Description
Technical field
The invention belongs to telescopic door and window closers and door that building doors and windows technical field more particularly to an a kind of key are closed
Window.
Background technology
Door and window closer is both provided on existing fire-proof doors and windows, these door and window closers are in rear temperature rise on fire to 74
It needs that sash or door leaf are automatically closed in 1 minute at DEG C ± 0.5 DEG C.Sash and being automatically closed for door leaf need door and window to be closed
Device, fire prevention temperature control supporting rod could meet closedown condition using warming closer auxiliary, door and window closer currently on the market,
Preventing fires, temperature control supporting rod, warming closer are expensive, installation is complicated, appearance is poor.
In addition, door and window closer currently on the market does not have the function of key closure, only just when fire occurs
It can trigger and be automatically closed, in the case where largely working normally, close window and people is needed to be manually retracted by body part stretching outside window
Sash is closed and is locked, inconvenient, and for the inadequate children of brachium, the action for closing window is extremely dangerous, exist from
The security risk that window falls.Hand, which is stretched out pass window, under the conditions of atrocious weather simultaneously can cause to be soaked with rain, user's body
Test difference.
Invention content
The technical problem to be solved in the present invention is to overcome the shortcomings of the prior art, provides a kind of simple in structure, cost
Cheap, easy for installation, exquisite appearance is provided simultaneously with the telescopic door and window closer and door and window of a key closure function.
In order to solve the above technical problems, technical solution proposed by the present invention is：
The telescopic door and window closer that an a kind of key is closed, include frame-connecting member for being connect with framework and for
Fan body connection fan body connector, be slidably connected between the frame-connecting member and fan body connector, the frame-connecting member with
Sliding stroke between fan body connector can be conditioned by telescopic slide, and the door and window closer further includes for locking limit
Make the lock piece of telescopic slide movement between the frame-connecting member and the fan body connector, for releasing the lock piece
The unlock piece of restriction effect and for drive fan body close self-closing actuator, the lock piece be set to the frame-connecting member or
On fan body connector, the unlock piece is connect with the lock piece, and the self-closing actuator is set on framework or fan body or framework
Between fan body.Between fan body connector and frame-connecting member can telescopic slide adjust sliding stroke, therefore can be by changing
The length for becoming fan body connector and the straight line of frame-connecting member composition to adjust the aperture of fan body unlatching indirectly, and passes through locking
The function that a key is closed is realized in the common mating reaction of part, unlock piece and self-closing actuator.
The telescopic door and window closer that an above-mentioned key is closed, it is preferred that the door and window closer further includes in fire
The temperature controller that the restriction effect of the lock piece makes fan body close can be released, the temperature controller includes pushing block, for providing promotion
The spring of power and the temperature control pearl that pushing block is limited in normal use and releasing can be crushed in fire to the position-limiting action of pushing block.
Temperature controller has made door and window closure device that the function of door and window be automatically closed for fire prevention, and in the case of fire, temperature controller can be rapid
Response drives unlock piece to close the doors and windows, inhibits the sprawling of the intensity of a fire, more in time.
