Description

Technical Field

[0001] The invention relates to a composite door and window, in particular to an energy-saving self-locking composite door and window. Background Art

[0002] Doors and windows are an integral part of architectural design. They provide insulation, heat insulation, sound insulation, waterproofing, and fire protection. Furthermore, they must ensure ventilation within the building. Therefore, to facilitate their opening and closing, corresponding opening and closing devices are required. Traditional doors and windows mostly use casement or sliding opening and closing methods.

[0003] When existing sliding doors and windows are closed, users often forget to lock them. Doors and windows are easily opened and closed frequently in windy weather, causing damage to the doors and windows and reducing the protective effect of the doors and windows. In addition, in order to improve the ventilation in the building, users sometimes open the doors and windows when going out. When it rains, the doors and windows cannot be closed, and rainwater easily enters the building, causing damage to the items inside the building, and the practicality of the doors and windows is poor. Summary of the Invention

[0004] The purpose of the present invention is to provide an energy-saving self-locking composite door and window to solve the technical problems in the prior art. It can automatically lock when the door and window are closed, avoiding damage to the door and window due to frequent opening and closing in weather such as strong winds, thereby improving the protective effect of the door and window; and on rainy days, it can automatically close the door and window to prevent damage to items in the building during rain, which is more practical.

[0005] The present invention provides an energy-saving self-locking composite door and window, comprising: an outer frame, a retaining ring is provided on the inner side of the outer frame, and a window frame is provided on the inner side of the outer frame; a self-locking mechanism is provided inside the window frame, and the self-locking mechanism is adapted to the retaining ring; a buffer mechanism, at least partially provided at the upper and lower parts of the inner side of the outer frame, and part of the buffer mechanism is rotatably connected to the window frame; a fixed block, provided at the top of the outer side of the outer frame, and a cavity is provided at the bottom of the fixed block; a self-closing mechanism, comprising a driving member and a triggering member, the driving member being provided in the cavity, the driving member being capable of driving the window frame to close, and the triggering member being provided above the driving member.

[0006] In the technical solution of the embodiment of the present application, when the window frame is closed, the self-locking mechanism and the snap ring can achieve self-locking of the window frame, preventing the user from forgetting to lock the window frame and frequently opening and closing it in windy weather or other weather conditions, thereby improving the protective effect of doors and windows; further, when it rains, the trigger member will trigger the driving member, and the window frame will automatically close through the driving member, thereby preventing rainwater from entering the building and damaging items inside the building, and the window frame will automatically lock when it is closed. This design makes the doors and windows more energy-efficient when in use, and overcomes the problem of the window frame requiring electricity when automatically closing; in addition, when the window frame is closing, the buffer mechanism will reduce the impact between the window frame and the outer frame when the window frame is about to close, further improving the stability of the window frame's automatic closing.

[0007] Preferably, the self-locking mechanism includes: a slot provided on a side of the window frame near the retaining ring; a wedge-shaped block rotatably connected to the interior of the slot; a self-locking spring having one end connected to the bottom of the wedge-shaped block and the other end connected to the bottom of the slot; and a handle provided on the exterior of the window frame, the handle being connected to the wedge-shaped block. When the window frame is closed, the wedge-shaped block rotates upon contact with the retaining ring. When the wedge-shaped block reaches the middle of the retaining ring, the wedge-shaped block returns to its initial position under the action of the self-locking spring, thereby achieving self-locking of the window frame when closed.

[0008] Preferably, the size of the slot is larger than that of the snap ring, the side of the wedge block closest to the snap ring is inclined, and the size of the wedge block matches the size of the center of the snap ring, so that the window frame can be automatically locked. This allows the wedge block to rotate within the slot when it contacts the snap ring, and when the wedge block reaches the center of the snap ring, it is more stable.

[0009] Preferably, the buffer mechanism includes: a chute symmetrically disposed at the upper and lower portions of the inner side of the outer frame; a slider disposed within the chute, the size of the slider being adapted to the size of the chute; a connecting plate rotatably connected to the slider at one end and to the window frame at the other end; and a buffer spring connected to the chute on the side of the chute closest to the retaining ring. This allows the buffer spring to slow down the closing speed of the window frame when it is about to fully close, thereby reducing the impact between the window frame and the outer frame.

