Description
Technical field
The present invention relates to field of door and window accessories, and in particular to a kind of manually controllable electric window-opening machine.
Background technology
Electric window-opening machine is the equipment that can be automatically opened or closed window by motor-driven.But have a power failure or
The problem of will appear power breakdown or motor damage when fire, is driven speed since the power of motor of window opener is small at this time
Than it is big thus be difficult to manual switch sash, or even mutually killed between motor and retarder in special circumstances other, lead to nothing
The problem of method manual switch sash.
In order to solve the above-mentioned technical problem, Chinese patent literature CN105756461A discloses a kind of electricity that can be manually opened
Dynamic window opener, as shown in Figure 12 and Figure 13 comprising the chain being connect with forms, chain and sprocket engagement, sprocket wheel drive with motor
Dynamic worm gear mechanism connection, worm gear use detachable worm gearing；The detachable worm gearing packet
It includes with cogged axis 101, worm gear 102 is cased on the axis 101, install mandril 103 in axis, on worm gear 102 and the axis 101
Equipped with keyway；Key 104 is arranged in the keyway on worm gear and the axis, and side contacts or connects with mandril 103, other side setting
The spring assembly 105 for pushing key 104 to slide, key slides under the action of spring is with mandril, realize worm gear and axis from conjunction shape
State；The release device that setting implements pressure to mandril, puts action at the top of mandril.
Above-mentioned electric window-opening machine can push key move up and down by mandril, to control mutually nibbling for gear shaft and worm gear
It closes or separates, to complete the mutual switching between the motor switch of door and window and manual switch.But it is electronic in above-mentioned technology
Window opener needs to install spring 105, key 104 and mandril 103 to realize manual switch function, when manual switch door and window, needs
External force is wanted to press the elastic force that mandril makes key 104 overcome spring 105 always, to allow axis 101 and worm gear 102 to be separated from each other, to
It cuts off door and window and controls the connection of motor.Above structure need spring, key and mandril three cooperate could realize axis and
The engagement and separation of worm gear, and spring gets rusty easily failure, existing electric window-opening machine have it is complicated, installation maintenance at
This high problem.Also, axis and worm gear is set to detach due to needing to pin always mandril in manual operation, it is also necessary to other transmissions
Component pins always mandril, also improves the complexity and working service cost of electric window-opening machine.
New content
Therefore, the technical problem to be solved in the present invention is to overcome electric window-opening machine in the prior art, complicated
And the problem that installation maintenance is of high cost.
To solve above-mentioned technological deficiency, a kind of manually controllable electric window-opening machine provided by the invention, including：Driving machine
Structure has power unit, and is driven the deceleration unit being connected with the power unit；Clutch, including rotationally with institute
Driving mechanism is stated mounted on the same side of fan frame and is driven the driving member being connected with the deceleration unit, it is coaxial with the driving member
The clutch cover being rotatably connected, and the relatively described driving member are axially displaceably arranged for limiting the clutch cover position
