Description
Technical field
The utility model relates to a kind of electric control switch, especially a kind ofly is used to prevent the totally enclosed type anti-dumping switch that shields when electrical equipment is toppled over.
Background technology
Chinese patent 200320120575.4 discloses a kind of anti-dumping switch of shielding when household electrical appliance such as various warm-air driers, electric fan and electric heating installation using oil as medium and other electrical equipment are toppled over of being used for; this switch is a kind of ball-type anti-dumping switch; it mainly comprises the housing of the case formation of two connections, is arranged on sensitive switch and carriage mechanism in the housing.Carriage mechanism is made of pallet, compressing tablet and back-moving spring, its two sides of compressing tablet that supporting is connected in the housing lower chamber join with the contact of back-moving spring and sensitive switch respectively, the other end of compressing tablet is equipped with pallet, and pallet is arranged in the cavity, be contained in spheroid in the upper cavity and fall into and depress pallet in the cavity, compressing tablet is depressed the contact of sensitive switch and is connected circuit.When main frame tilted and falls, with the housing tilt displacement, then pallet was owing to the disengaging of spheroid sets back compressing tablet to spheroid under the effect of its gravity, and sensitive switch moment disconnection reaches and cuts off the electricity supply or the purpose of circuit.Therefore this switch can not be subjected to the influence of external environment factors such as the corrosion of gases such as airborne acid, alkali and air humidity because spheroid, pallet and compressing tablet are arranged in the upper cavity of sealing, can guarantee the wink moving property and the security reliability of use of switch motion.
Summary of the invention
Technical problem to be solved in the utility model is that a kind of totally enclosed type anti-dumping switch that is different from the prior art structure will be provided, and this switch designs is reasonable, and is stable and reliable for performance, can guarantee better the wink of switch motion to move the security reliability of property and use.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: the totally enclosed type anti-dumping switch that the utility model is designed, comprise housing, this housing has sealing and the bottom is upper cavity and the lower chamber and the cavity between upper cavity and lower chamber of bowl-type, ball is housed in the upper cavity, switching device is housed in the lower chamber, be equipped with in the cavity by the transfer bar mechanism of ball action with the control switch break-make, this transfer bar mechanism comprises that one can axially movable push rod and be contained in the back-moving spring on this push rod, push rod corresponding ball wherein, be the disk-like structure that can supply ball to fall into, the other end is corresponding to the movable contact spring in the switching device, movable contact spring is provided with moving contact corresponding to the fixed contact that is located on the fixed touching plate, in ball falls into dish, depress push rod and make the contact on the movable contact spring contact energising with contact on the fixed touching plate.When ball breaks away from the pallet of push rod, then push rod is because the effect of back-moving spring, on move and set back, movable contact spring moment upsprings, contact on the movable contact spring and the contact on the fixed touching plate disengage outage.
Compared with prior art, advantage of the present utility model is: by the variation of ball with the main frame position, make ball fall into the push rod of depressing the band pallet in the cavity of housing, or the cavity of ball disengaging housing makes the push rod of band pallet be in free state, realize the break-make work of switching device and power supply or circuit by the elasticity of movable contact spring, it employs angle is comprehensive.Because the push rod of the ball of action component of the present utility model, band pallet is arranged in the upper cavity of housing of sealing, therefore can not be subjected to the influence of external environment factors such as the corrosion of gases such as airborne acid, alkali and air humidity, can guarantee the moving property of wink of switch motion, safe and reliable, as to improve switch greatly useful life.Anti-dumping switch of the present utility model can be widely used on the electrical equipment such as the liquefier, warmer of various low-voltage low currents.

Embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
In conjunction with Fig. 1, shown in Figure 2, totally enclosed type anti-dumping switch of the present utility model comprises housing 1 and is arranged on housing interior switching device and transfer bar mechanism.Its middle shell 1 is by two case be combined intos, and for ease of quick mounting or dismounting, is respectively equipped with the draw-in groove and the buckle of clamping mutually on two cases.Be formed with upper cavity, lower chamber and the cavity between upper cavity and lower chamber that a sealing and bottom are bowl-type by two cases in conjunction with the housing 1 that constitutes, ball 2 is housed in the upper cavity of housing, ball 2 can roll in upper cavity.
Switching device is contained in the lower chamber of housing 1, moving in the switching device lead in flakes 6 and fixed touching plate 11 be contained in respectively on the relevant position of housing, movingly lead in flakes 6 and all extend in outside the housing with an end of fixed touching plate 11.One end of movable contact spring 56 rivets together with moving leading in flakes, and other end riveted has a moving contact 9.Fixed contact 10 riveteds are on fixed touching plate 11, over against the moving contact 9 of top.
Transfer bar mechanism is contained in the cavity of housing 1, is made of push rod 3, back-moving spring 4 etc., and wherein push rod 3 is a T type member, is contained in the axle bed 7 to move axially.Axle bed 7 is fixed on the clamping plate at housing cavity place.Be contained in push rod 3 one heads on the axle bed corresponding to the movable contact spring in the switching device 5, the other end is corresponding to ball 2, and makes the hypocrateriform structure that can fall into for ball, and the card of pallet is a concaved circular cambered surface.Like this when ball 2 falls in the pallet, push rod 3 is moved down and depress movable contact spring 5, the moving contact 9 on the movable contact spring is contacted with fixed contact 10 on the fixed touching plate, and energized or circuit.Back-moving spring 4 is contained on the push rod 3, and when ball 2 left the pallet of push rod 3, push rod 3 was exactly the effect by this spring 4, on move and set back, 5 moments of movable contact spring are upspring, the contact 9 on the movable contact spring disengages with the contact 10 on the fixed touching plate and cuts off the power supply.And, a back-up ring 8 being housed on the appropriate location of push rod bottom for spacing when moving on the push rod 3, this back-up ring 8 and axle bed 7 are collided and are placed restrictions on the purpose that push rod 3 moves on continuing to play.
Its course of work is as follows: when main frame just often, ball 2 falls in the cavity and depresses push rod 3 under action of gravity, then push rod 3 is depressed movable contact spring 5, anti-dumping switch moment energized and circuit; When main frame tilted or falls, with housing 1 tilt displacement, then push rod 3 was because the disengaging of ball 2 sets back under the effect of back-moving spring 4 ball 2 under the effect of gravity, and the disconnection of upspringing of 5 moments of movable contact spring reaches and cuts off the electricity supply or the purpose of circuit.