[0010] Preferably, the driving member includes: a driving plate rotatably connected to the interior of the cavity; a clamping block connected to the top of the driving plate; a tension spring having one end connected to the driving plate and the other end connected to the cavity; a ratchet rod rotatably connected to the interior of the cavity; and a return spring having one end connected to the ratchet rod and the other end connected to the cavity. When the window frame is opened, the clamping block engages with the ratchet rod, which does not affect the opening of the window frame. When the ratchet rod disengages from the clamping block, the window frame can be closed by the driving plate under the action of the tension spring.

[0011] Preferably, the bottom of the locking block is arc-shaped, the top of the ratchet rod is inclined, the ratchet rod engages with the locking block, the drive plate is at least partially located outside the cavity, and the bottom of the drive plate contacts the window frame. In this way, when the window frame is opened, the ratchet rod engages with the locking block, thereby fixing the drive plate there, and the tension spring is in a stretched state, facilitating the rotation of the drive plate.

[0012] Preferably, the triggering member includes: a water collecting trough provided at the top of the fixing block; a limiting hole provided inside the fixing block, the top end of the limiting hole being connected to the water collecting trough, and the bottom end of the limiting hole being connected to the cavity; a limiting plate connected to the lower portion of the inner side of the limiting hole; a support spring connected to the top of the limiting plate; a sealing plate slidably connected to the inner side of the limiting hole, the bottom end of the sealing plate being connected to the top end of the support spring; and a push rod connected to the bottom end of the sealing plate, the push rod being slidably connected to the limiting plate. On rainy days, some rainwater will enter the limiting hole through the water collecting trough. As the amount of rainwater increases, the sealing plate is driven to move downward in the limiting hole, and the push rod is used to disengage the ratchet rod from the block, so that the driving plate can rotate under the action of the tension spring.

[0013] Preferably, the push rod is located above the ratchet rod, and the sealing plate can adjust the position of the push rod relative to the ratchet rod's inclination in the axial direction of the limiting hole, so that when the push rod moves downward in the limiting hole, the ratchet rod can be disengaged from the block.

[0014] Compared with the existing technology, the present invention can make the window frame self-locking when closed, avoiding damage to doors and windows caused by frequent opening and closing in windy weather, thereby improving the protective effect of doors and windows; and on rainy days, it can automatically close doors and windows to prevent items in the building from being damaged by rain, which is more practical; secondly, the window frame does not require electricity when it is automatically closed, which is more energy-saving.

[0033] like Figure 1-5 As shown, an embodiment of the present invention provides an energy-saving self-locking composite door and window, comprising: an outer frame 1, a retaining ring 2 is provided on the inner side of the outer frame 1, and a window frame 3 is provided on the inner side of the outer frame 1; a self-locking mechanism, arranged inside the window frame 3, and the self-locking mechanism is adapted to the retaining ring 2; a buffer mechanism, at least partially arranged at the upper and lower parts of the inner side of the outer frame 1, and part of the buffer mechanism is rotatably connected to the window frame 3; a fixed block 13, arranged at the top of the outer side of the outer frame 1, and a cavity 14 is opened at the bottom of the fixed block 13; a self-closing mechanism, comprising a driving member and a triggering member, the driving member is arranged in the cavity 14, the driving member can drive the window frame 3 to close, and the triggering member is arranged above the driving member.

[0034] In the technical solution of the embodiment of the present application, when the window frame 3 is closed, the self-locking mechanism and the snap ring 2 can realize the self-locking of the window frame 3, thereby preventing the user from forgetting to lock the window frame 3 and frequently opening and closing it in windy weather or other weather conditions, thereby improving the protective effect of doors and windows; further, when it rains, the trigger member will trigger the driving member, and the window frame 3 will be automatically closed by the driving member, thereby preventing rainwater from entering the building and damaging the items inside the building, and the window frame 3 will automatically lock when it is closed. Such a design makes the doors and windows more energy-efficient when in use, and overcomes the problem that the window frame 3 requires electricity when it is automatically closed; in addition, when the window frame 3 is closing, the buffer mechanism will reduce the impact between the window frame 3 and the outer frame 1 when the window frame 3 is about to close, thereby further improving the stability of the automatic closing of the window frame 3.

