Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing embodiment.
Traditional electric chain window opener is all to realize unlatching or the pass to vent window by forward and reverse rotation of motor
Close, if in the case where having electricity and motor intact, normal work needs can be met；But when fire occurs, electric power may
It can interrupt or motor has damaged, the power breakdown under sash closed mode, therefore sash can not pass through chain window-opening machine quilt
Open.The utility model is considered when chain window-opening machine damages, and under the chain of chain window-opening machine and sash connection status, such as
What opens sash by servomechanism or manually.
As shown in Figure 1 to Figure 3, electric chain window-opening mechanism, including window frame 1, side are hinged on the and of sash 2 on window frame 1
Chain window-opening machine 3, the shell 4, actuating unit and chain 13 that chain window-opening machine 3 includes strip extensively should using in the market
Some prior arts, repeat no more in present embodiment, the extended or retracted shell 4 of actuating unit drive chain 13, chain
13 stretch out from the sidepiece of shell 4 and are connected with sash 2, and the A1 sides of window frame 1 are provided with lockset 7, as is illustrated by figs. 11 and 12, window frame
1 B1 sides be provided with one can the contiguous block 9 with guide groove 8 that rotates of original place, the contiguous block 9 can be connected on a support 10 with axle
On, the support 10 is fixed on the B1 sides of window frame 1.The outside of support 10 to window frame 1 is slightly tilted a little, in order that leading on shell 4
Window frame 1 is avoided to bar 6.Window frame 1 is hinged on window frame 1 perpendicular to ground, the downside of sash 2.
The A2 ends of shell 4 are locked by lockset 7；The B2 ends of shell 4 are fixed with guide rod 6, and guide rod 6 passes through connection
The guide groove 8 of block 9；
As shown in Figures 4 to 6, under normal circumstances, sash 2 is opened or closed by electric chain window opener, electronic
The shell 4 of chain window-opening machine is to maintain motionless, i.e. the A2 ends of shell are locked by lockset 7.Lockset 7 can use electromagnetic lockset or
Pneumatic lockset, electric power or source of the gas herein can use non-firm power or bailout gas, i.e., in abnormal cases, can still give lock
The supply of tool 7.
As shown in Figure 7 and Figure 8, under abnormal conditions, electric chain window opener can not open sash 2, after lockset 7 unlocks,
The A2 ends of shell 4 are in free state；During manual or servomechanism 5 opens sash 2, electric chain window opener passes through
Chain 13 follows sash 2 to rotate, and due to the opening of sash 2, the back-end location of chain window-opening machine changes, therefore shell 4
Guide groove 8 of the guide rod 6 along the contiguous block 9 being rotating on B2 ends moves, while contiguous block 8 can follow guide rod 6 to send out
It is raw to rotate.
As shown in Figure 9 and Figure 10, the A2 ends of shell are fixed with pivot pin 11, and locked groove 12 is provided with lockset 7, in lockset 7
When locking A2 ends, pivot pin 11 is inserted in locked groove 12 and locked by the locking bar 14 of lockset 7；After lockset 7 unlocks, pivot pin 11 removes
Locked groove 12 so that the A2 ends of shell 4 are in free state.
Servomechanism 5 is gas spring or spring push-rod, and servomechanism 5 gives sash 2 one active forces outwardly opened all the time.
When applied to side window, servomechanism 5 provides that thrust of most initial, and after sash 2 opens a part, sash 2 can be according to
Continue to open by the mode of deadweight.When applied to skylight, servomechanism 5 needs larger strength just can all to beat sash
Open.
Actuating unit includes motor and reduction gearing, and motor is connected by reduction gearing with chain 13.Electric chain opens a window
Machine by the rotating of motor come 13 outwardly directed length of drive chain, so as to open or close sash 2.
The section of guide rod 6 is circular or square, and the section of guide groove 8 is adapted with guide rod 6, such as Fig. 8, Figure 11 and figure
Shown in 12.Between guide rod 6 and guide groove 8 by the way of coefficient of friction is less, to reduce friction during both relative movements
Power.
As shown in Figure 7 and Figure 8, the bearing of trend of guide rod 6 is consistent with the length direction of the shell 4 of chain window-opening machine.
As shown in Fig. 2 under the closed mode of sash 2, there is certain angle of inclination between chain window-opening machine and window frame 1.
As shown in Figure 5 and Figure 6, the fixing end of servomechanism 5 is installed on window frame 1, and the front end of servomechanism 5 is connected to window
Fan 2.
Electric chain window-opening mechanism provided by the utility model is described in detail above, tool used herein
Body example is set forth to principle of the present utility model and embodiment, and the explanation of above example is only intended to help and manages this
Utility model and core concept.It should be pointed out that for those skilled in the art, it is new not departing from this practicality
On the premise of type principle, some improvement and modification can also be carried out to the utility model, these are improved and modification also falls into this reality
With in new scope of the claims.
