Door lock panel assembly

Abstract

The invention discloses a door lock panel assembly which comprises an external trimming plate and a structural plate. The door lock panel assembly is characterized in that a detachable fixing and clamping structure used for fixing the external trimming plate is arranged on the structural plate, and clamping blocks used for being clamped into the fixing and clamping structure are arranged on the external trimming plate; and the fixing and clamping structure comprises clamping grooves, and a fixing groove communicates with one end of the inner side of each clamping groove. Since the external trimming plate is fixed to the structural plate, fixing is very convenient, and detaching and replacing are also convenient and do not need professionals or professional tools, and when the external trimming plate is scratched or contaminated, detaching and replacing are convenient, and the structural plate is not prone to being damaged. The structure is simple, the cost is low, the external trimming plate is replaced conveniently, fixing is firm, the service life is long, and a user can replace the external trimming plate at any time according to interests.

Description

[0001] 【Technical field】 [0002] The invention relates to a door lock panel assembly, in particular to a square door lock panel assembly. [0003] 【Background technique】 [0004] Some of the panels of the existing square door locks adopt a one-layer structure, and those with a one-layer structure directly fix the panels on the door. Moreover, the panel of the original model must be retrieved, otherwise it may not match the door lock; some adopt a two-layer structure, the inner layer is fixed to the door, and the outer layer is fixed to the inner layer. The fixing structure between the structural panels is complicated, the manufacturing cost is high, and the disassembly is inconvenient. Professionals need to use professional tools to disassemble. Sometimes the structural panels and doors may be damaged when the exterior trim panels are removed. The boards and exterior trim panels are all replaced, and sometimes the doors are replaced to avoid being picked by thieves. At the sa...

[0004] Some of the panels of the existing square door locks adopt a one-layer structure, and those with a one-layer structure directly fix the panel on the door. Moreover, the panel of the original model must be retrieved, otherwise it may not match the door lock; some adopt a two-layer structure, the inner layer is fixed to the door, and the outer layer is fixed to the inner layer. The fixing structure between the structural panels is complicated, the manufacturing cost is high, and the disassembly is inconvenient. Professionals need to use professional tools to disassemble. Sometimes the structural panels and doors may be damaged when the exterior trim panels are removed. Replace all panels and exterior panels, and sometimes replace the door to avoid being picked by thieves. At the same time, it is not convenient to install. The fixation between the exterior panel and the structural panel is not firm, it is loose, and it is easy to fall