[0035] In the embodiments provided in this application, Figure 2 and Figure 5 As shown, the self-locking mechanism includes: a slot 4, which is opened on the side of the window frame 3 close to the snap ring 2; a wedge block 5, which is rotatably connected to the inside of the slot 4; a self-locking spring 6, one end of which is connected to the bottom of the wedge block 5 and the other end is connected to the bottom of the slot 4; a handle 7, which is arranged on the outside of the window frame 3 and is connected to the wedge block 5.

[0036] A glass plate 8 is provided on the inner side of the window frame 3 to ensure the light transmittance of the doors and windows. When the window frame 3 is closed, the snap ring 2 will enter the slot 4. When the snap ring 2 contacts the wedge block 5, the wedge block 5 will rotate. When the wedge block 5 moves to the middle of the snap ring 2, the wedge block 5 will rotate to the initial position under the action of the spring, thereby realizing self-locking. When the doors and windows need to be opened, the handle 7 is turned to drive the wedge block 5 to disengage from the snap ring 2. This can prevent the user from forgetting to lock the window frame 3 when closing it, making the window frame 3 more stable when closed, thereby improving the protection effect of the doors and windows.

[0037] In the embodiments provided in this application, Figure 5 and Figure 6As shown, the size of the slot 4 is larger than that of the snap ring 2, the side of the wedge block 5 close to the snap ring 2 is inclined, and the size of the wedge block 5 is adapted to the size in the middle of the snap ring 2, so that the window frame 3 can be automatically locked.

[0038] When the snap ring 2 is close to the inclined part of the wedge block 5, the wedge block 5 can be rotated in the slot 4 under the action of the inclined surface of the wedge block 5, which facilitates the engagement of the snap ring 2 and the wedge block 5. When engaged, the shaking of the wedge block 5 in the snap ring 2 can be reduced, making the window frame 3 more stable.

[0039] In the embodiments provided in this application, Figure 3-4 As shown, the buffer mechanism includes: a slide groove 9, which is symmetrically opened at the upper and lower parts of the inner side of the outer frame 1; a slider 10, which is arranged inside the slide groove 9, and the size of the slider 10 is adapted to the size of the slide groove 9; a connecting plate 11, one end of which is rotatably connected to the slider 10, and the other end of which is rotatably connected to the window frame 3; a buffer spring 12, which is connected to the side of the slide groove 9 close to the retaining ring 2.

[0040] When the window frame 3 is closed, it can drive the connecting plate 11 to rotate accordingly, driving the slider 10 to move in the slide groove 9. When the window frame 3 is about to close, the slider 10 will contact the buffer spring 12, reducing the speed of the window frame 3 when closing, thereby reducing the impact between the window frame 3 and the outer frame 1, and when opening the window frame 3, under the action of the buffer spring 12, it is easier to open the window frame 3, which is more labor-saving.

[0041] In the embodiments provided in this application, Figure 7 and Figure 8 As shown, the driving member includes: a driving plate 15, which is rotatably connected to the inside of the cavity 14; a blocking block 16, which is connected to the top of the driving plate 15; a tension spring 17, one end of which is connected to the driving plate 15 and the other end is connected to the cavity 14; a ratchet rod 18, which is rotatably connected to the inside of the cavity 14; and a return spring 19, one end of which is connected to the ratchet rod 18 and the other end is connected to the cavity 14.

[0042] When the window frame 3 is opened, the window frame 3 will drive the driving plate 15 to rotate upward in the cavity 14, so that the block 16 rotates downward at the ratchet rod 18. When the window frame 3 is opened to the maximum angle, the block 16 will engage with the ratchet rod 18, and the driving plate 15 will stay there. The window frame 3 can be adjusted at will between these angles without affecting the adjustment of the angle of the window frame 3. After the ratchet rod 18 is disengaged from the block 16, the driving plate 15 rotates downward under the action of the tension spring 17, thereby driving the window frame 3 to rotate toward the closing side, thereby achieving the closing of the window frame 3.

[0043] In the embodiments provided in this application, Figure 1 and Figure 8As shown, the bottom of the block 16 is arc-shaped, the top of the ratchet rod 18 is inclined, the ratchet rod 18 is engaged with the block 16, the drive plate 15 is at least partially located outside the cavity 14, and the bottom of the drive plate 15 is in contact with the window frame 3.

[0044] The engagement between the ratchet rod 18 and the card block 16 can be a technical solution in the existing prior art, which can be known to those skilled in the art and will not be elaborated here. When the card block 16 rotates downward on the upper side of the ratchet rod 18, the ratchet rod 18 will not affect the rotation of the card block 16, and when the card block 16 rotates to the lower side of the ratchet rod 18, the ratchet rod 18 can fix the card block 16 and the drive plate 15.

