Description

Technical Field

[0001] This application relates to the field of building technology, and particularly to a sunshade system for curtain walls, doors and windows. Background Art

[0002] A shutter is a type of window style. Through the folding design of the shutter curtain, it provides a sunshading function for doors and windows.

[0003] In the related art, there is designed a hollow glass shutter, which includes a frame body disposed in a wall body and two glass plates disposed inside the frame body. A shutter curtain cavity is formed in the middle of the two glass plates, and a shutter curtain and a lifting control mechanism for driving the shutter curtain to lift are disposed in the shutter curtain cavity; the shutter curtain includes a plurality of blades and a traction rope for driving the blades to lift; setting the shutter curtain between two layers of glass plates can enable the doors and windows to have the functions of heat preservation and energy conservation, and the shutter curtain is lifted and lowered through the lifting control mechanism, so as to achieve the effect of sunshading.

[0004] In view of the above related art, the inventor found that when ventilation is required indoors by opening the window, while the window is opened, the shutter curtain disposed between the two layers of glass plates will move together with the glass plates. At this time, if the sunlight is relatively strong, the shutter curtain cannot play its normal sunshading role, so it needs to be improved. Summary of the Invention

[0005] In order to improve the problem that the hollow glass shutter cannot provide sunshading after the window is opened, this application provides a sunshade system for curtain walls, doors and windows.

[0006] The sunshade system for curtain walls, doors and windows provided by this application adopts the following technical solutions:

[0007] The sunshade system for curtain walls, doors and windows includes a frame body, the frame body includes a fixed frame and a rotating frame, the fixed frame is disposed in a wall body, the rotating frame is rotatably connected to the fixed frame, an inner layer of glass is disposed in the rotating frame, an outer layer of glass is disposed in the fixed frame, an adjustment groove is opened on the inner wall of the fixed frame, the adjustment groove is arranged from the direction of the outer layer of glass towards the direction of the inner layer of glass, a receiving groove is opened on the inner wall of the rotating frame, the receiving groove is communicated with the adjustment groove, a sliding block is disposed on the side wall of the outer layer of glass, the sliding block is slidably connected to the inner wall of the adjustment groove, a driving member for driving the sliding block to slide is disposed in the fixed frame, and a locking member for fixing the outer layer of glass is disposed in the receiving groove; an installation groove is opened on the top wall of the fixed frame, the installation groove is located between the outer layer of glass and the inner layer of glass, a driving box is disposed in the installation groove, a shutter curtain is disposed on the bottom wall of the driving box, a lifting mechanism for driving the shutter curtain to lift is disposed inside the driving box, an air extraction hole is opened at the bottom of the driving box, and an air extractor for extracting the air between the outer layer of glass and the inner layer of glass is communicated with the air extraction hole.

[0008] By adopting the above technical solution, when window ventilation is required, the driving member is used to push the sliding block to slide in the adjustment groove. When the sliding block enters the receiving groove from the adjustment groove, the outer glass will also move from the fixed frame to the rotating frame driven by the sliding block. After being locked by the locking member, the outer glass can be fixed in the rotating frame and rotate together with the rotating frame. In this state, the louver curtain changes from the original state between the inner and outer glasses to a state of being separated from the inner and outer glasses. When window ventilation is required, the shading effect can still be achieved through the louver curtain; when the fixing of the outer glass by the locking member is released, the outer glass can be made to re-enter the adjustment groove, and the air between the outer glass and the inner glass can be evacuated by the air extractor, so that the space between the two glasses returns to the vacuum state again, thereby enabling the window to exert the energy-saving and heat-insulating effect again. Compared with the existing insulating glass louver window, the louver curtain of the present application has more complete functions, higher practicability and flexibility.

[0009] Preferably, the sliding block includes a sliding block body and two mounting pieces. The sliding block body abuts against the side wall of the outer glass facing the adjustment groove. The mounting pieces are connected to the end wall of the sliding block body. The outer glass abuts between the two mounting pieces. A fixing groove for the mounting pieces to be embedded is provided on the side wall of the outer glass. A displacement block is provided on the top wall of the sliding block body. Displacement grooves for the displacement block to slide are provided on the top walls of both the adjustment groove and the receiving groove.

