Description
Technical field
The present invention relates to a kind of door latch structure, relates in particular to a kind of door lock of washing machine for washing machine cover locking.
Background technology
Door lock of washing machine particularly has vital effect, if making for washing machine for tumbling-box washing machine
During, washing machine cover can be opened arbitrarily, and not only the washings in washing machine and clothes easily splash and throw away, but also child
Washing machine cover is easily opened, inside subject device is contacted, accident easily occurs.
To solve the above-mentioned problems, Chinese patent literature CN102094305A discloses a kind of door lock assembly, including matrix
And its joined housing, housing are equipped with when closing and are equipped with keyhole and the bolt on the housing for the keyhole of keeper insertion, matrix
Hole corresponds to, and described matrix is equipped with the lock body with pivot, has briquetting, latch hook, slewing limit block I in the lock body and returns
Turn limited block II, revolution torsional spring is provided with the pivot of lock body, matrix is equipped with mobile lockplate, the lockplate and shell
Resetting spring I, revolution of the locking front edge of board under the action of the resetting spring I and revolution torsional spring with lock body are equipped between body
Limited block II is in contact, and has accommodation space on matrix, resetting spring II, one end of resetting spring II are equipped with the accommodation space
Contacted with accommodation space, the other end is contacted with lockplate, has sliding surface, the sliding surface and the cunning on matrix on the lockplate
Dynamic face is corresponding.
I.e. in the door lock assembly described in above patent document, at closing time, keeper enter matrix keyhole, keeper head to
Lock body briquetting applies pressure, which overcomes the pressure of revolution torsional spring to rotate in an anti-clockwise direction lock body, and lockplate leans on
Nearly lock body one end is forced lockplate to be moved to away from lock body direction by the thrust of lock body slewing limit block II, works as lock body
Certain angle is rotated to, when lockplate can enter the lower section of lock body slewing limit block II close to lock body one end, lockplate
Moved under the rebound effect of resetting spring I to close to lock body direction, lockplate is returned close to lock body one end into lock body
Turn the lower section of limited block II, keeper is caught on by latch hook at this time, is realized and is closed the door；Produced during enabling, on keeper and pull lock body latch hook
The power rotated clockwise, when which reaches a certain level, the lower pressure being applied on lockplate can overcome resetting spring II's
Spring force, the slewing limit block II of lock body are rotated clockwise, and lockplate is pressed towards lower movement close to lock body one end, and remote
One end of lock body is just moved horizontally to the direction away from lock body, when keeper pulling lock body rotates to certain angle, locking
Plate can depart from close to lock body one end from lock body slewing limit block II, deviate from keeper in latch hook, realizes and opens the door.
But the door lock assembly described in above patent document, have the following disadvantages：It is to pass through in the door lock assembly
Slewing limit block II, the lockplate of lock body are mutual between lock body one end, resetting spring I and resetting spring II
Coordinate to realize catching on and deviating from for latch hook, therefore, the processing assembling to each part requires high, slightly error, may just can not
Realization is successfully locked or lock out completely, and stability is bad, is easily out of order.
