Description

Technical Field

[0001] This utility model belongs to the field of sliding door technology, specifically relating to an ultra-heavy-duty arc-shaped door hanger roller assembly. Background Technology

[0002] Sliding doors are doors that move along a fixed track via rollers. Also known as sliding doors, they are easy to install, reusable, industrially producible, fire-resistant, and environmentally friendly, making them common in living and working environments. Curved sliding doors are a particularly common type, featuring a rounded shape, typically made of glass, and possessing a graceful curve and unique style. The curvature of a curved sliding door can be adjusted to suit different site conditions, and they are widely used in restaurants, airports, and large shopping malls.

[0003] Traditional curved sliding door hanger roller structures, such as the anti-fall-off door hanging device for curved sliding doors disclosed in utility model patent CN203947931U, include a curved track, a curved base plate, and a roller assembly. The curved track and the curved base plate have the same curvature. The roller assembly slides along the curved track and is connected to the curved base plate. The curved base plate and the roller assembly move synchronously. The curved base plate is fixedly connected to a hanging seat, and the curved door body is fixedly connected to the hanging seat. Because the track has a curved structure, in order to make the roller assembly roll more smoothly on the track, the circumference of the roller assembly is provided with a groove that matches the curvature of the curved track. The groove restricts the wobbling of the roller assembly during rolling, ensuring the stability of the sliding door's rolling.

[0004] The aforementioned curved sliding door hanger roller structure uses a single roller. As curved sliding doors become more widely used and larger in size, the load-bearing capacity of a single roller is relatively small. If a grooved roller assembly as described in the prior art is added, jamming may occur, affecting the smoothness of the sliding door's movement. Utility Model Content

[0005] The purpose of this utility model is to provide an ultra-heavy-duty arc-shaped door hanger roller assembly to solve the problems of insufficient load-bearing capacity of a single roller in existing arc-shaped sliding door roller assemblies and easy jamming when using multiple rollers.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows:

[0007] This utility model relates to an ultra-heavy-duty arc-shaped door hanger roller assembly, which includes an arc-shaped slide rail and a roller group. The arc-shaped slide rail is provided with a curved track. The roller group includes a hanger, a concave roller, and at least one flat roller. The concave roller and the flat roller are arranged at the same height on one side of the hanger through bearings. Both the concave roller and the flat roller cooperate with the curved track and roll on the curved track. The concave roller is provided with a groove in its circumference, and the curvature of the groove is the same as that of the curved track, so as to engage with the curved track when rolling. The flat roller is used to bear the weight when rolling.

[0008] Preferably, the hanger is provided with an anti-falling cylinder, which is rotatably connected to the hanger via a bearing, and is positioned below the arc-shaped slide rail to hold the arc-shaped slide rail in place.

[0009] 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.

[0010] Preferably, the hanger includes a roller mounting seat for mounting concave wheels and flat wheels, and a sliding door mounting seat for mounting sliding doors; the sliding door mounting seat is provided with a waist hole, the sliding door mounting seat is connected to the roller mounting seat through an adjusting screw, and is fastened to the roller mounting seat through a fixing screw at the waist hole.

[0011] Compared with the prior art, the technical solution provided by this utility model has the following advantages:

[0012] 1. The heavy-duty arc-shaped door hanger roller assembly of this utility model is equipped with multiple rollers, including one concave roller and at least one flat roller. The concave roller has a groove on its circumference, and the curvature of the groove is the same as that of the curved track, which is used to engage with the curved track when rolling. The flat roller is used to increase the load-bearing capacity. The design of multiple rollers can improve the overall load-bearing capacity. When the concave roller rolls, it will engage with the curved track to prevent derailment when rolling on the arc-shaped slide rail. The flat roller does not limit the curved track, but only provides load-bearing capacity. Therefore, the entire hanger roller assembly will not have jamming problems, and while improving the load-bearing capacity, it ensures smooth movement.

[0013] 2. The heavy-duty arc-shaped door hanger roller assembly of this utility model is provided with an anti-falling cylinder on the hanger. The anti-falling cylinder is rotatably connected to the hanger through a bearing, and the anti-falling cylinder is set below the arc-shaped slide rail to hold the arc-shaped slide rail. The anti-falling cylinder cooperates with the concave wheel and the flat wheel to clamp the upper and lower surfaces of the arc-shaped slide rail respectively, which can further prevent the sliding door from falling off.

[0014] 3. The heavy-duty arc-shaped gantry roller assembly of this utility model has driven wheels between the concave wheel and the flat wheel, and between adjacent flat wheels, which unites all the rollers into a whole, making the rolling more stable. Attached Figure Description

Detailed Implementation

[0020] To further understand the content of this utility model, the following embodiments are described in detail. The embodiments are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0021] Example 1:

[0022] See attached document Figure 1 As shown, the heavy-duty arc-shaped door hanger roller assembly involved in this embodiment includes an arc-shaped slide rail 1 and a roller assembly 2.

[0023] See attached document Figure 2As shown, the roller assembly 2 in this embodiment includes a hanger 21, a concave roller 22, and two flat rollers 23.
