[0038] In order to make the purpose, technical solution and advantages of the embodiments of the present disclosure clearer, the technical solution of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0039] See also Figure 1-14An energy-saving door and window with a fireproof rolling shutter provided in an embodiment of the present invention comprises a frame 1, a rolling shutter is arranged inside the frame 1 through a slide groove 2, an anti-trip buckle 3 is arranged on the rolling shutter, and further comprises: a winding box 4, which is arranged at the upper end of the frame 1, and a winding shaft 5 is rotatably arranged inside the frame 1; a spiral track 6, which is arranged on the inner wall of the winding box 4 around the winding shaft 5 and is connected to the uppermost end of the slide groove 2; a driving component, which is used to connect the winding shaft 5, and the rolling shutter is rolled up along the spiral track 6 through the rotation of the winding shaft 5, and an isolation gap that can be used to accommodate the anti-trip buckle 3 is formed between the inner and outer circles of the rolled-up rolling shutter.

[0040] Specifically, the frame 1 is fixed outside the window for use; the reel box 4 is used to store the rolled-up curtain and is connected to the frame 1 as a whole; the frame 1 and the reel box 4 are both made of fireproof material; the chute 2 is composed of a plurality of groove structures arranged around the inner wall of the frame 1, wherein the upper groove structure connects the chute 2 with the inside of the reel box 4, and then the curtain crosses between the frame 1 and the reel box 4; the length of the curtain is sufficient to cover the entire open surface surrounded by the frame 1; the anti-trip buckle 3 is usually distributed on the curtain at equal intervals vertically. The reel 5 is horizontally arranged near the center position of the reel box 4; two spiral tracks 6 are symmetrically arranged, and are respectively fixed on the inner wall of the reel box 4 corresponding to the two ends of the reel 5, and the spiral track 6 includes an outer end and an inner end, and the outer end of the spiral track 6 faces downward to dock with the upper end of the chute 2, and the spiral track 6 is arranged with a uniformly reduced distance from the outer end to the inner end relative to the axis of the reel 5. The driving assembly includes a driving unit and a thermal clutch assembly. The driving unit is coupled to the winding shaft 5 via the thermal clutch assembly. The driving unit can preferably be a motor. The thermal clutch assembly is used in conjunction with a thermal sensor on the outside of the frame 1 or the winding box 4. When the thermal sensor detects that the temperature outside the window is too high, the thermal clutch assembly is triggered to disconnect the driving unit from the winding shaft 5. The roller shutter connected to the winding shaft 5 automatically falls under the action of gravity to achieve isolation and fire protection. The above driving unit, thermal clutch assembly and thermal sensor are prior arts, and the specific functional principles are not repeated here. When there is no need for fire protection, the driving assembly can normally and actively drive the winding shaft 5 to rotate in the forward and reverse directions. The driving assembly drives the uppermost end of the rolling shutter to move inward along the spiral track 6 to guide the other parts of the rolling shutter to move along the spiral track 6, thereby achieving a winding effect and determining the spacing between the inner and outer circles of the rolling shutter, which is the isolation gap. In actual use of the present technical solution, when the driving component drives the rolling curtain to be rolled up, the uppermost end of the rolling curtain is driven and, under the guidance of the spiral track 6, slides from the outer circle to the inner circle, and the other parts of the rolling curtain also successively make the same movement through the intersection of the slide groove 2 and the spiral track 6, thereby causing the rolling curtain to be rolled up into the winding box 4 in a spiral shape, and an isolation gap is formed between the rolled-up parts of the inner and outer circles, so that the anti-trip buckle 3 is in the isolation gap and will never be in direct contact with the main body of the rolling curtain.

[0041] Compared with the prior art, the energy-saving door and window with a fireproof rolling shutter proposed in the embodiment of the present invention is provided with a spiral track 6 to connect with the slide groove 2 where the rolling shutter is located. In the process of the driving component driving the upper end of the rolling shutter to slide from the outer circle to the inner circle in the spiral track 6, the entire rolling shutter is also rolled up into the winding box 4 in a spiral shape, and an isolation gap is formed between the rolled-up parts of the inner and outer circles of the rolling shutter, so that the anti-trip buckle 3 is in the isolation gap and will not directly contact the rolling shutter body, thereby avoiding the phenomenon that the two ends of the rolling shutter are larger and the middle is smaller after the rolling shutter is rolled up, and preventing the anti-trip buckle 3 from affecting the retraction and release of the rolling shutter, eliminating the accidental occurrence of the anti-trip buckle 3 hanging on or scratching the rolling shutter.

[0042] As the preferred technical solution of this embodiment, the rolling shutter includes a plurality of sliding rods 7 and fireproof cloths 8 that are alternately connected. The upper and lower ends of the rolling shutter are both arranged with sliding rods 7. The uppermost sliding rod 7 is kept arranged in the spiral track 6 to slide and is driven by the driving assembly. Specifically, the sliding rod 7 is arranged parallel to the winding shaft 5. When the rolling shutter is unfolded, the plurality of sliding rods 7 are arranged at equal intervals. The sliding rod 7 and the fireproof cloth 8 are both made of fireproof material. The fireproof cloth 8 also has weak light transmittance to realize the sunshade function of the rolling shutter. The end of the sliding rod 7 is movably located in the slide groove 2 and can slide in and out of the spiral track 6.

