[0006] Preferably, the fixing plate forms a detachable structure with the mounting frame through fixing bolts, gaskets, nuts.

[0007] Preferably, the thickness of the sliding plate is smaller than the thickness of the gasket, and the sliding plate forms a sliding structure through the transmission wheel and the fixed plate.

[0008] Preferably, the transmission wheel forms a rotating structure with the sliding plate through the rotating shaft, and the transmission wheel is symmetrically arranged with respect to the central axis of the sliding plate.

[0009] Preferably, the transmission mechanism comprises an outer ring, marbles and an inner ring, the marbles are arranged on the inner side of the outer ring, and the inner ring is installed on the inner side of the marbles.

[0010] Preferably, the inner ring forms a rotating structure with the outer ring through the marbles, and the outer ring forms a detachable structure with the connecting plate, the mounting bolt and the sliding plate.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. By setting a sliding plate and plugging and installing the two ends of the winding shaft with the inner ring through a connecting rod, the winding shaft can be effectively and stably installed for subsequent winding operations. When the winding shaft rotates, the inner ring rotates stably and smoothly about the inner center of the outer ring through the marbles. The bearing setting can ensure the stability of the winding shaft following the rotation adjustment, which is convenient for smooth winding. The transmission mechanism is detachable between the connecting plate and the sliding plate, which is convenient for cleaning, maintenance, overhaul and replacement, and ensures stable use. At the same time, when winding, the sliding plate can slide stably along the outer side of the fixed plate through the transmission wheel. The four groups of transmission wheels ensure that they can fit stably with the fixed plate, improve the sliding stability, and ensure that the winding shaft can move back and forth through the setting of the sliding plate, which is convenient for automatic adjustment and conducive to winding operations. The fixed installation of the overall fixed plate ensures the stability and guidance of the sliding of the sliding plate, which is conducive to adjustment and use.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] Example 1

[0020] like Figure 1-3 As shown in the figure, a rolling shutter door transmission shaft structure that can move forward and backward includes a mounting frame 1, which is characterized in that: a fixing bolt 2 is installed on the inner wall of the mounting frame 1, a gasket 3 is installed through the outer side of the fixing bolt 2, a nut 4 is threadedly installed on the end of the fixing bolt 2, a fixing plate 5 is fixedly installed on the outer side of the fixing bolt 2, a sliding plate 6 is arranged between the rear side of the fixing plate 5 and the inner wall of the mounting frame 1, and transmission wheels 7 are arranged at both ends of the sliding plate 6, the transmission wheel 7 is arranged tangent to the side of the fixing plate 5, and the middle of the transmission wheel 7 is penetrated. A rotating shaft 8 is passed through and connected to the sliding plate 6, a connecting plate 9 is installed in the middle of the sliding plate 6, a positioning frame 10 is provided in the middle of the connecting plate 9, a transmission mechanism 11 is installed in the positioning frame 10, four corners of the connecting plate 9 are provided with mounting bolts 12 fixedly connected to the sliding plate 6, a connecting rod 14 is plugged and connected in the middle of the transmission mechanism 11, and a winding shaft 13 is integrated at the end of the connecting rod 14, a fixing rod 15 is provided at the inner bottom of the mounting frame 1, and a guide wheel 16 is rotatably installed on the outer side of the fixing rod 15.

[0021] The fixing plate 5 forms a detachable structure with the mounting frame 1 through the fixing bolt 2, the gasket 3, the nut 4, and the fixed installation of the whole fixing plate 5 ensures the stability and guidance of the sliding plate 6, which is convenient for adjustment and use.

[0022] The thickness of the sliding plate 6 is smaller than the thickness of the gasket 3 , and the sliding plate 6 forms a sliding structure with the fixed plate 5 through the transmission wheel 7 , ensuring that the sliding plate 6 can be slidably adjusted in the gap between the fixed plate 5 and the mounting frame 1 through the transmission wheel 7 .

[0023] The transmission wheel 7 forms a rotating structure through the rotating shaft 8 and the sliding plate 6, and the transmission wheel 7 is symmetrically arranged about the central axis of the sliding plate 6. The four groups of transmission wheels 7 ensure that they can fit stably with the fixed plate 5, improve the stability of sliding, and ensure that the winding shaft 13 can move forward and backward through the setting of the sliding plate 6.

[0024] The transmission mechanism 11 includes an outer ring 1101 , a marble 1102 and an inner ring 1103 . The marble 1102 is arranged on the inner side of the outer ring 1101 , and the inner ring 1103 is installed on the inner side of the marble 1102 .

[0025] The inner ring 1103 forms a rotating structure with the outer ring 1101 through the marble 1102, and the outer ring 1101 forms a detachable structure through the connecting plate 9, the mounting bolt 12 and the sliding plate 6. The inner ring 1103 rotates stably and smoothly about the inner center of the outer ring 1101 through the marble 1102, and the stability of the winding shaft 13 following the rotation adjustment can be ensured by the bearing setting.

[0026] Working principle: First, by plugging and installing the two ends of the winding shaft 13 with the inner ring 1103 through the connecting rod 14 respectively, the winding shaft 13 can be effectively and stably installed for the subsequent winding operation. When the winding shaft 13 rotates, the inner ring 1103 rotates stably and smoothly about the inner center of the outer ring 1101 through the marble 1102. The bearing setting can ensure the stability of the winding shaft 13 following the rotation adjustment, which is convenient for the smoothness of winding. The transmission mechanism 11 is detachable between the connecting plate 9 and the sliding plate 6, which is convenient for cleaning, maintenance, overhaul and replacement, and ensures stable use. At the same time, when winding, the sliding plate 6 can slide stably along the outer side of the fixed plate 5 through the transmission wheel 7. The four groups of transmission wheels 7 ensure that they can be stably fitted with the fixed plate 5, improve the sliding stability, and ensure that the winding shaft 13 can move back and forth through the setting of the sliding plate 6, which is convenient for automatic adjustment and conducive to winding operation. The fixed installation of the overall fixed plate 5 ensures the stability and guidance of the sliding of the sliding plate 6, which is conducive to adjustment and use.

[0027] Next, when rolling up the door curtain, the rotation setting between the guide wheel 16 and the fixed rod 15 can ensure that the equipment can effectively control the rolling up of the door curtain. At the same time, the guide transmission of the rolled-up door curtain can be effectively performed through the guide wheel 16, ensuring that the door curtain can be rolled up more stably and smoothly, and effectively preventing the door curtain from getting stuck due to the movement of the door curtain when moving forward and backward.
