A type of hollow aluminum alloy window with self-locking built-in Venetian blinds

Abstract

This invention discloses a self-locking, built-in Venetian blind hollow aluminum alloy window, relating to the field of aluminum alloy window technology. It includes two parallel panes of glass, with an aluminum alloy frame installed between them. Venetian blinds are mounted on the frame. A guide rail is provided on the frame, and an internal controller for controlling the opening and closing of the Venetian blinds is slidably installed within the guide rail. The internal controller has a locked position within the guide rail. This invention controls the opening and closing of the Venetian blinds through the internal controller. When the internal controller is in the locked position, the Venetian blinds are fully retracted. Before transporting the hollow aluminum alloy window with built-in Venetian blinds, only the internal controller needs to be adjusted to the locked position. Because the internal controller is locked, even with significant external bumps, the Venetian blinds will not open, thus avoiding friction between the blind slats and the inner surface of the glass, as well as scratches between the slats, during transportation.

Description

Technical Field

[0001] This invention relates to the field of aluminum alloy window technology, specifically to a hollow aluminum alloy window with a self-locking built-in venetian blind. Background Technology

[0002] The built-in Venetian blind hollow aluminum alloy window includes an aluminum alloy frame and double-glazed glass. The aluminum alloy frame and double-glazed glass are sealed around the perimeter, forming a hollow cavity between the double-glazed glass. Venetian blinds and an internal controller for controlling the opening and closing of the Venetian blinds are installed in the cavity.

[0003] For example, Chinese utility model patent CN208564406U discloses an improved magnetic handle hollow built-in venetian blind glass, including a double glass window with a hollow section inside. Venetian blinds are installed in the hollow section, and adjusting rods are driven to both ends of the venetian blinds. Inner magnets are installed on the adjusting rods. A magnetic handle that is magnetically connected to the inner magnets is installed on the outer end face of the double glass window. A handle guide rail that slides with the magnetic handle is installed on the double glass window. The magnetic handle includes an aluminum alloy magnetic body that cooperates with the inner magnets, and a plastic shell is installed on the outside of the aluminum alloy magnetic body.

[0004] In existing technologies, including the aforementioned patent, hollow aluminum alloy windows with built-in Venetian blinds have a mutual driving relationship between the Venetian blinds and the internal controller. That is, when the internal controller moves, it will cause the Venetian blinds to open and close. When the Venetian blinds open and close under the action of gravity and other external forces, it will also cause the internal controller to move. This leads to a problem: when transporting hollow aluminum alloy windows with built-in Venetian blinds, due to bumps during transportation, the Venetian blinds will move irregularly in the hollow cavity. The slats will rub against the inner surface of the glass, and adjacent slats will also scratch each other, resulting in scratches on the slats and the glass surface. Summary of the Invention

[0005] The purpose of this invention is to provide a hollow aluminum alloy window with a self-locking built-in venetian blind to overcome the above-mentioned shortcomings of the prior art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a hollow aluminum alloy window with a self-locking built-in Venetian blind, comprising two parallel pieces of glass forming a hollow cavity between them, an aluminum alloy frame installed between the two pieces of glass, the frame being fixedly connected to the two pieces of glass by sealant, and Venetian blinds installed on the frame; a guide rail is provided on the frame, and an internal controller for controlling the opening and closing of the Venetian blinds is slidably installed within the guide rail, the internal controller having a locking position within the guide rail; when the internal controller is in the locked position, the Venetian blinds are in the closed state.

[0007] As a preferred embodiment of the present invention, it further includes an external controller located outside the hollow cavity. The external controller and the internal controller are magnetically attracted to each other, so that the external controller can drive the internal controller to move synchronously within the guide rail as the external controller moves along the guide rail.

[0008] As a preferred embodiment of the present invention, the inner controller is rotatably mounted with rollers on its surface.

[0009] As a preferred embodiment of the present invention, an iron plate is fixedly installed in the guide rail at the corresponding locking position, and a magnet plate corresponding to the position of the iron plate is fixedly installed on the inner controller.

[0010] As a preferred embodiment of the present invention, the internal controller includes a sliding seat slidably mounted on a guide rail, a locking block movably mounted on the sliding seat, and a locking pin fixedly mounted on the guide rail to cooperate with the locking block; the locking block has a first state corresponding to the position of the locking pin and a second state offset from the position of the locking pin.

