Description

Technical Field

[0001] The invention relates to the technical field of aluminum profiles, in particular to an aluminum profile for a metal door and window frame. Background Art

[0002] Doors and windows are important components of the building envelope system. Doors and windows are divided into enclosure components or partition components according to their location. Doors and windows generally have functions such as heat preservation, heat insulation, sound insulation, waterproofing, and fire prevention. Door and window frames are important components of doors and windows. Door and window frames are generally classified by material: wooden door and window frames and metal door and window frames. Although wooden door and window frames have excellent heat preservation performance, they block more light, are easy to deform, and have high cost of use. Metal door and window frames are strong and durable, fireproof, block less light, and are economical. Metal door and window frames include steel door and window frames, plastic steel door and window frames, and aluminum profile door and window frames. Among them, aluminum profile door and window frames are the most commonly used, and aluminum profile door and window frames include aluminum alloy door and window frames and broken bridge aluminum door and window frames. Because door and window frames made of aluminum alloy have excellent corrosion resistance, low density and lightness, high strength, suitable for making large-sized doors and windows, combined with broken bridge aluminum design, they can effectively prevent the phenomenon of cold and hot bridges. Therefore, aluminum alloy doors and windows are often used in household doors and windows.

[0003] When making aluminum alloy door and window frames, the aluminum alloy strips must first be cut into corresponding sizes and shapes, and then the aluminum alloy strips are combined and fixed by means of connectors to form aluminum alloy door and window frames. This will cause gaps in the joints. When a typhoon comes, because the typhoon will generate strong wind pressure, it will exert greater pressure on the window sashes and window frames. Under the action of wind pressure, rainwater can easily penetrate into the window frame. In order to drain the rainwater in the window frame, drainage holes are usually opened on the window frame, but the drainage holes are connected to the interior. Although the drainage holes can discharge rainwater on rainy days, when the water is not drained, external dust and mosquitoes can easily enter the room through the drainage holes.

[0004] In view of the above problems, the prior art provides a solution. For example, patent publication number CN103437642B provides a sliding window bottom window frame system with a water outlet device. This solution uses a movable paddle to form a closed and opened state according to the size of the external wind pressure and the flow direction of the water storage. When the external wind pressure is large, the drain hole cover is closed to prevent rainwater from backflowing and the "bubble blowing" phenomenon. When the external wind pressure becomes smaller, the drain hole cover is opened, and the water flows through the drain hole on the drain hole cover to the outside. The prior art will install a movable paddle at the drain hole. Although it can prevent dust and mosquitoes from entering the room through the drain hole when the water is not drained, when the external wind pressure is large, the movable paddle will be tightly fitted to the aluminum profile to block the drain hole, which will prevent rainwater from being discharged through the drain hole. This will cause more and more rainwater to accumulate inside the aluminum profile. When there is too much rainwater, it will seep into the room.

[0005] Therefore, a metal door and window frame aluminum profile is proposed. Summary of the invention

[0006] The purpose of the present invention is to provide a metal door and window frame aluminum profile to solve the problem that the wind pressure is high in typhoon weather, which will cause the movable paddle to be unable to separate from the window frame, thereby causing the drainage hole to be blocked and the rainwater in the window frame to be unable to be discharged. When the window sash is closed, the inner baffle and the outer baffle move horizontally to expose the inner drainage hole and the outer drainage hole, and the long water guide plate, the short water guide plate and the ribs cooperate with each other to guide the flow of rainwater, which can ensure that rainwater can still be discharged from the inner drainage hole and the outer drainage hole under strong wind conditions.

[0007] To achieve the above object, the present invention provides the following technical solutions:

[0008] A metal door and window frame aluminum profile, including a horizontal profile, a vertical profile and a window sash, and also including an extrusion mechanism, an inner baffle, a connecting mechanism, an outer baffle, an inner drain hole and an outer drain hole. The extrusion mechanism is connected to the horizontal profile, the inner baffle is connected to the extrusion mechanism, the connecting mechanism is connected to the inner baffle, and the outer baffle is connected to the connecting mechanism. The drain hole and the outer drain hole are both opened inside the horizontal profile. When the window sash is closed, the extrusion mechanism squeezes the inner baffle. When the inner baffle is squeezed, the connecting mechanism drives the outer baffle to move and keep it parallel to the inner baffle. When the inner baffle and the outer baffle move, the inner drain hole and the outer drain hole are exposed, and rainwater is discharged from the horizontal profile through the inner drain hole, the connecting mechanism and the outer drain hole in turn.

