[0048] Please refer to Figures 1-9 Some embodiments of this application provide a multi-leaf linkage sliding door, which includes:

[0049] The upper track 1 of the door leaf has multiple downward-facing door track grooves 111;

[0050] Multiple door panels 2, the number of which is the same as the number of door track grooves 111, and the top of each door panel 2 is slidably installed on each door track groove 111;

[0051] Door frame 3 is vertically installed on both sides of the upper track 1 of the door leaf;

[0052] The first fastener 4 is fixed to the ground and installed at the bottom of an outer door leaf 2;

[0053] The linkage spring-loaded wheel assembly 5 is installed at the bottom of the door leaf 2, and multiple door leaves 2 slide and cooperate through the linkage spring-loaded wheel assembly 5.

[0054] Specifically, the upper rail 1 and the frame 3 of the door leaf form a U-shaped frame for installing the door leaf 2, which is fixed to the door opening where the sliding door needs to be installed. In this embodiment, the installer can first assemble the upper rail 1 and the frame 3 of the door leaf onto the U-shaped frame for frame installation, and then install the door leaf 2 on the door rail groove 111 of the U-shaped frame to realize the step-by-step installation of multiple sliding doors.

[0055] More specifically, the door track groove 111 of the upper track 1 of the door leaf is designed according to the number of door leaves 2 to be installed, so as to ensure that each door track groove 111 on the sliding door after installation is equipped with a door leaf 2, and the door leaf 2 can completely cover the entire door opening when fully unfolded.

[0056] More specifically, there are two door leaf frames 3, which are respectively set on both sides of the door opening to support the sides of the entire sliding door; after the door leaf 2 is fully opened, the light bars of the two door leaf 2 on both sides abut against the two door leaf frames 3 respectively.

[0057] More specifically, unlike traditional sliding doors, the multi-leaf linkage sliding door of this application embodiment adds a first fixing member 4 and a linkage spring wheel assembly 5 as bottom support for the door leaf 2. The first fixing member 4 is installed on the ground and is used to lock the bottom of an outer door leaf 2, so that the door leaf 2 can be used as a fixed door leaf 2 and serve as a position reference for the other door leaves 2. The other door leaves 2 slide with the fixed door leaf 2 through the linkage spring wheel assembly 5. During the sliding process, these door leaves 2 are not only limited by the door track groove 111 at the top, but also guided by the fixed door leaf 2, which can effectively solve the problem of door leaf 2 shaking. Without adding a lower track, the stability and safety of the sliding door are effectively improved.

[0058] It should be noted that the fixed door leaf 2 can be one of the two light bars of the door leaf 2 that abut against the door leaf frame 3 after the door leaf 2 is fully opened.

[0059] In this embodiment of the application, a multi-leaf sliding door is provided with a first fixing member 4 and a linkage spring wheel assembly 5 at the bottom of the door leaf 2 as bottom support for the door leaf 2. The first fixing member 4 is used to position and install one door leaf 2, and the linkage spring wheel assembly 5 is used to guide the sliding of multiple door leaves 2. This effectively solves the problem of swaying that the sliding door is prone to during use, ensures the stability and safety of the door leaf 2, and improves the user experience of the sliding door.

[0060] In some preferred embodiments, the door leaf upper rail 1 includes: a plurality of linearly arranged upper rail pieces 11, each upper rail piece 11 having a snap-fit ​​groove 112 on its side, and adjacent upper rail pieces 11 being joined together by second fasteners 12 that are respectively fastened to the two snap-fit ​​grooves 112 on both sides.

[0061] Specifically, adjacent upper rail pieces 11 are joined together by second fixing pieces 12 that are respectively fastened to two snap-fit ​​slots 112 on both sides to form the upper rail of the door leaf 1. This allows the upper rail of the door leaf 1 to be connected without the need for nailing, which has the advantages of convenient and quick splicing. Secondly, the upper rail of the door leaf 1 is made up of multiple upper rail pieces 11. The upper rail pieces 11 can be freely matched according to the usage requirements to form different numbers of door rail slots 111, which can meet the use of door openings of different sizes and be suitable for the installation of different numbers of door leaves 2.

[0062] In some preferred embodiments, the snap-fit ​​groove 112 opens toward the adjacent upper rail piece 11, and the upper and lower side walls are respectively provided with an inwardly facing first protrusion 113 and an inwardly facing second protrusion 114;

[0063] The second fastener 12 includes:

[0064] A baffle 121 is used to isolate adjacent upper rail pieces 11;

[0065] A first retaining strip 122 is set on the upper part of the baffle 121 and fastens to the first protrusion 113;

[0066] A second retaining strip 123 is set at the lower part of the baffle 121 and fastens to the second protrusion 114.