[0010] By adopting the above technical solution, a displacement block is provided on the top wall of the sliding block body, so that the displacement block can be embedded in the displacement groove for sliding, thereby enabling the displacement block to abut against the inner wall of the displacement groove, thus restricting the sliding path of the sliding block and enabling the displacement block to stably slide along the length direction of the displacement groove, so that the sliding block can stably drive the outer glass to slide; by providing a fixing groove on the surface of the outer glass for the mounting pieces to be installed, the connection stability between the sliding block and the outer glass can be effectively improved to enhance the safety of the outer glass during the sliding process.

[0011] Preferably, a locking groove is provided on the top wall of the adjustment groove. A locking piece is rotatably connected in the locking groove. After the locking piece rotates, it abuts against one of the mounting pieces on the side of the sliding block close to the inner glass; a buckle is rotatably connected to the bottom wall of the locking piece. A card slot for the buckle to be inserted is provided on the side wall of the mounting piece. An unlocking knob is rotatably connected to the side of the locking piece facing away from the buckle. A locking cavity is provided in the locking piece. One ends of the unlocking knob and the buckle close to each other extend into the locking cavity. A return torsion spring is sleeved on the peripheral wall of the locking cavity of the unlocking knob. One end lever arm of the return torsion spring is connected to the inner wall of the locking cavity, and the other end lever arm is connected to the unlocking knob. A driving gear is provided at one end of the unlocking knob located in the locking cavity. A driven gear is provided at one end of the buckle located in the locking cavity. The driving gear meshes with the driven gear.

[0012] By adopting the above technical solution, setting the locking piece can effectively maintain the stability of the outer glass when it is not sliding. When the sliding block is located on the side of the adjusting groove away from the inner glass, the locking piece is rotated out of the locking groove, so that the locking piece can abut against the mounting piece on the side close to the inner glass. During the abutting process, the buckle abuts against the outer wall of the card slot, and the buckle deforms to a certain extent under its own elasticity. After the buckle is completely inserted into the card slot, the elastic deformation of the buckle is reset, so that the locking piece can be clamped with the mounting piece, forming the positioning of the sliding block and the inner glass, and improving the problem that the sliding block can slide freely in the adjusting groove, resulting in the instability of the inner glass. Thus, the safety of the window can be effectively improved; when the position of the outer glass needs to be adjusted, only the unlocking knob needs to be rotated. Through the meshing relationship between the driving gear and the driven gear, the buckle is driven to rotate. After the buckle rotates, the elastic part of it loses the abutment of the inner wall of the card slot, and the locking piece can be rotated to make the buckle disengage from the card slot, and the locking piece will also rebound into the locking groove. The sliding block without the limit of the locking piece can slide freely in the adjusting groove, so as to realize the sliding of the outer glass. The structure is simple and is beneficial to improving the stability of the window.

[0013] Preferably, the driving member includes a driving sleeve, a driving knob, a driving screw rod and a pushing piece. The driving sleeve is inserted into the fixed frame and is rotatably connected to the fixed frame. The driving knob is connected to the end wall of the driving sleeve extending out of the fixed frame. A driving groove for arranging the driving screw rod is opened in the fixed frame. One end of the driving screw rod is threadedly connected to the inner wall of the driving sleeve. The pushing piece is connected to the end of the driving screw rod away from the driving sleeve. A driven groove is opened in the inner wall of the adjusting groove, and the driven groove communicates with the driving groove. The pushing piece extends out of the driven groove, and the pushing piece abuts against the mounting piece on the side of the sliding block away from the inner glass.

[0014] By adopting the above technical solution, when the outer glass needs to be slid, first, the locking of the locking piece on the sliding block is released. By rotating the driving knob, the driving sleeve is driven to rotate relative to the fixed frame. Due to the restriction of the inner wall of the driven groove on the pushing piece, when the driving sleeve rotates, the driving screw rod can have a stable support. Thus, through the threaded connection relationship between the driving screw rod and the driving sleeve, the driving screw rod is driven to move along the depth direction of the inner wall of the driving sleeve. When the pushing piece moves towards the inner glass direction, the outer glass can be driven to move through the abutting relationship between the pushing piece and the mounting piece. When the rotating frame is not opened, the sliding block can stably slide from the adjusting groove into the receiving groove, and the outer glass can also stably enter the rotating frame; the driving member of the present application has a simple structure and only needs the user to twist the driving knob to achieve, which is convenient to operate and has high practicability and convenience.