[0009] In the above scheme, the window sash will squeeze the squeezing mechanism when it is closed, and then the inner baffle plate and the outer baffle plate will be controlled by the connecting mechanism to change from an offset setting to a parallel setting, and the inner drainage hole and the outer drainage hole will be exposed at the same time to facilitate the discharge of rainwater. The rainwater can be diverted by the connecting mechanism while the connection strength between the inner baffle plate and the outer baffle plate can be improved, thereby improving the strength of the cross profile and preventing the cross profile from deforming in wind and rain. The state of the inner drainage hole and the outer drainage hole is changed according to the state of the window sash. The inner drainage hole and the outer drainage hole are blocked or exposed, which can not only prevent external dust or mosquitoes from entering the room when the window sash is opened, but also facilitate the drainage of rainwater in the cross profile when the window sash is closed to avoid the accumulation of rainwater.

[0010] Preferably, the inner drainage hole and the outer drainage hole have the same aperture, and the inner baffle plate and the outer baffle plate match the inner drainage hole and the outer drainage hole respectively.

[0011] In the above scheme, the drainage balance between the inner drainage hole and the outer drainage hole can be ensured, avoiding the situation where one rainwater has a low passing efficiency and the other has a high passing efficiency.

[0012] Preferably, two inner drainage holes and two outer drainage holes are symmetrically arranged, and the two inner drainage holes divide the horizontal profile into three equal parts.

[0013] In the above scheme, the area used for water storage by the horizontal profile is divided by each inner drainage hole and the outer drainage, which can ensure that the drainage range of the inner drainage hole and the outer drainage is consistent, avoid the situation where one of the inner drainage holes or the outer drainage is blocked due to inconsistent drainage areas, and ensure smooth flow of rainwater.

[0014] Preferably, an inner movable groove and an outer movable groove are respectively opened inside the horizontal profile, the inner movable groove and the outer movable groove are staggered, the inner movable groove and the inner drainage hole are connected, and the outer movable groove and the outer drainage hole are connected.

[0015] In the above solution, movement space can be provided for the inner baffle plate and the outer baffle plate, so that the inner baffle plate and the outer baffle plate can respectively cover or expose the inner drainage hole and the outer drainage hole.

[0016] Optionally, the drainage hole can be left unblocked and rainwater can be directly drained through the drainage hole. Alternatively, the drainage hole can be blocked first and the blocking object can be removed when drainage is required. Since the drainage hole connects indoors and outdoors, if the drainage hole is not blocked, dust and mosquitoes from the outside can easily enter the room through the drainage hole, and it is easy to cause blockage in the drainage hole, thereby reducing the drainage effect. Therefore, the method of not blocking the drainage hole is not adopted.

[0017] Preferably, the extrusion mechanism includes a pressure plate, a connecting rod, a return spring, an extrusion block, a pressure block, a limit block, a buffer spring and a push rod. A rectangular groove is provided on one side of the cross profile, the pressure plate matches the rectangular groove, the connecting rod is installed at one end of the pressure plate, the return spring is sleeved on the outside of the connecting rod, the extrusion block is installed at one end of the connecting rod and the return spring, the pressure block matches the extrusion block, the limit blocks are installed at both ends of the pressure block, a limit groove matching the limit block is provided inside the cross profile, the buffer spring is installed between the limit block and the cross profile, and the push rod is installed between the pressure block and the inner baffle.

[0018] In the above scheme, the window sash will squeeze the pressure plate when it is closed, and the pressure will drive the extrusion block to squeeze the pressure block, and then push the inner baffle plate through the push rod, and then drive the outer baffle plate to move under the action of the connecting mechanism, so as to expose the inner drainage hole and the outer drainage hole, thereby facilitating the discharge of rainwater. When the inner baffle plate covers the inner drainage hole and the outer baffle plate covers the outer drainage hole, outside dust or mosquitoes cannot enter the room.

