Description

Technical Field

[0001] The present invention relates to the technical field of lifting and sliding doors, and in particular to a lifting and sliding door with a buffering and noise reduction function. Background Art

[0002] A lift-and-slide door is a door and window system that combines both "lifting" and "pushing" motions. Its core principle is to lift the door leaf upward using hardware accessories (such as lifting handles and track pulleys), freeing it from the lower track to reduce friction, allowing it to be opened and closed by pushing and pulling. To close, the door leaf is lowered to fit tightly against the track, creating a seal.

[0003] Existing lift-and-slide doors are primarily composed of components such as door frames, door leaves, hardware systems, tracks, and seals. Frames are often made of aluminum alloy, thermally insulated aluminum, or solid wood, offering high strength and corrosion resistance. Door leaves can be paired with glass (such as insulating glass or laminated glass) or panels to meet lighting and sound insulation requirements. The core of the hardware system includes lift handles, drive rods, pulleys, and locking points, which mechanically link to achieve the "lift-push-lock" action. Hardware quality directly impacts the door's service life and operational smoothness. High-quality hardware can withstand tens of thousands of openings. Aluminum alloy frames are highly resistant to deformation and offer low maintenance costs. The lower track is typically designed with a groove to work with the pulleys to reduce friction. Sealing strips (such as EPDM rubber strips) are installed between the door frame and door leaf to enhance waterproofing, sound insulation, and thermal insulation.

[0004] Existing lifting and sliding doors have significant disadvantages in actual application: on the one hand, the sliding door is mainly composed of a door frame and a door leaf, and its overall mass is relatively large. In actual use, when the sliding door is pushed and pulled with force, due to its overall mass, it leads to large inertia, and the door frame is prone to impact the frame supporting the sliding door, causing damage to the entire frame or cracks in the connection between the frame and the wall; on the other hand, traditional sliding doors have delicate parts during the lifting process, and are eroded by the outdoor environment (such as rain, dust, and salt spray) for a long time, and are prone to rust and corrosion, which reduces the connection strength and causes malfunctions in the overall use of the sliding door; in addition, the sliding door is another manifestation of the wall. In addition to reflecting the scenery outside the window, it needs to have a certain noise reduction capability.

[0005] For this reason, a lifting and sliding door with a buffering and noise reduction function is needed. Summary of the Invention

[0006] The present invention proposes a lifting sliding door with a buffering and noise reduction function, which solves the problem in the prior art that during actual use during assembly, when the sliding door is pushed and pulled with force, the inertia is large due to its overall mass, and the door frame is prone to impact the frame supporting the sliding door, causing damage to the entire frame or cracks at the connection between the frame and the wall. In addition, the traditional sliding door has delicate parts during the lifting process, which are easily eroded by the outdoor environment (such as rain, dust, and salt spray) for a long time, are prone to rust and corrosion, and the connection strength is reduced, causing the overall use of the sliding door to malfunction.

[0007] To achieve the above object, the present invention provides the following technical solutions:

[0012] Preferably, the bottom end of the sliding lifting assembly is provided with two groups of limit plates in a parallel structure, the surface of the limit plate is provided with an arc groove, the inside of the arc groove is slidably connected to a sliding rod, the middle end of the sliding rod is sleeved with a force limiting ring for force support, the top of the force limiting ring is fixedly connected to a support plate, the sides of the two groups of limit plates are fixedly connected to a connecting plate, and the inside of the two groups of limit plates are rotatably connected to rollers.

[0013] Preferably, the sliding lifting assembly is connected to each other in groups by connecting plates, and the top port of the support plate is in a fixed connection structure with the lifting assembly.

[0014] Preferably, a vertical plate is provided at the bottom of the lifting assembly, and a sliding groove is provided inside the vertical plate for sliding a first sliding rod, a first limiting groove is slidably connected to the end of the first sliding rod, one end of the first sliding rod is connected to a connecting rod, and a second sliding rod is provided at the end of the connecting rod away from the first sliding rod, and the second sliding rod is slidably connected to the inside of the second limiting groove, and a pulling plate is provided at the middle end of the second sliding rod for pulling the bar lock to slide.

