Abstract
The utility model discloses a side hung fire resisting door which is composed of a door frame, door leaves, and hinges. The door frame is connected with the door leaves by the hinges; both sides of each door leaf can form a fire surface and an inverse fire surface. The utility model is characterized in that one side of a left door leaf and a right door leaf approaching to a rabbet of the door frame is provided with a stepped notch; at least a moving middle seam and a group of hinges are arranged on the notch of one door leaf; the moving meddle seam is connected with each door leaf by the hinges. The utility model can cancel the rabbet of the pressing and lapping type middle seam and an ordinal device, so that the utility model can enhance the service life of the fire resisting door and can reduce the cost of the fire resisting door.
Description
The utility model relates to a kind of flat open labeled door, especially a kind of flat labeled door of opening with the movable sealing centre joint.
At present, common biparting anti-valve all has centre joint seam, and the common form of centre joint seam adopts left and right sides door leaf pressure overlapped, and the one, fire prevention, the 2nd, prevent to scurry cigarette.But, adopt pressure overlapped centre joint seam, door leaf is damaged, according to investigations, used about 1 year, centre joint seam can be subjected to damage in various degree.In addition, the labeled door of pressure overlapped centre joint seam must install sequencer additional, could guarantee that the order of labeled door is closed door.The use of sequencer can cause the support bar of labeled door direct collision control sequence device, causes the sequencer shearing excessive and cut off or loose or dislocation.Door leaf is subjected to sequencer and flings reaction force, and depression appears in the shop front, causes the door leaf damage.
The purpose of this utility model provides a kind ofly can cancel pressure overlapped centre joint seam, does not have the flat labeled door of opening of sequencer.
The technical solution of the utility model is: the flat labeled door of opening, form by doorframe, door leaf and hinge, doorframe, door leaf are connected by hinge, the both sides of door leaf form and are subjected to fiery face and by fiery face, it is characterized in that left and right sides door leaf is provided with the stairstepping notch in the side near the doorframe seam, and be provided with movable centre joint bar and one group of hingen at least on a door leaf notch, the movable centre joint is connected with door leaf by hingen.Described notch cuttype notch is positioned at door leaf contact surface one side, and runs through whole door leaf and vertical with ground.Described hingen is made up of base, torsion spring and swing angle degree impeller, and base is fixed on the door leaf, and swing angle degree impeller is connected with base by torsion spring.Described movable centre joint bar connects whole door leaf and perpendicular to ground.The width of described movable centre joint bar is less than two door leaf width of rebate sums.Such scheme is applicable to various vertical hinged door classes.
Operating principle of the present utility model is: the flat labeled door of opening of the band movable sealing centre joint, after left and right sides door leaf cuts out, be provided with seam on the door leaf contact doorframe of the movable centre joint, insert in another door leaf stairstepping notch in, play every the effect of cigarette fireproof.Movable centre joint bar is connected by hingen with door leaf, hingen is made up of base, torsion spring and swing angle degree impeller, the hingen base is fixed on the door leaf, swing angle degree impeller is opened certain angle by the active force of torsion spring, fixed thereon movable centre joint bar shaped becomes the movable sealing centre joint, when door leaf is opened, and hidden back of angle of the swing angle degree impeller of hingen rotation at this door leaf, do not collide with other Yishanmen, unaffected mutually.
The utility model has the advantages that: the flat labeled door of opening of the band movable sealing centre joint, left and right sides door leaf is provided with the stairstepping notch in the side near the doorframe seam, and on a door leaf notch, be provided with movable centre joint bar and one group of hingen at least, the movable centre joint is connected with door leaf by hingen, therefore can cancel pressure overlapped centre joint seam and sequencer, thereby improve the application life of labeled door, reduce the cost of labeled door.
Below in conjunction with drawings and Examples the utility model is further described.
Fig. 1 is the flat front view of opening labeled door of the band movable sealing centre joint;
Fig. 2 is Fig. 1 vertical view;
Fig. 3 is the enlarged drawing figure of A portion of Fig. 2.
Among Fig. 1, the flat labeled door of opening of the band movable sealing centre joint, form by doorframe 1, left-hand door fan 2, right door leaf 3 and hinge 4, doorframe 1, left-hand door fan 2, right door leaf 3 are connected by hinge 4, the both sides of left-hand door fan 2 and right door leaf 3 form and are subjected to fiery face and by fiery face, left-hand door fan 2 and right door leaf 3 are provided with stairstepping notch 5 in the side near the doorframe seam, are provided with movable centre joint bar 7 and one group of hingen 6 on the door leaf notch 5, and movable centre joint bar 7 is connected with door leaf by hingen 6.The notch cuttype notch is positioned at door leaf contact surface one side, and runs through whole door leaf and vertical with ground.Hingen 6 is made up of base 8, torsion spring 9 and swing angle degree impeller 10, base 8 is fixed on the door leaf, swing angle degree impeller 10 is connected with base 8 by torsion spring 9, movable centre joint bar 7 connects whole door leafs and perpendicular to ground, movable centre joint bar 7 by the width of a low carbon steel plate manufacturing and its width less than two door leaf notches, 5 width sums.