[0011] As a preferred embodiment of the present invention, the locking block is rotatably connected to the sliding seat, and the sliding seat is provided with a storage groove for storing the locking block.

[0012] As a preferred embodiment of the present invention, the sliding seat is movable in the guide rail in a direction perpendicular to the glass; a push rod is slidably mounted on the sliding seat, one end of the push rod is attached to the inner surface of the glass, and the other end extends into the storage groove and is attached to the locking block; a return spring is connected between the inner wall of the storage groove and the locking block.

[0013] As a preferred embodiment of the present invention, a ball bearing is rotatably mounted on the top surface of the push rod.

[0014] As a preferred embodiment of the present invention, when the locking block is in the first state, its end is in contact with the inner wall of the guide rail to prevent the sliding seat from moving horizontally in a direction perpendicular to the length of the guide rail.

[0015] As a preferred embodiment of the present invention, a limiting plate is vertically fixedly installed on the guide rail by a bracket. The bottom surface of the limiting plate is in contact with the upper surface of the sliding seat, and the top surface of the limiting plate is in contact with the inner surface of the glass. The end face of the limiting plate facing the locking position of the inner controller is an arc-shaped surface.

[0016] In the above technical solution, the present invention provides a hollow aluminum alloy window with a self-locking built-in Venetian blind. The opening and closing of the Venetian blind is controlled by an internal controller. When the internal controller is in the locked position, the Venetian blind is in a fully retracted state. Before transporting the hollow aluminum alloy window with the built-in Venetian blind of the present invention, it is only necessary to adjust the internal controller to the locked position. Since the internal controller is locked, even if there is a large external bump, the Venetian blind will not open. This avoids the situation where the Venetian blind slats rub against the inner surface of the glass and the slats scratch against each other during transportation. Attached Figure Description

[0033] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0034] Example 1

[0035] See Figure 1 and Figure 2 This embodiment provides a hollow aluminum alloy window with a self-locking built-in Venetian blind, including two parallel glass panes 1, forming a hollow cavity between the two glass panes 1. An aluminum alloy frame 2 is installed between the two glass panes 1, and the frame 2 is fixedly connected to the two glass panes 1 by sealant. Venetian blinds 3 are installed on the frame 2. A guide rail 201 is provided on the frame 2, and an inner controller 4 for controlling the opening and closing of the Venetian blinds 3 is slidably installed in the guide rail 201. The inner controller 4 has a locking position in the guide rail 201. When the inner controller 4 is in the locking position, the Venetian blinds 3 are in the closed state.

[0036] See Figure 1 and Figure 2In this embodiment, the opening and closing of the Venetian blind 3 is controlled by the Venetian blind lifting cord 11, and the angle of the Venetian blind 3 slats is controlled by the angle adjustment cord 12; a fixing block 13 is installed on the frame 2, and a reversing wheel 14 is installed on the fixing block 13, with the Venetian blind lifting cord 11 attached to the reversing wheel 14; the inner controller 4 includes a rotating wheel 401, with the Venetian blind lifting cord 11 passing around and attached to the rotating wheel 401, one end of the Venetian blind lifting cord 11 fixedly connected to the fixing block 13, and the other end wound around the rotating seat 15, which is fixedly sleeved on the fiberglass shaft 16, which is rotatably mounted on the frame 2. When the fixing seat 15 and the fiberglass shaft 16 rotate, they drive the Venetian blind 3 to open and close synchronously; when the inner controller 4 moves downward within the guide rail 201, the rotating wheel 401... 1. The blinds move downwards synchronously and pull the blind lifting cord 11. When the blind lifting cord 11 moves, it drives the fixing base 15 and the fiberglass shaft 16 to rotate clockwise, and the blinds 3 retract, that is, the blinds 3 open, allowing light to enter the room. When the inner controller 4 moves upwards within the guide rail 201, the blind lifting cord 11 tends to loosen and no longer pulls the fixing base 15 and the fiberglass shaft 16. The blinds 3 can then change from a retracted state to a dispersed state under its own gravity, that is, the blinds 3 change from an open state to a closed state. During the closing process of the blinds 3, the fixing base 15 and the fiberglass shaft 16 are driven to rotate counterclockwise synchronously, and the loosened blind lifting cord 11 is rewound onto the fixing base 15. The above-mentioned method of controlling the opening and closing of the blinds 3 by the blind lifting cord 11 is existing technology.

