Abstract
The utility model discloses a kind of anti-dumping switch, are related to electrical equipment, which can be mounted on heater, electric heater, and anti-dumping switch connection by the way that the electric wire of electric appliance is connected public pole terminal and NC terminals, is entered circuit by the footing of oil heater.When electric appliance is horizontal positioned, steel ball can push down compression bar connection public pole terminal and NC terminals, electric appliance therefore it is electric, work normally.And when electric appliance is toppled over, steel ball can be rolled to side, and spring will rebound to be subjected to displacement with spring plate, and shrapnel drives compression bar displacement, make public pole terminal and NC terminals breaking, and anti-dumping switch disconnects automatically, and electric appliance is stopped.The anti-dumping switch is ingenious in design, highly reliable, it is ensured that anti-dumping switch can disconnect automatically when electric appliance inclination angle is excessive or puts upside down, using the structure design of monoblock type, microswitch directly with the cover of dumping switch and bottom case is integrated, simplifies production process, saves material.
Description
Technical field
The utility model is related to electrical equipments, relate in particular to a kind of anti-dumping switch.
Background technology
Anti-dumping switch is exactly that vertical electric mounting turns off the switch being stopped in footing, inclination.Overturning-preventing is opened
Pass is designed to use electric appliance safely, existing anti-dumping switch structure be inside there are one similar weight it is the same from
By the metal object of activity and a pair of switches contact, when electric appliance is horizontal positioned, metal object can be by two switch contacts, electricity
Device therefore it is electric, normal work, anti-dumping switch disconnects automatically when electric appliance inclination angle is excessive or puts upside down, and electric appliance is stopped.It is existing
Some anti-dumping switch design tradition, functional reliability is poor, usually will appear the phenomenon that anti-dumping switch fails.
Utility model content
The utility model is ingenious in design mainly solving the technical problems that provide a kind of anti-dumping switch, highly reliable, really
The anti-dumping switch when electric appliance inclination angle is excessive or puts upside down is protected to disconnect automatically.
To achieve the above object, the utility model provides following technical solution：
The anti-dumping switch includes the bottom case and cover that are connected by screw, and bottom case knead dough, which covers, is equipped with public pole terminal
With NC terminals, bottom case and cover are internally provided with the steel ball of spheroidal, and when cover is located at right over bottom case, steel ball pushes down compression bar connection
Public pole terminal and NC terminals, and shrapnel is connect respectively with compression bar and spring.
As advanced optimizing for the technical program, the bottom case and cover are manufactured by engineering plastics.
As advanced optimizing for the technical program, the steel ball, shrapnel, spring are by stainless steel making.
As advanced optimizing for the technical program, the public pole terminal, NC terminals, compression bar are manufactured by copper alloy.
It is using the advantageous effect of above technical scheme：The anti-dumping switch can be mounted on heater, electric heater, oil heater
Anti-dumping switch connection by the way that the electric wire of electric appliance is connected public pole terminal and NC terminals, is entered circuit by footing.Work as electric appliance
When horizontal positioned, steel ball can push down compression bar connection public pole terminal and NC terminals, electric appliance therefore it is electric, work normally.And when electricity
Device is toppled over, and steel ball can be rolled to side, and the spring band spring plate that will rebound is subjected to displacement, and shrapnel drives compression bar displacement, allows public pole
Terminal and the open circuit of NC terminals, anti-dumping switch disconnect automatically, and electric appliance is stopped.The anti-dumping switch is ingenious in design, reliability
By force, it is ensured that anti-dumping switch can disconnect automatically when electric appliance inclination angle is excessive or puts upside down, using the structure design of monoblock type, by fine motion
Switch is directly integrated with the cover of dumping switch and bottom case, simplifies production process, saves material.

Specific embodiment
The preferred embodiment of the utility model anti-dumping switch is described in detail below in conjunction with the accompanying drawings.
Fig. 1, Fig. 2 and Fig. 3 show the specific embodiment of the utility model anti-dumping switch：
With reference to Fig. 1, Fig. 2 and Fig. 3, which includes the bottom case 1 being connected by screw and cover 2,1 knead dough of bottom case
Public pole terminal 5 and NC terminals 6 are installed, bottom case 1 and cover 2 are internally provided with the steel ball 3 of spheroidal, and cover 2 is located at bottom on lid 2
During 1 surface of shell, steel ball 3 pushes down compression bar 4 and connects public pole terminal 5 and NC terminals 6, and shrapnel 7 respectively with compression bar 4 and spring 8
Connection.
Bottom case 1 and cover 2 are manufactured by engineering plastics, sturdy and durable, and insulation effect is good, can be anticreep, corrosion resistant
Corrosion can good, low cost.Steel ball 3, shrapnel 7, spring 8 are by stainless steel making, sturdy and durable, corrosion resistance and good, elasticity
Well.Public pole terminal 5, NC terminals 6, compression bar 4 are manufactured by copper alloy, and resistance is small, conducts electricity very well.
The anti-dumping switch can be mounted on heater, electric heater, the footing of oil heater, by the way that the electric wire connection of electric appliance is public
Anti-dumping switch connection is entered circuit by extreme 5 and NC of son terminals 6.When electric appliance is horizontal positioned, steel ball 3 can push down compression bar 4
Connect public pole terminal 5 and NC terminals 6, electric appliance therefore it is electric, work normally.And when electric appliance is toppled over, steel ball 3 can be rolled to side,
Spring 8 will rebound to be subjected to displacement with spring plate 7, and shrapnel 7 drives compression bar 4 to shift, and makes public pole terminal 5 and NC terminals 6 breaking,
Anti-dumping switch disconnects automatically, and electric appliance is stopped.The anti-dumping switch is ingenious in design, highly reliable, it is ensured that when electric appliance inclination angle
It is excessive or anti-dumping switch can disconnect automatically when putting upside down.
Above is only the preferred embodiment of the utility model, it is noted that for those of ordinary skill in the art
For, under the premise of not departing from the utility model and creating design, various modifications and improvements can be made, these belong to this
The protection domain of utility model.
