Abstract
A steel composite fireproof rolling shutter hinge for an evacuation door is a key part for arranging an evacuation small door on a large-scale steel composite fireproof rolling shutter, and is characterized in that the joint parts of two hinges and a curtain plate hook are in a circular arc structure, and are combined by a convex-concave semi-circular arc surface, so that the hinge can be used for vertical opening and the rotation of the curtain plate is not influenced after connection.
Description
One, technical field
The application relates to the structure of fire prevention volume egress door hinge, particularly both can equal out usefulness, can rotate with every page of curtain plate again after being connected.
Two, background technology
The hinge of common labeled door is used on the fire curtain curtain plate, can only equal out usefulness after the installation, can not rotate with curling of curtain plate, at this problem, need a kind of hinge structure of development, can on the curtain plate of fire curtain, make the usefulness of vertical hinged door, can rotate and resilience automatically the hole of not boxing out with curling of curtain plate again.
Three, summary of the invention
At the problems referred to above, a kind of being applied to of special proposition both can be equalled out usefulness on the steel composite fireproof roller shutter curtain plate, again can be with the curling novel hinge that rotates of curtain plate.Technical scheme is:
Steel composite fireproof roller shutter egress door hinge is characterized in that two hinge binding sites and curtain plate hook etc. are arc structure, and adopts the combination of convex-concave semicircle cambered surface.
Adopt this technical scheme can solve the purposes of offering egress door on the fire curtain.
Four, description of drawings
Accompanying drawing 1 is the structural representation of steel composite fireproof roller shutter egress door hinge.
Five, the specific embodiment
The structure of compound curtain plate, adopt accurate steel-casting mould, smart casting material adopts the 45# steel, two hinge binding sites and curtain plate hook etc. are arc structure, and employing convex-concave semicircle cambered surface combination, machining is carried out by technical requirements in the casting back, assembles, and can use on corresponding fire curtain.
Above embodiment writes in order to make the present invention narrate clear, and not exclusive embodiment, and all embodiment within the claimed scope of claims are the claimed scope of the present invention.
