Description
Technical field
The utility model relates to a kind of fire-fighting domain, particularly relates to a kind of emergent window opening device when fire occurs.
Background technology
Along with the raising of people's security against fire consciousness and standard-required, the use of building vent window window opener gets more and more.Traditional window opener comprises driver and telescoping mechanism, and telescoping mechanism is connected by lockset with the bearing be fixed on sash.In normal state, the telescoping mechanism that lockset is connected to window opener and the bearing be positioned on sash, window opener realizes the opening and closing of sash; Under fire or other abnormal conditions, after lockset is opened, emergent window opening device and sash are thrown off, and sash is opened under external force, thus realize emergent windowing function.
There are the following problems under emergency rating for tradition window opener: 1, after sash is opened, after window opener is separated with sash, sash is unrestricted in opening procedure easily to be broken; 2, after sash is opened under emergency rating, when again shutting sash, need to reconnect on the telescoping mechanism of window opener and sash, because window opener is unrestricted, its position easily changes, and again connects and needs to recalibrate and assembling, therefore reconnect process more loaded down with trivial details.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of emergent window opening device, and after sash is opened under emergency conditions, window opener and sash reconnect more convenient.
Solve the technical scheme that technical problem of the present utility model needs to provide: emergent window opening device, the bearing comprising driver, telescopic component and be fixed on sash, driver drives telescopic component is elastic, telescopic component is connected by lockset that is powered or pneumatic control with bearing, described telescopic component is provided with extended or storage often connect guide rod, described telescopic component is connected with described bearing by the described guide rod that often connects.
The further preferred version of the utility model is: described telescopic component comprises screw rod and extension bar, the external screw thread of screw rod and the internal thread of extension bar cooperatively interact, screw rod is provided with axial center hole, often connect guide rod to be located in axial center hole and can to move axially, the front portion of described extension bar is stretched out in the described front end often connecting guide rod.The central hole that screw rod is arranged, in the center of whole device, often connects the pressure ratio that guide rod is subject to and comparatively balances; Often connect guide rod move axially achieve extended or storage function and structure is simple.
The further preferred version of the utility model is: often connect between the rear portion of guide rod and the front portion of extension bar and be provided with position-limit mechanism.Position-limit mechanism is for preventing from coming off from screw rod when stretching out axial center hole when often connecting guide rod at emergency rating.
The further preferred version of the utility model is: described position-limit mechanism comprises the limited block being arranged on and often connecting guide rod rear portion and the spacing hole being arranged on extension bar front portion, and the bore of described spacing hole is less than the width of limited block.Spacing hole and limited block cooperatively interact and prevent often connecting guide rod and come off from screw rod.
The further preferred version of the utility model is: described lockset comprises the dead bolt being arranged on extension bar front end and the lock nut be arranged on bearing, and described spacing hole is positioned at the center of tapered end.Dead bolt and lock nut structure simply, can realize the function unlocking and unblank easily.
The further preferred version of the utility model for: described lock nut be provided with for described in the cavity that enters, the sidepiece of described cavity is provided with telescopic annular protrusion, and described dead bolt is provided with annular groove; Under lockset locking state, dead bolt enters in the cavity of described lock nut, and described annular protrusion snaps in described annular groove, and under lockset released state, dead bolt is separated with described lock nut.Annular protrusion is telescopic, when annular protrusion does not receive extruding, blocks dead bolt; When annular protrusion is squeezed, the internal diameter of annular protrusion becomes large, dead bolt can be made to free in and out, reach the effect freely unlocking and unblank.
Compared with prior art, under advantage emergency rating of the present utility model, lockset is released, telescopic component on window opener and bearing are in free state, sash is opened under servomechanism or self-gravity action, but often connect guide rod to be connected between telescopic component and sash, what often connect that guide rod can limit sash opens amplitude, avoids sash to damage because opening excessively always.In sash opening procedure, often connect guide rod and follow sash and stretch out, keep electric window-opening device to be in original position always, when sash is closed again, can again window opener and sash be coupled together without the need to calibration again.