[0037] The control method of the inner controller 4 includes, but is not limited to, electrical control. That is, a lead screw is installed on the frame 2 along the direction of the guide rail 201. The lead screw passes through the inner controller 4 through the threaded engagement. A control motor is installed on the frame 2. The control motor drives the lead screw to rotate, thereby controlling the position of the inner controller 4 on the guide rail 201. When the inner controller 4 moves to the locked position within the guide rail 201, the Venetian blind 3 is fully closed, that is, the Venetian blind 3 is in the open state. The Venetian blind 3 has a tendency to open under its own gravity, that is, to close. However, since the closing process of the Venetian blind 3 will inevitably drive the fixed seat 15 and the fiberglass shaft 16 to rotate, the rotation of the fixed seat 15 and the fiberglass shaft 16 will inevitably drive the Venetian blind lifting rope 11 to move. However, the Venetian blind lifting rope 11 is controlled by the inner controller 4 and will not move. Therefore, as long as the inner controller 4 is stationary in the locked position, the Venetian blind 3 will always be in the open state. When the Venetian blind 3 is in the open state, its blades are tightly fitted together. Even if there are bumps during transportation, the blades will not rub against the glass, and the blades will not scratch each other.

[0038] Example 2

[0039] like Figure 3 and Figure 4As shown, based on the above embodiments, in another embodiment provided by the present invention, the hollow aluminum alloy window of the self-locking built-in Venetian blinds also includes an external controller 5 located outside the hollow cavity. The external controller 5 and the internal controller 4 are magnetically attracted to each other, so that when the external controller 5 moves along the guide rail 201, it can drive the internal controller 4 to move synchronously within the guide rail 201.

[0040] Specifically, a magnet is fixedly installed on the inner controller 4, and a magnet is also fixedly installed on the outer controller 5. When the magnets on the inner controller 4 and the outer controller 5 approach each other, they will generate an attractive force. The outer controller 5 is slidably installed on the outer frame 17. The frame 2 and the two pieces of glass 1 are installed as a whole inside the outer frame 17, and glue is filled between the frame 2 and the outer frame 17 to prevent the frame 2 from wobbling horizontally during later use. When the outer controller 5 moves vertically on the outer frame 17, it will drive the inner controller 4 to move synchronously within the guide rail 201. This embodiment of the self-locking built-in Venetian blind is used in the hollow aluminum alloy window. Before transportation, the outer controller 5 is manually moved to the corresponding locking position of the inner controller 4. The outer controller 5 will then move the inner controller 4 to the locking position. The outer controller 5 is then manually attached to the glass 1 with tape to ensure that the outer controller 5 does not move relative to the glass 1 during transportation. This ensures that the inner controller 4 remains in the locking position during transportation, thus ensuring that the Venetian blinds 3 are always in the closed / open state. In daily use, the user can use the outer controller 5 to limit the inner controller 4 to any position within the guide rail 201, thereby controlling the opening and closing degree of the Venetian blinds 3.

[0041] like Figure 3 As shown, in this embodiment, a roller 10 is rotatably mounted on the surface of the inner controller 4; when the outer controller 5 drives the inner controller 4 to move along the guide rail 201, the inner controller 4 adheres to the surface of the glass 1 under the action of magnetic force; the roller 10 will reduce the friction between the inner controller 4 and the glass 1, ensuring that the inner controller 4 can smoothly follow the movement of the outer controller 5.

[0042] Example 3

[0043] like Figure 5 and Figure 6 As shown, in another embodiment of the present invention, based on the above embodiments, an iron plate 6 is fixedly installed in the guide rail 201 at the corresponding locking position, and a magnet plate 7 corresponding to the position of the iron plate 6 is fixedly installed on the inner controller 4.

[0044] In Embodiment 2, during the transportation of the self-locking built-in Venetian blind hollow aluminum alloy window, the external controller 5 needs to be attached to the glass 1. Although this method can ensure that the internal controller 4 is in the locked position, there are actually two problems. First, because the external controller 5 is located on the glass 1, the overall thickness of the product will increase, that is, the space occupied by a single product will increase, which is not conducive to transportation efficiency. Second, the external controller 5 attached to the glass 1 is prone to being lost due to human error.

