[0062] The first connecting portion 622 is arranged in the first mounting slot 6211 away from one end of the first roller portion 624, and the thickness of the end of the first connecting portion 622 in the first mounting slot 6211 is less than the height of the first mounting slot 6211; the end face of the first connecting portion 622 facing the first mounting hole 6212 is provided with a first threaded hole 6221, and the first threaded hole 6221 is in communication with the first mounting hole 6212 and the first mounting slot 6211;

[0063] The upper moving wheel 62 further comprises a first fixing bolt 625, which passes through the first mounting hole 6212, the first mounting slot 6211 and the first threaded hole 6221 to fix the first mounting portion 621 and the first connecting portion 622.

[0064] Specifically, the thickness of the end of the first connecting portion 622 in the first mounting slot 6211 is less than the height of the first mounting slot 6211, so that the end of the first connecting portion 622 away from the first roller portion 624 can be displaced in the up-down direction in the first mounting slot 6211, thereby driving the first roller portion 624 to be displaced in the up-down direction. Since the first roller portion 624 needs to be continuously connected with the first sliding groove 111 in sliding manner, that is, when adjusting the height position of the first connecting portion 622 in the first mounting slot 6211, in fact, the displacement of the first mounting portion 621 together with the upper fixed frame 61 and the sliding door 3 in the height direction is adjusted.

[0065] By setting the first mounting through slot 621 in the first mounting portion 621, setting one end of the first connecting portion 622 in the first mounting through slot 6211, and fixing the first mounting portion 621 and the first connecting portion 622 by the first fixing bolt 625, the structure between the first mounting portion 621 and the first connecting portion 622 is stable, and installation and disassembly are convenient. Specifically, when adjusting the height position of the first connecting portion 622 in the first mounting through slot 6211, since the first fixing bolt 625 is threadedly connected with the first threaded through hole 6221 and is rotationally connected with the first mounting through hole 6212, when the first fixing bolt 625 is rotated, the first connecting portion 622 can be displaced up and down in the first mounting through slot 6211, thereby playing a role of adjusting the height. Further, the two upper moving wheels 62 can be independently adjusted.

[0066] Please refer to Figure 1 and Figure 11 Further, the door frame assembly 1 further comprises a lower door frame 12 which is identical in structure to the upper door frame 11 and symmetrically arranged at the upper and lower ends of the fixed door 4; the front side end surface of the lower door frame 12 is provided with a third sliding groove 121 which is open downward;

[0067] The bathroom linkage three-trip door further comprises a third moving assembly 8 and a fourth moving assembly 9.

[0068] The third moving assembly 8 comprises a lower fixed frame 81 and a lower moving wheel 82, the lower fixed frame 81 is identical in structure to the upper fixed frame 61 and symmetrically arranged at the upper and lower ends of the side sliding door 3, and the lower fixed frame 81 is fixedly connected with the lower moving wheel 82 at both ends along the length direction thereof; the lower end of the lower fixed frame 81 is provided with a fourth sliding groove 811 which is open downward, and the lower moving wheel 82 is slidably connected with the third sliding groove 121.

[0069] The fourth moving assembly 9 comprises a third hanging clamp wheel 91 and a fourth hanging clamp wheel 92, the third hanging clamp wheel 91 is identical in structure to the first hanging clamp wheel 51 and symmetrically arranged at the upper and lower ends of the main sliding door 2, the fourth hanging clamp wheel 92 is identical in structure to the second hanging clamp wheel 52 and symmetrically arranged at the upper and lower ends of the main sliding door 2, the third hanging clamp wheel 91 is slidably connected with the third sliding groove 121, and the fourth hanging clamp wheel 92 is slidably connected with the fourth sliding groove 811.

