Abstract
The utility model discloses a temperature-control fusing and releasing device for a rolling door, which is suitable for a fireproof rolling door rolled perpendicular to the ground. A movable slide block is arranged in a box body of the utility model, a tension spring is respectively connected with the slide block and the box body, a pulling rope is respectively connected with the slide block and a clutch of an opening or closing machine of the rolling door, and two pin shafts respectively pass through the slide block and the box body; metal sheets welded by fusible alloy are arranged on both ends of each pin shaft. When surrounding temperature exceeds a definite value, the fusible alloy melts, the metal sheets separate, the clutch is disengaged by the pulling rope under the action of spring force, and the rolling door is automatically released dropping down. The utility model has the advantages of agile movements, reliable movements, simple structure, easy installation, and easy regulation. The utility model can match with opening or closing machines of domestic rolling doors.
Description
A kind of rolling door temperature control fusing releasing device is applicable to the fire resistance rolling shutter door that the vertical ground volume is put, and belongs to building fire protection equipment field.
In the modern architecture industry, in order to reach the requirement of fire code, labeled door is used widely, and wherein fire resistance rolling shutter door is wide with its applicability, has become one of building ' s fire system important composition part.When breaking out of fire, volume is put in the curtain plate that pushes up on the door opening should move decline, and door opening is sealed, just can play the effect that fire prevention cuts off, driving power that the curtain plate action descends usually can have electric power and manually, wherein electronic can with the cigarette sense, temperature sense probe connects, and realizes control automatically.
The overseas market temperature control fusing releasing device that occurred again making in recent years with low-melting-point metal, make under the unmanned situation of outage, after interior temperature surpassed a certain critical point, fire resistance rolling shutter door can descend by self-dependent gravity automatically, close the door opening passage, realize the back-fire relief function.
There is complex structure in existing temperature control fusing releasing device, and the supporting binding of electric opening and closing machine that can not use with homemade rolling door.
The purpose of this utility model provides a kind of simple in structure, and can be connected with the electric opening and closing machine that homemade general rolling door is used, the matching used temperature control releasing device that fuses.
Used technical scheme is that this device is designed to a strip case construction, is equipped with one in the casing and is connected in the slide block that can move of wall box long rabbet by bearing pin in casing, and one of extension spring end is connected in this slide block, and end is connected in cabinet base in addition; One stay cord, one end is connected in this slide block, end is connected in the clutch of the switching machine of rolling door in addition, described extension spring axle center, stay cord center and slide block glide direction are in same parallel direction, the front end side wall of described casing is installed with another bearing pin, and is adjacent with the bearing pin that passes slide block, and the two ends of this two bearing pin are connected with two groups of sheet metals respectively, these two groups of sheet metals weld with Lipowitz's alloy, and described fusible metal sheet is designed to action when environment temperature surpasses certain definite value (for example 72 ℃).
The utility model is used through site trial, and it is reliable to be active in one's movements, and structure is simple relatively, and Installation and Debugging have easily realized opening and closing the matching used phase purpose of giving of machine with homemade rolling door.
Now be described further in conjunction with the accompanying drawings with most preferred embodiment.
Fig. 1 is that the utility model is installed the placement schematic diagram.
Fig. 2 is its structure complete section elevation
Fig. 3 is the vertical view of Fig. 2
Fig. 4 is the complete section elevation of casing
Rolling door temperature control fusing releasing device is mainly by casing (1), slide block (2), extension spring (3), stay cord (4), the sheet metal of fusible alloy welding (5), (6) composition is seen Fig. 2 Fig. 3, casing (1) is hollow flute profile, slotted hole (7) and hole, garden (8) are arranged on its sidewall, two holes are close to mutually, and on same axis, slide block (2) passes slotted hole (7) on the wall box by bearing pin (9) and is contained in the casing (1) and can slides in casing (1), and extension spring (3) one ends are connected in slide block (2), and the other end is connected in the base (10) of casing (1); Stay cord (4) one ends are connected in slide block (2), end passes casing (1) and links to each other with the clutch of rolling door switching machine (12) in addition, the axial line of described extension spring (3), the glide direction of the center line of stay cord (4) and slide block (2) should be in same parallel direction, bearing pin (11) is housed in the circular hole on the sidewall of casing (1) (8), described bearing pin (11) also can use double-screw bolt, but the hole (8) that match this moment with it should be screw.At the two ends of bearing pin (9) and (11) two pairs of sheet metals (5) and (6) are housed respectively, each is to welding with fusible alloy (13) between sheet metal (5) and (6).
According to China's fire-fighting fire-proof requirement, the fusible alloy fusing point is decided to be certain certain value (for example 72 ° of degree), temperature control fusing releasing device with this creation during use is installed on indoor near near the switching machine (12) of rolling door (15), be in sustained height (for example ceiling furred ceiling (16) lower edge is seen Fig. 1) with cigarette, temperature sense probe, make stay cord (4) tighten but do not stress.And make spring (3) be subjected to pulling force, after environment temperature surpassed design definite value (as 72 ° of degree), the connection between sheet metal (5) and (6) separated because of fusible alloy (13) fusing.The extension spring (3) of being given the power of straining at is drawn slide block (2) and is drawn stay cord (4) simultaneously and move for replying natural length, and (14) are for being surrounded by the soft rope of stay cord (4) among Fig. 1).Thereby the clutch that rolling door is opened and closed machine (12) is opened, and rolling door (15) descends under the deadweight effect automatically, and door opening is sealed.Realize the back-fire relief function of design for fire protection.
