DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. 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] See also Figure 1-4 The utility model provides a technical solution for a wind-resistant reinforced rolling shutter door device: a wind-resistant reinforced rolling shutter door device, comprising: a door frame component and a door panel for closing the inner space of the door frame, wherein the door frame is composed of an outer shell 1, a guide rail 2 and a bottom frame 5, the number of the guide rails 2 is two, which are symmetrically installed at the bottom ends of the outer shell 1, and the bottom ends of the guide rails 2 are installed with the bottom frames 5, and the outer walls on the opposite sides of the two guide rails 2 are grooved, and the door panel can slide in the groove to be limited.

[0020] A tubular motor 17 is installed in the inner cavity of the shell 1, and one end of the rotating shaft 16 is installed at the output end of the tubular motor 17, and the other end of the rotating shaft 16 is rotatably installed on the inner wall of the shell 1, and the outer wall of the rotating shaft 16 is rolled up and wrapped with a door panel. Turning on the tubular motor 17 can drive the rotating shaft 16 to rotate, so as to realize the rolling or unfolding of the door panel, wherein the door panel includes: a door curtain 3, the top end of the door curtain 3 is fixedly installed on the rated outer wall of the rotating shaft 16, and the bottom end of the door curtain 3 is installed with a fixing strip 4, the door curtain 3 is an existing common roller curtain, composed of a plurality of strip curtain pieces, and has the functions of shading, dividing space, etc.

[0021] Since most of the door panel is a thin layer of plate material after it is unfolded, it lacks effective support. When the middle part of the door panel is hit by strong wind, it will be deformed or damaged. In order to improve its wind resistance, the following scheme is proposed: windproof support components are respectively arranged on the front and rear sides of the door panel, and the two windproof support components are arranged crosswise with each other. The components can provide support for the door panel body after the door panel is unfolded to prevent the middle part of the door panel from being damaged by strong wind. The windproof support component is a windproof strip 6, one end of which is rotatably installed on the top of the outer wall of the guide rail 2, and the other end of the windproof strip 6 is rotatably installed on the outer wall of the fixed strip 4, and the connection between the windproof strip 6 and the fixed strip 4 is located on the side of the outer wall of the fixed strip 4 away from the connection between the windproof strip 6 and the guide rail 2. In addition, the windproof strip 6 consists of two parts, namely an inner tube and an outer tube. When the door curtain 3 is unfolded, the fixed strip 4 moves downward, thereby causing the windproof strip 6 to rotate and extend. When the fixed strip 4 moves to fit with the bottom frame 5, the windproof strip 6 extends to its longest length and can cover the diagonal of the door curtain 3 diagonally.

[0022] When the fixing strip 4 is fitted with the bottom frame 5, the rolling door can be locked using its own lock. However, the force on the single-point lock is too concentrated, and the lock core is easily pulled by external force to deform and damage the lock tongue and other components. Based on this, the following solution is proposed: a plurality of hook components are installed in the inner cavity of the bottom frame 5, and the hook components are evenly arranged at the connection between the bottom frame 5 and the fixing strip 4 to disperse the force and reduce the force on the rolling door lock.

[0023] The overhanging component includes: a first cavity 7, the first cavity 7 is opened in the inner cavity of the bottom frame 5, a hook 8 is rotatably installed on the inner wall of the first cavity 7, wherein the outer wall of the hook 8 is set in an "L" shape, a second cavity 9 is opened at the bottom end of the fixing strip 4, a fixing rod 10 is installed in the inner cavity of the second cavity 9, the hook 8 can enter the inner cavity of the second cavity 9 after rotation, and hook with the outer wall of the fixing rod 10, a connecting column 11 is installed on the outer wall of the hook 8, one end of a spring 12 is hooked on the outer wall of the connecting column 11, and the other end of the spring 12 is fixedly installed on the inner wall of the first cavity 7, the spring 12 is spirally elastic, and elastic deformation is generated by stretching or extrusion, and the outer The hook 8 returns to its initial state after the force is applied, and the hook 8 is rotated to stretch the spring 12. When the hook 8 is hooked with the fixed rod 10, the hook 8 tilts in the direction of the spring 12 pulling force. The spring 12 is opposite to the reset rotation direction of the hook 8. At this time, the spring 12 pulls the hook 8 to prevent it from resetting so that it is tightly hooked with the fixed rod 10. A lever 13 is also installed on the outer wall of the hook 8. The outer walls of the bottom frame 5 and the fixed bar 4 are respectively provided with a first slide 14 and a second slide 15, and the two are connected. The outer wall of the lever 13 is slidably embedded in the inner cavity of the first slide 14. The staff manually pushes the lever 13 to slide it along the inner cavity of the first slide 14 and the second slide 15 to realize the rotation of the hook 8.

[0024] The detailed connection means are well-known technologies in the art. Through the use of wires, all electrical components in this case are connected to their corresponding power supplies, and appropriate controllers should be selected according to actual conditions to meet control requirements. The specific connection and control sequence should refer to the following working principle, in which the electrical components complete the electrical connection in the order of working. The detailed connection means are well-known technologies in the art. The following mainly introduces the working principle and process, and no longer explains the electrical control.

[0025] When in use, the tubular motor 17 is turned on to rotate the shaft 16, thereby unfolding the door curtain 3. As the door curtain 3 unfolds, the fixing strip 4 begins to descend until the fixing strip 4 fits with the top of the bottom frame 5. During this process, the front and rear windproof strips 6 rotate and extend respectively, providing a certain support force for the door curtain 3, improving the windproof ability and avoiding damage. Subsequently, the lever 13 is rotated respectively to make it slide into the inner cavity of the second slideway 15 along the inner cavity of the first slideway 14, so that the hook 8 rotates, and the hook 8 is transferred into the inner cavity of the second cavity 9 and hooked with the fixing rod 10. During this process, the spring 12 is stretched to ensure that the hook 8 is firmly hooked with the fixing rod 10 under the tension of the spring 12. Using multiple such devices can disperse the force to avoid the rolling door lock being damaged by the force. In actual use, it can not only enhance the windproof performance of the rolling door body to avoid damage caused by strong wind, but also enhance the strength of the door bottom to avoid damage to the door lock caused by strong impact or pulling.
