It should be noted that the description of these embodiments is used to help understand the present invention, but does not constitute a limitation of the present invention.

[0027] Embodiment 1: This embodiment provides a sealed rolling shutter door, including a door frame 1 and a door head 2. The door frame 1 is rectangular. The door head 2 is fixed to the top of the door frame 1 by welding. A driving mechanism 3 is arranged on the side of the door frame 1. A rolling shutter mechanism 4 is rolled up in the door head 2. The driving mechanism 3 drives the rolling shutter mechanism 4 to roll up. A guide rail mechanism 5 is slidably connected to the door frame 1. A sealing mechanism 6 is arranged on the door frame 1. The sealing mechanism 6 pushes the guide rail mechanism 5 to move toward the side close to the door frame 1. When the rolling shutter door needs to be closed, the driving mechanism 3 drives the rolling shutter mechanism 4 to unfold along the guide rail mechanism 5. When the rolling shutter mechanism 4 is about to be fully unfolded, the rolling shutter mechanism 4 drives the sealing mechanism 6 to move downward. The downward movement of the sealing mechanism 6 drives the guide rail mechanism 5 to move toward the side close to the door frame 1; the rolling shutter mechanism 4 seals the door frame 1, and a better sealing effect is achieved.

[0028] In one embodiment, the driving mechanism 3 includes a driving motor 31, a driving roller 32, a driven roller 33, a belt 34 and a transmission rod 35. The driving motor 31 is fixed to the top side of the door frame 1 by bolts. The driving roller 32 is coaxially welded to the motor shaft of the driving motor 31. The driven roller 33 is rotatably connected to the bottom side of the door frame 1 through a rotating shaft. The belt 34 is wound around the driving roller 32 and the driven roller 33. One end of the transmission rod 35 is fixedly connected to the belt 34 by bolts, and the other end is connected to the rolling curtain mechanism 4.

[0029] Specifically, when it is necessary to retract or deploy the rolling curtain mechanism 4, the driving motor 31 is started. The driving motor 31 drives the driving roller 32 to rotate. The rotation of the driving roller 32 drives the belt 34 to rotate around the driving roller 32 and the driven roller 33. The rotation of the belt 34 drives the transmission rod 35 to move up and down. The up and down movement of the transmission rod 35 drives the rolling curtain mechanism 4 to retract or deploy.

[0030] In this embodiment, the retraction or deployment of the rolling curtain mechanism 4 is realized.

[0031] In one embodiment, the guide rail mechanism 5 includes two guide rails 51, and the two guide rails 51 are respectively connected to the door frame 1.

[0032] Specifically, the two guide rails 51 are of equal size, and the two guide rails 51 are distributed relatively with respect to the door frame 1. The cross-sectional shape of the door frame 1 is "匚"-shaped.

[0033] In this embodiment, the two guide rails 51 provide a movement track for the retraction or deployment of the rolling curtain mechanism 4.

[0034] In one embodiment, the rolling curtain mechanism 4 includes a plurality of rolling curtain sheets 41 and a plurality of traveling wheels 42. The rolling curtain sheets 41 are rectangular plates. The plurality of rolling curtain sheets 41 are rotatably connected along their length directions through hinges. The plurality of traveling wheels 42 are respectively installed in the width direction of the rolling curtain sheets 41, and the traveling wheels 42 roll within the two guide rails 51. The transmission rod 35 is fixed to the outermost one of the plurality of rolling curtain sheets 41 by rivets.

[0035] Specifically, when the rolling curtain mechanism 4 performs a retraction or deployment movement, the traveling wheels 42 move along the extension direction of the guide rails 51, thereby driving the plurality of rolling curtain sheets 41 to retract or deploy.

[0036] In this embodiment, the arrangement of the traveling wheels 42 reduces the resistance during the retraction or deployment movement of the plurality of rolling curtain sheets 41. The arrangement of the plurality of rolling curtain sheets 41 facilitates the winding of the rolling curtain mechanism 4.

[0037] In one embodiment, the door head 2 includes a rolling curtain cylinder 21 and a plurality of sliding components 22. The rolling curtain cylinder 21 is used for winding the plurality of rolling curtain sheets 41. The rolling curtain cylinder 21 is installed at the top end of the door frame 1 through the plurality of sliding components 22.

[0038] Specifically, the shutter roller 21 moves toward or away from the door frame 1 through the sliding assembly 22 .

[0039] In this embodiment, the movement of the roller shutter drum 21 is synchronized with the movement of the guide rail mechanism 5 .

