[0029] The latch seat 501 and the adapter connecting plate 2 have a pre-drilled screw mounting hole 6 at their embedded connection point. After installation, this pre-drilled screw mounting hole 6 coincides with the screw mounting hole 4 on the surface of the adapter connecting plate 2, and the latch seat 501 and the adapter connecting plate 2 are securely connected by the same fastener. This design of coinciding holes and shared fasteners reduces structural weakening caused by additional openings, while enhancing the tightness of the connection between the latch seat 501 and the adapter connecting plate 2, ensuring that they can act synchronously under stress, and improving the overall structural stability.

[0030] In summary, this elevator car interior wall device, which facilitates quick replacement of decorative panels, forms a basic support through the fitting connection between the L-shaped adapter connecting bracket on the back of the decorative panel and the load-bearing bracket. The fastening connection components at both ends enable quick fixation to the elevator car interior wall: the inverted "T"-shaped engaging protrusion of the latch seat slides along the guide slope into the inverted "T"-shaped slot of the fastener seat, completing the downward engagement; when pushed upward, the engaging protrusion slides out of the slot along the slope, achieving disassembly. The overall connection stability is enhanced by the screw mounting holes of the bracket and the fixing holes of the fastener components.

[0031] Furthermore, through this structural design, the device not only enables tool-free and rapid replacement of decorative panels, greatly improving operational efficiency, but also ensures installation accuracy and connection stability by utilizing the positioning structure of bosses and cavities and the fastening method of overlapping holes. At the same time, the flush design of each component surface takes into account both the aesthetics and safety of the elevator interior, effectively solving the problems of cumbersome operation and poor stability of traditional fixing methods.
