[0029] Although the existing track-type industrial lifting door can completely hide the hinge, it is relatively complex and has a high manufacturing cost, which is not conducive to production.
[0030] Depend on Figure 1-6The utility model provides a track-type industrial lifting door.
[0031] Specifically, by Figure 1-6 A device is provided, comprising a track body 1, a plurality of door panels 2 slidably connected between two track bodies 1, and a connecting component 3 for connecting two adjacent door panels 2, wherein the connecting component 3 comprises a plurality of connecting blocks 301 located in the track body 1 and arranged on both sides of the door panel 2, an annular groove 302 is provided in the middle of the connecting block 301, a C-shaped block 303 is sleeved on the inner wall of the annular groove 302, a plurality of sliding rods 304 are inserted between two adjacent C-shaped blocks 303, limiting blocks 305 are installed at both ends of the sliding rod 304, a limiting groove 306 for the limiting block 305 to slide and limit is provided inside the C-shaped block 303, a tension spring 307 sleeved on the outside of the sliding rod 304 is installed between two adjacent C-shaped blocks 303, and the tension spring 307 in the initial state makes the two adjacent C-shaped blocks 303 approach each other.
[0032] In the utility model, the tension spring 307 in the initial state makes the two adjacent C-shaped blocks 303 approach each other, ensuring that there is no gap between the two adjacent door panels 2 after the bottom of one of the door panels 2 contacts the ground, ensuring the barrier effect of the door panels 2, and in the process of sliding and rising of the door panels 2 in the track body 1, the passing door panels 2 no longer move vertically but move tiltedly because the upper end of the track body 1 is arc-shaped. At this time, the slide bar 304 slides inside the C-shaped block 303 and makes the two adjacent C-shaped blocks 303 move away from each other, and through the coordinated use of the limit block 305 and the limit block 305, the slide bar 304 is not easy to separate from the C-shaped block 303, thereby ensuring that part of the door panel 2 can smoothly pass through the arc-shaped part of the track body 1 after tilting, and utilizing the elastic reset principle of the tension spring 307 to ensure the barrier effect of the subsequent door panel 2 after descending, the structure of the connecting component 3 is simple and completely hidden in the track body 1 and is more beautiful, solving the problem that the existing track-type industrial lifting door can completely hide the hinge, but is more complicated and has a high manufacturing cost and is not conducive to production.

[0046] The tension spring 307 in the initial state makes the two adjacent C-shaped blocks 303 approach each other, ensuring that there is no gap between the two adjacent door panels 2 after the bottom of one of the door panels 2 contacts the ground, thereby ensuring the barrier effect of the door panels 2. In the process of sliding and rising of the door panels 2 in the track body 1, the passing door panels 2 no longer move vertically but move tiltedly because the upper end of the track body 1 is arc-shaped. At this time, the slide bar 304 slides inside the C-shaped block 303 and makes the two adjacent C-shaped blocks 303 move away from each other, and through the coordinated use of the limit block 305 and the limit block 305, the slide bar 304 is not easy to separate from the C-shaped block 303, thereby ensuring that part of the door panel 2 can smoothly pass through the arc-shaped part of the track body 1 after tilting, and utilizing the elastic reset principle of the tension spring 307 to ensure the barrier effect of the subsequent door panel 2 after descending. The structure of the connecting component 3 is simple and completely hidden in the track body 1, which is more beautiful, thereby solving the problem that the existing track-type industrial lifting door can completely hide the hinge, but is more complicated and has a high manufacturing cost, which is not conducive to production.
[0047] By setting the screw rod 5 and the threaded groove and rotating the connecting block 301, the connecting block 301 can be easily removed or installed from the door panel 2 after the door panel 2 is away from the track body 1. By setting the elastic gasket 6, the pressure between the connecting block 301 and the door panel 2 is reduced, and the connecting block 301 can be prevented from loosening after being tightened on the door panel 2. By setting the hemisphere 7, the friction between the connecting block 301 and the inner wall of the door panel 2 is reduced, ensuring that the door panel 2 moves more smoothly during the movement of the track body 1. The hemisphere 7, the tension spring 307, the slide bar 304, the C-shaped block 303 and the connecting block 301 made of stainless steel are not easy to be corroded and damaged, thereby extending the service life of the hemisphere 7, the tension spring 307, the slide bar 304, the C-shaped block 303 and the connecting block 301.