[0040] In one embodiment, the sealing mechanism 6 includes a fixed shell 61, a vertical rod 62, a spring 63, a pressure rod 64, a guide frame 65 and a roller 66. The fixed shell 61 is fixed to the door frame 1 by rivets, the vertical rod 62 is connected to the fixed shell 61 by a spring 63, the spring 63 runs through the vertical rod 62, the pressure rod 64 is fixedly connected to the bottom of the vertical rod 62 by bolts, during the unfolding process of the rolling shutter mechanism 4, the bottom end of the rolling shutter mechanism 4 acts on the pressure rod 64, the guide frame 65 is fixedly connected to the vertical rod 62 by bolts, the roller 66 is installed on the guide rail mechanism 5, the guide frame 65 guides the moving direction of the roller 66, and the roller 66 drives the guide rail mechanism 5 to move toward one side of the door frame 1. The guide frame 65 is an inverted triangle.

[0041] Specifically, when the rolling shutter piece 41 moves downward along the guide rail mechanism 5, the transmission rod 35 presses the pressure rod 64 downward, and the pressure rod 64 drives the vertical rod 62 to move downward. During the downward movement of the vertical rod 62, the spring 63 is compressed, and the guide frame 65 moves downward, so that the roller 66 rolls on the side of the guide frame 65. Since the guide frame 65 is an inverted triangle, as the guide frame 65 moves downward, the roller 66 is pushed toward the side of the door frame 1, thereby realizing the movement of the guide rail mechanism 5 toward the side of the door frame 1.

[0042] In this embodiment, without adding an additional driving source, the guide rail mechanism 5 is moved toward the door frame 1, so that the guide rail mechanism 5 is fitted with the door frame 1, and finally, the whole rolling door is better sealed when closed.

[0043] Embodiment 2: This embodiment provides a sealed rolling shutter door, including a door frame 1 and a door head 2. The door frame 1 is rectangular. The door head 2 is fixed to the top of the door frame 1 by welding. A driving mechanism 3 is arranged on the side of the door frame 1. A rolling shutter mechanism 4 is rolled up in the door head 2. The driving mechanism 3 drives the rolling shutter mechanism 4 to roll up. A guide rail mechanism 5 is slidably connected to the door frame 1. A sealing mechanism 6 is arranged on the door frame 1. The sealing mechanism 6 pushes the guide rail mechanism 5 to move toward the side close to the door frame 1. When the rolling shutter door needs to be closed, the driving mechanism 3 drives the rolling shutter mechanism 4 to unfold along the guide rail mechanism 5. When the rolling shutter mechanism 4 is about to be fully unfolded, the rolling shutter mechanism 4 drives the sealing mechanism 6 to move downward. The downward movement of the sealing mechanism 6 drives the guide rail mechanism 5 to move toward the side close to the door frame 1; the rolling shutter mechanism 4 seals the door frame 1, and a better sealing effect is achieved.

[0044] In one embodiment, the driving mechanism 3 includes a driving motor 31, a driving roller 32, a driven roller 33, a belt 34 and a transmission rod 35. The driving motor 31 is fixed to the top side of the door frame 1 by bolts. The driving roller 32 is coaxially welded to the motor shaft of the driving motor 31. The driven roller 33 is rotatably connected to the bottom side of the door frame 1 through a rotating shaft. The belt 34 is wound around the driving roller 32 and the driven roller 33. One end of the transmission rod 35 is fixedly connected to the belt 34 by bolts, and the other end is connected to the rolling curtain mechanism 4.

[0045] Specifically, when it is necessary to retract or deploy the rolling curtain mechanism 4, the driving motor 31 is started. The driving motor 31 drives the driving roller 32 to rotate. The rotation of the driving roller 32 drives the belt 34 to rotate around the driving roller 32 and the driven roller 33. The rotation of the belt 34 drives the transmission rod 35 to move up and down. The up and down movement of the transmission rod 35 drives the rolling curtain mechanism 4 to retract or deploy.

[0046] In this embodiment, the retraction or deployment of the rolling curtain mechanism 4 is realized.

[0047] In one embodiment, the guide rail mechanism 5 includes two guide rails 51, and the two guide rails 51 are respectively connected to the door frame 1.

[0048] Specifically, the two guide rails 51 are of equal size, and the two guide rails 51 are distributed relatively with respect to the door frame 1. The cross-sectional shape of the door frame 1 is "匚"-shaped.

[0049] In this embodiment, the two guide rails 51 provide a movement track for the retraction or deployment of the rolling curtain mechanism 4.

[0050] In one embodiment, a moving component 7 is arranged between the guide rail mechanism 5 and the door frame 1. The moving component 7 includes a first sliding rail 71 and a first sliding block 72. The first sliding rail 71 is fixed to the door frame 1 by rivets. The first sliding block 72 is fixedly connected to the guide rail mechanism 5 by rivets. The first sliding rail 71 and the first sliding block 72 are in sliding fit.

[0051] Specifically, when an inward force is applied to the guide rail mechanism 5, the first sliding block 72 moves along the extending direction of the first sliding rail 71, thereby realizing the movement of the guide rail mechanism 5 towards one side of the door frame 1.