[0019] Preferably, an extrusion slope is provided at the bottom end of the extrusion block, and a pressure slope is provided at the top end of the pressure block, and the extrusion slope and the pressure slope are both set at 45 degrees.

[0020] In the above scheme, the pressure block can be controlled to descend more smoothly, thereby improving the smoothness of the movement of the inner baffle plate and the outer baffle plate and avoiding jamming.

[0021] Optionally, a magnetic shield can be installed on the outside of the window frame to block the drainage hole, or a flat-pushing shield can be used to block the drainage hole. However, when the external wind is strong, pressure will be exerted on the magnetic shield, causing the shield to fit more closely to the window frame, and it will be difficult to separate the shield from the window frame by the force of the water flow, resulting in rainwater being unable to drain away through the drainage hole. This will cause rainwater to gather in the window frame, and when too much rainwater gathers, it will seep into the room.

[0022] Preferably, the connecting mechanism includes a front piston sleeve, a piston rod, a rear piston sleeve and a drainage unit, the front piston sleeve is installed at one end of the inner baffle, the piston rod is connected to the front piston sleeve, the rear piston sleeve is connected to the piston rod, and the front piston sleeve and the rear piston sleeve have the same specifications.

[0023] In the above scheme, the push rod simultaneously drives the outer baffle plate to move when pushing the inner baffle plate to move, which can simultaneously block or expose the inner drainage hole and the outer drainage hole, can divert rainwater discharged from the inner drainage hole, and can support the inner baffle plate and the outer baffle plate, thereby improving the strength of the cross-section.

[0024] Preferably, when the inner baffle plate and the outer baffle plate are staggered, they form a step shape with the front piston sleeve, the piston rod and the rear piston sleeve, and when the inner baffle plate and the outer baffle plate are correspondingly arranged, they form an "I" shape with the front piston sleeve, the piston rod and the rear piston sleeve.

[0025] In the above scheme, the stability can be improved while reducing the total mass of the inner baffle plate and the outer baffle plate. At the same time, the strength of the connection between the inner baffle plate and the outer baffle plate can be improved, and the bending resistance of the inner baffle plate and the outer baffle plate can be improved to withstand stronger wind and rain.

[0026] Preferably, the drainage unit includes a pull rod, a long water guide bar, a short water guide bar, a water retaining bar and a rib. The pull rod is connected to the inner baffle plate. The long water guide bar is installed on one side of the inner drainage hole. The short water guide bar is installed on one end of the inner baffle plate. The water retaining bar cooperates with the long water guide bar. The ribs are respectively installed on the outer walls of the front piston sleeve and the rear piston sleeve, and are respectively provided in one group, and a guide groove is formed between each group of ribs.

[0027] In the above scheme, when the inner baffle moves and no longer blocks the inner drainage hole, the long water guide bar and the water retaining bar will be separated by the pull rod, and the vertical state will be changed to an inclined state. Then the rainwater in the cross profile will flow downward through the long water guide bar and the short water guide bar, and then be guided to the outer drainage hole through the guide groove between the ribs, thereby realizing the discharge of rainwater and avoiding rainwater remaining inside the cross profile during discharge.

[0028] Preferably, the guide groove of the front piston sleeve is arranged in the opposite direction to the guide groove of the rear piston sleeve, the opening of the guide groove of the front piston sleeve faces the long water guide strip, and the opening of the guide groove of the rear piston sleeve faces the external drainage hole.

[0029] In the above scheme, the position of rainwater can be changed, so that the rainwater can be discharged conveniently.

[0030] Compared with the prior art, the present invention has the following beneficial effects:

[0031] 1. When it is not raining, the inner baffle and the outer baffle cover the inner drainage hole and the outer drainage hole respectively, and cooperate with the screen window to prevent dust and mosquitoes from outside from entering the room. When it rains, the inner baffle and the outer baffle no longer cover the inner drainage hole and the outer drainage hole, and the inner drainage hole and the outer drainage hole are exposed, which can avoid the low pressure of the outside in strong wind and rain weather. The outer baffle covers the outer drainage hole, which can ensure the smooth flow of the inner and outer drainage holes, and can facilitate the drainage of rainwater in the horizontal profile, avoiding the accumulation of rainwater in the horizontal profile.

