Description

Technical Field

[0001] This utility model relates to the field of roller shutter technology, and in particular to a wind-resistant roller shutter. Background Technology

[0002] Roller shutters are a common type of door. In areas or seasons with strong winds, traditional roller shutters are affected by wind pressure, causing the door panels to sway or even derail. This not only affects the normal use of the roller shutter, but may also pose safety hazards to the surrounding environment and people in severe cases.

[0003] To address these issues, existing technologies typically improve the door panel's wind pressure resistance by increasing its thickness or using more robust materials, or by adding additional reinforcing structures to enhance its overall stability. However, this results in a bulky structure and high installation and maintenance costs. On the other hand, the door panel and guide rail are often connected by snap-fit ​​fasteners. While this connection method can ensure the normal operation of the door panel under normal conditions, it is prone to significant deformation under strong winds. This can cause the snap-fit ​​fasteners to fail, resulting in the door panel coming off the guide rail groove.

[0004] Therefore, it is necessary to propose a wind-resistant roller shutter door to overcome the shortcomings of existing technologies. Utility Model Content

[0005] The purpose of this utility model is to overcome the above-mentioned technical deficiencies and propose a wind-resistant roller shutter door to solve the problems mentioned in the background art.

[0006] To achieve the above technical objectives, the present invention provides a wind-resistant roller shutter door, comprising: a door track and several door panels, the door panels being hinged end-to-end from top to bottom, with a hanging piece at the upper end connected to a lifting drum and a bottom beam at the lower end; wind-resistant rods are provided at the hinge points of two door panels, and wind-resistant wheels are provided at the ends of the wind-resistant rods; the door track includes a front door track and a rear door track, a wind-resistant baffle is provided on the rear door track, the front door track is fastened to the rear door track, and the wind-resistant wheels are confined within the space enclosed by the wind-resistant baffle, the side of the rear door track, and the front door track.

[0007] Furthermore, the upper and lower ends of the door panel are respectively provided with a pivot part and a hook-shaped receiving cavity. The pivot parts on two adjacent door panels are kept within the hook-shaped receiving cavity and can rotate freely. The left and right sides of the door panel are provided with end caps, which hold the pivot parts within the hook-shaped receiving cavities. The wind-resistant rod passes through the end caps and is inserted into the pivot part.

[0008] Furthermore, the end cap includes a support plate, with a limiting part and a covering part respectively provided at both ends of the support plate. The support plate is provided with bolt holes, and the left and right ends of the door panel are provided with bolt seats that mate with the bolt holes. The limiting part closes one end of the hook-shaped receiving cavity, and the covering part is held above it. Both parts are provided with through holes that are compatible with the wind-resistant rod.

[0009] Furthermore, the end of the wind-resistant rod inserted into the end cap has a D-shaped cross section, the pivot part is provided with a D-shaped mounting hole adapted to the wind-resistant rod, the wind-resistant wheel is a V-shaped grooved wheel, and the groove of the wind-resistant wheel engages with the wind-resistant barrier.

[0010] Furthermore, the inner wall of the hook-shaped accommodating cavity is provided with several sound-absorbing hair strip slots, and the sound-absorbing hair strips in the sound-absorbing hair strip slots abut against the pivot part.

[0011] Compared with the prior art, the beneficial effects of this utility model include:

[0012] 1. This utility model significantly improves the wind resistance of roller shutter doors by adding wind-resistant bars and wind-resistant wheels to the traditional roller shutter door design, and confining the wind-resistant wheels within the space enclosed by a specially designed wind-resistant baffle and the door track. Under strong winds, even if the door panel bends under pressure, the wind-resistant wheels will be restrained by the wind-resistant baffle and will not detach from the door track, thus effectively preventing the door panel from being damaged or detached due to wind pressure, and ensuring the stability and safety of the roller shutter door.

[0013] 2. This utility model achieves hinged connection between door panels by setting a pivot part and a hook-shaped receiving cavity, and sets a sound-absorbing strip slot on the inner wall of the hook-shaped receiving cavity. The sound-absorbing strip is pressed against the pivot part, which effectively reduces the noise when the door panel is raised and lowered. At the same time, the wind-resistant rod and the pivot part adopt a D-shaped cross-section design, which avoids the relative rotation between the wind-resistant rod and the profile during the opening and closing of the door, reduces the wear on the profile, and thus extends the service life of the roller shutter door.

It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0020] Reference Figure 1 This utility model provides a wind-resistant roller shutter door, including a door track 4 and several door panels 2. The several door panels 2 are hinged from top to bottom to form a continuous door structure. The upper end of the door structure is provided with a hanging plate 1 connected to a lifting drum. The roller shutter door can be opened and closed by the winding and releasing of the lifting drum. The lower end of the door panel 2 is provided with a bottom beam 3 to increase the rigidity and stability of the door panel. A wind-resistant rod 5 is provided at the hinge of two door panels 2. A wind-resistant wheel 6 is provided at the end of the wind-resistant rod 5. The wind-resistant wheel 6 is always kept within the door track 4 to achieve the wind-resistant function.

[0021] Reference Figure 2 , Figure 3 The door track 4 includes a front door track 401 and a rear door track 402, with a windproof baffle 403 installed on the rear door track 402. The front door track 401 is fastened to the rear door track 402 to form a closed track structure. The windproof wheel 6 is a V-shaped grooved wheel, whose groove engages with the windproof baffle 403. One end of the wheel is confined within the space enclosed by the windproof baffle 403, the side of the rear door track 402, and the front door track 401. In this way, even if the door panel is bent under the force of strong wind, the windproof wheel 6 will be restricted by the windproof baffle 403 and will not detach from the door track 4, thus ensuring the stability of the roller shutter door.

[0022] Reference Figure 4 , Figure 5 The upper and lower ends of the door panel 2 are respectively provided with a pivot part 201 and a hook-shaped receiving cavity 202; the pivot parts 201 on two adjacent door panels 2 are kept within the hook-shaped receiving cavity 202 and can rotate freely, realizing the hinged connection between the door panels 2. Several sound-absorbing strip slots 205 are also provided on the inner wall of the hook-shaped receiving cavity 202. The sound-absorbing strips in the sound-absorbing strip slots 205 are pressed against the pivot part 201, which not only reduces the noise when the door panel is raised and lowered, but also plays a certain role in buffering and protecting the pivot part 201, thus extending the service life of the roller shutter door.

[0023] The door panel 2 has end caps 7 on both sides. Each end cap 7 includes a support plate 701. The support plate 701 has a limiting part 702 and a covering part 703 at both ends. The support plate 701 has bolt holes 705. The door panel 2 has bolt seats 703 at both ends that mate with the bolt holes 705. The end caps 7 are fixed to the door panel by bolts. The limiting part 702 closes one end of the hook-shaped receiving cavity 202, and the covering part 703 remains above it. Both of them have through holes 704 that are adapted to the wind-resistant rod 5. The wind-resistant rod 5 passes through the through holes 704 and connects to the pivot part 201.

[0024] One end of the insertion end cap 7 of the wind-resistant rod 5 has a D-shaped cross section, and the pivot part 201 is provided with a D-shaped mounting hole 204 that matches the wind-resistant rod 5. This D-shaped cross section design can prevent the wind-resistant rod 5 and the profile from rotating relative to each other during the opening and closing of the door, thus avoiding wear on the profile and extending the service life of the roller shutter door.