[0067] Specifically, the design of the first locking strip 122 and the second locking strip 123 enables adjacent upper rail pieces 11 to achieve a stable connection through the cooperation of the locking groove 112 and the second fixing member 12; wherein, the setting of the first protrusion 113 and the second protrusion 114 enables the second fixing member 12 to be firmly fastened in the locking groove 112, thereby ensuring a stable connection between the upper rail pieces 11.

[0068] More specifically, in the actual assembly process, the installer can first slide one side of the second fixing member 12 along the length direction of the snap-fit ​​groove 112 into one upper rail piece 11, and then slide the other upper rail piece 11 along the length direction of the snap-fit ​​groove 112 onto the other side of the second fixing member 12 to complete the assembly of the door leaf upper rail 1; in other installation methods, the installer can first align the two upper rail pieces 11, and then simultaneously insert both sides of the second fixing member 12 into the snap-fit ​​grooves 112 of the two upper rail pieces 11 to complete the assembly of the door leaf upper rail 1; both installation methods have the advantage of convenient installation.

[0069] In some preferred embodiments, each upper rail piece 11 has 1-3 door rail slots 111.

[0070] Specifically, such as Figure 10 As shown, this application embodiment provides three styles of upper rail components 11, which can be freely combined to form door leaf upper rails 1 with different numbers of door rail grooves 111 to meet the needs of different numbers of door leaves 2.

[0071] In some preferred embodiments, the door frame 3 includes a plurality of linearly arranged frame pieces 31, with adjacent frame pieces 31 being fixedly connected by bolts.

[0072] Specifically, the frame piece 31 can be designed using various materials and structures, such as aluminum alloy, steel, or other high-strength materials. Stainless steel bolts can be considered for improved corrosion resistance and strength. The bolts can be secured using pre-embedded nuts or direct bolt fixing to ensure a strong and stable connection. Furthermore, the number and distribution of bolts can be optimized based on the size and weight of the frame piece 31 to ensure uniform stress and stability across the entire door frame 3.

[0073] More specifically, such as Figure 11 As shown, this application embodiment provides three styles of frame pieces 31, the width of which corresponds to the three styles of upper rail pieces 11 respectively. These frame pieces 31 can be freely combined to form a door frame 3 that can be used with door upper rails 1 with different numbers of door rail grooves 111, so as to meet the needs of different numbers of door panels 2.

[0074] In some preferred embodiments, the door frame 3 and the door upper rail 1 are fixedly connected by bolts.

[0075] Specifically, the bolted connection between the frame piece 31 and the upper door track 1 further addresses the swaying issue that often occurs during the use of sliding doors. In particular, the bolted fixing method makes the connection between the door frame 3 and the upper door track 1 more secure, reducing door swaying during use and improving the door's stability and safety.

[0076] In some preferred embodiments, the bottom of the door leaf 2 has a first mounting groove 21 and a second mounting groove 22 disposed on both sides of the first mounting groove 21, and the first fastener 4 is installed in the first mounting groove 21 of the door leaf 2 located on the outer side;

[0077] The linkage bouncing wheel assembly 5 includes: bouncing wheel 51 and linkage plate 52. The bouncing wheel 51 is installed in the first mounting slot 21 of the other door panels 2.

[0078] Adjacent door panels 2 are slidably connected by at least one linkage piece 52, which is mounted on a bouncing wheel 51 at one end of the bottom of one door panel 2 and slidably mounted in a second mounting groove 22 at the bottom of the other door panel 2.

[0079] Specifically, the multi-leaf sliding door of this application embodiment achieves sliding connection between door leaves 2 by setting a first mounting groove 21 and a second mounting groove 22 at the bottom of the door leaf 2, and installing a bouncing wheel 51 and a linkage plate 52 in the first mounting groove 21. This design not only enhances the stability of the door leaf 2, but also improves the sliding performance of the door leaf 2. The first fixing member 4 is fixed to the ground, and the door leaf 2 connected to it constitutes the fixed door leaf 2, which can serve as a reference for the bottom sliding direction of the other door leaves 2. The bouncing wheel 51 slides in contact with the ground, and the bottom of the other door leaves 2 slides based on the bouncing wheel 51, which ensures that the sliding of these door leaves 2 is smooth and stable. Moreover, all door leaves 2 slide in cooperation with the linkage plate 52, so that the sliding action of the bottom of the other door leaves 2 is parallel to the fan surface direction of the fixed door leaf 2.

