DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.

[0027] See also Figure 1-6The utility model provides a quick stacking door which is convenient for replacing door curtains, comprising a door frame 1, wherein a plurality of door curtains 2 are movably arranged in the door frame 1, the top door curtain 2 is fixed to the bottom of the door frame 1 by screws, a counterweight rod 3 is installed under the bottom door curtain 2 by a first connecting mechanism, a wind-resistant rod 4 is arranged between two adjacent door curtains 2, and the wind-resistant rod 4 is connected to the door curtain 2 by a first connecting mechanism.

[0028] See also Figure 1 The counterweight rod 3 can drive the door curtain 2 to descend to close the stacking door. By pulling the counterweight rod 3 up, the door curtain 2 can be driven to fold, thereby opening the stacking door. The role of the wind-resistant rod 4 is to provide wind-resistant performance for the door curtain 2. In this embodiment, a first connecting mechanism is provided between the wind-resistant rod 4 and the door curtain 2 to facilitate the disassembly of the single-piece door curtain 2.

[0029] The first connecting mechanism includes a groove 12, a connecting seat 13, a limiting groove 14 and a limiting protrusion 15. The door curtain 2 is bonded to the inside of the connecting seat 13 by colloid. The connecting seat 13 is slidably arranged inside the groove 12. The limiting protrusion 15 is arranged on the side of the connecting seat 13. The limiting groove 14 is arranged on the inner wall of the groove 12. The limiting protrusion 15 is slidably arranged inside the limiting groove 14. A groove 16 is provided on the surface of the door curtain 2. A reinforcing protrusion 17 is integrally formed on the inner wall of the connecting seat 13. The reinforcing protrusion 17 is engaged with the inside of the groove 16. The reinforcing protrusion 17 is bonded to the groove 16 by colloid.

[0030] See also Figure 2 When removing the door curtain 2, due to the limitation of the counterweight rod 3, the door curtain 2 is always in the door frame 1, and the door frame 1 will hinder the disassembly of the door curtain 2. Therefore, it is necessary to separate the counterweight rod 3 from the door frame 1 first, and then the connecting seat 13 can be separated from the inside of the groove 12 by pulling the connecting seat 13 horizontally. At the same time, the limiting protrusion 15 will also be detached from the inside of the limiting groove 14. At this time, the door curtain 2 can be replaced. After replacing the new door curtain 2, the connecting seat 13 needs to be re-bonded at both ends. In the vertical direction, the limiting protrusion 15 and the limiting groove 14 can limit the door curtain 2 to prevent the door curtain 2 from detaching from the wind-resistant rod 4.

[0031] It should be noted that the provision of the reinforcing protrusions 17 and the grooves 16 can increase the contact area between the door curtain 2 and the connecting seat 13 , thereby increasing the amount of colloid used, thereby achieving the purpose of increasing the connection strength between the door curtain 2 and the connecting seat 13 .

[0032] A reduction motor 5 is installed on the surface of the gantry 1, and a driving rod 6 is provided for internal rotation of the gantry 1. The output end of the reduction motor 5 is connected to one end of the driving rod 6, and a winding wheel 7 is installed on the driving rod 6. A connecting block 8 is fixed to one end of the counterweight rod 3, and a lifting rod 9 is fixed on the surface of the connecting block 8. A wire rope 10 is fixed between the lifting rod 9 and the winding wheel 7. A cover plate 11 is movably provided on the surface of the gantry 1 through a second connecting mechanism, and one side of the cover plate 11 and one side of the gantry 1 are in contact with both sides of the connecting block 8 respectively.

