Detailed description of the invention
With embodiment, the present invention is described in further detail below in conjunction with the accompanying drawings.
As shown in Figures 1 to 3, a kind of drawer unit door lock assembly, including the latch hook support 3 being arranged at inside drawer door-plate 1 be arranged at the sliding support 5 inside drawer side 2,
The groove structure 4 that described latch hook support 3 mainly be arranged in parallel with described drawer side 2, offers downwards, chamfered below described groove structure 4 end, in ramp structure；Described latch hook support 3 has 2 groups, often corresponding 2 groove structures 4 of group, multiple clamping, more closely safety.
Described sliding support 5 is fixed on described drawer side 2 with coordinating of limiting rivet 7 by spring 6, can move up and down reset；Lubricant can be smeared between sliding support 5 and drawer side 2 contact surface；Described spring 6 is arranged at the top of described sliding support 5, and its one end is connected fixing with drawer side 2, and the other end is connected fixing with sliding support 5；Being provided with the square groove 11 accommodating described spring on described drawer side 2, square groove 11 length is not less than the maximum elongation length of the spring 6 during using；Being provided with two the oval holes 12 being distributed up and down on described sliding support 5, two described limiting rivets 7 are each passed through described oval hole 12 and are fixed on described drawer side 2 so that described sliding support 5 can slide by relative limit rivet 7.
Described sliding support 5 integrated setting has the mouth 8 coordinating clamping with described groove structure 4；Described mouth 8 quantity is identical with groove structure 4, has 4, spaced apart.
At described drawer side 2 edge, integrated setting has the limiting plate 13 parallel with described drawer door-plate 1, and on described limiting plate 13, corresponding described groove structure 4 is provided with for interting the breach 14 of groove structure 4.
Forming projective structure 9, relevant position in described sliding support 5 bottom, offer slotted eye 10 on described drawer side 2, slotted eye 10 forming part is blocked by projective structure 9, and both coordinate for opening door lock.
As it is shown in figure 5, offer the circular hole 15 for emergency opening drawer unit in described drawer door-plate 1 front, it is edge on 5 mouths 8 of described sliding support in corresponding circular hole 15；Described circular hole 15 plastic stopper blocks, and regular situation circular hole 15 is in closed state.
The work process of door lock assembly:
Closing in front of the door, under the effect of spring 6, sliding support 5 is in position on the upper side (see kinestate a)；
When door pushes away inwardly, the front end protrusion position of latch hook support 3 groove structure 4 is entered by a mouth 8 (see Fig. 4 a)；After the slope of groove structure 4 is pressed on 5 mouths 8 of sliding support, sliding support 5 will pressurized and move down.Along with door continues to push inward, the protruding part of groove structure 4 enters more and more deeper.(see Fig. 4 b).When door pushes inward (i.e. door closes and puts in place) again, a mouth 8 of sliding support 5 can enter in the groove top of groove structure 4, and on the sliding support 5 now originally pressed, shifting, spring 6 bounce back.(see Fig. 4 c).
Groove structure 4 uses approximate right angle in this invention, when after latch hook support 3 with sliding support 5 clamping, in any case level pushes, pulling all to make it separately.Meanwhile, this invention comprises many places and props up the synchronization clamping of mouth and groove.Ensure that the reliable locking effect of door.
To unlock, i.e. open door, have two kinds of methods:
The first is for door opening method under normal circumstances: opens drawer door structure and arranges drawer side surface.Open the front of drawer door must be pulled out from cabinet by drawer, it ensures that the safety of this door lock assembly.In drawer right, with the common instrument such as hands or bottle opener, by slotted eye 10 sliding support 5 protruded above structure 9 down by, sliding support 5 moves down, and a mouth 8 out, draws drawer door from groove structure 4 the most outwardly, and door can be opened.
The second is unblock in emergency circumstances: when drawer door is in the case of accident, it is impossible to when opening the door by first method, can use emergency release method.Take off plastic stopper with instrument, use elongate tool by edge on a mouth 8 corresponding on 15 times pressure internal slide supports 5 of circular hole, sliding support 5 is pressed down, sliding support 5 moves down, propping up mouth 8 and be out the groove structure 4 of sliding support 5, now pull drawer door-plate 1, door can be opened.
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, all any amendment, equivalent and improvement etc. made within the spirit and principles in the present invention, should be included within the scope of the present invention.