[0070] Specifically need to explain, the lower door frame 12 with the upper door frame 11 is with the center line of the fixed door 4 parallel to the horizontal plane of the plane as the symmetry plane symmetrically arranged, the lower fixed frame 81 is with the center line of the from sliding door 3 parallel to the horizontal plane of the plane as the symmetry plane symmetrically arranged, the fourth moving assembly 9 with the first moving assembly 5 is with the center line of the from sliding door 3 parallel to the horizontal plane of the plane as the symmetry plane symmetrically arranged;

[0071] By setting the third chute 121 and the fourth chute 811, the lower moving wheel 82 and the third chute 121 are slidably connected, the third lifting clamp wheel 91 and the third chute 121 are slidably connected, and the fourth lifting clamp wheel 92 and the fourth chute 811 are slidably connected, which effectively avoids the third chute 121 and the fourth chute 811 from being affected by dust or other impurities to affect the movement of the main sliding door 2 and the from sliding door 3.

[0072] Further, the door frame assembly 1 further comprises a side door frame 13, and the left and right ends of the upper door frame 11 are fixedly connected with the side door frame 13, and the left side door frame 13 is fixedly connected with the left end of the fixed door 4.

[0073] Further, the bathroom linkage three-trip door can change the door opening direction according to actual installation needs.

[0074] Please refer to Figure 11 and Figure 12 Further, the lower moving wheel 82 comprises a second mounting portion 821, a second connecting portion 822, a second wheel bearing 823, a second roller portion 824, a second fixing bolt 825 and a spring 826, the second mounting portion 821 is detachably connected with the rear side wall of the lower fixed frame 81, and the second mounting portion 821 is located below the fourth chute 811.

[0075] The front side wall of the second mounting portion 821 is provided with a second mounting through slot 8211, one end of the second connecting portion 822 is arranged in the second mounting through slot 8211 and detachably connected with the second mounting portion 821, the other end of the second connecting portion 822 is fixedly connected with the inner ring of the second wheel bearing 823, and the outer ring of the second wheel bearing 823 is fixedly connected with the second roller portion 824, and the thickness of the end of the second connecting portion 822 located in the second mounting through slot 8211 is less than the height of the second mounting through slot 8211.

[0076] The upper wall surface of the second mounting portion 821 is provided with a second mounting through hole 8212, the lower wall surface of the second mounting portion 821 is provided with a second threaded through hole 8213 corresponding to the second mounting through hole 8212, the end surface of the second connecting portion 822 facing the second mounting through hole 8212 is provided with a third mounting through hole 8221, and the second mounting through hole 8212, the second threaded through hole 8213, the third mounting through hole 8221 and the second mounting through slot 8211 are in communication with each other; the second fixing bolt 825 passes through the second mounting through hole 8212, the second mounting through slot 8211, the third mounting through hole 8221 and the second threaded through hole 8213 to fix the second mounting portion 821 and the second connecting portion 822.

[0077] The spring 826 is arranged in the second mounting through slot 8211, and the spring 826 is sleeved on the outer periphery of the second fixing bolt 825, one end of the spring 826 is fixedly connected with the inner wall of the second mounting portion 821, and the other end of the spring 826 is fixedly connected with the second connecting portion 822.

[0078] It should be noted that the lower door frame 12 is the same as the upper door frame 11 in structure and is symmetrically arranged at the upper and lower ends of the fixed door 4; the connection mode between the lower movable wheel 82 and the lower door frame 12 is the same as the connection mode between the upper movable wheel 62 and the upper door frame 11; the thickness of the end portion of the second connecting portion 822 located in the second mounting through slot 8211 is less than the height of the second mounting through slot 8211, so that the end of the second connecting portion 822 away from the second roller portion 824 can be displaced in the up-down direction in the second mounting through slot 8211;

