Description
Technical field
The present invention relates to the rolling door technical field, relate to a kind of manual roller blind device that is used for electric rolling door in particular.
Background technology
At present, what a lot of StoreFronts, garage adopted all is rolling door, and especially door opening is bigger, and the place of ground door body is installed in inconvenience, and rolling door can play convenient, fast unlatching effect.Rolling door is divided into two kinds of manual rolling door and electric rolling doors; Manually rolling door is as the term suggests be exactly to adopt manual roller blind device to realize the unlatching of rolling door, close, and for example the patent No. is the utility model patent of ZL200820115109.X, just discloses a kind of manual roller blind device; Manual roller shutter takes time and effort, speed is slow; So much human all adopts electric rolling door, for example patent No. ZL2010206655803, the applying date are described a kind of electric rolling door on December 17th, 2010, and it rotates with roller shutter driven by motor roller shutter central axis; Realize the switch of roller shutter, open, close very fast.But when having a power failure, the roller shutter motor can't be worked, for this reason; Electric rolling door all is provided with manual roller blind device, can when having a power failure, adopt manually openedly, closed to the volume the inside, and for example the patent No. is that the Chinese utility model patent of ZL99228165.2 just discloses a kind of manual, electronic rolling door spool convenient to both, can realize manual, electronic two kinds of functions of rolling door; But such rolling door need be inserted security key in the safety vent when carrying out electronic, manual switch, can realize the action of manual roller shutter; Cumbersome, in case motor gets electricly in manual procedure, can damage the operator, have very large potential safety hazard; And, after manually finishing, need manual security key is extracted from safety vent; More time-consuming, effort in case forget, also have bigger danger.
Summary of the invention
The objective of the invention is weak point, a kind of manual roller blind device that is used for electric rolling door is provided, directly rotate the work that drive just can be realized manual roller shutter to prior art; After stopping manual roller shutter; Can realize automatically and the clutch of roller shutter central axis that do not need manually just can realize both separation, whole process is very convenient; Time saving and energy saving, fool proof.
In order to solve the problems of the technologies described above; Technical scheme of the present invention is following: a kind of manual roller blind device that is used for electric rolling door; Comprise bearing, vertical output shaft; Be installed in horizontal axis of rotation on the said bearing; Coaxial drive and the horizontal bevel gear of being fixed with on the said horizontal axis of rotation; Vertical bevel gear is installed on the said vertical output shaft, also is equipped with on the said horizontal axis of rotation and when said drive drives on the said horizontal axis of rotation rotation, said horizontal axis of rotation is axially moved and then make axial moving device that said horizontal bevel gear is meshed with said vertical bevel gear and can make said horizontal bevel gear and resetting means that said vertical bevel gear is separated and comes.
Manual roller blind device of the present invention when needs are manual, directly rotates drive, makes horizontal axis of rotation rotate; Move axially simultaneously, make horizontal bevel gear be meshed, drive vertical output shaft and make the roller shutter central axis rotate with vertical bevel gear; And then realize after manual roller shutter finishes, unclamping drive by manual roller shutter; Under the effect of resetting means, make horizontal bevel gear and vertical bevel gear break away from automatically, whole process is quick, convenient, safety very; Do not need after the completion to carry out any manual clutch action again, need not carry out any connection work before the completion yet, only need the rotation drive can realize the roller shutter action.
As preferably, said axial moving device comprises the outer clutch discs that is sleeved on the said horizontal axis of rotation, be installed in the said outer clutch discs and the side have interior clutch discs along axially extended first inclined plane, to clutch discs said outside exert pressure make said outer clutch discs and said interior clutch discs generation frictional force the portion that exerts pressure, be used to limit said outside the sliding part that matches with said first inclined plane of the limiting section that axially moves of clutch discs, interior clutch discs and being used for.
As preferably, said in clutch discs be sleeved on the said horizontal axis of rotation, said sliding part is fixed on the said horizontal axis of rotation.
As preferably, said in clutch discs and said horizontal axis of rotation be solidly fixed, said sliding part is fixed on the said outer clutch discs.
As preferably, said in the clutch discs side be provided with along axially extended second inclined plane, said second inclined plane and intersection, said first inclined plane form a groove.
As preferably, said first inclined plane and/or second inclined plane are provided with spring cavity along axially extended top end, and the compression spring is installed in the said spring cavity.
As preferably, said resetting means comprises and can produce and the first inclined plane bearing of trend spring, the support portion that said spring is supported of opposite force mutually said horizontal axis of rotation.
As preferably, there is the end axle of a diameter less than said horizontal axis of rotation the end of said horizontal axis of rotation, and said spring housing is contained on the said end axle, and said spring one end contacts with the end face of said horizontal axis of rotation, and the other end contacts with said support portion.
As preferably, be provided with a torsion spring between said vertical bevel gear and the said vertical output shaft, said vertical bevel gear is installed on the said vertical output shaft through pin, has the chute along circumferential extension that matches with said pin on said vertical bevel gear.
As preferably, comprise that also one moves axially, makes said horizontal bevel gear to be meshed with said vertical bevel gear can to make before the microswitch that the roller shutter motor of electric rolling door cuts off the power supply when said horizontal axis of rotation.
The existence of microswitch makes that whole device is safer, because; Move axially at horizontal axis of rotation, make horizontal bevel gear with before vertical bevel gear is meshed, microswitch just can make the roller shutter motor of electric rolling door cut off the power supply; Like this; Can prevent that the roller shutter motor is electricly unexpected in manual roller shutter way, cause the operator to damage, guarantee user's safety.
Beneficial effect of the present invention is:
Manual roller blind device of the present invention can carry out the action of manual roller shutter easily, directly utilizes rotation drive such as chain to get final product; Other action need be do not carried out, after stopping manual roller shutter, clutch can be realized automatically with the central rotating shaft of rolling door; Do not need manually yet; Whole process is very convenient, time saving and energy saving, fool proof.
And, manually can cut off the power supply to the roller shutter motor in the roller shutter, prevent that motor is electricly and cause the rotation of central rotating shaft unexpected, cause operator's damage, guaranteed operator's safety, eliminated potential safety hazard.
