Abstract
The release device is characterized in its tube sleeve and drag rod, the drag rod has springs, fusible lock fastener, fastener holder and lock plate, which are restricted on the drag-rod. When the fusible lock fastener has blown out, one of the springs and lock plate separate from the tube sleeve and push the drag rod moving downwards, the upper part of the drag rod is linked to a horizontal drag ring.
Description
The present invention relates to a kind of fire-retardant-plate door that is used for, the particularly releasing device of flat opening fire-retardant-plate door.
Chinese patent communique (1985-1995.4) and Chinese achievement compilation (1978-1994) is not seen by retrieval the identical or similar structure report with the present invention.
Purpose of the present invention just provides a kind of releasing device for fire-retardant-plate door
The objective of the invention is to finish like this: releasing device for fire-retardant-plate door comprises pipe box, pull bar, on pull bar, be provided with spring, meltable pintle hook lock and card sign indicating number and jam plate are limited in spring on the pull bar above the jam plate, after the meltable pintle hook lock fusing, spring and jam plate break away from pipe box and pushing drawing rod moves downward, and the pull bar top is stretched draw ring and linked to each other with flat.
Purpose of the present invention can be finished equally like this: the spring that is provided with on pull bar, the spring diameter of below is bigger than the diameter of top.
Purpose of the present invention can be finished equally like this: the spring that is arranged on the pull bar is a left and right sides double-spiral structure.
Purpose of the present invention can be finished equally like this: be provided with draw ring below pull bar.
Purpose of the present invention can be finished equally like this: meltable pintle hook lock comprises screw cover, hollow screw, and fusible metal links together screw cover, hollow screw.
The present invention has following advantage:
1, rational in infrastructure.Structure of the present invention mainly is made of pipe box, pull bar, meltable pintle hook lock, jam plate, spring, thereby simple and reasonable.
2, easy to use, accurate.During breaking out of fire, meltable pintle hook lock can in time fuse, and in the effect of door spring hinge, promptly closes fire-retardant-plate door, cuts off burning things which may cause a fire disaster.
3, the present invention is a fire-retardant-plate door, and particularly the flat opening fire-retardant-plate door provides a new releasing device.
Fig. 1 is the structure chart of releasing device for fire-retardant-plate door;
Fig. 2 is the another kind of structure chart of releasing device for fire-retardant-plate door;
Fig. 3 is the releasing device for fire-retardant-plate door component diagram;
Fig. 4 is the meltable pintle hook lock structure chart of releasing device for fire-retardant-plate door.
Further be illustrated below in conjunction with drawings and Examples, but be not limited only to following examples.
By accompanying drawing 1,2,3,4 as can be known, releasing device for fire-retardant-plate door comprises pull bar (1) spring (2), (5), fixed mount (3), pipe box (4), card sign indicating number (6), jam plate (7), meltable pintle hook lock (8), draw ring (9), wall (10), meltable release (11), flat draw ring (12), door leaf (13), screw cover (14), hollow screw (15), fusible metal (16), the nut (17) stretched.
The course of work of releasing device for fire-retardant-plate door is: when fire takes place, temperature raise (60-300 ℃ this temperature can according to the selected of fusible metal determined), after meltable pintle hook lock (8) fusing, spring (2) promotes spring (5) and jam plate (7) breaks away from pipe box (4), thereby pushing drawing rod (1) moves downward, pull bar (1) is deviate from the flat draw ring (12) of stretching on the door leaf (13), and door leaf (13) cuts out under the effect of spring hinge automatically, realizes the purpose that fire prevention cuts off.
Under the usual situation, pull bar (1) stretches out (making progress) fixed mount (3), when fire-retardant-plate door is opened about 90 °, the flat draw ring (12) of stretching that is fixed on the door leaf (13) packs into pull bar (1), and this moment, spring hinge can't make door close, when desiring door is shut, hand spurs draw ring (9) downwards, the descending flat ring of deviating from the door leaf (13) (12) of stretching of pull bar (1), door leaf this moment (13) cuts out under the effect of spring hinge, and this device is fixing on the wall by fixed mount (3).
Claims (5)
