[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.
[0031] Please refer to Figure 1 - Figure 5, a cavity 2011 is provided inside one end of the rotating shaft 2001. One end of the second bidirectional screw 2008 penetrates through the positioning groove 2004 and extends into the cavity 2011, and a worm gear 2009 is sleeved thereon. A worm 2010 is rotatably connected to one side of the cavity 2011 near the worm gear 2009. The worm 2010 meshes with the worm gear 2009. An operation groove 2002 is provided on one side of the rotating shaft 2001 where the cavity 2011 is located. One end of the worm 2010 penetrates through the cavity 2011 and extends into the operation groove 2002, and a knob 2013 is sleeved thereon. A plug 2003 is provided on one side of the operation groove 2002. The plug 2003 is in interference fit with the operation groove 2002. The plug 2003 is made of rubber. By meshing the worm 2010 with the worm gear 2009, when the worm 2010 rotates, it can drive the worm gear 2009 to rotate, and then the second bidirectional screw 2008 and the first bidirectional screw 2006 also rotate accordingly. By providing the operation groove 2002 and extending one end of the screw 2010 into the operation groove 2002 and sleeving a knob 2013 thereon, the user can rotate the knob 2013 to make the worm 2010 rotate, so as to fix the connecting plate 1002 with the L-shaped insert block 2007. By making the plug 2003 in clearance fit with the operation groove 2002, it is convenient to block the operation groove 2002 to prevent dust from entering. By setting the plug 2003 to be made of rubber, it has a certain buffering effect to protect the knob 2013.
[0032] Specifically, the working principle of the electric rolling shutter door connection device is as follows: when in use, the user inserts the positioning plate 1003 installed on one side of the connecting plate 1002 into the positioning groove 2004 opened on one side of the rotating shaft 2001, and then the user pulls out the blocking block 2003 and turns the knob 2013. When the knob 2013 turns, the worm 2010 turns, and the worm 2010 meshes with the worm wheel 2009 sleeved on one end of the second bidirectional screw 2008, so that the second bidirectional screw 2008 turns, and the second bidirectional screw 2008 is connected to the first bidirectional screw 2006 through transmission, and when the second bidirectional screw 2008 turns, the first bidirectional screw 2006 also turns synchronously, so that the second bidirectional screw 2008 and the first bidirectional screw 2006 are connected. The slider 2012 threadedly connected to the screw rod 2008 and the first bidirectional screw rod 2006 at both ends moves relative to each other, and the slider 2012 is connected to the L-shaped plug block 2007, so that each pair of L-shaped plug blocks 2007 moves relative to each other, so that they are respectively engaged with the slots 1005 opened on both sides of the plug plate 1004, thereby completing the fixation of the connecting plate 1002. After the fixation is completed, the block 2002 is inserted into the operating groove 2002 again to protect the knob 2013. The worm wheel 2009 and the worm 2010 are self-locking, so the second bidirectional screw rod 2008 and the first bidirectional screw rod 2006 will not rotate during use, thereby improving the firmness of the connection between the connecting plate 1002 and the rotating shaft 2001.
