A drainage structure for system doors and windows

Abstract

This utility model discloses a drainage structure for a system of doors and windows, including a door and window frame. Slide rails are fixed at the top and bottom of the opening on the front of the door and window frame, respectively. A window frame is installed inside the slide rails, and sliding seats are fixed at both ends of the window frame. A falling cavity is opened inside the slide rails, and an inner and outer linkage plate is installed inside the falling cavity. A guide seat is fixed to the bottom of the falling cavity, and the top surface of the guide seat is an inclined surface from top to bottom. A supporting horizontal plate is installed between the inner and outer linkage plate and the guide seat. A drainage channel is opened inside one side of the door and window frame. After the supporting horizontal plate is removed, the inner and outer linkage plate falls naturally under gravity. Through the inclined surface design of the top surface of the guide seat, the inner and outer linkage plate automatically forms a directional tilt angle. The inclined structure changes the liquid in the guide rail from traditional vertical dripping to rapid sliding along the plate surface, greatly improving the drainage speed.

Description

Technical Field

[0001] This utility model relates to the field of door and window drainage technology, specifically a drainage structure for system doors and windows. Background Technology

[0002] The drainage structure of system windows and doors is usually integrated inside the frame and is specifically designed to drain rainwater or condensation that accumulates in the tracks (especially the bottom track of the window sash). Typically, the drainage system is located in the bottom track of the window frame and mainly uses pre-reserved drainage holes to drain the water from the window and door tracks.

[0003] In the prior art, a type of aluminum alloy door and window with a drainage structure is disclosed in patent publication number "CN221144197U", which relates to the field of door and window technology. Specifically, it is an aluminum alloy door and window with a drainage structure, including a window frame, a door and window body, and a drainage plate. An adjustment box and a traction rope are installed at the rear of the window frame. This aluminum alloy door and window with a drainage structure, through the arrangement of the adjustment box, traction rope, connecting rod, locking block, positioning slider, retraction spring, guide cylinder, adjustment plate, guide rod, push rod, stop block, support rod, and positioning block, provides a convenient opening and closing effect for the drainage outlet. The stop block acts as a barrier, the sealing block improves the sealing of the connection, the positioning block provides positioning, the locking block restricts the position of the positioning block, facilitating the installation and removal of the stop block, and the traction rope prevents the stop block from being lost or falling off, thus improving practicality.

[0004] However, existing technologies still have significant shortcomings. Traditional system door and window drainage structures mainly rely on pre-set drainage holes to drain water. At the same time, the drainage path inside the guide rail is usually a straight channel, which makes it easy for liquid to stagnate in the groove of the guide rail. This makes it impossible to quickly and effectively drain the water inside the guide rail when drainage is needed or during heavy rain. Utility Model Content

[0005] The purpose of this utility model is to provide a drainage structure for system doors and windows to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a drainage structure for a system door and window, including a door and window frame, with slide rails fixed at the top and bottom of the opening on the front of the door and window frame, a window frame installed inside the slide rail, and sliding seats fixed at both ends of the window frame, a falling cavity opened inside the slide rail, an inner and outer linkage plate installed inside the falling cavity, a guide seat fixed to the bottom of the falling cavity, and the top surface of the guide seat being an inclined surface from top to bottom, a supporting cross plate installed between the inner and outer linkage plate and the guide seat, and a drainage channel opened inside one side of the door and window frame.

[0007] As can be seen, in the above technical solution, the inner and outer linkage plates fall naturally under the action of gravity after the support plate is removed. Through the inclined surface design of the top surface of the guide seat, the inner and outer linkage plates automatically form a directional tilt angle. The inclined structure changes the liquid in the guide rail from the traditional vertical dripping to rapid sliding along the plate surface, greatly improving the drainage speed.

[0008] Preferably, the slide block is fitted onto the surface of the corresponding slide rail, and one end of the slide block contacts the top and bottom surfaces of the inner and outer linkage plates and the door and window frame openings, respectively.

[0009] As can be seen, in the above technical solution, the bottom surface of the slide not only abuts against the top surface of the inner and outer linkage plates, but also against the bottom surface of the opening on the front of the door and window frame. Therefore, it will not affect the inner and outer linkage plates when they fall and separate from the slide.

[0010] Preferably, the top surface of the supporting horizontal plate is a plane, and the top surface of the supporting horizontal plate is in contact with the bottom surface of the inner and outer linkage plates, and the bottom surface of the supporting horizontal plate cooperates with the top surface of the guide seat.