[0045] In this embodiment, when the inner controller 4 is in the locked position, the magnet 7 and the iron plate 6 attract each other, keeping the inner controller 4 in the locked position. Therefore, it is not necessary to attach the outer controller 5 to the glass 1. During transportation, the outer controllers 5 of multiple products can be collected together and placed in a storage box, which reduces the space occupied by a single product and avoids the possibility of the outer controller 5 being easily lost. After the window is transported to the designated location and installed, the inner controller 4 can be released from the locked position by manually moving the outer controller 5 to overcome the attraction of the magnet 7 and the iron plate 6.

[0046] Example 4

[0047] like Figure 7 and Figure 8 As shown, based on Embodiment 2, this embodiment provides another preferred solution: the internal controller 4 includes a sliding seat 402 slidably mounted on the guide rail 201, a locking block 403 movably mounted on the sliding seat 402, and a locking pin 8 that cooperates with the locking block 403 fixedly mounted on the guide rail 201; the locking block 403 has a first state corresponding to the position of the locking pin 8 and a second state offset from the position of the locking pin 8.

[0048] In this embodiment, after the inner controller 4 is moved to the locked position by the outer controller 5, the Venetian blind 3 is in the open state, that is, the slats of the Venetian blind 3 are closed together. At this time, the outer controller 5 can be removed and stored separately, and the locking block 403 enters the first state. During transportation, even if the Venetian blind 3 tends to open due to large external bumps, the Venetian blind 3 will remain closed and cannot open because the inner controller 4 is limited to the locked position by the locking pin 8. When the locking block 403 changes from the first state to the second state, the locking block 403 separates from the locking pin 8, and the inner controller 4 is no longer limited by the locking pin 8. The inner controller 4 can move freely within the guide rail 201. After the window is installed as a whole, the inner controller 4 can follow the outer controller 5 to move along the guide rail 201 to control the opening and closing state of the Venetian blind 3.

[0049] The locking block 403 and the sliding seat 402 can be coupled in ways including but not limited to sliding and rotating connections; the locking block 403 can be controlled in ways including but not limited to electric control; such as Figure 9 As shown, in this embodiment, the locking block 403 is rotatably connected to the sliding seat 402, and the sliding seat 402 is provided with a storage groove 404 for storing the locking block 403; the sliding seat 402 can move in the guide rail 201 in a direction perpendicular to the glass 1; a push rod 405 is slidably mounted on the sliding seat 402, one end of the push rod 405 is attached to the inner surface of one of the glass pieces 1, and the other end of the sliding seat 402 extends into the storage groove 404 and is attached to the locking block 403; a return spring 406 is connected between the inner wall of the storage groove 404 and the locking block 403; a ball bearing 407 is rotatably mounted on the top surface of the push rod 405.

[0050] like Figure 9As shown, before transporting the self-locking built-in Venetian blinds in a hollow aluminum alloy window, the window is in a horizontal position. The inner controller 4 is located within the guide rail 201 but is not in the locked position. The locking block 403 is in the first state, and the ball bearing 407 at the top of the push rod 405 is attached to the inner surface of the upper glass 1. In this state, the outer controller 5 is manually attached to the outer surface of the upper glass 1 and aligned with the position of the inner controller 4. At this time, a suction force is generated between the sliding seat 402 and the outer controller 5. The outer controller 5 is manually operated to move along the guide rail 201 toward the locked position of the inner controller 4. The outer controller 5 will drive the inner controller 4 to move synchronously toward the locked position. The venetian blind pull cord 11 is pulled by the inner controller 4, and the venetian blind 3 gradually closes in sync. Before the inner controller 4 moves to the locking position, as the inner controller 4 moves along the guide rail 201 toward the locking position, the sliding seat 402 will drive the locking block 403 and the return spring 406 to move toward the inner surface of the upper glass 1 under the action of magnetic force, until the roller 10 on the sliding seat 402 is in contact with the inner surface of the upper glass 1. As the sliding seat 402 drives the locking block 403 and the return spring 406 toward the upper glass 1, the locking block 403 will apply an upward force to the push rod 405, but due to the top of the push rod 405... Since the ball bearing 407 is already attached to the surface of the upper glass 1 and cannot move further upward, the reaction force of the push rod 405 will push the locking block 403 to rotate. The return spring 406 is compressed by the locking block 403, causing deformation and storing energy. During the rotation of the locking block 403, it transitions from the first state to the second state. As the outer controller 5 drives the inner controller 4 to move to the locking position, the locking block 403 passes the locking pin 8 in the second state and reaches the side of the locking pin 8 facing the locking position. After the inner controller 4 moves to the locking position, the outer controller 5 is manually removed, the magnetic force between the outer controller 5 and the inner controller 4 disappears, and the inner controller 4 is no longer subject to external attraction. In this process, the sliding seat 402 will detach from the surface of the upper glass 1 and fall onto the bottom surface of the guide rail 201 under its own gravity. During this process, the compressed and deformed return spring 406 gradually recovers and pushes the locking block 403 to reverse until the locking block 403 reverses from the second state to the first state. At this time, the inner controller 4 is in the locked position, and the locking block 403 returns to the first state. The locking block 403 in the first state is blocked by the locking pin 8 and cannot move to the side away from the locked position. That is, the cooperation between the locking block 403 and the locking pin 8 makes the inner controller 4 self-lock in the locked position, thereby ensuring that the Venetian blinds 3 are always in the closed state during transportation.

