Abstract
The utility model relates to an anti-slant switch which has good instantaneous release performance and secure and reliable operation, and can expand the operation range. The utility model is characterized in that a microswitch is fixed in a U-shaped mounting rack, a bridge plate connected to the side part of the U-shaped mounting rack is arranged between the lower part of a microswitch button and the bottom part of the U-shaped mounting rack, a hanger rod with a dead-weight is got through the U-shaped mounting rack and is positioned at one end of the bridge plate, the dead-weight is inclined to lead the hanger rod to swing to push the bridge plate to be contacted with the microswitch button, thus the slant protection is realized. The utility model can be widely used for a radiator, an electric fan, an electrical oil heater and other household electric appliances which are required to prevent from slanting.
Description
Technical field
The utility model relates to a kind of electric control switch, especially a kind of anti-dumping switch that is used on the household electrical appliance.
Background technology
Generally be used for various warm-air driers; on the household electrical appliance that electric fan and electric heating installation using oil as medium etc. need prevent to topple 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; not only the useful life of switch short, and two shell fragments easily cause melting welding to connect the phenomenon that does not disconnect in contact or disconnection process, it is unreliable to work.Because this kind structure all is the single-pole single-throw(SPST structure, its scope of application is subjected to certain placing restrictions in addition.
Summary of the invention
It is good, safe and reliable that technical problem to be solved in the utility model provides a kind of wink moving property, and can enlarge the anti-dumping switch of the comprehensive type of the scope of application.
The technical scheme that the utility model solves the problems of the technologies described above is: a kind of anti-dumping switch, it is characterized in that: sensitive switch is fixed in the U-shaped installing rack, the bridge plate that is connected U-shaped installing rack sidepiece is arranged between the bottom of the bottom of microswitch push-button and U-shaped installing rack, have the end that the suspension rod of heavily cutting or polish jade with an emery wheel passes the U-shaped installing rack and is positioned at bridge plate, heavily stone roller tilts to make suspension rod swing promotion bridge plate to contact with the button of sensitive switch.
Operation principle of the present utility model is: when main frame just often, the heavily stone roller on the anti-dumping switch vertically downward, suspension rod does not have active force to bridge plate, bridge plate is positioned at the neutral position, anti-dumping switch is in on-state.When main frame tilted and falls, the heavily stone roller on the anti-dumping switch also tilted, and also wallowing motion of the suspension rod that is attached thereto, this moment, suspension rod then promoted bridge plate, remake the button that is used for sensitive switch, made sensitive switch moment disconnection, reach and cut off the electricity supply or the purpose of circuit, and can connect warning device.
After the utility model is implemented technique scheme, owing to utilized the sensitive switch of mature technology, tilt to make the suspension rod swing to promote to be contained in the button work that bridge plate on the U-shaped installing rack is controlled sensitive switch by heavy stone roller, the spring-piece type single-pole single-throw(SPST structure that is exposed has been become the switch that moves the good totally-enclosed single-pole double throw of property wink, not only safe and reliable, can prolong the useful life of switch, but also the scope of application of expansion switch, simultaneously when the bridge plate squeeze buttons, be attended by the sense of touch that click is rattled away, can be widely used in warm-air drier, household electrical appliance such as electric fan and electric heating installation using oil as medium.
Scheme attached explanation
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
Fig. 1 is a structural representation of the present utility model.
Embodiment
Anti-dumping switch as shown in Figure 1, comprise sensitive switch 7, U-shaped installing rack, bridge plate 3, suspension rod 5 and heavily cut or polish jade with an emery wheel 6, sensitive switch 7 is fixedly connected in the U-shaped installing rack, this U-shaped installing rack is made of cover plate 1 and 4 assemblings of L shaped connecting plate, as shown in Figure 1, its cover plate 1 is provided with socket or convex tendon, and links to each other with convex tendon or socket on the L shaped connecting plate 4, or adopting alternate manner to connect, L shaped connecting plate 4 is provided with flanging and the installation slotted eye that is connected with main frame is arranged.The shell fragment of sensitive switch 7 is a closed structure; supporting is connected the bridge plate 3 of U-shaped installing rack sidepiece between the bottom and U-shaped installing rack bottom of sensitive switch 7 buttons 2; one end of suspension rod 5 with heavily cut or polish jade with an emery wheel 6 and be fixedly linked; the other end passes the end that the U-shaped installing rack is positioned at bridge plate 3; when when heavily cutting or polish jade with an emery wheel 6 inclinations, driving suspension rod 5 swings; end promotion bridge plate 3 by suspension rod 5 upwards links to each other with the button 2 of sensitive switch 7, cuts off the electricity supply or circuit, connects warning device and realizes protection.
Claims (2)