[0045] In the embodiments provided in this application, Figure 7-9 As shown, the trigger component includes: a water collecting tank 20, which is opened at the top of the fixed block 13; a limiting hole 21, which is opened inside the fixed block 13, the top of the limiting hole 21 is connected to the water collecting tank 20, and the bottom end of the limiting hole 21 is connected to the cavity 14; a limiting plate 22, which is connected to the lower part of the inner side of the limiting hole 21; a supporting spring 23, which is connected to the top of the limiting plate 22; a sealing plate 24, which is slidably connected to the inside of the limiting hole 21, and the bottom of the sealing plate 24 is connected to the top of the supporting spring 23; a push rod 25, which is connected to the bottom of the sealing plate 24, and the push rod 25 is slidably connected to the limiting plate 22.

[0046] On rainy days, some rainwater will enter the sump 20. As the amount of rainwater increases, the sealing plate 24 will be pressed downward, driving the push rod 25 to move downward. When the push rod 25 contacts the ratchet rod 18, the ratchet rod 18 will be driven to disengage from the block 16. The driving plate 15 will rotate downward under the action of the tension spring 17. At the same time, the block 16 will drive the push rod 25 to move upward. At this time, the sealing plate 24 will push out most of the rainwater in the limiting hole 21, making it easier for the next use.

[0047] In the embodiments provided in this application, Figure 9 As shown, the push rod 25 is located above the ratchet rod 18 , and the sealing plate 24 can adjust the position of the push rod 25 at an angle relative to the ratchet rod 18 in the axial direction of the limiting hole 21 .

[0048] In this way, when the push rod 25 moves downward in the limiting hole 21 , the ratchet rod 18 is disengaged from the blocking block 16 .

[0049] The method of using the present invention is as follows: when the doors and windows are closed, the slot 4 gradually rotates toward the side of the snap ring 2. When the snap ring 2 contacts the wedge block 5, it will drive the wedge block 5 to rotate in the slot 4. When the wedge block 5 moves to the middle of the snap ring 2, the wedge block 5 will rotate to the initial position under the action of the self-locking spring 6, so that the wedge block 5 reaches the middle of the snap ring 2. Under the action of the wedge block 5 and the snap ring 2, the window frame 3 can be locked, avoiding the user forgetting to lock the window frame 3. Frequent opening and closing in strong winds and other weather conditions will cause damage to the doors and windows, and at the same time reduce the protective effect of the doors and windows.

[0050] At the same time, when the window frame 3 is closed, under the action of the connecting plate 11, the slider 10 moves in the slide groove 9. When the slider 10 contacts the buffer spring 12, the speed of closing the window frame 3 can be reduced, thereby reducing the impact between the window frame 3 and the outer frame 1, and preventing the window frame 3 or the outer frame 1 from being damaged.

[0051] When the sash 3 is opened, the driving plate 15 and the card block 16 are driven to rotate. When the card block 16 rotates to the lower side of the ratchet rod 18, the ratchet rod 18 can fix the card block 16 and the driving plate 15 there, and the tension spring 17 is in a stretched state. When it rains, rainwater will enter the limiting hole 21 through the sump 20. As the rainwater increases, the sealing plate 24 is pressed downward, driving the push rod 25 to move downward. When the push rod 25 contacts the ratchet rod 18, the ratchet rod 18 is driven to disengage from the card block 16, and the driving plate 15 and the card block 16 are rotated to the initial position under the action of the tension spring 17. The card block 16 drives the push rod 25 and the sealing plate 24 to move upward in the limiting hole 21, and at the same time pushes out the rainwater in the limiting hole 21, and the driving plate 15 drives the sash 3 to rotate to the closed side, thereby realizing the automatic closing of the sash 3, preventing the articles in the building from being damaged during rainwater collection. Moreover, the sash 3 does not require electricity when automatically closing, which is more energy-saving.

[0052] The above description is only a preferred embodiment of the present invention, but the scope of implementation of the present invention is not limited to what is shown in the drawings. Any changes made in accordance with the concept of the present invention, or modifications to equivalent embodiments with equivalent changes, which do not exceed the spirit covered by the description and drawings, should be within the scope of protection of the present invention.