[0032] 2. Dividing the horizontal profile into three equal parts through internal drainage holes can ensure that the drainage area of ​​each internal drainage hole is consistent, and each internal drainage hole is opened in the center of the drainage area, which can shorten the flow path of rainwater in the horizontal profile and shorten the friction time between rainwater and the horizontal profile, so that rainwater can flow into the internal drainage holes in a short time, thereby preventing rainwater from remaining inside the horizontal profile and improving drainage efficiency.

[0033] 3. Through the cooperation of long water guide strips, short water guide strips and ribs, rainwater in the horizontal profile can be diverted. Through the cooperation of the front piston sleeve, rear piston sleeve and ribs, not only can the position of rainwater be changed, but also the rainwater can be directly transported from the inner drainage hole to the outer drainage hole, and the flow of rainwater can be regularized to flow in a specified path, which can prevent rainwater from falling directly inside the horizontal profile and gathering, and can shorten the flow path of rainwater during discharge, thereby improving the discharge efficiency of rainwater. At the same time, when the window sash is closed, the front piston sleeve can be connected to the rear piston sleeve to form an I-shape between the inner baffle and the outer baffle, which can improve the strength of the connection between the inner baffle and the outer baffle, and can prevent the horizontal profile from being deformed due to strong wind and rain, thereby improving the stability of the installation of the horizontal profile.

DETAILED DESCRIPTION

[0045] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. However, the embodiments described below are only some embodiments of the present invention, not all of them. If other embodiments of ordinary technicians in this field are obtained without making creative work, they all belong to the protection scope of the present invention.

[0046] Reference Figures 1 to 5 , Figure 7 and Fig. 9 A metal door and window frame aluminum profile, comprising a horizontal profile 1, a vertical profile 2 and a window sash 3. The top of the horizontal profile 1 is inclined, so that rainwater can be gathered at the lowest end of the horizontal profile 1 instead of flowing toward the indoor direction on the horizontal profile 1, thereby preventing rainwater from seeping into the indoor. The profile also comprises an extrusion mechanism 4, an inner baffle 5, a connecting mechanism 6, an outer baffle 7, an inner drainage hole 8 and an outer drainage hole 9. The extrusion mechanism 4 is connected to the horizontal profile 1, and the inner baffle 5 is connected to the extrusion mechanism 4. The extrusion mechanism 4 can control the inner baffle 5 to move horizontally when the window sash 3 is closed or opened to cover or expose the inner drainage hole 8, and can be converted according to the state of the window sash 3 to meet different usage requirements. The connecting mechanism 6 is connected to the inner baffle 5, and the outer baffle 7 is connected to the connecting mechanism 6. The inner baffle 5 can be connected to the outer drainage hole 8 through the connecting mechanism 6. The baffle plate 7 is connected, which can not only guide the discharged rainwater, but also improve the connection strength between the inner baffle plate 5 and the outer baffle plate 7, improve the strength of the cross profile 1, and prevent the cross profile 1 from deforming in strong wind and rain weather. The inner drainage hole 8 and the outer drainage hole 9 are both opened inside the cross profile 1. The rainwater that penetrates into the surface of the cross profile 1 can be discharged into the cross profile 1 through the inner drainage hole 8, and the rainwater discharged into the cross profile 1 can be discharged to the outside through the outer drainage hole 9. When the window sash 3 is closed, the squeezing mechanism 4 squeezes the inner baffle plate 5. When the inner baffle plate 5 is squeezed, the connecting mechanism 6 drives the outer baffle plate 7 to move and keeps it parallel with the inner baffle plate 5. When the inner baffle plate 5 and the outer baffle plate 7 move, the inner drainage hole 8 and the outer drainage hole 9 are exposed, and the rainwater is discharged from the cross profile 1 through the inner drainage hole 8, the connecting mechanism 6 and the outer drainage hole 9 in turn;

