Wall panel corner system

Abstract

This invention provides a matching wall panel corner system, relating to the field of building wall panel installation technology. The matching wall panel corner system includes a wall, a first wall panel, and a second wall panel. In this invention, the connecting seat is connected to the A and B sides of the wall via two sets of connecting plates. The corner guard is engaged with the connecting seat via a connecting rod and a connecting sleeve. The dimensions of the wall panel facing the corner do not need to be precisely controlled, as long as it does not interfere with the connecting seat and can be covered by the corner guard. This greatly reduces construction difficulty and increases construction speed. The connecting rod can slide up and down along a groove to adapt to the height of the installed connecting seat. When the connecting rod is inserted into the connecting sleeve, the outer toothed ring undergoes a process of avoidance and recovery due to its own elasticity, ultimately forming a snap-fit ​​through the engagement of the outer and inner toothed rings. When the corner guard needs to be removed, the connecting rod is pulled outwards, allowing the outer toothed ring to again avoid the snap-fit ​​through its own elasticity.

Description
