Abstract

The utility model relates to an electromagnetic releasing door closer, be used for preventing fire door, it discloses the single gear wheel, positioner, stir the connecting rod, transmission connecting rod, detain the pole, the extension spring is in flakes in the box outside, the connecting rod, single gear takes turns coaxial arrangement, be fixed with positioner by the single gear wheel, be provided with the slot on the fixing base on positioner next door, transmission linkage installs in the slot, and can the back -and -forth movement, be provided with the breach on the slot, with be provided with the bayonet socket on the corresponding transmission linkage in the breach position of slot, the one end of detaining the pole hinges the telescopic rod hinge who lies in breach next door, the other end and relay on the slot, the one end of stirring the connecting rod articulates the front end at transmission linkage, and the other end articulates on positioner's driving lever. The utility model has the advantages that the door closer designed that to prevent that fire door opens the angle more nimble than traditional for it, can stop in the arbitrary angle of 0 -180 degree, and reset action is swift more, sensitive, reliable, and life is longer in addition, and it is more convenient to install.

Description

Electromagnetic releasing door closer
Technical field
This is with the novel electromagnetic releasing door closer that relates to, and specifically a kind of opening angle is flexible, the electric-controlled type fireproof door closer that homing action is quick, sensitive.
Background technology
Door closer is wide variety of accessory on fire resistant doorsets socially, electromagnetic releasing door closer has a variety of with fire resistant doorsets Aided design in fire generation triggering design, the most active, passive type, active, passive type etc., and present fire-fighting link door closer majority makes fire resistant doorsets open angle fix, in actual life, the size of fire resistant doorsets open angle also has different demands according to different environmental, and traditional fire prevention is closed couplet on the door clutch open angle and controls underaction, quick, sensitive, when applying some environment, inconvenience is installed.
Utility model content
The purpose of this utility model is to provide electromagnetic releasing door closer, it is more more flexible than the fire resistant doorsets opening angle designed by traditional door closer, can be in the arbitrarily angled stop of 0-180 degree, and homing action is more quick, sensitive, reliable, and service life is longer, easier for installation.
Technical solution of the present utility model is box outside, lid, connecting rod, extension spring, relay, back-moving spring, extension spring is in flakes, feedback switch, on the basis of fixing seat, it is characterized in ratchet, positioner, stir connecting rod, kinematic link, button bar, in box, extension spring is fixed with ratchet with in the same rotating shaft of connecting rod in flakes outside, it is fixed with positioner on ratchet side, it is provided with slot on the fixing seat on positioner side, kinematic link is arranged in slot, and can move forward and backward, interlude at slot is provided with breach, it is provided with bayonet socket on the kinematic link corresponding with the gap position of slot;One end of button bar is hinged on slot and is positioned at breach side, and the other end is hinged with the expansion link of relay;The one end stirring connecting rod is hinged on the front end of kinematic link by bar hole, and the other end is hinged on the driving lever of positioner.
Above-described positioner is by fixing seat, driving lever, locating detent, spring, positive stop bead forms, and described driving lever and locating detent are co-axially mounted on fixing seat, the shank of driving lever protrudes into outside from the driving lever hole of lid, the section back, the end of driving lever is provided with restriction pit, and position corresponding with limiting pit on fixing seat is provided with the installing hole of positive stop bead, and positive stop bead is arranged on this hole;Between section back, top and the driving lever of locating detent, be provided with spring, locating detent can under the drive of driving lever with the teeth clamping of ratchet or unclamp.
Operation principle of the present utility model is to be locked the opening angle of fire resistant doorsets by the locating detent of positioner, need when seated to test the action of fire resistant doorsets whether normal time, the driving lever that only need to stir positioner makes locating detent leave ratchet, extension spring just can trigger fire resistant doorsets and close the door action, it is connected with kinematic link by bar hole because stirring connecting rod, so signal feedback will not be produced tactile feedback switch, thus be that the purely mechanic performance installation test completing fire resistant doorsets brings conveniently, when electronic test, relay drives button bar to unclamp bayonet socket, spring reset drive kinematic link interlocks with stirring connecting rod, the locating detent making positioner leaves ratchet, the action of closing the door of extension spring reset trigger fire resistant doorsets completes automatically controlled action.
The utility model has the advantages that it is more more flexible than the fire resistant doorsets opening angle designed by traditional door closer, can be in the arbitrarily angled stop of 0-180 degree, homing action is more quick, sensitive, reliable, and service life is longer, easier for installation.
