Description

Technical Field

[0001] This application relates to the field of sliding door technology, and in particular to a windproof mechanism and a sliding door. Background Technology

[0002] Sliding doors, also known as electric sliding doors, automatic sliding doors, intelligent sliding doors, or push-pull doors, are door structures that open and close by moving the door panels in parallel linear directions, either in the same or different directions. Currently, common electric sliding door structures include those with and without guide rails. In a sliding door with guide rails, the drive motor is fixed to one side of the passageway, which is then fitted with guide rails. The lower part of the door body has a rack that meshes with the drive motor's gears and rollers that roll along the guide rails. The drive motor rotates the transmission gears, causing the door body to move left and right along the guide rails, thus opening and closing the door.

[0003] In the existing technology, ordinary windproof components cannot fit well with the structure of the door, making the door susceptible to interference from wind or uneven road surfaces when moving, resulting in severe left and right swaying of the door. Utility Model Content

[0027] Figure 1 - Figure 6An embodiment of the windproof mechanism of this application is shown, including a fixing member 1, which is used to connect the upright of the sliding door (not shown in the figure). A bearing 2 is provided inside the fixing member 1, and a windproof wheel 3 is connected to the bearing 2. The windproof wheel 3 includes a connecting shaft 31 and a windproof component 32. The windproof component 32 includes a first connecting part 321, a second connecting part 322 and a third connecting part 323 connected in sequence. The surface of the first connecting part 321 is arc-shaped and is adapted to the slide groove 101 of the upper slide rail 10 of the sliding door. The size of the second connecting part 322 is smaller than that of the first connecting part 321 and the third connecting part 323. The size of the first connecting part 321 is smaller than that of the third connecting part 323. The first connecting part 321 and the third connecting part 323 are sandwiched at the protrusion 102 on the upper side of the slide groove 101. The protrusion 102 corresponds to the second connecting part 322.

[0028] In this application, the windproof component 32 is composed of a first connecting part 321, a smaller second connecting part 322, and a larger third connecting part 323 connected in sequence. This design not only makes the windproof mechanism compact and reduces the space occupied, but also enhances the fit with the slide groove 101 and the protrusion 102 through the size change, effectively enhancing the stability of the sliding door under wind pressure, reducing the risk of shaking or accidental opening caused by wind, and improving the overall windproof effect.

[0029] In some embodiments, the fixing member 1 includes a first sealing cavity 11 and a second sealing cavity 12. Bearings 2 are provided in both the first sealing cavity 11 and the second sealing cavity 12. The bearings 2 connect to the upper part of the connecting shaft 31, and the lower end of the connecting shaft 31 connects to the windproof member 32. In this application, the connecting shaft 31 of the windproof wheel 3 is connected to the bearings 2, which ensures the stability of the windproof wheel 3's rotation and the stability and smoothness of the sliding door's movement.

[0030] In some embodiments, the upper end of the fastener 1 is sealed to prevent rainwater from entering the fastener 1.

[0031] In some embodiments, a pair of bearings 2 are provided in both the first sealing cavity 11 and the second sealing cavity 12, with the pair of bearings 2 stacked vertically, and the upper end of the connecting shaft 31 extending out from the upper side of the bearing 2. This can prevent the windproof wheel 3 from tilting to the side, further improving the stability and smoothness of the sliding door's movement.

[0032] In some embodiments, spaced-apart limiting protrusions 13 extend from the inner walls of the first sealing cavity 11 and the second sealing cavity 12, and the bearing 2 is disposed between the limiting protrusions 13. The limiting protrusions 13 are used to support and limit the bearing 2, preventing movement of the bearing 2 and ensuring the stability of the rotation of the windproof wheel 3.

[0033] In some embodiments, the cross-sections of the first sealing cavity 11 and the second sealing cavity 12 are arc-shaped. This allows them to be adapted to the shape of the bearing 2, thus providing better positioning of the bearing 2.

[0034] In some embodiments, the lower ends of both the first sealing cavity 11 and the second sealing cavity 12 are provided with mounting ports 14, which are used to install the connecting shaft 31. The windproof wheel 3 can be easily removed from the mounting port 14 for maintenance.

[0035] In some embodiments, the fixing member 1 further includes a third sealing cavity 15, which is located between the first sealing cavity 11 and the second sealing cavity 12. A connector 5 is disposed in the third sealing cavity 15 for connecting the column. The connector 5 can be a bolt or similar structure. By connecting the column of the sliding door through the connector 5, the firmness of fixing the fixing member 1 can be improved.

[0036] In some embodiments, fixing portions 16 extend outward from both sides of the fixing member 1, and the fixing portions 16 are used to connect to the column. This ensures that the fixing member 1 can be firmly connected to the column.

[0037] In some embodiments, a reinforcing member 4 is provided at the center of the outer side of the fastener 1. The outer side of the reinforcing member 4 has a square structure, and the inner side of the reinforcing member 4 corresponds to the third sealing cavity 15. This can improve the structural strength of the fastener 1.

[0038] This application also provides a sliding door, including the aforementioned windproof mechanism.

[0039] Therefore, this application discloses a windproof mechanism. The windproof component is composed of a first connecting part, a smaller second connecting part, and a larger third connecting part connected in sequence. This design not only makes the windproof mechanism compact and reduces the space occupied, but also enhances the fit between the windproof component and the slide and protrusion through size changes. This effectively enhances the stability of the sliding door under wind pressure, reduces the risk of shaking or accidental opening caused by wind, and improves the overall windproof effect.

[0040] The above are merely embodiments of this application and do not limit the scope of this patent application. Any equivalent structural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the scope of patent protection of this application.