[0033] See also Figure 3 The reduction motor 5 can drive the driving rod 6 to rotate. When the driving rod 6 rotates, it can drive the winding wheel 7 to rotate synchronously. At this time, the winding wheel 7 can wrap the upper end of the wire rope 10 around its surface. At this time, the end of the wire rope 10 will pull the counterweight rod 3 up through the lifting rod 9 and the connecting block 8 to realize the opening of the door curtain 2. When the reduction motor 5 is reversed, the door curtain 2 will be closed by the gravity of the counterweight rod 3. Therefore, when disassembling the door curtain 2, it is necessary to first separate the wire rope 10 from the lifting rod 9 before the counterweight rod 3 can be removed from the inside of the door frame 1. In this embodiment, a reversible cover plate 11 is provided on the door frame 1 through a second connecting mechanism to facilitate opening the door frame 1 and separating the wire rope 10 from the lifting rod 9.

[0034] Specifically, the second connecting mechanism includes a cavity 18, a through slot 19, a limit block 20, a first connecting arm 21 and a second connecting arm 22. The cavity 18 is arranged inside the door frame 1, the through slot 19 is arranged on the surface of the door frame 1 and is connected to the cavity 18, the limit block 20 is fixed to one end of the first connecting arm 21, the first connecting arm 21 is slidably arranged in the through slot 19 and the cavity 18, one end of the second connecting arm 22 is fixed to the surface of the cover plate 11, and the other end of the second connecting arm 22 is hinged to one end of the first connecting arm 21. A magnet sheet 23 is embedded in the surface of the cover plate 11, and the magnet sheet 23 is adsorbed and fixed to the surface of the door frame 1. A threaded hole 24 is provided on the end face of the lifting rod 9, and a screw 25 is connected to the internal thread of the threaded hole 24. A stop block 26 is fixed to one end of the screw 25. The diameter of the stop block 26 is larger than the diameter of the driving rod 6. A recess 27 is provided on the surface of the lifting rod 9, and the side wall of the recess 27 is chamfered. The wire rope 10 is wound around and fixed in the recess 27.

[0035] See also Figure 4 、 5and 6. First, pull the cover plate 11 vertically on the surface of the door frame 1 so that the magnet sheet 23 is detached from the surface of the door frame 1. The cover plate 11 can drive the first connecting arm 21 to move inside the through groove 19 through the second connecting arm 22, and the first connecting arm 21 can drive the limiting hole to move synchronously inside the cavity 18. When the hinge of the first connecting arm 21 and the second connecting arm 22 is completely exposed, the hinge of the first connecting arm 21 and the second connecting arm 22 can be rotated to realize the flipping of the cover plate 11 on the surface of the door frame 1. At this time, rotate the block 26 so that the block 26 drives the screw 25 to rotate inside the threaded hole 24, so that the screw 25 is detached from the threaded hole 24, and then the block 26 can be separated from the lifting rod 9. At this time, the wire rope 10 can be detached from the inside of the groove 16 to realize the separation of the counterweight rod 3 and the frame.

[0036] It should be noted that a snare is provided at the end of the wire rope 10, which is directly sleeved in the groove 16. The diameter of the snare is greater than or equal to the diameter of the lifting rod 9. When the lifting rod 9 is pulled, only the bottom and side of the snare are engaged in the groove 16. When the snare is separated from the surface of the lifting rod 9, even if the diameter of the snare is equal to the diameter of the lifting rod 9, due to the chamfering treatment of the side wall of the recess 27, the snare can slowly detach from the lifting rod 9 under the operation of the staff.

[0037] The connecting block 8 consists of a circular plate 28, a rotating shaft 29 and a roller 30. Multiple rotating shafts 29 are vertically rotated and arranged between two circular plates 28. The roller 30 is fixed on the rotating shaft 29. One of the circular plates 28 is fixed to the end face of the counterweight rod 3, and the other circular plate 28 is fixed to the end face of the lifting rod 9.

[0038] See also Figure 4 When the counterweight rod 3 rises and falls, it can drive the circular plate 28 to move synchronously inside the frame. At this time, the circular plate 28 can drive the roller 30 to move synchronously through the rotating shaft 29. The roller 30 can generate sliding friction with the frame and the cover plate 11, thereby making the counterweight rod 3 move more smoothly.
