[0023] The technical solutions of the present utility model will be explained and described below with reference to the accompanying drawings. However, the following embodiments are only preferred embodiments of the present utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments in the implementation methods without creative effort are all within the protection scope of the present utility model.
[0024] The following describes in detail, with reference to the accompanying drawings, an embodiment of the present invention: a PVC high-speed rolling shutter door installation mechanism.
[0025] Example 1
[0026] For easier understanding, please refer to Figures 1 to 4 An embodiment of the PVC high-speed rolling shutter door installation mechanism provided by this utility model includes a door frame 1, a door curtain 2 disposed on the inner side of the door frame 1, a base plate 3 fixedly connected to the bottom of the door curtain 2, a roller 4 rotatably connected to the top of the door frame 1, one end of the door curtain 2 fixedly connected to the outer wall of the roller 4, an unfoldable limiting component and an installation component disposed between the door frame 1 and the door curtain 2, a drive motor 6 fixedly installed at one end of the door frame 1, a drive gear 7 fixedly installed at one end of the output shaft of the drive motor 6, and a driven gear 5 fixedly installed at one end of the roller 4, the driven gear 5 meshing with the drive gear 7;
[0027] It should be noted that by setting the drive motor 6 to drive the active gear 7 to mesh with the driven gear 5, the roller 4 can be driven to rotate. The rotation of the roller 4 drives the curtain 2 to roll up and unroll.
[0028] The expandable limiting component includes a guard plate 701, a fixing sleeve 702, a U-shaped clip 703, a limiting block 704, a return spring 705, and a first fixing hole 706. The guard plate 701 is rotatably connected to the inner side of the door frame 1. The fixing sleeve 702 is fixedly connected to one side wall of the guard plate 701. The U-shaped clip 703 is slidably connected to the inner side of the fixing sleeve 702. The limiting block 704 is fixedly connected to one outer wall of the U-shaped clip 703. The return spring 705 is sleeved on one outer wall of the U-shaped clip 703. The first fixing hole 706 is opened at one end of the door frame 1. One end of the return spring 705 abuts against one surface of the fixing sleeve 702, and the other end of the return spring 705 abuts against one surface of the limiting block 704. The diameter of the first fixing hole 706 matches the diameter of one end of the U-shaped clip 703, and one end of the U-shaped clip 703 passes through the first fixing hole 706.
[0029] It should be noted that by installing an openable guard plate 701 on one side of the door frame 1, and by using a U-shaped clip 703 on the fixing sleeve 702 to engage with the first fixing hole 706 on the door frame 1, the guard plate 701 can be fixed. When it is necessary to assemble the curtain 2 and the door frame 1, the U-shaped clip 703 can be pulled to cause the limiting block 704 to compress the return spring 705, and one end of the U-shaped clip 703 can be pulled out from the first fixing hole 706 to open the guard plate 701. Then the curtain 2 can be placed directly inside the door frame 1 and the guard plate 701 can be closed. Then the U-shaped clip 703 can be inserted into the first fixing hole 706 again. This facilitates the step-by-step installation of the curtain 2 and the door frame 1, which can improve the problem of the traditional method of installing the door frame 1 first, where it is inconvenient to install the curtain 2 into the door frame 1 due to the height of the door frame 1, and the problem of increasing the weight and inconvenience of installation if the curtain 2 and the door frame 1 are assembled first.
[0030] Example 2
[0031] In some embodiments, such as Figure 1 As shown, the installation assembly includes a pre-embedded rod 801 and a second fixing hole 802. The pre-embedded rod 801 is located on one side of the top of the door frame 1, and the second fixing hole 802 is opened at one end of the pre-embedded rod 801. The diameter of the second fixing hole 802 matches the diameter of one end of the U-shaped clip 703.
[0032] It should be noted that by setting up a pre-embedded rod 801 and opening a second fixing hole 802 on the pre-embedded rod 801 that matches the U-shaped clip 703, during the installation process, the pre-embedded rod 801 is first fixed inside the wall, and then the U-shaped clip 703 at the bottom of the door frame 1 is inserted into the groove opened in the ground, and the U-shaped clip 703 at the top of the door frame 1 is inserted into the second fixing hole 802 on the pre-embedded rod 801, so that the door frame 1 can be directly fixed, thereby further facilitating the quick installation of the PVC roller shutter door.
[0033] In this utility model, the drive motor 6, the driven gear 5, and the driving gear 7 are known components and will not be described in detail here.
[0034] Working principle: When assembling the curtain 2 and the door frame 1, the U-shaped clip 703 can be pulled to compress the return spring 705 by the limit block 704. One end of the U-shaped clip 703 can be pulled out from the first fixing hole 706 to open the guard plate 701. Then, the curtain 2 can be placed directly inside the door frame 1 and the guard plate 701 can be closed. Then, the U-shaped clip 703 can be inserted into the first fixing hole 706 again, which facilitates the step-by-step installation of the curtain 2 and the door frame 1. In addition, during the installation process, the embedded rod 801 is first fixed inside the wall. Then, the U-shaped clip 703 at the bottom of the door frame 1 is inserted into the groove opened in the ground, and the U-shaped clip 703 at the top of the door frame 1 is inserted into the second fixing hole 802 on the embedded rod 801, which can directly fix the door frame 1, thereby further facilitating the quick installation of the PVC roller shutter door.
