Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] This utility model provides a technical solution:

[0027] Please see Figures 1 to 4 A multi-panel overlapping sliding door includes a frame 1, a first sliding door 3, a second sliding door 4 and a third sliding door 5. The bottom of the frame 1 is fixedly connected to a lower guide rail 2, and the top of the frame 1 is fixedly connected to an upper hanging rail assembly 9. Positioning holes 12 are provided on the bottom of both the left and right sides of the frame 1. The bottom and top left and right sides of the first sliding door 3, the second sliding door 4 and the third sliding door 5 are jointly provided with a moving mechanism 8.

[0028] The moving mechanism 8 includes pulleys 81 fixedly connected to the bottom left and right sides of the first sliding door 3, the second sliding door 4 and the third sliding door 5, upper hanging wheels 83 fixedly connected to the top left and right sides of the first sliding door 3, the second sliding door 4 and the third sliding door 5, and linkage blocks 82 fixedly connected to the bottom left and right sides of the first sliding door 3, the second sliding door 4 and the third sliding door 5.

[0029] A brush strip 11 is fixedly connected to the bottom of the linkage block 82 on the left side;

[0030] The number of pulleys 81 and upper hanging wheels 83 is multiple. The multiple pulleys 81 are slidably connected inside the lower guide rail 2, and the multiple upper hanging wheels 83 are slidably connected inside the upper hanging rail assembly 9.

[0031] There are multiple linkage blocks 82, and each linkage block 82 is L-shaped, with multiple linkage blocks 82 interlocking with each other.

[0032] Sliding handles 6 are provided on the left and right sides of the front end of the first sliding door 3, the second sliding door 4, and the third sliding door 5;

[0033] Each of the two first sliding doors 3 has a pin positioning assembly 10 connected to the bottom of the side furthest from each other. The pin positioning assembly 10 includes a fixed base 101 fixedly connected to the bottom of the two first sliding doors 3 on the side furthest from each other. A pin 102 is slidably connected inside the fixed base 101. A spring 103 is sleeved on the outer surface of the pin 102. The top of the spring 103 is fixedly connected to the top of the fixed base 101, and the bottom of the spring 103 is fixedly connected to the bottom of the fixed base 101. The pin 102 extends through the fixed base 101 into the positioning hole 12.

[0034] By adopting the above technical solution, during use, pulling the latch 102 compresses the spring 103 within the fixed seat 101, causing it to slide. Then, the first sliding door 3 is placed inside the frame 1. Releasing the pull on the latch 102 causes the spring 103 to return to its original position, passing through the fixed seat 101 and engaging with the positioning hole 12, thus improving the stability of the first sliding door 3 during use. Pulling the sliding door handle 6 moves the third sliding door 5, which in turn moves the second sliding door 4 and the first sliding door 3 via the linkage block 82. Simultaneously, the brush strip 11 cleans the interior of the lower guide rail 2. The sliding doors 3, 4, and 5 achieve a stable sliding effect by driving the pulleys 81 and 83 to slide stably within the lower guide rail 2 and upper guide rail assembly 9 during their sliding process. The structural design is more lightweight, enabling the sliding doors 3, 4, and 5 to slide and pull stably. At the same time, the sliding doors 3, 4, and 5 fold together after sliding, greatly reducing the space occupied by the sliding doors and increasing the passage space after the sliding doors are opened. This results in a small footprint, high passage capacity, and simple and convenient operation, thereby improving the utilization rate of the sliding doors.

[0035] Specifically, such as Figures 1-3 As shown, acrylic plates 7 are fixedly connected to the top and bottom of the interior of the first sliding door 3, the second sliding door 4 and the third sliding door 5;

[0036] The acrylic sheet 7 is a transparent sheet and is made of methyl methacrylate.

[0037] By adopting the above technical solution and using the acrylic plate 7, the observation effect of the first sliding door 3, the second sliding door 4 and the third sliding door 5 are satisfied, while the cleanliness of the first sliding door 3, the second sliding door 4 and the third sliding door 5 during use is improved. Moreover, the acrylic plate 7 made of methyl methacrylate has a certain degree of corrosion resistance, which improves the corrosion resistance and vibration resistance of the sliding door.

[0038] Working principle: During use, the pin positioning component 10 ensures the stability of the first sliding door 3 during use. At the same time, the acrylic plate 7 facilitates easy observation of the first sliding door 3, the second sliding door 4, and the third sliding door 5 during use. Pulling the sliding door handle 6 causes the first sliding door 3 to slide within the frame 1. During the sliding of the third sliding door 5, the pulley 81 and the upper hanging wheel 83 slide stably within the lower guide rail 2 and the upper hanging rail component 9. Simultaneously, when the third sliding door 5 slides, it moves the linkage block 82. Multiple linkage blocks 82 interlock, causing the second sliding door 4 and the first sliding door 3 to move during the movement of the third sliding door 5. This design features small footprint, high throughput, simple and convenient operation, and a lightweight overall design that improves corrosion resistance, vibration resistance, and smooth sliding.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
