Description

Technical Field

[0001] The present invention relates to furniture, in particular to a straightening device, a door panel and a cabinet. Background Art

[0002] Door panels are commonly used in furniture such as cabinets. Door panel deformation is a common technical issue within the industry. Deformation is particularly severe for taller door panels. Deformation often requires straightening devices to correct it.

[0003] In the prior art, there are generally two straightening methods for straightening devices: 1. The straightening device deforms itself to cause the door panel to deform, thereby achieving a correction effect. This straightening method can make the door panel look beautiful, but the amount of straightening is small. 2. The straightening device is embedded in the door panel, and an adjustment point is set in the middle of the door panel, so that the two ends of the door panel are pulled closer to each other by the straightening device, or the two ends of the door panel are pushed apart by the straightening device, thereby achieving a straightening effect. This straightening method has a large amount of straightening, but it will reduce the beauty of the door panel and the appearance of the whole is poor. The technical defect of the straightening device in the prior art is that the straightening device can usually only straighten the door panel from both ends. Although it can correct a door panel bent into a C shape, it cannot effectively correct a door panel bent into an S shape, making the straightening device less versatile. Summary of the Invention

[0004] The purpose of the present invention is to solve at least one of the technical problems existing in the prior art and to provide a straightening device, a door panel and a cabinet that are versatile and easy to operate.
