Description
Technical field
The utility model relates to a kind of door lock, especially a kind of door lock of washing machine.
Background technology.
Usually, the front of tumbling-box washing machine has one to be used to drop into and take out and to want washed door, if being in the suds, opened unintentionally at door, washing agent, washings and the clothes that will wash will be gushed out to the outside of door and the floor of making dirty, therefore, the set door of tumbling-box washing machine place is equipped with one and is used for preventing the door lock that a quilt is opened unintentionally.This door lock is provided with press button, when press button is applied pressing operation, is delivered to the mechanism of closing the door of door interlock switch by pull bar, and door-opening mechanism affacts the mechanism of closing the door that links with it, the mechanism of closing the door is rotated or moves, thereby gate is opened.The tumbling-box washing machine door lock generally comprise housing and join lid, housing is provided with electromagnet, the electromagnet front end is associated with armature, and armature and slippage brake block link, and the slippage brake block is provided with location/reseting groove platform correspondence, lid is provided with a lockhole that inserts for dead bolt when closing, also be provided with lock bolt on the lid, the lock bolt front end is provided with back-moving spring, and it is corresponding with projection on the slippage brake block that lock bolt is provided with projection, also be provided with the skewback structure on the lock bolt, the skewback structure links with the pull bar that opens the door.
At present, generally be not provided with the protection mechanism that opens the door on the door lock of tumbling-box washing machine, when the power on the pull bar is excessive, can make door lock cause damage.For how to prevent door lock when opening the door because of stressed excessive being damaged; part washing machine manufacturer has increased the stroke design in the design of button; and because the door interlock switch required precision is higher; the washing machine fit tolerance of opening the door between pull bar and button and the door interlock switch is bigger; can be opened in order to ensure gate; that stroke need be set is more needed than opening the door, stroke more greatly; for door lock the better protect effect is arranged like this, also have the part washing machine between button and door lock pull bar, to be provided with buffer gears such as spring.Although yet each has something to recommend him at the protection mechanism that opens the door, all have different problems, or a complex structure, or use inconvenient, perhaps function singleness, perhaps cost is higher or the like.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of inside to contain the washing machine door lock protection mechanism that opens the door, that also door lock is shielded when washing machine button stroke is excessive.
The technical scheme that its technical problem that solves the utility model adopts is: the washing machine door lock comprise housing and join lid; housing is provided with electromagnet; the electromagnet front end is associated with armature; armature and slippage brake block link; the slippage brake block is provided with location/reseting groove platform structure and projection; be provided with back-moving spring and pilot pin between slippage brake block and the housing; pilot pin is corresponding with the location/reseting groove platform of slippage brake block; lid is provided with a lockhole that inserts for dead bolt when closing; also be provided with lock bolt on the lid and the pull bar that opens the door; the lock bolt front end is provided with the back-moving spring that links with housing; it is corresponding with projection on the slippage brake block that lock bolt is provided with projection; also be provided with the skewback structure on the lock bolt; the skewback structure links with the pull bar that opens the door, and it is characterized in that: the described pull bar that opens the door is provided with slippage slot, and lid is provided with and the corresponding limited block of slippage slot; slippage slot forms sliding and position limitation with limited block and cooperates, and forms the protection mechanism that opens the door.
Adopt technique scheme, the impulse force that the washing machine door lock is produced when in running order plays and disperses and the buffering effect, prevents that door lock from being destroyed by excessive pulling force.
Of the present utility modelly further be set to: it is the force side that the described pull bar that opens the door is exposed to the outer end of door lock, the pull bar periphery wall upper edge pull bar that opens the door is axially arranged with slippage slot, slippage slot is near the cell wall place opening of force side, described limited block is a cuboid, limited block is positioned on the pull bar movement locus, limited block passes the slippage slot openend, and slippage slot forms sliding and position limitation with limited block and cooperates
Adopt technique scheme, can better realize the defencive function of door lock, the door lock manufacturing requirements is simpler, and production cost is cheaper.
Of the present utility modelly further be set to again: also be provided with limited block on the described housing, corresponding with the limited block on the lid, and form sliding and position limitation with slippage slot and cooperate.
Adopt technique scheme, the equal clamshell doors pull bar of housing and lid plays barrier effect, further disperses to open the door the suffered power of pull bar, strengthens the protective effect for door lock.
