[0015] Working Principle: When the push handle is operated, the fixed block and the slider in the sliding groove on the inner wall of the window frame form a double-point support through the connecting plate and the rotating shaft, driving the window sash to flip and open; at the same time, the rotating block drives the Y-shaped groove mechanism to further expand the angle, realizing multi-angle locking. When closing, the water retaining strips and sound insulation strips at the top and bottom of the window sash form a double sealing line of defense. Turning the handle drives the first and second clamping plates to synchronously snap into the slots, forming a two-point locking structure to ensure airtightness. When it rains, the water guide groove on one side of the window frame collects rainwater, which flows into the water collection tank through the inclined surface of the window sash. The funnel-shaped inner wall causes the rainwater to gather at the lowest point and be discharged to the outside through the drainage hole. The dustproof strip prevents dust from falling into the drainage channel.

[0016] The present invention provides a flip-type energy-saving window that can be opened at a large angle. It has the following beneficial effects:

[0017] 1. This invention enhances functionality through its wide-angle opening flip energy-saving window.

Locking and drainage functions also ensure safe use, comprehensively optimizing the practical functions of windows in buildings. This addresses the functional deficiencies of traditional windows.

[0018] 2. The present invention enables the window sash to be opened at a wide angle by flipping it relative to the window frame, making it easier to clean and maintain the window inside and outside. Furthermore, the window sash opening angle can be adjusted according to actual needs to meet usage requirements, thus solving the problem of limited opening angles of traditional windows.

[0019] 3. This invention achieves angle control of the window sash through the unique structure of the opening and closing mechanism, expanding the range of angles the window sash can open, enhancing the flexibility of window opening operations, and meeting diverse needs such as ventilation, lighting, and external operation. This solves the problem that traditional windows can only open to a limited angle.

[0020] 4. The present invention effectively secures the window sash in place through its locking and unlocking functions, ensuring stability in the closed state, maintaining the window's tightness, and guaranteeing both indoor environmental independence and user safety. This solves the problem of traditional window locking being unreliable and prone to accidental opening. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0031] The following will clearly and completely describe the technical solution of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] Please see the attached Figure 1 -Attached Figure 9 An embodiment of the present invention provides a flip-type energy-saving window that can be opened at a large angle, including a window frame 1, and slide grooves 6 are symmetrically provided on the top and bottom ends of the inner wall of the window frame 1. An opening and closing mechanism is provided in the slide groove 6 of the window frame 1, and a window sash 2 is provided on one side of the opening and closing mechanism. A push handle 3 is provided on one side of the middle part of the window sash 2, and a water retaining strip 7 is provided on the top and bottom ends of the window sash 2. A sound insulation strip 11 is provided on one side of the water retaining strip 7, and one side of the sound insulation strip 11 is provided at the top and bottom ends of the window sash 2. A locking mechanism is provided on the outer wall of the window frame 1, and the push handle 3 is provided above the locking mechanism. A water guide groove 26 is symmetrically provided on one side of the window frame 1, and the shape of the water guide groove 26 is a cylindrical groove. A drainage mechanism is provided at the bottom end of the inner wall of the window frame 1.

[0033] Specifically, the slide grooves 6 at the top and bottom of the inner wall of the window frame 1 provide sliding tracks for the opening and closing mechanism. The opening and closing mechanism is assembled in the slide groove 6 and connected to the window sash 2. By applying force through the push handle 3 and with the help of the guiding effect of the slide groove 6, the window sash 2 is driven to move along a specific track, realizing the flipping and large-angle opening of the window sash 2 to meet different ventilation and cleaning needs. The water retaining strips 7 and sound insulation strips 11 at the top and bottom of the window sash 2 fill the gap between the window sash 2 and the window frame 1 when the two are closed. The water retaining strip 7 blocks rainwater infiltration, and the sound insulation strip 11 cuts off sound propagation, thereby enhancing the overall sealing of the window body after closing and reducing energy exchange. The locking mechanism on the outer wall of the window frame 1 cooperates with the corresponding part of the window sash 2. The push handle 3 is operated to link the locking mechanism, and the window sash 2 is firmly fixed to the window frame 1 by mechanical engagement to prevent unexpected opening and ensure safety and sealing. When it rains, rainwater contacts the window sash 2 and is guided by the water retaining strip 7 to flow to the water guide 26 on one side of the window frame 1. The water guide trough 26 collects the rainwater and guides it to the drainage mechanism at the bottom end of the inner wall of the window frame 1. The drainage mechanism discharges the rainwater outdoors to prevent rainwater from accumulating around the window.

