Detailed Description
The following describes embodiments of the present invention with reference to the drawings.
As shown in fig. 1 to 3, a structure for easily mounting a motor of a roll screen door includes a fixing plate 1, a driving sprocket 5 and a driving shaft 31. The fixed plate 1 is used for connecting the transmission chain wheel 2 and the driving chain wheel 5 and fixedly connecting the roller shutter motor 3. Specifically, referring to fig. 4, the roller shutter motor 3 and the fixing plate 1 are fixed by connecting a nut 12 to the roller shutter motor 3 after a bolt 11 is inserted into the bottom surface of the fixing plate 1. The driving chain wheel 5 is connected to the position of the fixed roller shutter door motor 3 of the fixed plate 1, the transmission chain wheel 2 is connected to one side, away from the driving chain wheel 5, of the fixed plate 1, and the driving chain wheel 5 and the transmission chain wheel 2 are connected with the same chain 4 in an adhesion mode. The center of the driving chain wheel 2 is fixed to a driving shaft (not shown in the figure), the driving shaft is rotatably connected to the fixed plate 1, and the driving shaft penetrates through the fixed plate 1 and is fixedly connected with a scroll of the roller shutter door at the other side surface of the fixed plate 1, so that the roller shutter door motor drives the scroll to rotate, and the roller shutter door is rolled up and put down.
The drive sprocket 5 and the fixed plate 1 are connected by a fixing bolt 61 and a fixing nut 62. Referring to fig. 5 and 7, a first connection hole 13 is formed in the fixing plate 1, a recessed locking groove 51 is formed in the center of one end surface of the driving sprocket 5, the locking groove 51 has a polygonal cross section, and a second connection hole 53 penetrating into the locking groove is formed in the other end surface of the driving sprocket. The fixing bolt 61 is placed in the clamping groove 51 and passes through the first connecting hole 13 and the second connecting hole 53 to be in threaded connection with the fixing nut 62, and after the fixing nut 62 is connected and fastened, the bottom surface of the clamping groove 51 is limited between the fixing nut and the fixing plate 1 by the threaded head of the fixing bolt 61, so that the driving chain wheel 5 is limited, and the driving chain wheel 5 can only drive on the fixing plate 1.
Referring to fig. 5 and 6, in the connection structure between the driving sprocket 5 and the fixing plate 1, a placing groove 52 is formed in the bottom surface of the engaging groove 51 of the driving sprocket 5, the second connecting hole penetrates through the bottom surface of the placing groove 52, a bearing 63 is fixedly inserted into the placing groove 52 in an interference fit manner, a pressing ring 64 is further disposed in the second connecting hole 53, the height of the pressing ring 64 is greater than the depth of the second connecting hole 53, that is, after one end of the pressing ring 64 is pressed against the end surface of the inner ring of the bearing 63, the other end of the pressing ring 64 can extend out of the second connecting hole 53. During specific installation, the fixing bolt 61 is placed in the clamping groove 51, sequentially penetrates through the inner ring of the bearing 63, the pressing ring 64 and the first connecting hole 13 of the fixing plate 1 from top to bottom, and is in threaded connection with the fixing nut 62 for fastening. In this structure, clamping ring 64 can push up bearing 63 inner circle and drive sprocket 5 on fixed plate 1, keeps having the clearance with fixed plate 1, avoids drive sprocket 5 and fixed plate 1 to contact, and receive the restriction after fixing bolt 61 is fixed, bearing 63 is the fixed state relative fixed plate 1, makes drive sprocket 5 only can rotate on fixed plate 1, and the structure that bearing 63 connects can reduce drive sprocket 5 pivoted frictional force simultaneously to improve its transmission efficiency.
The driving shaft 31 is an output shaft of the shutter motor 3, or the driving shaft 31 is coaxially fixed to the output shaft of the shutter motor. The section of the driving shaft 31 is polygonal to fit the catching groove 51, and after the rolling door motor 3 is fixed to the fixing plate 1, the driving shaft 31 is inserted into the catching groove 51 of the driving sprocket 5 in a clearance fit manner. Preferably, the cross section of the locking groove 51 and the cross section of the driving shaft 31 are both hexagonal. In addition, the edge of the notch of the locking slot 51 is provided with an inclined guide surface 54, so that when the roller shutter motor 3 is installed, the driving shaft 31 can be more conveniently inserted into the locking slot 51 by the guide action of the guide surface 54.
After the structure of the oil adding device is adopted, the utility model discloses when installation rolling slats door motor 3, only need directly with rolling slats door motor 3 the drive shaft 31 orientation imbed in the draw-in groove 51 of driving sprocket 5, make each bolt 11 on the fixed plate 1 all pass rolling slats door motor 3's through-hole 32 simultaneously, later fasten nut 12 on bolt 11 can. That is, the utility model discloses an in the structure, when changing or maintaining roller shutter door motor 3, need not to take off drive sprocket 5, more need not to dismantle chain 4 and connect chain 4 again, very convenient.
The above-mentioned be the utility model discloses a concrete implementation way, nevertheless the utility model discloses a design concept is not limited to this, and the ordinary use of this design is right the utility model discloses carry out immaterial change, all should belong to the act of infringement the protection scope of the utility model.
