[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0025] This utility model embodiment provides a movable curtain wall system, such as Figure 1-6As shown, the curtain wall includes a curtain wall frame, which is composed of two upper and lower curtain wall beams 1 and two left and right curtain wall columns 2. Several mullion assemblies 3 are installed within the curtain wall frame, dividing it into several inlay slots. Movable sash windows 4 and fixed sash windows 5 are installed on the upper and lower sides of each inlay slot. The fixed sash windows 5 are fixed to the curtain wall beams 1 and include fixed beams and fixed mullions. Each fixed mullion has a lifting slot with a concave edge on its front side. Sliding tracks 6 are installed on the curtain wall columns 2 and mullion assemblies 3. These sliding tracks 6 have staggered and parallel upper and lower guide rails, and the sliding tracks 6 wrap from top to bottom. The movable window 4 comprises interconnected translational inclined grooves, turning guide grooves, and lifting slides, forming an L-shape. The translational inclined grooves gradually slope downwards from back to front, the turning guide grooves are obtuse-angled slides, and the lifting slides extend vertically downwards. The front-to-back length of the translational inclined grooves is greater than the front-to-back width of the fixed window 5. The movable window 4 includes a movable crossbeam and a movable vertical stile. Two guide wheel frames 7 are fixed on the outer side of the movable vertical stile. Guide wheels are provided on the upper guide wheel frames, and the guide wheels are slidably inserted into the sliding rail 6. The guide wheel frames 7 on the movable window 4 are provided with an upper guide wheel frame 7 and a lower guide wheel frame 7 that cooperate with the upper and lower guide rails. The movable crossbeam on the lower side of the movable window 4 and the fixed crossbeam on the upper side of the fixed window are configured as sliding inclined surfaces with an inclination angle equal to that of the translational inclined grooves.
[0026] like Figure 1-2As shown, the lower left and right sides of the movable window sash 4 are connected to a lifting mechanism. The lifting mechanism includes a lifting motor 8, a drive screw 9, a lifting nut 10, a slider base 11, and a positioning slider 12. The lifting motor 8 is fixed to the curtain wall beam 1. The drive screw 9 is connected to the output end of the lifting motor 8. The lifting motor 8 and the drive screw 9 are disposed in the lifting slot. The lifting nut 10 is threadedly sleeved on the drive screw 9. The slider base 11 is fixed on the lifting nut 10 and extends forward. The slider base 11 slides between two concave edges. Under the limiting action of the concave edges, the slider base 11 on the drive screw 9 can only slide up and down on the drive screw 9 and cannot rotate. The slider base 11 is provided with... The positioning slider 12 is slidably connected to the slider guide rail and bolted to the front side of the movable sash window 4. The rotation of the lifting motor 8 can drive the slider base 11 to slide up and down in the lifting slot. During the sliding process, the positioning slider 12 will pull the movable sash window 4 to slide along the sliding track 6. During the sliding process, the guide wheel on the movable sash window 4 slides in the translation inclined groove, which will push the positioning slider 12 to slide back and forth on the slider guide rail until it slides to the turning guide groove. At this time, the movable sash window 4 and the fixed sash window 5 are misaligned in the front and back direction and slide down in the lifting slide groove, so that the movable sash window 4 slides to the rear side of the fixed sash window 5 to complete the folding, and the upper part of the curtain wall frame is fully opened to increase the ventilation and smoke exhaust area of the curtain wall system.
[0027] like Figure 1 , Figure 6 As shown, the curtain wall mullions 2 and the mullion assembly 3 are further configured such that the sides of the mullions facing the mounting slot are set as mutually parallel inclined guide surfaces, and the slider guide rail of the slider base 11 is set parallel to the inclined guide surfaces. This allows the inclined guide surfaces of the curtain wall mullions 2 on both sides of the curtain wall frame to be parallel to each other, and keeps the mullion assemblies 3 on both sides of the curtain wall frame at the bend parallel. This provides parallel guide rails for the curved movable sash window 4 to slide towards the interior side at the bend, avoiding derailment caused by the difference in guide rail width at the bend.
