DETAILED DESCRIPTION

[0026] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0027] like Figure 1 、 Figure 2 As shown, a single-motor translational skylight structure includes a base 1, a closing mechanism 2 is rotatably connected to the upper side of the base 1 near the rear side, a winding mechanism 3 is movably installed on the left and right sides of the inner side of the base 1, a moving mechanism 4 is slidably connected to the right side of the base 1 near the rear side, a power mechanism 5 is rotatably connected to the right side of the base 1, and a roller blind 6 is movably installed on the outer side of the winding mechanism 3.

[0028] It should be noted that the winding mechanism 3 includes components such as a conveying roller, a winding roller, and a guide roller. The conveying roller conveys and moves the rolling curtain 6, and the outer side of the rolling curtain 6 is wound and connected to the winding roller.

[0029] like Figure 2 、 Figure 3 As shown, the closing mechanism 2 includes a first baffle 21, the upper side of the first baffle 21 is rotatably connected to the upper side of the base 1 near the rear side, the lower side of the first baffle 21 is rotatably connected to the second baffle 22, and the outer side of the base 1 near the bottom is movably sleeved in the groove formed by the first baffle 21 and the second baffle 22, and the left and right sides of the base 1 near the front and rear edges are rotatably connected with four rectangularly distributed fixing components 23, the fixing component 23 includes a rotating plate 231, the side of the rotating plate 231 near the winding mechanism 3 is rotatably connected to the bosses on the left and right sides of the base 1 near the front and rear sides, and the rotating plate 231 is located on the side of the second baffle 22 and the first baffle 21 away from the winding mechanism 3.

[0030] It should be noted that the rotating plate 231 blocks the first baffle 21 and the second baffle 22 so that the positions of the first baffle 21 and the second baffle 22 are fixed. Rotating the rotating plate 231 can quickly release the restrictions of the first baffle 21 and the second baffle 22.

[0031] like Figure 2 、 Figure 3 As shown, the outer side of the rotating plate 231 is movably sleeved with a pull rod 232, and the outer side of the pull rod 232 is movably sleeved with a spring 233, and the spring 233 is located on the inner side of the left and right side bosses of the base 1, and the outer side of the pull rod 232 is fixedly connected with a polygonal plate 234, and the polygonal plate 234 is movably sleeved in a polygonal groove opened on the side of the rotating plate 231 close to the winding mechanism 3, and the polygonal plate 234 is fixedly connected to two annularly distributed clamping shafts 235 at a position near the edge of the side close to the winding mechanism 3, and the outer side of the clamping shaft 235 is movably sleeved in the socket opened on the left and right side bosses of the base 1.

[0032] It should be noted that when the card shaft 235 is movably sleeved into the socket, the rotating plate 231 cannot rotate. Pulling the pull rod 232 causes the card shaft 235 to be separated from the socket, so that the rotating plate 231 can rotate.

[0033] like Figure 2 、 Figure 3 As shown, a clamping plate 236 is fixedly connected to the upper side of the rotating plate 231 , and the outer side of the clamping plate 236 close to a wall of the winding mechanism 3 is movably sleeved into the clamping holes on the left and right sides of the base 1 near the front and rear sides.

[0034] It should be noted that the clamping plate 236 is used to fix the rotating plate 231, so that the first baffle 21 and the second baffle 22 cannot rely on their own gravity or other force to push the rotating plate 231, thereby enhancing the fixing ability of the rotating plate 231 to the first baffle 21 and the second baffle 22.

[0035] like Figure 2 、 Figure 4 and Figure 5 As shown, the moving mechanism 4 includes a moving plate 41, the left side of the moving plate 41 is slidingly connected to the right side of the base 1 near the upper rear side, the lower side of the moving plate 41 is fixedly connected to a bevel rack 42, the lower side of the bevel rack 42 is meshingly connected to a worm 43, and the outer front and rear ends of the bevel rack 42 are rotatably connected to the right side of the base 1 near the upper rear side.

[0036] It should be noted that rotating the worm 43 causes the worm 43 to drive the bevel rack 42 to move forward and backward, causing the bevel rack 42 to drive the movable plate 41 to move forward and backward. Due to the self-locking effect between the worm 43 and the bevel rack 42, the worm 43 can synchronously fix the movable plate 41.

[0037] like Figure 5 、 Figure 6As shown, the rear end of the worm 43 is fixedly connected to a round rod 44, and the outer side of the round rod 44 is rotatably connected to a fixing seat 45 near the rear end. The left side of the fixing seat 45 is fixedly connected to the right side of the base 1 near the upper rear side, and the outer side of the round rod 44 is threadedly connected to a screw 46 near the rear side. A number of annular fixing holes 47 are provided on the right side of the fixing seat 45, and the outer side of the screw 46 is movably sleeved on the inner side of the screw 46.

[0038] It should be noted that when the screw 46 is located inside the fixing hole 47 , the round rod 44 is fixed, so that the round rod 44 cannot rotate. Removing the screw 46 allows the round rod 44 to rotate.

[0039] like Figure 2 、 Figure 4 As shown, the power mechanism 5 includes a motor 51, the left side of the motor 51 is fixedly connected to the right side of the movable plate 41, the right side of the base 1 near the front lower side is rotatably connected to the first gear 52, the right side of the base 1 near the lower side is rotatably connected to the second gear 53, the front side of the second gear 53 is meshed with the rear side of the first gear 52, the output end of the motor 51 is fixedly connected to the first pulley 54, the right side of the first gear 52 is movably installed with a second pulley 55, and the inner sides of the first pulley 54 and the second pulley 55 are meshed with a transmission belt 56.