[0051] In Embodiment 3, the inner controller 4 is self-locked by the magnetic attraction of the magnet 7 and the iron plate 6. Unlocking the inner controller 4 requires overcoming the magnetic force of the magnet 7 and the iron plate 6 by its own magnetic attraction with the outer controller 5. In actual operation, the outer controller 5 may be unable to drive the inner controller 4 out of the locked position. In this embodiment, the inner controller 4 is self-locked by the cooperation of the locking block 403 and the locking pin 8, ensuring that the outer controller 5 can smoothly drive the inner controller 4 out of the locked position. In this embodiment, the outer controller 5 plays the role of driving the inner controller 4 to move along the guide rail 201, and also controls the state of the locking block 403 by driving the inner controller 4 to move in a direction perpendicular to the guide rail 201 and the glass 1.

[0052] In this embodiment, when the locking block 403 is in the first state, its end is in contact with the inner wall of the guide rail 201 to prevent the sliding seat 402 from moving horizontally in a direction perpendicular to the length of the guide rail 201; a limiting plate 9 is vertically fixedly installed on the guide rail 201 by a bracket, the bottom surface of the limiting plate 9 is in contact with the upper surface of the sliding seat 402, and the top surface of the limiting plate 9 is in contact with the inner surface of the glass 1; the end face of the limiting plate 9 facing the locking position of the inner controller 4 is an arc-shaped surface.

[0053] In this embodiment, when the locking block 403 is in the first state, it can not only cooperate with the locking pin 8 to play a self-locking role for the inner controller 4 as a whole during transportation, but also prevent the inner controller 4 from swaying horizontally in the direction perpendicular to the guide rail 201 within the guide rail 201. This ensures that the inner controller 4 is aligned with the outer controller 5 during daily use, thereby ensuring that the movement of the outer controller 5 can drive the inner controller 4 to move synchronously and smoothly. Specifically, when the locking block 403 is in the first state, its end is in contact with the inner sidewall of the guide rail 201. Since the return spring 406 supports the locking block 403, the locking block 403 will not easily rotate under the action of external force. Therefore, the inner controller 4 will not sway horizontally in the direction perpendicular to the guide rail 201 under the positioning action of the locking block 403.

