Description
Technical field
The present invention relates to a kind of door latch structure, relate in particular to a kind of door lock of washing machine for washing machine cover locking.
Background technology
Door lock of washing machine is for washing machine, particularly tumbling-box washing machine has vital effect, if in use, washing machine cover can arbitrarily be opened, washings not only in washing machine and clothes easily splash and throw away, and child easily opens washing machine cover, contact inside subject device, easily meets accident.
In order to solve the problem, Chinese patent literature CN102094305A discloses a kind of door lock assembly, comprise matrix and join housing, for the keyhole that keeper inserts when housing is provided with and closes, it is corresponding with the keyhole on described housing that matrix is provided with keyhole, described matrix is provided with the lock body with pivot, this lock body has briquetting, latch hook, slewing limit block I and slewing limit block II, the pivot of lock body is provided with revolution torsion spring, matrix is provided with mobile lockplate, back-moving spring I is provided with between this lockplate and housing, lockplate front end contacts with the slewing limit block II of lock body under described back-moving spring I with the effect of revolution torsion spring, matrix has spatial accommodation, back-moving spring II is provided with in this spatial accommodation, one end of back-moving spring II contacts with spatial accommodation, the other end contacts with lockplate, described lockplate has sliding surface, this sliding surface is corresponding with the sliding surface on matrix.
Namely in the door lock assembly described in above-mentioned patent document, at closing time, keeper enters the keyhole of matrix, keeper head applies pressure to lock body briquetting, the pressure that this pressure overcomes revolution torsion spring makes lock body counterclockwise rotate, close lock body one end of lockplate forces lockplate to move to away from lock body direction by the thrust of lock body slewing limit block II, when lock body rotates to certain angle, lockplate can enter the below of lock body slewing limit block II during near lock body one end, lockplate moves near lock body direction under the rebound effect of back-moving spring I, lockplate enters the below of lock body slewing limit block II near lock body one end, now keeper is caught on by latch hook, realization is closed the door, during enabling, keeper produces the power pulling lock body latch hook to turn clockwise, when this power acquires a certain degree, the downforce be applied on lockplate can overcome the spring force of back-moving spring II, the slewing limit block II of lock body turns clockwise, lockplate is pressed towards lower movement near lock body one end, and just move horizontally to the direction away from lock body away from one end of lock body, when keeper pulls lock body to rotate to certain angle, lockplate can depart from from lock body slewing limit block II near lock body one end, deviate from latch hook in keeper, realize opening the door.
But the door lock assembly described in above-mentioned patent document, have the following disadvantages: in this door lock assembly, be by the slewing limit block II of lock body, lockplate near lock body one end, cooperatively interacting between back-moving spring I and back-moving spring II realize catching on of latch hook and deviate from, therefore, require high to the processing assembling of each part, slightly error, may just cannot realize successfully locking completely or locking out, stability is bad, is easily out of order.
Summary of the invention
