Detailed Description

The accompanying drawings, which are incorporated in and constitute a part of this application, illustrate preferred embodiments of the invention and together with the description, serve to explain the principles of the invention and not to limit the scope of the invention.

Referring to fig. 1, the manual door opening mechanism of an industrial door opening machine according to an embodiment of the present invention includes a motor 1, a sprocket mechanism 2, a transmission shaft 3, a guide wheel 4, a guide pin 5, a driving transmission member 6, a driven transmission member 7, a reset member 8, and a friction plate 9.

Sprocket mechanism 2 with transmission shaft 3 fixed connection, transmission shaft 3 passes initiative driving medium 6, leading wheel 4 and friction disc 9 and with initiative driving medium 6 fixed connection, uide pin 5 inserts in transmission shaft 3, and for transmission shaft 3 is perpendicular, the inside cavity of leading wheel 4, leading pin 5 is located the inside of leading wheel 4, the first terminal surface 4a of leading wheel 4 be used for with leading pin 5 butt, the second terminal surface 4b of leading wheel 4 with friction disc 9 contact each other, transmission shaft 3, leading wheel 4, uide pin 5, initiative driving medium 6, driven transmission medium 7, the piece 8 that resets all are located the inside of a casing 10, friction disc 9 with casing 10 is fixed, transmission shaft 3 has a arch 31, the piece 8 cover that resets is established on transmission shaft 3, one end of the reset piece 8 is abutted to the protrusion 31, and the other end of the reset piece 8 is abutted to the inner wall of the shell 10.

Particularly, under the external force is driven, sprocket mechanism 2 drives transmission shaft 3 rotates, when transmission shaft 3 rotates, uide pin 5 is in the first terminal surface 4a of leading wheel 4 moves on, so that transmission shaft 3 carries out the axial motion back, makes driving transmission member 6 with driven transmission member 7 cooperation, and the compression resets 8, driving transmission member 6 along with when transmission shaft 3 rotates, can drive driven transmission member 7 rotates, so that the output shaft of motor 1 rotates.

In other words, in the state of opening the door electrically, the door opening action is realized by the action of the output shaft of the motor 1, the reset member 8 is in a natural state, the driving transmission member 6 is not in contact with the driven transmission member 7, so the manual door opening mechanism cannot be operated by the rotation of the motor 1, when the motor 1 is powered off, the output shaft of the motor 1 cannot automatically rotate and needs to be driven by external force, the sprocket mechanism 2 is manually rotated, the sprocket mechanism 2 can drive the transmission shaft 3 to rotate, when rotating, the guide wheel 4 is fixed and does not move due to the action of the friction plate 9, the guide pin 5 can move along the first end surface 4a of the guide wheel 4 along with the rotation of the transmission shaft 3, and when the guide pin 5 moves on the first end surface 4a, the transmission shaft 3 can be driven to axially move, when the driving transmission member 6 and the driven transmission member 7 are mutually matched, the guide pin 5 also moves to the limit position of the first end surface 4a, at this time, along with the rotation of the transmission shaft 3, the guide wheel 4 overcomes the friction force with the friction plate 9, and then the guide wheel 4 and the transmission shaft 3 rotate together, so that the transmission shaft 3 does not axially move any more, and the resetting member 8 is compressed; with the continuous rotation of the transmission shaft 3, the driving transmission part 6 rotates along with the transmission shaft 3, so as to drive the driven transmission part 7 matched with the driving transmission part to move together, the driven transmission part 7 drives the output shaft of the motor 1 to rotate, so that the door opening action is realized, after the door opening is finished, no external force drives the chain wheel mechanism 2, and the reset part 8 automatically resets at the moment, so that the transmission shaft 3 performs reverse axial movement, and all the parts are restored to the original positions.

According to the invention, the door opening action is realized without driving the motor to move in a manual mode, so that when the door is opened manually due to a fault, the switching of the door opening mode is not required, the chain wheel mechanism 2 can be directly operated to realize the door opening, and the door opening is simple and convenient.

In a preferred embodiment, with continuing reference to fig. 1, the sprocket mechanism 2 includes a sprocket 21 and a chain 22, a center of the sprocket 21 is fixedly connected to the transmission shaft 3, and the chain 22 is wound around the sprocket 21 and drives the sprocket 21 to rotate.
