Description
Technical field
The present invention relates to fire fighting device technical field, especially relating to one can open window opening device manually.
Background technology
Along with the raising of people's security against fire consciousness and standard-required, the use of building vent window window opening device gets more and more.But existing building vent window window opening device opening speed is low, it is time-consuming to open, and chain type window opening device is difficult to open under electroless state, not only cannot meet the requirement of fire protection rule, and more structural fire protection brings safely certain hidden danger.Therefore, exploitation is a kind of under electroless state or without in the abnormality situations such as fire-fighting signal, can be seemed particularly necessary by the chain type window opening device opened manually.
Summary of the invention
The object of this invention is to provide one and can open window opening device manually, it has also can ensure the feature that vent window can be opened smoothly under electroless state.
The technical solution adopted in the present invention is: can open window opening device manually, comprise casing, described casing is provided with slide rail, this slide rail slides and is provided with slide block, this slide block is connected with handle, and this slide block is fixed with worm and gear motor, simultaneously, this casing is also fixed with the train of reduction gears of the windowing component for connecting window opening device, this worm and gear motor and this train of reduction gears match.
Described casing is provided with chute, and this handle slides in this chute.
Described handle comprises the central tube connecting this slide block and the sleeve pipe being enclosed within this central tube outside, and meanwhile, the two ends of this chute are provided with locating hole, and the width of this chute is equal to the diameter of this central tube, and the internal diameter of this locating hole is same as the external diameter of this sleeve pipe.
Described slide block is furnished with the back-moving spring made it have near this train of reduction gears trend.
Described casing is provided with transition gear group, this transition gear group comprises the driving gear and driven gear that coaxially link together, and this driving gear has part degree of rotating freely relative to this driven gear, simultaneously, this driving gear is compatible with this worm and gear motor, and this driven gear engages this train of reduction gears.
The present invention is advantageously: under electroless state, also can ensure that vent window can be opened smoothly.The worm and gear motor can opening window opening device manually of the present invention can make this train of reduction gears obtain power near train of reduction gears under the drive of handle, then implements Electronic control to vent window.Meanwhile, under the drive of this handle, this worm and gear motor also can, away from this train of reduction gears, make this train of reduction gears not have power, and vent window can be opened voluntarily under self gravitation effect then.That is, achieve the operation of electronic and manual two kinds of modes of window opening device, not only make it meet fire protection rule requirement, more improve the security against fire level of building.

Detailed description of the invention
Embodiment, is shown in shown in Fig. 1 to Fig. 4: can open window opening device manually, comprises casing 10.This casing 10 is provided with slide rail 11.This slide rail 11 slides and is provided with slide block 20, this slide block 20 is connected with handle 21.That is, by handling this handle 21, this slide block 20 can be made to move along this slide rail 11.This slide block 20 is fixed with worm and gear motor 30.That is, this worm and gear motor 30 moves in company with this slide block 20.This worm and gear motor 30 generally includes motor, and the power output shaft of this motor is fixed with worm screw, and this worm screw is furnished with turbine, and this turbine realizes Power output.Meanwhile, this casing 10 is also fixed with the train of reduction gears 40 of the windowing component for connecting window opening device, this worm and gear motor 30 and this train of reduction gears 40 match.What is called matches herein, and referring to the associated components such as the turbine of this worm and gear motor 30 and the power input gear of this train of reduction gears 40 can engage, and this worm and gear motor 30 can make this train of reduction gears 40 have power then.Certainly, preferably mode is, this train of reduction gears 40 is positioned on the extension line of this slide rail 11.Wherein, the windowing component of this window opening device can be the parts such as the chain that vent window can be pulled to open or close, and this windowing component loosen after, this vent window can be opened under gravity voluntarily.Like this, after user handles this handle 21, this worm and gear motor 30 is connected with this train of reduction gears 40 power, along with the rotating forward of this worm and gear motor 30 and upset can realize the electronic of vent window and open or close; When without abnormalities such as electricity, only need oppositely to pull this handle 21, this worm and gear motor 30 to be moved and away from this train of reduction gears 40, this train of reduction gears 40 runs out of steam along with this slide block 20, and this vent window can be opened voluntarily under gravity or other power-assisted effects.
Shown in composition graphs 5 to Fig. 8, this casing 10 is provided with chute 12, and this chute 12 can be bar shaped, and this handle 21 slides in this chute 12.Like this, this handle 21 is made to have good operation trace.More excellent, this handle 21 comprises the central tube 211 connecting this slide block 20 and the sleeve pipe 212 being enclosed within this central tube 211 outside.Meanwhile, the two ends of this chute 12 are provided with locating hole 121, and the width of this chute 12 is equal to the diameter of this central tube 211, and the internal diameter of this locating hole 121 is same as the external diameter of this sleeve pipe 212.That is, this central tube 211 can slide in this chute 12, and once this handle 21 arrives the end of this chute 12, this sleeve pipe 212 can enter in this locating hole 121, realizes the locking of this handle 21.
Continue to optimize:
This slide block 20 is furnished with the back-moving spring 22 made it have near this train of reduction gears 40 trend.Like this, under normal circumstances, this worm and gear motor 30 and this train of reduction gears 40 is made to be in power connection status.
Shown in composition graphs 9 to Figure 11, this casing 10 is provided with transition gear group 50.This transition gear group 50 comprises the driving gear 51 and driven gear 52 that coaxially link together.This driving gear 51 has part degree of rotating freely relative to this driven gear 52.Such as, this driving gear 51 has scallop hole, this driven gear 52 has the shifting block be stuck in this scallop hole, this shifting block has activity surplus in this scallop hole, thus this driving gear 51 can drive this driven gear 52 to rotate, and can realize that this driving gear 51 rotates in advance and rotation delayed by this driven gear 52.The associated components such as meanwhile, this driving gear 51 is compatible with this worm and gear motor 30, the turbine namely on this worm and gear motor 30 can engage with this driving gear 51; This driven gear 52 engages the associated components such as the power input gear of this train of reduction gears 40.Like this, this train of reduction gears 40 and the disengaging of this turbine and worm motor 30, the life-span of connection procedure middle gear is extended.
The foregoing is only the preferred embodiments of the present invention; not thereby the scope of the claims of the present invention is limited; every utilize manual of the present invention and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