[0047] The apertures of the inner drainage hole 8 and the outer drainage hole 9 are consistent. Through the above-mentioned arrangement, the drainage volume of the inner drainage hole 8 and the outer drainage hole 9 can be guaranteed to be consistent, and the drainage balance can be maintained. The inner baffle plate 5 and the outer baffle plate 7 are matched with the inner drainage hole 8 and the outer drainage hole 9 respectively. According to the needs of use, the inner drainage hole 8 can be blocked or exposed by the inner baffle plate 5, and the outer baffle plate 7 synchronously blocks or exposes the outer drainage hole 9. There are two inner drainage holes 8 and two outer drainage holes 9 symmetrically arranged. Through the above-mentioned arrangement, it can be ensured that both ends of the cross profile 1 can drain water, and the drainage efficiency can be improved. The two inner drainage holes 8 divide the cross profile 1 into three equal parts. Through the above-mentioned arrangement, the drainage area of ​​each inner drainage hole 8 can be guaranteed to be consistent, which can avoid the situation where one has a large drainage volume and the other has a small drainage volume, and can ensure that each The drainage uniformity of the inner drainage hole 8, if one has a larger drainage volume and the other has a smaller drainage volume, will easily cause the inner drainage hole 8 with a larger drainage volume to have "bubbles", which will easily cause rainwater to splash into the room. The inner movable groove 10 and the outer movable groove 11 are respectively opened inside the cross profile 1. Through the above arrangement, space can be provided for the movement of the inner baffle plate 5 and the outer baffle plate 7. The inner movable groove 10 and the outer movable groove 11 are staggered. Through the above arrangement, the staggered arrangement between the inner drainage hole 8 and the outer drainage hole 9 can be achieved, the drainage efficiency of the inner drainage hole 8 and the outer drainage hole 9 can be improved, the anti-overflow ability can be enhanced, and the pressure of the water flow can be dispersed, which can improve the drainage effect. The inner movable groove 10 is connected to the inner drainage hole 8, and the outer movable groove 11 is connected to the outer drainage hole 9.

[0048] As an embodiment of the present invention, refer to Figure 6The extrusion mechanism 4 includes a pressure plate 41, a connecting rod 42, a return spring 43, an extrusion block 44, a pressure block 45, a limit block 46, a buffer spring 48 and a push rod 47. A rectangular groove 49 is provided on one side of the horizontal profile 1. The pressure plate 41 matches the rectangular groove 49. Through the setting of the rectangular groove 49, the pressure plate 41 can be stored when the pressure plate 41 is squeezed by the window sash 3, ensuring that the pressure plate 41 and the horizontal profile 1 remain flush, which can improve the tightness of the fit between the window sash 3, the pressure plate 41 and the horizontal profile 1, and can reduce the possibility of rainwater penetrating downward along the window sash 3. The connecting rod 42 is installed at one end of the pressure plate 41, and the return spring 43 is sleeved on the connecting rod 42. On the outside of the rod 42, through the setting of the return spring 43, the pressure plate 41 can be controlled to disengage from the rectangular groove 49 after the pressure plate 41 loses the pressure of the window sash 3, so as to realize the reset of the pressure plate 41. The extrusion block 44 is installed on the connecting rod 42 and one end of the return spring 43. Through the setting of the connecting rod 42, pressure can be applied to the extrusion block 44 when the pressure plate 41 is squeezed, thereby driving the extrusion block 44 to squeeze the pressure block 45. The pressure block 45 cooperates with the extrusion block 44. The bottom end of the extrusion block 44 is provided with an extrusion slope 441, and the top end of the pressure block 45 is provided with a pressure slope 451. The extrusion slope 441 and the pressure slope 451 are both set at 45 degrees, and the extrusion The slope 441 cooperates with the pressure slope 451. Through the above arrangement, the pressure block 45 can be squeezed during the movement of the squeezing block 44, so that the pressure block 45 can be controlled to descend. By setting the 45-degree squeezing slope 441 and the pressure slope 451, it can be ensured that the pressure block 45 is smoothly squeezed. The limit blocks 46 are installed at both ends of the pressure block 45. The inside of the horizontal profile 1 is provided with a limit groove 410 that cooperates with the limit block 46. The limit block 46 cooperates with the limit groove 410 to limit the lifting and lowering of the pressure block 45, which can ensure that the pressure block 45 moves along the specified path during lifting and lowering, and prevent the pressure block 45 from moving. The push rod 47 is installed between the pressure block 45 and the inner baffle plate 5. The push rod 47 can push or pull the inner baffle plate 5 when the pressure block 45 moves, thereby realizing the shielding or exposure of the inner drainage hole 8, so as to achieve the purpose of matching the state of the inner drainage hole 8 with the state of the window sash 3.