[0028] like Figure 3-5As shown, the mullion assembly 3 includes a mullion base 31, lifting plates 32, and a lifting mechanism. The mullion base 31 includes inclined sidewalls on the left and right sides and guide sidewalls integrally formed on the front and rear sides of the inclined sidewalls. The mullion base 31 is configured as a rhomboid tube parallel to the inclined guide surface. The fixed mullion is fixed to the side of the mullion base 31. Two lifting plates 32 are configured and parallel to each other. The lifting plates 32 slide against the top of the inclined sidewalls. The outer wall of the lifting plate 32 is flush with the sidewall of the mullion base 31. The sliding track 6 is arranged on the lifting plate 32. The lifting groove of the sliding track 6 extends to the mullion base 31. During the up-and-down sliding of the movable sash window 4, the guide wheel can slide from the lifting groove of the lifting plate 32 to the lifting groove of the mullion base 31, completely disengaging from the lifting plate 32. The lower end of the lifting plate 32 and the upper edge of the inclined side wall are configured as mutually cooperating contraction slopes. The front-to-back width of the lifting plate 32 is smaller than the width of the inclined side wall. When the lifting mechanism pulls the lifting plate 32 down, the mutually cooperating contraction slopes generate an inward sliding tendency on the lifting plate 32. The lifting mechanism is located between the two lifting plates 32.
[0029] The lifting mechanism includes an electric lifting rod and two symmetrical movable hinge assemblies. The electric lifting rod includes a top rod base 33 and a telescopic rod 34 mounted on the top rod base 33. The telescopic length of the telescopic rod 34 is greater than or equal to the height of the movable window 4, allowing the movable window 4 to open and close smoothly. The telescopic rod 34 is centrally located between the two lifting plates 32. A downwardly curved vertical rod 35 is fixed to the top of the telescopic rod 34. A telescopic gap is provided between the curved vertical rod 35 and the telescopic rod 34 to allow for smooth opening and closing during telescopic movement. When rod 34 retracts, the bent vertical rod 35 avoids the top rod base 33 and moves smoothly downward, completing the folding action. The movable hinge group is connected between the two lifting plates 32. The movable hinge group includes a connecting contact rod 36 and a pivot connecting rod 37 that is pivotally connected to the connecting contact rod 36 at its end and extends to both sides. The outer ends of the two pivot connecting rods 37 are respectively pivotally connected to the two lifting plates 32. The connecting contact rod 36 of the lower movable hinge group is fixed to the lower end of the bent vertical rod 35, and the connecting contact rod 36 of the upper movable hinge group abuts against the lower side of the curtain wall beam 1.
[0030] Working principle:
[0031] In this invention, when the curtain wall system is opened, the control lifting motor 8 drives the drive screw 9 to rotate. The slider base 11 is fixed on the lifting nut 10. Under the limiting action of the lifting slot, the slider base 11 moves up and down. The positioning slider 12 base 11 restricts the positioning slider 12 in the vertical direction through the slider guide rail. Thus, during the up and down translation of the slider base 11, the movable window 4 is pulled in the vertical direction, causing it to slide along the translation inclined groove, the turning guide groove and the lifting slide groove. Under the guidance of the translation inclined groove, it moves with the fixed window 5 in the front and back directions. As the movable sash 4 and fixed sash 5 gradually shift, they move to the turning guide groove position, where the movable sash 4 and fixed sash 5 are completely offset. Under the pull of the positioning slider 12, the movable sash 4 slides along the turning guide groove to the lifting slide groove position and moves vertically downward along the lifting slide groove until the movable sash 4 slides to the rear side of the fixed sash 5, fully opening the upper part and increasing the ventilation and smoke exhaust area of the curtain wall system. At this time, the guide wheel on the movable sash 4 connected to one side of the lifting plate 32 slides from the lifting slide groove part of the lifting plate 32 into the lifting slide groove part of the mullion base 31, completely disengaging from the lifting plate 32, and the lifting motor 8 stops running.
[0032] The electric lifting rod is controlled to retract. During the retraction process, the bent vertical rod 35 pulls the fixed connecting rod 36 downward. The connecting rod 36 pulls the lifting plate 32 downward through the pivot connecting rod 37. The retraction inclined surface generates an inward retraction thrust on the lifting plate 32. The lifting plates 32 on both sides squeeze the pivot connecting rod 37 inward to rotate, thereby reducing the distance between the two lifting plates 32. When the distance between the lifting plates 32 is less than the width of the inner wall of the mullion base 31, the lifting plate 32 retracts inward into the mullion base 31, which can complete the retraction and folding of the lifting plate 32, further increasing the ventilation and smoke exhaust area of the curtain wall system.
[0033] When the curtain wall system is closed, the electric lifting rod needs to be extended first to push the lifting plate 32 to slide upward until the upper movable hinge group is close to the curtain wall beam 1 at the top of the curtain wall frame. The connecting contact of the movable hinge touches the lower side of the curtain wall beam 1. The squeezing force will cause the pivot connecting rod 37 to push the lifting plate 32 to expand to both sides until it is reset to be flush with the outer side of the mullion base 31. The lifting slide of the mullion base 31 and the lifting slide of the lifting plate 32 are smoothly connected. Then the lifting motor 8 is operated to make the movable window 4 slide and reset along the sliding track 6.
