[0035] For the first sliding mechanism 30 mentioned above, please refer to Figure 3-Figure 4 The first sliding mechanism 30 includes a second slide rail 301 and a first pulley assembly 302. The second slide rail 301 is fixed to the bottom inner wall of the door 80a, and the second slide rail 301 is located below the first slide rail 20. The first pulley assembly 302 is slidably disposed on the second slide rail 301, and the second end of one side of the door body 10 is rotatably connected to the first pulley assembly 302. Specifically, the first pulley assembly 302 includes a first wheel assembly 3021, a rotating shaft 3022, and a sleeve 3023. One end of the rotating shaft 3022 is fixed to the second end of one side of the door body 10, and one end of the sleeve 3023 is provided with a rotating hole 302e. The other end of the rotating shaft 3022 is inserted into the rotating hole 302e, and the other end of the sleeve 3023 is fixed to the first wheel assembly 3021. The first wheel assembly 3021 is slidably connected to the second slide rail 301. The first wheel assembly 3021 includes a first wheel 302a and a support 302b, a sleeve 3023 is fixed to the support 302b, the first wheel 302a is rotatably connected to the support 302b, and the first wheel 302a is rollingly arranged on the second slide rail 301. When the door body 10 is opened at the door 80a, the rotating shaft 3022 rotates relative to the sleeve 3023, so that the door body 10 rotates relative to the door frame 80. During this process, and under the action of external force, the door body 10 can slide relative to the second slide rail 301, that is, the first wheel 302a rolls relative to the second slide rail 301, and the door body 10 can stay at any position of the second slide rail 301 and the door body 10 can rotate relative to the door frame 80 at any position of the second slide rail 301, thereby increasing the flexibility of the door body 10.

[0036] The second slide rail 301 is provided with an arc-shaped protrusion 30a. Figure 3-Figure 4The first wheel 302a is provided with a limiting groove, and the arc-shaped protrusion 30a is matched and connected to the limiting groove. It can be understood that the arc-shaped protrusion 30a is inserted into the limiting groove, so that the second slide rail 301 has a limiting effect on the first wheel 302a, reducing the risk of the first wheel 302a falling off the track.

[0037] For the above-mentioned second sliding mechanism 40, the second sliding mechanism 40 includes a third sliding rail and a third pulley assembly. The third sliding rail is fixed to the top of the doorway 80a, and the third pulley assembly is fixed to the top inner wall of the door body 10. The third pulley assembly is slidably and rotatably arranged on the third sliding rail to realize the sliding or rotation of the door body 10 relative to the door frame 80.

[0038] In some embodiments, the second end of one side of the door body 10 is provided with a fixing groove 10a.

When the latch 50 moves from the preset plug-in position to the preset separation position, the latch 50 drives the lever 602 to move vertically upward, so that the second wheel 604 is separated from the second slide rail 301, so that the latch 50 and the second wheel 604 move synchronously in the vertical direction upward or downward. When the latch 50 moves from the preset separation position to the preset plug-in position, the latch 50 drives the lever 602 to move vertically downward, the second slide rail 301 carries the second wheel 604, and the second wheel 604 can roll relative to the second slide rail 301. The second wheel 604 is carried by the first slide rail 20, so that there is friction between the first slide rail 20 and the second wheel 604. In the present embodiment, when the door body 10 needs to rotate relative to the door frame 80, the second wheel 604 is raised above the second slide rail 301, so that the door body 10 can be easily opened relative to the door frame 80. At the same time, the wear of the second wheel 604 can be reduced, thereby increasing the service life of the second wheel 604.

[0041] In some embodiments, the sliding door 100 further includes a handle 90 and a transmission assembly 95. Figure 6 As shown. The handle 90 is rotatably arranged on the door body 10, and the handle 90 is connected to one end of the rotating assembly, and the other end of the transmission assembly 95 is connected to the latch 50. The handle 90 is used to drive the transmission assembly 95 so that the latch 50 moves vertically upward or downward. Specifically, the transmission assembly 95 includes a transmission box, a rack, a gear and a transmission rod. The transmission box is fixed to the door body 10, the handle 90 passes through the door body 10 and is plugged into the transmission box, the gear is fixed to the end of the handle 90 away from the door body 10, the rack is meshed with the gear, the rack is slidably arranged on the transmission box, and the rack is connected to the transmission rod, and the end of the transmission rod away from the rack is connected to the latch 50. When the user applies an external force to the handle 90, the handle 90 rotates relative to the door body 10, so that the gear rotates, and the gear drives the rack to slide relative to the transmission box, so that the latch 50 moves vertically upward or vertically downward. It should be noted that in the embodiment of the present application, the vertical direction is the direction perpendicular to the ground.

[0042] In some embodiments, the sliding door 100 further includes a rubber strip 70, such as Figure 5 As shown, the rubber strip 70 is wrapped around the first slide rail 20 and the second slide rail 301 , and when the door body 10 closes the door opening 80 a , the rubber strip 70 is held against the door body 10 .

[0043] In the embodiment of the present application, when the latch 50 is located at the preset plug-in position, the latch 50 is plugged into the slide groove 30b, and the door body 10 can slide relative to the second slide rail 301. When the latch 50 is located at the preset separation position, the latch 50 is disengaged from the slide groove 30b, and the door body 10 can rotate around the first pulley mechanism with the center of the first pulley mechanism, thereby greatly increasing the width of the door 80a, making it convenient for users to enter and exit.
