Description
Technical field
The utility model relates to a kind of portable closing device, particularly a kind of flat opening electric door.
Background technology
Flat opening electric door of the prior art comprises door leaf, door-hinge, open and close driver, roller and vertical carriage, opening and closing driver clutch end and roller is in transmission connection, roller and keying driver are installed on the door leaf by vertical carriage, therefore door can be mentioned, and cross dog back fixture block and by pirate of the open, the applicant has applied for a patent before this, (its application number is anti-pirate of the open flat opening electric door: 02220740.6), comprise door leaf stop device and the anti-device of carrying in the technical scheme that this patent disclosed, a kind of card wheel and a kind of click apparatus, the card wheel is in transmission connection by click apparatus and driver, and ratchet is installed on the card wheel, between card wheel and the door leaf a kind of first spring is installed, card wheel bottom has downward opening first groove, this first groove has bending segment, first fixture block in the fixture block can with the first groove clamping, the first groove bending segment can with the second groove clamping of first fixture block bottom, the structure relative complex of this card wheel, need accurate first groove and the bending segment on first groove and the clamping of adjusting on the card wheel of fixture block, processing is adjusted complicated.
Invention constitutes
The purpose of this utility model is to overcome weak point of the prior art and provides a kind of and can prevent the pirate of the open electric door and the more anti-pirate of the open flat opening electric door of structure.
The purpose of this utility model realizes by following approach.
Anti-pirate of the open flat opening electric door, comprise door leaf, door-hinge, roller, vertical carriage, the door leaf stop device, anti-device and the keying driver carried, its structural feature is: the door leaf stop device comprises a kind of throw-out lever and click apparatus, prevent that carrying device comprises a kind of fixture block and anti-cleaner bar, first spring is installed between throw-out lever and the door leaf, the ratchet of click apparatus is installed on the throw-out lever, anti-cleaner bar one end has bending segment, this bending segment can with the fixture block clamping, intermediate support is on door leaf, the other end then is connected with throw-out lever by a kind of first revolute pair, and ratchet and roller and keying driver are in transmission connection.
Like this, under the effect of first spring between throw-out lever and the door leaf, throw-out lever is pulled upwardly, ratchet and ratchet disengage, when door leaf turns to anti-cleaner bar and fixture block when colliding, anti-cleaner bar is withstood rotation by fixture block, and therefore, the other end of anti-cleaner bar pushes up throw-out lever downwards to lower swing and by first revolute pair, like this, thereby the ratchet on the throw-out lever moves down and ratchet engaged simultaneously, and ratchet is in transmission connection with opening and closing driver, therefore opens and closes the driver drives ratchet and rotates, therefore ratchet can make the throw-out lever that ratchet is installed continue top downwards, throw-out lever inserts the darker position of pothole, ground, opens and closes driver and stops, and door leaf cuts out.Because the bending segment and the fixture block clamping of anti-cleaner bar, door leaf can not be raised, throw-out lever inserts in the pothole on ground, door leaf can not be pushed, the mode of this mutual clamping has not only limited the rotation of door leaf, and the while also makes external force be difficult to upwards lift door leaf along vertical carriage because of the clamping of bending segment and fixture block.
In addition, when door leaf is opened, when the keying driver is worked at the beginning, the ratchet backward rotation, ratchet is creeped on hook tooth, extracts out in the pothole on ground thereby throw-out lever moves upward under the effect of first spring, therefore door leaf can move, anti-cleaner bar also breaks away from fixture block, and door leaf is opened, thus the complete overall process of closing and opening of door leaf.
The purpose of this utility model can also realize by following approach.
Ratchet and roller and keying driver are in transmission connection by transmission device, and transmission device comprises first transmission device and second transmission device, and first transmission device, one end is connected with the keying driver, and the other end is connected with second transmission device.
First transmission device is a kind of unidirectional transmission, and second transmission device is a kind of driving wheel and the homodromous transmission device of driven pulley, is fixed with ratchet on the driving wheel wheel shaft of second transmission device, is fixed with roller on the driven pulley wheel shaft.
First transmission device is a kind of unidirectional transmission, as worm and gear, the worm screw of worm and gear is connected with the output shaft that opens and closes driver, the driving wheel of worm gear drives second transmission device rotates, because therefore the characteristic of the unidirectional transmission of worm and gear is merely able to rotate by opening and closing driver drives second transmission device, after the keying driver stops, click will be locked and can not rotate, and therefore throw-out lever is fixed by click and can not be upspring.
Second transmission device is the moving in the same way transmission device of transporting of a kind of driving wheel and driven pulley, as sprocket wheel, is fixed with ratchet on the wheel shaft of the driving wheel of sprocket wheel, and ratchet and sprocket coaxiality rotate synchronously, are fixed with roller on the driven pulley wheel shaft of sprocket wheel.
The ratchet rear is hinged on throw-out lever, and second spring is installed between this ratchet and the throw-out lever.
Second spring is a kind of torsionspring.
This torsionspring can make ratchet and the ratchet on the card wheel break away from engagement and recover its position.
In addition, second spring also can be the compression spring, and the two ends of compression spring are connected with throw-out lever with ratchet, and ratchet is kept in touch with ratchet all the time.
First transmission can be a kind of slide way mechanism, and this slide way mechanism has chute and round pin, and chute is positioned on the anti-cleaner bar, and round pin is positioned on the throw-out lever, and round pin is placed in the chute.
The throw-out lever lower end has a through hole, and round pin is fixed in the inwall of this through hole.
The end that anti-cleaner bar has chute can pass this through hole, and chute is socketed on the round pin in the through hole simultaneously, and therefore, anti-cleaner bar can move up and down stirring throw-out lever when the supporting of centre is rotated.
First spring is a kind of compression spring.
First spring housing is connected on the upper end of throw-out lever, and the elasticity of spring makes throw-out lever be a kind of state of upwards carrying always, has only the drive of anti-cleaner bar or click just can make throw-out lever downward.
In addition, first spring also can be an extension spring, and extension spring one end is connected the upper end of throw-out lever, and the other end and door leaf are fixed, and can make throw-out lever remain a kind of state that makes progress equally.
The centre of anti-cleaner bar has through hole, and this through hole can be sleeved on the wheel shaft of roller.
Anti-cleaner bar can rotate around the through hole of centre.Anti-cleaner bar also can be enclosed within on other axle that is fixed on the door leaf, makes and prevents that cleaner can be around this rotation.
In sum, the utility model has the following advantages compared to existing technology: the anti-device of carrying of anti-pirate of the open flat opening electric door combines with stop device, by preventing that carrying device controls stop device simultaneously, anti-device and the stop device mutual restriction carried, keying drives the door leaf of not working and just can not rotate, have and effectively prevent the pirate of the open privately without opening and closing driver, and structure is simpler, production and processing is more simplified.
