Embodiment
The present invention is described in further detail below in conjunction with accompanying drawing embodiment.
Traditional electric chain window opener is all forward and reverse rotation by motor to realize unlatching or the pass to vent window
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 been damaged, the power breakdown under sash closed mode, therefore sash can not pass through chain window-opening machine quilt
Open.The present invention is considered when chain window-opening machine is damaged, and under the chain and sash connection status of chain window-opening machine, how to be led to
Cross servomechanism or manually open sash.
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
Repeated no more in some prior arts, 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 using 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, still can be to lock
Tool 7 is supplied.
As shown in Figure 7 and Figure 8, under abnormal conditions, electric chain window opener can not open sash 2, after lockset 7 is unlocked,
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, due to the opening of sash 2, and 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 is moved, 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, lockset 7 and are provided with locked groove 12, in lockset 7
When locking A2 ends, locked in the insertion locked groove 12 of pivot pin 11 and by the locking bar 14 of lockset 7；After lockset 7 is unlocked, pivot pin 11 is removed
Locked groove 12 so that the A2 ends of shell 4 are in free state.
Servomechanism 5 is gas spring or spring push-rod, the active force that servomechanism 5 is outwardly opened to sash 2 one all the time.
When applied to side window, servomechanism 5 provides that most initial thrust, after sash 2 opens a part, and sash 2 can be according to
Mode by deadweight continues to open.When applied to skylight, servomechanism 5 needs larger strength just can all 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 the outwardly directed length of drive chain 13, 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 present invention is described in detail above, it is used herein specifically individual
Example is set forth to the principle and embodiment of the present invention, and the explanation of above example is only intended to help and manages the present invention and core
Thought is thought.It should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention,
Some improvement and modification can also be carried out to the present invention, these are improved and modification also falls into the protection domain of the claims in the present invention
It is interior.
