Description

Technical Field

[0001] This invention belongs to the field of push-screen door technology, and particularly relates to a new type of large-span (≤6.0 meters) and height (≤4.0 meters) roller shutter screen door that is easy to assemble and disassemble. Background Technology

[0002] Roller screen doors are widely used in the construction industry due to their beautiful appearance, convenient opening and closing, and space-saving features. However, most existing roller screen doors are one-piece structures, which have drawbacks such as the inability to replace the roller shutter and difficulty in installation. In particular, during long-term use, the roller shutter will accumulate a lot of dust, bacteria, mites, or become damaged. At this time, if the roller screen or roller blind cannot be replaced with a new roller shutter, it can only be discarded, which cannot meet the needs of customers. Summary of the Invention

[0003] This invention provides a novel roller shutter screen door that is easy to assemble and disassemble, thereby solving the technical problems of existing roller shutter screen doors where the roller shutter cannot be replaced and installation is difficult.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a novel roller shutter screen door that is easy to assemble and disassemble, comprising a window frame and a roller shutter box installed on one side of the window frame. The roller shutter box has a curtain assembly that can be unfolded or rolled up. The upper and lower parts of the window frame are provided with tracks for the movement of the curtain assembly. The curtain assembly includes a pivot, a curtain, and a pull-out part that is slidably disposed in the track. One end of the curtain is wrapped around the pivot, and the other end extends out of the roller shutter box through a slot opened on the roller shutter box and is detachably connected to the pull-out part. The roller shutter box includes a bottom box and an outer cover that is fastened to the bottom box. The pivot is rotatably disposed in the bottom box. A locking mechanism for assembling and disassembling the pivot is provided on one side of the bottom box. One end of the pivot is provided with a locking part that matches the locking mechanism.

[0005] Furthermore, the locking mechanism includes a fixed block and an adjusting tension mechanism. The fixed block is movably provided with a transmission gear and a screw that meshes with the transmission gear. The screw is rotatably disposed in a movable groove on one side of the fixed block. The fixed block is provided with a first groove, and the transmission gear is provided with a second groove corresponding to the first groove. The engaging part at one end of the rotating shaft is detachably disposed in the second groove through the first groove.

[0006] Furthermore, the tension adjustment mechanism includes a locking block and a locking screw. The locking block has a connecting end that matches the first slot. The locking block is detachably set in the first slot through the connecting end. The locking block has a first fixing hole that corresponds to the movable slot. The outer cover has a second fixing hole that corresponds to the first fixing hole. The locking screw is connected to the screw drive through the first fixing hole and the second fixing hole.

[0007] Furthermore, the bottom box is provided with blocks at both ends, the blocks are flush with the window frame, the fixing block is fixed on one side of the block, and the other side of the block is provided with a rotating hole for the rotating shaft to rotate.

[0008] Furthermore, the fixed block has a circular toothed hole, the transmission gear is rotatably disposed in the toothed hole, the toothed hole is connected to the movable groove, and the screw drives the transmission gear to rotate.

[0009] Furthermore, the track is detachably installed inside the window frame, and the track is provided with a first movable position and a second movable position. The pull-out part is provided with a positioning block and a pulley, and the positioning block and the pulley are respectively movably installed in the first fixing hole and the second fixing hole.

[0010] Furthermore, the track is fixed to the inside of the window frame by fixing bolts.

[0011] Furthermore, the window frame includes an upper frame, a lower frame, and a bottom frame, which together with the roller shutter box form a square window frame.

[0012] Furthermore, the pull-out part is provided with a handle to facilitate the movement of the pull-out part.

[0013] By using the above technical solution, compared with the prior art, the present invention has the following beneficial effects: By detachably setting the rotating shaft in the roller shutter box by fixing it with a locking mechanism, specifically, when the rotating shaft needs to be disassembled, first unscrew the locking screw on the outer cover. Since one end of the locking screw is connected to the screw drive, when the locking screw is rotated, it will drive the screw to rotate. Then the rotating screw will drive the transmission gear meshing with it to rotate, so that the second groove on the transmission gear and the first groove on the fixing block are aligned in the same direction, thereby forming a groove for the engaging part of one end of the rotating shaft to pass through. At this time, the locking screw can be removed. After removing the locking screw, the outer cover, the locking block and the rotating shaft can be removed in sequence. The above disassembly and assembly method not only makes the rotating shaft more stably installed in the roller shutter box and has a simple structure, but also makes it easier to disassemble and install, thereby solving the technical problems of existing roller shutter screen doors that cannot replace the roller shutter and are difficult to install.

