Cabinet is very extensive in routine use, and particularly the file cabinet drawer of unit is a lot, need to be equipped with corresponding many lock and key, and also need to take good care of correspondingly; In reality, also have adopt cant board cover all drawers then lock settle, but outward appearance is indecency, the interlock built-in lock device of described a kind of cabinet drawer can address this problem easily.
Utility model content
In order to address the above problem, the utility model provides a kind of interlock built-in lock device of cabinet drawer, and the rear plate by lockhole design at drawer, is used safety; Because reduced many latch fittings, make outward appearance cleaner and tidier again.
The scheme that the utility model adopts is:
The interlock built-in lock device of described a kind of cabinet drawer mainly consists of lower drawer, upper drawer, cabinet riser, cabinet crosspiece, dead bolt, lockhole, connecting rod, rotating shaft, spring, described lower drawer and described upper drawer all have drawer backboard, described dead bolt is connected by described rotating shaft is vertical with described connecting rod, described rotating shaft is supported on described cabinet crosspiece rotationally, described both ends of the spring connects respectively described cabinet riser and described connecting rod, described lockhole is positioned at described drawer backboard, and described lockhole matches with described dead bolt.Designing requirement can just in time be compressed to the limit by described spring when described lower drawer is shut, and at this moment described dead bolt catches on described lockhole, has pinned from behind described upper drawer.This device arranges one between every two upper and lower drawers, and each device not on a longitudinal straight line, in one group of drawer from top to bottom, only need fill a drawer-lock at a bottom drawer mutually.
The beneficial effects of the utility model are:
The interlock built-in lock device structure of described a kind of cabinet drawer rationally, can reduce the usage quantity of latch fitting and make cabinet outward appearance cleaner and tidier, and built-in lock is also a kind of dual fail-safe.
Accompanying drawing explanation
Below in conjunction with figure of the present utility model, further illustrate:
Fig. 1 is schematic diagram when drawer is not closed completely under the interlock built-in lock device of described a kind of cabinet drawer;
Fig. 2 is schematic diagram when drawer is closed under the interlock built-in lock device of described a kind of cabinet drawer;
Fig. 3 is described drawer backboard front schematic view.
In figure, 1. play drawer, 2. go up drawer, 3. dead bolt, 4. drawer backboard, 5. cabinet riser, 6. cabinet crosspiece, 7. rotating shaft, 8. spring, 9. connecting rod, 10. lockhole.
The specific embodiment
As Fig. 1 schematic diagram when drawer is not closed completely under a kind of interlock built-in lock device of cabinet drawer as described in being, now described upper drawer is not lockable.
As Fig. 2 schematic diagram when drawer is closed under a kind of interlock built-in lock device of cabinet drawer as described in being, now described upper drawer is lockable.The interlock built-in lock device of described a kind of cabinet drawer is mainly by lower drawer (1), upper drawer (2), cabinet riser (5), cabinet crosspiece (6), dead bolt (3), lockhole, connecting rod (9), rotating shaft (7), spring (8) forms, described lower drawer and described upper drawer all have drawer backboard (4), described dead bolt (3) with described connecting rod (9) by vertical connection of described rotating shaft (7), described rotating shaft (7) is supported on described cabinet crosspiece (6) rotationally, described spring (8) two ends connect respectively described cabinet riser (5) and described connecting rod (9).
As Fig. 3 be as described in drawer backboard front schematic view, described lockhole (10) is positioned at described drawer backboard (4), described lockhole (10) matches with described dead bolt (3).
As in Fig. 1 to Fig. 3, described dead bolt, lockhole, connecting rod, rotating shaft, spring are enlarged drawing, and real in seeing wherein annexation clearly, the space that actual conditions need can be very little.This device arranges one between every two upper and lower drawers, and each device not on a longitudinal straight line, in one group of drawer from top to bottom, only need fill a drawer-lock at a bottom drawer mutually.
