[0030] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0031] Embodiment 1:

[0032] like Figure 1-3 As shown, a rolling shutter door guide groove structure includes a guide frame 1.

[0033] A support frame 2 is arranged on the inner side of the guide frame 1, and a fixed block 3 is fixedly connected to the inner wall of the support frame 2 through a fixed rod 15. Both ends of the fixed block 3 are rotatably connected to a connecting frame 5 through an axis 1 4, and the other end of the connecting frame 5 is rotatably connected to a roller 11 through an axis 4 10. The roller 11 is in rolling contact with the inner wall of the guide frame 1, and a threaded rod 12 is slidably fitted on the inner wall of the fixed block 3. A connecting block 9 is fixedly connected to the bottom of the threaded rod 12. Both ends of the connecting block 9 are rotatably connected to a connecting rod 7 through an axis 3 8, and the other end of the connecting rod 7 is rotatably connected to the inner wall of the connecting frame 5 through an axis 2 6.

[0034] As the roller 11 is in constant contact and friction with the inside of the guide frame 1, it will cause wear. When the threaded rod 12 drives the connecting block 9 to move downward, the connecting rod 7 drives the connecting frame 5 to open outward, thereby driving the roller 11 to move outward, ensuring that the roller 11 is always in reliable contact with the inner wall of the guide frame 1.

[0035] The device is provided with a connecting frame 5, a connecting rod 7, a connecting block 9 and a threaded rod 12. When the connecting block 9 moves downward with the threaded rod 12, the connecting rod 7 is used to drive the connecting frame 5 to open outward, thereby driving the roller 11 to move outward, compensating for the wear of the roller 11, ensuring that the roller 11 can always be in reliable contact with the inner wall of the guide frame 1, avoiding damage to the rolling shutter door.

[0036] In this embodiment, the outer wall of the threaded rod 12 is connected to a sleeve 13 via threads, and the top of the sleeve 13 is rotatably connected to the lower surface of the top of the support frame 2.

[0037] The outer wall of the top of the sleeve 13 is fixedly connected with a torsion spring 14 , and the other end of the torsion spring 14 is fixedly connected to the inner wall of the support frame 2 .

[0038] After the roller 11 is worn, its diameter becomes smaller. At this time, the torsion spring 14 provides a rotational force for the sleeve 13, so that the threaded rod 12 moves longitudinally, thereby cooperating with the connecting block 9 to drive the connecting rod 7 and the connecting frame 5 to open outward, driving the roller 11 to contact the inner wall of the guide frame 1.

[0039] The device is provided with a sleeve 13 and a torsion spring 14, and utilizes the torsion spring 14 to provide a rotational force for the sleeve 13, so that after the roller 11 is worn, the torsion spring 14 can drive the sleeve 13 to rotate, and the sleeve 13 and the threaded rod 12 are connected by threads, so that the threaded rod 12 can move longitudinally and realize reverse self-locking to prevent the connection from loosening.

[0040] like Figure 3 As shown, a guide rail 16 for limiting the position of the roller 11 is fixedly connected to the inner wall of the guide frame 1 .

[0041] The guide rail 16 can provide a limiting guiding function for the roller 11 to prevent the roller 11 from being displaced when rolling along the inner wall of the guide frame 1, thereby ensuring the stability of the rolling door.

[0042] like Figure 4 As shown, a plurality of symmetrically arranged mounting plates 17 are welded to the side wall of the support frame 2 , and mounting grooves 18 are formed on the inner wall of the mounting plate 17 .

[0043] The rolling shutter door is placed on the opposite side of the two mounting plates 17, and then a hole with the same diameter as the mounting groove 18 is drilled on the rolling shutter door, and then the bolts are passed through the mounting groove 18 and the holes on the rolling shutter door and fixed with nuts.

[0044] Embodiment 2:

[0045] A rolling shutter door guide groove structure, this embodiment makes the following improvements on the basis of embodiment 1, such as Figure 1 and Figure 5 As shown:

[0046] The top of the guide frame 1 is rotatably connected to a fifth shaft 21 , and the outer wall of the fifth shaft 21 is fixedly connected to an arc-shaped guide plate 19 .

[0047] The guide frame 1 has a receiving groove 20 at the top, and a second torsion spring 22 is fixedly connected to the inner wall of the receiving groove 20 , and the other end of the second torsion spring 22 is fixedly connected to the outer wall of the fifth shaft 21 .

[0048] Figure 1 The figure shows the initial state of the arc guide plate 19. The rolling shutter door is installed at the top of the door opening or other required installation positions. When the rolling shutter door is installed, the whole is in the retracted state. At this time, the arc guide plate 19 is rotated to open it outward, and the torsion spring 22 is elastically deformed under the force. At this time, the bottom edge of the rolling shutter door can smoothly enter the guide frame 1, and then the rolling shutter door is unrolled downward until it reaches the support frame 2. Then the arc guide plate 19 is released, and the torsion spring 22 provides a rotational torque, so that the arc guide plate 19 contacts the rolling shutter door to provide guidance for the rolling shutter door.

[0049] The device provides an arc guide plate 19 and a torsion spring 22, and utilizes the shape characteristics of the arc guide plate 19 itself to provide guidance for the rolling shutter door. The arc surface setting can avoid jamming between the arc guide plate 19 and the rolling shutter door, thereby ensuring that the rolling shutter door can operate reliably.

[0050] Working principle: First, install the guide frame 1 on both sides of the wall or door opening according to the needs. When the rolling shutter door is installed, it is in a retracted state as a whole. Install it on the top of the door opening or other required installation position. At this time, rotate the arc guide plate 19 to open it outward. The torsion spring 22 is elastically deformed under the force. At this time, the bottom edge of the rolling shutter door can smoothly enter the guide frame 1, and then unwind the rolling shutter door until it reaches the support frame 2 and passes through between the two mounting plates 17. At this time, the arc guide plate 19 can be loosened, and the torsion spring 22 provides a rotational torque, so that the arc guide plate 19 contacts the rolling shutter door to provide guidance for the rolling shutter door. Then align the installation groove 18 position and drill on the rolling shutter door. The hole has the same diameter as the mounting groove 18, and then the bolt is passed through the mounting groove 18 and the hole on the rolling shutter door, and fixed with a nut, thereby completing the installation steps of the rolling shutter door and the present device; when the rolling shutter door is in use, it will roll up and down along the inner wall of the guide frame 1 with the roller 11, which will cause wear of the roller 11 for a long time. When the roller 11 is worn and its diameter becomes smaller, the torsion spring 14 provides a rotational force for the sleeve 13, so that the threaded rod 12 moves longitudinally, thereby cooperating with the connecting block 9 to drive the connecting rod 7 and the connecting frame 5 to open outward, driving the roller 11 to contact the inner wall of the guide frame 1, and compensating for the wear of the roller 11, ensuring that the roller 11 is always in reliable contact with the inner wall of the guide frame 1.

[0051] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