[0054] Before transporting the window, the window is in a horizontal position. The user moves the inner controller 4 to the locking position using the outer controller 5. During this process, the limiting plate 9 limits the sliding seat 402. That is, although the inner controller 4 moves synchronously with the outer controller 5 under the suction of the outer controller 5, the inner controller 4 is blocked by the limiting plate 9 and does not adhere to the inner surface of the glass 1, but rather adheres to the inner wall of the guide rail 201, i.e., the locking block 403 remains in the first state. When the sliding seat 402 slides to the position where it separates from the limiting plate 9, the locking block 403 also moves synchronously with the sliding seat 402 to the position close to the locking pin 8, and the locking block 403 is located on the side of the locking pin 8 away from the locking position. Due to the limiting... Plate 9 no longer limits the sliding seat 402, so the sliding seat 402 can move towards the glass 1 under the suction of the external controller 5 until the roller 10 on the sliding seat 402 is in contact with the inner surface of the glass 1. The locking block 403 also changes from the first state to the second state simultaneously, and the return spring 406 is compressed and deformed and stores energy. As the external controller 5 continues to move towards the locking position, the sliding seat 402, under the suction, drives the locking block 403 in the second state to pass through the locking pin 8 and reach the locking position. It should be noted that this displacement of the sliding seat 402 is very short, only slightly larger than the diameter of the locking pin 8. Finally, the external controller 5 is removed, and the gravity of the internal controller 4 and the return spring 406... The rebound force causes the inner controller 4 to separate from the glass 1 until the sliding seat 402 returns to a state of contact with the inner surface of the guide rail 201. The locking block 403 then transitions from the second state to the first state and engages with the locking pin 8, thus locking the inner controller 4 in the locked position. During window transportation and installation, the inner controller 4 remains in the locked position. After the window is installed, the inner controller 4 and the outer controller 5 are positioned correctly, creating a suction force between them. The inner controller 4 will engage with the glass 1 under this suction, and the locking block 403 will transition from the first state to the second state at the locked position. The locking pin 8 no longer locks the inner controller 4. At this point, the position of the outer controller 5 can be manually adjusted. The position of the inner controller 4 is adjusted to regulate the opening and closing degree of the Venetian blinds 3. It should be noted that after the window is installed and is in a vertical position, as the outer controller 5 drives the inner controller 4 to move upward along the guide rail 201 from the locked state, the inner controller 4 will come into contact with the end face of the limiting plate 9 facing the locked position, and under the reaction force of the limiting plate 9, it will separate from the glass 1. The locking block 403 will simultaneously change from the second state to the first state. In the first state, the locking block 403 plays a positioning role for the inner controller 4, preventing the inner controller 4 from swaying horizontally in the direction perpendicular to the guide rail 201. In summary, as long as the inner controller 4 is in the position corresponding to the limiting plate 9, it will not sway.

[0055] Example 5

[0056] like Figure 10 and Figure 11 As shown, this embodiment is similar to embodiment four in that: the inner controller 4 includes a sliding seat 402 slidably mounted on the guide rail 201, a locking block 403 is movably mounted on the sliding seat 402, and a locking pin 8 that cooperates with the locking block 403 is fixedly mounted on the guide rail 201; the locking block 403 has a first state corresponding to the position of the locking pin 8 and a second state offset from the position of the locking pin 8; when the locking block 403 is in the first state, its end is in contact with the inner sidewall of the guide rail 201 to prevent the sliding seat 402 from moving horizontally in a direction perpendicular to the length of the guide rail 201; a limiting plate 9 is vertically fixedly mounted on the guide rail 201 by a bracket, the bottom surface of the limiting plate 9 is in contact with the upper surface of the sliding seat 402, and the top surface of the limiting plate 9 is in contact with the inner surface of the glass 1; the end face of the limiting plate 9 facing the locking position of the inner controller 4 is an arc-shaped surface.

[0057] The difference between this embodiment and embodiment four is that: the locking block 403 is slidably mounted on the sliding seat 402; a groove 408 is provided on the surface of the sliding seat 402, and an adjusting block 409 is slidably mounted in the groove 408 in a direction perpendicular to the glass 1 and the guide rail 201; a support spring 410 is connected between the adjusting block 409 and the sliding seat 402; an inclined adjusting groove 411 is provided on the adjusting block 409, and a protrusion is provided on the locking block 403 that slides with the adjusting groove 411; a roller 10 is rotatably mounted on the adjusting block 409.

[0058] When the inner controller 4 is located within the guide rail 201 and within the range corresponding to the limiting plate 9, the locking block 403 is in the first state. The support spring 410 supports the adjusting block 409, keeping the position of the adjusting block 409 unchanged within the slide groove 408, thus allowing the locking block 403 to remain in the first state. The outer controller 5 drives the inner controller 4 to move along the guide rail 201 towards the locking position. After the inner controller 4 leaves the range corresponding to the limiting plate 9, the attraction between the outer controller 5 and the sliding seat 402 causes the sliding seat 402, support spring 410, adjusting block 409, and locking block 403 to move synchronously towards the outer controller 5. During this process, the roller 10 on the adjusting block 409 first contacts the surface of the glass 1, preventing the adjusting block 409 and its roller 10 from moving further towards the outer controller 5. However, the sliding seat 402 and its locking block 403 can still move towards the outer controller 5, creating a connection between the sliding seat 402 and the adjusting block 409. During relative displacement, the support spring 410 is compressed and stores energy; during the relative movement of the sliding seat 402 and the adjusting block 409, the adjusting groove 411 guides the locking block 403, causing the locking block 403 to retract into the sliding seat 402, that is, the locking block 403 changes from the first state to the second state; as the external controller 5 continues to move toward the locking position, the sliding seat 402, under the action of suction, drives the locking block 403 in the second state to pass through the locking pin 8 and reach the locking position; during the transportation of the window, after the internal controller 4 is adjusted to the locking position by the external controller 5, the external controller 5 is removed, and the gravity of the sliding seat 402 itself and the rebound force of the support spring 410 cause the internal controller 4 to separate from the glass 1. During the reset process of the support spring 410, the relative position of the sliding seat 402 and the adjusting block 409 is restored, thereby driving the locking block 403 from the second state back to the first state through the adjusting groove 411. The locking block 403 cooperates with the locking pin 8 to lock the internal controller 4 in the locking position.

