Include base 2 28 by disconnected switch module 6, base 2 28 is provided with by disconnecting pass 29.
Being provided with pusher bar support 30 on electromagnet casing 8, push rod 16 is arranged on pusher bar support 30.
Pusher button 31 is installed on push rod 16.
Main circuit board 7 is arranged on electromagnet casing 8 by bolt 1.
Base 1 is arranged on electromagnet casing 8 by bolt 2 33.
Base 2 28 is arranged on electromagnet casing 8 by bolt 3 34.
There is in door closer main body 1 base plate and case, electromagnet assembly 3 and rack and pinion assembly 5 be arranged on base plate, mainAlso having microswitch on wiring board 7, main circuit board 7 is connected in circuit, the wiring board 22 of warming assembly 4, by disconnecting pass 29Also being connected in circuit, also electromagnet assembly 3 is also connected in circuit, and oblique block 11 is positioned at electric magnet skeleton 9, it is possible to contractingEntering electric magnet skeleton 9 and also be able to extend electric magnet skeleton 9, the one side that oblique block 11 tilts is positioned at front side, the engagement of gear 23Backlash refers to the gap between adjacent two engaging tooths of gear 23, so that gear 23 in the head end of tooth bar 24 embeds this gapCannot rotate, gear 23 is rotated by rotating shaft 27, and rotating shaft 27 is driven by motor-driven rotation or hydraulic system and rotates, rocking arm2 one end are arranged in door closer main body 1, and the other end is arranged on wall.
During use, power on circuitry, electromagnet assembly 3 is energized, and coil 13 produces magnetic field and inhales sucker 10 at electric magnet skeleton 9On, oblique block 11 is ejected after being held by sucker 10, and oblique block 11 stretches out in electric magnet skeleton 9, and then push rod 16 promotes slidingBlock support 15 moves inward, and slider bracket 15 moves inward band movable slider 14 and moves inward, due to the head end cross section of oblique block 11Inclined setting, and the one side that tiltedly block 11 tilts is positioned at front side, at spring two 11-1 after slide block 14 moves inwardEffect under oblique block 11 is pushed in electric magnet skeleton 9, when slide block 14 enters oblique block 11 rear end, oblique block 11 is at springEjecting under the effect of two 11-1, slide block 14 is blocked by the rear end of oblique block 11, makes slide block 14 position, in slide block 14 position fixing process,Slider bracket 15 promotes tooth bar 24 to embed in gear 23 engaging tooth gap, and now, spring 3 26 is compressed, and embeds tooth at tooth bar 24After taking turns 23 engaging tooth gaps, gear 23 stops operating, and rotating shaft 27 stops operating, and makes rocking arm 2 to rotate, so that door rests onIn the angle set, when, after down circuitry, electromagnet assembly 3 magnetic field disappears, sucker 10 resilience under the effect of spring 1, fromOpening electric magnet skeleton 9, oblique block 11 is under the effect of sucker 10 in retraction electric magnet skeleton 9, after oblique block 11 leaves, and slide block14 infinite places, then spring 3 26 promotes slider bracket 15 to move forward, and slider bracket 15 band carry-over bar 24 leaves gear 23, toothWheel 23 is rotated further, and rotating shaft 27 is rotated further, and makes rocking arm 2 be rotated further so that door is automatically switched off.
So can rest in the angle of needs by door, when evacuating, fire ensure that door rests on needs after occurringAngle, when evacuating, door can rest on the angle of needs, and can be automatically switched off evacuating back door, it is ensured that evacuation smoothLogical, it is to avoid casualties and property loss, the ventilation of building can also be kept under without fire condition.
The temperature of the warming glass bead 18 in warming assembly 4 is 68 DEG C, when fire occurs, and the temperature in warming assembly 4After the temperature of sense glass bead 18 is more than 68 DEG C, warming glass bead 18 bursts automatically, and after warming glass bead 18 explosion, torsion spring 20 drivesReseting plate 19 pushes down microswitch 21, microswitch 21 and wiring board 22 control circuit power-off, and down circuitry makes door closer controlDoor is automatically switched off.
So can carry out automatic door-closing by temperature control assembly, fire automatic door-closing be detected when fire occurs, keep awayExempt from spreading of fire.
Can manually carry out power-off control by closing 29 by disconnection, make door closer be automatically switched off.So can manually carry outPower-off controls, and enables door closer to be automatically switched off.
Can carry out in several ways closing door the most upon occurrence of an emergency situation such that it is able to reply emergency.
The feature of this utility model embodiment is: can rest in the angle of needs by door, and fire is being evacuated after occurringTime ensure that door rests on the angle of needs, when evacuating, door can rest on the angle of needs, and can evacuating back doorIt is automatically switched off, it is ensured that evacuation unimpeded, it is to avoid casualties and property loss, can also keep building under without fire conditionThe ventilation of thing, and automatic door-closing can be carried out by temperature control assembly, fire automatic door-closing detected when fire occurs, keep awayExempt from spreading of fire, additionally it is possible to by manually closing door by disconnected switch module, upon occurrence of an emergency situation can be by multipleMode carries out closing door such that it is able to reply emergency, and practical application effect is good, is beneficial to promote.
