[0037] The stopper 33 is provided on the yielding portion 32 for stopping the wheel body 4. When the movable part 3 abuts against the wheel body 4, the stopper 33 abuts against the wheel body 4. The stopper 33 is provided to prevent the movable part from moving when abutting against the wheel body.

[0038] Among them, the height of the locking groove 11 is greater than or equal to the thickness of the hinge part 21, so that the hinge part can be placed in the locking groove, and the depth of the locking groove 11 is greater than or equal to the width of the hinge part 21, so that the hinge part is not easy to fall off from the locking groove, thereby causing displacement of parts.

[0039] It also includes a cover body 5 arranged corresponding to the opening 10, and an extension is arranged on the inner wall of the shell 1 corresponding to the opening 10, and the cover body 5 and the extension cooperate to cover the opening 10, and the cover body 5 is provided with a through hole 50 for the rotating part 2 to pass through, and the height of the through hole 50 is greater than the thickness of the rotating part 2, and the height of the through hole 50 is greater than or equal to the moving height of the hinge 3, and the rotating part 2 at least partially passes through the through hole 50 and is exposed to the cover body 5. The cover body can protect the internal parts and prevent dust and dirt from entering. The through hole is arranged to expose part of the rotating part so that the user can manually operate the rotating part exposed outside the cover to fix or release the door wheel.

[0040] Among them, a card hole is set on the extended edge, and the cover body 5 is provided with a card block corresponding to the card hole. The cover body 5 is covered on the opening 1 through the cooperation of the card block and the card hole. The card hole and the card block are provided to prevent the cover body from falling off.

[0041] Among them, an assembly groove is provided on the inner wall of the shell 1 and is recessed upward from the bottom of the through hole 10, and the wheel body 4 is provided with an assembly axis corresponding to the assembly groove. The wheel body 4 is rotatably connected to the shell 1 through the cooperation between the assembly axis and the assembly groove, so that the wheel body can rotate.

[0042] Wherein, on one side of the housing 1 opposite to the opening 100, there is an installation hole for installing on the door body. The installation of the installation hole enables the door wheel to be installed on the door body. When the door wheel is installed on the door body and the wheel body is exposed from the bottom frame of the door body, the door wheel plays a role in ensuring the smoothness of the door body during the sliding process.