[0080] More specifically, such as Figure 2 As shown, one end of the linkage plate 52 is fixed to the spring wheel 51, and the other end has a sliding block that can be slidably installed in the second mounting groove 22; the sliding block preferably includes a guide wheel 522 whose axis is parallel to the fan surface of the door leaf 2.

[0081] In some preferred embodiments, the bouncing wheel 51 includes:

[0082] A mounting bracket 511 is installed at the bottom of the door leaf 2, a spring wheel 512 is installed on the mounting bracket 511, and a spring plate 513 that bends upward and presses against the bottom of the door leaf 2 is connected to the top of the mounting bracket 511.

[0083] Specifically, one end of the linkage piece 52 is fixed to one side of the mounting bracket 511.

[0084] More specifically, the spring wheel 512 enables the door leaf 2 to slide in contact with the ground, ensuring that the bottom of the door leaf 2 is more stable and smooth when sliding. Secondly, the multi-leaf linkage sliding door of this application embodiment is provided with an upwardly curved spring plate 513 that presses against the bottom of the door leaf 2, so that the mounting bracket 511 and the door leaf 2 have a close contact relationship, ensuring that the mounting bracket 511 can be firmly installed at the bottom of the door leaf 2 without the need for fasteners such as bolts, simplifying the installation method of the spring wheel 51 and improving the stability of the door leaf 2.

[0085] It should be noted that the spring wheel 512 is a roller assembly with adjustable wheel height. It generally includes a fixing screw that limits the spring height and an adjusting screw that adjusts the roller height, so that the spring wheel 512 can be adjusted to achieve a stable contact with the ground according to the ground characteristics, so as to prevent the spring wheel 512 from jumping up and down due to uneven ground. The specific adjustment method will not be described in detail here.

[0086] In some preferred embodiments, the first mounting groove 21 is a T-shaped groove, and the top of the mounting bracket 511 slides in conjunction with the T-shaped groove.

[0087] Specifically, the mounting bracket 511 has a third protrusion on both sides of its top, which inserts into the branch slots on both sides of the T-slot.

[0088] More specifically, the first mounting groove 21 is designed as a T-shaped groove. This design allows the mounting bracket 511 to fit more stably with the bottom of the door leaf 2. Then, the mounting bracket 511 can be positioned and installed by pressing the top of the T-shaped groove with the spring plate 513.

[0089] More specifically, the third protrusions on both sides of the top of the mounting bracket 511 are inserted into the branch slots on both sides of the T-slot. This structure ensures that the mounting bracket 511 is limited in the T-slot and, together with the spring plate 513, realizes the installation and fixation of the entire bouncing wheel 51, thereby improving the stability of the door leaf 2.

[0090] In some preferred embodiments, the hook of the door leaf 2 is fitted with a magnetic strip 6.

[0091] Specifically, in this embodiment, adjacent door panels 2 are magnetically sealed by magnetic strips 6 on hooks after being unfolded.

[0092] More specifically, the magnetic strip 6 is preferably snap-fitted onto the hook portion of the door leaf 2. In this embodiment, the multi-leaf sliding door utilizes magnetic force to ensure that adjacent door leaves 2 fit tightly together when closed, thus achieving a sealing effect. As a preferred embodiment, the magnetic strip 6 can be made of a strong magnetic material to ensure the stability and durability of the magnetic attraction effect. Furthermore, the installation position and angle of the magnetic strip 6 can be adjusted according to actual needs to adapt to different door leaf 2 sizes and shapes.

[0093] More specifically, the magnetic attraction of the magnetic strip 6 can enhance the connection stability between the door panels 2 after they are unfolded, reduce the shaking of the door panels 2, and thus improve the user experience and security of the door.

[0094] In some preferred embodiments, the door frame 3 is provided with a third mounting groove 32, and the third mounting groove 32 is provided with anti-collision rubber strips 7 and / or weatherstripping 8.

[0095] Specifically, the anti-collision strip 7 and / or weatherstripping 8 provided on the third mounting groove 32 can effectively prevent the movable door leaf 2 from colliding with the frame when closed, thereby reducing noise generation. It can also further enhance the sealing effect of the door leaf 2 after it is fully opened, reducing the penetration of air and sound. The anti-collision strip 7 can be made of elastic material to provide better cushioning effect, while the weatherstripping 8 can be made of soft and wear-resistant material to ensure sealing performance for long-term use.

[0096] In some preferred embodiments, the first fixing member 4 includes a fixing part 41 fixed to the ground and a limiting part 42 fixed to the fixing part 41 and fixed in a first mounting groove 21 located at the bottom of the outer door leaf 2.