[0015] Preferably, the locking member includes a locking rod, a locking screw, and a gear set. A rotating groove is formed in the inner wall of the rotating frame. One end of the locking rod passes through the rotating frame and is inserted into the rotating groove. The locking rod is rotatably connected to the rotating frame. The locking screw is disposed in the receiving groove. A threaded hole for inserting the locking screw is formed in the side wall of the sliding block. One end of the locking screw passes through the bottom wall of the receiving groove and is inserted into the rotating groove. The gear set is disposed in the rotating groove. Both the locking rod and the locking screw are connected to the gear set, and the gear set drives the locking screw to rotate following the locking rod.

[0016] By adopting the above technical solution, when a part of the sliding block enters the receiving groove, by rotating the locking rod, while the locking rod rotates, it will drive the locking screw in the receiving groove to rotate together through the transmission of the gear set. Through the thread fit between the locking screw and the threaded hole, the sliding block can be locked while entering the receiving groove, so that the outer layer of glass can be stably arranged in the rotating frame, improving safety.

[0017] Preferably, positioning screws are provided on the end walls at both ends of the driving box. A support disk is threadedly connected to the peripheral wall of the positioning screw, and the support disk abuts against the inner wall of the installation groove.

[0018] By adopting the above technical solution, when installing the driving box, only need to rotate the support disk, so that the support disk moves relative to the driving box until the support disks at both ends abut against the inner wall of the installation groove. After being abutted to a tight state, the quick installation of the driving box can be realized. Through the support disk, the driving box, the shutter, etc. can be detachably connected to the frame body, which is convenient for disassembling, repairing and installing the driving box, the shutter, etc., and has high practicability.

[0019] Preferably, the shutter includes a traction rope and a plurality of blades. The traction rope passes through the plurality of blades and the bottom wall of the driving box and is connected to the lifting mechanism. A clamping block is provided on the end wall of each blade. A limiting groove for inserting the clamping block is formed in the inner wall of the fixed frame, and the length direction of the limiting groove is consistent with the lifting direction of the shutter.

[0020] By adopting the above technical solution, a clamping block is provided on the end wall of the blade, and the clamping block can be clamped in the limiting groove, so that the lifting direction of the shutter is restricted. When the shutter is separated from the inner and outer layers of glass, it can maintain its vertical setting even in the use state, improving the problem that the shutter shakes after the wind blows on the shutter from the outside, and enabling the shutter to stably provide a shading effect.

[0021] Preferably, a relief groove is formed in the inner wall of one end of the limiting groove close to the installation groove. A relief piece is slidably connected in the relief groove. An elastic member is provided between the relief piece and the bottom wall of the relief groove, and the elastic member urges the relief piece to extend out of the relief groove.

[0022] By adopting the above technical solution, when installing the Venetian blinds, the give-way piece is pushed so that the give-way piece can be pressed into the give-way groove. At this time, the opening of the limit groove is expanded, making it easier to insert the card block into the limit groove, saving the installation time of the Venetian blinds and improving the installation convenience.

[0023] Preferably, a dust shield is provided in the drive box, and a vent is provided through the dust shield along the thickness direction. The outer wall of the vent away from the exhaust hole is connected to a dust removal bag, and the dust removal bag is connected to the air inlet end of the vacuum pump. A one-way valve is provided on the inner wall of the vent.

[0024] By adopting the above technical solution, after the blinds have been used for a long time, some dust will accumulate inside the drive box as the traction rope is wound, and the dust enters the drive box through the exhaust port and the entrance of the traction rope. If too much dust accumulates, it will cause blockage of the lifting mechanism, affecting its normal operation and posing a safety hazard. By setting a dust shield, the dust can be blocked after entering the drive box, so that the dust is concentrated between the dust shield and the bottom wall of the drive box. When the exhaust fan is working, the dust can be extracted and processed through the dust removal bag. When cleaning magazines, you only need to clean the dust removal bag, which is very convenient.

[0025] Preferably, a screen is rotatably connected to the inner wall of the fixing frame on a side facing away from the outer glass.

