Abstract

A fire-proof smoke-isolation sheath for a bolt lock is a sheath for the bolt lock, which is made of thermal expansion pieces, wherein, the fire-proof smoke-isolation sheath comprises a flat rectangular open box and mounting fixing square holes; opposite round rotating shaft holes for the bolt lock are formed on the two large surfaces of the flat rectangular open box; and outwards turning short rectangular pieces are arranged on short edges of a front opening of the flat rectangular open box. The fire-proof smoke-isolation sheath has the benefits as follows: the fire-proof smoke-isolation sheath for the bolt lock is made of the thermal expansion pieces, the sheath for the lock can wrap the bolt lock completely after being installed, and the fire-proof smoke-isolation sheath can expand when fire temperature rises so as to fill up gaps and holes formed on a lock box and a lock head, a rotation rod, a mounting screw as well as other parts of the lock and gaps between the fire-proof smoke-isolation sheath and a fireproof door, so that smoke and heat inflow can be isolated. The fire-proof smoke-isolation sheath achieves the purposes of fire prevention, heat insulation and smoke prevention, prevents people that are not escaped from a room from being poisoned and devitalized, reduces the heated temperature of the lock, and ensures that the lock can be opened normally when fire breaks out.

Description

Fire-proof smoke insulation keeper lock sheath

Technical field

The utility model belongs to the labeled door parts, particularly a kind of fire-proof smoke insulation keeper lock sheath.

Background technology

The fire of building can produce a large amount of poison gas, is the threat of a danger close to the people in the room that in the building, do not catch fire.If can finely avoid poison gas to bolt into the room from the door slit of corridor, be that the personnel that have little time to escape from that prevent not catch fire in the building in the room avoid because of the fatal key of poison gas.

Except that crack between a door and its frame, also have the slit of keeper lock, also can scurry cigarette.

The utility model content

The utility model technical problem to be solved is: a kind of fire-proof smoke insulation keeper lock sheath is provided.Cigarette is scurried in the slit that prevents the keeper lock.

The technical scheme of the utility model is:

A kind of fire-proof smoke insulation keeper lock sheath; It is characterized in that: a keeper lock sheath of processing by the thermal expansion sheet; It is a flat rectangular aperture box; The rotating shaft circular hole of relative keeper lock is arranged on two big faces of flat rectangular aperture box and install and fix square hole, the oriented rectangle short-movie that turns up in the minor face place of open front place of flat rectangular aperture box.

The utility model effect is:

This fire-proof smoke insulation keeper lock sheath is processed by the thermal expansion sheet; When the building corridor catches fire; The temperature of its fire fire can be baked the thermal expansion sheet and risen; The slit of closing door bolt-lock and door effectively stops in toxic smoke gas bolts into the room from the slit of the door keeper of corridor lock and door, prevents that the personnel of not fleeing from poison fatal in the room.

, inflatable when fire temperature raises after this sheath is installed fully with keeper lockset parcel, fill the space between each interporal lacuna on tapered end, swing arm, installation screw rod and other part and the lock box of lockset and it and the labeled door, the inflow that completely cuts off smog and heat.Reach the purpose of fire prevention, heat insulation, resistance cigarette, it is fatal to prevent in the room that the personnel of not fleeing from poison, and has reduced the heating temperature of lockset, guarantees when fire takes place, can normally open.

The specific embodiment

A kind of fire-proof smoke insulation keeper lock sheath as shown in the figure; A keeper lock sheath of processing by the thermal expansion sheet; It is a flat rectangular aperture box 1; Rotating shaft circle 2 holes of relative keeper lock are arranged on two big faces of flat rectangular aperture box and install and fix square hole 3, the oriented rectangle short-movie 5 that turns up in two minor face places of open front place 4 of flat rectangular aperture box.

When the building corridor catches fire, the temperature of its fire fire can rise the thermal expansion sheet is roasting, and the slit of closing door bolt-lock and door effectively stops in toxic smoke gas bolts into the room from the slit of the door keeper lock of corridor and door, prevents that the personnel of not fleeing from poison fatal in the room.

Claims

1. a fire-proof smoke insulation keeper is locked sheath; It is characterized in that: a keeper lock sheath of processing by the thermal expansion sheet; It is a flat rectangular aperture box; The rotating shaft circular hole of relative keeper lock is arranged on two big faces of flat rectangular aperture box and install and fix square hole, the oriented rectangle short-movie that turns up in two minor face places of open front place of flat rectangular aperture box.
