Description

Technical Field

[0001] The utility model relates to the technical field of a double-leaf sliding door, in particular to a double-leaf sliding door. Background Art

[0002] Sliding doors are door panels that move horizontally via guide rails. They are commonly used in home balconies, kitchens, and bathroom doors. They are also used in factory doors because they save space and are easy to operate. Sliding doors come in many types depending on actual needs, and the most common one is the double-leaf structure.

[0003] A double-leaf sliding door refers to a door with two door panels. The traditional double-leaf sliding door is a stacked structure, that is, the two door panels can overlap each other to achieve the function of opening and closing, while a single-leaf door refers to a single door panel, which is often used in locations where the door opening space is limited. The slide rail is set on the wall, and the door panel will be retracted into one side of the wall when it is opened. Because the double-leaf door is basically a stacked structure, and the door panels that are parallel when unfolded will take up a large space like blinds after folding, a double-leaf sliding door is set up for this purpose.

[0014] The utility model will be further described below in conjunction with the accompanying drawings.

[0015] Please refer to Figure 1-4 The utility model discloses a double-leaf sliding door, comprising a slide rail 1, a first door panel 2 is arranged below the slide rail 1, a second door panel 3 is arranged on one side of the first door panel 2, a moving groove 7 is opened on the side wall of the first door panel 2 close to the second door panel 3 and opposite to the second door panel 3, a slider 8 is slidably connected in the moving groove 7, the slider 8 is an I-shaped structure, a rotating column 9 is rotatably connected in the middle of the slider 8, an adjusting column 10 is telescopically connected in the rotating column 9, an end edge of the adjusting column 10 away from the rotating column 9 is rotatably connected to a rotating shaft 11, a connecting column 12 is fixedly connected to one side of the rotating shaft 11, and the connecting column 12 is fixedly connected to one end side wall of the second door panel 3 through its end away from the rotating shaft 11;

[0016] A tension spring is fixedly connected to one end of the rotating column 9 close to the slider 8, and one end of the adjusting column 10 located in the rotating column 9 is fixedly connected to the tension spring. The rotating shaft 11 and the adjacent end of the connecting column 12 are established as corresponding inclined structures, and a stopper 13 is fixedly connected to the inner wall of the opening at one end of the movable groove 7.

[0017] The technical effect of this solution is that the movement groove 7 can make the second door panel 3 move more smoothly. When the slider 8 contacts the block 13, it will drive the first door panel 2 to slide synchronously along the slide rail 1. The rotation of the rotating column 9 can drive the second door panel 3 to move, so that the rotating shaft 11 and the connecting column 12 are adjusted from a right angle state to a horizontal state. At this point, the second door panel 3 is moved to a position at the same level as the first door panel 2, and then the tension spring in the rotating column 9 is driven to bring the first door panel 2 and the second door panel 3 closer to each other, realizing the adjustment function of the double leaves from stacking to horizontal, increasing the practicality of the sliding door, and being able to achieve flexible adjustment of the two methods without increasing the additional occupied space.

[0018] The top side wall of the adjacent end of the No. 1 door panel 2 and the No. 2 door panel 3 is fixedly connected with a column 14, and the top of the column 14 is rotatably connected with a turntable 18. The bottom of the slide rail 1 is an open structure. The middle side wall in the slide rail 1 is fixedly connected with a partition 15. Two slide grooves are opened in the slide rail 1 through the partition 15. The inner wall opposite to each slide groove is opened with a side groove 17. The turntable 18 extends into the corresponding slide groove and is rotatably connected in the side groove 17. A connecting hole 16 is opened at one end of the partition 15, and a blocking plate 21 is fixedly connected to one end of one of the slide grooves close to the connecting hole 16.

[0019] The technical effect of this solution is that a connecting hole 16 is provided at one end of the connecting plate 5, so that the turntable 18 connected to the second door panel 3 can be adjusted to the other side, so that the two turntables 18 are at the same level, providing movement space for the adjustment of the second door panel 3 and ensuring the smoothness of the movement and adjustment. In order to ensure the smoothness of the movement of the second door panel 3 and the first door panel 2, the connecting plate 5 and the ball 6 are installed at the bottom thereof. Because the ball 6 is a spherical structure, it can realize rolling in the front position, providing support for the movement of the second door panel 3 while ensuring that the second door panel 3 moves more smoothly.

[0020] A connecting plate 5 is fixedly connected to the bottom of the door panel No. 1 2 and the door panel No. 2 3 and near the edges at both ends. A spherical ball 6 is rotatably connected to the middle of the bottom end of the connecting plate 5. A movable groove 19 is opened in the middle of the side wall of one end of the door panel No. 2 3. A spring 20 is fixedly connected to the inner wall of the movable groove 19. A telescopic pad 4 is telescopically inserted in the movable groove 19. The spring 20 is fixedly connected to one side wall of the telescopic pad 4 through one end thereof.

[0021] The technical effect of this scheme is that because the door opening is completely closed when the second door panel 3 and the first door panel 2 are unfolded, a movable groove 19 is set to ensure the smooth progress of subsequent adjustments. When the second door panel 3 is unfolded, the telescopic pad 4 will be driven to fit and contact one side of the door opening. At this time, pulling the second door panel 3 with force will compress the telescopic pad 4 into the movable groove 19, so that the second door panel 3 can continue to move and adjust. When the rotating column 9 is pulled to a horizontal state, the second door panel 3 is pulled sideways in the direction of the first door panel 2. When the second door panel 3 is flush with the first door panel 2, the pulling force on the second door panel 3 is released, so that it fits with one end of the first door panel 2 under the action of the spring 20 and the tension spring. At the same time, thanks to the drive of the spring 20, the telescopic pad 4 can fit the door opening, ensuring the closure of the door opening after unfolding.

[0022] Specifically, when the utility model is used, the slide rail 1 is installed at a specified position, and then the second door panel 3 is pulled to move and unfold along the slide rail 1. As the second door panel 3 moves, when the slider 8 is in contact with the stopper 13, the first door panel 2 will be driven to unfold along the slide rail 1. As the first door panel 2 moves, the turntable 18 connected to the first door panel 2 will be in contact with the blocking plate 21. At this time, the first door panel 2 cannot be pulled, but the second door panel 3 can continue to be pulled because of the relationship between the telescopic pad 4 and the movable groove 19, so that the rotating column 9 can be driven to gradually adjust to a horizontal state. At the same time, the turntable 1 connected to the second door panel 3 is 8 will also move to the corresponding position through the connecting hole 16. After the No. 2 door panel 3 is adjusted to a position flush with the No. 1 door panel 2, the restriction on the No. 2 door panel 3 is released, so that it is fitted with the No. 1 door panel 2 under the drive of the spring 20 and the tension spring. When it needs to be stored, the No. 2 door panel 3 is now turned outward, and then the No. 2 door panel 3 is pushed to adjust the connecting hole 16 and the rotating column 9 to the original state and position, and then the No. 2 door panel 3 is moved to overlap on one side of the No. 1 door panel 2. When the slider 8 contacts the side wall of the end of the movable groove 7 away from the block 13, it will drive the No. 1 door panel 2 to retract synchronously, thereby realizing the storage and closure of the double leaves.