[0034] The wide-angle opening of the flip-type energy-saving window enhances functionality, facilitating cleaning and flexible ventilation. It also enhances sealing performance to achieve excellent sound insulation, waterproofing, and energy-saving effects. Locking and drainage functions ensure safe use, comprehensively optimizing the practical functions of windows in buildings and resolving the functional deficiencies of traditional windows.

[0035] Please see the attached Figure 2 -Attached Figure 3 , Attachment Figure 5 The opening and closing mechanism includes two fixed blocks 10. The outer wall of the fixed block 10 is arranged in the slide groove 6 of the window frame 1. The upper surface of the fixed block 10 is provided with a rotating shaft 6. The top of the rotating shaft 6 is provided with a connecting plate 9. One end of the connecting plate 9 is provided with a rotating shaft 7. The top of the rotating shaft 7 passes through the sound insulation strip 11 and is arranged in the middle of the bottom end of the window sash 2. A slider 12 is slidably connected in the slide groove 6 of the window frame 1. The top of the slider 12 is provided with a rotating shaft 8. The top of the rotating shaft 8 passes through the sound insulation strip 11 and is arranged on one side of the middle of the bottom end of the window sash 2.

[0036] Specifically, the outer wall of the fixed block 10 is placed in the chute 6 of the window frame 1. The fixed block 10 is connected to the connecting plate 9 via a rotating shaft 6 on the upper surface. The rotating shaft 7 at one end of the connecting plate 9 passes through the sound insulation strip 11 and is connected to the middle of the bottom end of the window sash 2, providing a rotation support point for the window sash 2. The slider 12 in the chute 6 of the window frame 1 can slide in the chute 6. The rotating shaft 8 at the top of the slider 12 passes through the sound insulation strip 11 and is connected to one side of the middle of the bottom end of the window sash 2, providing another rotation support point for the window sash 2. When an external force is applied to the window sash 2, the window sash 2 is pushed by the push handle 3, and the fixed block 10 rotates in the chute 6. The connecting plate 9 is then linked to it, and the slider 12 slides and rotates accordingly in the chute 6. With the help of these two support points and the coordinated movement of their related components, the relative position and angle of the window sash 2 and the window frame 1 are changed, thereby realizing the flipping, opening or closing action of the window sash 2.

[0037] By flipping the window sash 2 relative to the window frame 1, the window sash 2 can be opened at a larger angle, making it easier to clean and maintain the inside and outside of the window. The opening angle of the window sash 2 can also be adjusted according to actual needs to meet usage requirements, solving the problem of limited opening angles of traditional windows.

[0038] Please see the attached Figure 6 -Attached Figure 8 The opening and closing mechanism also includes two fixed plates 15, and a second slide groove 19 is provided inside the fixed plate 15. The shape of the second slide groove 19 is Y-shaped. A rotating shaft 3 21 is slidably connected in the second slide groove 19 of the fixed plate 15. The outer wall of the rotating shaft 3 21 is provided with a Z-shaped rod 20. The Z-shaped rod 20 is provided on one side of the fixed plate 15. A rotating shaft 2 16 is provided at one end of the Z-shaped rod 20. Both ends of the rotating shaft 2 16 are slidably connected in the second slide groove 19 through the fixed plate 15. A connecting rod 1 22 is provided at one end of the connecting rod 1 22. A rotating shaft 4 23 is provided at one end of the rotating shaft 4 23. A connecting rod 24 is provided on the outer wall of the rotating shaft 4 23. A rotating shaft 5 25 is provided at one end of the connecting rod 24. One end of the rotating shaft 5 25 passes through the Z-shaped rod 20 and is provided with a rotating block 17 on the window frame 1.

[0039] Specifically, a Y-shaped slide groove 2 19 is provided inside the two fixed plates 15, and a rotating shaft 3 21 is slidably connected to the slide groove 2 19, and the Z-shaped rod 20 on its outer wall can move within a certain range. The two ends of the rotating shaft 2 16 at one end of the Z-shaped rod 20 are also slidably connected to the slide groove 2 19 through the fixed plate 15. When the rotating block 17 is operated, the rotating block 17 drives the rotating shaft 5 25 to rotate, thereby causing the connected connecting rod 2 24 to generate a linkage around the rotating shaft 4 23. The connecting rod 2 24 is connected to the connecting rod 1 22 through the rotating shaft 4 23, and the connecting rod 1 22 then drives the Z-shaped rod 20 to move on one side of the fixed plate 15 through the rotating shaft 2 16. Since the rotating shaft 3 21 slides in the Y-shaped slide groove 2 19, it will cooperate with the movement of the Z-shaped rod 20 to change the relative positions and angles of the various components. Through the mutual cooperation between the various components, the window sash 2 connected to the opening and closing mechanism is driven to change the relative position of the window sash 2 and the window frame 1, thereby realizing the flipping, opening or closing action of the window sash 2.