[0059] It should be noted that, similar to Embodiment 4, in this embodiment, the external controller 5 serves two purposes: firstly, it drives the internal controller 4 to move along the guide rail 201; secondly, by driving the internal controller 4 to move in a direction perpendicular to the guide rail 201 and the glass 1, it controls the state of the locking block 403. The locking block 403, in conjunction with the locking pin 8, acts as a self-locking mechanism for the internal controller 4 during window transportation; and thirdly, during normal use, the locking block 403, in conjunction with the limiting plate 9, positions the internal controller 4, preventing it from wobbling within the guide rail 201 and ensuring that the external controller 5 can drive the internal controller 4 to move smoothly and synchronously.

[0060] Example 6

[0061] like Figure 12 and Figure 13As shown, based on Embodiment 5, this embodiment provides a preferred solution: a groove 202 is provided on the inner surface of the guide rail 201 at the locking position; a top support magnet 203 is slidably installed in the groove 202 in a direction perpendicular to the glass 1; a top support spring 204 is connected between the top support magnet 203 and the inner wall of the groove 202; a top support rod 412 is rotatably installed on the sliding seat 402; a torsion spring is connected between the top support rod 412 and the sliding seat 402; the top support rod 412 is in a horizontal state when not in contact with the top support magnet 203, and in a vertical state when in contact with the top support magnet 203; when the external controller 5 drives the internal controller 4 to the locking position, a repulsive magnetic force is generated between the external controller 5 and the top support magnet 203, and the top support magnet 203 compresses the top support spring 204 under the action of this force. The outer controller 5 moves into the groove 202. After the outer controller 5 is removed, the top support spring 204 resets and pushes the top support magnet 203 out of the groove 202. At the same time, the inner controller 4, which loses the attraction of the outer controller 5, also separates from the surface of the glass 1 and falls onto the inner surface of the groove 202. During this process, the top support rod 412, which was originally in a horizontal state, comes into contact with the top support magnet 203 and is pushed by the reaction force of the top support magnet 203, and finally becomes vertical. The top support rod 412 in the vertical state limits the distance between the adjusting block 409 and the sliding seat 402, so as to prevent the adjusting block 409 and the sliding seat 402 from getting close to each other due to the large external bumps during transportation, which would cause the locking block 403 to change from the first state to the second state. This further ensures that the inner controller 4 can lock itself in the locked position during transportation.

[0062] Specifically, during the process of the inner controller 4 moving along the guide rail 201 to the locking position driven by the outer controller 5, before the locking block 403 contacts the locking pin 8, the inner controller 4 moves towards the outer controller 5 under the magnetic force of the outer controller 5 and adheres to the glass 1, and the locking block 403 changes from the first state to the second state; when the outer controller 5 drives the inner controller 4 to the locking position along the guide rail 201, a repulsive magnetic force is generated between the top support magnetic block 203 and the outer controller 5, and the top support magnetic block 203, which was originally protruding from the groove 202, enters the groove 202 under the action of this force; after the outer controller 5 is removed, the top support magnetic block 203 moves out of the groove 202, and at the same time the inner controller 4... It also separates from the surface of glass 1 and falls onto the inner surface of the groove 202. The locking block 403 changes from the second state to the first state. The top support rod 412, which was originally horizontal, contacts the top support magnet 203 that has moved out of the groove 202, and under the reaction force of the top support magnet 203, it overcomes the torsion spring and rotates to the vertical state. During the transportation of the window, even if the window is subjected to great external bumps, due to the limiting effect of the top support rod 412, the vertical relative displacement between the adjusting block 409 and the sliding seat 402 is very small, which is not enough to make the locking block 403 change from the first state to the second state, thus ensuring that the inner controller 4 can self-lock in the locked position.

