Specific embodiment
In order that the objects, technical solutions and advantages of the present invention become more apparent, it is below in conjunction with drawings and Examples, right The present invention is further elaborated.It should be appreciated that specific embodiment described herein is only to explain the present invention, and It is not used in the restriction present invention.
As shown in figure 1, a kind of fire resistant doorsets door closer-holder of the present embodiment, installing plate 40 and closing on installing plate 40 Door device 10 and position local device.Wherein door closer 10 is conventional with the door closer for being automatically switched off door leaf function, this enforcement Theing improvement is that for example, on the basis of this kind of conventional door closer, increases position local device.
Position local device in the present embodiment is included as Figure 1-4, including gear 30, gag lever post 31 and lockable mechanism 20.Its middle gear is fixedly connected on the output shaft of door closer 10, and the front end of gag lever post 31 is provided with for being engaged with gear 30 Limiting tooth 32, is additionally provided with stored energy mechanism 35 and slide block 28 on gag lever post 31.Near 31 front end of gag lever post on installing plate 40 Position is provided with bracing frame 1, and the bracing frame 1 is provided with the pilot hole for accommodating that gag lever post 31 passes through.As corresponding support Structure, the position near slide block between bracing frame 1 and slide block 28 are provided with bracing frame 2 34, same on the bracing frame 2 34 It is provided with the pilot hole for accommodating that gag lever post 31 passes through.
Preferably, the gag lever post 31 in the present embodiment is included the first bar 313 for being provided with limiting tooth 32 and is connected with slide block The second bar 311, connected by connector 312 between wherein the first bar 313 and the second bar 311, and be provided with connector 312 Adjust elongated hole 314, the i.e. total length of gag lever post 31 to be adjusted.Install fire resistant doorsets during, be more convenient for install and Adjust the position of door closer-holder.
Stored energy mechanism 35 in the present embodiment is to be sheathed on the gag lever post 31 between bracing frame 1 and connector 312 Spring.In the case where gear shown in Fig. 4 and limiting tooth are engaged, spring is in compressive state, stores elastic potential energy.In locking machine After structure 20 releases the locking to slide block 28, under the resilience force effect of spring, gag lever post 31 is moved to gear shown in Fig. 3 and limiting tooth Detached state.
As shown in Fig. 2 the lockable mechanism 20 of the present embodiment includes pedestal 21 and electric magnet 24, the electric magnet 24 includes electromagnetism Skeleton and the solenoid being wound on electromagnetism skeleton, in the case that solenoid is powered, electric magnet produces magnetic field.In frame The chute 27 matched with slide block 28 is provided between side and electric magnet, and electric magnet 24 is provided with the extension side with chute 27 To gathering sill that is vertical and communicating with chute 27.It should be noted that passing through regulating bolt 29 between frame 21 and electric magnet 24 Connection, the width of chute 27 can be adjusted.
In the present embodiment, electric magnet 24 away from chute 27 side and frame 21 between be provided with latch bolt suction disc 22, this is oblique Connected by elastic component 25 between tongue suction disc 22 and frame 21, preferably, elastic component 25 is spring.It is solid on latch bolt suction disc 22 Surely latch bolt 23 is connected with, the latch bolt 23 is located in the gathering sill of electric magnet.Preferably, by adjusting between latch bolt and latch bolt suction disc Section screw 26 connects, i.e., latch bolt is in the position in gathering sill and stretches into the length in chute 27 and can be adjusted.
In the present embodiment, the end of the second bar 311 is connected with slider bracket 36, and wherein slide block 28 is fixed on the slide block On frame 36.Button mechanism is connected with slider bracket 36 away from one end of gag lever post 31.The button mechanism includes and slider bracket 36 push rods 38 being flexibly connected, be provided with and push rod 38 accommodated by the pusher bar support 37 in hole, located at the button of push rod free end end 381 and the elastic return mechanism 39 between button 381 and pusher bar support 37, wherein slider bracket 36 is provided with connecting hole 361, the front end of push rod 38 is provided with the connection end 384 being adapted with connecting hole 364, and wherein the aperture of connecting hole 361 is more than connection The diameter and the diameter less than push rod 38 at end 384.Further, screw thread 382 is provided with push rod 38 near a section of button 381, Be connected with adjusting nut 383 on thread segment, wherein elastic return mechanism 39 for be sheathed on adjusting nut 383 and pusher bar support 37 it Between push rod 38 on spring.Adjusting nut is used for the energy storage size of regulation elasticity recovery mechanism 39.
Fig. 5 show use state schematic diagram of the present embodiment fire resistant doorsets door closer-holder in fire resistant doorsets, wherein comprising closing The output shaft of the door closer-holder 1 of door device and position local device is connected with principal arm 1, and the free end of principal arm 1 is hinged with auxiliary 3, secondary The other end of arm 3 is hinged with coasting mechanism 4, and wherein in coasting mechanism and door closer-holder, one is installed on doorframe, another peace Loaded on door leaf.
The operation principle of the fire resistant doorsets door closer-holder of the present embodiment is as follows:
In the case where electric magnet is not powered on, in the presence of elastic component 25, latch bolt does not interfere with slide block in chute to latch bolt suction disc In it is current, now, the limiting tooth of gag lever post is separated with gear, and door closer is in running order, and door leaf is being opened and closed Arbitrarily can promote between state.When needing to be fixed on door leaf a certain state of opening(The state is not limited to can be with The maximum magnitude of opening, should be comprising any state between closing and opening), first by pressing to button, promote spacing Bar is moved axially, until limiting tooth is engaged with gear, now slide block is located at the diagram high order end of chute.Nibble with gear in limiting tooth After conjunction, electric magnet is powered, and produces magnetic field, latch bolt suction disc is firmly held, the front end of latch bolt by extending out in gathering sill in chute, By the position limitation of slide block in the left end of chute, anti-limited slip block movement.
In the situation for running into emergency power-off or artificial power-off, electric magnet power-off, electromagnetic force is lost, latch bolt is in elasticity By exiting in chute under the resilience force effect of part, the restriction to slide block is relieved.Now, the elastic potential energy of the storage of stored energy mechanism 35 Release, drives gag lever post to move right, until limiting tooth is disengaged from gear.Now, position local device is relieved to closing The restriction of door device output shaft, door leaf recover to the state that freely can be promoted.
It should be noted that in above-mentioned door closer-holder, the door closer that door closer is used by conventional normally closed fire resistant doorsets has The function of automatic door-closing door leaf.The effect of position local device is, under "on" position, door leaf can be fixed on open mode Unspecified angle position.The door closer-holder is applied in normally closed fire resistant doorsets, you can door leaf is fixed on opening a certain at any time State, to solve to affect ventilation and lighting, block the shortcoming of sight line, inconvenience of passing through, after system cut-off, the locking of position local device Disabler, door leaf are automatically switched off in the presence of door closer, to realize the function of fire resistant doorsets itself.Said structure closes dress The characteristics of putting with simple structure, safe ready.
In a word, presently preferred embodiments of the present invention is the foregoing is only, it is not to limit the present invention, all in the present invention Spirit and principle within any modification, equivalent and the improvement made etc., should be included in protection scope of the present invention it It is interior.
