
Below in conjunction with accompanying drawing embodiment of the present utility model is further described:
As shown in Figure 1, the utility model comprises shell 1, wherein be provided with two cavitys up and down in the shell 1, be provided with guide groove up and down between cavity, be provided with ball 3 in the upper plenum 2, ball 3 and guide groove mouth cooperate, following cavity is provided with fine motion beginning 7, is provided with ball support 4 in the guide groove, and the load-bearing end of lever 5 and ball support 4 cooperate, lever 5 other ends are connected with fine motion beginning 7, and the button 6 of sensitive switch 7 is located at the lower end and and lever 5 cooperations of lever 5.Under normal condition, the action of gravity of ball 3 makes lever 5 compress button 6 in the load-bearing end of lever 5, and this moment, sensitive switch 7 was in conducting state; When the product that uses during to any direction inclination certain angle, ball 3 can fall in the upper plenum 2, thereby lever 5 is upspring under the resilience force effect of button 6, and this moment, sensitive switch 7 was in cut-off state, thereby the normal circuit of product is disconnected.