[0026] By adopting the above technical solution and arranging a screen window, after the blinds are separated from the inner and outer glass layers, the screen window can block mosquitoes, sundries and the like outside, thereby improving the cleanliness of the indoor environment.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. By setting the outer glass in a slidable form, the Venetian blind can be detached from between the two layers of glass. When the window needs to be opened for ventilation, the Venetian blind will continue to provide a sunshade effect. When the locking member fixing the outer glass is released and the outer glass is restored, the air between the outer and inner glass is extracted by the vacuum pump, and the space between the two layers of glass is restored to a vacuum state, thereby allowing the window to once again perform its energy-saving and heat-insulating functions. Compared with the existing insulating glass blinds, the Venetian blinds of the present application are more comprehensive in functions, more practical and more flexible.

[0029] 2. This application provides structures such as sliding blocks and locking parts so that the outer glass can maintain its own stability during and after sliding, thereby effectively protecting the structural safety of the outer glass. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0041] The following further describes this application in detail with reference to Figure 1-10 the accompanying drawings.

[0042] An embodiment of this application discloses a sunshade system for curtain wall doors and windows. Refer to Figure 1 , including a frame body 1, the frame body 1 includes a fixed frame 11 and a rotating frame 12. The fixed frame 11 is embedded in the wall body, and the fixed frame 11 is used to communicate between the indoors and outdoors. One end of the rotating frame 12 is rotatably connected to the fixed frame 11 through a hinge.

[0043] Refer to Figure 1 and Figure 2 , an inner layer of glass 2 is adhesively provided on the inner wall of the rotating frame 12. The inner layer of glass 2 is arranged at one end of the rotating frame 12 away from the fixed frame 11. An outer layer of glass 3 is slidably arranged in the fixed frame 11. In this embodiment, the size of the outer layer of glass 3 is the same as that of the inner layer of glass 2. When the outer layer of glass 3 enters the rotating frame 12, the outer layer of glass 3 abuts against the inner wall of the rotating frame 12.

[0044] Refer to Figure 2 and Figure 3 , two mutually parallel adjusting grooves 111 are opened on the inner wall of the fixed frame 11, and two mutually parallel accommodating grooves 121 are opened on the inner wall of the rotating frame 12. The accommodating grooves 121 and the adjusting grooves 111 correspond to each other one by one. The adjusting grooves 111 are arranged from the direction of the outer layer of glass 3 towards the direction of the inner layer of glass 2 and communicate with the corresponding accommodating grooves 121; a sliding block 4 is slidably connected in each adjusting groove 111, and the sliding block 4 is connected to the outer layer of glass 3, so as to drive the outer layer of glass 3 to slide.

[0045] Refer to Figure 3 and Figure 4 , the sliding block 4 includes a sliding block 41 and two mounting pieces 42. The sliding block 41 is slidably connected in the adjustment groove 111. Displacement blocks 411 are integrally formed on both the top wall and the bottom wall of the sliding block 41. Displacement grooves 13 for the displacement blocks 411 to be embedded and slid are provided on both the top wall and the bottom wall of the adjustment groove 111 and the accommodation groove 121. The length direction of the displacement groove 13 is the same as the length direction of the adjustment groove 111; the sliding block 41 abuts against the side wall of the outer glass 3 facing the adjustment groove 111. The mounting pieces 42 are arranged on both sides of the sliding block 41. The mounting pieces 42 are connected to the sliding block 41 by gluing. One end of the mounting piece 42 extends out of the adjustment groove 111. The outer glass 3 abuts between the two mounting pieces 42. In this embodiment, during the forming process of the outer glass 3, fixing grooves 31 for the ends of the mounting pieces 42 extending out of the adjustment groove 111 to be embedded are left on both side walls. Through the clamping relationship between the two fixing grooves 31 and the mounting pieces 42, the outer glass 3 can be effectively prevented from falling off the sliding block 4, so as to improve the safety and stability of the outer glass 3 during the movement process.

