Abstract

The utility model relates to an electric-door driver with a clutch mechanism. The prior driving device consists essentially of the parts of a decelerating motor, a driving gear, a driven gear etc., and when the power is cut or the power is disconnected, the electric door of the kind can hardly be opened or closed by manpower, because the decelerating motor has the function of reversely and automatically locking, which brings inconvenience and trouble to the user. The utility model has the characteristics that a decelerating motor is movably connected inside a casing body; the inside of the casing body is provided with a resetting unit and a cam which match with the decelerating motor; the cam is provided with a driving handle. The cam, the driving handle and the resetting unit form a clutch mechanism. When the power is cut or the power is disconnected, the driving gear can depart from the mesh with the driven gear just by pulling the driving handle, and then the electric door can be opened and closed by manpower. The utility model is convenient and prompt for operating and saves time and labor.

Description

The electric gate driver of band clutch

[technical field]

The utility model relates to a kind of drive unit of building electric door, particularly with the electric gate driver of clutch.

[background technology]

Raising along with development and national economy and living standards of the people, on buildings such as factory building, shop, gradually incompatibility people's the requirement of manual rolling door that traditional employing common aluminum alloy is made, especially at carbarn, as the ancillary facility of the high-grade vehicles, aforementioned rolling door is more apparent having fallen behind just.So various types of electric door are arisen at the historic moment, such as slide on the flap that is used on the garage and automatic panel-turnover door.Slide and automatic panel-turnover door on the present flap normally are power with the drive unit, drive electric door by driving members such as chain, gear, belts again and make its unlatching or close.Wherein drive unit is mainly by reducing motor, driving gear, driven gears etc. are partly formed, this electric door is under the normal power supply situation, can be according to the Push And Release of remote control or manual command control electric door, but run into when having a power failure or cutting off the power supply, common way is to get off directly to open with manpower, close electric door, but because reducing motor has reverse self-lock ability, i.e. rotation by the reducing motor rotating shaft drives power or the moment that electric door only need be less, opposite, want to make the rotating shaft rotation of reducing motor then so easy by electric door being applied power or moment, or even it is impossible, therefore, just be difficult to electric door is opened or closed, make troubles and bother to the user.

[utility model content]

The technical assignment of the technical problems to be solved in the utility model and proposition provides a kind of (break) normal switch electric door when electric that can guarantee to stop, and uses the electric gate driver of more convenient reliable band clutch.

The technical scheme that the utility model is taked is: the electric gate driver of band clutch, comprise housing, be positioned at reducing motor, the driving gear on the reducing motor of housing and the driven gear that cooperates with driving gear, the output shaft of described driven gear extends outside the housing, it is characterized in that described reducing motor is actively socketed in the housing; Be provided with the return unit and the cam that cooperate with reducing motor in the housing, cam is provided with driving handle.Wherein driving gear is fixed on the reducing motor, and the output shaft of driven gear connects driving member.Generally, return unit makes driving gear and driven gear keep engagement to the reducing motor application of force, only needs as required can open or close electric door by remote control or manual command; When having a power failure or cut off the power supply, pull driving handle and make reducing motor swing an angle, and then make the engagement of driving gear disengaging and driven gear, again with the direct open and close electric door of manpower by cam, just be not subjected to the restriction of the reverse self-lock ability of reducing motor, successfully electric door opened or closed.

As further optimization to technical solutions of the utility model, can be with the oscillating deck that is coupling in the housing, reducing motor is fixed on the oscillating deck; Cam is located at a side of oscillating deck by rotating shaft; The cam outer end is a ratchet, and the inner of driving handle is provided with the ratchet that cooperates with ratchet; Rotating shaft is provided with the handle reduction torsion spring, is used to make driving handle to automatically reset; With being located at stage clip between housing and the oscillating deck as return unit; Be provided with the position limited gear that meshes with driven gear in the housing, connect locating part on the position limited gear, be used for when electric door moves to desired location, stopping automatically the work of reducing motor; The housing of driving handle both sides is provided with limited block, is used for driving handle is limited in certain scope of activities.

The utility model is set up a clutch on existing electric gate driver, generally, make driving gear and driven gear keep engagement, only needs as required can open or close electric door by remote control or manual command; And when having a power failure or cut off the power supply, pull the engagement that driving handle can make driving gear disengaging and driven gear, and come the open and close electric door with manpower again, convenient to operation, time saving and energy saving.The position-limit mechanism of electric door has been simplified in the setting of position limited gear, and is simple and reliable for structure, complete function.

Fig. 2 is the right view of Fig. 1.

Fig. 3 is the schematic diagram of the utility model clutch state.

[specific embodiment]

As shown in the figure, the electric gate driver of band clutch is that intermeshing driven gear 4 and position limited gear 5 are installed on housing 1 base plate, and the output shaft of driven gear 4 extends outside the housing; Oscillating deck 2 is connected on housing 1 base plate by bolt 13, and reducing motor 7 is fixed on the oscillating deck 2, driving gear 3 on the reducing motor 7 and driven gear 4 engagements; Cam 8 is connected by rotating shaft 9 on the housing base plate of oscillating deck 2 one sides, and cam 8 outer ends are ratchet 15, and the inner of driving handle 11 is provided with the ratchet 12 that cooperates with ratchet; The outer end of driving handle 11 extends outside the housing, and the housing of driving handle both sides is provided with limited block 14; Also be provided with handle reduction torsion spring 10 in the rotating shaft 9.Be located between housing and the oscillating deck as the stage clip of return unit 6.

Generally, cam 8 is inoperative, and stage clip makes driving gear 3 and driven gear 4 engagements then to oscillating deck 2 application of forces, can open or close electric door by transmission mechanism by starting reducing motor 7; When power failure or short electricity, pull driving handle 11 downwards, make cam 8 strut oscillating deck 2, driving gear 3 meshes with driven gear 4 disengagings, is in clutch state, and promptly can directly open or close electric door by manpower this moment.