[0052] In this embodiment, the resistance of the guide rail mechanism 5 moving towards one side of the door frame 1 is reduced, facilitating the movement of the guide rail mechanism 5, and thus achieving the purpose of facilitating the sealing of the rolling curtain mechanism 4.

[0053] In one embodiment, the moving component 7 further includes an elastic member 73. One end of the elastic member 73 is fixed to the door frame 1 by welding, and the other end is fixed to the guide rail mechanism 5 by welding.

[0054] Specifically, the elastic member 73 is a spring. When the guide rail mechanism 5 is not subject to external force, the elastic force of the elastic member 73 is zero.

[0055] In this embodiment, when the elastic member 73 enables the guide rail mechanism 5 to move away from the door frame 1 , this is achieved by relying on the elastic restoring force of the elastic member 73 .

[0056] In one embodiment, the rolling mechanism 4 includes a plurality of rolling pieces 41 and a plurality of running wheels 42. The rolling pieces 41 are rectangular plates. The plurality of rolling pieces 41 are connected by hinges along their lengths. The plurality of running wheels 42 are respectively installed in the width direction of the rolling pieces 41, and the running wheels 42 roll in the two guide rails 51. The transmission rod 35 is fixed to the outermost one of the plurality of rolling pieces 41 by rivets.

[0057] Specifically, when the rolling shutter mechanism 4 performs a retracting or unfolding movement, the running wheel 42 moves along the extension direction of the guide rail 51 , thereby driving the plurality of rolling shutter pieces 41 to be retracted or unfolded.

[0058] In this embodiment, the provision of the running wheels 42 reduces the resistance when the multiple rolling shutter pieces 41 are folded or unfolded. The provision of the multiple rolling shutter pieces 41 facilitates the rolling up of the rolling shutter mechanism 4.

[0059] In one embodiment, the door head 2 includes a shutter roller 21 and a plurality of sliding components 22 . The shutter roller 21 is used to roll up a plurality of shutter sheets 41 . The shutter roller 21 is installed on the top of the door frame 1 through the plurality of sliding components 22 .

[0060] Specifically, the shutter roller 21 moves toward or away from the door frame 1 through the sliding assembly 22 .

[0061] In this embodiment, the movement of the roller shutter drum 21 is synchronized with the movement of the guide rail mechanism 5 .

[0062] In one embodiment, the rolling shutter cylinder 21 includes two mounting plates 211 and two rolling shutter rails 212.

The rolling shutter rails 212 are installed on the mounting plates 211, and the entrance of the rolling shutter rails 212 is connected to the top of the guide rail mechanism 5.

[0063] Specifically, the diameter of the rolling shutter rail 212 gradually increases from the inside to the outside, and when the rolling shutter mechanism 4 is rolled up, the rolling shutter mechanism 4 is rolled up according to the shape of the rolling shutter rail 212 .

[0064] In this embodiment, the rolling curtain mechanism 4 can be rolled up in an orderly manner, which facilitates the rolling up and unfolding of the rolling curtain mechanism 4.

[0065] In one embodiment, the sliding assembly 22 includes a second sliding rail 221 and a second sliding block 222 . The second sliding rail 221 is fixed to the top of the door frame 1 by rivets, and the second sliding block 222 is fixed to the mounting plate 211 .

[0066] Specifically, there are multiple sliding components 22 , and there is at least one sliding component 22 on each side of the mounting plate 211 .

[0067] In this embodiment, when the rolling shutter cylinder 21 moves, the second sliding block 222 moves along the extension direction of the second sliding rail 221 to reduce the resistance of the rolling shutter cylinder 21 to the movement.

[0068] In one embodiment, the sealing mechanism 6 includes a fixed shell 61, a vertical rod 62, a spring 63, a pressure rod 64, a guide frame 65 and a roller 66.

The guide frame 65 is an inverted triangle.

[0069] Specifically, when the rolling shutter piece 41 moves downward along the guide rail mechanism 5, the transmission rod 35 presses the pressure rod 64 downward, and the pressure rod 64 drives the vertical rod 62 to move downward. During the downward movement of the vertical rod 62, the spring 63 is compressed, and the guide frame 65 moves downward, so that the roller 66 rolls on the side of the guide frame 65. Since the guide frame 65 is an inverted triangle, as the guide frame 65 moves downward, the roller 66 is pushed toward the side of the door frame 1, thereby realizing the movement of the guide rail mechanism 5 toward the side of the door frame 1.

[0070] In this embodiment, without adding an additional driving source, the guide rail mechanism 5 is moved toward the door frame 1, so that the guide rail mechanism 5 is fitted with the door frame 1, and finally, the whole rolling door is better sealed when closed.