[0015] Preferably, the first limiting groove and the vertical plate are in a sliding structure, the first limiting groove and the sliding lifting assembly are in a fixed connection structure, and the vertical plate is simultaneously sleeved inside the vertical plate and the first limiting groove.

[0016] Preferably, the buffer components are centrally symmetrically distributed on the sides of the slide rail with respect to the middle end of the track groove, and the slide rail and the arc-shaped resistance plate have a resistance effect.

[0017] Preferably, drainage outlets are evenly distributed on the sides of the drainage trough, two groups of soundproof glass are provided, and the two groups of soundproof glass are engaged with the front and rear sides of the sliding door. Glass glue and foam glue are filled between the two groups of soundproof glass and the sliding door, and a space is provided inside the hanging rail for the sliding door to slide vertically.

[0018] The present invention proposes a lifting and sliding door with a buffering and noise reduction function. Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. The present invention provides a buffer assembly to effectively prevent the sliding door from impacting the vertical door frame, thereby causing damage to the entire frame or cracks at the connection between the frame and the wall. Two sets of transverse springs and two sets of longitudinal springs designed with tension in the concave groove can provide a resisting force to the arc-shaped resistance plate. When the slide rail slides, it can rub and collide with the arc-shaped resistance plate. The arc-shaped joint between the arc-shaped resistance plate and the slide rail can effectively buffer the slide rail and prevent the sliding door from impacting the vertical door frame.

[0020] 2. The present invention can realize the lifting effect of the slide rail and the sliding door by providing a sliding lifting assembly. When the sliding door needs to be lifted, the support plate is lifted up under the action of the lifting assembly, which drives the resistance limit ring and the slide rod to slide. The slide rod slides in the arc groove and pulls upward, causing the bottom of the resistance limit ring to no longer resist the sliding lifting assembly, so that the roller contacts the track groove to realize rolling operation, thereby realizing the sliding effect of the slide rail and the sliding door; conversely, the support plate is pressed down, which indirectly drives the resistance limit ring to contact the track groove to perform the supporting operation, the roller is separated from the track groove, and the sliding door is lifted and stabilized.

[0021] 3. The present invention can realize the lifting and pressing effect on the slide rail and the sliding door by setting a lifting assembly. When lifting is required, the bar lock is pulled to drive the pull plate to rise. The pull plate pulls the second sliding rod to slide up in the second limit groove. Through the connection effect of the connecting rod, the first sliding rod is driven to slide upward in the sliding groove of the vertical plate. At the same time, the vertical plate slides to the right, pulling the support plate to move to the upper right, indirectly making the roller contact with the track groove to realize rolling operation, thereby realizing the sliding effect of the slide rail and the sliding door;

[0022] 4. The present invention can effectively prevent long-term erosion from outdoor environments (such as rain, dust, and salt spray) by arranging drainage grooves. Drainage grooves are equidistantly arranged on the outer side of the track groove, which can effectively drain accumulated water and prevent long-term erosion of the slide rail and the track groove, thereby ensuring the service life and smooth operation of the sliding door; by arranging two sets of soundproof glass, glass glue and foam glue are filled between the soundproof glass and the sliding door. If the gap is small (within 2 cm), glass glue can be used to fill it to ensure that it fits tightly with the sliding door; for larger gaps, the foam glue can expand and be fixed in the gap after filling, providing a good sealing effect, which can effectively ensure the sealing of the two sets of soundproof glass and effectively improve a certain noise reduction capability.

The two groups of transverse springs 302 and the two groups of longitudinal springs 303 designed in tension in the concave groove 301 can achieve a resistance effect on the arc-shaped resistance plate 304, and when the slide rail 2 slides, it can rub and collide with the arc-shaped resistance plate 304. The arc-shaped resistance plate 304 and the slide rail 2 are in contact with each other. The arc-shaped design can effectively buffer the slide rail 2 and prevent the sliding door 8 from causing impact on the vertical door frame 8.