[0049] As an embodiment of the present invention, refer to Figure 8 and Fig.10The connecting mechanism 6 includes a front piston sleeve 61, a piston rod 62, a rear piston sleeve 63 and a drainage unit 64. The front piston sleeve 61 is installed at one end of the inner baffle plate 5, the piston rod 62 is connected to the front piston sleeve 61, and the rear piston sleeve 63 is connected to the piston rod 62. The front piston sleeve 61, the piston rod 62 and the rear piston sleeve 63 cooperate with each other to form a double-end piston device. When the front piston sleeve 61 and the rear piston sleeve 63 move with the inner baffle plate 5 and the outer baffle plate 7 respectively, the distance between the front piston sleeve 61 and the rear piston sleeve 63 will change, and at the same time, the two ends of the piston rod 62 move in the front piston sleeve 61 and the rear piston sleeve 63 respectively, which can meet the moving distance of the inner baffle plate 5 and the outer baffle plate 7. The specifications of the front piston sleeve 61 and the rear piston sleeve 63 are consistent. The above arrangement can ensure balance and avoid inconsistent displacement of the two ends of the piston rod 62. When the inner baffle plate 5 and the outer baffle plate 7 are staggered, they are stepped with the front piston sleeve 61, the piston rod 62 and the rear piston sleeve 63. The piston rod 62 is rotatably installed inside the horizontal profile 1, so that when the inner baffle plate 5 and the outer baffle plate 7 are staggered, a lever is formed with the front piston sleeve 61, the piston rod 62 and the rear piston sleeve 63. Through the above arrangement, it can be ensured that the inner baffle plate 5 and the outer baffle plate 7 move in the opposite direction or towards each other. When the inner baffle plate 5 and the outer baffle plate 7 are correspondingly arranged, they are in an "I" shape with the front piston sleeve 61, the piston rod 62 and the rear piston sleeve 63. Through the above arrangement, the strength of the connection between the inner baffle plate 5 and the outer baffle plate 7 can be improved, and the horizontal profile 1 can be prevented from being deformed by strong wind pressure in typhoon weather.

