Specific implementation mode
Below in conjunction with attached drawing embodiment, present invention is further described in detail.
Traditional electric chain window opener is all to realize unlatching or the pass to vent window by forward and reverse rotation of motor
It closes, 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 state, therefore sash can not pass through chain window-opening machine quilt
It opens.The present invention is to consider when chain window-opening machine damages, and how the chain of chain window-opening machine leads to under sash connection status
It crosses servomechanism or manually opens sash.
As shown in Figure 1 to Figure 3, electric chain window-opening mechanism, including window frame 1, side are hinged on 2 and of sash on window frame 1
Chain window-opening machine 3, shell, actuating unit and chain 13 of the chain window-opening machine 3 including strip use has answered extensively in the market
Some prior arts repeat no more in present embodiment, 13 extended or retracted shell of actuating unit drive chain, chain 13
It stretches out from the side of shell and is connect with sash 2, the sides A1 of window frame 1 are equipped with lockset 7, as is illustrated by figs. 11 and 12, window frame 1
The installation of the sides B1 there are one can original place rotation the link block 9 with guide groove 8, which can be connected on axis on a holder 10,
The holder 10 is fixed on the sides B1 of window frame 1.Holder 10 is slightly tilted a little to the outside of window frame 1, in order to make the guide rod 6 on shell
Avoid window frame 1.Window frame 1 is hinged on perpendicular to ground, the downside of sash 2 on window frame 1.
The ends A2 of shell are locked by lockset 7；The ends B2 of shell are fixed with guide rod 6, and guide rod 6 passes through link block
9 guide groove 8；
As shown in Figures 4 to 6, under normal circumstances, sash 2 is opened or closed by electric chain window opener, electronic
The shell of chain window-opening machine is to maintain motionless, i.e. the ends A2 of shell are locked by lockset 7.Lockset 7 may be used electromagnetic lockset or
Non-firm power or bailout gas may be used in pneumatic lockset, electric power or air source herein, i.e., in abnormal cases, can still give lock
7 supply of tool.
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 ends A2 of shell 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 the B2 of shell
Guide rod 6 on end is moved along the guide groove 8 for the link block 9 being rotating, while link block 8 can follow guide rod 6 to occur
Rotation.
As shown in Figure 9 and Figure 10, the ends A2 of shell are fixed with pivot pin 11, and locked groove 12 is provided on lockset 7, in lockset 7
When locking the ends A2, pivot pin 11 is inserted into locked groove 12 and is locked by the locking bar of lockset 7 14；After lockset 7 unlocks, pivot pin 11 removes
Locked groove 12 so that the ends A2 of shell are in free state.
Servomechanism 5 is gas spring or spring push-rod, and servomechanism 5 gives sash 2 one active forces outwardly opened always.
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 dead weight.When applied to skylight, servomechanism 5 needs larger strength just can all to beat sash
It opens.
Actuating unit includes motor and reduction gearing, and motor is connect by reduction gearing with chain 13.Electric chain opens a window
Machine by the positive and negative rotation of motor come 13 outwardly directed length of drive chain, to open or close sash 2.
The section of guide rod 6 is round or rectangular, 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 in such a way that friction coefficient is less, to reduce friction when the two relative movement
Power.
As shown in Figure 7 and Figure 8, the length direction of shell of extending direction and chain window-opening machine of guide rod 6 is consistent.
As shown in Fig. 2, under 2 closed state of sash, 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 a
Principle and implementation of the present invention are described for example, and the explanation of above example is only intended to help to manage the present invention and core
Thought is thought.It should be pointed out that for those skilled in the art, without departing from the principle of the present invention,
Can be with several improvements and modifications are made to the present invention, these improvement and modification also fall into the protection domain of the claims in the present invention
It is interior.