[0063] When it is necessary to remove the inner controller 4 from the locked position, simply attach the outer controller 5 to the outer surface of the glass 1 at the position corresponding to the inner controller 4. Under the magnetic force of the outer controller 5, the top support magnet 203 enters the groove 202, and the top support rod 412 is reversed and restored to the horizontal state under the action of the torsion spring. That is, the top support rod 412 no longer restricts the distance between the adjusting block 409 and the sliding seat 402, and the adjusting block 409 and the sliding seat 402 can generate a vertical relative displacement so that the locking block 403 changes from the first state to the second state. Finally, the inner controller 4 can be removed from the locked position by the outer controller 5.

[0064] It should be noted that in this embodiment, when the external controller 5 is close to the internal controller 4, a magnetic force will be generated that attracts each other, and when the external controller 5 is close to the top support magnetic block 203, a magnetic force will be generated that repels each other; and the coverage area of ​​the magnet on the external controller 5 is larger than the coverage area of ​​the magnet on the internal controller 4, so that the external controller 5 can generate magnetic force with both the internal controller 4 and the top support magnetic block 203 at the same time.

[0065] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.

Claims

1. A hollow aluminum alloy window with self-locking built-in Venetian blinds, comprising two parallel panes of glass forming a hollow cavity between them, an aluminum alloy frame installed between the two panes of glass, the frame being fixedly connected to the two panes of glass by sealant, and Venetian blinds installed on the frame, characterized in that... The frame is provided with a guide rail, and an inner controller for controlling the opening and closing of the Venetian blinds is slidably installed in the guide rail. The inner controller has a locked position in the guide rail; when the inner controller is in the locked position, the Venetian blinds are in the closed state. The self-locking built-in venetian blind hollow aluminum alloy window also includes an external controller located outside the hollow cavity. The external controller and the internal controller are magnetically attracted to each other, so that when the external controller moves along the guide rail, it can drive the internal controller to move synchronously within the guide rail. The internal controller includes a sliding seat slidably mounted on a guide rail, a locking block rotatably mounted on the sliding seat, and a locking pin fixedly mounted on the guide rail that cooperates with the locking block. The locking block has a first state corresponding to the position of the locking pin and a second state offset from the position of the locking pin. The sliding seat has a storage groove for storing the locking block. The sliding seat can move within the guide rail in a direction perpendicular to the glass. A push rod is slidably mounted on the sliding seat, with one end of the push rod abutting the inner surface of the glass and the other end extending into the storage groove and abutting the locking block. A return spring is connected between the inner wall of the storage groove and the locking block. When the locking block is in the first state, its end abuts against the inner wall of the guide rail to prevent the sliding seat from moving horizontally in a direction perpendicular to the length of the guide rail. During the process of the external controller moving the internal controller to the locking position, the locking block passes the locking pin in the second state and reaches the side of the locking pin facing the locking position; the cooperation between the locking block and the locking pin makes the internal controller self-lock in the locking position, thereby ensuring that the Venetian blinds are always in the retracted state during transportation. An iron plate is fixedly installed at the corresponding locking position inside the guide rail, and a magnet plate corresponding to the position of the iron plate is fixedly installed on the internal controller. The outer controller is manually attached to the outer surface of the upper glass and aligned with the position of the inner controller. At this time, a suction force is generated between the sliding seat and the outer controller. As the sliding seat moves the locking block and the return spring toward the upper glass, the locking block applies an upward force to the push rod. However, since the ball bearing at the top of the push rod is already attached to the surface of the upper glass and cannot move further upward, the reaction force of the push rod will push the locking block to rotate. The return spring is compressed by the locking block, causing deformation and storing energy. During the rotation of the locking block, it transitions from the first state to the second state.

2. A hollow aluminum alloy window with a self-locking built-in Venetian blind as described in claim 1, characterized in that, The internal controller is rotatably mounted with rollers on its surface.

3. A hollow aluminum alloy window with a self-locking built-in Venetian blind as described in claim 2, characterized in that, The top surface of the push rod is rotatably fitted with ball bearings.

4. A hollow aluminum alloy window with a self-locking built-in Venetian blind as described in claim 3, characterized in that, A limiting plate is vertically fixed on the guide rail by a bracket. The bottom surface of the limiting plate is in contact with the upper surface of the sliding seat, and the top surface of the limiting plate is in contact with the inner surface of the glass. The end face of the limit plate facing the locking position of the inner controller is an arc-shaped surface.
