Summary of the invention
The utility model is unlikely to deform to solve the above problems, providing one kind, and its fire-proof function is not influenced by deformation
Fire resistant doorsets.
Technical solution adopted in the utility model:
A kind of distortion-free fire resistant doorsets, including doorframe and three pieces of door-plates, three pieces of door-plates are divided into top door-plate, middle part shutter plate
And lower gate plate, the side on doorframe close to the left side are provided with the wide doorway of door-plate, on doorframe above the top right apex angle on doorway and
Fixing axle is set below bottom, right base angle, is arranged with axle sleeve in fixing axle, one apex angle of axle sleeve and top door-plate of top is fixed
Connection, the axle sleeve of lower section are fixedly connected with a base angle of lower gate plate, the lateral surface interposition of top door-plate and lower gate plate
It installs and is equipped with headed pin, the company of being rotatably connected between the headed pin on headed pin and lower gate plate on the door-plate of top
Bar, the middle part of connecting rod among the lateral surface of shaft and middle part shutter plate by connecting, the medial surface middle position of middle part shutter plate
Slide plate item is set, is provided with sliding slot corresponding with slide plate item on the right side of doorframe.
The both ends of the connecting rod have kidney slot, the kidney-shaped of headed pin insertion connecting rod one end on the door-plate of top
In hole, in the kidney slot of the headed pin insertion connecting rod other end in lower gate plate.
The diameter that the width of the kidney slot is greater than the pin shank of headed pin is less than the diameter of lug cap.
Fin is being arranged close to medial surface in the bottom and upper segment of the middle part shutter plate, and the medial surface of middle part shutter plate is also
It is provided with handle.
The door-plate is made of external metallization frame and the inorganic fire core material plate being filled in external metallization frame.
The utility model has the beneficial effects that door-plate is divided into three parts by the utility model, small area door-plate is unlikely to deform,
And be not under compression and be unlikely to deform when door-plate closure doorway, and heated become larger of door-plate nor affects on the unlatching of three pieces of door-plates, thus
It influences to use.