[0050] As an embodiment of the present invention, refer to Figure 8 and Fig.10The drainage unit 64 includes a pull rod 641, a long water guide bar 642, a short water guide bar 643, a water retaining bar 644 and a rib 645. The pull rod 641 is connected to the inner baffle 5. The pull rod 641 can pull or push the long water guide bar 642 when the inner baffle 5 moves, so as to change the state of the long water guide bar 642. When the long water guide bar 642 is in a vertical state, the inner baffle 5 blocks the inner drainage hole 8. When the long water guide bar 642 is in an inclined state, the inner drainage hole 8 is exposed, so as to facilitate the discharge of rainwater on the horizontal profile 1 and guide the rainwater. , the long water guide strip 642 is installed on one side of the inner drainage hole 8, and the short water guide strip 643 is installed on one end of the inner baffle plate 5. The long water guide strip 642 and the short water guide strip 643 are both inclined, and one end of the short water guide strip 643 points to the long water guide strip 642. When the inner drainage hole 8 is exposed, the short water guide strip 643 is located above the long water guide strip 642, and the water retaining strip 644 cooperates with the long water guide strip 642. Through the above arrangement, rainwater on one side of the inner drainage hole 8 can be diverted to the long water guide strip 642 through the short water guide strip 643, and the water retaining strip 644 fits with the inner wall of the horizontal profile 1, and the water retaining strip 644 is in contact with the inner wall of the horizontal profile 1. The cross section of the strip 644 is L-shaped. Through the above arrangement, rainwater can be prevented from flowing to the other side of the water retaining strip 644, shortening the space in the horizontal profile 1, and at the same time, the long water guide strip 642 can be stored. The long water guide strip 642 cooperates with the water retaining strip 644 to improve the strength of the horizontal profile 1 when the window sash 3 is opened. The ribs 645 are respectively installed on the outer walls of the front piston sleeve 61 and the rear piston sleeve 63, and are respectively provided with a group. A guide groove 646 is formed between each group of ribs 645. The ribs 645 are arranged around the front piston sleeve 61 and the rear piston sleeve 63. The ribs 645 is an arc-shaped setting. Through the above setting, the rainwater guided by the long water guide strip 642 can be transported. The guide groove 646 of the front piston sleeve 61 and the guide groove 646 of the rear piston sleeve 63 are set in opposite directions. The guide groove 646 of the front piston sleeve 61 opens toward the long water guide strip 642, and the guide groove 646 of the rear piston sleeve 63 opens toward the outer drainage hole 9. Through the above setting, the trajectory of rainwater discharge can be changed, and the rainwater in the inner drainage hole 8 can be guided to the outer drainage hole 9, which can prevent rainwater from falling directly into the inside of the horizontal profile 1, resulting in the inability to discharge rainwater cleanly.

[0051] Working principle: When a typhoon comes, the window sash 3 is closed. When the window sash 3 is closed, the inner baffle 5 is driven to move in the inner moving groove 10 through the squeezing mechanism 4, and the outer baffle 7 is driven to move in the outer moving groove 11 through the connecting mechanism 6. The inner baffle 5 and the outer baffle 7 are changed from being staggered to being vertically arranged.

[0052] Specifically: when the user closes the window sash 3, the window sash 3 presses the pressure plate 41. When the pressure plate 41 is pressed, it pushes the pressing block 44 through the connecting rod 42, and at the same time pushes the return spring 43. When the pressing block 44 is pushed, the pressing slope 441 slides on the pressure slope 451, thereby pressing the pressure block 45 downward. When the pressure block 45 is subjected to the pressure from the pressing block 44, it drives the limit block 46 to press the buffer spring 48, and at the same time, it can push the outer baffle 7 to move in the outer moving groove 11 through the push rod 47, thereby exposing the outer drainage hole 9.

[0053] When the outer baffle plate 7 moves, it will drive the rear piston sleeve 63 to rotate, and drive the front piston sleeve 61 to rotate through the piston rod 62. When the front piston sleeve 61 and the rear piston sleeve 63 rotate, the two ends of the piston rod 62 will gradually move toward the ends of the front piston sleeve 61 and the rear piston sleeve 63, and the front piston sleeve 61 and the rear piston sleeve 63 will gradually approach each other, and at the same time, it will drive the inner baffle plate 5 to move in the inner moving groove 10 and expose the inner drainage hole 8. When the inner baffle plate 5 moves, The short water guide bar 643 is driven to move synchronously, and the long water guide bar 642 can be pulled by the pull rod 641 to change the long water guide bar 642 from a vertical state to an inclined state. When the outer baffle plate 7 moves to one end of the outer movable groove 11, the piston rod 62 completely enters the front piston sleeve 61 and the rear piston sleeve 63, and the ribs 645 on the front piston sleeve 61 and the rear piston sleeve 63 are connected, and the front piston sleeve 61 and the rear piston sleeve 63 are changed from an inclined state to a vertical state.

[0054] The rainwater flows through the inner drainage hole 8 to the long water guide strip 642 and the short water guide strip 643. The rainwater on the short water guide strip 643 eventually flows to the long water guide strip 642. The rainwater flows along the long water guide strip 642 to the guide groove 646 formed by the ribs 645. The rainwater flows along the guide groove 646 to the outer drainage hole 9 and is discharged from the outer drainage hole 9.

[0055] When the window sash 3 is opened, the opposite operation to the above is performed.

The appended claims and their equivalents define the scope of the present invention.
