Description

Technical Field

[0001] This invention belongs to the field of door and window technology, specifically relating to a screen door linked to a sealing sliding door. Background Technology

[0002] Most existing building windows and interior doors are made of profiles, namely the common sliding doors or windows. Because sliding doors and windows are installed on parallel tracks, they can only achieve a sealed state when the two or more doors or windows are completely closed. When they are partially open or partially closed, even with the use of screens, there are often large gaps between the two or more doors or windows, allowing insects and dust to easily enter the room, affecting home life and the indoor environment.

[0003] Meanwhile, in existing screen door applications, screen doors mostly rely on purely manual operation to open and close, lacking automatic linkage or anti-accidental closing designs. In daily use, users must operate the movable door and the screen door separately. Due to usage habits, carelessness, or distraction during operation, it is easy for the screen door to fail to close promptly and effectively after the movable door has opened; similarly, it fails to provide mosquito and insect protection. Therefore, these problems urgently need to be addressed. Summary of the Invention

Detailed Implementation

[0018] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0019] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0020] As mentioned in the background section, this application proposes a screen door linkage sealing sliding door, including a door frame 100, which extends through the door frame in a first direction and has a fixed door leaf 110 and a movable door leaf 200 arranged in the first direction inside; the fixed door leaf 110 is fixedly installed on the door frame 100, including a fixed door leaf frame 111 located in the middle of the door frame 100; the movable door leaf 200 is slidably installed on the door frame 100, including a movable door leaf frame 210 slidably connected to the door frame 100; and a screen door 300, which includes a sand-rolling box 310 fixedly installed on the door frame 100 and a screen mesh connected to the sand-rolling box 310. A vertical handle 320 is connected to the movable door frame 210; the sand box 310 is located at the end of the door frame 100 away from the fixed door leaf 110; the vertical handle 320 is magnetically connected to the fixed door leaf frame 111; a linkage mechanism is included, which includes a snap-fit ​​seat 400 fixedly installed on the movable door leaf frame 210 and a snap-fit ​​connector 410 movably installed on the vertical handle 320; the snap-fit ​​seat 400 is U-shaped with its opening facing vertically downward, and has inclined surfaces on both sides for guidance; the snap-fit ​​connector 410 is slidably installed on the movable door leaf frame 210 and is also connected to the movable door leaf frame 210 by a spring for automatic snap-fit ​​with the snap-fit ​​seat 400.

[0021] In this embodiment, the door frame 100 is completely through along the first direction, forming an opening for passage. Inside the door frame 100, a fixed panel 110 and a movable panel 200 are arranged side by side along the first direction.

[0022] In this embodiment, the fixed door leaf 110 is a part that is fixedly installed on the door frame 100, and it includes a fixed door leaf frame 111. The fixed door leaf frame 111 is usually located in the middle area of ​​the door frame 100 along the first direction.

[0023] In this embodiment, the movable door panel 200 is a movable part. It is installed on the door frame 100 through common sliding connection methods such as slide rails and pulleys, and can slide relative to the door frame 100. The movable door panel 200 includes a movable door panel frame 210, which is the main load-bearing structure that is slidably connected to the door frame 100.

[0024] In this embodiment, the screen door 300 includes a screen roll 310 and a vertical handle 320. The screen roll 310 is fixedly installed on the door frame 100 and located at the end of the door frame 100 away from the fixed door leaf 110. The screen roll 310 contains a rollable screen, the movable end of which is connected to the vertical handle 320. Magnets attract each other between the vertical handle 320 and the fixed door leaf frame 111 of the fixed door leaf 110, thereby achieving a detachable magnetic connection between the two.

[0025] In this embodiment, the linkage mechanism includes a latching seat 400 and a latching connector 410. The latching seat 400 is fixedly installed on the movable door frame 210 of the movable door 200, and its overall structure is U-shaped, with the opening of the U-shape facing vertically downwards. Inclined guide slopes are respectively provided on the two inner sidewalls of the U-shaped opening. The latching connector 410 is movably installed on the vertical handle 320 of the screen door 300.

[0026] Specifically, the snap-fit ​​connector 410 is configured to slide relative to the vertical handle 320 and is elastically connected to the mounting part via a spring. The spring ensures that the snap-fit ​​connector 410 is always subjected to a force that tends to move upward, thereby enabling automatic snap-fit ​​engagement with the snap-fit ​​seat 400 located above it.