[0011] As can be seen, in the above technical solution, the support plate can keep the inner and outer linkage plates in a horizontal state after being inserted between the guide seat and the inner and outer linkage plates, and also plays a supporting role for them.

[0012] Preferably, the supporting cross plate is movably connected to the opening on the front of the door and window frame, and the drainage channel corresponds to the lower part of the inclined inner and outer linkage plate.

[0013] As can be seen, in the above technical solution, the inner and outer linkage plates tilt after descending to the top surface of the guide seat, and the tilted lower part is aligned with the drainage channel, so that the water flows into the drainage channel and is discharged.

[0014] Preferably, the door and window frame has movable cavities on both sides of the front, and the movable cavities are located at the top of the supporting horizontal plate. The movable cavities are respectively provided with racks and gears.

[0015] As can be seen, in the above technical solutions, the rack and pinion, as moving structures, are small in size, easy to install inside the door and window frames, and do not affect the aesthetics.

[0016] Preferably, the support plate has arms fixed on both sides, and the arms are fixed to the bottom surface of the rack, and the gear surface meshes with the top surface of the rack.

[0017] As can be seen, in the above technical solution, the rotation of the gear can cause the rack to move within the moving cavity, thereby driving the arm and the support plate to be pulled out from the opening on the front of the door and window frame.

[0018] Preferably, a driving component is connected at the connection position on the side of the gear, and the rack is slidably connected to the opening on the front of the moving cavity.

[0019] As can be seen, in the above technical solution, the driving component is a drive motor with an independent power module. When it is working, it can move the rack, so that the rack moves from the cover plate that is closed on the front of the moving cavity to the outside.

[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] After the supporting horizontal plate is removed, the inner and outer linkage plates fall naturally under the influence of gravity. Through the inclined surface design of the top surface of the guide seat, the inner and outer linkage plates automatically form a directional tilt angle. The tilting structure changes the liquid in the guide rail from the traditional vertical dripping to rapid sliding along the plate surface, greatly improving the drainage speed. The lower part of the inner and outer linkage plates after tilting is precisely aligned with the drainage channel, forming an unobstructed drainage path, completely avoiding the liquid retention problem common in traditional structures. When it rains or drainage is needed, the automatic removal of the supporting horizontal plate and the falling and tilting process of the linkage plates work together. After the inner and outer linkage plates are reset, they fit tightly with the bottom sliding seat of the window frame, ensuring that the sealing and sound insulation performance of the doors and windows are not affected during daily use. This not only ensures the stability of the window sash sliding during daily use, but also immediately forms an efficient drainage channel when drainage is needed. Attached Figure Description

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Please see Figure 1-7 This utility model provides a technical solution:

[0032] Example 1: A drainage structure for a system door and window: It includes a door / window frame 1, with sliding rails 2 fixed at the top and bottom of the opening on the front of the frame 1. A window frame 3 is installed inside the sliding rails 2, and sliding blocks 4 are fixed at both ends of the window frame 3. The door / window frame 1, sliding rails 2, window frame 3, and sliding blocks 4 at both ends of the window frame 3 constitute the main structure of the system door and window. The window frame 3 can be used to install glass, and the sliding blocks 4 slide within the sliding rails 2 and at both ends of the opening on the front of the window frame, thereby opening or closing the window frame 3. Sealing strips should be added at the locations where sealing strips are required on the door / window frame 1 and window frame 3 to achieve airtightness and prevent... In case of water leakage, a drop cavity 6 is provided inside the slide rail 2. The drop cavity 6 contains an inner and outer linkage plate 5. A guide seat 7 is fixed on the bottom surface of the drop cavity 6. The slide 4 is sleeved on the surface of the corresponding slide rail 2, and one end of the slide 4 contacts the top and bottom surfaces of the inner and outer linkage plate 5 and the opening of the door and window frame 1, respectively. It should be noted that since the bottom surface of the slide 4 not only abuts against the top surface of the inner and outer linkage plate 5, but also against the bottom surface of the opening on the front of the door and window frame 1, it will not affect the inner and outer linkage plate 5 when it falls and separates from the slide 4. Ball bearings or rollers can be added to the bottom of the slide 4 to improve the sliding effect when it contacts the top surface of the inner and outer linkage plate 5.

