detailed description

Below in conjunction with specific accompanying drawing and embodiment the utility model is further described.

As shown in the figure: the driving device for opening and closing the cover plate of the embodiment is mainly composed of a driving motor 1 and two sets of reduction transmission mechanisms connected thereto. It is arranged at the ends of both sides of the door panel assembly. The drive motor 1 is located between the two sets of reduction transmission mechanisms. The two output shafts of the drive motor 1 are respectively connected to the two sets of reduction transmission mechanisms through the synchronous shaft 2 .

As shown in Figures 1 to 5, in the embodiment of the utility model, the deceleration transmission mechanism is mainly composed of a reducer 3, an active flange shaft 4, a flange shaft bearing seat 5, a driven roller fixing plate 6, and a connecting arc Flange 7, connecting bearing sleeve 9, driving sprocket 10, steering sprocket shaft 11 and steering sprocket 12, the input shaft of the reducer 3 is connected with the output shaft of the drive motor 1, and the output shaft of the reducer 3 is installed with a driving The flange shaft 4, the front end of the active flange shaft 4 is installed in the flange shaft bearing seat 5 through bearing support, and the flange shaft bearing seat 5 is installed on the driven roller fixing plate 6; the middle part of the active flange shaft 4 An active flange 4a is provided, and the part of the active flange shaft 4 located in front of the active flange 4a is fitted with a connecting arc flange 7, a connecting bearing sleeve 9 and a driving sprocket 10, and the connecting arc flange 7 The outer periphery of the center is provided with two center-symmetric arc-shaped connecting channels, and the connecting arc-shaped flange 7 is connected with the driving flange 4a through sliding bolts 8 installed in the arc-shaped connecting channels; the driving sprocket 10 is fixedly installed on the driving flange shaft 4, the connecting bearing sleeve 9 is arranged between the connecting arc-shaped flange 7 and the driving sprocket 10, one end of the connecting bearing sleeve 9 is connected with the connecting arc-shaped flange 7, and the connecting bearing sleeve 9 The other end is connected with the driving sprocket 10; the steering sprocket shaft 11 is supported and installed on the driven roller fixed plate 6 through the bearing with seat 13, the steering sprocket shaft 11 is located above the driving flange shaft 4, and the steering sprocket shaft 11 is fixed Install the steering sprocket 12.

Working principle and working process of the present utility model are as follows:

The output shaft at both ends of the driving motor 1 transmits the power to the input shaft of the reducer 3 in the two sets of reduction transmission mechanisms. The reducer 3 reduces the speed and increases the torque, which is driven by the drive sprocket 10 installed on the drive flange shaft The pull chain rotates forward and reverse, and the pull chain drives the door panels connected to it to move, so that all the door panels move outward and turn over, and finally turn to 90 degrees, and the safety protection covers of the hanging object holes are all opened.

When the door panel of the safety protection cover plate of the hanging object hole is opened, it is necessary to break the equilibrium state of all folding doors. At this time, the traction chain will be displaced. Sliding occurs in the groove, eliminating the impact on the reducer 3 and the drive motor 1.