[0027] During door use, when the movable door 200 is pushed to slide along the door frame 100 to the closed position, the locking seat 400 fixed thereon moves to the corresponding position above the vertical handle 320. The locking connector 410 is pressed down by the guide slope of the locking seat 400, and then springs upward under the drive of the spring force, locking into the U-shaped opening of the locking seat 400, thus achieving mechanical linkage between the movable door 200 and the vertical handle 320 of the screen door 300. At this time, the continued movement of the movable door 200 will pull the vertical handle 320 to move synchronously, thereby controlling the screen to unfold from the sand roll box 310 to cover the doorway, or to rewind the screen back into the sand roll box 310. When it is necessary for the movable door 200 and the screen door 300 to operate independently, the locking connector 410 can be manually moved downwards against the spring force to disengage from the locking seat 400, thus releasing the linkage.

[0028] In a preferred embodiment, the vertical handle 320 is provided with a mounting base 420 corresponding to the snap-fit ​​connector 410; the mounting base 420 is fixedly installed on the vertical handle 320, and a protruding positioning part is provided on the side away from the vertical handle 320; the snap-fit ​​connector 410 is provided with a matching first sliding groove corresponding to the positioning part, which is used to limit the sliding direction of the snap-fit ​​connector 410.

[0029] In this embodiment, the vertical handle 320 is provided with a mounting base 420 for mounting the snap-fit ​​connector 410. The mounting base 420 is fixedly connected to the vertical handle 320. On the side of the mounting base 420 away from the vertical handle 320, there is a positioning part that protrudes outward.

[0030] Accordingly, a first groove matching the shape of the positioning part is formed on the snap-fit ​​connector 410. The positioning part is embedded in the first groove, thereby slidably restricting the snap-fit ​​connector 410 on the mounting base 420. Through the cooperation between the positioning part and the first groove, the snap-fit ​​connector 410 is limited to sliding only along a preset straight direction, which is usually vertical, thereby ensuring that it can be accurately aligned with the snap-fit ​​seat 400 above during movement and achieve reliable snap-fit ​​and separation.

[0031] In a preferred embodiment, the positioning part is further provided with a limiting part corresponding to the snap-fit ​​connector 410, for limiting the snap-fit ​​connector 410 from disengaging from the mounting base 420; the limiting part is T-shaped and located on the side of the snap-fit ​​connector 410 away from the positioning part; the snap-fit ​​connector 410 is provided with a matching second sliding groove and a strip hole located in the second sliding groove corresponding to the limiting part.

[0032] In this embodiment, the positioning portion of the mounting base 420 is further provided with a limiting portion to prevent the snap-fit ​​connector 410 from disengaging. This limiting portion is located on the side of the snap-fit ​​connector 410 facing away from the positioning portion, and its cross-section is T-shaped.

[0033] Accordingly, a second sliding groove matching the shape of the T-shaped limiting part is provided on the snap-fit ​​connector 410. The T-shaped limiting part is embedded in this second sliding groove, forming a sliding guide rail structure together with the positioning part. To facilitate assembly and ensure smooth sliding, a strip-shaped hole extending in the sliding direction is also provided at the bottom of the second sliding groove.

[0034] In this embodiment, through the cooperation of the positioning part with the first slide groove, and the cooperation of the T-shaped limiting part with the second slide groove and the strip hole, the snap connector 410 is securely restricted on the mounting base 420, and can only slide in the preset vertical direction, while effectively preventing it from accidentally coming out of the mounting base 420.

[0035] In a preferred embodiment, the spring is located within the first / second slide groove and above the positioning / limiting portion, for providing a continuous upward driving force to the snap-fit ​​connector 410.

[0036] In this embodiment, the spring is disposed inside the first or second slide groove of the snap-fit ​​connector 410 and is located above the positioning or limiting part of the mounting base 420. One end of the spring abuts against the fixing structure at the top of the slide groove, and the other end is connected to or directly abuts against the corresponding part of the snap-fit ​​connector 410. With this arrangement, the spring continuously applies an upward elastic driving force to the snap-fit ​​connector 410 in its natural or pre-compressed state. This driving force ensures that the snap-fit ​​connector 410 always has an upward tendency in its free state, thereby ensuring that it can automatically and reliably engage with the U-shaped opening of the upper snap-fit ​​base 400 and automatically return to the snap-fit ​​position after manual release.