[0039] Furthermore, the bottom end of the sliding lifting assembly 4 is provided with two groups of limit plates 401 in parallel structure, the surface of the limit plate 401 is provided with an arc groove 402, the inner sliding connection of the arc groove 402 is connected to a slide rod 403, the middle end of the slide rod 403 is sleeved with a force limiting ring 404 for force support, the top of the force limiting ring 404 is fixedly connected to a support plate 405, the sides of the two groups of limit plates 401 are fixedly connected to a connecting plate 406, and the inner rotation of the two groups of limit plates 401 is connected to a roller 407; the slide rail 2 and the sliding door 9 can be lifted. When the sliding door 9 needs to be lifted, the support plate Under the action of the lifting component 5, 405 rises, which will drive the resistance limit ring 404 and the slide rod 403 to slide. The slide rod 403 slides in the arc groove 402 and pulls upward, causing the bottom of the resistance limit ring 404 to no longer resist the sliding lifting component 4, so that the roller 407 contacts the track groove 1 to achieve rolling operation, thereby realizing the sliding effect of the slide rail 2 and the sliding door 9; conversely, the support plate 405 is pressed down, indirectly driving the resistance limit ring 404 to contact the track groove 1 for supporting operation, the roller 407 is separated from the track groove 1, and the sliding door 9 is lifted to a stable position.

[0040] Furthermore, the sliding lifting components 4 are connected end to end in several groups through the connecting plate 406, and the top port of the support plate 405 is in a fixed connection structure with the pulling component 5; the combination of multiple groups of sliding lifting components 4 can effectively support the sliding effect of the slide rail 2, effectively prevent excessive pressure from causing damage to the track groove 1, and at the same time achieve a convenient sliding effect on the slide rail 2; at the same time, the pulling component 5 can achieve a precise pulling effect on the support plate 405.

[0041] Furthermore, a vertical plate 501 is provided at the bottom of the lifting component 5, and a sliding groove is provided inside the vertical plate 501 for sliding the first sliding rod 502, and the first limiting groove 503 is slidably connected to the end of the first sliding rod 502, and one end of the first sliding rod 502 is connected to a connecting rod 504, and the end of the connecting rod 504 away from the first sliding rod 502 is provided with a second sliding rod 505, and the second sliding rod 505 is slidably connected to the inside of the second limiting groove 506, and the middle end of the second sliding rod 505 is provided with a pulling plate 5 for pulling the bar lock 11 to slide 07; It can realize the lifting and pressing effect on the slide rail 2 and the sliding door 9. When lifting is required, the bar lock 11 is pulled to drive the pull plate 507 to rise, and the pull plate 507 pulls the second sliding rod 505 to slide up in the second limit groove 506. Through the connecting effect of the connecting rod 504, the first sliding rod 502 is driven to slide upward in the sliding groove of the vertical plate 501. At the same time, the vertical plate 501 slides to the right, pulling the support plate 405 to move to the upper right, indirectly making the roller 407 contact with the track groove 1 to realize rolling operation, thereby realizing the sliding effect of the slide rail 2 and the sliding door 9.

[0042] Furthermore, the first limiting groove 503 and the vertical plate 501 are in a sliding structure, and the first limiting groove 503 and the sliding lifting assembly 4 are in a fixed connection structure, and the vertical plate 501 is simultaneously sleeved on the inside of the vertical plate 501 and the first limiting groove 503; the pulling plate 507 pulls the second sliding rod 505 to slide up in the second limiting groove 506, and through the connecting action of the connecting rod 504, drives the first sliding rod 502 to slide upward in the sliding groove of the vertical plate 501, and at the same time, the vertical plate 501 slides to the right, pulling the support plate 405 to move to the upper right.