[0040] It should be noted that the motor 51 drives the first pulley 54 to rotate, and the second pulley 55 contains a first one-way component, so that the second pulley 55 can drive the first gear 52 to rotate counterclockwise, but cannot drive the first gear 52 to rotate clockwise. The second pulley 55 is driven to rotate by the transmission belt 56, and the left side of the second gear 53 is fixed to the right side of the winding roller on the winding mechanism 3.

[0041] like Figure 2 、 Figure 4 As shown, the right side of the base 1 is rotatably connected to the position near the front upper side, and the right side of the base 1 is rotatably connected to the position near the front upper side. The front side of the fourth gear 58 is meshed and connected with the rear side of the third gear 57. The right side axis of the fourth gear 58 and the right side axis of the second pulley 55 are fixedly connected with a sprocket 59, and the side of the sprocket 59 is meshed and connected with a chain 510.

[0042] It should be noted that a second one-way component is provided between the sprocket 59 and the fourth gear 58, so that when the roller shutter 6 is extended, the sprocket 59 can drive the fourth gear 58 to rotate, and when the roller shutter 6 is retracted, the sprocket 59 is idle, and the sprocket 59 cannot drive the fourth gear 58 to rotate. The motor 51 drives the sprocket 59 on the rear side to rotate, and relies on the chain 510 to cause the sprocket 59 on the front side to rotate. When the sprocket 59 rotates, it drives the fourth gear 58 to rotate, and when the fourth gear 58 rotates, it drives the third gear 57 to rotate. The left side of the third gear 57 is fixedly connected to the conveying roller on the winding mechanism 3, so that the third gear 57 drives the conveying roller on the winding mechanism 3 to rotate, so that the conveying roller drives the roller shutter 6 to transmit.

[0043] The working principle of the present invention is as follows: First, the motor 51 drives the first pulley 54 to rotate, and the second pulley 55 contains a first one-way component, so that the second pulley 55 can drive the first gear 52 to rotate counterclockwise, but cannot drive the first gear 52 to rotate clockwise, and relies on the transmission belt 56 to drive the second pulley 55 to rotate. The left side of the second gear 53 is fixed to the right side of the winding roller on the winding mechanism 3. A second one-way component is provided between the sprocket 59 and the fourth gear 58, so that when the rolling curtain 6 is extended, the sprocket 59 can drive the fourth gear 58 to rotate. When the rolling curtain 6 is retracted, the sprocket 59 rotates idly, and the sprocket 59 cannot drive the fourth gear 58 to rotate. The motor 51 drives the sprocket 59 on the rear side to rotate, and relies on the chain 510 to cause the sprocket 59 on the front side to rotate. When the sprocket 59 rotates, it drives the fourth gear 58 to rotate. When the fourth gear 58 rotates, it drives the third gear 57 to rotate. The left side of the third gear 57 is fixedly connected to the conveying roller on the winding mechanism 3, causing the third gear 57 to drive the conveying roller on the winding mechanism 3 to rotate, so that the conveying roller drives the rolling curtain 6 to transmit. The second gear 53 and the third gear 57 are driven to rotate by the motor 51. The setting of the chain 510 makes the moving mechanism 4 convey the rolling curtain 6 forward in a consistent manner. The setting of the transmission belt 56 causes the second gear 53 to idle, because the transmission belt 56 is connected by friction and can allow a certain speed difference. When there is a speed difference, the first gear 52 will slow down or pause, waiting for the speed of the rolling curtain 6 to be gathered close to the lap speed of the rolling curtain 6, resulting in the speed being back and forth. The first and second baffles 21 and 22 are fixed in position by rotating the rotating plate 231. The restrictions of the first and second baffles 21 and 22 can be quickly released by rotating the rotating plate 231. When the card shaft 235 is movably sleeved into the socket, the rotating plate 231 cannot be rotated. The pull rod 232 is pulled to cause the card shaft 235 to be disengaged from the socket, so that the rotating plate 231 can be rotated. The card plate 236 is used to fix the rotating plate 231, so that the first and second baffles 21 and 22 cannot rely on their own gravity or other force to push the rotating plate 231, thereby enhancing the fixing ability of the rotating plate 231 to the first and second baffles 21 and 22. 22 is fixed, the card shaft 235 and the card plate 236 fix the rotating plate 231, so that the first baffle 21 and the second baffle 22 are quickly fixed, so that the first baffle 21 and the second baffle 22 can be quickly installed and removed, so as to facilitate opening the interior of the base 1 and facilitate maintenance of the structure. Finally, the worm 43 is rotated, so that the worm 43 drives the bevel rack 42 to move back and forth, so that the bevel rack 42 drives the movable plate 41 to move back and forth. Due to the self-locking effect between the worm 43 and the bevel rack 42, the worm 43 can synchronously fix the movable plate 41. When the screw 46 is located on the inner side of the fixing hole 47, the round rod 44 is fixed, so that the round rod 44 cannot rotate. Remove the screw 46 so that the round rod 44 can rotate.By rotating the worm 43, the motor 51 moves left and right, so as to quickly adjust the tightness of the transmission belt 56 and the chain 510, making the installation and removal of the chain 510 and the transmission belt 56 more convenient, and at the same time, the friction between the transmission belt 56 and the pulley can be quickly controlled.