[0037] In a preferred embodiment, wrenches are provided on both sides of the card connector 410 for driving the card connector 410 to unlock from the card holder 400.

[0038] In this embodiment, when it is necessary to separate the connector 410 from the connector base 400 to release the linkage, the user can press down on both wrenches simultaneously or separately with their fingers. Since the wrenches and connector 410 are fixedly connected or integrally formed, the downward pressure will be directly transmitted to the connector 410 through the wrenches, thereby overcoming the upward elastic force of the spring and driving the connector 410 to slide down along its groove, so that its top comes out of the U-shaped opening of the connector base 400, realizing a quick, effortless and intuitive manual unlocking operation.

[0039] In a preferred embodiment, the movable door frame 210 is further provided with a sealing mechanism on the side near the fixed door 110 for abutting against the fixed door 110 to form a seal; the sealing mechanism includes a sealing strip 500 that is telescopically mounted on the movable door frame 210; the sealing strip 500 extends vertically and includes an inner skeleton and sealing material wrapped around the skeleton; the skeleton includes a semi-circular sealing part and extensions extending radially at both ends of the sealing part.

[0040] In this embodiment, a sealing mechanism is provided on the side of the movable door frame 210 near the fixed door 110. This sealing mechanism is used to ensure that the movable door 200 can tightly abut against the corresponding surface of the fixed door 110 when the movable door 200 is open at any degree, thereby forming an effective sealing barrier between the two doors to prevent mosquitoes, dust and other insects from entering through the gaps.

[0041] In this embodiment, the core component of the sealing mechanism is a retractable sealing strip 500 mounted on the movable door frame 210. The sealing strip 500 extends vertically, and its length is approximately matched with the height of the movable door frame 210.

[0042] In this embodiment, the sealing strip 500 consists of an internal skeleton and a flexible sealing material wrapped around the skeleton. The skeleton includes a main body portion with an outwardly convex semi-circular cross-section, forming the main sealing part. At both ends of the semi-circular sealing part, an extension portion extends horizontally outward along its radial direction. The internal skeleton provides the sealing strip 500 with the necessary support shape and elastic recovery force, while the external flexible sealing material (such as rubber, silicone, etc.) ensures soft and tight contact with the surface of the fixed fan 110 to achieve a good sealing effect.

[0043] In this embodiment, when the movable fan 200 is stationary, the semi-circular sealing portion of the sealing strip 500 presses down onto the fixed fan 110. Under contact pressure, the sealing portion and its outer covering material undergo elastic deformation, tightly adhering to the surface of the fixed fan 110, filling and sealing the potential gap between the two fans.

[0044] In a preferred embodiment, the movable door frame 210 is provided with a matching mounting groove and a cover 211 corresponding to the sealing mechanism; the cover 211 is detachably mounted on the movable door frame 210, and is provided with a matching clearance hole corresponding to the sealing strip 500; the clearance hole extends vertically and its width matches the diameter of the sealing part; the sealing strip 500 is located in the mounting groove and abuts against the fixed door 110 through the clearance hole.

[0045] In this embodiment, a matching mounting groove is machined or provided on the movable door frame 210 corresponding to the installation position of the sealing strip 500. This mounting groove extends vertically and is sized to accommodate and position the sealing strip 500.

[0046] In this embodiment, to facilitate the installation, maintenance, or replacement of the sealing strip 500, a removable cover 211 is provided at the opening of the mounting groove. The cover 211 is fixed to the movable door frame 210 by screws, clips, or similar removable connection methods to close the opening of the mounting groove.

[0047] In this embodiment, a through clearance hole is provided on the cover 211, corresponding to the working part of the sealing strip 500 covered by it. The clearance hole extends vertically, and its width is substantially matched with the diameter of the semi-circular sealing part in the skeleton of the sealing strip 500. This design allows the sealing part of the sealing strip 500 to extend outward through the clearance hole.

[0048] In this embodiment, when the sealing strip 500 is placed in the mounting groove and the cover 211 is installed in place, the semi-circular sealing part of the sealing strip 500 with flexible sealing material passes through the clearance hole on the cover 211 and is exposed. When the movable door frame 210 is in a stationary state, the exposed sealing part directly abuts against the corresponding surface of the fixed door 110, thereby achieving the sealing function.

