Description

Technical Field

[0001] The invention belongs to the technical field of sliding doors, and in particular relates to an ultra-sealed multi-track linked silent sliding door. Background Art

[0002] As a common space partition and decorative element, sliding doors are widely used in home, commercial and industrial scenarios due to their space-saving, flexible opening and closing, and beautiful and practical features.

[0003] However, traditional sliding doors, which only slide horizontally in one direction, often become obstacles when moving furniture, appliances, or large items. When users need to move large items like sofas and refrigerators through balconies or hallways, the sliding door must be fully opened to one side, but the fixed position of the door leaf may occupy critical space in the passage, obstructing the transportation path. If the door opening is not wide enough, users may even have to dismantle the door leaf to pass through, which is both time-consuming and labor-intensive.

[0004] At the same time, sliding doors cannot expand the opening area by rotating like swing doors. Their limitations will pose a safety hazard when responding to emergencies (such as carrying emergency equipment).

[0005] Furthermore, existing sliding doors generally utilize a parallel staggered arrangement, where the two doors open and close via overlapping tracks. However, this structure inevitably creates a gap between the two doors when they are closed. This gap can widen due to track accuracy, door deformation, or installation errors. This allows outside noise and hot or cold air to intrude into the room, reducing living comfort. This problem is particularly prominent in residential buildings facing the street or in public places without central air conditioning.

[0006] Among them, Chinese Patent 201510436619.1 discloses a soundproof sliding door comprising a door frame and a movable door leaf mounted within the door frame. The door frame is separated into a non-contacting inner and outer frame by a partition in the door's interior and exterior directions. The inner and outer frames are each provided with at least one inner and outer filling cavity of varying thicknesses, each filled with sound-absorbing filler. The movable door leaf is provided with soundproof glass. This soundproof sliding door achieves soundproofing through filling cavities of varying thicknesses and effectively enhances the soundproofing effect through the use of multiple soundproofing methods. However, it does not address the issues of insufficient space and inability to rotate during transport, nor does it address the gap between the two sliding doors. Summary of the Invention

[0007] The purpose of the present invention is to solve the problem that sliding doors cannot rotate, which becomes an obstacle when things need to be moved. At the same time, the existing sliding doors are arranged in parallel and staggered with each other, resulting in a large gap between the two sliding doors. External noise and hot and cold air invade the room through the gap, reducing living comfort. An ultra-enclosed multi-track linked silent sliding door is proposed.

[0008] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solution: an ultra-sealed multi-track linkage silent sliding door, comprising:

[0009] A rotatable door connected to a door frame via a hinge, wherein the door frame is mounted on a wall;

[0010] a first sliding door movably connected within the rotatable door;

[0011] and a second sliding door, which is movably connected to the first sliding door; wherein a limiting plate is provided on the top of the rotatable door, and the limiting plate abuts against the door frame.

[0012] As a further description of the above technical solution:

[0013] A first movable groove is provided in the rotatable door, the first sliding door is located in the first movable groove, a plurality of first guide grooves are provided at the top and bottom of the first sliding door, a plurality of first guide rails are provided at the top and bottom of the door frame and the inner wall of the bottom of the rotatable door, and the first guide rails are slidably connected in the first guide grooves.

[0014] As a further description of the above technical solution:

[0015] A second movable groove is provided in the first sliding door, the second sliding door is located in the second movable groove, second guide grooves are provided at the top and bottom of the second sliding door, second guide rails are provided at the top and bottom of the door frame and the inner wall of the bottom of the rotatable door, and the second guide rails are slidably connected in the second guide groove.

[0016] As a further description of the above technical solution:

[0017] The second guide rail is located between the two first guide rails.

[0018] As a further description of the above technical solution:

[0019] A first limiting block is provided on the inner wall of the first moving groove, and a first abutting block is provided on the first sliding door. When the first sliding door is closed, the first limiting block abuts against the first abutting block.

[0020] As a further description of the above technical solution:

[0021] A second limiting block is provided on the inner wall of the second moving groove, and a second abutting block is provided on the second sliding door. When the second sliding door is closed, the second limiting block abuts against the second abutting block.

[0022] As a further description of the above technical solution:

[0023] The rotatable door, the first sliding door and the second sliding door are all provided with double-layer glass.

[0024] As a further description of the above technical solution:

[0025] The inner walls of the first sliding door and the second sliding door facing outward are both provided with L-shaped handles.

[0026] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0027] 1. In the present invention, a rotatable door is provided, which is connected to the door frame through a hinge, the first sliding door is movably connected to the rotatable door, and the second sliding door is rotatably connected to the first sliding door. Because the rotatable door, the first sliding door and the second sliding door are all double-layered glass, the first sliding door and the second sliding door are both located inside the double-layered glass, which reduces noise when moving. When large objects need to be transported, they only need to be stored in the rotatable door, and then the rotatable door can be rotated along the hinge to make room for transportation, thereby improving the user experience.

[0028] 2. In the present invention, a plurality of first guide grooves are provided at the top and bottom of the first sliding door, and second guide grooves are provided at the top and bottom of the second sliding door. The second guide groove is located between the two first guide grooves and is slidably connected in the guide grooves by guide rails throughout the entire process. When closed, the top of the rotatable door abuts against the limit plate, the bottom of the rotatable door abuts against the limit block at the bottom of the door frame, the first abutting block on the first sliding door abuts against the first limit block in the rotatable door, and the second abutting block on the second sliding door abuts against the second limit block on the first sliding door, so that when closed, all directions are tightly fitted, and there is no gap compared to traditional sliding doors, thereby achieving a silent effect.
