Description

Technical Field

[0001] The utility model relates to a hinge, in particular to a cabinet door hinge with a sealing function for a plate installation hole. Background Art

[0002] At present, the door panels used in panel furniture such as kitchen cabinets and bathroom cabinets are made of particleboard or medium-density fiberboard as the base material. These plates are artificial boards made by gluing various granular wood chips and other materials with formaldehyde-containing adhesives. Such plates are widely used in furniture manufacturing, but the adhesives used in their production contain formaldehyde, and the volatilization of formaldehyde poses potential hazards to the environment and human health.

[0003] In the prior art, when used to make furniture door panels, connectors are generally used, such as three-in-one connectors. The three-in-one connectors are mainly used for connecting the horizontal and vertical plates in panel furniture, while the hinge is mainly used as the hinge of the door panel. On the furniture door panel, a round flat-bottom blind hole for installing the connector, that is, the so-called hinge hole, needs to be processed, then the connector is embedded, and then fixed with self-tapping screws. However, due to the limitations of the connector material, manufacturing process, internal structure and function, the part of the connector connected to the door panel is not completely round, especially there are gaps on the surface. These gaps and pores not only affect the tightness of the connection, but also provide a channel for the overflow of harmful volatile gases.

[0004] Specifically, due to the gap between the connector and the door panel, harmful volatile gases such as formaldehyde will pass through the gap between the hinge cup and the round hole of the door panel, especially overflow from the gap position. At the same time, due to the change of humidity around the hinge hole position, the humid water vapor will also penetrate into the interior of the furniture door panel material through the gap and the hole. The penetration of this humid water vapor will cause the door panel material to be affected with damp and expand, and the internal structure will change, affecting the service life and function of the door panel. Especially in the application of bathroom cabinet door panels, the penetration of water vapor is more serious, and the waterproof and moisture-proof problems are more prominent. Therefore, it is necessary to make further improvements. Summary of the Utility Model