[0043] Furthermore, the buffer assembly 3 is centrally symmetrically structured about the middle end of the track groove 1 and is equidistantly distributed on the sides of the slide rail 2, and the slide rail 2 and the arc-shaped resistance plate 304 have a resistance effect; the buffer assembly 3 is designed as a centrally symmetrical structure. When the sliding door 9 is pushed and pulled with force, due to its overall mass, it has a large inertia. The buffer assembly 3 can effectively resist and buffer the slide rail 2, preventing the sliding door 9 from causing impact on the vertical door frame 8 that supports the sliding door 9, and preventing the vertical door frame 8 from being damaged as a whole or cracks from occurring at the connection between the vertical door frame 8 and the wall.

[0044] Furthermore, drainage openings 7 are evenly distributed on the sides of the drainage groove 6, and two groups of soundproof glass 10 are provided. The two groups of soundproof glass 10 are engaged with the front and rear sides of the sliding door 9. Glass glue and foam glue are filled between the two groups of soundproof glass 10 and the sliding door 9. The interior of the hanging rail 12 is provided with a space for the sliding door 9 to slide vertically. The design of the drainage groove 6 can effectively prevent long-term erosion by outdoor environment (such as rain, dust, and salt spray). The drainage groove 6 is evenly spaced on the outer side of the track groove 1, which can effectively discharge the accumulated water and prevent the slide rail 2 and the track from being damaged. The channel groove 1 is subjected to long-term erosion to ensure the service life and smooth operation of the sliding door 9; at the same time, by setting two groups of soundproof glass 10, glass glue and foam glue are filled between the soundproof glass 10 and the sliding door 9. If the gap is small (within 2 cm), glass glue can be used to fill it to ensure that it fits tightly with the sliding door 9; for larger gaps, the foam glue can expand and be fixed in the gap after filling, providing a good sealing effect, which can effectively ensure the sealing of the two groups of soundproof glass 10 and effectively improve a certain noise reduction capability.

[0045] Working principle: When the sliding door 9 is closed, it can effectively prevent the outdoor environment (such as rain, dust, and salt spray) from polluting the interior. The drainage grooves 6 are evenly spaced on the outer side of the track groove 1 to effectively drain the accumulated water, preventing the slide rail 2 and the track groove 1 from being corroded for a long time, thereby ensuring the service life and smooth operation of the sliding door 9.

[0046] Secondly, by setting up two sets of soundproof glass 10, glass glue and foam glue are filled between the soundproof glass 10 and the sliding door 9. If the gap is small (within 2 cm), glass glue can be used to fill it to ensure that it fits tightly with the sliding door 9; for larger gaps, the foam glue can expand and be fixed in the gap after filling, providing a good sealing effect, which can effectively ensure the sealing of the two sets of soundproof glass 10 and effectively improve the noise reduction ability to a certain extent;

[0047] When the second locking cam 505 is in the locked position, the first locking cam 506 is released, and the second locking cam 507 is released, so the second locking cam 506 is released, and the second locking cam 507 is released.

[0048] Among them, when the sliding door 9 slides, the two sets of transverse springs 302 and two sets of longitudinal springs 303 designed with tension in the concave groove 301 can realize the resistance effect on the arc-shaped resistance plate 304, and when the slide rail 2 slides, it can rub and collide with the arc-shaped resistance plate 304. The arc-shaped design of the contact part between the arc-shaped resistance plate 304 and the slide rail 2 can effectively buffer the slide rail 2 and prevent the sliding door 8 from causing impact on the vertical door frame 8.

[0049] Finally, after the sliding door 9 slides to the specified position, it needs to be fixed. At this time, the sliding door needs to be pressed down. By depressing the bar lock 11 and performing a series of operations on the lifting component 5, the support plate 405 is pressed down, which indirectly drives the resistance limit ring 404 to contact the track groove 1 to perform the supporting operation. The roller 407 is disengaged from the track groove 1, and the sliding door 9 is lifted and stabilized.

[0050] 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.
