[0035] Embodiment 1:

[0036] Please refer to Figure 1-Figure 3 The present embodiment discloses a fixing structure of a flexible gate door cloth 10, comprising: a rubber column 1 arranged at the end of the door cloth 10; a profile 2, a flattening groove 3 is opened on the profile 2, and the opening direction of the flattening groove 3 is along the length direction of the profile 2, the rubber column 1 is arranged in the flattening groove 3, and there is an accommodating gap 4 for accommodating the door cloth 10 between the flattening groove 3 and the rubber column 1; a countersunk bolt 5, the countersunk bolt 5 is passed through the rubber column 1, and the countersunk bolt 5 is used to squeeze the accommodating gap 4.

[0037] In this embodiment, the rubber column 1 is used to connect the door cloth 10 and the profile 2 of the flexible door. The rubber column 1 cooperates with the flexible door cloth 10 to smoothly feed the door cloth 10 into the flattening groove 3 pre-opened on the profile 2. The flattening groove 3 is used to accommodate and position the rubber column 1 covered by the door cloth 10. The gap between the rubber column 1 and the flattening groove 3 can effectively prevent the installed door cloth 10 from wrinkling, which is convenient for stress concentration caused by wrinkles during subsequent use, thereby effectively avoiding damage to the door cloth 10 and improving the service life of the door cloth 10. The countersunk bolt 5 is used to penetrate the rubber column 1, and the central axis of the countersunk bolt 5 coincides with the central axis of the rubber column 1 after installation, so that after the countersunk bolt 5 penetrates the rubber column 1, the rubber column 1 expands, so that the rubber column 1 abuts against the inner wall of the flattening groove 3, thereby fixing the rubber column 1 and the door cloth 10 inside the flattening groove 3, improving its stability during use.

[0038] It should be noted that the rubber column 1 is made of rubber material, which is a highly elastic polymer material with reversible deformation. It is elastic at room temperature and can produce a large deformation under a small external force, and can return to its original shape after the external force is removed. The excellent performance of rubber facilitates the installation and removal of the door cloth 10 and the reuse of the rubber column 1.

[0039] Please refer to Figure 1-Figure 3 In some implementations of the present embodiment, an expansion collar 6 is provided between the door cloth 10 and the profile 2 , and the outer side wall of the expansion collar 6 abuts against the inner side wall of the flattening groove 3 .

[0040] In this embodiment, the expansion collar 6 is used to fill the accommodation gap 4 between the door cloth 10 and the profile 2 to avoid direct contact between the door cloth 10 and the profile 2 and to avoid damage by the profile 2 during lifting and lowering.

[0041] Please refer to Figure 1-Figure 3 In some implementations of the present embodiment, a receiving groove 7 is provided at the end of the rubber column 1 , and the head of the countersunk bolt 5 is located in the receiving groove 7 .

[0042] In this embodiment, the above-mentioned receiving groove 7 is used to accommodate the countersunk bolt 5. When the countersunk bolt 5 is inserted into the rubber column 1, the tail of the countersunk bolt 5 enters the interior of the rubber column 1, and the head of the countersunk bolt 5 is located in the receiving groove 7, so as to prevent the head of the countersunk bolt 5 from protruding out of the rubber head, prevent the countersunk bolt 5 from loosening or damage when the vertical driving profile 2 slides, prevent the door cloth 10 from loosening or falling off, and improve the stability of the fixation of the door cloth 10.

[0043] Please refer to Figure 1-Figure 3 In some implementations of the present embodiment, a guide hole 8 for accommodating the tail of the countersunk bolt 5 is opened on the rubber column 1, and the central axis of the guide hole 8 coincides with the central axis of the countersunk bolt 5.

[0044] In this embodiment, the guide hole 8 is used to guide the tail of the countersunk bolt 5 to prevent the countersunk bolt 5 from piercing the door cloth 10 attached to the outer wall of the rubber column 1 due to its tilted direction when entering the rubber column 1, thereby improving the stability during installation and reducing the technical requirements for the operating staff.

[0045] Please refer to Figure 1-Figure 3 In some implementations of this embodiment, the mouth of the flattening groove 3 is provided with an arc chamfer structure 9.

[0046] In this embodiment, the arc chamfered structure 9 can eliminate the sharp angles of the corners, making the transition smoother, thereby reducing stress concentration, avoiding damage to the door cloth 10 caused by the corners during use and installation, and improving the service life of the door cloth 10.

[0047] When in use, the rubber column 1 is passed through the preset positioning ring 11 at the end of the door cloth 10, and the rubber column 1 and the positioning ring 11 of the door cloth 10 are pushed into the flattening groove 3 together. When the two ends of the rubber column 1 are flush with the two ends of the profile 2, stop, and then push the expansion ring 6 from the end into between the flattening groove 3 and the door cloth 10. Finally, align the countersunk screw with the guide hole 8, screw the countersunk screw into the rubber head, and when the head of the countersunk screw abuts against the rubber column 1, it is ready.

[0048] Embodiment 2:

[0049] Please refer to Figure 4This embodiment provides a flexible door, including a fixing structure of a flexible door cloth 10 and the door cloth 10 , a positioning ring 11 is provided at the end of the door cloth 10 , and the positioning ring 11 is located in the accommodating gap 4 .

[0050] In this embodiment, the door cloth 10 is a flexible structure, and the positioning ring 11 is located at the upper and lower sides of the door cloth 10. The positioning ring 11 can be formed by bending, sewing or hinged, which is convenient for the subsequent positioning and fixing of the rubber column 1, and improves the convenience and stability of installation. The fixed structure of the flexible door cloth 10 and the flexible door formed by the door cloth 10 can effectively avoid the door cloth 10 from forming wrinkles during installation, improve its tensile strength, and increase its service life.

[0051] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