[0043] As the preferred technical solution of this embodiment, the driving component includes a set 9 fixedly arranged on the winding shaft 5, and a telescopic rod 10 is movably arranged in the set 9, and one end of the telescopic rod 10 is hinged to the sliding rod 7 at the uppermost end. Specifically, the telescopic movement direction of the telescopic rod 10 relative to the set 9 is perpendicular to the axial direction of the winding shaft 5; when the winding shaft 5 rotates, the set 9 and the telescopic rod 10 transmit the rotational torque to drive the sliding rod 7 at the uppermost end of the roller blind to rotate around the winding shaft 5. At this time, the sliding rod 7 moves along the vortex track 6 and the radial distance change relative to the winding shaft 5 occurs, which is then reflected to the telescopic rod 10, so that the telescopic rod 10 telescopes and slides relative to the set 9, thereby achieving the condition that only the sliding rod 7 at the uppermost end is driven to move to realize the winding and unwinding function of the roller blind, avoiding the interference problem caused by the inner and outer circles formed by the driving component and the winding of the roller blind.

[0044] In another embodiment of the present invention, a sealing belt 11 and a cam rod 12 are vertically arranged on the inner side of the frame 1 on both sides of the rolling curtain unfolding plane, the cam rod 12 is rotatably connected to the frame 1, and a trigger mechanism is arranged at the bottom of the frame 1. After the rolling curtain is completely dropped and unfolded, the trigger mechanism drives the cam rod 12 to rotate so as to press the side of the rolling curtain tightly against the sealing belt 11. Specifically, the sealing belt 11 and the cam rod 12 are arranged close to the side of the frame 1 and are parallel to the rolling curtain unfolding surface; the sealing belt 11 and the cam rod 12 are made of fire-resistant material; the sealing belt 11 has a certain elasticity; the horizontal cross-section of the cam rod 12 is cam-shaped, and when the rolling curtain is not in a fully dropped state, the cam rod 12 is close to the direction of the sealing belt 11 with the side with the smallest radius, and when the rolling curtain is in a fully dropped state. When in the fully fallen state, the cam rod 12 is close to the sealing belt 11 with the side with the largest radius; the sliding rod 7 at the lowest end of the multiple sliding rods 7 is set to be heavier and thicker, the inner wall width of the slide groove 2 matches the outer diameter of the sliding rod 7 at the lowest end, and the outer diameters of other sliding rods 7 are set to the same; the sliding rod 7 at the lowest end usually does not intersect and enter the vortex track 6, and can be at the uppermost end of the slide groove 2 to maintain the falling trend; the rotation of the cam rod 12 pushes the side of the roller curtain to fit onto the sealing belt 11, thereby ensuring that the movable part of the side of the roller curtain is sealed; the setting of the trigger mechanism is triggered after the roller curtain is completely fallen and unfolded, which does not affect the normal falling of the roller curtain, and ensures the accurate timing of the side sealing of the roller curtain. Compared with the traditional temperature-controlled expansion sealing structure, it has higher triggering accuracy.

[0045] As a preferred technical solution of this embodiment, the trigger mechanism includes an active cavity 13 set at the bottom of the frame 1, and a first gear 14 is rotatably set in the active cavity 13. The lower end of the rotating shaft of the cam rod 12 is coaxially connected to the second gear 15 meshing with the first gear 14 through a coil spring 30. A trigger rod 16 is set on the lower side of the slide groove 2. The descent of the trigger rod 16 links the rotation of the first gear 14. A limit assembly for limiting the rotation of the cam rod 12 is also set in the active cavity 13. The limit assembly cancels the limit when the trigger rod 16 descends to the lowest position. Specifically, the first gear 14 only rotates in the active cavity 13 and remains meshed with the second gear 15; the trigger rod 16 is in the descending stroke of the lowest sliding rod 7 in the slide groove 2; the trigger rod 16 horizontally penetrates into the slide groove 2, and the axial direction is perpendicular to the unfolding surface of the roller blind. In actual use of the present technical solution, when the roller blind falls close to being fully extended, the lowermost sliding rod 7 can push the trigger rod 16 during its descending stroke, and the trigger rod 16 moves downward and links the first gear 14 to rotate, and the first gear 14 meshes with the transmission second gear 15 to rotate. Since the limit assembly keeps the limit cam rod 12 rotating at this time, the second gear 15 rotates relative to the rotating shaft of the cam rod 12, so that the coil spring 30 is deformed and stores elastic potential energy; then, when the roller blind falls to be fully extended, the trigger rod 16 also drops to the lowest position, so that the limit assembly is triggered to cancel the restriction on the rotation of the cam rod 12, and the coil spring 30 releases the elastic potential energy, so that the cam rod 12 rotates immediately, so as to bring the side with the largest radius close to the direction of the sealing belt 11, that is, to press the side of the fully extended roller blind against the sealing belt 11 to achieve sealing.
