Description
Technical field
This utility model relates to a kind of door closer, particularly a kind of fire resistant doorsets door closer.
Background technology
At present, existing door closer is all the normally off door closer, is mostly installed on the fire resistant doorsets of closedown throughout the year, keeps at any time
Fire resistant doorsets are closed, and when preventing fire from occurring, big fire is spread by fire resistant doorsets, and this door closer is in artificial abortion's throughput not
On big fire resistant doorsets practical；But, in the public building that artificial abortion or logistics are bigger, this door closer often cannot reach
To real requirement, owing to artificial abortion or logistics need to travel frequently over fire resistant doorsets, people need plenty of time and muscle power to open fire resistant doorsets,
The facility that strong influence people walk, if being fixed on opening with instrument by fire resistant doorsets, due to anti-when fire occurs
Vent is in opening, it is impossible to close in time, and fire will pass quickly through fire resistant doorsets and spreads to surrounding, life and the property to people
Very harmful.
Door closer, is that one is electrified for a long time by electromagnet also known as linkage door closer, produces strong magnetic and firmly press tongue
On sucker, thus the position of fixing pressure tongue, pressure tongue limits slide block and moves back, and slide rail props up with door closer and connects arm and be connected.Thus
Reaching the angle that fire resistant doorsets are spacing, when electromagnet power-off, magnetic force disappears, and slide block, under the effect of fireproof door closer, has
The moment closed the door, backs down pressure tongue, releases the spacing of fire resistant doorsets, closes fire-proof door leaf.Existing door closer needs long-term logical
Electricity, its use cost is high.(spacing, guide elements, use POM material, meet high-temperature and easily decompose, deformation, there is safety greatly hidden
Suffer from.)
Or a kind of product, electromagnetism closes a release.It is internal is electromagnetic valve and brute spring (or fireproof door closer),
Compression spring by snap close locking when pushing, makes door maintain a normally open normal state, the bounce-back of electromagnetic valve release pre-compressed spring when obtaining electric
Impulsive force opens locker, closes door leaf under brute spring (or fireproof door closer) acts on.Owing to fire resistant doorsets are closed door
Device body is built in inside electromagnetic releaser, adds lockable mechanism and electromagnetic valve, so the volume of product is relatively big, and general fire resistant doorsets
Frame cannot be installed.Spring or door closer built-in closedown dynamics cannot adjust.