[0049] In a preferred embodiment, two paddles 510 are provided on both sides of the mounting groove corresponding to the extension portion; one end of the paddle 510 away from the sealing strip 500 is fixedly installed on the movable door frame 210; the distance between the two paddles 510 is relatively smaller than the width of the sealing strip 500, so as to form an overlap with the sealing strip 500.

[0050] In this embodiment, a paddle 510 is provided on each of the two side walls of the mounting groove, corresponding to the positions of the two extensions on the sealing strip 500 frame. The paddle 510 is generally in the shape of a long strip, with one end fixedly installed on the groove wall of the movable door frame 210 by welding, screw connection or integral molding, while the other end is in a free state and extends towards the sealing strip 500.

[0051] Crucially, the distance between the free ends of the two levers 510 is set to be slightly less than the total width of the sealing strip 500 at the corresponding positions. When the sealing strip 500 is installed into the mounting groove, its extensions on both sides are located on the side of the levers 510 closest to the cover 211, and overlap with the levers 510.

[0052] In a preferred embodiment, the interior of the mounting groove is further provided with hydraulic dampers 520 corresponding to the two extensions; the hydraulic damper 520 includes a base fixedly installed on the movable door frame 210 and a piston rod abutting against the sealing strip 500; the end of the piston rod away from the sealing strip 500 extends into the interior of the base and is fitted with a matching piston; the piston is provided with a one-way valve and a through hole to form a bidirectional flow velocity difference; a return spring is provided inside the base on the side of the piston away from the piston rod, and hydraulic oil is provided on the side of the piston close to the piston rod.

[0053] In this embodiment, a hydraulic damper 520 is also provided inside the mounting groove, corresponding to the positions of the extensions on both sides of the sealing strip 500 frame.

[0054] In this embodiment, the hydraulic damper 520 mainly includes a base and a piston rod. The base is fixedly installed on the movable door frame 210, and its interior is a sealed chamber. One end of the piston rod extends from the base and abuts against the corresponding extension of the sealing strip 500, thereby transmitting the movement of the sealing strip 500 to the piston rod.

[0055] In this embodiment, the other end of the piston rod extends into the internal chamber of the substrate, and a piston that matches the inner wall of the chamber is installed at its end. This piston divides the internal chamber of the substrate into two parts.

[0056] In this embodiment, two different fluid channels are provided on the piston: one is a one-way valve, which only allows fluid to pass through from one side of the piston to the other; the other is a through hole, which allows fluid to flow bidirectionally between the two sides of the piston, but its flow cross-sectional area is relatively small, which will generate significant throttling resistance to the fluid flow.

[0057] In this embodiment, a return spring is provided in the internal chamber of the base, on the side of the piston away from the piston rod. One end of the return spring acts on the piston, and the other end acts on the inner wall of the base, providing a tendency for the piston rod to extend outward. The chamber on the side of the piston closer to the piston rod is filled with hydraulic oil.

[0058] In this embodiment, when the movable fan 200 moves, the sealing strip 500 rotates under force, and the corresponding extension compresses the piston rod and crosses the corresponding paddle 510 through deformation; at this time, the hydraulic oil mainly flows to the other side through the one-way valve and will not generate much resistance to the extension; conversely, the piston rod needs a long time to reset; this reset time can ensure that the normal sliding of the movable fan 200 is not affected by the friction of the sealing strip 500.

[0059] In a preferred embodiment, the cover 211 is provided with clearance grooves on both sides of the clearance hole; the clearance grooves extend at an angle to allow the sealing strip 500 to flip laterally.

[0060] In this embodiment, in addition to the vertical clearance hole through which the main body of the sealing strip 500 passes, a clearance groove is also machined on the left and right sides of the clearance hole in the plane direction of the door leaf.

[0061] In this embodiment, the core function of the clearance groove is: when the movable fan 200 moves, the sealing strip 500 is flipped by force, and the corresponding extension can enter the clearance groove, so that the rotation axis of the sealing strip 500 is located at the joint of the sealing part and the extension.

[0062] The above description is merely a preferred embodiment of this application and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the invention involved in this application is not limited to technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the inventive concept. For example, technical solutions formed by substituting the above features with (but not limited to) technical features with similar functions disclosed in this application.
