Fig. 7 B corresponds to the blast installation diagram of Fig. 7 A.
Fig. 8 A illustrates, when cam 302 is under the promotion of external force (as user promotes electric equipment door) From unlocking condition to blocking rotate time, sliding pin 316 in heart-shaped gathering sill 314 from original position A Moving process to end position C.As shown in Figure 8 A, when sliding pin 316 is in heart-shaped gathering sill 314 Original position A time, electric equipment door (not shown) is in door opening state, when external force promote electrical equipment set When standby door progressively closes off, the gate stop 107 being arranged on electric equipment door gradually passes through door lock hole 105, enters Enter the opening 308 of the head of cam 302, and promote cam 302 to rotate counterclockwise, thus cam 302 drive sliding pin 316 along heart-shaped gathering sill (i.e. positioner) 314 from heart-shaped gathering sill 314 Beginning position A gradually shifts to the first bottom position B of heart-shaped gathering sill 314, and meanwhile cam 302 is inverse Hour hands are rotated through the cell wall 337 of its vertical shape and drive the first stress section 323. of torsion spring 3121To torsion spring 312 apply revolving force, make torsion spring 312 be in the state of rotatably compressing, and make torsion spring 312 accumulate potential energy. When cam 302 arrives blocking from unlocking condition, cam 302 correspondingly drives sliding pin 316 to arrive First bottom position B of heart-shaped gathering sill 314.When external force disappears, torsion spring 312 returns rotation clockwise Turning certain angle, thus torsion spring 312 discharges certain potential energy, it is little that gate stop 107 is return one by torsion spring 312 Segment distance.Owing to the bias force of torsion spring 312 is applied to the angular compliance heart gathering sill 314 of sliding pin 316 The angle of the first bottom position B so that sliding pin 316 has been pulled to heart from the first bottom position B and has led To keyed end (end position) C of groove.Because keyed end C is the recess of triangle, and torsion spring The bias force of 312 acts on jointly, so sliding pin 316 is fixed on keyed end C, now torsion spring 312 and Cam 302 just can not continue to turn clockwise, and is correspondingly rested on locked position of coupler;Meanwhile, cam The cam hook 304 of 302 is stretched and has been caught on gate stop 107 (see Fig. 6) in the door stop hole 109 of gate stop 107, Thus gate stop 107 has also been kept at locked position of coupler.It should be noted that and release on torsion spring 312 After certain potential energy, torsion spring 312 is still within the state compressed, because sliding pin 316 is fixed on Keyed end C.
When cam 302 and gate stop 107 are maintained at locked position of coupler, as below in conjunction with Fig. 9 B institute in detail Stating, slide block 902 can move to the direction of cam 302, and inserts the bottom of cam 302 (see figure 9B).Now, if user presses the start key on electric equipment (such as washing machine), then door lock drives Dynamic box 212 can stretch out dead bolt (not shown) to be blocked slide block 902, makes the slide block 902 cannot be from cam The bottom of 302 is return, thus cam 302 and gate stop 107 are locked in locked position of coupler further, and then makes The door of electric equipment is lockable.
And when cam 302 and gate stop 107 are maintained at locked position of coupler, if user does not press electricity Start key on device equipment (such as washing machine), door lock drives box 212 just will not stretch out dead bolt by slide block 902 block, now, as being described in detail below in conjunction with Fig. 8 B, if promoting electric equipment by external force Door, then can realize opening of electric equipment door.
Fig. 8 B illustrates, when cam 302 external force (as user promote electric equipment door) promotion under from Blocking when unlocking condition rotates, sliding pin 316 in heart-shaped gathering sill 314 from end position C to The moving process of original position A.Assume complete (the laundry flow process such as washing machine of now electric equipment work Terminate), door lock drives box 212 to retract dead bolt (not shown), discharges the lock being driven box 212 by door lock The slide block 902 that tongue blocks, thus discharge electric equipment door (it may be noted that now the door of electric equipment is still It is maintained at locked position of coupler by cam 302 and gate stop 107, and is not switched on).
Now, if user promotes the door (not shown) of electric equipment, it is stuck in the head of cam 302 Opening 308 in gate stop 107 promote cam 302 to rotate counterclockwise, thus cam 302 drives sliding pin 316 shift to heart-shaped gathering sill 314 along heart-shaped gathering sill 314 from the keyed end C of heart-shaped gathering sill 314 The second bottom position D.Owing to the angle of keyed end C is arranged so that sliding pin 316 moves from keyed end C The irrevocable first bottom position B to the second bottom position D.
When external force disappears, driving cam 302 is turned clockwise by the potential energy on torsion spring 312, drives sliding Pin 316 moves to the start bit of heart-shaped gathering sill 314 from the second bottom position D of heart-shaped gathering sill 314 Put A, so that cam 302 returns to unlocking condition;Meanwhile, under the driving of torsion spring 312, up time The cam 302 that pin rotates also is released being inserted into the slide block 902 bottom it (see Fig. 9 A) bottom it, And ejected from door lock hole 105 by gate stop 107, thus electric equipment door is opened.
It should be noted that the door of electric equipment is typically to rely on hinge to be installed on electric equipment, its rotation When turning produce resistance the least, and as Fig. 9 A, 9B will shown in, connection sliding block 902 afterbody And promote the thrust of sliding block spring 906 that slide block 902 removes to prop up cam 302 the least, and it is used for driving The turning power of the torsion spring 312 that cam 302 turns clockwise is the biggest, therefore, relies on returning of torsion spring 312 Turn power, be to be enough to drive cam 302 to release being inserted into the slide block 902 bottom cam 302 bottom it (see Fig. 9 A), and gate stop 107 is ejected from door lock hole 105, thus open electric equipment door. simultaneously 's.
Fig. 9 A illustrates when cam 302 is in unlocking condition, the position of slide block 902 and with cam 302 Mutual relation, wherein figure (a) is axonometric chart, and figure (b) be to scheme the cam 302 in (a) and a left side for slide block 902 View.As shown in Figure 9 A, the head 902. of now slide block 9021Blocked by cam 302, be not inserted into The bottom of cam 302, meanwhile, connects door lock shell 102 and the afterbody 902. of slide block 902 respectively2Slide block Spring 906 is also at compacted state.
Fig. 9 B illustrates when cam 302 is in blocking, the position of slide block 902 and with cam 302 Mutual relation, wherein figure (a) is axonometric chart, and figure (b) be to scheme the cam 302 in (a) and a left side for slide block 902 View.As shown in Figure 9 B, rotate to locked position of coupler, slide block 902 from lockset position of coupler due to cam 302 Head 902.1No longer being blocked by cam 302, the most compacted sliding block spring 906 discharges potential energy, drives Make slide block 902 move to the direction of cam 302, and insert the bottom of cam 302.
And when cam 302 turns to unlocking condition (as shown in Figure 9 A) from blocking, now at torsion spring Under the driving of 312, cam 302 turns clockwise, and acts on the head 902. of slide block 9021(slide block The head 902. of 9021Side is hypotenuse structure), thus the slide block 902 bottom cam 302 will be inserted into Releasing from the bottom of cam 302, sliding block spring 906 is in compacted state the most again.
Figure 10 is door lock 100 shown in Fig. 1 and the installation diagram of gate stop 107, and illustrates slide block further 902 with the details of the relation that cooperates of cam mechanism 214 cam 302.As shown in Figure 10, slide block 902 can move back and forth relative to the side of cam 302, or insert the bottom of cam 302 (when cam 302 When being in locked position of coupler), or exit from the bottom of cam 302 (when cam 302 is shifted to from locked position of coupler During lockset position of coupler).