[0046] Refer to Figure 4 and Figure 5 , a locking groove 113 is provided on the top wall of the adjustment groove 111. The locking groove 113 does not interfere with the displacement groove 13. A locking piece 9 is rotatably connected in the locking groove 113. When the sliding block 4 does not slide in the adjustment groove 111, after the locking piece 9 is rotated out of the locking groove 113, the locking piece 9 will abut against one of the mounting pieces 42 on the side of the sliding direction of the sliding block 4.

[0047] Refer to Figure 5 , a plurality of buckles 91 are rotatably connected to the bottom wall of the locking piece 9. The plurality of buckles 91 are distributed in a circular shape. A clamping groove 421 for the buckles 91 to be inserted is provided on the side wall of the mounting piece 42. In this embodiment, the shape of the clamping groove 421 is adapted to the shape of the buckle 91. When the buckle 91 is not rotated, the length direction of the inner wall of the clamping groove 421 is perpendicular to the length direction of the buckle 91. When the buckle 91 abuts against the outer wall of the clamping groove 421, the buckle 91 will generate a certain deformation due to its own elasticity, and thus enter the clamping groove 421. After losing the abutment against the clamping groove 421, the buckle 91 will recover and abut against the inner wall of the clamping groove 421, so as to realize the positioning of the locking piece 9 for the sliding block 4 and the outer glass 3, so as to improve the stability of the outer glass 3 when the outer glass 3 is not slid.

[0048] Refer to Figure 5The locking piece 9 is rotated to connect the unlocking knob 92 with the side facing away from the buckle 91. A cavity is provided in the locking piece 9 to form a locking cavity 93. The ends of the unlocking knob 92 and the buckle 91 that are close to each other are both located in the locking cavity 93; the unlocking knob 92 is located in the locking cavity 93 and is sleeved with a return torsion spring 94 on the peripheral wall. The force arm of one end of the return torsion spring 94 is connected to the inner wall of the locking cavity 93 by gluing, and the force arm of the other end is connected to the unlocking knob 92. When the unlocking knob 92 is rotated, the return torsion spring 94 will accumulate elastic potential energy. When the unlocking knob 92 is released, the return torsion spring 94 will rotate in the opposite direction under the elasticity of the return torsion spring 94, realizing the unlocking rotation. The reset button 92; the unlocking knob 92 is located in the locking chamber 93, one end of which is connected to the driving gear 95 by a key, and the buckle 91 is located in the locking chamber 93, one end of which is keyed to the driven gear 96. Several driven gears 96 are engaged with the driving gear 95. When the driving gear 95 rotates, the driven gear 96 will drive the corresponding buckle 91 to rotate, so that the length direction of the buckle 91 is consistent with the length direction of the inner wall of the slot 421, so that the buckle 91 can be disengaged from the slot 421, completing the unlocking of the sliding block 4 and the outer glass 3. At this time, the outer glass 3 can slide in the adjustment slot 111 through the sliding block 4.

[0049] Reference Figure 1 and Figure 2 A driving member 5 is disposed within the fixed frame 11 and is used to drive the sliding block 4 to slide toward the receiving groove 121. The driving member 5 includes a driving sleeve 51, a driving knob 52, a driving screw 53, and a pushing piece 54. The driving sleeve 51 is inserted from the side wall of the fixed frame 11 facing the interior of the chamber and is rotationally connected to the fixed frame 11 via a bearing. The driving knob 52 is integrally formed with the end wall of the driving sleeve 51 extending from the fixed frame 11. Rotating the driving knob 52 can drive the driving sleeve 51 to rotate.

[0050] Reference Figure 1 and Figure 2, a driving groove 114 for arranging and moving the driving screw rod 53 is formed inside the fixed frame 11. The length direction of the driving groove 114 is consistent with that of the adjusting groove 111. One end of the driving screw rod 53 is threadedly connected to the inner wall of the driving sleeve 51. The pushing piece 54 is connected to the end wall of the driving screw rod 53 away from the driving sleeve 51 by screws. A driven groove 115 is formed on the inner wall of the adjusting groove 111. The length direction of the driven groove 115 is consistent with that of the adjusting groove 111. The driving groove 114 communicates with the driven groove 115. One end of the pushing piece 54 away from the driving screw rod 53 extends out of the driven groove 115 and abuts against the mounting piece 42 on the side of the sliding block 4 away from the inner layer of glass 2. When the driving sleeve 51 rotates, the inner wall of the driven groove 115 applies a pressing force to the pushing piece 54, so that the driving screw rod 53 can move along the depth direction of the driving sleeve 51 through the threaded engagement relationship with the driving sleeve 51. When the driving screw rod 53 moves towards the inner layer of glass 2, the pushing piece 54 will push the sliding block 4 and the outer layer of glass 3 to slide along the length direction of the adjusting groove 111.

