Description

Technical Field

[0001] This utility model relates to the field of sliding door hanging technology, and in particular to a concealed sliding door hanging structure. Background Technology

[0002] Sliding doors are a common type of door in homes. They not only provide shelter from extreme heat and cold, wind and rain, but also facilitate air convection and light entry. Initially, sliding doors were only used for bedroom or dressing room wardrobes. However, with technological advancements and the diversification of decoration methods, from traditional board surfaces to glass, fabric, rattan, and aluminum alloy profiles, and from sliding doors and folding doors to partition doors, the functions and applications of sliding doors have been continuously expanding. The uses of sliding doors have become more diverse and abundant. In addition to the most common partition doors, sliding doors are widely used in bookcases, wall cabinets, living rooms, showrooms, and sliding entrance doors. As decoration becomes increasingly personalized, more sliding doors are being used in living rooms as partitions, employing a trackless hanging structure. Hidden sliding doors are also becoming increasingly popular with customers.

[0003] Regarding the existing technology patent CN114809873A, a concealed sliding door hanging structure is disclosed, including a hanging rail, hanging wheels, and a door leaf. Wall panels are installed on both sides of the wall, and a hanging rail cavity is formed between the two wall panels for mounting the hanging rail. The longitudinal depth of the hanging rail cavity is adapted to the longitudinal height of the hanging rail. The hanging rail is fixedly installed in the hanging rail cavity, and the hanging wheels are connected to the door leaf and slidably installed within the hanging rail. The hanging rail includes a hanging rail body, which extends outward to form a fitting plate. The fitting plate is provided with a wall panel connector, which is inserted into the wall panel. This utility model, by matching the longitudinal depth of the hanging rail cavity with the longitudinal height of the hanging rail, conceals the hanging rail within the cavity, effectively ensuring the overall aesthetics of the sliding door and enhancing the user experience. Furthermore, by setting an adhesive plate that fits snugly against the wall panel and installing wall panel connectors on the adhesive plate, the wall panel connectors are directly inserted into the wall panel, achieving the purpose of concealing the wall panel. This results in a well-integrated sliding door hanging structure, eliminating the need for a separate door frame structure, reducing installation steps, improving installation efficiency, and lowering installation costs, thereby reducing user operating costs. This is conducive to the promotion and application of the aforementioned sliding door hanging structure in the market.

[0004] However, the existing connection between the hanging structure and the sliding door frame is a welded structure or fixed with bolts. However, the existing fixing methods are quite common. Both disassembly and installation require a lot of time and effort, and they cannot be quickly disassembled or replaced later, which requires a lot of cost. Utility Model Content

[0005] To overcome the problem that existing sliding door frames and hanging structures are fixed by welding or bolts, which is inconvenient for subsequent disassembly and replacement and easily consumes a lot of time and effort.

[0006] The technical solution of this utility model is as follows: a concealed sliding door hanging structure, including a hanging wheel, an I-shaped connecting block fixedly connected to the outside of the hanging wheel, a sliding door frame snapped into the inside of the I-shaped connecting block, through holes opened on the four ends of the left and right sides of the I-shaped connecting block, threaded grooves opened on the four ends of the left and right sides of the sliding door frame, movable plates crosswise and movably connected to the front and rear ends of the left and right sides of the sliding door frame, fixed holes opened inside the movable plates, a first threaded rod meshing with one side of the threaded groove, a first connecting block fixedly connected to one side of the first threaded rod, a movable groove opened inside the first connecting block, a spring fixedly connected inside the movable groove, a fixed rod fixedly connected to the other side of the spring away from the first threaded rod, L-shaped elastic blocks fixedly connected to the four ends of the first threaded rod away from the first connecting block, a second threaded rod meshing with the other side of the threaded groove away from the first threaded rod, an insert rod fixedly connected to one side of the second threaded rod, a slot opened inside the insert rod, and fixed grooves opened on the four ends of the slot.

[0007] Preferably, the door frame is inserted into the I-shaped connecting block by pushing and pulling, and the first threaded rod and the second threaded rod engage with the threaded groove on the inner wall, so that the insert block and the four L-shaped elastic blocks are inserted into the slots inside the insert rod for fixation. After insertion, the fixing groove is used to reinforce the fixation.

[0008] Preferably, the fastener has an internal cavity, into which the hanging wheel slides and is inserted, and reinforcing plates are fixedly connected to both the left and right sides of the fastener.

[0009] Preferably, the upper surface of the fastener has multiple evenly arranged nailing slots, and the upper surface of the reinforcing plate is fixedly connected to a wall panel fixing structure.

[0010] As a preferred embodiment, the I-shaped connecting block has a snap-fit ​​groove inside, into which the sliding door frame snaps into the snap-fit ​​groove.

[0011] Preferably, the two movable plates are rotatably connected to the sliding door frame by a movable shaft, and the fixed rod is inserted into the fixed hole and passes through the movable plate.

[0012] Preferably, all four L-shaped elastic blocks are inserted into the slots and fixed by the fixing grooves and the insert rods.

[0013] Preferably, the insert block, four L-shaped elastic blocks, and insert rod are all connected to the I-shaped connecting block through through holes, and the second threaded rod is fixedly connected to the second connecting block on the other side away from the insert rod.

[0014] The beneficial effects of this utility model are:

[0015] This concealed sliding door hanging structure works by inserting the sliding door frame into the locking groove, rotating and engaging the first threaded rod into the threaded groove, and engaging the second threaded rod into the threaded groove on the other side. At this time, the insert block and four L-shaped elastic blocks are inserted into the slots inside the insert rod and rotate inside. After insertion, the four L-shaped elastic blocks and the insert rod pass through the fixing groove, thus completing the installation and fixing of the sliding door frame. The easy-to-install sliding door frame saves time and effort and reduces the cost of replacement. Attached Figure Description