[0033] Furthermore, the top surface of the guide seat 7 is an inclined surface from top to bottom. A supporting horizontal plate 8 is installed between the inner and outer linkage plate 5 and the guide seat 7. A drainage channel 14 is opened inside one side of the door and window frame 1. The top surface of the supporting horizontal plate 8 is flat and fits against the bottom surface of the inner and outer linkage plate 5. The bottom surface of the supporting horizontal plate 8 cooperates with the top surface of the guide seat 7. The supporting horizontal plate 8 is movably connected to the opening on the front of the door and window frame 1. The drainage channel 14 corresponds to the lower part of the inclined inner and outer linkage plate 5. A falling cavity 6 is opened on the bottom surface of the bottom guide rail, which corresponds to the bottom surface of the opening of the door and window frame 1. The guide seat 7 on the bottom surface of the falling cavity 6 is triangular and the top surface is inclined from top to bottom. The inner and outer linkage plate 5 and the supporting horizontal plate 8 are located in the falling cavity 6. Under normal circumstances, since the top surface of the supporting horizontal plate 8 is flat, it can abut against the bottom surface of the inner and outer linkage plate 5, thus providing support. The bottom surface mates with the top surface of the guide seat 7, ensuring that the inner and outer linkage plates 5 are straight when drainage is not required. When drainage is needed, the support plate 8 automatically pulls out from the opening on the front of the door and window frame 1, creating a falling space in the falling cavity 6. It is worth noting that a sealing strip is provided at the front opening of the door and window frame 1. After the support plate 8 moves out, the sealing strip can prevent water leakage from the inside. The inner and outer linkage plates 5 fall naturally under gravity. Through the inclined surface design of the top surface of the guide seat 7, the inner and outer linkage plates 5 automatically form a directional tilt angle. Through the pre-set drainage channel 14, after the inner and outer linkage plates 5 fall, the drainage channel 14 corresponds to its position, allowing the sliding water to quickly enter the drainage channel 14 and finally be discharged from the outlet. The inclined structure changes the liquid in the guide rail from the traditional vertical dripping to rapid sliding along the plate surface, greatly improving the drainage speed.

[0034] Example 2:

[0035] Based on Embodiment 1, movable cavities 10 are provided inside the front sides of the door and window frame 1, and the movable cavities 10 are located at the top of the supporting horizontal plate 8. A rack 11 and a gear 12 are respectively provided inside the movable cavities 10. Arms 9 are fixed to both sides of the supporting horizontal plate 8, and the arms 9 are fixed to the bottom surface of the rack 11. The surface of the gear 12 meshes with the top surface of the rack 11. A driving component 13 is connected at the connection position on the side of the gear 12, and the rack 11 is slidably connected to the opening on the front of the movable cavity 10. The rack 11 and gear 12 are respectively installed in the movable cavities 10 inside the door and window frame 1. The rack 11 is directly connected to the supporting horizontal plate through the arms 9. Gear 12 is connected to drive component 13 via connecting shaft. Drive component 13 is a motor, which can make gear 12 rotate in a fixed position. Since gear 12 meshes with the top surface of rack 11, rack 11 can be moved when gear 12 rotates, so that support plate 8 can be automatically pulled out. The gear 12 and rack 11 are integrated with the door and window frame 1, making full use of the internal space of the door and window frame 1. When it is necessary to restore the inner and outer linkage plate 5 to its original position, the pinch opening reserved on the top surface of inner and outer linkage plate 5 can be manually pinched upward, and then the support plate 8 can be inserted between inner and outer linkage plate 5 and guide seat 7.

[0036] Working principle: The inner and outer linkage plates 5 fall naturally in the falling cavity 6 under gravity, causing them to fall onto the guide seat 7 below. Since the top surface of the guide seat 7 is an inclined surface from top to bottom, the inner and outer linkage plates 5 cooperate with each other after falling onto the top surface of the guide seat 7, causing them to tilt. This allows the liquid in the guide rail to be quickly discharged into the drainage channel 14 along the inclined direction of the top surface of the inner and outer linkage plates 5, allowing the liquid to drain quickly. Under normal circumstances, the inner and outer linkage plates 5 are supported by the support horizontal plate 8, which keeps them at the position of the bottom slide 4 of the window frame 3. The support horizontal plate 8 can be automatically pulled out from between the inner and outer linkage plates 5 and the guide seat 7 when it rains or when drainage is needed, thus avoiding affecting the falling of the inner and outer linkage plates 5. After the inner and outer linkage plates 5 fall to the specified position, the inclined lower part is aligned with the drainage channel 14 of the door and window frame 1, providing support for the slide 4. When it rains or when drainage is needed in the slide rail 2, it can fall and tilt, thus facilitating the rapid drainage of water inside the slide rail 2.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
