Description

Technical Field

[0001] The invention belongs to the technical field of sliding doors, and particularly relates to a super heavy-duty arc door hanger roller assembly. Background Art

[0002] A sliding door refers to a door whose door body is connected with rollers and can move on a fixed track, also known as a push-pull door. It has the characteristics of easy installation, reusable, industrialized production, fire prevention, environmental protection, etc., and is a common facility in living and working places. An arc sliding door is a relatively common type among sliding doors. Its door body is in an arc shape, usually made of glass, with beautiful curves and unique grandeur. The arc of the arc sliding door can be adjusted according to the on-site situation, and it is widely used in places such as hotels, airports, and large shopping malls.

[0003] The traditional arc sliding door hanger roller structure, such as the anti-drop door body hanging device for an arc translation door disclosed in the utility model patent with the authorization announcement number CN203947931U, includes an arc track, an arc seat plate, and a rolling wheel assembly. The curvature of the arc track is the same as that of the arc seat plate. The rolling wheel assembly slides along the arc track, and the rolling wheel assembly is connected to the arc seat plate. The arc seat plate and the rolling wheel assembly move synchronously. The arc seat plate is fixedly connected to the hanging seat, and the arc door body is fixedly connected to the hanging seat. Since the track is in an arc structure, in order to enable the rolling wheel assembly to roll more smoothly on the track, a groove matching the arc of the arc track is provided in the circumferential direction of the rolling wheel assembly. The rolling of the rolling wheel assembly is restricted by the groove to ensure the stability of the sliding door rolling.

[0004] The above arc sliding door hanger roller structure uses a single roller. As the arc sliding door is used more and more widely and its size is getting larger and larger, when using a single roller, the load-bearing capacity of the wheel is relatively small. If a rolling wheel assembly with a groove as involved in the above prior art is added, a jamming phenomenon will occur, affecting the smoothness of the sliding door movement. Summary of the Invention

[0005] The purpose of the invention is to provide a super heavy-duty arc door hanger roller assembly to solve the problems of insufficient load-bearing capacity of the existing arc sliding door roller assembly using a single roller and easy jamming when using multiple rollers.

[0006] To achieve the above purpose, the technical solution of the invention is as follows: The present invention relates to a super heavy-duty arc door hanger roller assembly, which includes an arc slide rail and a roller set. A curved arc track is provided on the arc slide rail. The roller set includes a hanger, a concave wheel and at least one flat wheel. The concave wheel and the flat wheel are arranged at the same height on one side of the hanger through bearings. Both the concave wheel and the flat wheel cooperate with the curved arc track and roll on the curved arc track. A groove is provided on the circumferential direction of the concave wheel, and the radian of the groove is the same as that of the curved arc track, which is used to engage with the curved arc track during rolling. The flat wheel is used for bearing weight during rolling.

[0007] Preferably, an anti-drop cylinder is provided on the hanger. The anti-drop cylinder is rotatably connected to the hanger through a bearing, and the anti-drop cylinder is arranged below the arc slide rail for holding the arc slide rail.

[0008] Preferably, driven wheels are provided between the concave wheel and the flat wheel, and between adjacent flat wheels. The driven wheels are in contact with the concave wheels and flat wheels on both sides, or in contact with the flat wheels on both sides.

[0009] Preferably, the hanger includes a roller mounting seat for mounting the concave wheel and the flat wheel, and a door hanging mounting seat for mounting the sliding door. A waist-shaped hole is provided on the door hanging mounting seat. The door hanging mounting seat is connected to the roller mounting seat through an adjusting screw and fastened to the roller mounting seat through a fixing screw at the waist-shaped hole.

[0010] Adopting the technical solution provided by the present invention, compared with the prior art, it has the following beneficial effects: 1. The super heavy-duty arc door hanger roller assembly involved in the present invention is provided with multiple rollers, including a concave wheel and at least one flat wheel. Among them, a groove is provided on the circumferential direction of the concave wheel, and the radian of the groove is the same as that of the curved arc track, which is used to engage with the curved arc track during rolling. The flat wheel is used to increase the load-bearing capacity. Through the design of multiple rollers, the overall load-bearing capacity can be improved. When the concave wheel rolls, it will catch the curved arc track to prevent derailment when rolling on the arc slide rail. The flat wheel has no limiting effect on the curved arc track and only provides the bearing capacity. Therefore, the entire hanger roller assembly will not have the problem of jamming, ensuring smooth movement while improving the bearing capacity.

[0011] 2. The super heavy-duty arc door hanger roller assembly involved in the present invention is provided with an anti-drop cylinder on the hanger. The anti-drop cylinder is rotatably connected to the hanger through a bearing, and the anti-drop cylinder is arranged below the arc slide rail for holding the arc slide rail. The anti-drop cylinder cooperates with the concave wheel and the flat wheel to clamp the upper and lower surfaces of the arc slide rail respectively, which can further prevent the sliding door from falling off.

[0012] 3. The super heavy-duty arc door hanger roller assembly involved in the present invention is provided with driven wheels between the concave wheel and the flat wheel, and between adjacent flat wheels, integrating all the rollers into a whole, making the rolling more stable.
