Figure 3 to Figure 4As shown, the outer side wall of the door shaft 30 forms a first contact surface 21 and a second contact surface 41 with the door bracket 20 and the waist link 40 respectively.

[0033] In the trackless sliding door of the present invention, the bottom surface of the door bracket 20 is connected to the door body 10 , and the other surface of the door bracket 20 is connected to one end of the waist connecting rod 40 through the door rotating shaft 30 . A torsion spring 50 is coaxially connected to one end of the door shaft 30, and a first gap eliminating arm 51 abuts against the door body 10 or the door bracket 20, thereby forming a reaction force on the door shaft 30, so that the outer wall of the door shaft 30 contacts the door bracket 20 to form a first contact surface 21, and a second gap eliminating arm 52 abuts against the waist connecting rod 40, so that the outer wall of the door shaft 30 contacts the waist connecting rod 40 to form a second contact surface 41, and the door bracket 20 rotates relative to the door shaft 30 through the first contact surface 21, and the waist connecting rod 40 rotates relative to the door shaft 30 through the second contact surface 41, and the door bracket 20 and the waist connecting rod 40 contact the outer side surface of the door shaft 30 respectively, thereby eliminating the assembly gap between the door shaft 30 and the door bracket 20 and the waist connecting rod 40 respectively, thereby preventing the door from shaking during opening and closing. By installing a torsion spring 50 in the door shaft 30 , the assembly gaps between the door shaft 30 and the door bracket 20 and the waist connecting rod 40 can be eliminated, and the modification cost is low.

[0034] Further, such as Figures 1 to 4 As shown, the door bracket 20 includes two bracket arms 22, the upper ends of the bracket arms 22 are provided with a rotation hole 23, one end of the waist link 40 is rotatably mounted between the two bracket arms 22, one end of the waist link 40 is provided with a shaft hole 42, the door shaft 30 is respectively mounted in the rotation hole 23 and the shaft hole 42, the rotation hole 23 is connected to the door shaft 30 through the first contact surface 21, and the shaft hole 42 is connected to the door shaft 30 through the second contact surface 41. One end of the waist link 40 is mounted between the link bracket arms 22 to prevent the waist link 40 from moving along the axial direction of the door shaft 30 during the rotation process, and to limit the waist link 40. The torsion spring 50 is installed at one end of the door shaft 30, and the reaction force of the first gap elimination arm 51 forms a first contact surface 21 between the inner wall of the rotation hole 23 and the outer wall of the door shaft 30. The second gap elimination arm 52 acts on the waist link 40 to form a second contact surface 41 between the shaft hole 42 and the outer wall of the door shaft 30, thereby eliminating the gaps between the door shaft 30 and the rotation hole 23 and the shaft hole 42. More specifically, the first contact surface 21 and the second contact surface 41 are arranged opposite to each other.

[0035] Further, such as Figure 7As shown, the door shaft 30 includes a first shaft section 31 and a second shaft section 33, one end of the first shaft section 31 is connected to one end of the second shaft section 33, the first shaft section 31 is located at one side of the bracket arm 22, the second shaft section 33 is rotatably connected to the two bracket arms 22 respectively, the second shaft section 33 is rotatably connected to the rotation hole 23 and the shaft hole 42 respectively, the torsion spring 50 is installed on the first shaft section 31, and a retaining ring 32 is connected between the first shaft section 31 and the second shaft section 33, the retaining ring 32 extends in the radial direction of the door shaft 30, and the diameter of the retaining ring 32 is greater than the diameter of the rotation hole 23. By setting the retaining ring 32, it is ensured that the first shaft section 31 is located at one side of the bracket arm 22, and the torsion spring 50 is prevented from falling off during the rotation of the door shaft 30.

[0036] Further, such as Figure 7 As shown, the second shaft section 33 includes a connecting section 34 and an end shaft section 35, one end of the connecting section 34 is connected to the first shaft section 31, and the other end of the connecting section 34 is connected to the end shaft section 35.
