Outer opening structure includes door handle, spindle, dead bolt fixture, dead bolt, latch hook, interior drives jacking block and lock shaft fixture, latch hook
It is installed on the casing of gate side, dead bolt is installed in dead bolt fixture, and its outside external part is buckled into latch hook, the door
Handle is installed on spindle by two lock shaft fixtures, and latch hook is provided with two, is respectively arranged at lock shaft fixture
Upper and lower side；The interior opening structure includes internally-opened handle, internally-opened handle fixed seat, interior open rotating shaft, interior opens top, push rod and top
Bar guide, push rod outboard end just internally open jacking block.
As preferable technical scheme, the internally-opened handle is installed in internally-opened handle fixed seat, internally-opened handle fixed seat
Rotating shaft is opened in output end connection, inside opens in the setting of rotating shaft output end and opens top, inside open the rotate counterclockwise direction face top of top
Bar, push rod are installed in push rod guide, and push rod guide is fixedly installed in gate medial surface.
As preferable technical scheme, dead bolt fixture and lock shaft fixture are fixed on gate side, and latch hook is fixed on
On the casing of gate side, sealing ring is installed in internally-opened handle fixed seat.
As preferable technical scheme, top and push rod guide are inside driven using the higher heat-barrier material of intensity.
The beneficial effects of the utility model are：The utility model door lock Internal handle seals heat-insulated, air tight, water-tight, energy
Suitable for most chambers, and there is the interior experiment box door lock for opening function.
Brief description of the drawings
, below will be to embodiment in order to illustrate more clearly of the utility model embodiment or technical scheme of the prior art
Or the required accompanying drawing used is briefly described in description of the prior art, it should be apparent that, drawings in the following description are only
