Description

Technical Field

[0001] The utility model relates to the technical field of doors and windows, in particular to a multi-section sliding door. Background Art

[0002] Sliding doors are widely used in various scenarios and are almost applicable to all spaces in a home. However, for factory doorways, retractable doors or segmented suspended doors are mostly used. However, when a retractable door retracts or extends, its whole body moves in a telescopic motion. Regardless of the size of the opening gap, its telescopic energy consumption is relatively large. For a suspended door, it is prone to tilting and is likely to be damaged after long-term use, and its practicability is poor. Therefore, it is necessary to design a multi-section sliding door that is convenient to push and pull in multiple sections, so as to conveniently control the number of sliding doors according to the size of the opening gap. It is especially suitable for situations where the opening gap is small for a long time and the opening gap is large during a specific period, which can reduce energy consumption and has high overall stability.

[0014] For this multi-section sliding door, through the arrangement of the fixed door frame and multiple sliding doors, it is convenient to perform telescoping in multiple sections. Through multiple groups of driving mechanisms, it is convenient to drive in sections. When the opening gap is small, only the front several sliding doors can be opened, so as to reduce energy consumption as much as possible. By arranging a swing door on the sliding door at the free end, when only people need to pass through, only the swing door needs to be opened, thus there is no need to open the entire sliding door, improving the use flexibility. By arranging a locking mechanism, it is convenient to lock the swing door and convenient to open it when needed. This multi-section sliding door is convenient to push and pull in multiple sections, so as to conveniently control the number of sliding doors according to the size of the opening gap.

[0023] Embodiment:

[0024] Please refer to Figures 1-6 , a multi-section sliding door, including a fixed door frame 1 and a plurality of sliding doors 2 that are sequentially nested and guided to slide within the fixed door frame 1. A driving mechanism is provided between the fixed door frame 1 and the adjacent sliding door 2 and between two adjacent sliding doors 2. A swing door 3 is also hinged in the middle of the sliding door 2 at the free end and is equipped with a locking mechanism.

[0025] Specifically, the driving mechanism includes a toothed belt 11, a gear 12, and a driving motor 13. The toothed belt 11 and the gear 12 are respectively arranged on two sliding doors 2 on the front and rear sides. The toothed belt 11 is fixedly installed on the front sliding door 2, the gear 12 is rotatably connected to the rear sliding door 2, the driving motor 13 is fixedly installed on the rear sliding door 2 and drives the gear 12 to rotate, and the gear 12 meshes with the toothed belt 11. Start the driving motor 13 to make the output shaft of the driving motor 13 rotate clockwise or counterclockwise, which is convenient to drive the gear 12 to rotate clockwise or counterclockwise. Through the meshing of the toothed belt 11 and the gear 12, the front sliding door 2 is driven to move forward or retract backward, thus facilitating pushing and pulling.

[0026] Specifically, the locking mechanism includes a card rod 4 rotatably connected to the sliding door 2, and a rotating handle 7 facing the rear side is fixedly installed at the rotating connection between the card rod 4 and the sliding door 2. An arc-shaped card slot 5 compatible with the card rod 4 is provided on the swing door 3, and a slide groove 6 that allows the card rod 4 to rotate circumferentially is provided on the sliding door 2. The card rod 4 can be moved by rotating the handle 7 to be rotated out of the arc-shaped card slot 5 or rotated into the arc-shaped card slot 5. When it is rotated into the arc-shaped card slot 5, the swing door 3 is locked. The setting of the slide groove 6 facilitates the circumferential rotation of the card rod 4, and facilitates the arc-shaped card slot 5 to remain in a vertical free state when contacting the locking of the arc-shaped card slot 5.

[0027] Specifically, support seats 14 are fixedly installed on the front and rear sides of the fixed door frame 1 and the front ends of the multiple sliding doors 2, and guide wheels 15 are fixedly installed on the bottom of the support seats 14 located on the sliding doors 2. Through the arrangement of the support seats 14 and the guide wheels 15, it is convenient to support the multiple sliding doors 2, avoid tilting of the sliding doors 2, and improve the stability of the overall structure.

[0028] Specifically, multiple driving mechanisms are arranged on the rear side, and the rear sides of multiple sliding doors 2 are provided with embedded grooves 10 that are compatible with the toothed belts 11 and the gears 12. They are arranged on the rear side to facilitate control from the inside and avoid damage from the outside.

[0029] Specifically, a limiting guide mechanism is provided between the fixed door frame 1 and the sliding door 2 adjacent thereto, as well as between two adjacent sliding doors 2. The limiting guide mechanism includes a guide groove 8 provided at the bottom of the sliding door 2 located on the front side and a guide slider 9 fixedly connected to the sliding door 2 on the rear side. The guide slider 9 cooperates with the guide groove 8 for guiding. Through the provision of the limiting guide mechanism, guiding limiting is facilitated to avoid mutual escaping and ensure mutual connection.