[0051] Refer to Figure 2 and Figure 6 , a locking member 6 is arranged in the receiving groove 121. The locking member 6 is used to fix the outer layer of glass 3 and the sliding block 4 when the outer layer of glass 3 slides into the rotating frame 12 and the sliding block 4 enters the receiving groove 121. The locking member 6 includes a locking rod 61, two locking screw rods 62 and a gear set 63. The locking screw rods 62 and the receiving grooves 121 are in one-to-one correspondence; a rotating groove 122 is formed in the rotating frame 12. One end of the locking rod 61 passes through the side wall of the rotating frame 12 from the side of the rotating frame 12 close to the room and is inserted into the rotating groove 122, and the other end is formed into a knob and abuts against the outer wall of the rotating frame 12. The locking rod 61 is rotatably connected to the rotating frame 12 through a bearing.

[0052] Refer to Figure 3 and Figure 6 , the locking screw rod 62 is arranged in the corresponding receiving groove 121. The length direction of the locking screw rod 62 is consistent with that of the inner wall of the receiving groove 121. A threaded hole 43 for inserting the locking screw rod 62 is formed on the side wall of the sliding block 4. The threaded hole 43 runs through the mounting piece 42 and the sliding block 41. When the locking screw rod 62 rotates, the threaded hole 43 is in threaded engagement with the locking thread, so that the sliding block 4 can stably move in the receiving groove 121 and at the same time fix the sliding block 4 in the receiving groove 121.

[0053] Refer to Figure 3 and Figure 6, one end of the locking screw 62 passes through the bottom wall of the receiving groove 121 and is inserted into the rotating groove 122. The gear set 63 is arranged in the rotating groove 122. The gear set 63 is composed of several mutually meshing gear sets 63. Both the locking rod 61 and the locking screw 62 are connected to one of the gears in the gear set 63. Thus, when the locking rod 61 rotates, it can drive the two locking screws 62 to rotate synchronously through the transmission of the gear set 63, so as to lock the sliding blocks 4 in the two receiving grooves 121.

[0054] Refer to Figure 2 and Figure 7 , an installation groove 112 is formed in the top wall of the fixed frame 11. The installation groove 112 is located between the outer layer of glass 3 and the inner layer of glass 2. A driving box 7 is arranged in the installation groove 112. Positioning screws 74 are welded to the end walls at both ends of the driving box 7. A support disc 75 is threadedly connected to the peripheral wall of the positioning screw 74. After the support disc 75 rotates, it abuts against the inner wall of the installation groove 112. Thus, the rapid installation and disassembly of the driving box 7 can be realized, which is convenient for its regular cleaning and maintenance.

[0055] Refer to Figure 8 and Figure 9 , a louver curtain 8 is arranged on the bottom wall of the driving box 7. The louver curtain 8 includes a traction rope 81 and a plurality of blades 82. A lifting mechanism 71 for driving the louver curtain 8 to lift is arranged inside the driving box 7. The traction rope 81 passes through a plurality of blades 82 and the bottom wall of the driving box 7 and is connected to the lifting mechanism 71. By winding the traction rope 81 by the lifting mechanism 71, the winding of the blades 82 can be realized, so as to retract and extend the louver curtain 8. In this embodiment, a counterweight block is arranged at the bottom of the blade 82 facing away from the driving box 7 to keep the louver curtain 8 retracting and extending vertically; the lifting mechanism 71 includes structures such as a slider, a support seat, a guide rope wheel, a rope winding wheel, and a magnetic block for guiding the traction rope 81.

