Description

Technical Field

[0001] This utility model relates to the field of sliding door technology, specifically a concealed bottom sliding track three-opening combination sliding door. Background Technology

[0002] A three-panel sliding door is a sliding door consisting of three panels. Compared to a traditional double-panel sliding door, a three-panel sliding door has an extra panel, which increases the opening space of the sliding door, making the space appear more spacious.

[0003] In the current three-panel sliding door, three tracks are installed under the three door panels for sliding. However, the openings of the tracks are always exposed during use, and impurities easily accumulate in the gaps between the tracks, causing them to become clogged with impurities over a long period of time. The narrow gaps in the tracks make them difficult to clean. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a concealed bottom sliding track three-opening combination sliding door, which solves the problem that the opening of the track is always exposed, and that impurities easily accumulate in the gaps of the track, causing the track to be filled with impurities for a long time.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a concealed bottom sliding rail three-panel combination sliding door, comprising a sliding door frame and several sliding door frames located inside the sliding door frame. A door panel is fixedly installed inside the sliding door frame. A slide rail seat is fixedly connected to the bottom of the sliding door frame. Several sliding grooves are provided on the top of the slide rail seat. Several transmission wheels are rotatably connected to the front and rear of the inner cavity of the sliding grooves via bearings. Two moving blocks are fixedly connected to the bottom of the sliding door frame. A transmission belt is fixedly connected to the opposite sides of the two moving blocks. The surfaces of the several transmission wheels are connected to the transmission belt for transmission.

[0006] Preferably, the top of the inner cavity of the sliding door frame is provided with a plurality of limiting grooves, and the top of the sliding door frame is fixedly connected with a limiting plate that cooperates with the limiting grooves.

[0007] Preferably, a plurality of connecting blocks are fixedly connected to the front and rear parts of the inner cavity of the sliding groove and between the two transmission wheels, and a support plate is fixedly connected to the opposite sides of the plurality of connecting blocks.

[0008] Preferably, the bottom of the movable block is fixedly connected with a roller.

[0009] Preferably, both sides of the inner cavity of the sliding groove are fixedly connected with a sealant plate that works in conjunction with the transmission belt.

[0010] Preferably, protective pads are fixedly installed on both sides of the inner cavity of the sliding door frame.

[0011] Beneficial effects

[0012] This utility model provides a concealed bottom sliding track three-panel combination sliding door. Compared with existing technologies, it has the following advantages:

[0013] (1) This utility model has multiple transmission wheels installed inside the sliding groove. When the sliding door frame moves, it will drive two moving blocks to move. The two moving blocks will drive the transmission belt to drive on the multiple transmission wheels, so that the sliding door frame, the two moving blocks and the transmission belt achieve a complete transmission effect of the conveyor belt. When the sliding door frame moves to any position, the transmission belt will always cover the opening of the sliding groove, which can effectively prevent impurities from falling into the sliding groove. There is no need to clean the sliding groove regularly, and the opening of the slide rail can be well hidden.

[0014] (2) This utility model moves two moving blocks by pushing and pulling the door frame. The rolling wheels on the two moving blocks will roll on the support plate, so that the sliding door frame can move in the slide rail through the rolling wheels. This can effectively reduce the friction when the door panel moves, making it more convenient to push the door panel to move. Attached Figure Description

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0023] Please see Figure 1-6 This utility model provides a technical solution: a concealed bottom sliding rail three-opening combination sliding door, including a sliding door frame 1 and several sliding door frames 2 located inside the sliding door frame 1. The front and rear parts of the leftmost sliding door frame 2 and the rightmost sliding door frame 2 are fixedly connected to handles. A door panel 3 is fixedly installed inside the sliding door frame 2. A slide rail seat 4 is fixedly connected to the bottom of the sliding door frame 1. Several sliding grooves 5 are opened on the top of the slide rail seat 4. Several transmission wheels 6 are rotatably connected to the front and rear parts of the inner cavity of the sliding groove 5 through bearings. Two moving blocks 7 are fixedly connected to the bottom of the sliding door frame 2. A transmission belt 8 is fixedly connected to the opposite side of the two moving blocks 7. The front and rear sides of the transmission belt 8 are in contact with the front and rear parts of the inner cavity of the sliding groove 5. The surfaces of the several transmission wheels 6 are connected to the transmission belt 8.

[0024] Furthermore, in order to increase the stability of the sliding door frame 1, several limiting grooves 9 are provided on the top of the inner cavity of the sliding door frame 1, and a limiting plate 10 that cooperates with the limiting grooves 9 is fixedly connected to the top of the sliding door frame 2.

[0025] Furthermore, in order to reduce the friction of the sliding door frame 2, several connecting blocks 11 are fixedly connected to the front and rear of the inner cavity of the sliding groove 5 and between the two transmission wheels 6. A support plate 12 is fixedly connected between the opposite sides of the several connecting blocks 11. A rolling wheel 13 is fixedly connected to the bottom of the moving block 7.

[0026] Furthermore, in order to cover the gap between the surface of the transmission belt 8 and the inner wall of the sliding groove 5, a sealant plate 14 for use with the transmission belt 8 is fixedly connected to both sides of the inner cavity of the sliding groove 5.

[0027] Furthermore, in order to protect the sliding door frame 2, protective pads 15 are fixedly installed on both sides of the inner cavity of the sliding door frame 1. The protective pads 15 are rubber.

[0028] It should be noted that when the sliding door frame 2 is pulled too hard and collides with the inner wall of the sliding door frame 1, the protective pad 15 cushions the impact force of the sliding door frame 2.

[0029] When in use, by pulling the right handle, the rightmost sliding door frame 2 is moved to the left. When the rightmost sliding door frame 2 moves in front of the middle sliding door frame 2, the two rightmost sliding door frames 2 are pushed at the same time to overlap the three sliding door frames 2.

[0030] As the sliding door frame 2 moves to the left, it drives two rolling wheels 13 to roll on the support plate 12 via two moving blocks 7. At the same time, the leftward movement of the two moving blocks 7 drives the transmission belt 8 to move on multiple transmission wheels 6, so that the transmission belt 8 moves synchronously with the movement of the sliding door frame 2. When the transmission belt 8 is in motion, it always covers the opening of the sliding groove 5. Meanwhile, the limiting plate 10 on the sliding door frame 2 slides in the limiting groove 9 to limit the movement of the sliding door frame 2.
