Abstract
The utility model relates to a double-directional hand operated apparatus for an electric rolling curtain door, which is suitable for being matched with garages without backdoors and electric rolling curtain doors which are used for decoration shop fronts of medium-sized and small-sized stores. When power supply trouble occurs under the condition of no standby power supply, the rolling curtain door can be totally started by hand operation indoors or outdoors. The utility model is formed by the method that a rolling drum which is provided with a driving device is connected with a fixing plate which is fixed on a wall, a lock case is fixed in an outdoor wall, and a power device is connected with the driving device; the driving device has the structure that an upper and a lower connecting rods, and the upper connecting rod is connected with a worm rod which is engaged with a worm wheel through an upper and a lower universal couplings, and the other end of the lower connecting rod is connected with a big gear; the power device has the structure that a shaft is connected with a gear box, one end of the power device is extended into the lock case, and the other end of the power device is connected with a handle and a small gear which is engaged with the big gear.
Description
The utility model relates to the main parts size in a kind of electric rolling door, this device be suitable for especially not having the back door garage and in, small shop does to decorate the supporting use of electric rolling door of the shop front.When power supply trouble taking place do not have standby electric power again, no matter can freely use the two-way hand gear of electric rolling door of hand starting rolling door at indoor or outdoors.
Along with development commercial, the housing construction industry, the usage quantity that does not occupy the electric rolling door of imitating usage space is more and more, and the kind of commercially available electric rolling door is more, except electronic and electronic telecontrol, some rolling door also has manual structure, but these manual structures are for pulling chain or pull the shank formula, and these manual structures only can be in indoor startup, also can't use outdoor, have significant limitation.
The purpose of this utility model is to provide a kind of electric rolling door two-way hand gear, in that power supply trouble takes place, does not have again under the situation of standby electric power, all can freely use the hand starting rolling door indoor, outdoor, and easy to use, rapid.
The utility model is achieved in that the two-way hand gear of electric rolling door, be connected with fixed head on being fixed on wall by the reel that has transmission device, and lock box is fixed in the outdoor wall, and power set be connected with transmission device form, described transmission device is on two, following universal coupling will be gone up, lower link reaches upward, and connecting rod is connected with the worm gear engaged worm, lower link end in addition connects and composes with gear wheel, described power set are that axle is connected with gear-box, and one end stretch out in lock box, and end is connected with handle and pinion respectively in addition, and pinion and gear wheel engagement formation.
Fig. 1. structural representation of the present utility model.
Fig. 2. the left view of Fig. 1.
Below in conjunction with accompanying drawing embodiment of the present utility model is further described:
Lock box (14) is inlayed with swell fixture and is fixed in the outdoor wall.
Fixed head (1) and two positioning seats (8) are fixed on the indoor wall with screw and swell fixture, and the gear-box (13) that two ends have copper sheathing is weldingly fixed on the iron plate of positioning seat (8) lower end wall.
Worm gear (2) is connected on the central axis of reel, and with casing in worm screw (3) engagement, the reel external fixation has an end of rolling door.
Out-of-line two upper and lower universal couplings (4), (6), reaching upper and lower connecting rod (5), (7) upward, connecting rod (5) is connected with worm gear (2) engaged worm (3), the end in addition of lower link (7) passes the annulus cover on two positioning seats (8), connects and composes transmission device with the gear wheel (9) (bevel gear) in cottor pin and the gear-box (13).
Axle (10) passes the copper sheathing and the wall at gear-box (13) two ends, one end stretches out in lock box (14), end is connected with pinion (12) (bevel gear) by flat key in addition, and pinion (12) and gear wheel (9) engagement also are connected with handle (11) on axle (10) termination and constitute power set.
When power supply trouble takes place, and when not having standby electric power, start rolling door at all available two-way hand gear of indoor or outdoors.If the people is indoor, at this moment with regard to rotatable handles (11), axle (10) is rotated, pinion on it (12) rotates, and the gear wheel (9) that drives with its engagement rotates, and changes rotation direction, become vertical rotation by original lateral rotation, rotate thereby drive upper and lower connecting rod (5), (7), make the reel rotation that fuses with worm gear (2) by worm screw (3) at last, then rolling door just can start and draws back.
If the people is outdoor, then available key is opened lock box (14), standby handle (11) is taken out from lock box (14), and handle (11) is inserted on the termination, the outside of axle (10), firmly shaking handle (11) rotates axle (10), then drive gear wheel (9) and rotate same as described abovely together, just rolling door can be drawn back or closed by pinion (12).
The utility model is compared with prior art: but because of mounting handle all at the two ends of axle, so indoor, Outdoor all can be two-way, with the hand swinging handle that is used as power, make the large and small bevel gear of beam warp change rotation direction, advance The row transmission has a power failure and the generation power supply trouble thereby make, and does not have in the situation of stand-by power supply, all can freely open Moving rolling screen door, easy to use, no limitation has alleviated labour intensity, otherwise will with manpower make the rolling screen door liter, Fall. Simultaneously its transmission device is fixed on the positioning seat on the wall, and be connected with upper and lower two not same Universal coupling on the straight line makes it all can automatically regulate in all directions, thereby rotates easily, uses peace Entirely, reliably, rapidly also laborsaving.