[0025] The first embodiment of the present invention, as follows: Figure 1-4 As shown: A novel roller shutter screen door that is easy to assemble and disassemble includes a window frame 1 and a roller shutter box 2 installed on one side of the window frame 1. The roller shutter box 2 has a curtain assembly that can be unfolded or rolled up. The upper and lower parts of the window frame 1 are provided with tracks 101 for the curtain assembly to move. The curtain assembly includes a pivot 3, a curtain 4, and a pull-out part 5 that is slidably arranged in the track 101. One end of the curtain 4 is wrapped around the pivot 3, and the other end extends out of the roller shutter box 2 through a slot opened on the roller shutter box 2 and is detachably connected to the pull-out part 5. The roller shutter box 2 includes a bottom box 201 and an outer cover 202 that is fastened to the bottom box 201. The pivot 3 is rotatably arranged in the bottom box 201. A locking mechanism for assembling and disassembling the pivot 3 is provided on one side of the bottom box 201. One end of the pivot 3 is provided with a locking part 301 that matches the locking mechanism. The locking part 301 is integrally formed on the locking part 301.

[0026] like Figure 2-3 As shown: The locking mechanism includes a fixed block 6 and an adjusting tension mechanism. A transmission gear 601 and a screw 602 meshing with the transmission gear 601 are movably arranged in the fixed block 6. The screw 602 is rotatably arranged in a movable groove 603 on one side of the fixed block 6. The fixed block 6 is provided with a first groove 604. The transmission gear 601 is provided with a second groove 605 corresponding to the first groove 604. The engaging part 301 at one end of the rotating shaft 3 is detachably arranged in the second groove 605 through the first groove 604.

[0027] like Figure 3 As shown: The tension adjustment mechanism includes a locking block 7 and a locking screw 8. The locking block 7 has a connecting end 701 that matches the first slot 604. The locking block 7 is detachably mounted in the first slot 604 through the connecting end 701. The locking block 7 has a first fixing hole 702 corresponding to the movable slot 603. The outer cover 202 has a second fixing hole 203 corresponding to the first fixing hole 702. The locking screw 8 is connected to the screw 602 through the first fixing hole 702 and the second fixing hole 203. The connecting end 701 of the locking block 7 engages with the first slot 604, and the locking block 7 is also connected to the fixing block 6 through the locking screw 8.

[0028] By detachably mounting the rotating shaft 3 inside the roller shutter box 2 with a locking mechanism, specifically, when the rotating shaft 3 needs to be disassembled, first unscrew the locking screw 8 on the outer cover. Since one end of the locking screw 8 is connected to the screw rod 602, rotating the locking screw 8 will drive the screw rod 602 to rotate. Then, the rotating screw rod 602 will drive the transmission gear 601 that meshes with it to rotate, so that the second slot 605 on the transmission gear 601 and the first slot 604 on the fixing block 6 are aligned in the same direction, thereby forming a slot for the engaging part 301 at one end of the rotating shaft 3 to pass through. At this time, the locking screw 602 can be removed. After removing the locking screw 602, the outer cover 202, the locking block 7, and the rotating shaft 3 can be removed in sequence. The above disassembly and assembly method not only makes the rotating shaft more stably installed in the roller shutter box and has a simple structure, but also makes it easier to disassemble and install, thereby solving the technical problems of existing roller shutter screen doors that cannot replace the roller shutter and are difficult to install.

[0029] like Figure 2 As shown: The bottom box 201 has stop blocks 204 at both ends, which are flush with the window frame 1. A fixing block 6 is fixed to one side of the stop block 204, and the other side of the stop block 204 has a rotating hole for the rotating shaft 3 to rotate. The stop blocks 204 are fixed to both ends of the bottom box 201 by threaded connection, serving to protect and seal the bottom box 201. The fixing block 6 is also fixed to one side of the stop block 204 by threaded connection. The rotating parts on both sides of the rotating shaft 3 are located within the rotating hole and the transmission gear 601 of the fixing block 6, thus allowing the rotating shaft 3 to rotate within the bottom box 201.

[0030] like Figure 3 As shown: A circular toothed hole 606 is provided on the fixed block 6, and the transmission gear 601 is rotatably disposed in the toothed hole 606. The toothed hole 606 is connected to the movable groove 603, and the screw 602 drives the transmission gear 601 to rotate.

[0031] like Figure 4 As shown: The track 101 is detachably installed inside the window frame 1. The track 101 is provided with a first movable position 105 and a second movable position 106. The pull-out part 5 is provided with a positioning block 501 and a pulley 502. The positioning block 501 and the pulley 502 are respectively movably installed in the first fixing hole 702 and the second fixing hole 203.

[0032] like Figure 4 As shown: Track 101 is fixed to the inside of window frame 1 by fixing bolt 9.

[0033] By fixing the track 101 to the inside of the window frame 1 with a threaded connection, it is easy to replace and the overall strength is increased. The positioning block 501 and the pulley 502 make it easier for the pull-out part 5 to move within the track 101.