[0079] By setting the spring 826 on the lower moving wheel 82, linkage between the upper moving wheel 62 and the lower moving wheel 82 can be achieved. Specifically, by sleeving the spring 826 on the outer periphery of the second fixing bolt 825, one end of the spring 826 is fixedly connected with the inner wall of the second mounting portion 821, and the other end of the spring 826 is fixedly connected with the second connecting portion 822, so that the displacement of the second mounting portion 821 in the second mounting through slot 8211 is limited by the spring 826. Specifically, when the first connecting portion 622 is displaced in the first mounting through slot 6211, the first mounting portion 621 moves together with the upper fixed frame 61 and the sliding door 3 in the height direction. At this time, the spring 826 in the lower moving wheel 82 is compressed or elongated, thereby adaptively adjusting the displacement of the second connecting portion 822 in the second mounting through slot 8211 in the up-down direction. Specifically, the second fixing bolt 825 is rotationally connected with the second mounting through hole 8212, the second fixing bolt 825 is threadedly connected with the second threaded through hole 8213, and the third mounting through hole 8221 on the second connecting portion 822 is movably connected with the second fixing bolt 825, that is, the second connecting portion 822 can move in the up-down direction of the second fixing bolt 825. The two ends of the spring 826 are fixedly connected with the second mounting portion 821 and the second connecting portion 822 respectively, so that when the spring 826 is compressed or elongated, the second connecting portion 822 moves up and down in the second mounting through slot 8211, so that the upper moving wheel 62 and the lower moving wheel 82 always maintain a compressed state, which can increase the friction between the upper moving wheel 62 and the first sliding groove 111 and the friction between the lower moving wheel 82 and the fourth sliding groove 811, and can effectively avoid the jumping of the upper moving wheel 62 during sliding and the risk of the upper moving wheel 62 falling out of the first sliding groove 111.

[0080] Please refer to Figure 11 and Figure 13 Further, the door frame assembly 1 further comprises a stop block 16, which is fixedly connected with one end of the lower door frame 12 away from the fixed door 4, and is located on the lower side of the third sliding groove 121.

[0081] The stop block 16 comprises a stop portion 161 and an insertion portion 162. One end of the stop portion 161 is arranged at the right side of the third lifting clamp wheel 91, and the other end of the stop portion 161 extends from below the third lifting clamp wheel 91 to the direction of the fourth lifting clamp wheel 92. The upper end surface of the stop portion 161 is provided with an arc-shaped opening 1611 matched with the third lifting clamp wheel 91, and the horizontal left end of the arc-shaped opening 1611 is arranged in an open manner. One end of the insertion portion 162 is fixedly connected with the left end of the stop portion 161, and the other end of the insertion portion 162 is arranged in a downward inclined manner away from one end of the stop portion 161. The third lifting clamp wheel 91 is arranged in the arc-shaped opening 1611, and the insertion portion 162 limits the third lifting clamp wheel 91 from automatically sliding out of the arc-shaped opening 1611. The third lifting clamp wheel 91 is inserted into or separated from the arc-shaped opening 1611 from the insertion portion 162.

[0082] It should be noted that the arc-shaped opening 1611 is matched with the shape of the lifting wheel of the third lifting clamp wheel 91. The third lifting clamp wheel 91 is arranged in the arc-shaped opening 1611, and the insertion portion 162 limits the third lifting clamp wheel 91 from automatically sliding out of the arc-shaped opening 1611. Specifically, the connection between the insertion portion 162 and the stop portion 161 is arranged protruding from the arc-shaped opening 1611, and the third lifting clamp wheel 91 is inserted into or separated from the arc-shaped opening 1611 from the insertion portion 162. That is, when the main sliding door 2 needs to be moved, an external force needs to be manually applied to make the third lifting clamp wheel 91 inserted into or separated from the arc-shaped opening 1611 from the insertion portion 162. After the third lifting clamp wheel 91 is clamped with the stop block 16, the main sliding door 2 is prevented from being randomly moved to affect use.

[0083] Please refer to Figure 10 Further, the bathroom linkage three-trip door further comprises a shielding cover 7. One end of the shielding cover 7 along the width direction of the shielding cover 7 is arranged on the upper end of the main sliding door 2. The other end of the shielding cover 7 along the width direction of the shielding cover 7 extends to the upper side of the first sliding groove 111 in the direction of the upper door frame 11. The two ends of the shielding cover 7 along the length direction of the shielding cover 7 are respectively detachably connected with the first lifting clamp wheel 51 and the second lifting clamp wheel 52.

[0084] By arranging the two ends of the shielding cover 7 along the length direction of the shielding cover 7 to be respectively detachably connected with the first lifting clamp wheel 51 and the second lifting clamp wheel 52, the shielding cover 7 can move along with the movement of the main sliding door 2. When the main sliding door 2 is in a closed state, the gap between the main sliding door 2 and the upper door frame 11 can be covered, dust can be prevented from entering the bathroom, and the heat preservation effect of the bathroom can be ensured.