[0056] Refer to Figure 5 and Figure 8 , a clamping block 821 is integrally formed on the end wall of each blade 82. In this embodiment, the cross section of the clamping block 821 is T-shaped. Limiting grooves 116 for the clamping block 821 to be embedded are formed in the inner walls on both sides of the fixed frame 11 in the vertical direction. The cross section of the limiting groove 116 is also T-shaped. The length direction of the limiting groove 116 is consistent with the lifting direction of the louver curtain 8. Thus, through the constraint of the limiting groove 116 on the clamping block 821, the blade 82 can be lifted and lowered in the vertical direction. Therefore, when the outer layer of glass 3 slides, the louver curtain 8 can remain stable when facing the blowing of the external air flow and continuously shade the sun.

[0057] Refer to Figure 5 , Figure 8 and Figure 10, a relief groove 117 is formed in the inner wall of one end of the limiting groove 116 close to the installation groove 112. A relief piece 118 is slidably connected in the relief groove 117. An elastic member 119 is arranged between the relief piece 118 and the bottom wall of the relief groove 117. In this embodiment, the elastic member 119 is a spring. One end of the elastic member 119 is adhesively connected to the bottom wall of the relief groove 117, and the other end is adhesively connected to the bottom wall of the relief piece 118. The elastic member 119 drives the relief piece 118 to keep extending out of the relief groove 117. After pushing the relief piece 118 towards the inside of the relief groove 117, it is convenient to put the clamping block 821 of the blade 82 into the limiting groove 116, reducing the installation difficulty of the louver curtain 8 and improving the convenience.

[0058] Referring to Figure 9 , a plurality of air extraction holes 72 are formed in the bottom of the driving box 7. A dust-proof plate 76 is arranged in the driving box 7. The lifting mechanism 71 is located above the dust-proof plate. The traction rope 81 passes through the dust-proof plate 76 and is connected to the lifting mechanism 71. A ventilation hole 761 is formed through the dust-proof plate 76 in the thickness direction. A one-way valve 78 is arranged in each ventilation hole 761, so that the gas can only flow in one direction. The outer wall of one end of each ventilation hole 761 facing away from the air extraction hole 72 is communicated with a dust removal bag 77, which is used for dust removal of the air entering the driving box 7 through the air extraction hole 72, thereby cleaning the inside of the driving box 7, effectively improving the problem of easy dust accumulation in the driving box 7, reducing the probability of blockage of the lifting mechanism 71 due to excessive dust, and improving safety; one end of the dust removal bag 77 facing away from the dust-proof plate 76 passes through the driving box 7, and an air extractor 73 is arranged on the top wall of the driving box 7. The dust removal bag 77 is communicated with the air inlet end of the air extractor 73. Thus, after the outer layer of glass 3 is reset, the air between the outer layer of glass 3 and the inner layer of glass 2 can be extracted, so that the window can restore the internal vacuum structure, providing energy-saving and heat-preserving performance.

[0059] Referring to Figure 2 , a window screen 14 is rotatably connected to the inner wall of one side of the fixed frame 11 away from the outer layer of glass 3, so as to continuously block mosquitoes, sundries, etc. for the room after the outer layer of glass 3 moves.

[0060] The implementation principle of the curtain wall door and window sunshade system in the embodiment of the present application is as follows: when it is necessary to open the window for ventilation, after opening the rotating frame 12, the locking of the sliding block 4 by the locking piece 9 is released. After closing the rotating frame 12, the driving member 5 drives the sliding block 4 to slide in the adjustment groove 111 until the sliding block 4 enters the receiving groove 121 from the adjustment groove 111, and the outer layer of glass 3 will also be driven by the sliding block 4 to move from the fixed frame 11 into the rotating frame 12. The locking member 6 is started to lock the sliding block 4 and the outer layer of glass 3. At this time, the louver curtain 8 comes to the outside of the two layers of glass;

[0061] The lifting and lowering mechanism 71 is used to control the lifting and lowering of the louver curtain 8, so that when ventilation is required indoors, the louver curtain 8 does not need to move with the glass and can maintain sunshading. After the outer glass 3 is reset and fixed, the air between the outer glass 3 and the inner glass 2 is evacuated by the air extractor 73, so that the space between the two layers of glass returns to the vacuum state again, enabling the window to once again perform the functions of energy conservation and heat preservation. Compared with the existing insulating glass louver window, the louver curtain 8 of this application has more complete functions, higher practicability and flexibility.

[0062] The above are all preferred embodiments of this application, and the protection scope of this application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