[0040] The specific structure of the opening and closing mechanism enables angle control of the window sash 2, increases the angle range of the window sash 2, enhances the flexibility of window opening operation, and can meet diverse needs such as ventilation, lighting, and external operation. This solves the problem that traditional windows can only achieve simple and limited angle opening.

[0041] Please see the attached Figure 1 -Attached Figure 2 , Attachment Figure 4 The locking mechanism includes a rotating shaft 13, one end of which is set on the outer wall of the window frame 1, and the other end of the rotating shaft 13 is provided with a handle 4. A clamping plate 14 is provided on one side of the handle 4. A clamping block 5 is provided on one side of the middle part of the window sash 2, and a clamping slot 8 is provided at one end of the clamping block 5. The outer wall of the clamping plate 14 is set inside the clamping slot 8 through the clamping block 5.

[0042] Specifically, one end of a rotating shaft 13 is fixed to the outer wall of the window frame 1, and the other end is connected to a handle 4, allowing the handle 4 to rotate about the rotating shaft 13. A clamping plate 14 is provided on one side of the handle 4, and a clamping block 5 is provided on one side of the middle portion of the window sash 2, with a clamping slot 8 on the clamping block 5. When the window sash 2 needs to be locked, the handle 4 is rotated, which drives the clamping plate 14 to rotate, so that the outer wall of the clamping plate 14 aligns with the clamping slot 8 of the clamping block 5. The engagement of the clamping plate 14 with the clamping slot 8 restricts the movement of the window sash 2 relative to the window frame 1, thereby locking the window sash 2. When unlocking is required, the handle 4 is rotated in the opposite direction, driving the clamping plate 14 to disengage from the clamping slot 8, releasing the restriction on the window sash 2 and allowing the window sash 2 to move.

[0043] The locking and unlocking functions of the window sash 2 effectively secure the position of the window sash 2, ensuring stability in the closed state, maintaining the window's tightness, and guaranteeing the independence of the indoor environment and safety. This solves the problem of traditional window locking being unreliable and prone to accidental opening.

[0044] Please see the attached Figure 6 -Attached Figure 7 The locking mechanism also includes a second card plate 29, one side of which is arranged at one end of the first card plate 14, and the outer wall of the second card plate 29 is engaged with the card slot 8 of the card block 5.

[0045] Specifically, one side of the second clamping plate 29 is connected to one end of the first clamping plate 14. When the window sash 2 is locked, the handle 4 is rotated, which drives the first clamping plate 14 to rotate. The first clamping plate 14 moves toward the slot 8 of the block 5 and is locked into the slot 8. The second clamping plate 29 connected to the first clamping plate 14 also moves accordingly, and its outer wall is also aligned with the slot 8 of the block 5 and embedded therein. Through the simultaneous engagement of the first clamping plate 14 and the second clamping plate 29 with the slot 8, the movement of the window sash 2 relative to the window frame 1 is further restricted, and the locking stability of the window sash 2 is enhanced. When unlocking, the handle 4 is rotated in the opposite direction, and the first clamping plate 14 and the second clamping plate 29 will simultaneously disengage from the slot 8, releasing the restriction on the window sash 2 and allowing it to move freely.

[0046] Please see the attached Figure 9 The drainage mechanism includes a water collecting trough 27, which is arranged at the bottom end of the inner wall of the window frame 1. The inner wall of the water collecting trough 27 is funnel-shaped, and a plurality of drainage holes 28 are provided at the bottom end of the outer wall of the window frame 1. The drainage holes 28 are connected to the water collecting trough 27. A dustproof strip 18 is provided at the bottom end of the inner wall of the window frame 1. The shape of the dustproof strip 18 is a long rectangular strip, and one side of the dustproof strip 18 is provided above the water collecting trough 27.

[0047] Specifically, when rainwater enters window frame 1, it flows toward the bottom of the inner wall of window frame 1 due to gravity. The funnel-shaped inner wall of water collecting trough 27 guides the rainwater toward its bottom. The collected rainwater is then discharged outside window frame 1 through drain hole 28 connected to water collecting trough 27. Dustproof strip 18 is positioned above water collecting trough 27 to prevent dust from directly falling into water collecting trough 27, reducing the risk of drain hole 28 becoming clogged and ensuring a smooth drainage path.

[0048] The funnel-shaped structure of the water collection trough 27 collects rainwater and drains it through the drainage holes 28, effectively draining the accumulated water in the window frame 1. Furthermore, the dust strip 18 reduces the impact of dust on the drainage system, extending its service life and ensuring long-term stability of the drainage function. This solves the problem of poor drainage in traditional window frames 1, which causes rainwater accumulation and corrosion and leakage.

[0049] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
