Description
Technical field
The present invention relates to protective door more particularly to a kind of keepers from hydrant fire resistant doorsets.
Background technique
Fire resistant doorsets have according to material division: fire-proof wooden door, fire resistance steel door, steel wood fire resistant doorsets, other fire resistant doorsets etc. are existing
When some fire resistant doorsets have the disadvantage that door-plate is closed on all doorframes, only it is fixed by lock, there are fix tightly soundness
Difference generates explosion time in kindling and is easy to be opened by impact；It can not be connected with the water system in fire-fighting system to realize in fire
Calamity is put out a fire when generating.
Summary of the invention
The first purpose of this invention be intended to provide it is a kind of be provided with keeper and close on when the automatic bolt of keeper on be equipped with
The fire resistant doorsets of bolt only pass through lock when solving the closing of existing fire resistant doorsets and asking for existing fixation poor reliability are fixed
Topic.
The second object of the present invention is further intended to provide and a kind of can be attached with the water system in fire-fighting system
Keeper from hydrant fire resistant doorsets, solve the problems, such as that existing fire resistant doorsets can not put out a fire.
The above technical problem is solved through the following technical scheme: a kind of keeper from hydrant fire resistant doorsets, wrapper sheet doorframe and
One end of door-plate, door-plate horizontal direction is hinged with one end of doorframe horizontal direction, the other end of door-plate and doorframe it is another
Door lock is equipped between one end, which is characterized in that the other end of the doorframe is equipped with bolt hole, the end face of the other end of the door-plate
What is be equipped with can be additionally provided with operation with the sideslip hole along the extension of door-plate width direction that the bolt hole is aligned, the door-plate
Door-plate is run through along door-plate thickness direction in hole, the operation hole, and the operation hole is the strip extended along door-plate width direction
